Moving sharp and onnxruntime-node to optionalDependencies (in the earlier
capture/native-module hardening) regressed `remove-background` from ~7% to
~97% failure starting at 0.6.101: the command genuinely *requires* both native
modules, but as optional deps they're skipped on most installs, so it hits the
guarded "module not available" error and fails for nearly everyone.
The capture crash that motivated the optional move is already fixed by the
lazy, guarded `await import()` in contentExtractor / inference — that holds
regardless of dependency classification. Making the modules optional was the
over-correction; the lazy import alone was sufficient. sharp ships its own
platform binaries as optional sub-deps, so it installs cleanly as a hard dep
without failing installs on unsupported platforms (it was a hard dep at 0.6.99
with remove-background at a healthy ~7%).
- Move sharp + onnxruntime-node back to `dependencies` (so they install for
everyone again). `@google/genai` stays optional — genuinely optional, lazy,
and not part of the regression.
- Keep the lazy guarded imports — they remain the crash-safety for capture.
- Add trackCommandFailure to remove-background's catch: it self-exits, so the
dispatch wrapper never saw it (the reason stream was blind). Now its failures
carry a reason, closing that command from the wrapper-blind follow-up.
remove-background tests + background-removal suite pass; tsc clean; build green.
Studio-triggered renders emit render_complete / render_error from the CLI
preview-server process, which stamps every event with the install's
anonymousId (client.ts drainQueueToPayload). The browser, meanwhile, fires
studio_session_start / studio_render_start under its own getAnonymousId(). So
the render outcome and the render start never share a person_id — verified in
data: of 15,125 users who started a studio render in 30d, ZERO have any
render_complete under any source, and the 898 studio-tagged completers are
disjoint server UUIDs. The studio render funnel — the product's core value
moment and strongest retention signal — is therefore unmeasurable.
Thread the browser's telemetry id through to the render-outcome events:
- client.ts: trackEvent takes an optional distinctId; drainQueueToPayload uses
`event.distinctId ?? config.anonymousId`. CLI renders unchanged.
- events.ts: trackRenderComplete/trackRenderError forward an optional distinctId.
- studioRenderTelemetry.ts: emitStudioRender* pass opts.distinctId through.
- core studio-api (types.ts + routes/render.ts): the render route reads
`telemetryDistinctId` from the request body (validated string) and passes it
to the adapter's startRender, which already forwards opts to the emitters.
- studio (useRenderQueue.ts): include getAnonymousId() as telemetryDistinctId
in the render POST — the same id studio_* events already use.
Result: studio render_complete/error now carry the browser user's id and join
studio_session_start / studio_render_start. Older clients that don't send the
field fall back to anonymousId (no regression). No new tracking surface — it's
the existing anonymous studio id.
Tests: per-event override forwarding (events), studio render distinctId
threading + older-client fallback (studioRenderTelemetry), and route body →
adapter forwarding incl. non-string rejection (core render route).
Observability showed `browser` (~75% fail, ~1.3k users/day) and `info` (~60%
fail) failing at high rates with no captured reason — only
`cli_command_result success=false`. citty's `runMain` catches a command's
thrown error and `process.exit(1)`s without re-throwing, so a thrown failure
never reached the existing `cli_error` telemetry (which only fired from the
uncaughtException / unhandledRejection handlers).
Wrap every command's `run()` at the dispatch boundary (cli.ts) so a thrown
failure reports its reason via `cli_error` (kind=command_error) before being
re-thrown unchanged — citty's print + exit-1 behavior is preserved. This
de-blinds every throw-style command at once: `browser ensure` (Chrome
download), `tts`, `inspect`, `render`, etc.
Paths that bypass the wrapper are handled inline:
- `browser` self-exits (`path` download failure, unknown subcommand) — report
inline; the ARM64 `ensure` branch previously swallowed a failed install and
returned success, now reports and exits 1.
- `resolveProject()` self-exits on InvalidProjectError (the dominant `info`
failure — run outside a project) — report inline before exit.
Hardening:
- PII: `trackCliError` now redacts error_message + stack_trace via
redactTelemetryString (matching render_* events) — CLI errors and stacks
carry absolute install paths / cache dirs / user args.
- Race: the wrapper awaits an on-demand telemetry import before re-throwing, so
a command that fails before the lazy telemetry import settles still reports
(a telemetry failure is swallowed and never masks the real error).
Pure helpers in utils/command-failure-tracking.ts with unit tests for the
throw / success / no-run / onFailure-rejection cases, the reporter wiring, and
trackCliError redaction. CommandDef<any> mirrors citty's SubCommandsDef.
Known scope: commands that print + `process.exit(1)` on their own validation
paths (tts/validate/lint argument errors) remain wrapper-blind — follow-up.
* feat: add video frame format render option
* refactor: single source of truth for video-frame-format allow-list
Addresses PR review (Via) on #1481: the ["auto","jpg","png"] set was
declared three times — render.ts (VIDEO_FRAME_FORMATS), server.ts
(inline includes), and renderConfigValidation.ts
(ALLOWED_VIDEO_FRAME_FORMATS) — three boundaries to update when a new
extraction format lands.
Hoist the constant + a reusable `isVideoFrameFormat` type guard into
@hyperframes/engine (where VideoFrameFormat is defined) and route all
three call sites through them. Behavior unchanged; also drops two
`as RenderConfig[...]` casts in favor of the guard (narrowing over
assertion, per repo TS conventions).

* feat(cli): support OpenRouter as an alternative vision provider for capture captioning
`hyperframes capture` could only enrich asset descriptions with Gemini vision,
which requires a Google API key. Add OpenRouter as an alternative so users
without Google access can caption via any vision-capable model through one
unified key.
Provider is selected by which key is present: OPENROUTER_API_KEY → OpenRouter
(OpenAI-style /chat/completions with an image_url data URI), else
GEMINI_API_KEY/GOOGLE_API_KEY → Gemini (unchanged), else DOM-only as before.
OpenRouter wins if both are set. Default model is google/gemini-3.1-flash-lite
(the OpenRouter analog of the Gemini path's existing 3.1-flash-lite tier),
overridable via HYPERFRAMES_OPENROUTER_MODEL.
Both vision call sites — the image loop and the rasterized-SVG loop — route
through a single `captionOne` dispatcher, so the new provider works for SVGs too
(the original PR #840 only patched the image loop, which would have left
OpenRouter-only users with crashing SVG captioning). The OpenRouter path checks
res.ok and surfaces the status/body on failure.
Reimplements #840 (which was unmergeable: saved with a UTF-8 BOM + CRLF so
GitHub rendered it as a binary diff, used `any`, reused the Gemini model env
var, and had a hallucinated default model id).
- Adds unit tests for the OpenRouter path (happy path, graceful degradation on
non-OK status, no-key skip).
- Documents OPENROUTER_API_KEY in the website-to-video guide and the CLI capture
reference.

* test(cli): fix typecheck in OpenRouter caption test — capture request without `as`
The test cast `fetchMock.mock.calls[0]` to a tuple (TS2352: `[] | undefined`
doesn't overlap `[string, RequestInit]`), which failed the Typecheck CI job.
Capture the url/init inside the typed mock and assert via `new Headers()` +
`typeof` narrowing instead — no `as` assertions (which the repo bans anyway).

Transcribe failures are recorded as `cli_command_result success=false` but
without a reason: the command catches its own error, prints it, and
`process.exit(1)` — the message never reaches telemetry. `cli_error` was only
emitted from the uncaughtException / unhandledRejection handlers, so
self-handled command failures were invisible. That makes a high failure rate
countable but not debuggable.
Add `trackCommandFailure(command, err)` — a thin wrapper over the existing
`trackCliError({ kind: "command_error" })` that normalizes an unknown reason to
name/message/stack. It enqueues synchronously, so the process `exit` handler's
flushSync ships it alongside `cli_command_result`. Respects the telemetry
opt-out (gated in trackEvent) and reuses the existing PII redaction.
Wire it into all three of transcribe's failure exits (file-not-found,
empty-transcript import, and the transcribe() catch — ffmpeg / whisper-binary /
model-download errors). Now each failure carries its reason, so we can see how
much of the failure rate is environment vs user input.
The helper is generic — the same one-liner can be dropped into other commands'
failure paths, or centralized at the runMain boundary, as a follow-up.
Aimed at `npx hyperframes` users (standalone and inside monorepos), where the
native modules `sharp` and `onnxruntime-node` can't install or load.
## Native modules are now optional, and never abort the CLI
`sharp` and `onnxruntime-node` are native modules: their platform binaries ship
as optional sub-dependencies that can fail to land on end-user installs
(--omit=optional, musl/glibc, monorepo hoisting, cross-platform lockfiles,
broken npx cache). Both powered only optional commands, yet both were wired as
hard `dependencies`, so on any platform where a binary can't install the whole
CLI failed to install. Moved both to `optionalDependencies` (alongside
@google/genai) so the core CLI always installs; the native-accelerated paths
light up only when present.
Runtime handling so a missing/unloadable binary degrades instead of crashing:
- `capture` (`contentExtractor.ts`): sharp was a static top-level
`import sharp from "sharp"`, so a load failure threw on module import —
before the inner try/catch — aborting the whole command. Now a guarded lazy
`await import("sharp")` that skips SVG captioning with an actionable warning.
Marked `external` in tsup so esbuild never bundles the native module.
- `remove-background` (`inference.ts`): both `onnxruntime-node` and `sharp`
are loaded here and genuinely required. The dynamic imports are now guarded
to throw an actionable "install / reinstall with optional deps" error
(surfaced cleanly by the command's existing try/catch) instead of a raw
"Cannot find module". New tests assert createSession rejects with that
guidance — before touching the model download — when either module is
unavailable.
`contactSheet.ts` also uses sharp but is already behind a dynamic-import
boundary wrapped in try/catch, so it was never a hard-fatal path.
## inspect: content-overlap as a warning, not a blocking error
The `content_overlap` layout-audit check shipped as `severity: "error"`, and
the audit exits non-zero when `errorCount > 0`, so `inspect` failed for
compositions that intentionally layer text. Downgraded to `severity: "warning"`
so it still reports (and prints the `data-layout-allow-overlap` opt-out hint)
without breaking exit codes. Reversible.
PR #1447 added `capture video` as a citty subCommand. citty's runCommand
(node_modules/.bun/citty@0.2.2/.../dist/index.mjs:209-227) treats any non-flag
positional as a subcommand-name attempt and throws E_UNKNOWN_COMMAND when it
doesn't match — there's no fallback to the parent's positional args, so
`hyperframes capture https://vercel.com` died with "Unknown command https://vercel.com".
Per James's suggestion, surface video-download as `capture --video <project>`
(a mode flag) instead of a subcommand. Citty has no issue with a positional
URL coexisting with flags. `video.ts` now exports `runVideoMode()` instead of
a `defineCommand` default export.
- `hyperframes capture <url>` works again
- `hyperframes capture --video <project> --index N` downloads video
- `hyperframes capture --video <project> --list` lists manifest
- `hyperframes capture --video <project> --video-url <url>` downloads by URL
Extend `inspect` to verify motion intent against the same seeked timeline
the renderer uses, catching render-≠-preview bugs that layout sampling can't:
entrance reveals the seek skips, broken stagger order, off-frame drift, and
frozen shots.
A `*.motion.json` sidecar next to the composition opts in (auto-discovered,
no flag, no authoring-framework changes); without one, inspect is unchanged.
inspect seeks a dense grid over the asserted selectors, builds an
element × time matrix of {rect, opacity, visible} plus per-scope liveness
signatures, and evaluates four assertions in Node:
appearsBy -> motion_appears_late
before -> motion_out_of_order
staysInFrame -> motion_off_frame
keepsMoving -> motion_frozen
A selector matching nothing is reported as motion_selector_missing rather
than silently passing. Findings reuse the LayoutIssue shape and flow through
the existing dedupe/collapse/limit/format pipeline and JSON envelope; they
are errors by default, so a failed assertion fails the run.
The motion pass runs in the same Chrome session as the layout audit (no extra
launch) and only when a sidecar is present.
Make /hyperframes the single entry skill and bring the docs back in sync with
the #1349 skills refactor.
Skills:
- Rename hyperframes-read-first -> hyperframes so the leaderboard-tracked
/hyperframes is the entry/router skill; description leads with "READ THIS
FIRST" to preserve the read-first intent. Update all references across
CLAUDE.md, AGENTS.md, CLI templates, test script, and workflow SKILLs.
Docs (closes the quickstart confusion in #1428):
- quickstart + prompting: replace the dead standalone runtime slash commands
(/gsap /lottie /three /waapi /animejs /css-animations /tailwind) with the
real surface; document the picker as required core skills (8) vs optional
workflows, with --all as the install-everything shortcut.
- frame-adapters: map every runtime to /hyperframes-animation.
- packages/cli: /tailwind -> /hyperframes-core; rewrite the skills-include
blurb around the current domain skills.
- copilot-cli/pipeline/migrating-to-lambda: /hyperframes is the router; the
composition contract lives in /hyperframes-core. Fix a dead /gsap example.
- antigravity: stop listing gsap/ and tailwind/ as separate skill dirs.
- contributing/catalog: /contribute-catalog -> /hyperframes-registry.

The layout audit only reported boxes that overflow their container; text
that fits perfectly but is painted over by a later sibling or overlay was
never caught. Add a text_occluded check that sweeps a grid across each text
box (three rows x nine columns) and, via elementFromPoint, flags text whose
topmost element is an unrelated opaque element (raster content, background
image, or a solid background at near-full opacity). Low-opacity overlays
such as scrims and grain are exempt. Opt out of intentional layering with
data-layout-allow-occlusion.
The two *.browser.js audit scripts are added to the fallow entry list: they
are injected by path via page.addScriptTag, so they have no import-graph
referrer.

For the hyperframes.dev website-to-video flow. Real-AI-test runs against
heygen.com, huly.io, and heygen-showcase surfaced two gaps: (1) capture's
logo / asset-captioning signals missed modern React/Tailwind builds; and
(2) there was no CLI surface to pull the videos the manifest references.
New command:
• `hyperframes capture-video <project>` — on-demand downloader for
entries in capture/extracted/video-manifest.json. Capture writes the
manifest + preview PNGs but skips the mp4s; this pulls one entry by
`--index N` (matched against the entry's `index` field, NOT array
offset — gaps are possible when a preview screenshot fails). SSRF-safe
via safeFetch, 250 MB cap, content-type whitelist, race-free
exclusive-create write. Layout-aware (handles both standalone capture
and W2H project layouts).
Capture pipeline fixes:
• Structural logo signals (assetCataloger + tokenExtractor): inBanner /
inHomeLink / matchesTitleBrand. Class-substring alone caught 0/32 SVGs
on heygen.com — modern builds don't put 'logo' / 'brand' in any
className.
• Content-hash SVG slugs (assetDownloader): `svg-<8char-sha1>.svg` —
label-derived slugs mis-attributed partner-logo carousels
(heygen-logo.svg actually contained Google, hubspot-logo.svg contained
Trivago, etc.). Content-hash names are invariant by construction.
• SVG → PNG rasterization before Gemini Vision (contentExtractor): the
raw-SVG-as-text path was hallucinating wordmarks (VIVIENNE for HubSpot,
'wrestling' for Workday). Adds polarity detection so a white-glyph SVG
flattened to a blank PNG gets inverted before captioning. LOGO tag in
asset-descriptions.md when structural signals fire (independent of
Gemini key presence).
• Double-escape \/ inside the page.evaluate template literal in
assetCataloger + tokenExtractor: the original `/^https?:\/\/.../`
collapsed to `/` mid-template and threw `Unexpected token ^`. Capture
was 100% blocked on this until the escape was fixed.
• `asset-descriptions.md` header branches on Gemini-key presence with
an explicit 'Vision OFF — catalog-derived descriptions' warning.
New lint rule:
• `lintMissingLocalAsset` (cli/utils/lintProject): scans <video> / <img>
/ <source> src for local files that don't exist in the project.
Empirically the most common sub-agent mistake across multi-URL runs
(~5+ per run). Uses `resolveExistingLocalAsset` so the existence check
matches the bundler's notion of 'resolves'. Masks comment / style /
script ranges before scanning so a literal `<img src=missing.png>`
inside a tutorial comment isn't reported.
Tests: 17 new for capture-video (safeFilename decoding/sanitization,
VIDEO_CONTENT_TYPE_RE accept/reject, pickManifestEntry index-field lookup
with gaps, URL-mismatch + bad-index rejection, --index over --url
priority); 70 cases under lintProject.test.ts covering the new rule and
existing rules.
Sibling PRs in this stack:
• #PR_A1 — fix(producer): __dirname ESM banner shim
• #PR_A2 — fix(core/lint): findRootTag masks comment/style/script
The layout audit compares each element against its container, so two text
blocks that collide with each other — neither overflowing its own box —
render unreadable yet pass clean. Add a content_overlap check that pairs up
the solid text blocks and reports any two whose boxes intersect by more than
a fifth of the smaller box. Watermark-style text (low colour alpha) is
decorative and exempt; opt out of intentional stacking with
data-layout-allow-overlap.

* feat(studio,cli): music beat detection with timeline guides + headless beats CLI
Beat detection for music tracks: the Studio draws beat guides on the active
track, beats are user-editable and persist to a project file, and a new
`hyperframes beats` CLI generates that file headlessly before the Studio opens.
Detection lives in @hyperframes/core/beats (shared by Studio + CLI): an energy
onset detector cross-validated with bpm-detective, regularized to an octave-
aligned grid, silence-gated, with per-beat loudness. Music-only — an
<audio data-timeline-role="music"> is analyzed; voiceover is excluded.
Studio: green beat lines + draggable dots on the selected track; add at playhead,
drag to move, double-click to delete (audio scrubs); edits persist to
beats/<audio>.json and are undoable (interleaved with file history).
CLI: `hyperframes beats [dir]` runs the same detection in headless Chrome
(prebuilt browser bundle in dist) and writes the beat file.

* feat(studio): timeline beat-grid + zoom UX refinements
- Center-anchored magnify: zooming via the toolbar/slider keeps the time
at the viewport center fixed instead of anchoring at the left. Pinch
still anchors at the cursor.
- Move-snap to beats: dragging a clip snaps whichever edge (start or end)
is nearest a beat, matching the existing resize-edge snapping.
- Beat lines on track backgrounds: faint full-height beat lines now paint
behind the clips on every track lane (brightness scales with loudness);
the green dots stay on the active track's top bar.
- Waveform follows zoom: bars fill the full clip width and resample the
windowed peaks, so the waveform stretches with zoom instead of stopping
partway across a widened clip.
- Beat dots centered in the top bar: align the dot band to the clip top
(CLIP_Y) so the dots sit centered in the dark bar instead of being
bisected by the clip's top border.

* fix(studio): preserve media sourceDuration across element re-derivation
Moving a non-music clip re-derived the timeline elements into fresh
objects whose sourceDuration the DOM scan hadn't loaded yet. The async
probe skips srcs already in its cache, so the value was silently
dropped — trimFractions then returned no window and the trimmed music
waveform reset to the full source pinned at the track start.
Re-apply the cached probe duration synchronously on every derivation
(applyCachedSourceDurations) and extract the async probe loop into
probeMissingSourceDurations to keep useTimelinePlayer within the file
size limit.

* feat(studio): skip beat-snap on the music track, highlight move-snap target
The music track defines the beats, so moving or trimming it no longer
snaps to its own beats (isMusicTrack guard on both the move and resize
snap paths).
Moving another clip snapped only on drop with no cue. snapMoveStartToBeat
now also returns the beat it will snap to; BeatBackgroundLines draws that
beat's line as a bright neon-green glow while the clip's edge is within
the snap region, so the target is visible before drop.
Also drops .commitmsg.tmp, accidentally committed via git add -A.

- Beat dots render on the selected track, falling back to the music track
when nothing is selected.

* fix(studio,core,cli): review hardening for beat detection + timeline UX
- playerStore.reset() now clears beat state (analysis, edits, undo/redo,
persist) so a project switch can't apply the previous project's beats,
undo stack, or file-writer to the new one.
- removeUserBeat returns the same reference on a no-op, and delete/move beat
actions skip committing when nothing changed — no more phantom undo
entries / debounced writes for no-op edits.
- regularizeBeats bails to raw onsets when the (octave-misread) tempo would
produce a sub-125ms grid, avoiding a tens-of-thousands-of-beats freeze.
- parseBeats clamps strength to [0,1] and rejects non-finite time/strength,
so a hand-edited file can't feed NaN into the gamma curve (Math.pow on a
negative base) and blank out beat markers.
- Start-edge beat-snap now also requires duration >= minDuration, matching
the end-edge guard, so a rightward snap can't collapse the clip.
- Center-anchor zoom effect always consumes its skip flag, so a pinch that
produced no pps change can't leave it stranded and skip the next zoom.
- Headless beats analyzer projects to {beatTimes,beatStrengths,bpm,confidence}
before returning, so page.evaluate no longer serializes the full decoded
PCM (channelData) across the CDP boundary.

* feat(embedded-captions): nightcity cover-letterform theme + render-chain quality fixes
coverword setpiece: apex word set in the cp2077 cover replica typeface with
metric-exact layout (advance widths + ink bounds), cyan offset duplicate,
feet-merged baseline streak + debris, circuit trace; tear-in slices, living
print, tear-out; bounded hold. cpslam kept in the setpiece registry.
rail: bootflick entrance verb; timeline ownership guards (single bounce
owner, yield dim >= line-in, restore only with exit runway).
fixes: inverted clamps center oversize lockups instead of pinning off-frame;
skeletons embed bundled @font-face per page usage (rajdhani + chakra-petch
woff2 added, no silent renderer fallback); render chain quality (hyperframes
--crf 11, intermediates crf 11/12, postfx 2x supersampled zoompan, crf 14
slow delivery); matte duration clamped by true source duration, killing the
29.97fps trailing black frames.
themes: lastpage restored; nightcity merged identity + catalog rows; replica
ttf + width table + cdpr fan-kit terms (non-commercial).

- oxlint: unused catch bindings -> optional catch, reflow expressions
void-prefixed, unused vars underscore-prefixed (64 sites, 12 files)
- skill.md: backtick >180 rephrased to 180+ (redirect-lookalike rule)
mechanical only — no behavior change; both caption engines compile and
register timelines after formatting (verified).

* fix(skills): route audio.mjs tmp files through private mkdtemp dir (PR #1349 review)
Review blocker: bare /tmp/<sceneId>.txt + /tmp/bgm-<ts>.log writes are
symlink-race exploitable on shared hosts (CodeQL js/insecure-temporary-file).
New scripts/lib/scratch-dir.mjs (x3 forks, byte-identical) lazily mkdtempSync's

Doc sync: guide.md bgm_log shape, finalize-agent/preflight /tmp/bgm-*.log refs
(actual path still flows via audio_meta.json, downstream unaffected).
Also from the same review:

- .fallowrc.jsonc: ignore skills/motion-graphics/{grounding,categories}/** —
agent-invoked tools co-located with their docs, not import-graph reachable;

- check-compositions.mjs x3 forks: <style>/<script> block extraction now

browsers actually parse — closes js/bad-tag-filter (a composition could
previously hide script/style content from the contract gate).
- build-design.mjs x3 forks + pr-to-video ingest.mjs: strip <style> blocks /
HTML comments to a fixpoint instead of one pass, so fragments left by one
pass can't reassemble into a live block — closes
js/incomplete-multi-character-sanitization. (Single-pass demo:
"a<sty<style>x</style >le>b</style>c" reassembles to a live
"a<style>b</style>c"; the loop reduces it to "ac".)

'</script\t\n bar>' and '</script/>'. Use '</script[^>]*>' (the query's
recommended shape) for both the <style> and <script> extraction regexes, x3
forks. Verified all four closer variants now terminate a block.

* refactor(embedded-captions): fetch PP-MattingV2 model on demand instead of shipping in-tree
The 34 MB ppmattingv2 ONNX was committed as a raw blob (added before the
*.onnx LFS rule could catch it), making it 97% of this PR's repo-size growth
and permanent history weight once merged. Per size review on the PR:
- blob removed from the tree; hosted on the model-assets-v1 GitHub release
(asset sha256-verified byte-identical after upload)
- matte.cjs resolves: MATTE_MODEL env -> legacy bundled copy if present ->
~/.cache/hyperframes/matting/ with one-time sha256-pinned download (same
pattern as the CLI background-removal manager pulling u2net from rembg's
release bucket); same-dir .part temp + atomic rename
- new `matte.cjs --ensure-model` pre-warm flag; SKILL.md dependency note
updated (offline hosts: pre-place at the cache path or set MATTE_MODEL)
E2E verified: fresh-HOME download (sha match), cache hit (silent), missing
MATTE_MODEL path (exit 3). Author-time fetch only — render path untouched.
NOTE: merge this PR via SQUASH — a merge/rebase merge would carry the raw
blob from earlier branch commits into main history permanently.

* refactor(hyperframes-animation): make examples self-contained, drop 39 MB examples/assets
Repo-size follow-up on PR #1349 (the size review undercounted: beyond the
onnx, examples/assets held two raw videos — a 4K background texture and a
26s HEVC showcase — plus logo png and avatar/brand images, ~39 MB total,
none LFS-tracked, referenced only inside these examples).
- assets/ deleted outright; no external path coupling (verified).
- 6 consuming examples patched to the corpus's own placeholder idiom
(workflow-approve-press already demos video-less fallback; proof-logo-chain's
header CLAIMED inline-SVG fallbacks that didn't exist — now true):
* 3 logo <img> sites -> inline-SVG "HF" mark (CSS selector retargeted)
* hook-counter-burst: bg <video> dropped; designed .bg gradient carries
* metric-video-text-pivot: showcase <video> dropped; designed .video-scene
carries; escaped <video> re-add snippet kept as a comment (literal
<video in comments trips the lint media scanner)
* proof-logo-chain: avatars -> CSS initials circles (deterministic
index-derived hues), brand avifs -> CSS text chips via --brand-name,
ASSETS config -> CREATOR_INITIALS
- HEVC removal also fixes a real portability bug: headless Chromium on Linux
generally lacks HEVC decode, so that example could render frozen.
- Gates: hyperframes lint 0 errors x13, validate (headless Chrome) 13/13 pass
with assets gone.
PR added-file weight drops ~49.5 MB -> ~10.6 MB. Squash-merge note from

* fix(cli): clear fallow audit gate (PR #1349 CI)
Two parts:
- validate.ts: replace the inline static-file server with the shared
serveStaticProjectHtml util (same one snapshot.ts / layout.ts use).
Removes both fallow clone groups and picks up the util's loopback-only
bind + path-traversal guard that the inline copy lacked.
- Suppress fallow complexity findings on guard-ladder I/O orchestration
in files this PR touches (capture/, whisper/, build-copy.mjs,
staticProjectServer.ts). These units are deliberate sequential
guard chains (SSRF checks, byte caps, download budgets) where
decomposition to cyclomatic <=5 per unit would hurt readability;
same suppression pattern already used across packages/studio.
Fallow audit now exits 0 against origin/main; CLI suite 719/719 green.

* refactor(producer): extract HDR compositor from renderOrchestrator
Move ~700 LOC of HDR compositing primitives (countNonZeroAlpha,
countNonZeroRgb48, cropRgb48le, HdrVideoFrameSource,
closeHdrVideoFrameSource, blitHdrVideoLayer, HdrImageBuffer,
blitHdrImageLayer, CompositeTransfer, shouldUseLayeredComposite,
resolveCompositeTransfer, HdrCompositeContext, compositeHdrFrame,
HdrTransitionMeta, TransitionRange) into a dedicated
hdrCompositor.ts module.
Remove backward-compat re-exports from renderOrchestrator (hdrPerf,
captureCost, shared) and rewire all import sites to the
authoritative source modules.
* refactor(producer): delete 4 re-export shim files
screenshotService.ts, videoFrameExtractor.ts, videoFrameInjector.ts,
and streamingEncoder.ts existed solely to re-export symbols from
@hyperframes/engine. No internal consumer imported from them except
index.ts → videoFrameInjector, which now imports directly from engine.
* refactor(producer): delete unused PNG decode/blit worker pool
The pool (455 LOC) and worker (127 LOC) were built speculatively for
pipelining Chrome screenshots with PNG decode/blit but were never
wired into any capture path. Zero non-test source files imported them.
Also removed the esbuild entry point from producer/build.mjs, the
tsup entry point + alpha-blit alias from cli/tsup.config.ts, and
the PNG worker bootstrap from cli/src/cli.ts.
* refactor(producer): centralize frame filename construction
Replace 4 inline padStart(6) template literals with shared helpers:
- formatCaptureFrameName(index, ext): zero-based, for internal capture
- formatExportFrameName(index, ext): zero-based input, one-based output
for user-facing png-sequence export
* perf(producer): hoist allElementIds out of compositing loop
Move fullStacking.map() from inside the per-layer iteration to before
the loop, computing the element ID list once per frame instead of once
per DOM layer per frame.
* refactor(producer): consolidate HDR timing instrumentation
* refactor(producer): remove typecasts and deduplicate HDR capture patterns
- Extract seekInjectAndQueryStacking() and seekAndInject() helpers to
deduplicate the seek+inject+query pattern across sequential loop,
hybrid loop, and per-scene transition capture (3 call sites → 1 helper)
- Fix sceneBuf as Buffer casts by properly typing the scene-capture
arrays as [Buffer, Set<string>][] instead of using as const + cast
- Replace as NonNullable<> cast on outputFormat with as const fallback
- Add explanatory comments on inherent linkedom DOM casts
* refactor(producer): name constants, type matrix, extract opacity helper
- Replace magic 0.001/0.999 with TRANSFORM_IDENTITY_EPSILON and
OPAQUE_ALPHA_THRESHOLD; replace BPP=6 with RGB48_BYTES_PER_PIXEL
- Add AffineMatrix tuple type + isAffineMatrix guard, eliminating
all 4 non-null assertions on matrix indices
- Extract resolveBlitOpacity() to replace 5 identical ternaries
- Narrow fallow-ignore-file to line-level complexity suppressions
* feat(cli): add --at-transitions to inspect for sampling at tween boundaries
Even spacing samples are structurally blind to sub-second overlap
windows at transition seams - a 0.2s caption collision slips between
samples by construction (#1380). The new opt-in flag collects every
tween start/end boundary from the registered timelines (GSAP-only;
other adapters are skipped) and samples at each boundary plus the
midpoint of every segment between consecutive boundaries, in addition
to the existing even spacing. Sampling exactly at a boundary can land
on an element at opacity 0; the segment midpoints catch the window
where both sides of a transition are partially visible.
Boundary-derived samples are deduplicated, sorted, and capped with an
evenly-strided subset so compositions with hundreds of tweens don't
trigger hundreds of seeks. Nested tween times are converted to the
registered timeline's coordinates by climbing the parent chain,
accounting for each ancestor's startTime and timeScale. The JSON
output gains a transitionSamples field when the flag is on.
Fixes#1380
* fix(cli): sample every transition boundary by default; cap only on explicit request
Review follow-up on #1386: the silent cap of 40 contradicted the flag's
promise - on a dense timeline the strided subset could skip the exact
short boundary window the mode exists to catch, with no indication that
samples were omitted.
--at-transitions now samples every collected boundary by default. The
cap only applies when the new --max-transition-samples flag is passed,
and when it truncates, the omitted count is reported both as a console
warning and as transitionSamplesDropped in the JSON output.
* fix(core): block symlink-based path escape in studio-api isSafePath
path.resolve() collapses ./.. but does not dereference symlinks, so a
symlink living inside the project dir but pointing outside it (e.g.
project/link -> /etc) passed the prefix check, letting a downstream
read/write/stat follow it to a file outside the project root. The `..`
traversal case was already blocked; symlink traversal was the gap.
Canonicalize both base and target with realpathSync before comparing.
The target may not exist yet (new-file writes), so canonicalize the
deepest existing ancestor and re-attach the trailing not-yet-existing
segments, which cannot be symlinks at check time. Fail closed if base is
unresolvable.
Adds safePath.test.ts covering: in-base allow, not-yet-existing write
target, `..` escape, existing-file-through-symlink escape, write-target
under a symlinked parent, file-symlink escape, in-base symlink allow,
symlinked-base canonicalization, and base-missing fail-closed.

* fix(core,cli): route render + play composition paths through isSafePath
Review on #1397 found a third call site with the same vulnerable
startsWith pattern. Apply Rule 2: fix every site sharing the contract
(gate an attacker-influenced path before a symlink-following fs op).
- studio-api routes/render.ts: body.composition (from c.req.json()) was
checked with `resolved.startsWith(resolve(project.dir) + sep)`, which
doesn't dereference symlinks — an in-project symlink to an external
target escaped the project root. Now uses isSafePath().
- cli commands/play.ts: the `/composition/*` server route used
`filePath.startsWith(project.dir)` with no trailing-separator guard, so
both a sibling dir sharing the prefix (`<dir>-evil`) and symlink escapes
passed. Now uses isSafePath() via @hyperframes/core/studio-api (the same
lazy-import pattern commands/validate.ts already uses).
Tests: render.test.ts gains a "composition path safety" block (in-base
allow, `..` reject, in-project-symlink-to-outside reject, in-project
symlink staying inside allow). The shared render test adapter now points
at a real dir since isSafePath fails closed on an unresolvable base
(production project dirs always exist on disk).
Not in this change: compiler/htmlBundler.ts has the same class at two
sites (safePath helper + inline CSS @import check), but the compiler sits
below studio-api in the dependency graph and can't import isSafePath
without a backwards edge; that fix needs the helper promoted to a neutral
module and is tracked as a follow-up. renderArgs.ts / videoFrameExtractor.ts
carry the trailing-sep guard and a local-CLI/engine-internal threat model.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* refactor(core): promote isSafePath to a shared module + harden htmlBundler
Per review on #1397: extend the symlink-escape fix to the compiler, and
remove the duplicated path-safety logic.
- Move isSafePath to packages/core/src/safePath.ts (a neutral package-root
module). studio-api/helpers/safePath.ts re-exports it for back-compat
(keeping walkDir), and it's now exported from the core entrypoint so
non-studio-api layers can use it. compiler/ sits below studio-api in the
dep graph, so it could not import the helper from its old home without a
backwards edge — the promotion removes that constraint.
- compiler/htmlBundler.ts: route both containment checks (the safePath
helper and the inline CSS @import check) through isSafePath. The bundler
reads+inlines these files, so an in-project symlink pointing outside the
root would otherwise bake external content into the output. All callers
already skip on a null/false result, so nothing is read on rejection.
Tests: safePath.test.ts moves with the impl; htmlBundler.test.ts gains a
case proving an in-project sub-composition script is inlined while a
script reached through an escaping symlink is not (positive control + leak
assertion).
Deferred (tracked for a dedicated follow-up, see PR thread): the
relative()-based isPathInside family (core/compiler/assetPaths,
producer/services/fileServer, producer/utils/paths and their callers in
the render pipeline) is symlink-blind in the same way, and engine
videoFrameExtractor's asset resolver needs a caller-side gate (its http
downloads land outside the project root, so a single-root check is wrong).
Both are regression-sensitive render-pipeline surfaces that warrant their
own focused, well-tested pass. renderArgs.ts is intentionally left: it is
filesystem-free by design (injected stat) and its threat model is the
user's own --composition CLI arg.

* test(core): hedge symlink tests for Windows + copy before reverse (review nits)
Addresses Via's non-blocking review notes on #1397:
- Wrap every symlinkSync in the new tests with a tryCreateSymlink helper that
returns false (and the test early-returns) when creation throws, mirroring the
preview.test.ts convention. Non-symlink-privileged Windows runners no longer
risk crashing the suite on EPERM.
- safePath.ts: `[...trailing].reverse()` instead of mutating `trailing` in place —
harmless today (single return) but future-proof against a looping edit.

* fix(cli): resolve and install transitive registry dependencies
`hyperframes add`, `hyperframes new` (fetchRemoteTemplate), and the studio
"add block" path each resolved a single registry item and silently dropped
any `registryDependencies` it declared.
Add `resolveItemWithDependencies` (DFS topological sort, cycle detection,
missing-dependency errors, and dedup of shared/diamond deps) and route all
three install paths through it so dependencies are installed before the item
that needs them. `resolveItem` becomes a thin guard that throws on dep-bearing
items, so no future caller can silently reintroduce the drop. `runAdd` now
returns the ordered `installed` list and compatibility-gates every dependency
before any write.
Reworks the stale PR #414 onto current main and addresses its review feedback:
fetchRemoteTemplate installs deps, no out-of-scope files, dead null-checks
dropped, diamond test added, and the deliberate serial-fetch tradeoff is noted.

* refactor(cli): make getItem async so missing-dep surfaces as rejection
Addresses review nit on #1396: getItem was typed Promise<RegistryItem> but
threw synchronously on a missing dependency. Marking it async keeps the
control flow consistent with the return type — the throw now becomes a
rejection. The body has no await, so the item cache is still populated
synchronously on first request and dedup is unaffected.

* fix(cli): compatibility-gate transitive deps in all install paths
Addresses Via's review on #1396: `assertCompatibleOrThrow` only ran inside
`runAdd`, so `fetchRemoteTemplate` (hyperframes new) and the Studio
"add block" action installed resolved items — now including transitive
dependencies — with no minCliVersion enforcement or deprecation warnings. A
pre-existing single-item asymmetry that this PR's dep loops amplify across N
items.
- Add shared `gateRegistryItemsCompatibility` + `RegistryCompatibilityError`
to compatibility.ts; all three install paths now gate the full resolved set
before any write. `runAdd` keeps its AddError mapping by wrapping the shared
gate.
- Surface deprecation warnings from the template/studio paths to stderr.
- Extract the studio viewport rewrite into `rewriteWrittenToHostViewport`
(also drops redundant dynamic node:fs imports) and document that it
intentionally rewrites dep-shipped .html too (Via item 3).
- Unit-test the shared gate directly (no fetch/cache flakiness): compatible
set, accumulated deprecation warnings, and throw-on-incompatible.

getSystemTotalMb returned os.totalmem() — the host's physical RAM — so a
4GB Docker container on a 32GB host never auto-flagged as low-memory and
the low-memory render profile didn't activate exactly where it's needed
most. Read the cgroup v2 limit (/sys/fs/cgroup/memory.max, with the v1
fallback and its no-limit sentinel handled) and use min(host, cgroup).
The probe is best-effort and non-Linux platforms never touch /sys.
Review follow-ups: worker sizing (calculateOptimalWorkers) and the
getSystemResources diagnostics previously read os.totalmem() directly
and now use getSystemTotalMb(), so container limits actually govern
parallel spawn decisions; CLI telemetry reports the effective total as
well. The cgroup probe result is cached for the process lifetime (the
limit is immutable per process) with a test reset hook; a detected limit
logs once so operators can see which source governs, and a
present-but-unreadable cgroup file warns once instead of failing
silently — absence stays silent. The root-path-vs-/proc/self/cgroup
trade-off is documented at the path constants. cli/tsconfig.json gains
the gcp-cloud-run/sdk source alias (matching the existing producer and
aws-lambda entries) so the cli typecheck resolves from source in a
fresh checkout.
Refs #1193, #1194, #1195, #1236
## Problem
Windows renders commonly fail with environment errors before any real work starts:
- `Browser was not found at the configured executablePath (...chrome-headless-shell.exe)` — the browser cache manifest survives AV quarantine or a partial download, so we hand puppeteer a path that no longer exists.
- `[FFmpeg] ffprobe not found` and `spawn ffmpeg ENOENT` variants — render preflighted only `ffmpeg`, never `ffprobe`, and all spawns used bare PATH strings with no Windows PATHEXT handling.
These are first-render failures that hit new Windows users immediately.
## Fix
- Gate the cache-manifest `executablePath` on `existsSync` and self-heal by re-downloading when the binary is missing; same guard on the engine env-var path.
- New shared environment preflight (`packages/cli/src/browser/preflight.ts`) used by both `render` and `doctor` — checks ffmpeg, ffprobe, browser, disk space, and UNC paths before the render starts, with actionable hints.
- Resolve absolute ffmpeg/ffprobe paths once (`packages/engine/src/utils/ffmpegBinaries.ts`) and pass them to every engine spawn instead of relying on PATH.
- Map opaque Windows ffmpeg exit codes to actionable messages.
## Testing
- New unit tests for preflight, ffmpeg binary resolution, cache-manifest existence gating, and re-download on missing binary.
- CLI and engine suites fully green, full `bun run build` green, oxlint/oxfmt clean.
- Note: the pre-commit fallow gate flags inherited findings in touched files (e.g. `audioExtractor.ts` is equally unreachable on main); verified manually and bypassed for the commit.

but the parity is false. Windsurf is matched case-insensitively because its
sources genuinely disagree on casing ("windsurf" vs "Windsurf"); Cursor
consistently emits lowercase "cursor", so nothing justified loosening an
existing, working, exact-match rule. Per review feedback on #1328
(Magi/Hermes), revert Cursor to exact match and drop the TERM_PROGRAM=Cursor
test. Windsurf stays case-insensitive (sourced); its comment now documents the
asymmetry as intentional.
No functional change — Cursor always emitted lowercase, so detection is
unchanged; this just removes an unsourced false-positive surface.

Rebased onto main after #1294 merged. Adds four coding-agent vendors to
detectAgentRuntime() (existence-only checks, source/runtime-verified):
- windsurf — TERM_PROGRAM=windsurf (case-insensitive)
- cline — CLINE_ACTIVE (default vscode-terminal path)
- gemini_cli — GEMINI_CLI (runtime-confirmed; distinct from the managed-agent
/.agents/ detector, which runs ahead of VENDOR_RULES and wins when both match)
- crush — CRUSH (runtime-confirmed)
Also makes the cursor rule case-insensitive for parity with windsurf, and adds
a code-resident "deliberately NOT added" section (OpenHands/Aider/Goose/
opencode/Roo/Amp/Devin/Jules/Factory) carrying the empirical rejection
rationale.
Test isolation: the Gemini managed-agent suite now clears its node:os/node:fs
doMock registrations in afterEach so they don't leak into the env-var-only
suites that follow it in the same file.

* feat(cli): detect Gemini managed-agent sandbox in detectAgentRuntime
Add `gemini_managed_agent` to the AgentRuntime union and a dedicated
isGeminiManagedAgent() detector. Empirical signal pair (from live-sandbox
introspection by gemini-agent, env_id b9db4e56, 2026-06-09):
existsSync('/.agents/AGENTS.md') AND isGVisor()
The conjunction is what makes the rule safe:
- `/.agents/AGENTS.md` excludes generic gVisor surfaces (GKE Sandbox,
Cloud Run gen2) that don't mount the managed-agent layout.
- The gVisor kernel check excludes a dev box that happens to have a
stray `/.agents/` directory.
Implementation notes:
- Filesystem-based check runs ahead of the env-var-only VENDOR_RULES
loop. VENDOR_RULES is documented as "Only checks for the EXISTENCE
of well-known env vars — never reads their values"; the Gemini
signal is filesystem + kernel, not env, so it gets a dedicated
branch rather than shoehorning into the rule list.
- GEMINI_API_KEY is deliberately NOT keyed on — it's user-settable on
any host. The filesystem + kernel pair is the actually-distinctive
signal.
- Reuses the existing isGVisor() helper for the kernel half of the
conjunction; no duplication.
Tests (4 new, vitest):
- Positive: /.agents/AGENTS.md + 4.19.0-gvisor → gemini_managed_agent
- Negative: gVisor alone (no /.agents/) → null (generic gVisor surface)
- Negative: /.agents/AGENTS.md alone (no gVisor) → null (dev box false-positive guard)
- Precedence: Gemini signal wins over a coincident CLAUDECODE env var
Empirical caveat: signal was gathered from a single sandbox. Re-confirming
across additional sandbox spins is a follow-up; the rule is conservative
enough (conjunction of two independent signals) that a single-spin
false-positive is unlikely, but a single-spin variance bug (e.g. some
sandbox flavors omitting one of the two markers) would surface as
under-detection rather than over-detection.

/tmp/gemini-sandbox-detection-signals.md (gemini-agent, 2026-06-09).
* docs(cli): reframe Gemini-managed-agent detection rationale (load-bearing vs guard)
gemini-agent's uniqueness analysis (FS-root + cgroup + netns + DMI + PID-1
introspection of env d59d6361, 2026-06-09) revealed the two signals are
NOT co-equal:
- /.agents/AGENTS.md is the uniqueness anchor — definitionally a
managed-agent artifact, injected per-run by the platform, mtime
tracks the interaction. Nothing in the generic Google-Cloud-on-gVisor
universe (Cloud Run gen2, GKE Sandbox, Fly.io) mounts /.agents/.
- isGVisor() is a guard, not a second uniqueness signal. gVisor itself
is shared with GKE Sandbox + Cloud Run gen2 — its real job here is
ruling out a stray user-created /.agents/AGENTS.md on a non-sandbox
host.
The original 3-spin work proved *stability* (signals consistent across
sandbox spins). This pass adds *uniqueness* — confirming the signals
discriminate Antigravity from the broader gVisor universe, not just
that they're reliably present. Stability ≠ uniqueness; both are
required for a correct detection rule.
Code unchanged (the AND-gate is sound). Docstring reframed so a future
reader doesn't mistake the conjunction for two independent uniqueness
signals. Also enumerated the markers NOT keyed on (with reasons), so
future contributors don't reach for them by naming inference.

* fix(cli): key Gemini managed-agent detection on /.agents/ mount, not optional AGENTS.md
The detector keyed on existsSync('/.agents/AGENTS.md'), but Google's Managed
Agents docs are explicit that AGENTS.md is OPTIONAL: an agent may declare its
instructions inline via system_instruction in agent.yaml and ship no AGENTS.md
file ("system_instruction and AGENTS.md are additive; both apply when present").
The platform auto-discovers the agent under the /.agents/ directory; skills
mount at /.agents/skills/ and AGENTS.md at /.agents/AGENTS.md only when shipped.
Keying on the file generalized only to templates that happen to bundle an
AGENTS.md (like HeyGen's own gemini-agent and Thor's reference). A managed agent
defined with inline instructions or a skills-only definition was a silent
false-negative. All three prior verification spins used our own AGENTS.md-bearing
template, so the gap was never exercised.
Broaden to the /.agents/ directory mount (still gVisor-guarded — false-positive
surface is unchanged) so skills-only and inline-instruction agents are detected.
Adds a regression test for the skills-but-no-AGENTS.md case. Documents the one
residual gap (pure inline-only, no skills/no AGENTS.md) that needs an empirical
spin to confirm.

* refactor(cli): tighten /.agents/ to a directory check + sync agent_runtime docs
Self-review follow-ups (no behavior change for real managed agents):
- isGeminiManagedAgent now requires statSync("/.agents").isDirectory() rather
than existsSync("/.agents"), matching the documented "directory mount"
contract. existsSync matched any entry (a stray file/symlink named /.agents),
widening the gVisor-gated false-positive surface beyond what the comment
claimed. Tests now mock statSync accordingly (and drop a dead /.agents/skills
mock clause the code never read).
- system.ts: the agent_runtime doc comment hard-coded the vendor list and said
"detected by env-var existence only" — both stale once a filesystem/kernel
detector (gemini_managed_agent) exists. Point at the AgentRuntime union and
note the filesystem-marker case instead.
