Address @vanceingalls and @miguel-heygen review findings on #852:
1. Asymmetric soft-skip — only the N=1 plan+render+assemble call was
wrapped in the host-Chrome-failure catch; an SwiftShader / cold-Chrome
flake on the N=4 call would hard-fail instead of soft-skip. Factor a
local runRender() helper and wrap both calls.
2. Vacuously-passing length assertion — 'expect(framesOne.length).toBe(
framesFour.length)' passes when both runs produce 0 frames. Pin the
absolute count (EXPECTED_FRAME_COUNT = 60) so a regression that
identically truncates both renders shows red.
3. CDN version drift — anime-boundary loaded gsap@3.14.2 from jsdelivr
while every other boundary fixture loaded 3.12.2 from cdnjs. Unify on
cdnjs@3.12.2 so the next reader doesn't have to wonder why one fixture
diverges. (gsap is an empty duration-driver in all six fixtures so
the version was never load-bearing — but the divergence reads as
intentional and isn't.)
4. VIDEO_EXT type narrowing — the lookup is Record<"mp4"|"mov"|"webm">
but outputFormat includes "png-sequence". The isPngSequence ternary
short-circuits before png-sequence can reach the indexing site, but TS
can't narrow through that. Add an explicit cast at the indexing site
(not the lookup definition — over-widening to include "png-sequence":
undefined would defeat the existence guarantee).

Address findings from a three-agent code-review pass over the Phase 4 stack:
- regression-harness: hoist `readdirSync` out of the per-checkpoint
failure-extraction loop (was running 20 redundant syscalls on every
failing png-sequence test). Drop redundant `existsSync` guards before
`mkdirSync(recursive: true)` and `rmSync(force: true)`. Replace the
three-deep ternary that built the output filename suffix with a
single `Record<format, ext>` lookup.
- regression-harness-distributed: flatten the `format === "mp4" ? {...} : {...}`
branching in the `plan()` call into a single config object with a
conditional spread. `plan()` already accepts `codec: undefined` for
non-mp4 formats, so the duplicate object was unnecessary.
- chunkBoundary.test: rename the stale "byte-identical mp4" test title
to "byte-identical frames" (the test now uses png-sequence). Trim the
10-line comment justifying `rejectOnSystemFonts: false` to the
essential WHY.
- renderChunk / plan.test / regression-harness: drop trailing-edge
comment phrases that pinned the prose to the PR's calendar context
("today", "v1.5", "pre-codec-knob output", section-numbered cross-
references to the planning doc).

1. validateMetadata's codec/format check read 'rc.codec !== undefined &&
rc.format !== undefined && rc.format !== "mp4"'. The behavior was
correct (omitted format defaults to mp4 downstream so codec is legal)
but relied on the reader knowing that default. Normalize 'effectiveFormat
= rc.format ?? "mp4"' before the comparison so the intent reads
directly.
2. The mp4-h264-sdr sibling carries inline rationale for the no-audio
choice (AAC frame quantization extends container.duration past
nb_frames/fps and trips the harness PSNR sampler) and the chunk-seam
mapping (crossfade window 0.9-1.1s straddles frame 30). mp4-h265-sdr

Two surgical changes, both isolated to the catalog-previews flow:
1. `packages/studio/src/player/hooks/usePlaybackKeyboard.test.ts`
PR #842 changed `seek()` to take `(time, { keepPlaying: true })` for the
A/E shortcuts. The keyboard-layout tests added by #839 still asserted the
single-arg form. Both landed on main without cross-checking, so `main`
itself has been failing Test/Windows since. Update the two assertions
to match the new signature. Same fix Miguel already authored on
`feat/studio-preview-pasteboard-bg`.
2. `registry/components/vignette/demo.html`
The original demo captured a frame where the vignette was at its
weakest point — the effect was nearly invisible in the static preview
used by docs. Reworked the demo so:
- The backdrop is a layered "cinematic still" (warm key + teal rim +
dark falloff) and includes a centered subject ("moon"), so the
vignette has a focal point to frame.
- Vignette starts soft (size 70%, alpha 0.35) and ramps to a dramatic
cinematic vignette (size 26%, alpha 0.92) over 1.6s.
- Peak intensity holds across t≈3.0s, which is exactly where the
catalog script samples the thumbnail (`Math.min(3.0, duration*0.6)`
with duration=5).
- Breathing motion in t=3.4–5.2s gives the video loop visible life
without disturbing the still frame.
`scripts/generate-catalog-previews.ts` still called `createCaptureSession`
with `fps: 30` and `createRenderJob` with `fps: 24`. Since commit 5dcc89c9
("feat(cli): accept ffmpeg-style rational fps") `CaptureOptions.fps` and
`RenderConfig.fps` are `Fps = { num, den }` rationals — a plain number
yields `options.fps.den === undefined` and:
```ts
beginFrameIntervalMs: (1000 * options.fps.den) / Math.max(1, options.fps.num),
// = (1000 * undefined) / Math.max(1, undefined) = NaN / NaN = NaN
```
After warmup, `session.beginFrameTimeTicks = (baseTickCount + 10) * NaN = NaN`,
and the next `HeadlessExperimental.beginFrame` CDP call fails with:
```
Protocol error (HeadlessExperimental.beginFrame): Invalid parameters
Failed to deserialize params.frameTimeTicks - BINDINGS: double value expected
```
This regression didn't surface earlier because the Catalog Previews workflow
only re-renders items whose files changed in the PR, so existing components
were never exercised against the new fps contract. The vignette addition is
the first new item since the refactor.
Fix: pass `{ num: 30, den: 1 }` and `{ num: 24, den: 1 }`.
Miguel (approved) and Vai (commented) both flagged the same
PSNR-threshold doc/code mismatch; Vai additionally flagged a
path-anchoring bug in the projectDir-copy filter and a dishonest type
cast. Addressed all five findings:
PSNR threshold doc/code mismatch (important):
- Module docstring, `resolveMinPsnrForMode` JSDoc, and tests/README.md all
claimed distributed-simulated tightens to ≥50 dB. The actual code uses
`max(fixture.minPsnr, 10)` — 10 dB is a pathology floor, the per-test
gate is the fixture's authored `minPsnr`. Updated all three doc sites
to describe what the code does. The 50 dB target in §5.1 is a per-
render distributed-vs-in-process contract; against the frozen baseline
it's unreachable for either mode (shared encoder/JPEG jitter), so it
can't be a per-fixture gate.
`PLAN_PROJECT_DIR_COPY_SKIP` regex matched absolute paths (important):
- `cpSync` calls the filter with the absolute source path, so a
`projectDir` whose absolute path happens to contain a blocklisted
segment (`/home/user/work/output/comp/`, `~/projects/dist/foo/`, etc.)
caused the filter to return false for every descendant — empty
compiled directory, broken render. Now matches relative-to-projectDir
segments via `path.relative()` + `split(sep)`. Switched from a regex
to a Set for clarity. Harness fixtures don't hit this because they
live under `tests/<name>/src/`, but adapters call `plan()` with
caller-supplied paths.
Dishonest type cast in regression-harness.ts (important):
- `as "mp4" | "mov" | "png-sequence"` claimed reachability for formats
that `validateMetadata` doesn't accept (the schema is `"mp4" | "webm"`,
and webm is rejected by `checkDistributedSupport`). Narrowed to
hardcoded `format: "mp4"` with a comment naming the metadata-schema
invariant that lets us do that.
Renamed `chunkVideoInjectorFactory` (nit):
- The variable was invoked once and never used again — "factory" implied
repeated calls. Inlined as a plain `videoInjector: BeforeCaptureHook | null`
ternary.
Replaced tautology test (nit):
- `expect(DISTRIBUTED_SIMULATED_MIN_PSNR_DB).toBe(10)` was a value-pin
over an exported constant. The invariant the JSDoc actually asserts is
"10 dB is below any real fixture's authored minPsnr"; if someone lands
a permissive fixture (minPsnr: 5), the value-pin doesn't catch it.
Replaced with a test that walks `tests/*/meta.json` and asserts every
authored `minPsnr` is ≥ the floor.
Validated in `docker:test --mode=distributed-simulated`:
font-variant-numeric, many-cuts, gsap-letters-render-compat,
style-1-prod, sub-composition-video — all PASSED.

Code reuse:
- Move `PlanVideosJson` interface + `meta/videos.json` path constant into
`services/distributed/shared.ts`; plan.ts and renderChunk.ts import from
there instead of redeclaring the same shape with the "duplicated here so
renderChunk doesn't import from plan.ts" comment.
- Replace hand-rolled `framePattern.slice(lastIndexOf("."))` with
`extname()` from `node:path` in `rebuildExtractedFramesFromPlanDir`.
Efficiency:
- Hoist `rebuildExtractedFramesFromPlanDir` + `createFrameLookupTable` +
`createVideoFrameInjector` out of the per-chunk closure in renderChunk.
Computed once per chunk now, not once per `createRenderVideoFrameInjector`
callsite (which `runCaptureStage` may invoke multiple times).
- Add a regex filter to `cpSync(projectDir → planDir/compiled/)` so
`node_modules`, `.git`, `output/`, `failures/`, `dist/`, etc. are not
copied. Real projects can have hundreds of MB in those directories;
shipping them to S3/Lambda /tmp on every render bloats cost and time.
- Drop redundant `if (!existsSync(metaDir)) mkdirSync(metaDir, {recursive:true})`
guards; `mkdirSync({recursive:true})` is already idempotent.
Quality:
- Strip narrative comments that told the story of debugging:
- renderChunk's 30-line "Two failure modes made the call actively
harmful" block → 4-line invariant on why `discardWarmupCapture` is
omitted.
- plan.ts's "DO NOT call cleanup()" block → 3 lines naming the
invariant.
- plan.ts's pre-seed-projectDir block → 7 lines on the file-server
invariant.
- renderChunk.ts top docstring's discardWarmupCapture paragraph.
- regression-harness-distributed.ts's PSNR-drift table (belongs in
DISTRIBUTED-RENDERING-PLAN.md, not the source).
- test file's docstring about which tests live where.
- Drop the unreachable IIFE-throw on `format === "webm"` in the harness
(the support check above rejected webm); replace with a plain
`as` cast.
- Replace dynamic `await import("node:fs")` with a top-level import in
`regression-harness-distributed.ts`.

The chunk worker passed `createRenderVideoFrameInjector: () => null` to
`runCaptureStage`, leaving the page's `<video>` elements to decode the
source mp4 against the virtual clock. Chrome's native video pipeline
seeks ±1 frame off what the in-process renderer captures (which uses
pre-extracted frames injected as images via createVideoFrameInjector).
That ±1 frame drift produced the PSNR gap on sub-composition-video and
style-1-prod against the in-process baselines.
Two pieces:
1. `plan()` now persists the engine's `VideoElement[]` (composition.videos)
and a serialized form of `extractionResult.extracted` (videoId,
srcPath, framePattern, fps, totalFrames, metadata — paths omitted) to
`<planDir>/meta/videos.json`. This is the data renderChunk needs to
reconstruct a `FrameLookupTable` without re-running the extract stage.
2. `plan()` no longer calls `frameLookup.cleanup()` after extraction.
That cleanup was rm-rf-ing each video's outputDir, which for the
in-process orchestrator is a scratch tree the renderer owns — but for
plan() that "scratch" IS `compiledDir/__hyperframes_video_frames/<videoId>/`,
the source material that the subsequent rename moves into
`planDir/video-frames/`. Cleaning it up before the rename left
planDir/video-frames/ with only the `_downloads/` subdirectory and no
actual frame files. Both `style-1-prod` and `sub-composition-video`
reproduced this on every distributed-simulated run; both pass after
the cleanup is dropped.
3. `renderChunk` reads `meta/videos.json`, rebuilds `ExtractedFrames[]`
by re-listing `planDir/video-frames/<videoId>/` for each video, calls
`createFrameLookupTable(videos, extracted)`, and wraps the result in
`createVideoFrameInjector` — the same hook the in-process renderer
uses. The rebuilt entries set `ownedByLookup: false` so any later
cleanup() call from the engine doesn't rm the planDir bytes another
worker may still be reading.

Validating the harness against a multi-chunk render (chunkSize=50 on
many-cuts, N=4 chunks) revealed that the previous "discard at startFrame-1
for chunk N>0" fix had a second deadlock mode: the discard's
frameTimeTicks (base + 49*interval) ended up LARGER than the captureStage
first-call's frameTimeTicks (base + 0). Chrome's compositor wedges when
asked to go backward in time as predictably as it wedges on a same-time
duplicate.
Both attempted fixes were trying to work around a problem that doesn't
exist: lastFrameCache is only consulted when Chrome returns
hasDamage=false, and every chunk frame seeks fresh DOM via __hf.seek()
before the screenshot, so hasDamage is always true and the cache is
never read. The priming step is unnecessary.

Add `* text=auto eol=lf` so text files are checked in with LF regardless
of the contributor's OS. Without this, Windows editors can save files
with CRLF (and sometimes a UTF-8 BOM), which makes every line differ at
the byte level on diff and trips GitHub's "Binary file not shown"
heuristic — see #840 for an example where a ~30-line change was
unreviewable for this reason.
Existing LFS rules already carry `-text` and remain unaffected.

Empirical investigation of --mode=distributed-simulated against many-cuts
revealed that the BeginFrame "hang" attributed earlier to a Chrome 148
SwiftShader compositor wedge was actually a renderChunk bug:
discardWarmupCapture was called with frameIndex=slice.startFrame, then
captureStage immediately captured frame 0 (relative) of the chunk's range.
For chunk 0 (slice.startFrame=0) these two calls produced the same
frameTimeTicks. Chrome's HeadlessExperimental.beginFrame deadlocks when
called twice in a row with the same frameTimeTicks — the compositor has no
new damage to advance for, and the second call hangs until the Puppeteer
protocolTimeout fires.
Tracing the chunk worker confirmed:
warmup call 1 t=0 -> ok
warmup call 60 t=1947 -> ok (loop exited)
beginFrame call #1 t=2333.33 -> returned, hasData=true, hasDamage=true
beginFrame call #2 t=2333.33 -> HANG
Fix: discardWarmupCapture skips chunk 0 (no prior frame to prime, and the
in-process renderer also has an empty cache at frame 0) and uses
slice.startFrame - 1 for chunk N>0 (the actual previous absolute frame,
which more accurately matches what the in-process renderer's cache holds
at the start of frame N).
The engine probe complications I added earlier — multi-step screenshot
test, inline data:URL pre-navigation, rastered-bytes assertion — were
chasing a phantom and are reverted to the original simple form.
chrome-headless-shell @stable on Linux with --use-angle=swiftshader
renders BeginFrame screenshots correctly after the warmup loop; what
looked like "wedged compositor" was the same frameTimeTicks deadlock
masquerading as a Chrome regression.
Also lowers the harness's distributed-simulated PSNR floor from 45 dB to
10 dB and switches to using the fixture's own minPsnr for both modes. The
45 dB floor was set against font-variant-numeric's static-content
baseline drift (~48 dB), but dynamic compositions like many-cuts produce
34-44 dB baseline drift even in-process — both renderers share the same
encoder/JPEG jitter floor, so requiring distributed to clear a tighter
threshold than in-process catches no real regression. 10 dB remains as an
absolute-pathology guard for fixtures with a permissive authored
threshold.
Validated end-to-end in `docker:test --mode=distributed-simulated`:
font-variant-numeric: PASSED (PSNR ~48 dB, audio correlation 1.000)
many-cuts: PASSED (PSNR 37-44 dB across rapid transitions)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three Phase 3 regressions surfaced when validating --mode=distributed-simulated:
engine: probeBeginFrameSupport approved chrome-headless-shell 148 even when
its SwiftShader compositor was wedged. The existing noDisplayUpdates:true
probe returns instantly on 148 and the screenshot variant returned empty
data without erroring. The real capture loop then hung on first frame with
"HeadlessExperimental.beginFrame timed out". Probe now navigates to a small
inline page (matching the real capture's compositor state, not about:blank)
and asserts that 3 back-to-back beginFrame calls each return non-empty
screenshotData. Catches the 148 soft-failure mode; falls back to
Page.captureScreenshot.
producer/plan: plan() didn't copy local assets (style.css, script.js, etc.
referenced by relative URL) into planDir/compiled/. The in-process file
server serves these from projectDir, but the distributed chunk worker's
file server only sees compiledDir. Result: every composition with external
local files rendered as unstyled HTML. Now plan() pre-seeds compiledDir
with cpSync(projectDir, ..., {dereference:true}) before compileStage
overwrites the entry HTML, so the planDir is the self-contained bundle
the docstring claims.
producer/renderChunk: force forceScreenshot:true in the chunk worker's
EngineConfig. Chrome 148's BeginFrame screenshot wedge is content-dependent
— the engine probe (now improved) catches it for some pages but not all,
and the real capture loop hangs on composition-shaped content the probe
can't simulate. Page.captureScreenshot works on every chrome-headless-shell
build we've tested, and executeRenderJob already takes this path for
multi-worker mp4, so the distributed pipeline inherits the proven Linux
reliability profile.
Also lowers the harness's distributed-simulated PSNR floor to 45 dB.
The plan's 50 dB target was written for per-render comparison; against
the frozen baseline file, the in-process renderer itself drifts ~2 dB
due to libx264/JPEG-capture jitter, so 50 dB is empirically unreachable
for either mode. 45 dB tracks the observed ~47-48 dB floor and stays
well above the 30 dB fixture threshold.
Validated:
- font-variant-numeric in distributed-simulated: PASSED (PSNR ~48 dB
across 100 checkpoints, audio correlation 1.000).
- many-cuts surfaces a fourth Phase 3 issue: timing drift on compositions
with external script src= files. First ~5 frames render the
pre-script-execution state and later variants come in ~200 ms late vs
baseline. Tracking separately — the harness mode is correctly detecting
it as a regression, which is the point.

Phase 3 of the distributed rendering plan: the public distributed
primitives (see DISTRIBUTED-RENDERING-PLAN.md §11 Phase 3). This PR
adds `plan(projectDir, config, planDir)` which composes Phase 1 stages
and Phase 2 helpers into Activity A — the controller-side step that
materializes a self-contained planDir and a content-addressed planHash.
Composition:
1. validateNoGpuEncode — refuse GPU encoders/hardware GL up front.
2. runCompileStage — fails-closed on font fetch errors when called
from plan() (threaded through a new optional `failClosedFontFetch`
on CompileStageInput / compileForRender).
3. validateNoSystemFonts — refuse host-OS primary fonts.
4. runProbeStage — browser probe, near-zero when staticDuration > 0.
5. runExtractVideosStage (materializeSymlinks: true) — frames are
copied recursively into the planDir for S3/GCS round-trip.
6. runAudioStage.
7. Materialize the §4.1 layout under <planDir>/.
8. freezePlan — writes meta/{composition,encoder,chunks}.json +
plan.json, computes planHash from the on-disk bytes.
Adds:
- `services/distributed/plan.ts` exposing `plan()`, the public
`DistributedRenderConfig` / `PlanResult` types, plus helper
primitives `resolveChunkPlan` and `buildChunkSlices` for §6.2.
- `services/distributed/plan.test.ts` — chunking math + golden
planDir layout + planHash determinism across two `plan()` calls
on the same inputs.
- Implements the `freezePlan` body (previously skeleton-only) and
its `stripUndefined` helper so optional LockedRenderConfig fields
don't collide via the canonical-JSON undefined-rejection.
- Threads `failClosedFontFetch` through compileForRender →
compileStage → injectDeterministicFontFaces.
Existing in-process behavior is unchanged. The new flag defaults to
`false`/`undefined` for every existing caller. Only `plan()` flips
it on.

Part of Phase 2 of the distributed rendering plan (determinism hardening).
See DISTRIBUTED-RENDERING-PLAN.md §5.3 (banned in distributed mode) and
§9.3 (typed non-retryable failures).
Today `injectDeterministicFontFaces(html)` swallows external font-fetch
failures: a failed Google Fonts CSS request or woff2 download returns
empty arrays, the composition warns via `warnUnresolvedFonts`, and Chrome
falls back to system fonts. That fallback would silently desync chunk
workers in distributed mode (workers run in a Linux container that
doesn't have macOS / Windows system fonts), so distributed renders need
to fail closed.
This change adds an options bag to `injectDeterministicFontFaces`:
injectDeterministicFontFaces(html, {
failClosedFontFetch?: boolean; // default false
fetchImpl?: typeof fetch; // default global fetch
})
When `failClosedFontFetch === true`, any non-OK CSS response, any non-OK
woff2 response, and any network error during either fetch throws a typed
`FontFetchError` with `code === FONT_FETCH_FAILED`. When `false` (the
default), behavior is unchanged.
`fetchImpl` lets unit tests inject failing-fetch stubs without going over
the network.
The in-process caller (`htmlCompiler.ts`) continues to call
`injectDeterministicFontFaces(html)` without options and gets the legacy
behavior. Phase 3's `plan()` will pass `failClosedFontFetch: true`.
Producer regression baselines remain byte-identical: no caller flips the
flag.
10 unit tests at packages/producer/src/services/
deterministicFonts-failClosed.test.ts pin both branches (default
swallows network error / 404; locked throws FontFetchError with correct
code, URL, and family name) plus the "no fetch happens for bundled
fonts" carve-out.

and `data-font-family=…` attributes. If the PRIMARY family (first
entry in the comma-separated list) resolves to a host-OS / CSS-generic
family, throws PlanValidationError with code SYSTEM_FONT_USED.
- parseFontFamilyValue(value) — pure helper that splits a font-family
declaration value, stripping whitespace + quotes.
Banned primary families: sans-serif, serif, monospace, cursive, fantasy,
system-ui, ui-sans-serif, ui-serif, ui-monospace, emoji, math, fangsong,
-apple-system, BlinkMacSystemFont. Mirrors the GENERIC_FAMILIES list in
deterministicFonts.ts (deliberately a separate copy — they're two
different concerns that happen to overlap today).
Generic families remain acceptable as CSS fallbacks; only the primary
slot is rejected. `font-family: "Inter", -apple-system, sans-serif` is
fine; `font-family: -apple-system, BlinkMacSystemFont` is rejected.
No caller invokes the validator yet. Phase 3's `plan()` will run it on
the compiled HTML before freezing the plan, so chunk workers (Linux
containers without macOS / Windows system fonts) never see compositions
that would render differently between the controller and the workers.
In-process behavior is unchanged.
14 unit tests added to packages/producer/src/services/render/
planValidation.test.ts cover: clean compositions, missing font-family,
each banned primary family, data-font-family= surface, case-insensitive
matching, fallback acceptance, and parser edge cases.

Part of Phase 2 of the distributed rendering plan (determinism hardening).
See DISTRIBUTED-RENDERING-PLAN.md §5.3 (Banned in distributed mode) and
§9.3 (typed non-retryable failures).
Adds packages/producer/src/services/render/planValidation.ts:
- PlanValidationError — typed plan-time error carrying a `code` field
matching plan §9.3, so Phase 3 adapter retry policies (Temporal /
Step Functions) can mark these as non-retryable.
- validateNoGpuEncode(config) — throws with code BROWSER_GPU_NOT_SOFTWARE
when:
* config.useGpu === true — distributed retries must be byte-
identical, but NVENC/QSV/VAAPI produce different output across
machines.
* config.browserGpuMode !== "software" — hardware GL is bitwise
unstable across drivers; pairs with the runtime
assertSwiftShader check from PR 2.2.
The BROWSER_GPU_NOT_SOFTWARE constant is re-exported from
@hyperframes/engine (where PR 2.2 declared it) and re-exported again from
this module, so the Phase 3 distributed adapter can match the typed code
without a cross-package import.
No caller invokes the validator yet. Phase 3's `plan()` will run it
before freezing the plan, so banned configs fail fast with a typed
non-retryable error instead of leaking into a planDir.
In-process behavior is unchanged — the in-process renderer continues to
accept useGpu=true and browserGpuMode="auto".
9 unit tests at packages/producer/src/services/render/
planValidation.test.ts pin both gates and the precedence (useGpu checked
before browserGpuMode).

Part of Phase 2 of the distributed rendering plan (determinism hardening).
See DISTRIBUTED-RENDERING-PLAN.md §17.2 (PR 2.7 row).
Distributed renders mix audio once at `plan()` time against the
composition's declared duration; the actual assembled video duration is
`Σ(chunkFrames) / fps`. Even with closed-GOP concat-copy the absolute
result is deterministic, but downstream muxers (especially ffmpeg's
`-shortest` plus Apple's mov demuxer) are sensitive to ±1ms audio/video
drift and produce silent "audio cuts off early" or "video freezes on the
last frame" bugs.
Adds packages/producer/src/services/render/audioPadTrim.ts:
- buildPadTrimAudioArgs(audio, out, sourceSec, targetSec) — pure helper
that decides the operation (pad/trim/copy) and emits the matching
ffmpeg argv. Uses `apad=pad_dur=Δ` (re-encode to AAC because filters
can't combine with `-c:a copy`), `-t target -c:a copy` (trim is a
lossless AAC packet boundary snap), or a plain `-c:a copy` when the
delta is below ~1ms.
- padOrTrimAudioToVideoFrameCount(input) — probes the assembled video
for exact frame count (`-count_packets` + `nb_read_packets`, which
equals frame count when chunks were encoded with `-bf 0` as Phase 2's
PR 2.1 already enforces), probes the audio for current duration,
computes target = `frameCount * fpsDen / fpsNum`, runs ffmpeg with the
args from the pure helper. Probes and ffmpeg runner are injectable so
unit tests don't shell out.
Six-decimal-place seconds formatting avoids ffmpeg's inconsistent handling
of scientific notation in time args across versions.
No caller invokes either function yet — Phase 3's `assemble()` will run
this after the chunk concat-copy step, before muxing audio onto the final
mp4/mov output.
15 unit tests at packages/producer/src/services/render/
audioPadTrim.test.ts pin both layers: the pure arg builder for all three
operations (incl. NTSC fps), and the wrapper for normal flow, probe
failures, invalid video info, and ffmpeg failures.
In-process behavior is unchanged. The producer's existing
`muxVideoWithAudio` path in chunkEncoder is untouched.

Part of Phase 2 of the distributed rendering plan (determinism hardening).
See DISTRIBUTED-RENDERING-PLAN.md §5.2 (lastFrameCache row) and §17.2
(gating table).
Adds `discardWarmupCapture(session, frameIndex=0, time=0, innerCapture?)`
in packages/engine/src/services/frameCapture.ts. Performs one capture
through the standard `captureFrameCore` path, throws the buffer away, and
restores the session's perf and BeginFrame damage counters.
Distributed chunk workers need this because Chrome's BeginFrame screenshot
pipeline maintains a per-process `lastFrameCache`: when a captured frame's
`hasDamage` reports `false`, the screenshot path returns the previously
captured buffer. For chunk N (N > 0) the worker has no prior frame in its
cache, so the very first capture's `hasDamage` reporting diverges from
what an in-process render at the same absolute frame index would see (the
in-process renderer always has frame N-1 cached). Running a discarded
warmup capture before the first real capture primes the cache so chunk
output is byte-identical to in-process output.
The wrapper:
- Takes an injectable `innerCapture` so tests can stub the Chrome path
(default is the real `captureFrameCore`).
- Restores `session.capturePerf`, `beginFrameHasDamageCount`, and
`beginFrameNoDamageCount` after the inner call — even on error — so
warmup captures don't pollute `getCapturePerfSummary()` averages.
- Writes no file to disk.
In-process behavior is unchanged: no caller invokes the new helper yet.
Phase 3's `renderChunk()` will run it as the first step after
`initializeSession` resolves.
Re-exported from packages/engine/src/index.ts.
7 unit tests at packages/engine/src/services/
frameCapture-discardWarmup.test.ts cover the post-conditional contract:
single inner-capture invocation, perf/damage restoration on success,
restoration on error, no-fs-write.

Part of Phase 2 of the distributed rendering plan (determinism hardening).
See DISTRIBUTED-RENDERING-PLAN.md §4.3 (LockedRenderConfig.runtimeEnv) and
§5.2 (RENDER_SEEK_MODE row).
`fileServer.ts` reads several `PRODUCER_RUNTIME_*` and `PRODUCER_RENDER_*`
env vars at module-load time (RENDER_SEEK_MODE, RENDER_SEEK_STEP,
RENDER_SEEK_OFFSET_FRACTION, …) and bakes them into the served HTML's
RENDER_MODE_SCRIPT. Distributed chunk workers are separate processes that
may inherit a different environment, so the plan needs to freeze a
snapshot.
Adds `snapshotRuntimeEnv(env = process.env)` in
packages/producer/src/services/render/stages/freezePlan.ts. Captures keys
matching `PRODUCER_RUNTIME_` or `PRODUCER_RENDER_` prefixes into a fresh
plain object, ignoring everything else. Phase 3's `renderChunk` will
materialize the snapshot back into `process.env` before launching its
file server.
Also exports `RUNTIME_ENV_SNAPSHOT_PREFIXES` so the chunk-worker side can
apply the same prefix filter (asymmetric handling would leak stale
controller env into worker behavior).
The freezePlan function body remains a skeleton — Phase 3 owns the full
implementation. The snapshot helper is exported on its own so this gate's
unit test can pin the behavior without depending on the not-yet-written
freezePlan body.
In-process behavior is unchanged: no in-process caller invokes
freezePlan or snapshotRuntimeEnv yet.
9 unit tests at packages/producer/src/services/render/stages/
freezePlan.test.ts cover: prefix matches (both families), non-matching
keys ignored, undefined values skipped, fresh-object contract, and
default-to-process.env behavior.

Part of Phase 2 of the distributed rendering plan (determinism hardening).
See DISTRIBUTED-RENDERING-PLAN.md §5.2 (Math.random row) and §17.2
(gating table).
The existing `VIRTUAL_TIME_SHIM` freezes Date.now / performance.now / rAF
on a render seek but leaves `Math.random` and `crypto.getRandomValues` as
native non-deterministic. Compositions that paint stochastic visuals
through these APIs produce different pixels on distributed retries.
This change adds `buildVirtualTimeShim({ seedRandomFromFrame: boolean })`.
Default `false` returns a string byte-identical to today's
`VIRTUAL_TIME_SHIM` (pinned by a new unit test). When `true`, the script
additionally:
- Installs a Mulberry32 PRNG with a single uint32 state
- Reseeds the state from the current virtual time on every
`seekToTime(ms)` call (Knuth multiplicative hash + golden-ratio offset)
- Replaces `Math.random` with the PRNG output
- Replaces `crypto.getRandomValues` to fill the buffer from the PRNG
`VIRTUAL_TIME_SHIM` (the const consumed by `renderOrchestrator` +
`probeStage`) is now `buildVirtualTimeShim({ seedRandomFromFrame: false })`
— in-process behavior unchanged, producer regression baselines unaffected.
Phase 3 distributed primitives will pass `true` when building the chunk
worker's file-server scripts.
10 new unit tests at packages/producer/src/services/
fileServer-seededRandom.test.ts use node:vm to evaluate the shim in
isolated contexts and pin both branches:
- default emits no RNG override and leaves Math.random native
- locked emits the seeded block, produces identical sequences across
fresh VMs at the same time, and yields different sequences for
different times

Part of Phase 2 of the distributed rendering plan (determinism hardening).
See DISTRIBUTED-RENDERING-PLAN.md §5.2 (warmupTicks row) and §17.2 (gating
table).
The BeginFrame warmup loop in `initializeSession` is driven by wall-clock
during page load — different hosts accumulate different tick counts before
page-readiness completes. That shifts `session.beginFrameTimeTicks` and
yields non-byte-identical captures on distributed workers.
This change adds `lockWarmupTicks: boolean` (default false) to
`CaptureOptions`. When false, behavior is unchanged. When true, the loop
runs exactly `LOCKED_WARMUP_TICKS = 60` iterations regardless of page-load
wall clock, and `session.beginFrameTimeTicks` is computed from the
constant — pinning the baseline across hosts.
Refactoring:
- Extract `driveWarmupTicks(options, state)` as a pure helper. Tests
drive it with a stub `tick` callback and an injected `sleep`, so the
iteration-count contract is unit-testable without real Chrome.
- `initializeSession`'s warmup body is now a thin adapter that calls
`driveWarmupTicks` with a CDP-backed tick.
Producer regression baselines remain byte-identical: the in-process
renderer never passes `lockWarmupTicks: true`. Phase 3 distributed
primitives will flip it true when launching chunk workers.
11 new unit tests at packages/engine/src/services/
frameCapture-warmupTicks.test.ts pin both branches (unlocked drifts with
simulated load time; locked produces identical counts).

Adds packages/engine/src/utils/assertSwiftShader.ts:
- assertSwiftShader(page, readInfo?) — navigates to chrome://gpu, reads
the GL_VENDOR / GL_RENDERER rows from browserBridge.gpuInfo_, throws
SwiftShaderAssertionError ({ code: "BROWSER_GPU_NOT_SOFTWARE" }) if
the active backend isn't SwiftShader.
- readWebGlVendorInfo(page) — extracted helper so tests can stub the
info read without spinning up real Chrome.
- SwiftShaderAssertionError + BROWSER_GPU_NOT_SOFTWARE constant exposed
so the Phase 3 distributed adapter can match typed non-retryable
failures.
Re-exported from packages/engine/src/index.ts. No caller invokes it yet;

Adds two optional fields to EncoderOptions:
lockGopForChunkConcat?: boolean // default false
gopSize?: number // required when lockGopForChunkConcat=true
When the flag is true on the SW libx264 / libx265 paths, buildEncoderArgs
emits closed-GOP / forced-keyframe args so the resulting chunk file can be
losslessly concatenated (`ffmpeg -f concat -c copy`) with sibling chunks:
-g <gopSize>
-keyint_min <gopSize>
-sc_threshold 0
-force_key_frames "expr:eq(mod(n,<gopSize>),0)"
-x264-params "...:scenecut=0:open-gop=0:repeat-headers=1"
-x265-params "keyint=<gopSize>:min-keyint=<gopSize>:scenecut=0:open-gop=0:repeat-headers=1"
-bf 0 (added for h265 too when locked)
GPU encoders, vp9, and prores ignore the flag (their concat-copy story is
separate — see plan §7.2 / §8).

Stored via Git LFS (already configured for
\`packages/producer/tests/*/output/output.mp4\` in \`.gitattributes\`).
The Windows install failures (`ENOENT: failed copying files from cache to
destination for package @types/node` / `esbuild`) are caused by bun creating
workspace-scoped nested installs under
`node_modules/@hyperframes/<pkg>/node_modules/...`. Those nested paths only
exist because each workspace package pinned a different `@types/node` /
`esbuild` major:
- root: `@types/node ^25.0.10`, core: `^24.10.13`, cli/engine/producer: `^22`
- core/cli: `esbuild ^0.25.x`, producer: `^0.27.2`
Each major-version gap forces bun to install a workspace-scoped copy in a
deep `node_modules/@hyperframes/<pkg>/node_modules/<dep>/node_modules/...`
tree that bun can't reliably materialize on Windows GHA runners. Aligning
versions lets bun dedup to a single root-hoisted install per dep, and the
nested workspace block disappears from `bun.lock` entirely.
## Alignment
- `@types/node` → `^25.0.10` across root, core, cli, engine, producer
- `esbuild` → `^0.25.12` across cli, core, producer
- `tsx` → `^4.21.0` across producer (matches root + core)
## Source-level v25 compat (already in this PR)
@types/node v25 declares `File` as an interface (not a class) and exposes a
conditional global where `FormData.entries()` narrows to `[string, string]`
when an `onmessage` global is in scope. `packages/core/src/studio-api/routes/files.ts`'s
`value instanceof File` check was relying on the v24 class declaration —
already cast the iterator to `Iterable<[string, FileLike | string]>` in the
prior commit.
Two more v25 source fixes here:
- `packages/cli/src/commands/init.ts`
- `packages/cli/src/whisper/normalize.ts`
`Dirent.path` was removed in @types/node v25 (deprecated alias for
`parentPath` since Node 20.12). Drop the `?? e.path` fallback.
## Verification
Both install layouts now build clean end-to-end:
- `bun install` (isolated, default): full build green, 853 core tests pass,
typecheck green across all 7 packages
- `bun install --linker=hoisted` (Windows CI): same result
- `bun.lock` no longer contains any `@hyperframes/<pkg>/<dep>` nested
workspace entries — 70+ lines of nested install blocks gone
Pushing further to actually get Windows render verification green, not just
work around it.
## What's wrong on Windows
Bun 1.3's default `isolated` linker creates nested workspace junctions under
`packages/*/node_modules/` on Windows GHA runners. Those junctions don't
materialize reliably — Node's `realpathSync` returns `EPERM` on stat, and
ESM resolution returns `ERR_MODULE_NOT_FOUND`. Every Windows build since
PR #748 has tripped this in one of three places:
- `packages/producer/build.mjs` importing `esbuild`
- `packages/producer/scripts/generate-font-data.ts` reading `@fontsource/*`
- `packages/producer` running `tsc` to emit `.d.ts`s
Long-running bun bugs: oven-sh/bun#23615, #18354, #10146.
## Fix
**1. `--linker=hoisted` for the Windows install step** (workflow change,
Windows only). Hoisted layout puts deps as real directories at the workspace
root + workspace package node_modules. No junctions, no Windows-specific
path quirks. Linux CI keeps the default isolated linker; the lockfile is
linker-agnostic so `--frozen-lockfile` is still valid.
**2. Source-level FormData narrowing in `packages/core/src/studio-api/routes/files.ts`**
(needed because the hoisted layout exposes a `@types/node@25` typecheck
issue that the isolated layout hides). With v25 + an `onmessage` global in
scope, the ambient `FormData.entries()` infers `[string, string]` instead of
`[string, File | string]`, so the `value instanceof File` check breaks at
`TS2358`. Cast the iterator to a `[string, FileLike | string]` shape and
narrow via `typeof value === "string"`. Identical runtime behavior; works
under both v24 (isolated layout, what Linux CI sees) and v25 (hoisted, what
Windows CI sees with this change).
## Verification
- `bun install --frozen-lockfile` (isolated, default): full build green
- `bun install --frozen-lockfile --linker=hoisted`: full build green, core
typecheck passes, `@hyperframes/core` 853 tests pass
- Format/lint clean on both layouts
Two narrow fixes pulled out of a larger Windows-CI investigation:
## 1. Format check (`oxfmt`)
`packages/core/package.json` and `packages/shader-transitions/package.json`
had their `publishConfig` keys reordered to a non-canonical order by the
v0.6.1 release commit (`82fd2967`). Releases push directly to main without
going through PR CI, so the drift wasn't caught and `bun run format:check`
has been failing on every push since. Fix: re-run `oxfmt`.
## 2. `@hyperframes/cli` `build:fonts` skip-when-present
`packages/cli`'s `build:fonts` script regenerated
`packages/producer/src/services/fontData.generated.ts` unconditionally on
every cli build. The script reads `@fontsource/*` packages via
`require.resolve(...)`, which walks `packages/producer/node_modules/@fontsource/*`
junctions — these trip `EPERM: operation not permitted, stat` on Windows
GHA runners because of long-running bun-on-Windows workspace junction bugs
(see oven-sh/bun#23615, #18354, #10146).
`fontData.generated.ts` is committed to git, so the regeneration is only
needed when fonts actually change. Match the skip-when-present pattern
already in `@hyperframes/producer`'s own `build:fonts`. Doesn't fix the
Windows render verification end-to-end (the producer build itself still
trips junction issues — being tackled separately in #765), but at least
stops `cli build:fonts` from being its own failure point on Windows.
Move file-level helpers and inline blocks out of renderOrchestrator.ts
into focused render/* modules. executeRenderJob shrinks from ~897 to
~675 lines; renderOrchestrator.ts from 2725 to ~2104.
New under packages/producer/src/services/render/:
- hdrPerf.ts: HdrPerfCollector + helpers
- captureCost.ts: capture-cost + calibration helpers, plus a new
runCaptureCalibration helper that owns the BeginFrame->screenshot
fallback
- hdrMode.ts: resolveEffectiveHdrMode
- perfSummary.ts: buildRenderPerfSummary
- cleanup.ts: safeCleanup, cleanupRenderResources,
buildRenderErrorDetails
shared.ts adds createCompiledFrameSrcResolver,
materializeExtractedFramesForCompiledDir, createMemorySampler.
Moved symbols are re-exported from renderOrchestrator.ts for
backwards compatibility; tests update to import from the new paths.
No behavior change: producer smoke set is PSNR-identical to main
inside Dockerfile.test.
lefthook.yml: belt-and-suspenders fix so the filesize hook actually
skips .test.ts / .generated.ts files. The hook-level exclude regex
does not filter the staged_files expansion inside the shell loop,
so the loop now does its own check.
Resolve the compileStage TODO from PR #720. cfg.forceScreenshot is now
computed exactly once inside compileStage (after applyRenderModeHints)
and returned on CompileStageResult.forceScreenshot. The sequencer stores
it on a local captureForceScreenshot; downstream capture stages take
the value as an explicit parameter and derive their own engine config
rather than reading cfg.forceScreenshot.
Mid-pipeline mutations removed:
- renderOrchestrator.ts: the pre-compile alpha-output mutation moved
into compileStage so the resolution is one operation in one place.
- captureHdrStage.ts: stopped mutating caller-owned cfg; the layered
composite path now uses a local hdrCfg derived from cfg plus
forceScreenshot=true. The stage throws if called with
forceScreenshot=false to make the contract explicit.
- BeginFrame auto-worker calibration fallback: still flips capture mode
on a timeout, but flips the local boolean instead of cfg. The
screenshot-mode retry uses a derived cfg view.
captureStage / captureStreamingStage add a forceScreenshot input and
derive captureCfg (identity-equal to cfg when the values already
agree, so no extra allocation on the common path).
lefthook.yml: grandfather renderOrchestrator.ts and captureHdrStage.ts
in the new 500-line filesize hook (#748). Both pre-date the hook and
are actively being shrunk in the producer stages stack.
Unblocks Phase 3 chunked rendering: LockedRenderConfig.forceScreenshot
in the distributed plan is computed here and survives across processes
without depending on shared mutable state.
First of several focused PRs that flatten the runtime cycle between
the capture stages and `renderOrchestrator.ts` (documented as a known
follow-up across PRs 1.6 / 1.7 / 1.8 / 1.9).
`updateJobStatus` was the most-imported orchestrator helper: 5 of the
6 capture / encode / assemble stages reach back into the orchestrator
for it. Moving it to `render/shared.ts` (where the other small
cross-cutting utilities already live) breaks the runtime cycle for
five stages in one move:
- captureStage
- captureStreamingStage
- captureHdrStage
- encodeStage
- assembleStage
Each of those stages now imports `updateJobStatus` from `../shared.js`
at runtime, and the only thing they pull from `renderOrchestrator.js`
is type-only (`RenderJob`, `ProgressCallback`, etc.) — type imports
are erased at runtime, so no cycle.
The orchestrator's own internal call sites (`updateJobStatus(...)` for
the inline progress updates and the `complete` / `failed` / `cancelled`
transitions) are unchanged in body; they now import the function from
the same shared module.
Follow-up PRs will move:
- `executeDiskCaptureWithAdaptiveRetry` + capture-retry helpers (breaks
the captureStage cycle entirely)
- The six HDR helpers + `resolveCompositeTransfer` (breaks captureHdrStage)
- `collectVideoMetadataHints`, `collectVideoReadinessSkipIds`,
`materializeExtractedFramesForCompiledDir` (breaks extractVideosStage)

Comment + interface cleanup driven by the /simplify review. No code
change beyond removing dead fields.
- audioStage: drop unused `job: RenderJob` from `AudioStageInput` (the
stage destructures it but never references the value).
- encodeStage: drop unused `fps` + `useGpu` from `EncodeStageInput`;
read both from `job.config.*` inside the stage (matches the pattern
used by captureStage and captureStreamingStage).
- captureStreamingStage: drop the unused `captureDurationMs` field
from `CaptureStreamingStageResult` (sequencer never reads it — it
uses its own `Date.now() - stage4Start` for `perfStages.captureMs`).
Also drops the now-dead `streamStart` local.
- captureStreamingStage: rewrite the "Known follow-up" header comment
to drop the "PR 1.3.5" reference per `feedback_no_internal_track_names_in_source`.
- captureHdrStage: drop the "Lifted verbatim from `executeRenderJob`"
refactor-narration sentence in the header doc (the "Hard constraints
preserved verbatim" list below it is real long-term documentation
and stays).
- Sequencer call sites updated to drop the now-removed fields.

Final polish PR of the Phase 1 stack. Comment-only — zero code change.
After PRs #725, #726, #730, #731, #733, #734, the `executeRenderJob`
function now composes eight stage modules instead of inlining the
pipeline. Updates the file-level JSDoc to point at each stage module
and explains the orchestrator's residual responsibilities: shared
resource lifetime, perf counters, error diagnostics, and the
`try/finally` cleanup. Adds JSDoc on `executeRenderJob` itself
summarising what it returns and when it throws.
The function body is unchanged. The line count dropped from ~2,200
(pre-Phase-1) to ~880; the remainder is in-sequencer setup that doesn't
naturally compose into a stage (calibration, worker resolution, HDR
auto-detection, preset selection, final perf-summary assembly) plus
the orchestrator's `try/finally` resource ownership.
Verified inside `Dockerfile.test`: font-variant-numeric (1.000),
many-cuts (0.994), variables-prod (0.975), hdr-regression (1.000) —
4/4 PASS with audio correlations identical to every prior PR in the
Phase 1 stack.

Move the final two stages of `executeRenderJob` into their own files:
- `services/render/stages/encodeStage.ts` (Stage 5): handles both the
png-sequence path (rename + copy + audio sidecar) and the encoded path
(`encodeFramesFromDir` or `encodeFramesChunkedConcat`).
- `services/render/stages/assembleStage.ts` (Stage 6): runs
`muxVideoWithAudio` when `hasAudio`, otherwise `applyFaststart`.
Skipped for png-sequence (sequencer gates the call).
Both stages are mechanical extractions of small, self-contained blocks.
The sequencer's call sites preserve the same conditions and the same
`perfStages.encodeMs` / `perfStages.assembleMs` assignments.
Hard constraints preserved verbatim:
- The `updateJobStatus` payloads ("Writing PNG sequence" / "Encoding
video" at 75%; "Assembling final video" at 90%) fire from inside the
stages at the same code points.
- The png-sequence "no PNGs were captured" error throws verbatim.
- The png-sequence audio sidecar is only written when
`hasAudio && existsSync(audioOutputPath)`.
- `enableChunkedEncode` selects `encodeFramesChunkedConcat` vs.
`encodeFramesFromDir` with the same args.
- The mux + faststart error messages (`Audio muxing failed: ...`,
`Faststart failed: ...`) throw verbatim on `success: false`.
Removes the now-orphaned imports from the orchestrator:
`encodeFramesFromDir`, `encodeFramesChunkedConcat`, `muxVideoWithAudio`,
`applyFaststart`.
Verified inside `Dockerfile.test`:
- font-variant-numeric (1.000), many-cuts (0.994),
sub-composition-video (0.947), gsap-letters-render-compat (1.000),
hdr-regression (1.000) — 5/5 PASS, audio correlations identical to
prior PRs in the stack. Exercises encoded mp4 + HDR (encode + assemble
both run) and the streaming-fusion path (encode skipped by sequencer).

Move the Z-ordered HDR / shader-transition layered composite branch
(`if (useLayeredComposite)`) out of `executeRenderJob` into
`services/render/stages/captureHdrStage.ts`. The largest extraction by
LOC (~745 lines of body lifted verbatim) and the riskiest by cleanup
invariants. Body is lifted byte-for-byte — only the surrounding scope
changes.
Cleanup invariants preserved verbatim (design doc §11 flagged these
explicitly):
- `hdrEncoderClosed` / `domSessionClosed` flags gate the
defensive-close paths so they don't run twice when the success path
already closed.
- `hdrVideoFrameSources` is drained + cleared in the outer `finally`
regardless of how the body exited.
- `cfg.forceScreenshot = true` is set unconditionally inside the
layered path because `captureAlphaPng` hangs under
`--enable-begin-frame-control`.
Other invariants preserved:
- `hdrPerf` is created at the top of the stage and returned; the
sequencer's `finalizeHdrPerf` consumes it for the perf summary.
- The `Layered compositing frame N/M` `updateJobStatus` payload fires
at the same per-frame point with `25 + frameProgress * 55`.
- `composition` and `compiled` are read-only in the stage.
- `hdrDiagnostics` is mutated in place (counters incremented at the
same code points).
- `nativeHdrIds` is recomputed inside the stage from
`nativeHdrVideoIds` + `nativeHdrImageIds` (the sequencer's
computation is unchanged; the stage just doesn't need it passed in).
To support the extraction, the following symbols are newly exported
from `renderOrchestrator.ts`:
- Helper functions: `createHdrPerfCollector`, `addHdrTiming`,
`closeHdrVideoFrameSource`, `blitHdrVideoLayer`, `blitHdrImageLayer`,
`compositeHdrFrame`.
- Types: `HdrPerfCollector`, `HdrPerfTimingKey`, `HdrVideoFrameSource`,
`HdrImageBuffer`, `HdrCompositeContext`, `HdrTransitionMeta`,
`TransitionRange`.
These are internal helpers — the stage is currently the only consumer,
and the cycle (orchestrator imports `runCaptureHdrStage`; stage imports
helpers back) is safe at runtime. A future PR will consolidate the
helpers into a shared module (same follow-up planned for the capture
helpers in PRs 1.6 and 1.7).
Removes the now-orphaned imports from the orchestrator:
`openSync`, `fpsToFfmpegArg`, `spawnStreamingEncoder`,
`StreamingEncoder` type, `runFfmpeg`, `initTransparentBackground`,
`decodePngToRgb48le`, `queryElementStacking`, `TRANSITIONS`,
`crossfade`, `resampleRgb48leObjectFit`, `normalizeObjectFit`,
`TransitionFn` type, `createHdrImageTransferCache`.
Verified inside `Dockerfile.test`:
- **HDR fixtures (3/3 PASS)**: hdr-regression, hdr-hlg-regression,
vignelli-stacking — audio correlations 1.000 / 1.000 / 0.982.
- **Non-HDR fixtures (4/4 PASS)**: font-variant-numeric, many-cuts,
sub-composition-video, gsap-letters-render-compat — audio
correlations 1.000 / 0.994 / 0.947 / 1.000.
- 7/7 fixtures total pass with PSNR / audio correlations matching every
prior PR in the stack.
