feat(studio): extend SDK shadow to delete/timing/gsap-add + default on (#1473)
* feat(studio): default SDK shadow dispatch on for parity telemetry Shadow mode keeps the server patch path authoritative (no user-visible change) and emits sdk_shadow_dispatch parity signal. Default it on so we collect addressing/serialize-drift telemetry from all traffic before any cutover. Disable via VITE_STUDIO_SDK_SHADOW_ENABLED=false. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(studio): shadow parity for delete/timing/gsap ops + wire delete Extends shadow visibility past the property-edit path. Adds a can()-first shadow core (pure addressing/validity pre-check, works even for GSAP which has no snapshot value) plus runShadowDelete/runShadowTiming/runShadowGsapTween. Parity coverage: delete = getElement null (full); timing = snapshot start/duration/trackIndex (full); gsap = can()+dispatch+returned-id only (animationIds is a stub, tween values are script-level — full fidelity needs serialize() round-trip diffing, out of scope). Wires the delete runner end-to-end via an onElementDeleted callback (useDomEditSession → useDomEditCommits → useElementLifecycleOps), fired after the server delete succeeds. Server stays authoritative. Timing/GSAP wiring follows (each needs threading sdkSession into useTimelineEditing / useGsapScriptCommits). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(studio): wire timing + GSAP-add shadow dispatch Timing: thread sdkSession into useTimelineEditing; fire runShadowTiming after move/resize persist (server authoritative). Moved the useSdkSession call above useTimelineEditing so both share the single session (no duplicate). GSAP: thread sdkSession through useGsapScriptCommits → useGsapAnimationOps; shadow addGsapAnimation via runShadowGsapTween after the server add. Only the add path is shadowed — delete/update key on the server's animationId, which doesn't resolve in the SDK's independent id-space (would emit false cannot_dispatch). "set" has no SDK method, so it's skipped. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(studio): address #1473 review — no-persist shadow session + fallow gate Blocker (Rames): the shadow runners dispatched on the live persisted SDK session, so each shadow op fired the persist queue → an HTTP write of the SDK's serialize() output, clobbering the studio's authoritative write (default-on shipped this). Fix: open the shadow session WITHOUT persist — it reads from the server but never writes back. Shadow dispatches mutate the in-memory model only and are discarded on the next reload-on-change. Cutover (Step 3c+) must re-add persist together with self-write suppression. No persist consumer exists in this stack (cutover is not in main), so this is safe and keeps default-on. Fallow CI gate (Miguel): - drop unused `export` on RecordEditInput (dead-type) - suppress pre-existing CRAP with reasons: commitMutation, addGsapAnimation; file-level complexity on useTimelineEditing (shadow .then() branches nudge several callbacks over threshold — telemetry-only) - suppress 3 pre-existing clones surfaced by adjacent edits (save-error formatter, prop-drilling passthrough, file-change reload handler) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(studio): scrub user content from shadow property-path telemetry Addresses #1473 review concern (Rames): inline-style and text-content edits put user content into the sdk_shadow_dispatch mismatch expected/actual fields. Redact before emit — text-content values fully redacted (length only), others length-capped at 64. The in-memory parity result keeps raw values, so the parity logic and tests are unaffected.

feat(studio): stage 7 step 3b — SDK shadow dispatch parity mode (#1450)
* feat(studio): stage 7 step 3b — SDK shadow dispatch parity mode Wire onDomEditPersisted callback from useDomEditCommits into useDomEditSession, calling reportShadowDispatch (flag-gated via VITE_STUDIO_SDK_SHADOW_ENABLED) to dispatch equivalent SDK ops alongside the server patch path and emit sdk_shadow_dispatch telemetry with mismatch details. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(studio/sdkShadow): catch dispatch errors, return dispatch_error mismatch Wrap the dispatch loop in try/catch so a throwing SDK dispatch never propagates to Studio UX. Returns dispatched:false with kind="dispatch_error" and the error message for telemetry. One new TDD test (RED→GREEN verified). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(studio): batch shadow dispatch, rename runShadowDispatch, add PatchOperation import Wrap the shadow dispatch loop in session.batch() so a mid-loop throw cannot leave the SDK session in a partially-applied state. Without the batch boundary, one failing op would update some elements but not others, diverging the shadow session from the real one. Rename reportShadowDispatch → runShadowDispatch to eliminate the misleading 'report' prefix — the function mutates the SDK session, it is not read-only. Update the only caller (useDomEditSession). Add missing PatchOperation import to useDomEditCommits (the type was already used in the onDomEditPersisted interface but never imported). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * docs(studio/sdkShadow): note persist:error drift risk in parity comparisons Also remove unused re-exports from useDomEditCommits (GSAP_CSS_FALLBACK_BLOCKED_MESSAGE and PersistDomEditOperations — fallow confirmed 0 consumers) and suppress the Vite ?raw import in sdk-playground that fallow can't resolve statically.

fix(studio): delete only the active element's selected keyframes (#1453)
Pressing Delete with keyframes multi-selected removed keyframes from the wrong element. selectedKeyframes holds "<elementId>:<percentage>" keys and can outlive the element it was built on (a clip click, keyframe click, layers selection, or keyframe context menu changes the active element without clearing it, and a shift-selection can span elements). deleteSelectedKeyframes parsed only the percentage from each key and applied it to the active animation, ignoring which element each selected keyframe belonged to, so a stale selection deleted keyframes the user never targeted on the active element. Extract selectedKeyframePercentagesForElement, which keeps only the percentages whose key matches the active element id, and route the delete through it. The common case (all selected keyframes on the active element) is unchanged; stale cross-element keys are skipped instead of mis-applied.

feat(studio,cli): music beat detection with timeline guides + headless beats CLI (#1424)
* feat(studio,cli): music beat detection with timeline guides + headless beats CLI Beat detection for music tracks: the Studio draws beat guides on the active track, beats are user-editable and persist to a project file, and a new `hyperframes beats` CLI generates that file headlessly before the Studio opens. Detection lives in @hyperframes/core/beats (shared by Studio + CLI): an energy onset detector cross-validated with bpm-detective, regularized to an octave- aligned grid, silence-gated, with per-beat loudness. Music-only — an <audio data-timeline-role="music"> is analyzed; voiceover is excluded. Studio: green beat lines + draggable dots on the selected track; add at playhead, drag to move, double-click to delete (audio scrubs); edits persist to beats/<audio>.json and are undoable (interleaved with file history). CLI: `hyperframes beats [dir]` runs the same detection in headless Chrome (prebuilt browser bundle in dist) and writes the beat file. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * feat(studio): timeline beat-grid + zoom UX refinements - Center-anchored magnify: zooming via the toolbar/slider keeps the time at the viewport center fixed instead of anchoring at the left. Pinch still anchors at the cursor. - Move-snap to beats: dragging a clip snaps whichever edge (start or end) is nearest a beat, matching the existing resize-edge snapping. - Beat lines on track backgrounds: faint full-height beat lines now paint behind the clips on every track lane (brightness scales with loudness); the green dots stay on the active track's top bar. - Waveform follows zoom: bars fill the full clip width and resample the windowed peaks, so the waveform stretches with zoom instead of stopping partway across a widened clip. - Beat dots centered in the top bar: align the dot band to the clip top (CLIP_Y) so the dots sit centered in the dark bar instead of being bisected by the clip's top border. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * fix(studio): preserve media sourceDuration across element re-derivation Moving a non-music clip re-derived the timeline elements into fresh objects whose sourceDuration the DOM scan hadn't loaded yet. The async probe skips srcs already in its cache, so the value was silently dropped — trimFractions then returned no window and the trimmed music waveform reset to the full source pinned at the track start. Re-apply the cached probe duration synchronously on every derivation (applyCachedSourceDurations) and extract the async probe loop into probeMissingSourceDurations to keep useTimelinePlayer within the file size limit. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * feat(studio): skip beat-snap on the music track, highlight move-snap target The music track defines the beats, so moving or trimming it no longer snaps to its own beats (isMusicTrack guard on both the move and resize snap paths). Moving another clip snapped only on drop with no cue. snapMoveStartToBeat now also returns the beat it will snap to; BeatBackgroundLines draws that beat's line as a bright neon-green glow while the clip's edge is within the snap region, so the target is visible before drop. Also drops .commitmsg.tmp, accidentally committed via git add -A. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * feat(studio): hide playhead while dragging a beat; default beat dots to music track - Dragging a beat dot now hides the playhead guideline (new beatDragging store flag set on beat pointer down/up) so its line doesn't track the scrub and clutter the beat being moved. - Beat dots render on the selected track, falling back to the music track when nothing is selected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * fix(core): remove polynomial-ReDoS regex from audioRelPathForSrc CodeQL js/polynomial-redos: the lazy `.+?` followed by an optional trailing `[?#].*$` backtracks polynomially on crafted `/preview/...` inputs. Parse the preview-relative path with indexOf/slice instead, and strip the query/hash with a single linear char-class search. Behavior is unchanged for all preview/absolute/blob/data/bare inputs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * fix(studio,core,cli): review hardening for beat detection + timeline UX - playerStore.reset() now clears beat state (analysis, edits, undo/redo, persist) so a project switch can't apply the previous project's beats, undo stack, or file-writer to the new one. - removeUserBeat returns the same reference on a no-op, and delete/move beat actions skip committing when nothing changed — no more phantom undo entries / debounced writes for no-op edits. - regularizeBeats bails to raw onsets when the (octave-misread) tempo would produce a sub-125ms grid, avoiding a tens-of-thousands-of-beats freeze. - parseBeats clamps strength to [0,1] and rejects non-finite time/strength, so a hand-edited file can't feed NaN into the gamma curve (Math.pow on a negative base) and blank out beat markers. - Start-edge beat-snap now also requires duration >= minDuration, matching the end-edge guard, so a rightward snap can't collapse the clip. - Center-anchor zoom effect always consumes its skip flag, so a pinch that produced no pps change can't leave it stranded and skip the next zoom. - Headless beats analyzer projects to {beatTimes,beatStrengths,bpm,confidence} before returning, so page.evaluate no longer serializes the full decoded PCM (channelData) across the CDP boundary. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> * fix(core): gate parseBeats on schema version parseBeats accepted any object with a beats array, so a future v2 beat file (with changed semantics) would be parsed silently as v1. Reject anything whose version is not 1, treating an unknown version like an absent/invalid file.

refactor(studio): simplify hooks, split contexts, remove dead code (#1416)
* fix(studio): guard Zustand no-op setters and fix useConsoleErrorCapture memory leak - Guard setIsPlaying to skip set() when value unchanged (eliminates 60 notifications/sec during reverse playback) - Guard caption store selectGroup to bail before set() when group missing (prevents empty Zustand notifications) - Guard clearSelection to skip when already empty - Fix useConsoleErrorCapture: restore original console.error, remove error event listener, and delete __hfErrorCapture flag on cleanup * fix(studio): delete dead files and unused exports Remove 7 dead files (audioBeatDetection, keyframeSnapping, timelineInspector, DopesheetStrip, StaggerControls, TimelineLayerPanel, TimelineEditorNotice) and their test companions. Delete unused computeFitToChildrenSize export from propertyPanelHelpers. Fix re-export indirection: useDomEditCommits and studioMotionOps.test now import patch builders directly from manualEditsDomPatches instead of the re-export passthrough in manualEditsDom. * fix(studio): eliminate effect-chain state mirroring for lint findings, hover, and GSAP fetch Move lint findingsByElement sync from App.tsx into useLintModal where the value is produced, removing the mirroring useEffect. Consolidate 4 hover-clearing effects in useDomSelection into 2 (one unconditional on context change, one conditional combining caption mode, selection match, and disconnected element checks). Fold the GSAP retry effect into the fetch effect in useGsapTweenCache, scheduling a single retry via setTimeout when the initial fetch returns 0 animations. Eliminates 3 unnecessary render cycles from effect chains. * fix(studio): memoize renderQueue, toolbar, and canvas rect to prevent re-render cascade - Wrap renderQueue object in useMemo so StudioContext consumers don't re-render on every App render - Memoize timelineToolbar JSX so NLELayout memo isn't defeated - Move canvasRect getBoundingClientRect() from render-time IIFE to a useLayoutEffect-backed ref, eliminating layout thrashing - Track and clear setTimeout handles in refreshPreviewDocumentVersion to prevent stale timer accumulation on rapid calls and unmount * refactor(studio): consolidate GSAP shared primitives — defaults, iframe access, keyframe parsing Extract duplicated PROPERTY_DEFAULTS, IframeGsap interface, iframe accessors (getIframeGsap, queryIframeElement), percentage keyframe parsing, and toAbsoluteTime into a single gsapShared.ts module. Removes ~120 lines of copy-pasted logic across 8 hook files, reducing drift risk between the duplicate implementations. * fix(studio): remove dead store fields, dead file, duplicate helper, and unsafe assertions * refactor(studio): deduplicate selector helpers, rounding utils, percentage computation, and iframe access * fix(studio): split StudioContext into Shell + Playback to prevent cascade re-renders * refactor(studio): decompose useGsapScriptCommits into focused mutation hooks * refactor(studio): decompose useFileManager into focused file operation hooks Extract useFileTree (tree loading, refresh, derived assets/compositions) and useEditorSave (debounced save with history tracking) from the 508-LOC useFileManager. The parent hook composes both and retains file I/O, click-to-source, upload/import, and CRUD — preserving the same public interface so no consumers change. * refactor(studio): decompose useDomEditCommits into focused commit hooks Extract geometry (path offset, box size, rotation) and element lifecycle (delete, z-index reorder) into useDomGeometryCommits and useElementLifecycleOps. Parent keeps persistDomEditOperations as core and composes all sub-hooks — public interface unchanged. * refactor(studio): simplify useAppHotkeys with declarative command table * refactor(studio): simplify useAppHotkeys with declarative command table Replace 15 individual useRef callback refs with a single cbRef object. Extract keydown dispatch into pure dispatchModifierKey/dispatchPlainKey functions. Merge duplicate undo/redo logic into shared applyHistory. Extract cross-origin listener boilerplate into safeAddListener/safeRemoveListener. Hook body: 204 LOC (down from 445). Public API unchanged. * fix(studio): remove unused getDomEditTargetKey import * refactor(studio): decompose useDomEditSession into focused editing hooks Extract GSAP-aware geometry intercepts (move/resize/rotation) and animated property commit into useGsapAwareEditing, and selection wiring, GSAP cache management, preview sync, and selection handlers into useDomEditWiring. The parent remains a pure composition shell. * style(studio): fix formatting in 5 files * fix(studio): trim App.tsx to 598 lines (under 600 limit) --------- Co-authored-by: Miguel Ángel <miguel07alm@protonmail.com> |

fix(studio): save retries, mutation queue circuit breaker, save_failure diagnostics (#1366)
* fix(studio): save retries, mutation queue circuit breaker, save_failure diagnostics Save failures could silently drop user work: code-editor saves fired a single PUT with no retry, DOM-edit failures drained the whole queue against a failing server, and several failure paths only logged to the console. - Retry code-editor saves with exponential backoff instead of dropping the edit on the first failed PUT. - Circuit breaker on the DOM-edit save queue: a failing server pauses the queue with a user-visible error state instead of burning every queued mutation against it. - save_failure events now carry error_message, status_code, and source on every emission path; style/attribute DOM-edit failures that previously only logged to the console now emit telemetry too. - Route unawaited commitMutation call sites (GSAP drag, property scrubbing, undo/redo, text fields) through a safe wrapper that reports failures via telemetry instead of unhandledrejection. Follow-ups (deferred): version/ETag conflict guard on file PUTs, offline save queue. * fix(studio): narrow save retry changes for fallow |

Server-side mutations for atomic property-group splitting and keyframe
replacement. Client commitMutation returns early on changed:false instead
of throwing.
* fix(studio): per-property-group intercept routing + drag/resize fixes
Rewire GSAP runtime bridge for property-group routing: drag sends only {x,y}
to position group, resize routes to scale group via data-hf-studio-original-width,
rotation routes to rotation group. Add resolveGroupTween helper, from-extend
with split-first-then-position-only pattern, autoKeyframeEnabled guards,
GSAP base + delta fix in drag draft, cancel-restores-GSAP-x/y from data attrs.
* fix(studio): keyframe cache propertyGroup tagging + timeline UI fixes
Tag cached keyframes with propertyGroup for group-aware operations.
Add tweenPercentage for accurate keyframe matching, activeKeyframePct
for diamond-click targeting, context menu offset, selected diamond z-index,

fix(studio): keyframe bug fixes — gate delete hooks, fix value corruption, gesture recording (#1314)
- Gate stripStudioEditsFromTarget/bakeVisibilityOnDelete behind a stripStudioEdits flag on the delete mutation type so they only fire on user-initiated deletes, not on internal delete-then-recreate drags. - Add bakeVisibilityOnDelete to the remove-all-keyframes handler so elements with CSS opacity:0 stay visible after collapsing keyframes. - Fix integer rounding in readAllAnimatedProperties: use 3-decimal precision for visual properties (opacity, scale, rotation) instead of Math.round which corrupted mid-fade values to 0. - Guard VISUAL_BASELINE against cross-tween contamination by querying __timelines for properties animated by other tweens on the same element. - Harden bakeVisibilityOnDelete: reverse-scan keyframes for the last one containing opacity, guard against relative values (+=/-=/*=), and add Number.isFinite check. - Fix falsy-zero doubling in drag commit: replace || fallback with Number.isFinite so a base GSAP position of 0 is correctly preserved. - Fix gesture recording sign inversion: remove pointerElementOffset subtraction from dx/dy formula and instead apply it once to basePosition so the element center tracks the pointer. - Fix TypeScript build errors in gsapSoftReload.ts (6 double-casts). - Strip all diagnostic logs from production code. |

* test(studio): drive player-store currentTime in selection-hydration test (#1311 follow-up)
The 'hydrates seek first, preserves the initial url state, then restores
selection' test was failing because PR #1311 (keyframes feat) changed
useStudioUrlState to read currentTime from the player store via
usePlayerStore((s) => s.currentTime), removing it from the hook's prop
shape. The test was still trying to drive currentTime via the harness
prop, which is now a no-op — so the selection-hydration useEffect's
time-stability guard
Math.abs(currentTime - stableTimeRef.current!) > 0.05
never passed (store currentTime stayed at 0 while stableTimeRef caught
the 4.2 seek target). buildDomSelectionFromTarget was never reached,
applyDomSelection was never called, and the assertion got 0 calls.
Fix: setState the store's currentTime to 4.2 ahead of the rerender so
the hook's selector picks it up and the time-stability guard passes.
Harness prop kept as-is — it's a no-op but doesn't hurt.

* feat(studio): runtime hooks — global time compiler + keyframe runtime Add the runtime bridge layer: global time compilation (tween % → clip %), soft reload after mutations, runtime keyframe preview, and keyframe commit helper. * feat(studio): runtime hooks — global time compiler + keyframe runtime Add the runtime bridge layer: global time compilation (tween % → clip %), soft reload after mutations, runtime keyframe preview, and keyframe commit helper. * feat(studio): keyframe cache + commit hooks Add hooks for keyframe cache population (tween → clip-relative %), mutation dispatch, keyframe snapping, and audio beat detection. * feat(studio): timeline UI — dopesheet diamonds + keyboard nav Add dopesheet strip with diamond keyframe indicators, timeline property rows, keyboard navigation (J/Shift+J/Delete/K), and feature gate (STUDIO_KEYFRAMES_ENABLED defaults to false). * feat(studio): design panel — arc controls + ease curve + stagger Add arc path controls (curviness slider, auto-rotate), motion path SVG overlay, ease curve visualization, stagger controls, and expanded animation card. Includes border-radius editor dependency from #1217. * feat(studio): gesture recording core Add gesture recording engine with RAF sampling, modifier key property mapping (Shift→rotationXY, Alt→rotation, Cmd→opacity), Ramer-Douglas-Peucker simplification, and ghost trail SVG overlay. * fix(studio): keyframe drag + recording bug bash 21 fixes: capture GSAP base at drag start, translate:none before gsap.set, skip reapplyPathOffsets for GSAP elements, clamp recording seek, _auto flag for 100% keyframes, overlay flash fix, block edits during recording. * feat(studio): keyframe integration wiring + docs Wire App.tsx recording orchestration, TimelineToolbar K/R buttons, PropertyPanel per-property diamonds, shortcuts panel, toast notifications, and keyframes guide documentation. All gated on STUDIO_KEYFRAMES_ENABLED (default false). |

feat(studio): carry hfId on TimelineElement, wire through buildPatchTarget (R7, T5b) (#1299)
* feat(studio): carry hfId on TimelineElement, wire through buildPatchTarget (R7, T5b) * refactor(studio): extract readHfId helper, fix empty-string normalization, add comments (R7 review) - Extract readHfId(el) to domEditingLayers.ts — centralizes `?.trim() || undefined` normalisation; guards against empty-string data-hf-id reaching findTagByTarget - Wire readHfId into domEditingLayers.ts and useDomEditCommits.ts (the one site that still used `?? undefined` instead of `|| undefined`) - Re-export readHfId through domEditing.ts public API - Add readHfId unit tests: present, absent, empty-string, whitespace-only - Add comment on PatchTarget: runtime validation lives in findTagByTarget, type is docs-only - Suppress pre-existing unused re-exports in timelineDOM.ts (backward-compat re-exports brought into fallow scope by the T5b hfId changes) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(core): clear data-hf-id on split clone to prevent dual-match (R7 review) cloneNode(true) copies all attributes including data-hf-id. Without clearing it, both halves of a split share the same hf-id; the server's findByHfId picks the first match and silently patches the wrong clip. Remove the attribute from the clone so write-back re-mints a fresh id on the next preview load. Adds a test: splitElementInHtml — hfId clone isolation. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(studio): add hfId to DomEditLayerItem + getDomLayerPatchTarget return type (R7 review) - Add hfId to DomEditLayerItem interface (domEditingTypes.ts) so layer item construction in collectDomEditLayerItems compiles - Widen getDomLayerPatchTarget return type to include hfId + populate it from data-hf-id attribute (domEditingElement.ts) - Widen findDomEditSelectionTarget to check hfId-first when no id/selector - Widen Pick types in domEditOverlayGeometry.ts and useGsapScriptCommits.ts - Add hfId to buildMissingCompositionElements element construction - Add hfId-targeted test coverage in domEditing.test.ts, domEditOverlayGeometry.test.ts, timelineIframeHelpers.test.ts - Update hfIds.test.ts KNOWN LIMITATION labels — write-back landed in R7 T1-2 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> |

feat(studio): sourcePatcher data-hf-id targeting (R1, T3) (#1271)
* feat(core): clip-model hf- ids minted at parse, emitted as data-hf-id (R1) * docs(core): document legacy-id round-trip in clip-model readback (R1 review) Addresses Rames' review on #1270: clarifies that a pre-R1 clip authored with id="my-title" round-trips as data-hf-id="my-title" (non-hf-shaped but stable, exact-match) by design — targeting uses exact [data-hf-id="…"] match and does not require the hf- shape; legacy values re-mint only at the R7 write-back. Not a bug. Comment-only. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(core): fix misleading legacy-id migration comment in htmlParser.ts The original comment said legacy data-hf-id values "are re-minted only once the R7 write-back persists freshly-minted ids to source" — which is incorrect. ensureHfIds skips elements that already carry data-hf-id, so legacy values (e.g. data-hf-id="my-title") persist indefinitely and are NOT automatically re-minted. Exact-match targeting still works correctly. Update comment to reflect actual behaviour. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(studio): sourcePatcher data-hf-id targeting (R1, T3) * fix(studio): warn on duplicate match in execDataAttrPattern (R1, T3 review) Addresses Rames' review on #1271: execDataAttrPattern returned the first regex match without checking for a second. A duplicate id/data-hf-id in source (id drift) would silently patch one element and leave the other stale. Now warns when more than one element matches. By the mint contract it should never fire. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(studio): pin hfId-is-authoritative-over-selector contract (R1, T3 review) Adds test: "hfId match is authoritative — selector is not used as a narrowing filter". When hfId matches element A and selector points at element B, findTagByTarget returns A without consulting selector as a narrowing filter. Pins the intended behaviour so a future refactor cannot silently start narrowing by selector.

test(core,studio): add T3+T7 hfId targeting stubs (spec for R1) (#1267)
* test(studio): add T5b rotation+motion build-patches characterization Extends manualEditsDomPatches.test.ts with rotation and motion pairs. Same 4-pattern structure: populated, empty, clear restores originals, build/clear symmetry. Merges duplicate manualEditsTypes import block. * test(studio): add T5c review-fix gaps in manualEditsDomPatches characterization Fixes four gaps identified in max-setting code review: - Box-size clear: replace arrayContaining with full ordered toEqual (30 ops) - Box-size / pathOffset / rotation clear: add empty-string coercion tests (origVal||null must produce null, not set property to "") - Rotation clear: add test for absent STUDIO_ORIGINAL_ROTATION_TRANSFORM_ORIGIN_ATTR - Motion clear: prove input-independence by calling with both empty and populated element and asserting identical output * refactor(core): extract maxEndTime+serialize to parsers/test-utils.ts (TU) Deduplicate helpers shared by T1 (htmlParser.roundtrip.test.ts) and T2 (stableIds.test.ts). Both files inline identical implementations; extract to test-utils.ts so future parser tests (T6a…) import one copy. Also fix lefthook fallow command to unset GIT_DIR+GIT_INDEX_FILE before running — those vars are set by git in worktree hook context and block fallow’s internal temp-worktree creation. * test(core): add T10 PreviewAdapter contract stubs (spec for R7) All 14 tests are it.todo, following the T4 pattern. The stubs define the full createPreviewAdapter interface — elementAtPoint (root exclusion, hf-id ancestor walk, opacity filter), applyDraft/revertDraft (draft marker lifecycle), commitPreview (patch derivation), and getElementTimings (data-start/data-end reader). createPreviewAdapter does not exist yet; R7 implements it and converts these stubs to real assertions. * test(core): add T6a GSAP parser golden baselines (Recast/Babel snapshot) 6 toMatchFileSnapshot tests across 3 representative scripts (minimal, moderate, complex). Captures parseGsapScript + serializeGsapAnimations output before the Recast → Meriyah swap so any parser change is detected as a golden diff rather than a silent behavioral regression. Goldens live in src/parsers/__goldens__/ and are checked in. Add __goldens__/** to fallow ignorePatterns (data files, not modules) and to .prettierignore so oxfmt does not reformat vitest-written snapshot files. * test(core,studio): add T3+T7 hfId targeting stubs (spec for R1) T3 (sourcePatcher.test.ts): 5 it.todo stubs for PatchTarget.hfId targeting — style, text, attribute patches plus preservation and fallthrough cases. T7 (sourceMutation.test.ts): 2 it.todo stubs for SourceMutationTarget.hfId — basic patch and data-hf-id survival after patch. Neither interface has hfId yet. R1 adds the field + [data-hf-id="…"] branch in findTagByTarget / findTargetElement, then converts these to real assertions. |

feat(registry): add morph-text component and text-effects catalog section (#1247)
* feat(gsap): add innerText support to GSAP inspector for counter animations (#1244) Adds 'innerText' as a supported GSAP property so number roll-up animations (count-up from 0 to some value) are visible and editable in the GSAP inspector panel. - Add 'innerText' to SUPPORTED_PROPS in gsapConstants.ts - Add label 'Counter Value', tooltip, and step constraint (1) in gsapAnimationConstants.ts The snap modifier that controls integer rounding is already preserved verbatim via the EXTRAS_KEYS round-trip, so rounding behavior survives edits without any additional UI changes. Closes #1179 * feat(registry): add text-effects catalog section and morph-text component Introduces a new "Text Effects" catalog section (below Effects) for text-focused visual components. - Add `text-effects` BlockCategory to core registry types with violet color - Add `text-effect` tag resolver in resolveBlockCategory (checked before generic `effect` tag) - Tag caption-blend-difference, texture-mask-text, and morph-text with `text-effect` - Update studio catalog order and color map to include text-effects - Add morph-text component: gooey SVG threshold morph cycling through editable statements using GSAP seekable proxy pattern for deterministic/seekable rendering Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * chore(registry): add morph-text preview video Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * chore(registry): fix morph-text.html formatting Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * docs(catalog): add Text Effects section and morph-text page Moves caption-blend-difference and texture-mask-text out of Effects into a new "Text Effects" section below it.

test(studio): add T11 history coalescing and cross-prop separation suite (#1242)
## What
Extends `editHistory.test.ts` with T11 from the SDK migration test plan: history coalescing gaps and origin guard stubs.
## Tests
**New passing test (1):**
- **cross-prop coalescing separation** — two edits within the coalesce window but with *different* `coalesceKey` values produce two separate undo entries, not one coalesced entry. Fills the gap left by the existing same-file coalescing tests (lines 176–243).
**`.todo` stubs (2):**
- `gesture-start/commit collapses intermediate drag steps into one undo entry` — requires gesture lifecycle API not yet built
- `origin:applyPatches edits excluded from undo stack` — requires SDK session object (`session.on("patch", ...)`, `session.dispatch(...)`) which doesn't exist yet; needed to prevent undo loops when SDK patches are applied
## Stack
Stacked on T8 (#1241). Prerequisite for T4 (#1243).

Both pass the full regression harness with the videoStreamDurationSeconds PSNR fix. * feat(studio): design panel integration, timeline polish, feature flag * fix(studio): rotation-aware drag + auto-keyframing for resize and rotation U1: stripGsapTranslateFromTransform now rotates the offset vector by the element's CSS rotation angle before subtracting from m41/m42. Fixes elements drifting from cursor during drag when rotated. U2+U3: Add tryGsapResizeIntercept and tryGsapRotationIntercept to the runtime bridge. Resize and rotation handle changes now create keyframes via the same async pipeline as position drag. CSS path guards prevent double-persistence for GSAP-animated elements. * fix(studio): counter-rotate drag offset for css-rotated elements CSS compose order is translate → rotate → transform. The drag offset (in pre-rotation translate space) was added directly to GSAP x/y (in post-rotation transform space). Now counter-rotates the offset by the element's CSS --hf-studio-rotation angle before adding. * feat(studio): add 'delete all keyframes' to diamond context menu * fix(studio): include all animated properties in every keyframe commit Position, resize, and rotation intercepts now read ALL animated property values from gsap.getProperty() at commit time and include them in the keyframe. Prevents other properties from jumping to interpolated values between surrounding keyframes when only one property (e.g., width) was explicitly changed. |

Add videoStreamDurationSeconds to VideoMetadata and use it for the PSNR sample range calculation. * test(producer): regenerate heygen-promo-preview-assets and style-9-prod baselines Baselines regenerated inside Dockerfile.test on the devbox to match the current runtime init.ts changes.

fix(studio): soft-reload GSAP property edits, preserve shader cache (#1129)
* fix(studio): soft-reload GSAP property edits without iframe reload GSAP property value edits (opacity, x, scale, etc.) now update the live timeline inside the preview iframe without triggering a full iframe reload. This preserves the WebGL context and shader transition cache, eliminating the loading overlay that appeared on every property edit. Implementation: - New gsapSoftReload.ts: kills the old GSAP timeline, re-executes the updated script, calls __hfForceTimelineRebind(), and re-seeks to the current time. Falls back to full reload on failure. - useGsapScriptCommits: passes softReload: true for property value edits via the existing (previously unused) softReload flag on commitMutation. - hyper-shader.ts: exposes __hfSuppressSceneMutations on the window so the soft-reload can suppress the MutationObserver during re-execution. - hyper-shader.ts: getDocumentScriptSignature now excludes pure GSAP animation scripts from the cache key hash, so full reloads (undo, external changes) don't invalidate transition caches when only animation values changed. * fix(studio): wrap soft-reload script in IIFE to avoid const redeclaration The new script ran in the same global scope as the old one, causing Identifier tl has already been declared errors from const/let re-declarations. Wrapping in an IIFE creates a new lexical scope. Also remove the old script element before inserting the new one. * fix(studio): return scriptText from mutation API, drop client-side HTML parsing The mutation API already has the extracted GSAP script text (newScript) after rewriting. Return it as scriptText in the response so applySoftReload receives the script directly instead of parsing HTML client-side. This avoids DOMParser compatibility issues across test environments and is more reliable than regex-based extraction. * fix(studio): align soft-reload script heuristic with server-side parser The client's findGsapScriptElement only matched gsap.timeline and __timelines. The server's extractGsapScriptBlock also matches .to( and .set(. Aligned the client heuristic to prevent silent fallback to full reload for compositions that use tl.to() without gsap.timeline in the same script. * fix(studio): address hf#1129 review — multi-script guard, scope docs - Return false (fallback to full reload) when multiple GSAP scripts exist in the document, since it's ambiguous which one to replace - Add docstring scoping the optimization to root-document scripts (template-wrapped sub-compositions fall back to full reload) - Add code comment explaining the IIFE scope constraint - Add test for the multi-script guard * fix(studio): align cache key filter with soft-reload script heuristic isGsapAnimationOnlyScript now also matches .to( and .set( patterns, matching findGsapScriptElement. Scripts using only tl.to() without gsap.timeline were excluded from soft-reload but still busted the shader cache on full-reload paths (undo, external changes). |

fix(studio): gsap panel bug bash — clamping, overlay, click cycling, visibility toggle (#1126)
* fix(studio): gsap panel bug bash — clamping, overlay, click cycling, visibility toggle - opacity/autoAlpha clamped to [0,1] (display 0–100%) — eliminates -30%/190% edits - `visibility` renders as a boolean toggle; only available to add in `set` tweens - ease curve section: use aspect-ratio container so control circles are not oval - MetricField scroll only fires when the input is focused (was triggering on scroll-over) - preview overlay clipped to its container (overflow-hidden) — no bleed into panels - `fromTo` method label updated to "From → To" (was "Animate", same as `to`) - repeated click at same position cycles through stacked/overlapping elements (#1124, #1125) resolveAllVisualDomEditTargets returns the full z-stack; subsequent same-spot clicks advance through all selectable layers at that coordinate - fallow-ignore-next-line complexity on pre-existing complex functions surfaced by branching from fix/gsap-fromto-panel rather than main Closes #1124, #1125 * fix(studio): address Vai+Rames follow-up notes on hf#1122 - extract buildTweenSummary to gsapAnimationHelpers.ts (now testable) - add tests for all buildTweenSummary branches including fromTo - extract requireAnimation/requireFromToAnimation helpers in files.ts, eliminating the parse→find→guard pattern repeated across three switch cases and removing the fallow-ignore-next-line complexity bypass - add 400 guard: add mutation with fromProperties on non-fromTo method now returns 400 instead of silently dropping fromProperties - add test for the 400 guard * fix(studio): buildTweenSummary formats percent props as 0-100% not 0-1 * fix(studio): show all .html files as compositions in sidebar The Comps sidebar only listed index.html and files under a compositions/ subdirectory. Any other .html file in the project root was invisible and could not be loaded as a composition preview. Broadened the filter in useFileManager and the activeCompPath guard in App.tsx to treat every .html file as a selectable composition. Also excluded App.tsx from the filesize pre-commit check — the file is already 652 lines (decomposition tracked in PR #724). * fix(studio): detect compositions by data-composition-id, not path convention The previous approach filtered compositions by path convention (index.html or compositions/ subdirectory). Any .html file outside that convention was invisible in the Comps sidebar. The server now scans each .html file for data-composition-id and returns a compositions[] field in the project API response. The client uses this server-provided list instead of filtering locally. This means any .html file that is a real HyperFrames composition shows up regardless of where it lives in the project tree. * fix(studio): rename Ask agent to Copy prompt to AI agent, show context preview Updated the property panel button label from "Ask agent" to "Copy prompt to AI agent". Updated the modal title to match. Added a collapsible "Context included in prompt" details section to the modal that shows the element metadata that will be included when copying. * fix(studio): wire contextPreview to agent modal Passes composition path, source file, selector, tag, and text content to the AskAgentModal so the context preview section is visible. * fix(core): seek timeline to current time after initial bind When bindRootTimelineIfAvailable captured a GSAP timeline for the first time, it paused it but never seeked to state.currentTime. This left fromTo tweens stuck at their immediateRender "from" state (e.g. opacity 0) even after the user scrubbed past the tween's end. The polling rebind path already seeked to previousTime — the initial bind was the only path that skipped it. * feat(core): add gsap_timeline_not_registered lint rule Warns when a composition creates gsap.timeline() but never registers it in window.__timelines. Without registration, the runtime cannot discover the timeline, and animations will not play during preview or render. Skips the warning for sub-compositions (template-based) which inherit the parent's timeline context. * fix(studio): address hf#1126 review feedback - Extract buildAgentContextPreview into domEditingAgentPrompt.ts and import it in App.tsx, removing the inline computation that pushed App.tsx past the 600-line CI gate - Switch isCompositionFile from sync readFileSync to async readFile with Promise.all, and use a regex test instead of string includes - Move PERCENT_PROPS from AnimationCard.tsx and gsapAnimationHelpers.ts into gsapAnimationConstants.ts (single source of truth) - Add regression test for the totalTime initial-bind seek fix in init.test.ts — verifies the captured timeline receives a totalTime call on initial bind * refactor(studio): extract App.tsx below 600 LOC, remove lefthook exemption Extracted inspector state, studio context construction, and drag overlay into useStudioContextValue.ts. Deduplicated block handler args via a shared blockCtx memo. App.tsx drops from 657 to 588 lines. Removed the App.tsx exemption from lefthook.yml — the file now passes the 600-line gate without special-casing. Added domEditing.ts barrel to fallowrc ignoreExports (re-exports not traceable by static analysis). |

feat: CLI observability + fix studio save failures on JS-created elements (#1091)
* feat(core): add probeElementInSource for source-existence checks
* feat(core): add probe-element endpoint for source-existence checks
* feat(studio): gate editing capabilities on source existence
* fix(studio): enrich save_failure telemetry with target details
* feat(studio): async selection resolution with source probe
Make `resolveDomEditSelection` async and wire a `probeSourceElement` call
into the selection path so elements generated by scripts (not present in the
source HTML) are detected early and have all edit capabilities disabled with
a clear reason message ("This element is generated by a script and cannot be
edited visually.").
Part A – core probe logic:
- `domEditingLayers.ts`: `resolveDomEditSelection` is now async; calls
`probeSourceElement` (POST /api/projects/:id/file-mutations/probe-element/:file)
when `projectId` is supplied and the element has a stable id/selector.
`existsInSource: false` flows into `resolveDomEditCapabilities`, which
disables all write capabilities with the appropriate reason.
- `domEditingLayers.ts`: `refreshDomEditSelection` promoted to async.
- `files.ts`: new `probe-element` route; extracted `resolveProjectPath`,
`resolveFileMutationContext`, `writeIfChanged`, and `parseMutationBody`
helpers to eliminate repeated boilerplate across remove/patch/probe handlers.
Part B – caller propagation (all eight consumer sites):
- `useDomSelection.ts`: `buildDomSelectionFromTarget`,
`resolveDomSelectionFromPreviewPoint`,
`buildDomSelectionForTimelineElement`, `handleTimelineElementSelect`,
`refreshDomEditSelectionFromPreview`, and
`refreshDomEditGroupSelectionsFromPreview` all made async; `projectId`
forwarded into `resolveDomEditSelection`.
- `useDomEditCommits.ts`, `useDomEditTextCommits.ts`: updated
`buildDomSelectionFromTarget` parameter type; added `await` at call sites.
- `useDomEditSession.ts`: inner `syncSelectionFromDocument` made async; fire
with `void` to satisfy the surrounding effect.
- `usePreviewInteraction.ts`: `handlePreviewCanvasMouseDown` and
`handlePreviewCanvasPointerMove` made async (React ignores handler return
values, so this is safe).
- `useStudioUrlState.ts`: deferred `buildDomSelectionFromTarget` call
converted to `.then()` chain with `void` prefix so the effect stays sync.
- `LayersPanel.tsx`: `seekToLayer`, `handleSelectLayer`, and
`handleLayerHover` made async.
- `DomEditOverlay.tsx` / `useDomEditOverlayGestures.ts`: `onCanvasPointerMove`
return type widened to `Promise<DomEditSelection | null>`; pointer-down
handler falls back to `hoverSelectionRef.current` (always populated by a
prior hover) instead of awaiting the async move callback inline.
Part C – test and tooling fixes:
- `lefthook.yml`: filesize hook shell loop explicitly skips `*.test.ts/tsx`
files as a guard against a lefthook v2.1.6 bug where `exclude` patterns are
not applied to `{staged_files}` in shell scripts.
- `domEditing.test.ts`: all `it()` blocks calling `resolveDomEditSelection`
made async with `await`.
- `DomEditOverlay.test.ts`: mock updated to return `Promise.resolve(selection)`
and `hoverSelection` pre-seeded so pointer-down test works with the new
hover-first path.
- `studioUrlState.test.ts`: `buildDomSelectionFromTarget` mocks wrapped in
`Promise.resolve()`; seek/selection hydration test made async with
`await act(async () => { await Promise.resolve(); })` to flush microtasks.
* feat(cli): add global error handlers for crash telemetry
Register process-level uncaughtException and unhandledRejection handlers
that fire trackCliError so unhandled crashes are captured in telemetry.
Add the trackCliError function to events.ts and re-export it from the
telemetry barrel.
* feat(cli): track per-command success/failure and duration
* test(core): add integration test for JS-created element probe scenario
* fix: address PR review feedback
- uncaughtException handler now calls process.exit(1) after flushing
- cli_command_result uses real exit code from process "exit" event
- drop stack_trace from cli_error (contains filesystem paths)
- skip source probe during hover — only probe on click/selection
- format .fallowrc.jsonc
* fix(cli): restore stack_trace in cli_error telemetry
* fix(cli): use captured module refs in exit handlers instead of dead import()

refactor(studio): split oversized files and raise line limit to 600
Split PlayerControls.tsx into focused sub-components (SeekBar, WorkAreaOverlay, MuteButton, LoopButton, FullscreenButton, ShortcutsPanel, SpeedMenu) and extracted seek bar drag/progress tracking into useSeekBarDrag hook. Split manualEditsDom.ts patch-builder functions into manualEditsDomPatches.ts with data-driven helpers to reduce duplication and complexity. Extracted per-type reapply helpers from reapplyPositionEditsAfterSeek and factored out identity-matrix check from stripGsapTranslateFromTransform.

fix(studio): use host composition dimensions for all added blocks
Blocks were using their own native dimensions (e.g. 1920x1080) instead of the host composition dimensions (e.g. 1280x720), causing them to overflow the viewport and break the layout. The block's iframe scales its content to fit the container, so using host dimensions is correct. |

fix(studio): read z-index from live iframe DOM, rename Layer to Z-index
Replace fragile regex z-index parsing with getComputedStyle on the preview iframe elements — the same source of truth the inspector uses. Rename "Layer" to "Z-index" in the design panel for clarity. |

feat(studio): improve blocks panel UX
- Rename "Blocks" tab to "Catalog" - Replace fullscreen hover popup with inline preview in main area - Fix z-index: newly added blocks/components use max existing z-index + 1 instead of element count, ensuring they appear on top |

feat(studio): preserve drop position when dropping blocks onto preview
Blocks dragged from the Blocks panel and dropped onto the composition preview now land at the position where they were dropped, instead of always being placed at (0, 0). The preview viewport converts screen coordinates to composition space using the stage element's bounding rect, accounting for zoom and pan. A visual drop indicator (dashed border overlay) appears while dragging over the preview. |

fix(studio): server-side DOM patching, render CSS scoping, and resilience
Root-cause fix for edits being wiped after refresh: the studio's
inspector edits were patched client-side via regex matching in
sourcePatcher.ts, which silently failed for many compositions ("Unable
to patch" toast). Replaced with a server-side patch-element API endpoint
using linkedom for proper DOM parsing via querySelector.
Also fixes the WYSIWYG render bug where sub-composition CSS was not
applied. The CSS scoping generated descendant selectors when both
attributes coexist on the same host element. Fixed to use compound
selectors for the authored root.
Edit persistence:
- New POST /file-mutations/patch-element endpoint using linkedom
- persistDomEditOperations calls server instead of client regex
- 15 tests covering all patch operation types
Render CSS scoping:
- Compound selector for authored root on host element
- Regression test: wysiwyg-subcomp-css (baseline pending Docker)
- 3 unit tests + 1 integration test
GSAP CDN fallback:
- Preview: error-handler catches gsap 404 and loads from CDN
- Producer: rewrites missing local gsap paths to CDN before compile
Studio resilience:
- Error boundary with recoverable UI
- Lazy mediabunny import prevents crash cascade
- Hash routing listens for hashchange events
- Sub-composition duration reads data-hf-authored-duration fallback
- Save debounce 600ms to requestAnimationFrame
Observability:
- PostHog telemetry for crashes, save failures, tab switches, playback,
toolbar actions, navigation, and render starts

fix(studio): address PR review — add tests, strip GSAP transform for rotation, remove dead exports
Addresses review feedback from Rames and Vai: 1. Add 7 new tests for createStudioPositionSeekReapplyScript: box-size reapplication, GSAP translate stripping (identity removal, scale+translate preservation, transform:none no-op), and rotation- only elements with GSAP-baked translate. 2. Add pinning test for the PiP-over-sub-composition selection bug: elementsFromPoint returns [pipVideo, subCompRoot, sfChromeImg] as siblings — assert the topmost (pipVideo) wins. 3. Apply stripGsapTranslateFromTransform to rotation-only elements too, not just path-offset elements. A rotation-only element with a GSAP-animated translate would have its position clobbered. 4. Remove dead exports: getPreviewLocalPointer, buildRasterClickSelectionContext, getPreviewPlayer, seekStudioPreview, PreviewPlayerCompat, PreviewLocalPointer from studioPreviewHelpers.ts. Unexport resolvePreviewLocalPointer. |

fix(studio): stop injecting inline z-index on all clips during timeline edits (#959)
## Summary - Remove the z-index injection loops from timeline move, delete, and asset-drop commit paths — only timing/track attributes are now patched on the affected clip, leaving all other clips untouched - Fix `patchInlineStyleInTag` to handle self-closing void elements (`<img />`, `<audio />`) — the old code produced malformed `<img ... / style="z-index: 7">` output - Delete the now-unused `buildTrackZIndexMap` helper and its tests ## Root cause Three timeline operations (`handleTimelineElementMove`, `handleTimelineElementDelete`, `handleTimelineAssetDrop`) looped over every clip in the file on each commit and injected `style="z-index: N"` derived from an inverted `data-track-index` mapping via `buildTrackZIndexMap`. This overrode the author's CSS z-index — contradicting the documented contract that `data-track-index` does not affect visual layering — and persisted the corruption in the source HTML. ## Test plan - [x] Reproduction test covering old bug behavior (inline z-index injection on all clips, inverted layering) - [x] Verification tests confirming move/delete only patches the affected clip's timing attributes - [x] Void element tests confirming `<img ... style="..." />` output (not `<img ... / style="...">`) - [x] End-to-end browser test: opened Studio, dragged badge clip in timeline via CDP, verified only `data-start` changed on the dragged clip with zero inline z-index injections - [x] Full test suite: 585 tests pass (54 files) - [x] Build, lint, format, typecheck all green Closes #958 |

fix(studio): stop injecting inline z-index on all clips during timeline edits
Timeline move, delete, and asset-drop operations were looping over every clip in the file and writing style="z-index: N" derived from an inverted data-track-index mapping. This silently overrode the author's CSS z-index — contradicting the documented contract that data-track-index does not affect visual layering — and persisted the corruption in the source HTML. Remove the z-index injection loops from all three timeline commit paths. Move and delete now only patch timing/track attributes on the affected clip. Asset drop still sets z-index on the newly created element via the generated HTML, without touching existing clips. Delete the now-unused buildTrackZIndexMap helper. Also fix patchInlineStyleInTag to handle self-closing void elements: the old code produced malformed `<img ... / style="z-index: 7">` because it didn't account for the trailing `/` before appending the style attribute. Closes #958 |

refactor: delete orphan declarations flagged by fallow (#949)
* ci: run fallow audit in lefthook pre-commit Mirrors the same `fallow audit --base ... --fail-on-issues` check that runs in CI, but locally against HEAD so issues surface at commit time instead of after the push round-trip. Scoped to `packages/**` source files via the glob — non-code edits (README, docs, top-level configs) skip the hook entirely. Measured locally: ~5s in parallel with the existing lint/format/typecheck checks. Doesn't extend wall-clock time because typecheck (~11s) is the long pole, and lefthook runs commands in parallel. The default `--gate new-only` means inherited findings don't block the commit — same gate behavior as CI, so local pre-commit and PR audit agree. * refactor: delete orphan declarations flagged by fallow After fallow's auto-fix de-exports unused symbols, oxlint surfaces them as no-unused-vars. This PR deletes those orphan declarations outright. Biggest cleanup: studio/src/icons/SystemIcons.tsx shrinks from 132 to 57 lines — 33 unused icon wrappers and their phosphor-icon imports deleted. Other deletions across 14 more files covering paired getter/setters, helper functions, dead env constants, internal components with no callers, and cascading unused imports. Cascade-causing files held back for follow-up PRs: renderOrchestrator barrel of captureCost re-exports, telemetry/portUtils/remote barrels, Button.tsx + ui/index.ts (would orphan whole file), studioMotion type re-exports. Test plan: typecheck clean across 8 packages, oxlint + oxfmt clean, fallow audit exit 0 (remaining findings inherited), cli + studio vitest suites pass. |

feat(studio): full Blocks panel — browse, search, add, drag-and-drop registry items
Adds a Blocks tab to the Studio left sidebar with the full 78-item registry
catalog (58 blocks + 20 components). Users can browse by category, search by
title/description, preview CDN-hosted poster thumbnails with video-on-hover,
and install items on-demand with one click or drag-to-timeline.
Core changes:
- BlockCategory type + resolveBlockCategory() for 7 categories (Captions, VFX,
Transitions, Effects, Social, Data, Scenes)
- Registry API routes: GET /api/registry/blocks (catalog) + POST install
- StudioApiAdapter extended with listRegistryCatalog + installRegistryBlock
- Vite adapter reads from disk; CLI adapter fetches from GitHub (24h cache)
- BlockParam interface + params on 6 blocks for future parameter controls
Studio UI:
- 4th sidebar tab "Blocks" with responsive grid, category pills, search bar
- BlockCard: CDN poster thumbnail, video autoplay on hover, duration + WebGL badges
- On-demand install: blocks append as sub-compositions on timeline; components
overlay at start=0 spanning full duration with transparent background patching
- TIMELINE_BLOCK_MIME drag-and-drop to timeline
- BlockParamsPanel (Phase 3 scaffold) auto-opens for parameterized blocks
Registry manifests:
- All 58 blocks backfilled with preview: { video, poster } CDN URLs
- All 20 components normalized to object format + poster URLs added
- 6 blocks annotated with params (Liquid Glass/Background, Portal, Chart,
Logo Outro, Magnetic)
- flowchart-vertical preview generated and uploaded to CDN

refactor: drop unused exports detected by fallow auto-fix
Run `fallow fix --auto-fixable` to remove `export` keywords from symbols fallow's reachability analysis identifies as unused. Keeps only the cases where the symbol is still referenced internally in its own file (so removing `export` doesn't surface a new oxlint `no-unused-vars` error). Result: fallow dead-code findings drop from 276 → 208 (68 fewer unused exports), with no behavior change — each symbol is still defined and used exactly the same way within its file. Reverted ~20 files where fallow's auto-fix would have created cascading "declared but never used" lint errors — those are cases where the symbol isn't used at all, and properly cleaning them up means deleting the declaration, not just dropping `export`. Better to land that as a separate, narrower PR rather than mixing it into a mechanical de-export. Also reverted four false positives where fallow missed real consumers: - `captureCost.ts` (renderOrchestrator has two separate import blocks from the same module; fallow only saw the first) - `propertyPanelHelpers.ts`, `domEditingLayers.ts` (real internal uses fallow's reachability missed) - `render.ts` (functions imported via `await import()` dynamic import, which fallow's static analysis doesn't follow) Test plan: bun run --filter '*' typecheck (clean), oxlint + oxfmt clean, cli/core/studio/engine vitest suites pass (335 + 917 + 576 + 605 tests). |

feat(studio): add media properties panel for video/audio elements
Adds a new Media section to the Design panel that appears when a <video> or <audio> element is selected. Controls include volume (slider), playback rate, media start offset, loop/muted toggles, and for video: object-fit, object-position, poster, and has-audio-track toggle. Extends the source patcher with an "html-attribute" operation type for native HTML attributes (loop, muted, poster) that don't use the data- prefix. Adds coalesceKey to attribute commits so rapid slider/scrub edits merge into a single undo entry. |

feat(studio): add Ctrl+C/V/X copy/paste for timeline clips and DOM elements (#894)
* feat(studio): add clipboard payload types and ID deduplication * feat(studio): add Ctrl+C/V/X copy/paste for timeline clips and DOM elements * fix(studio): use duck-typing for cross-frame element access in clipboard Elements from the preview iframe are from a different window context, so `el instanceof HTMLElement` always returns false. Use `"outerHTML" in el` instead to correctly detect elements across frame boundaries. * fix(studio): preserve playhead position after paste reloadPreview() used location.reload() which bypassed the NLELayout saveSeekPosition effect, causing the playhead to reset to 0:00 after paste. Switch to setRefreshKey which triggers the effect and restores the seek position after the iframe reloads. * fix(studio): paste DOM elements as siblings, not at composition root DOM element paste was inserting at the composition root, losing the parent context that provides CSS styles and positioning. Now stores the origin selector on copy and inserts the paste as a sibling immediately after the original element, preserving style inheritance. Falls back to root insertion if the selector can't be matched. * fix(studio): address review — deduplicateIds, native copy, altKey guard - deduplicateIds regex used \b which matched data-composition-id, data-clip-id, etc. Switch to lookbehind (?<=\s) so only standalone id="..." attributes are rewritten. Add test pinning this. - Ctrl+C no longer calls preventDefault() before confirming there's a selected element. Native browser copy (text selections outside inputs) is preserved when nothing is selected in the Studio. - Add !event.altKey guard on C/V/X to avoid intercepting Cmd+Alt+V (paste-as-plain-text) and similar OS gestures. - Remove no-op .replace(/"/g, '"') flagged by CodeQL. * fix(studio): address review round 2 — Cmd+X guard, data-start scope, revert drive-by - Cmd+X now pre-checks selection state before preventDefault, mirroring the Cmd+C fix. Native cut preserved when nothing is selected. - handleCut returns Promise<boolean> so the caller can gate on it. - data-start rewrite scoped to the outermost opening tag only, so nested clip timing is preserved on paste. - Removed system clipboard write (cross-tab paste unsupported, in-memory ref is the only read path). - Reverted the reloadPreview drive-by (setRefreshKey→location.reload); the perf branch (#895) handles this properly via refreshPlayer(). |

fix(studio): fix seek after code edit, improve scrub perf, add click-to-source (#881)
* feat(studio): html-backed motion panel — persist GSAP motion to element attributes Re-architects the motion panel to store GSAP motion data as a JSON data attribute (data-hf-studio-motion) on each element instead of a .hyperframes/studio-motion.json sidecar file. Follows the same pattern as position/resize/rotation edits: write to DOM, build patches, persist to HTML source via commitPositionPatchToHtml. Render pipeline: the studioPositionSeekReapplyRuntime now queries [data-hf-studio-motion] elements after each seek, parses their JSON, builds a GSAP timeline, and seeks it to the current frame time. Studio preview: motion reapply is integrated into the manual edits seek hook (reapplyPositionEditsAfterSeek). useManifestPersistence is slimmed to only handle save queue and seek hooks. * fix(studio): address PR review — html-escape attrs, cache timeline, migrate sidecar, add tests Blocker: JSON attribute values are now HTML-entity-escaped before being written into source HTML. Read-back unescapes automatically. Perf: motion timeline is cached between seeks at render — only rebuilt when the concatenated JSON key changes, not on every frame. Migration: on mount, empties legacy .hyperframes/studio-motion.json so the legacy render script no-ops. Tests: 46 new tests for motion read/write/clear round-trips, JSON attribute escaping, and source patcher entity handling. Nits: removed unused activeCompositionPath param; tightened htmlCompiler attribute substring check. * fix(studio): fix seek after code edit, improve scrub performance, add click-to-source Three issues addressed: 1. **Seek breaks after code edit**: During crossfade refreshes the retiring Player's cleanup unconditionally nulled `iframeRef.current`, clobbering the reference the new Player had already assigned. Guard the cleanup to only clear the ref when it still points to the retiring Player's own iframe. 2. **Scrubber/timeline drag jank**: Every pointermove during a drag called the full seek pipeline (adapter.seek + setCurrentTime + React re-render cascade). RAF-throttle the expensive onSeek call during drags while keeping slider and playhead visuals updated on every pointer event for instant feedback. 3. **Click-to-source**: Clicking an element in the preview now switches to the Code tab, opens the element's source file, and scrolls the editor to the element's opening tag. Uses the existing `findTagByTarget` source patcher to locate the element by id/selector in the HTML source. * fix(studio): address PR review — gate click-to-source, fix fetch race, guard refs - Gate click-to-source on Alt/Option+click so it doesn't steal the Code tab on every preview click, conflicting with select-to-inspect workflow - Fix fetch race in openSourceForSelection: AbortController cancels the previous in-flight fetch, monotonic request ID prevents stale responses from applying the wrong file/offset - Guard the callback-ref branch in Player cleanup (no-op — can't read back from a callback ref to check identity, and the path is unreachable today since the ref is always a MutableRefObject) - Import SidebarTab type instead of duplicating the literal inline |
