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.

* feat(studio,cli): music beat detection with timeline guides + headless beats CLI
Beat detection for music tracks: the Studio draws beat guides on the active
track, beats are user-editable and persist to a project file, and a new
`hyperframes beats` CLI generates that file headlessly before the Studio opens.
Detection lives in @hyperframes/core/beats (shared by Studio + CLI): an energy
onset detector cross-validated with bpm-detective, regularized to an octave-
aligned grid, silence-gated, with per-beat loudness. Music-only — an
<audio data-timeline-role="music"> is analyzed; voiceover is excluded.
Studio: green beat lines + draggable dots on the selected track; add at playhead,
drag to move, double-click to delete (audio scrubs); edits persist to
beats/<audio>.json and are undoable (interleaved with file history).
CLI: `hyperframes beats [dir]` runs the same detection in headless Chrome
(prebuilt browser bundle in dist) and writes the beat file.

* feat(studio): timeline beat-grid + zoom UX refinements
- Center-anchored magnify: zooming via the toolbar/slider keeps the time
at the viewport center fixed instead of anchoring at the left. Pinch
still anchors at the cursor.
- Move-snap to beats: dragging a clip snaps whichever edge (start or end)
is nearest a beat, matching the existing resize-edge snapping.
- Beat lines on track backgrounds: faint full-height beat lines now paint
behind the clips on every track lane (brightness scales with loudness);
the green dots stay on the active track's top bar.
- Waveform follows zoom: bars fill the full clip width and resample the
windowed peaks, so the waveform stretches with zoom instead of stopping
partway across a widened clip.
- Beat dots centered in the top bar: align the dot band to the clip top
(CLIP_Y) so the dots sit centered in the dark bar instead of being
bisected by the clip's top border.

* fix(studio): preserve media sourceDuration across element re-derivation
Moving a non-music clip re-derived the timeline elements into fresh
objects whose sourceDuration the DOM scan hadn't loaded yet. The async
probe skips srcs already in its cache, so the value was silently
dropped — trimFractions then returned no window and the trimmed music
waveform reset to the full source pinned at the track start.
Re-apply the cached probe duration synchronously on every derivation
(applyCachedSourceDurations) and extract the async probe loop into
probeMissingSourceDurations to keep useTimelinePlayer within the file
size limit.

* feat(studio): skip beat-snap on the music track, highlight move-snap target
The music track defines the beats, so moving or trimming it no longer
snaps to its own beats (isMusicTrack guard on both the move and resize
snap paths).
Moving another clip snapped only on drop with no cue. snapMoveStartToBeat
now also returns the beat it will snap to; BeatBackgroundLines draws that
beat's line as a bright neon-green glow while the clip's edge is within
the snap region, so the target is visible before drop.
Also drops .commitmsg.tmp, accidentally committed via git add -A.

* feat(studio): hide playhead while dragging a beat; default beat dots to music track
- Dragging a beat dot now hides the playhead guideline (new beatDragging
store flag set on beat pointer down/up) so its line doesn't track the
scrub and clutter the beat being moved.
- Beat dots render on the selected track, falling back to the music track
when nothing is selected.

* fix(core): remove polynomial-ReDoS regex from audioRelPathForSrc
CodeQL js/polynomial-redos: the lazy `.+?` followed by an optional
trailing `[?#].*$` backtracks polynomially on crafted `/preview/...`
inputs. Parse the preview-relative path with indexOf/slice instead, and
strip the query/hash with a single linear char-class search. Behavior is
unchanged for all preview/absolute/blob/data/bare inputs.

* fix(studio,core,cli): review hardening for beat detection + timeline UX
- playerStore.reset() now clears beat state (analysis, edits, undo/redo,
persist) so a project switch can't apply the previous project's beats,
undo stack, or file-writer to the new one.
- removeUserBeat returns the same reference on a no-op, and delete/move beat
actions skip committing when nothing changed — no more phantom undo
entries / debounced writes for no-op edits.
- regularizeBeats bails to raw onsets when the (octave-misread) tempo would
produce a sub-125ms grid, avoiding a tens-of-thousands-of-beats freeze.
- parseBeats clamps strength to [0,1] and rejects non-finite time/strength,
so a hand-edited file can't feed NaN into the gamma curve (Math.pow on a
negative base) and blank out beat markers.
- Start-edge beat-snap now also requires duration >= minDuration, matching
the end-edge guard, so a rightward snap can't collapse the clip.
- Center-anchor zoom effect always consumes its skip flag, so a pinch that
produced no pps change can't leave it stranded and skip the next zoom.
- Headless beats analyzer projects to {beatTimes,beatStrengths,bpm,confidence}
before returning, so page.evaluate no longer serializes the full decoded
PCM (channelData) across the CDP boundary.

parseBeats accepted any object with a beats array, so a future v2 beat file

* 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.

* 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}/** —

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".)

'</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.

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 <video> 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.

* 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.

HyperFrames MCP is rolling out to Grok this week. Add Grok alongside
Claude.ai and ChatGPT: new setup tab (catalog search + custom-URL
fallback), and include it in the title, intro, progress-notification
host list, issue-report host list, and widget-supported host list (Grok
renders MCP widgets).
Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
TTS/voiceover is disabled in the hosted MCP, so the public MCP guide no
longer reflects current functionality. Remove all voice/TTS mentions:
- "voice generation" from the compose agent's built-in skills list
- "voice selection" from the compose tool description
- "voice / TTS" from the "what the hosted MCP wraps" section
- "Selecting voice and style..." progress-notification examples
- brand-voice asset reference (agent can't synthesize speech anymore)
Also add guides/mcp to the Guides sidebar group — the page existed but
was only reachable by direct URL, not from the nav.

Plan documents are working artifacts that shouldn't be committed.
Removes three plans that were accidentally tracked and adds
docs/plans/ to .gitignore to prevent future occurrences.
Compositions are now self-contained: the compiler captures font files
and embeds them as woff2 data URIs, eliminating silent render-time
fallback when the render environment lacks the author's fonts.
Resolution order (each tier falls through to the next):
1. Existing @font-face → use as-is
2. Bundled alias (38 cross-platform mappings) → embed data URI
3. Google Fonts → fetch, cache, embed
4. Local system font → locate on OS, compress to woff2, embed
5. Local @font-face paths → read file, compress, inline as data URI
6. External CDN stylesheets → fetch CSS, extract @font-face, inline
7. Alias map fallback → closest bundled equivalent
8. Actionable error with guidance
Key changes:
- System font locator (macOS/Windows/Linux) with path-bounding and
symlink defense (realpathSync + O_NOFOLLOW)
- woff2 compression via wawoff2 (WASM, cross-platform)
- Multi-weight/style variant capture with length-sorted token matching
- External stylesheet inlining with SSRF defense (assertPublicHttpsUrl,
HTTPS-only, private-host blocking, 2MB cap, 4-concurrent limit)
- Studio auto-import via GET /fonts/file API + renderAliasFor() derived
from shared FONT_ALIAS_MAP (no more hand-curated drift)
- failClosedFontFetch throws on unresolved fonts in distributed renders
- Single source of truth: @hyperframes/core/fonts/aliases
- system_font_will_alias lint rule (escalates to warning for distributed)
- Default to Inter + JetBrains Mono in templates and CSS reset
* feat(gcp-cloud-run): add Google Cloud Run + Workflows distributed render adapter
Adds @hyperframes/gcp-cloud-run, the GCP counterpart to @hyperframes/aws-lambda
(issue #932). The OSS distributed primitives (plan, renderChunk x N, assemble)
are unchanged; this package is the storage/compute/orchestration glue.
Package: Cloud Run handler (one image, three actions), runs under bun; GCS
transport; in-image chrome-headless-shell resolver; client SDK
(renderToCloudRun, getRenderProgress, deploySite, computeRenderCost); Dockerfile;
Cloud Workflows definition; Terraform module; CLI cloudrun
deploy|sites|render|render-batch|progress|destroy with --output-resolution and
--strict-variables; 62 unit tests + docs + live smoke script.
Shared extraction (removes ~640 lines of adapter duplication): move the
cloud-agnostic config validator + content-hash into producer/distributed; both
adapters import them. Validated end-to-end on GCP at 37.4 dB PSNR vs baseline.

* fix(cli): resolve @hyperframes/gcp-cloud-run in the CLI build + root build
The CLI bundle (esbuild) couldn't resolve `@hyperframes/gcp-cloud-run/sdk`,
failing Build/Typecheck/CLI-smoke (and the perf/windows/regression jobs that
build first). Mirror the aws-lambda handling: mark the gcp adapter + its /sdk
subpath external in tsup.config.ts with a source alias, and add gcp-cloud-run
to the root `build` filter so its dist exists for publish + runtime.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(ci): copy gcp-cloud-run manifest in Dockerfile.test for frozen install
The regression test image runs `bun install --frozen-lockfile` after copying
each workspace package.json individually. The CLI now depends on
@hyperframes/gcp-cloud-run (workspace:*), so the frozen install fails to
resolve it unless its manifest is present. Add the COPY line.

* feat(cli): add machine-sizing flags to `cloudrun deploy`
Closes the parity gap with `lambda deploy` (which exposes --memory etc.).
`cloudrun deploy` now threads --cpu, --memory, --max-instances, and --timeout
into the Terraform apply; omitted flags keep the module defaults
(4 vCPU / 16Gi / 100 instances / 3600s). For finer control, apply the module
directly.

* fix(gcp-cloud-run): address PR review (security, waste, limits, alerts)
- server.ts: bucket-allowlist guard no longer fails open silently. Unset env
logs a one-time WARNING; "*" is an explicit opt-out; otherwise it enforces.
- server.ts: stop double-shipping audio.aac. It already rides in the plan
tarball every consumer downloads, so drop the redundant standalone upload
(plan) + re-download/overwrite (assemble); assemble reads it from the untar,
falling back to a supplied AudioGcsUri for compat.
- server.ts: chunk extension via path.extname() instead of slice(lastIndexOf).
- workflow.yaml: clamp parallel concurrency_limit to math.min(chunkCount, 20)
— Cloud Workflows hard-caps concurrent iterations at 20.
- Dockerfile: pin bun (bun-v1.3.9) so an interop change can't silently break
the image rebuild.
- terraform: add min_instances var (default 0); add a workflow-failure alert
(finished_execution_count status=FAILED) alongside the request-count one.
- costAccounting: document that displayCost excludes GCS storage/egress.
Verified against the actual APIs: @google-cloud/workflows@4.4.0
ICreateExecutionRequest has no executionId (so the idempotency-token suggestion
isn't available in this client); Workflows concurrency cap is 20; failure
metric is workflows.googleapis.com/finished_execution_count (status label).
174 adapter tests pass, fallow/oxlint/oxfmt/terraform clean.

* fix(gcp-cloud-run): address round-2 review — error code + CFR forwarding
- workflow.yaml: rename the zero-chunk failure code PLAN_TOO_LARGE →
PLAN_PRODUCED_ZERO_CHUNKS. The old code implied a size-ceiling breach (the
opposite cause), misleading anyone triaging the alert.
- workflow.yaml: forward Config.cfr to the assemble step
(`Cfr: ${("cfr" in config) and config.cfr}`). It was read by the handler
but never sent, so exact-CFR was silently off for every Cloud Run render.
Uses the same `in`-operator guard already proven in the retryable predicate.

* fix(release): include gcp-cloud-run in set-version PACKAGES list
set-version.ts (driven by release:prepare) bumps an explicit package list to
the shared version on each release. gcp-cloud-run was wired into the build +
publish.yml but missing here, so a release would leave it at a stale version
and publish.yml would push the wrong version. Add it so the new package
version-bumps + publishes in lockstep with the others.

* feat(gsap): add innerText support to GSAP inspector for counter animations (#1244)
Adds 'innerText' as a supported GSAP property so number roll-up animations
(count-up from 0 to some value) are visible and editable in the GSAP inspector
panel.
- Add 'innerText' to SUPPORTED_PROPS in gsapConstants.ts
- Add label 'Counter Value', tooltip, and step constraint (1) in
gsapAnimationConstants.ts
The snap modifier that controls integer rounding is already preserved
verbatim via the EXTRAS_KEYS round-trip, so rounding behavior survives
edits without any additional UI changes.
Closes#1179
* feat(registry): add text-effects catalog section and morph-text component
Introduces a new "Text Effects" catalog section (below Effects) for text-focused visual components.
- Add `text-effects` BlockCategory to core registry types with violet color
- Add `text-effect` tag resolver in resolveBlockCategory (checked before generic `effect` tag)
- Tag caption-blend-difference, texture-mask-text, and morph-text with `text-effect`
- Update studio catalog order and color map to include text-effects
- Add morph-text component: gooey SVG threshold morph cycling through editable statements
using GSAP seekable proxy pattern for deterministic/seekable rendering

* chore(registry): add demo.html for morph-text catalog preview rendering
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(registry): address PR review feedback on morph-text and text-effects
- Restore `effect` tag on caption-blend-difference and texture-mask-text
alongside `text-effect` so existing tag-equality searches/analytics still match
- Fix morphPause script fallback from "0.25" to "1.5" to match data attribute default
- Add Math.max(0, ...) guard to blur values (intent clarity)
- Add prefers-reduced-motion: skip morph and show first word statically
- Remove CATEGORY_ORDER record from useBlockCatalog; derive order from
BLOCK_CATEGORIES array (single source of truth, no drift)
- Add comment to demo.html documenting its purpose (catalog preview script only)

## What
Adds an auto-detected **low-memory safe render profile**. On hosts at or below 8 GB total RAM, the render pipeline collapses to its cheapest shape instead of running multiple concurrent Chrome instances.
When `lowMemoryMode` is active and the user hasn't passed `--workers`, the orchestrator:
- **skips auto-worker calibration** — no throwaway second Chrome just to time 5 frames;
- **pins to a single worker** — so the probe Chrome is reused for capture, never N concurrent;
- **prefers screenshot capture over BeginFrame** — avoids the BeginFrame protocol-timeout → relaunch churn on slow hardware;
- logs a one-line explanation of what it did and how to override.
Builds on #1221 (merged), which fixed the calibration timeout cap, the `<= 8192` boundary, and added the CLI timeout flags.
## Why
Reported in #1218 / #1219: renders on 8 GB laptops sit at low progress for minutes or stall. Root cause (per the triage thread) is architectural — the default pipeline launches up to 4 Chrome instances sequentially/overlapping (probe, calibration, capture, screenshot-fallback), each ~256 MB+, on machines with ~3 GB free. The concurrent browsers drive memory pressure that makes every CDP call slow and spikes V8 GC pauses.
#1221 made the timeouts and memory flags *apply correctly*; this PR removes the expensive shape entirely on the machines that can't afford it, rather than tuning it. "Smarter by default."
## How
- **`packages/engine/src/services/systemMemory.ts`** (new): one shared `isLowMemorySystem()` / `getSystemTotalMb()`, de-duplicating the `totalmem()` reads previously copied in `config.ts` and `browserManager.ts`. Threshold is inclusive (`<= 8192 MB`) — real "8 GB" hardware reports ~7600–8192 MB after firmware/iGPU reservations, so a strict `<` would skip the optimisation on the very hardware that needs it.
- **`config.ts`**: new `lowMemoryMode` field on `EngineConfig`, resolved tri-state — explicit override → `PRODUCER_LOW_MEMORY_MODE` (on/off) → auto-detect from total RAM.
- **`renderOrchestrator.ts`**: gate calibration off, pin workers to 1, force screenshot capture, and emit a safe-mode log line when `lowMemoryMode` is set and `--workers` is absent.
- **`render.ts`**: `--low-memory-mode` / `--no-low-memory-mode` override (sets the env var the producer's `resolveConfig` reads) + docs table entry.
Fully overridable: an explicit `--workers N` restores calibration-free parallelism; `--no-low-memory-mode` / `PRODUCER_LOW_MEMORY_MODE=false` restores the full default shape.
### Deliberately deferred (separate PRs)
- **Reuse the probe session for calibration**: only executes on the tier *above* 8 GB (safe-mode skips calibration on the target boxes). A correct BeginFrame-mode reuse would lose calibration's fast-fail-to-screenshot timeout — real risk on a path the reported scenario never hits. Better scoped on its own.
- **Retuning `calculateOptimalWorkers`'s `totalmem*0.5/256` memory model**: hot path for *all* renders incl. servers/Lambda, outside this PR's local-laptop scope.
## Test plan
- [x] Unit tests added/updated — `systemMemory.test.ts` (8192 boundary cases), `config.test.ts` (tri-state env resolution + explicit-override precedence). Engine suite passes (25 relevant tests).
- [x] `tsc` clean across engine/producer/cli; `oxlint` + `oxfmt` clean; removed an unused export so the `fallow --fail-on-issues` dead-code gate stays green.
- [x] Documentation updated — `docs/packages/cli.mdx` render-flags table.
- [ ] Manual testing on a real ≤ 8 GB host — not yet run; behaviour is unit-covered and the safe path (1 worker + screenshot) is already a supported render shape.
Note: one pre-existing producer test (`rejects a maliciously crafted key…`) fails identically on `main` — environment-specific path test, unrelated to this change.
React components and DOM utilities for the snap system:
- SnapGuideOverlay: pre-allocated div pool (6 guides + 4 spacing)
for ref-driven guide line rendering during drag
- SnapToolbar: magnet/grid toggle with S/G keyboard shortcuts,
right-click grid popover for spacing config
- GridOverlay: CSS repeating-linear-gradient grid, GPU composited
- snapTargetCollection: walks iframe DOM tree to collect visible
elements as snap targets, cross-iframe safe (nodeType check)
* docs: add Reap as HyperFrames adopter
Reap (reap.video) is integrating HyperFrames as a renderer for lightweight
video edits and renders in its AI-driven video processing pipeline for
social content creation.
* docs: refine reap adopter entry and add to docs site
- ADOPTERS.md: rename "Reap" -> "reap" to match brand casing, and
update the use-case sentence to describe HyperFrames' role inside
reap (matches the HeyGen/tldraw convention on this page).
- docs/community/adopters.mdx: add reap card to the Production
CardGroup so the hosted adopters page at
hyperframes.heygen.com/community/adopters mirrors ADOPTERS.md.
Addresses review feedback from @miguel-heygen on #876.
* 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.

## What
- Add `bun run release:prepare <version>` as the maintainer-facing stable release entrypoint.
- Make the first run draft missing changelog artifacts and intentionally exit before tagging; rerunning after manual review delegates to `set-version`.
- Tighten the direct `set-version` guard so stable releases also fail when generated TODO changelog copy is still present.
- Update maintainer docs to recommend `release:prepare` while keeping `changelog:draft` as the lower-level regeneration tool.
## Why
Stable releases should be hard to run without reviewed GitHub release notes and Mintlify changelog copy. This keeps the existing manual rewrite step, but makes the expected path one command that engineers can rerun after review.
## How
- Added `scripts/release-prepare.ts` with parsing, draft/review/set-version action selection, and command forwarding.
- Added focused script tests for parser behavior, action selection, command forwarding, and TODO detection.
- Extracted shared script CLI parsing helpers so `changelog:draft` and `release:prepare` use the same option handling.
- Adjusted `changelog:draft --write` so an existing release file is left unchanged unless `--force` is passed, while still allowing a missing docs entry to be added.
## Test plan
- [x] Unit tests added/updated: `bun run test:scripts`
- [x] Format check: `bun run format:check`
- [x] Lint: `bun run lint`
- [x] Typecheck: `bun run --filter '*' typecheck`
- [x] Fallow audit: `bunx fallow audit --base origin/main --fail-on-issues`
- [x] Manual CLI checks: `bun run release:prepare --help`; `bun run set-version 9.9.9` fails before mutation when changelog artifacts are missing
- [x] Documentation updated
* feat(docs): add changelog release workflow
* fix(scripts): resolve CodeQL findings in release scripts
- draft-changelog.ts: replace existsSync+writeFileSync check-then-act with
an atomic exclusive-write flag (flag: wx) to fix the js/file-system-race
TOCTOU finding; overwrite only under --force (flag: w).
- set-version.ts: switch execSync shell-string git calls to execFileSync with
argument arrays so the interpolated version/paths can never be interpreted
by a shell, resolving the js/indirect-command-line-injection findings.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(scripts): lower writeReleaseNotes complexity below CRAP threshold
The exclusive-write fix pushed writeReleaseNotes to cyclomatic 5 / CRAP 30.0
(fallow/high-crap-score, threshold 30.0). The '!force' guard in the catch is
redundant — EEXIST is only reachable under the 'wx' flag (force=false), since
'w' overwrites without throwing. Dropping it returns the function to cyclomatic
4 / CRAP 20 with identical behavior.

* fix(registry): remove placeholder preview URLs for unrendered Apple Terminal themes
The 8 themes without rendered videos (clear-dark, homebrew, novel,
ocean, pro, red-sands, silver-aerogel, solid-colors) had preview.video
URLs pointing to non-existent S3 objects, returning 403. Removed the
preview field from their registry-item.json and the video embed from
their MDX pages until renders are available.
The 4 themes with uploaded videos (basic, clear-light, grass, man-page)
retain their preview URLs and are live on CDN.
* fix(registry): add apple-terminal tag so npx hyperframes add apple-terminal works
* feat(registry): render + upload all 12 Apple Terminal preview videos to CDN
Rendered the 8 missing themes (clear-dark, homebrew, novel, ocean, pro,
red-sands, silver-aerogel, solid-colors) using npx hyperframes@latest
render and uploaded to the hyperframes CDN. All 12 themes now have
live preview.video URLs and video embeds in their MDX pages.
All 12 CDN URLs return 200.
* style: format Apple Terminal HTML and JSON files with oxfmt
