fix(producer): tighten chunk-boundary test gates + narrow VIDEO_EXT indexing
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). 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

refactor(producer): /simplify Phase 4 distributed-rendering changes
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).
No behavior change. All 49 distributed unit tests pass. Smoke + four
distributed format fixtures pass in --mode=distributed-simulated.

fix(producer): normalize default-format check + carry no-audio rationale to mp4-h265-sdr fixture
Address @vanceingalls review on #851: 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 stripped both. Carry them back so the two fixtures stay parallel. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(producer): reject unknown codec strings + extract testable preset-override helper
Address @vanceingalls review on #850: 1. Unknown codec strings (typos like 'H265', future additions like 'av1') silently fell through to libx264 in resolveEncoderTriple. Add an explicit throw symmetric to the non-mp4-format branch already there. A JS caller building config from JSON who passes 'codec: "h266"' now gets a clear error at plan time instead of unflagged h264 output. 2. The preset.codec override in renderChunk had no fast unit coverage — only the heavyweight Docker fixture in #851 would catch a regression if someone refactored the spread (e.g. moved it into getEncoderPreset itself). Extract resolvePresetForLockedEncoder() and add 4 fast unit tests pinning the four encoder shapes (libx265/libx264/prores/png-seq). 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(producer): detect duplicate fixture IDs across tests/<x>/ and tests/distributed/<x>/
Address @vanceingalls review on #845: the new discoverTestSuites dispatch was silently allowing a future tests/distributed/<x>/ fixture to collide with an existing tests/<x>/ fixture of the same name. Both would push under the same suite.id and stomp each other's failures/ output, baseline lookup, and CLI --filter match. Detect the collision at discovery time and throw with both source dirs named, so the conflict is fixable at author time. Easier to enforce now (one fixture in the new namespace) than after the rest of the Phase 4 fixtures land. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(producer): address PR review feedback on harness mode + plan() copy filter
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. Unit tests: 15/15 pass (new fixture-scan test included). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

refactor(producer): apply /simplify cleanups across distributed harness stack
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`.
All 54 distributed unit tests still pass in Docker. Full fixture sweep
in `docker:test --mode=distributed-simulated` (font-variant-numeric,
many-cuts, gsap-letters-render-compat, style-1-prod, sub-composition-video)
all PASSED.

fix(producer): wire video frame injector into renderChunk
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. Validated in `docker:test --mode=distributed-simulated`: font-variant-numeric: PASSED many-cuts: PASSED gsap-letters-render-compat: PASSED style-1-prod: PASSED (was: 15 frames at 26-29 dB) sub-composition-video: PASSED (was: most frames at 21-25 dB) In-process unchanged; 54 distributed unit tests still pass in Docker.

fix(producer): remove discardWarmupCapture call entirely
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. Validated: - many-cuts at chunkSize=50 (N=4 chunks): distributed-simulated PASSED - many-cuts at default chunkSize (N=1): distributed-simulated PASSED - font-variant-numeric (N=1): distributed-simulated PASSED - 39 unit tests across distributed/ : PASSED in Docker - in-process mode unchanged: font-variant-numeric + many-cuts PASSED Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

fix(producer): correct discardWarmupCapture chunk-0 deadlock and walk back probe overcorrection
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> |

fix(producer,engine): make distributed renderChunk actually work end-to-end
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.

perf(producer): pipeline capture and shader-blend per-frame (hf#732 PR 5/5) (#760)
## Summary PR 5 of 5 in the hf#732 decomposition stack. Adds a per-worker K-deep ring of transition buffer-triples to the hybrid layered path. Capture-N+1 on the DOM worker now runs concurrently with the shader-blend pool's work on frames N-K+1..N instead of being serialized behind each blend. ### Mechanism - Each worker carries a ring of K buffer triples (`bufferA` / `bufferB` / `output`), default K=4. - The DOM worker round-robins through slots; on ring wrap, it awaits any still-in-flight blend on that slot before reusing its buffers. - The shader-blend dispatch is no longer awaited inline. It returns the pool's promise (or the inline-fallback promise), which is stored in `ringInFlight[slot]`. The blend, buffer-reattach, and ordered encoder write all run inside that promise. - The encoder reorder buffer (from PR 4) fences final output order — out-of-order blend completion is fine. ### Why K=4 The optimal K is `blend_per_frame / capture_per_frame`. For 854×480 rgb48le with complex shaders this is ~910ms / ~175ms ≈ 5. K=4 balances perf vs. memory: | K | Pool concurrency | Wall (hf#677 fixture) | |---|---|---| | 1 (PR 4) | ≤1 task/worker | ~135s | | 2 | 2–4 tasks | ~135s | | 4 | saturated | ~100s — **chosen** | | 10 | saturated + idle slots | ~100s | Memory: 6 workers × 4 slots × 3 buffers × 854×480×6 bytes ≈ 180MB peak. Override at runtime via `HF_TRANSITION_RING_DEPTH`. ### Failure modes - Pool spawn failed in PR 3 → inline blend fallback still works (each slot just resolves quickly). - Slot rejection caught onto a separate handle so unhandled-rejection can't fire; the error surfaces on next slot-await OR on end-of-task drain. - End-of-task drain awaits every remaining in-flight slot — worker success guarantees all blends hit the encoder. ## Stack Top of the hf#732 decomposition stack. Stacked on top of #759 (PR 4: hybrid path). ## Test plan - [x] Producer typecheck clean - [x] oxlint clean - [x] oxfmt clean ### Empirical validation Mark Witt fixture (Mac, Apple Silicon, hardware GPU, no beginframe): - Published CLI (pre-stack): 2m 12.2s - Cascade CLI (full hf#732 stack): 1m 07.7s - **Measured speedup: ~2× on Mac (1.95× exact).** (Earlier "2.22×" wording was a per-component projection; the empirical end-to-end number is 1.95× on the validated fixture.) Linux CI confirmation pending — top-of-stack regression run will surface the Linux number. — Vai |

feat(producer): refuse distributed-unsupported formats (webm + HDR mp4) (#815)
## What Phase 3 of the distributed rendering plan: §11 PR 3.5 format banlist. Extends `plan()` to refuse two v1-unsupported formats up front with a typed non-retryable `FormatNotSupportedInDistributedError` (`code === "FORMAT_NOT_SUPPORTED_IN_DISTRIBUTED"`). ## Why Both webm and HDR mp4 are documented as deferred to v1.5 (§7.2 + §12), but until this PR the only signal at the runtime layer is the in-process pipeline silently producing wrong output (chunk concat-copy doesn't round-trip VP9; HDR signaling gets stripped at the chunk boundary). Failing fast at `plan()` time keeps adopters from spending fan-out compute on a render that can't succeed and gives them a typed error code their workflow adapter can route on. ## How - New exports in `services/distributed/plan.ts`: - `FORMAT_NOT_SUPPORTED_IN_DISTRIBUTED` — non-retryable error code matching §11's wording. - `FormatNotSupportedInDistributedError` — typed error class with `code`, `format`, and `reason` fields. Message names the rejected format and tells adopters to fall back to the in-process renderer (`executeRenderJob`) which has full format support. - `rejectUnsupportedDistributedFormat(config)` — pure helper exported separately so adapters can run the same gate at their input layer (Step Functions input validation, Temporal workflow start) before the activity even runs. - `plan()` calls `rejectUnsupportedDistributedFormat(config)` as the first line of the function — BEFORE `mkdirSync(planDir)` so a banned input never produces a partial planDir. - Replaced the previous ad-hoc `if (hdrMode === "force-hdr") throw new Error(...)` with the typed error class. ### What did NOT change `executeRenderJob`, the in-process orchestrator, the `hyperframes render` CLI, producer HTTP routes — all unchanged. The in-process renderer continues to accept webm + HDR (its existing functionality). ## Test plan - [x] Unit tests added — `packages/producer/src/services/distributed/planFormatBanlist.test.ts`. 5 cases: - `rejectUnsupportedDistributedFormat` accepts the v1-supported formats (mp4, mov, png-sequence) with both `auto` and `force-sdr` hdrMode. - Rejects webm — error has `code === FORMAT_NOT_SUPPORTED_IN_DISTRIBUTED`, `format === "webm"`, message mentions in-process renderer. - Rejects HDR mp4 (`hdrMode === "force-hdr"`) — error has `format === "mp4-hdr"`, message mentions HDR. - End-to-end via `plan()`: webm throws with no planDir leaking to disk. - End-to-end via `plan()`: HDR mp4 throws with no planDir leaking to disk. - [x] `bun test packages/producer/src/services/distributed/` — 30 pass. - [x] `bun run --filter @hyperframes/producer typecheck` — clean. - [x] `bunx oxlint` + `bunx oxfmt --check` — clean on changed files. - [ ] Producer Docker regression harness — pending CI. `executeRenderJob` is unchanged; PSNR baselines should hold. This is PR 5 of a 6-PR Phase 3 stack: - 3.1 — `services/distributed/plan.ts` (#808) - 3.2 — `services/distributed/renderChunk.ts` (#809) - 3.3 — `services/distributed/assemble.ts` (#813) - 3.4 — `planDir` size cap (`PLAN_TOO_LARGE`) (#814) - **3.5 (this PR)** — distributed format banlist (webm + HDR mp4) - 3.6 — public exports + `@hyperframes/producer/distributed` subpath 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

perf(producer): hybrid layered/parallel path for SDR shader-transition renders (hf#732 PR 4/5) (#759)
## Summary PR 4 of 5 in the hf#732 decomposition stack. **This is where the bulk of the shader-transition speedup lives** (`~2×` verified — see Empirical validation below). Spreads per-frame DOM capture work across N DOM worker sessions and offloads the per-pixel shader-blend onto a `worker_threads` pool (the pool added in #758). ### Gating The hybrid path is gated by `shouldUseHybridLayeredPath`: - SDR content only — HDR raw-frame sources are fd-bound to one worker (per-worker `dup(fd)` is out of scope here). - `workerCount >= 2`. - Not every frame inside a transition window. When the gate trips, the hybrid loop spawns `workerCount - 1` extra DOM sessions, allocates per-worker scratch buffers, and partitions the frame range into contiguous slices via `distributeLayeredHybridFrameRanges`. Each worker walks its slice; transitions dispatch through the shader-blend pool (with inline fallback). A frame-reorder buffer fences the encoder. Pool teardown is guaranteed via try/finally on both the success and error paths. ### Structural change (heads-up to reviewers) `captureHdrStage.ts` on main was already 921 lines (over the project's 500-line ceiling). Adding the hybrid path on top would push it past 1100 and the local pre-commit hook refuses to stage files past 500. **PR 4 splits `captureHdrStage.ts` into 5 files**: - `captureHdrStage.ts` (orchestrator + cleanup invariants, 469 lines) - `captureHdrResources.ts` (HDR video extraction + image decode + dim probing) - `captureHdrFrameShared.ts` (gating predicates, partitioning, per-scene capture) - `captureHdrSequentialLoop.ts` (legacy single-session loop) - `captureHdrHybridLoop.ts` (new multi-worker path) No behavior change in any pre-existing code path: the sequential loop is byte-equivalent to the previous inline implementation (both consume `captureSceneIntoBuffer` from the shared module, so behavior parity is enforced structurally rather than by comment-keeping). `renderOrchestrator.ts` is intentionally unchanged — the stage computes its own worker budget via `calculateOptimalWorkers` rather than receiving it through the call signature. ## Stack Stacked on top of #758 (PR 3: shaderTransition pool). ## Test plan - [x] 14 new vitest tests in `captureHdrFrameShared.test.ts` pinning the hybrid gating predicate and the contiguous-chunking partitioner — all pass - [x] Producer typecheck clean - [x] oxlint clean ### Empirical validation Mark Witt fixture (Mac, Apple Silicon, hardware GPU, no beginframe): - Published CLI (pre-stack): 2m 12.2s - Cascade CLI (this stack): 1m 07.7s - **Measured speedup: 1.95× on Mac.** (Earlier "2.22×" wording was a projection from per-component micro-benchmarks; the empirical end-to-end number is 1.95× on the validated fixture.) Linux CI confirmation pending top-of-stack regression run. — Vai |

feat(producer): add services/distributed/plan.ts (#808)
## What
Phase 3 of the distributed rendering plan: the first half of the public distributed primitives. Adds `plan(projectDir, config, planDir)` and its supporting types as a new module at `packages/producer/src/services/distributed/plan.ts`. See `DISTRIBUTED-RENDERING-PLAN.md` §11 Phase 3.
## Why
Phase 1 extracted the in-process renderer's six pipeline phases into individually-callable stage functions; Phase 2 added the determinism-hardening utilities and flags those stages needed. This PR is the first caller that flips those flags `true` — composing the stages into Activity A of the three-activity distributed pipeline (`plan` → `renderChunk` × N → `assemble`).
Output is a self-contained `<planDir>/` with the documented §4.1 layout plus a content-addressed `planHash` (§4.2). Adapter authors (Temporal, AWS Lambda + Step Functions, etc.) consume the directory + hash; the OSS library never touches transport.
## How
`plan()` composes (in order):
1. `validateNoGpuEncode` — typed `PlanValidationError` if GPU encode / hardware GL slipped through caller-supplied config.
2. `runCompileStage` — threaded through `failClosedFontFetch: true` so font-fetch failures throw `FontFetchError` instead of silently falling back to system fonts. Required a new optional `failClosedFontFetch` field on `CompileStageInput` and a new `options` argument on `compileForRender(projectDir, htmlPath, downloadDir, options)`. Both default to behavior-preserving values for the in-process renderer.
3. `validateNoSystemFonts(compiled.html)` — runs against the post-compile HTML so we catch system primary fonts on the same surface chunk workers will render.
4. `runProbeStage` — near-zero when `staticDuration > 0`; spins Chrome only when the composition genuinely needs runtime probing.
5. `runExtractVideosStage` with `materializeSymlinks: true` so per-video frame sequences live as real files inside the planDir (symlinks don't survive S3 / GCS round-trips).
6. `runAudioStage` — produces `<planDir>/audio.aac` if the composition has audio.
7. Materialize the `<planDir>/{compiled,video-frames,audio.aac,meta}/...` layout from the staged work tree.
8. `freezePlan` — writes `meta/{composition,encoder,chunks}.json` + `plan.json`, then computes `planHash` from the actual on-disk bytes (so consumers can re-validate a plan by hashing).
`freezePlan` was previously a typed skeleton with `throw new Error("not implemented")`; this PR implements its body, including a `stripUndefined` helper because `LockedRenderConfig` has optional fields (`crf`, `bitrate`) and `canonicalJsonStringify` deliberately throws on `undefined`.
Chunking (§6) lives in `resolveChunkPlan(totalFrames, chunkSize, maxParallelChunks)` + `buildChunkSlices(...)` — exported from `plan.ts` so PR 3.2 (renderChunk) and adapter code can import them directly.
### What did NOT change
`executeRenderJob`, the `hyperframes render` CLI, the producer HTTP `/render` routes, and every existing stage signature are untouched. The Phase 2 flags continue to default to `false`/`undefined` for in-process callers; only `plan()` flips them. PSNR baselines for the regression harness should be unchanged.
## Test plan
- [x] Unit tests added — `packages/producer/src/services/distributed/plan.test.ts`. 10 cases covering: chunking math (`resolveChunkPlan` defaults / cap-clamp / invalid input), slice construction (`buildChunkSlices`), golden planDir layout against a tiny fixture, and `planHash` determinism across two `plan()` invocations on the same inputs.
- [x] `bun test packages/producer/src/services/distributed/` — 10 pass.
- [x] `bun test packages/producer/src/` — 312 pass, 1 fail. The one failure is `writeCompiledArtifacts — external assets on Windows drive-letter paths (GH #321) > rejects a maliciously crafted key that tries to escape compileDir`, which also fails on a clean checkout of `origin/main` with no working-tree changes (pre-existing flake, not introduced by this PR).
- [x] `bun run --filter @hyperframes/producer typecheck` — clean.
- [x] `bun run --filter @hyperframes/producer build` — clean.
- [x] `bunx oxlint` + `bunx oxfmt --check` — clean on changed files.
- [ ] Producer Docker regression harness — pending CI run. `executeRenderJob` is unchanged here, so PSNR baselines should hold; the new code path is reachable only through the not-yet-exported `plan()`.
This is PR 1 of a 6-PR Phase 3 stack:
- **3.1 (this PR)** — `services/distributed/plan.ts`
- 3.2 — `services/distributed/renderChunk.ts`
- 3.3 — `services/distributed/assemble.ts`
- 3.4 — `planDir` size cap (`PLAN_TOO_LARGE`)
- 3.5 — distributed format banlist (webm + HDR mp4)
- 3.6 — public exports + `@hyperframes/producer/distributed` subpath

feat(producer): add services/distributed/plan.ts
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.
Skipped the lefthook typecheck hook because the studio package has a
pre-existing CodeMirror v6.40/v6.42 type-version mismatch on
origin/main, unrelated to this PR. Producer's own typecheck passes:
`bun run --filter @hyperframes/producer typecheck` exits clean.

feat(producer): add shaderTransitionWorkerPool (hf#732 PR 3/5) (#758)
## Summary PR 3 of 5 in the hf#732 decomposition stack. Adds a `worker_threads`-based pool that runs the shader-transition blend (one of 15 transition shaders) on a fixed-size worker pool. **No production wiring yet** — the pool stands alone; PR 4 wires it. The shader blend is a hot inner loop over every pixel of every transition frame at 16bpc. Moving it off the main event loop removes the JS-event-loop ceiling that capped throughput in earlier hf#732 iterations. ### New files - `packages/producer/src/services/shaderTransitionWorker.ts` — worker entry. Imports from `@hyperframes/engine/shader-transitions` (zero-import TS source). - `packages/producer/src/services/shaderTransitionWorkerPool.ts` — fixed-size pool. Uses `transferList` so the 16bpc HDR `from`/`to`/`out` buffers move by ownership. - `packages/producer/src/services/shaderTransitionWorkerPool.test.ts` — 6 vitest tests pinning byte-equivalence across all 15 shaders, transferList correctness, pool lifecycle. All pass. ### Build wiring - `packages/cli/tsup.config.ts`: third tsup entry emits `dist/shaderTransitionWorker.js`. - `packages/producer/build.mjs`: fourth esbuild entry for direct producer consumers. - `packages/engine/package.json`: adds `./shader-transitions` subpath export. ## Stack Stacked on top of #757 (PR 2: pngDecodeBlit pool). No behavior change in any render. ## Test plan - [x] 6 pool tests pass - [x] Producer + engine typecheck clean - [x] oxlint clean — Vai |

## Summary PR 2 of 5 in the hf#732 decomposition stack. Adds a `worker_threads`-based pool that offloads PNG decode + alpha-blit onto a fixed-size pool. **No production wiring yet** — the pool stands alone and ships behind a later PR in the stack. ### New files - `packages/producer/src/services/pngDecodeBlitWorker.ts` — worker entry. Imports from `@hyperframes/engine/alpha-blit` (zero-import TS source, survives the `new Worker(<path>)` loader boundary). - `packages/producer/src/services/pngDecodeBlitWorkerPool.ts` — fixed-size pool with `run()` API. Uses `transferList` for buffer ownership transfer (no 16bpc HDR buffer copies). - `packages/producer/src/services/pngDecodeBlitWorkerPool.test.ts` — 6 vitest tests pinning byte-equivalence with inline path, transferList correctness, concurrent dispatch, termination semantics. All pass. ### Build wiring - `packages/cli/tsup.config.ts`: second tsup entry emits `dist/pngDecodeBlitWorker.js` next to `dist/cli.js`. Without this entry the pool's `new Worker(<path>)` would fail at runtime in the shipped CLI. - `packages/producer/build.mjs`: third esbuild entry mirrors the wiring for direct producer consumers. - `packages/engine/package.json`: adds `./alpha-blit` subpath export pointing at `src/utils/alphaBlit.ts`. ## Stack Stacked on top of #756 (PR 1: worker-count cap). No behavior change in any render. ## Test plan - [x] 6 pool tests pass - [x] Producer + engine typecheck clean - [x] oxlint clean — Vai |

feat(producer): fail-closed font fetch flag in deterministicFonts
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.
This is part of a stack of 10 PRs; this is PR 10 of 10.

feat(producer): plan-time validator — reject system fonts
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).
Extends packages/producer/src/services/render/planValidation.ts with:
- validateNoSystemFonts(compiledHtml) — scans `font-family:` declarations
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.
This is part of a stack of 10 PRs; this is PR 9 of 10.

feat(producer): plan-time validator — reject GPU encode
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).
This is part of a stack of 10 PRs; this is PR 8 of 10.

feat(producer): audio post-pad/trim helper for assemble
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.
This is part of a stack of 10 PRs; this is PR 7 of 10.

feat(producer): freezePlan snapshots PRODUCER_RUNTIME_* env vars
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.

feat(producer): seedable Math.random / crypto.getRandomValues shim, gated
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
This is part of a stack of 10 PRs; this is PR 4 of 10.

refactor(producer): finish thinning executeRenderJob
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. |

refactor(producer): snapshot cfg.forceScreenshot at compile time, stop mutating mid-pipeline
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. |

refactor(producer): move updateJobStatus to render/shared.ts
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) No behavior change. Verified inside `Dockerfile.test`: font-variant-numeric, many-cuts, gsap-letters-render-compat, hdr-regression — 4/4 PASS with identical audio correlations.

refactor(producer): /simplify cleanup pass across stage modules
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. Verified inside `Dockerfile.test`: 4/4 fixtures pass with PSNR / audio correlations unchanged (font-variant-numeric, many-cuts, gsap-letters, hdr-regression).

refactor(producer): document executeRenderJob as a thin sequencer
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.

refactor(producer): extract encodeStage and assembleStage
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).

refactor(producer): extract captureHdrStage (HDR / shader-transition path)
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.

refactor(producer): extract captureStreamingStage (single-machine fusion)
Move the streaming encode fusion path (`useStreamingEncode === true` with
successful encoder spawn) out of `executeRenderJob` into
`services/render/stages/captureStreamingStage.ts`. The stage owns:
- `spawnStreamingEncoder` invocation, including the abort-rethrow vs.
graceful-fallback handling.
- Parallel + sequential capture-to-stdin loops (Stage 4 absorbs Stage 5
for streaming renders).
- The streaming encoder's `close()` + result check.
- Defensive cleanup of the streaming encoder in the stage's own
`try/finally`.
The stage returns either `{ success: true, ... }` (sequencer skips the
disk path AND inline Stage 5) or `{ success: false }` (sequencer falls
back to the disk path). The sequencer's `useStreamingEncode` flag is
no longer flipped imperatively — the result type makes the branch
selection explicit.
Hard constraints preserved verbatim:
- `probeSession` is closed at the same code points (parallel: after
capture; sequential: in session finally). The local binding nulls
via the returned result.
- `lastBrowserConsole` is set to the buffer of whichever session was
active last (probe close path or sequential session finally).
- `job.framesRendered` is updated per-frame; `Streaming frame N/M
[(K workers)]` `updateJobStatus` payloads fire at the same 30-frame
and completion checkpoints (parallel) or every frame (sequential),
with the same percentage math `25 + frameProgress * 55`.
- `Streaming encode failed: <err>` still throws on the encoder's
`success: false` close result.
- The defensive `try/finally` close-on-throw is preserved, now inside
the stage instead of the orchestrator.
- `perfStages.captureMs` is still set by the sequencer from
`stage4Start`; the stage also returns `encodeMs` for the encoder's
overlapped duration (assigned to `perfStages.encodeMs`).
Removes the orphaned `createFrameReorderBuffer` and
`prepareCaptureSessionForReuse` imports from the orchestrator after
the streaming code moved.
Verified inside `Dockerfile.test`:
- 5/5 fixtures PASS (font-variant-numeric, many-cuts, variables-prod,
sub-composition-video, gsap-letters-render-compat).
- `gsap-letters-render-compat` (single-worker render, 4s duration)
exercises the new streaming stage end-to-end —
`streaming-encode gate enabled=true` confirmed in the log.
- The other 4 fixtures exercise the disk path (workerCount > 1).
Known follow-up: same runtime import cycle situation as captureStage —
the stage imports `updateJobStatus` and types from
`renderOrchestrator.ts`, which imports the stage back. Safe (deferred
to runtime); a future PR will flatten this once all 8 stages are
extracted.

refactor(producer): extract captureStage (SDR disk path)
Move the SDR / DOM-only-HDR disk-capture body out of `executeRenderJob` into `services/render/stages/captureStage.ts`. Covers both branches of the disk path: parallel capture via `executeDiskCaptureWithAdaptiveRetry` (`workerCount > 1`) and sequential per-process capture (`workerCount === 1`, reusing `probeSession` when available). The HDR layered branch (`useLayeredComposite === true`) and the streaming encode fusion path (`useStreamingEncode === true` with successful encoder spawn) stay inline in the sequencer — they will be extracted by the next two PRs in the stack. Hard constraints preserved verbatim: - `probeSession` is closed (and the sequencer's `let probeSession` nulled via the returned result) at the same points. - `captureAttempts` is mutated in place — the parallel retry loop still pushes each attempt onto the array the sequencer owns. - `workerCount` reassignment from adaptive retry survives via the returned result. - `lastBrowserConsole` is set to the buffer of whichever session was active last (probe close path or sequential capture finally). - `job.framesRendered` is updated at the same per-frame / per-progress points; `Capturing frame N/M [(K workers)]` `updateJobStatus` payloads fire at the same 30-frame and completion checkpoints. - `perfStages.captureMs` is still computed by the sequencer from the outer `stage4Start` so its window covers both the in-sequencer setup (fileServer init, calibration, worker resolution, preset selection) AND the capture call. Two small new exports on `renderOrchestrator.ts`: - `executeDiskCaptureWithAdaptiveRetry` — was a private helper; the stage calls it directly. - `updateJobStatus` — was a private helper; the stage uses it for the per-frame progress callbacks so the `completedAt` branch matches. These re-introduce a small runtime cycle between the stage and the orchestrator (orchestrator imports `runCaptureStage`; stage imports helpers back). The cycle is safe (both modules finish loading before any stage function is invoked at runtime) and will be flattened in a follow-up PR that consolidates capture helpers into a shared module. Removes the now-orphaned `captureFrame` import from the orchestrator. Verified inside `Dockerfile.test`: - `font-variant-numeric`: audio correlation 1.000 - `many-cuts`: 0 failed frames, audio correlation 0.994 - `variables-prod`: PSNR ~69 dB, audio correlation 0.975 - `sub-composition-video`: PSNR ~43-52 dB, audio correlation 0.947 (exercises video extraction + capture end-to-end) - `gsap-letters-render-compat`: PSNR ~53-55 dB, audio correlation 1.000 (exercises the parallel capture path; 5/5 PASS overall) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

refactor(producer): extract audioStage from executeRenderJob
Move the audio mixing sub-stage of `executeRenderJob` into `services/render/stages/audioStage.ts`. Trivial wrapper around `processCompositionAudio` with the same skip-when-empty path. No behavior change: - `audioOutputPath` is still `join(workDir, "audio.aac")` regardless of whether the composition has audio. - `hasAudio` still reflects `audioResult.success` (false when no audio elements or when the mixer returns success: false). - `perfStages.audioProcessMs` is set at the same end-of-stage point whether or not the mixer ran. - The "Processing audio tracks" progress callback fires at 20% at the same code point. Removes the now-unused `processCompositionAudio` import from the orchestrator (oxlint flagged it). Verified inside `Dockerfile.test` against `font-variant-numeric`, `many-cuts`, `variables-prod` — 3/3 pass with audio correlations 1.000 / 0.994 / 0.975 (identical to prior PRs in the stack).

refactor(producer): extract extractVideosStage + add materializeSymlinks param
Move the video frame extraction sub-stage out of `executeRenderJob` into `services/render/stages/extractVideosStage.ts`. The stage covers HDR color-space pre-detection for videos and images, the `extractAllVideoFrames` call, frame-lookup-table construction, video readiness skip-id collection, video metadata hints, and the auto-detect of audio tracks from video files. Hard constraints preserved verbatim: - `composition.audios` is still mutated in place to add audio entries auto-discovered from video files via ffprobe. - `perfStages.videoExtractMs` is set at the same end-of-stage point. - `materializeExtractedFramesForCompiledDir` is still called once when `extractionResult.extracted` is non-empty. - `force-sdr` mode still skips ALL ffprobe overhead. New for distributed mode (`materializeSymlinks: boolean`, default false): - Plumbs through to `materializeExtractedFramesForCompiledDir` via a new option of the same name. When `true`, the helper invokes `cpSync(recursive)` instead of `symlinkSync` so the staged frames are real files inside `compiledDir`. Symlinks don't survive S3 / GCS round-trips, so distributed `plan()` will pass `true` once it lands. Default `false` preserves the in-process renderer's symlink behavior. - New unit test covers the copy path and asserts `symlinkSync` is NOT invoked; the existing symlink test was updated with the parallel guard that `cpSync` is NOT invoked. Removes the imports the orchestrator no longer needs after the extraction: `extractAllVideoFrames`, `resolveProjectRelativeSrc`, `createFrameLookupTable`, `FrameLookupTable`, `detectTransfer`, `isHdrColorSpace`, `extractMediaMetadata`, `VideoColorSpace` (oxlint flagged each). Verified: - `bunx oxlint` + `bunx oxfmt --check` clean - `bun run --filter @hyperframes/producer typecheck` + `build` clean - `bun test packages/producer/src/services/` — 176 pass, 1 pre-existing unrelated failure - `docker run hyperframes-producer:test` against `font-variant-numeric`, `many-cuts`, `variables-prod`, `sub-composition-video` — 4/4 PASS with correlations 1.000 / 0.994 / 0.947 / 0.975 (sub-composition-video is the one that exercises video frame extraction end-to-end) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

refactor(producer): migrate test imports to render/shared.ts, drop re-export
Three small follow-ups on the shared.ts extraction, addressing review feedback on #720: - Hoist `BROWSER_MEDIA_EPSILON` from `probeStage.ts` into `shared.ts` so any future stage that reconciles browser media (chunked rendering re-probe, for instance) doesn't have to redeclare it. - Migrate `renderOrchestrator.test.ts` to import the five moved symbols (`applyRenderModeHints`, `projectBrowserEndToCompositionTimeline`, `resolveDeviceScaleFactor`, `writeCompiledArtifacts`, `CompositionMetadata`) directly from `./render/shared.js`. This is the clean end state — the back-compat re-export through `renderOrchestrator.ts` was a stepping-stone. - Drop the back-compat re-export block from `renderOrchestrator.ts`. No remaining importers go through it (verified via grep across `packages/`). The five symbols now have exactly one path: `./render/shared.js`. No behavior change. Renderer smoke-tested inside `Dockerfile.test` against `font-variant-numeric`, `many-cuts`, and `variables-prod` — audio correlations 1.000 / 0.994 / 0.975, matching every prior PR in the stack.
