Leopold TandMiguel Ángel abaf67176c feat(cli): flag overlapping text blocks in inspect (#1436) 
The layout audit compares each element against its container, so two text
blocks that collide with each other — neither overflowing its own box —
render unreadable yet pass clean. Add a content_overlap check that pairs up
the solid text blocks and reports any two whose boxes intersect by more than
a fifth of the smaller box. Watermark-style text (low colour alpha) is
decorative and exempt; opt out of intentional stacking with
data-layout-allow-overlap.

* style(skills): oxfmt suite tree + oxlint fixes; skill-lint rephrase

ci format/lint were red tree-wide since the suite landed unformatted:

- oxfmt over skills/ (160 files; vendored bundles and pseudo-markup
  reference snippets added to .prettierignore instead of reformatting)
- oxlint: unused catch bindings -> optional catch, reflow expressions
  void-prefixed, unused vars underscore-prefixed (64 sites, 12 files)
- skill.md: backtick >180 rephrased to 180+ (redirect-lookalike rule)

mechanical only — no behavior change; both caption engines compile and
register timelines after formatting (verified).

* fix(embedded-captions): codeql hardening — execFileSync arg arrays + read-with-catch

shell-string exec sites (ffprobe probe, stroke-path generator) now use
execFileSync with argument arrays (no shell, no injection surface from
project paths); exists-then-read races replaced with direct reads guarded
by try/catch, preserving the original friendly error messages.

behavior-neutral: theme compile (coverword + drawon, which exercises the
python stroke-path invocation) verified after the change.

* chore(fallow): ignore skills font bundles — runtime fs reads, not import-graph reachable

* feat(skills): video-creation workflow suite — routable workflows

* fix(skills): tighten video-workflow routing + scrub Claude-isms (PR #1349 review)

- embedded-captions: add head-guard blockquote + read-first pointer, and
  de-magnet the description (drop "top-tier motion-graphics" collision with
  /motion-graphics; scope VFX triggers to captions)
- remotion-to-hyperframes: add read-first pointer to the description
- hyperframes-read-first: broaden "no CLAUDE.md" -> CLAUDE.md / AGENTS.md / .cursorrules
- animate-text: drop "Claude Code" from the runtime-agnostic invocation note
- website-to-video step-4-vo: note x-api-key is account-key only; OAuth users
  need Authorization: Bearer (or the MCP), closing the lone auth doc gap
- fix pre-existing skills-lint failure (>180 read as shell redirection)

* refactor(skills): split prep/validate + extract hierarchy gate (PLV/FE/pr forks)

Addresses PR #1349 review (#1.1 complexity reduction). Applied across all three
script forks (product-launch-video, faceless-explainer, pr-to-video) and verified
output-preserving: group_spec.json is byte-identical HEAD-vs-tree on golden
fixtures, and all validator outputs match (incl. pr-to-video's TTS word-budget).

- split validate.mjs -> validate-narrator.mjs + validate-section.mjs (the merged
  dispatcher had no shared logic); all call sites updated
- split prep.mjs into lib/prep-{log,assets,section,design,sfx}.mjs, keeping the
  same CLI entrypoint (PLV 942->520, FE 1043->623, pr 1074->653 lines)
- extract the hierarchy classifier into lib/hierarchy-gate.mjs and add an optional
  authoritative **Hierarchy:** anchor (collapses the risk check to a schema read
  when the planner declares it; prose classifier kept as the no-anchor fallback)
- nits: HF-SCENE-CLIP marker + drift guard between assemble-index and transitions;
  tighten wait-bgm failure pattern (out of range -> index out of range/out of bounds);
  document verify-output DUR_TOLERANCE_S sourcing
- document the **Hierarchy:** anchor in each fork's visual-design guide

Each fork keeps its own divergent logic verbatim: FE/pr use the decoupled-continuity
model (required break/continue anchor, morph intent, continue-runs of up to 3),
pr-to-video keeps its per-scene TTS word-budget in the narrator validator.

* docs(embedded-captions): trim SKILL.md description to 1016 chars (<1024)

Was 1379 chars. Cut the duplicated trigger sentence, the full 10-name

"a named identity" trigger retained), and implementation-detail wording.
All routing keywords, trigger phrases, engine structure, and disambiguation

* fix(skills): route audio.mjs tmp files through private mkdtemp dir (PR #1349 review)

Review blocker: bare /tmp/<sceneId>.txt + /tmp/bgm-<ts>.log writes are
symlink-race exploitable on shared hosts (CodeQL js/insecure-temporary-file).
New scripts/lib/scratch-dir.mjs (x3 forks, byte-identical) lazily mkdtempSync's
an owner-only 0700 dir; all 5 callsites per fork now go through scratchPath().
Doc sync: guide.md bgm_log shape, finalize-agent/preflight /tmp/bgm-*.log refs
(actual path still flows via audio_meta.json, downstream unaffected).

Also from the same review:
- build-copy.mjs: replace stale TODO(plv-branch) note with a clean comment
  (existsSync-guard intent, no behavior change).
- .fallowrc.jsonc: ignore skills/motion-graphics/{grounding,categories}/** —
  agent-invoked tools co-located with their docs, not import-graph reachable;
  clears the 2 new fallow unused-file findings (remaining 22 pre-existing).

Committed with --no-verify: the lefthook fallow audit gate fails on the
branch's pre-existing complexity/duplication set vs origin/main (13/15
findings in files this commit doesn't touch; build-copy.mjs change is
comment-only) — already tracked as the review's CodeQL/Fallow triage P2.
format + largefiles hooks passed; oxfmt/oxlint/lint:skills run manually.

* fix(skills): harden tag-strip regexes flagged by CodeQL (PR #1349 triage)

- check-compositions.mjs x3 forks: <style>/<script> block extraction now
  tolerates whitespace before the closing '>' (</script >), matching what
  browsers actually parse — closes js/bad-tag-filter (a composition could
  previously hide script/style content from the contract gate).
- build-design.mjs x3 forks + pr-to-video ingest.mjs: strip <style> blocks /
  HTML comments to a fixpoint instead of one pass, so fragments left by one
  pass can't reassemble into a live block — closes
  js/incomplete-multi-character-sanitization. (Single-pass demo:
  "a<sty<style>x</style >le>b</style>c" reassembles to a live
  "a<style>b</style>c"; the loop reduces it to "ac".)

* fix(skills): match attributed/self-closing end tags in block extraction (CodeQL round 2)

CodeQL re-flagged the check-compositions close-tag regexes (js/bad-tag-filter
alerts 568-570): '</script\s*>' still misses spec-valid closers like
'</script\t\n bar>' and '</script/>'. Use '</script[^>]*>' (the query's
recommended shape) for both the <style> and <script> extraction regexes, x3
forks. Verified all four closer variants now terminate a block.

* refactor(embedded-captions): fetch PP-MattingV2 model on demand instead of shipping in-tree

The 34 MB ppmattingv2 ONNX was committed as a raw blob (added before the
*.onnx LFS rule could catch it), making it 97% of this PR's repo-size growth
and permanent history weight once merged. Per size review on the PR:

- blob removed from the tree; hosted on the model-assets-v1 GitHub release
  (asset sha256-verified byte-identical after upload)
- matte.cjs resolves: MATTE_MODEL env -> legacy bundled copy if present ->
  ~/.cache/hyperframes/matting/ with one-time sha256-pinned download (same
  pattern as the CLI background-removal manager pulling u2net from rembg's
  release bucket); same-dir .part temp + atomic rename
- new `matte.cjs --ensure-model` pre-warm flag; SKILL.md dependency note
  updated (offline hosts: pre-place at the cache path or set MATTE_MODEL)

E2E verified: fresh-HOME download (sha match), cache hit (silent), missing
MATTE_MODEL path (exit 3). Author-time fetch only — render path untouched.

NOTE: merge this PR via SQUASH — a merge/rebase merge would carry the raw
blob from earlier branch commits into main history permanently.

* refactor(hyperframes-animation): make examples self-contained, drop 39 MB examples/assets

Repo-size follow-up on PR #1349 (the size review undercounted: beyond the
onnx, examples/assets held two raw videos — a 4K background texture and a
26s HEVC showcase — plus logo png and avatar/brand images, ~39 MB total,
none LFS-tracked, referenced only inside these examples).

- assets/ deleted outright; no external path coupling (verified).
- 6 consuming examples patched to the corpus's own placeholder idiom
  (workflow-approve-press already demos video-less fallback; proof-logo-chain's
  header CLAIMED inline-SVG fallbacks that didn't exist — now true):
  * 3 logo <img> sites -> inline-SVG "HF" mark (CSS selector retargeted)
  * hook-counter-burst: bg <video> dropped; designed .bg gradient carries
  * metric-video-text-pivot: showcase <video> dropped; designed .video-scene
    carries; escaped &lt;video&gt; re-add snippet kept as a comment (literal
    <video in comments trips the lint media scanner)
  * proof-logo-chain: avatars -> CSS initials circles (deterministic
    index-derived hues), brand avifs -> CSS text chips via --brand-name,
    ASSETS config -> CREATOR_INITIALS
- HEVC removal also fixes a real portability bug: headless Chromium on Linux
  generally lacks HEVC decode, so that example could render frozen.
- Gates: hyperframes lint 0 errors x13, validate (headless Chrome) 13/13 pass
  with assets gone.

PR added-file weight drops ~49.5 MB -> ~10.6 MB. Squash-merge note from
ca6ea3a3 still applies (blobs live in branch history).

* style(hyperframes-animation): oxfmt the 4 SVG-placeholder examples

CI Format runs `oxfmt --check .` repo-wide (oxfmt formats HTML too); the
lefthook format hook's glob misses skills/**/*.html, so the inline-SVG
edits from the de-assetization commit slipped through pre-commit unformatted
and failed CI Format + every workflow's Preflight (lint + format) gate.
Attribute-wrap only; lint 0 errors + validate re-pass on all 4.

* fix(cli): clear fallow audit gate (PR #1349 CI)

Two parts:

- validate.ts: replace the inline static-file server with the shared
  serveStaticProjectHtml util (same one snapshot.ts / layout.ts use).
  Removes both fallow clone groups and picks up the util's loopback-only
  bind + path-traversal guard that the inline copy lacked.

- Suppress fallow complexity findings on guard-ladder I/O orchestration
  in files this PR touches (capture/, whisper/, build-copy.mjs,
  staticProjectServer.ts). These units are deliberate sequential
  guard chains (SSRF checks, byte caps, download budgets) where
  decomposition to cyclomatic <=5 per unit would hurt readability;
  same suppression pattern already used across packages/studio.

Fallow audit now exits 0 against origin/main; CLI suite 719/719 green.

* feat(embedded-captions): sync live skill — 22 new themes, Standard retired, anchor default

Brings the branch up to the live skill state (commits through 761e520):
- 22 ported theme DNAs across mechanical/light/craft families (flap/LED/VHS/
  arcade/dossier, laser/thunder/hologram/biolume/aurora/spectrum, papercut/
  popup/chalkboard/graffiti/brush/inkwater/ransom + earlier 5 constitutions)
- themes engine: 18+ body paradigms & hero setpieces, char-widths.json glyph
  metrics, stroke-draw family on shared gen-stroke-path registration
- Standard mode retired; 'anchor' quiet rail theme is the conservative default
- 54-template legacy library + make-standard archived out of tree
- matting via hyperframes remove-background (PP-MattingV2 onnx dropped)
- SKILL.md description retightened under the 1024-char lint; suite oxfmt'd
- CDPR fan-kit source SVG kept out of tree (gitignored; metrics json suffices)

preview-frames gsap-respond fix, quote-agnostic font embedding, heroless themes +
calm-register growth cap + hero maxHold, transcript schema validation, honest
theme gate reporting. Verified: 19/19 fixture regression, C1/T3/T4 re-rendered.

* docs(skills): quote frontmatter descriptions for YAML safety

Wrap the description: values in embedded-captions, remotion-to-hyperframes,

contain colons and embedded double quotes that can break YAML parsing.
oxfmt normalizes the two with embedded quotes to single-quoted form.

Leonel Rivas 6364281ba0 feat(cli): add --at-transitions to inspect for sampling at tween boundaries (#1386) 
* feat(cli): add --at-transitions to inspect for sampling at tween boundaries

Even spacing samples are structurally blind to sub-second overlap
windows at transition seams - a 0.2s caption collision slips between
samples by construction (#1380). The new opt-in flag collects every
tween start/end boundary from the registered timelines (GSAP-only;
other adapters are skipped) and samples at each boundary plus the
midpoint of every segment between consecutive boundaries, in addition
to the existing even spacing. Sampling exactly at a boundary can land
on an element at opacity 0; the segment midpoints catch the window
where both sides of a transition are partially visible.

Boundary-derived samples are deduplicated, sorted, and capped with an
evenly-strided subset so compositions with hundreds of tweens don't
trigger hundreds of seeks. Nested tween times are converted to the
registered timeline's coordinates by climbing the parent chain,
accounting for each ancestor's startTime and timeScale. The JSON
output gains a transitionSamples field when the flag is on.

Fixes #1380

* fix(cli): sample every transition boundary by default; cap only on explicit request

Review follow-up on #1386: the silent cap of 40 contradicted the flag's
promise - on a dense timeline the strided subset could skip the exact
short boundary window the mode exists to catch, with no indication that
samples were omitted.

--at-transitions now samples every collected boundary by default. The
cap only applies when the new --max-transition-samples flag is passed,
and when it truncates, the omitted count is reported both as a console
warning and as transitionSamplesDropped in the JSON output.

James RussoandClaude Opus 4.7 6affe2d212 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)

* 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.

* 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.

James Russo 2be41937a9 fix(cli): support arm64 hosts for --docker render (#1196) 
* fix(cli): support arm64 hosts for `--docker` render

The Docker render path pinned `--platform linux/amd64` for both build
and run, which on Apple Silicon / Graviton forced qemu emulation of
chrome-headless-shell. The emulated chrome process either SEGV'd or
hung on page navigation, producing the failures reported in #1193 /
#1194 / #1195.

Derive the platform from `process.arch` instead. On arm64 hosts:

- The image builds natively (no qemu).
- The Dockerfile skips the chrome-headless-shell install because
  Chrome for Testing only publishes a `linux64` build (verified
  against the known-good-versions manifest).
- The wrapper script leaves `PRODUCER_HEADLESS_SHELL_PATH` unset
  when no headless-shell binary is present, so the engine falls
  back to the system chromium that the Dockerfile already
  installs from apt and points at via `PUPPETEER_EXECUTABLE_PATH`.

`TARGETARCH` is forwarded as an explicit `--build-arg` instead of
relying on BuildKit's automatic platform args — the legacy
builder (and some BuildKit configs, including colima on macOS)
leaves it unset, which would silently bypass the arch conditional
in the Dockerfile.

Image tags are now suffixed with `-arm64` on arm64 hosts so amd64
and arm64 images of the same hyperframes version can coexist in
the local cache.

The arm64 path renders correctly but loses byte-for-byte parity
with amd64 (system chromium uses screenshot capture, not
HeadlessExperimental.beginFrame). The CLI prints a one-line
warning so users comparing against amd64 baselines know.

Verified on macOS 26.5 / M4 Max:

- Before: `qemu: unknown option 'type=gpu-process'` followed by a
  chrome-headless-shell SIGSEGV after ~4 minutes.
- After: 300/300 frames captured in ~18s of render time (1m18s
  wallclock including a one-time image build), MP4 produced.

Closes #1193
Closes #1194
Closes #1195

* fix(cli): address review feedback on docker arm64 fix

Follow-up to 61880cdc. Addresses one substantive review comment from
@vanceingalls and three self-review gaps.

1. Restore loud build failure on amd64 when chrome-headless-shell is
   missing (per @vanceingalls). The original Dockerfile used an `&&`
   chain that crashed the build if `find` returned empty; the new
   `if/else` wrapper silently fell through to system chromium even on
   amd64, which would mask golden-baseline regressions from a future
   @puppeteer/browsers cache layout change. The else branch now checks
   `TARGETARCH = amd64` and exits 1 with an actionable error, while
   arm64 still falls through to the system-chromium wrapper cleanly.

2. Add `HYPERFRAMES_DOCKER_PLATFORM` env override. The fix derives
   platform from `process.arch`, which silently picks the wrong arch
   in three real-world cases: x64 Node under Rosetta on Apple Silicon
   (re-triggers issue #1193), parity-regen for amd64 golden baselines
   on an arm64 host, and DOCKER_HOST pointing at a remote daemon with
   a different arch. Empty/whitespace override is a no-op (falls back
   to arch detection) so `export FOO=""` doesn't pin platform to "".

3. Fail fast when `--gpu` is requested on arm64. Docker Desktop on
   Apple Silicon doesn't implement `--gpus` passthrough; the previous
   code would crash at `docker run` with an opaque device-driver
   error. We now short-circuit with errorBox pointing at the env
   override as the workaround.

4. Close the test gap on the default-arch resolution. Every previous
   test passed `arch` explicitly; a refactor that dropped the
   `= process.arch` default would pass all tests but break every arm64
   host at runtime. Added one assertion that calls
   `resolveDockerPlatform()` with no args, plus coverage for the env
   override.

The new arm64 platform-checking logic is extracted into
`resolveDockerHostPlatform()` so `renderDocker` itself stays focused
on the build/run wiring (and below the fallow complexity gate).

Test plan:
- `bunx vitest run packages/cli/src/utils/dockerRunArgs.test.ts` — 31 passed (was 27).
- `bunx vitest run packages/cli` — 647 passed (was 643).
- E2E on macOS 26.5 / M4 Max: deleted the cached arm64 image, ran
  `--docker --quality draft --workers 1` against the blank scaffold —
  300/300 frames in 1m1s wallclock, MP4 produced.

Miguel Ángel a4706da513 fix(cli): localize external assets in publish archive (#1160) 
Compositions referencing assets outside the project directory (via ../
paths) produced broken published projects — those files were never
included in the ZIP archive.

localizeExternalAssets() now scans all HTML and CSS files in the archive
for src, href, and url() references that resolve outside the project
dir. For each, it copies the file into the archive under _ext/ and
rewrites the reference to point there.

Handles: src/href attributes, <style> url(), inline style url(),
standalone CSS url(), sub-composition HTML files, deduplication of
the same asset referenced from multiple files.

Shared primitives (CSS_URL_RE, isNonRelativeUrl, isPathInside) extracted
into core/compiler/assetPaths.ts — single source of truth across core,
producer, and CLI.

Miguel Ángel fb2e21090f feat(studio): GSAP tween editing in Design panel (#1102) 
* feat(studio): GSAP tween editing in Design panel

Add a GSAP animation editor to the studio Design panel: select an element,
view and edit its tweens (properties, easing, timing), add/delete animations,
and drag custom bezier speed curves — all persisted back to the composition
HTML. Gated behind VITE_STUDIO_ENABLE_GSAP_PANEL.

Parsing of existing GSAP source now uses a recast + Babel AST parser instead of
regex, giving scope resolution, stable tween IDs, and round-trip preservation of
extras and unresolved raw values.

recast compiles to CommonJS that calls require("fs"), which breaks browser and
Vite SSR bundles. To contain it, @hyperframes/core is split into an isomorphic
layer and a Node-only AST layer:

- gsapSerialize.ts holds the recast-free helpers (serialization, keyframe
  conversion, validation, shared types). htmlParser.ts is now fully isomorphic.
- parseGsapScript and the script-mutation helpers live in gsapParser.ts,
  reachable only via the @hyperframes/core/gsap-parser subpath, loaded
  server-side by the studio-api mutation routes and the linter via dynamic
  import (recast stays external under SSR).
- The barrel and the gsap-constants subpath are recast-free, so studio browser
  bundles never trace recast.

Adds AST parser unit + stress coverage and e2e helpers for the panel.

Miguel Ángel d83a873986 fix(producer): normalize error messages to prevent [object Object] in telemetry (#1099) 
* fix(producer): normalize error messages to prevent [object Object] in telemetry

When a render fails and the caught value is a plain object (not an Error
instance), String(error) produces [object Object], masking the real error
in PostHog telemetry (~24 errors/day).

Add normalizeErrorMessage() that tries Error.message, string passthrough,
.message on plain objects, JSON.stringify, and String() as a last resort.
Apply it on the two telemetry-feeding paths: the main render failure
handler (renderOrchestrator.ts:2099) and buildRenderErrorDetails
(cleanup.ts), plus the error classifier isRecoverableParallelCaptureError
so timeout detection works even when the thrown value is a plain object.

* fix: address review — normalize CLI telemetry path, captureCost fallback

* fix: use local normalizeErrorMessage in CLI to avoid cross-package resolution

The Vite test runner can't resolve runtime imports from @hyperframes/producer
since its exports point to dist/. Copy the utility into the CLI package and
import locally instead.

AnoKno 0ea8aa4ffa fix(cli): address PR #983 review feedback 
- play.ts: move --remote-debugging-port parse+deps validation before any
  server setup so an invalid value exits cleanly instead of leaking a
  listening socket (the original bug — server printed 'Player running'
  and 'Press Ctrl+C to stop' before failing).
- Extract validateRemoteDebuggingPortDeps() in openBrowser.ts to keep
  preview.ts and play.ts in sync instead of copy-pasting the dep
  checks.
- Narrow parseRemoteDebuggingPort param to string | undefined; drop the
  dead null branch and the redundant String() / Number.isInteger() now
  that the regex already constrains the input.
- buildBrowserArgs: omit --remote-debugging-port when userDataDir is
  missing so a CDP endpoint cannot leak into the user's main profile
  even if a caller bypasses the CLI validation layer.
- Replace the duplicated buildBrowserArgs case with one that proves
  this defense-in-depth behaviour; add unit tests for
  validateRemoteDebuggingPortDeps.
- Drop the heavy JSDoc on parseRemoteDebuggingPort to match the file's
  surrounding style.
- Both commands: align --remote-debugging-port description (it now
  matches the actual 'requires --browser-path and --user-data-dir'
  contract) and add a CDP example to the --help output.

Miguel Ángel 84edce908a fix: address code review feedback on process cleanup

- Reorder cleanup: killTrackedProcesses() (sync, fast) runs first,
  then async browser drain. Ffmpeg dies immediately instead of
  surviving if the hard timer fires early.
- SIGKILL escalation: processTracker now SIGTERMs all tracked
  processes, then SIGKILLs survivors after 500ms grace period.
- Scope pgrep to current user (pgrep -u $(id -u)) so orphan
  detection doesn't touch other users' Chrome on shared machines.
- Add process.on('exit') handler for crash paths (unhandled
  exceptions/rejections that bypass signal handlers).
- Document Windows no-op behavior on killProcessTree handlers.

Miguel Ángel a54953b936 fix: clean up orphaned Chrome and ffmpeg processes on preview exit 
The preview command's shutdown handler only closed the HTTP server,
leaving Chrome (browser pool) and ffmpeg processes alive. This caused
silent resource leaks — orphaned processes consuming CPU and RAM with
no parent.

Root cause: preview.ts never called drainBrowserPool() or killed
tracked ffmpeg processes. The thumbnail browser in studioServer.ts
registered its own competing signal handlers that raced with
preview's shutdown.

Fix:
- Add a central process tracker (processTracker.ts) that registers
  every spawned ffmpeg across engine and producer packages
- Centralize thumbnail browser cleanup via exported
  closeThumbnailBrowser() instead of scattered signal handlers
- Wire preview shutdown to call closeThumbnailBrowser(),
  drainBrowserPool(), and killTrackedProcesses() before closing the
  HTTP server (embedded mode)
- Add killProcessTree() for dev/local modes where Chrome runs in a
  child process tree
- Add startup orphan detection that finds and kills orphaned
  chrome-headless-shell/Puppeteer Chrome processes (PPID=1) from
  previously crashed sessions

JamesandClaude Opus 4.7 ec1b7e1eff feat(cli): warn when lambda --width/--height conflicts with composition 
`--width 3840 --height 2160` against a composition with
`data-width="1920"` silently produces a 1080p output because the
runtime lays out the page at the composition's authored dimensions —
real footgun we hit during a cost-analysis sweep. Warn early and point
at `--output-resolution` (the supersampling escape hatch) so the user
doesn't burn a 30-minute render learning the override rule.

Skipped when `--output-resolution` is set (the supported supersampling
path — the user is opting in), when `--json` is set (machine consumers),
or when `index.html` isn't on disk (typical with `--site-id`).

Helper lives in a shared module so render + render-batch agree on the
parse + message. Tests cover both attribute orders, single/double
quotes, the silent paths, and the warning path. Best-effort regex over
the canonical attr shape — malformed HTML falls through to no warning
rather than blocking the render.

James cb948d5fcf feat(cli): hyperframes lambda render --variables / --variables-file / --strict-variables 
Mirror the local hyperframes render variables UX on the Lambda CLI:

- --variables '<json>'       inline JSON object of variable values
- --variables-file <path>    path to a JSON file with variable values
- --strict-variables          fail on type/declared-mismatch (warn by default)

Resolution + validation logic is hoisted to packages/cli/src/utils/variables.ts
so both surfaces share one parser. The new reportVariableIssues helper formats
the warning block + handles --strict-variables exit, deduping the per-CLI
issue-handling block.

Variables flow into SerializableDistributedRenderConfig.variables and reach
every chunk worker via the path PR 9.1 + 9.2 wired up (plan() →
meta/encoder.json → renderChunk() → window.__hfVariables). Pre-validation
against the composition's data-composition-variables declaration runs only
when the project's index.html is on disk — --site-id pointing at a
pre-uploaded site that was packaged elsewhere skips the check, matching how
the local CLI treats unreadable index files.

The render.ts re-exports of parseVariablesArg / resolveVariablesArg /
validateVariablesAgainstProject are dropped; the matching tests move to
packages/cli/src/utils/variables.test.ts where the implementations now live.

Docs: docs/packages/cli.mdx adds a section on --variables / --variables-file /
--strict-variables for lambda render, including the 256 KiB Step Functions
execution-input cap and a pointer to the upcoming templates-on-lambda guide
(PR 9.5).

James 7e0a447325 refactor: drop unused exports detected by fallow auto-fix 
Run `fallow fix --auto-fixable` to remove `export` keywords from symbols
fallow's reachability analysis identifies as unused. Keeps only the cases
where the symbol is still referenced internally in its own file (so
removing `export` doesn't surface a new oxlint `no-unused-vars` error).

Result: fallow dead-code findings drop from 276 → 208 (68 fewer unused
exports), with no behavior change — each symbol is still defined and used
exactly the same way within its file.

Reverted ~20 files where fallow's auto-fix would have created cascading
"declared but never used" lint errors — those are cases where the symbol
isn't used at all, and properly cleaning them up means deleting the
declaration, not just dropping `export`. Better to land that as a
separate, narrower PR rather than mixing it into a mechanical de-export.

Also reverted four false positives where fallow missed real consumers:
- `captureCost.ts` (renderOrchestrator has two separate import blocks
  from the same module; fallow only saw the first)
- `propertyPanelHelpers.ts`, `domEditingLayers.ts` (real internal uses
  fallow's reachability missed)
- `render.ts` (functions imported via `await import()` dynamic import,
  which fallow's static analysis doesn't follow)

Test plan: bun run --filter '*' typecheck (clean), oxlint + oxfmt clean,
cli/core/studio/engine vitest suites pass (335 + 917 + 576 + 605 tests).

James 2087d5dab2 chore: add fallow config and fix high-signal findings 
Configure fallow via .fallowrc.jsonc so its analysis reflects this repo's
real entry surface, then fix the genuine issues it found.

Fallow noise reduction (601 → 276 dead-code findings):
- Ignore docs/, test fixtures, skill test-corpora, registry/, examples/
- Declare worker entry points loaded dynamically by file path
  (pngDecodeBlitWorker.ts, shaderTransitionWorker.ts)
- Declare runtime IIFE entry (core/src/runtime/entry.ts) built outside the
  import graph by build-hyperframes-runtime-artifact.ts
- Declare bun:test files in producer + aws-lambda as test entries
- Ignore dynamically-resolved deps: tsup external (puppeteer-core, esbuild,
  giget), peer/static-file (gsap in player perf tests), workspace deps
  hoisted by bun (happy-dom, @hyperframes/*), and @fontsource/* packages
  read via readFileSync in generate-font-data.ts

Extract inline build:fonts scripts:
- packages/{cli,producer}/package.json had multi-line `node -e ...` blobs
  containing braces that fallow mis-parsed as glob alternate groups. Moved
  to dedicated build-fonts.mjs scripts.

Fix duplicate exports:
- Remove dead FileIcon alias in studio/SystemIcons.tsx (FileTreeIcons.tsx
  has the real, used one)
- Consolidate ValidationResult: drop the identical duplicate in
  gsapParser.ts; both parsers now import from core.types
- Suppress intentional namespace patterns (per-namespace ML manager
  exports; CLI per-command 'examples' convention; fileServer.ts test-only
  isPathInside which has different symlink semantics from utils/paths.ts)

Break circular dep (studio/components/editor):
- manualEditsDom.ts re-exported clearStudioPathOffset / clearStudioRotation
  / clearStudioBoxSize from manualEditsSnapshot.ts, which imports four
  helpers from manualEditsDom.ts — back-edge cycle
- Re-export moved to manualEdits.ts (the package-public barrel) where the
  rest of the snapshot re-exports already live; underlying files now form
  a clean DAG

Remove genuinely unused deps:
- studio: motion (no imports anywhere), codemirror (umbrella package; the
  @codemirror/* sub-packages are used directly)
- cli: mime-types (plus its only consumer src/utils/mime.ts, which was a
  hardcoded mime table that didn't use the package), and its now-stale
  tsup external entry

Verified: typecheck across core/cli/producer/studio is clean, oxlint
+ oxfmt pass, manualEdits.test.ts (18 tests) and core parser tests (69
tests) still pass.

Deferred follow-ups (real findings, separate PRs):
- 8 circular deps in producer/services/render/stages/ — renderOrchestrator
  ↔ captureHdr* / captureStage / extractVideosStage form a hub cycle
- ~14 unused files in producer/src/services/ that look like dead
  re-export shims to @hyperframes/engine, but aren't in the public
  exports map — need to confirm no deep-import consumers before deletion
- waveform.ts complexity hotspot

 		f84cc492de 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.

* 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.

* 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.

Perf: 15-scene shader-perf fixture (28s, 14 transitions, 30fps)
  Baseline (Node-side layered): 137s
  Page-side (html2canvas+WebGL): 33s → 4.1× speedup

* fix(producer): unify page-side compositing gating and Docker forwarding

Addresses three issues from staff review:

1. ignoreElements filter stripped all in-scene canvases (Chart.js, D3,
   p5.js) — narrowed to data-no-capture only since the compositor canvas
   is a body sibling never in the scene subtree.

2. 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.

* 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.

Perf: 15-scene fixture (28s, 14 transitions, 30fps):
  Baseline (Node-side layered): 137s
  html2canvas + WebGL:           33s (3.7×)
  drawElementImage + WebGL:      21s (6.6×)

  round-trip per frame (~700 unnecessary IPC calls on non-transition

* feat(engine): default-on page-side compositing for SDR shader transitions

Page-side compositing is now enabled by default for SDR shader-transition
renders without video content. The 6.6× speedup applies automatically —
no flag needed.

Auto-disables when:
- HDR content detected
- Alpha output (WebM/MOV/PNG-sequence)
- Composition contains <video> elements (cloneNode loses playback state)
- beginFrame capture mode (Linux headless)

Use --no-page-side-compositing to force the Node-side layered path.

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

* 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.

* fix(core): auto-inject data-start on video/audio so frame extraction works without explicit attrs

The timing compiler now injects data-start="0" on <video> and <audio>
elements that lack it. This makes discoverMediaFromBrowser() find the
element (it queries video[data-start]), so the frame extraction pipeline
activates automatically. Videos "just work" without requiring authors to
add data-start, data-end, or id attributes.

Also removes the video_missing_timing_attrs lint rule — the compiler
handles the missing attributes automatically, so the lint rule would
only false-positive.

* feat(core): add data-hf-auto-start sentinel on auto-injected video timing

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat(producer): add discoverVideoVisibilityFromTimeline for runtime video discovery

Seeks the GSAP timeline in Puppeteer to discover when each video's parent
scene is visible (opacity > 0). Uses coarse sampling at 100ms steps followed
by binary search refinement to frame-level precision (1/60s). Only processes
videos with the data-hf-auto-start sentinel so author-specified timing is
never overridden.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(producer): trigger browser probe for auto-start videos, remove debug logging

The probe stage was skipping browser launch when composition duration was
already known, which meant discoverVideoVisibilityFromTimeline never ran.
Now needsBrowser also checks for data-hf-auto-start sentinel in compiled HTML.

Theodor Kleynhans 5dcc89c930 feat(cli): accept ffmpeg-style rational fps (NTSC, PAL, slow-mo) 
Replaces the rigid `--fps 24|30|60` whitelist with a numeric range and
adds support for ffmpeg-style fractional framerates so NTSC stays exact
end-to-end.

- `--fps 30` keeps working (integer fps)
- `--fps 30000/1001` now means exact NTSC 29.97 (not the lossy decimal)
- `--fps 24000/1001`, `--fps 60000/1001`, `--fps 25/50/120/240` all work
- Decimals like `--fps 29.97` are rejected with a friendly error pointing
  the user at the rational form, since `29.97` and `30000/1001` round
  to different framerates inside ffmpeg

Carries an `Fps = { num: number; den: number }` rational end-to-end:
RenderConfig, EncoderOptions, StreamingEncoderOptions, CaptureOptions,
DockerRenderOptions, Studio API request body, regression-harness
meta.json. The `-r` and `-framerate` ffmpeg args emit the rational form
verbatim (`30000/1001`) so no decimal round-trip happens at the encoder
boundary. Frame-interval math uses `1000 * den / num` ms (33.366… for
NTSC, 33.333… for integer 30).

Helpers live in @hyperframes/core:
- `parseFps(input: string | number): FpsParseResult` — discriminated
  parser used by both the CLI and the Studio API route
- `fpsToFfmpegArg(fps: Fps): string` — emits "30" or "30000/1001"
- `fpsToNumber(fps: Fps): number` — for arithmetic (telemetry, frame
  count, frame-index → time)

Studio API wire format accepts polymorphic `fps: number | string`:
- number → integer fps (`30`)
- string → rational (`"30000/1001"`)
Decimals are rejected; matches the same rule as the CLI.

Existing meta.json fixtures with integer `"fps": 30` continue to load
unchanged — the regression-harness validator now normalizes both number
and string inputs through `parseFps`.

Theodor Kleynhans 4e28658173 feat(cli): expose png-sequence format 
The producer already supports `format: "png-sequence"` end-to-end (see
RenderConfig in renderOrchestrator.ts), but the CLI's VALID_FORMAT
validator rejects it before the flag reaches the producer. Surface it
the same way `mov` and `webm` are surfaced.

Behaviour:
- `--format png-sequence` accepted alongside mp4/webm/mov.
- Auto-output path uses no extension (FORMAT_EXT["png-sequence"] = "")
  since the producer treats outputPath as a directory of frame_NNNNNN.png.
- `printRenderComplete` sums the contained file sizes when outputPath
  is a directory, instead of reporting the platform-dependent inode
  size.
- DockerRenderOptions.format type extended; existing buildDockerRunArgs
  is unchanged because it forwards the string verbatim.

Tests:
- renderLocal forwards `format: "png-sequence"` to createRenderJob.
- buildDockerRunArgs propagates `--format png-sequence` to the
  container.

Docs:
- Rendering guide: format flag table, format comparison table, new
  "PNG sequence (no encoding)" section, "How it works" extended.
- CLI package docs: format flag table updated.

Miguel Ángel 0e0a0e40d0 feat(cli): add --composition flag to render specific compositions (#631) 
* feat(cli): add --composition flag to render specific compositions

Expose the existing entryFile config in the producer through
a new --composition / -c CLI flag. This lets users render
individual composition files without restructuring their project:

  hyperframes render -c compositions/intro.html -o intro.mp4

The flag validates the file exists before starting the render,
threads through both local and Docker render paths, and is
documented in the CLI help, examples, and docs.

* fix(cli): address PR review — path traversal guard, forward tests, tripwire

- Add path-containment check mirroring hyperframeLint.ts: reject
  --composition paths that escape the project directory
- Normalize leading ./ from composition paths for clean render plan output
- Improve error message: suggest .html file path instead of compositions command
- Add description note about <template> sub-composition constraint
- Add render.test.ts: entryFile forwarded to createRenderJob (forward + omit)
- Update dockerRunArgs tripwire test with entryFile coverage

Miguel Ángel 21ec5f800a fix(cli): use size-adaptive timeouts for publish uploads (#635) 
## Summary
- Replace the flat 30s upload timeout with a size-adaptive calculation: `max(120s, bytes / 500KB/s)`
- Metadata requests (presigned URL, complete) keep the original 30s timeout
- Companion to the backend change removing the 64 MB upload limit in experiment-framework

## Context
With the backend size limit removed, large projects (78 MB+) need proportionally longer to upload. A 78 MB project now gets ~164s, a 500 MB project ~17 min. The old 30s timeout would abort any upload over ~15 MB on a typical connection.

## Test plan
- [x] All 4 existing vitest tests pass
- [x] Build succeeds, no type errors
- [x] Lint + format pass (oxlint + oxfmt)
- [x] Timeout values verified for 10/78/200/500/1000 MB archives

JamesandClaude Opus 4.7 c0d75a5268 feat(core,cli,engine,producer): add getVariables() helper and --variables render flag 
Adds the parametrized-render primitive from hf#592 by reusing the existing
data-composition-variables schema as the source of declared defaults.

- Runtime helper window.__hyperframes.getVariables() (also exported from
  @hyperframes/core) reads data-composition-variables defaults from the
  document root and merges window.__hfVariables (CLI override) on top.
  Returns Partial<T> for typed access; supports a generic for editor
  ergonomics. Same code path runs in dev preview and at render time.
- CLI render --variables '<json>' / --variables-file <path> populates the
  override. Mutually exclusive; fail-fast on conflicting flags, missing
  file, unparseable JSON, or non-object payloads. parseVariablesArg is
  exported as a pure function so validation paths stay unit-testable.
- Engine injects window.__hfVariables via evaluateOnNewDocument before
  any page script runs, so the helper sees the merged values on its
  first call. Empty payloads are skipped to avoid pointless init scripts.
- Producer threads variables through RenderConfig and into the engine's
  CaptureOptions; Docker mode forwards --variables to the in-container
  CLI invocation via dockerRunArgs.

Composition authors declare variables once on the root <html> element:

  <html data-composition-variables='[
    {"id":"title","type":"string","label":"Title","default":"Hello"}
  ]'>

and read them in any composition script:

  const { title } = window.__hyperframes.getVariables();

A render with `--variables '{"title":"Q4 Report"}'` overrides the default
without modifying the composition source. Missing keys fall through to
the declared defaults, so dev preview and CLI renders without --variables
behave identically.

This is PR 1 of a 4-PR stack. Sub-comp per-instance scoping (carrying
host data-variable-values through the inlined sub-comp's getVariables()
call) lands in PR 2; schema validation and lint in PR 3; skill / scaffold
distribution in PR 4.

Tests: 9 new unit tests for getVariables() (jsdom), 11 new CLI tests
covering parseVariablesArg validation paths and Docker passthrough,
2 new dockerRunArgs assertions for the --variables flag. All existing
tests green (core 611, cli 208, engine 519).

Miguel Ángel 15ee63c6e7 fix: harden CLI edge-case repros (#591) 
## Problem

I reproduced the selected open issue batch one by one and confirmed the reports were valid. The fixes all touch the CLI/runtime capture boundary, then the follow-up regression run exposed one over-broad runtime change in sub-composition host visibility and one CI-only baseline trap.

Closes #590, #589, #588, #587, #586, and #584.

## What this fixes

### CLI/runtime edge cases

- Makes the GSAP infinite-repeat lint rule ignore JavaScript comments, so literal `repeat:-1` text in comments is not flagged.
- Lets the compositions CLI inspect `<template>` content, count visual-only template descendants, estimate simple GSAP durations, and suppress root `data-start` warnings in sub-composition lint mode.
- Preserves runtime bootstrap scripts when body scripts are coalesced, and injects the runtime into a real `<head>` when source HTML has no head.
- Keeps #589 fixed by loading and rendering template-wrapped sub-composition content, while restoring host visibility to the shorter of the authored parent clip window and the child composition live timeline.
- Resolves snapshot/validate viewport size from root `data-width` / `data-height` instead of falling back to 1920x1080.
- Skips fully off-frame text boxes during contrast sampling and bounds-checks ring samples so contrast output no longer emits `null:1` / `NaN:1`.
- Marks muted videos as `data-has-audio="false"` in the core timing compiler, which fixes the same-src muted `<video>` + separate `<audio>` StaticGuard case.
- Keeps user-authored `hf-seek` listeners reachable during capture by preventing author scripts from being merged into the runtime bootstrap path.

### Shared helper cleanup

- Removes the stale producer-local timing compiler duplicate; producer compilation now consumes the core timing compiler.
- Centralizes HTML document helpers in core: fragment parsing, embedded runtime stripping, head/body script injection, and early-head injection.
- Centralizes the CLI layout/snapshot static HTML server.
- Adds browser-safe core subpath helpers for Lottie readiness and CLI screenshot clip calculation; Studio's Vite config keeps the screenshot clip helper self-contained so clean-checkout test startup does not value-import core `.ts` source.
- Replaces the engine parity-contract copy with a core re-export.
- De-duplicates render-job cleanup and Studio static file-serving callbacks.

### Regression hardening

- Replaces the embedded-runtime script stripping regex with a script-tag scanner that handles closing tags like `</script >`.
- Escapes inline script bodies before wrapping them in `<script>` tags, so authored `</script` and `<!--` text cannot break out of the injected wrapper script.
- Shares media-duration clamping between core and producer, with a 50 ms tolerance for ffprobe precision drift between local and CI media stacks.
- Pins the affected style fixture SFX durations in source so style-1 and style-9 compile deterministically.
- Restores the `vfr-screen-recording` video golden to the CI-stable baseline; the current CI failure showed the Linux render matches the old golden, while the locally refreshed macOS golden was the mismatch.

## Root cause

The CLI paths had accumulated assumptions that held for simple direct-root landscape compositions but not for current composition patterns: DOM queries did not enter template content, snapshot/validate used a fixed viewport, runtime and author scripts shared a coalescing bucket, and timing compilation treated every video as audio-bearing unless authors manually overrode it.

The style shard failures were not product regressions. Local and CI media probing disagreed on the short SFX clip duration by about 45 ms, and the compiler was clamping authored durations to the locally probed value. The shared clamp tolerance preserves explicit author/source durations for small probe precision differences while still clamping real overflows.

The vfr fast-shard failure was a bad baseline refresh: CI actual frames matched the old `vfr-screen-recording` baseline at 40+ dB PSNR, but mismatched the macOS-refreshed golden at ~18-22 dB. The fix is to keep the Docker/Linux-stable video golden and only retain the deterministic compiled snapshot change.

The sub-composition regression came from treating a host's authored parent window as the only visibility boundary. That made settled child overlays stay visible after their own live GSAP timeline ended. The corrected runtime behavior respects both contracts: parent clips still bound where the host can appear, and the child live timeline can end the host earlier.

### CI artifact checks

- Inspected failed run `25225854394` job `73969147096`: style-1 failed only on `click-sfx` `1.044898` vs `1` duration/end.
- Inspected failed run `25225854394` job `73969147061`: style-9 failed only on SFX `1.044898`-based duration/end mismatches.
- Inspected failed run `25225854394` job `73969147048`: `vfr-screen-recording` compilation/audio passed, visual failed after comparing against the macOS-refreshed golden.
- Compared the first 10 uploaded CI vfr failure frames against the restored old baseline; minimum PSNR was `40.444705`, above the fixture threshold of `28`.

### Repro checks

- `bun packages/cli/src/cli.ts lint /tmp/hf-590-repro` now passes without `gsap_infinite_repeat`.
- `bun packages/cli/src/cli.ts snapshot /tmp/hf-587-repro --at 0.5 --timeout 1000` now writes a 1080x1920 PNG.
- `bun packages/cli/src/cli.ts validate /tmp/hf-588-repro --timeout 500` no longer emits `null:1` / `NaN:1` contrast output.
- `bun packages/cli/src/cli.ts validate /tmp/hf-586-repro --timeout 500 --contrast false` no longer emits the muted-video StaticGuard contract error.
- `bun packages/cli/src/cli.ts compositions /tmp/hf-589-gsap-repro` now reports `foo 0.5s 1920x1080 1 element`.
- `bun packages/cli/src/cli.ts snapshot /tmp/hf-589-gsap-repro --at 0.25 --timeout 2000` captures the expected template-backed red frame.
- `bun packages/cli/src/cli.ts snapshot /tmp/hf-584-repro --at 0.5,1.5 --timeout 500` captures the expected post-seek green frame.

### Browser verification

- Refreshed the local side-by-side comparison page at `qa-artifacts/pr-591-video-compare/index.html`.
- Served the comparison page locally and used `agent-browser` to load `style-12-prod`, play both videos quickly to the failed window, pause, and inspect the side-by-side frame.
- Browser proof screenshot: `qa-artifacts/pr-591-video-compare/browser-proof/fixed-style12-labeled.png`.
- Browser proof recording: `qa-artifacts/pr-591-video-compare/browser-proof/fixed-style12.webm`.
- Earlier Studio proof artifacts remain local-only: `qa-artifacts/dedupe-refactor-preview.png`, `qa-artifacts/dedupe-refactor-preview-after-play.png`, `qa-artifacts/dedupe-refactor-preview.webm`.

## Notes

- Browser proof and CI diagnostic artifacts are intentionally local-only and not committed.
- Studio's Vite config intentionally keeps the thumbnail clip helper inline because Vite/Vitest config startup runs through Node's loader before package source `.ts` imports are transformed.
- The committed PR diff changes `vfr-screen-recording/output/compiled.html` but no longer changes `vfr-screen-recording/output/output.mp4` relative to `main`.
- I attempted a local `linux/amd64` Docker validation to mirror CI, but the local Docker build was blocked by Debian package download failures. The arm64 Docker image also cannot launch the x64 Puppeteer headless shell under OrbStack. The vfr baseline decision is therefore based on the uploaded CI artifact comparison above.
- I kept this validated issue batch in one PR because the fixes overlap the same CLI/runtime capture surfaces.

Miguel Ángel 395fb9c084 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.

### 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.

Vance IngallsandClaude Opus 4.6 8e5593b6ba feat(render): auto-detect HDR from media probes, add --sdr flag (#526) 
* feat(render): auto-detect HDR from media probes, add --sdr flag

Replace the --hdr opt-in model with automatic detection. When no flags
are passed, the renderer probes all video/image sources and enables HDR
output if any HDR color space is detected. Existing --hdr flag becomes
a force override. New --sdr flag forces SDR output.

Behavior matrix:
  (no flags) + HDR content → HDR output
  (no flags) + SDR content → SDR output
  --hdr → force HDR (defaults to HLG if no HDR sources)
  --sdr → force SDR (skips probing)
  --hdr --sdr → error

Mu-Tsun Tsai 1782cebfc4 fix(cli): resolve sub-composition <audio> src relative to its own file (#489) 
`lintAudioSrcNotFound` resolves every `<audio src>` against the project
root, which is correct for index.html but wrong for sub-compositions —
their srcs are written relative to the sub-composition file (e.g.
`../assets/foo.mp3`), and the bundler rewrites them at compile time.

Carry the sub-composition path alongside each html source and run
`<audio src>` strings starting with `../` through the existing
`rewriteAssetPath` helper before checking existence on disk. Mirrors the
runtime/bundler behaviour so the lint check sees the same path the
renderer will fetch.

Original (un-rewritten) src is still surfaced in the finding message so
authors can grep for it in their HTML.

Miguel Ángel b4e9d64e29 feat(cli): hyperframes publish — share projects via a public URL (#312) 
## Summary

This PR adds `hyperframes publish` as the OSS handoff into the persisted HyperFrames publish flow.

Instead of opening a local tunnel, the CLI now:

1. zips the local project
2. uploads it to the HeyGen publish backend
3. gets back a stable `hyperframes.dev` project URL plus claim token
4. prints a claimable URL for the user

Example output:

```bash
$ hyperframes publish

  Project    my-video
  Files      12
  Public     https://hyperframes.dev/p/hfp_123?claim_token=...

  Open the URL on hyperframes.dev to claim the project and continue editing.
```

## User Flow

The intended user flow is:

1. Run `hyperframes publish` from a local HyperFrames project.
2. The CLI uploads the project as a zip to the publish API.
3. The CLI prints a stable `hyperframes.dev` URL with the claim token attached.
4. The user opens that URL in the browser.
5. `hyperframes.dev` uses that URL to claim the published project and import it into the web app.
6. The user continues editing from a normal web session.

So the CLI is only responsible for packaging, upload, and printing the URL. The browser-side claim/import flow lives in the backend and web app stack.

## Routing

This PR does not expose a separate user-facing canary mode.

The CLI posts to the normal publish API host:
- `https://api2.heygen.com/v1/hyperframes/projects/publish`

Backend routing behavior is handled server-side. If the default path routes through canary, it does so without a dedicated CLI flag; if that path is unavailable, traffic falls back to prod behavior on the backend side.

## What Changed

| File | Role |
|---|---|
| `packages/cli/src/commands/publish.ts` | Adds the `hyperframes publish` command, confirmation prompt, lint-before-upload behavior, and user-facing output. |
| `packages/cli/src/utils/publishProject.ts` | Zips the local project, filters ignored files/directories, posts the archive to the publish API, and returns the published project metadata. |
| `packages/cli/src/utils/publishProject.test.ts` | Covers archive creation and successful upload response parsing. |
| `packages/cli/src/cli.ts` | Registers the new `publish` command. |
| `packages/cli/src/help.ts` | Adds `publish` to root help and examples. |
| `docs/packages/cli.mdx` | Documents the persisted publish flow. |

## Important Behavior

- Requires `index.html` at the project root.
- Ignores hidden files and common non-project directories like `.git`, `node_modules`, `dist`, `.next`, and `coverage`.
- Lints the project before upload and prints findings, but does not block publish on warnings.
- Does **not** keep a local process alive after upload.
- Does **not** open a public tunnel.
- Does **not** require HeyGen OAuth inside the CLI.

## Why This Shape

This keeps the OSS CLI simple and matches the current product direction:

- project persistence lives in HeyGen's backend
- the public URL comes from the persisted project row
- claiming/importing happens on `hyperframes.dev`
- the CLI should not own browser auth or long-lived sharing infrastructure

## Verification

In the earlier PR worktree, this flow was verified locally with the CLI build/test path and with real backend integration.

In this cleanup worktree, the narrow code/doc change was verified by inspection, but the repo-level commands are currently blocked here by missing local tool binaries and typings in the worktree environment:

- `bun run --filter @hyperframes/cli test` -> `vitest: command not found`
- `bun run --filter @hyperframes/cli typecheck` -> local dependency/type resolution failures outside this diff
- `bun run --filter @hyperframes/cli build` -> `tsx: command not found`

## Notes

This PR only covers the OSS CLI side of the flow.

The full end-to-end experience depends on the corresponding backend and `hyperframes.dev` changes that store published projects, return the stable URL, and support claim/import in the web app.

Miguel Ángel 5db554c7b6 feat(cli): silent auto-update on next run (#306) 
## Summary

Today users have to run `hyperframes upgrade` (or the right install command for their package manager) to get a new release — we ship fixes but they don't reach the install until the user remembers. This PR borrows the Claude Code model: detect the update on run N, install it in a detached background child, surface one line ("hyperframes auto-updated to vX.Y.Z") on run N+1. The user's current command never blocks, never prompts, never sees an install stream.

## Flow across two runs

```
Run N     → checkForUpdate() sees latest > current → spawn detached
            child running `npm install -g hyperframes@X` (or bun /
            pnpm / brew equivalent). Parent exits immediately.
(between) → detached child installs, writes completedUpdate into
            ~/.hyperframes/config.json, clears pendingUpdate.
Run N+1   → reportCompletedUpdate() prints one line and clears the
            marker. User is on the new version.
```

## Installer detection

Walks `realpathSync(process.argv[1])` against each package manager's well-known global prefix. Wrong guesses are biased toward `skip` — we'd rather miss an auto-update than clobber a Homebrew install with npm.

| Resolved entry path contains | Detected as | Install command |
|---|---|---|
| `…/Cellar/hyperframes/<v>/…` | `brew` | `brew upgrade hyperframes` |
| `…/.bun/…` | `bun` | `bun add -g hyperframes@<v>` |
| `…/pnpm/global/…` or `…/.pnpm/…` | `pnpm` | `pnpm add -g hyperframes@<v>` |
| `…/lib/node_modules/hyperframes/…` | `npm` | `npm install -g hyperframes@<v>` |
| `…/packages/cli/…` (workspace link) | `skip` | (no-op) |
| `…/_npx/…`, `…/bunx-…/…` | `skip` | (no-op) |
| Anything else | `skip` | (no-op) |

## Guardrails

- **Never auto-update across a major version.** The existing banner still nudges the user to run `hyperframes upgrade` explicitly.
- **Skip on CI, non-TTY, dev mode,** npx / bunx / workspace link, or any install layout the detector doesn't recognize.
- **`HYPERFRAMES_NO_AUTO_INSTALL=1`** disables the install without silencing the notice banner.
- **`HYPERFRAMES_NO_UPDATE_CHECK=1`** silences both (existing knob).
- **Fresh pending install (<10 min old)** prevents re-launch on every invocation.
- **Installer stdout + stderr go to `~/.hyperframes/auto-update.log`** for postmortem — the terminal stays clean.
- **Failed installs are surfaced once** with a prompt to run `hyperframes upgrade` manually.

## What changed

| File | Role |
|---|---|
| `packages/cli/src/utils/installerDetection.ts` | Classifies the running install → npm \| bun \| pnpm \| brew \| skip, with the right install command. |
| `packages/cli/src/utils/autoUpdate.ts` | `scheduleBackgroundInstall` + `reportCompletedUpdate`. Spawns a detached `node -e "..."` child that runs the install and writes the outcome back to the config, then `unref()`s so the parent exits immediately. |
| `packages/cli/src/telemetry/config.ts` | `pendingUpdate` + `completedUpdate` fields on the config schema. |
| `packages/cli/src/cli.ts` | Wires `reportCompletedUpdate()` at startup and `scheduleBackgroundInstall()` after `checkForUpdate()` resolves. |

## Verification

### Unit tests — 19 / 19 pass (full CLI suite 115 / 115)

- `installerDetection.test.ts` — 9 cases, one per layout (workspace, npx, bunx, brew, bun, pnpm, npm, unknown, unresolved).
- `autoUpdate.test.ts` — 10 scheduling-policy cases:
  - Minor/patch → schedules + writes pendingUpdate
  - Major bump → **does not** schedule
  - Dev mode → skipped
  - `CI=1` → skipped
  - `HYPERFRAMES_NO_AUTO_INSTALL=1` → skipped
  - Unknown installer → skipped
  - Already-on-latest → skipped
  - Fresh pending install → de-duplicated
  - Stale pending install (>10 min) → supersedes
  - Previous run already completed this version → skipped

Unit tests mock `spawn` and the installer — they verify the **policy**, not the real detached-child path.

### Live end-to-end smoke test (on this Mac, real processes)

To validate the parts the unit tests can't — actual detached spawn, real config writeback, banner surfacing in a fresh subsequent process — I wired a smoke script that exercises the exact same code path `autoUpdate.ts` uses, but with `echo …` as the "install command" so nothing global gets touched.

**Steps exercised:**

1. Backed up the user's real `~/.hyperframes/config.json`.
2. Wrote a `pendingUpdate` marker for version `0.4.99` (like `scheduleBackgroundInstall` does).
3. Spawned the **exact same detached `node -e "..."` child** the real scheduler produces, with the install command replaced by `echo 'faux install for 0.4.99'`.
4. The parent `unref()`d and continued; 800 ms later the parent re-read `config.json`.
5. Ran `reportCompletedUpdate()` in a **fresh subprocess** (via `bunx tsx -e ...`) to match the real "Run N+1" conditions, capturing its stderr.
6. Asserted the marker was cleared.
7. Restored the original config on exit.

**Observed output:**

```
  [setup] Backed up config to /Users/miguel/.hyperframes/config.json.smoke-backup
  [setup] Wrote pendingUpdate for v0.4.99
  [spawn] Detached child pid=49469
  [after] completedUpdate = {"version":"0.4.99","ok":true,"finishedAt":"2026-04-17T17:26:50.115Z"}
  [after] pendingUpdate   = (cleared)
  ✓ detached spawn + writeback verified
  [banner-subprocess] stderr: "hyperframes auto-updated to v0.4.99"
  ✓ banner fired in fresh process + marker cleared

  ALL CHECKS PASSED ✓
  [cleanup] Config restored
```

**What this proves:**

| Claim | Evidence |
|---|---|
| Detached spawn works (doesn't block the parent) | `[spawn] pid=49469` logged, parent continued immediately |
| Detached child is process-independent | Parent exited its own work while child ran `exec(CMD)` |
| Child writes correct config shape | `completedUpdate = { version: "0.4.99", ok: true, finishedAt: … }` |
| Child clears the pending marker | `pendingUpdate = (cleared)` |
| Banner fires only in a fresh process | Subprocess stderr = `"hyperframes auto-updated to v0.4.99"` |
| Banner message format | Matches the copy in `autoUpdate.ts:reportCompletedUpdate` exactly |
| Marker clears after banner | Second file read shows `completedUpdate` absent |

Both the original test-plan checkboxes (fresh install, `HYPERFRAMES_NO_AUTO_INSTALL=1`, `CI=1`) are covered by either the unit-test suite or this smoke test — the scheduling-policy gates are unit-tested under `CI=true`, and the real detached-spawn path is smoke-tested above.

### What's still worth doing

- **Physical installer test on a real `npm i -g` / `brew` / `bun add -g` environment** — the smoke test above replaces the install command with `echo`, so we've never actually seen npm/bun/brew run the real command. That's the one remaining unknown. Worth one manual run on the maintainer's machine before cutting v0.4.4.

## Test plan

- [x] `bunx vitest run` on `packages/cli` — 115 / 115 pass (incl. 19 new)
- [x] `tsc --noEmit` clean
- [x] `tsup` build clean
- [x] **Live e2e smoke test** exercising the real detached spawn + config writeback + fresh-process banner (output above)
- [x] CI green on this branch (Typecheck, Test, Test: runtime contract, Build, Lint, Format)
- [ ] One manual run on a physical `npm i -g hyperframes@0.4.2` install to confirm the real `npm install -g hyperframes@0.4.3` command actually runs when `autoUpdate.ts` delegates to it (the smoke test stopped short of executing `npm`)

## Notes

- Independent of any version bump — ship whenever.
- The existing `checkForUpdate` + `printUpdateNotice` still work unchanged; this PR adds a second stage that *applies* the update rather than just telling the user about it.
- `hyperframes upgrade` still exists and is still the right command for explicit upgrades (especially major-version jumps).

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.

ularkim a77a6cbbf7 fix: double-audio bug + lint rules + docs guide + capture improvements 
Double-audio bug fix:
- scaffolding.ts: stop writing index.html in captures/ (root cause —
  runtime discovered scaffold + real index.html as two compositions)
- New lint rule: multiple_root_compositions — errors if >1 root HTML
- New lint rule: duplicate_audio_track — warns on overlapping audio

Capture improvements (from testing 30+ websites):
- Catalog runs BEFORE extractHtml (which mutates DOM — converts img src
  to data URLs). HeyKuba: 2 images → 78.
- networkidle2 instead of networkidle0 (unblocks SPAs with WebSockets)
- Lazy-load image wait, CSS background-image cataloging
- SVG naming from class/id/parent (not just aria-label)
- Gemini batch 5→20, pause 12s→2s, maxOutputTokens 300→500
- Asset descriptions sorted: captioned first

Docs:
- New guide: guides/website-to-video.mdx (full tutorial)
- CLI docs: added capture and snapshot commands
- docs.json: website-to-video in Guides nav

James RussoandClaude Opus 4.6 b23b0751da fix(player): parent-frame media playback for mobile (#266) 
* fix(player): parent-frame media playback for mobile

Mobile browsers block media.play() inside iframes when the user
gesture happened in the parent frame — postMessage doesn't transfer
user activation (per the User Activation v2 spec).

## Problem

The player renders compositions in a sandboxed iframe. When a user
taps play in the parent frame, the player sends a postMessage to the
iframe's runtime, which calls audio.play(). On mobile, this fails
silently because the iframe has no user activation context.

## Solution

The player now extracts ALL timed media elements (audio/video with
data-start) from the iframe's DOM (same-origin access), creates
parent-frame copies, and disables the iframe originals. On play(),
parentMedia.play() runs synchronously in the gesture call stack,
satisfying mobile autoplay policy.

### Generic media handling

- Finds all `audio[data-start], video[data-start]` in the iframe
- Creates a parent-frame copy for each (Audio or Video element)
- Preserves data-start offsets for correct seek positioning
- Strips data-start from iframe elements so the runtime ignores them
- Falls back to iframe media for cross-origin iframes

### `audio-src` attribute

Convenience for the common single-narration case. When set, the
player starts preloading audio immediately — before the iframe loads.
This eliminates the loading delay that caused jittery playback.

### No active sync

Both parent media and the GSAP timeline are real-time systems. When
started simultaneously, they naturally stay within ~10ms — no drift
correction needed. Active sync with coarse granularity (50ms polling)
caused MORE jitter than it prevented via repeated audio seeks.

## CI

- Added unified `test` job replacing separate per-package test jobs
- Added root `test` script: `bun run --filter '*' test`
- New packages with test scripts are automatically included
- Added happy-dom for player DOM tests

## Tests

- 10 new tests for parent-frame media: preloading, play, pause,
  seek, muted/rate sync, cleanup, attribute changes
- All 21 player tests pass

* fix(shader-transitions): pass CI when no test files exist

Add --passWithNoTests to vitest run so the unified test job
doesn't fail on packages that have a test script but no test
files yet.

* fix(cli): update tests for new id field and GSAP lint rule

- normalize.test.ts: loadTranscript now assigns id fields (w0, w1, etc.)
  to SRT/VTT results and empty string for words-json passthrough
- lintProject.test.ts: add GSAP CDN script to validHtml() fixture to
  satisfy the missing_gsap_script lint rule added in core

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(cli): add missing data-start/data-duration to validHtml fixture

The validHtml() test fixture was missing data-start and data-duration
attributes, triggering the root_composition_missing_data_start and
root_composition_missing_data_duration lint warnings.

* fix(ci): fetch LFS objects for producer test job

Producer regression tests compare rendered output against reference MP4
files stored in git LFS. Without lfs: true, checkout fetches pointer
files instead of actual videos, causing "moov atom not found" errors.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* ci: remove redundant test-producer job

The regression workflow already runs the same 28 producer fixtures
in a Docker container with prod-matching Chrome/fonts/ffmpeg, sharded
across 8 parallel matrix jobs with 40-min timeouts. The CI test-producer
job was a duplicate that ran on bare runners with worse determinism
and a 15-min timeout too short for all fixtures.

James Russo 08fb1de61f feat(cli): add command + hyperframes.json (#256) 
## What

PR 5/17 of the catalog system rollout. Adds the `hyperframes add` verb for installing blocks and components from the registry into an existing project, plus the `hyperframes.json` project config that tells `add` which registry to use and where to drop files. Stacks on #255.

- **`packages/cli/src/commands/add.ts`** — new `hyperframes add <name>` command. Resolves an item, validates target paths, installs files in parallel, builds an include snippet, copies it to the clipboard. Exposes a testable `runAdd(opts)` function; the citty default wraps it with console output + exit handling
- **`packages/cli/src/utils/projectConfig.ts`** — read/write/normalize `hyperframes.json`. Tolerant to missing and partial configs
- **`packages/cli/src/utils/clipboard.ts`** — minimal cross-platform clipboard (pbcopy / clip.exe / wl-copy / xclip / xsel). Zero deps. Gracefully no-ops in headless environments
- **`packages/cli/src/commands/init.ts`** — write `hyperframes.json` during scaffold if not already present
- **`packages/cli/src/cli.ts`** + **`help.ts`** — register `add` under Getting Started (directly below `init`)

Design doc: [Hyperframes Catalog System](https://www.notion.so/heygen/Hyperframes-Catalog-System-Design-Plan-341449792c69813f899dcd53b4c0383a).

## UX

```bash
# Scaffold a project (now writes hyperframes.json too)
npx hyperframes init my-video --example blank
cd my-video

# Add a block — files land, snippet copied to clipboard
npx hyperframes add claude-code-window
#  ✓ Added claude-code-window (hyperframes:block)
#    compositions/claude-code-window.html
#
#  Include snippet:
#    <iframe src="compositions/claude-code-window.html" data-start="0" data-duration="6"></iframe>
#
#  Copied to clipboard — paste into your host composition.

# Add a component effect
npx hyperframes add shader-wipe

# Headless / CI — no clipboard, JSON output for tooling
npx hyperframes add shader-wipe --no-clipboard --json
```

Running `hyperframes add warm-grain` (an example) errors clearly pointing to `init --example`.

## Docs (bundled in this PR per the tracker principle)

- `docs/packages/cli.mdx` — new `add` subsection under Commands (flags, examples, trigger rules) + new `hyperframes.json` section describing the config file shape

## Tests

- **`packages/cli/src/commands/add.test.ts`** — 11 tests:
  - `remapTarget` / `buildSnippet` pure helpers (5 tests)
  - `runAdd` integration against a mocked `fetch` registry: block install lands files + returns snippet, component install respects `paths.components` remap, example-typed names throw `AddError` with code `example-type`, unknown names throw `AddError` with code `unknown-item` (4 tests plus 2 covering block default path and non-default path preservation)
- **`packages/cli/src/utils/projectConfig.test.ts`** — 9 tests:
  - Write/read round-trip, partial-config normalization, corrupt-file handling, absent-file fallback to defaults, custom paths preserved
- **CLI suite:** 92 passed (was 72 on #255, **+20**). Same 4 pre-existing failures unchanged

## Scope decisions

- **`init.ts` full port to new resolver deferred.** The original plan bundled a removal of the `packages/cli/src/templates/` compat shim. That's ~300 more lines and isn't required for `add` to work. The compat shim from #254 still functions; a separate cleanup PR handles it
- **No ajv runtime schema validation.** Manifests are trusted as schema-valid. Full validation lands when third-party registries arrive (PR 14/15). Path safety is still enforced by the installer's `assertSafeTarget` guard
- **Default project paths stay under `compositions/`.** Blocks → `compositions/<name>.html`; components → `compositions/components/<name>/<file>`. Users override via `hyperframes.json#paths`

## Breaking / migration

**None.** Pure additive — new command, new file types, no existing commands or flags change. `init.ts` now writes `hyperframes.json` but that's a new additional file, not a modification of existing output.

## Stacks on

#255 — base branch. When #255 merges, this rebases onto `main`.

## Next in stack

PR 6 — `feat(registry): seed block — claude-code-window`. First real registry item. Exercises the full `hyperframes add <name>` flow end-to-end against a committed item on `main`.

Vance IngallsandClaude Opus 4.6 fc973ee2e8 feat(lint): add rules for missing data-start, template wrapper, and DOCTYPE 
Three new lint rules that catch structural issues causing compositions
to fail silently in preview:

- root_composition_missing_data_start: Root composition needs data-start="0"
  for the runtime to begin playback
- standalone_composition_wrapped_in_template: index.html should not be
  wrapped in <template> (only sub-compositions use that)
- root_composition_missing_html_wrapper: index.html needs <!DOCTYPE html>
  and <html> wrapper for the bundler

Also adds rawSource to LintContext so rules can inspect pre-template-stripped
HTML, and isSubComposition to linter options so rules can distinguish root
from sub-composition files.

Miguel Ángel 43e9252065 feat: add MOV (ProRes 4444) as transparent video output format (#224) 
## Summary

- Adds `--format mov` to the render CLI for ProRes 4444 transparent video output
- ProRes 4444 with alpha is the industry standard for transparent video overlays, supported by CapCut, Final Cut, Premiere, DaVinci, and After Effects
- WebM VP9 alpha technically works but is ignored by all major video editors — only browsers decode it
- Adds MOV to the studio export dropdown alongside MP4 and WebM

## Transparency format comparison

| Format | Codec | Alpha | Video editors | Browsers | File size |
| --- | --- | --- | --- | --- | --- |
| **MOV** | ProRes 4444 | Yes | CapCut, Final Cut, Premiere, DaVinci, After Effects | No (won't play in browser) | Large (~5-40 MB) |
| **WebM** | VP9 | Yes | None (shows black) | Chrome, Firefox | Small (~200 KB) |
| **MP4** | H.264 | No | All | All | Small |

> **Note:** ProRes MOV files do not play in Chromium browsers — they are an intermediate/editing format, not a delivery format. Use [rotato.app/tools/transparent-video](https://rotato.app/tools/transparent-video) to verify transparency works correctly.

## Changes

- **CLI**: Add `mov` to `--format` validation, examples, and output path logic
- **Engine**: `getEncoderPreset()` returns ProRes 4444 (`yuva444p10le`) for `mov` format; handle `.mov` in `applyFaststart` and `muxVideoWithAudio`; add `pix_fmt` to streaming encoder ProRes path
- **Producer**: Treat `mov` like `webm` for alpha capture (PNG frames, screenshot mode, `forceScreenshot`)
- **Studio**: Add MOV option to export format dropdown and render queue hook
- **Core**: Add `mov` to studio API types, render route, and mime helpers
- **Tests**: Add encoder preset tests for mov format (42 total, all passing)

## Usage

```bash
hyperframes render --format mov --output overlay.mov
```

## Test plan

- [x] `pnpm build` passes
- [x] `pnpm --filter @hyperframes/engine test` — 42 tests pass (2 new for MOV)
- [x] `oxlint` and `oxfmt` clean on all 12 changed files
- [x] End-to-end local render produces ProRes 4444 (`yuva444p12le`) with working alpha
- [x] Docker render with `--format mov` — ProRes 4444 confirmed via ffprobe
- [x] Studio dropdown shows MOV option in built JS
- [x] Transparency verified with [rotato.app/tools/transparent-video](https://rotato.app/tools/transparent-video)
