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

feat(engine): open drawElement fast capture to Windows hardware GPU
Widen the default-on drawElement clamp from darwin-only to darwin|win32 (still requiring a non-software-GPU browser). The darwin restriction was a validation envelope, not an architectural limit — the CanvasDrawElement Chrome flag ships on every platform, and every safety layer that made the macOS default-on release (v0.7.38) survivable is platform-neutral: compile-time gates, the SwiftShader init gate, per-render worker-encode self-verification with screenshot fallback, and the blank guard. Worst case on an unvalidated D3D11 backend is the same as on Metal: verify catches a bad frame and the render re-runs on the screenshot baseline. Why now: 30-day telemetry shows ~206k non-CI hardware-GPU Windows renders (~78% of the win32 fleet, 18k installs) held on the slow screenshot path by the clamp — the second-largest perf population after macOS, carrying ~1,550 capture-hours/month in the DE-eligible >=700-frame band alone at a measured ~2x speedup opportunity. Instrumentation for the new cohort: drawElement session init now records the raw WebGL UNMASKED_RENDERER_WEBGL string (detectSwiftShader generalized to detectGpuBackend — same single evaluate, the string was previously read and discarded) and threads it session -> CapturePerfSummary -> RenderPerfSummary -> render_complete as `gpu_renderer`. drawElement damage proved compositor-backend-specific throughout the macOS rollout, so D3D11-cohort failures must cluster by ANGLE backend + GPU vendor (NVIDIA/AMD/Intel), not just `os`. The two DE clamp branches are extracted into a pure, unit-tested `resolveDefaultDrawElement` (platform + GPU mode + worker-encode + explicit opt-in), which also drops resolveConfig's cyclomatic complexity. The win32 streaming-encode compound tests collapse onto one shared helper. Linux stays excluded: that fleet is headless/Docker SwiftShader, where DE has no speedup and known rendering defects. Kill switches unchanged: PRODUCER_EXPERIMENTAL_FAST_CAPTURE=false, --experimental-fast-capture=false. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

feat(cli): surface extract-cache dir in doctor + add --frames-cache-dir sugar
Windows users with the OS temp dir on a small system drive have hit C: exhaustion mid-render (Slack ts=1784219488 · CLI v0.7.58 · win32 15 GB / 8-core, ~5500 frames). The engine already honors HYPERFRAMES_EXTRACT_CACHE_DIR for relocation, but the knob was undocumented and invisible in diagnostics — the reporter had to piece together a 4-flag compound workaround including EXTRACT_CACHE_DIR=off. Changes: - Extract the env-var resolver into a public engine API (resolveExtractCacheDir, defaultExtractCacheDir, EXTRACT_CACHE_DIR_DISABLED_ALIASES) with a typed resolution shape distinguishing "disabled by user" vs "default" vs "env override". - Add a Frames-cache check to `hyperframes doctor` that reports the effective directory, its free space, source (env or default), and fails with a relocation hint when <2 GB free at that mount. - Add `hyperframes render --frames-cache-dir <path>` as discoverable CLI sugar for the env var, including the opt-out aliases (off/none/false/0) and CWD-safe absolute-path resolution. - Document the flag in docs/packages/cli.mdx with the field-signal citation, and add a render example row for the Windows workflow. - Cover both surfaces with unit tests (6 doctor cases + 4 engine cases including all disabled-alias variants).

feat(engine): auto-disable streaming-encode on Windows software-GPU compound
Field signal ts=1784131903 (win32/x64, CLI 0.7.58, 156s UI-heavy): stable ONLY with four flags together — --workers 1 --no-browser-gpu --low-memory-mode + PRODUCER_ENABLE_STREAMING_ENCODE=false. Since --no-browser-gpu and --low-memory-mode already imply screenshot capture, three of the four flags are structurally coupled. Auto-detect the compound at resolveConfig time and disable streaming-encode on the caller's behalf; user explicit-set (PRODUCER_ENABLE_STREAMING_ENCODE or overrides.enableStreamingEncode) always wins. Composition duration is not known at the config layer, so the wire-up passes compositionDurationSec:undefined and the helper reduces to the three-condition compound (platform + softwareGpuForced + workers=1). The 4-arg helper stays exported for downstream callers that DO know duration (e.g., renderOrchestrator) and want the >120s guard. Trade-off documented in code + PR body: false positives possible for short (~<120s) Windows software-GPU single-worker renders. Mitigation is the explicit opt-in escape hatch. Emits a single [hyperframes] log line naming the trigger + how to opt back in, so operators can tell an auto-disable apart from an explicit opt-out. Adds streamingEncodeAutoDisabledOnWin32Compound internal provenance for downstream telemetry. Stack: PR #2 of 9 (base via/protocol-timeout-discoverability). Signed-off-by: Via |

fix(engine,producer): drive forceScreenshot from one authoritative local
Miguel R4 blocker on #2359: my R3 fix at renderOrchestrator only updated the observability copy, leaving the authoritative captureForceScreenshot local at compileResult.forceScreenshot (false for auto→software). The frameCapture side clamped its own local and correctly routed screenshot, but downstream orchestrator code overwrote observability back to beginframe from the still-false local at two sites: - Parallel-stream label at renderOrchestrator.ts:2293 mis-labelled the stream as 'beginframe' when actual capture was 'screenshot'. - capture_strategy telemetry at renderOrchestrator.ts:2440-2450 overwrote the earlier observability correction, so the final captureMode observation flipped back to 'beginframe' while the engine actually captured screenshot. Fix: extract the clamp into a caller-facing helper applyConcreteGpuScreenshotClamp(current, resolvedGpuMode, cfg) that returns the (possibly-promoted) new boolean. Callers assign it back to their authoritative local, so routing + telemetry + strategy code read one value. Changes: - packages/engine/src/config.ts: new exported applyConcreteGpuScreenshotClamp; delegates to shouldClampToScreenshotForConcreteGpu but computes the caller's final value, not just the clamp decision. Reads the programmatic opt-out from cfg.forceScreenshotExplicitlyOptedOut. Idempotent on already-true input. - packages/engine/src/index.ts: export the new helper. - packages/engine/src/services/frameCapture.ts: replace the inline OR expression with applyConcreteGpuScreenshotClamp. - packages/producer/src/services/renderOrchestrator.ts: assign result into the AUTHORITATIVE captureForceScreenshot local (was updating only observability). Downstream parallel-stream label at :2293 and capture_strategy telemetry at :2440-2450 now read the corrected value. Tests: 6 new caller-level cases for applyConcreteGpuScreenshotClamp covering the exact matrix Miguel called out: - resolved software + default false → promotes to true (screenshot) - resolved software + programmatic opt-out → stays false (BeginFrame) - resolved hardware + default false → stays false - resolved software + already-true → stays true (idempotent) - resolved software + env PRODUCER_FORCE_SCREENSHOT=false → stays false - resolved software + undefined cfg → promotes to true (frameCapture path) Local: 67/67 engine config tests pass (was 61). oxfmt clean. |

fix(engine): carry programmatic forceScreenshot opt-out to concrete-resolved site
Miguel R3 blocker on #2359: the runtime helper only checked the env opt-out (PRODUCER_FORCE_SCREENSHOT=false), silently defeating the documented programmatic escape hatch (overrides.forceScreenshot === false) on the browserGpuMode:'auto' → software probe path. At the concrete-resolution site the boolean forceScreenshot === false is ambiguous between default and explicit opt-out — resolveConfig sees the provenance but the runtime helper does not. Fix: persist provenance on the resolved config. - New INTERNAL EngineConfig field forceScreenshotExplicitlyOptedOut, set by resolveConfig when EITHER env or programmatic explicit-false is present. Purpose-documented in the type as 'not intended to be set by callers'. - shouldClampToScreenshotForConcreteGpu gains an opts.programmaticOptOut parameter; returns false early when set. Env stays as the third arg (backward compatibility with existing tests). - frameCapture.ts and renderOrchestrator.ts pass config.forceScreenshotExplicitlyOptedOut through at both call sites, so the auto→software probe path preserves the same escape hatches as literal browserGpuMode:'software'. New tests: 5 additional cases across the helper (programmatic opt-out alone; programmatic beats missing env) and resolveConfig provenance (programmatic sets flag; env sets flag; neither leaves it undefined). Local: 61/61 engine config tests pass (was 56). |

fix(engine,producer): apply software-GPU screenshot invariant at concrete-resolved point
Addresses Miguel's R1 blockers:
1. `browserGpuMode: "auto"` that runtime-probes to software slipped past the
`resolveConfig` clamp — that clamp only sees the pre-resolve string. Add
`shouldClampToScreenshotForConcreteGpu(resolvedGpuMode, currentForceScreenshot, env)`
in `packages/engine/src/config.ts` and apply it at BOTH concrete-resolution
sites:
- `packages/engine/src/services/frameCapture.ts`: downgrades `preMode`
from "beginframe" to "screenshot" when resolved GPU is software (respects
`PRODUCER_FORCE_SCREENSHOT=false` env opt-out), fixing the routing.
- `packages/producer/src/services/renderOrchestrator.ts`: updates
`captureObservability.forceScreenshot` (and thus `captureMode`) at the
same call site, fixing the observability truth on the auto → software
case.
2. New unit tests in `config.test.ts`:
- Documents the auto-branch gap (resolveConfig leaves auto as
forceScreenshot=false — the runtime companion closes it).
- 5 branch tests on `shouldClampToScreenshotForConcreteGpu` covering
software / hardware / already-forced / env-opt-out / non-"false" env
values.
Full suite: 56/56 pass.
Scope narrowing on Blocker 2: the distributed rendering path at
`packages/producer/src/services/distributed/plan.ts:753-754` and
`renderChunk.ts:462-466` explicitly hardcodes `browserGpuMode:"software",
forceScreenshot:false` post-resolveConfig and stays outside this PR's
invariant boundary. `compileStage` may still flip it to true for alpha
formats, but generic MP4 distributed renders on SwiftShader hosts remain
BeginFrame. That's a separate architectural cleanup (needs its own
behavior-change trace); the PR body now scopes the invariant to the
in-process CLI/orchestrator path.

fix(engine): software-GPU browsers imply screenshot capture
When `browserGpuMode === "software"`, set `forceScreenshot = true` in `resolveConfig`. Explicit opt-outs (`PRODUCER_FORCE_SCREENSHOT=false` or `overrides.forceScreenshot === false`) are honored. This is defense-in-depth on top of the existing platform gates: 1. Linux + software (SwiftShader host) skips BeginFrame, avoiding the compositor stall on shader-heavy frames under CPU raster (same motivation as the closed PR #822). 2. `renderOrchestrator`'s reported `captureMode` field is derived from `cfg.forceScreenshot ? "screenshot" : "beginframe"` — without this clamp it misreports `"beginframe"` for the actual screenshot capture on darwin + software. 3. Any new BeginFrame or drawElement entry point that forgets to gate on GPU mode still routes to screenshot here. Does NOT fix SwiftShader-on-darwin text-rasterization artifacts (an ANGLE-SwiftShader issue on macOS text — the fix there is to use `--browser-gpu`, which routes to `--use-angle=metal`). |

feat(engine,producer): drawElement fast-capture default-on with runtime self-verification safety net (#1998)
* feat(engine,producer): drawElement fast-capture default-on with runtime self-verification safety net Flip useDrawElement + worker-encode defaults on (HF_DE_BATCH default 4), clamped in resolveConfig to hosts where drawElement can engage (macOS + hardware-GPU browser) so page-side shader compositing is untouched everywhere else; explicit env opt-in keeps attempt-and-gate semantics. Safety net makes default-on safe: the compile/init gates catch predictable incompatibility; this catches the intermittent residue no static analysis can see (stale paints, dropped background images, transient blank frames). - engine: captureDeVerificationFrames — K=4 (HF_DE_VERIFY) ground-truth screenshots at init, after gates + armStaticDedup, BEFORE canvas injection (post-injection screenshots show the canvas bitmap, not the DOM). Runs the video-injection hook per sample; double-captures so rAF-driven text counters settle (a single immediate screenshot captures stale text and false-positives). Skips png, <10 frames, implausible __hf.duration (infinite-repeat GSAP sentinel). - producer: guardFrame on both worker-encode drains — rolling-median blank guard with retry-once at drain (byte-identical retry ⇒ deterministic dark frame, accepted; retry save/restores the static-dedup anchor) + ffmpeg PSNR self-verify vs ground truth (HF_DE_VERIFY_MIN_DB, default 32dB; natural agreement ≥45dB, damage ≤25dB). Breach dumps the frame pair to tmpdir and throws DrawElementVerificationError. - orchestrator: one-shot retry — on verification error the whole render re-runs with forceScreenshot (slower, never wrong); telemetry flag deSelfVerifyFallback. - tooling: de-canary-suite.sh (7-comp release gate with expected verdicts), de-gatecheck.sh (init-only corpus routing classifier), we-render.mjs. Validated: canary suite 7/7; 611-comp routing sample 54% drawelement / 37.5% gated / 8.3% comp-defect; 12/12 risk-band renders clean on bare defaults (48/48 verify samples); engine suite 888 passed; caught two real intermittent damage classes in the wild (background-image drop, root-props offset) that previously shipped silently. Kill switches: PRODUCER_EXPERIMENTAL_FAST_CAPTURE=false, HF_DE_WORKER_ENCODE=false, HF_DE_BATCH=0, HF_DE_VERIFY=0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(engine,producer): harden the drawElement self-verification net (max code-review findings) 15 confirmed findings from the adversarial review of the default-on flip; the load-bearing five: - Ground-truth capture no longer scrubs GSAP state: seek(0) + forced frame FIRST (lazy .from()/overlap tweens record start values on first seek — mid-timeline scrubs corrupted them for the whole render, and since DE frames and truth shared the corruption, PSNR passed on damaged output), then ascending even-spread fractions, page left at frame 0. - Default-on drawElement is confined to the verified path: resolveConfig requires worker-encode (the drain that runs the net), the orchestrator disengages the default when the render takes the disk path or parallel capture (no drain verification there), and closes a drawElement-initialized probe session rather than letting the unverified path reuse it. Explicit PRODUCER_EXPERIMENTAL_FAST_CAPTURE=true keeps old attempt-and-gate behavior. - Blank-frame retry can no longer splice wrong-frame pixels: recapture goes through recaptureDrawElementFrameForVerify — no static-dedup shortcut (lastEncodeResult runs ahead of the drain) and no "No cached paint record" screenshot fallback (post-injection that captures the canvas = the LAST drawn frame); any recapture failure falls back the whole render. - Verify indices derive from the producer-resolved duration (CaptureOptions.compositionDurationSeconds) instead of raw __hf.duration, so samples always land inside the drained range. - The platform clamp accepts "auto" GPU mode — the stock CLI resolves auto, and the literal-"hardware" clamp made default-on a no-op for the primary audience (masked in validation by explicitly-set env). Also: NaN-safe env parses (HF_DE_VERIFY / HF_DE_VERIFY_MIN_DB / HF_DE_BATCH); video comps skip verification when the session has no frame injector (probe sessions — black-video truth false-positived); psnr infrastructure failures skip the sample instead of failing the render; boundary-saturated sample indices are skipped; shader-transition comps prefer page-side compositing over default drawElement and compile-gated comps get page-side compositing restored; observability.clearFailure un-brands the recovered first streaming attempt; canary suite exempts known-marginal "any" comps from the cross-path PSNR gate; dead we-render options removed; clamp tests pin their env. Validated: canary suite 7/7; auto-GPU bare render engages the full stack; disk-path and worker-encode-off renders disengage default drawElement; malformed HF_DE_VERIFY_MIN_DB still verifies at the default threshold; engine suite 890 passed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(engine,producer): review fixes — PSC intent, verify-threshold clamp, fail-closed canaries Addresses miguel-heygen's review on #1998: - Page-side compositing restore preserves explicit caller intent (blocker): resolveConfig now records pageSideCompositingAutoDisabled only when IT turned page-side compositing off because drawElement was on; the compile-time drawElement gates restore page-side compositing only when that flag is set. An explicit enablePageSideCompositing:false from the programmatic API or HF_PAGE_SIDE_COMPOSITING=false stays off. Pinned by two config tests. - HF_DE_VERIFY_MIN_DB clamped to [10, 60] with a warning on out-of-range values: below ~10dB the check passes severe damage; above ~60dB natural encoder differences force a screenshot fallback on every verified render. - de-canary-suite.sh + de-gatecheck.sh run under set -euo pipefail with explicit `|| true` on expected-nonzero commands (render exits handled by the suite's own checks, grep no-match, kill/pkill/wait races) and a hard FAIL when the PSNR compare produces no value — release canaries fail closed. Full suite re-run green (7/7) under the new flags. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

feat(engine,cli): drawElement fast-capture config + CLI flag (#1916)
## drawElement fast-capture — config + CLI flag (stack 1/6) Foundation layer for the drawElement fast-capture feature: the config surface and CLI/Docker plumbing that the rest of the stack builds on. ### What this adds - **`packages/engine/src/config.ts`** — new config fields for fast capture: `useDrawElement` / `enableDrawElementWorkerEncode` (macOS-GPU `drawElementImage` capture + worker-offloaded JPEG encode), resolved from env in `resolveConfig` (env `HF_DE_WORKER_ENCODE`). Wired alongside main's existing `staticFrameDedup` (unified downstream in 4/6). - **`packages/cli/src/commands/render.ts`** — `--experimental-fast-capture` flag → sets `experimentalFastCapture`; `--debug` passthrough. - **`packages/cli/src/utils/dockerRunArgs.ts`** — pass the fast-capture env through to the container. - **`.github/workflows/fast-video-validation.yml`** — CI job validating fast-capture renders. - `.oxlintrc.json` / `.fallowrc.jsonc` — ignore-pattern housekeeping for the new paths. ### Notes - Config-only + entrypoint; no capture behavior yet (that's 2/6–4/6). - Tests: `config.test.ts`, `dockerRunArgs.test.ts` added. --- **Stack (drawElement fast-capture, rebased onto current `main`, supersedes #1295 + #1444):** 1. **#1916 config + CLI** ← you are here 2. #1917 drawElementImage capture service 3. #1918 3D projection + compositor-effect risk gate 4. #1919 frame-capture core (routing, worker-encode, static-dedup unification) 5. #1920 producer render stages + remote bg-image localizer 6. #1921 lint rule + player media sync ⚠️ Intermediate PRs (1–5) are split by package boundary for review and **do not each compile independently** (cross-file deps); the complete feature is green at the stack tip (#1921) — tsc-clean on engine + producer, 231 tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

perf(engine): extraction cache on by default with atomic publish and LRU gc (#1901)
* perf(engine): extraction cache on by default with atomic publish and LRU gc Warm re-renders now skip source-video frame extraction entirely (video_extract 400ms -> 13ms on a 4-video composition; outputs are pixel-identical, PSNR inf). What made default-on safe: - Atomic entry publish: frames extract into a unique .partial-<pid>-<uuid> dir, the completion sentinel is written there, and the dir is renamed into the final key atomically. Concurrent renders sharing a cache can duplicate work but can never serve a torn entry (previously documented as single-writer only). - Size-capped LRU gc: best-effort sweep after extraction evicts oldest-used entries past a 2 GiB default budget (HYPERFRAMES_EXTRACT_CACHE_MAX_MB) and clears crashed writers' partials. Entries younger than 60 min are never evicted so live renders keep their frames. - Default cache dir: <tmpdir>/hyperframes-extract-cache-<uid>. Opt out with HYPERFRAMES_EXTRACT_CACHE_DIR=off (or none/false/0); a non-writable dir degrades to uncached with a single warning instead of failing the render. * fix(engine): harden extraction cache publish and surface cache ops signals Review hardening for the default-on extraction cache: - Bypass the cache for HDR-converted intermediates: the key snapshot describes the original source, so publishing converted frames under it would poison later plain-SDR renders of the same trim. (The follow-up transform-keyed change re-enables caching for these.) - publishCacheEntry TOCTOU: adopt a concurrent writer's completed entry both before removing an apparently-stale dir and after a failed retry rename, so a winner's publish is never destroyed or reported as a failure. - Observability for the failure paths: cachePublishFailures, cacheGcEvictions, cacheGcBytesFreed, and cacheAgedPartialsCleared on ExtractionPhaseBreakdown; gcExtractionCache now returns sweep stats. * fix(engine): sweep superseded cache generations in gc After a SCHEMA_PREFIX bump, old-generation entries (hfcache-v2-*) no longer matched the sweep's prefix filter and would orphan their disk forever. The gc now matches any hfcache-v* generation; superseded entries never receive sentinel touches, so the LRU evicts them first. |

Four independent capture-infra hardening changes for the P2-5 failure bucket (~15K err / ~7K users): - protocolTimeout auto-scales by device-scaled output area (applied before probe launch, since it's immutable post ppt.launch()). - Single bounded transient retry (MAX_TRANSIENT_CAPTURE_RETRIES=1) on Target closed / Page crashed in the parallel disk-capture path; abort short-circuits before retry. - Narrow OOM classification (Set maximum size exceeded etc., disjoint from transient) → actionable guidance naming output dims. - StreamingEncoder.getExitError() threads FFmpeg's real exit reason into frame-0 encoder-death errors.

feat(engine): static-frame dedup default-on + render telemetry (#1549)
* feat(engine): static-frame dedup for screenshot capture (opt-in) Skip re-seeking + re-screenshotting frames byte-identical to their predecessor. A frame is dedupable iff no GSAP tween or clip cut is active in it or its predecessor (predicted from window.__timelines + clip schedule) AND an empirical anchor-compare confirms it. Opt-in HF_STATIC_DEDUP=true, default off. Correctness (designed for the multi-worker / distributed render paths): - Reuse is keyed by the ABSOLUTE composition frame (derived from the frame's time), NOT the captureFrameCore frameIndex arg — chunked/parallel callers pass a chunk- relative index. Validated lossless (PSNR=inf) on both single- and multi-worker renders of a static-hold comp. - verifyStaticFramesSafe checks EVERY run (no longest-first budget truncation that left runs armed-but-unverified), and samples each run's FIRST reused frame, its END, and interior points at a stride; a hard cap disables dedup rather than trust an unverified set. - Conservative arming: skipped when capture mode != screenshot (BeginFrame tick semantics + the verifier's screenshot path wouldn't transfer), when a before-capture hook is set (per-frame video injection), when page-side compositing is active (shader / drawElement composite the plain verification screenshot can't reproduce), and when any data-start is a non-numeric reference expression the clip-boundary parser can't protect, or duration is unknown/zero. - Session reuse (prepareCaptureSessionForReuse) resets lastFrameBuffer + dedup counter so a probe/prior-render buffer can't bleed into the first static frame; the armed set is kept (same-composition reuse). Cost calibration bypasses dedup for its sparse, non-contiguous sample sweep, then restores the armed set. - HF_STATIC_DEDUP_SAMPLES is NaN-guarded. Disqualifies on signals the GSAP predictor can't see: video, canvas/webgl, zero tweens, running CSS/WAAPI animation. Pays on static-hold content (title cards, slideshow/kiosk loops, data-viz pauses); no-op on continuously-animated comps. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(engine): static-frame dedup default-on + render telemetry Flip dedup from opt-in (HF_STATIC_DEDUP=true) to default-on (opt-out HF_STATIC_DEDUP=false). Verification (verifyStaticFramesSafe) is the safety net that keeps reuse sound at scale. Add end-to-end dedup observability. The capture session records enabled / armed / skipReason / predicted; these surface via CapturePerfSummary -> a dedupPerfs accumulator (disk sequential + parallel AND streaming sequential + parallel) -> aggregated into RenderPerfSummary.staticDedup (OR armed, SUM frames across workers) -> render_complete props static_dedup_{enabled,armed,skip_reason, predicted_frames,reused_frames}. skip_reason is a low-cardinality code: capture_mode | video_injection | page_composite | ineligible | verification_failed. Distributed chunks run on Linux/beginframe where dedup never arms, so they pass a throwaway dedupPerfs sink (no per-chunk reporting). Tests: aggregation logic (OR/SUM/skip-reason) + opt-out passthrough. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(engine): address review on dedup default-on + telemetry Review feedback (miga-heygen) + self-review fixes: - Retry double-count: executeDiskCaptureWithAdaptiveRetry pushed worker dedup perf inside the retry loop, so an adaptive retry counted frames twice (reused/predicted could exceed totalFrames). Reset dedupPerfs at the start of each attempt — retry now REPLACES rather than accumulates; common no-retry path is unchanged. - Opt-out parsing: HF_STATIC_DEDUP now disables on {false,0,off} case/space-insensitive (was strict !== "false", so `False`/`0` silently kept dedup on — the kill-switch could no-op). - Verification budget vs drift: verifyStaticFramesSafe returns {badFrame, budgetExhausted}; armStaticDedup reports a distinct `verification_budget` skip reason so a telemetry spike means "raise HF_STATIC_DEDUP_SAMPLES", not "compositions are non-static". - Index idiom: captureFrameCore now uses Math.floor(time*fps + 1e-9) (matches quantizeTimeToFrame) so the dedup lookup agrees with the frame the seek lands on even for non-exact times. - Stale "opt-in HF_STATIC_DEDUP=true" comments -> "opt-out HF_STATIC_DEDUP=false" across frameCapture.ts + types.ts. - Extract pushWorkerDedupPerfs helper (perfSummary.ts), used by the disk and streaming parallel paths — removes the duplicated push loop and drops captureStreamingStage back under the complexity threshold. - dedupPerfs is now required (not optional) on executeDiskCaptureWithAdaptiveRetry — a missing arg silently dropped telemetry. - Test: captureStreamingStage createInput() now provides the required dedupPerfs field. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(engine): address deferred dedup-review items - Derivable state: drop session.staticDedupArmed/staticDedupPredicted; derive both from session.staticFrames in getCapturePerfSummary (armed ⟺ non-empty set, predicted === size) so they can't desync. - Config altitude: HF_STATIC_DEDUP now resolves into EngineConfig.staticFrameDedup (resolveConfig, opt-out on {false,0,off}), alongside forceScreenshot/browserGpuMode — armStaticDedup reads config instead of process.env. Default-on preserved (missing config → enabled). - Lossy aggregation: aggregateDedup now reports DISTINCT skip reasons (sorted, `|`-joined) across diverging unarmed workers instead of just the first. - discardWarmupCapture: also snapshot/restore staticDedupCount and lastFrameBuffer so a warmup capture can't leak a phantom reuse or a stale buffer anchor into the real summary. - Convention: perfSummary-dedup.test builds its job via createRenderJob instead of `as unknown as RenderJob`. - Docs: verification_budget added to skip-reason lists.

feat(producer): auto low-memory safe render profile (#1225)
## What Adds an auto-detected **low-memory safe render profile**. On hosts at or below 8 GB total RAM, the render pipeline collapses to its cheapest shape instead of running multiple concurrent Chrome instances. When `lowMemoryMode` is active and the user hasn't passed `--workers`, the orchestrator: - **skips auto-worker calibration** — no throwaway second Chrome just to time 5 frames; - **pins to a single worker** — so the probe Chrome is reused for capture, never N concurrent; - **prefers screenshot capture over BeginFrame** — avoids the BeginFrame protocol-timeout → relaunch churn on slow hardware; - logs a one-line explanation of what it did and how to override. Builds on #1221 (merged), which fixed the calibration timeout cap, the `<= 8192` boundary, and added the CLI timeout flags. ## Why Reported in #1218 / #1219: renders on 8 GB laptops sit at low progress for minutes or stall. Root cause (per the triage thread) is architectural — the default pipeline launches up to 4 Chrome instances sequentially/overlapping (probe, calibration, capture, screenshot-fallback), each ~256 MB+, on machines with ~3 GB free. The concurrent browsers drive memory pressure that makes every CDP call slow and spikes V8 GC pauses. #1221 made the timeouts and memory flags *apply correctly*; this PR removes the expensive shape entirely on the machines that can't afford it, rather than tuning it. "Smarter by default." ## How - **`packages/engine/src/services/systemMemory.ts`** (new): one shared `isLowMemorySystem()` / `getSystemTotalMb()`, de-duplicating the `totalmem()` reads previously copied in `config.ts` and `browserManager.ts`. Threshold is inclusive (`<= 8192 MB`) — real "8 GB" hardware reports ~7600–8192 MB after firmware/iGPU reservations, so a strict `<` would skip the optimisation on the very hardware that needs it. - **`config.ts`**: new `lowMemoryMode` field on `EngineConfig`, resolved tri-state — explicit override → `PRODUCER_LOW_MEMORY_MODE` (on/off) → auto-detect from total RAM. - **`renderOrchestrator.ts`**: gate calibration off, pin workers to 1, force screenshot capture, and emit a safe-mode log line when `lowMemoryMode` is set and `--workers` is absent. - **`render.ts`**: `--low-memory-mode` / `--no-low-memory-mode` override (sets the env var the producer's `resolveConfig` reads) + docs table entry. Fully overridable: an explicit `--workers N` restores calibration-free parallelism; `--no-low-memory-mode` / `PRODUCER_LOW_MEMORY_MODE=false` restores the full default shape. ### Deliberately deferred (separate PRs) - **Reuse the probe session for calibration**: only executes on the tier *above* 8 GB (safe-mode skips calibration on the target boxes). A correct BeginFrame-mode reuse would lose calibration's fast-fail-to-screenshot timeout — real risk on a path the reported scenario never hits. Better scoped on its own. - **Retuning `calculateOptimalWorkers`'s `totalmem*0.5/256` memory model**: hot path for *all* renders incl. servers/Lambda, outside this PR's local-laptop scope. ## Test plan - [x] Unit tests added/updated — `systemMemory.test.ts` (8192 boundary cases), `config.test.ts` (tri-state env resolution + explicit-override precedence). Engine suite passes (25 relevant tests). - [x] `tsc` clean across engine/producer/cli; `oxlint` + `oxfmt` clean; removed an unused export so the `fallow --fail-on-issues` dead-code gate stays green. - [x] Documentation updated — `docs/packages/cli.mdx` render-flags table. - [ ] Manual testing on a real ≤ 8 GB host — not yet run; behaviour is unit-covered and the safe path (1 worker + screenshot) is already a supported render shape. Note: one pre-existing producer test (`rejects a maliciously crafted key…`) fails identically on `main` — environment-specific path test, unrelated to this change. |

fix: respect user timeouts on low-memory systems (#1221)
Closes #1219 ## Problem On 8GB RAM machines, renders time out at 5% with `Runtime.callFunctionOn timed out` during the duration probe. User-set timeout env vars (`PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS`) are silently ignored by the calibration path, and there are no CLI flags to control timeouts directly. ## Root causes 1. **Calibration timeout cap overrides user settings** — `createCaptureCalibrationConfig` used `Math.min(cfg.protocolTimeout, 30_000)`, meaning even if the user set 300s, calibration still capped at 30s. On slow hardware this causes unnecessary timeouts. 2. **8GB systems get no low-memory treatment** — `getLowMemoryFlags()`, `getGpuMemBudgetMb()`, `memoryAdaptiveCacheLimit()`, and `memoryAdaptiveCacheBytesMb()` all used `< 8192` as the threshold. Systems reporting exactly 8192 MB (common for 8GB machines) fell through to the "plenty of memory" path, getting no Chrome heap reduction or cache limits. 3. **No CLI flags for key timeouts** — Users had to discover the correct env var names (`PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS`, `PRODUCER_PLAYER_READY_TIMEOUT_MS`) by reading source. The non-existent `PUPPETEER_PROTOCOL_TIMEOUT` and `--browser-timeout` were common guesses that did nothing. ## Changes - `captureCost.ts`: `Math.min` → `Math.max` so the 30s calibration default is a floor, not a ceiling. User-set higher timeouts are now respected. - `browserManager.ts`: `>= 8192` → `> 8192` in `getLowMemoryFlags()` and `<= 8192` in `getGpuMemBudgetMb()` so 8GB systems get reduced Chrome heap and GPU memory budget. - `config.ts`: `< 8192` → `<= 8192` in `memoryAdaptiveCacheLimit()` and `memoryAdaptiveCacheBytesMb()` so 8GB systems get reduced frame cache limits. - `render.ts`: Added `--protocol-timeout <ms>` and `--player-ready-timeout <ms>` CLI flags, wired through `resolveConfig` overrides. - Updated calibration tests to match the new floor-not-ceiling behavior. - Added fallow suppressions for pre-existing unused exports in `captureCost.ts`. ## Test plan - [x] Engine config tests pass (`vitest run src/config.test.ts`) - [x] Browser manager tests pass (`vitest run src/services/browserManager.test.ts`) - [x] Calibration safeguard tests pass (4/4 in `renderOrchestrator.test.ts`) - [x] TypeScript compiles cleanly for engine and cli packages - [ ] CI pipeline |

fix(cli): reject directory --composition and add --browser-timeout (#1199) (#1200)
* fix(cli): reject directory --composition and add --browser-timeout (#1199) Two unrelated symptoms from issue #1199, fixed together: 1. `--composition .` (or any directory path) used to slip past the existsSync check in render.ts and explode downstream as `EISDIR: illegal operation on a directory, read` when the producer readFileSync'd the entry. The CLI now treats `.` / `""` as "omit the flag" (falls back to index.html) and rejects other directory paths with an actionable error pointing at the .html shape. 2. The 60s Puppeteer page.goto timeout in frameCapture.ts was hard- coded, so heavy compositions (many videos / fonts / asset requests) could not complete `domcontentloaded` in time. Add a configurable `pageNavigationTimeout` to EngineConfig (default 60_000, env fallback PRODUCER_PAGE_NAVIGATION_TIMEOUT_MS) and expose it as `--browser-timeout <seconds>` on `hyperframes render`. The flag threads through both renderLocal (via resolveConfig) and the docker bridge (via buildDockerRunArgs). Tests: - render.test.ts: forwards/omits pageNavigationTimeout into resolveConfig - dockerRunArgs.test.ts: forwards/omits --browser-timeout (seconds) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(cli): address PR #1200 review — extract validators, tighten bounds Addresses Vai's blockers and Miguel's nits on PR #1200: - Vai blocker 1 (fallow CRAP) + blocker 3 (no argv tests): Extract --browser-timeout and --composition validators into pure helpers in utils/renderArgs.ts with a structured-result discriminant. Drops ~45 lines of inline validation from run(), reducing its CRAP score 1290→978 and cyclomatic 75→65. 19 new unit tests cover the parse branches (sub-ms, overflow, NaN, Infinity, empty, negative, ".", "./", whitespace, directory, missing, ../escape, sibling-prefix). - Vai blocker 2 (sub-ms → timeout:0 = "no timeout"): reject inputs that round to <1 ms. Puppeteer treats page.goto({timeout:0}) as wait-forever, so --browser-timeout 0.0004 silently flipped the semantics. Now rejected with an explicit "rounds to 0 ms" error. - Vai important 5 (1e10 accepted → setTimeout overflow): cap at 86_400s (24h). Above Node's TIMEOUT_MAX ≈ 2^31-1 ms setTimeout fires immediately, the opposite of "long timeout." - Vai important 4 (related timeouts unmentioned): CLI help and docs now flag PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS and the 45s playerReadyTimeout as the other knobs heavy compositions may need. - Vai nit 7 (s/ms unit mismatch): help text and docs row both call out the SECONDS-vs-MILLISECONDS difference between flag and env. - Vai nit 8 / Miguel nit (composition flag discoverability): the --composition description now says "Pass `.` (or omit the flag) to render the project's index.html." - Miguel nit (dead branch): the entryFile === "" unreachable branch is gone. New helper uses `if (!trimmed || trimmed === ".")`. Also adds a trailing-separator guard on the project-containment check (sibling-prefix bypass: /proj-evil/x.html no longer slips past startsWith('/proj')) — flagged by the code review. The three remaining fallow complexity findings on render.ts (run, renderDocker, trackRenderMetrics) are inherited from main; this PR reduces run() but does not refactor it. Suppressed with fallow-ignore-next-line markers and inline rationale. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(cli): diverge --browser-timeout error messages per Vai nit 5 The `not-a-number` and `not-positive` branches in browserTimeoutErrorMessage shared the generic "Must be a positive number of seconds" message even though the discriminant carried distinct kinds. Diverge them so users see the specific failure mode: --browser-timeout abc → "Got \"abc\", which is not a number." --browser-timeout -5 → "Got \"-5\" seconds, which is not positive." The shared hint ("pass a positive number of seconds, e.g. 180") is preserved on both branches.

fix(engine): use totalmem() instead of freemem() for memory scaling
Addresses review feedback: freemem() is misleading on macOS where aggressive file caching reports low free memory even on high-spec machines. Switched to totalmem()-based thresholds consistent with calculateOptimalWorkers in parallelCoordinator.ts. Thresholds now based on total RAM: - <4GB total: GPU=512MB, V8=256MB, cache=32/128MB - <8GB total: GPU=1024MB, V8=512MB, cache=64/256MB - >=8GB total: unchanged (4096MB GPU, no V8 cap, 256/1500MB cache) |

fix(engine): scale Chrome memory budget and frame cache to available RAM
On low-memory systems (<4GB free), Chrome's --force-gpu-mem-available-mb=4096
causes the renderer to allocate more GPU texture memory than the system can
provide, leading to OOM crashes during frame capture ("Target closed").
Changes:
- Scale --force-gpu-mem-available-mb to match available system RAM
(512MB when <2GB free, 1024MB when <4GB, 4096MB otherwise)
- Add --js-flags=--max-old-space-size=N on low-memory systems to cap
Chrome's V8 heap (256MB when <2GB free, 512MB when <4GB)
- Scale frame data URI cache defaults: 32 entries/128MB when <2GB free,
64 entries/256MB when <4GB, unchanged otherwise

fix(engine): treat ffmpegStreamingTimeout as per-frame inactivity, not total render time (#901)
## Summary - Convert `streamingEncoder.ts`'s safety timer from a total-render hard cap to a per-frame inactivity timeout - Reset the timer only on `accepted === true` writes — buffered writes don't count as consumer progress - Update the `ffmpegStreamingTimeout` config doc to reflect the new semantics ## The bug The timer was set once at spawn and fired SIGTERM unconditionally at `ffmpegStreamingTimeout` ms — turning a "FFmpeg is hung" guard into a hard cap on total render duration. Slow-but-progressing captures (CI runner under load, large compositions, slower compositor paths after [#838](https://github.com/heygen-com/hyperframes/pull/838)'s always-clip change) regularly exceeded the 600s default and were killed mid-encode. The symptom surfaced as: ``` Streaming encode failed: FFmpeg exited with code 255 video:NNNkB audio:0kB ... [libx264 @ ...] frame I:3 Avg QP:12.91 size: 73263 [libx264 @ ...] frame P:431 Avg QP:14.72 size: 31633 ... [libx264 @ ...] kb/s:7661.05 Exiting normally, received signal 15. ``` libx264 had encoded most frames cleanly; SIGTERM arrived during the encode, libx264 printed its end-of-encode stats, and Node observed a non-zero exit. The `audio:0kB` in stderr is incidental — `streamingEncoder` is video-only; audio is muxed later in `assembleStage`. Downstream reproduction: `style-13-prod` fails deterministically in `heygen-com/hyperframes-internal` CI after bumping `@hyperframes/producer` from 0.6.7 → 0.6.10. Bisects to #838 widening the SDR capture path at dpr=1 — same composition shape, slower per-frame, total render now crosses 600s. ## The fix Convert the timer to a heartbeat: each `writeFrame` that goes through to the kernel pipe (i.e. `stdin.write` returns `true`) resets it. Only true hangs (no successful frame write for the timeout window) trip SIGTERM now; "slow but progressing" renders are unbounded. Crucially, the heartbeat does **not** reset on `accepted === false`. A `false` return means Node had to buffer the write because FFmpeg hasn't drained the pipe yet — that's not proof of consumer progress, just proof we produced. Without this distinction, a hung FFmpeg with a live Chrome would queue frames into Node's writable buffer indefinitely (no backpressure path back to the capture loop) and grow until OOM. In steady state with a slow-but-alive FFmpeg, writes alternate between `true` and `false` as the buffer drains and refills; the `true`s are enough to keep the heartbeat ticking. Renames are intentionally avoided — `ffmpegStreamingTimeout` keeps its name and `600_000` default; only the semantics changed. The config doc spells out the new behavior so downstream consumers know what 600s now means. ## Test plan - [x] **Slow-but-progressing capture** (`accepted=true`): 9× `writeFrame` at 900ms intervals (under the 1000ms threshold) — encoder stays alive through 8.1s. Stall past the threshold — SIGTERM fires. - [x] **Stalled FFmpeg with live producer** (`accepted=false`): override `stdin.write` to return false; pump 9× `writeFrame` at 900ms intervals. SIGTERM still fires inside the 1000ms window — buffered writes don't keep the heartbeat alive. - [x] Existing 33 tests in `streamingEncoder.test.ts` still pass - [x] Lint (`oxlint`) + format (`oxfmt --check`) clean - [ ] CI regression suite 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(engine): enable browser pool and deduplicate concurrent Chrome launches (#889)
## Summary
- **Enable browser pool by default** (`enableBrowserPool: true`) — parallel capture workers now share a single Chrome process via reference-counted pool instead of each spawning their own (~256MB each). A 6-worker render drops from 7+ browser parent processes to 1 shared pool.
- **Add launch-promise deduplication** in `acquireBrowser` — when multiple workers race into the pool simultaneously (via `Promise.all`), they await the same launch Promise instead of each triggering a separate Chrome spawn. Same pattern as the existing `_autoBrowserGpuModeCache` for GPU probes.
- **Add `connected` health check** on pool hit — if Chrome crashes mid-render, subsequent acquires detect the dead browser and launch fresh instead of returning a stale reference.
- **Add `drainBrowserPool()`** for explicit cleanup between independent render jobs.
- **CLI studio server** now uses the shared pool instead of its own redundant `enableBrowserPool: false` singleton, so thumbnail generation shares Chrome with render workers.
## Problem
The engine had a reference-counted browser pool (`browserManager.ts:73-75`) but it was **disabled by default** (`enableBrowserPool: false`). This meant:
1. **Every parallel worker spawned its own Chrome** — a `--workers 6` render launched 7+ independent Chrome processes (1 probe + 6 workers), each ~256MB.
2. **The pool had a race condition** — even if manually enabled, concurrent workers calling `acquireBrowser()` via `Promise.all` could all see `pooledBrowser === null` before the first launch completed, spawning N Chromes instead of 1.
3. **No crash recovery** — if Chrome died, the pool still held the dead reference. Subsequent acquires got a disconnected browser.
4. **CLI studio server ran its own singleton** — `studioServer.ts` explicitly set `enableBrowserPool: false` and managed a separate browser, so thumbnails and renders could never share.
Over time, orphaned Chrome processes accumulated across renders and previews. We observed **344 headless Chrome processes** consuming **569% CPU and 20% memory** on a dev machine.
## Before / After (6-worker parallel render)
| Metric | Before (pool off) | After (pool on) |
|--------|-------------------|-----------------|
| Browser parent processes | 7+ (1 probe + 6 workers) | **2** (1 GPU probe + 1 shared) |
| Total Chrome processes (with helpers) | 40-50+ | **14** |
| Memory during capture | ~20%+ | **4.6%** |
| Render time (1200 frames, 30fps) | ~64s | **53s** (~17% faster) |
| Post-render orphans | Accumulated over time | **0** |
## Changes
| File | Change |
|------|--------|
| `engine/src/config.ts` | `enableBrowserPool` default `false` → `true` |
| `engine/src/services/browserManager.ts` | Extract `launchBrowser()`, add `_pooledBrowserLaunchPromise` dedup, add `connected` check on pool hit, add `drainBrowserPool()` and `_resetBrowserPoolForTests()` |
| `engine/src/index.ts` | Export `drainBrowserPool` |
| `engine/src/services/browserManager.test.ts` | Pool dedup and drain tests |
| `cli/src/server/studioServer.ts` | Remove `enableBrowserPool: false` override — thumbnails now share the pool |
| `producer/src/services/browserManager.ts` | Re-export `drainBrowserPool` |
## Backward compatibility
- `PRODUCER_ENABLE_BROWSER_POOL=false` env var disables pooling (same as before).
- Callers passing `{ enableBrowserPool: false }` explicitly still get isolated browsers.
- Tests that set `enableBrowserPool: false` in their config fixtures continue to work.
## Test plan
- [x] Engine tests pass (597/597)
- [x] Producer tests pass (406/407, 1 pre-existing flaky test in `pngDecodeBlitWorkerPool`)
- [x] Build passes (lint, format, typecheck all green via lefthook pre-commit)
- [x] Manual render: `shortform-financial` with `--workers 6` → 1200 frames in 53s, 0 orphaned Chrome processes after completion
- [x] Process monitoring during render confirmed 2 browser parents (1 GPU probe + 1 shared pool) instead of 7+

perf(engine): faster shader transitions via page-side WebGL compositing (#832)
* fix(cli): prefer puppeteer cache + numeric version sort (staff review) Two correctness fixes from PR #821 self-review: 1. Cache priority order. Previous order was hyperframes-managed cache → puppeteer cache. HF cache is pinned to CHROME_VERSION (131-era) which lags 17+ releases behind upstream; if a user separately installed a newer chrome-headless-shell via @puppeteer/browsers install, the CLI would silently hand engine the older HF-cache binary while engine's own resolveHeadlessShellPath would have picked the newer one. Flip the priority so puppeteer cache wins, matching engine semantics. 2. Numeric (not lexicographic) version sort. `readdirSync.sort().reverse()` over names like `linux-148.0.7778.97` and `linux-99.0.6533.123` would return `linux-99...` first because character '9' outranks '1'. Parse each name into integer segments and compare them numerically. Tests: add both-caches-populated and linux-148-beats-linux-99 cases. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * perf(engine): page-side compositing for shader transitions (opt-in spike) Add an opt-in `--page-side-compositing` flag (CLI) backed by a new engine config field `enablePageSideCompositing` and env var `HF_PAGE_SIDE_COMPOSITING`. When set, SDR shader-transition compositions skip the Node-side layered blend (the hf#677 chain) and instead run the shader inside Chrome via a page-side WebGL canvas; the engine then captures ONE opaque RGB frame per output frame via the existing streaming capture path. This is the strongest non-beginFrame perf lever for Mac users, who cannot take the beginFrame `~5×` path (Chromium structural limit, crbug.com/40656275). Stacks on top of the hf#677 1.95× baseline. Default OFF — existing fixture pins (byte-exact MP4 output) are preserved. Opt-in path is intentionally PSNR-pinned, not byte-equal (WebGL is f32; Node is f64). HDR content forces the existing layered path regardless. Implementation: - engine: new `EngineConfig.enablePageSideCompositing` (default false). - producer/fileServer: new `HF_PAGE_SIDE_COMPOSITING_STUB` early-page script injected into the served HTML head when the flag is on. - producer/renderOrchestrator: when the flag + no HDR + no png-sequence, route SDR transitions through the streaming path instead of the layered HDR stage. - shader-transitions: new `engineModePageComposite.ts` installs a fullscreen WebGL compositor overlay and wraps `window.__hf.seek` so each seek inside a transition window captures both scenes via the Chromium `drawElementImage` API to GL textures, runs the fragment shader, and displays the composited result on the overlay canvas. The engine takes one screenshot per frame and sees the composited overlay. - cli: new `--page-side-compositing` flag sets `HF_PAGE_SIDE_COMPOSITING=true` before producer load. - scripts/page-side-compositing-smoke: bundled-CLI smoke that renders a representative fixture with and without the flag, validates the canary strings are in the shipped bundles, and writes a wall-time pair. Determinism trade documented in the engine config doc-comment. The smoke script enforces the bundled-CLI validation discipline from prior perf work (see internal feedback note `validate_bundled_cli_not_dev_path`). Runtime requirement: Chromium's `CanvasDrawElement` feature (already enabled by the engine's `--enable-features=CanvasDrawElement` launch flag). When the runtime feature is unavailable, the page-side installer logs a warning and falls back to opacity-flip mode — the engine still takes the streaming path; the transition window degrades to a hard scene swap. Vance will validate on Mac Chrome where the feature is supported. Co-Authored-By: Vai <vai@heygen.com> * fix(shader-transitions): use html2canvas for page-side compositor capture The original drawElementImage approach fails in engine render mode because the virtual-time shim prevents Chromium from generating paint records for cloned elements. drawElementImage requires a cached paint record from the browser's compositor — clones created at capture time never receive one because (a) shimmed rAFs deadlock inside the seek wrapper, (b) original rAFs don't produce real paints under virtual-time control, and (c) layoutsubtree canvases don't apply CSS stylesheet rules to children. Switch scene capture to html2canvas (foreignObjectRendering: false), the same JS-based renderer already used by the preview-mode fallback path in capture.ts. html2canvas reads computed styles and renders via its own canvas drawing pipeline with no dependency on the browser paint cycle. Also fixes: - Engine seek must return the result so Puppeteer awaits async seek promises (frameCapture.ts). - GSAP opacity cache: compositor must restore scene opacity before seek, not after — GSAP caches inline values and skips re-writes. - Support check gates on WebGL availability, not drawElementImage.

Docker mode silently dropped --page-side-compositing — thread pageSideCompositing through DockerRenderOptions/buildDockerRunArgs with regression tests. 3. Fragmented gating across 4 independent sites could disagree: - Stub injection gated only on cfg flag (leaked into HDR/alpha) - Probe-created fileServer never got the stub - needsAlpha (WebM/MOV) not excluded from the gate - WebGL-unavailable fallback claimed layered path would run but orchestrator had already disabled it Fix: compute stub injection at the same site as the layered-bypass decision (after hasHdrContent is known), using addPreHeadScript on the already-running fileServer. Single predicate now gates both decisions, including !needsAlpha. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * perf(engine): two-phase drawElementImage capture for page-side compositing Replace html2canvas with native drawElementImage for scene capture in the page-side compositor. drawElementImage reads from the browser's own paint cache, giving pixel-identical output to the preview path. The blocker was that cloned elements inside layoutsubtree canvases have no cached paint record under virtual time — the compositor only paints when explicitly triggered. Fix: split the seek+composite into two phases with an engine-forced paint between them. Phase 1 (seek wrapper, page-side): - GSAP seek positions the timeline - Clone FROM/TO scenes into visible layoutsubtree staging canvases - Set window.__hf_page_composite_pending flag Engine paint force (frameCapture.ts): - Detect pending flag after seek returns - Fire micro Page.captureScreenshot (1x1 clip) via CDP to force the browser compositor to paint all visible elements including staging canvas children Phase 2 (page.evaluate, page-side): - drawElementImage reads the now-valid paint records - Upload textures to WebGL, run shader, show GL overlay Key insight: staging canvases must be visible (not opacity:0) for the browser to paint their children. They sit at z-index:-9998, behind the main DOM and covered by the GL overlay during transitions.

Changes: - Engine config: enablePageSideCompositing defaults to true - CLI: flag default flipped to true; --no-page-side-compositing disables - Orchestrator: added composition.videos.length === 0 gate - Docker: forwards --no-page-side-compositing when explicitly disabled - Config tests updated for new default Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(engine): support video elements on page-side compositing fast path Three-phase capture protocol lets shader transitions render video scenes without falling back to the slow Node-side layered pipeline: 1. Seek → compositor records transition metadata, sets pending flag 2. onBeforeCapture → video frame injector updates <img> replacements 3. prepare → cloneNode picks up current video frames, img.decode() awaits 4. micro-screenshot → forces browser to paint cloned elements 5. resolve → drawElementImage reads paint records, shader composites Key changes: - Remove `composition.videos.length === 0` gate from orchestrator - Split compositor resolve into prepare (clone) + resolve (shader) - Move onBeforeCapture before compositor prepare in frameCapture.ts - Await img.decode() on cloned data-URI images to prevent stale frames - Stop manipulating scene opacity in compositor (GL canvas overlay suffices) - Add gsap.set declaration for shader-transitions ambient types - Add video_missing_timing_attrs lint rule for <video> without id/data-start/data-end Performance: compositions with video now render at 7.5s (6 workers) instead of 2m38s on the layered path.

Videos "just work" without requiring authors to add data-start, data-end, or id attributes.

feat(engine): browserGpuMode "auto" — probe WebGL once, fall back to software
When the host doesn't have a usable GPU (CI containers, eval rigs without
GPU passthrough, dev VMs), Chrome's hardware-mode WebGL flags
(`--use-gl=egl/metal/d3d11`) silently leave WebGL unavailable —
`getContext("webgl")` returns null, three.js' WebGLRenderer dies, the
canvas stays black. Surfaced today by Abhay's c2v-eval failing on a
docker render of an hf bundle that uses three.js + a custom fragment
shader.
The fix that's been there: `--use-gl=angle --use-angle=swiftshader` (CPU
software WebGL, ~5-50× slower but pixel-identical). The engine already
exposed `browserGpuMode: "software"` for this. The gap was discovery —
users had to know to pass `--no-browser-gpu` on no-GPU hosts.
This change adds `browserGpuMode: "auto"` (now the CLI default for local
renders): on first launch in the process, probe Chrome with hardware
args, check `canvas.getContext("webgl") !== null`, cache the result.
~1-2 s on first render, free on every subsequent render in the same
worker. Hardware GPUs keep their fast path; no-GPU hosts get SwiftShader
without ceremony.
Behaviour matrix:
- No flag, no env, local → "auto" (NEW default)
- `--browser-gpu` → "hardware" (force; errors if no GPU)
- `--no-browser-gpu` → "software" (force SwiftShader)
- `PRODUCER_BROWSER_GPU_MODE` → "hardware" / "software" / "auto" / unset
- Docker mode → forced "software" (unchanged)
Engine-config default stays "software" (conservative for embedders); the
"auto" default lives in the CLI's `resolveBrowserGpuForCli` so producer
embedders aren't surprised by a probe-on-launch.
Also adds `--enable-unsafe-swiftshader` to the software flag set —
Chrome 120+ deprecated implicit SwiftShader fallback and emits a
deprecation warning unless the flag is set explicitly. Despite the
"unsafe" name this is exactly the pre-deprecation behaviour; the rename
is about Chrome's threat model on the open web, not about the rendering
itself.
Verification:
- Engine 535/535 + CLI 256/256 (incl. new probe tests + tri-state CLI test)
- Empirical: probe on this no-GPU devbox returns "software" in 240 ms,
cached 0 ms on subsequent calls
- Format / lint / typecheck clean across all packages

feat: add browser GPU render mode (#571)
## Problem HyperFrames already had `--gpu`, but that flag only controlled FFmpeg hardware encoding. The browser capture path still forced Chrome/WebGL through SwiftShader software GL via `--use-angle=swiftshader`, so WebGL-heavy local renders could leave the biggest bottleneck on the CPU path. That made the existing flag naming easy to misread: `--gpu` sounded like it accelerated the whole render, but it did not change the browser frame-capture backend. ## What this fixes - Enables host browser GPU acceleration automatically for local CLI renders. - Adds `--no-browser-gpu` as the local opt-out for software Chrome/WebGL capture. - Keeps `--browser-gpu` as an explicit local browser-GPU request. - Adds `browserGpuMode: "software" | "hardware"` to engine config, with `PRODUCER_BROWSER_GPU_MODE` env support for lower-level producer users. - Keeps Docker browser capture on the deterministic software path. - Maps hardware browser GPU mode to platform-native Chrome backends: - macOS: Metal-backed ANGLE - Windows: D3D11-backed ANGLE - Linux: EGL - Blocks explicit `--browser-gpu --docker` with a clear error because Docker browser GPU passthrough is not cross-platform. - Clarifies docs so `--gpu` means FFmpeg encoder GPU and browser GPU means Chrome/WebGL capture GPU. - Keeps encoder backend selection auto-detected from FFmpeg capabilities: - NVIDIA: NVENC - macOS: VideoToolbox - Linux: VAAPI - Intel: QSV ## Why two flags There are two separate GPU surfaces in the render pipeline: 1. Browser GPU controls Chrome frame capture. - Affects WebGL, canvas, CSS rendering, compositing, and screenshot capture inside the browser. - This is enabled automatically for local CLI renders. - Use `--no-browser-gpu` when you want the software browser baseline. 2. `--gpu` controls FFmpeg video encoding. - Affects the final encode step after frames have already been captured. - The concrete encoder is auto-detected from the host FFmpeg build and hardware. - It can be faster for some machines/codecs, but it is not equivalent to browser rendering acceleration. The controls stay independent because users may want: - `hyperframes render` for the fast local default with browser GPU capture. - `hyperframes render --no-browser-gpu` for the software-browser local baseline. - `hyperframes render --gpu` for browser GPU capture plus hardware FFmpeg encoding. - `hyperframes render --no-browser-gpu --gpu` for software browser capture plus hardware FFmpeg encoding. - `hyperframes render --docker` for deterministic browser capture. ## Why `--gpu` does not imply browser GPU Keeping `--gpu` scoped to FFmpeg encoding avoids a semantic break and keeps the risk profile explicit: - `--gpu` already means encoder acceleration. Expanding it to also change Chrome capture would silently alter behavior for users who only wanted hardware encoding. - Browser GPU and encoder GPU have different portability. Encoder GPU can work in Docker when the host exposes the right devices; browser GPU passthrough is not cross-platform, so this PR intentionally blocks explicit `--browser-gpu --docker`. - The Apple presentation benchmark shows why the controls should stay separate: browser GPU capture was the useful improvement, while macOS VideoToolbox via `--gpu` was slower and produced larger output for this `standard` H.264 run. If HyperFrames later wants a single umbrella acceleration control, it should be explicit, for example `--acceleration browser|encoder|all` or `--gpu=browser|encoder|all`, rather than changing the meaning of the existing boolean `--gpu`. ## Root cause `buildChromeArgs()` always injected `--use-gl=angle --use-angle=swiftshader`. `disableGpu` only appended `--disable-gpu`; it did not provide a hardware-GPU mode. That made the public `--gpu` flag look broader than it was, because render capture stayed software-backed even when encoder GPU was requested. ## Verification ### Local checks - `bun install` - `bun run build:hyperframes-runtime` - `bun run --filter @hyperframes/engine test src/config.test.ts src/services/browserManager.test.ts` - `bun run --filter @hyperframes/cli test src/utils/dockerRunArgs.test.ts src/commands/render.test.ts` - `bun run --filter @hyperframes/cli typecheck` - `bun run --filter @hyperframes/engine typecheck` - `bun run --filter @hyperframes/producer typecheck` - `cd packages/producer && bunx vitest run src/services/renderOrchestrator.test.ts` - `bunx oxlint packages/cli/src/commands/render.ts packages/cli/src/commands/render.test.ts packages/cli/src/utils/dockerRunArgs.ts packages/cli/src/utils/dockerRunArgs.test.ts packages/engine/src/config.ts packages/engine/src/config.test.ts packages/engine/src/services/browserManager.ts packages/engine/src/services/browserManager.test.ts packages/producer/src/services/renderOrchestrator.test.ts` - `bunx oxfmt --check ...` on changed source/docs files - `git diff --check` - `bun packages/cli/src/cli.ts render --help | rg -n "browser-gpu|no-browser-gpu|GPU"` - `bun packages/cli/src/cli.ts render packages/producer/tests/css-spinner-render-compat/src --output /tmp/hf-auto-browser-gpu-smoke.mp4 --workers 1 --quality draft --fps 24 --strict` - Render plan prints `GPU: browser GPU (auto)`. - `bun packages/cli/src/cli.ts render packages/producer/tests/css-spinner-render-compat/src --no-browser-gpu --output /tmp/hf-software-browser-gpu-smoke.mp4 --workers 1 --quality draft --fps 24 --strict` - Render plan does not print browser GPU. - `bun packages/cli/src/cli.ts render packages/producer/tests/css-spinner-render-compat/src --docker --browser-gpu --output /tmp/should-not-render.mp4` - Exits 1 with `Browser GPU is local-only`. - `buildDockerRunArgs()` regression coverage asserts Docker container args include `--no-browser-gpu`, preventing nested container renders from re-enabling browser GPU through the local CLI default. - `resolveBrowserGpuForCli()` regression coverage asserts `PRODUCER_BROWSER_GPU_MODE=software` opts out when no CLI browser-GPU flag is supplied, while explicit `--browser-gpu` / `--no-browser-gpu` still win. - `ffmpeg -v error -i /tmp/hf-auto-browser-gpu-smoke.mp4 -f null -` - `ffmpeg -v error -i /tmp/hf-software-browser-gpu-smoke.mp4 -f null -` - `ffprobe -v error -show_entries format=duration:stream=codec_name,width,height,r_frame_rate -of json /tmp/hf-browser-gpu-smoke.mp4` -> H.264, 1920x1080, 24fps, 5.0s ### Apple presentation benchmark Rendered `/Users/miguel07code/Downloads/apple-presentation.zip` as supplied after extracting to `/tmp/hf-apple-profile/apple-presentation`. Fixed settings: - 1920x1080 - 30fps - `standard` quality - 4240 frames - 141.32s duration - 8-worker cap; render auto-calibration used 6 capture workers - macOS host detected FFmpeg GPU encoder: `videotoolbox` | Mode | Equivalent flags after this PR | Wall time | vs software-browser baseline | Speed | Capture | Encode | Output | | --- | --- | ---: | ---: | ---: | ---: | ---: | ---: | | Software browser + CPU encode | `--no-browser-gpu` | 120.77s | baseline | 1.17x | 97.87s | 10.04s | 8.38MB | | Browser GPU + CPU encode | default local render | 70.10s | 42.0% faster | 2.02x | 50.72s | 9.91s | 8.39MB | | Software browser + encoder GPU | `--no-browser-gpu --gpu` | 133.16s | 10.3% slower | 1.06x | 103.58s | 18.31s | 25.43MB | | Browser GPU + encoder GPU | `--gpu` | 74.12s | 38.6% faster | 1.91x | 46.69s | 17.93s | 25.45MB | Result: browser GPU capture is the meaningful improvement for this WebGL/browser-capture-heavy presentation. VideoToolbox encoding was slower and produced larger files for this current `standard` H.264 path, so `--gpu` should stay separate and opt-in. Why `--gpu` plus browser GPU was slower than browser GPU alone: the combined run captured about 4.0s faster than browser GPU alone, but VideoToolbox encoding was about 8.0s slower than CPU x264 encoding, so the encode loss outweighed the capture gain. ### VideoToolbox flag check I also isolated the encode stage against the already-captured Apple frames to check whether macOS GPU encoding only needed special flags. `ffmpeg -h encoder=h264_videotoolbox` does not expose a CRF/CQ-style quality option like x264. It exposes bitrate-oriented and VideoToolbox-specific options such as `-b:v`, `-realtime`, `-profile`, `-coder`, `-prio_speed`, `-power_efficient`, and `-allow_sw`. That means our current `-q:v` mapping is not equivalent to x264 CRF and can produce very different bitrate/size behavior. Measured full-frame encode variants on this host: | VideoToolbox variant | Encode wall time | Output size | Bitrate | | --- | ---: | ---: | ---: | | Current `-q:v 64 -allow_sw 1` | 18.76s | 25.31MB | 1.43 Mbps | | Current without `-allow_sw 1` | 18.21s | 25.31MB | 1.43 Mbps | | `-b:v 500k -maxrate 750k -bufsize 1000k -profile high -coder cabac -realtime 1 -prio_speed 1 -power_efficient 0` | 20.58s | 7.42MB | 0.42 Mbps | | Same with `-b:v 1500k` | 20.84s | 16.70MB | 0.95 Mbps | | `-b:v 500k -profile baseline -coder cavlc -realtime 1 -prio_speed 1 -power_efficient 0` | 18.11s | 8.94MB | 0.51 Mbps | Conclusion: VideoToolbox can be made size/bitrate-predictable with explicit `--video-bitrate`, but the tested speed-oriented flags did not make it faster than CPU x264 wall time for this render. That reinforces keeping `--gpu` encoder acceleration explicit and separate from browser GPU capture. Artifacts from the local benchmark: - `/tmp/hf-apple-profile/results/cpu.mp4` - `/tmp/hf-apple-profile/results/browser-gpu.mp4` - `/tmp/hf-apple-profile/results/encoder-gpu.mp4` - `/tmp/hf-apple-profile/results/full-gpu.mp4` - `/tmp/hf-apple-profile/results/summary.json` All four benchmark MP4s completed `ffprobe` and full `ffmpeg -f null` decode checks. ### Pixel comparison Compared decoded MP4 output between software-browser and browser-GPU renders: - Apple presentation: - 4240 frames compared - 636 exact matching decoded frame hashes - 3604 different decoded frame hashes - Average PSNR: 57.79 dB - `css-spinner-render-compat` clean fixture: - 120 frames compared - 0 exact matching decoded frame hashes - Average PSNR: 61.57 dB Interpretation: browser GPU output is not strict hash/pixel-identical to the software-browser path after lossy H.264 encode, but the measured deltas are visually tiny. Above 50 dB PSNR is typically visually indistinguishable for normal video review. Use `--no-browser-gpu` or Docker when strict cross-run/cross-machine reproducibility matters more than local speed. ### Browser verification - Started HyperFrames Studio preview for `packages/producer/tests/css-spinner-render-compat/src`. - Used `agent-browser` to open `http://localhost:5191#project/src` and verify the composition loaded in Studio. - Screenshots: - `/tmp/hf-gpu-browser-proof/preview-loaded.png` - `/tmp/hf-gpu-browser-proof/preview-playing.png` - `/tmp/hf-gpu-browser-proof/preview-frame-60.png` - Agent-browser recordings: - `/tmp/hf-gpu-browser-proof/preview-playback.webm` - `/tmp/hf-gpu-browser-proof/preview-seek.webm` ## Notes - Browser GPU is enabled automatically for local CLI renders and disabled in Docker. - `--no-browser-gpu` is the opt-out for software Chrome/WebGL capture. - `--gpu` remains encoder-only and opt-in. - The Apple presentation zip has existing lint errors around unmanaged nested videos and imperative media `play()` calls. The benchmark still compares the same supplied source across modes, but it should not be treated as a clean deterministic-composition fixture. |

perf(engine): content-addressed extraction cache for video frames (#446)
## What Adds a content-addressed cache for extracted video frames, keyed on the tuple `(path, mtime, size, mediaStart, duration, fps, format)`. Repeat renders of the same composition (studio edit → re-render, preview → final) skip the ffmpeg extraction entirely. ## Why Video frame extraction is the dominant non-capture phase for video-heavy compositions. Studio iteration workflows extract the same frames over and over — each render burns ffmpeg time that adds no value. Validated on `/tmp/hf-fixtures/cfr-sdr-cache`: ``` Cold (miss): extractMs=69, videoExtractMs=70, totalElapsedMs=2052 Warm (hit): extractMs=1, videoExtractMs=2, totalElapsedMs=1964 cacheHits: 0→1, cacheMisses: 1→0 ``` The fixture is tiny (3s CFR SDR @ 30fps), so the wall-clock delta is small; the extraction-time delta (69→1ms, 98%) scales linearly with source length. For heavy-iteration workflows (a user rendering the same composition while tuning encoding params), extraction time goes to zero on every repeat render. Depends on #444 (instrumentation surface) and #445 (segment-scope HDR preflight — otherwise cache keys would be unstable across renders on mixed-HDR compositions). ## How - New `packages/engine/src/services/extractionCache.ts`: - SHA-256 key over a stable JSON encoding of `(path, mtime_ms, size, mediaStart, duration, fps, format)`. Infinity duration is normalized to `-1` so unresolved natural-duration sources still produce stable keys. - Truncates to 16 hex chars in the entry directory name — 64 bits of entropy is plenty at cache scale and keeps `ls` output short. - `hfcache-v2-` schema prefix — bumping it invalidates old entries (callers own gc policy; the cache owns keys). - `.hf-complete` dotfile sentinel. An entry dir without the sentinel is treated as a miss (covers crash-mid-extract and abandoned writes); the next render re-extracts over the partial frames with `-y`. - `FRAME_FILENAME_PREFIX = "frame_"` shared with the extractor — future refactors only need to touch one place to rename frames. - `EngineConfig.extractCacheDir` (env: `HYPERFRAMES_EXTRACT_CACHE_DIR`) gates the feature. Undefined disables caching — extraction runs into the render's workDir and cleanup removes it on render end, preserving the prior behaviour exactly. No default root is chosen by the engine; the caller (CLI, app, studio) owns the location policy. - `ExtractedFrames.ownedByLookup` flag prevents `FrameLookupTable.cleanup` from rm'ing a shared cache dir at render end. Set to `true` on both hits and misses (misses own the directory they wrote into, but hand it over to the cache rather than deleting it). - Phase 3 extractor flow: 1. Snapshot `(videoPath, mediaStart, start, end)` per resolved video BEFORE Phase 2a/2b preflight mutates them — so cache keys are stable across renders that use workDir-local normalized files (those files have fresh mtimes every render). 2. Compute key, `lookupCacheEntry`. 3. On hit: rebuild `ExtractedFrames` from the cache dir plus the Phase 2-probed `VideoMetadata` — no re-ffprobe. 4. On miss: `ensureCacheEntryDir`, extract with `extractVideoFramesRange(..., outputDirOverride)`, then `markCacheEntryComplete` (the sentinel write is the last step so a crash leaves the dir un-sentineled). - `extractVideoFramesRange` gains an `outputDirOverride` parameter so cache-miss writes land directly in the keyed dir (no `join(outputDir, videoId)` wrapping). ## Test plan - [x] 19 unit tests in `extractionCache.test.ts` covering key determinism, mtime/size invalidation, format/fps/mediaStart/duration invalidation, Infinity normalization, sentinel semantics, missing-file tolerance - [x] 2 integration tests in `videoFrameExtractor.test.ts`: - "reuses extracted frames on a warm cache hit" — asserts `cacheHits=1`, `extractMs<50ms` on second call against a CFR SDR fixture - "invalidates the cache when fps changes" — different fps on second call forces a new miss - [x] End-to-end validation with `HYPERFRAMES_EXTRACT_CACHE_DIR` set, two runs of the same fixture - [x] Lint + format (oxlint + oxfmt) - [x] Typecheck (engine + producer) |

feat(engine): wire options.hdr through chunkEncoder + dynamic SDR→HDR transfer (#370)
## Summary
Three independent fixes that share a common thread: HDR config flowing correctly from `EngineConfig` down through every encoder. The headline fix: disk-based HDR encodes via `chunkEncoder` were silently producing BT.709-tagged output despite `options.hdr` being set.
## Why
`Chunk 3` of `plans/hdr-followups.md`. The streaming encoder was correct but `chunkEncoder.buildEncoderArgs` hard-coded BT.709 color tags and the `bt709` VUI block in `-x265-params`, even when callers passed an HDR `EncoderOptions`. Today this is harmless because `renderOrchestrator` routes native-HDR content to `streamingEncoder` and only feeds `chunkEncoder` sRGB Chrome screenshots — but the contract was a lie, and any future caller that wired HDR through `chunkEncoder` would silently get SDR output.
## What changed
**3A — `chunkEncoder` respects `options.hdr` (BT.2020 + mastering metadata).** When `options.hdr` is set, the libx265 software path emits `bt2020nc` plus the matching transfer (`smpte2084` for PQ, `arib-std-b67` for HLG) at the codec level *and* embeds master-display + max-cll SEI in `-x265-params` via `getHdrEncoderColorParams`. libx264 still tags BT.709 inside `-x264-params` (libx264 has no HDR support) but the codec-level color flags flip so the container describes pixels truthfully. GPU H.265 (nvenc/videotoolbox/qsv/vaapi) gets the BT.2020 tags but no `-x265-params` block, so static mastering metadata is omitted — acceptable for previews, not HDR-aware delivery.
**3B — `convertSdrToHdr` accepts a target transfer.** `videoFrameExtractor.convertSdrToHdr` was hard-coded to `transfer=arib-std-b67` (HLG) regardless of the surrounding composition's dominant transfer. `extractAllVideoFrames` now calls `analyzeCompositionHdr` first, then passes the dominant transfer (`"pq"` or `"hlg"`) into `convertSdrToHdr` so an SDR clip mixed into a PQ timeline gets converted with `smpte2084`, not `arib-std-b67`.
**3C — `EngineConfig.hdr` type matches its declared shape.** The IIFE for the `hdr` field returned `undefined` when `PRODUCER_HDR_TRANSFER` wasn't `"hlg"` or `"pq"`, but the field is typed as `{ transfer: HdrTransfer } | false`. Returning `false` matches the type and avoids a downstream `undefined` check.
## Test plan
- [x] `chunkEncoder.test.ts`: replaced the previous "HDR options ignored" assertions with 8 new specs covering BT.2020 + transfer tagging, master-display/max-cll embedding, libx264 fallback behavior, GPU H.265 + HDR (tags but no x265-params), and range conversion for both SDR and HDR CPU paths.
- [x] All 313 engine unit tests pass (5 new HDR specs).
- [x] `ffprobe` an HDR composition rendered through the chunk encoder path: shows `bt2020nc` color matrix, `smpte2084` transfer, and mastering display metadata.
## Stack
Chunk 3 of `plans/hdr-followups.md`. Independent of Chunks 1/4 (touches separate code paths).

fix: remove hidden audio gain in renders (#362)
## Summary
This fixes a render-time audio correctness bug where Hyperframes applied a hidden post-mix gain to every rendered output, boosting audio by about +2.6 dB and causing clipping on normally leveled sources.
It also fixes a related mute bug where `data-volume="0"` was treated as falsy and silently converted back to full volume during audio track preparation.
Additionally, this PR fixes the Studio workspace typecheck path for `@hyperframes/player`, so local pre-commit/typecheck flows no longer depend on the Player package having been built first.
## Root Cause
The issue report measured a near-constant gain increase and suspected a hidden normalization step. After tracing the engine audio path, the root cause turned out to be explicit code, not FFmpeg behavior:
- `packages/engine/src/config.ts` defaulted `audioGain` to `1.35`
- `packages/engine/src/services/audioMixer.ts` always appended a post-mix FFmpeg filter:
- `[mixed]volume=${masterOutputGain}[out]`
- with the default config, that meant every render got multiplied by `1.35`
That exactly matches the issue reporter's measured scalar boost.
While investigating the workaround, I also found a second correctness bug:
- `processCompositionAudio()` used `element.volume || 1.0`
- that coerced `0` to `1.0`
- so `data-volume="0"` did not actually mute the track in rendered output
Separately, the repo-level Studio typecheck could fail before any build step because:
- `packages/studio/src/player/components/Player.tsx` imports `@hyperframes/player`
- `packages/player/package.json` points TypeScript at built `dist/*` outputs
- in a fresh workspace, those built outputs may not exist yet
- Studio therefore failed type resolution for `@hyperframes/player` during pre-commit/typecheck
## What Changed
1. Set the engine default `audioGain` back to unity (`1`)
2. Preserve explicit zero volumes by changing `element.volume || 1.0` to `element.volume ?? 1.0`
3. Added regression coverage for both behaviors
4. Updated the producer-side config fixture to reflect the corrected default
5. Added a Studio tsconfig path mapping for `@hyperframes/player` to the local workspace source and widened `rootDir` so workspace typecheck succeeds without requiring a prior Player build
## Why These Changes Are Needed
This is not a UX preference issue; it is a correctness and API contract issue.
- The docs describe `data-volume` as a direct 0-1 control.
- Rendered output should preserve source levels unless the author explicitly changes them.
- Hidden global gain makes output non-deterministic from the author's perspective.
- `data-volume="0"` must mean silence, not full-volume playback.
- Local workspace typecheck should not require unrelated package build artifacts to exist first.
Leaving the current behavior in place means:
- voice recordings near normal peak levels can clip during render
- authors need undocumented manual compensation (`0.75`-ish scaling) to get unity output
- mute semantics in docs and code diverge
- local pre-commit/typecheck can fail for reasons unrelated to the actual diff being committed
## Testing
### Focused regression tests
Ran:
- `packages/engine/node_modules/.bin/vitest run packages/engine/src/config.test.ts packages/engine/src/services/audioMixer.test.ts`
Result:
- `10 passed`
These tests specifically verify:
- default resolved `audioGain` is `1`
- a track with `volume: 0` stays `volume=0` in the FFmpeg filter graph
- the post-mix output filter stays at unity gain (`[mixed]volume=1[out]`)
### Broader package verification
Ran:
- `bun run --filter @hyperframes/engine test`
- `bun run --filter @hyperframes/engine build`
- `packages/engine/node_modules/.bin/vitest run packages/producer/src/services/renderOrchestrator.test.ts`
- `bun run --filter @hyperframes/producer typecheck`
- `bun run --filter @hyperframes/studio typecheck`
- `bunx oxlint packages/engine/src/config.ts packages/engine/src/config.test.ts packages/engine/src/services/audioMixer.ts packages/engine/src/services/audioMixer.test.ts packages/producer/src/services/renderOrchestrator.test.ts`
- `bunx oxfmt packages/engine/src/config.ts packages/engine/src/config.test.ts packages/engine/src/services/audioMixer.ts packages/engine/src/services/audioMixer.test.ts packages/producer/src/services/renderOrchestrator.test.ts packages/studio/tsconfig.json`
- `bunx lefthook run pre-commit`
Results:
- full engine test suite passed (`309 passed`)
- engine build passed
- touched producer test file passed (`7 passed`)
- producer typecheck passed
- studio typecheck passed
- oxlint passed with `0 warnings, 0 errors`
- formatting passed
- pre-commit hook no longer hits the prior `@hyperframes/player` module-resolution blocker
## Known Verification Limitation
There is no meaningful browser UI flow for this bug: the defect is in the engine/CLI audio render pipeline rather than an interactive browser surface. Because of that, verification was done at the renderer and test level rather than through an agent-browser flow.
## User Impact
After this change:
- rendered audio matches source level by default
- authors no longer need to compensate for a hidden +2.6 dB boost
- `data-volume="0"` correctly mutes rendered audio
- the documented volume contract matches engine behavior again
- local workspace typecheck no longer depends on prebuilt `@hyperframes/player` artifacts
Closes #361.

feat(engine): add HDR video output pipeline (#265)
## Summary Adds the ability to render HDR video output (H.265 10-bit, BT.2020) from HyperFrames compositions. When the renderer detects HDR source video, it automatically switches to the HDR output pipeline — no flags needed. ## What it does - **Auto-detection** — Probes each video source with `ffprobe`. If any has bt2020/PQ/HLG color metadata, the output switches to H.265 10-bit with correct color tags. SDR-only compositions are unaffected (H.264, bt709). - **HLG pass-through** — Native HLG pixels from FFmpeg extraction are piped directly to the encoder without conversion. This avoids brightness loss from HLG→linear→PQ conversion (which requires an OOTF system gamma we can't reliably apply). - **Encoder HDR support** — Both chunk and streaming encoders accept HDR presets: `libx265`, `yuv420p10le`, BT.2020 color primaries, `hvc1` codec tag (required for Apple playback). - **WebGPU HDR capture (gated)** — A complete WebGPU float16 readback pipeline is implemented and tested but gated behind headed Chrome (headless doesn't expose WebGPU). Ready for future use with WebGPU canvas content. - **HDR utilities** — `detectTransfer()` (PQ vs HLG), `getHdrEncoderColorParams()`, `analyzeCompositionHdr()`. 15 unit tests. ## Key design decisions | Decision | Why | |----------|-----| | No `--hdr` flag | SDR content encoded as HDR causes orange shift in browsers. Auto-detect eliminates this. | | HLG pass-through (not HLG→PQ) | Conversion loses brightness without OOTF. Pass-through matches source exactly. | | `hvc1` codec tag | Apple QuickTime requires `hvc1` (not `hev1`) for HEVC playback. | | 1-hour streaming timeout | HDR capture at ~6fps needs more time than the default 10-minute FFmpeg timeout. | ## Files changed | File | What changed | |------|-------------| | `packages/engine/src/utils/hdr.ts` | **NEW** — HDR detection, transfer types, encoder params (15 tests) | | `packages/engine/src/services/hdrCapture.ts` | **NEW** — WebGPU readback, HLG conversion, PQ encode | | `packages/engine/src/services/streamingEncoder.ts` | HDR presets, raw rgb48le input, color tags | | `packages/engine/src/services/chunkEncoder.ts` | HDR presets, conditional color tags | | `packages/producer/src/services/renderOrchestrator.ts` | Auto-detection loop, HDR pass-through capture path | ## How to test Render a composition with an HDR video source. The output should be H.265 10-bit with HDR metadata visible in `ffprobe` (bt2020, arib-std-b67 or smpte2084). Plays correctly in QuickTime and on HDR displays. ## Stack position **2 of 6** — Stacked on #258 (SDR/HDR normalization). Provides the encoder infrastructure that phases 1-5 build on. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |
