* feat(core): add pure resolveEditingAffordances (edit capabilities + section applicability)
* fix(core): replace prohibited as-cast and !-assertions in isIdentityTransform
* refactor(studio): consume core resolveEditingAffordances; drop duplicated capability + section logic
- affordances.ts: add matrix3d identity-transform branch (was missing, caused test regression)
- domEditingLayers: add domEditSelectionToFacts mapper; resolveDomEditCapabilities is now a thin
wrapper over core (kept for backward-compat — tests + barrel import it); isTextEditableSelection
delegates to core sections.text; drop parsePx + isIdentityTransform imports (now in core)
- PropertyPanel: import resolveEditingAffordances + domEditSelectionToFacts; compute sections once;
replace isMediaElement/isColorGradingCapableElement/timing inline check with sections.*
- propertyPanelMediaSection: delete isMediaElement (no remaining callers)
- propertyPanelColorGradingSection: delete isColorGradingCapableElement (no remaining callers)

* feat(sdk): add browser-only resolveElementAffordances adapter over core
* fix(sdk): add position to inlineStyles, replace ! assertion with guard in test
- Add missing 'position' key to inlineStyles in affordances.ts to match computedStyles
- Replace non-null assertion (doc.defaultView!) with proper null guard in test
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
* fix(editing): resolve code-review findings on affordances feature
Max-effort review (8 verified findings) fixes:
Correctness regressions (studio behavior):
- SVG selection crash: dropped `classNames` from EditableElementFacts
entirely (it was never read by the resolver), which removes the
`.className.split()` calls that throw on SVGElement (className is an
SVGAnimatedString, not a string). Masked in tests by happy-dom.
- Timing panel hidden for GSAP-only layers: domEditSelectionToFacts now
takes animationCount from the caller; PropertyPanel feeds the live
gsapAnimations prop (selection.gsapAnimations is never populated).
Cleanups:
- Removed dead inline `position` key from SDK adapter (core reads position
only from computedStyles).
- Added sections-only `resolveEditingSections` export; PropertyPanel uses it
so panel re-renders no longer re-run the capability geometry parse.
- Declared happy-dom in packages/sdk devDependencies (was root-hoist only).
- Deduped the two capability fact-construction sites behind a shared
capabilityFacts() helper.
- parsePx now has a single source of truth in core; studio domEditingDom
re-exports it so the copies can't drift. isIdentityTransform is now
core-internal (studio's only consumer moved to core in the prior task).
bun.lock also reconciles stale 0.7.17->0.7.21 package versions.

* fix(skills): storyboard review — bg-on-clip rule, slideshow output, parser parity guard
Addresses the storyboard-angle review (jrusso1020):
- M1 (invisible text): frame-worker.md (x3) + SKILL.md Step 5 (x3) now require a
frame's full-bleed background on a class=clip layer, never the #root /
data-composition-id element (the root is clip-gated to its scene window, so a
background on it is not a dependable ground and dark text can land on the black
host body). The assembler already paints frame.md's canvas onto index #root as
the base ground; the per-frame clip rides on top.
- B3 (slideshow truncates to slide 1): slideshow/SKILL.md gains an Output section
(decks render via 'present'; 'render index.html' captures only the first
composition; linear main-line MP4 export is deferred).
- Parser drift: vendoredParity.test.ts guards the three vendored storyboard.mjs
copies (byte-identical + parse-parity with @hyperframes/core).
- skills-manifest.json regenerated for the edited SKILL.md files.

* fix(cli): storyboard review — lint, validate help, snapshot, inspect, capture, render
Addresses the CLI findings from the storyboard-angle review (jrusso1020):
- lint (@hyperframes/lint): accept vendor-prefixed system-font keywords
-apple-system / BlinkMacSystemFont so a system stack with a generic fallback no
longer trips font_family_without_font_face (+ test).
- help: list 'validate' under Project in 'hyperframes --help' (was runnable but
undocumented).
- snapshot: honor -o/--output (the flag did not exist; output was hardcoded to
snapshots/). The dir is resolved once and threaded through capture + contact
sheet + Gemini.
- snapshot: split font status into loaded / error / unused with a one-line
summary; only a real 'error' is reported as FAILED (an unrequested @font-face
is 'unused', not a contradiction with 'loaded').
- inspect: suppress text_occluded across a scene-to-scene crossfade (occluder in
a different data-composition-id mount while a scene is mid-fade); a same-scene
or two-settled-scenes overlap still flags.
- inspect: suppress content_overlap between in-flow siblings governed by the same
flex/grid container (tight stacks / number lockups are layout slop).
- capture: record source resolution (videoWidth/Height) in video-manifest.json
alongside the DOM display box; consumers size off the source dims.
- render: warn when the target carries a slideshow island (render captures only
the first scene, so the MP4 is truncated to slide 1; use 'present').

* fix(core): root-cause the id-less media wash in getAttr, drop the band-aid
The blank-wash/dropped-audio fix in #1790 added assignMissingMediaIds in the
producer to stamp ids onto id-less timed media. That was a band-aid: the real
cause is timingCompiler's getAttr, whose regex had no name boundary at all, so
getAttr(tag, "id") matched the trailing id="…" inside data-hf-id="…". compileTag
saw a phantom id and skipped its existing hf-video-N/hf-audio-N injection,
leaving the element with no real el.id — which the render pipeline keys off of.
Fix getAttr with the same (?<![\w-]) lookbehind used for the lint readAttr fix.
compileTag's auto-id injection now fires for data-hf-id-only media, in both the
main composition and sub-compositions (parseSubCompositions runs the same
compileTimingAttrs pass), so assignMissingMediaIds is removed entirely.
Extends the regression fixture with a standalone id-less <audio> (the dropped-
audio side, previously untested) and raises minAudioCorrelation to 0.9. Adds a
timingCompiler test for the data-hf-id/id boundary.
* test(producer): use seeded pink noise (not a pure sine) for fixture audio
A continuous sine anti-aligns under the audio cross-correlation (correlation
-1.0 from a sub-period offset). Broadband seeded noise correlates robustly.
* test: cover audio-side id injection via unit test; keep render fixture video-only
The audio render-baseline used synthetic sine/noise, which anti-aligns under
the harness audio cross-correlation (deterministic -1.0). Real audio fixtures
are unaffected. Cover the audio side of the boundary fix with a deterministic
timingCompiler unit test (id-less <audio> gets hf-audio-N) instead, and keep
the render fixture video-only.
* test(producer): regenerate baseline under the root fix (hf-video-N from compileTag)
Avoid the screenshot-path #1715 regression by skipping empty WAAPI/CSS animation scans per seek and classifying known software WebGL renderers correctly in browserGpuMode=auto.\n\nAddresses #1715.
* refactor: make @hyperframes/lint depend only on parsers, not core
Relocates the leaf utilities lint pulled from core — URL/asset-path helpers,
font aliases, and the slideshow manifest parser — into the standalone
@hyperframes/parsers base, and drops @hyperframes/core from lint's
dependencies. Core keeps back-compat re-export stubs at the old paths, so
producer/studio/cli are unchanged.
Why: lint was the lightweight validator from #1749, but depending on core
transitively pulled studio-server (hono) and bpm-detective — irrelevant to
linting. Now installing @hyperframes/lint pulls only parsers + postcss, and
the core<->lint dependency cycle is gone.
- parsers main entry stays browser-safe (pure utils only); the node:path
asset helpers live behind the new @hyperframes/parsers/asset-paths subpath
- slideshow parser exposed via @hyperframes/parsers/slideshow
* feat(lint): add browser entry; harden CSS url() regex (ReDoS)
@hyperframes/lint/browser — a fully client-side rule engine (lintHyperframeHtml,
lintMediaUrls, shouldBlockRender) with zero node: builtins, so browser-only
editors can validate compositions with no Node.js and no server round-trip.
Closes the browser-validation ask on #1749.
- shouldBlockRender extracted from the fs-bound project.ts into its own pure
module so the browser entry stays node-free
- pure composition primitives (data types, font aliases, URL helper) exposed via
a new recast-free @hyperframes/parsers/composition subpath, so the browser
bundle tree-shakes out the GSAP/recast machinery (verified: esbuild
platform=browser bundles with 0 node builtins)
- lint built with a platform:browser tsup pass — compile-time guarantee the
browser entry never pulls a node builtin
- harden CSS_URL_RE against polynomial ReDoS (CodeQL js/polynomial-redos);
behavior-preserving, verified against existing tests + an old/new parity check
- parsers/lint marked sideEffects:false
- pickBestAnimation is group-aware: a rotation/3D edit no longer merges into a
position tween — a fresh same-group tween with a 0% baseline is created instead
- editing at a playhead past the tween extends it and keyframes there (matches drag)
- update-keyframe MERGES into the existing keyframe instead of overwriting, so
editing one property no longer drops z/transformPerspective (the lens then
animated from 0 and the element popped)
- dragging a keyframed element with a constant position tween keyframes rather
than writing a static set
* refactor: extract @hyperframes/studio-server package from core
Moves all studio-api routes, helpers, and Hono server wiring from
packages/core/src/studio-api/ into a new standalone packages/studio-server
package (@hyperframes/studio-server).
Core keeps thin re-export stubs at @hyperframes/core/studio-api and the
subpath helpers (screenshot-clip, draft-markers, etc.) for backward
compatibility. Consumer imports (cli studioServer, vite adapter/config,
producer htmlCompiler, studio manualEditsTypes) are updated to import from
@hyperframes/studio-server directly.
Also exports rewriteInlineStyleAssetUrls from @hyperframes/core root (was
in compiler/rewriteSubCompPaths.ts but not re-exported), required by
@hyperframes/studio-server/helpers/subComposition.
Removes postcss-selector-parser from @hyperframes/core dependencies (moved
to @hyperframes/studio-server which owns the routes that used it).
Depends on @hyperframes/parsers (PR #1755).
* fix(ci): add parsers+studio-server to Dockerfile and build before preview tests
* fix(ci): build @hyperframes/studio-server before Test and studio load smoke
Studio's vite.config.ts imports @hyperframes/studio-server, which resolves
via its "node" export condition to built dist. The Test and studio-load-smoke
jobs only built parsers + core, so esbuild's config load failed to resolve the
package entry. Build studio-server too.
* fix(studio): repoint sdkCutoverParity test import to studio-server
sourceMutation moved from core's studio-api to @hyperframes/studio-server;
the test still imported the deleted core path. This was masked while studio's
vite.config failed to load (couldn't resolve studio-server); now that the
config loads, the test runs and the stale import surfaced.
* 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.
## Summary
Extracts the GSAP parser/writer suite, HTML parser, hf-ids, spring-ease, and the shared composition data types out of `@hyperframes/core/src/parsers/` into a new, independently-publishable **`@hyperframes/parsers`** package.
This is the foundation of the [#1749](https://github.com/heygen-com/hyperframes/issues/1749) effort: make HyperFrames' parsing/linting/validation usable as plain libraries in a Node app, without shelling out to the CLI. Parsers is the standalone base every other extracted package builds on.
**Part 1 of 3** — splits #1754 into independently-reviewable pieces. Parts 2 (lint) and 3 (studio-server) stack on this branch.
## What moves
| | |
|---|---|
| Source moved out of core | **~9,900 LOC** (`src/parsers/` → `packages/parsers/src/`) |
| Total lines removed from core (incl. tests + goldens) | ~19,600 |
| Files relocated | 39 |
| Tests carried over | **660 passing** (5 skipped, 3 todo) |
The big movers: `gsapParser` / `gsapParserAcorn` (the recast + acorn dual parsers), `gsapWriterAcorn`, `gsapSerialize`, `gsapUnroll`, `htmlParser`, `hfIds`, `springEase`, `stableIds`, plus the `__goldens__` corpus.
## Bundle footprint of the new package
| Artifact | Size |
|---|---|
| `dist/` (unpacked) | 1.7 MB |
| npm tarball (packed) | 409 KB |
| `dist/index.js` | 90 KB (**~21 KB gzipped**) |
| Heaviest entries | `gsapWriterAcorn.js` 93 KB · `gsapParser.js` 91 KB |
Most of the weight is the GSAP AST machinery (recast/babel/acorn). It's tree-shakeable via subpath entries (`@hyperframes/parsers/hf-ids`, `/gsap-constants`, etc.) so a consumer that only needs `hf-ids` (2 KB) doesn't pull the parsers.
## How `@hyperframes/core` changes
The interesting part: **core sheds its entire AST toolchain.**
| core `dependencies` | before | after |
|---|---|---|
| count | 9 | 6 |
| removed | — | `@babel/parser`, `acorn`, `acorn-walk`, `magic-string`, `recast` |
| added | — | `@hyperframes/parsers`, `linkedom` |
Before this PR, importing `@hyperframes/core` at all dragged in babel + recast + acorn just to construct types. Now those live behind `@hyperframes/parsers`, and a consumer that only wants core's runtime/compiler types never resolves the parser stack. Core keeps thin `@deprecated` re-export stubs at the old subpaths (`@hyperframes/core/gsap-parser`, `/gsap-constants`, …) so nothing downstream breaks.
## Design notes
- **`"bun"` export condition before `"node"`** in every package export. Bun resolves the TypeScript source directly (no pre-built `dist/`), while Node/tsx/Docker contexts fall through to `"node"` → `dist/`. This keeps the dev loop zero-build while published artifacts stay Node-consumable.
- `@hyperframes/parsers` is **standalone** — zero `@hyperframes/*` dependencies — so it can be the base of the stack.
## Test plan
- [x] `bun run --filter @hyperframes/parsers test` — 660 tests pass
- [x] `bun run --filter @hyperframes/sdk test` — 382 tests pass
- [x] `bun run build` — full monorepo build succeeds
- [x] Fallow audit passes on CI
* feat(skills): product-launch-video + consolidate motion knowledge into hyperframes-animation
- Add the product-launch-video skill: shot-sequence architecture where each
visual frame is a time-coded shot sequence picked from a blueprint menu and
paced to the voiceover (anti-PowerPoint). Includes the frame-worker sub-agent,
story/visual/motion-design references, and audio/captions/transitions/
stage-assets/assemble-index scripts.
- Consolidate motion knowledge in hyperframes-animation as the single source of
truth: promote the updated atomic rules (31 -> 36) and rename product-launch-
video's archetypes into hyperframes-animation blueprints (13 -> 15, replacing
the old set). product-launch-video, faceless-explainer, and pr-to-video now
reference them via ../hyperframes-animation/{rules-index,blueprints-index}.md
and the rules/blueprints dirs. Fixes the discrete-text-sequence broken links;
blueprints no longer ship per-id runnable examples, so example references in
the consumers were dropped.
- Default HeyGen TTS voice to Marcia (deterministic; was the API's first English
voice, which drifts on catalog re-sort). Override with --voice.
- assemble-index pre-assembly frame guards: auto-repair a sub-comp root missing
canvas dims; hard-fail on <video>/<audio> inside a sub-comp; hard-fail on a
timed non-root element missing class="clip" or overlapping same-track clips.
- Lint/CLI: lint media inside sub-compositions as an error; stop false-positive
caption layout/lint findings; contrast/layout-audit skip elements hidden by an
invisible ancestor.

* fix(skills): clear CodeQL alerts in assemble-index.mjs
- script/style blanking regex now matches closing tags with trailing
whitespace (</script >, </style >) — js/bad-tag-filter (high).
- drop the existsSync precheck before reading/repairing a frame file; read
directly and handle ENOENT, removing the check->write TOCTOU window —
js/file-system-race (high).

* fix(core): a global gsap.set is off-timeline, so resolvedStart is 0 not the comp end
resolveTimelinePositions walks anims in document order advancing a cursor; a
global `gsap.set(...)` carries no position arg, so it fell through to the
cursor fallback and inherited the comp-end time (every prior tween's duration
summed) as its resolvedStart. A global set is a load-time hold — its start is 0.
This silently broke 'Enable keyframes' on any element whose only animation is a
global gsap.set (e.g. a statically-positioned card): promoteSetToKeyframes bails
when `playhead <= setStart`, and setStart was the comp end, so any playhead
before the end was a no-op. Pin a global set to resolvedStart 0 in both the
recast and acorn parsers; don't let it advance the cursor/prevStart.
* fix(studio): Enable-keyframes marks the generated 0% endpoint as auto-tracking
When 'Enable keyframes' promotes a static set to a two-stop tween, the 0% (the
held start the user didn't choose) is now marked `auto: true` → serialized as the
`_auto: 1` marker. The parser's endpoint-sync then keeps it tracking the nearest
keyframe until the user edits it directly; the 100% (the real keyframe placed at
the playhead) stays fixed.
This re-wires the auto-endpoint behavior that was silently dropped in #1605 (the
sync logic stayed, but no flow produced an `_auto` endpoint anymore, so an
untouched 0% never tracked). Adds a guard test so it can't be lost again.
* chore: suppress fallow complexity findings surfaced in the touched files
The resolveTimelinePositions guard added a branch (pushes it over threshold), and
changed-file scope re-surfaces pre-existing complex functions (readElementPosition,
applyArcWaypointAtPlayhead, the useEnableKeyframes callback). Bare directives only.
* fix(studio): dragging a --hf-studio-offset element no longer flies
Dragging a static element positioned via the legacy --hf-studio-offset CSS var
(e.g. dot-a) flew off-screen — three independent failure modes, all fixed:
1. Live drag integrated: the per-move draft read its base from the live transform
it set last frame (gsap.getProperty), so base+delta accumulated frame-over-frame.
Fix: carry a stable baseGsap on the in-memory drag member (immune to mid-drag
re-renders that wipe the data-hf-drag-* attrs) and use it as the fallback.
2. Commit re-added the delta: the source commit re-read the wiped attrs / live
transform. Fix: re-stamp the stable base/initial attrs in applyManualOffsetDragCommit
before the commit reads them.
3. Drop left it offset: the committed source was correct, but the LIVE element kept
its --hf-studio-offset var + translate:var(...), which composed with the GSAP
transform (rendered at dropped + offset) until a full reload. Fix: on cleanup,
when GSAP owns the position, clearStudioPathOffset() migrates the element off the
legacy CSS channel (leaving transform untouched) — matching the stripped source.
Adds a regression suite covering all three layers.
* fix(core): lint leaked head text in compositions
* fix(core): harden leaked head text lint
* chore: refresh code scanning status
* fix(core): cover parser-error head close tags
Renders showed the page background (a one-frame black flash) right before a cut
when a video clip's source media was a hair shorter than its data-duration slot
— the common case, since `ffmpeg -t 1.45` emits 43 frames = 1.433s at 30fps.
The frame lookup only held the last frame at the exact clip end, so the
sub-frame remainder rendered blank.
- Hold the last extracted frame for the rest of the slot once the source is
exhausted, within a tolerance floored at the compiler's 0.05s clamp epsilon so
the seam is covered at any fps (2 frames alone is < 0.05s above 40fps). Clips
deliberately much shorter than their slot still blank for the tail (unchanged).
- Warn when the compiler clamps a video's data-duration down to its media length
(slot longer than source by more than the clamp epsilon): a render-time
`[compile]` warning in the producer, plus a matching `validate` warning that
reads each <video>'s live duration in headless Chrome (static HTML lint can't
see media durations). A shared `analyzeClipMediaFit` keeps both on one
threshold.
Adds engine unit tests for the hold behavior and the analyzer.
* feat(studio): draggable 3D-transform cube in the design panel
Add a Figma-style draggable cube to the 3D Transform section so users can set an
element's 3D orientation by dragging instead of typing degrees. Drag tilts the
element (rotationX/Y); Shift-drag rolls it (rotationZ); a recenter button resets
the 3D transform to identity. The cube previews the orientation live and commits
on release.
It's an input affordance over the existing keyframe-aware commit path
(commitAnimatedProperty) — a drag at the playhead writes/updates keyframes just
like the numeric fields, no new mutation infra.
- transform3dProjection.ts: pure unit-cube projection with back-face culling and
painter ordering (no 3D dependency), unit-tested.
- Transform3DCube.tsx: the SVG drag widget (pointer-capture, draft→commit).
- Surface the two missing numeric fields (RotZ, Perspective). Perspective drives
the new editable `transformPerspective` prop (per-element depth) rather than
CSS `perspective` (which only affects children).
* feat(studio): polish 3D cube — collapsed by default, compact lit cube, live drag preview
Address review of the first cut:
- 3D Transform section is now collapsible and collapsed by default (it was tall
and ate panel space).
- Redesign the cube: compact and centered (was full-width), resting isometric
camera so it reads as a 3D cube at identity instead of a flat square,
directional per-face lighting, gradient backdrop + grounding shadow.
- Live element preview while dragging: onLivePreviewProps gsap.sets the live
transform on the preview element so it moves WITH the cube; release still
commits via the keyframe-aware path.
- Extract Cube3dControl to keep the panel component under the complexity gate.
* fix(studio): persist static 3D transform + refine cube edges
The cube (and the RotX/RotY numeric fields) didn't stick on an element whose
only tween is a position 'set' — commitAnimatedProperty tried to convert the
zero-duration hold into keyframes, so the rotation was never written and the
cube snapped back. Handle the static-set case: merge the property into the set
(update-property) so a static 3D rotation/perspective persists, and the cube
reads it back from runtime.
Also refine the cube rendering: muted teal lit faces with edges that brighten
with how front-facing each face is (crisp bevels, not flat neon outlines), a
soft halo glow, and a stronger grounding shadow.
* feat(studio): 3D transform — keyframe diamonds, flash-free commits, in-cube perspective
- Keyframe diamonds: RotX/RotY/RotZ + Perspective (and Z/Scale) now each carry a
KeyframeNavigation diamond, so 3D transforms can be keyframed like Layout X/Y.
Refactored the six fields onto a shared Transform3dField.
- Flash-free: static-set 3D commits now use instantPatch (in-place runtime patch,
no soft reload), and the set fast-path was widened to the 3D channels
(rotationX/Y/Z, z, transformPerspective) — dragging the cube / scrubbing a 3D
field no longer flashes.
- In-cube perspective: a Persp slider lives in the cube widget and the cube's
foreshortening reflects transformPerspective live.
* feat(studio): 3D cube X/Y/Z axis gizmo + gated flash-diagnostic logs
- Axis gizmo: render the rotated X (red) / Y (green) / Z (blue) vectors from the
cube center — away-facing axes dimmed behind the cube, toward-facing on top
with a tip dot + label — so orientation is readable at a glance.
- Flash diagnostics: add a gated, JSON-stringified [hf-3d:*] logger (on in dev or
via window.__hfDebug). Instruments the commit path (which branch + picked
tween), the cube pose/axis commits, and — the key signal — applyPreviewSync's
instant-patch-vs-soft-reload decision (a soft reload IS the flash). Reproduce
with the console open to pinpoint any remaining flash to a specific commit.
* fix(studio): make the 3D cube mirror the element's orientation 1:1
The resting isometric camera made the cube always look tilted, so at rotation
0/0/0 the cube showed a 3D pose while the element was flat — the cube didn't
represent the element. Drop the decorative camera (VIEW_RX/RY = 0): the cube now
faces front at identity, exactly matching the un-rotated element, and tilts to
match as the element rotates. The X/Y/Z axis gizmo keeps the flat-at-rest state
readable.
Flash status (from the gated [hf-3d:*] logs): every commit now reports
'instant (no flash)' via instantPatch — the soft-reload flashes are resolved.
* fix(studio): stop design-panel flicker — read transform channels live
Each 3D commit bumps the gsap cache; the panel then re-read runtime values, but
readGsapRuntimeValuesForPanel only included props already present in the parsed
gsapAnimations. A just-set rotationX isn't in the parse yet, so for that window
the cube + fields dropped it and flickered to 0. Always read the core transform
channels (x/y/rotation/rotationX/Y/Z/z/scale/transformPerspective/opacity)
directly via gsap.getProperty — which reflects the in-place instant patch — so
the panel shows the true current value with no flicker.
* refactor(studio): extract collectPanelPropKeys to keep panel reader under complexity gate
* feat(studio): keyframable 3D transforms — convert a static set to keyframes
The cube/3D fields stored rotation as a static 'set', and convert-to-keyframes
flatly refused to convert a set (gsapParser.ts) — so two 3D 'keyframes' just
overwrote the same static value with no interpolation.
Now a set converts to an animatable to(): resolveConversionProps emits both
endpoints from the set's value (visual unchanged until edited), and both writers
flip set→to, drop the immediateRender hold, and add a duration. The element's
clip duration is threaded through the convert chain (3D field → handler →
convertToKeyframes → route → parser) so the keyframes span the whole clip and
land in range at any playhead. Click a 3D field's diamond to convert, then edit
at different playheads to animate. Acorn writer mirrored; recast round-trip test
added.
* feat(studio): keyframe toggle on the 3D cube
The cube had no keyframe affordance, so dragging it only ever wrote the static
set (logs showed every rotation commit as path:static-set) and nothing
interpolated — converting required clicking a numeric field's diamond, which
isn't discoverable while driving the cube.
Add a keyframe diamond button to the cube widget: it converts the 3D
('other'-group) static set to keyframes spanning the element's clip, and lights
up when the transform is already keyframed. Once keyframed, cube drags + numeric
edits add keyframes at the playhead and the 3D rotation interpolates.
* feat(studio): auto-keyframe 3D transforms on animated elements + stop AssetsTab 404 loop
3D transforms now auto-keyframe like drag/resize/rotate: when the element is
already animated (its clip has keyframes), editing a 3D prop converts the static
set to keyframes so edits at other playheads interpolate — no manual keyframe
toggle needed. Purely static elements still write a static set (and the cube's
keyframe button remains a manual opt-in for them).
Also fix the AssetsTab media-manifest fetch: it was keyed on the assets array
reference (new each render) so it re-fetched the (usually missing) manifest on
every re-render — spamming 404s and churning the left sidebar during cube drags.
Key on a stable join and cache the 404 so a missing manifest is fetched once.
* fix(studio): cube writes one keyframe per drag (no duplicate keyframes)
The cube committed rotationX/Y/Z as separate add-keyframe mutations; the first
axis's auto-keyframe convert shifted the tween so the second axis computed a
slightly different percentage → two adjacent keyframes instead of one.
Add a batched commitAnimatedProperties that writes all changed props into ONE
keyframe, and route the cube through it (commitAnimatedProperty is now a thin
single-prop wrapper). Threaded through the panel chain; numeric fields keep the
single-prop path. Set-path and keyframe-path extracted to helpers to stay under
the complexity gate.
* refactor(studio): extract AudioRow from AssetsTab to satisfy file-size check
The manifest-404 fix touched AssetsTab.tsx, which was already over the 600-line
cap (702). Move the self-contained AudioRow sub-component to its own file,
bringing AssetsTab to 493 lines.
* fix(studio): self-heal stale animationId on 3D property commit
A 3D property edit (cube drag / field) picks its target from the panel's
selectedGsapAnimations cache. When keyframes were just removed or the script
changed underneath, that id is gone server-side and the commit POST 404s
('animation not found'). The raw commitMutation already toasts but rethrows,
so the rejection escaped as an uncaught promise. Catch it in
commitAnimatedProperties and bump the cache so the panel re-syncs and the
next edit self-heals.
* fix(studio): batch the 3D reset into one commit (was six flashes)
Reset 3D orientation looped six props (rotationX/Y/Z, z, scale,
transformPerspective) through the single-property commit, so one click
triggered six separate soft-reloads — six preview flashes. Batch them into
one onCommitAnimatedProperties call (one keyframe, one reload), matching the
cube-drag path.
* fix(studio): 3D-edit a static element writes a set, not keyframes
Editing the 3D transform of an element with no keyframes created a keyframed
tween (Case 3 made a tl.to() + convert, a flat tween converted to keyframes).
A static element should stay static — same as manual drag / resize / rotate,
which tl.set() it. Route no-keyframe elements to a set: update an existing one
in place, or create a dedicated tl.set carrying all axes in ONE add mutation.
The single mutation also avoids the per-axis id race (a flat tween's
group-derived id shifts after the first prop, 404-ing the next and polluting
an unrelated tween).
* feat(studio): instant 3D keyframe edits via in-place tween rebuild
Dragging the cube on an animated element soft-reloaded the iframe on every
edit (a flash). GSAP compiles object-form keyframes ({ "0%": {...} }) into
sub-tweens at creation and ignores later vars.keyframes mutations, so the value
can't be patched the way a tl.set can. Instead REBUILD the tween in place: kill
it and recreate it on the same parent timeline at the same position with the
edited keyframe merged and all other vars preserved, then re-seek — no iframe
reload, no flash. Resolution is now channel-aware for keyframe tweens too, so a
rotation edit lands on the rotation tween, never a co-located position tween.
Declines (→ soft reload) for array-form, motionPath, or dynamic values.
* feat(studio): static 3D transform persists as off-timeline gsap.set (no 0% keyframe)
Adjusting a 3D transform on an element with no keyframes created a
tl.set(...,0), which the timeline renders as a 0% keyframe diamond — even
though it's a static hold, not animated. Persist a newly-created static 3D
hold as a base gsap.set(...) instead: it runs immediately, sits OFF the
timeline, and shows no keyframe marker (matching the manual-drag UX).
- Model: GsapAnimation.global marks a base gsap.set vs an on-timeline tl.set.
- Parser (recast + acorn): parse a STRING-LITERAL gsap.set("#sel", {...}) as an
editable global set so it round-trips and re-edits in place; variable-target
gsap.set(el, ...) holds stay opaque surrounding source (unchanged).
- Serializer + writers: emit gsap.set(sel, props) (no timeline var, no position)
when global; in-place updates keep it a gsap.set.
- add mutation gains global; commitStaticSet sends it when creating a holder.
* fix(studio): static manual drag persists as off-timeline gsap.set, instant (no flash/diamond)
After keyframes are removed, manually dragging a now-static element wrote a
tl.set(...,0) — an on-timeline hold that shows a 0% keyframe diamond and
soft-reloaded on the first nudge (a flash/teleport between the overlay and the
committed position). Make the static position/rotation drag persist as a base
gsap.set (off-timeline, no marker), like the 3D path.
A gsap.set has no runtime tween to patch, so add a 'global-set' instant-patch
that applies the value straight to the element (gsap.set(el, props)) — the
element is static on these channels, so it reflects instantly with no soft
reload. Existing tl.set holds keep the tween 'set' patch; only global sets use
global-set. Create now carries the instant patch too, so the first nudge is
flash-free.
* fix(studio): a base gsap.set shows no keyframe diamond (timeline + panel)
A base gsap.set is parsed as an editable set (for idempotent re-edits), but
synthesizeFlatTweenKeyframes turned it into a synthetic 0% keyframe, so the
timeline track and the panel field showed a phantom keyframe diamond for a
static, non-animated value. Return null for a global set so it contributes no
keyframes — it's an off-timeline static hold, not a keyframe.
* fix(studio): a static set never shows a keyframe diamond (timeline + panel)
A set (gsap.set OR tl.set) is a static hold — a value applied at one point,
not an animated keyframe — so it must not synthesize a phantom keyframe. The
prior fix only skipped GLOBAL gsap.set; on-timeline tl.set holds (and ones a
split/conversion produced) still showed a diamond. Skip every set, which also
aligns the AST keyframe cache with the runtime scan (it already drops every
zero-duration set).
* fix(studio): batch set-property edits (reset 3D no longer 404s)
Reset 3D fires 6 props (rotationX/Y/Z, z, scale, perspective) at a set;
commitSetProps updated them one at a time. A set's id is GROUP-derived, so the
moment scale lands on a rotation set its id shifts (-other -> mixed), 404-ing
the next prop (perspective never got set). Add an update-properties mutation
(merge many props in one call) and have commitSetProps/commitStaticSet use it —
one round-trip, no mid-loop id shift.
* style(studio): fix format + trim 3D-patch helper complexity
oxfmt the runtime-patch file (the failing Format/Preflight check) and reduce
the complexity of the new helpers: flatten keyframeVarsCarryChannel with .some,
extract finiteNumericProps from applyGlobalSet, suppress the inherently-defensive
rebuildKeyframeTween guard chain.
* chore(studio): remove [hf-3d:*] debug logs (3D transform verified working)
Strip the log3d call sites + the debug3d util now that the 3D transform /
static-set / keyframe-rebuild paths are confirmed working.
* chore(studio): strategic [hf-pos:*] logs for position-commit path audit
Temporary DEV-gated logs to confirm which path each drag takes: single drag →
GSAP code path (single-gsap), multi-select/group drag → DEPRECATED CSS-var path
(group-css, applyStudioPathOffset → --hf-studio-offset), and the single CSS
fallback (single-css). To be removed once group drag is routed through GSAP.
* fix(studio): route multi-select group drag through GSAP code path
Group drag committed positions via the deprecated --hf-studio-offset CSS
var (applyStudioPathOffset) and outright blocked GSAP-animated elements.
Single drag already routes through tryGsapDragIntercept (tl.set /
keyframes / gsap.set); group drag now does the same per element, so a
multi-select move writes real GSAP code with no CSS-var fallback. Removed
the now-dead CSS group commit.
* feat(studio): live candidate highlight while marquee-selecting
The marquee only revealed what it selected on mouse-up, so it was easy to
grab too much or too little. Now each element the marquee box currently
intersects is outlined live (studio-accent) as you drag, before release —
so you can see the selection forming. Shares one synchronous OBB/SAT
intersection pass between the live highlight and the commit; the async
source-probe still runs only once, on mouse-up.
* chore(studio): remove temporary [hf-pos:*] position-path debug logs
Investigation done — group drag now routes through the GSAP code path, so
the CSS-vs-GSAP path-audit scaffolding (logPos / debugPos) is no longer
needed. Removes the util and its imports/calls.
* fix(studio): marquee selects/highlights elements at their real positions
The marquee derived element boxes from elementObbCorners, whose
non-identity-transform branch reconstructed the box from offsetLeft/offsetTop
plus the element's own transform matrix — ignoring the matrix translate
(m.e/m.f) and any ancestor transforms. Mid-GSAP-animation (elements carry a
translate() transform), that put boxes at their pre-translate layout
position, so the marquee highlighted/selected the wrong elements vs. the
box shown when you click an element directly.
Route the marquee through the same toOverlayRect basis the selection and
group boxes use (a getBoundingClientRect-based AABB). Now highlight ==
selection-commit == the click-selection box, at the element's real on-screen
position. Drops the buggy OBB/SAT path (elementObbCorners,
marqueeIntersectsObb); AABB matches the selection box, which never rotated.
Adds dev-only [hf-marquee:*] tracing (per-element rect + intersect + skip
reason, JSON) to debug what the marquee sees; stripped from prod builds.
* fix(studio): off-canvas elements no longer render a selection-style border
OffCanvasIndicators drew two layers per partly-off-screen element: a dashed
sliver on the protruding part, plus a solid studio-accent border (with the
selection box-shadow) over the on-canvas portion. That solid border only
ever draws for UNSELECTED elements (selected ones get a real selection box
via the filter), so an unselected off-canvas element looked selected.
Removed the solid inside layer — the dashed protruding sliver stays as the
off-canvas hint.
* chore(studio): remove [hf-marquee:*] debug logs
Marquee position fix is verified; strip the dev-only tracing scaffolding
(logMarquee/debugLabel/debug param) back to the lean intersection loop.
* fix(studio): convert a global gsap.set to a seekable timeline tween + review cleanups
Primary fix: converting a global `gsap.set` to keyframes flipped only the
method (set->to), leaving the callee object `gsap` — emitting `gsap.to(...)`,
an off-timeline tween that fires once at load and isn't on the paused master
`window.__timelines` (the engine can't seek/render it). Reachable from the
cube's keyframe toggle + maybeAutoKeyframeSet on the global sets commitStaticSet
creates. Now re-roots onto the timeline var and adds the position arg, in both
the recast and acorn writers; covered by a convert test seeded from gsap.set in
each path.
Review cleanups: drop dead confirmDelete/<DeleteConfirm> in AudioRow; drop the
always-zero viewRx/viewRy camera params from the 3D projection; un-export four
internal-only symbols (clears fallow unused-exports); re-add the collectMarqueeHits
complexity suppression dropped with the debug scaffolding.
* chore(studio): green the CI gate + 3D panel expanded by default
- File-size: extract the marquee/candidate render into MarqueeOverlay so
DomEditOverlay drops back under the 600-line cap.
- Fallow complexity: suppress the 8 accepted-complexity findings from the 3D/
runtime work (resolveRuntimeTween, readRuntimeKeyframes, hasNonHoldTweenForElement,
commitKeyframeProps, scored, ImageCard, selectionShapeStyles, off-canvas effect)
with the bare directive the linter recognizes.
- 3D transform panel now defaults to expanded (the cube gizmo is the headline).
* feat(slideshow): per-slide autoplay (manual-advance, opt-in)
Adds an opt-in `autoplay` flag to slideshow slides: when the presenter lands
on a video slide, its `<video>` plays from the start. The slideshow still
holds and never auto-advances — the presenter clicks Next when ready. This
covers compositions whose own controls can't be clicked (the player renders
the composition pointer-events:none).
Plumbing (done, tested):
- core: `SlideRef.autoplay?: boolean`, parsed + validated in parseSlideshow
(a non-boolean autoplay rejects the manifest); carried through resolve.
- controller: optional `PlayerPort.playSceneMedia(sceneId)`, fired only on
forward `enterSlide` for autoplay slides (not resume/back/sync, so the
audience — which mirrors the presenter's media events — isn't double-driven).
- component: `playSceneDocumentMedia` reaches the same-origin composition
iframe, finds the scene's `<video>`, and asserts playback; `stopMedia`
(already wired on slide change) resets it. An autoplay token cancels a
pending start when the slide changes.
- tests: controller autoplay behavior + parser flag round-trip/validation
(131 player + 22 core slideshow tests pass).
KNOWN LIMITATION — runtime media-start needs the player media model (@vance):
On current main the clip<->timeline binding from #1601 keeps every clip synced
and *paused* to the held timeline frame, which wins against playSceneMedia's
play() — so the clip does not actually start on main yet (it does on the
pre-#1601 player). The correct fix is a sanctioned "let this clip free-run
while the timeline holds" path in the player/runtime media controller. Flagging
for Vance to wire the start into the #1601 media model (or rebase onto it) when
back. The plumbing above is the stable surface that hook plugs into.

* refactor(slideshow): address code-review on per-slide autoplay
- guard playSceneDocumentMedia behind resolveMode() !== "audience": the
audience mirrors the presenter's media events, so it must not independently
drive its own copy of the clip.
- drop the per-enter window pointerdown/keydown "gesture retry" listeners,
which leaked when muted autoplay succeeded without a gesture. The poll already
re-asserts play(), so a gesture within the window is picked up next tick.
- stop polling once the clip is advancing across two ticks (was re-asserting
play() for the full window even after playback was confirmed).
- cancel any in-flight autoplay loop on disconnectedCallback (bump the token).
- split the poll into findSceneVideo + stepAutoplay helpers (keeps each small).
- fix the enterSlide comment: autoplay fires from enterSlide (next/prev/
goToSlide), not resumeSlide (back/backToMain/syncTo).
- parser: isOptionalBoolean type guard instead of a one-off helper; drop `as`
assertions in the new controller test.
131 player + 22 core slideshow tests pass; lint/format/typecheck/fallow clean.

* docs(slideshow): autoplay skill guidance + address review nits
Addresses review feedback on #1708:
- skill: document per-slide `autoplay` in the slideshow standalone-harness
reference — when to use it (video is the slide's primary content, its end is
the advance cue) vs not (background/ambient loops, footage talked over), per
Vance's guidance, before merge.
- play() rejection is no longer blanket-swallowed: AbortError (timeline-sync
seek interrupt) and NotAllowedError (gesture-gated autoplay) are expected and
ignored; any other rejection is surfaced once via console.warn (Via nit 1).
- clarify in the SlideRef.autoplay doc that it plays the scene's FIRST <video>
(Via nit 2).

Speed-curve editor: a fixed-square cubic-bezier graph (grid, linear reference,
draggable handles, live preview) for editing eases; conventional preset grid.
Class/selector tweens: attribute `gsap.from(".dot", …)`-style tweens to every
matching element so they surface in the inspector and keep their timeline
keyframe diamonds when the clip is selected.
Apply-to-all easing: a "Set all…" control sets easeEach and strips every
per-keyframe ease override in one mutation (AE select-all + F9). Implemented in
BOTH gsap writers — the acorn writer and the recast writer (the default server
path); the recast side was missing resetKeyframeEases, so "Set all" set easeEach
but left per-keyframe eases in place.
Per-keyframe size: resizing an animated element writes a width/height keyframe
at the playhead — other keyframes keep their size — instead of a global
gsap.set hold; static elements keep the simple global resize. The extra size
tween exposed a motion-path bug (the overlay read whichever tween contained the
playhead), fixed with an opt-in requireChannels filter so the path only reads
the positional tween.
Inferred Timing: derive Start/End/Duration from an element's animations when it
has no authored clip range, instead of showing 0.00s.
Ease labels now surface the raw GSAP token (power2.out, back.out, …) instead of
invented names ("Smooth slowdown") that confused authors.
Also pass the preview iframe to the inspector's animation hook so element
resolution runs, and remove the unused editDebugLog facility.
Studio/preview stamps `data-start` onto ID'd and GSAP-targeted flow
children (eg. a <header>/<footer> in a flex column) so the design panel
can discover them. applyClipLayout then force-absolutized those stamped
elements as if they were authored overlay clips, collapsing the layout:
the footer shrink-wrapped and its `justify-content: space-between`
clustered into the top-left, while the rendered video — which never
stamps (production renders run as the top-level page, not in an iframe) —
stayed correct.
Mark runtime-stamped clips with `data-hf-autostamped` and skip them in
applyClipLayout so they remain in document flow. The preview now matches
the rendered video (true WYSIWYG). Authored overlay clips are unchanged,
so the golden regression suite is unaffected.
* chore(studio): remove all console.* calls from studio package
* chore(studio): address review — remove dead stubs, restore consent notice
- Delete empty if-blocks left after console removal (snapTargetCollection,
Player asset-poll, useTimelineSyncCallbacks 5s probe, useGestureRecording
dev guard + now-unused isDevBuild) and the stale "surface in dev" comment.
- Drop the dangling no-console pragma + dead duplicate-id branch in sourcePatcher.
- Restore the one-time telemetry consent disclosure in showNoticeOnce (kept
behind a pragma — it is a user-facing notice, not debug noise).
- Remove the missed timelineIcons console.warn while preserving the
`tag || "div"` null-safety fallback.
- Route caption auto-save failures (a data-loss path) through telemetry
instead of swallowing silently.
- Restore the accidentally-clobbered css-var-fonts output.mp4 fixture.

* fix(runtime): immediateRender for set tweens + array timeline normalization
- Set tweens now emit immediateRender:true so they render on page load
without requiring the runtime to seek past position 0
- Runtime IIFE normalizes array timelines (window.__timelines = [tl])
to keyed objects, and auto-adds data-start on root elements
- Drag teardown clears translate:none to prevent #1673 fly-off
- Position-only set tweens hidden from timeline diamonds (3 cache paths)
- Parser: ease-only keyframe update preserves existing properties
* fix(runtime): address review — restore perf gate, debug surface, scrub restore
- Restore the #1651 skipForInjectedVideo gate in media.ts that was dropped on
restack — avoids ~2400 wasted per-tick seeks on video-heavy renders.
- Restore the console.debug body + docstring bullet of swallow() in
diagnostics.ts: the __hfDebug opt-in debug surface had been gutted to an
empty if-block.
- Rebind: after the progress-cycle set() kick, seek to state.currentTime via
totalTime() instead of snapping to 0, so a rebind after scrub / soft-reload
restore keeps the playhead.
- Array __timelines normalization + data-start default now resolve the root
via a shared findRootCompositionEl() that honors data-root="true" first
(matches resolveRootCompositionElement, which now delegates to it).
- Ease-only keyframe update leaves a primitive (non-object) keyframe value
untouched instead of wiping it to {}; add a preservation unit test.
- Document the boundDuration<=0 progress(1) kick + restore the STATIC-case
comment in gsapRuntimeBridge.

* 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.

* 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).

## What
Studio preview now resolves `<video src="../../assets/x.mp4">` (and the
same shape for `<img>`, `<audio>`, inline `style` `url()`, and `<style>`
CSS `url()`) against the sub-composition's URL — matching what the
server-side bundler already does for the render path.
## Why
Authored compositions live at `compositions/frames/*.html` and reference
project-root assets either as plain `assets/x.mp4` (already correct
because the main document's `<base href>` points at the project preview
root) or as `../../assets/x.mp4` (the explicit project-root-relative
form). The server-side `inlineSubCompositions` flattens sub-comps into
`index.html` and rewrites the `../`-form against the sub-comp's source
path so it resolves against the project root in the baked render.
The browser-side runtime that mounts external sub-compositions via
`fetch` did no such rewriting. So `<video src="../../assets/x.mp4">`
authored inside a `compositions/frames/scene.html` resolved against the
main document's base href, climbed above the project root, and 404'd in
Studio preview — even though the same path rendered correctly in the
final video. An OSS user (Miao Yang) hit this in a real project.
## How
Added `rewriteSubCompositionAssetPaths` to the runtime
`compositionLoader`. After parsing the fetched sub-composition HTML and
before extracting any nodes, walk the parsed document and rewrite the
same surface the server-side path touches:
- `[src]` and `[href]` attributes on every element
- `[style]` attribute `url(...)` references
- `<style>` element CSS `url(...)` references
The rewrite mirrors the producer's semantics exactly: only values that
start with `../` (or are literal `..`) are rewritten — against the
sub-composition's URL via `new URL(value, compositionUrl)`. Absolute
URLs, root-relative paths, `data:`, hash refs, and plain
`assets/x.mp4` are left untouched. **Plain relative paths must not be
rewritten** because the main document's `<base href>` already covers
them; rewriting would double-prefix the URL.
The walk recurses into `<template>` content because authored
compositions typically wrap their rendered body in a `<template>` and
`querySelectorAll` does not enter template content (it lives in a
detached `DocumentFragment`).
## Test plan
- [x] Unit tests added (6 new tests in
`compositionLoader.test.ts`): rewrites `../`-traversing src on
template-wrapped sub-comps; leaves plain relative paths untouched (no
double-prefix); leaves absolute / data / hash / root-relative URLs
untouched; rewrites CSS `url()` in `<style>` blocks and inline
`style` attributes; rewrites for non-template (full-HTML-doc)
sub-comps.
- [x] Full core test suite green (2065 tests).
- [x] Full studio test suite green (1148 tests).
- [x] Manual verification with the reporter's actual project:
before the fix one `<video>` with a `../../assets/...` src returned
`MEDIA_ELEMENT_ERROR: Format error`; after the fix all 7 `<video>`
elements load (`readyState=4`, correct `currentSrc`). The 6 plain
`assets/...` paths are *unchanged* (no double-prefix) and continue
to resolve via `<base href>` as before.
- [x] `bun run lint`, `bun run format:check`, `bun run typecheck`,
`fallow audit` all green.

Extract rootClassStyledSelectors so the subcomposition_root_styled_by_class
rule drops below the complexity threshold, and ignore the music-to-video
reference HTML (template + motion-primitive materials forked by path, not
import-graph reachable) — same treatment as motion-graphics/grounding.

Replace bgm-to-video, bgm-to-video-new, bgm-to-video-refactor, and the
standalone beat-sync/montage skills with a single music-to-video skill.

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.
