* 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

Closes gaps surfaced by pacific#30298 (hyperframes layer panel), where consumer
code had to hand-roll fixes for things the SDK/core already solve or nearly solve:
- getRootElements(): getElements() flattens the tree, so every descendant also
appears as its own top-level entry. buildRoots() already computes true roots
internally; this exposes it directly instead of making consumers re-derive
roots by filtering out descendant ids.
- Export isNewHostBoundary + bareId from @hyperframes/sdk: both already existed
internally (engine/model.ts) but weren't exported, so consumers were
duplicating sub-composition-boundary detection and scoped-id-to-DOM-leaf
conversion by hand.
- Export stripEmbeddedRuntimeScripts + RUNTIME_BOOTSTRAP_ATTR from
@hyperframes/core, and wire serialize({ stripRuntime: true }) on the SDK
session: a proper tokenizing implementation already existed in
compiler/htmlDocument.ts (handles more runtime-script marker variants than a
naive regex), just never exported. The SDK itself imports these via narrow
subpaths (./runtime/start-expression, ./compiler/html-document) rather than
the wide ./compiler barrel, matching the SDK's existing import convention and
avoiding pulling Node-only compiler code (fs/path) into browser bundles.
- Fix getElementTimings(): data-start can be a relative-reference expression
("intro", "intro + 2" — see parseStartExpression's grammar), not just an
absolute number. The old code did a raw parseFloat() on it, which silently
resolved any reference expression to 0. Now resolves references recursively
against the target element's own resolved start + duration, Node-safe (no
live GSAP timeline needed for this case).
14 new tests (session.timings.test.ts, session.subcomp.test.ts). Full sdk
suite: 417/417 passing. Full workspace build (incl. studio) verified clean.
* fix(sdk): moveElement survives GSAP animation per-axis via runtime delta translate
A committed moveElement wrote data-x/data-y but nothing rendered them:
hosts shimmed CSS translate, which GSAP folds into the cached transform
at first parse and then discards on the animated axis at every seek —
dragging an animated element kept only the un-animated axis.
Spike-proven on GSAP 3.15: a translate set AFTER GSAP's first parse is
never read, folded, or cleared across seeks and composes natively with
the animated transform. So:
- moveElement captures the pre-edit baseline once (data-hf-edit-base-x/y)
- the runtime (new core runtime/positionEdits.ts, applied at timeline
bind — after GSAP parse) renders translate = (data-x − base), a pure
delta that composes with GSAP tweens, tl.set positions, and CSS alike
- applyDraft now drives the drag preview through the same translate
channel (the --hf-studio-dx/dy vars had no consumer outside authored
Studio bridges), and commitPreview mirrors the committed move onto
the live element so it holds without an srcdoc reload
Acceptance: packages/engine/scripts/test-runtime-position-edits-browser.ts
(real Chrome + GSAP + runtime IIFE, no Studio shell) — X-animated,
Y-animated, and static elements hold both edited axes across the full
seek range. New subpath export @hyperframes/core/runtime/position-edits.
Known limitation (documented): a tween created lazily at runtime that
first-parses a marked element after apply folds the edit.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix(sdk): harden position-edit rendering and the drag draft channel
Fixes six issues from adversarial review of the moveElement stack:
- Runtime: apply position edits at init as well as at timeline bind, so
committed moves render in compositions with no usable GSAP timeline
(CSS/WAAPI-animated or fully static) — previously the apply was
unreachable outside the boundDuration > 0 bind branch and the edit
silently vanished from reloads and renders.
- Runtime: guard bind-path re-apply against post-fold double-apply — if
the previously written translate was consumed externally (a lazily
created tween folding it into GSAP's cached transform), skip instead
of re-setting it on top ({force} escape hatch for editor commits).
- Adapter: stop writing the --hf-studio-dx/dy custom properties during
drags — compositions with the documented var-consuming drag-bridge
CSS moved by twice the pointer delta (var transform + new inline
translate). The inline translate is now the only draft channel;
deltas accumulate in adapter fields. Docs updated to match.
- Adapter: switching applyDraft to a new id reverts the abandoned
element's draft translate instead of leaving it displaced with no op.
- Adapter: cancelPreview restores the raw inline translate (removing it
when there was none), so a stylesheet-authored translate is never
promoted to a permanent inline style.
- Adapter: commitPreview reverts the draft and clears state when
dispatch throws, instead of leaving the element shifted by an
uncommitted draft.
Cleanups: reuse readCurrentTranslate from the core module (was a
verbatim copy), drop the dead __hfApplyPositionEdits window hook.
Browser acceptance test now also covers the GSAP-free composition path.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix(core): prime GSAP transform cache before position-edit apply; add fold-loss telemetry
Addresses PR #1875 review feedback (Rames, Miga):
- Prime the element's GSAP transform parse (gsap.getProperty) before the
first translate apply — positioned tl.set()s and tweens that first
RENDER after the apply now reuse the cache instead of folding the edit.
This closes the lazy-first-parse fold-loss for any page where GSAP is
loaded at apply time; the residual limitation is GSAP itself loading
after the apply. Proven by the extended browser acceptance test.
- Emit position_edit_fold_skipped analytics at the fold-guard skip site
so the residual degradation is observable instead of silent.
- Browser acceptance test: add a both-axis-animated element (the shape
that originated the per-axis loss) and a positioned tl.set() element,
asserted across the full seek range.
- Simplify the num() null guard (review nit).

## What
Foundations of the `@hyperframes/core/figma` module — the pure, transport-agnostic layer every later phase builds on:
- **`types.ts`** — `FigmaRef`, `FigmaProvenance`, `FigmaManifestRecord`, and the Motion model (`MotionDoc`/`MotionTrack`/`TimelineSpec`/`GsapTween`) shared across the stack.
- **`parseFigmaRef`** — normalizes any user input (full `/design|/file|/proto` URLs with `?node-id=1-2`, `fileKey:nodeId` shorthand, bare `fileKey`) into `{ fileKey, nodeId }`, including the URL-dash → API-colon node-id conversion.
- **`freeze.ts`** — `freezeBytes`/`freezeUrl`/`freezeLocalFile` with a 256 MB cap; every Figma asset is frozen to a local file before it can reach a composition (determinism: no render-time network).
- **`manifest.ts`** — the `.media/manifest.jsonl` ledger (same layout `media-use` writes, so a project has one shared media inventory without either skill depending on the other): append/read/find-by-node/next-id, with a pure type-guard (`isFigmaManifestRecord`) instead of `as`-casts.
- **`assetSnippet.ts`** — manifest record → composition `<img>` snippet with escaped attrs + `data-figma-id`.
- **publishConfig fix** — `./figma` added to `packages/core` `publishConfig.exports` (the packed-manifest CI gate requires every source export to have a dist mapping).
## Why
Design spec: `docs/superpowers/specs/2026-06-30-figma-asset-integration-design.md`. These functions are deliberately transport-agnostic — when the project reversed from MCP-first to a REST/MCP split (spec §2), nothing in this layer changed. That was the point.
## Tests
Unit tests per module (URL variants, freeze cap edges, manifest round-trip/malformed-line tolerance, snippet escaping). All colocated `*.test.ts`, vitest, no network.

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.
