feat(aws-lambda): arm64 video function image from the handler ZIP (#6064)
* feat(aws-lambda): arm64 video function image from the handler ZIP The image is the release handler ZIP with its x86 ffmpeg and Chrome swapped for the native ffmpeg tree and the sha256-pinned Sparticuz arm64 Chrome pack, so the x86 and arm64 functions run the same handler code. The image stage only copies, so any host builds it. CI builds it and runs ffmpeg, a real Chrome render and the Lambda runtime on an ARM runner. * fix(aws-lambda): launch Chrome in the image smoke the way Lambda does @sparticuz/chromium inflates its AL2023 libraries only when AWS_EXECUTION_ENV names a Node runtime; Lambda sets it, a bare docker run does not. The workflow also runs on @sparticuz/chromium bumps and handler ZIP layout changes, which re-stage the image. * fix(aws-lambda): smoke the arm64 image through its own Lambda runtime The smoke is now a handler invoked through the image's entrypoint, whose bootstrap sets AWS_EXECUTION_ENV the way Lambda does, so @sparticuz/chromium takes its Lambda branch with nothing set by hand. It returns the value it saw. * fix(aws-lambda): agree the move of the ffmpeg build workflow into the image workflow * fix(aws-lambda): build the Chrome pack URL from the pin and hand the checked pack to tar in memory |

feat(skills)!: publish seven knowledge skills aligned with Studio and retire the workflow skills (#5651)
* refactor(skills): fold six domain skills into hyperframes and media-use guides
hyperframes-core, -animation, -keyframes, -creative and -studio move to
skills/hyperframes/{core,animation,keyframes,creative,studio}/, and
hyperframes-audio moves to skills/media-use/mix/. Each moved SKILL.md becomes
a frontmatter-free GUIDE.md so installers that scan recursively for SKILL.md
no longer see them as skills; the published list goes from 21 to 15.
Relative links, code paths and skill-name mentions are rewritten to the new
locations, the catalog surfaces, marketplace core-skills list, fallback core
set, module-copy targets and skills-manifest.json follow, and
`hyperframes skills update` now removes the retired skills (RETIRED_SKILLS)
when they are still installed.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* feat(skills): slim the core entries and give media-use a HeyGen and a free path
The four entries every run opens are rewritten to what an agent cannot infer:
hyperframes 21.8 KB to 7.7 KB, hyperframes-cli 24.8 KB to 6.9 KB,
hyperframes-registry 9.9 KB to 4.3 KB, media-use 9.7 KB to 4.9 KB. Detail moved
whole into references (routing close calls and creator edits, CLI pin upgrades,
catalog search tiers, CLI conventions and feedback reports).
- hyperframes: state table, routing, the render contract, a terminal work loop
(check, snapshot, preview before render), the desktop-app hand-off, and a
table of the folded guides.
- media-use: one table of HeyGen versus free local tools per need; HeyGen
sign-in, credits and the CLI's video-agent, avatar, clone, lipsync, translate
and clipping commands; every free path works with no account.
- scripts/check-core-skills.mjs holds entries and descriptions to budget and
checks every taught `npx hyperframes` command and path; runs in lint.
- Core entries are exempt from the formatter: its table padding cost ~1.5 KB
per entry on every run.
- Content tests follow the text to its new home.

* fix(skills): plugin runs skip skills update; media-use explains HeyGen sign-in and TTS setup
The smoke eval showed a presenter request never reaching media-use and the
free voiceover failing on a missing kokoro-onnx; plugin runs also ran the
skills update the plugin rules forbid.

* chore(skills): drop a committed Python bytecode file and ignore bytecode
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* feat(skills): align the entry with the Studio skills and keep the workflows' measured facts
The entry drops routing and the intent interview and carries the contract, the
editable-project rules and the work loop. Studio's format, runtimes, motion,
look and captions references come over for terminal use, frame presets move to
assets/, media-use gains Studio's mixing and local-command references, and
film.md and overlays.md keep what the workflow skills measured.

* feat(skills)!: retire the workflow skills and folded guides; publish seven knowledge skills
The skill pack now publishes exactly seven skills - hyperframes,
hyperframes-cli, hyperframes-registry, media-use, figma, slideshow and
remotion-to-hyperframes - carrying knowledge, not process. The eight
workflow skills, the folded domain guides and the routing/interview
references are deleted; their measured facts already live in the
hyperframes references (format, runtimes, motion, look, captions, film,
overlays) and media-use's mixing reference.
- bake-basemap.mjs and locate.mjs move to skills/hyperframes/scripts/
(bake-basemap gains --help); extract-audio-data.py moves to
media-use/audio/scripts/ for the caption motion reference.
- skills update: the eight workflows join RETIRED_SKILLS so existing
installs prune them (by lock attribution only, since their names are
generic); naming a retired skill reports where its knowledge went and
succeeds instead of failing as unknown.
- Capture prompts point at the hyperframes skill's references/film.md;
the live-map warning names the new bake-basemap path.
- Content tests that pinned knowledge are retargeted to the kept
references; tests of deleted workflows, scripts and process go.
- Catalog surfaces, templates and docs describe the seven skills.

* fix(skills): resolve the local.md captions link and allow capture's output files in citations
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): regenerate the skills manifest from tracked files only
The committed media-use hash included an ignored __pycache__ bytecode file present
in the local checkout, so CI's clean checkout hashed differently.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(docs): restore generated catalog pages and docs navigation to main
Catalog PRs commit item sources only; CI regenerates the pages from the edited
registry sources. docs/docs.json is catalog navigation, so its Workflows group
rename is left for a non-catalog PR.

* build(cli): raise the CLI size budget for the skill references it bundles
The CLI bundles skills/hyperframes, which now carries the folded domain guides and
frame presets (155 KB to 1.08 MB in git). Budgets are the CI-measured size plus 5%:
packed 7526634, unpacked 22593213.

* test: keep repo-sweep guards meaningful after the workflow skills left
The last shell ffprobe caller and most root index.html examples lived in retired
skills. The shell detector is now pinned on a literal command line, and the
structure-rule sweep needs more than 5 roots (11 remain) rather than 30.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* feat(skills): slim figma, slideshow and remotion to the Studio shape; restore the storyboard board
slideshow 33.5 KB to 4.9, figma 18.2 to 6.2, remotion-to-hyperframes 11.0 to
4.9, each keeping the facts only it holds (the figma motion helpers, verify gate,
storyboard decoding and usage beacons; present and hand-off; the Remotion lint,
SSIM check and API map). The board page format from the storyboard recipe comes
back as hyperframes/references/storyboard.md: the desktop app's Storyboard tab
reads boards/storyboard.html by its frame, title and time classes. The entry and
the init template now say to snapshot the moments an edit changed before
replying, which the terminal eval found skipped in 22 of 38 runs.

* fix(skills): manifest without local bytecode; Studio's edit prompt names kept files
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): render when the person asks for the file or for no stops, not only after approval
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): keep the voiceover carve in media-use; presets stage their own fonts
Review follow-ups on #5651:
- carve.mjs and its tests move to skills/media-use/audio/scripts; the audio
docs, mixing.md and two Studio comments point there.
- code-editorial's FRAME.md says to copy its bundled WOFF2s and add the
@font-face blocks, instead of promising the retired build-frame.mjs.
- media-use states the host rule before the HeyGen sign-in steps.
- storyboard-format marks transition_in as a note the agent builds itself.
- Two stale citations (creator-editing-recipes.md, sub-compositions.md).

* feat(skills): films that tell a story start from three storylines; maps use real imagery
Opus 5.5 arm D read motion.md and applied it, but its launch film was a
feature list (pain, three feature cards, proof, logo): film.md left story
to the model. And the map case never opened film.md, so it drew Natural
Earth outlines instead of baking satellite tiles.
- references/story.md: the generic half of Studio's moment-film story and
craft (one thing, three storylines with world and device, the hook,
beats, worlds, copy, brand, tells of a generated film). The person picks
a storyline, or the agent takes its recommendation when asked for the
file or for no stops.
- The entry's work loop names the storyline step for films over ~15 s; the
references table routes stories to story.md and maps to film.md.
- film.md points at story.md and gives maps and real places a section.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): story.md follows the entry: no voiceover unless asked
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): bake-basemap starts from a globe and stops waiting out its idle timeout
The Opus 5.5 map run spent 13 of its 38 minutes on parallel bakes that
stalled and 15 more recording 300 frames, after rewriting the script because
it could only start on a flat map.
- PROJECTION=globe with a seeded starfield and atmosphere, and FROM/PAN to
turn the globe to CENTER before the dive.
- Each frame polls for loaded tiles instead of waiting for an "idle" event
that had often already fired: 30 frames went from 198-219 s to 10-13 s
locally with byte-identical frames.
- Progress prints seconds a frame and minutes left; film.md shows the globe
call and says to run one bake at a time.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): render in the foreground; wait on a detached render's log, never pgrep -f
Both Opus 5.5 explainer runs started a detached render, then waited with
`until ! pgrep -f "hyperframes render"`, which matches its own loop: each
render took 88-117 s and the wait sat for the tool's full 10 minutes.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* feat(skills): route each kind of film; storylines carry look and sound; add review and sound
The entry routes by request (launch, explainer, music, data, vertical, 3D,
character) to a self-contained file under references/types/, and a film
over ~15 s now gets music and sounds on its visible actions unless the
person asked for silence. Each storyline names its look and its sound, so
picking one picks both; STORYBOARD.md frames carry `reads` and `sound`.
review.md is the whole-film pass: the check warnings, the review sheets,
seven questions to look for, P0/P1/P2 notes and REVIEW.md. motion.md gains
eases by role, six title entrances, a reading-time rule and nine measured
transitions; look.md a design plan before the first scene, with presets
kept for decks and named picks. story.md adds the second default that
generated design falls into, with what to do instead.
The blank template and format.md no longer teach the fade-and-slide-up
entrance on a dark canvas.

* feat(cli): check warns on unread lines, dead stretches, small type, empty frame 0 and silence
A coding agent cannot watch its film, so check now measures what a viewer
notices over time. A new `craft` section holds warnings only (exit 0
unless --strict), sampled on the dense 8 fps grid the overlap pass
already seeks, skipped for --range checks:
- line_unread: a reading-size line (>= 30 px tall at 1080) on screen
under 0.4 s for 1-2 words, else under 3/4 of 0.5 s + 0.3 s a word;
the film's last line needs 2 s. Short lines are re-measured between
samples to ~0.01 s before judging. Captions-track and
data-layout-ignore text are exempt.
- dead_stretch: more than 3 s where the keepsMoving liveness signature
does not change, outside the final 3 s and any data-hold element;
quiet when sweep_static fires or a whole-composition keepsMoving
assertion owns the limit.
- text_below_floor: text under 2.6% of the short side (28 px on 1080)
held 0.5 s, one finding per file listing every element.
- first_frame_empty: frame 0 paints only the background.
- film_silent: over 15 s with no unmuted audio or audible video.
Each message names the fix and the skill reference to read. keepsMoving
now also leaves the film's last 3 s (a still end card) out of its
static runs, so the two agree.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* feat(cli): snapshot --review captures a beat sheet, seam strips and a phone sheet
snapshot --review picks the frames that show a film over time instead of
evenly spaced ones, in the same single browser session:
- review-beats.jpg: one settled frame per scene at its start + 0.3 s,
plus one per timed data-beat="name" element, labelled time and id.
Scenes are the composition's top-level timed clips and sub-composition
hosts, read like `timeline` reads rows (captions and audio excluded)
and timed by the runtime's start resolver over the live page.
- review-seam-NN.jpg: frames at -0.2, -0.1, 0, +0.1, +0.2 s around
every cut (each scene start, and any scene end no scene starts at).
- review-phone.jpg: the beat frames at 360 px wide.
--composition scopes the review to one sub-composition; with fewer than
two scenes the beats spread evenly and a note says so. snapshot also
gains --json: one envelope with every frame's path and time and, under
--review, the scenes, beats and seams behind the sheets; progress moves
to stderr.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(cli): craft warnings stay out of --strict; a hold gets a real next action, not a caret
Craft findings (unread lines, dead stretches, small type, an empty first
frame, silence) are judgment calls a film may break on purpose, so
--strict keeps gating defects only. The check reference no longer
suggests a blinking caret to keep a still frame moving.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(cli): review spreads beats when every scene starts together; map credits skip the type floor
A map film whose basemap and overlay both start at 0 s got one beat
frame; the even spread now keys on distinct scene starts. film.md tells
agents to mark the imagery credit data-layout-ignore and back it, since
the new type floor flagged it on the first real run.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(cli): review frames each scene at its middle too, not only 0.3 s in
On the first real explainer, 0.3 s into a scene showed a bare colour
field before its title entered. Each scene longer than about a second
and a half now adds a frame at its middle, so the sheet shows what the
scene builds.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* feat(skills): a film is built from a numeric SPEC.md, with defaults banned by name and a look test
Studied in full: flxrnc's Motion Lab (vague vs directed prompt), 0xMovez's
course, EianLu's riso skill, agentchengfeng's style samples and the two
Opus 5.5 guides. Their common point: adjectives are where the default look
lives, so the agent now writes SPEC.md before any scene (GOAL, OUTPUT,
TIME, LOOK, MOTION, SHOTS, BANNED, QA), with a number for every adjective.
spec.md bans the defaults by name, unless the brand or reference uses
them (a dark void with small things floating, glow and particles, the
cream-serif-mono-label look, fade-and-slide-up, corner brackets), and
grows that list after the first render. Each storyline gets a 3 s test of
its hero shot before the pick; a look is written as the rules of one
medium. Composition numbers: the hero fills 40% of the frame, one hero
move per shot, the shot's information in within 2.5 s then a held poster.
motion.md adds springs by damping ratio, shorter exits, overlap, stagger
and the beat grid; review.md reviews as a harsh director and grows BANNED;
vertical.md takes the riso skill's measured safe band; explainer.md the
shapes of information.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): story before look; every object reads as itself; posters only for info cards
The first spec-driven C02 swapped the dark default for a flat Swiss
poster, and the story went with it: two black bars nobody read as mirrors,
slogans instead of cause and effect, a storyline picked for its picture.
The spec now serves the story: a storyline is picked for the story a
stranger would follow, the look test asks first whether a stranger
understands what they see, and SPEC.md gains an OBJECTS line giving each
thing the material and details that make it read without a label. The
2.5 s held-poster rule is limited to information cards; in a story film
every shot causes the next. Explainers start from a person or situation
the viewer knows. Review names every object as a stranger would and
treats one that needs explaining as a P0.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(skills): storylines are three films in words, each with a device and a form
The three storylines are pitched as text and the person picks from them;
nothing is built for a storyline before the pick, so the 3 s hero-shot
look test is gone. Ideas pair a device with a form, five or more first,
keeping the three that differ most, and the one stop states the rest in
an assumption line that names every paid item beside its free option.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* ci: list main's new embedded-captions hf-cli test among the retired workflow files
The merge with main removed it with the rest of the retired skill, and the
deletion guard rejects any removal it has not been told about.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(core): keep the audio preset comment within core's size budget
The comment's new citation to media-use's mixing reference made the published
package 14 bytes larger than its budget, which sits at main's exact size.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(cli): craft keeps its own 8 fps grid; comments back within the checks
Review on #5651 found that the merge moved craft onto the overlap pass's
times, which main caps at 180, so a brief line in a long film fell between
samples and line_unread missed it. Craft now builds its own grid at 8 fps up to
600 samples, as before the merge, and a 60 s film with a line shown for 0.2 s
pins it.
The Comments check passes again: REVIEW.md and STORYLINES.md join the files a
skill writes into a project, the comment lines this branch added come back
under each file's share at the merge-base, and the audio preset comment drops
a word the check reads as history.

feat(cli): cloud render uploads heavy media as HeyGen assets (#5931)
* feat(cli): cloud render uploads heavy media as HeyGen assets Media of 5 MB or more leaves the project zip: it uploads through the direct-upload flow as a HeyGen asset and the zip's HTML and CSS point at the asset URL. Uploads are cached by content hash and re-checked before reuse. Media the asset API refuses or caps is re-encoded at visually lossless quality first. The zip must end under 200 MB or the command stops and names the largest files left. * feat(cli): cloud render offloads GIFs, still images and script-referenced media Animated GIFs in the entry composition go through the renderer's own GIF preparation and upload as the resulting video. Still AVIF, GIF, BMP and TIFF images convert to PNG. Plain string literals in scripts and JSON that name offloaded media point at the asset URL. ffprobe calls end their options with "--", and two comment lines are trimmed for the ratchet. * feat(cli): cloud render uploads only the parts of long media a composition plays A video or audio file that has to be re-encoded is cut to the union of the windows its clips play, with half a second of margin on the source's frame grid, and the staged composition's media starts shift to match. Clips in sub-compositions, looping clips, speed ramps and files a script names keep the full file. * fix(cli): cloud render no longer decodes media files as text when rewriting references * fix(cli): cloud render keeps media chosen at render time and encodes the staged bytes Only media a reference points at is offloaded, so a file picked through --variables or built by a script stays in the zip. Variable-bound clips and clips with a media fragment keep their full length. Entry GIFs resolve the way the renderer rebases a nested entry and are prepared only from 5 MB, and every encode reads the staged bytes its cache key hashes. Query strings and media fragments survive the rewrite, a null cache file reads as empty, and the docs say asset URLs are public and unsigned. * fix(cli): cloud render comments cite only what this repo holds * fix(cli): cloud render handles media over 2 GiB and explains a too-large upload Media of 5 MB or more stays on disk until it is used: it is hashed and uploaded as a stream, and a file edited after staging stops the run instead of caching the wrong upload. Files left in the zip are sized before any is read, so a 4 GB file reports "too large" instead of crashing. The asset API rejects an over-limit upload as invalid_parameter with "File too large"; that now gets the dry-run hint instead of the --help one. * fix(cli): cloud render checks and reads each staged file through one handle Staging, the on-disk staged read and the re-encoded output read each opened the path twice: once to stat, once to read. A file swapped or edited between the two could be read without the size or change check seeing it. Each now opens once, checks the open file's stat before and after the read, and reads from it. * test(cli): a heavy file a script builds from split strings stays in the cloud render zip * fix(cli): cloud render keeps media scripts may reach and never trims clips scripts retime - An offloaded file keeps its zip copy when script code holds both its stem and extension, so a path joined at runtime still loads. - Entry GIFs are prepared from a private copy checked against the staged file, so the GIF cache never stores a later edit. - No cut when any script can write a clip's timing attributes, dataset, currentTime, playbackRate, src or loop. |

fix(cli): a finished capture exits even when a site's DNS never answers (#5983)
* fix(cli): a finished capture exits even when a site's DNS never answers Capture resolved every page request with the system lookup and gave up after 10 s, but a system lookup cannot be cancelled: the abandoned one kept the process alive until the OS resolver timed out, so a capture that had printed its result could run past the app's 5-minute cap and lose its folder. Resolve through c-ares instead, as hostAnswers does, and cancel it at the same 10 s deadline. * test(cli): a capture lookup that answers must exit right after too Dropping the timer cleanup kept every successful lookup alive 10 s and no test noticed. * fix(cli): capture falls back to the system lookup and exits once its result is out c-ares answers first. When it has no answer, the system lookup (hosts file, OS-only DNS) runs in a child process killed at the 10 s deadline, cached per host, because Node waits for an in-process system lookup even in process.exit. Capture then asks the CLI to exit 100 ms after printing its result, as render does. * fix(cli): capture reads the hosts file first and kills its lookup child on exit The hosts file answers before DNS, as the system lookup does (overrides and 0.0.0.0 blocks keep working). A host whose system answer is cached skips c-ares, a caller that joins a running lookup keeps its own deadline, and a pending lookup child is killed when the CLI exits. * fix(cli): capture's forced exit waits until a slow reader has the whole result The root exit now waits for stdout and stderr to hand over what is already written before it calls process.exit, so a large JSON result on a slow pipe arrives complete. A hostname listed several times in the hosts file now has every address checked, not only the first. * fix(cli): keep process exit in the CLI root and let test fixtures exit The output wait is now a helper that only waits; cli.ts still owns the process.exit. The process-ownership check treats test fixtures like tests, since each one runs as its own process. * chore(cli): run the process-ownership check before every commit A process.exit outside a process root used to pass the local hooks and fail only in CI's Preflight. |

perf(cli): a repeat check starts with the CLI and Chrome already up (#5943)
* fix(cli): the browser the CLI launches exits with it, even on kill -9 * fix(build): the root build runs on Windows * perf(cli): a repeat check runs in a process that already has the CLI and Chrome up * fix(cli): a warm check delivers all its output before it exits * fix(cli): the warm check only talks to a server that proves it is the user's The warm socket now lives in a private, owner-verified directory (XDG_RUNTIME_DIR, ~/.cache or LOCALAPPDATA) next to a 0600 token. Client and server prove the token to each other over fresh nonces before any request is sent, the request carries an HMAC of the environment instead of the environment itself, and frames are capped. * fix(cli): a warm check prints its stdout even after something went to stderr The client stopped writing frames once any frame had been written, so a check that printed a notice to stderr first lost its JSON report. * test(cli): list the warm-check client fixture as a fallow entry instead of an inline ignore * fix(cli): a check started while a warm one is busy runs cold at once on Windows The warm server stopped listening when it accepted a client. On Windows the pipe name stays alive through the served connection, so a second client's connect saw a busy pipe and waited 30 s for a free instance before running cold. It now keeps listening while serving (accept already declines anyone else) and stops when the served check finishes. * test(cli): the orphan test reads the check's own Chrome and watchdog instead of racing a poll On Windows each process listing is a PowerShell call of about a second, so a check that finishes quickly could start and close Chrome between two polls, and the test failed its own 'Chrome was seen' precondition. A fixture now records the Chrome tree and the watchdog from inside the check when its first page opens. |

perf(engine): re-renders reuse the extracted frames of remote videos (#5408)
* perf(engine): re-renders reuse the extracted frames of remote videos A remote video is downloaded into the render's own work dir, so its path and mtime are new on every render. The extraction cache keyed on both, so a re-render of a composition with a remote video never hit the cache and ran ffmpeg over the whole clip again. Key a downloaded source on the SHA-256 of its bytes instead. Keys of local sources are unchanged. * fix(engine): key the video copies a render writes itself by content The producer downloads a remote video at compile time and copies it into the render's compiled dir, so the extractor never sees the https src. Key any source inside the compiled dir or the extractor's own output dir by content, and skip the cache for one that cannot be read. * perf(engine): hash a render-written video only when its cache lookup runs Distributed planning copies the whole project into the compiled dir and defers long video extractions, which never look up the cache. Hash render-written sources just before the lookup, once per file, so deferred ranges and repeated sources are not hashed. * fix(engine): cache only downloaded media by content, not distributed project copies A distributed plan copies the whole project into the compiled dir, so keying everything there by content would hash every project video on the planner. Content-key the extractor's own downloads and the dirs the caller names; the producer names its remote media dir. Hashing stops on abort, and a source with no hash skips the cache. * style(engine): keep the extraction cache's comment share at its base * test(engine): pin no hashing with the cache off and the producer's remote-media dir * test(engine): run the cache-off case through the shared render helper |

fix(cli): recognize textual motion in sweep checks (#3707)
* fix(cli): fingerprint textual sweep state * fix(cli): share one motion classifier between sweep guard and liveness The frozen-sweep guard (sweep_static) and keepsMoving liveness (motion_frozen) each owned their own definition of "what counts as motion": the sweep fingerprint in layout-audit.browser.js read nine channels while motion-sample.browser.js compared box + opacity only. They meet in one decision in checkPipeline.ts, so a fixed-width attr() countdown was accepted by the sweep guard and still reported frozen by liveness. Move the classifier into motion-signature.browser.js, injected before both samplers, and make it the single owner: - Per-element channels (box, opacity, font-variation axes, clip-path, direct text, form-control state, ::before/::after content, media pixels) as a reader list so further channels (e.g. SVG dash) plug in. - Liveness consumes the same signature with 2px / 0.08 bucketing; the sweep guard consumes it exact. motion-sample throws at install if the shared script is missing. - Counter state is a composition-level channel over box-generating elements and root ancestors. display:none subtrees generate no boxes and are excluded, and only declarations naming a counter that some painted generated content (::before/::after/::marker on a non-ignored, paintable host) consumes are folded in, so a decoy hidden counter cannot make a frozen composition read as live. - clip-path is a channel, replacing the fingerprint's former reliance on the clipped-away visibility probe, so a wipe over a static box still counts. - data-layout-ignore layers are excluded from the signature but not from the per-selector `visible` bit reported for explicit motion assertions. - Root resolution for the "*" liveness scope now matches the sweep guard and the root element is part of its own signature. Tests: motion-signature.browser.test.ts (happy-dom, per-element fake computed style so ancestor handling comes from the classifier) and motion-signature.browser.chromium.test.ts (real Chromium via puppeteer-core; skips without a system browser) pin every branch: attr() substitution, display:none decoys, named-counter gating, ::marker, zero-box hosts, ancestor counters, textarea/indeterminate, root text, clip-path, ignore layers, and sweep/liveness agreement on the countdown fixture. Co-Authored-By: Miguel Ángel <miguel.sierra@heygen.com> * fix(cli): prune unrendered content from the motion signature and measure asserted scopes The shared motion classifier pruned only display:none subtrees, so text, pseudo content, media pixels, and counter decoys inside skipped content-visibility contents changed the frozen-sweep and liveness signatures although nothing painted. Pruning is now platform-owned where checkVisibility exists (display:none, skipped hidden/auto contents; a display:contents host keeps its painting pseudo-elements), with the computed-style fallback for happy-dom. A content-visibility:hidden host signs its own box, opacity, clip-path, font axes, and widget state, but not its text, pseudo content, control value, or media pixels; hosts where size containment does not apply (non-atomic inline, display:contents, table and internal table boxes, ruby) skip nothing. isVisibleElement regains the checkVisibility floor layout-audit uses on its opacity-floor path, so an asserted selector inside skipped contents reports hidden. The layout-audit opt-out no longer applies to the element passed as the signature root: a keepsMoving scope that is itself data-layout-ignore is measured (an assertion naming an element outranks the opt-out) instead of producing an empty signature that motionAudit reports as a missing selector. Opt-outs inside the scope still apply. motion-sample defers the missing-classifier error to the first call so the driver's evaluate surfaces it instead of an opaque "is not a function" page error; round() is shared. The real-Chromium suite is opt-in on Windows (HYPERFRAMES_BROWSER_TESTS=1): in the shared Windows package lane the runner's Chrome did not launch within the package hookTimeout, and the suite already runs on Linux CI where the system Chrome is found. The launch hook has its own 120s ceiling. Co-Authored-By: Miguel Ángel <miguel.sierra@heygen.com> * fix(cli): prune display:contents in skipped contents; table-cell skips, caption paints A display:contents child of a content-visibility:hidden host has no box of its own, so the platform check could not tell it apart from an ordinary display:contents owner and it stayed a counter consumer: a change of the owner's counter-reset altered the sweep signature although nothing paints. The parent's skipsContents verdict now prunes it; boxed descendants keep being decided by the platform. NOT_CONTAINABLE_DISPLAY had table-cell and table-caption inverted versus Chromium 152, where a table-cell host skips its contents and a table-caption host paints them. Four Chromium pins: the display:contents-in-skipped-contents counter, a table-cell host's own text and pseudo content (frozen), a table-caption host's own text and pseudo content (motion), and a counter reachable only through a skipped host's hidden ::marker / ::after (frozen; also asserts the skipped child is not visible for motion-sample).

fix(studio): a hand drag moves only with its own pointer pressed (#4880)
* fix(studio): a hand drag moves only with its own pointer pressed Chromium re-sends the last known pointer point with no button held after a layout change. The overlay's move handler took those as drag travel, so the element flipped between the pointer and that stale point, and the release committed whichever came last. * test(studio): the edit accuracy grid drops a drag after a buttonless move at the press point Nine pathstray cases: a 180,90 drag whose last move before the release is a buttonless pointermove back at the press point, as Chromium resends after a layout change. Main saves the element where it started; this head saves it where the pointer let go. The frame sampler ignores that untrusted move as pointer position. * fix(studio): keep the drag rule's comment to one line * fix(studio): crop handles and the marquee band also ignore a buttonless move mid-gesture * test(studio): bank the nine stray-move cases in the edit accuracy baseline * test(studio): one crop drag helper, the band's candidate refresh in its own step, and formatting * style(studio): wrap the pointer gesture comment under 120 characters |

feat(cli): add hyperframes clean to find and remove what HyperFrames left on disk (#4701)
* feat(cli): add hyperframes clean to find and remove what HyperFrames left on disk `hyperframes clean` lists leftover render work dirs, debug renders, the history of projects that no longer exist, idle video proxies and extracted video frames, with sizes, and removes them. `--dry-run` removes nothing, `--json` is for agents, `--snapshots` also removes snapshot folders (otherwise listed as reclaimable). It never touches outputs, sources or anything a running render or preview still owns. * docs(cli): say that clean does not search a project's subfolders * fix(cli): clean test compares folder names on Windows and the skills manifest is regenerated * fix(studio-server): the proxy cache sweep removes only files the transcoder named It removed any idle .mp4 or .webm in .transcode-cache, so a user file placed there, or reached through a symlinked cache folder, could go. Proxies are always <sha256>.<ext> and their temp files .tmp-<uuid>-<proxy name>; nothing else is swept. * style(producer): keep a renderDirOwner doc comment within 120 columns |

fix(cli): commands exit right away even when the network or DNS is broken (#4604)
* fix(cli): commands exit without waiting on update checks or telemetry The update and skills checks run in a detached child that refreshes the caches for the next run; the parent only reads the caches. finalizeCli no longer awaits the telemetry flush: the exit handler flushSync() delivers what is queued. The events beacon, feedback and figma error paths stop awaiting flush() too. * fix(cli): retry a failed background check at most once an hour Before starting the background worker, the CLI stamps a per-check attempt time and skips a check it attempted within the hour, so a dead network no longer starts a worker on every command. The stale-pin notice writes onto a fresh read, detached spawns set windowsHide, and a test ties the worker path to its build entry. * fix(cli): a failed-check stamp dated in the future no longer silences update checks |

feat(cli): transcribe with Parakeet on macOS, Linux and Windows after an opt-in install (#4583)
* feat(cli): download Parakeet with models install parakeet and transcribe with it `hyperframes models install parakeet` installs the sherpa-onnx runtime from npm and the Parakeet TDT 0.6B v3 int8 model from Hugging Face, pinned to a revision. Every file is checked against its pinned size and sha256 under a temp name before it is renamed into place. Re-running it is a no-op. On Linux with glibc older than 2.32 it refuses up front. `transcribe --engine auto|parakeet` now prefers that engine when it is installed, then an installed parakeet-mlx runner, then whisper. Audio is cut into about 60 s windows at the quietest 100 ms near each cut, and decoding runs in a child process. If the child cannot load the runtime or crashes, transcribe falls back with one stderr line saying why. The JSON output and transcript.json shape are unchanged. * fix(skills): report the real word count and engine from transcribe fallbacks The media-use transcribe script read `words` from the CLI's transcript, which is a flat array, so its whisper path always reported an undefined word count. The embedded-captions script labelled every CLI transcript whisper.cpp even when `--engine auto` ran Parakeet; it now uses the engine the CLI reports. * fix(cli): pin the sherpa-onnx native package to the runtime's exact version * test(cli): type the sherpa install test doubles * fix(cli): transcribe audio with no speech as 0 words instead of failing Parakeet writes an empty word list for a music bed, a silent intro or a very short clip, and loading it failed with "Unrecognized JSON transcript format". An empty list is now read as a transcript with no words, as whisper's empty output already is. A non-empty list still has to look like words. * fix(cli): re-decode a Parakeet window that skipped the start of its speech At some window lengths the model silently drops the first clause: on a looped speech clip, 4 of 167 lengths between 55 and 60 s, and a 61.91 s window, lost their first 9 words. A window with a token gap of at least 1 s that is as loud as speech is decoded again with 0.5 s of leading silence, and the result with more tokens wins. Clean windows are unchanged. Decoding with 1.5 s of overlap before each cut was measured too and was worse on 573 s of audio (2.62% WER against 0.98%), so it is not used. Empty audio no longer makes a zero-length window, which aborted the decoder. * fix(cli): stop Parakeet on Ctrl-C and name the repair when its install breaks - Ctrl-C during a Parakeet transcribe now stops with exit 130 instead of starting whisper, and a SIGTERM to the CLI also stops its decode child. - Ctrl-C during models install parakeet aborts the download and the npm install, keeps no partial file, and exits 130. A staging dir left by a killed install is swept by the next run. - When Parakeet fails under --engine auto, the warning leads with the Parakeet error and names hyperframes models install parakeet. If the fallback fails too, the Parakeet error is reported rather than whisper_unavailable, so --optional no longer hides a broken install. - An explicit --engine parakeet no longer falls back: it fails with the Parakeet error and the repair command. - The install refuses up front on systems with no native package (naming the six supported ones) and on musl, instead of a raw npm error. - 24-bit and float WAV go through ffmpeg, since sherpa-onnx reads only 16-bit PCM. The decode timeout scales with the audio length. * docs(cli): point Parakeet setup at models install parakeet The transcribe docs and the media-use references named parakeet-mlx as the only way to get Parakeet. They now name hyperframes models install parakeet, and the CLI reference gets a models section. * test(cli): cover the npm cancel signal and decode timeout, and fix a doubled period The Parakeet failure line printed "failed.. To repair" when the decoder's own message ended in a period. Tests now also pin that Ctrl-C reaches the npm install and that the decode timeout scales with the audio length. * fix(cli): report unreadable audio as an input error, not a Parakeet failure Prepare the WAV once before the Parakeet fallback and hand the same file to whisper, so ffmpeg runs once. Ctrl-C while ffmpeg runs now ends as a cancel (exit 130) instead of starting whisper. * fix(cli): recover a clause Parakeet drops after a pause by decoding the gap alone Each loud gap without tokens is decoded on its own with 0.5 s either side, and only its new tokens are spliced in. The padded whole-window retry stays as the fallback. A window with no tokens at all is no longer decoded twice. * perf(cli): size the decode timeout from the WAV header instead of reading the file * docs(cli): say a broken Parakeet install still fails transcribe --optional * fix(cli): treat Ctrl-C during audio preparation as a cancel and drop the partial WAV ffmpeg traps SIGINT and exits 255 rather than dying by the signal, so that status now counts as a cancel unless the timeout fired. A failed or stopped ffmpeg removes the temp WAV it was writing. The decode timeout now sizes a prepared WAV from its file size, so a large header can no longer hide its length. * fix(cli): splice a re-decoded gap by whole words so its neighbours are never doubled The gap decode splits edge words into other tokens than the window decode did. Match neighbours as whole words within 0.3 s of each gap edge, add only whole words that start inside the gap, and decode the gap behind 0.5 s of silence like the padded retry. * fix(cli): count a cancel only when ffmpeg says it received a signal ffmpeg 7 and later also exit 255 when a file is not permitted (EPERM), so exit 255 alone read a permission error as a cancel. ffmpeg's stderr is now captured, a cancel needs its received-signal line, and any other failure reports ffmpeg's last line. The output path is passed to the shared runner explicitly. * fix(cli): keep a spliced gap word that has no leading space The filter dropped such a word; it is now kept and given its word boundary. * refactor(cli): trim three long comments in the Parakeet decoder and installer * fix(cli): repair a Parakeet runtime missing its native binary, and pick Parakeet by language The runtime dir is per platform and arch. Installed now needs the runtime manifest and the native sherpa-onnx.node; a half-installed dir is removed before npm runs, since install() keeps any dir holding the runtime manifest. The decode worker flattens a multi-line loader error onto its prefixed line and stops between windows once orphaned. transcribe opens its cancellation scope before audio prep, so Ctrl-C under --json cleans up. auto uses Parakeet only for its 25 languages and only where the host can run it; --engine parakeet with another language fails. * fix(cli): sweep reused-pid staging, name failed model downloads, keep ffmpeg's cause sweepStaleStaging also removes a staging dir older than 6 hours whose pid is alive, since containers reuse pids. A failed model download names the file, the host and a retry. runFfmpeg keeps ffmpeg's stderr on its error, so transcribe shows "Output file does not contain any stream" for a video without audio, and reads a cancel only from ffmpeg's own signal line. * fix(skills): make media-use --engine whisper run whisper and report the engine that ran The whisper path now passes --engine whisper when asked, or --engine auto, and reads the engine from the CLI's --json line, so a CLI Parakeet run is no longer labelled whisper. Docs state the language rule, the real repair behaviour and the platforms Parakeet runs on. * test(cli): pin that a long Parakeet decoder error is kept whole up to a bound * fix(cli): report a broken Parakeet runtime with the repair instead of skipping it * refactor(cli): name the staging age limit instead of commenting it * fix(skills): let media-use --engine parakeet use the CLI Parakeet when parakeet-mlx is absent * fix(cli): repair a Parakeet runtime that fails to load, and read Ctrl-C after whisper models install parakeet now loads the runtime in a child process, the way the decode worker does, and reinstalls it when that fails, so a missing shared library, a corrupt binary or missing runtime JS is repaired. It reports changed: false when the runtime loads. transcribe keeps its cheap manifest check. After a failure, transcribe lets the event loop turn once before reading the Ctrl-C scope, since a signal that landed during the synchronous whisper fallback is only handled then. * fix(cli): read Ctrl-C from the whisper child, and re-check the Parakeet runtime after a repair A whisper fallback killed by SIGINT or SIGTERM is a cancel (exit 130), the same rule decode and runFfmpeg use; the loop-turn wait is gone. The runtime probe treats a child stopped by Ctrl-C as a cancel and keeps the runtime; a reinstall is probed again and fails with the loader's error if it still does not load. media-use keeps the CLI's last lines, stdout included, when hyperframes transcribe fails. * fix(cli): give the user-stop rule one owner, SIGHUP included, and end a cancelled install at 130 stoppedByCancelSignal in renderCancellation.ts uses the scope's own signal list (SIGINT, SIGTERM, SIGHUP) and is false whenever Node stopped the child (a code, killed, or a spawn error). decode, runFfmpeg, the runtime probe and the whisper fallback all route through it, so a probe killed by SIGHUP keeps the runtime. isWhisperTimeoutError now keys on ETIMEDOUT only, which Node sets on execFileSync's own timeout, so a SIGTERM reaches the cancel rule. A cancelled models install sets exit 130 and returns instead of failing, and the probe says what went wrong (timed out, crashed, no output). * refactor(cli): let the stop-rule helper name carry its meaning |

* ci(studio): gate Studio open and timeline scroll on work counts that only go down Beside the timeline viewport gate's ms budgets, count the work two Studio journeys do and hold each count under a checked-in ceiling in perf-ceilings.json: thumbnail renders, page loads and requests for opening a 12-scene film, and React commits, style recalcs and layouts per scroll tick.

perf(studio): open a large film ready to play in about 4 s instead of 32 s (#4401)
* perf(studio): keep lint off the preview open path The bundler linted every build only to print a StaticGuard warning; a preview bundle now skips it through a staticGuard option, since Studio lints on its own route. That route now lints in the CLI child-process worker the render path already uses, so seconds of parsing no longer stall the preview and every other Studio request on the server event loop. * perf(parsers): parse identical GSAP source once Studio re-requests the parsed animations of unchanged source on every open, and several lint rules parse the same script in one run. A small memo keyed by the script text serves repeats; each caller gets its own copy. * perf(studio): build each preview document once per content version The preview route rebuilt the document for every browser without a cached copy. It now serves one build per ETag from memory, and the CLI keeps the last build on disk salted with its own file, so a restarted server serves the previous document without stale code. * perf(studio): build the opening film's preview while the browser starts The preview server built the document only when the player asked for it, after Studio had booted, so a first open waited about a second of idle server time. The CLI now requests the opening project's preview right after listening, and requests that arrive while a build runs share it instead of starting another. * perf(studio): request the preview document at page load Studio asked for the preview only once the player mounted, about 640 ms into a first open. It now requests it the moment the page loads, and again when the hash names another project, so the build or cache read overlaps Studio's boot. * feat(studio): show the cached frame 0 while the live preview boots Studio covers the live preview with frame 0 as the thumbnail route last rendered it, sized from the image so the stage does not shift, and removes it when the live frame is ready to show. The request is cache-only, so a miss never starts a render on the open path; the missing poster is rendered after the live frame shows, for the next open. * perf(cli): start Studio before the startup lint finishes hyperframes preview linted the whole project before it listened, 4 to 6 s on a large film, and did so in --json mode where the result is discarded. The lint now runs in the CLI worker while Studio starts and prints its summary when done; --json skips it. * perf(studio): render thumbnails from one loaded page, after the preview boots Every thumbnail opened a page and loaded the whole composition to shoot one frame, and the Compositions card asked for one while the live preview was still booting. The server now keeps one loaded page per preview document and seeks it per frame, reloading only when the project changes; card thumbnails wait for the project first ready preview. * perf(studio): parse GSAP animations after the preview boots Studio asked the server to parse the composition animations while the preview was opening; on a fresh server that cold parse ran on the event loop ahead of the preview build. The request now waits for the live preview to boot, or to fail loading, since only keyframes need it. * perf(cli): find orphaned browsers with one process-table read preview ran pgrep three times and then ps once per matching browser, all synchronously before listening: about half a second on a machine running other headless Chrome. One ps listing now finds every orphan in ~20 ms. * perf(studio): keep lint off the boot Opening a project started two lint processes while Studio booted: the terminal's startup lint and Studio's background lint, ~4 s of CPU next to the boot. Studio's background lint now waits until the live preview has booted, and lint processes run at the lowest CPU priority so they only take idle CPU. * perf(studio): open the editing session after the preview boots Opening a project read the composition source and parsed it for the editing session (linkedom plus hf-id assignment) on the main thread while the live preview was booting on the same thread: ~300 ms on a large film. The session now opens once the preview has booted; nothing the first frame shows needs it. * perf(studio): park the editor overlays until the preview boots The overlay frame loop polled preview geometry and off-canvas indicators from the first frame, forcing layout on a preview document that was still loading, on the thread its boot runs on: ~200 ms before the first frame on a large film. The loop now skips its subscribers until the preview has booted, then wakes. * perf(studio): treat the preview as booted once it can play Work deferred until the boot (editing session, lint, overlays, GSAP parse, card thumbnails) started at timeline-ready, which fires before the asset gate, so the editing-session parse ran inside the wait for play. The Player now latches the boot when the preview can show and play, or fails to load. * fix(studio): keep a left project's deferred work out of the one now open Deferred open-time work (source parse, background lint, editing session) waited on one global boot flag, so leaving a project before its preview booted let the next project's boot run the old project's work and write its results. The wait is now per project and resolves false once another project opens. A preview stuck without an error stops deferring that work after 5 s. * perf(cli): let the play page revalidate instead of refetching hyperframes play served the composition, its assets, the player and the runtime with no validator, so every reload refetched everything, the mp4 in full three times. They now carry an ETag and stay no-cache, so unchanged bytes cost a 304 and an edit is still seen. * fix(cli): serve an edited text asset even when its size and mtime match The play page tagged every asset by mtime and size, so a same-size rewrite within one filesystem tick kept the old tag and the browser kept stale bytes. Text assets now get a content-hash tag; media keeps the mtime and size tag Studio already uses. * fix(studio): close idle thumbnail pages so an idle Studio runs no composition Kept-loaded thumbnail pages stayed open for the life of the server, each running a live composition, so an idle Studio cost server CPU and memory that main does not. A page now closes after 10 s unused, and a page is closed only after the frame still running on it finishes. * fix(studio): stop a first open from reloading the preview once per scene file Studio stamped hf-ids into a composition the first time that composition was served, so opening a film of external scenes wrote to index.html and every scene file mid-session. Each write reached Studio as an outside edit and reloaded the preview, which failed for a large film. The server now stamps every composition once before it starts watching the project. * fix(studio): ignore play until the preview can play, so it is never undone Space (and any play() caller) could start playback before the preview frame finished loading. Its load step then paused and rewound to the restore point, so the play was silently lost. play() now waits for timelineReady, the same gate the Play button already uses. * fix(studio): hold play on a composition switch until the new preview loads Readiness was reset only when the project changed. Drilling into another composition kept the old ready flag while the new preview loaded, so Play or Space could start a play that its load step then undid. * refactor(studio): split background lint and thumbnail page reuse into single-purpose steps Keeps the boot wait in the background lint only, moves page lookup and idle close out of withPage, and drops a suppression the startup worker no longer needs. Behaviour unchanged. * chore(cli): declare the render-setup worker as a fallow entry It is spawned by path from cancellableProcess.ts, so it has no import-graph referrer; the entry list is where the repo records that, replacing the per-file ignore removed in the previous commit. * fix(cli): close a thumbnail page whose load fails The page never leaves the promise that loads it, so when the load throws (a WebGPU composition with no adapter, or the navigation timeout on a big film) nothing could close it. * fix(cli): match text assets by exact type and keep Range on them The pattern anchored only its first alternative, and text assets skipped buildRangeResponse, so a ranged request for a stylesheet or SVG got a full 200. * test: open the next project as Studio does, and read the stamped file once The absent-read guard test switched project without beginning its timeline session, so the per-project boot wait held the read. The stamp test checked then read the same file. * test(cli): rewrite the scene file without opening it first Opening the file by path counted as a check before the later read of the same path. * perf(cli): take a thumbnail's version from the cached project signature Each thumbnail walked the project and hashed every text file for its page version; the adapter already caches that signature and clears it from the watcher. An aborted request now also stops before its screenshot. * fix(studio): keep Play off until the preview's load step has run Play could enable before the preview document's load event, from the runtime's timeline message or from the blank page's load step settling on the preview's first message. The load step then paused and rewound the preview, so a Play pressed in between did nothing; a film with large images loads late enough for this to hit a cold open. Readiness now waits for the document's load step, whichever path asks for it. * refactor(studio): move the preview poster's state into usePreviewPoster NLEPreview.tsx passed the 600-line limit once main grew it; the poster's state and callbacks belong beside PreviewPoster. No behaviour change. * fix(cli): take an earlier thumbnail on a fresh page A composition need not draw the same frame when seeked back, so a kept page that had shown 20 s drew a different 10 s thumbnail than a fresh load. A kept page now only seeks forward, as a render does; an earlier time loads a fresh page. * perf(cli): close a kept thumbnail page a second after its last frame Held for 10 s, the page went on running its composition after the open's thumbnail burst, about 5 % of a core in the thumbnail browser while Studio sat idle. A burst's requests arrive back to back, so it still loads the page once. * fix(studio): count the preview as booted at its first frame The boot waited for every video and audio in the preview to finish buffering, which on a project with media took until the 5 s fallback. The thumbnails, editing session and lint that wait for the boot then started seconds late and kept an idle Studio busy. They now start once the first frame is up; media finishes buffering alongside. * perf(studio): render one thumbnail per composition for its card and clip A composition's sidebar card asked for its frame at 3.00 s and its timeline clip for the clip's midpoint, so opening a project rendered every scene twice. The clip now asks for the card's frame (the midpoint still, for compositions under 3 s), and the thumbnail cache serves both from one render: 20 scene renders drop to 12 on a 12-scene project. * chore: keep each changed file's comment share at or under main's The comment ratchet counts the comment lines this branch added. Each is cut, or kept as one line where it states an invariant (the GSAP parse cache returns copies; the boot starts waiting work at the first frame). The orphan-cleanup docblock is condensed and now names the process-table read it uses instead of the pgrep scan it replaced. No code line changed. * fix(studio): keep a 3 s clip off its end frame and give card and clip one encoded URL A composition exactly 3 s long asked for its thumbnail at 3.00 s, its end instant, which after a fade-out is an empty frame; compositions of 3 s or less now use their midpoint. The card built its thumbnail URL from the raw path while the clip encoded it, so names with & + [ or % asked for two different URLs, and a % in the name made the card's request fail on the server; both now encode. The readiness comment says the boot latches at the first frame, as it has since the boot moved. * fix(studio): encode the card's live preview URL too, and document the bundler's static guard The card's hover preview built its URL from the raw composition path, so a % in the file name made the preview route fail to decode it. The card now builds its composition URL in one place, encoded, for both its thumbnail and its hover preview. The static-guard bundle option keeps a one-line doc (its default and what it warns about); a neighbouring docblock is rewrapped to keep the comment share. * test(cli): mock studio-server once so the signature spy and the history hook both apply The main merge brought a second vi.mock of @hyperframes/studio-server into studioServer.test.ts; the later one replaced the first, so createProjectSignature was no longer a spy and the cached signature test read .mock of undefined. One mock now carries both overrides. |

Export the verb mapping and inject command dispatch for direct coverage. Keep missing-copy diagnostics separate from drift reads. |

feat(studio): all panels move onto the dockable, persisted layout (#4192)
* feat(studio): every Studio panel is a dock panel and the shell moves onto it
EditorShell, App.tsx, the left and right panel columns, and the
inspector hooks now render through Dock.Panel instead of the old
fixed-width sidebars and split-pane inspector. usePanelLayout becomes
a thin facade over the dock store; fitPanels, the resize divider and
the split-inspector hook are dead and removed.
* refactor(studio): drop dead inspector flags and stale fallow entries after dock migration
Collapse inspectorButtonActive into inspectorPanelActive, remove unread
layers/design active fields, un-export unused prop types, flatten a nested
ternary, and point fallow ignores at the renamed/deleted files.
* fix(studio): keep right-panel behaviours the dock migration dropped
Block params dismiss on selection or when Design is hidden, the slideshow
panel can be closed, the selection outline follows the inspector intent,
caption editing focuses Design, and a URL slideshow tab opens once the
panel exists.
* refactor(studio): name the inspector-open state once in the header
* fix(studio): right-panel behaviours survive selection, restore and reopen after the dock migration
Block params stay open over an element that was already selected, caption mode wins over block params, the slideshow panel waits for the dock, the Renders tab title survives a reopen, each side column remembers the tab it last showed, tab switches are reported only when the tab changes, and the e2e thumbnail selector follows the dock.
* docs(studio): describe the dock layout and point comments at the renamed right panels
* fix(studio): block params survive a preview reload of the selected element, and panel titles are covered
The dismissal compares the selected element by its target key instead of object identity, because a preview reload rebuilds the selection for the same element. A closed and reopened panel keeps its custom title, with a test, and the e2e selector is formatted.
* fix(studio): block params leave with any other tab pick, and a restored slideshow placement survives loading
Block params are now dismissed by the tab setter the way their old tab was, including a re-pick of the same element, instead of by comparing selections. The slideshow panel is only closed after a file that was a slideshow stops being one, so a restored layout is not discarded while the file loads.
* refactor(studio): drop the duplicate inspector-open computation
The rebase onto main left two identical inspectorButtonActive/inspectorOpen
constants after a conflict resolution; only the first was still referenced.
* chore(studio): allow the dock migration deletions in the guard
StudioLeftSidebar.tsx, LeftSidebar.tsx and its storage test,
TimelineResizeDivider.tsx, useInspectorSplitResize.ts and fitPanels
are replaced by the dock; the CI deletion guard needs each named
with its reason.
* style(studio): oxfmt the deletion-guard entries
* fix(studio): rename Timeline's aria-label so it does not collide with its dock panel wrapper
Every dock panel wrapper now carries aria-label=<title>, matching the "Timeline"
title for the timeline panel. Timeline.tsx also set aria-label="Timeline" on its
own content div, so `document.querySelector('[aria-label=\"Timeline\"]')` found
the dock wrapper first and the timeline viewport gate CI check timed out waiting
for an attribute the real content div actually carried. Renamed to "Timeline
track view" and updated every consumer: the production diagnostics selector,
its tests, and the e2e viewport-gate script.
* fix(studio): restore inspectorButtonActive as a real prop after a rebase regression
Rebasing PR2 onto main replayed an older local commit whose diff did not
textually overlap main's newer inspectorButtonActive prop, so git applied
it with no conflict marker and silently reverted the header to computing
the value itself instead of receiving it. StudioHeader.dom.test.tsx already
asserts the prop is respected; restoring it makes that test meaningful
again. App.tsx now computes it once (panelLayout.rightCollapsed is already
the dock's effective collapse state, no separate railed-by-width case) and
passes it down.
* chore(studio): wrap a long doc comment in useRightPanelIntents

feat(catalog): add the seven 3D-motion pieces as installable registry blocks (#4056)
* feat(catalog): add the seven 3D-motion pieces as installable registry blocks Each piece ships as a registry block with a CDN poster and preview, a live catalog detail page and its source. Scripts travel inside the catalog payload (shared vendor libraries fetched once, item scripts inline, the one HDR as a data URI) because the docs host only serves fonts, images and JSON. NO_ESSAY_COMMENTS_OK: the long comment blocks are in vendored libraries and the ported frost source under registry/blocks, not hand-written here. HF_MAX_NONLFS_KB=6000: four hosted texture PNGs under docs/public/catalog/items are runtime assets the docs host must serve as files. fallow skipped locally: it audits against origin/main and this branch is stacked on an older main. * chore(catalog): regenerate gallery data and nav after rebasing onto main * fix(catalog): read the install manifest through the bounded project reader * fix(catalog): a script the inliner missed fails the payload instead of shipping a dead URL * refactor(catalog): the leftover-script check reuses the reference finder * fix(catalog): frost and glass textures load from the CDN and the iteration presets are gone * chore(catalog): regenerate the frost and glass payloads and nav * fix(catalog): frost and glass textures are hosted through the registry url field, not hardcoded * chore(catalog): regenerate the frost and glass payloads against the hosted texture URLs * fix(catalog): the hosted-reference rewrite refuses a bare name it cannot safely replace * ci(catalog): verify changed catalog payloads in headless Chrome and check the docs catalog * feat(catalog): every item page follows the shared layout with a Tune panel and tabs * fix(catalog): let the texture-mask item host its masks so its tile plays live * chore(catalog): regenerate item pages, gallery data and the texture-mask payload * chore(catalog): regenerate item pages after merging main * fix(catalog): declared-only variables get the Tune panel, Code and Docs tabs capped * feat(catalog): give the blend-difference caption a demo scene so its tile plays live * chore(catalog): live payload for the blend-difference caption * perf(catalog): heavy 3d pieces compile and draw before ready, not on the first visible frame * feat(catalog): the avatar promo card hosts its videos, audio and fonts on the CDN * feat(catalog): the avatar promo card tile plays live from its CDN-hosted media * chore(catalog): the avatar promo card plays live, no allowlist left * chore(catalog): shorten two comment blocks * chore(catalog): trim first-party comment blocks to the comment-check limits * chore(catalog): shorten two frost source comments * fix(catalog): the Docs tab renders as prose again, and the detail page honours reduced motion Frame-mode pages carry no prose wrapper, and the detail component sat inside not-prose, so the Docs slot's headings, paragraphs, links and lists had no styling at all. The slots now carry their own prose classes and the chrome around them keeps not-prose. The recorded clip also gets the reduced-motion guard the docs-snippet check requires, and the generator reads stability from the source metadata type so the scripts typecheck passes. * fix(catalog): docs-tab paragraphs render as blocks Mintlify emits paragraphs as inline spans, so two paragraphs in the Docs slot ran together. * fix(ci): drop the duplicate docs_catalog job output git's line-based auto-merge silently duplicated the outputs key when main and this branch each added it on non-adjacent lines during the rebase; oxfmt's yaml parser rejects the repeated map key. * fix(catalog): close four CodeQL alerts in the frost source * chore(catalog): allowlist the avatar-promo-card CDN asset deletions, format sync-docs-catalog check-no-main-deletions.mjs was rejecting 11 local mp4/font files this branch already deleted in favor of CDN hosting; scripts/sync-docs-catalog.mjs had one line over the 100-col print width from an earlier edit in this branch. * fix(catalog): detail tabs use docs prose spacing, Install first; previews skip no-WebGPU runners * fix(catalog): the docs tab scrolls with the page instead of a capped inner box * refactor(catalog): split the payload asset and verify scripts into single-purpose helpers * refactor(catalog): split the preview generator into single-purpose helpers * ci(catalog): fail when the committed catalog differs from generator output The docs host serves the committed catalog and nothing regenerates it, so a stale copy shipped silently. The catalog payloads job now generates into a temp dir and compares it with the committed tree. * chore(catalog): regenerate docs/public/catalog with the refactored scripts One full regeneration from an empty output tree with the current scripts. The tree grows from 58.4 MB to 65.1 MB. Two hosted assets are about 2 MB each (an avatar png and a wav); the same bytes are already committed under assets/, so HF_MAX_NONLFS_KB is raised for this commit only. * fix(catalog): run the catalog script tests under the runner they are written for The rebase put three node:test files in the vitest half of test:scripts, where they report "No test suite found". They now sit in the node --test list. * fix(catalog): a WebGPU item without an adapter shows its recorded clip and says why * ci(catalog): the drift check runs from a committed fetch mirror with no network Generation now serves every font and CDN script fetch from scripts/catalog-fetch-mirror and fails when a fetch is not in it, even if the caller swallowed the error. CATALOG_FETCH_MIRROR=record refreshes the mirror from the live network. The docs_catalog filter also watches packages/core, packages/producer and the mirror, and the 13 re-hashed font files are listed in ALLOWED_DELETIONS. * chore(catalog): clean up the temp font cache and sort the mirror index without a locale * fix(catalog): hide Tune when the clip stands in, time out the adapter request, share one check * fix(catalog): the adapter probe survives a sync throw and a hang; test the clip guard * fix(catalog): keep the adapter probe inside the component, Mintlify evaluates only exports * fix(catalog): run the detail and page generator tests in CI; no Tune flash while probing WebGPU * docs(catalog): credit vendored libraries and make each SKILL.md list what the block installs CREDITS.md names every vendored dependency with its upstream and licence, and flags the two leaf textures whose origin is still to be confirmed. Each SKILL.md Files table now comes from the block manifest and its install and render paths point at compositions/<name>/. A test checks that every path a SKILL.md names is a manifest file that exists. * fix(catalog): a declared WebGPU item passes verify by its manifest tag, not by console wording verify-catalog-payloads forgave a missing adapter only by matching the markup and the message, which library-reported errors and widgets never satisfy. The webgpu tag in the item manifest is now the owner: a tagged item ignores its page and console errors, an untagged one gets no forgiveness, and a marker payload with no html is listed instead of crashing the run. * docs(catalog): correct the credits per block and guard the mount and render paths CREDITS.md states the three.js version and vendored-or-CDN status per block, adds d3-delaunay, Clipper on the CDN and the Google Fonts loads, and lists every texture with no known origin. The SKILL.md test now also checks the mount and render paths against the manifest composition. * test(catalog): read each block manifest once in the SKILL.md file test The two checks shared a copied manifest read, which fallow flagged as a clone with a high score. * fix(catalog): commit the hosted item files a gitignore rule kept out, and check git not the disk The compositions/ and *-ad/ ignore rules matched folder names under docs/public/catalog/items, so 33 hosted fonts, textures and marks were generated but never committed and would 404 on the docs host. The rules now have a negation for that tree and the files are added. The drift check read the checkout, where git-ignored files still exist, so it passed locally and failed only in CI. It now unpacks HEAD with git archive and compares that. * fix(catalog): a tile keeps its poster until the composition has painted * fix(catalog): a tagged WebGPU item forgives only the adapter-absent error, and test the wiring The manifest webgpu tag now decides whether an item may lack an adapter, and the error wording decides which lines are that absence. Any other page or console error on the item, and every failed request, still fails. The per-item decision is one exported function the tests drive, marker payloads are parsed by a tested helper, and the SKILL.md variable counts are checked against their tables (cuboid-carousel said forty-nine for forty). * fix(catalog): the pinned group's posters load eagerly at high priority * fix(catalog): type the tile reveal test so the scripts typecheck passes * fix(catalog): stop the adapter signature matching an unrelated failed adapter request failed to request .*adapter also matched errors about other adapters. It now matches only a request for the WebGPU adapter, so a tagged item cannot hide an unrelated failure behind it. * test(catalog): a tagged item still fails on an error about some other adapter * feat(catalog): the install command sits above the preview, as on the live catalog * fix(catalog): find the install slot through Mintlify's child wrapper * fix(docs): catalog copy buttons keep their size when the label swaps to Copied * refactor(docs): name the shown copy label once in the catalog copy button * fix(docs): primary catalog button keeps a readable label on hover and after copy * fix(docs): inset the catalog tab strip and tab content to match the boxed panels |

feat(studio): shared Button, IconButton, Tooltip and Tabs primitives (#3622)
* feat(studio): shared Button, IconButton, Tooltip and Tabs primitives Four primitives that consume design tokens only, plus the configured class merger they all share. - ui/cn.ts: one `cn` instance whose config knows the two class families theme.css invents, the `text-step-*` type scale and the `ctl` control heights, so a caller's class replaces a primitive's instead of stacking with it and letting stylesheet order decide. - Button and IconButton: native buttons on the three control heights, the radius scale, the semantic palette and the motion tokens. Four classes that resolved to nothing (rounded-button, shadow-btn-primary, bg-accent-red, ease-standard) are gone, which is why the Renders Export now has a radius. - Tooltip: Base UI's tooltip, so the portal, the viewport flip and the collision shift stop being hand-rolled. role="tooltip", the id wiring and aria-describedby stay explicit here because the library does not add them. - Tabs: Base UI's tabs, with roving tabindex, arrow keys, Home and End, and a data-tab-id the sidebar's focus restore looks up. Every interactive look is also reachable through a data-preview-state attribute that CSS alone reads, so a gallery can show hover, active and focus without a pointer. A test pairs the two lists in both directions. The class-resolution test compiles Studio's real stylesheet with every class the primitives emit and fails on any that produces no selector. Tailwind treats an undefined class as silence; that silence is what let four dead classes sit in this file. * feat(studio): export Button, IconButton, Tabs and Tooltip from the package root * docs(studio): trim comment blocks to pass the no-essay-comments gate * refactor(studio): use native CSS.escape in the button class-resolution test * refactor(studio): share the ui test mount helper and flatten the Button leading slot * fix(studio): keep the tooltip open on a disabled control * fix(studio): give the tooltip trigger no layout box and anchor to the child * fix(studio): anchor the tooltip through a ref so it adds no render * fix(studio): button children lay out with the consumer gap * test(studio): keep the no-icon label and shortcut layout assertion from the standalone fix * docs(studio): shorten the Tooltip header comment to fit the comment gate * test(studio): the Button vacuity guard names tokens that stay undefined |

feat(catalog): browse the catalog as a live grid, not a static index (#4051)
* feat(catalog): browse the catalog as a live grid, not a static index
The Catalog overview page now mounts a browse grid (posters, tags,
per-category rows, expandable sections) generated over the existing
~380 registry items, instead of one static hero video plus two links.
docs/snippets/catalog-gallery.jsx and docs/catalog-gallery.css are
ported from a reference implementation of this same UX; the CSS keeps
its original comments as-is (NO_ESSAY_COMMENTS_OK: vendored file).
scripts/sync-docs-catalog.mjs and build-docs-gallery-nav.mjs are new,
generating the gallery's data and the Catalog tab's nav directly from
this repo's registry/*/registry-item.json and docs.json, so no sparse
clone or snapshot of another project is needed. scripts/check-docs-catalog.mjs
proves every catalog page from before this change still exists, on
disk and in the sidebar, with an identical page list.
No catalog page or snippet is removed; the previous overview content
(catalog-overview-player.jsx) is unused on this page but stays in the
repo.
* refactor(catalog): share the docs-catalog helpers across the sync scripts
Three independent adversarial reviews (reuse, quality, efficiency) all
converged on the same shape: sync-docs-catalog.mjs, build-docs-gallery-nav.mjs
and check-docs-catalog.mjs each hand-wrote the same docs-root resolution,
the same catalog-gallery-data.mdx parse, and the same Catalog-tab lookup.
Extracted into scripts/docs-catalog-shared.mjs.
sync-docs-catalog.mjs also ran build-docs-gallery-nav.mjs as a dynamic
import purely for its side effect, forcing a same-process re-read and
re-parse of the data file it had just written. build-docs-gallery-nav.mjs
now exports buildNav(docs), called directly with the path already
resolved; its CLI entry is guarded for standalone use.
slug() dropped the /^-+|-+$/ trim in favor of the character-scan trim
packages/core/src/tokenSlug.ts already uses for the same reason (CodeQL
flags that regex as polynomial ReDoS, js/polynomial-redos); not imported
directly since tokenSlug.ts is compiled TS with a different domain
(CSS variable naming) and no existing scripts/*.mjs imports packages/core
source at plain node runtime.
Fixed one bug found while re-verifying after the refactor: the recursive
nav walk wasn't idempotent against its own generated output — re-running
sync-docs-catalog.mjs a second time saw the "Catalog" wrapper buildNav()
adds and misattributed every flat, single-section group under it, 9
groups collapsing to 7. walk() now treats "Catalog" as transparent, the
same way it already treated "Overview". Verified: three consecutive runs
from a fresh origin/main checkout now produce identical 9 groups / 400
items each time, and check-docs-catalog.mjs still passes.
* chore(catalog): scrub an internal decision code from a code comment
* fix(catalog): stop losing a section's label when its nav is flattened
An independent adversarial review found real data loss: build-docs-gallery-nav.mjs
collapsed a group with exactly one section into a flat page list (a clean sidebar
for the common case), but sync-docs-catalog.mjs's walk() derives an item's section
from nav depth, so a second sync run over that flattened nav could no longer
recover the section name and silently fell back to the group's own label. Data &
charts / Data was the one real casualty in this catalog; Carousels and Blocks
happened to already have a section named the same as their group, so the loss
was invisible there.
Fix: only flatten when the section label equals the group label, so nothing
non-recoverable is thrown away. Verified with a deliberate mutation (reverted the
condition, reproduced the exact bug from a clean origin/main checkout, confirmed
the new check-docs-catalog.mjs assertion goes red, then restored the fix and
confirmed 3 consecutive runs produce identical, correct section labels).
check-docs-catalog.mjs now cross-checks every item's section against the nav
itself (not just its href), closing the gap the review found: the old check only
proved the page list matched, never that section identity survived a re-sync.
Also deletes docs/snippets/catalog-overview-player.jsx: unreferenced anywhere in
the repo now that catalog/index.mdx mounts CatalogGallery instead (confirmed with
a repo-wide grep before removing).
* chore(catalog): allowlist the deliberate catalog-overview-player.jsx deletion
* feat(catalog): live-hover preview, fuller sidebar, landing order
Three product asks against the open PR's Mintlify preview, plus one
review finding:
- Sidebar: every top-level Catalog group now defaults to expanded, so
the column shows real content instead of nine collapsed rows over
an empty column. Subsections stay collapsed one level down, the
same depth the reference site itself uses.
- Landing order: Carousels moves to first position (3D motion, not
yet in this repo's registry, will sort first once a separate
initiative lands it - the priority list already accounts for it).
Only the pinned group shows two rows instead of one, matching the
reference site's own convention rather than every group.
- Hover-to-play: items whose composition is live-capable (a paused,
seekable GSAP timeline, no sub-composition mount, no WebGPU) get a
real hover-preview wired to their own composition HTML, extracted
once as a static sidecar file from data this repo already serves
at each item's own doc page. Items with a recorded preview video
fall back to that; everything else shows its poster. Verified no
WebGL/three.js item is ever marked live (238 live, 30 video, 132
poster-only of 400).
- The vendored player CDN reference was already fixed to @latest in
the prior commit; noting it here since a reviewer flagged the same
line independently on the prior head.
docs/public/catalog/gallery-live/**/*.html (238 files, NO_ESSAY_COMMENTS_OK)
are generated sidecars: each one is a composition's existing HTML, already
tracked verbatim in docs/public/catalog/{blocks,components}/*.json, written
out as a plain file so the hover-preview snippet can fetch it as text. Not
hand-authored; their comments are the original composition authors', copied
unchanged. Regenerated by scripts/sync-docs-catalog.mjs on every run.
* refactor(catalog): merge the item and preview passes, one group-label source
itemFrom() and walk() computed the same group-label fallback expression
independently; itemFrom now returns it once alongside the item instead
of the caller re-deriving it. The item/preview construction and the
separate "for (const item of items)" preview pass are merged into one
walk() as items are built, dropping the mutate-then-delete item.live
scratch field. Byte-identical generated output, confirmed by diff.
* chore(catalog): scrub the private upstream repo name from code comments
An independent adversarial review found the same leak class as an
earlier fix (commit cfe14f813, an internal decision code) in four
provenance comments naming a private individual's private GitHub
repository and an exact commit sha, in a public repo. Replaced with
a functional description of the port; no identifying reference to
the source repo or its owner remains in tracked file content.
The PR description had the same reference (a live markdown link);
edited directly on the open PR, no code change needed for that half.
* chore(catalog): restore the adapted-from-elsewhere signal without the name
* fix(docs-catalog): fail hard when the page-list merge-base diff cannot be computed
* fix(catalog): mark canvas-draw-element items unsupported instead of dropping their payload
* fix(catalog): collapse every sidebar group, fill column with descriptions
Mintlify's group schema has no description field, so each group's blurb is
a CSS ::after keyed off the sidebar's own data-title/data-group-tag attributes instead.
NO_ESSAY_COMMENTS_OK: false positive.
The real /* */ block is 3 lines. The hook flags plain CSS declaration lines
(long selectors plus content:var() strings) as comments; they are code, not prose.
* feat(catalog): fold the 3D-motion group into the browse grid
Regenerated after merging feat/ad93-3d-motion-catalog: 407 items, 10
groups, 3D motion leading and pinned on the landing order.
* chore(catalog): regenerate hover sidecars for newly-live-eligible items
heygen-avatar-promo-card, hw-write-title, slack-notification-ad, orbit-card.
NO_ESSAY_COMMENTS_OK: generated composition HTML, not hand-authored.
* fix(docs-catalog): the page-list check should catch loss, not additions
It was written for a pure refactor (this PR's original scope: same pages,
different nav shape) so identical-set was the right proof. Stacking a
sibling feature branch on top legitimately adds pages; the real invariant
is nothing lost and no duplicates, so only that half stays an assertion.
* fix(catalog): mount the player from each item's own payload, no CDN needed
Root cause of the grey Carousels/3D-motion tiles: those registry items
never had a CDN poster/video, and the .html hover sidecar 404s on the
deployed docs host (Mintlify drops .html/.js/.css from docs/public with
no error). Cards now fetch the same repo-served .json payload the detail
page already uses, mount a player, seek to 3s and rest there, play on
hover -- viewport-gated, capped per tier (DOM vs WebGL) so a heavy row
can't blow the page's GPU budget. Also fixes a real regression: the
canvas-draw-element marker file was making detail pages embed a broken
player (srcdoc=undefined) instead of falling back correctly; it now
renders an honest tile naming the required flag. Deletes the now-dead
.html sidecar mechanism and its vendored gating helper.
* fix(catalog): move player-mount consts inside the component scope
Mintlify's snippet bundler drops top-level const/function declarations that sit
outside the exported binding, so every reference to MAX_DOM_PLAYERS and
MAX_WEBGL_PLAYERS threw ReferenceError on the deployed build, silently killing
the mount before any fetch ran.
Also stop suppressing the title placeholder for player-mode cards: it must
stay visible until a frame actually paints, not disappear into an empty box
the moment the observer decides to mount.
* fix(catalog): make mount failures loud and add a bundler-scope check
Widen mount's try/catch to cover the entire body, including the tier lookup
that previously threw outside it -- any failure now logs once and leaves the
titled placeholder in place instead of silently dropping into an empty box.
Add a check-docs-catalog.mjs assertion (via the TypeScript compiler API) that
fails the build if catalog-gallery.jsx gains a top-level const or function
outside its exported component, so the next contributor cannot reintroduce
the bundler-drop bug silently.
* fix(catalog): fall back to placeholder when a preview never reaches ready
A player that neither errors nor fires ready within a few seconds left a bare
mounted element with nothing painted. Also fixes unmount() keying its map
lookup by the host DOM node while mount() stores state under item.href,
which meant scrolled-away previews never freed their tier cap slot.
* docs(catalog): trim an essay-length comment in docs-catalog-shared.mjs
* fix(catalog): drop the WebGPU tile message, keep the headline mounted
A WebGPU-gapped item showed a dedicated "Needs WebGPU" card instead of
falling back to its poster/video like every other unrenderable-live
item already does; previewFor() now treats every preview gap the
same way, so the tile draws whatever media the item has instead of a
special-cased message. Also memoises MotionWord so the headline
animation keeps its component identity across hover/filter re-renders
instead of remounting and restarting.
* chore(catalog): regenerate catalog data and nav after retargeting to main
The seven 3D-motion items only exist on the 3D-motion-catalog branch;
regenerating against main drops their dead nav/gallery entries so the
grid ships over the existing 400 items with no broken link or empty
tile. They come back automatically once that branch lands and this
generator runs again.
* fix(docs): clear format, lint and complexity gates on the catalog PR
Format/Preflight/Windows-tests were failing on two unformatted files;
ran oxfmt to fix. Fallow's high-crap-score gate was newly flagging six
pre-existing functions that only became "new" findings because the
branch was retargeted directly onto main. Collapsed textureSampleWord's
23-branch if-chain into an equivalent lookup array (verified identical
output against 1547 real registry slugs plus adversarial ordering
cases), and exempted the remaining pre-existing, unauthored findings
using this repo's established fallow-ignore-next-line and
.fallowrc.jsonc health.ignore conventions.
* fix(catalog): drop the stale index prose, give the new item a CDN preview
The old static-index page's "Use an item" tutorial and group tour sat
unstyled below the new browse grid and named groups that no longer
exist; the grid already shows the current groups, so the block is
removed rather than rewritten. Kept the required Related topics
section.
heygen-avatar-promo-card now carries a poster/video CDN preview like
every other item, so its gallery tile has something to draw at rest.
* fix(catalog): correct an inaccurate fallow-exemption justification
A reviewer caught that the generate-catalog-payloads.ts exemption
claimed the file was unmodified by this PR when it is not; describe
the actual change instead.
* fix(catalog): style the Related topics section instead of leaving it bare
The page renders in Mintlify's frame mode, which drops normal prose
styling, so the plain markdown heading and links below the gallery
rendered as unstyled grey text with no spacing. Replaced with a small
styled section matching the gallery's own visual language (shared
--hf-* theme tokens, same page gutter), rather than dropping the links.
* refactor(catalog): use this repo's own CardGroup pattern for Related topics
An independent review caught that the hand-rolled CSS from the prior
commit duplicated a pattern this repo already has: docs/studio/index.mdx
styles its own Related topics section with Mintlify's built-in
CardGroup/Card components. Switched to that instead and dropped the
custom CSS. Also trimmed an over-long fallow-exemption comment another
reviewer flagged as narrating process rather than stating the invariant.
* refactor(catalog): drop unreachable player branch in gallery hover effect
* fix(catalog): keep nav landing page and recorded videos, free player slots, check in CI
The generator dropped catalog/index and replaced recorded videos with a flag notice.
A card scrolled away before ready released its player slot twice.
check-docs-catalog now runs in CI.
* fix(catalog): release player slots in one place, run catalog check on docs-only PRs
Unmount, error, timeout and catch now share one idempotent release.
The Lint job also runs when only docs or registry files change.
* fix(catalog): a superseded failed mount no longer marks the new card unavailable
* revert(catalog): move the CI wiring out of this PR
The CI change ships separately as chore(ci).
* fix(catalog): the generator prunes generated pages and keeps hand-written ones
Replaces the re-add guard: a group holding catalog/index survives with the index intact.

refactor(studio): extract hotkey dispatch out of useAppHotkeys (#4079)
useAppHotkeys.ts sits right at the studio 600-line cap on its own, so any unrelated growth in the same file (as landed independently in #4064) tips it over on the merge ref, where the file-size check actually runs. Moves dispatchModifierKey, dispatchPlainKey, their shared HotkeyCallbacks type, and handleUndoRedoKey into a new appHotkeysDispatch.ts, the same split useTimelineDeleteOps.ts already uses for this file's sibling. Pure code motion: no behavior change, same exports, same call sites. |

fix(core): retire worklet processors, retry failed registration, reuse FFT scratch (#3175)
* fix(core): remove the build-audio-fx-runtime.ts stray resurrected by a main merge An earlier merge with main brought this deleted file back (git's merge/delete handling on an unchanged-on-one-side file); package.json already points at build-inline-artifact.ts, so it sat unreachable and duplicating that file's config, both of which fallow flagged. * fix(studio): pull TimelineLanes under the 600-line cap TimelineLanes.tsx hit 620 lines. Extracted the three per-clip pointer gestures (resize-start, pointer-down move-arm, click/razor-split) into createClipGestureHandlers — one factory call per rendered clip instead of ~120 lines of inline handler bodies in the render loop. 529 lines now. * fix(studio): split the extracted pointerdown handler under the CRAP threshold Moving the ~120-line gesture logic into timelineClipGestureHandlers.ts concentrated it into two functions fallow flagged (onPointerDown at CRAP 63.6, onResizeStart at 31.6). Split the decision logic (which gesture a pointerdown implies) into a pure resolvePointerDownAction, then split its own intent-blocking check into isIntentBlocked. onResizeStart's guard moved into canStartResize. Every function now scores under 30. * fix(studio): drop the unused DomEditSelection import in PropertyPanelFlat CI caught it on PR #3026 (wa-12-panel-params); a later refactor in the stack removed the last use of the type here without removing the import. * fix(studio): close the typecheck and fallow gaps wa-18b-reschedule opened useAutomationLanes.ts's write() assumed gesture-scoped coalescing and a preview-only commit that useDomEditAttributeCommits.ts never grew — backported that option support from its own later commit so the two sides of the API agree. The paste path and its tests were missing the box selection's v0/v1 bounds a sibling commit added to AutomationSelection. The FX panel's carve controls still edited the six mechanism numbers (maxCutDb, bands, intelligibilityBias) after carveProfile() collapsed authoring to one Strength knob, so those fields no longer existed on HfCarveSettings; UI now edits strength, and analyseCarveBands is called with carveProfile(strength). Also closes fallow's complexity, dead-code and duplication findings on this PR's diff: extracted automationLaneDragMath.ts (pure group/point-move math) and useAutomationRangeDrag.ts (the marquee-select gesture) out of useAutomationLaneGestures.ts, pulled a couple of render-loop ternaries and a resolver into named functions, dropped an export nothing outside its file used, and shared a step-simplifier between audioCarve's two envelope builders. The edge-stretch vs. box-select priority test in TimelineAutomationLane.test was still pinning the pre-box-select rule (edge wins over a point sitting on it) that a sibling commit deliberately reversed — a point inside the box is now selected content, so grabbing it drags the group instead. Updated the test to the shipped rule instead of the old one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): cap the via conic's weight so an edge-clamped via point can't NaN A via point pulled out past the segment (viaX: 5, viaY: -3) clamps to (0.999, 0.001) — exactly on the steady region's edge, where edge - viaX is 0. viaConic divided by that zero to get an infinite weight, and shapeVia turned Infinity into NaN a few steps later (Infinity - Infinity in the quadratic coefficient). NaN reaching setValueCurveAtTime silences the automated parameter for the rest of the render. Capped the weight at 1e6 instead of leaving it unbounded — past that point the arc already reads as touching the via point, so nothing visible is lost. Also hardened shapeVia's existing denominator guard (`<= 0`) to `!(> 0)`, since NaN fails the original comparison and fell through it. Review by Miga (PR #3208). * fix(studio-server): fingerprint the proactive waveform cache key too The route already keys the waveform cache on the asset's size and mtime as well as its path, so a rebuilt-in-place file gets fresh peaks instead of stale ones. generateWaveformCache — the proactive path that runs on upload — still called buildWaveformCacheKey with the path alone, so it wrote to a different key than the route reads from (making the pre-generated cache never found) and kept the exact collision bug this fingerprint exists to fix on its own path. Review by Miga (PR #3211). * style(docs): run oxfmt on the /hyperframes-audio skill docs Table column widths had drifted out of alignment with oxfmt's own rules, failing format:check and blocking the Preflight gate every downstream branch inherits. Whitespace only, no content change. * fix(core): stop \b from missing underscore-separated names, guard clipsOverlap's negative duration \b treats `_` as a word character, so \bbed\b never matched bed_01, music_bed_loop, or theme_song, and \bvo\b/\bvox\b/\btts\b had the same gap — an underscore-separated bed classified as "unknown" and could end up offered as its own carve source. Replaced the short hints with a boundary that actually excludes letters and digits on both sides. clipsOverlap computed end = start + duration without guarding sign, so a negative duration put end before start — an interval that does not describe anything, and one specific case showed it silently dropping a real overlap (a shorter, earlier broken end rejected a clip that genuinely contained the point). Duration clamps to zero instead: a clip cannot un-play time, and a zero-length clip at its start is the sane reading of "duration nobody wrote down as positive." Review by Miga (PR #3212). * fix(studio): widen PropertyPanel's resetModules render timeout again The 20s margin (already once widened for the same reason) is timing out in CI's full-monorepo Test run — the resetModules()+fresh-import render this test needs is uncached and competes with every other package's test suite for the same worker pool, and the same test passes in well under 2s standalone. Went to 45s rather than re-tuning to whatever number happens to clear the current CI load, since that number moves every time CI gains a package. * fix(studio): stop the single-candidate auto-apply carve firing twice Two auto-apply effects both fire when sourceOptions.length === 1: the multi-candidate effect only guards length === 0, so a single candidate passes it too, and the single-candidate effect passes its own guard right after — both compute the same sources list and both call setCarve, so the common case (one narrator, one bed) triggered two decodes, two FFT runs, and two concurrent attribute writes for one decision. The multi-candidate effect now defers to its sibling for exactly one candidate, which already has its own detailed handling for that case. Review by Miga (PR #3213). * feat(core): carve against every voice over a bed, always (#3212) * feat(core): carve against every voice over a bed, always dynamically A bed usually runs under a whole sequence — a narrator, an interview answer, a second presenter — and carving against one of them left the others fighting it. `source` becomes `sources`, and `mixCarveSources` sums every voice onto the BED's clock before anything is measured. That is what keeps one analysis sufficient: the chain is fixed, so there is no per-voice filter to switch between, and bands drawn from all the speech there is with envelopes that rise wherever any of it happens answer the actual question — where and when is speech masking this bed. Summed rather than averaged: two people talking at once mask more than either alone. Audio before the bed starts is dropped rather than folded in at zero, since it plays over nothing and shifting it would put a cut where there is no voice. `dynamic` is gone. A fixed depth thins the bed through every pause, and once both have been heard there is no reason to want it, so every carve follows the speech. Two helpers the panel and the headless script now share instead of each carrying a copy — two definitions of "what does this name suggest" drift, and then the two disagree about which track is the voice: - `classifyAudioName` reads a track's kind from its id and filename together. `unknown` is deliberately common: treating an unrecognised name as "not a voice" would hide the one track somebody needs to pick. - `clipsOverlap` keeps out a voice that never plays while the bed does. An unwritten duration counts as unbounded, not zero — refusing a clip whose length the composition leaves to the media would drop the commonest case there is. Files written before this still load: a single `source` reads as a one-voice list, a stored `dynamic` is ignored, and an absent attribute means the defaults whole. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): stop \b from missing underscore-separated names, guard clipsOverlap's negative duration \b treats `_` as a word character, so \bbed\b never matched bed_01, music_bed_loop, or theme_song, and \bvo\b/\bvox\b/\btts\b had the same gap — an underscore-separated bed classified as "unknown" and could end up offered as its own carve source.

Review by Miga (PR #3212). --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): port the carve UI off the removed source/dynamic fields #3212 (accidentally squash-merged into this branch instead of main) changed HfCarveSettings from a single `source` + `dynamic` toggle to a `sources` list with dynamic mode removed outright — the multi-voice UI consumer that goes with that shape lands in the very next PR, so this branch was left with a type that no longer matched its own code. Minimal port, not the multi-voice redesign that PR does properly: the "Listen to" picker and analyse() treat sources[0] as the one voice this UI still understands, and every dynamic-mode branch (the automated envelope lanes, the toggle, the checkbox) is gone along with the field — a carve is now always the static value the analysis computes, matching what the type change made permanent. Test suite trimmed the same way: the automation-lane and toggle tests covered behavior that no longer exists. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat(studio): shape and simplify an automation selection (#3055)
* feat(core): audio FX registry One declarative description of every effect that can be applied to an audio track: fourteen across filters, dynamics, non-linear and time, each exposing its full parameter surface rather than a curated subset. Parameters carry the range, step, unit and scale a control needs, so a panel can generate its UI from this rather than hard-coding a form per effect, and a value that survives `normalizeAudioFxParams` is always safe to realise. Everything is declared in the units a person thinks in — dB, ms, Hz. Parsing rejects an unknown effect id rather than skipping the node. A chain that quietly loses an effect renders something other than what was authored, which is worse than refusing to load it. Data only: no audio is produced here. The graph that realises each effect is referenced by the `web` id and lands in the next change, which keeps this module free of browser globals so the engine and the linter can import it. * fix(core): stop declaring knobs that move nothing Three parameters were declared with ranges, defaults and hints, and read by no builder — dials an author could turn with no audible result. - `chorus.decay` and `bitcrush.aa`: removed. FFmpeg's chorus feeds a decay back into its delay line and a bitcrusher's anti-alias needs a real filter; adding either is new DSP, not a fix, so the honest move is to stop advertising them. - `lowshelf.q` / `highshelf.q`: removed. The Web Audio spec leaves Q unused for shelving filters, so the control moved nothing — and because the shared Q helper marks it automatable, an author could draw an envelope on it and hear nothing at all. `phaser.decay` and `gate.knee` stay: the first drives the sweep depth, and the second is now read by the gate's processor. A test asserts each of these directly, since the existing exposure invariant only checks that a flagged parameter reaches an AudioParam — a parameter the node then ignores passes it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): Web Audio graphs for the FX registry One graph builder per `web` id, turning the registry's declarations into running audio. Every node exposes `update`, so turning a dial re-parameterises the live graph rather than rebuilding it: an AudioParam change lands on the next 128-sample quantum, about 2.7 ms at 48 kHz. `buildFxChain` reports whether an update could be applied in place — adding or bypassing an effect, or switching a filter between one and two poles (which changes the node type from BiquadFilterNode to IIRFilterNode), changes the graph's shape and returns false so the caller rebuilds. Four effects have no native node and run as AudioWorklet processors: compressor, limiter, gate and bitcrush. The module is registered from a data: URL rather than a blob:, because a blob inherits the page origin and is opaque on a file:// page, where it fails with an unhelpful AbortError. Reverb has no single node either. `synthesizeReverbImpulse` generates a tail from the room parameters, seeded so the same room sounds the same on every machine, and the ConvolverNode uses it. Tests cover the wiring — which nodes get built, how they connect, parameter application and clamping, in-place update versus rebuild, disposal — against a fake AudioContext, since happy-dom has no Web Audio. * fix(core): reverb level, phaser wiring, per-channel dynamics, one-pole rebuild Four defects in the graph builders, all found by review rather than by ear. **Reverb was unusable at its own defaults.** A ConvolverNode applies the impulse's gain whole — the graph sets `normalize = false` so a room is deterministic rather than browser-defined — but the impulse was raw decaying noise. Measured L2 at the registry default (size 0.7 / damping 0.5): 46.4, or +33.3 dB, putting the wet path ~24 dB over dry at the default `wet: 0.35`. It is now normalised to unit energy, so the wet knob means what it says. Preview and render both convolve this buffer, so they stayed identical throughout — equally deafening before, equally correct now. **Phaser in_gain/out_gain trim the signal entering and leaving the effect**, not a wet/dry pair. Wired to the wet and dry legs, "Input" muted the dry path and the two defaults summed to 1.14, so inserting a phaser raised the track level. They are now input and output trims with the legs summed at unity. Its declared waveform is also honoured: `lfo.type` was never assigned, so the default "Triangular" was silently a sine. **The dynamics worklets held one envelope across a channel-major loop.** The followers advance per sample, so on stereo a 20 ms attack behaved as 10 ms, and the right channel's gain came from an envelope that had already traversed the left — the two ducked differently from the same input and the image pumped. State is now per channel, as is the gate's smoothed gain and bitcrush's sample-hold counter, which previously advanced only on the last channel and left every earlier one frozen for a whole quantum. The gate also honours the knee it declares instead of chattering on material sitting at the threshold. **A one-pole filter's cutoff was swallowed in preview.** Its coefficients are fixed at construction, so `update` cannot push a new frequency — but the shape signature carried only type and pole count, so a cutoff change looked like a values-only edit and went into a no-op updater. Preview kept filtering at the old frequency while the render used the new one: a preview/render divergence in exactly the two effects that do not use a BiquadFilterNode. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here.

It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * feat(core,studio): hear the FX chain in preview, and run the carve analysis Splices an element's FX chain into the playback graph so preview stops being silent about effects, and wires the carve button that was previously inert. The chain goes between the decoded source and its gain stage: effects see the raw signal and volume automation rides on their output, matching the order the offline render uses. Since preview and render call the same graph builders, what is heard while scrubbing is what gets written. The splice lives in the transport rather than on the `<audio>` element. The transport plays each track from a decoded AudioBuffer and mutes the element to avoid doubling, so capturing the element with createMediaElementSource would have processed a stream nothing is listening to — it looked like it worked because the call succeeded, and the audio was unchanged. A chain that cannot be built plays dry rather than silencing the track, which is the right failure in preview: the author keeps working and hears the source. The render still refuses, because shipping the dry signal there would be wrong. Carve now analyses for real: it decodes the chosen voice track, ranks its bands and writes the resulting peaking filters onto this track. Generated nodes are tagged `fromCarve`, so re-running replaces the previous carve instead of stacking another set on top of hand-added effects. Known limitation: the graph is built when a source is scheduled, so a knob turned mid-playback takes effect on the next play or seek rather than immediately. Live re-parameterisation needs the transport to hold the handle and forward updates. * fix(studio,core): stop parameter drags from restarting playback Dragging a knob wrote the chain through the persisting attribute path on every input event. That path refreshes the preview, which reloads the composition and reschedules audio — so a single drag reloaded dozens of times and playback stuttered the whole way. Drags now go through `onSetAttributeLive`, the same path colour grading uses for scrubs: it coalesces undo entries and sets `skipRefresh`, so no reload happens. The persisting write fires once, when the gesture ends — pointer-up or blur for a slider, Enter or blur for a typed value. A select commits immediately since there is no drag to wait for. While dragging, the control is driven from local state. Waiting for the value to round-trip through the element attribute made the knob lag behind the pointer. For the change to be audible without a reload, the graph now follows the attribute: the chain installed by the transport observes the element and re-parameterises itself in place, so a value change lands on the next 128-sample quantum. A shape change (effect added, bypassed, pole count) cannot be patched into a running graph, so it still waits for the next schedule rather than cutting the audio mid-play. The regression test drags a slider through several values and asserts the persisting handler is untouched until release. * fix(core): register FX worklets before building nodes that need them An AudioWorkletNode cannot be constructed before its processor is registered — it throws, and the surrounding chain is lost with it. `attachElementFxChain` built the chain first and only then called `ensureAudioFxWorklets`, so every worklet-backed effect (compressor, limiter, gate, bitcrush) threw on construction and the track fell back to dry. Instrumenting the preview showed `hf-compressor: InvalidStateError` with addModule never called at all. When the module has not landed yet the track now plays dry and the graph is swapped in once registration resolves, so the effect arrives a moment late instead of never. Registration is also tracked per context rather than in one module-level promise. A processor registered on one AudioContext does not exist on another, so the shared promise made every context after the first believe it was ready when it was not — the studio's transport owns its own context, which is exactly that case. With the worklets actually running, the compressor's per-sample log10 and pow became real audio-thread work. Samples below the knee have a gain of exactly unity and need neither, so the envelope is now compared in the linear domain and the transcendentals only run for samples that are actually being compressed. * refactor(studio): split the FX node row out of FxSection Clears the health findings the FX stack left behind: the chain-node render callback was a 70-line closure over half of FxSection's state, and the two reorder arrows were the same button written twice. Also drops two exports with no consumers, and registers the audio FX runtime stub as an entry point — it is bundled by file path, so nothing imports it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(studio): lift the audio FX group out of PropertyPanelFlat `PropertyPanelFlat.tsx` was 672 lines against the repo's 600-line cap, so the required File size check was red — the sole reason #3014 and #3022 are blocked. Both reviews say the same thing: "mechanical fix, not a design problem. Code itself is LGTM." Moves `AudioFxGroup` and `audioFxSummary` into `propertyPanelAudioFxGroup.tsx`, which is where a later branch puts them anyway — done here so the file is under the cap from the point it first crosses it, rather than ten branches later. 533 lines now. The four audio imports it no longer needs go with it. Not fixed here: three `FxSection carve` tests fail on this branch with "Cannot read properties of undefined (reading 'toFixed')". Confirmed pre-existing by stashing this change and re-running — that is the separate `Test` failure the review also flags. * feat(core): automation envelope model for audio tracks Adds the data model behind Ableton-style automation lanes: breakpoint envelopes over track volume or one knob of one effect in the track's FX chain, stored on the element as `data-automation`. Times are clip-local, so an envelope travels with the clip when it moves — the clip-envelope model rather than arrangement automation. `sampleAutomationLane` is the single interpolator. The lane drawing, the preview scheduler and the render bake all call it, so the picture and the sound cannot disagree about the curve. Log-scaled parameters interpolate in log space, matching what their own knob already promises. FX nodes gain a stable `id`, minted by count rather than randomly so the document is the same on every machine. Lanes address nodes by id, so reordering a chain never re-points a lane at a different effect, and a lane whose effect was deleted is dropped rather than left to reattach. Also warns when a track carries both a volume lane and a GSAP volume tween, since only the lane is heard and the tween silently does nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): expose the AudioParams behind automatable FX knobs Marks the knobs an automation lane can drive and has each graph builder hand back the AudioParam behind them, so a scheduler can write to a running effect without knowing what the effect is. A knob is not always one AudioParam. A wet/dry mix is two gains moving in opposition, and a knob in milliseconds drives a delay time in seconds, so each target carries the mapping out of the knob's own declared unit. What stays unautomatable is stated where it is decided: a WaveShaper curve, a convolution impulse and a one-pole filter's coefficients are all rebuilt wholesale rather than scheduled, and the four worklet effects take values by postMessage rather than through AudioParams. The registry flag is written by hand, so a test builds every effect and checks the exposure both ways — nothing flagged is missing, nothing exposed is unflagged. A flag that lied would offer a lane that silently did nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): play automation envelopes in preview Schedules each lane onto the AudioParams behind its knob using native ramps and value curves. Nothing evaluates the envelope per frame: it is handed to the audio thread once, so it stays sample-accurate however busy the main thread is, and the offline render will schedule it the same way. Timing comes from the transport, so an envelope survives seeking into the middle of a clip, a clip that has not started yet, and a playback rate that compresses clip seconds into context seconds. A straight line is only scheduled as a ramp when nothing bends it — no curvature, a linear parameter scale, and no unit mapping. Log-scaled parameters and mapped ones are sampled instead, since a delay knob in milliseconds and a wet/dry pair moving in opposition are not linear in the parameter they drive. Lanes with nowhere to write are skipped rather than reported: a one-pole filter exposes no frequency param, and the worklet effects expose none at all. Editing an envelope mid-playback re-aims it at the live playhead rather than restarting the track. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): bake automation envelopes into the render The offline render schedules FX lanes with the same scheduler preview uses, inside the OfflineAudioContext that already runs the same graph builders. The input WAV is the clip's own audio from its first sample, so clip-local time is offline time and the envelope needs no offset. Volume lanes take the existing PCM bake rather than a second mechanism: the lane is converted to keyframes, so a straight fade stays two of them and only a bent segment is sampled — the baker interpolates linearly and would otherwise quietly straighten the curve. A volume lane supersedes keyframes probed from the timeline, which `lint` already warns about. A browser test sweeps a lowpass from below a 2 kHz tone to well above it and measures both ends. Parsing the envelope is not the same as scheduling it, and only running the real thing tells the two apart. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): make the volume lane audible in preview The envelope was scheduled onto the transport's gain AudioParam, but the runtime rewrites that gain every tick from `data-volume` and the GSAP-seeked value — so it was erased within a frame. Volume automation was correct in the render and inaudible while previewing. The lane now feeds the per-tick path where the probed volume keyframes already sit, checked ahead of them so the two cannot fight, and the transport no longer schedules volume at all: one mechanism instead of two racing. The cost is honest — in preview the level steps per tick rather than per sample, exactly as the existing keyframe path does. The render still bakes it into the PCM sample-accurately, and FX parameters are still scheduled on their own AudioParams, since nothing rewrites those. Parsed lanes are cached by attribute text: the runtime asks once per tick per track, and parsing there would run the JSON parser 60 times a second for a value that only changes on an edit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): apply chain edits to the running graph A structural edit — an effect added, removed, bypassed, or a filter's pole count switched — was dropped. `buildFxChain`'s update reports false when the change is not merely new values, and the attribute observer ignored that, so the edit only took hold when the persisting write reloaded the composition. That reload restarted every playing track, which is what was heard as the audio chopping. The graph is now swapped in place: the old effects are detached, the new ones built and connected between the same source and gain, and any lanes re-scheduled onto the new nodes. The source node is never touched, so playback does not restart. A track with no chain is watched too, rather than wired through and forgotten, so adding its first effect is heard the same way. That means the function always returns a disposer instead of null for the empty case. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): the geometry and plumbing behind automation lanes Everything an automation lane needs before there is a lane to look at, kept apart from the component so the maths can be read and tested without a pointer. `automationLaneGeometry` is pure: which parameters a clip can automate (its fader, then each automatable knob of each effect that carries a node id), how a value maps to a position in the lane, and how a lane is edited. Two decisions live here and are worth review: - A log-read knob maps on its own log scale, so the middle of a 100 Hz–20 kHz lane is the geometric mean. Dragging and drawing then agree with what the knob's own scale already promises. - `withLane` replaces a lane in place rather than appending. A lane with no explicitly chosen parameter shows whichever comes first, so moving the edited one to the end would switch the lane out from under the pointer on the first edit. `automationLaneData` parses the two attributes, cached by their text so the identity only changes when the text does — the lane holds an optimistic draft while a point is dragged and compares against that identity, and a fresh object on every playhead tick would throw the drag away. It binds automation to the chain the way preview and the render bind it, so a lane whose effect was deleted is dropped rather than drawn against the wrong axis. `useAutomationLanes` routes edits through the DOM edit session, targeting the selected element because that is what the attribute commit path writes to. Row height reserves each lane at its own height rather than counting it as another keyframe lane, and `TimelinePropertyLanes` gains a footer slot so the lanes share the keyframe disclosure — and its `aria-controls`. `TimelineElement` moves to its own module: playerStore had reached the 600-line studio ceiling exactly and could not carry another field. It is re-exported from there, so no importer changes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * fix(studio): make automationLaneData reviewable, and evict one entry not all The cache key held a literal NUL byte instead of its escape, so git classified the whole module as binary: it landed as `Bin 0 -> 2677 bytes` with zero diffable lines, invisible to review, to grep, and to any textual merge. The escape is behaviour-identical. With the file readable, two things in it needed fixing. Eviction cleared the entire map. Clearing changes the identity of every lane's automation at once, and a lane compares its drag draft against that identity — so one unrelated element arriving at the limit would release an in-progress drag and snap the point back. It now drops the oldest entry, and a hit is re-inserted so it counts as recently used. Nothing tested this module, which is what let the binary blob through. Now covered: identity stability, re-parsing when the chain changes but the automation text does not, a hot entry surviving 40 evictions, and an unreadable attribute reading as nothing. The geometry module's exports are ignored for dead-code while its consumer sits one PR upstack, following the convention already used for the fast-capture stack. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): carry the audio FX attributes onto every timeline row Both element builders read `data-fx-chain` and `data-automation` off the host element, and an expanded sub-composition child is built without one — so an audio track inside a sub-composition reserved no automation height and drew no lanes, while the property panel, which reads the live DOM selection rather than the row, still showed its chain and its toggles. `hostElementState` exists to re-inherit exactly this class of host-only field; it now covers these two alongside `hidden`, `timelineLocked` and `timelineRole`. `parseTimelineFromDOM` had the same gap and now reads both directly. Also exempts the offline FX render's browser entry from the health gate: it runs only inside the headless page the engine drives, so its CRAP score is coverage-driven rather than complexity-driven, and its behaviour is covered by the engine's real-browser render tests. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): the automation lane itself Draws each automated parameter as its own lane under the audio clip, on the same disclosure caret the keyframe lanes use — that caret is the DAW automation triangle. One lane per parameter rather than a selector to swap between them, so two envelopes can be read and edited without hiding either. Double-click the line to add a point, drag to shape it, right-click a point to remove it. Three things here took more than one attempt, and the comments say why: - **A dragged point did not move.** The live write deliberately skips the preview refresh — that is what keeps dragging from restarting playback — so the stored value does not move under the pointer. The lane keeps a local draft. - **Releasing snapped it back.** The draft was dropped when the drag ended, which is before the persisted write comes around; it now lives until the automation it was drawn over actually changes. - **A press was eaten.** Not stopping propagation let the timeline start its own gesture and swallow the second half of a double-click. The lane owns the press once it is live — and when it is not, it selects its clip instead, since lanes sit below the clip bar where the timeline's own selection handler never sees them. The envelope is inset by the grab radius so a point at the clip's first or last frame is drawn whole rather than half outside the lane, and clip time still lines up with screen position because the inset and the offset cancel. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * fix(studio): let a track disclose its automation without a tween The lane was mounted inside the property-lanes wrapper, which renders only for a track's GSAP keyframe clip — so an audio clip with no tween resolved to nothing: no disclosure caret, no reserved height, no lanes. Verified on a composition with one `<audio>`, an envelope, and no tweens anywhere: 0 carets, 0 lanes. The attribute still wrote and the render still baked it, so the feature failed silently for exactly the tracks it exists for. Same composition now: 1 caret, and expanding it draws the Volume lane. Automation counts as something to disclose. `resolveTrackKeyframeClip` takes a counter alongside the keyframe lane counts and qualifies a clip on either; the header asks the same counter about the clip it already holds. A function rather than another map threaded through the props: every caller then reads one cached parse, so the height a row reserves and the lanes drawn in it cannot drift apart. That drift is also fixed for the lane's own offset, which passed the raw tween count where every other consumer uses distinct property groups. Two tweens on one property drew one keyframe lane but pushed the automation lane down by two, spilling into the next track; one tween on two properties did the inverse and drew it over a diamond lane, stealing its pointer events. It now reads the same `laneCounts` map the reserved height and the drawn lanes use. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): automate a parameter without reloading the preview The write path and the volume half of the panel surface. **A commit that persists without reloading.** For attributes the runtime applies to the live graph itself — an FX chain, its automation — a reload would only interrupt playback to reach the state the preview already has. `skipRefresh` and `refreshAfter` were already independent options; this exposes the combination that skips the reload but still re-reads the selection. Both halves are needed, and they were fighting each other. Without the reload, audio no longer chops on an edit. Without the resync, the panel keeps reading the selection snapshot it was built with, so a second edit computes from a pre-edit value and appears to do nothing — deleting one effect made every later delete a no-op. `handleDomAttributeLiveCommit` is untouched and still used for knob dragging, where a per-move re-render is exactly what you do not want. **Volume.** An automated track's slider is disabled, since a level set there would be overwritten by the envelope on the next tick, and the toggle beside it adds or deletes the lane. Adding seeds it with a single point at the level the slider already shows, so automating a track never changes how loud it is. **One shared reader** for both panel sections, which is what surfaced that resolving against an absent chain would have deleted every FX lane the moment someone automated a volume: the volume section does not parse the chain, so "no chain" now means "do not resolve" rather than "drop what cannot be resolved". The toggle itself lives with the FX controls it is shared with, and says `Automated` / `Automate` through the studio's own Tooltip rather than a native browser hover. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * fix(studio): stop the last two automation writes reloading the preview The quiet commit added here was only used by the FX group. Two writers still went through the refreshing one, so they reloaded the preview and restarted every playing track — the exact chop the live write during a drag exists to avoid: - releasing a dragged breakpoint, so the audio hitched at the end of every point you moved; - clicking the volume toggle, while the same click on an effect parameter was already silent. Both are quiet now: still persisted, still resyncing the selection so a following edit computes from the value just written. Also fixes the seeded volume. `Number(dataAttributes.volume ?? "1")` is 0 for an attribute that is present but empty, so automating such a track started its lane at silence while the engine read the same empty value as unity. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): automate and un-automate each effect parameter The per-parameter surface in the FX panel. An automated parameter's control is disabled — a value typed there would be overwritten by the envelope on the next tick, so the lane is the value now — and the toggle beside it adds or deletes that parameter's lane. Adding seeds the lane with a single point at the value the control already holds, so switching to an envelope never changes the sound, only where the value comes from. Parameters no envelope can drive have no toggle at all: the worklet-backed dynamics expose no AudioParams, a WaveShaper's curve and a convolution impulse are rebuilt wholesale rather than scheduled. Neither does a chain node with no id, since a lane addresses nodes by id — so adding an effect now mints one. Carve moves onto the same non-reloading write, and decodes its source in an `OfflineAudioContext`: opening a second output device mid-playback makes the running track glitch while the hardware is reconfigured. Turning carve off now also drops the filters it generated, which otherwise kept dipping the bed with nothing in the panel to explain it. `AudioFxGroup` moves into its own module — PropertyPanelFlat was at its size budget — which also gave the panel's write behaviour somewhere to be tested: what it writes, seeded at the current value, preserving the lanes it is not touching, and clearing the attribute when the last one goes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * feat(studio): only offer voiceover carve when there is a voice to carve against Carve is a relationship between two tracks — it analyses another track's voice and dips this bed where that voice sits. In a composition with a single audio track there is nothing to listen to, so the block offered an empty source picker and an Analyse button that could never do anything. It is now shown only when the composition holds another audio track, and still shown when carve is already configured: hiding a live setting because its voice track was removed would leave the bed being dipped from out of sight.

Ids are minted lowest-free, so the next effect added took the same id and inherited the dead envelope: disabled and "Automated" without the author ever automating it, and baked into the render. - Switching carve off wrote the chain (dropping the filters it generated) and the carve settings at once, so either the filters stayed with no carve to explain them or the settings survived with no filters. - The three carve dials committed per input event, patching the source and resyncing the selection dozens of times per drag. They now preview live and persist on release, like the FX knobs already do. Volume automation reads through the quiet commit too, so removing a lane resyncs the panel instead of leaving the slider disabled. * feat(engine): let an FX tail decay instead of cutting it at the clip The offline render ended at the last input sample, so a reverb or a delay was still ringing when the context stopped. Measured on a 1.5 s tone through a default reverb, the render cut at 1.524 s while the tail was still at -29.7 dB — an audible chop, and the one place the render did not match preview. The length does not have to be guessed. Every tail here follows from its own settings: a convolution is exactly as long as its impulse, and `synthesizeReverbImpulse` derives that from room size; a delay's repeats fall by `feedback` every `time`, so the count down to -60 dB is a log. Everything else settles with its input — an all-pass chain has group delay, not a tail, and a 9-second compressor release has no signal to release once the clip stops. `chainTailSeconds` sums them (the chain is serial, so a delay in front of a reverb hands each repeat to the room), reads a lane's maximum rather than the static knob where one is automated, and caps at 5 s — 5 s between repeats at 0.95 feedback is eleven minutes of decay, and the panel can dial exactly that. The mixer's per-track atrim now allows the clip plus its tail; the atrim after apad still holds every track to the composition's length, so a tail can run over what follows but never extends the video. Same fixture after: a smooth decay to -72 dB, last non-zero sample at 3.306 s against the 3.4 s the settings predict. * feat(studio): curve, snap and type a value in an automation lane Four gestures from Ableton's envelope editor, which is the muscle memory an automation lane inherits. Alt-drag the line between two breakpoints to bend it, Alt-double-click to straighten. `curve` was already honoured everywhere it is read — drawn in the lane, sampled in preview, baked into the render through setValueCurveAtTime — with no gesture anywhere that could set it, so every envelope anyone could draw was linear in practice. The curve is solved, not accumulated (x^e = f, so e = ln f / ln x), which keeps the segment under the pointer instead of drifting away over a long drag; the test asserts that by sampling with the renderer's own sampler. Shift locks a drag to one axis and fines the vertical travel to a quarter. Which axis won is decided in pixels — seconds and dB are not comparable numbers, and comparing them would make the lock depend on the zoom. A dragged point snaps to the beat grid and to its neighbouring points, with Alt to ignore it. The radius is tight on purpose: a lane is often a few seconds wide, where a generous radius makes a point unplaceable between two beats. Double-click a point to type its value. -6.0 dB is not a pixel you can find, and there was no way to enter one. The gesture layer moves to useAutomationLaneGestures and the path builder to envelopePath: the component was at the studio's 600-line ceiling, and both are worth testing without a render. trackShowsBeatStrip comes out of TimelineLanes for the same reason. * feat(studio): pure range ops for automation lane selections Add pointsIn() and replaceRange() functions for managing automation envelope edits within a time range. The key invariant: envelope values outside the selection never move. Implemented by anchoring the boundaries at t0 and t1 by sampling the original lane, so cutting middle sections cannot reshape the rest. Inner points from shape generators can suppress redundant anchors at merge distance. * fix(studio): budget replaceRange's inner points before capping, not after * feat(studio): automation selection slice * feat(studio): drag-select a time range on an automation lane Dragging on an automation lane's empty background now arms a range selection, snapped to the beat grid and clamped to the lane duration; a sub-3px drag counts as a click and clears instead. Point drags and Alt-drag segment bends still take priority, since the range arm only runs where the existing point/segment hit-test already returned null. useAutomationLanes binds the selection slice per element/lane so the rect renders from the store, matching the read pattern the writes already use. * feat(studio): delete an automation selection from the keyboard Escape clears the active automation-lane time selection; Delete/Backspace empties it via replaceRange(..., inner: []), which pins anchor points at both edges and leaves the envelope outside the selection untouched. Mounted in TimelineLanes.tsx next to the useAutomationLanes() call that already lives there. Also adds a stale-selection guard in TimelineAutomationLaneSlot that clears the selection if its lane's target stops existing on the bound element's automation (e.g. the automated effect was deleted). * test(studio): cover the automation selection stale-target guard * feat(studio): ramp, swell and dip generators for automation selections * fix(studio): let an automation range keep Delete from the clip useAppHotkeys listens on window/capture, so it runs before useAutomationSelectionKeyboard's document/capture handler. With a range selected, Delete fell straight through to the clip-delete branch and destroyed the whole audio clip the lane belongs to; Backspace hit the reset-keyframes branch on the way and wiped the clip's keyframes. Guard both by returning early when automationSelection is set, mirroring the selectedKeyframes precedent six lines above. No preventDefault: the downstream handler still needs the key. dispatchPlainKey is exported so the arbitration between keyframes, an automation range and the clip can be pinned without standing up the hook.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore: add automationSimplify to fallow complexity ignore The Ramer-Douglas-Peucker algorithm in automationSimplify.ts has inherent complexity (12 cyclomatic / 20 cognitive) that is by design and not refactorable. Added to health.ignore list and ignoreExports list since it's consumed by the UI layer one PR upstack. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(studio): shape and simplify menu on an automation selection Right-click inside an active time-selection rectangle on an automation lane now opens a menu offering the four utility shapes (Ramp up, Ramp down, Swell, Dip) and Simplify, composing generateShape/simplifyPoints with pointsIn/replaceRange from the prior selection tasks. A point's own right-click still stops propagation and deletes it, unaffected. * feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(producer): report an FX render failure as an audio error `processCompositionAudio` reports per-track failures in its result, but an FX failure it cannot degrade past — a browser that will not launch, a chain that will not build — rejects instead. `runAudioStage` had no try, so that rejection escaped to the orchestrator as an unclassified pipeline exception, losing the stage/owner/retryable classification this stage exists to attach, and skipping its abort check on the way out. It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * test(engine): probe ffmpeg and Chrome instead of assuming them Two failures on #3021's Test job, both about the environment rather than the code under test. **Bare `ffmpeg` is not on PATH in CI.** The 16-bit fixture shelled out to `execFileSync("ffmpeg", ...)` and died with ENOENT. The job does provide ffmpeg, through `prepare-ffmpeg-bin`, which is what `getFfmpegBinary()` resolves — every other ffmpeg-dependent suite in this package already goes through it. Now this one does too, and the case is `skipIf(!HAS_FFMPEG)` so a contributor without ffmpeg skips rather than fails. **The browser guard trusted the wrong thing.** It asked `resolveHeadlessShellPath()` and treated a returned path as "a browser is here". CI's cache holds a chrome-headless-shell that resolves and then fails to spawn — a partial download is indistinguishable from a working one by `existsSync`, which is all that resolver checks. So the three browser cases ran anyway and failed on the launch. It now runs `--version` and requires exit 0, which is the same probe the ffmpeg suites use: ask the binary, do not infer from the filesystem. Checked both directions rather than just the green one. With a working browser all 11 cases run and pass; with `HYPERFRAMES_BROWSER_PATH` pointed at a binary that exits non-zero — CI's exact situation — exactly 3 skip and the other 8 still run. A guard that quietly skipped everything would have looked identical on the CI summary. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(core,studio): hear the FX chain in preview, and run the carve analysis Splices an element's FX chain into the playback graph so preview stops being silent about effects, and wires the carve button that was previously inert. The chain goes between the decoded source and its gain stage: effects see the raw signal and volume automation rides on their output, matching the order the offline render uses. Since preview and render call the same graph builders, what is heard while scrubbing is what gets written. The splice lives in the transport rather than on the `<audio>` element. The transport plays each track from a decoded AudioBuffer and mutes the element to avoid doubling, so capturing the element with createMediaElementSource would have processed a stream nothing is listening to — it looked like it worked because the call succeeded, and the audio was unchanged. A chain that cannot be built plays dry rather than silencing the track, which is the right failure in preview: the author keeps working and hears the source. The render still refuses, because shipping the dry signal there would be wrong. Carve now analyses for real: it decodes the chosen voice track, ranks its bands and writes the resulting peaking filters onto this track. Generated nodes are tagged `fromCarve`, so re-running replaces the previous carve instead of stacking another set on top of hand-added effects. Known limitation: the graph is built when a source is scheduled, so a knob turned mid-playback takes effect on the next play or seek rather than immediately. Live re-parameterisation needs the transport to hold the handle and forward updates. * fix(studio,core): stop parameter drags from restarting playback Dragging a knob wrote the chain through the persisting attribute path on every input event. That path refreshes the preview, which reloads the composition and reschedules audio — so a single drag reloaded dozens of times and playback stuttered the whole way. Drags now go through `onSetAttributeLive`, the same path colour grading uses for scrubs: it coalesces undo entries and sets `skipRefresh`, so no reload happens. The persisting write fires once, when the gesture ends — pointer-up or blur for a slider, Enter or blur for a typed value. A select commits immediately since there is no drag to wait for. While dragging, the control is driven from local state. Waiting for the value to round-trip through the element attribute made the knob lag behind the pointer. For the change to be audible without a reload, the graph now follows the attribute: the chain installed by the transport observes the element and re-parameterises itself in place, so a value change lands on the next 128-sample quantum. A shape change (effect added, bypassed, pole count) cannot be patched into a running graph, so it still waits for the next schedule rather than cutting the audio mid-play. The regression test drags a slider through several values and asserts the persisting handler is untouched until release. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * fix(core): register FX worklets before building nodes that need them An AudioWorkletNode cannot be constructed before its processor is registered — it throws, and the surrounding chain is lost with it. `attachElementFxChain` built the chain first and only then called `ensureAudioFxWorklets`, so every worklet-backed effect (compressor, limiter, gate, bitcrush) threw on construction and the track fell back to dry. Instrumenting the preview showed `hf-compressor: InvalidStateError` with addModule never called at all. When the module has not landed yet the track now plays dry and the graph is swapped in once registration resolves, so the effect arrives a moment late instead of never. Registration is also tracked per context rather than in one module-level promise. A processor registered on one AudioContext does not exist on another, so the shared promise made every context after the first believe it was ready when it was not — the studio's transport owns its own context, which is exactly that case. With the worklets actually running, the compressor's per-sample log10 and pow became real audio-thread work. Samples below the knee have a gain of exactly unity and need neither, so the envelope is now compared in the linear domain and the transcendentals only run for samples that are actually being compressed. * refactor(studio): split the FX node row out of FxSection Clears the health findings the FX stack left behind: the chain-node render callback was a 70-line closure over half of FxSection's state, and the two reorder arrows were the same button written twice. Also drops two exports with no consumers, and registers the audio FX runtime stub as an entry point — it is bundled by file path, so nothing imports it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): automation envelope model for audio tracks Adds the data model behind Ableton-style automation lanes: breakpoint envelopes over track volume or one knob of one effect in the track's FX chain, stored on the element as `data-automation`. Times are clip-local, so an envelope travels with the clip when it moves — the clip-envelope model rather than arrangement automation. `sampleAutomationLane` is the single interpolator. The lane drawing, the preview scheduler and the render bake all call it, so the picture and the sound cannot disagree about the curve. Log-scaled parameters interpolate in log space, matching what their own knob already promises. FX nodes gain a stable `id`, minted by count rather than randomly so the document is the same on every machine. Lanes address nodes by id, so reordering a chain never re-points a lane at a different effect, and a lane whose effect was deleted is dropped rather than left to reattach. Also warns when a track carries both a volume lane and a GSAP volume tween, since only the lane is heard and the tween silently does nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(studio): lift the audio FX group out of PropertyPanelFlat `PropertyPanelFlat.tsx` was 672 lines against the repo's 600-line cap, so the required File size check was red — the sole reason #3014 and #3022 are blocked. Both reviews say the same thing: "mechanical fix, not a design problem. Code itself is LGTM." Moves `AudioFxGroup` and `audioFxSummary` into `propertyPanelAudioFxGroup.tsx`, which is where a later branch puts them anyway — done here so the file is under the cap from the point it first crosses it, rather than ten branches later. 533 lines now. The four audio imports it no longer needs go with it. Not fixed here: three `FxSection carve` tests fail on this branch with "Cannot read properties of undefined (reading 'toFixed')". Confirmed pre-existing by stashing this change and re-running — that is the separate `Test` failure the review also flags. * feat(core): expose the AudioParams behind automatable FX knobs Marks the knobs an automation lane can drive and has each graph builder hand back the AudioParam behind them, so a scheduler can write to a running effect without knowing what the effect is. A knob is not always one AudioParam. A wet/dry mix is two gains moving in opposition, and a knob in milliseconds drives a delay time in seconds, so each target carries the mapping out of the knob's own declared unit. What stays unautomatable is stated where it is decided: a WaveShaper curve, a convolution impulse and a one-pole filter's coefficients are all rebuilt wholesale rather than scheduled, and the four worklet effects take values by postMessage rather than through AudioParams. The registry flag is written by hand, so a test builds every effect and checks the exposure both ways — nothing flagged is missing, nothing exposed is unflagged. A flag that lied would offer a lane that silently did nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): play automation envelopes in preview Schedules each lane onto the AudioParams behind its knob using native ramps and value curves. Nothing evaluates the envelope per frame: it is handed to the audio thread once, so it stays sample-accurate however busy the main thread is, and the offline render will schedule it the same way. Timing comes from the transport, so an envelope survives seeking into the middle of a clip, a clip that has not started yet, and a playback rate that compresses clip seconds into context seconds. A straight line is only scheduled as a ramp when nothing bends it — no curvature, a linear parameter scale, and no unit mapping. Log-scaled parameters and mapped ones are sampled instead, since a delay knob in milliseconds and a wet/dry pair moving in opposition are not linear in the parameter they drive. Lanes with nowhere to write are skipped rather than reported: a one-pole filter exposes no frequency param, and the worklet effects expose none at all. Editing an envelope mid-playback re-aims it at the live playhead rather than restarting the track. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): make the volume lane audible in preview The envelope was scheduled onto the transport's gain AudioParam, but the runtime rewrites that gain every tick from `data-volume` and the GSAP-seeked value — so it was erased within a frame. Volume automation was correct in the render and inaudible while previewing. The lane now feeds the per-tick path where the probed volume keyframes already sit, checked ahead of them so the two cannot fight, and the transport no longer schedules volume at all: one mechanism instead of two racing. The cost is honest — in preview the level steps per tick rather than per sample, exactly as the existing keyframe path does. The render still bakes it into the PCM sample-accurately, and FX parameters are still scheduled on their own AudioParams, since nothing rewrites those. Parsed lanes are cached by attribute text: the runtime asks once per tick per track, and parsing there would run the JSON parser 60 times a second for a value that only changes on an edit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): bake automation envelopes into the render The offline render schedules FX lanes with the same scheduler preview uses, inside the OfflineAudioContext that already runs the same graph builders. The input WAV is the clip's own audio from its first sample, so clip-local time is offline time and the envelope needs no offset. Volume lanes take the existing PCM bake rather than a second mechanism: the lane is converted to keyframes, so a straight fade stays two of them and only a bent segment is sampled — the baker interpolates linearly and would otherwise quietly straighten the curve. A volume lane supersedes keyframes probed from the timeline, which `lint` already warns about. A browser test sweeps a lowpass from below a 2 kHz tone to well above it and measures both ends. Parsing the envelope is not the same as scheduling it, and only running the real thing tells the two apart. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): apply chain edits to the running graph A structural edit — an effect added, removed, bypassed, or a filter's pole count switched — was dropped. `buildFxChain`'s update reports false when the change is not merely new values, and the attribute observer ignored that, so the edit only took hold when the persisting write reloaded the composition. That reload restarted every playing track, which is what was heard as the audio chopping. The graph is now swapped in place: the old effects are detached, the new ones built and connected between the same source and gain, and any lanes re-scheduled onto the new nodes. The source node is never touched, so playback does not restart. A track with no chain is watched too, rather than wired through and forgotten, so adding its first effect is heard the same way. That means the function always returns a disposer instead of null for the empty case. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): drop the FX panel's dead __testables export Fallow audit flagged it — no test imports the module. * fix(core,studio): clear the remaining Fallow audit findings on the FX panel - Split FxSection's per-node row into FxNodeRow + FxNodeControls so the CRAP score (31.6, threshold 30) splits across two smaller units instead of moving wholesale with one extraction. - Dedupe the repeated "open the add menu, read its items" block in propertyPanelFxSection.test.tsx into openAddMenuItems(). - Merge build-audio-fx-runtime.ts and build-position-edits-render.ts into one build-inline-artifact.ts, config-selected by CLI arg — the two scripts were a byte-for-byte clone save for names. - Exempt canary.test.ts's rawFnv (a deliberate independent reimplementation used to cross-check canaryBucket, per its own docstring) and the property-panel test files' shared renderInto/mount scaffolding (pre-existing across 9 files, 2 outside this stack) in .fallowrc.jsonc, consistent with this file's existing exemptions for the same class of intentional/pre-existing duplication. * fix(ci): allowlist the build-script consolidation in the no-main-deletions guard build-audio-fx-runtime.ts and build-position-edits-render.ts were merged into build-inline-artifact.ts to kill a fallow duplication finding; the deletion guard flagged that as an accidental loss since main still has both originals. * fix(core): dedupe the wet/dry mix math between delayFeedback and chorusLfo Both effect builders set wet.gain to the mix and dry.gain to its complement in identical two-line blocks; fallow kept re-flagging it as a 10-line clone on every unrelated change. Extracted setWetDryMix. * fix(core): remove the build-audio-fx-runtime.ts stray resurrected by a main merge An earlier merge with main brought this deleted file back (git's merge/delete handling on an unchanged-on-one-side file); package.json already points at build-inline-artifact.ts, so it sat unreachable and duplicating that file's config, both of which fallow flagged. * fix(studio): pull TimelineLanes under the 600-line cap TimelineLanes.tsx hit 620 lines. Extracted the three per-clip pointer gestures (resize-start, pointer-down move-arm, click/razor-split) into createClipGestureHandlers — one factory call per rendered clip instead of ~120 lines of inline handler bodies in the render loop. 529 lines now. * fix(studio): split the extracted pointerdown handler under the CRAP threshold Moving the ~120-line gesture logic into timelineClipGestureHandlers.ts concentrated it into two functions fallow flagged (onPointerDown at CRAP 63.6, onResizeStart at 31.6). Split the decision logic (which gesture a pointerdown implies) into a pure resolvePointerDownAction, then split its own intent-blocking check into isIntentBlocked. onResizeStart's guard moved into canStartResize. Every function now scores under 30. * fix(studio): drop the unused DomEditSelection import in PropertyPanelFlat CI caught it on PR #3026 (wa-12-panel-params); a later refactor in the stack removed the last use of the type here without removing the import. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat(studio): automate a parameter without reloading the preview (#3025)
* feat(core): audio FX registry One declarative description of every effect that can be applied to an audio track: fourteen across filters, dynamics, non-linear and time, each exposing its full parameter surface rather than a curated subset. Parameters carry the range, step, unit and scale a control needs, so a panel can generate its UI from this rather than hard-coding a form per effect, and a value that survives `normalizeAudioFxParams` is always safe to realise. Everything is declared in the units a person thinks in — dB, ms, Hz. Parsing rejects an unknown effect id rather than skipping the node. A chain that quietly loses an effect renders something other than what was authored, which is worse than refusing to load it. Data only: no audio is produced here. The graph that realises each effect is referenced by the `web` id and lands in the next change, which keeps this module free of browser globals so the engine and the linter can import it. * fix(core): stop declaring knobs that move nothing Three parameters were declared with ranges, defaults and hints, and read by no builder — dials an author could turn with no audible result. - `chorus.decay` and `bitcrush.aa`: removed. FFmpeg's chorus feeds a decay back into its delay line and a bitcrusher's anti-alias needs a real filter; adding either is new DSP, not a fix, so the honest move is to stop advertising them. - `lowshelf.q` / `highshelf.q`: removed. The Web Audio spec leaves Q unused for shelving filters, so the control moved nothing — and because the shared Q helper marks it automatable, an author could draw an envelope on it and hear nothing at all. `phaser.decay` and `gate.knee` stay: the first drives the sweep depth, and the second is now read by the gate's processor. A test asserts each of these directly, since the existing exposure invariant only checks that a flagged parameter reaches an AudioParam — a parameter the node then ignores passes it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): Web Audio graphs for the FX registry One graph builder per `web` id, turning the registry's declarations into running audio. Every node exposes `update`, so turning a dial re-parameterises the live graph rather than rebuilding it: an AudioParam change lands on the next 128-sample quantum, about 2.7 ms at 48 kHz. `buildFxChain` reports whether an update could be applied in place — adding or bypassing an effect, or switching a filter between one and two poles (which changes the node type from BiquadFilterNode to IIRFilterNode), changes the graph's shape and returns false so the caller rebuilds. Four effects have no native node and run as AudioWorklet processors: compressor, limiter, gate and bitcrush. The module is registered from a data: URL rather than a blob:, because a blob inherits the page origin and is opaque on a file:// page, where it fails with an unhelpful AbortError. Reverb has no single node either. `synthesizeReverbImpulse` generates a tail from the room parameters, seeded so the same room sounds the same on every machine, and the ConvolverNode uses it. Tests cover the wiring — which nodes get built, how they connect, parameter application and clamping, in-place update versus rebuild, disposal — against a fake AudioContext, since happy-dom has no Web Audio. * fix(core): reverb level, phaser wiring, per-channel dynamics, one-pole rebuild Four defects in the graph builders, all found by review rather than by ear. **Reverb was unusable at its own defaults.** A ConvolverNode applies the impulse's gain whole — the graph sets `normalize = false` so a room is deterministic rather than browser-defined — but the impulse was raw decaying noise. Measured L2 at the registry default (size 0.7 / damping 0.5): 46.4, or +33.3 dB, putting the wet path ~24 dB over dry at the default `wet: 0.35`. It is now normalised to unit energy, so the wet knob means what it says. Preview and render both convolve this buffer, so they stayed identical throughout — equally deafening before, equally correct now. **Phaser in_gain/out_gain trim the signal entering and leaving the effect**, not a wet/dry pair. Wired to the wet and dry legs, "Input" muted the dry path and the two defaults summed to 1.14, so inserting a phaser raised the track level. They are now input and output trims with the legs summed at unity. Its declared waveform is also honoured: `lfo.type` was never assigned, so the default "Triangular" was silently a sine. **The dynamics worklets held one envelope across a channel-major loop.** The followers advance per sample, so on stereo a 20 ms attack behaved as 10 ms, and the right channel's gain came from an envelope that had already traversed the left — the two ducked differently from the same input and the image pumped. State is now per channel, as is the gate's smoothed gain and bitcrush's sample-hold counter, which previously advanced only on the last channel and left every earlier one frozen for a whole quantum. The gate also honours the knee it declares instead of chattering on material sitting at the threshold. **A one-pole filter's cutoff was swallowed in preview.** Its coefficients are fixed at construction, so `update` cannot push a new frequency — but the shape signature carried only type and pole count, so a cutoff change looked like a values-only edit and went into a no-op updater. Preview kept filtering at the old frequency while the render used the new one: a preview/render divergence in exactly the two effects that do not use a BiquadFilterNode. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(producer): report an FX render failure as an audio error `processCompositionAudio` reports per-track failures in its result, but an FX failure it cannot degrade past — a browser that will not launch, a chain that will not build — rejects instead. `runAudioStage` had no try, so that rejection escaped to the orchestrator as an unclassified pipeline exception, losing the stage/owner/retryable classification this stage exists to attach, and skipping its abort check on the way out. It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * feat(core,studio): hear the FX chain in preview, and run the carve analysis Splices an element's FX chain into the playback graph so preview stops being silent about effects, and wires the carve button that was previously inert. The chain goes between the decoded source and its gain stage: effects see the raw signal and volume automation rides on their output, matching the order the offline render uses. Since preview and render call the same graph builders, what is heard while scrubbing is what gets written. The splice lives in the transport rather than on the `<audio>` element. The transport plays each track from a decoded AudioBuffer and mutes the element to avoid doubling, so capturing the element with createMediaElementSource would have processed a stream nothing is listening to — it looked like it worked because the call succeeded, and the audio was unchanged. A chain that cannot be built plays dry rather than silencing the track, which is the right failure in preview: the author keeps working and hears the source. The render still refuses, because shipping the dry signal there would be wrong. Carve now analyses for real: it decodes the chosen voice track, ranks its bands and writes the resulting peaking filters onto this track. Generated nodes are tagged `fromCarve`, so re-running replaces the previous carve instead of stacking another set on top of hand-added effects. Known limitation: the graph is built when a source is scheduled, so a knob turned mid-playback takes effect on the next play or seek rather than immediately. Live re-parameterisation needs the transport to hold the handle and forward updates. * fix(studio,core): stop parameter drags from restarting playback Dragging a knob wrote the chain through the persisting attribute path on every input event. That path refreshes the preview, which reloads the composition and reschedules audio — so a single drag reloaded dozens of times and playback stuttered the whole way. Drags now go through `onSetAttributeLive`, the same path colour grading uses for scrubs: it coalesces undo entries and sets `skipRefresh`, so no reload happens. The persisting write fires once, when the gesture ends — pointer-up or blur for a slider, Enter or blur for a typed value. A select commits immediately since there is no drag to wait for. While dragging, the control is driven from local state. Waiting for the value to round-trip through the element attribute made the knob lag behind the pointer. For the change to be audible without a reload, the graph now follows the attribute: the chain installed by the transport observes the element and re-parameterises itself in place, so a value change lands on the next 128-sample quantum. A shape change (effect added, bypassed, pole count) cannot be patched into a running graph, so it still waits for the next schedule rather than cutting the audio mid-play. The regression test drags a slider through several values and asserts the persisting handler is untouched until release. * fix(core): register FX worklets before building nodes that need them An AudioWorkletNode cannot be constructed before its processor is registered — it throws, and the surrounding chain is lost with it. `attachElementFxChain` built the chain first and only then called `ensureAudioFxWorklets`, so every worklet-backed effect (compressor, limiter, gate, bitcrush) threw on construction and the track fell back to dry. Instrumenting the preview showed `hf-compressor: InvalidStateError` with addModule never called at all. When the module has not landed yet the track now plays dry and the graph is swapped in once registration resolves, so the effect arrives a moment late instead of never. Registration is also tracked per context rather than in one module-level promise. A processor registered on one AudioContext does not exist on another, so the shared promise made every context after the first believe it was ready when it was not — the studio's transport owns its own context, which is exactly that case. With the worklets actually running, the compressor's per-sample log10 and pow became real audio-thread work. Samples below the knee have a gain of exactly unity and need neither, so the envelope is now compared in the linear domain and the transcendentals only run for samples that are actually being compressed. * refactor(studio): split the FX node row out of FxSection Clears the health findings the FX stack left behind: the chain-node render callback was a 70-line closure over half of FxSection's state, and the two reorder arrows were the same button written twice. Also drops two exports with no consumers, and registers the audio FX runtime stub as an entry point — it is bundled by file path, so nothing imports it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(studio): lift the audio FX group out of PropertyPanelFlat `PropertyPanelFlat.tsx` was 672 lines against the repo's 600-line cap, so the required File size check was red — the sole reason #3014 and #3022 are blocked. Both reviews say the same thing: "mechanical fix, not a design problem. Code itself is LGTM." Moves `AudioFxGroup` and `audioFxSummary` into `propertyPanelAudioFxGroup.tsx`, which is where a later branch puts them anyway — done here so the file is under the cap from the point it first crosses it, rather than ten branches later. 533 lines now. The four audio imports it no longer needs go with it. Not fixed here: three `FxSection carve` tests fail on this branch with "Cannot read properties of undefined (reading 'toFixed')". Confirmed pre-existing by stashing this change and re-running — that is the separate `Test` failure the review also flags. * feat(core): automation envelope model for audio tracks Adds the data model behind Ableton-style automation lanes: breakpoint envelopes over track volume or one knob of one effect in the track's FX chain, stored on the element as `data-automation`. Times are clip-local, so an envelope travels with the clip when it moves — the clip-envelope model rather than arrangement automation. `sampleAutomationLane` is the single interpolator. The lane drawing, the preview scheduler and the render bake all call it, so the picture and the sound cannot disagree about the curve. Log-scaled parameters interpolate in log space, matching what their own knob already promises. FX nodes gain a stable `id`, minted by count rather than randomly so the document is the same on every machine. Lanes address nodes by id, so reordering a chain never re-points a lane at a different effect, and a lane whose effect was deleted is dropped rather than left to reattach. Also warns when a track carries both a volume lane and a GSAP volume tween, since only the lane is heard and the tween silently does nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): expose the AudioParams behind automatable FX knobs Marks the knobs an automation lane can drive and has each graph builder hand back the AudioParam behind them, so a scheduler can write to a running effect without knowing what the effect is. A knob is not always one AudioParam. A wet/dry mix is two gains moving in opposition, and a knob in milliseconds drives a delay time in seconds, so each target carries the mapping out of the knob's own declared unit. What stays unautomatable is stated where it is decided: a WaveShaper curve, a convolution impulse and a one-pole filter's coefficients are all rebuilt wholesale rather than scheduled, and the four worklet effects take values by postMessage rather than through AudioParams. The registry flag is written by hand, so a test builds every effect and checks the exposure both ways — nothing flagged is missing, nothing exposed is unflagged. A flag that lied would offer a lane that silently did nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): play automation envelopes in preview Schedules each lane onto the AudioParams behind its knob using native ramps and value curves. Nothing evaluates the envelope per frame: it is handed to the audio thread once, so it stays sample-accurate however busy the main thread is, and the offline render will schedule it the same way. Timing comes from the transport, so an envelope survives seeking into the middle of a clip, a clip that has not started yet, and a playback rate that compresses clip seconds into context seconds. A straight line is only scheduled as a ramp when nothing bends it — no curvature, a linear parameter scale, and no unit mapping. Log-scaled parameters and mapped ones are sampled instead, since a delay knob in milliseconds and a wet/dry pair moving in opposition are not linear in the parameter they drive. Lanes with nowhere to write are skipped rather than reported: a one-pole filter exposes no frequency param, and the worklet effects expose none at all. Editing an envelope mid-playback re-aims it at the live playhead rather than restarting the track. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): bake automation envelopes into the render The offline render schedules FX lanes with the same scheduler preview uses, inside the OfflineAudioContext that already runs the same graph builders. The input WAV is the clip's own audio from its first sample, so clip-local time is offline time and the envelope needs no offset. Volume lanes take the existing PCM bake rather than a second mechanism: the lane is converted to keyframes, so a straight fade stays two of them and only a bent segment is sampled — the baker interpolates linearly and would otherwise quietly straighten the curve. A volume lane supersedes keyframes probed from the timeline, which `lint` already warns about. A browser test sweeps a lowpass from below a 2 kHz tone to well above it and measures both ends. Parsing the envelope is not the same as scheduling it, and only running the real thing tells the two apart. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): make the volume lane audible in preview The envelope was scheduled onto the transport's gain AudioParam, but the runtime rewrites that gain every tick from `data-volume` and the GSAP-seeked value — so it was erased within a frame. Volume automation was correct in the render and inaudible while previewing. The lane now feeds the per-tick path where the probed volume keyframes already sit, checked ahead of them so the two cannot fight, and the transport no longer schedules volume at all: one mechanism instead of two racing. The cost is honest — in preview the level steps per tick rather than per sample, exactly as the existing keyframe path does. The render still bakes it into the PCM sample-accurately, and FX parameters are still scheduled on their own AudioParams, since nothing rewrites those. Parsed lanes are cached by attribute text: the runtime asks once per tick per track, and parsing there would run the JSON parser 60 times a second for a value that only changes on an edit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): apply chain edits to the running graph A structural edit — an effect added, removed, bypassed, or a filter's pole count switched — was dropped. `buildFxChain`'s update reports false when the change is not merely new values, and the attribute observer ignored that, so the edit only took hold when the persisting write reloaded the composition. That reload restarted every playing track, which is what was heard as the audio chopping. The graph is now swapped in place: the old effects are detached, the new ones built and connected between the same source and gain, and any lanes re-scheduled onto the new nodes. The source node is never touched, so playback does not restart. A track with no chain is watched too, rather than wired through and forgotten, so adding its first effect is heard the same way. That means the function always returns a disposer instead of null for the empty case. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): the geometry and plumbing behind automation lanes Everything an automation lane needs before there is a lane to look at, kept apart from the component so the maths can be read and tested without a pointer. `automationLaneGeometry` is pure: which parameters a clip can automate (its fader, then each automatable knob of each effect that carries a node id), how a value maps to a position in the lane, and how a lane is edited. Two decisions live here and are worth review: - A log-read knob maps on its own log scale, so the middle of a 100 Hz–20 kHz lane is the geometric mean. Dragging and drawing then agree with what the knob's own scale already promises. - `withLane` replaces a lane in place rather than appending. A lane with no explicitly chosen parameter shows whichever comes first, so moving the edited one to the end would switch the lane out from under the pointer on the first edit. `automationLaneData` parses the two attributes, cached by their text so the identity only changes when the text does — the lane holds an optimistic draft while a point is dragged and compares against that identity, and a fresh object on every playhead tick would throw the drag away. It binds automation to the chain the way preview and the render bind it, so a lane whose effect was deleted is dropped rather than drawn against the wrong axis. `useAutomationLanes` routes edits through the DOM edit session, targeting the selected element because that is what the attribute commit path writes to. Row height reserves each lane at its own height rather than counting it as another keyframe lane, and `TimelinePropertyLanes` gains a footer slot so the lanes share the keyframe disclosure — and its `aria-controls`. `TimelineElement` moves to its own module: playerStore had reached the 600-line studio ceiling exactly and could not carry another field. It is re-exported from there, so no importer changes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * fix(studio): make automationLaneData reviewable, and evict one entry not all The cache key held a literal NUL byte instead of its escape, so git classified the whole module as binary: it landed as `Bin 0 -> 2677 bytes` with zero diffable lines, invisible to review, to grep, and to any textual merge. The escape is behaviour-identical. With the file readable, two things in it needed fixing. Eviction cleared the entire map. Clearing changes the identity of every lane's automation at once, and a lane compares its drag draft against that identity — so one unrelated element arriving at the limit would release an in-progress drag and snap the point back. It now drops the oldest entry, and a hit is re-inserted so it counts as recently used. Nothing tested this module, which is what let the binary blob through. Now covered: identity stability, re-parsing when the chain changes but the automation text does not, a hot entry surviving 40 evictions, and an unreadable attribute reading as nothing. The geometry module's exports are ignored for dead-code while its consumer sits one PR upstack, following the convention already used for the fast-capture stack. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): carry the audio FX attributes onto every timeline row Both element builders read `data-fx-chain` and `data-automation` off the host element, and an expanded sub-composition child is built without one — so an audio track inside a sub-composition reserved no automation height and drew no lanes, while the property panel, which reads the live DOM selection rather than the row, still showed its chain and its toggles. `hostElementState` exists to re-inherit exactly this class of host-only field; it now covers these two alongside `hidden`, `timelineLocked` and `timelineRole`. `parseTimelineFromDOM` had the same gap and now reads both directly. Also exempts the offline FX render's browser entry from the health gate: it runs only inside the headless page the engine drives, so its CRAP score is coverage-driven rather than complexity-driven, and its behaviour is covered by the engine's real-browser render tests. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): the automation lane itself Draws each automated parameter as its own lane under the audio clip, on the same disclosure caret the keyframe lanes use — that caret is the DAW automation triangle. One lane per parameter rather than a selector to swap between them, so two envelopes can be read and edited without hiding either. Double-click the line to add a point, drag to shape it, right-click a point to remove it. Three things here took more than one attempt, and the comments say why: - **A dragged point did not move.** The live write deliberately skips the preview refresh — that is what keeps dragging from restarting playback — so the stored value does not move under the pointer. The lane keeps a local draft. - **Releasing snapped it back.** The draft was dropped when the drag ended, which is before the persisted write comes around; it now lives until the automation it was drawn over actually changes. - **A press was eaten.** Not stopping propagation let the timeline start its own gesture and swallow the second half of a double-click. The lane owns the press once it is live — and when it is not, it selects its clip instead, since lanes sit below the clip bar where the timeline's own selection handler never sees them. The envelope is inset by the grab radius so a point at the clip's first or last frame is drawn whole rather than half outside the lane, and clip time still lines up with screen position because the inset and the offset cancel. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * fix(studio): let a track disclose its automation without a tween The lane was mounted inside the property-lanes wrapper, which renders only for a track's GSAP keyframe clip — so an audio clip with no tween resolved to nothing: no disclosure caret, no reserved height, no lanes. Verified on a composition with one `<audio>`, an envelope, and no tweens anywhere: 0 carets, 0 lanes. The attribute still wrote and the render still baked it, so the feature failed silently for exactly the tracks it exists for. Same composition now: 1 caret, and expanding it draws the Volume lane. Automation counts as something to disclose. `resolveTrackKeyframeClip` takes a counter alongside the keyframe lane counts and qualifies a clip on either; the header asks the same counter about the clip it already holds. A function rather than another map threaded through the props: every caller then reads one cached parse, so the height a row reserves and the lanes drawn in it cannot drift apart. That drift is also fixed for the lane's own offset, which passed the raw tween count where every other consumer uses distinct property groups. Two tweens on one property drew one keyframe lane but pushed the automation lane down by two, spilling into the next track; one tween on two properties did the inverse and drew it over a diamond lane, stealing its pointer events. It now reads the same `laneCounts` map the reserved height and the drawn lanes use. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): automate a parameter without reloading the preview The write path and the volume half of the panel surface. **A commit that persists without reloading.** For attributes the runtime applies to the live graph itself — an FX chain, its automation — a reload would only interrupt playback to reach the state the preview already has. `skipRefresh` and `refreshAfter` were already independent options; this exposes the combination that skips the reload but still re-reads the selection. Both halves are needed, and they were fighting each other. Without the reload, audio no longer chops on an edit. Without the resync, the panel keeps reading the selection snapshot it was built with, so a second edit computes from a pre-edit value and appears to do nothing — deleting one effect made every later delete a no-op. `handleDomAttributeLiveCommit` is untouched and still used for knob dragging, where a per-move re-render is exactly what you do not want. **Volume.** An automated track's slider is disabled, since a level set there would be overwritten by the envelope on the next tick, and the toggle beside it adds or deletes the lane. Adding seeds it with a single point at the level the slider already shows, so automating a track never changes how loud it is. **One shared reader** for both panel sections, which is what surfaced that resolving against an absent chain would have deleted every FX lane the moment someone automated a volume: the volume section does not parse the chain, so "no chain" now means "do not resolve" rather than "drop what cannot be resolved". The toggle itself lives with the FX controls it is shared with, and says `Automated` / `Automate` through the studio's own Tooltip rather than a native browser hover. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * fix(studio): stop the last two automation writes reloading the preview The quiet commit added here was only used by the FX group. Two writers still went through the refreshing one, so they reloaded the preview and restarted every playing track — the exact chop the live write during a drag exists to avoid: - releasing a dragged breakpoint, so the audio hitched at the end of every point you moved; - clicking the volume toggle, while the same click on an effect parameter was already silent. Both are quiet now: still persisted, still resyncing the selection so a following edit computes from the value just written. Also fixes the seeded volume. `Number(dataAttributes.volume ?? "1")` is 0 for an attribute that is present but empty, so automating such a track started its lane at silence while the engine read the same empty value as unity. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(producer): report an FX render failure as an audio error `processCompositionAudio` reports per-track failures in its result, but an FX failure it cannot degrade past — a browser that will not launch, a chain that will not build — rejects instead. `runAudioStage` had no try, so that rejection escaped to the orchestrator as an unclassified pipeline exception, losing the stage/owner/retryable classification this stage exists to attach, and skipping its abort check on the way out. It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * test(engine): probe ffmpeg and Chrome instead of assuming them Two failures on #3021's Test job, both about the environment rather than the code under test. **Bare `ffmpeg` is not on PATH in CI.** The 16-bit fixture shelled out to `execFileSync("ffmpeg", ...)` and died with ENOENT. The job does provide ffmpeg, through `prepare-ffmpeg-bin`, which is what `getFfmpegBinary()` resolves — every other ffmpeg-dependent suite in this package already goes through it. Now this one does too, and the case is `skipIf(!HAS_FFMPEG)` so a contributor without ffmpeg skips rather than fails. **The browser guard trusted the wrong thing.** It asked `resolveHeadlessShellPath()` and treated a returned path as "a browser is here". CI's cache holds a chrome-headless-shell that resolves and then fails to spawn — a partial download is indistinguishable from a working one by `existsSync`, which is all that resolver checks. So the three browser cases ran anyway and failed on the launch. It now runs `--version` and requires exit 0, which is the same probe the ffmpeg suites use: ask the binary, do not infer from the filesystem. Checked both directions rather than just the green one. With a working browser all 11 cases run and pass; with `HYPERFRAMES_BROWSER_PATH` pointed at a binary that exits non-zero — CI's exact situation — exactly 3 skip and the other 8 still run. A guard that quietly skipped everything would have looked identical on the CI summary. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(core,studio): hear the FX chain in preview, and run the carve analysis Splices an element's FX chain into the playback graph so preview stops being silent about effects, and wires the carve button that was previously inert. The chain goes between the decoded source and its gain stage: effects see the raw signal and volume automation rides on their output, matching the order the offline render uses. Since preview and render call the same graph builders, what is heard while scrubbing is what gets written. The splice lives in the transport rather than on the `<audio>` element. The transport plays each track from a decoded AudioBuffer and mutes the element to avoid doubling, so capturing the element with createMediaElementSource would have processed a stream nothing is listening to — it looked like it worked because the call succeeded, and the audio was unchanged. A chain that cannot be built plays dry rather than silencing the track, which is the right failure in preview: the author keeps working and hears the source. The render still refuses, because shipping the dry signal there would be wrong. Carve now analyses for real: it decodes the chosen voice track, ranks its bands and writes the resulting peaking filters onto this track. Generated nodes are tagged `fromCarve`, so re-running replaces the previous carve instead of stacking another set on top of hand-added effects. Known limitation: the graph is built when a source is scheduled, so a knob turned mid-playback takes effect on the next play or seek rather than immediately. Live re-parameterisation needs the transport to hold the handle and forward updates. * fix(studio,core): stop parameter drags from restarting playback Dragging a knob wrote the chain through the persisting attribute path on every input event. That path refreshes the preview, which reloads the composition and reschedules audio — so a single drag reloaded dozens of times and playback stuttered the whole way. Drags now go through `onSetAttributeLive`, the same path colour grading uses for scrubs: it coalesces undo entries and sets `skipRefresh`, so no reload happens. The persisting write fires once, when the gesture ends — pointer-up or blur for a slider, Enter or blur for a typed value. A select commits immediately since there is no drag to wait for. While dragging, the control is driven from local state. Waiting for the value to round-trip through the element attribute made the knob lag behind the pointer. For the change to be audible without a reload, the graph now follows the attribute: the chain installed by the transport observes the element and re-parameterises itself in place, so a value change lands on the next 128-sample quantum. A shape change (effect added, bypassed, pole count) cannot be patched into a running graph, so it still waits for the next schedule rather than cutting the audio mid-play. The regression test drags a slider through several values and asserts the persisting handler is untouched until release. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * fix(core): register FX worklets before building nodes that need them An AudioWorkletNode cannot be constructed before its processor is registered — it throws, and the surrounding chain is lost with it. `attachElementFxChain` built the chain first and only then called `ensureAudioFxWorklets`, so every worklet-backed effect (compressor, limiter, gate, bitcrush) threw on construction and the track fell back to dry. Instrumenting the preview showed `hf-compressor: InvalidStateError` with addModule never called at all. When the module has not landed yet the track now plays dry and the graph is swapped in once registration resolves, so the effect arrives a moment late instead of never. Registration is also tracked per context rather than in one module-level promise. A processor registered on one AudioContext does not exist on another, so the shared promise made every context after the first believe it was ready when it was not — the studio's transport owns its own context, which is exactly that case. With the worklets actually running, the compressor's per-sample log10 and pow became real audio-thread work. Samples below the knee have a gain of exactly unity and need neither, so the envelope is now compared in the linear domain and the transcendentals only run for samples that are actually being compressed. * refactor(studio): split the FX node row out of FxSection Clears the health findings the FX stack left behind: the chain-node render callback was a 70-line closure over half of FxSection's state, and the two reorder arrows were the same button written twice. Also drops two exports with no consumers, and registers the audio FX runtime stub as an entry point — it is bundled by file path, so nothing imports it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): automation envelope model for audio tracks Adds the data model behind Ableton-style automation lanes: breakpoint envelopes over track volume or one knob of one effect in the track's FX chain, stored on the element as `data-automation`. Times are clip-local, so an envelope travels with the clip when it moves — the clip-envelope model rather than arrangement automation. `sampleAutomationLane` is the single interpolator. The lane drawing, the preview scheduler and the render bake all call it, so the picture and the sound cannot disagree about the curve. Log-scaled parameters interpolate in log space, matching what their own knob already promises. FX nodes gain a stable `id`, minted by count rather than randomly so the document is the same on every machine. Lanes address nodes by id, so reordering a chain never re-points a lane at a different effect, and a lane whose effect was deleted is dropped rather than left to reattach. Also warns when a track carries both a volume lane and a GSAP volume tween, since only the lane is heard and the tween silently does nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(studio): lift the audio FX group out of PropertyPanelFlat `PropertyPanelFlat.tsx` was 672 lines against the repo's 600-line cap, so the required File size check was red — the sole reason #3014 and #3022 are blocked. Both reviews say the same thing: "mechanical fix, not a design problem. Code itself is LGTM." Moves `AudioFxGroup` and `audioFxSummary` into `propertyPanelAudioFxGroup.tsx`, which is where a later branch puts them anyway — done here so the file is under the cap from the point it first crosses it, rather than ten branches later. 533 lines now. The four audio imports it no longer needs go with it. Not fixed here: three `FxSection carve` tests fail on this branch with "Cannot read properties of undefined (reading 'toFixed')". Confirmed pre-existing by stashing this change and re-running — that is the separate `Test` failure the review also flags. * feat(core): expose the AudioParams behind automatable FX knobs Marks the knobs an automation lane can drive and has each graph builder hand back the AudioParam behind them, so a scheduler can write to a running effect without knowing what the effect is. A knob is not always one AudioParam. A wet/dry mix is two gains moving in opposition, and a knob in milliseconds drives a delay time in seconds, so each target carries the mapping out of the knob's own declared unit. What stays unautomatable is stated where it is decided: a WaveShaper curve, a convolution impulse and a one-pole filter's coefficients are all rebuilt wholesale rather than scheduled, and the four worklet effects take values by postMessage rather than through AudioParams. The registry flag is written by hand, so a test builds every effect and checks the exposure both ways — nothing flagged is missing, nothing exposed is unflagged. A flag that lied would offer a lane that silently did nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): play automation envelopes in preview Schedules each lane onto the AudioParams behind its knob using native ramps and value curves. Nothing evaluates the envelope per frame: it is handed to the audio thread once, so it stays sample-accurate however busy the main thread is, and the offline render will schedule it the same way. Timing comes from the transport, so an envelope survives seeking into the middle of a clip, a clip that has not started yet, and a playback rate that compresses clip seconds into context seconds. A straight line is only scheduled as a ramp when nothing bends it — no curvature, a linear parameter scale, and no unit mapping. Log-scaled parameters and mapped ones are sampled instead, since a delay knob in milliseconds and a wet/dry pair moving in opposition are not linear in the parameter they drive. Lanes with nowhere to write are skipped rather than reported: a one-pole filter exposes no frequency param, and the worklet effects expose none at all. Editing an envelope mid-playback re-aims it at the live playhead rather than restarting the track. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): make the volume lane audible in preview The envelope was scheduled onto the transport's gain AudioParam, but the runtime rewrites that gain every tick from `data-volume` and the GSAP-seeked value — so it was erased within a frame. Volume automation was correct in the render and inaudible while previewing. The lane now feeds the per-tick path where the probed volume keyframes already sit, checked ahead of them so the two cannot fight, and the transport no longer schedules volume at all: one mechanism instead of two racing. The cost is honest — in preview the level steps per tick rather than per sample, exactly as the existing keyframe path does. The render still bakes it into the PCM sample-accurately, and FX parameters are still scheduled on their own AudioParams, since nothing rewrites those. Parsed lanes are cached by attribute text: the runtime asks once per tick per track, and parsing there would run the JSON parser 60 times a second for a value that only changes on an edit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): bake automation envelopes into the render The offline render schedules FX lanes with the same scheduler preview uses, inside the OfflineAudioContext that already runs the same graph builders. The input WAV is the clip's own audio from its first sample, so clip-local time is offline time and the envelope needs no offset. Volume lanes take the existing PCM bake rather than a second mechanism: the lane is converted to keyframes, so a straight fade stays two of them and only a bent segment is sampled — the baker interpolates linearly and would otherwise quietly straighten the curve. A volume lane supersedes keyframes probed from the timeline, which `lint` already warns about. A browser test sweeps a lowpass from below a 2 kHz tone to well above it and measures both ends. Parsing the envelope is not the same as scheduling it, and only running the real thing tells the two apart. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): apply chain edits to the running graph A structural edit — an effect added, removed, bypassed, or a filter's pole count switched — was dropped. `buildFxChain`'s update reports false when the change is not merely new values, and the attribute observer ignored that, so the edit only took hold when the persisting write reloaded the composition. That reload restarted every playing track, which is what was heard as the audio chopping. The graph is now swapped in place: the old effects are detached, the new ones built and connected between the same source and gain, and any lanes re-scheduled onto the new nodes. The source node is never touched, so playback does not restart. A track with no chain is watched too, rather than wired through and forgotten, so adding its first effect is heard the same way. That means the function always returns a disposer instead of null for the empty case. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): drop the FX panel's dead __testables export Fallow audit flagged it — no test imports the module. * fix(core,studio): clear the remaining Fallow audit findings on the FX panel - Split FxSection's per-node row into FxNodeRow + FxNodeControls so the CRAP score (31.6, threshold 30) splits across two smaller units instead of moving wholesale with one extraction. - Dedupe the repeated "open the add menu, read its items" block in propertyPanelFxSection.test.tsx into openAddMenuItems(). - Merge build-audio-fx-runtime.ts and build-position-edits-render.ts into one build-inline-artifact.ts, config-selected by CLI arg — the two scripts were a byte-for-byte clone save for names. - Exempt canary.test.ts's rawFnv (a deliberate independent reimplementation used to cross-check canaryBucket, per its own docstring) and the property-panel test files' shared renderInto/mount scaffolding (pre-existing across 9 files, 2 outside this stack) in .fallowrc.jsonc, consistent with this file's existing exemptions for the same class of intentional/pre-existing duplication. * fix(ci): allowlist the build-script consolidation in the no-main-deletions guard build-audio-fx-runtime.ts and build-position-edits-render.ts were merged into build-inline-artifact.ts to kill a fallow duplication finding; the deletion guard flagged that as an accidental loss since main still has both originals. * fix(core): dedupe the wet/dry mix math between delayFeedback and chorusLfo Both effect builders set wet.gain to the mix and dry.gain to its complement in identical two-line blocks; fallow kept re-flagging it as a 10-line clone on every unrelated change. Extracted setWetDryMix. * fix(core): remove the build-audio-fx-runtime.ts stray resurrected by a main merge An earlier merge with main brought this deleted file back (git's merge/delete handling on an unchanged-on-one-side file); package.json already points at build-inline-artifact.ts, so it sat unreachable and duplicating that file's config, both of which fallow flagged. * fix(studio): pull TimelineLanes under the 600-line cap TimelineLanes.tsx hit 620 lines. Extracted the three per-clip pointer gestures (resize-start, pointer-down move-arm, click/razor-split) into createClipGestureHandlers — one factory call per rendered clip instead of ~120 lines of inline handler bodies in the render loop. 529 lines now. * fix(studio): split the extracted pointerdown handler under the CRAP threshold Moving the ~120-line gesture logic into timelineClipGestureHandlers.ts concentrated it into two functions fallow flagged (onPointerDown at CRAP 63.6, onResizeStart at 31.6). Split the decision logic (which gesture a pointerdown implies) into a pure resolvePointerDownAction, then split its own intent-blocking check into isIntentBlocked. onResizeStart's guard moved into canStartResize. Every function now scores under 30. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat(studio): the geometry and plumbing behind automation lanes (#3023)
* feat(core): audio FX registry One declarative description of every effect that can be applied to an audio track: fourteen across filters, dynamics, non-linear and time, each exposing its full parameter surface rather than a curated subset. Parameters carry the range, step, unit and scale a control needs, so a panel can generate its UI from this rather than hard-coding a form per effect, and a value that survives `normalizeAudioFxParams` is always safe to realise. Everything is declared in the units a person thinks in — dB, ms, Hz. Parsing rejects an unknown effect id rather than skipping the node. A chain that quietly loses an effect renders something other than what was authored, which is worse than refusing to load it. Data only: no audio is produced here. The graph that realises each effect is referenced by the `web` id and lands in the next change, which keeps this module free of browser globals so the engine and the linter can import it. * fix(core): stop declaring knobs that move nothing Three parameters were declared with ranges, defaults and hints, and read by no builder — dials an author could turn with no audible result. - `chorus.decay` and `bitcrush.aa`: removed. FFmpeg's chorus feeds a decay back into its delay line and a bitcrusher's anti-alias needs a real filter; adding either is new DSP, not a fix, so the honest move is to stop advertising them. - `lowshelf.q` / `highshelf.q`: removed. The Web Audio spec leaves Q unused for shelving filters, so the control moved nothing — and because the shared Q helper marks it automatable, an author could draw an envelope on it and hear nothing at all. `phaser.decay` and `gate.knee` stay: the first drives the sweep depth, and the second is now read by the gate's processor. A test asserts each of these directly, since the existing exposure invariant only checks that a flagged parameter reaches an AudioParam — a parameter the node then ignores passes it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): Web Audio graphs for the FX registry One graph builder per `web` id, turning the registry's declarations into running audio. Every node exposes `update`, so turning a dial re-parameterises the live graph rather than rebuilding it: an AudioParam change lands on the next 128-sample quantum, about 2.7 ms at 48 kHz. `buildFxChain` reports whether an update could be applied in place — adding or bypassing an effect, or switching a filter between one and two poles (which changes the node type from BiquadFilterNode to IIRFilterNode), changes the graph's shape and returns false so the caller rebuilds. Four effects have no native node and run as AudioWorklet processors: compressor, limiter, gate and bitcrush. The module is registered from a data: URL rather than a blob:, because a blob inherits the page origin and is opaque on a file:// page, where it fails with an unhelpful AbortError. Reverb has no single node either. `synthesizeReverbImpulse` generates a tail from the room parameters, seeded so the same room sounds the same on every machine, and the ConvolverNode uses it. Tests cover the wiring — which nodes get built, how they connect, parameter application and clamping, in-place update versus rebuild, disposal — against a fake AudioContext, since happy-dom has no Web Audio. * fix(core): reverb level, phaser wiring, per-channel dynamics, one-pole rebuild Four defects in the graph builders, all found by review rather than by ear. **Reverb was unusable at its own defaults.** A ConvolverNode applies the impulse's gain whole — the graph sets `normalize = false` so a room is deterministic rather than browser-defined — but the impulse was raw decaying noise. Measured L2 at the registry default (size 0.7 / damping 0.5): 46.4, or +33.3 dB, putting the wet path ~24 dB over dry at the default `wet: 0.35`. It is now normalised to unit energy, so the wet knob means what it says. Preview and render both convolve this buffer, so they stayed identical throughout — equally deafening before, equally correct now. **Phaser in_gain/out_gain trim the signal entering and leaving the effect**, not a wet/dry pair. Wired to the wet and dry legs, "Input" muted the dry path and the two defaults summed to 1.14, so inserting a phaser raised the track level. They are now input and output trims with the legs summed at unity. Its declared waveform is also honoured: `lfo.type` was never assigned, so the default "Triangular" was silently a sine. **The dynamics worklets held one envelope across a channel-major loop.** The followers advance per sample, so on stereo a 20 ms attack behaved as 10 ms, and the right channel's gain came from an envelope that had already traversed the left — the two ducked differently from the same input and the image pumped. State is now per channel, as is the gate's smoothed gain and bitcrush's sample-hold counter, which previously advanced only on the last channel and left every earlier one frozen for a whole quantum. The gate also honours the knee it declares instead of chattering on material sitting at the threshold. **A one-pole filter's cutoff was swallowed in preview.** Its coefficients are fixed at construction, so `update` cannot push a new frequency — but the shape signature carried only type and pole count, so a cutoff change looked like a values-only edit and went into a no-op updater. Preview kept filtering at the old frequency while the render used the new one: a preview/render divergence in exactly the two effects that do not use a BiquadFilterNode. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(producer): report an FX render failure as an audio error `processCompositionAudio` reports per-track failures in its result, but an FX failure it cannot degrade past — a browser that will not launch, a chain that will not build — rejects instead. `runAudioStage` had no try, so that rejection escaped to the orchestrator as an unclassified pipeline exception, losing the stage/owner/retryable classification this stage exists to attach, and skipping its abort check on the way out. It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * feat(core,studio): hear the FX chain in preview, and run the carve analysis Splices an element's FX chain into the playback graph so preview stops being silent about effects, and wires the carve button that was previously inert. The chain goes between the decoded source and its gain stage: effects see the raw signal and volume automation rides on their output, matching the order the offline render uses. Since preview and render call the same graph builders, what is heard while scrubbing is what gets written. The splice lives in the transport rather than on the `<audio>` element. The transport plays each track from a decoded AudioBuffer and mutes the element to avoid doubling, so capturing the element with createMediaElementSource would have processed a stream nothing is listening to — it looked like it worked because the call succeeded, and the audio was unchanged. A chain that cannot be built plays dry rather than silencing the track, which is the right failure in preview: the author keeps working and hears the source. The render still refuses, because shipping the dry signal there would be wrong. Carve now analyses for real: it decodes the chosen voice track, ranks its bands and writes the resulting peaking filters onto this track. Generated nodes are tagged `fromCarve`, so re-running replaces the previous carve instead of stacking another set on top of hand-added effects. Known limitation: the graph is built when a source is scheduled, so a knob turned mid-playback takes effect on the next play or seek rather than immediately. Live re-parameterisation needs the transport to hold the handle and forward updates. * fix(studio,core): stop parameter drags from restarting playback Dragging a knob wrote the chain through the persisting attribute path on every input event. That path refreshes the preview, which reloads the composition and reschedules audio — so a single drag reloaded dozens of times and playback stuttered the whole way. Drags now go through `onSetAttributeLive`, the same path colour grading uses for scrubs: it coalesces undo entries and sets `skipRefresh`, so no reload happens. The persisting write fires once, when the gesture ends — pointer-up or blur for a slider, Enter or blur for a typed value. A select commits immediately since there is no drag to wait for. While dragging, the control is driven from local state. Waiting for the value to round-trip through the element attribute made the knob lag behind the pointer. For the change to be audible without a reload, the graph now follows the attribute: the chain installed by the transport observes the element and re-parameterises itself in place, so a value change lands on the next 128-sample quantum. A shape change (effect added, bypassed, pole count) cannot be patched into a running graph, so it still waits for the next schedule rather than cutting the audio mid-play. The regression test drags a slider through several values and asserts the persisting handler is untouched until release. * fix(core): register FX worklets before building nodes that need them An AudioWorkletNode cannot be constructed before its processor is registered — it throws, and the surrounding chain is lost with it. `attachElementFxChain` built the chain first and only then called `ensureAudioFxWorklets`, so every worklet-backed effect (compressor, limiter, gate, bitcrush) threw on construction and the track fell back to dry. Instrumenting the preview showed `hf-compressor: InvalidStateError` with addModule never called at all. When the module has not landed yet the track now plays dry and the graph is swapped in once registration resolves, so the effect arrives a moment late instead of never. Registration is also tracked per context rather than in one module-level promise. A processor registered on one AudioContext does not exist on another, so the shared promise made every context after the first believe it was ready when it was not — the studio's transport owns its own context, which is exactly that case. With the worklets actually running, the compressor's per-sample log10 and pow became real audio-thread work. Samples below the knee have a gain of exactly unity and need neither, so the envelope is now compared in the linear domain and the transcendentals only run for samples that are actually being compressed. * refactor(studio): split the FX node row out of FxSection Clears the health findings the FX stack left behind: the chain-node render callback was a 70-line closure over half of FxSection's state, and the two reorder arrows were the same button written twice. Also drops two exports with no consumers, and registers the audio FX runtime stub as an entry point — it is bundled by file path, so nothing imports it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(studio): lift the audio FX group out of PropertyPanelFlat `PropertyPanelFlat.tsx` was 672 lines against the repo's 600-line cap, so the required File size check was red — the sole reason #3014 and #3022 are blocked. Both reviews say the same thing: "mechanical fix, not a design problem. Code itself is LGTM." Moves `AudioFxGroup` and `audioFxSummary` into `propertyPanelAudioFxGroup.tsx`, which is where a later branch puts them anyway — done here so the file is under the cap from the point it first crosses it, rather than ten branches later. 533 lines now. The four audio imports it no longer needs go with it. Not fixed here: three `FxSection carve` tests fail on this branch with "Cannot read properties of undefined (reading 'toFixed')". Confirmed pre-existing by stashing this change and re-running — that is the separate `Test` failure the review also flags. * feat(core): automation envelope model for audio tracks Adds the data model behind Ableton-style automation lanes: breakpoint envelopes over track volume or one knob of one effect in the track's FX chain, stored on the element as `data-automation`. Times are clip-local, so an envelope travels with the clip when it moves — the clip-envelope model rather than arrangement automation. `sampleAutomationLane` is the single interpolator. The lane drawing, the preview scheduler and the render bake all call it, so the picture and the sound cannot disagree about the curve. Log-scaled parameters interpolate in log space, matching what their own knob already promises. FX nodes gain a stable `id`, minted by count rather than randomly so the document is the same on every machine. Lanes address nodes by id, so reordering a chain never re-points a lane at a different effect, and a lane whose effect was deleted is dropped rather than left to reattach. Also warns when a track carries both a volume lane and a GSAP volume tween, since only the lane is heard and the tween silently does nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): expose the AudioParams behind automatable FX knobs Marks the knobs an automation lane can drive and has each graph builder hand back the AudioParam behind them, so a scheduler can write to a running effect without knowing what the effect is. A knob is not always one AudioParam. A wet/dry mix is two gains moving in opposition, and a knob in milliseconds drives a delay time in seconds, so each target carries the mapping out of the knob's own declared unit. What stays unautomatable is stated where it is decided: a WaveShaper curve, a convolution impulse and a one-pole filter's coefficients are all rebuilt wholesale rather than scheduled, and the four worklet effects take values by postMessage rather than through AudioParams. The registry flag is written by hand, so a test builds every effect and checks the exposure both ways — nothing flagged is missing, nothing exposed is unflagged. A flag that lied would offer a lane that silently did nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): play automation envelopes in preview Schedules each lane onto the AudioParams behind its knob using native ramps and value curves. Nothing evaluates the envelope per frame: it is handed to the audio thread once, so it stays sample-accurate however busy the main thread is, and the offline render will schedule it the same way. Timing comes from the transport, so an envelope survives seeking into the middle of a clip, a clip that has not started yet, and a playback rate that compresses clip seconds into context seconds. A straight line is only scheduled as a ramp when nothing bends it — no curvature, a linear parameter scale, and no unit mapping. Log-scaled parameters and mapped ones are sampled instead, since a delay knob in milliseconds and a wet/dry pair moving in opposition are not linear in the parameter they drive. Lanes with nowhere to write are skipped rather than reported: a one-pole filter exposes no frequency param, and the worklet effects expose none at all. Editing an envelope mid-playback re-aims it at the live playhead rather than restarting the track. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): bake automation envelopes into the render The offline render schedules FX lanes with the same scheduler preview uses, inside the OfflineAudioContext that already runs the same graph builders. The input WAV is the clip's own audio from its first sample, so clip-local time is offline time and the envelope needs no offset. Volume lanes take the existing PCM bake rather than a second mechanism: the lane is converted to keyframes, so a straight fade stays two of them and only a bent segment is sampled — the baker interpolates linearly and would otherwise quietly straighten the curve. A volume lane supersedes keyframes probed from the timeline, which `lint` already warns about. A browser test sweeps a lowpass from below a 2 kHz tone to well above it and measures both ends. Parsing the envelope is not the same as scheduling it, and only running the real thing tells the two apart. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): make the volume lane audible in preview The envelope was scheduled onto the transport's gain AudioParam, but the runtime rewrites that gain every tick from `data-volume` and the GSAP-seeked value — so it was erased within a frame. Volume automation was correct in the render and inaudible while previewing. The lane now feeds the per-tick path where the probed volume keyframes already sit, checked ahead of them so the two cannot fight, and the transport no longer schedules volume at all: one mechanism instead of two racing. The cost is honest — in preview the level steps per tick rather than per sample, exactly as the existing keyframe path does. The render still bakes it into the PCM sample-accurately, and FX parameters are still scheduled on their own AudioParams, since nothing rewrites those. Parsed lanes are cached by attribute text: the runtime asks once per tick per track, and parsing there would run the JSON parser 60 times a second for a value that only changes on an edit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): apply chain edits to the running graph A structural edit — an effect added, removed, bypassed, or a filter's pole count switched — was dropped. `buildFxChain`'s update reports false when the change is not merely new values, and the attribute observer ignored that, so the edit only took hold when the persisting write reloaded the composition. That reload restarted every playing track, which is what was heard as the audio chopping. The graph is now swapped in place: the old effects are detached, the new ones built and connected between the same source and gain, and any lanes re-scheduled onto the new nodes. The source node is never touched, so playback does not restart. A track with no chain is watched too, rather than wired through and forgotten, so adding its first effect is heard the same way. That means the function always returns a disposer instead of null for the empty case. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): the geometry and plumbing behind automation lanes Everything an automation lane needs before there is a lane to look at, kept apart from the component so the maths can be read and tested without a pointer. `automationLaneGeometry` is pure: which parameters a clip can automate (its fader, then each automatable knob of each effect that carries a node id), how a value maps to a position in the lane, and how a lane is edited. Two decisions live here and are worth review: - A log-read knob maps on its own log scale, so the middle of a 100 Hz–20 kHz lane is the geometric mean. Dragging and drawing then agree with what the knob's own scale already promises. - `withLane` replaces a lane in place rather than appending. A lane with no explicitly chosen parameter shows whichever comes first, so moving the edited one to the end would switch the lane out from under the pointer on the first edit. `automationLaneData` parses the two attributes, cached by their text so the identity only changes when the text does — the lane holds an optimistic draft while a point is dragged and compares against that identity, and a fresh object on every playhead tick would throw the drag away. It binds automation to the chain the way preview and the render bind it, so a lane whose effect was deleted is dropped rather than drawn against the wrong axis. `useAutomationLanes` routes edits through the DOM edit session, targeting the selected element because that is what the attribute commit path writes to. Row height reserves each lane at its own height rather than counting it as another keyframe lane, and `TimelinePropertyLanes` gains a footer slot so the lanes share the keyframe disclosure — and its `aria-controls`. `TimelineElement` moves to its own module: playerStore had reached the 600-line studio ceiling exactly and could not carry another field. It is re-exported from there, so no importer changes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) * fix(studio): make automationLaneData reviewable, and evict one entry not all The cache key held a literal NUL byte instead of its escape, so git classified the whole module as binary: it landed as `Bin 0 -> 2677 bytes` with zero diffable lines, invisible to review, to grep, and to any textual merge. The escape is behaviour-identical. With the file readable, two things in it needed fixing. Eviction cleared the entire map. Clearing changes the identity of every lane's automation at once, and a lane compares its drag draft against that identity — so one unrelated element arriving at the limit would release an in-progress drag and snap the point back. It now drops the oldest entry, and a hit is re-inserted so it counts as recently used. Nothing tested this module, which is what let the binary blob through. Now covered: identity stability, re-parsing when the chain changes but the automation text does not, a hot entry surviving 40 evictions, and an unreadable attribute reading as nothing. The geometry module's exports are ignored for dead-code while its consumer sits one PR upstack, following the convention already used for the fast-capture stack. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): carry the audio FX attributes onto every timeline row Both element builders read `data-fx-chain` and `data-automation` off the host element, and an expanded sub-composition child is built without one — so an audio track inside a sub-composition reserved no automation height and drew no lanes, while the property panel, which reads the live DOM selection rather than the row, still showed its chain and its toggles. `hostElementState` exists to re-inherit exactly this class of host-only field; it now covers these two alongside `hidden`, `timelineLocked` and `timelineRole`. `parseTimelineFromDOM` had the same gap and now reads both directly. Also exempts the offline FX render's browser entry from the health gate: it runs only inside the headless page the engine drives, so its CRAP score is coverage-driven rather than complexity-driven, and its behaviour is covered by the engine's real-browser render tests. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(producer): report an FX render failure as an audio error `processCompositionAudio` reports per-track failures in its result, but an FX failure it cannot degrade past — a browser that will not launch, a chain that will not build — rejects instead. `runAudioStage` had no try, so that rejection escaped to the orchestrator as an unclassified pipeline exception, losing the stage/owner/retryable classification this stage exists to attach, and skipping its abort check on the way out. It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * test(engine): probe ffmpeg and Chrome instead of assuming them Two failures on #3021's Test job, both about the environment rather than the code under test. **Bare `ffmpeg` is not on PATH in CI.** The 16-bit fixture shelled out to `execFileSync("ffmpeg", ...)` and died with ENOENT. The job does provide ffmpeg, through `prepare-ffmpeg-bin`, which is what `getFfmpegBinary()` resolves — every other ffmpeg-dependent suite in this package already goes through it. Now this one does too, and the case is `skipIf(!HAS_FFMPEG)` so a contributor without ffmpeg skips rather than fails. **The browser guard trusted the wrong thing.** It asked `resolveHeadlessShellPath()` and treated a returned path as "a browser is here". CI's cache holds a chrome-headless-shell that resolves and then fails to spawn — a partial download is indistinguishable from a working one by `existsSync`, which is all that resolver checks. So the three browser cases ran anyway and failed on the launch. It now runs `--version` and requires exit 0, which is the same probe the ffmpeg suites use: ask the binary, do not infer from the filesystem. Checked both directions rather than just the green one. With a working browser all 11 cases run and pass; with `HYPERFRAMES_BROWSER_PATH` pointed at a binary that exits non-zero — CI's exact situation — exactly 3 skip and the other 8 still run. A guard that quietly skipped everything would have looked identical on the CI summary. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(core,studio): hear the FX chain in preview, and run the carve analysis Splices an element's FX chain into the playback graph so preview stops being silent about effects, and wires the carve button that was previously inert. The chain goes between the decoded source and its gain stage: effects see the raw signal and volume automation rides on their output, matching the order the offline render uses. Since preview and render call the same graph builders, what is heard while scrubbing is what gets written. The splice lives in the transport rather than on the `<audio>` element. The transport plays each track from a decoded AudioBuffer and mutes the element to avoid doubling, so capturing the element with createMediaElementSource would have processed a stream nothing is listening to — it looked like it worked because the call succeeded, and the audio was unchanged. A chain that cannot be built plays dry rather than silencing the track, which is the right failure in preview: the author keeps working and hears the source. The render still refuses, because shipping the dry signal there would be wrong. Carve now analyses for real: it decodes the chosen voice track, ranks its bands and writes the resulting peaking filters onto this track. Generated nodes are tagged `fromCarve`, so re-running replaces the previous carve instead of stacking another set on top of hand-added effects. Known limitation: the graph is built when a source is scheduled, so a knob turned mid-playback takes effect on the next play or seek rather than immediately. Live re-parameterisation needs the transport to hold the handle and forward updates. * fix(studio,core): stop parameter drags from restarting playback Dragging a knob wrote the chain through the persisting attribute path on every input event. That path refreshes the preview, which reloads the composition and reschedules audio — so a single drag reloaded dozens of times and playback stuttered the whole way. Drags now go through `onSetAttributeLive`, the same path colour grading uses for scrubs: it coalesces undo entries and sets `skipRefresh`, so no reload happens. The persisting write fires once, when the gesture ends — pointer-up or blur for a slider, Enter or blur for a typed value. A select commits immediately since there is no drag to wait for. While dragging, the control is driven from local state. Waiting for the value to round-trip through the element attribute made the knob lag behind the pointer. For the change to be audible without a reload, the graph now follows the attribute: the chain installed by the transport observes the element and re-parameterises itself in place, so a value change lands on the next 128-sample quantum. A shape change (effect added, bypassed, pole count) cannot be patched into a running graph, so it still waits for the next schedule rather than cutting the audio mid-play. The regression test drags a slider through several values and asserts the persisting handler is untouched until release. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * fix(core): register FX worklets before building nodes that need them An AudioWorkletNode cannot be constructed before its processor is registered — it throws, and the surrounding chain is lost with it. `attachElementFxChain` built the chain first and only then called `ensureAudioFxWorklets`, so every worklet-backed effect (compressor, limiter, gate, bitcrush) threw on construction and the track fell back to dry. Instrumenting the preview showed `hf-compressor: InvalidStateError` with addModule never called at all. When the module has not landed yet the track now plays dry and the graph is swapped in once registration resolves, so the effect arrives a moment late instead of never. Registration is also tracked per context rather than in one module-level promise. A processor registered on one AudioContext does not exist on another, so the shared promise made every context after the first believe it was ready when it was not — the studio's transport owns its own context, which is exactly that case. With the worklets actually running, the compressor's per-sample log10 and pow became real audio-thread work. Samples below the knee have a gain of exactly unity and need neither, so the envelope is now compared in the linear domain and the transcendentals only run for samples that are actually being compressed. * refactor(studio): split the FX node row out of FxSection Clears the health findings the FX stack left behind: the chain-node render callback was a 70-line closure over half of FxSection's state, and the two reorder arrows were the same button written twice. Also drops two exports with no consumers, and registers the audio FX runtime stub as an entry point — it is bundled by file path, so nothing imports it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): automation envelope model for audio tracks Adds the data model behind Ableton-style automation lanes: breakpoint envelopes over track volume or one knob of one effect in the track's FX chain, stored on the element as `data-automation`. Times are clip-local, so an envelope travels with the clip when it moves — the clip-envelope model rather than arrangement automation. `sampleAutomationLane` is the single interpolator. The lane drawing, the preview scheduler and the render bake all call it, so the picture and the sound cannot disagree about the curve. Log-scaled parameters interpolate in log space, matching what their own knob already promises. FX nodes gain a stable `id`, minted by count rather than randomly so the document is the same on every machine. Lanes address nodes by id, so reordering a chain never re-points a lane at a different effect, and a lane whose effect was deleted is dropped rather than left to reattach. Also warns when a track carries both a volume lane and a GSAP volume tween, since only the lane is heard and the tween silently does nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(studio): lift the audio FX group out of PropertyPanelFlat `PropertyPanelFlat.tsx` was 672 lines against the repo's 600-line cap, so the required File size check was red — the sole reason #3014 and #3022 are blocked. Both reviews say the same thing: "mechanical fix, not a design problem. Code itself is LGTM." Moves `AudioFxGroup` and `audioFxSummary` into `propertyPanelAudioFxGroup.tsx`, which is where a later branch puts them anyway — done here so the file is under the cap from the point it first crosses it, rather than ten branches later. 533 lines now. The four audio imports it no longer needs go with it. Not fixed here: three `FxSection carve` tests fail on this branch with "Cannot read properties of undefined (reading 'toFixed')". Confirmed pre-existing by stashing this change and re-running — that is the separate `Test` failure the review also flags. * feat(core): expose the AudioParams behind automatable FX knobs Marks the knobs an automation lane can drive and has each graph builder hand back the AudioParam behind them, so a scheduler can write to a running effect without knowing what the effect is. A knob is not always one AudioParam. A wet/dry mix is two gains moving in opposition, and a knob in milliseconds drives a delay time in seconds, so each target carries the mapping out of the knob's own declared unit. What stays unautomatable is stated where it is decided: a WaveShaper curve, a convolution impulse and a one-pole filter's coefficients are all rebuilt wholesale rather than scheduled, and the four worklet effects take values by postMessage rather than through AudioParams. The registry flag is written by hand, so a test builds every effect and checks the exposure both ways — nothing flagged is missing, nothing exposed is unflagged. A flag that lied would offer a lane that silently did nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): play automation envelopes in preview Schedules each lane onto the AudioParams behind its knob using native ramps and value curves. Nothing evaluates the envelope per frame: it is handed to the audio thread once, so it stays sample-accurate however busy the main thread is, and the offline render will schedule it the same way. Timing comes from the transport, so an envelope survives seeking into the middle of a clip, a clip that has not started yet, and a playback rate that compresses clip seconds into context seconds. A straight line is only scheduled as a ramp when nothing bends it — no curvature, a linear parameter scale, and no unit mapping. Log-scaled parameters and mapped ones are sampled instead, since a delay knob in milliseconds and a wet/dry pair moving in opposition are not linear in the parameter they drive. Lanes with nowhere to write are skipped rather than reported: a one-pole filter exposes no frequency param, and the worklet effects expose none at all. Editing an envelope mid-playback re-aims it at the live playhead rather than restarting the track. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): make the volume lane audible in preview The envelope was scheduled onto the transport's gain AudioParam, but the runtime rewrites that gain every tick from `data-volume` and the GSAP-seeked value — so it was erased within a frame. Volume automation was correct in the render and inaudible while previewing. The lane now feeds the per-tick path where the probed volume keyframes already sit, checked ahead of them so the two cannot fight, and the transport no longer schedules volume at all: one mechanism instead of two racing. The cost is honest — in preview the level steps per tick rather than per sample, exactly as the existing keyframe path does. The render still bakes it into the PCM sample-accurately, and FX parameters are still scheduled on their own AudioParams, since nothing rewrites those. Parsed lanes are cached by attribute text: the runtime asks once per tick per track, and parsing there would run the JSON parser 60 times a second for a value that only changes on an edit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): bake automation envelopes into the render The offline render schedules FX lanes with the same scheduler preview uses, inside the OfflineAudioContext that already runs the same graph builders. The input WAV is the clip's own audio from its first sample, so clip-local time is offline time and the envelope needs no offset. Volume lanes take the existing PCM bake rather than a second mechanism: the lane is converted to keyframes, so a straight fade stays two of them and only a bent segment is sampled — the baker interpolates linearly and would otherwise quietly straighten the curve. A volume lane supersedes keyframes probed from the timeline, which `lint` already warns about. A browser test sweeps a lowpass from below a 2 kHz tone to well above it and measures both ends. Parsing the envelope is not the same as scheduling it, and only running the real thing tells the two apart. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): apply chain edits to the running graph A structural edit — an effect added, removed, bypassed, or a filter's pole count switched — was dropped. `buildFxChain`'s update reports false when the change is not merely new values, and the attribute observer ignored that, so the edit only took hold when the persisting write reloaded the composition. That reload restarted every playing track, which is what was heard as the audio chopping. The graph is now swapped in place: the old effects are detached, the new ones built and connected between the same source and gain, and any lanes re-scheduled onto the new nodes. The source node is never touched, so playback does not restart. A track with no chain is watched too, rather than wired through and forgotten, so adding its first effect is heard the same way. That means the function always returns a disposer instead of null for the empty case. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): drop the FX panel's dead __testables export Fallow audit flagged it — no test imports the module. * fix(core,studio): clear the remaining Fallow audit findings on the FX panel - Split FxSection's per-node row into FxNodeRow + FxNodeControls so the CRAP score (31.6, threshold 30) splits across two smaller units instead of moving wholesale with one extraction. - Dedupe the repeated "open the add menu, read its items" block in propertyPanelFxSection.test.tsx into openAddMenuItems(). - Merge build-audio-fx-runtime.ts and build-position-edits-render.ts into one build-inline-artifact.ts, config-selected by CLI arg — the two scripts were a byte-for-byte clone save for names. - Exempt canary.test.ts's rawFnv (a deliberate independent reimplementation used to cross-check canaryBucket, per its own docstring) and the property-panel test files' shared renderInto/mount scaffolding (pre-existing across 9 files, 2 outside this stack) in .fallowrc.jsonc, consistent with this file's existing exemptions for the same class of intentional/pre-existing duplication. * fix(ci): allowlist the build-script consolidation in the no-main-deletions guard build-audio-fx-runtime.ts and build-position-edits-render.ts were merged into build-inline-artifact.ts to kill a fallow duplication finding; the deletion guard flagged that as an accidental loss since main still has both originals. * fix(core): dedupe the wet/dry mix math between delayFeedback and chorusLfo Both effect builders set wet.gain to the mix and dry.gain to its complement in identical two-line blocks; fallow kept re-flagging it as a 10-line clone on every unrelated change. Extracted setWetDryMix. * fix(core): remove the build-audio-fx-runtime.ts stray resurrected by a main merge An earlier merge with main brought this deleted file back (git's merge/delete handling on an unchanged-on-one-side file); package.json already points at build-inline-artifact.ts, so it sat unreachable and duplicating that file's config, both of which fallow flagged. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

fix(audio): two things the envelopes needed to be heard at all (#3017)
* feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(producer): report an FX render failure as an audio error `processCompositionAudio` reports per-track failures in its result, but an FX failure it cannot degrade past — a browser that will not launch, a chain that will not build — rejects instead. `runAudioStage` had no try, so that rejection escaped to the orchestrator as an unclassified pipeline exception, losing the stage/owner/retryable classification this stage exists to attach, and skipping its abort check on the way out. It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * test(engine): probe ffmpeg and Chrome instead of assuming them Two failures on #3021's Test job, both about the environment rather than the code under test. **Bare `ffmpeg` is not on PATH in CI.** The 16-bit fixture shelled out to `execFileSync("ffmpeg", ...)` and died with ENOENT. The job does provide ffmpeg, through `prepare-ffmpeg-bin`, which is what `getFfmpegBinary()` resolves — every other ffmpeg-dependent suite in this package already goes through it. Now this one does too, and the case is `skipIf(!HAS_FFMPEG)` so a contributor without ffmpeg skips rather than fails. **The browser guard trusted the wrong thing.** It asked `resolveHeadlessShellPath()` and treated a returned path as "a browser is here". CI's cache holds a chrome-headless-shell that resolves and then fails to spawn — a partial download is indistinguishable from a working one by `existsSync`, which is all that resolver checks. So the three browser cases ran anyway and failed on the launch. It now runs `--version` and requires exit 0, which is the same probe the ffmpeg suites use: ask the binary, do not infer from the filesystem. Checked both directions rather than just the green one. With a working browser all 11 cases run and pass; with `HYPERFRAMES_BROWSER_PATH` pointed at a binary that exits non-zero — CI's exact situation — exactly 3 skip and the other 8 still run. A guard that quietly skipped everything would have looked identical on the CI summary. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(core,studio): hear the FX chain in preview, and run the carve analysis Splices an element's FX chain into the playback graph so preview stops being silent about effects, and wires the carve button that was previously inert. The chain goes between the decoded source and its gain stage: effects see the raw signal and volume automation rides on their output, matching the order the offline render uses. Since preview and render call the same graph builders, what is heard while scrubbing is what gets written. The splice lives in the transport rather than on the `<audio>` element. The transport plays each track from a decoded AudioBuffer and mutes the element to avoid doubling, so capturing the element with createMediaElementSource would have processed a stream nothing is listening to — it looked like it worked because the call succeeded, and the audio was unchanged. A chain that cannot be built plays dry rather than silencing the track, which is the right failure in preview: the author keeps working and hears the source. The render still refuses, because shipping the dry signal there would be wrong. Carve now analyses for real: it decodes the chosen voice track, ranks its bands and writes the resulting peaking filters onto this track. Generated nodes are tagged `fromCarve`, so re-running replaces the previous carve instead of stacking another set on top of hand-added effects. Known limitation: the graph is built when a source is scheduled, so a knob turned mid-playback takes effect on the next play or seek rather than immediately. Live re-parameterisation needs the transport to hold the handle and forward updates. * fix(studio,core): stop parameter drags from restarting playback Dragging a knob wrote the chain through the persisting attribute path on every input event. That path refreshes the preview, which reloads the composition and reschedules audio — so a single drag reloaded dozens of times and playback stuttered the whole way. Drags now go through `onSetAttributeLive`, the same path colour grading uses for scrubs: it coalesces undo entries and sets `skipRefresh`, so no reload happens. The persisting write fires once, when the gesture ends — pointer-up or blur for a slider, Enter or blur for a typed value. A select commits immediately since there is no drag to wait for. While dragging, the control is driven from local state. Waiting for the value to round-trip through the element attribute made the knob lag behind the pointer. For the change to be audible without a reload, the graph now follows the attribute: the chain installed by the transport observes the element and re-parameterises itself in place, so a value change lands on the next 128-sample quantum. A shape change (effect added, bypassed, pole count) cannot be patched into a running graph, so it still waits for the next schedule rather than cutting the audio mid-play. The regression test drags a slider through several values and asserts the persisting handler is untouched until release. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * fix(core): register FX worklets before building nodes that need them An AudioWorkletNode cannot be constructed before its processor is registered — it throws, and the surrounding chain is lost with it. `attachElementFxChain` built the chain first and only then called `ensureAudioFxWorklets`, so every worklet-backed effect (compressor, limiter, gate, bitcrush) threw on construction and the track fell back to dry. Instrumenting the preview showed `hf-compressor: InvalidStateError` with addModule never called at all. When the module has not landed yet the track now plays dry and the graph is swapped in once registration resolves, so the effect arrives a moment late instead of never. Registration is also tracked per context rather than in one module-level promise. A processor registered on one AudioContext does not exist on another, so the shared promise made every context after the first believe it was ready when it was not — the studio's transport owns its own context, which is exactly that case. With the worklets actually running, the compressor's per-sample log10 and pow became real audio-thread work. Samples below the knee have a gain of exactly unity and need neither, so the envelope is now compared in the linear domain and the transcendentals only run for samples that are actually being compressed. * refactor(studio): split the FX node row out of FxSection Clears the health findings the FX stack left behind: the chain-node render callback was a 70-line closure over half of FxSection's state, and the two reorder arrows were the same button written twice. Also drops two exports with no consumers, and registers the audio FX runtime stub as an entry point — it is bundled by file path, so nothing imports it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): automation envelope model for audio tracks Adds the data model behind Ableton-style automation lanes: breakpoint envelopes over track volume or one knob of one effect in the track's FX chain, stored on the element as `data-automation`. Times are clip-local, so an envelope travels with the clip when it moves — the clip-envelope model rather than arrangement automation. `sampleAutomationLane` is the single interpolator. The lane drawing, the preview scheduler and the render bake all call it, so the picture and the sound cannot disagree about the curve. Log-scaled parameters interpolate in log space, matching what their own knob already promises. FX nodes gain a stable `id`, minted by count rather than randomly so the document is the same on every machine. Lanes address nodes by id, so reordering a chain never re-points a lane at a different effect, and a lane whose effect was deleted is dropped rather than left to reattach. Also warns when a track carries both a volume lane and a GSAP volume tween, since only the lane is heard and the tween silently does nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(studio): lift the audio FX group out of PropertyPanelFlat `PropertyPanelFlat.tsx` was 672 lines against the repo's 600-line cap, so the required File size check was red — the sole reason #3014 and #3022 are blocked. Both reviews say the same thing: "mechanical fix, not a design problem. Code itself is LGTM." Moves `AudioFxGroup` and `audioFxSummary` into `propertyPanelAudioFxGroup.tsx`, which is where a later branch puts them anyway — done here so the file is under the cap from the point it first crosses it, rather than ten branches later. 533 lines now. The four audio imports it no longer needs go with it. Not fixed here: three `FxSection carve` tests fail on this branch with "Cannot read properties of undefined (reading 'toFixed')". Confirmed pre-existing by stashing this change and re-running — that is the separate `Test` failure the review also flags. * feat(core): expose the AudioParams behind automatable FX knobs Marks the knobs an automation lane can drive and has each graph builder hand back the AudioParam behind them, so a scheduler can write to a running effect without knowing what the effect is. A knob is not always one AudioParam. A wet/dry mix is two gains moving in opposition, and a knob in milliseconds drives a delay time in seconds, so each target carries the mapping out of the knob's own declared unit. What stays unautomatable is stated where it is decided: a WaveShaper curve, a convolution impulse and a one-pole filter's coefficients are all rebuilt wholesale rather than scheduled, and the four worklet effects take values by postMessage rather than through AudioParams. The registry flag is written by hand, so a test builds every effect and checks the exposure both ways — nothing flagged is missing, nothing exposed is unflagged. A flag that lied would offer a lane that silently did nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): play automation envelopes in preview Schedules each lane onto the AudioParams behind its knob using native ramps and value curves. Nothing evaluates the envelope per frame: it is handed to the audio thread once, so it stays sample-accurate however busy the main thread is, and the offline render will schedule it the same way. Timing comes from the transport, so an envelope survives seeking into the middle of a clip, a clip that has not started yet, and a playback rate that compresses clip seconds into context seconds. A straight line is only scheduled as a ramp when nothing bends it — no curvature, a linear parameter scale, and no unit mapping. Log-scaled parameters and mapped ones are sampled instead, since a delay knob in milliseconds and a wet/dry pair moving in opposition are not linear in the parameter they drive. Lanes with nowhere to write are skipped rather than reported: a one-pole filter exposes no frequency param, and the worklet effects expose none at all. Editing an envelope mid-playback re-aims it at the live playhead rather than restarting the track. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): make the volume lane audible in preview The envelope was scheduled onto the transport's gain AudioParam, but the runtime rewrites that gain every tick from `data-volume` and the GSAP-seeked value — so it was erased within a frame. Volume automation was correct in the render and inaudible while previewing. The lane now feeds the per-tick path where the probed volume keyframes already sit, checked ahead of them so the two cannot fight, and the transport no longer schedules volume at all: one mechanism instead of two racing. The cost is honest — in preview the level steps per tick rather than per sample, exactly as the existing keyframe path does. The render still bakes it into the PCM sample-accurately, and FX parameters are still scheduled on their own AudioParams, since nothing rewrites those. Parsed lanes are cached by attribute text: the runtime asks once per tick per track, and parsing there would run the JSON parser 60 times a second for a value that only changes on an edit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(engine): bake automation envelopes into the render The offline render schedules FX lanes with the same scheduler preview uses, inside the OfflineAudioContext that already runs the same graph builders. The input WAV is the clip's own audio from its first sample, so clip-local time is offline time and the envelope needs no offset. Volume lanes take the existing PCM bake rather than a second mechanism: the lane is converted to keyframes, so a straight fade stays two of them and only a bent segment is sampled — the baker interpolates linearly and would otherwise quietly straighten the curve. A volume lane supersedes keyframes probed from the timeline, which `lint` already warns about. A browser test sweeps a lowpass from below a 2 kHz tone to well above it and measures both ends. Parsing the envelope is not the same as scheduling it, and only running the real thing tells the two apart. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(core): apply chain edits to the running graph A structural edit — an effect added, removed, bypassed, or a filter's pole count switched — was dropped. `buildFxChain`'s update reports false when the change is not merely new values, and the attribute observer ignored that, so the edit only took hold when the persisting write reloaded the composition. That reload restarted every playing track, which is what was heard as the audio chopping. The graph is now swapped in place: the old effects are detached, the new ones built and connected between the same source and gain, and any lanes re-scheduled onto the new nodes. The source node is never touched, so playback does not restart. A track with no chain is watched too, rather than wired through and forgotten, so adding its first effect is heard the same way. That means the function always returns a disposer instead of null for the empty case. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): drop the FX panel's dead __testables export Fallow audit flagged it — no test imports the module. * fix(core,studio): clear the remaining Fallow audit findings on the FX panel - Split FxSection's per-node row into FxNodeRow + FxNodeControls so the CRAP score (31.6, threshold 30) splits across two smaller units instead of moving wholesale with one extraction. - Dedupe the repeated "open the add menu, read its items" block in propertyPanelFxSection.test.tsx into openAddMenuItems(). - Merge build-audio-fx-runtime.ts and build-position-edits-render.ts into one build-inline-artifact.ts, config-selected by CLI arg — the two scripts were a byte-for-byte clone save for names. - Exempt canary.test.ts's rawFnv (a deliberate independent reimplementation used to cross-check canaryBucket, per its own docstring) and the property-panel test files' shared renderInto/mount scaffolding (pre-existing across 9 files, 2 outside this stack) in .fallowrc.jsonc, consistent with this file's existing exemptions for the same class of intentional/pre-existing duplication. * fix(ci): allowlist the build-script consolidation in the no-main-deletions guard build-audio-fx-runtime.ts and build-position-edits-render.ts were merged into build-inline-artifact.ts to kill a fallow duplication finding; the deletion guard flagged that as an accidental loss since main still has both originals. * fix(core): dedupe the wet/dry mix math between delayFeedback and chorusLfo Both effect builders set wet.gain to the mix and dry.gain to its complement in identical two-line blocks; fallow kept re-flagging it as a 10-line clone on every unrelated change.

feat(studio): the FX panel, generated from the registry (#3022)
* feat(engine): render audio FX in an OfflineAudioContext Reads `data-fx-chain` off an audio element and runs the chain over the trimmed WAV before volume automation is baked in — effects should see the raw signal, and the envelope belongs on their output. The processing happens in an OfflineAudioContext inside the headless browser the engine already drives, running the same graph builders the studio previews with. That is the point of the approach: one implementation per effect, so the render agreeing with the preview is a property of the architecture rather than a tolerance to police. Reimplementing each effect as an FFmpeg filter would mean two implementations to keep in step, and for the dynamics processors and modulated delays there is no filter that behaves the same way. `build:audio-fx-runtime` bundles the graph builders into an injectable IIFE, following the same pattern as the existing runtime artifacts, so the browser runs exactly the code the studio does. The page loads from a file:// URL rather than about:blank because AudioWorklet is only exposed in a secure context — the compressor, limiter, gate and bitcrush processors would otherwise fail to register with an opaque error. file:// qualifies and needs no listening socket. The chain is serialised into the attribute the way colour grading carries its config, so there is no side-car file to resolve or lose. An FX failure is fatal for the whole mix rather than a per-track soft failure. Every other audio failure mode degrades gracefully — the track drops, siblings continue — but substituting the dry signal for a processed one ships a render that sounds plausible and is not what the author set up. Since the per-element work races under Promise.all, an internal AbortController chained off the caller's signal aborts in-flight siblings before workDir is removed. * feat(core): voiceover carve analysis Finds the bands a voice occupies so a music bed can be dipped there, letting the voice sit in front without ducking the whole track. Carve is a relationship between two tracks rather than an effect on one, so it stays out of the FX chain. What it emits is an ordinary chain of peaking filters, so a carve composes with whatever else is on the track and needs no separate rendering path. Selection is weighted toward intelligibility rather than raw voice energy. Ranking purely by power lands on the fundamental almost every time, because that is where a voice is loudest — but the masking that actually hurts a voiceover happens higher up, and dipping 160 Hz mostly just thins the bed. The bias is a control, not a constant: at 0 it follows raw energy, at 1 it weights toward 1-3 kHz. Ranking happens in dB, which matters more than it looks. Speech spreads 20-30 dB across these bands — it falls off roughly 6 dB per octave above the fundamental — so a weighting has to be on that scale to move anything at all. A multiplicative weight of `1 - bias + bias * shaped` is bounded below by `1 - bias`, capping its influence at 10*log10(1/(1 - bias)): 5.2 dB at the 0.7 default, 3 dB at 0.5. That is no influence against a real voice — every bias short of ~0.95 would rank exactly like bias 0 and carve the fundamental, the outcome the bias exists to prevent, while looking decisive against a fixture whose bands sit 2 dB apart. So the bias is a dB penalty, zero at 2 kHz and worth up to 30 dB at full strength, and relative cut depths come from a dB difference rather than a ratio of weighted linear powers. The bias reweights ranking without overriding the spectrum — a band the voice has no energy in is not worth carving, and scores -Infinity rather than competing — so a strongly low-pitched voice can still select low at full bias. What the tests hold is that biasing never selects lower than the unbiased ranking, that the DEFAULT bias reaches the presence region on a voice with a realistic tilt, and that bias 0 still follows raw power exactly. Includes a radix-2 FFT rather than a dependency; one Welch-style averaged spectrum over third-octave bands does not justify pulling in a DSP library. * fix(engine): keep the FX render 16-bit, stereo, and correctly sized Three defects in the offline FX path, none of which any test could see. **Float output silently disabled sample-accurate volume automation.** The writer emitted 32-bit IEEE float; the very next mixer step bakes the volume envelope into the samples and accepts only 16-bit PCM, returning null otherwise. So enabling any effect downgraded that track to the ffmpeg expression path — capped at 32 straight segments, quantising a curved envelope, and on a dense one falling back to base volume. It now writes 16-bit PCM, clamped rather than wrapped so a limiter at 0 dB or a resonant filter cannot turn overshoot into a click. A test asserts the baker accepts the writer's own output and actually fades it. **Everything was folded to mono.** `prepareAudioTrack` goes out of its way to emit stereo — its pan filter exists to dodge ffmpeg's 3 dB mono-to-stereo rematrix — and this folded it, then wrote one channel. So adding a single peaking EQ collapsed a bed's width and cost ~3 dB in the render, while preview stayed stereo. Channels now travel as one plane each, through an OfflineAudioContext of the same width, and come back interleaved. **Small results decoded the wrong length.** `new Float32Array(buf.buffer)` discards byteOffset and byteLength, and Node pools small allocations: a 400-byte payload sits at offset 8 inside an 8 KiB pool, so a clip under ~1024 samples decoded as 2048 samples of unrelated memory — and the empty-result guard could not see it. The reader has the mirror-image fix: a float data chunk on an odd boundary (ffmpeg's pcm_f32le writes fmt(18) + fact, landing `data` at 58) now copies instead of throwing RangeError on an unaligned view. The tail limitation is now stated rather than mis-stated: the context is exactly as long as the input, so a reverb or delay still ringing is cut there. The old comment claimed the opposite. How far a tail may run past a clip's end changes the clip's length in the mix, so it is a product decision, not one to make here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(producer): report an FX render failure as an audio error `processCompositionAudio` reports per-track failures in its result, but an FX failure it cannot degrade past — a browser that will not launch, a chain that will not build — rejects instead. `runAudioStage` had no try, so that rejection escaped to the orchestrator as an unclassified pipeline exception, losing the stage/owner/retryable classification this stage exists to attach, and skipping its abort check on the way out. It now lands in `audioError` alongside every other cause, while an abort still keeps its own shape rather than being reported as an audio problem. Not done here: committing the generated `audio-fx-runtime-inline.ts` so a fresh clone typechecks packages/engine without building first. The bundle is built from the stub, and the stub changes three times across this stack — so the artifact differs per branch and would conflict on every restack. Its model, position-edits-render-inline.ts, is committed only because it is stable. Building before testing is this monorepo's existing contract (studio's tests need core's dist too), so the gap is not specific to audio FX and is better closed by a build ordering gate than by committing a per-branch artifact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(engine): skip the browser FX render cases when there is no browser CI's `Test` job was red on this PR with four failures, all the same cause: Failed to launch the browser process: spawn /home/runner/.cache/hyperframes/chrome/chrome-headless-shell The job installs ffmpeg and no browser, deliberately — every other suite that needs an external binary already guards on it (`describe.skipIf(!HAS_FFMPEG)`). These cases were the only ones assuming a Chrome, so they failed on an absent dependency rather than on anything about the code. Guards on `resolveHeadlessShellPath()` — the same resolver `acquireBrowser` launches through, so the check cannot drift from the thing it guards the way a hard-coded cache path would. A configured path that does not exist throws; that is caught and read as "cannot run here". Checked both directions rather than just the green one: with a browser all 11 cases run and pass, and with `HYPERFRAMES_BROWSER_PATH` pointed at a missing binary exactly 3 skip and the other 8 still run. A guard that silently skipped everything would have looked identical in CI. They keep their value where it exists — every developer machine, and any job that has run `hyperframes browser ensure`. Not touched: the CodeQL failure on this PR is a run from 2026-08-07, five days and several force-pushes stale. None of the 17 open repo alerts are in files this PR changes; it re-runs on this push. * chore(engine): suppress the temp-file alert with the reason it is safe CodeQL flags `writeWav`'s `writeFileSync` as js/insecure-temporary-file (high) — the one new alert on #3021, and the reason its CodeQL check is red. It is a false positive, and the comment says why rather than just silencing it: `path` is always inside a directory made by `mkdtempSync`, never a name assembled directly under `tmpdir()`. Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * test(engine): probe ffmpeg and Chrome instead of assuming them Two failures on #3021's Test job, both about the environment rather than the code under test. **Bare `ffmpeg` is not on PATH in CI.** The 16-bit fixture shelled out to `execFileSync("ffmpeg", ...)` and died with ENOENT. The job does provide ffmpeg, through `prepare-ffmpeg-bin`, which is what `getFfmpegBinary()` resolves — every other ffmpeg-dependent suite in this package already goes through it. Now this one does too, and the case is `skipIf(!HAS_FFMPEG)` so a contributor without ffmpeg skips rather than fails. **The browser guard trusted the wrong thing.** It asked `resolveHeadlessShellPath()` and treated a returned path as "a browser is here". CI's cache holds a chrome-headless-shell that resolves and then fails to spawn — a partial download is indistinguishable from a working one by `existsSync`, which is all that resolver checks. So the three browser cases ran anyway and failed on the launch. It now runs `--version` and requires exit 0, which is the same probe the ffmpeg suites use: ask the binary, do not infer from the filesystem. Checked both directions rather than just the green one. With a working browser all 11 cases run and pass; with `HYPERFRAMES_BROWSER_PATH` pointed at a binary that exits non-zero — CI's exact situation — exactly 3 skip and the other 8 still run. A guard that quietly skipped everything would have looked identical on the CI summary. * feat(core): register the audio-fx-rack canary at 0% Lands the rollout switch dark, per the registry's own procedure: "Start at percentage: 0 and merge that — a canary at 0 is dead code you can land safely and ramp without a code review." Declared at the bottom of the stack so every branch above can read it. The gate itself goes in at wa-4-fx-panel, where the rack first appears. Scope is deliberate and stated in the description: it gates the AUTHORING surface only. A composition that already carries `data-fx-chain` still plays and renders it. A canary should stage who can REACH a feature, not make an attribute somebody already wrote silently inert — an agent that writes a chain through the skill would otherwise produce a file whose audio processing vanishes with no error. * feat(studio): audio FX panel generated from the registry Controls for the whole chain: add, remove, reorder, bypass, and every knob each effect declares. Nothing in the panel knows what a compressor is. The registry supplies each parameter's range, step, unit and scale and the panel renders what it finds, so adding an effect or a knob upstream needs no change here, and the panel cannot offer a value the renderer would reject — a typed-in figure is clamped into the declared range on the way through. Frequency and time controls span three or four decades, so those declare a log scale and the slider maps exponentially; a linear slider would spend most of its travel somewhere useless. Reorder is a first-class control because chain order changes the sound: a reverb before a compressor is not the same as after. Carve gets its own block rather than an entry in the add menu, with a picker for the voice track to listen to. It processes this track based on another one, which is how a sidechain control works — it lives on the track that changes, and names the source. * feat(studio): show the Audio FX section on audio tracks Adds `audioFx` to the editing-affordances contract and renders the FX panel in the inspector when an `<audio>` element is selected. The section is audio-only. A `<video>` carries its sound on a separate `<audio>` element, so an FX chain on the video would have nothing to process. Chain and carve settings are written straight back onto the element as serialised attributes, the way colour grading carries its config, so persistence is an ordinary attribute write and needs no new server route. A chain that cannot be parsed renders as empty rather than breaking the panel, and the attribute is left untouched until the user changes something. The collapsed group summarises what is on the track ("2 effects + carve") so the state is visible without expanding it. Wired into PropertyPanelFlat rather than PropertyPanel: STUDIO_FLAT_INSPECTOR_ENABLED defaults to true, so the flat inspector is what actually renders. * refactor(studio): lift audioFxSummary out of PropertyPanelFlat `PropertyPanelFlat.tsx` is 612 lines here against the repo's 600-line cap, so the required File size check is red — the sole reason this PR is blocked. The review says as much: "mechanical fix (~5 min), not a design problem. Code itself is LGTM." Moves `audioFxSummary` to `audioFxSummary.ts`, the same file a later branch creates for it. Deliberately the smallest cut that clears the cap rather than the whole `AudioFxGroup` extraction: every later commit in the stack edits AudioFxGroup, so moving it here would collide with each of them, while almost nothing touches this function. 595 lines. * feat(studio): put the audio FX rack behind its canary Gates the rack on `isCanaryEnabled("audio-fx-rack")`, which is registered at 0% — so the whole 47-PR stack can land without showing anyone a feature that has not been measured yet. The gate sits on the AUTHORING surface and nowhere else. The runtime and the render still honour a `data-fx-chain` already on an element, so a composition written through the skill or by `carve.mjs` keeps its processing rather than going silently dry for anyone outside the cohort. A canary should stage who can REACH a feature, not make an attribute somebody already wrote stop working with no error. Gated at the panel rather than in `resolveEditingSections`: the affordance resolver is a pure function in core describing what an element CAN support, and rollout state is not a property of an `<audio>` tag. Pinned the 0% with a test, and checked it fails at 25 — a ramp should have to break something that says "this ships dark" out loud. One gap, stated rather than papered over: the gate itself has no unit test. I wrote one and deleted it, because `PropertyPanel.test.tsx`'s harness never renders the Audio FX group for its audio fixture even with the gate removed — so the test passed for the wrong reason in the off case and could not pass at all in the on case. A test that cannot fail for the right reason is worse than none. Verifying the gate needs the panel harness to mount that section first, which is its own change. * fix(studio): drop the FX panel's dead __testables export Fallow audit flagged it — no test imports the module. * fix(core,studio): clear the remaining Fallow audit findings on the FX panel - Split FxSection's per-node row into FxNodeRow + FxNodeControls so the CRAP score (31.6, threshold 30) splits across two smaller units instead of moving wholesale with one extraction. - Dedupe the repeated "open the add menu, read its items" block in propertyPanelFxSection.test.tsx into openAddMenuItems(). - Merge build-audio-fx-runtime.ts and build-position-edits-render.ts into one build-inline-artifact.ts, config-selected by CLI arg — the two scripts were a byte-for-byte clone save for names. - Exempt canary.test.ts's rawFnv (a deliberate independent reimplementation used to cross-check canaryBucket, per its own docstring) and the property-panel test files' shared renderInto/mount scaffolding (pre-existing across 9 files, 2 outside this stack) in .fallowrc.jsonc, consistent with this file's existing exemptions for the same class of intentional/pre-existing duplication. * fix(ci): allowlist the build-script consolidation in the no-main-deletions guard build-audio-fx-runtime.ts and build-position-edits-render.ts were merged into build-inline-artifact.ts to kill a fallow duplication finding; the deletion guard flagged that as an accidental loss since main still has both originals. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Both callers are covered — the browser host page writes into `mkdtempSync(join(tmpdir(), "hf-fx-host-"))`, and the render output goes to the producer work dir, itself `mkdtempSync(join(tempRoot, "producer-project-"))`. mkdtemp picks the random suffix and creates the directory 0700 in one syscall, so the predictable filename inside it cannot be pre-created or symlinked by another user, which is the attack the rule is about. The analyzer sees the dataflow reach `tmpdir()` and not the mkdtemp in between. Suppressed inline rather than dismissed in the UI, so the justification lives next to the code and the rule stays live for anything added later in this file. Matches the repo's existing convention — `planV2.ts:222` carries an `lgtm[js/insecure-temporary-file]` for a different reason on the same rule. Correcting myself: I first reported this alert as not real, having intersected the PR's files against the default-branch alert list, which does not contain PR-ref alerts. Querying ?ref=refs/pull/3021/merge returns it straight away. * test(engine): probe ffmpeg and Chrome instead of assuming them Two failures on #3021's Test job, both about the environment rather than the code under test. **Bare `ffmpeg` is not on PATH in CI.** The 16-bit fixture shelled out to `execFileSync("ffmpeg", ...)` and died with ENOENT. The job does provide ffmpeg, through `prepare-ffmpeg-bin`, which is what `getFfmpegBinary()` resolves — every other ffmpeg-dependent suite in this package already goes through it. Now this one does too, and the case is `skipIf(!HAS_FFMPEG)` so a contributor without ffmpeg skips rather than fails. **The browser guard trusted the wrong thing.** It asked `resolveHeadlessShellPath()` and treated a returned path as "a browser is here". CI's cache holds a chrome-headless-shell that resolves and then fails to spawn — a partial download is indistinguishable from a working one by `existsSync`, which is all that resolver checks. So the three browser cases ran anyway and failed on the launch. It now runs `--version` and requires exit 0, which is the same probe the ffmpeg suites use: ask the binary, do not infer from the filesystem. Checked both directions rather than just the green one. With a working browser all 11 cases run and pass; with `HYPERFRAMES_BROWSER_PATH` pointed at a binary that exits non-zero — CI's exact situation — exactly 3 skip and the other 8 still run. A guard that quietly skipped everything would have looked identical on the CI summary. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat(core): Web Audio graphs for the FX registry (#3020)
* feat(core): audio FX registry One declarative description of every effect that can be applied to an audio track: fourteen across filters, dynamics, non-linear and time, each exposing its full parameter surface rather than a curated subset. Parameters carry the range, step, unit and scale a control needs, so a panel can generate its UI from this rather than hard-coding a form per effect, and a value that survives `normalizeAudioFxParams` is always safe to realise. Everything is declared in the units a person thinks in — dB, ms, Hz. Parsing rejects an unknown effect id rather than skipping the node. A chain that quietly loses an effect renders something other than what was authored, which is worse than refusing to load it. Data only: no audio is produced here. The graph that realises each effect is referenced by the `web` id and lands in the next change, which keeps this module free of browser globals so the engine and the linter can import it. * fix(core): stop declaring knobs that move nothing Three parameters were declared with ranges, defaults and hints, and read by no builder — dials an author could turn with no audible result. - `chorus.decay` and `bitcrush.aa`: removed. FFmpeg's chorus feeds a decay back into its delay line and a bitcrusher's anti-alias needs a real filter; adding either is new DSP, not a fix, so the honest move is to stop advertising them. - `lowshelf.q` / `highshelf.q`: removed. The Web Audio spec leaves Q unused for shelving filters, so the control moved nothing — and because the shared Q helper marks it automatable, an author could draw an envelope on it and hear nothing at all. `phaser.decay` and `gate.knee` stay: the first drives the sweep depth, and the second is now read by the gate's processor. A test asserts each of these directly, since the existing exposure invariant only checks that a flagged parameter reaches an AudioParam — a parameter the node then ignores passes it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(core): Web Audio graphs for the FX registry One graph builder per `web` id, turning the registry's declarations into running audio. Every node exposes `update`, so turning a dial re-parameterises the live graph rather than rebuilding it: an AudioParam change lands on the next 128-sample quantum, about 2.7 ms at 48 kHz. `buildFxChain` reports whether an update could be applied in place — adding or bypassing an effect, or switching a filter between one and two poles (which changes the node type from BiquadFilterNode to IIRFilterNode), changes the graph's shape and returns false so the caller rebuilds. Four effects have no native node and run as AudioWorklet processors: compressor, limiter, gate and bitcrush. The module is registered from a data: URL rather than a blob:, because a blob inherits the page origin and is opaque on a file:// page, where it fails with an unhelpful AbortError. Reverb has no single node either. `synthesizeReverbImpulse` generates a tail from the room parameters, seeded so the same room sounds the same on every machine, and the ConvolverNode uses it. Tests cover the wiring — which nodes get built, how they connect, parameter application and clamping, in-place update versus rebuild, disposal — against a fake AudioContext, since happy-dom has no Web Audio. * fix(core): reverb level, phaser wiring, per-channel dynamics, one-pole rebuild Four defects in the graph builders, all found by review rather than by ear. **Reverb was unusable at its own defaults.** A ConvolverNode applies the impulse's gain whole — the graph sets `normalize = false` so a room is deterministic rather than browser-defined — but the impulse was raw decaying noise. Measured L2 at the registry default (size 0.7 / damping 0.5): 46.4, or +33.3 dB, putting the wet path ~24 dB over dry at the default `wet: 0.35`. It is now normalised to unit energy, so the wet knob means what it says. Preview and render both convolve this buffer, so they stayed identical throughout — equally deafening before, equally correct now. **Phaser in_gain/out_gain trim the signal entering and leaving the effect**, not a wet/dry pair. Wired to the wet and dry legs, "Input" muted the dry path and the two defaults summed to 1.14, so inserting a phaser raised the track level. They are now input and output trims with the legs summed at unity. Its declared waveform is also honoured: `lfo.type` was never assigned, so the default "Triangular" was silently a sine. **The dynamics worklets held one envelope across a channel-major loop.** The followers advance per sample, so on stereo a 20 ms attack behaved as 10 ms, and the right channel's gain came from an envelope that had already traversed the left — the two ducked differently from the same input and the image pumped. State is now per channel, as is the gate's smoothed gain and bitcrush's sample-hold counter, which previously advanced only on the last channel and left every earlier one frozen for a whole quantum. The gate also honours the knee it declares instead of chattering on material sitting at the threshold. **A one-pole filter's cutoff was swallowed in preview.** Its coefficients are fixed at construction, so `update` cannot push a new frequency — but the shape signature carried only type and pole count, so a cutoff change looked like a values-only edit and went into a no-op updater. Preview kept filtering at the old frequency while the render used the new one: a preview/render divergence in exactly the two effects that do not use a BiquadFilterNode.

feat(sdk): expose a paint query for transparent-composition hit-testing (#3070)
* feat(sdk): expose a paint query for transparent-composition hit-testing A host layering a transparent composition over other content has to know whether a point carries ink before it decides to swallow a click. The adapter only answered "what element is here", so AI Studio wrote its own answer and could not reach the per-pixel alpha the adapter already samples for <img>. Add PreviewAdapter.paintsAt, plus the pieces it is built from on a new ./adapters/iframe subpath so a host with different hit-test policy can compose its own walk. The walk is geometric rather than elementsFromPoint-based: that stack omits pointer-events:none nodes, and a decorative overlay carrying it still paints, so a z-stack query would report no ink over visible artwork — the direction that makes a composition vanish from under the cursor. fullBleedFraction is an option rather than a constant because "a layer covering the whole frame is background, not artwork" is host policy, not a fact about the composition. * fix(sdk): scope the full-bleed frame to the root under the point compositionFrameArea took the smallest [data-composition-id] in the whole document, so an unrelated sub-composition sized the reference frame for points nowhere near it: a 300x300 badge in a corner made every mid-size painter in a 1920x1080 outer frame read as full-bleed, and the composition went click-through under artwork the user can plainly see. That is the direction the fail-safe exists to avoid, and the docs already described the intended behaviour — the innermost root CONTAINING the point. Also read the alpha channel instead of matching known transparent spellings. Only the `transparent` keyword computes to rgba(0, 0, 0, 0); a faded-out white stays rgba(255, 255, 255, 0), which the set counted as painted. That erred toward absorbing clicks rather than losing them, so it was a false positive rather than a hazard, but it is wrong. Both are pinned by tests that fail when the fix is reverted. * fix(sdk): stop the paint query answering "no ink" over visible artwork Four cases where the walk landed on the wrong side of its own fail-safe. The full-bleed veto tested the winner's border-box area even when the alpha sampler had just read an opaque pixel there, so a full-frame transparent PNG or SVG overlay — the case this feature exists for — reported background over visibly opaque artwork, with no fullBleedFraction that worked. Ink now carries how it was established, and a measured pixel is never vetoed. An image whose pixels could NOT be read stays inferred, so a tainted CDN overlay still yields to the veto rather than absorbing every click. Composition roots were excluded from candidacy outright, so a root carrying a background answered false even at fraction 0, where the docs promise every painting box counts. Roots are candidates now; the veto discounts them without a special case, since a root's box is the frame. An <img> with a clear pixel early-returned past its own background, padding plate and border, which any other element would have counted. A same-origin iframe mid-navigation exposes a readable but empty document, so the !doc guard never fired and a loading composition answered a confident "no ink" — the exact failure the null convention exists to prevent. Also: the sort comparator's epsilon tie was intransitive, leaving the smallest-first guarantee (and the lazy single-sample property that rides on it) engine-dependent; the guide's pass-through recipe called a function that does not exist and hand-waved the coordinate mapping that makes it correct; and the reference now states the under-counts alongside the over-counts, the walk's blindness to runtime-mounted content, and compositionPaintsAt's preconditions. Each fix is pinned by a test that fails when the fix is reverted. * refactor(sdk)!: invert the paint query to isProvablyEmptyAt paintsAt handed callers three falsy bottom values with opposite safe readings: false meant "no ink, pass the click through", null meant "not knowable, treat as painted", and undefined from an adapter without the method also meant painted. The idiomatic `if (!preview.paintsAt?.(x, y)) passThrough()` therefore did the dangerous thing for two of the three, and the convention needed defending in the interface docstring, the reference and the guide — plus a dedicated comment and a pinning test on the headless adapter to stop null regressing to false. Inverting the polarity collapses the tri-state to a plain boolean and makes the safe reading structural: true only when the composition was readable and nothing painted there, so ink, an unreadable or still-loading document, and a missing implementation all land on "keep the composition clickable". The prose stays as rationale, but nothing depends on a reader remembering it. PaintsAtOptions becomes PaintQueryOptions, since it now describes the walk that both the adapter method and the exported compositionPaintsAt share rather than one method's arguments. compositionPaintsAt keeps its ink-positive name: it answers the other question, and its docstring points callers who need the fail-safe contract at the adapter. Nothing is released yet, so no consumer is on the old name. |

fix(studio): keep dense keyframes readable (#2925)
* perf(studio): define timeline viewport budgets and fixtures * test(studio): gate timeline viewport performance in Chromium * refactor(studio): isolate clip drag lifecycle * refactor(studio): extract timeline render contracts * perf(studio): centralize timeline viewport geometry * perf(studio): follow playhead across virtualized rows * perf(studio): add timeline clip-window index primitive * perf(studio): virtualize timeline clip windows * perf(studio): stop timeline scroll work when row virtualization is off The row virtualization stack made the timeline publish a viewport snapshot on every scroll frame and swap `renderClipContent` across every mounted clip at gesture start and settle. Both are windowing concessions, and neither was gated on the flag, so the build users actually run paid for them while mounting all 1,000 clips anyway. Measured on a 3,000-clip project: median scroll step 16.6ms to 76.9ms, p95 17.9ms to 189.4ms, 40 long tasks to 247. Gate both on the row virtualization flag. The scroll path now stops at the door when the flag is off, so `isScrolling` stays false and resize-driven and programmatic syncs still publish through the immediate path. The flag moves into its own module: the scroll-viewport hook needs to read it, and the virtualization hook already imports the viewport snapshot type back, which would have closed an import cycle. Also release the perf fixture lease from the fixture rather than from the test-hook effect. Loading a fixture writes player state, which changed that effect's dependency identities and tore it down on the next frame, so the lease was revoked moments after it was taken and live iframe discovery overwrote the fixture before the gate could measure it. The e2e gate gains a flag-off arm (`test:timeline-default`, 1,000 elements) next to the existing flag-on one. It refuses the 50,000-element combination, verifies from the mounted DOM that the server under test matches the requested flag, and skips the DOM-size budgets for the unvirtualized build rather than relaxing them, so a skipped budget never reads as a passed one. Verified against a live Studio dev server on the fixture project: flag off, before: interactionP95 303.1ms, longest task 194ms, 0/5 runs pass flag off, after: interactionP95 33.6ms, longest task 0ms, 5/5 runs pass flag on, after: interactionP95 33.2ms, 4/5 runs pass, exit 0 The flag-on arm's fourth run reproducibly reports a 55-58ms long task against a 50ms budget. That is the residual tail of the window swap itself, tracked separately and not addressed here. * ci(studio): run the timeline viewport gate on studio changes The gate has existed since the row virtualization stack landed but nothing under `.github/` referenced it, so it only ever ran when someone ran it by hand. That is how the flag-off scroll regression reached eight merged-ready PRs without anything noticing. Adds a `studio-timeline-viewport` job that boots two Studio dev servers, one per flag state, and runs both arms of the gate against them. Two servers are needed because row virtualization is read from `import.meta.env` at module load, so one process cannot serve both builds. Scoped to a new `studio` paths filter rather than the broad `code` one: the gate only says anything about `packages/studio`, `packages/core` and `packages/studio-server`. Adds a `ci` tier. It applies the constrained budgets without any emulation, because a hosted runner is already slower and noisier than the machine the strict numbers were recorded on, while the existing `low-resource` tier would throttle it a further 4x and measure the throttle rather than the build. The fixture composition is tracked under `tests/e2e/fixtures` but Studio resolves projects from the gitignored `data/projects`, so the job copies it into place instead of a project directory being committed. Both arms run in about 7 seconds each locally, so the job cost is almost entirely dependency install and the workspace build it shares with `studio-load-smoke`. * fix(ci): preserve both timeline gate evidence arms * ci(studio): report timeline gate arm statuses * ci(studio): require timeline gate evidence artifacts * fix(studio): keep dense keyframes readable * fix(ci): resolve timeline stack audit findings |

feat(lint): add off_pivot_rotation hub-referenced layout check (#2744)
## What it catches A gauge needle / clock hand / dial pointer / radar sweep that rotates about the **wrong pivot** — the recovered center-of-rotation sits far from the dial hub (e.g. `transform-origin` at the needle base or SVG element edge instead of the dial center). Visually the needle "wobbles" or orbits off-axis instead of sweeping cleanly about the hub. This is a genuine gap in the current checks: `rotation_pivot_drift` (#2741) provably **cannot** catch it — a correct sweeping needle's bbox-center orbits identically to a broken one, so only a **dial-hub reference** distinguishes them. This is the separate hub-referenced check that analysis called for. ## How it works - Sampler maps 2 material endpoints per frame via `getScreenCTM` (honors the actual rendered transform, independent of `svgOrigin`). - Resolves the dial hub = shared center of the modal set of static concentric circles, or the arc-center of the largest static near-circular path (Kasa circle fit). - Fits a circle to the endpoint trajectory to recover the true center-of-rotation; flags drift `> 0.35 * pointer_length`. One warning per hub. - Never fires without a resolvable hub. Walks the rotation reference to the composition root (not the `<svg>`) so a pointer rotated by a `div` ancestor is measured correctly. - Multi-body guard: `>= 2` bodies at distinct angular positions on one hub = orbit/atom system, not a dial → suppressed. ## Corpus evidence (autonomous geometry-fuzz run, 81 fuzzed diagrams) - **7 / 7 true positives, 0 false positives across all 81 samples.** - Assigned TPs: fuzz005, fuzz017, fuzz032. Bonus TPs: fuzz044, fuzz056, fuzz068, fuzz080. - **The Gemini-3.6 video-judge itself MISSED all 4 bonus TPs** (`vlm_has_defects: false`) — the deterministic hub-reference check beats the VLM on this defect class. - FPs driven to 0 by the two principled guards above: fuzz016 (planet arc rotated by a `div` ancestor) cleared by root-walk; fuzz055 (atom) cleared by the multi-body guard. - fuzz080 reads as a false positive to the connector check but is a true positive here — confirms the architectural boundary between the two checks is drawn correctly. ## Validation - Autonomous Gemini-3.6 **video**-judge fuzz run to surface candidate defects, then a **deterministic FP sweep** across all 81 rendered compositions (not VLM-gated — code inspection is the arbiter, since the VLM both over- and under-calls this class). - 9 unit tests (`checkPipeline.offPivotRotation.test.ts`) + full check suite pass; `bun run build` green. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(fallow): suppress line-shifted pre-existing findings + simplify CSS.escape polyfill
Fallow audit failed on the parent PR (#2563) with 8 findings, all of them tracing back to line-shift fingerprint invalidation on pre-existing complexity/ duplication, plus one new-but-easily-simplified CRAP finding on the CSS.escape polyfill in picker.test.ts. Actions: - picker.ts: 5 pre-existing inherited-complexity findings (isEffectivelyHidden, isPickableElement, buildElementLabel, getPickCandidatesFromPoint, pickManyAtPoint). All in the file at the parent SHA. The one-line buildElementSelector edit (+ 3-line comment) shifted every function below it, re-triggering the fingerprint. Added to health.ignore with rationale. - screenshotClip.ts + vite.browser.ts: 19-line clip-computation clone that pre-dates this PR — the try/catch guard around querySelectorAll shifted screenshotClip.ts's clone-start line, re-flagging the inherited duplication. Added both files to duplicates.ignore with rationale (splitting the clone would require crossing puppeteer's page.evaluate serialization boundary). - picker.test.ts CSS.escape polyfill: simplified from a 15-line char-by-char loop (CRAP 56.3, cyclo 14) to a compact regex + leading-digit special case (~4 cyclo). Still handles the digit-leading case this PR's regression test needs (`#0` -> `#\30 `); the round-trip through querySelector still asserts the element is picked back. All 16 picker tests + 3 screenshotClip tests still pass locally. Change by Via |
