feat(studio,core): a volume and a living meter on the group row
B7: the group bus strip — droppable, and deliberately minimal per the casual-user design constraints (groups doc §5): a volume slider, a level bar that moves with the sound, and the words "Too loud" when it clips. No dB numbers, no peak-hold readout, no routing row. Transport (core): groupInput() now routes each group through input -> [FX chain or dry passthrough] -> output -> master, with one AnalyserNode per group tapped off `output` (post-FX, so the meter reads what the bus actually outputs) — fftSize 256, level not spectrum. groupLevel(groupId) returns RMS-ish level 0..1 + a clipped flag off a reused per-group buffer (no per-frame allocation), or null when the group is idle/unknown. The runtime posts group-levels messages only while playing, piggybacking the existing message channel rather than adding a new poll loop. Studio: groupLevels.ts is a plain pub-sub store (mirrors liveTime.ts's shape) fed by useTimelinePlayer's message handler via parseGroupLevelsMessage; useGroupLevel throttles re-renders to ~33ms. TimelineGroupBusStrip renders in the group row's own `∿` lane area (STRIP_H, already sized in B2's row-height pipeline) — drag writes live via onSetAudioGroupAttributeLive, release commits one undo entry via onSetAudioGroupAttributeQuiet (packages/studio/src/hooks/ timelineAudioGroupVolume.ts, extracted from timelineTrackVisibility.ts to stay under the 600-line cap; mirrors FxParamRow's live/commit split). "Too loud" holds for ~2s after the last clipped block, tracked in the component, not the transport. volumeByGroup mirrors labelByGroup in useTimelineTrackDerivations.ts so the strip's slider round-trips the group's own data-volume. Fixed two pre-existing group-routing tests in webAudioTransport.test.ts that hardcoded gain-node creation order/count — B7 inserts an extra `output` gain node between the group's input and master (for the meter to tap), which shifted node indices the tests asserted on directly.

feat(studio,lint): carve targets voiceover groups — always, when plural
Plural voiceover carve now targets a group instead of naming each clip: `resolveCarveSourceIds` (core `audioGroups.ts`) expands a group id to its current members at analysis time, so a clip added to the group later is covered without touching `sources`. The picker (`useFxCarve.ts`) offers a grouped voice as one option instead of one row per member, tests overlap as a union of member spans (a group overlaps the bed if ANY member does), and prefers a qualifying group over its individual members in `autoSourceIds`. Picking two or more ungrouped voice clips in the carve flow now mints a group behind them (`mintGroupId`, de-duped against every id in the document) and writes `data-audio-group` on each picked clip atomically, one undo entry — `createAudioGroupAndAssignMembers` in `timelineTrackVisibility.ts` copies `setElementsHidden`'s multi-target write shape. The DSP is untouched: `mixCarveSources` already sums multiple sources correctly (verified in the design doc's own investigation) — this only fixes the picker. New lint rule `audio_carve_ungrouped_sources` (`packages/lint/src/rules/ media.ts`, alongside `audio_volume_double_automation`) warns when a `data-fx-carve`'s `sources` names two or more plain clip ids instead of a group — the shape that silently rots when a clip is added. `/hyperframes- audio` states the same rule as an invariant, not a tip, with the grouped- narration HTML example from the design doc. The group-matching and auto-group logic (`withAutoGroupedSources`, `collectCarveCandidates`) is split into `useFxCarveGrouping.ts` — `useFxCarve.ts` was pushing past the 600-line cap. `resolveNextCarveSettings` is deliberately NOT an `async function`: wrapping it in one would force a microtask on every call, including the synchronous branch — the exact bug `withAutoGroupedSources`'s own sync-when-possible contract exists to avoid, and one caught via `propertyPanelAudioFxGroup.test.tsx` (10 failures) before fixing it back to a plain function the caller conditionally awaits. Also extracted `useEffectiveTimelineDuration` out of `App.tsx` and `useRemoveBackground` out of `StudioRightPanel.tsx` (both pushed past 600 lines from an added prop wire), and decomposed `useFxCarve.ts`'s picker IIFE to clear fallow's complexity gate.

fix(core,studio): silence hidden audio in preview, and call it mute
Preview scheduled every audio[data-start] regardless of data-hidden, so a hidden audio track was silent in the export but audible in preview — render was already correct, this was a preview-only parity bug. Web Audio scheduling now skips (and re-syncs on toggle) any audio clip under a data-hidden ancestor; the HTMLMedia per-tick volume path folds the same check into effectiveVolume without touching el.muted (transport-owned). Ships unflagged since it's a bugfix restoring parity. Also relabels the eye as Mute/Muted on audio-only track rows (icon, strikethrough label, undo-history copy), gated behind the new audio-track-mute canary — the relabel is a copy/UX change, kept separate from the behavior fix above.

fix(studio): scope lane ids per timeline and stop inventing a track row
Two latent defects in the announcement path this branch adds. - lanesId was keyed by render row alone, so a second TimelineLanes on the page (a mini-timeline beside the main one) would mint the same timeline-lanes-track-0 and every caret's aria-controls would resolve to whichever instance mounted first. The prefix now comes from useId, with the colons stripped so the id stays a legal CSS selector. - trackDisplayNumber returned trackOrder.length + 1 for a key it could not find, which is indistinguishable from a real row: the label announced a row the user can see is wrong and nothing upstream could tell it had guessed. It returns null now, and trackDisplaySuffix drops the number from the label rather than inventing one. |

fix(studio): label undo history with the track display row
The timeline track key is a fractional z-order sort key: an expanded sub-composition child gets `host.track + n / (siblings + 2)`. The undo history entry for the eye toggle interpolated that key directly, so hiding an expanded child recorded "Hide track 0.16666666666666666". Give the key-to-display-row conversion a single owner (timelineTrackDisplay.ts) and route both the track header labels and the history label through it, so the two cannot drift apart again. The raw key still routes the callbacks and lookups that need it. Adds a regression test that toggles a track keyed 1 / 6; a test on track 0 formats cleanly and proves nothing. |

fix(studio): atomic timing pin, expanded-list Hide All, repeated-host matching, pointercancel revert
Fixes real bugs from two independent re-reviews (#2225 @ 65954c3804, #2416 @ beaf4ffbf6): - FlatTimingRow's pinRange committed a pinned start+duration range through TWO sequential onSetAttribute calls. Each resolves domEditSelection fresh from current hook state, so a selection change between the two awaits could misdirect the second write at the newly-selected element instead of the one being edited, and a failure of just the second call left the pair half-applied (inconsistent inferred/explicit state). Added commitDataAttributes/handleDomAttributesCommit (mirroring onCommitAnimatedProperties's same-shaped fix for GSAP property batches): one PatchOperation[] persist call against an explicit, caller-supplied selection — not the "current" one — threaded through as the new optional onSetAttributes prop. pinRange uses it when provided, falls back to the old sequential behavior otherwise. - Hide All silently dropped nested sub-composition children: a selection inside a sub-comp with no timeline-store entry of its own resolves to a virtual `sourceFile#domId` key (the fallback branch exists so the expansion hook can later resolve it via clipParentMap), but toggleTimelineElementHidden only searched the RAW store list, which never contains that key. useTimelineElementVisibilityEditing now resolves against useExpandedTimelineElements() instead, matching the track-based toggle's existing approach — the expanded list synthesizes a real, patchable TimelineElement (matching key/domId/sourceFile) for each visible child whenever its host is currently expanded. - Two composition hosts importing the same sub-composition collapsed to the first one: findMatchingTimelineElementId ORed domId/selector/ compositionSrc matches with equal priority in a single per-element scan, so `.find()` could stop at an EARLIER, unrelated host that merely shared the compositionSrc, before the scan ever reached the correct domId/ selector match further down the list. Restructured to try domId, then selector, across the WHOLE list first; compositionSrc-only matching is now a true last resort for when neither identifies a specific element. - FlatSlider's native pointercancel handler (a platform-level gesture abort — scroll/touch takeover, pen leaving range) manually duplicated the pointer-capture release logic instead of calling cancelDrag, so it never reverted to the pre-drag value — leaving whatever intermediate position the pointer last reached committed, unlike the Escape/right-click paths added in the previous round. Now calls cancelDrag directly. - useColorGradingController's flushPendingPersist read identityKeyRef.current fresh at flush time rather than a value snapshotted when the edit was scheduled. Defensive fix: added pendingPersistIdentityRef, set alongside pendingPersistValueRef in commitColorGrading, read by flushPendingPersist instead of the live ref — closes the gap regardless of how unlikely the actual race is given the identity-cleanup effect's existing eager-flush behavior. Two prior findings re-verified as already fixed further up this same Graphite stack (not re-fixed here, per established stack-order handling): metadata-cache negative-caching (267cdfce1) and cross-file selectionIdentityKey (6f40e03a1), both landing after #2225's reviewed head. StudioRightPanel.tsx crossed the 600-line file-size gate after wiring the new onSetAttributes prop through; extracted the inspector split-pane resize handlers (previously inlined) into their own useInspectorSplitResize hook. New regression tests: repeated-composition-host resolution, atomic vs. fallback pinRange commit paths, pointercancel revert. Full studio suite still at the known pre-existing 55-failure baseline, zero new regressions. Typecheck/oxlint/oxfmt clean. |

feat(studio): mirror canvas z-order actions into timeline lanes (track order = default paint order) (#2380)
* feat(studio): mirror canvas z-order actions into timeline lanes, badge z overrides
Track order = default paint order; authored z = advanced override.
- timelineZMirror.ts: pure resolver mapping a successful z-menu action to a
timeline lane move — closest track in the action's direction that is free
over the clip's whole span, else a new lane adjacent to the crossed
neighbor; temporal-overlap scope (default pending product sign-off, see
module doc); visual zone only; same-file reference scoping; persistTrack
via the shared authored-space rules. null for non-clips (menu stays
z-only) and at-extreme/no-overlap cases.
- useCanvasZOrderTimelineMirror.ts: after the z commit resolves, the mirror
persists the lane move through the same machinery as a timeline lane drag
(optimistic store update, authoredTrack refresh, rollback); inserts reuse
commitTrackInsert's renumber via a shared buildTrackInsertEdits core. Both
writes share one coalesce key (zReorderCoalesceKey) and fold into ONE undo
entry (test proves it over the real history reducer). The mirror never
triggers the lane->z stacking sync, so it cannot fight the z values the
action just set.
- timelineZOverride.ts + TimelineClip badge: clips whose paint order
contradicts lane order among temporally-overlapping same-context visual
neighbors (laneIsAbove XOR paintsAbove, the stacking-sync predicates) show
a 'z' badge — authored z overrides are surfaced instead of silently
disagreeing with the timeline.
- Timeline.tsx track derivations extracted to useTimelineTrackDerivations
(600-line cap).
* fix(studio): fold mirrored z-order gestures into one undo entry across slow persists
Live verification caught the z write and the mirrored lane write splitting
into two undo entries: the mirror runs after the z persist's server round
trip, which exceeds editHistory's default 300ms coalesce window under real
latency (the unit test's deterministic clock sat inside it).
zReorderCoalesceKey now mints a per-gesture-unique key (monotonic seq, the
laneChangeGestureSeq precedent) and both records carry coalesceMs Infinity —
distinct gestures can never merge, and one gesture always folds regardless
of write latency. coalesceMs threaded through the persist chain alongside
coalesceKey. Also hardens the existing lane-drag move->z fold, which had the
same latent split. Fold test now simulates a 400ms gap (failed before the
fix, passes after); a two-separate-gestures test asserts two entries.
* feat(studio): flashless lane mirror, z-order menu icons, close-gap track menu
- Track-only batch moves (the z-mirror's lane hop and the insert renumber)
skip the GSAP fallback round-trip and the preview reload entirely — the
renderer never reads data-track-index, and the live DOM patch + optimistic
store update cover the UI. Mixed batches keep current behavior. Kills the
canvas blink on mirrored Bring/Send actions (live-verified: an
iframe-scoped marker survives the whole gesture).
- The four z-order menu items get 16px stroke icons (single layer diamond +
directional arrow for Forward/Backward; pierced two-layer stack for
Front/Back); labels unchanged — they are the industry-standard names.
- New track context menu on empty lane space: 'Close gap' (shifts the next
clip and every clip after it on that lane left by the clicked gap's width;
leading gaps count, so a single clip with empty space before it compacts
to 0) and 'Close all gaps' (whole lane contiguous from 0). Pure gap math
in timelineGaps.ts; persists through the drag path's atomic batch move
(one undo per action); refuses when a clip that must shift is locked;
items disable when there is nothing to close.
* fix(studio): rebind-only preview sync for unmutated timing edits, classical z-menu order
Timing edits that rewrote NO GSAP positions (gap closes and moves of
selector-addressed caption clips, zero-delta batches, comps without a
rewritable script) full-reloaded the preview — and the rerun-current-scripts
attempt was wrong for real compositions: re-executing init-style scripts
(three.js scenes, caption engines) is exactly the unsafe case, verified live
by doubled init warnings and a fallback reload anyway.
The correct observation: when mutated === false the existing __timelines are
still valid — only the runtime's clip visibility windows are stale, and the
live DOM timing attributes were already patched. So the no-mutation path now
runs applySoftReloadFinalization only (seek + __hfForceTimelineRebind +
manual-edits reapply), extracted from the soft-reload machinery — zero
script execution. This also un-blinks comps with no GSAP script at all,
which previously always remounted. Rewritten-script soft reloads,
cannot-soft-reload, otherFileChanged, and mutation failures keep their
existing behavior. gsapSoftReload's undo/redo restore section moved verbatim
to gsapUndoRestore.ts for the 600-line cap.
Also: z-order menu items reordered to the classical arrangement (Bring to
Front, Bring Forward, Send Backward, Send to Back).
Live-verified on a three.js-heavy composition: Close-all-gaps shifted 4
caption clips with correct cumulative amounts, the preview iframe was never
remounted (marker survived), and one undo reverted everything.
* fix(studio): bound forward/backward mirror to a one-element step
User-specified semantic: Bring Forward / Send Backward move the clip past
EXACTLY ONE element. The mirror's lane target is now bounded by the next
temporally-overlapping element beyond the crossed neighbor: a free lane
strictly between the two is taken (closest to the neighbor), and when they
are back-to-back a new track is inserted immediately beyond the crossed
element — never past the second one. Previously the resolver took the
closest free lane anywhere beyond the neighbor, which could carry the track
past a second element while the z action only stepped past one — a
track/paint contradiction our own zOverride badge would flag. Front/back
keep whole-set semantics (past everything; back stays above the audio
zone). End-to-end test pins the 3-stacked case through commitZMirrorLaneMove
to the persisted renumbered tracks.
* feat(studio): permanent gap-menu rows with hover and click-select gap highlights
- TrackGapContextMenu always renders both rows; an inapplicable action dims
with a tooltip ("No gap here" / lock reason / "No gaps on this track")
instead of vanishing into a one-item menu. Width badge only when a gap
exists under the pointer.
- Hovering an ACTIONABLE row highlights the strip(s) it would close in the
timeline: the single gap for Close gap, every current gap (leading included)
for Close all gaps. New resolveAllGapIntervals in timelineGaps.ts reports
present-state intervals (epsilon-tolerant, overlap-safe), distinct from
resolveAllTrackGaps' post-compaction starts.
- Click-selecting a single clip paints a quieter tint over its lane's gaps
(suppressed for marquee multi-selection and during drags; the gap-menu hover
wins on its own lane). Derivation lives in useTimelineGapHighlights with the
pure buildTimelineGapStrips exported and unit-tested.
- Strips render in TimelineCanvas with the drop-placeholder geometry (row top
+ clip inset), dashed accent for hover, faint tint for selection.
- Timeline.tsx stayed under the 600-line cap by extracting the scroll-viewport
plumbing (ResizeObserver width + shortcut-hint sync) into
useTimelineScrollViewport, behavior unchanged.
* feat(studio): stronger capcut-style timeline zoom steps
One button press / pinch gesture now moves the zoom meaningfully: step
factors 1.25x/0.8x -> 1.5x/(2/3) (kept reciprocal so in+out round-trips) and
pinch sensitivity 0.0035 -> 0.007. Addresses "zooming several times to get
anywhere" feedback; cursor anchoring unchanged.
* feat(studio): three-way z sync — layers drags mirror timeline lanes, panel tracks live z edits
Completes the layers/canvas/timeline sync triangle: the Layers panel was the
one surface whose reorders never reached the timeline, and the one that went
stale when the other two wrote z flashlessly.
- Layers drag -> minimal z + equal-jump lane mirror. handleReorder now uses
the canvas menu's realization core via resolveZOrderReposition (one
between-z write when a strict gap exists, band-safe scoped renumber
otherwise) instead of computeReorderZValues' all-sibling stamp — that
helper is deleted, completing the #2347 unification follow-up. The drop
then mirrors into a timeline lane move through the same machinery as the
canvas menu (new resolveRepositionLaneMove: the clip lands on a free lane
strictly between its NEW paint neighbors' lanes — nearest clip siblings in
the desired render order, decorations skipped — else a track insert at
that boundary; audio zone never crossed). Both writes share one
per-gesture zReorderCoalesceKey with an unbounded fold window, so a drag
is exactly ONE undo entry; useCanvasZOrderTimelineMirror's plumbing is
factored into useMirrorLaneMoveCommit and reused by the new
useLayerReorderTimelineMirror. A same-slot drop is a hard no-op (new
order-equality guard in resolveZOrderReposition).
- Panel staleness fix: flashless z commits (skipReload) reload nothing and
bump no refreshKey, so the panel's z-sorted order went stale while paused.
handleDomZIndexReorderCommit now bumps a store zEditVersion on apply AND
rollback; the panel re-collects on it. Verified live: the panel re-sorts
the instant a drag commits and again on undo.
- Layer click reveal (useLayerRevealOverride): clicking a layer that stays
hidden at the current frame (animation-parked opacity, non-clip
display/visibility hides, hidden ancestors) temporarily forces the chain
visible with live inline styles — exact priors restored on deselect, on
another reveal, on play, and on unmount; never persisted (file diff == 0
verified live). Clips keep the existing seek-into-window behavior; the
override applies on a short defer so a seek-revealed clip needs none.
- layerOrdering's unused hasExplicitZIndex probe (zero callers) removed.
Live-verified on a bed copy: a 2-position layers drag wrote exactly one
element (z 6->23 + data-track-index 15->2), the timeline lane moved without
a reload, and a single Cmd+Z restored the file byte-identically.
* feat(studio): full-track selection highlight, borderless gap hover strips
- Click-selecting a clip now lights the WHOLE lane minus its clips — leading
gap, inter-clip gaps, and the open space after the last clip to the rendered
end (new resolveLaneEmptyIntervals; displayDuration threaded into the strip
derivation). Still click-only: any drag/resize suppresses the strips, and a
marquee multi-select never shows them.
- The gap-menu hover strips drop the dashed border (user feedback) — fill only,
nudged to 0.18 alpha to keep the same visual weight.
* feat(studio): selected layer paints on top via a reader-transparent z lift
Clicking a layer in the Layers tab now shows the element as if it were at the
very top of the stack while selected — whatever its authored z or panel
position — extending the reveal override (which already forced hidden chains
visible) with a temporary inline z lift:
- liftElementToTop parks the TRUE effective z in data-hf-reveal-prior-z and
writes a far-top inline z; a static element gets a layout-preserving
position:relative with its prior parked in data-hf-reveal-prior-pos. Only
the RENDERER sees the lift: all three studio z readers
(readTimelineElementZIndex, getElementZIndex, readEffectiveZIndex) return
the parked prior while the attribute is present, so the canvas z-menu, the
zOverride badge, the lane mirror, the stacking sync, and the panel sort
keep reasoning on the element's real z.
- Strictly ephemeral: exact priors restored on deselect / another reveal /
play / unmount, each property only while it still holds the value the
override wrote (a later real edit is never clobbered). File diff == 0
verified live across a full lift/restore cycle.
- A z-reorder commit CONSUMES an active lift (handleDomZIndexReorderCommit
reads the parked position for its persist-position:relative static check,
then drops the attributes) — the committed z becomes the truth and the
later restore is a guarded no-op.
* fix(studio): flashless undo/redo — three full-reload causes in the soft-restore path
Cmd+Z blinked the canvas on essentially every undo. Three independent causes
in applyUndoRestoreToPreview, each sufficient on its own:
1. Master-view path gate: activeCompPath is NULL at the master view, so the
'paths[0] === activeCompPath' eligibility check could never match the
index.html restore and every default-view undo full-reloaded at the first
gate. Normalized to the codebase-wide 'activeCompPath ?? "index.html"'.
2. Nested identity innerHTML check: the diff compared each identified
element's innerHTML, but the composition root wraps every clip — any child
change re-detected at the root rejected the restore. Change detection now
compares only each element's OWN attribute surface; structure/text
integrity is still guaranteed by the normalize-residual whole-doc pass
(text nodes, added/removed elements, and un-identified attrs all remain
after normalization and force the full reload).
3. id-only identity: elements addressed by data-hf-id / selector (no DOM id)
fell outside the diff entirely. Identity is now id OR data-hf-id, with the
live sync resolving either.
Also stop re-running an UNCHANGED GSAP script: attribute-only restores (z,
lane, timing, style — the overwhelmingly common undo) now use the rebind-only
finalization (seek + __hfForceTimelineRebind + manual reapply, zero script
execution — the same path as flashless timing edits), instead of tearing down
and rebuilding live timelines or full-reloading when the script can't be
scoped. A restore whose script text genuinely changed still re-runs it via
applySoftReload, and structural restores (split/delete) still full-reload.
Live-verified on the bed (iframe marker): gap-close undo AND redo both keep
the iframe mounted, live DOM lands on the restored values, disk restored
byte-identically.
* feat(studio): left breathing pad before t=0, double zoom sensitivity again
TRACKS_LEFT_PAD (48px) — the horizontal sibling of TRACKS_TOP_PAD: empty lane
surface between the sticky gutter and the ruler's 00:00 / the first clips,
scrolling WITH the content.
- The lanes and the ruler realize it as a plain flow spacer between the
sticky gutter cell and the time-mapped content div, so every
content-relative computation (clip left = t*pps, beat lines, lane-menu
time, clip drag deltas) is untouched by construction.
- Canvas-space overlays shift by the pad: playhead (getTimelinePlayheadLeft),
gap strips, drop placeholder, snap guide, range highlight, marquee clip
rects, beat SVG; the insert line spans the pad.
- Every pointer->time inverse subtracts it symmetrically: seekFromX, razor,
range/marquee anchors, asset drops, and the zoom-anchor gutter basis; fit
pps and the display width account for the consumed viewport width.
- Live-verified: t=0 clip edge, the 00:00 tick, and the playhead line center
all sit at GUTTER + TRACKS_LEFT_PAD, and a ruler click lands the playhead
center exactly under the pointer.
Also doubles the timeline zoom sensitivity again (user feedback after
feel-testing the first bump): button steps 1.5x/(2/3) -> 2x/0.5, pinch
0.007 -> 0.014.
* fix(studio): left pad renders as true empty space, not lane surface
The pad before t=0 inherited each row's background and bottom border from the
row wrapper, so it read as track lanes. Lane visuals now live on the cells:
the sticky gutter keeps its own separator (header column stays delineated),
the time-mapped content div carries the row background + separator, and the
pad spacer stays transparent — bare shell background, no lines. The
new-track insertion line also starts at the pad's end instead of crossing it.
* fix(studio): no vertical line in the ruler band before 00:00
The ruler corner's right border drew the header-boundary line through the
ruler strip, so the band didn't read as starting at 00:00. Dropped it — the
boundary line belongs to the track rows below; the ruler stays completely
clean from the panel edge to the first tick, matching the empty left pad.
* refactor(studio): remove the timeline z-override badge
User decision: the "z" chip on clips never earned its place — dropped
entirely (timelineZOverride.ts + test deleted, TimelineClip badge rendering
and the zOverrideKeys derivation/threading removed). This also eliminates the
review's D2 finding at the root: the badge's cross-document comparison
(stackingContextId ?? null collides across source files in the expanded view)
produced false positives, and there is no longer a detector to mis-fire.
overlapsInTime/paintsAbove lose their export (the badge was their only
external consumer); the paint-order predicate itself is unchanged.
* fix(studio): collision-free expanded child lanes and host-window gap floors
Review findings D1 (blocker) and 4.
- D1: buildChildElements assigned expanded children synthetic display rows as
`host.track + index` — integers that can EQUAL a real clip's lane in another
file (host on 0 with two children puts child #2 on 1). Lane grouping merges
purely by track number, so the collision fused clips from different source
files into one display lane, and lane-scoped actions (the gap menu) then
batch-persisted a foreign file's clip. Children now take FRACTIONS strictly
between the host's lane and the next integer — structurally unable to
collide with any normalized lane, while still rendering as ordered rows
under the host. Regression test pins the reviewer's exact two-file scenario.
- Finding 4: gap math compacted toward absolute 0, but an expanded child's
display time is host-anchored — close/compact could drag it before its host
window and persist a wrong (even negative) local time. All gap functions
now take a lane FLOOR (laneGapFloor: 0 for ordinary lanes, the children's
expandedParentStart for child lanes — single-origin per lane post-D1),
threaded through the menu model, hover highlights, selected-lane strips,
and both commits. Close-gap shifts clamp at the gap's own left edge.
* fix(studio): scope mirror references, insert writes, and crossed-neighbor identity
Review findings 1, 2, and 3.
- Finding 1: buildTrackInsertEdits normalized the FULL display set and
persisted every shifted clip — writing host-lane numbers into OTHER
composition files when expanded children were showing. The renumber write
set is now the edited element's own source file (the sanctioned multi-write
converges one FILE to lane space, never neighbors' files); foreign clips
keep their authored tracks and re-derive display lanes. The locked-clip
refusal scopes the same way. Expanded-origin elements refuse the insert
outright (a new lane is a host-space renumber, meaningless in the child's
file), and the mirrors restrict an expanded child's lane candidates to its
own siblings' lanes — a sub-comp child still mirrors WITHIN its sub-comp
(persisting the sibling's authored track) but can never land on a host lane
with no same-file occupant. authoredTrackForLane's offset fallback rounds:
fractional synthetic rows must never leak fractions into data-track-index.
- Finding 2: the mirror comparison sets required only sameSourceFile, but a
file can contain several CSS stacking contexts and leaf z is only
comparable within one. Both resolvers now scope by samePaintScope — same
source file AND same stackingContextId (the file check also stops null root
contexts of different files from comparing equal in the expanded view).
- Finding 3: the crossed-neighbor key was derived without selectorIndex, so
duplicate class selectors (.sub) resolved to occurrence 0 — a different
clip. The key now carries getSelectorIndex, matching how z-reorder entries
derive theirs.
* fix(studio): z-to-lane gestures are one serialized transaction gated on durable persists
Review findings 5 and 7.
- Finding 5: commitDomEditPatchBatches resolved successfully even when the
server matched NO patch target — the z write never reached disk (the
preview reloads to reconverge) yet the lane mirror still ran, desyncing
track order from what actually paints. The commit now resolves a durability
report ({allMatched, changed}; the save queue and commit types are generic
over the result), and the mirror phase is skipped on allMatched === false.
- Finding 7: the z persist rides the DOM-edit save queue while the lane move
rides the timeline/SDK path — two queues, so a second rapid gesture's z
write could land BETWEEN the first gesture's z and lane phases. Every
z-to-lane gesture (canvas z-order menu AND Layers-panel drag) now runs
through runZLaneGesture: a single module-level tail that serializes the
COMPLETE two-phase transaction, with unit tests for ordering, the
durability gate, and queue resilience to failed gestures. The timeline
lane-drag's inverse (move-then-z-sync) shares its phases' await ordering
already; cross-gesture serialization for that path is noted as follow-up.
- LayersPanel's pure sort helpers moved to layersPanelSort.ts (600-line cap).
* fix(studio): multi-clip GSAP batch mutations roll back on late failure
Review finding 6. finishGroupTimingGsapFallback mutates files sequentially
per clip; a late per-clip failure left the earlier rewrites on disk with no
aggregate history entry — unreachable by undo. foldGsapMutationIntoHistory
already snapshots every touched path before mutating; on a mutation failure
it now restores each path whose disk content changed (all-or-nothing batch),
reports restore errors without masking the original failure, and rethrows.
Regression test drives a two-clip batch whose second rewrite fails and
asserts the first clip's write is restored byte-identically.
* fix(studio): scope mirror inserts to their lane zone
* fix(studio): unify source-scoped clip identity
* fix(studio): isolate track insert topology
* fix(studio): harden timeline paint synchronization

feat(studio): timeline revamp with active-clip highlighting and hide controls (#2017)
Timeline UI - Highlight clips visible at the playhead in the primary color; others share one neutral color - Minimalist rounded clips, single-color track rows, no gutter icons or superscript labels - Per-track eye toggle and a per-element hide button in the design panel - Ruler zoom fixes: sub-second tick intervals and correct label formatting at high zoom - Sticky gutter so track controls stay visible while scrolling WYSIWYG visibility (data-hidden) - Runtime honors data-hidden (display:none), so hiding affects the render, not just the preview - HTML stays the source of truth; hide state persists and round-trips on reload Split several studio files to stay under the 600-line cap; pure relocations, no behavior change. |
