* fix(producer): credit held video tails in coverage gate
* test(producer): decouple makeExtracted's durationSeconds default from delivered frame count
Defaulting durationSeconds to delivered/fps made any test modeling a
delivery shortfall silently report full coverage unless it remembered
to override durationSeconds afterward. Default to Infinity instead so
callers fall into the 'no usable source duration' branch (full slot
required) unless they explicitly pass a duration.
* fix(core): stop the async media-metadata rebind once render capture starts seeking
scheduleMetadataDurationHydration re-resolves and can swap the captured
GSAP timeline off a debounced loadedmetadata/durationchange event, fully
uncoordinated with the producer's own per-frame renderSeek calls. When a
full-length <video>'s metadata resolves after capture has already begun
(slow I/O, Docker), this races the deterministic BeginFrame capture loop
and can reflow sub-composition state mid-render, producing phase-offset
duplicate content in captured frames (#2550).
Render-mode duration correction already happens deterministically during
the probe stage before capture starts, so once renderSeek has been called
once there is nothing left for this self-correction to do — gate it off
for the rest of the session.
* fix(core): scope the metadata-rebind guard to actual render/export pages
renderSeek isn't capture-exclusive — Studio's own preview iframe falls
back to it for compositions whose timeline overhangs every native
adapter's duration. Gating the HF#2550 fix on renderCaptureSeekStarted
alone silently disabled the metadata-driven duration self-correction for
that live-scrub case too, where it's still needed. Require the render/
export page signal (window.__HF_EXPORT_RENDER_SEEK_CONFIG, set only by
the producer's fileServer.ts) alongside it, and add a regression test
covering the Studio-preview case.
* fix(engine): stop requesting beyond-viewport capture for video comps that don't need it
Root-caused HF#2550 by reproducing the reporter's public repro end-to-end
(not just the timeline-rebind mechanism from the earlier commits in this
branch) on native Linux: instrumented the actual DOM state during a real
capture session and confirmed the sub-composition never double-mounts —
getBoundingClientRect and the timeline's own local time both match the
single, correct DOM tree throughout. The phantom second copy only exists
in the captured screenshot pixels.
Bisected it to captureBeyondViewport: resolveVideoCaptureBeyondViewport
(#1094's tall-portrait fix) forces `Page.captureScreenshot`'s beyond-viewport
path on for any render with a native <video>, regardless of whether the
page's content actually overflows the declared capture height. On
SwiftShader that beyond-viewport path can composite a stale, vertically
offset paint of the page alongside the fresh one for content that fits
entirely within the viewport — producing exactly the reported phase-offset
duplicate. Disabling captureBeyondViewport (repro's video still present)
eliminates the duplicate outright; re-enabling it reproduces the duplicate
byte-for-byte, isolating it as the actual cause.
Adds pageContentExceedsCaptureHeight, a ground-truth measurement of the
page's actual scrollHeight against the requested capture height, and wires
it into initializeSession to downgrade captureBeyondViewport back to false
once the page is settled and it's confirmed unnecessary — the "reliable
clip predictor" the original #1094 fix's ponytail comment flagged as
missing. This keeps #1094's fix intact for content that genuinely
overflows while closing the SwiftShader ghosting hazard for the (common)
case of video that fits inside its own viewport.
* test(producer): add HF#2550 video+sub-composition regression fixture
Checks in the reporter's confirmed real-world reproduction (media
regenerated via ffmpeg testsrc2, matching their public repro repo) as a
regression fixture, with a golden baseline rendered against the fix.
Verified end-to-end via the project's own Docker regression harness:
- Rendering this fixture with the fix produces the golden baseline
(clean, single flowchart instance, captureBeyondViewport correctly
downgraded).
- Direct CLI renders (not through this harness) against unpatched code
reproduce the reported phantom-duplicate artifact reliably (10/10).
Caveat documented in meta.json: the underlying bug is timing-dependent.
Two harness runs against unpatched code, using this same fixture, did
not reproduce the artifact (0/2) — the harness's in-process render path
apparently doesn't hit the same race window a direct CLI process does on
this host. This fixture is a best-effort regression guard and a
preserved real-world repro, not the sole protection — the deterministic
guard is packages/engine/src/services/screenshotService.test.ts's
pageContentExceedsCaptureHeight unit tests, which exercise the actual
fix logic directly.
Also adds an .gitattributes LFS rule for this fixture's source
index.html (744 KB — carries the real project's embedded base64
assets, over the largefiles hook's 500 KB non-LFS limit).
* fix: route HF#2550 fixture binaries through LFS (were committed raw)
filter.lfs.clean/smudge were locally configured as a no-op "cat" in
this repo's shared .git/config, silently disabling LFS filtering for
every worktree. The previous commit's large binaries (output.mp4,
compiled.html, source index.html, source video) landed as raw blobs
instead of LFS pointers as a result. Ran `git lfs install --local
--force` to restore the correct filter commands, then re-staged the
affected files so they commit as proper LFS pointers.
* fix(engine): address capture viewport review feedback
The prior fix (dc410ca) dropped `pathToFileURL` from the pad-concat step
to make FFmpeg 8.x on Windows stop rejecting `file:///C:/…` URLs — but
kept feeding the concat script via `pipe:0` stdin. That combination
broke Linux CI: FFmpeg's concat demuxer resolves bare paths in the
script against the base URL of the script's own source, and when the
script is fed via `pipe:0` the base URL is `pipe:`. Absolute POSIX
paths (`/tmp/foo.aac`) then join to `pipe:/tmp/foo.aac`, which the
demuxer tries to open as a pipe and fails with:
[concat @ 0x…] Impossible to open 'pipe:/tmp/…/audio.aac'
pipe:0: End of file
Manually reproduced with `ffmpeg-static@7.0.2` on this repo's binary.
Fix: write the concat script to a real temp file (`<outputPath>.concat-
list.txt`) and pass `-i concatListPath` — matching the sibling concat
in `distributed/assemble.ts:180-186` exactly. A real file's directory
becomes the base URL, so absolute paths in the script resolve as-is on
both Linux and Windows. The `file://` scheme prefix stays out of the
script (Windows FFmpeg 8.x fix preserved) and no `pipe:` prefix gets
prepended (Linux regression fixed). Cleanup path list now covers both
the silence tail and the concat list script.
Also drops the now-unused `runFfmpegWithStdin` helper — no consumer
needs stdin plumbing anymore.
Regression pins in `audioPadTrim.test.ts`:
- `does not emit file:// URLs …` — Windows arg-shape pin (unchanged
intent, moved from `stdin` to `concatListContent` field).
- `materializes the pad-concat script to a real file …` — new pin
that asserts `-i` is not `pipe:0` and points at the concat list
path, so the Linux failure mode can't regress.
CI failures fixed:
- CI / Producer: integration tests (assemble.test.ts pad case)
- regression / regression-shards shard-1 (style-3-prod field-signal
end-to-end render exercising the assemble pad path)

Three findings, all resolved:
- packages/producer/src/server.ts `render` (CRAP 31.6, cyclo 10 — minor):
pre-existing complexity; the PR only threads
`outputResolutionAspectAgnostic` through parseRenderOverrides /
RenderInput and does not touch `render`. Line-shift fingerprint —
exempted via health.ignore with justification comment.
- packages/producer/src/services/distributed/plan.ts `plan` (CRAP 36.7,
cyclo 33 — major): pre-existing complexity; the PR only adds one
optional field spread inside `plan` and does not add branches.
Line-shift fingerprint — exempted via health.ignore with justification.
- packages/producer/src/services/render/stages/compileStage.ts
`runCompileStage` (cyclo 23, cognitive 19 — minor): this one is a
real complexity bump from the two-branch aspect-agnostic re-target
block added in the fix. Extracted the block into a local helper
`adaptAspectAgnosticResolution` so `runCompileStage` stays under both
the cyclomatic (20) and cognitive (15) thresholds.
Verified locally with `fallow audit --base origin/main --fail-on-issues`
(exit 0, "No GitHub PR/MR findings") and `tsc --noEmit` on the producer
package.

The aspect-agnostic resolution aliases (`--resolution 1080p` / `hd` / `4k` / `uhd`) previously all normalized to a landscape preset, which rejected portrait 1080x1920 compositions with 'Output resolution incompatible'. Users had to specify the orientation-bearing alias (`1080p-portrait`) or render at native.
This threads two new fields (`outputResolutionAspectAgnostic` + `outputResolutionRaw`) through the render pipeline. At the CLI layer we detect whether the user's flag was an aspect-agnostic alias; at the compile stage we re-map the preset to the composition's orientation via the existing `suggestMatchingPreset` sibling-lookup (formerly private). Explicit orientation-bearing aliases and canonical presets stay strict.

The `audioPadTrim` module's pad-concat step generates a concat script
whose file directives use `file://` URLs (built via Node's
`pathToFileURL`). FFmpeg 8.x on Windows rejects these with
"Impossible to open file:///C:/…" — its `file:` protocol handler strips
the scheme leaving `///C:/…`, which Windows path parsing then rejects.
Field-signal (4 reports over ~24h, all win32/x64, CLI 0.7.59):
- ts=1784169914 (Baoyu, 60s render, native audio assembly failed)
- ts=1784177061 (andre 22cores, 345.87s composition, 9 WAV audio elements)

-t 16 -c:a aac out.aac` works with the same binary, so the tool's
audioPadTrim invocation is the incompatible part)
- ts=1784177375 (duplicate reporter follow-up)
The concat approach itself is fine — the sibling concat scripts in
`assemble.ts` and `chunkEncoder.ts` pass raw paths (no `pathToFileURL`)
and work on Windows. `audioPadTrim.ts` was the outlier introduced in
PR #1615 (2026-06-20). Aligns with the codebase convention.
Regression pin: unit test asserts the pad-concat stdin never contains
the `file://` scheme, including for a Windows-shaped input path.
End-to-end verification requires a Windows + FFmpeg 8.x reviewer; the
unit test snapshots the arg shape.

Follow-up on Miga's review of #2512. The regression fixture
`escape-hatch-fatal-fallback` is tagged `field-signal-reproducer` and
`known-broken` so it's skipped from the default sweep via
`--exclude-tags transparency,field-signal-reproducer` in the
`test:regression*` scripts in packages/producer/package.json. But
`Dockerfile.test`'s ENTRYPOINT invoked the harness directly (`bunx tsx
src/regression-harness.ts -- --sequential`), bypassing those scripts —
so `bun run docker:test*` and the aws-lambda smoke tests would still
try to run the known-broken fixture and fail. CI's own regression sweep
was insulated only because it hardcodes per-shard positional test names
that don't include this fixture, but that's incidental, not by design.
Bake the exclude-tags into the Dockerfile.test ENTRYPOINT itself so
every user of the image (local `docker:test*`, aws-lambda smoke, any
adopter running the reference image) picks up the same skip contract.
Docker CMD args appended after the entrypoint (e.g. matrix shard
positional test names in .github/workflows/regression.yml, or
`--mode=distributed-simulated`) still parse correctly — the harness
applies excludeTags after testNames-filtering (see discoverTestSuites
in regression-harness.ts).
Also exports `parseArgs()` from regression-harness.ts and adds
regression-harness-parse.test.ts to pin the `--exclude-tags` comma-parse
contract, so any future change to the parser or the values baked into
the Dockerfile / package.json will trip a red test rather than silently
diverging.
Verification A (harness comma-parses `--exclude-tags transparency,
field-signal-reproducer`) already worked pre-fix; the new test file
codifies it. Verification B (Docker ENTRYPOINT propagates the same
skip) is what this commit fixes.

validated against the same shape the field reported.
Skip mechanism (belt-and-suspenders):
1. meta.json tagged `field-signal-reproducer` and `known-broken`;
producer/package.json test:regression* scripts add the tag to
--exclude-tags alongside the existing `transparency` skip.
2. Not registered in any .github/workflows/regression.yml shard's
args, so the CI regression sweep won't pick it up either.
Un-skip when a fix lands: drop the tags from meta.json AND add the
fixture id to a shard's args in the workflow. See src/README.md for

page.goto hit Navigation timeout of 60000ms twice on a CSS 3D + audio
composition; Docker rendered the same composition successfully.
Puppeteer's stock "Navigation timeout of 60000 ms exceeded" text names
none of HyperFrames' existing escape hatches, so the reporter had no
signal that the failure had knobs.
Wraps main-render Puppeteer `page.goto` errors matching
/Navigation timeout|net::ERR_TIMED_OUT/i with an augmented message that
names:
- The effective timeout currently applied (`cfg.pageNavigationTimeout`).
- Raise-the-timeout: `PRODUCER_PAGE_NAVIGATION_TIMEOUT_MS` env,
`--browser-timeout` CLI flag (seconds).
- Browser-binary escape hatch: `HYPERFRAMES_BROWSER_PATH` env.
- Field-signal shape: darwin/arm64 + CSS 3D + audio compound Docker
hint — gated on all three inputs being explicitly true; falls back
to generic hints when any input is unknown.
Mirrors #2443's HYPERFRAMES_BROWSER_PATH surfacing pattern (which
covered download-time failures) at the runtime `page.goto` layer.
Non-matching errors flow through unchanged. Original error preserved
via `err.cause`.
Wired into `renderOrchestrator.executeRenderJob`'s top-level catch,
composed after `augmentProtocolTimeoutError` so the two augmenters
never both fire on the same error (mutually exclusive regexes).
Current wire-up passes no `hasCss3D` / `hasAudio` context — no
compile-time CSS-3D signal is threaded through the render pipeline,
and `hasAudio` is block-scoped inside the try. Per the helper's
fallback docs, unknown flags route to the generic env + browser-path
hints. A future compile-time CSS-3D scan can thread both flags to
enable the full compound Docker hint without touching this helper's
signature.
