* refactor: extract @hyperframes/lint package from core
Moves all lint rules, hyperframeLinter, lintProject, and related types
from packages/core/src/lint/ into a new standalone packages/lint package.
Core keeps a thin re-export stub at @hyperframes/core/lint for backward
compatibility. Consumer imports (cli lint command, producer hyperframeLint)
are updated to import from @hyperframes/lint directly.
Depends on @hyperframes/parsers (PR #1755).
* fix: restore postcss-selector-parser in core (sourceMutation.ts still uses it)
* fix(ci): add parsers+lint to Dockerfile and build before preview tests
* chore: update bun.lock after restoring postcss-selector-parser dep
* test(cli): update lintProject test for string-dir signature from @hyperframes/lint
* refactor(core): single-source the lint engine in @hyperframes/lint
Delete core's byte-identical copy of the lint rule engine and re-point
staticGuard at @hyperframes/lint, so the render-time render-gate and the
studio preview share one rule engine instead of two copies that could
silently diverge. Back-compat preserved via the @hyperframes/core/lint stub.
Addresses review feedback on the dual-copy footgun.
* fix: handle caption skin workflow
* docs(skills): simplify the finalize step across video workflows
- Drop --strict-layout; all skills use plain `hyperframes inspect`
- Add the caption text_box_overflow false-positive note to faceless-explainer
- On a failed check, the orchestrator makes the cheapest safe edit itself
(no worker re-dispatch / Step 3 backtrack language)
- Snapshot: glance at the stitched contact-sheet.jpg and move on

* feat(auth): onboarding-first `auth status` + shared TTS/BGM preflight
When no HeyGen credential is configured, `hyperframes auth status` now
prints registration-first guidance instead of a terse error:
- Interactive / agent-driven sessions get sign-in guidance led by
`hyperframes auth login` (the OAuth step that also creates an account
and is shared with heygen-cli), and never steer users to a per-repo
`.env`. CI / non-interactive runs get a terse note. Exit 1 is kept so
the "am I logged in?" `$?` contract still holds.
- It probes which local engine voice/music will fall back to (Kokoro /
MusicGen, mirroring the skill resolution order) and whether their
Python deps are installed, with a pip hint when missing. `--json`
exposes `recommended_action` + `offline_engines` for skills to branch.
- `doctor` gains matching "TTS (Kokoro)" / "BGM (MusicGen)" checks via
the same shared probe (findPython/hasPythonModules extracted to
tts/python.ts; provider resolution in audio/providers.ts).
Every TTS/BGM workflow now relays this at Step 0 (setup) instead of
improvising its own "missing key" prompt: pr-to-video, product-launch-
video, faceless-explainer, website-to-video, music-to-video. The
canonical behavior + key-priority table live once in hyperframes-media.

* feat(pr-to-video): scale recommended video length to PR change size
Step 0 led with a fixed ~60-90s length default. Now the recommended
length is derived from the PR's diff stat (lines added+deleted, nudged
by file count) on a tier scale (trivial ~20-40s → large ~110-180s, hard
cap ~3 min), reusing the same PR peek already done to infer the angle.
The agent states the basis when proposing it, and a huge PR with one
headline change still stays tight. User can always override.

* fix(captions): embed brand fonts whose files use separators
brandFontFaces() matched font files by stripping only whitespace, so an
underscore/hyphen-named file (TT_Norms_Pro_Bold.woff2) never matched the
family key "ttnormspro" — captions shipped with no @font-face, the
font_family_without_font_face bug. Now both family and filename normalize
away all non-alphanumerics; families match longest-key-first so a parent
family can't swallow a more specific one's files (TT Norms Pro vs Mono);
each file is claimed once; "demibold" ranks before "bold"; and when
nothing matches it warns loudly at build time instead of returning "".
Also: parseFonts() falls back to h1/h2/title/hero display roles, and the
frame-worker + caption authoring docs spell out that only shipped font
files render — no system CJK/Devanagari families on the headless renderer.

* fix(hyperframes-media): enforce sign-in preflight on standalone BGM/TTS
A one-off "generate me a BGM" request went straight to local MusicGen
without recommending sign-in: bgm.md/tts.md framed the no-credential path
as an automatic fallback, so the generation path bypassed the Preflight
stop, and the preflight used a bare `hyperframes auth status` that isn't
on PATH in a fresh `npx skills` project.
- Preflight now applies to one-off generation as well as workflows, uses
`npx hyperframes auth status`, and says: if the CLI can't run, still
recommend signing in and STOP — never treat "no credential" as a silent
green light for local generation.
- bgm.md and tts.md point at the Preflight before generating, reframing
local generation as the fallback the user opts into, not a default.

* docs(auth): add Authentication & API keys guide
Document signing in, the keys each capability (voice, music, capture)
uses, their resolution priority, and the fully local fallback. Add the
guide to the nav and cross-link it from the cloud deploy note and the
CLI env-var reference.

* fix(lint): strip HTML comments in a fixpoint loop (CodeQL)
Single-pass <!-- --> removal can re-form a complete comment from
adjacent markers (e.g. `<<!-- -->!-- ... -->`), letting a decoy
<template> survive and hijack the template-boundary match. Loop to a
fixpoint, mirroring the captions.mjs precedent; add a regression test
that fails on single-pass (2 root findings) and passes on the loop.
Also wrap the build-frame.mjs node:fs imports to satisfy oxfmt — the
new copyFileSync import pushed the line past the width limit, which
was the sole cause of the Format / Preflight CI failures.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(lint): strip HTML comments with a linear scan (CodeQL ReDoS)
The fixpoint loop still ran a /<!--[\s\S]*?-->/ regex per pass, which
backtracks O(n^2) on inputs with many unterminated "<!--" — CodeQL
js/polynomial-redos (high). Looping the same regex (the prescribed
fix) never addressed this; only the regex itself does.
Replace it with an indexOf-based linear strip in utils.ts
(stripHtmlComments), kept in a fixpoint loop so markers that re-form
when a comment is removed are still stripped. 200k unterminated
"<!--" now strips in ~3ms instead of quadratic time; behavior is
otherwise unchanged — unterminated comments are kept verbatim, as the
old regex left them. The re-forming regression test still guards it.

* fix(auth): make TTS/BGM sign-in guidance accurate and runnable
From team review of the not-signed-in onboarding:
- OAuth is a `hyperframes auth login` feature only. The separate `heygen`
CLI is API-key-only — `heygen auth login` stores a pasted key, it is not
OAuth and does not create an account. Stop presenting the two CLIs as the
same OAuth/sign-up step.
- Use `npx hyperframes` in every imperative and runtime hint. Bare
`hyperframes` is not on PATH on a fresh machine (command not found); only
`npx hyperframes` is guaranteed. Also updates the JSON recommended_action.
- Drop `heygen auth login` from the terminal/skill onboarding: it needs its
own install and there is no `npx heygen`, so it was a command-not-found
trap. The shared-credential fact stays in the reference docs.
Covers the `auth status` guidance + tests, the Authentication docs, the
shared hyperframes-media preflight (SKILL, requirements, tts, error hints),
and the `npx hyperframes auth status` preflight in every TTS/BGM workflow
(pr-to-video, product-launch-video, faceless-explainer, website-to-video,
music-to-video).

gsap_css_transform_conflict existed but missed the most common real-world
shape (a label centered with CSS translateX(-50%) plus a GSAP xPercent that
stacks to -100% in the capture path), for three independent reasons:
- selector matching was exact-string, so a scoped/grouped GSAP selector
("#root .label, #root .sub") never matched a CSS class rule (.label)
- the acorn parser only captures timeline-rooted calls (tl.to/tl.set), so a
standalone gsap.set("#root .label", { xPercent: -50 }) was invisible to it
- lintProject read compositions/ non-recursively, so per-frame compositions
in compositions/frames/*.html were never linted at all
Fix: token-decompose grouped/descendant/compound selectors and match by
id/class against CSS transform rules; additionally scan standalone gsap.*
transform calls; and recurse into compositions/ subdirectories so frame
sub-compositions are linted.
Adds unit tests (grouped gsap.set repro, descendant tl.to, negative case) and
an end-to-end lintProject test that writes compositions/frames/04-*.html and
asserts the conflict is reported there.

For the hyperframes.dev website-to-video flow. Real-AI-test runs against
heygen.com, huly.io, and heygen-showcase surfaced two gaps: (1) capture's
logo / asset-captioning signals missed modern React/Tailwind builds; and
(2) there was no CLI surface to pull the videos the manifest references.
New command:
• `hyperframes capture-video <project>` — on-demand downloader for
entries in capture/extracted/video-manifest.json. Capture writes the
manifest + preview PNGs but skips the mp4s; this pulls one entry by
`--index N` (matched against the entry's `index` field, NOT array
offset — gaps are possible when a preview screenshot fails). SSRF-safe
via safeFetch, 250 MB cap, content-type whitelist, race-free
exclusive-create write. Layout-aware (handles both standalone capture
and W2H project layouts).
Capture pipeline fixes:
• Structural logo signals (assetCataloger + tokenExtractor): inBanner /
inHomeLink / matchesTitleBrand. Class-substring alone caught 0/32 SVGs
on heygen.com — modern builds don't put 'logo' / 'brand' in any
className.
• Content-hash SVG slugs (assetDownloader): `svg-<8char-sha1>.svg` —
label-derived slugs mis-attributed partner-logo carousels
(heygen-logo.svg actually contained Google, hubspot-logo.svg contained
Trivago, etc.). Content-hash names are invariant by construction.
• SVG → PNG rasterization before Gemini Vision (contentExtractor): the
raw-SVG-as-text path was hallucinating wordmarks (VIVIENNE for HubSpot,
'wrestling' for Workday). Adds polarity detection so a white-glyph SVG
flattened to a blank PNG gets inverted before captioning. LOGO tag in
asset-descriptions.md when structural signals fire (independent of
Gemini key presence).
• Double-escape \/ inside the page.evaluate template literal in
assetCataloger + tokenExtractor: the original `/^https?:\/\/.../`
collapsed to `/` mid-template and threw `Unexpected token ^`. Capture
was 100% blocked on this until the escape was fixed.
• `asset-descriptions.md` header branches on Gemini-key presence with
an explicit 'Vision OFF — catalog-derived descriptions' warning.
New lint rule:
• `lintMissingLocalAsset` (cli/utils/lintProject): scans <video> / <img>
/ <source> src for local files that don't exist in the project.
Empirically the most common sub-agent mistake across multi-URL runs
(~5+ per run). Uses `resolveExistingLocalAsset` so the existence check
matches the bundler's notion of 'resolves'. Masks comment / style /
script ranges before scanning so a literal `<img src=missing.png>`
inside a tutorial comment isn't reported.
Tests: 17 new for capture-video (safeFilename decoding/sanitization,
VIDEO_CONTENT_TYPE_RE accept/reject, pickManifestEntry index-field lookup
with gaps, URL-mismatch + bad-index rejection, --index over --url
priority); 70 cases under lintProject.test.ts covering the new rule and
existing rules.
Sibling PRs in this stack:
• #PR_A1 — fix(producer): __dirname ESM banner shim
• #PR_A2 — fix(core/lint): findRootTag masks comment/style/script
* 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.
* fix(lint): await async lintHyperframeHtml in all callers
lintHyperframeHtml became async (gsap rules use dynamic import)
but lintProject and check-hyperframe-static weren't awaiting it,
causing typecheck failures and runtime crashes in CI.
Also wire LintRule type in gsap rules to fix fallow unused-type
finding, and suppress render.ts exported-for-tests symbols.
`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.
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.

## What
Added GSAP CDN imports to all template compositions and improved project linting to skip template placeholders.
## Why
Templates were missing GSAP script imports, causing JavaScript errors when GSAP animations tried to execute. The linter was also incorrectly flagging template placeholder values like `__VIDEO_SRC__` as missing audio sources.
## How
- Added `<script src="https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js"></script>` to all composition HTML files
- Updated `lintAudioSrcNotFound` function to skip template placeholders matching the pattern `__[A-Z_]+__`
- Fixed GSAP animation properties by adding `overwrite: "auto"` to prevent conflicts
- Replaced CSS transforms with GSAP `gsap.set()` calls for better animation control
- Moved video elements outside timed containers in some templates to avoid nesting issues
- Standardized transcript data format to use double quotes for JSON consistency
- Added proper timeline initialization with `window.__timelines = window.__timelines || {}`
- Enhanced caption styling with overflow handling and max-width constraints
## Test plan
- [x] Manual testing performed
- [x] Verified GSAP animations work correctly in all templates
- [x] Confirmed linter no longer flags template placeholders as errors
- [x] Tested video playback and audio synchronization
## Summary
- Respect `--json` flag on all lint exit paths so agents always get machine-readable output
- Separate `infoCount` from `warningCount` in linter results (was conflated)
- Display `info` vs `warning` severity distinctly in lint output
## Summary
- **Lint rules** catch media elements missing `id` (renderer silently skips them), missing `src`, `preload="none"` (blocks renderer), and video nested in timed divs (freezes playback). Upgraded `video_nested_in_timed_element` from warning to error.
- **Compiler** strips `preload="none"` from media during compilation. Runs parallel, cached keyframe interval analysis via ffprobe — warns on sparse keyframes (>2s) that cause seek failures and audio/video desync. Suggested ffmpeg command preserves audio (`-c:a copy`).
- **Pre-render lint** lints `index.html` + all `compositions/*.html` sub-compositions before render via shared `lintProject()` helper. Warns by default; `--strict` blocks on errors, `--strict-all` blocks on errors + warnings.
- **Render orchestrator** logs a hint to retry with `--workers 1` when parallel capture times out on video-heavy compositions.
- **Refactor**: extracted `runFfprobe()` + `parseProbeJson()` helpers to deduplicate ~80 lines of spawn boilerplate across 3 ffprobe functions. Extracted `shouldBlockRender()` so strict flag tests exercise production code. Shared `lintProject()` used by both `lint` and `render` commands.
## Context
Discovered during a real composition build session where:
1. `<audio>` without `id` rendered silently (preview worked fine because runtime queries `[data-start]`, but renderer queries `[id][src]`)
2. `<video>` inside timed `<div>` froze on first frame
3. `preload="none"` caused 45s renderer timeout
4. YouTube clips with sparse keyframes from `yt-dlp --download-sections` caused audio/video desync
5. Parallel workers timed out on video-heavy compositions
## Test plan
- [x] Core: 365/365 tests passing (5 new lint tests)
- [x] Engine: 24/24 tests passing
- [x] CLI: 14/14 tests passing (7 lintProject + 7 shouldBlockRender)
- [x] Lint + format hooks pass
- [ ] Manual: create a composition with `<audio data-start="0" src="test.wav">` (no id) — verify `npx hyperframes lint` catches it
- [ ] Manual: run `npx hyperframes render --strict` with lint errors — verify it blocks
- [ ] Manual: run `npx hyperframes render --strict-all` with lint warnings — verify it blocks
