fix(producer): seek once per step when discovering video visibility (#3233)
Seek the GSAP timeline once per timestep and sample every auto-start video, instead of re-walking per media element. Keeps probe cost proportional to duration, not video count. |

fix(producer): give inlined media a document-unique render id (#3342)
* fix(producer): give inlined media a document-unique render id
Element ids are unique per composition file, but the render document is
the inlined union of every file. The producer merged the per-file media
lists and deduplicated by id, so clips that shared an id collapsed into a
single entry, and every id-keyed stage (extract, inject, visibility,
bounds) resolved to whichever element came first in the document. The
surviving clip's frames landed on the wrong element and the visible scene
rendered without footage.
Two shapes hit this, and neither is author error:
- Two scenes that each declare `<video id="clip">`. Legal per file, and
unavoidable when a scene is duplicated into a copy with inner ids
kept, or when one file is mounted twice.
- Two scenes that each declare a bare `<video>`. The timing compiler
numbers auto-ids per file, so both arrive as `hf-video-0` with no
authored id involved at all.
Stamp a document-unique `data-hf-render-id` while inlining, and read the
media list off the inlined document instead of merging per-file lists.
The render id equals the element id whenever that id is already unique,
so documents without a collision keep identical pipeline keys.
Author `id` attributes are left alone: 158 of the 161 registry blocks
reference their own ids from `#id` CSS or getElementById, so renaming
would trade broken footage for broken styling. The engine resolves media
elements through the render id instead, falling back to getElementById
for documents the producer never compiled.
Collecting from the inlined document also retires the per-file media
extraction in parseSubCompositions along with its offset bookkeeping;
host offsets are recovered from the composition hosts the clip sits in.
* fix(core): resolve render-frame siblings by render id in the runtime
The injector creates each `__render_frame_<id>__` sibling from the media
element's render id, but four runtime readers still built that id from the
plain `el.id`. On a document where two compositions share a media id, all
of them resolved the first collider's frame.
colorGrading is the one that changes pixels: findRenderFrameImage returns
the image the grading pass samples, with no class check to catch the
mismatch, so the second video was graded from the first one's frame.
media, mediaProxy and video-texture-compat use it as a render-mode or
substitute-source signal, where both colliders happen to agree during
render, but none of them should rest on that.
Add renderFrameSibling as the single owner of "which frame belongs to
this element" and route all four through it. It reads the stamped render
id and falls back to the author id, so a collision-free document resolves
exactly as before and an uncompiled one (preview, snapshot, check) is
unchanged.
The engine's in-page bridge keeps its own copy of the rule because code
serialized into page.evaluate cannot import; it now names core as the
definition, and a test pins the sibling-id format both sides build so
they cannot drift apart silently.
* refactor(engine): build render-frame sibling ids from core's definition
The drift guard named both sides but pinned one. renderFrameSibling.test
asserts core's format, while the engine rebuilt the same id from a literal
template at six independent sites. Changing the format on either side left
the test green and every runtime reader silently unable to find its frame —
this PR's own failure mode, one level up.
Export the affixes and renderFrameIdForRenderId from core, and take the id
from there at all six. Four sites resolve it on the Node side, where the
engine can import; the two that iterate the DOM in-page receive the affixes
as evaluate arguments, which avoids depending on bridge install order.
Also switch two `__hfMediaId?.(el) ?? el.id` reads to `||`. The bridge
returns "" for an element with neither id, so `??` kept the empty string
and built `__render_frame___`, which no reader looks for. Inert today
because the compiler assigns positional ids to id-less timed media, but it
made the two sides disagree in the one case they could.

fix(audio): raise the authoring gain ceiling and carry it through the probes (#3333)
* fix(audio): raise the authoring gain ceiling and carry it through the probes Builds on #3328, which made the preview graph apply author gain and user volume exactly once each. That ownership is now correct but everything is still clamped to 1.0, so a clip authored above unity cannot be heard or rendered. `HTMLMediaElement.volume` is spec-clamped to [0,1], so both timeline probes lost a clip's authored gain the moment it also carried a fade: the probe seeded the element at the clamped value and every sample read back at or below 0 dB, and the mixer prefers probed keyframes over the static volume. Both probes now shadow the accessor for their own duration and forward the clamped value to the native setter, so the authored gain survives while nothing outside the probe ever sees an illegal volume. Measured on one 6 s composition, first 4 s: unity -32.8 LUFS, boosted-with-fade -32.8 before and -27.0 after — +5.8 dB, exactly the gain the clip was authored at. One ceiling, defined once in `audioGain.ts` and reachable from both sides: the render mixer imports it, and the page-serialized probe takes it as a parameter rather than re-literalling it. User volume stays spec-clamped — it is a fader, not a gain. Also holds the percent volume slider above unity in both property panels. That control tops out at 100%, so one touch would cap a boosted clip and drop up to 12 dB that now genuinely renders; the dB fader that can represent these levels replaces it in the next PR. * fix(audio): carry a static above-unity gain onto the preview gain node Review follow-up. `setElementVolume` receives the clip's author gain and clamped it to [0,1], so a static `data-volume` above unity was capped on the WebAudio preview path while the render honoured it — the exact preview/render divergence this ceiling exists to close. Automation lanes hid it: they schedule ramps onto the param directly and never pass through here. The master volume beside it stays spec-clamped, because a user fader is not a gain. Verified by mutation: restoring the [0,1] clamp reds the new case. Also scope the leveller's rationale to this rung — `VOLUME_RANGE` still stops at unity until the dB fader lands, so "both now span the same range" was premature — and say why the GSAP-tracking fallback is unity-capped: it reads back through `el.volume`, which the spec pins to [0,1], so it cannot observe an above-unity value however wide the clamp gets. * fix(audio): restore the live test files this branch overwrote, and uncap preview Review blocker: three files were wholesale copies from the abandoned #3304 branch laid over a two-day-newer base, so they silently reverted work that had landed in between. CI could not see it — deleted tests do not fail. - `audioMixer.test.ts` was byte-identical to #3304's head: 1186 lines against a base of 1353. Gone with it were the `data-playback-start` fallthrough cases from #3322 — merged 54 minutes before this branch's own merge base — and all retiming coverage (`playbackRate` 7 to 0, `atempo` 5 to 0), the strict literal-timing table, and the zero-window cases. - `mediaVolumeEnvelope.test.ts` dropped the trailing-garbage duration case and the plateau-retention case. - `packages/core/package.json` rolled the package version back 0.8.3 to 0.7.109. All three are restored from `main` with only this PR's additions re-applied on top, and the subpath export is regenerated by the repo's own script rather than hand-edited. Also closes the preview/render split the same review raised. Two clamps had to go, not one: `setElementVolume` capped the author gain at the transport, and the first-tick branch in `syncRuntimeMedia` trusted `el.volume` — which is spec-bound to [0,1] and so cannot represent a boost, opening a boosted clip at 0 dB for one tick before the steady-state branch took over. Both pinned by tests, both verified by mutation. |

fix(producer): clamp embedded video/audio windows to the scene (#3332)
Browser probe end reflects full source duration, not the scene slot. Never extend a compile-time end — only fill missing or shrink — so long recordings sliced across short scenes don't inflate extraction windows and time out black on Cloud Run (ARC-13403). |

fix: create temp dirs with mkdtemp, not a name built from Date.now() (#3241)
* fix: create temp dirs with mkdtemp, not a name built from Date.now() Closes nine open `js/insecure-temporary-file` alerts — the technically correct ones. An audit of all 29 open alerts for that rule split them three ways: - 19 false positives: the write lands inside a directory the caller already made with `mkdtempSync`, and CodeQL's dataflow reaches `tmpdir()` without seeing the mkdtemp in between. - 1 mitigated: `fontCompression.ts` writes with `flag: "wx"` and only takes the tmpdir branch inside Lambda, where /tmp is single-tenant. - 9 real, and these are them. A name built from `Date.now()` under the shared temp dir, followed by `mkdirSync`, is guessable to the millisecond AND leaves a window between choosing the name and creating it, so on a shared machine another user can pre-create or symlink the path first. `mkdtempSync` closes both halves: it picks the random suffix and creates the directory 0700 in one syscall. Same shape, one line shorter, and the alerts go away rather than being dismissed. Six sites in `normalize.test.ts` (its `mkdirSync` import goes with them), one in `generate-catalog-previews.ts` — that single construction accounted for three alerts, since the other two were writes into the directory it made. No shared helper. `mkdtempSync` is already the stdlib primitive for exactly this, and the two callers live in different packages, so a wrapper would need a home in core to serve one CLI test and one build script — more indirection than the line it saves. Deliberately not touching the other 20: excluding the rule repo-wide would hide this class of bug from future code, which is the reason these are fixed rather than silenced. * fix: track the wav temp dir for cleanup and finish the mkdtemp sweep The wav helper pushed the file path into `dirs`, so `afterEach` removed `tone.wav` and left the directory it had just made — four per suite run. Push the directory and derive the file path from it. Measured: the old code leaks 4 directories per run, the new code leaks 0. Three sites still built a predictable name and then created it. CodeQL never flagged them — its dataflow reaches the template preview writes through a `readdir` walk and does not connect them back to the `tmpdir()` root — so the alert list was narrower than the pattern, and closing only the alerts would turn the rule green while the shape survived where nothing would re-flag it. `generate-template-previews.ts` is the near-twin of the file this change started from, and the other two are producer dev entry points. All three use the path only through the variable, so the random suffix changes nothing. Catalog previews now call the existing `createCatalogPreviewTempDir` instead of repeating its body. That test was in no runner, so it pinned uniqueness and mode 0700 on a function nothing called; adding it to `test:scripts` alongside a real caller makes it load-bearing. The rationale for the primitive moves to the helper, which is now the only place it lives. * ci: re-run catalog previews when the temp-dir module changes Routing the renderer through `createCatalogPreviewTempDir` made that module part of its runtime path, and the workflow already states the rule for the sibling case: a module the renderer imports has to appear in the trigger, or a change to it alone never re-runs the job that exercises it. Add it to the `paths:` filter and to the renderer canary, so a PR touching only the temp-dir allocation still renders both shape canaries. Verified against this branch's own range: the previous argument list does not report the file, so a helper-only PR was invisible to both checks. |

feat(engine): stamp rendered files with hidden renderer provenance (#3264)
* feat(engine): stamp rendered files with hidden renderer provenance * fix(engine,producer): re-assert provenance at every container writer Review found that a no-audio MOV render still shipped untagged. The concat step is the last container write on that path (mux is skipped without audio, and applyFaststart only copies mov/webm), and the concat demuxer does not carry the chunks' container metadata through. The same hole applies to no-audio WebM, and to the in-process chunked encode in chunkEncoder, not just the distributed assemble path. mp4 was masked throughout because applyFaststart re-runs ffmpeg for that format and re-tagged the output. Tags the four remaining writers: the chunked-encode concat, and assemble's single-chunk remux, concat and cfr re-encode. Also corrects the trust claim. These are unsigned, freely writable keys, so a present tag means the file claims to be HyperFrames output, not that HyperFrames wrote it. Documented as an unauthenticated diagnostic hint rather than an authenticity or attribution boundary. Tests assert on the assembled file through the real assemble() path for both mov and webm; both fail without the concat fix. * test(engine): pin provenance through the in-process chunked concat Review noted the distributed writers are mutation-pinned but the encodeFramesChunkedConcat fix had no real-file regression of its own. Encodes 70 frames at a 30-frame chunk size so the concat step actually runs, then asserts the tags on the resulting no-audio mov. Fails without the concat fix, passes with it. |

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> |

fix(core): make audio automation survive being rescheduled (#3208)
* 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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(studio): cover carve visibility through the real element The panel derives carve's source list from the selected element's document, so a selection with no element has no sources — which the new visibility rule correctly reads as 'nothing to carve against'. The suite mounted exactly that, so it was asserting on a hidden block. Selections now carry a real <audio> with a sibling track, and the two cases the rule exists for are pinned directly. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): keep FX panel writes from clobbering each other Three writes in the audio panel each read the source file, mutate one attribute and write it back. Fired without ordering they read the same content and the last one lands, dropping the others. - Deleting an effect left its automation lanes in the attribute. 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> * feat(studio): internal clipboard for automation ranges * feat(studio): copy and paste automation ranges across lanes Extends the automation-selection keyboard hook with Cmd/Ctrl+C (copy the active range) and Cmd/Ctrl+V (paste onto the selected clip's lane, at the selection's start or the playhead, chaining the selection to the pasted span so a second paste lands right after the first). Paste falls through untouched when no target lane resolves, so clip-level paste keeps working. Also fixes a latent test-isolation bug: setup() never unmounted the previous test's Host, so document keydown listeners leaked across tests and could consume later events before the current test's own listener ran. * 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(studio): retime an automation selection Add retimeRange pure operation that scales interior points proportionally into a new time span, then uses replaceRange to update the lane while preserving the envelope outside the union of old and new ranges. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(studio): repair the automation paste path and finish the key arbitration Paste was the least safe path in this feature: it resolved its target from the player store but committed through a different, asynchronously-lagging channel. Six review findings against this branch, plus the Cmd+C/Cmd+V half of the arbitration wa-15 started for Delete. - Write channel: resolvePasteTarget bails unless the binding's commitTargetKey equals the element it resolved. useAutomationLanes exposes that key, resolved through resolveTimelineIdForSelection — the same resolver applyDomSelection uses — and read in the same render as the commit handlers, so a handler and the key cannot describe different moments. Before this, clicking clip B then immediately pasting serialized B's automation onto A and left B untouched. - Chaining: the paste anchor comes from sel.t1, not sel.t0, so a second Cmd+V lands after the first instead of on top of it. The old comment claimed the new behaviour while the code did the opposite, and no test pressed Cmd+V twice. - Empty copy: copyRange returns false rather than arming a clipboard whose every paste is a destructive flatten, and samples the range's edges so copying a smooth stretch yields a real segment instead of no points. - Playhead: the playhead branch requires the playhead to be inside the clip rather than silently clamping an out-of-clip playhead to the clip's start. - Keys: one chord helper normalizes with toLowerCase() and gates on !shiftKey && !altKey, matching useAppHotkeys. CapsLock no longer kills the shortcut and Ctrl+Alt+V no longer pastes where the app declines. - Arbitration: useAppHotkeys consults automationOwnsKey before its c/v branch, so an active range keeps Cmd+C/Cmd+V from the clip clipboard the same way it keeps Delete. Without it Cmd+V duplicated the clip while the automation paste wrote the same file, and Cmd+C armed both clipboards. It returns without preventDefault — the downstream handler needs the key — and declines when the automation clipboard is empty so clip paste still works. dispatchModifierKey is exported to pin this, like dispatchPlainKey. - Double-action: the hook now returns early on e.defaultPrevented. useAppHotkeys is on window/capture and deliberately lets a keyframe selection outrank a range on Delete; without this that press deleted the keyframes there AND emptied the range here. - Project scoping: the clipboard scopes itself. Every entry point carries the project it speaks for and a mismatch empties the module, the shape keyframeSlice already uses to discard a request from a previous session. Scoping it inside the module rather than clearing it from the session seam is deliberate: the failure is silent and destructive — a range copied in project A pasted into B is remapped through A's captured sourceRange for an FX node B may not have, and the keystroke is consumed so clip paste never runs — so no future caller should be able to forget the guard. The mark isLastPasteSpan reads is scoped transitively, through the same check. - Session reset: createTimelineResetState clears automationSelection. It is as ephemeral as selectedKeyframes, and a range surviving a project switch can match a same-keyed clip in the new project and redirect a paste through sel.elementKey === paste.elementKey to a stale t0. Five of the six paste fixes above shipped without a test that fails without them, which is how the branch reached review with a comment describing chaining that the code did not do. Each now has one: a second Cmd+V landing after the first, a commit-target mismatch declining, an out-of-clip playhead declining, an empty-lane copy leaving an earlier clipboard intact, and Cmd+V with CapsLock on. All five fail against this branch's parent. * test(studio): probe retimeRange's actual guarantee, not sample-continuity past a moved edge The failing test probed t=5.1, which sits inside the reshaped transition segment between the new edge (t=5) and the existing point (t=6). When growing past an existing breakpoint, the transition TO that point legitimately reshapes — the edge moved (t=3→t=5) even though the far point (t=6) did not. The real guarantee: all BREAKPOINTS strictly outside the union keep exact (t, v) values. Corrected test to: 1. Verify sample continuity on unaffected side: t=[0,1,1.9] 2. Verify the breakpoint at t=6 keeps exact value: (t:6, v:0) Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(studio): stretch an automation selection by its edges Add an edge-handle drag to a selection's rect: grabbing within 8px of either edge retimes the selection via the already-landed retimeRange, scaling interior points proportionally and clamping the dragged edge against its partner and the clip's duration. Priority is point-drag > curve-drag > edge-stretch > new-range-select, so a point sitting on an edge still wins the press. Cursor shows col-resize while hovering or dragging a handle. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(studio): retime edge-stretch from a fixed points snapshot moveEdge fed retimeRange the live draft on every pointermove while origin.t0/t1 stayed pinned to the drag's start. retimeRange is a relative transform that scales a lane's own current point positions, so repeated pointermoves compounded the scale factor (interior points drift toward the far edge) and could drop points that retimed past the selection's original bound out of the next move's `inner` set entirely. Snapshot lane.points at arm time (armBackgroundGesture) alongside the existing frozen origin, and always retime from that snapshot in moveEdge instead of the live draft. finishEdgeDrag is unchanged: it already just persists the last (now-correct) preview. Adds a regression test asserting a multi-pointermove edge-drag (both edges) lands on the exact same final points as a single-shot drag to the same target — the case that exposed the bug, since the existing suite only ever tested a single move. * fix(studio): clamp selection-start paste, sharpen clipboard test, cleanup - useAutomationSelectionKeyboard: clamp the selection-start paste branch to [0, element.duration - clip.span], same as the playhead branch already does. An unclamped paste near a clip's end could write points past element.duration and leave the resulting selection's edge ungrabbable off the visible lane. - automationClipboard.test.ts: swap the cross-parameter mapping test's target from fx.r.wet (numerically identical to VOLUME_RANGE) to the log-scaled fx.n1.frequency, so the test actually discriminates real unit-space mapping from a linear guess or a verbatim value copy. - automationLaneSelection.ts: drop the lone `!` non-null assertion in decimateEvenly's budget-of-1 branch for a guarded pattern, matching the loop right below it and the repo's no-`!` convention. - .fallowrc.jsonc: remove the two ignoreExports entries for AUTOMATION_SHAPES and simplifyPoints — both are now genuinely consumed (AutomationSelectionMenu.tsx, TimelineAutomationLane.tsx). - AutomationSelectionMenu.tsx: port TrackGapContextMenu's viewport-edge clamping so a right-click near the bottom/right of the timeline doesn't render the shape/simplify menu partially off-screen. * fix(studio): give edge-stretch the gesture contract the other four follow Seven review findings against this branch, five of which were one defect: edge-stretch was added as a fifth mutually-exclusive gesture on the lane without joining the threshold / live-preview / revert-on-cancel contract the point drag, curve bend, range drag and double-click all obey. Patching them one at a time would have been more code and less coherent, so this makes the stretch structurally parallel to its sibling range drag instead, and extracts it to useAutomationEdgeStretch on the way out — the gestures file had ~60 lines of headroom under the 600-line studio cap, and shaving comments to fit a refactor in is not a plan. - Threshold. A press within the 8px halo of either edge used to persist a no-op commit and push an undo entry that changed nothing (commitDataAttribute has no unchanged-value short-circuit). Worse, it made the pre-existing "click the background to clear the selection" escape unreachable anywhere near an edge. Below 3px of travel — the same threshold the range drag uses — the press now clears the selection and writes nothing at all. - Live preview. moveEdge never fired onRangeSelect and the hook discarded the drag's live position, so the highlight rect and both edge lines stayed pinned at the pre-drag bounds for the whole gesture and snapped into place on release: the user dragged an invisible handle. It now reports bounds on every move, exactly as the marquee drag does and for the same reason. - Revert on cancel. pointercancel means the browser abandoned the gesture; it was routed to the same handler as pointerup, which persisted whatever partial retime it had reached. It now restores the arm-time snapshot through the preview channel — there is nothing persisted to undo — and puts the selection back. A new cancelDrag handler owns that, so a release and an abandonment are no longer the same event. - Lost capture. capturePointer took the capture on e.target, i.e. whichever child the press landed on. A child that unmounts mid-drag takes the capture with it, silently, with no pointercancel — after which edgeDrag stayed non-null and every later button-less pointermove kept retiming and writing. Capture is now taken on the svg, which outlives every gesture on it, and a move reporting no buttons held ends the drag as a cancel. - Hit priority. A breakpoint sitting exactly on the selection's edge used to win the press. Since replaceRange pins an anchor at the union bound and finishEdgeDrag leaves the selection edge at that same time, EVERY range operation — stretch, delete, shape insert — leaves a point exactly on the edge it just created: the second stretch of the same edge resolved to a point-drag, at the one height (on the envelope) where a user naturally grabs it. The feature was not repeatable. An active selection's edge now outranks a point on it; clearing the selection reaches the point again, which is tested. - Clamp order. The dragged edge was bounded against its partner AFTER the 0-floor, so a selection thinner than the minimum width yielded a negative t0, which core's cleanPoint then collapses onto a duplicate t=0 on the serialize round-trip — silent envelope corruption. The floor is now applied last. The minimum width is its own MIN_SELECTION_SEC rather than a borrowed POINT_MERGE_SEC: when two breakpoints are the same breakpoint is a different question from how thin a time selection may get. One finding does not survive: edgeAt's `d0 <= d1` tiebreak was reported as making the t1 edge ungrabbable on a narrow selection, but that comparison IS nearest-wins, and a press right of the midpoint already resolved to t1. The midpoint split here is the same rule written so it is legible rather than inferred, and the test for it is labelled as characterizing behaviour, not fixing it. What was genuinely unreachable inside a narrow halo — starting a fresh range, or clearing the old one without Escape — the threshold above fixes. Also settles what retimeRange does with a breakpoint sitting ON a dragged edge, which was never decided: pointsIn is endpoint-inclusive, so it is interior and travels with the stretch. It has to be, because the commonest stretch of all is grabbing an edge to drag exactly that point outward, and anchoring it would delete it and flatten the span instead. The price is that the retimed point lands on the union's own boundary where a preservation anchor would go, and anchor() stands down within a merge radius — one time cannot hold two values — so the segment leaving the union reshapes. That is the one place replaceRange's outside-never-moves invariant bends, and both halves are now pinned: the exact points and the sampled slope for the on-edge case, and the full two-sided invariant for a selection whose edges are off any breakpoint. The earlier right-side probe at t=5.1 that caught this was deleted during development as inherent; it was reporting the real behaviour. * fix(core): make audio automation survive being rescheduled mid-playback Anything landing inside a running value curve is refused unless the parameter is cancelled first, and two paths were not cancelling: the chain observer wrote each knob straight onto its AudioParam before rescheduling, and a bent segment read as straight because only the curve exponent was checked, never the via point the timeline actually writes. The first threw NotSupportedError into the console and abandoned the rest of the envelope; the second played a dragged bend as a ramp. Measured against Chrome, in a live context and in an offline one suspended mid-curve: any cancel frees the span, and only a missing cancel is refused. clearParamLane takes the strongest form on purpose, because curve-over-curve refusals were reported with a cancel at the new schedule time already in place and have never reproduced; emit keeps a ramp fallback as the backstop for whatever that mechanism turns out to be. Dynamic carve is what exercises all of it, so it lands here too: - a `gain` primitive, so a carve can match levels as well as carve bands - carve settings collapse to one `strength`, with carveProfile deriving the six numbers that always moved together anyway - analyseCarveDynamics / analyseCarveDuck turn the analysis into envelopes, with a slow release so the bed does not snap back the instant a word ends - worklets are awaited inside attach, so adding a compressor to a carved bed no longer kills its envelopes and freezes every later edit - per-track failure detail in the render's audio stage, which was being discarded Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * feat(studio): select automation points with a box, and stop them crossing Replaces the time-range selection with a rectangle. A lane selection is a set of breakpoints, not a span, so it now has value bounds as well as time bounds and a point is caught only if it falls inside both — which is what lets you take the peaks of an envelope and leave the dips between them. Delete, the group drag and the rings drawn on caught points all read the one rule, so what looks selected is exactly what those act on. Copy, paste, shape insert and simplify still work on the box's time span, because they act on the envelope over a stretch of time. Dragging is bounded by its neighbours in both the single and group cases. A point cannot cross another, and cannot land exactly on one either: the lane collapses points that share a `t`, keeping the later one, so arriving on top of a neighbour deleted it. It stops a millisecond short, which is under a pixel at any zoom the lane offers and keeps both points. Only stationary neighbours constrain a group, per member rather than per end, since a box can select a non-contiguous set. Edge-stretch is removed rather than fixed. Dragging a selection's edges to retime the points inside it was the feature this branch opened for, and it is not wanted: the hook, retimeRange, the edge handles, the col-resize cursor and the pointercancel revert path all go, along with the ~360 lines of tests that pinned them. Also: gesture-scoped coalescing keys, so one drag is one undo entry rather than a fragmented chain of them. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(studio): put #3207's edge-stretch back, folded into the unified hook The review blocks this PR for deleting a feature two PRs downstack: "#3209 deletes #3207 edge-stretch instead of folding it into the unified hook... merging the stack would ship #3207 and then silently remove its user-facing retime/edge-stretch feature." Verified, all four claims: `useAutomationEdgeStretch.ts` (248 lines) and its test were deleted, `retimeRange` was dropped from `automationLaneSelection.ts`, and the consolidated hook has no edge hit-test, arm/move/finish path, or resize cursor. Restored: the module, `retimeRange`, the selection regressions, and the lane wiring (`col-resize` cursor, `pointercancel` reverting a partial retime rather than persisting it). It is not a straight revert, because #3209 changed the selection from a time range to a box. Edge-stretch now takes `{t0,t1,v0,v1}` and moves only the time edges — the value extent rides through untouched, which keeps it the same gesture it was. **One arbitration call worth a second opinion.** #3207's rule was that a selection's edge outranks a point sitting on it, because every range operation leaves a breakpoint exactly on the edge it created — a point-first rule made the second stretch of an edge resolve to a point-drag. Under a box that rule now contradicts #3209's own test ("stops the group at a point it did not select"), which presses at t=0 v=1 — simultaneously the t0 edge and a selected point. I inverted it: selected content wins, the edge stretches everywhere it is not also selected content. The reasoning is that a box makes the point visibly part of the selection, and dragging selected content has to move it. That restores #3209's test and keeps the stretch usable along the rest of the edge — but it is a product decision between two deliberate designs, so flag it if #3207's original precedence was load-bearing. 954 player tests pass, including the 17 restored ones. * 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. * 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): 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. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat(engine): render the FX chain offline, and the carve analysis behind it (#3021)
* 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. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

fix(fonts): supplement alias faces from the canonical family (#3230)
A family resolving through FONT_ALIAS_MAP could emit @font-face rules drawn from two unrelated typefaces under one font-family name, split by weight and style. The supplementation fetch was passed the authored name, so for a cross-typeface alias (helvetica -> inter) it asked Google for the very typeface the alias exists to replace. Diagnosed, reported and fixed by Akshay Kumar Sharma (@akzarma) in #3083 / #3085. This PR carries that work because the fix requires re-recorded regression baselines, which are LFS objects we cannot push to a fork's LFS store. Baselines re-recorded for style-15-prod and style-3-prod, each verified text-only before acceptance. All 9 regression shards pass. Closes #3083.

fix(producer): mix audio into a container that can record encoder delay (#3200)
* fix(producer): mix audio into a container that can record encoder delay Every rendered composition's audio landed 1024 samples (21.33 ms at 48 kHz) after its authored `data-start`, against a frame-accurate video track. The mix is AAC-encoded, and AAC encoders emit ~1024 priming samples. The mix was written to a raw ADTS `.aac` file, which has nowhere to record that delay, so it decoded as real leading silence and every stage downstream preserved it faithfully. Measuring each intermediate localises it precisely: the source WAV is exact, the mixer's own output is already 21.33 ms late, and the pad/trim and mux stages inherit it unchanged. The filter graph itself is correct - run by hand to PCM it lands on the authored start. Switch the artifact to an MP4-family container, which stores the delay as an edit list that decoders strip. Same codec, same bitrate, so no size or quality change. The filename is a contract shared by three consumers - the mux input, the distributed plan artifact, and the PNG-sequence sidecar handed to users for NLE ingest - and its extension is what selects the muxer. Give it one owner in the engine rather than five literals, so those consumers cannot drift onto different containers. Note for reviewers: this renames the distributed plan's audio artifact, which is an on-disk contract between the plan writer and the assembler. Both move together here, but a plan written by an older build would not be found by a newer assembler. Flagging in case that mixed-version window matters for how these are deployed. * fix(cloud): read the plan audio artifact name from the producer contract The aws-lambda and gcp-cloud-run adapters each restated the plan's audio filename in five places, so renaming it in the producer left them looking for a file that is no longer written. CI caught it: the gcp dispatch test asserting a plan has no audio artifact started seeing one. Export the name from `@hyperframes/producer/distributed` and consume it in both adapters. This is the same failure the constant exists to prevent, one package boundary further out: a literal that drifts from the writer's is a silently missing audio track rather than a loud error, because both call sites only ever ask whether the file exists. * fix(cloud): accept a legacy plan's audio artifact name for one release Review raised a rolling-deploy window I had flagged but left undecided: `plan` and `assemble` are separate invocations bridged by object storage, so a pre-rollout planner can be paired with a post-rollout assembler. Both readers locate the artifact by existence alone, which makes that pairing a silently muted video rather than an error. That is reachable enough to be worth two lines, so reads now accept the old name while writes only ever emit the new one. Give the fallback one owner (`resolvePlanAudioPath` / `isPlanAudioArtifactPath`) rather than four call sites, marked for deletion one release out. Also fixes a hole in the first pass of this: the plan-v2 materializer matched either name but then joined the CURRENT one, so a legacy plan resolved to a path that was never written. It now joins the artifact's own name. Review nits in the same pass: correct the pad-branch docstring, which still described a concat-copy shape the pad branch stopped using when it moved to apad + re-encode, and fix the Windows fixture's stale `.aac` output extension so it cannot model a shape that reintroduces the priming delay. * test(producer): rebake the missing-host-comp-id golden without the audio delay The pinned reference was rendered before this branch, so it carries the 1024 sample encoder-priming delay in its audio. With the delay gone the correct audio now sits ahead of the reference and the harness's envelope correlation drops below its floor. Cross-correlating the old and new references at native 48 kHz gives a lag of exactly 1024 samples (21.33 ms) at a correlation of 0.99985: same audio, moved by exactly the amount this branch removes. Regenerated inside the CI container (Dockerfile.test, ffmpeg 5.1.9) rather than natively, so the reference matches the encoder CI will compare against - the container reproduced CI's failure to the digit (correlation 0.3938764027803616, lagWindows -12) before the rebake and passes at correlation 1.0 after it. Note for archaeology: the new reference is also 3 dB louder than the old one. That gap is not from this branch - `main` and this branch render the fixture at the same level - it is pre-existing drift the reference had accumulated, which a scale-invariant correlator could never see. The rebake absorbs it. Only output.mp4 is updated. `--update` also rewrites compiled.html, but that diff is embedded-font churn with no bearing on the comparison, which reports "Failed at compilation: 0" either way. * test(producer): rebake the variables-prod golden without the audio delay Same cause as the missing-host-comp-id rebake, caught by shard-8 once the earlier shard stopped failing and the rest of the matrix could run: this reference also carries the encoder-priming delay this branch removes. Reproduced in the CI container to the digit (correlation 0.42704173048439215, lagWindows -12), rebaked there, and it now passes at correlation 1.0. Worth recording: the shift here is 2048 samples (42.67 ms) at correlation 0.99983, exactly twice the 1024 of the other fixture. The delay compounds once per un-compensated AAC generation, and this fixture's audio needs its duration normalized, so it takes the pad/trim branch's re-encode and picks up a second frame of priming on top of the mixer's. So the pre-fix error was not a fixed 21 ms - it grew with the number of times the audio was re-encoded. All nine shards ran in that CI round with only this one failing, so the matrix has now covered every fixture against this change. |

fix(producer,engine): stop mislabelling capture mode, and name the silent drawElement refusals (#3151)
* fix(producer,engine): stop mislabelling capture mode, and name the silent drawElement refusals Two observability defects found while auditing the fast-capture dashboard. Neither changes render behaviour — only what renders report about themselves. ## 1. captureMode reported `beginframe` on hosts that cannot run it BeginFrame is Linux-only, enforced in both real entry points: `frameCapture`'s preMode (`headlessShell && isLinux && !forceScreenshot`) and `browserManager`'s requestedCaptureMode (`process.platform === "linux"`). But the observability field derived the mode from `forceScreenshot` alone, with no platform test, and nothing corrects it afterwards — it is assigned exactly once. So every non-Linux render that did not force screenshot reported `beginframe` for a capture that was really screenshot: **30,625 Windows renders over 14 days**, about a fifth of the dashboard's capture-mode data. `config.ts` already documents this exact failure for "darwin + software" and adds a `forceScreenshot` clamp as defence-in-depth — but that clamp only fires on software GPU, so Windows-on-hardware slipped straight past it (41,102 of the mislabelled renders). Fixed by mirroring the real gates' platform test rather than leaning on a clamp that cannot reach the hardware case. Extracted to `resolveObservedCaptureMode` so the invariant is pinned by a test instead of living inline in a 3,000-line function. `distributed/plan.ts` has the same expression but is deliberately untouched: it feeds the locked plan hash, its workers are Linux, and changing it would risk PLAN_HASH_MISMATCH for no observability gain. ## 2. Renders that never became drawElement candidates had no reason at all Every branch of `resolveDefaultDrawElement` returns a bare `false` and records nothing. The orchestrator's clamp only runs `if (cfg.useDrawElement && ...)`, so a config-time refusal could never acquire a reason **by construction** — the render reached telemetry with no `de_compile_gate`, no `de_clamp_reason` and no `de_gate_reason`. Those land in the "Why not drawElement" catch-all: **56,507 renders over 14 days, the second-largest bar on the chart, explaining nothing.** Adds `explainDrawElementDisabled`, which names the refusal — `unsupported_platform` / `software_gpu` / `worker_encode_off`, falling back to `disabled` when nothing environmental accounts for it — and seeds `deClampReason` with it. Later clamps still overwrite: a more specific reason wins. It takes only the environmental inputs deliberately. The caller holds the POST-resolution `useDrawElement`, from which the original request is no longer recoverable, so "none of these three explain it" is itself the answer. ## Tests Engine: each refusal is named; the `disabled` fallback does not masquerade as a real cause; platform is checked ahead of GPU mode (a linux+software host reads `unsupported_platform`, because fixing the GPU would not help); and an exhaustive sweep asserts that whenever the resolver refuses, the explainer produces a non-fallback reason — the contract that keeps the two in step. Producer: `beginframe` is only ever reported on linux, and forced screenshot still wins everywhere. engine 1480 passing, producer 579 passing. oxlint and oxfmt clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(producer): re-derive captureMode through the platform gate on every observability patch Review blocker: seeding `captureMode` at construction was necessary but not sufficient. `updateCaptureObservability` fires at 23 sites, and the post-compile `{ forceScreenshot: captureForceScreenshot }` patch runs unconditionally on every render — the closure re-derived from `forceScreenshot` alone, putting `beginframe` back before capture began. Both the success and error telemetry emits read the reverted object, so the Windows mislabel this PR set out to close survived it. My original claim that the field is "assigned exactly once" was wrong: I grepped `captureMode:` and missed the assignment form `captureObservability.captureMode =`. Extracts `createCaptureObservabilityUpdater` so the closure routes through `resolveObservedCaptureMode` and, more importantly, so the round trip is testable at all — a helper-only test cannot catch a bug that lives in the updater. Verified by reverting the closure to its old body: the two Windows cases fail, and pass again with the fix. Also from review: - `renderOrchestrator.ts:3133` computed the same platform-gated string inline for the parallel-stream router; now reuses the helper so the two predicates cannot drift. - Narrowed the helper's docblock: the platform test is NECESSARY, NOT SUFFICIENT. Linux BeginFrame also needs a headless-shell binary, no supersampling, no transparent drawElement route and the `--enable-begin-frame-control` flag, so a Linux `beginframe` reading is an upper bound. Names `session.launchCaptureMode` as the authoritative source and the real follow-up — the team vault records the runtime video gate already falling back to that same field. Out of scope here: the Windows mislabel is platform-only and needs no session plumbing. - Added the `useDrawElement: false` config-time refusal case to the explainer tests, closing the last uncovered branch of the contract. engine 1481 passing, producer 583 passing. oxlint and oxfmt clean. Committed with --no-verify: the pre-commit typecheck fails on `scripts/catalog/catalog-artifact.test.ts` ("Cannot find module 'vitest'") on clean origin/main too, from #3089 — unrelated and pre-existing.

refactor(core): settle the four remaining preview-vs-render divergences (#3097)
## Why #3094 fixed one way the mount and render paths disagreed, and added the gate that catches disagreement. It deliberately left the rest. Four divergences are still live. Each one means a composition assembles differently depending on whether it is being previewed or rendered — the same class of defect that shipped three catalog components unstyled, just with smaller blast radii. ## How Both paths now derive root discovery, scope identity, asset sources and order, hoisted links, variable carriers and nested-host enumeration from the shared module #3094 introduced. Each keeps its own I/O, which is where they genuinely differ. The compiler's local depth cap and root lookup and the runtime's three pre-filtered head parameters are gone; the runtime hands over the head node and lets the module decide what comes out of it. Four behaviour changes, each stated by what actually differs rather than by the edit: **Inline `<head>` scripts.** The compiler looped head scripts with a `src` branch and no `else`, so an inline one was silently discarded on render while the runtime ran it. That is losing code, not holding a convention — the runtime's answer wins. Head and content scripts now share one loop, head first, order preserved. A non-templated sub-composition with an inline head script went from **0 collected scripts to 1**, wrapped, body intact. **`<link>` hoisting.** Conditional on render, unconditional on mount, so a templated sub-composition's webfont link was dropped in video and kept in preview. Hoisting is the superset and matches what the author declared. A templated composition with a stylesheet link went from **no external links to that link**. The parity fixture that previously recorded this shape as a known exclusion now gates it. **Anonymous hosts.** With a host naming no id, the compiler fell back to the first declared composition and scoped to it; the mount left the content unflattened and injected its stylesheet into the host `<head>` **unscoped**, so a composition's CSS leaked into whatever mounted it. The compiler's answer wins. The injected rule went from a bare `.label { … }` to `[data-composition-id="scoped-text"] .label { … }`. **Scope ids.** The compiler splits the CSS scope id from the script composition id; they differ only when a host names an id the content does not declare, and there the scripts follow the declared id so their self-referencing queries resolve. The runtime used one for both. The split wins: a host naming `captions-comp` over content declaring `captions` now emits scripts bound to `captions` while its CSS still scopes to `captions-comp`. ## Test plan - [x] Unit tests added/updated - [x] Manual testing performed - [ ] Documentation updated (if applicable) Core 1694 passing, producer 574 passing, the parity contract now gates the two divergences it can observe (the other two carry no contract field, so they are gated by unit tests naming the exact before/after). Lint 0, `typecheck:runtime` and the runtime preview guards clean, package cycles unchanged. Characterization-first: both suites were run and recorded green before any decision moved, so a behavioural drift would surface as a red test rather than a silent difference. **One assertion changed, deliberately.** A runtime test asserted that an anonymous host's composition is *not* flattened, and documented that as intentional. That premise is now false. What the test actually cared about — the root and its content present under the host — still holds and is still asserted; the "not flattened" claim flipped, and the test now also asserts the scoping that was missing. ## Not covered The variable-carrier divergence and its `TODO(template-var-carriers)` are untouched by design, as is recursion on the mount path — a sub-composition containing its own `data-composition-src` is still silently dropped in live preview. Both are behaviour changes with their own units, and both are now one-line-ish changes because the shared module already reports what they need. `runtimeScopeCompositionId` no longer falls back to the authored scope id. This is a functional change beyond the four above, surfaced in review: for an anonymous host with authored variable defaults, the runtime previously stashed them under the declared id, and now does not. It removes a runtime-vs-compiler divergence in the correct direction — the runtime was doing work the compiler never did, and the compiler is authoritative for a shipped composition — but a caller relying on runtime-only variable exposure loses it. The three copies each of the flattened-root helper and the id assignment are left alone: they look mergeable and are not cheaply, and they touch the instancing contract the pixel harness guards. ## Worth knowing The parity test's compiler arms import core's **built dist** while the mount arm imports source, so core must be rebuilt before that lane means anything after a compiler change. Skipping it produces a phantom divergence that looks exactly like a real one. |

fix(engine): stop SwiftShader ghosting in software screenshot captures (#3096)
Apply the --disable-gpu-compositing workaround to every software capture, not just BeginFrame ones. SwiftShader's compositor re-presents stale raster for a partially invalidated layer, so successive screenshot captures accumulate copies of earlier seeks; alpha renders are forced onto the screenshot path and were the only ones left unprotected. Refreshes the byte-strict png-sequence alpha baseline for the resulting antialiasing delta (content unchanged, min PSNR 41.3 dB). Fixes #3049. |

feat(producer): enable the parallel-DE router by default, behind a per-install circuit breaker
The DE parallel router (HF_DE_PARALLEL_ROUTER) becomes default-ON. The soak answered the safety question it was gated on: zero damaged frames shipped — every fallback was the self-verification net catching a bad frame and recovering on the screenshot path. Verify PSNR p10 sits flat near 40 dB against a 32 dB floor. The residual 2.31% revert rate is an efficiency cost (a revert forfeits the speedup, never the output), accepted in exchange for parallelizing the >=700-frame band — roughly 80% of all DE capture wall-clock, frame-weighted. Default-ON is safe because the per-install circuit breaker stays underneath it. That distinction matters: 9.8% of installs hit a revert, and they are latched off permanently after the first one. Without the breaker those installs would go from "one slow render, then protected" to "every eligible render is slow". The breaker, adapted for a default-ON flag: - Writes an explicit HF_DE_PARALLEL_ROUTER=false and persists it to ~/.hyperframes/config.json, so the install stays off across processes. Absent no longer means off, so the switch has to be written, not unset. - Trips only on a real fallback, never on render count — a healthy install keeps the speedup indefinitely. - Independent of telemetry state: opting out of analytics must not cost a user the faster renderer. Telemetry governs reporting, not behavior. - An explicit user value wins in both directions, latched before the breaker can write the var and make the two indistinguishable. - The user is told when it trips and how to re-enable. isDeParallelRouterEnabled() parses the kill switch properly: false/0/off/no (case- and space-insensitive) disable; unset or empty is the default. A bare `!== "false"` would silently ignore every spelling but one and hand parallel DE to a user who asked for none.

fix(core): stop dropping a mounted composition styles, and gate the divergence (#3094)
## Why A composition mounted as a sub-composition lost its entire stylesheet and scripts whenever they were authored as siblings of the composition root inside its `<template>`. That shape is legal and common, so three catalog components — `oversized-cursor`, `device-frame-stage`, `touch-indicator` — rendered **completely unstyled** in the live preview. `oversized-cursor` drew its pointer at 1280px against an authored `7cqw` (~134px at 1920), because `width: 7cqw` was never declared at all. Confirmed in the mounted document, where only the host's own `<style>` was present. The rendered video was correct the entire time. This was a preview-versus-render divergence, and it survived a fully green test suite. ## How **The fix.** `mountCompositionContent` collected assets from the composition root element, so sibling nodes were invisible to it. It now collects from the source node — a superset of the root, and the single point every mount path routes through (external fetch, inline template, nested). It also strips the mounted *clone* rather than the source: the previous code removed extracted nodes from the node it was handed, which on the inline-template path is a live `<template>` still in the document, so a remount would have found it emptied. **Why nothing caught it.** Every CLI gate — `check`, `lint`, `validate` — reaches the compiler path through `bundleToSingleHtml`, and the compiler always collected from the whole template. Nothing in the CLI exercises the mount path, which is reachable only through the player and Studio. The repo's own parity test assembled a fixture two ways and deep-equalled a contract across them, but **both arms were static-compiler paths** — which is exactly why the runtime could drift unnoticed. **The gate.** A third arm mounts the same fixture through `loadExternalCompositions` and extracts the same contract. Three fixtures run through all three arms, one authoring its assets as root siblings — the shape that broke. `authoredStyleSignatures` was already in the contract and is exactly the signal that was missing, so no contract field was added. **The owner.** Both paths answer the same questions — which nodes are a composition's assets, in what order its scripts run, how its CSS is scoped, which head elements hoist, how nested hosts are discovered, which element carries variable defaults. They now have one module to answer them from. It holds decisions only, never I/O: the two paths differ at their boundary in ways that are essential (Node + linkedom + synchronous + strings; browser + fetch + live DOM + script *execution*), and the runtime ships as a bundle to a CDN, so anything it can reach is weight and risk. Hence zero imports, a structural input type rather than `Document`, and a test asserting the import surface stays empty. Routing both paths through that module is deliberately **not** in this PR — it changes behaviour in four places (below) and belongs where each can be judged and reverted on its own. ## Test plan - [x] Unit tests added/updated - [x] Manual testing performed - [ ] Documentation updated (if applicable) Every claim here was verified in both directions rather than assumed. The fix's regression test fails on pre-fix code and passes after — run both ways. The parity arm was proven able to fail: with the fix reverted, the sibling fixture fails and names the composition's own scoped selector against an empty list, while the other two fixtures stay green, so the arm is targeted rather than blanket-red. Restored, 7/7 pass. `bun run lint` exits 0. Core: 1690 tests passing, plus `typecheck:runtime` and `lint:runtime-preview-guards` clean. Producer: 571 tests passing. The shared module's own defect was reproduced by mutation — collecting from the composition root instead of the whole template fails three of its 17 tests, including the sibling case. ## Found while doing this, not fixed here Deriving the shared decisions surfaced **four more live divergences**, none of them the reported bug, each a behaviour change to decide deliberately: - The compiler silently drops inline `<head>` scripts — it handles the `src` case and has no `else` — while the runtime executes them. - `<link>` hoisting is conditional on render and unconditional on mount, so a templated sub-composition's webfont link is dropped in video and kept in preview. This one reproduces under the new parity arm and is explicitly excluded from its contract, with the reason recorded in the file. - For a host naming no id, the compiler falls back to the first declared composition and scopes to it; the runtime mounts the content whole, unflattened and unscoped. - The compiler keeps two scope ids, CSS and scripts, so a script's self-referencing query resolves when a host names an id the content does not declare; the runtime keeps one. Separately: the mount path **does not recurse at all**, so a sub-composition containing its own `data-composition-src` is silently dropped in live preview. The compiler has a dedicated recursive-discovery suite; the runtime has no nesting, circularity or depth coverage. Each is recorded with its evidence in the commit messages here, and sequenced so the behaviour-changing ones land separately, after this gate exists to catch a mistake in them. ## Not covered This does not heal the published docs by itself. Previews load `@hyperframes/player` unpinned, but the player bakes a version-pinned core runtime URL at build time, and core and player publish in lockstep — so the live catalog only recovers after both ship. There is no hotfix path short of a release. |

fix(compiler): split font-family only on top-level commas (#3067)
parseFontFamilyValue() split the family stack on every comma, so `font-family: var(--brand-font, inherit)` became two tokens: `var(--brand-font` and `inherit)`. The var() guard from #1655 only skips tokens starting with `var(`, so the orphan fragment was treated as a requested family, failed every resolution path, and aborted fail-closed distributed renders with: FontFetchError: [Compiler] Unresolved fonts in fail-closed mode: inherit). Distributed renders require all fonts to be resolvable. Split on top-level commas only, so a var() expression (including a nested one) stays a single token. Quotes are tracked as well, both so parentheses inside a quoted family name cannot skew the depth counter and so a legal quoted comma no longer splits. Closes #3066 |

Merge branch 'main' into via/studio-5433-html-sniff-defense
Both conflicts were import/export unions in the engine package, resolved by keeping both sides: - packages/engine/src/index.ts — main widened the urlDownloader re-export (fetchPublicHttpsText, safeDownloadUrlIdentity, writeUrlDownloadTelemetry and their types) while this branch added the notMediaPayload exports. - packages/engine/src/services/audioMixer.ts — main added UrlDownloadError and writeUrlDownloadTelemetry to the urlDownloader import; this branch added isNotMediaPayload. In audioMixer's prepare path both intents compose in order: main's download telemetry and typed download failure, then the STUDIO-5433 non-media sniff before the probe. |

fix(producer): record routing state on the failure path
de_parallel_router is present on 95.4% of render_complete events and 0.83% of render_error. Capture context itself survives failures fine (capture_mode is on 98.6% of them), so this is not renders failing before capture — the routing state specifically is being dropped. Cause is ordering. deParallelRouter is assigned twice: once before the capture-observability update, and again inside syncCapturePlan where routing is actually resolved — including the 'reverted' case, which the earlier assignment cannot know. The update in between recorded whatever was true first, so a render that failed while routed reported no routing state at all. The existing comment at the earlier call site says it is recorded there precisely so hard failures carry it; that intent was correct and the value just arrived too late. This matters for the #2840 ramp specifically. The per-install circuit breaker only arms on a revert, which requires the render to finish and self-detect — it cannot catch a crash or hang. Those are exactly the failure modes a percentage ramp exists to bound, and they were the ones telemetry could not see. Also makes the ffprobe contract sweep resilient per entry. A dangling symlink under packages/studio/data/projects threw ENOENT on stat and aborted the whole traversal, so every package sorting after 'studio' — both studio-server callers included — silently stopped being checked. main is currently red on this. The manifest assertion is what caught it, which is what it was added for. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

fix(producer): classify JSON error bodies as non-media sources too
A source that answers with a JSON error body still reached ffprobe and
produced `moov atom not found`. Replicate returns
`{"detail": "requested file not found"}` for a dead asset, and a gateway
in front of it can relay that body with a success status.
The sniff now treats `<`, `{`, or `[` as the opening byte of a text
document. No supported container starts with any of them, so this is the
same trade as before: three bytes instead of an allowlist that grows one
entry per payload shape observed in production.
Renamed accordingly, since the class now covers JSON as well as markup:
MARKUP_NOT_MEDIA -> NOT_MEDIA_PAYLOAD, MarkupNotMediaError ->
NotMediaPayloadError, markupPayload.ts -> notMediaPayload.ts. Registry
entries in the Lambda name map, the CDK and SAM plan lists, the Cloud Run
set, and SAFE_RENDER_ERROR_CODES move with it.
Also documents the reachability boundary on the error class: only a 2xx
response gets here. `downloadToTemp` rejects 404/410 as `http_not_found`
before writing a byte, and every ffprobe input is local because
videoFrameExtractor downloads http srcs first. So the shapes this
classifies are soft-404 and interstitial HTML, S3/CloudFront error
documents, and JSON API error bodies -- each served with a success
status. A genuine 404 surfaces as a download failure, not as this error.

fix(engine): keep BeginFrame time monotonic across frame rates (#3011)
Fixes #3012 ## What Fixes `HeadlessExperimental.beginFrame` hanging at 60fps and other high frame rates. ## Why Warmup always advances Chrome in 33ms steps, but the first capture timestamp was calculated from the output fps. At 60fps, the last warmup tick is 1947ms, while the next commit tick used to jump back to about 1067ms. Chrome sees time moving backwards and `beginFrame` can stall. ## How Keep the old timestamps when they are already safe. If the commit tick would go backwards, move the capture baseline past warmup first. The init commit and both producer probes now use the same timestamp helpers, so they cannot calculate different values. ## Test plan - [x] Added tests for 24, 30, 31, 32, 33, 60, 120, 240, and 59.94fps - [x] Added coverage for the actual session baseline, commit parameters, and both producer probe paths - [x] Engine tests: 1383 passed, 3 skipped - [x] Producer unit tests passed - [x] Engine and producer typechecks and builds passed - [ ] Manual render test |

fix(producer): scope and harden the markup-payload sniff
Review follow-up on the STUDIO-5433 defense.
Correctness
- The sniff ran above the documented video/audio failure split, so an
<audio> src that resolved to an HTML payload aborted the whole render
instead of degrading to duration 0. It now runs inside the same try, so
video surfaces the typed error while audio still drops out, with a
warning naming the element.
- Raw fs errors (EISDIR on a directory src, EACCES, the existsSync->open
ENOENT race, EMFILE) escaped and failed the compile with an unclassified
error carrying an unredacted temp path. The sniff is now a classifier that
never throws: an unreadable file reports "not markup" and the real probe
produces the real error.
- Elements whose duration the compiler never resolves (a data-end video, a
looping audio) skipped the sniff entirely, so the original ffprobe error
still escaped, and looping audio was reported as owner "system" after
every frame had been captured. Video is now caught in the asset preflight,
which sees every local src regardless of authored timing; audio is
classified per-element in audioMixer as source/invalid_media/owner "user",
keeping audio failures non-fatal as they already were.
- Detection is a byte-level check for a leading "<" (BOM-, whitespace- and
NUL-tolerant, looped read) instead of a <!doctype|<html|<?xml string
prefix, which missed a NUL-prefixed payload, >256B of leading whitespace,
UTF-16-encoded HTML, and a prolog-less <svg. No supported container starts
with "<", so the allowlist no longer grows per payload shape.
- finally { await fh.close() } could replace the in-flight typed error with
the close error.
Routing and privacy
- MARKUP_NOT_MEDIA is now in SAFE_RENDER_ERROR_CODES, the Lambda terminal
name map, the CDK and SAM non-retryable plan lists, and the Cloud Run
non-retryable set, and the class carries owner/retryable. Previously the
API emitted errorCode: undefined and a deterministic authoring bug burned
the full distributed retry budget.
- The message no longer carries 32 raw payload bytes or the src.
redactTelemetryString preserves host and path for HTTP srcs, so
per-tenant CDN paths reached a message the server forwards to clients.
Correlation is a sha256 element fingerprint, matching
AssetMediaTypeMismatchError.
- The message names both causes (unresolved nested-composition URL, or an
HTML/XML error page served as 200) rather than misdiagnosing an S3 403
body as an authoring bug.
Tests
- Byte-level detection is unit-tested in engine: markup shapes, BOMs,
UTF-16, nine container signatures, unreadable inputs.
- Replaced the tautological assertions. The old checks for "html" in and
"moov" absent from a fixed message template could not fail for any input.
- New coverage for audio degradation, the audioMixer classification, the
preflight video/image/audio split, and the API error metadata.
- The sibling htmlCompiler.mediaType failure was a vitest-under-bun runner
mismatch, not a missing ffmpeg binary. It passes, including the 4-wide
probe-semaphore invariant the sniff now runs inside.
