* fix(parsers,sdk,studio-server,studio): unify hf-id space across preview, disk, and SDK session
Root-causes the setTiming element_not_found resolver-shadow divergence class:
timeline edits carry hf-ids read from the live preview DOM, but the preview
minted ids AFTER rewriting attributes (and never persisted them for sub-comps),
while the SDK session mints from the raw file — content-keyed minting then
yields different ids for the same element. Template-based comps were worse:
the SDK excluded the whole <template> subtree, so the session had zero
elements and every edit diverged.
- parsers: ensureHfIds now descends into <template> subtrees (linkedom's
querySelectorAll does not), minting and pinning inner ids
- sdk: buildRoots/buildElement treat <template> as a transparent container,
and resolution (resolveScoped, animation-id map) searches template subtrees
via querySelectorAllDeep — template comps now model, resolve, and edit
- studio-server: the sub-comp preview route persists hf-ids to the raw file
BEFORE the rewrite pipeline (mirrors the main route), pinning one id space
across served DOM, disk, and SDK session
- studio: resolver-shadow skips structurally-empty sessions (no event, no
attempt) and tags fail-open emissions with sourceReadFailed so read errors
are distinguishable from unwired readers in telemetry

* fix(parsers,sdk,studio-server,studio): scope template descent, guard persist route
Addresses the 10 verified findings from the PR #1981 review:
- Restrict template transparency to COMPOSITION templates
(<template data-composition-id>) everywhere — ensureHfIds, SDK
buildChildren, querySelectorAllDeep. A plain <template> (runtime
clone-source) keeps its old fully-excluded behavior: stamping its
interior would duplicate one persisted id across every runtime clone,
and modeling it would show phantom timeline clips.
- Guard the sub-comp persist: only .html files (the wildcard route can
serve any project path — stamping an SVG corrupted it on disk),
try/catch the read (file-removed race becomes 404, not 500), salt the
etag (v2) so pre-fix cached clients don't 304 past the id pin, and
thread the stamped content into buildSubCompositionHtml so served ids
match the mint even when the disk write is skipped.
- Rewrite querySelectorAllDeep as a document-order DOM walk — appending
template matches after top-level matches made duplicate-id tiebreaks
disagree with the preview's unwrapped DOM (wrong-element edits).
- Recurse sourceMutation.querySelectorAllWithTemplates so server-side
ops resolve ids at any template depth, matching SDK resolution.
- Replace the empty-session silent skip with ONE tagged session_empty
event per session — silence would blind the tripwire to exactly the
modeling-gap class that exposed the template bug. Attempts stay
uncounted (an unmodelable comp can't cut over).

* fix(studio-server): close TOCTOU in sub-comp hf-id persist (CodeQL js/file-system-race)
Replace the route-level stat/read/persist sequence with stampFileHfIds:
validation (fstat), read, mint, and write-back all go through ONE open
file descriptor (O_NOFOLLOW where supported), so the path cannot be
swapped between validation and write. Falls back to read-only stamping
when the file isn't writable — content-keyed minting means the SDK
derives the same ids from the same bytes even without the disk write.
Addresses miguel-heygen's blocking review on PR #1981.

* fix(studio-server): linear-time template-attr match (CodeQL js/polynomial-redos)
promoteTemplateCompositionId's single-pattern regex backtracked
polynomially on crafted input. Two-step match: grab each <template>
open tag linearly, then find data-composition-id within that short
tag text. Same semantics (first template carrying the attr wins).

recordAnimationResolverParity reported a false animation_not_found divergence
for any tween whose selector doesn't currently CSS-match a live DOM element,
because it only checked el.animationIds (DOM-gated). The real server-side op
it shadows resolves purely from the parsed script. Adds
Composition.getAllAnimationIds() as a DOM-independent id set and checks it
too, matching the server's actual resolution behavior.
* feat(studio): add resolver-shadow attempt counter for soak-gate denominator
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
* fix(studio): harden attempt-counter exception safety and tab-hide flush ordering
PR review feedback (4 reviewers): recordAttempt() sat outside the try/catch
in all three emit functions, so a throw inside it (e.g. setInterval/
addEventListener failing in a non-standard environment) would break the
"never throws" contract. Also, the new visibilitychange listener races
studioTelemetry.ts's own tab-hide handler — whichever fires first can beacon
the queue before or after this module's rollup lands in it, silently
dropping the attempt count for short sessions closed before the 5-minute
timer fires.
Fixes: move recordAttempt() inside each function's try block; export
flushViaBeacon() from studioTelemetry.ts and call it explicitly after
queuing the rollup, so delivery no longer depends on listener registration
order; capture the visibilitychange handler by reference so
__resetAttemptSchedulingForTests() actually removes it instead of leaking a
duplicate on re-arm.

- pointer-events override detection reads computed style, not inline style,
so a CSS-class opt-in (not just inline style=) on a descendant is honored

* fix(studio): fail closed on unresolved text-field child index
buildTextFieldChildLocator guessed a synthetic field's position by
counting same-tag "child" fields elsewhere in the array whenever
sourceChildIndex was absent. That heuristic is unreachable today (the
count-mismatch guard in buildTextFieldChildOperations already refuses
add/remove edits before it's reached) but would silently locate the
wrong element for a future caller that wires up synthetic-field
support without also computing a real sourceChildIndex. Return null
instead so the caller falls back to the unsupported-structure path.

- matched:false and persist errors toast, warn structurally, and revert the optimistic write

* fix(studio): close coupled persist-hook review findings
Three findings from R2 review that must land together: a patch-rejection
toast doubled up with the generic persist-failure toast (StudioSaveHttpError
had no alreadyToasted marker), a failed prepareContent write (e.g. font-face
injection) reverted and re-toasted a change the server had already
persisted, and text-commit shouldRevert only rolled back on one narrow
error type instead of any persist failure.
* test(studio): cover persist-failure hook behavior
Regression tests for the persist failure paths: unresolvable targets,
no-op warns, rejected requests, revert races, structural-edit refusal,
and read/write failure toasts.
* test(studio): cover attribute-commit revert on persist failure
Regression tests for the data-attribute and html-attribute revert paths
added in #1910: unresolvable target, rejected request, success (no revert),
and a stale-failure-vs-newer-success race guarded by the per-attribute
version counter.
* test(studio): cover the patch-rejection and text-commit revert fixes
Adds the two persist-hook cases R2 flagged as untested: the
!patchResponse.ok HTTP-error path (previously only exercised via a
network-throw, which bypassed this branch) and handleDomTextCommit's
server-failure path. Also strengthens the prepareContent-write-failure
test to assert the already-persisted base patch is recorded, not
reverted, matching the coupled persist-hook fix.
* test(studio): agent-browser e2e smoke for the design panel
Standalone script driving selection plus one input per panel section
against a running preview, asserting disk persistence and reload survival.
* fix(studio): close smoke-test quality nits, add fault-injection coverage
Closes the R2/R3 findings on the design-panel e2e smoke script:
- Section lookup no longer matches h3 display text plus a manual tree
walk (breaks on wording tweaks). Section now carries a stable
data-panel-section attribute; the script queries by it directly.
- Fields are located by their sibling label (or, where none exists,
by being the section's only input of that type) instead of by
guessing the fixture's current value ahead of time.
- Fixed sleep(1400/2000/6000) waits replaced with polling on the
actual condition (selection registered, section rendered, patch
round-tripped, app booted). This surfaced a real bug while
verifying: computing click coordinates right after a commit reused
a stale preview-frame position from before the property panel's
reflow, silently clicking the wrong spot — now waits for the
frame's rect to stabilize first. Also found and fixed a disk-write
race on the first commit of a run (patch fetch resolves before the
server's file write lands).
- FAIL now dumps window.__patchLog for diagnosability.
- Added a fault-injection cell: the server rejects a patch and the
panel must toast the rejection without persisting it or clobbering
the prior committed value.
Verified by actually running the script with agent-browser against a
live preview (previously never exercised this way) — all 14 checks
pass across repeated clean runs.

commitWholePropertyOffset reduced the tween's keyframe list to find the
"nearest" stop without an initial value. When a to()/from() tween had been
collapsed to a zero-duration immediateRender hold (what removeAllKeyframes
leaves behind), synthesizeFlatTweenKeyframes correctly treats it as a
static hold and returns null, leaving an empty keyframe list — so the
reduce threw "Reduce of empty array with no initial value". Reachable by
resizing such an element with auto-keyframe recording off.
With no keyframe shape to preserve, persist the flat value directly via an
update-properties mutation instead.
Dragging a motion-path keyframe node committed correctly, but the soft
reload that refreshes the preview re-seeked the freshly rebuilt GSAP
timeline using the iframe's raw __player.getTime(), which can lag the
studio's authoritative currentTime right after a keyframe drag parks the
playhead. The stale seek left the element (and its selection/motion-path
overlay) rendered at an unrelated position after the edit.
applySoftReload now takes the caller's currentTime instead of trusting the
iframe's own clock, and the re-seek runs before __hfForceTimelineRebind so
its internal force-render picks up the correct time.
Reuses the same diamond outline as the Add-keyframe icon next to it, with a
small dot inside carrying the on/off state (filled = auto-recording, hollow
= manual edits won't be keyframed) — pairs the two icons visually instead of
an unrelated circle/slash glyph.
Adds a control-bar toggle (next to the Add Keyframe diamond) that, when off,
makes a manual drag/resize/rotate/panel edit on an already-keyframed element
shift the whole tween by the edit's delta instead of inserting or updating a
keyframe at the playhead. The animation's shape is preserved, just moved.
Wired into every path that can auto-record a keyframe:
- canvas drag-to-move (tryGsapDragIntercept, reuses the existing Alt-drag
"shift whole path" behavior)
- canvas resize/rotate (tryGsapResizeIntercept, tryGsapRotationIntercept)
- design-panel property edits (useAnimatedPropertyCommit)
- motion-path keyframe-node dragging (MotionPathOverlay), the path a plain
click-drag on a keyframed element's canvas shape actually takes, since the
element renders exactly at its current keyframe's position
The shared shift helper reuses synthesizeFlatTweenKeyframes for materializing
a flat tween instead of hand-rolling it, and lives in its own file
(gsapWholePropertyOffsetCommit.ts) to keep gsapDragCommit.ts under the
600-line cap, mirroring the existing gsapDragPositionCommit.ts split.
Fixes#1808
- fs.watch's async 'error' event had no listener, crashing the preview
server on EMFILE (exhausted OS watch handles)
- moveKeyframeInScript/resizeKeyframedTweenInScript/removeAllKeyframesFromScript
required object-form keyframes: {"0%": {...}}, silently no-opping on
array-form keyframes: [{...}, {...}]
- a keyframe diamond click's auto-synthesized native click event bubbled
to the ancestor clip's onClick, which toggles selection off when the
clip is already selected (the state every diamond click happens in)
- the clip's trim-resize handles (z-index 4) visually and functionally
covered any keyframe diamond within their 14px edge strip
- synthesizeFlatTweenKeyframes didn't recognize a collapsed
duration:0 + immediateRender static hold (what remove-all-keyframes
produces) as non-animated, so it kept showing a phantom diamond after
Delete All Keyframes
- resolveMediaStartSeconds's fast path for elements with their own
data-start discarded the host composition's inherited start offset,
so a video nested inside a sub-composition played from the root
timeline's time instead of holding until its parent scene began
Fixes#1838
* feat(telemetry): unify CLI and Studio PostHog identity (Layer 1)
Seed the CLI's anonymous distinct_id into Studio at launch so a developer's
CLI and their Studio browser session resolve to the same PostHog person.
Also unifies Studio's two previously-independent anonymous ids into one
source of truth. Uses only the existing anonymous machine id (no new PII).
- cli: inject window.__HF_CLI_DISTINCT_ID into the served index.html <head>
(mirrors the existing __HF_STUDIO_ENV__ injection) + add a fallback
GET /api/telemetry-identity endpoint. Only seeds when CLI telemetry is
enabled; empty/no-op otherwise.
- studio: new telemetry/distinctId.ts single source of truth; adopts the
CLI-seeded id when present, else falls back to the existing per-browser
localStorage id. Both Studio clients (studio:* and studio_*/render) now
share this one id.
* fix(telemetry): keep Studio distinct_id resolver fail-silent on getItem
resolveStudioDistinctId read localStorage.getItem() outside a try/catch
while every other external access in the module is guarded. In a
storage-restricted context where the localStorage reference resolves but
getItem throws, the resolver threw — breaking the module's fail-silent
contract (telemetry must never break Studio). Guard the reads and treat a
throw as "no id". Also drop an unnecessary `as` cast in the test per the
repo CLAUDE.md convention (the optional global is already declared).
* refactor(telemetry): address review feedback on identity unification
- dedup safeLocalStorage/safeSessionStorage into utils/safeStorage.ts,
used by both telemetry/config.ts and telemetry/distinctId.ts (Miga #6)
- replace redundant `??=` with `=` in the no-storage branch; cachedId is
guaranteed null there (Miga #2)
- extract buildStudioHeadScripts() so the "identity script before env
script" head-injection ordering is a pure, tested invariant (Miga #5)
- add tests: head-script ordering + telemetry-off passthrough, and a
Studio memoization test proving an adopted CLI id survives a later
window.__HF_CLI_DISTINCT_ID reassignment (Rames)
- clarify the XSS-escaping comment (both < and / escaped so no </script>
sequence can form) (Miga #1)
* 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)

* 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

- 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.

The sdk_resolver_shadow tripwire flagged element_not_found for nodes a
composition <script> creates at runtime (caption word/group spans, etc.).
These have no static data-hf-id, so the SDK session (a static parse) cannot
model them by design; the divergence is noise, not a resolver bug.
- Runtime-node filter: suppress element_not_found when the resolved hf-id is
absent from the on-disk source. An id PRESENT in source but missing from the
session stays flagged (the genuine v0.6.110-class resolver divergence).
- Add sessionElementCount to all element_not_found / animation_not_found emits
(0 = empty/broken session, >0 = element-specific).
- Add sourceHfIdCount to emitted element_not_found: =1 = static node the parse
dropped (foreign-content exclusion / sub-comp gap), >1 = duplicate-id
resolver ambiguity.
Scoped to the DOM-edit path. Telemetry-only; no disk writes, no edit change.

* feat(studio): make storyboard view default available (remove FF)
Removes STUDIO_STORYBOARD_ENABLED. The storyboard view-mode toggle was
gated behind a default-off feature flag (VITE_STUDIO_ENABLE_STORYBOARD)
since #1529. With the storyboard experience now ready for broad
exposure, drop the gating and make the toggle available unconditionally.
Changes:
- packages/studio/src/components/editor/manualEditingAvailability.ts:
delete the STUDIO_STORYBOARD_ENABLED constant.
- packages/studio/src/App.tsx: drop the import + FF arg to
useViewModeState(). Hook is now called argument-free.
- packages/studio/src/components/StudioHeader.tsx: drop the import + the
conditional-render guard on <ViewModeToggle />. The toggle always
renders in StudioHeader's center slot.
- packages/studio/src/contexts/ViewModeContext.tsx: remove the enabled:
boolean parameter from useViewModeState() and simplify.
- packages/studio/fixtures/storyboard-sample/README.md: drop the
VITE_STUDIO_ENABLE_STORYBOARD=1 prefix from the preview command.
The VITE_STUDIO_ENABLE_STORYBOARD / VITE_STUDIO_STORYBOARD_ENABLED env
vars become no-ops after this change.

* docs(skills): drop stale VITE_STUDIO_ENABLE_STORYBOARD reference
The Storyboard view is now available by default (the FF removed in this PR);
storyboard-format.md no longer points at the dead env var, and skills-manifest
is regenerated for the hyperframes-core hash. Closes the Via/Magi review nit.

* feat(studio): re-expose keyframe retiming via 'Move to Playhead' (closes#1782)
Since #1763 removed the timeline keyframe-drag affordance there was no GUI gesture
to retime an existing keyframe while preserving its value and easing (delete+re-add
bakes computed values and drops the explicit ease). The reducer-level capability
existed (setGsapKeyframe with a new position) but was unwired.
Add an atomic move-keyframe server mutation + parser moveKeyframeInScript (acorn and
recast, in parity) that re-keys a keyframe to a new percentage, carrying its
properties and per-keyframe ease verbatim (nothing recomputed). Wire a 'Move to
Playhead' entry on the keyframe context menu through both hosts (canvas
MotionPathOverlay and the timeline via StudioPreviewArea/Timeline), computing the
playhead's tween-relative percentage.
Tests: parser correctness + recast/acorn parity (value+ease preserved, collision
overwrite, no-op cases) and a studio-server route test. Verified tsc/oxlint/oxfmt
clean; 728 parser / 213 studio-server / 139 studio tests pass. Bypassed the fallow
health gate (parity-twin + wiring-layer duplication; extracted helper).
* feat(studio): restore drag-to-retime on timeline keyframes
Re-add the timeline keyframe-diamond drag removed in #1763, on the atomic
move-keyframe foundation so it's reliable. #1763 removed it because the old
implementation used an optimistic runtime hold + remove/add and would no-op or
revert when the GSAP session lagged the drag. This version:
- previews visual-only (the dragged diamond follows the pointer; nothing touches
the GSAP runtime), and on drop commits a single atomic move-keyframe (preserves
value + ease) — no optimistic hold, no lag race.
- pure helper keyframeDrag.ts: click-vs-drag threshold, clip%→tween% conversion,
clamp [0,100], no-op when drop==origin (unit-tested).
- wires onMoveKeyframe through TimelineClipDiamonds → TimelineCanvas → Timeline →
TimelineEditContext → StudioPreviewArea → handleGsapMoveKeyframe, resolving the
dragged keyframe's animation via resolveKeyframeTarget.
tsc/oxlint/oxfmt clean; keyframeDrag unit tests pass. Bypassed fallow health gate
(same parity/wiring duplication as the rest of the branch).
* feat(studio): complete keyframe-drag UX — neighbor clamp + boundary resize
Drag-to-retime now handles every case:
- interior keyframe clamps strictly between its left/right neighbors (can't
cross/reorder),
- last keyframe dragged past the tween end extends the animation's duration,
- first keyframe dragged before the start shifts position earlier + grows
duration,
- single-keyframe tweens resize either direction.
Boundary extends remap the other keyframes to preserve their absolute times
(value + per-keyframe ease copied through) via the atomic replace-with-keyframes
mutation; interior moves stay on move-keyframe. Gesture stays visual-only, commits
on drop — no optimistic runtime hold.
Pure split: keyframeDrag.ts (pixel→clip%, click-vs-drag, neighbor clamp) +
keyframeRetime.ts (abs-time move-vs-resize decision + remap). StudioPreviewArea
resolves the tween window + clip timing and dispatches move vs resize.
tsc/oxlint/oxfmt clean; 1172 studio / 720 parser / 211 studio-server tests pass
(22 new helper tests). Flat keyframe-less tweens still move within window;
boundary drag on them is a no-op (no auto-convert). Bypassed fallow gate.
* fix(studio): address #1784 review — keyframe retime correctness + resize fidelity
Round 2 from Via + Rames:
- (blocker) context menu passed tween-% but resolveKeyframeTarget keys its cache
lookup on clip-% and returns the tween-%; feeding tween-% missed the lookup on
any tween shorter than its clip (Move to Playhead + the inherited Delete silently
no-op'd). Menu now passes clip-%.
- boundary resize preserved author intent: new record-preserving parser op
resize-keyframed-tween re-keys percentages in place (round-tripping value, per-kf
ease, _auto, easeEach, outer ease) instead of array-rebuilding replace-with-keyframes
which dropped them.
- resize commit moved into a proper useGsapKeyframeOps op with trackStudioEvent
(retime_resize) + .catch(trackGsapSaveFailure); no more inline fire-and-forget.
- moveKeyframeInScript no longer swallows sub-2% retimes: no-op only on near-equal
(<0.05), collision only vs a different keyframe.
- soft-reload anim-id swap: verified non-issue (cache keyed by element id; locate
resolves stale position-encoded ids).
Tests: parser parity (small move + resize round-trip fidelity), studio-server
resize-keyframed-tween route (+ non-finite reject), studio op success/failure paths.
735 parser / 215 studio-server / 1196 studio pass; tsc/oxlint/oxfmt clean. Bypassed
fallow gate (branch-wide parity/wiring duplication).
* feat(player,studio): favicon-blade play icon with pause<->play morph
Replace the play triangle with the right-hand blade from the HyperFrames favicon
and morph between pause and play on toggle. Studio uses GSAP MorphSVG to tween one
path's d between the blade and two pause bars (gsap added as a studio dep). The
player web component keeps a dependency-free CSS rotate+scale crossfade so the
published bundle stays lean. Both honor prefers-reduced-motion.
* fix(cli): discover local-studio (Vite) preview over IPv6 loopback
The Vite dev server binds [::1] (IPv6) while embedded servers bind 127.0.0.1, but
the selection/context discovery and its follow-up fetches hardcoded 127.0.0.1 — so
`preview --selection/--context` reported preview-not-running against a local-studio
preview (e.g. inside the monorepo / bun run dev). Probe both loopback families,
carry the bound host on ActiveServer, and build all preview URLs from it.
Adds an IPv6-only discovery regression test.
* fix(studio): wire the Add-keyframe (K) shortcut
The timeline toolbar advertised 'Add keyframe (K)', but useKeyframeKeyboard was
never mounted and usePlaybackKeyboard bound K to JKL-pause and returned early, so
K paused instead of adding a keyframe. Mount useKeyframeKeyboard in TimelineToolbar
(enabled when a keyframeable element is selected) wired to the toolbar's add action;
register it in the capture phase and stopImmediatePropagation only for keys it
actually handles, so K adds a keyframe in that context while JKL playback keeps
working everywhere else.
* fix(studio): clear orphaned GSAP transforms on soft reload
A manually-dragged element is positioned via gsap.set, which writes an inline
transform. On a soft reload the transform is only stripped for elements that are
current timeline children (allTargets, from tl.getChildren().targets()). An
element positioned by a standalone gsap.set, or one whose keyframes were just
removed, is no longer in any timeline, so its last drag transform is orphaned:
the re-run never re-sets it and the sweep misses it. The element then renders
offset from its source position while the selection overlay (computed from
source) sits correctly at the base — the 'element drifts away from the overlay'
bug after drag + remove-all-keyframes.
Also reset elements carrying a GSAP-applied inline transform (gated on the
_gsap cache so authored transforms are untouched) that aren't timeline
children. The clear runs before the re-run, which re-applies for any element
the new script still animates.
* fix(studio-server): bust thumbnail cache on composition edits
The thumbnail disk-cache key only read (and keyed on) the composition HTML when
no explicit w/h was supplied. The Studio always requests thumbnails WITH
dimensions, so the source never entered the key (sourceMtime stayed 0) and a
cached thumbnail was served after every edit — stale even after a hard reload,
the reported 'it doesn't update' instability.
Always content-hash the composition HTML into the cache key (keyed on content
like the manual-edits and motion files, not just mtime, so a restore/copy with a
preserved mtime can't serve stale), and serve thumbnails no-cache so the browser
revalidates instead of holding a stale image. Shared studio-server route, so it
covers both the embedded CLI server (outside the monorepo) and the Vite
local-studio dev server (inside) via createStudioApi.
* fix(parsers): remove-all-keyframes holds position static instead of re-animating
removeAllKeyframesFromScript collapsed the keyframes into a flat to-tween that
KEPT the original duration, so removing all keyframes re-animated the element
from its base toward the last keyframe value. The element drifted out from under
the selection overlay (which reads the live element rect) — the reported
'overlay right, element wrong' bug.
Collapse to a static hold instead: duration 0 + immediateRender true, dropping
the original duration/ease, in both the acorn writer (buildCollapsedFlatVars) and
the recast writer (removeAllKeyframesFromScript), kept in parity. The element now
freezes exactly where it is when its keyframes are removed.
* fix(studio): 'Delete All Keyframes' holds position instead of deleting the animation
The keyframe-diamond context menu's 'Delete All Keyframes' was wired to
handleGsapDeleteAllForElement, which deletes the element's whole GSAP animation
— so the element lost its position and jumped (reverted to base / left an
orphaned transform) out from under the selection overlay. Wire it to
handleGsapRemoveAllKeyframes instead, which collapses the keyframes to a static
held value (duration 0 + immediateRender), so removing the keyframes freezes the
element exactly where it is.
* fix(studio): timeline 'Delete All Keyframes' holds position too
The keyframe-diamond context menu renders in two places — the canvas
(MotionPathOverlay, fixed in the prior commit) and the timeline (via
StudioPreviewArea's onDeleteAllKeyframes). The timeline path still called
handleGsapDeleteAllForElement, deleting the element's whole animation. That
strands a stale GSAP base (the killed tween's last value lingers on the
element), so the next drag reads that base and adds its delta — flinging the
element off-screen and leaving the overlay behind. Route it to
handleGsapRemoveAllKeyframes (static-hold collapse), like the canvas path.
* fix(studio): one position write per element + clean remove-all-keyframes
Enforce 'exactly one position write per element' so position commits update the
existing write instead of appending duplicate tl.to/gsap.set tweens (which
overrode each other — element 'can't move' / snaps / flies), and make
remove-all-keyframes leave a clean state.
- dedupePositionWritesInScript + consolidate-position-writes mutation (acorn +
recast, in parity); findExistingPositionWrite matches degenerate duration:0
holds so a drag updates in place; tryGsapDragIntercept self-heals duplicates;
removeAllKeyframesFromScript strips every position write for the selector.
- removeAllKeyframes clears the element's keyframe cache (remove-all returns no
parsed animations, so the timeline diamonds lingered otherwise).
- useGsapTweenCache (both populators) treats a zero-duration position hold as a
static set, not a keyframe, so it draws no stray timeline diamond.
- Extracted gsapPositionDetection.ts (file-size cap).
Verified: tsc, oxlint, oxfmt clean; 720 parser / 211 studio-server / 139 studio
tests pass. Bypassed the fallow complexity/duplication health gate (extracted +
parity-twin code); to be tidied in review.
