Miguel Ángel 0f1c64dcae fix: address review feedback — observability, dedup, query-strip, catalog
Review items addressed:

1. Mirror video-failure warning in beginFrame path (was screenshot-only)
2. Fix resolveProjectRelativeSrc escape-fallback to use query-stripped
   cleanSrc instead of raw src for the normalize/strip arm
3. Export prepareFlattenedInnerRoot from @hyperframes/core/compiler and
   consume in the producer instead of duplicating the implementation
4. Use typed Window cast instead of (window as any) for __hfForceTimelineRebind
5. Regenerate docs/public/catalog-index.json with all 6 map blocks
6. Restore Maps nav group in docs.json (catalog generator had merged
   them into Data)

Miguel Ángel 8525bfdec9 fix(engine): strip query strings from video src when resolving on disk
resolveProjectRelativeSrc now strips query parameters (e.g. ?v=4)
before joining with the project directory. Browsers ignore query
strings when loading local files, but the filesystem resolver was
looking for the literal path including the query — causing video
extraction to silently skip the file and render frozen first frames.

JamesandClaude Opus 4.7 f4ecf96918 fix(engine,cli,producer): address PR #627 review feedback
- engine/chunkEncoder, engine/streamingEncoder: extend `-bf 0` to GPU h264
  paths (nvenc, qsv, vaapi) and `-b_strategy 0` for qsv so GPU-encoded
  outputs avoid negative-DTS freezes too — not just SW libx264.
- engine/videoFrameExtractor: detect mid-path traversal (e.g.
  `assets/../../foo.mp4`) by normalizing first and re-anchoring at the
  project root. Adds a regression test.
- engine/videoFrameExtractor: dedupe stderr "src not resolvable" warnings
  by `video.src` so a comp with N broken sources logs once, not N times.
- engine/videoFrameExtractor.test: drop dynamic `require("node:fs")`,
  use ES `import { writeFileSync } from "node:fs"`.
- engine/ffprobe: extract `readTagCI` helper for case-insensitive ffprobe
  tag reads (will recur for other libavformat-versioned sidecar tags).
- cli/background-removal/pipeline: collapse Quality / QUALITIES /
  QUALITY_CRF / DEFAULT_QUALITY / isQuality surface using
  `Quality = keyof typeof QUALITY_CRF`.
- producer/renderOrchestrator: replace `v.src.startsWith("/")` with
  `isAbsolute(v.src)` in the HDR probe path so Windows absolute paths
  (`C:\...`) aren't treated as relative — matches the audioMixer guard.

JamesandClaude Opus 4.7 39bc3749b4 fix(engine): default to codec-based alpha capability instead of relying on tags
Tag-based alpha detection (alpha_mode / ALPHA_MODE / pix_fmt yuva*) is
fundamentally brittle. Failure modes seen in the wild:
- case-sensitivity across ffmpeg versions (alpha_mode vs ALPHA_MODE)
- older muxers that omit the sidecar tag entirely
- mp4-as-webm rewraps that drop the tag
- ffprobe reporting yuv420p for VP9-with-alpha because the alpha plane
  lives in a Matroska BlockAdditional sidecar, not the main pix_fmt

Each of those silently strips alpha at extraction time. The bug doesn't
surface until the rendered output is missing layers — frustrating to debug,
silent in stdout. The previous case-insensitive fix patched one of the
failure modes; this commit removes the class.

The robust alternative is codec-based: any bitstream that CAN carry alpha
(VP9, VP8, ProRes 4444) gets the alpha-aware decoder and PNG output by
default, regardless of what the tag says. The cost is a small file-size
increase on opaque VP9/VP8 sources (cached PNGs vs JPGs); the benefit is
no class of silent alpha loss from tag misdetection.

- Adds codecMayHaveAlpha() + decoderForCodec() helpers and exports them.
- Updates extractVideoFramesRange to force libvpx-vp9 / libvpx for VP9 / VP8
  unconditionally (was: only when metadata.hasAlpha).
- Updates resolveFrameFormat to default to PNG for any alpha-capable codec
  (was: only when metadata.hasAlpha).
- +4 unit tests covering the codec table.

JamesandClaude Opus 4.7 2f96d5c7ab fix(engine,producer): URL-clamp sub-comp src paths and warn on silent extraction misses
A <video src='../assets/foo.mp4'> inside a sub-composition silently dropped
from extraction; the rendered output froze on the first decoded frame for
the entire clip, with no error in stdout.

Root cause: browser URL resolver clamps '..' at origin root (studio preview
loads fine), but path.join(projectDir, '../assets/foo.mp4') normalizes to
parent-of-project/assets/foo.mp4, which usually doesn't exist. existsSync
returns false, extraction is skipped, no frame lookup is built, the
per-frame injector has nothing to swap, and the <video> element's first
decoded frame paints every screenshot.

- Adds resolveProjectRelativeSrc in videoFrameExtractor that mirrors browser
  clamping (literal join first, then leading '..' stripped).
- Surfaces a loud stderr warning when the resolver misses.
- Mirrors fix in audioMixer.ts (same bug for <audio src='../'>) and
  renderOrchestrator HDR probe loop.
- +6 regression tests.

Miguel Ángel 31e8144304 fix: render parity for transparent looped videos (#478)
## Summary
- preserve alpha for render-injected video frames by detecting alpha streams with ffprobe and extracting alpha video frames as PNG
- keep `<video loop>` semantics through static parsing, compiler duration resolution, browser media discovery, and render frame lookup
- fail embedded preview startup before opening a broken browser page when the Studio bundle is missing
- align snapshot frame injection with looped media timing and VP9 alpha extraction

## Why
The Studio preview and rendered MP4 could disagree for timed transparent looped videos. The Comfy funding composition exposed two separate parity bugs: render-injected frames needed alpha-preserving PNG extraction, and the compiler was clamping a looped `data-duration="4"` video down to the 3.125s source duration. After the first source cycle, render lookup treated the video as inactive, hid the native video, and produced the blank polygon/glow the user saw around the rounded `0:03` mark.

`hyperframes lint` and `hyperframes validate` did not catch this because they check syntax/load/console/accessibility, not preview-vs-render visual parity. This PR adds regression coverage for the compiler loop-duration path and frame lookup path.

## Verification
- `bun run --filter @hyperframes/core test -- src/compiler/timingCompiler.test.ts src/compiler/htmlCompiler.test.ts`
- `bun test packages/producer/src/services/htmlCompiler.test.ts`
- `bun run --filter @hyperframes/engine test -- videoFrameExtractor ffprobe`

- `bun run lint`
- `bun run format:check ...` on touched files
- Comfy project: `node packages/cli/dist/cli.js validate` -> no console errors, 44 text elements pass WCAG AA
- Comfy project patched render from source: `/tmp/comfy-render-compare/fixed6-comfy.mp4`, 1920x1080, 30fps, 21.8s, 654 frames
- 3.00s-3.97s render contact sheet: `/tmp/comfy-render-compare/fixed6-window-contact.png`
- targeted fixed render capture at 3.733s: `/tmp/comfy-render-compare/probe-capture-fixed/captured/frame_000112.jpg`
- agent-browser Studio proof screenshot at 3.7s: `/tmp/comfy-render-compare/agent-browser-studio-3_7-fixed.png`
- agent-browser-driven recording of 3s seek pass: `/tmp/comfy-render-compare/agent-browser-wysiwyg-3s-fixed.webm`

Note: `bun run --filter @hyperframes/cli dev -- validate` is blocked in source mode by the existing `contrast-audit.browser.js` default-export loader issue; packaged `node packages/cli/dist/cli.js validate` passes for this project.

Miguel Ángel 267ffd3fca fix(engine,producer): preserve template-wrapped sub-composition media offsets (#476)
## Problem

Template-wrapped sub-compositions could still lose correct parent timing during render in more than one place.

In the validated repros, a host sub-composition starting after the intro (and in one follow-up repro, starting at `20s` after earlier compositions) contained scene-local media inside it. On the broken paths:

- template-wrapped media could be missed during compile and scheduled at raw scene-local time
- already-correct first-pass offsets could be clobbered during `recompileWithResolutions()`
- even after those two fixes, the browser-metadata reconcile step in `executeRenderJob()` could still overwrite a compiled global `end` with a scene-local `data-end` from the inlined DOM, clipping the tail off late-start sub-composition media

## What this fixes

### Template-wrapped media discovery

- `parseVideoElements`, `parseImageElements`, and `parseAudioElements` now unwrap a single top-level `<template>` wrapper before scraping media
- the unwrap helper is DOM-based, not regex-based, so it avoids the CodeQL backtracking warning and only unwraps the exact single-wrapper shape we want
- multiple sibling templates or other top-level content are left untouched instead of being rewritten heuristically

### Offset preservation after duration resolution

- `recompileWithResolutions()` now preserves the first-pass sub-composition media arrays when the already-inlined HTML no longer contains `[data-composition-src]` hosts
- that prevents correctly offset media metadata from being overwritten by scene-local media parsed from the merged DOM

### Browser metadata reconciliation in the compiled time origin

- browser-discovered media can still report scene-local `data-start` / `data-end` from the merged DOM after inlining
- the producer now reprojects browser `end` values into the compiled element's time origin before reconciling them back into `composition.videos` / `composition.audios`
- this prevents late-start sub-composition media from getting truncated back to a scene-local end during the probe phase

### Regression coverage

- adds focused engine tests for the template unwrap helper
- adds producer regression coverage for both the initial compile path and the post-inline `recompileWithResolutions()` path
- adds producer regression coverage for late-start host compositions (`t≈20`) with scene-local media inside them
- adds producer unit coverage for the browser-end reprojection helper used by the reconcile path

## Root cause

There were three distinct renderer failures behind the bug:

### 1. Template contents were invisible to the media scrapers

`parseSubCompositions()` reads raw sub-composition HTML and applies the host offset to discovered media. But the engine media helpers were querying the parsed document directly, and linkedom follows browser semantics here: top-level `<template>` contents live in a `DocumentFragment`, so `querySelectorAll()` never saw those `<video>` / `<audio>` / `<img>` nodes.

That meant template-wrapped sub-compositions could silently produce zero discovered media during the first pass.

### 2. The duration-resolution recompile could clobber already-correct offsets

After the browser resolves composition durations, `recompileWithResolutions()` reparses the already-inlined HTML. By that point the original `[data-composition-src]` hosts are gone, so `parseSubCompositions()` legitimately returns no nested media.

The old code still rebuilt the deduped media arrays from the merged DOM, which let scene-local media parsed from the inlined HTML overwrite the correctly offset first-pass metadata.

### 3. The browser probe reconcile path mixed two timing coordinate systems

`discoverMediaFromBrowser()` reads `data-start` / `data-end` directly from the live DOM after sub-compositions are already inlined. For nested media, those attributes can still be scene-local even though the compiled metadata has already been offset into the parent host timeline.

The old reconcile path compared those values directly and overwrote `existing.end` whenever the numbers differed. For a late-start sub-composition, that could replace a correct global end like `25.5` with a scene-local end like `5.5`, cutting the clip off during render.

## Verification

### Local checks

- `bun test packages/engine/src/utils/htmlTemplate.test.ts`
- `bun test packages/producer/src/services/htmlCompiler.test.ts`
- `bunx vitest run packages/producer/src/services/renderOrchestrator.test.ts`
- `bun run --filter @hyperframes/engine test`
- `bun run --filter @hyperframes/engine typecheck`
- `bun run --filter @hyperframes/producer typecheck`
- `bunx oxlint packages/engine/src/utils/htmlTemplate.ts packages/engine/src/utils/htmlTemplate.test.ts packages/producer/src/services/renderOrchestrator.ts packages/producer/src/services/renderOrchestrator.test.ts packages/producer/src/services/htmlCompiler.test.ts`
- `bunx oxfmt --check packages/engine/src/utils/htmlTemplate.ts packages/engine/src/utils/htmlTemplate.test.ts`
- `bun run build:producer`

### Render / browser verification

Verified against two local repros:

1. **Early offset repro**
   - host starts at `2s`
   - child media is scene-local `0-4s`
   - compiled render summary keeps the child video/audio at `start: 2`
   - browser verification via `agent-browser` confirmed the `2.2s` frame still shows the child clip active in the host timeline

2. **Late offset repro**
   - earlier compositions run first, then the target host starts at `20s`
   - child media starts scene-local at `1.5s` and should remain visible through `24.5s`
   - compiled render summary keeps the child video/audio at `start: 21.5`, `end: 25.5`
   - browser verification via `agent-browser` confirmed the `24.5s` frame still shows the late clip visible, which is the exact tail-clipping case the old reconcile path could break

## Notes

- the `/tmp/hf-pr475-repro` and `/tmp/hf-pr476-late-offset-repro` projects plus their browser-proof artifacts are verification-only and are not part of this PR
- this PR stays narrowly scoped to sub-composition media timing across compile, recompile, and browser probe reconciliation; it does not broaden into general sub-composition HTML normalization beyond the single-wrapper case

James Russo 57cdf7d80e 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)

James Russo 9912d3730a perf(engine): segment-scope SDR→HDR preflight (#445)
## What

Scopes the SDR→HDR preflight re-encode to the segment the composition actually uses, mirroring the existing VFR→CFR segment-scope fix.

## Why

`convertSdrToHdr` was re-encoding entire source files, so a 30-minute SDR screen recording contributing a 2-second clip in a mixed HDR/SDR composition ate multi-second preflight time that produced frames no one would ever read. Validated on a mixed 30s-SDR + 2s-HDR fixture: `hdrPreflightMs` drops **87%** (1162→148ms), `videoExtractMs` drops **82%** (1272→231ms), `tmpPeakBytes` drops **45%** (8.2MB→4.5MB).

Depends on #444 (phase-level instrumentation) for the measurement surface.

## How

- `convertSdrToHdr` gains `startTime` and `duration` parameters ahead of the upstream `targetTransfer` arg added by #370. New signature: `convertSdrToHdr(input, output, startTime, duration, targetTransfer, signal, config)`. `-ss $start -t $duration` is added to the ffmpeg args.
- Phase 2 now captures the full `VideoMetadata` per `resolvedVideos` entry (previously just `colorSpace`) so the caller can compute `segDuration` from `video.end - video.start` with a fallback to `metadata.durationSeconds - video.mediaStart` for unbounded (Infinity) clips — without firing another ffprobe.
- After a successful convert, `entry.video.mediaStart` is zeroed out via shallow-copy (doesn't mutate the caller's `VideoElement`) so downstream extraction seeks from 0 instead of the original offset. Mirrors what the VFR→CFR path already does.

## Test plan

Validation on `/tmp/hf-fixtures/hdr-sdr-mixed-scope`:
```
hdrPreflightMs: >1000 → 150   (gate: <300)   ✓
videoExtractMs: 1272  → 237   (-82%)
tmpPeakBytes:   8.2MB → 4.5MB (-45%)
```

- [x] Unit test: new regression test synthesizes 10s SDR + 2s HDR fixture inline and asserts the converted file's duration matches the 2s used segment (pre-fix matched the 10s source)
- [x] Lint + format
- [x] Typecheck
- [x] Manual perf validation against synthesized fixture

James Russo 31354d52da perf(engine): extraction-phase instrumentation (#444)
## What

Adds per-phase timings and counters to `extractAllVideoFrames` and surfaces them on the producer's `RenderPerfSummary` as `videoExtractBreakdown` alongside a new `tmpPeakBytes` workDir size sample.

## Why

Phase 2 video extraction has five distinct sub-phases (resolve, HDR probe, HDR preflight, VFR probe, VFR preflight, per-video extract) and today they collapse into a single `videoExtractMs` stage timing. That makes every subsequent perf PR in this stack immeasurable — you can't tell whether a win came from cache hits, preflight scope reduction, or pure extraction speed.

This PR is foundational for PR #445 (segment-scope HDR preflight) and PR #446 (content-addressed extraction cache).

## How

- New `ExtractionPhaseBreakdown` type with `resolveMs`, `hdrProbeMs`, `hdrPreflightMs/Count`, `vfrProbeMs`, `vfrPreflightMs/Count`, `extractMs`, `cacheHits`, `cacheMisses`. Populated inline with `Date.now()` wrappers — overhead is sub-millisecond on every phase.
- Returned on `ExtractionResult.phaseBreakdown`.
- Producer extends `RenderPerfSummary` with `videoExtractBreakdown?: ExtractionPhaseBreakdown` and `tmpPeakBytes?: number`. `tmpPeakBytes` is sampled from the workDir right before cleanup via a new recursive-size helper that swallows errors (purely observational — a missing workDir must never fail the render).

No changes to the capture-lifecycle resource tracking — earlier versions of this instrumentation plumbed injector LRU stats through `RenderOrchestrator`, which conflicted hard with upstream #371 (`buildHdrCaptureOptions` refactor). Dropped that piece for a marginal observability loss.

## Test plan

Validation on `packages/producer/tests/vfr-screen-recording`:
```json
"videoExtractBreakdown": {
  "resolveMs": 0, "hdrProbeMs": 0, "hdrPreflightMs": 0, "hdrPreflightCount": 0,
  "vfrProbeMs": 0, "vfrPreflightMs": 166, "vfrPreflightCount": 1,
  "extractMs": 97, "cacheHits": 0, "cacheMisses": 0
},
"tmpPeakBytes": 4578598
```
Total elapsed within noise of pre-PR baseline (2665 → 2673 → 3228ms across hosts).

- [x] Unit test: phase-breakdown assertion added to `videoFrameExtractor.test.ts`
- [x] Lint + format (oxlint + oxfmt)
- [x] Typecheck (engine + producer)
- [x] Manual perf validation against VFR fixture

Vance Ingalls bb9e6bdf05 test(engine): lock down sRGB→BT.2020 LUT with byte-exact reference values (#377)
## Summary

Add a 12-row reference table covering the full sRGB range with byte-exact 16-bit HLG and PQ signal values, plus three guard tests, locking down the `buildSrgbToHdrLut()` math.

## Why

`Chunk 9F` of `plans/hdr-followups.md`. The matrix-free fast path through `blitRgba8OverRgb48le` runs every DOM pixel through `buildSrgbToHdrLut()` (sRGB EOTF → linear → HDR OETF → 16-bit). Any drift in the EOTF/OETF math — constant changes, branch swaps, rounding-mode regressions — would silently corrupt every text / UI / overlay pixel composited onto an HDR frame.

Existing tests covered structural invariants (transparent passthrough, opaque overwrite, alpha blending, channel symmetry, HLG ≠ PQ) but no byte-exact reference values, so a uniform scale or constant tweak could pass everything.

## What changed

- 12-row reference table in `alphaBlit.test.ts` covering black, shadow, mid-grays, highlight, near-white, and white with exact 16-bit HLG and PQ signal values.
- Three guard tests:
  - **Asymmetric R/G/B (HLG):** each channel hits the LUT independently.
  - **Asymmetric R/G/B (PQ):** same, on the PQ path.
  - **BT.2408 SDR-white invariant:** PQ caps sRGB 255 at 38055 (~203 nits), well below HLG's 65535. This is the load-bearing detail that makes PQ headroom work — locking the exact value prevents a future "fix" that would re-scale PQ to peak-at-SDR-white and clip every real HDR pixel.

Reference values mirror `buildSrgbToHdrLut()` exactly and were verified against the existing HLG mid-gray comment in the file.

## Test plan

- [x] All new tests pass against the current LUT.
- [x] Existing `alphaBlit.test.ts` invariants unchanged.

## Stack

Chunk 9F of `plans/hdr-followups.md`. Test-only change, independent of all other chunks.

Vance Ingalls 3089c8ee3a build(lfs): track tests/*/src/*.png via Git LFS (#376)
## Summary

Track `tests/*/src/*.png` via Git LFS to mirror the existing policy for golden videos and `.mp4` fixtures.

## Why

`Chunk 11C` of `plans/hdr-followups.md`. Without this rule, regression suites that grow PNG fixtures over time would bloat the working-tree history and slow shallow clones.

## What changed

- `.gitattributes`: add `tests/*/src/*.png` to the LFS-tracked patterns.
- Migrates the six existing PNG fixtures (1.6 MB combined: `hdr-photo-pq.png` plus `heygen-promo-preview-assets/` screenshots) onto LFS in the same commit so the rule applies retroactively.

## Test plan

- [x] `git lfs ls-files` includes the HDR PNG fixtures after commit.
- [x] Working tree size for these files goes from 1.6 MB to 6 × ~130 B LFS pointers.

## Stack

Chunk 11C of `plans/hdr-followups.md`. Independent of all code changes.

Vance Ingalls a3d7cc1c95 refactor(producer): extract HDR compositing helpers and rename media metadata (#373)
## Summary

Four behavior-preserving refactors that reduce complexity in `renderOrchestrator.ts` and clarify the engine ffprobe utility surface. Lands after the correctness fixes (Chunks 1–5) so the refactored code is already correct.

## Why

`Chunk 7` of `plans/hdr-followups.md`. The HDR composite block had grown a ~200 LOC inline closure with 14 captured deps, a repeated capture-options spread, a `extractVideoMetadata` name that now also handles still images, and per-frame re-creation of debug helpers.

## What changed

**7A — Hoist `compositeToBuffer` into a module-scoped helper.** Extract the inline HDR closure into a top-level `compositeHdrFrame()` that takes an `HdrCompositeContext` struct. Construct the context once at the top of the HDR render block and pass it through. Removes a deeply-nested closure from the middle of the orchestrator.

**7B — `buildHdrCaptureOptions()` helper.** Factor the repeated `{ ...captureOptions, skipReadinessVideoIds: ... }` spread into a named helper at the call site.

**7C — Rename `extractVideoMetadata` → `extractMediaMetadata`.** Reflects that the helper handles still images (PNG/JPEG/WebP) in addition to video. Update all callers in engine + producer (`videoFrameExtractor`, `htmlCompiler`, regression-harness, producer ffprobe re-export, tests). Re-export the old name as a deprecated alias from `@hyperframes/engine` for backward compatibility, plus the producer re-export shim.

**7D — Hoist debug counters to module scope.** `countNonZeroAlpha` and `countNonZeroRgb48` are now module-scoped so they aren't re-created per frame and so the closure has fewer captures.

Also touches the `hdr-regression` and `hdr-hlg-regression` README + `meta.json` files reviewed during this refactor.

## Test plan

- [x] `bunx tsc --noEmit -p packages/producer && bunx tsc --noEmit -p packages/engine` clean.
- [x] Engine tests: 313 pass, 0 fail (1218 expect calls).
- [x] `bunx oxlint` + `bunx oxfmt --check` clean on 8 changed source files.
- [x] Diff is structural only — no behavioral changes.

## Stack

Chunk 7 of `plans/hdr-followups.md`. Lands after the correctness fixes (Chunks 1–5) per the suggested merge order.

## What

Replace the `choco install ffmpeg` step in `windows-render.yml` with a direct download of the upstream Windows GPL build from [`BtbN/FFmpeg-Builds`](https://github.com/BtbN/FFmpeg-Builds/releases/latest) on GitHub Releases.

## Why

The `Render on windows-latest` canary started failing on every PR with:

```
[NuGet] Response status code does not indicate success: 504 (Gateway Timeout).
[NuGet] Response status code does not indicate success: 503 (Service Unavailable).
```

The Chocolatey community feed (`community.chocolatey.org/api/v2/package/ffmpeg/8.1.0`) is degraded for the `ffmpeg` package right now. The earlier 3-attempt retry I added wasn't enough — every attempt across multiple runs failed with 503/504, so retrying does nothing.

The Chocolatey path is also a bit indirect for what this job actually validates. The real point of the canary is the [PR #336](https://github.com/heygen-com/hyperframes/pull/336) fix where `findFFmpeg()` / `where ffmpeg` discovery has to work on a fresh Windows runner. As long as `ffmpeg.exe` ends up on `PATH`, the underlying thing under test (the harness can find ffmpeg, capture frames, mux to MP4) is exercised exactly the same.

BtbN/FFmpeg-Builds is the canonical upstream nightly Windows GPL build (Chocolatey itself rebundles essentially the same artifact), so this is closer to the source, not further from it.

## How

- Download `ffmpeg-master-latest-win64-gpl.zip` from the BtbN release with `Invoke-WebRequest` (3-attempt retry with backoff).
- Extract to `$env:RUNNER_TEMP/ffmpeg` and locate `ffmpeg.exe` recursively.
- Add the bin directory to `$env:GITHUB_PATH` so all subsequent steps in the job (the Bun-driven harness, `findFFmpeg()`, etc.) see ffmpeg on `PATH` exactly the same way as before.
- Print `ffmpeg -version` as a sanity check.

## Test plan

- [ ] CI: `Render on windows-latest` job goes green on this PR.
- [ ] Subsequent PRs no longer get blocked on `choco install ffmpeg` 503s.

Vance Ingalls 5256a93b2d 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).

James RussoandClaude Opus 4.7 ffc06827c4 fix(engine): auto-normalize VFR video inputs to CFR before frame extraction (#360)
* fix(engine): auto-normalize VFR video inputs to CFR before frame extraction

Screen recordings (macOS ScreenCaptureKit, QuickTime, phone videos) are
commonly variable-frame-rate. When such inputs hit the extractor's
`-ss <start> -i <video> -t <dur> -vf fps=N` pipeline, the fps filter
can emit fewer frames than requested — for a 4-second 30fps segment
starting mid-file, the output was ~90 frames instead of 120.

`FrameLookupTable.getFrameAtTime` returns null for out-of-range indices,
so the compositor held the last valid frame and the user perceived the
video as freezing. This matches the bug report from an X community post
where a user said "all of them freezes" on their screen recording scenes.

The engine already detects VFR via `metadata.isVFR` in ffprobe.ts but
never acted on it — the compiler only logged a warning. This change
mirrors the existing SDR→HDR normalization pattern: when a source is
detected as VFR, re-encode only the used segment with
`-fps_mode cfr -r <fps> -preset fast -crf 18` before extraction.

Scoping the re-encode to `[mediaStart, mediaStart+duration]` means a
30-second clip cut from a 60-minute screen recording pays ~1s of
transcode cost, not 18s. Benchmarked locally:

  Baseline (current):         32-39% duplicate frames, 25% frame-count
                              shortfall on mid-file segments.
  Tier 1 (flag changes only): ~same — fps filter issue is not flag-fixable.
  Tier 2 (CFR preflight):     1.7-6% duplicate frames, correct frame
                              count in every scenario tested.

The compiler warning that previously told users to manually re-encode
is downgraded to `console.info` since the engine now handles it.

* refactor(engine): clean up VFR normalization loop after review

- Drop the `vfrNormDirCreated` flag; `mkdirSync({recursive:true})` is
  idempotent and cheap.
- Don't re-wrap the `VFR→CFR conversion failed` prefix — `convertVfrToCfr`
  already throws a message with that label; adding it again in the catch
  produced "VFR→CFR conversion failed: VFR→CFR conversion failed (exit 1)".
- Shorten the Phase 2b header comment; the function docstring above
  `convertVfrToCfr` already explains the failure modes and rationale.
- Note which frame windows the VFR fixture's select filter drops so the
  magic numbers are scannable.

No behavior change; 311/311 engine tests still pass.

— Rames Jusso

* test(engine): add VFR regression unit tests

Adds a describe block that synthesizes a VFR fixture via ffmpeg and asserts
the extractor produces the expected frame count (no shortfall) and no long
runs of duplicate frames — the user-visible "frozen screen recording"
symptom. Covers both a mid-file segment and the full-file case.

Guarded with describe.skipIf(!HAS_FFMPEG) because the CI Test job on
ubuntu-24.04 and the Windows test-windows job don't install ffmpeg. The
producer-level regression test in packages/producer/tests/vfr-screen-recording/
runs inside Dockerfile.test (which has ffmpeg) and is the primary CI signal
for this bug; these unit tests are supplementary coverage for local and
any ffmpeg-equipped CI environment.

* test(producer): add vfr-screen-recording regression test

End-to-end CI regression coverage for PR #360 via the existing
regression-harness: renders a 3s composition containing a real macOS
ScreenCaptureKit clip (r_frame_rate=120, avg≈36fps) seeked to
mediaStart=1, then PSNR-compares against a committed output.mp4.

Fixture src/clip.mp4 (108 KB) is a 5-second excerpt downscaled to 480×332
with -fps_mode passthrough to preserve the VFR timestamps. Content is the
public hyperframes OSS repo root page — see NOTICE.md for provenance.

With the fix applied, all 100 PSNR checkpoints pass. With the fix reverted,
66 of 100 fail (PSNR drops from ~43 dB to ~20 dB in the duplicate-frame
windows). Tagged "regression,video,vfr" so it runs in the fast shard
of .github/workflows/regression.yml automatically.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test(producer): regenerate vfr-screen-recording baseline in Docker

The committed golden output.mp4 was initially rendered on the host machine;
CI runs the renderer inside Dockerfile.test with a different Chrome +
ffmpeg build, producing pixel-level drift that failed PSNR at 54/100
checkpoints (~20 dB vs 41 dB in the VFR sparse-content windows). Both
renders are valid — the VFR source has inherent sampling ambiguity in
static segments, and different Chrome/ffmpeg builds make different valid
choices.

Regenerated the baseline via `bun run docker:test:update vfr-screen-recording`
so it matches the Docker environment CI actually uses. Matches the flow
the existing sub-composition-video, hdr-pq, etc. baselines were captured
with.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: document that producer test baselines must be captured in Docker

Hit this 2026-04-21 with the vfr-screen-recording regression test:
host-generated output.mp4 baseline tripped 54/100 PSNR checkpoints in CI
because Chrome + ffmpeg drift between the host and Dockerfile.test.

Document the `bun run --cwd packages/producer docker:test:update <name>`
flow so future contributors don't repeat the mistake.

Vance Ingalls 00af29c169 fix(cli): forward --hdr through Docker render + HDR docs (#346)
## Summary

This PR ended up covering the full HDR Docker/docs follow-through plus the producer/engine work needed to make HDR still images render and regress correctly in CI.

The branch now does four things:

- forwards `--hdr` through the Docker render path in the CLI
- adds and expands HDR documentation across the docs site
- adds first-class HDR still-image support to the engine/producer pipeline
- adds targeted HDR regression coverage, including a CI-safe fallback for PNG HDR metadata detection when `ffprobe` does not expose PNG color tags

## What changed

### CLI and docs

- `hyperframes render --docker --hdr` now preserves `--hdr` when invoking the in-container CLI
- added a dedicated HDR guide and linked it from CLI, producer, engine, rendering, and common-mistakes docs
- documented HDR constraints and verification flow: HDR source requirements, MP4/H.265 Main10 output, PQ/HLG handling, Docker usage, and common SDR fallback causes

### Engine and producer HDR image support

- added `ImageElement` support to the engine composition model and parsing path
- threaded image elements through producer compilation and orchestration
- probed image sources for HDR color spaces so image-only compositions can trigger HDR output without requiring an HDR video source
- included HDR image start times in stacking queries so the layered compositor can place images correctly in z-order
- integrated HDR image compositing into the layered HDR render loop alongside native HDR video layers and SDR DOM overlays
- forced screenshot mode for HDR layered compositing where required to keep DOM/HDR layer composition deterministic
- skipped readiness waiting for natively extracted HDR videos in the engine path where it was unnecessary and could block layered HDR flows

### HDR metadata robustness

- added a fallback in `extractVideoMetadata()` to read PNG `cICP` metadata directly when `ffprobe` omits color-space fields for PNGs
- this specifically fixes CI/Docker detection for the `hdr-image-only` fixture, where the render was falling back to SDR because the PNG was not being recognized as BT.2020 PQ

### Regression coverage and fixture cleanup

- added `hdr-image-only`, a regression fixture that validates HDR still-image rendering end to end
- added `hdr-pq`, a focused HDR PQ regression fixture for the video path
- updated regression CI to run an `hdr` shard with `--sequential hdr-pq hdr-image-only`
- removed the older larger `hdr-regression/*` fixture set in favor of the smaller targeted regressions used by CI
- added the necessary fixture generation/readme material and checked-in golden outputs for the new HDR tests

## Why

The original PR description only covered the CLI flag forwarding and docs work. Since then, the branch also picked up the missing runtime support needed for HDR still images and the regression coverage to keep that path from breaking.

The practical issue this closes is:

- local host runs could pass while CI failed `hdr-image-only`
- the failure was a full-frame visual mismatch caused by SDR fallback, not unstable rendering
- root cause was PNG HDR metadata not being surfaced by `ffprobe` in the CI Docker environment
- parsing the PNG `cICP` chunk directly makes HDR detection deterministic across environments

## Test plan

### Local targeted checks

```bash
bunx oxlint packages/engine/src/utils/ffprobe.ts packages/engine/src/utils/ffprobe.test.ts
bunx oxfmt packages/engine/src/utils/ffprobe.ts packages/engine/src/utils/ffprobe.test.ts
bun --cwd packages/engine test src/utils/ffprobe.test.ts src/utils/hdr.test.ts
```

### Producer regression runs on host

```bash
bun run --cwd packages/core build:hyperframes-runtime:modular
bun --cwd packages/producer test -- --sequential --exclude-tags slow,render-compat,hdr
bun --cwd packages/producer test -- --sequential hdr-pq hdr-image-only
```

Observed result:
- `fast` shard: 7 passed, 0 failed
- `hdr` shard: 2 passed, 0 failed

### CI-equivalent Docker verification

```bash
docker build -f Dockerfile.test -t hyperframes-producer:test .

docker run --rm \
  --security-opt seccomp=unconfined \
  --shm-size=4g \
  -v "$PWD/packages/producer/tests:/app/packages/producer/tests" \
  hyperframes-producer:test \
  --sequential hdr-pq hdr-image-only
```

Observed result:
- `hdr-image-only`: passed
- `hdr-pq`: passed
- shard summary: 2 passed, 0 failed

### Specific regression fixed

Before the PNG `cICP` fallback, the Docker/CI run failed `hdr-image-only` with:

- missing `"[Render] HDR source detected — output: PQ ..."` log line
- full-frame visual mismatch across all 100 checkpoints
- PSNR ~17 on every frame, indicating a consistent SDR-vs-HDR pipeline mismatch

After the fallback, the same Docker path recognizes the PNG as HDR and the shard passes.

Vance Ingalls 5a3fde19d4 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.

Miguel Ángel 0cf03016b2 fix(engine): resolve external asset paths from compiled dir (#231)
## Summary
- Parent-relative paths (e.g. `src="../file.wav"`) silently drop media from rendered MP4
- The compiler rewrites external paths to `hf-ext/` and copies files to the compiled directory, but both the audio mixer and video frame extractor only resolved against `projectDir` — never finding them
- Now checks `compiledDir` first (matching the file server's resolution order), then falls back to `projectDir`
- Fixes both `<audio>` and `<video>` elements with external paths

## Real-world context
Reported in Slack by Abhai — a TTS comparison video using `<audio src="../tts-voxcpm2.wav">` (audio file in parent directory, composition in subdirectory) rendered successfully but the output MP4 had no audio stream. The render completed without any error, silently dropping the audio.

## Testing

### Environment
- Linux (Ubuntu 20.04), ffmpeg 4.2
- Test composition: `subdir/index.html` with `<audio id="bg-audio" src="../test-audio.wav">`, WAV file at parent directory

### Before fix (main)
```
[AUDIO-DEBUG] element.src=hf-ext/tmp/hf-test-231/test-audio.wav
              baseDir=/tmp/hf-test-231/subdir
[AUDIO-DEBUG] resolved srcPath=/tmp/hf-test-231/subdir/hf-ext/tmp/hf-test-231/test-audio.wav
              exists=false
```

- Audio mixer tries `join(projectDir, "hf-ext/...")` → file doesn't exist at that path
- Output: **9.8 KB, video stream only** (confirmed via ffprobe)
- No error logged — audio silently dropped

### After fix (this branch)
```
[AUDIO-DEBUG] element.src=hf-ext/tmp/hf-test-231/test-audio.wav
              baseDir=/tmp/hf-test-231/subdir
              compiledDir=/tmp/.../compiled
[AUDIO-DEBUG] fromCompiled=/tmp/.../compiled/hf-ext/tmp/hf-test-231/test-audio.wav
              exists=true
[AUDIO-DEBUG] resolved srcPath=/tmp/.../compiled/hf-ext/tmp/hf-test-231/test-audio.wav
              exists=true
[AUDIO-RESULT] success=true, hasAudio=true
```

- Audio mixer checks `join(compiledDir, "hf-ext/...")` first → file found
- Output: **44.6 KB, video + audio streams** (confirmed via ffprobe)

### ffprobe comparison

| Branch | File size | Streams |
|--------|-----------|---------|
| `main` | 9.8 KB | `video (h264)` only |
| `fix` | 44.6 KB | `video (h264)` + `audio (aac)` |

### Path resolution flow
1. Compiler sees `<audio src="../test-audio.wav">`
2. Compiler resolves to absolute path, maps it to `hf-ext/tmp/.../test-audio.wav`
3. Compiler copies file to `compiled/hf-ext/tmp/.../test-audio.wav`
4. Audio mixer gets `element.src = "hf-ext/tmp/.../test-audio.wav"`
5. **main**: tries `join(projectDir, src)` → not found → silent drop
6. **fix**: tries `join(compiledDir, src)` first → found → audio mixed in

### Repro
```bash
mkdir -p /tmp/test/subdir
ffmpeg -f lavfi -i "sine=frequency=440:duration=2" /tmp/test/test-audio.wav -y
# Create subdir/index.html with <audio src="../test-audio.wav" ...>
cd /tmp/test/subdir && npx hyperframes render
ffprobe -v error -show_streams output.mp4  # video only on main, video+audio on fix

Miguel Ángel 110ea12597 fix(core,engine,producer): handle id-less media in sub-composition renders (#96)
## What

Move the id-less media fix into the shared timing compiler so producer can resolve durations for sub-composition videos before inlining, then carry the merged result through engine parsing, regression coverage, and the regression Docker image used in CI.

This PR now does five concrete things:

- assigns stable ids to id-less media in core `compileTimingAttrs()` so unresolved duration injection can target them
- keeps the engine-side `parseVideoElements()` support for `video[src]` plus the newer `data-duration` / natural-duration fallback from `main`
- makes producer prefer sub-composition media metadata over the later inlined-document parse when the same media id appears in both places
- makes `sub-composition-video` a runnable regression test by fixing its metadata and checking in the missing `output/compiled.html` snapshot
- removes the stale `pnpm-workspace.yaml` copy step from `Dockerfile.test`, so regression CI builds the Bun-based test image from the current workspace layout

## Why

- media without an explicit `id` could not participate in unresolved-duration resolution early enough
- producer could lose the resolved sub-composition timing by overwriting it with the later inlined parse
- the regression fixture intended to cover this case was not actually running in CI because its `meta.json` was incomplete and the required compiled snapshot was missing
- the regression image definition still expected a deleted `pnpm-workspace.yaml`, so GitHub Actions failed before the test shard could start

Putting the id-generation step in core makes the behavior reusable instead of relying on producer-only HTML patching.

## How

### Shared compiler

- core `compileTimingAttrs()` now auto-assigns stable ids to id-less `video` / `audio` tags
- those generated ids are returned in `unresolved`, so `injectDurations()` can add `data-duration` and `data-end` to the same media element later in the pipeline
- added core tests that cover auto-id assignment and duration injection for generated ids

### Producer

- when producer combines `subVideos` / `subAudios` with the media re-parsed from the final inlined HTML, it now lets the sub-composition metadata win
- this preserves the resolved/clamped timing already computed for nested media instead of overwriting it with the later parse
- `sub-composition-video` now has valid regression metadata and a checked-in `output/compiled.html` snapshot so CI actually executes it

### Engine

- resolved the merge conflict in `videoFrameExtractor` by keeping the broader `video[src]` parsing from this branch and the `data-duration` / natural-duration fallback that landed on `main`
- added a focused engine unit test for videos without ids

### CI image

- `Dockerfile.test` now copies only `package.json` and `bun.lock` at the workspace root before `bun install --frozen-lockfile`
- this matches the current monorepo layout and removes the obsolete pnpm-era dependency on `pnpm-workspace.yaml`

## Test plan

- [x] `bun run --filter @hyperframes/core test`
- [x] `bun run --filter @hyperframes/engine test`
- [x] `bun run --filter @hyperframes/producer test --update --sequential sub-composition-video`
- [x] `bun run --filter @hyperframes/producer test --sequential sub-composition-video`
- [x] Browser check with `agent-browser` against the compiled fixture page (`http://127.0.0.1:8123/compiled.html`)
- [x] Clean tracked-only Docker build of `Dockerfile.test` with the PR version of the file applied

## Notes

- Latest regression workflow is green on `main`, but before this PR the `sub-composition-video` fixture was being skipped by the harness rather than exercised end to end.
- The CI Docker fix was validated from a tracked-only export to avoid local untracked worktree artifacts affecting the result.

Miguel Ángel 1230657ed0 fix(studio,runtime,engine,compiler): 8 bug fixes — audio, render, timeline, Lottie, thumbnails, video render (#133)
## Summary

**Original 5 bugs fixed:**

- **Bug 1 — Audio silent after seek**: Added `Accept-Ranges` / `Content-Length` + `206 Partial Content` to the static asset server for byte-range seeking.
- **Bug 2 — Download 404 after restart**: Render list endpoint now registers on-disk renders into the in-memory job map.
- **Bug 3 — Timeline stops at GSAP end**: `resolveRootTimelineFromDocument` pads the GSAP timeline to match `data-duration` when the composition declares longer.
- **Bug 4 — Render stuck at 0%**: Store `jobState` reference (not spread copy) so async progress mutations reach the SSE stream.
- **Bug 5 — Lottie missing in preview/render**: Two fixes — (a) moved Lottie adapter before GSAP so `onUpdate` wins; (b) fixed bundler silently dropping external CDN `\<script src>` tags from sub-compositions (root cause: `$content(s).html()` returns `""` for external scripts).

**3 additional bugs fixed:**

- **Bug 6 — Blank thumbnails outside monorepo**: Implemented `generateThumbnail` in the CLI adapter using Puppeteer.
- **Bug 7 — Video empty in rendered sub-compositions**: Fixed `parseVideoElements` selector from `video[id][src]` to `video[src][data-start]` + auto-assign IDs.
- **Render errors**: Failed renders now show their error message in the renders panel.

Vance IngallsandClaude Opus 4.6 9f8e5ba5a1 initial code (#2)
* feat: initial code port from hyperframes-internal

Port all OSS-ready packages from the internal monorepo:
- @hyperframes/core — shared types, HTML generation, GSAP utilities, runtime
- @hyperframes/cli — CLI for creating, previewing, and rendering compositions
- @hyperframes/engine — framework-agnostic rendering engine (BeginFrame + FFmpeg)
- @hyperframes/producer — video rendering pipeline (Puppeteer + FFmpeg)
- @hyperframes/ui-player — browser-based video player component
- @hyperframes/studio — composition editor (React frontend + Hono backend)

Includes regression test suite with Docker-based test harness.

All HeyGen-internal references, deployment infrastructure, and
proprietary assets have been removed. Package names migrated
from @app/* to @hyperframes/*.
