Miguel Angel Simon Sierra 8470b88aa1 fix(studio): settle boundary retimes, delete every keyframed tween, tighten the test locks
Review follow-ups on the expanded keyframe lanes.

Writer:
- `onMoveKeyframe`'s flat-tween boundary branch answered `true` the moment it
  dispatched update-meta, so a rejected write left the diamond parked at its drop
  position. `observeGsapMutation` now resolves to whether the mutation landed and
  the boundary branch returns it, matching the other branches.
- "Delete All Keyframes" cleared only the first keyframed tween on the layer, so
  a layer with position AND opacity keyframes kept half of them. It now walks
  every keyframed tween, serially, through the clicked element's selection.
- The post-convert lookup in `commitFlatViaKeyframes` matched by target selector,
  which picks an arbitrary tween when a target carries several. Match by id first.

Interaction and a11y:
- A rejected retime whose commit settled after a newer drag reverted the
  selection to its own source keyframe, undoing a retime the user could see. The
  revert now only runs while it is still the lane's latest gesture.
- Diamonds key on the authored identity instead of index plus rendered clip-%, so
  a neighbour's retime no longer remounts the button mid-drag.
- The disclosure caret gets `aria-controls` on an always-mounted lanes container,
  and both it and the property-group toggle grow to the 24x24 WCAG 2.2 minimum.
- `LayerDisclosureRow` takes the same adaptive `columnWidth` as its sibling lane
  rows instead of hardcoding LABEL_COL_W over the canvas.

Test locks:
- The timeline callbacks harness resolves a DISTINCT selection per element, so
  the clicked-element writes are actually pinned; three assertions that passed
  either way now name the clicked element's selection.
- New: null-selection aborts every mutation, delete-all covers both tweens, a
  rejected boundary retime reports `false`, and a stale revert leaves selection.
- The playhead-percentage assertion checks 25, not `expect.any(Number)` (which
  also accepts NaN); ease segments assert their label ORDER, not just that the
  three curves differ; the collapsed-diamond callback asserts the whole target.
- Dropped a duplicate `selection override` describe left by a rebase.

Miguel Angel Simon Sierra b8ff8bf0f3 fix(studio): close the review findings that survived the stack
Selector reads now go through one inverse of `idSelector`. Every writer emits
`[id="01-hook-hero"]` for an id a `#id` selector can't address, but the readers
still matched `#id` only, so the post-commit keyframe-cache refresh, the AST
load and the remove-all-keyframes clear all silently skipped exactly the ids
`idSelector` was added to support.

A keyframe merged from two tweens with different eases kept whichever ease
iterated last. Readers that don't check `easeAmbiguous` showed a curve from a
different animation than an edit would target, so the ambiguous flag now clears
`ease` instead of leaving an arbitrary one behind.

One tolerance for "the playhead is on this keyframe". The motion-path drag used
0.05% while the toolbar and the playhead apply used 1%, so a drag that landed a
fraction of a percent off an authored waypoint skipped the update-point branch
and appended a near-duplicate. `buildTemporalArcKeyframes` now owns the
invariant and replaces any keyframe inside the tolerance, rather than trusting
each caller's own pre-check.

The pending-retime bookkeeping matches on keyframe identity, not just on
"something is near that percentage" — an evenly spaced row cleared the entry off
an unrelated sibling. The neighbour clamp composes pending destinations in
before sorting, so a second drag can't cross a neighbour that already moved.

Also: `keyframeCache`/`gsapAnimations` setters return the same state for a write
that changes nothing (every no-op re-rendered every subscriber), the auto-expand
set drops clips that left the source so an undo/paste under the same id expands
again, `invalidateGsapCache` has a stable identity instead of re-creating the
whole timeline edit context each render, the studio test hook deletes its window
key rather than leaving it enumerable as undefined, and the past-last-row
extrapolation documents why it uses TRACK_H where the pre-first-row branch uses
row 0's own height.

Covers `idFromSelector` round-trips, the insert boundary band across plain,
expanded and unusable row heights, and the collapsed selection key for a
colon-bearing element id.

Miguel Angel Simon Sierra 282cc883e5 fix(studio): address family B timeline review findings
- revert diamond selection when a rejected retime leaves the source in place
- clear project-local ease focus and expansion on player store reset
- share one static-position-hold predicate across the tween cache
- invalidate the GSAP cache even when a group timing rewrite throws
- stamp each lane keyframe's ease from its own source tween
- memoize property lanes and row offsets so memo'd diamond lanes hold
- use the editable tween duration for drag position commits
- restore the pre-t=0 pad in the all-collapsed content origin
- clamp the drag ghost and drop placeholder to the collapsed clip height
- aria-expanded on the layer disclosure, aria-pressed plus state-specific
  labels on the keyframe toggle, 24px chevron targets, focus-visible parity

Miguel Angel Simon Sierra 62e866eda6 fix(studio): span the clip on the remaining duration-less tween paths
Two sibling call paths still answered from GSAP's 0.5s default while the
toggle path had moved to the clip-wide fallback.

isPlayheadWithinTween now takes the selection, so the toolbar stops
promising "extends animation" on a duration-less tween whose click actually
toggles an interior keyframe. The arc drag commit resolves its replacement
duration the same way its click-path sibling does, instead of authoring
duration 0.5 and collapsing the arc window.

The flat text section drops its two marker-clearing effects: the autofocus
marker is a ref now, read and cleared by the render that consumes it.

Miguel ÁngelandClaude Opus 4.8 adb40321d6 chore(studio): remove all console.* calls from studio package (#1691)
* 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.

Miguel Ángel 091137e3c3 feat(studio): instant, flicker-free manual editing (#1605)
* chore(producer): shim __filename/__dirname in the CJS banner

Bundled CJS deps like wawoff2 call __dirname; without the shim they throw
"__dirname is not defined in ES module" at render time. Also ignore .zed/.

* chore(producer): use a template literal for the CJS banner (review nit)

* feat(core): add GSAP keyframe + motion-path source mutations

Array-form keyframe removal in both the recast and acorn writers, plus
update/add/remove-motion-path-point and add-motion-path. Exclude _auto and
data from tween property-group classification.

* fix(core): address #1554 review — data-exclusion test, split-fix doc, motion-path sentinel, parity blocks

- Regression test for the `data` GSAP-key exclusion (parallel to _auto).
- splitAnimationsInScript: documented that .fromTo()/.to() correctly stay out of the
  from-branch (only .from() reverts) and the <= boundary; added mid-flight straddle tests.
- addMotionPathToScript failure path returns id: null (was empty-string sentinel); caller updated.
- Parity blocks for addKeyframeToScript array-form + updateKeyframeInScript (mirroring
  removeKeyframeFromScript). Surfaced a latent acorn array-form partial-props merge bug —
  documented as it.skip with a ready assertion (acorn cutover follow-up).

* feat(core): route motion-path mutations through studio-api + fix clip stamping

Wire the new mutations into the file save route. Only authored clips suppress
descendant stamping, so auto-stamped animated scenes can inline-expand.

Hide in-flow timed clips with `display:none` only when they are LEAF clips (no
nested timed clips). `display:none` on a container removes its whole subtree,
hiding descendants that are still inside their own visibility window — e.g. an
in-flow composition root whose effective window clamps to the timeline end would
black out a child video that should still show (the hdr-hlg regression).
Containers keep `visibility:hidden`, which a visible descendant can override; only
leaves leave the flow, which is all the split-overlap case needs.

* feat(core): strip legacy path-offset/rotation + drop obsolete studio lint rule

A position or rotation add/set mutation makes the GSAP timeline the single source of
truth for that channel, so any lingering --hf-studio-offset / --hf-studio-rotation CSS
var must be cleared to avoid double-applying. stripStudioEditsFromTarget now clears both
channels, and the add-strip fires for the position AND rotation property groups.

Also removes the obsolete `gsap_studio_edit_blocked` lint rule: it warned that Studio
cannot save drag/resize edits to elements in a registered timeline — the exact premise
the single-source work inverts (the timeline is now the edit target). Removed the rule,
its now-unused TIMELINE_REGISTRY_ASSIGN_PATTERN import, and its 5 tests.

* fix(core): address #1555 review — complete hold-sync, invalidate clip cache, strip rotation channel

- HOLD_SYNC_MUTATION_TYPES: add add-motion-path (load-bearing — addMotionPathToScript
  authors past t=0 → first-frame snap-to-(0,0) without the hold), update-meta,
  shift-positions, scale-positions, split-animations. (add stays out: flat tweens
  only, syncPositionHoldsBeforeKeyframes is a no-op for non-keyframed tweens.)
- init.ts: timedClip in-flow/leaf WeakMaps now invalidate on clipTreeSignature change;
  visible/hidden branches both go through isTimedClipInFlow (was .get() by accident).
- keyframesWriteRotation mirrors keyframesWritePosition so a rotation-only keyframe set
  strips the stale --hf-studio-rotation channel.

* feat(studio): GSAP runtime read layer + shared helpers

* fix(studio): address #1607 review — cold-parse vs fetch-error budgets, isZeroDurationSet, array-ease tests

- useGsapAnimationFetchFallback: discriminate resolved/fetch-error/cold; only the cold
  (warm-but-zero) race gets the full ~600ms retry budget — a hard fetch error retries once.
- Extract isZeroDurationSet (was !(duration>0) duplicated); rejects NaN, documents intent.
- parsePercentageKeyframes: cite GSAP even-index spread; tests that a per-entry/interior
  ease is stripped without shifting the other keyframes' percentages.

* feat(studio): GSAP drag/commit/bridge editing infra

* fix(studio): address #1608 review — facade awaits commit, strict stale-parse guard, clearProps restore

BLOCKER: useSafeGsapCommitMutation now RETURNS the (.catch-chained) commit promise and the
commitMutation facade awaits it — so await session.commitMutation(...) resolves AFTER the
server save, fixing both consumers (useEnableKeyframes + useGestureCommit's
showToast/requestSeek/idle, which were firing before the save landed). SafeGsapCommitMutation
return type widened void→Promise<void> (fire-and-forget consumers ignore it).
- stale-parse guard uses hasNonHoldTweenForElement (a leftover hold set no longer counts as live).
- commitFlatViaKeyframes snapshots dragged gsap values before clearProps + restores after seek,
  so a failed commit leaves the dropped pose, not a cleared element.

* feat(studio): motion-path geometry + commit helpers

* docs(studio): address #1609 review — document occlusion fade-in invariant, donut limit, nearestPointOnPath t-semantics

* feat(studio): on-canvas motion-path overlay

* fix(studio): address #1610 review — scope dblclick to pan-surface, kind-aware geometry guard, gate createMode, screen-space drag threshold

* feat(studio): keyframes flag, gesture recording + timeline/selection refinements

* fix(studio): address #1611 review — fetch-first keyframe path, gated hydration, dev-gated debug + gesture warn, per-group gesture tweens

- useEnableKeyframes: parse current source first (null-vs-[] distinction) so a delete-all's
  empty parse isn't overridden by a stale selectedGsapAnimations cache.
- useStudioUrlState: freeze the hydration effect's time dep once hydrated (was re-running every tick).
- useGestureRecording: dev-gated console.warn when the live-preview runtime throws (was silent).
- playerStore: gate window.__playerStore behind dev (guarded import.meta.env.DEV).
- useGestureCommit: partition recorded keyframes by property group → one add-with-keyframes per
  group, so a mixed gesture no longer yields an untagged legacy tween.

* feat(studio): single-source manual offset + rotation via the GSAP timeline

Dragging or rotating an element writes into the GSAP timeline (the single source of
truth) instead of a parallel --hf-studio-offset / --hf-studio-rotation CSS var: static
elements commit a tl.set (idempotent on re-edit), tweened elements edit keyframes, and
the live preview moves via gsap.set so what you see equals what is written and renders.
Removes the dual-channel CSS-var/transform reconciliation behind the
fling / disappear / runaway / double-stack / wrong-start bug class — for BOTH position
and rotation (gesture base read from the gsap transform, gsap.set live preview, tl.set/
keyframe commit, dropped the handleDom*Commit CSS fallbacks).

Subcompositions edit the same single-source way, which surfaced and fixes:
- resolve a subcomp element's source file via the composition-id map (the runtime drops
  the source linkage when inlining the subcomposition);
- a selected element's selection box AND motion path use basic visibility, not the
  occlusion heuristic (a backgroundless opacity-1 scene above it is not an opaque cover);
- soft reload rebuilds ONLY the committed composition's timeline, leaving other
  compositions' timelines intact (no cross-composition revert);
- read keyframes from the element's OWN composition timeline (scan all timelines, not
  the first unstable key);
- delete-all uses a soft reload too, so editing no longer hard-reloads the iframe.

* fix(studio): address #1567 review — drop drag-intercept flag, harden softReload onerror, tighten runtime ladder, per-group gestures

- DROP STUDIO_GSAP_DRAG_INTERCEPT_ENABLED: single-source GSAP intercept is the only
  position/rotation channel; the false branch silently killed drag+rotate (and let GSAP
  elements into the keyframe-corrupting CSS path). Removed flag + dead branch + env def + tests.
- gsapSoftReload: plugin onerror no longer fakes success — signals onAsyncFailure so the caller
  full-reloads; honors __hfMotionPathPluginLoading so a concurrent reload can't queue a dup script.
- gsapDragCommit: resolveDragRuntime narrows the as-any ladder; a mid-seek throw logs + drops
  partial reads (no phantom identity) and re-applies the drag override in finally.
- MotionPathOverlay: park-timer cleanup keyed on animId change.
- useGestureCommit: partitionKeyframesByGroup wraps the add-with-keyframes sites (per #1611 review).

* feat(studio): patchRuntimeTweenInPlace — update a tween's values in place

Defensive runtime helper: locate the element's tween in window.__timelines via the
shared resolveRuntimeTween scan, update its set/keyframe vars, invalidate, and re-seek
the playhead — without re-running the whole composition. Returns false (caller falls
back to soft reload) for any shape it can't safely patch (no tween, dynamic/computed
keyframes, motionPath arc, channel mismatch, or any error). Foundation for instant,
flicker-free manual edits.

* fix(studio): address #1612 review — channel-aware set resolution + decline dynamic-expression patches

- resolveRuntimeTween gains an optional channels[] hint; for kind:set it prefers the set whose
  vars carry one of the patched channels and never returns a disjoint-only set (e.g. won't write
  {x,y} into a co-located {rotation} set). patchRuntimeTweenInPlace derives channels from the props.
- patchSet declines (returns false → soft reload) when overwriting a string/dynamic vars[ch],
  instead of silently dropping the computed expression.

* feat(studio): instantPatch fast path in runCommit

A commit carrying an instantPatch option tries patchRuntimeTweenInPlace first; on
success the preview updates in place with NO reload (instant), on false it falls back
to the existing soft reload. Extracts the preview-sync tail into a testable
applyPreviewSync helper. No behavior change when instantPatch is absent.

* feat(studio): route static position/rotation set drags through instantPatch

Static-element position and rotation set commits now attach instantPatch{selector,
change:{kind:set}} so the drag updates in place with no reload. Structural ops (new
tween add, delete-all, convert/split/materialize) and keyframe edits deliberately omit
it and keep the soft reload — keyframe instant-patch needs object-form keyframe support
in patchRuntimeTweenInPlace (deferred).

* fix(studio): address #1613 review — derive instantPatch from the mutation, patch both coalesced commits, wire onAsyncFailure

- commitStaticGsapPosition/Rotation derive instantPatch.change.props from the actual
  update-property mutation(s) sent (one source of truth → findUnsafeMutationValues-validated
  values flow into the patch; can't drift).
- Coalesced x/y: the intermediate x commit also carries instantPatch{x}, the y commit {x,y},
  so a second-POST failure still leaves the preview patched for what persisted.
- applyPreviewSync passes reloadPreview as onAsyncFailure (plugin-CDN load error → full reload);
  per U4 the synchronous false still does NOT escalate.
- (channel disambiguation from #1612 verified end-to-end: {x,y}→position set, {rotation}→rotation set.)

* feat(studio): no full iframe remount for soft-reloadable edits

A softReload edit (and the SDK single-script refresh) no longer escalates to a full
reloadPreview() iframe remount when applySoftReload returns false — the live gsap.set
already shows the value, and a remount is the worst flash + re-inlines subcomps
(reverting their keyframes). verifyTimelinesPopulated now checks the expected target
keys the re-run registers, so a correct scoped re-run doesn't spuriously report empty.
Full reload stays only for the structural (no-softReload) and ambiguous-script paths.

* feat(studio): pre-load MotionPathPlugin so motion-path edits don't async-flash

ensureMotionPathPluginLoaded() runs once at the preview iframe-load seam (NLELayout
onIframeLoad), eagerly loading + registering MotionPathPlugin without killing the
timeline. So when a user adds a motion path to a composition that didn't originally
use one, the soft reload runs synchronously instead of taking the kill-then-await-CDN
async path (the flash). Idempotent + defensive; the existing async fallback stays for
genuine cold-start/CDN-failure.

* fix(studio): don't re-save + reload when source editor syncs externally

The SourceEditor's CodeMirror update listener fired onChange on ANY docChanged —
including the programmatic dispatch that syncs external content (e.g. a manual-edit
commit writing the source back into the open editor). That made the editor re-save the
file and bump refreshKey, fully reloading the preview iframe on every drag/keyframe
edit — defeating the in-place instant patch and causing the flash. Annotate the
programmatic sync (ExternalSync) and skip onChange for it, so only real keystrokes save.

* fix(core): inject MotionPathPlugin into preview when a composition uses motionPath

A studio-created motion path writes a gsap motionPath tween into the single-source
timeline, but the preview HTML only loaded gsap core — so the first render threw
"Invalid property motionPath ... Missing plugin?". Detect motionPath usage and inject
MotionPathPlugin right after the composition's gsap script, version-matched to it.

* fix(studio): dedup __hfMotionPathPluginLoading type decl (restack artifact)

* fix(studio): address #1605 review — distinguish soft-reload failure modes + observability, SourceEditor focus guard

BLOCKER: applySoftReload now returns SoftReloadResult ('applied' | 'verify-failed' |
'cannot-soft-reload') instead of a bare bool. applyPreviewSync + sdkRefresh escalate to a full
reloadPreview() on the PERMANENT 'cannot-soft-reload' (no gsap/rebind hook/scopable key/script,
or sync re-run threw) — fixing the silent-stale-preview U4 dropped — but still suppress the
TRANSIENT 'verify-failed' (live gsap.set is correct). Telemetry: gsap_soft_reload_outcome
(origin/result/escalated) + gsap_instant_patch_fallback, so the U4 invariant is enforced, not asserted.
- SourceEditor: skip the programmatic external-sync replace while the editor is focused, so an
  in-flight commit doesn't clobber the user's uncommitted keystrokes (ExternalSync kept for unfocused).
- Verified ensureMotionPathPluginLoaded already guards __hfMotionPathPluginLoading (no double-append).

* fix(core): align __clipTree and __clipManifest ids via stableClipId

Timeline inline expansion was dead for nested children inside index.html:
the tree keyed id-less elements by a synthetic __clip-N while the manifest
keyed them null, so parent<->child never joined. Both now resolve identity
through stableClipId (id || data-hf-id), which every generated element has.

* fix(core): strip baked runtime + tag comp root in preview assembly

Comps that ship a baked inline runtime were double-loaded (preview injects
its own) and the baked copy failed to parse inline (Unexpected token '<').
Strip it in buildSubCompositionHtml + the disk-fallback preview path. Also
tag the comp root with data-composition-file so the studio resolves a comp's
top-level elements to the right source file instead of defaulting to
index.html (which made the GSAP panel parse the wrong, multi-timeline file).

* feat(studio): set motion-path destination from a toolbar toggle

Replaces the double-click-on-canvas UX (which painted text over the preview)
with a 'Set motion destination' toggle next to Snap/Grid, shown only when the
selected element can take a path. While armed, one canvas press places the
destination. Also removes the dead TimelinePropertyRows component.

* fix(studio): center timeline keyframe diamonds on their percentage

Dropped clampDiamondLeft, which forced boundary keyframes fully inside the
clip so a 0% diamond sat half a diamond right of the 0% point. Each diamond's
midpoint now sits exactly on its % (the clip is overflow-visible).

* fix(studio): resize static elements via tl.set, not a single-stop keyframes tween

Resizing an element with no size animation wrote keyframes:{ <playhead%>:
{width,height} } — one mid-point stop GSAP can't interpolate, so it rendered
NaN/0 dimensions at every other frame and the element vanished (worst off 0%).
Added commitStaticGsapSize (mirrors commitStaticGsapPosition): a static resize
now writes tl.set({width,height}), held at all frames; re-resizing updates it
in place.

* fix(studio): negative-cache failed media probes

Only successful probes were cached, so CORS/404 cross-origin media was
re-probed every rAF-driven timeline re-derive, flooding the console. Remember
failed URLs and skip them.

* fix(studio): type window.setTimeout handle as number

ReturnType<typeof window.setTimeout> infers NodeJS.Timeout when @types/node is
present and clashes with the DOM number the call returns. Type it number.

* fix(studio): drag/resize disappearance, stale-ID duplicates, soft-reload clearProps

- Fix soft-reload clearProps destroying element inline styles — save cssText,
  clear, restore, strip only transform
- Fix resize no-op on re-resize: delete+add instead of two update-property
- Route set tweens through static resize path (convertToKeyframes skips sets)
- Re-fetch animation ID before drag commit to prevent stale-ID duplicates
- Guard editDebugLog for Node test environments
- Fix NLELayout setState-during-render (move reset to useEffect)
- Stop SnapToolbar pointer events propagating to canvas deselect handler
- Enable click-to-add waypoints on cubic motion paths
- Add whole-path drag offset (Alt+drag shifts all keyframes together)
- Add Canvas shortcuts section to ShortcutsPanel
- Extract useMotionPathData + commitGsapPositionFromDrag (filesize compliance)
- Delete dead code (getElementDepth, isElementVisibleInPreview, unused exports)
