Both writes share one coalesce key (zReorderCoalesceKey) and fold into ONE undo entry (test proves it over the real history reducer). The mirror never triggers the lane->z stacking sync, so it cannot fight the z values the action just set. - timelineZOverride.ts + TimelineClip badge: clips whose paint order contradicts lane order among temporally-overlapping same-context visual neighbors (laneIsAbove XOR paintsAbove, the stacking-sync predicates) show a 'z' badge — authored z overrides are surfaced instead of silently disagreeing with the timeline. - Timeline.tsx track derivations extracted to useTimelineTrackDerivations (600-line cap). * fix(studio): fold mirrored z-order gestures into one undo entry across slow persists Live verification caught the z write and the mirrored lane write splitting into two undo entries: the mirror runs after the z persist's server round trip, which exceeds editHistory's default 300ms coalesce window under real latency (the unit test's deterministic clock sat inside it). zReorderCoalesceKey now mints a per-gesture-unique key (monotonic seq, the laneChangeGestureSeq precedent) and both records carry coalesceMs Infinity — distinct gestures can never merge, and one gesture always folds regardless of write latency. coalesceMs threaded through the persist chain alongside coalesceKey. Also hardens the existing lane-drag move->z fold, which had the same latent split. Fold test now simulates a 400ms gap (failed before the fix, passes after); a two-separate-gestures test asserts two entries. * feat(studio): flashless lane mirror, z-order menu icons, close-gap track menu - Track-only batch moves (the z-mirror's lane hop and the insert renumber) skip the GSAP fallback round-trip and the preview reload entirely — the renderer never reads data-track-index, and the live DOM patch + optimistic store update cover the UI. Mixed batches keep current behavior. Kills the canvas blink on mirrored Bring/Send actions (live-verified: an iframe-scoped marker survives the whole gesture). - The four z-order menu items get 16px stroke icons (single layer diamond + directional arrow for Forward/Backward; pierced two-layer stack for Front/Back); labels unchanged — they are the industry-standard names. - New track context menu on empty lane space: 'Close gap' (shifts the next clip and every clip after it on that lane left by the clicked gap's width; leading gaps count, so a single clip with empty space before it compacts to 0) and 'Close all gaps' (whole lane contiguous from 0). Pure gap math in timelineGaps.ts; persists through the drag path's atomic batch move (one undo per action); refuses when a clip that must shift is locked; items disable when there is nothing to close. * fix(studio): rebind-only preview sync for unmutated timing edits, classical z-menu order Timing edits that rewrote NO GSAP positions (gap closes and moves of selector-addressed caption clips, zero-delta batches, comps without a rewritable script) full-reloaded the preview — and the rerun-current-scripts attempt was wrong for real compositions: re-executing init-style scripts (three.js scenes, caption engines) is exactly the unsafe case, verified live by doubled init warnings and a fallback reload anyway. The correct observation: when mutated === false the existing __timelines are still valid — only the runtime's clip visibility windows are stale, and the live DOM timing attributes were already patched. So the no-mutation path now runs applySoftReloadFinalization only (seek + __hfForceTimelineRebind + manual-edits reapply), extracted from the soft-reload machinery — zero script execution. This also un-blinks comps with no GSAP script at all, which previously always remounted. Rewritten-script soft reloads, cannot-soft-reload, otherFileChanged, and mutation failures keep their existing behavior. gsapSoftReload's undo/redo restore section moved verbatim to gsapUndoRestore.ts for the 600-line cap. Also: z-order menu items reordered to the classical arrangement (Bring to Front, Bring Forward, Send Backward, Send to Back). Live-verified on a three.js-heavy composition: Close-all-gaps shifted 4 caption clips with correct cumulative amounts, the preview iframe was never remounted (marker survived), and one undo reverted everything. * fix(studio): bound forward/backward mirror to a one-element step User-specified semantic: Bring Forward / Send Backward move the clip past EXACTLY ONE element. The mirror's lane target is now bounded by the next temporally-overlapping element beyond the crossed neighbor: a free lane strictly between the two is taken (closest to the neighbor), and when they are back-to-back a new track is inserted immediately beyond the crossed element — never past the second one. Previously the resolver took the closest free lane anywhere beyond the neighbor, which could carry the track past a second element while the z action only stepped past one — a track/paint contradiction our own zOverride badge would flag. Front/back keep whole-set semantics (past everything; back stays above the audio zone). End-to-end test pins the 3-stacked case through commitZMirrorLaneMove to the persisted renumbered tracks. * feat(studio): permanent gap-menu rows with hover and click-select gap highlights - TrackGapContextMenu always renders both rows; an inapplicable action dims with a tooltip ("No gap here" / lock reason / "No gaps on this track") instead of vanishing into a one-item menu. Width badge only when a gap exists under the pointer. - Hovering an ACTIONABLE row highlights the strip(s) it would close in the timeline: the single gap for Close gap, every current gap (leading included) for Close all gaps. New resolveAllGapIntervals in timelineGaps.ts reports present-state intervals (epsilon-tolerant, overlap-safe), distinct from resolveAllTrackGaps' post-compaction starts. - Click-selecting a single clip paints a quieter tint over its lane's gaps (suppressed for marquee multi-selection and during drags; the gap-menu hover wins on its own lane). Derivation lives in useTimelineGapHighlights with the pure buildTimelineGapStrips exported and unit-tested. - Strips render in TimelineCanvas with the drop-placeholder geometry (row top + clip inset), dashed accent for hover, faint tint for selection. - Timeline.tsx stayed under the 600-line cap by extracting the scroll-viewport plumbing (ResizeObserver width + shortcut-hint sync) into useTimelineScrollViewport, behavior unchanged. * feat(studio): stronger capcut-style timeline zoom steps One button press / pinch gesture now moves the zoom meaningfully: step factors 1.25x/0.8x -> 1.5x/(2/3) (kept reciprocal so in+out round-trips) and pinch sensitivity 0.0035 -> 0.007. Addresses "zooming several times to get anywhere" feedback; cursor anchoring unchanged. * feat(studio): three-way z sync — layers drags mirror timeline lanes, panel tracks live z edits Completes the layers/canvas/timeline sync triangle: the Layers panel was the one surface whose reorders never reached the timeline, and the one that went stale when the other two wrote z flashlessly. - Layers drag -> minimal z + equal-jump lane mirror. handleReorder now uses the canvas menu's realization core via resolveZOrderReposition (one between-z write when a strict gap exists, band-safe scoped renumber otherwise) instead of computeReorderZValues' all-sibling stamp — that helper is deleted, completing the #2347 unification follow-up. The drop then mirrors into a timeline lane move through the same machinery as the canvas menu (new resolveRepositionLaneMove: the clip lands on a free lane strictly between its NEW paint neighbors' lanes — nearest clip siblings in the desired render order, decorations skipped — else a track insert at that boundary; audio zone never crossed). Both writes share one per-gesture zReorderCoalesceKey with an unbounded fold window, so a drag is exactly ONE undo entry; useCanvasZOrderTimelineMirror's plumbing is factored into useMirrorLaneMoveCommit and reused by the new useLayerReorderTimelineMirror. A same-slot drop is a hard no-op (new order-equality guard in resolveZOrderReposition). - Panel staleness fix: flashless z commits (skipReload) reload nothing and bump no refreshKey, so the panel's z-sorted order went stale while paused. handleDomZIndexReorderCommit now bumps a store zEditVersion on apply AND rollback; the panel re-collects on it. Verified live: the panel re-sorts the instant a drag commits and again on undo. - Layer click reveal (useLayerRevealOverride): clicking a layer that stays hidden at the current frame (animation-parked opacity, non-clip display/visibility hides, hidden ancestors) temporarily forces the chain visible with live inline styles — exact priors restored on deselect, on another reveal, on play, and on unmount; never persisted (file diff == 0 verified live). Clips keep the existing seek-into-window behavior; the override applies on a short defer so a seek-revealed clip needs none. - layerOrdering's unused hasExplicitZIndex probe (zero callers) removed. Live-verified on a bed copy: a 2-position layers drag wrote exactly one element (z 6->23 + data-track-index 15->2), the timeline lane moved without a reload, and a single Cmd+Z restored the file byte-identically. * feat(studio): full-track selection highlight, borderless gap hover strips - Click-selecting a clip now lights the WHOLE lane minus its clips — leading gap, inter-clip gaps, and the open space after the last clip to the rendered end (new resolveLaneEmptyIntervals; displayDuration threaded into the strip derivation). Still click-only: any drag/resize suppresses the strips, and a marquee multi-select never shows them. - The gap-menu hover strips drop the dashed border (user feedback) — fill only, nudged to 0.18 alpha to keep the same visual weight. * feat(studio): selected layer paints on top via a reader-transparent z lift Clicking a layer in the Layers tab now shows the element as if it were at the very top of the stack while selected — whatever its authored z or panel position — extending the reveal override (which already forced hidden chains visible) with a temporary inline z lift: - liftElementToTop parks the TRUE effective z in data-hf-reveal-prior-z and writes a far-top inline z; a static element gets a layout-preserving position:relative with its prior parked in data-hf-reveal-prior-pos. Only the RENDERER sees the lift: all three studio z readers (readTimelineElementZIndex, getElementZIndex, readEffectiveZIndex) return the parked prior while the attribute is present, so the canvas z-menu, the zOverride badge, the lane mirror, the stacking sync, and the panel sort keep reasoning on the element's real z. - Strictly ephemeral: exact priors restored on deselect / another reveal / play / unmount, each property only while it still holds the value the override wrote (a later real edit is never clobbered). File diff == 0 verified live across a full lift/restore cycle. - A z-reorder commit CONSUMES an active lift (handleDomZIndexReorderCommit reads the parked position for its persist-position:relative static check, then drops the attributes) — the committed z becomes the truth and the later restore is a guarded no-op. * fix(studio): flashless undo/redo — three full-reload causes in the soft-restore path Cmd+Z blinked the canvas on essentially every undo. Three independent causes in applyUndoRestoreToPreview, each sufficient on its own: 1. Master-view path gate: activeCompPath is NULL at the master view, so the 'paths[0] === activeCompPath' eligibility check could never match the index.html restore and every default-view undo full-reloaded at the first gate. Normalized to the codebase-wide 'activeCompPath ?? "index.html"'. 2. Nested identity innerHTML check: the diff compared each identified element's innerHTML, but the composition root wraps every clip — any child change re-detected at the root rejected the restore. Change detection now compares only each element's OWN attribute surface; structure/text integrity is still guaranteed by the normalize-residual whole-doc pass (text nodes, added/removed elements, and un-identified attrs all remain after normalization and force the full reload). 3. id-only identity: elements addressed by data-hf-id / selector (no DOM id) fell outside the diff entirely. Identity is now id OR data-hf-id, with the live sync resolving either. Also stop re-running an UNCHANGED GSAP script: attribute-only restores (z, lane, timing, style — the overwhelmingly common undo) now use the rebind-only finalization (seek + __hfForceTimelineRebind + manual reapply, zero script execution — the same path as flashless timing edits), instead of tearing down and rebuilding live timelines or full-reloading when the script can't be scoped. A restore whose script text genuinely changed still re-runs it via applySoftReload, and structural restores (split/delete) still full-reload. Live-verified on the bed (iframe marker): gap-close undo AND redo both keep the iframe mounted, live DOM lands on the restored values, disk restored byte-identically. * feat(studio): left breathing pad before t=0, double zoom sensitivity again TRACKS_LEFT_PAD (48px) — the horizontal sibling of TRACKS_TOP_PAD: empty lane surface between the sticky gutter and the ruler's 00:00 / the first clips, scrolling WITH the content. - The lanes and the ruler realize it as a plain flow spacer between the sticky gutter cell and the time-mapped content div, so every content-relative computation (clip left = t*pps, beat lines, lane-menu time, clip drag deltas) is untouched by construction. - Canvas-space overlays shift by the pad: playhead (getTimelinePlayheadLeft), gap strips, drop placeholder, snap guide, range highlight, marquee clip rects, beat SVG; the insert line spans the pad. - Every pointer->time inverse subtracts it symmetrically: seekFromX, razor, range/marquee anchors, asset drops, and the zoom-anchor gutter basis; fit pps and the display width account for the consumed viewport width. - Live-verified: t=0 clip edge, the 00:00 tick, and the playhead line center all sit at GUTTER + TRACKS_LEFT_PAD, and a ruler click lands the playhead center exactly under the pointer. Also doubles the timeline zoom sensitivity again (user feedback after feel-testing the first bump): button steps 1.5x/(2/3) -> 2x/0.5, pinch 0.007 -> 0.014. * fix(studio): left pad renders as true empty space, not lane surface The pad before t=0 inherited each row's background and bottom border from the row wrapper, so it read as track lanes. Lane visuals now live on the cells: the sticky gutter keeps its own separator (header column stays delineated), the time-mapped content div carries the row background + separator, and the pad spacer stays transparent — bare shell background, no lines. The new-track insertion line also starts at the pad's end instead of crossing it. * fix(studio): no vertical line in the ruler band before 00:00 The ruler corner's right border drew the header-boundary line through the ruler strip, so the band didn't read as starting at 00:00. Dropped it — the boundary line belongs to the track rows below; the ruler stays completely clean from the panel edge to the first tick, matching the empty left pad. * refactor(studio): remove the timeline z-override badge User decision: the "z" chip on clips never earned its place — dropped entirely (timelineZOverride.ts + test deleted, TimelineClip badge rendering and the zOverrideKeys derivation/threading removed). This also eliminates the review's D2 finding at the root: the badge's cross-document comparison (stackingContextId ?? null collides across source files in the expanded view) produced false positives, and there is no longer a detector to mis-fire. overlapsInTime/paintsAbove lose their export (the badge was their only external consumer); the paint-order predicate itself is unchanged. * fix(studio): collision-free expanded child lanes and host-window gap floors Review findings D1 (blocker) and 4. - D1: buildChildElements assigned expanded children synthetic display rows as `host.track + index` — integers that can EQUAL a real clip's lane in another file (host on 0 with two children puts child #2 on 1). Lane grouping merges purely by track number, so the collision fused clips from different source files into one display lane, and lane-scoped actions (the gap menu) then batch-persisted a foreign file's clip. Children now take FRACTIONS strictly between the host's lane and the next integer — structurally unable to collide with any normalized lane, while still rendering as ordered rows under the host. Regression test pins the reviewer's exact two-file scenario. - Finding 4: gap math compacted toward absolute 0, but an expanded child's display time is host-anchored — close/compact could drag it before its host window and persist a wrong (even negative) local time. All gap functions now take a lane FLOOR (laneGapFloor: 0 for ordinary lanes, the children's expandedParentStart for child lanes — single-origin per lane post-D1), threaded through the menu model, hover highlights, selected-lane strips, and both commits. Close-gap shifts clamp at the gap's own left edge. * fix(studio): scope mirror references, insert writes, and crossed-neighbor identity Review findings 1, 2, and 3. - Finding 1: buildTrackInsertEdits normalized the FULL display set and persisted every shifted clip — writing host-lane numbers into OTHER composition files when expanded children were showing. The renumber write set is now the edited element's own source file (the sanctioned multi-write converges one FILE to lane space, never neighbors' files); foreign clips keep their authored tracks and re-derive display lanes. The locked-clip refusal scopes the same way. Expanded-origin elements refuse the insert outright (a new lane is a host-space renumber, meaningless in the child's file), and the mirrors restrict an expanded child's lane candidates to its own siblings' lanes — a sub-comp child still mirrors WITHIN its sub-comp (persisting the sibling's authored track) but can never land on a host lane with no same-file occupant. authoredTrackForLane's offset fallback rounds: fractional synthetic rows must never leak fractions into data-track-index. - Finding 2: the mirror comparison sets required only sameSourceFile, but a file can contain several CSS stacking contexts and leaf z is only comparable within one. Both resolvers now scope by samePaintScope — same source file AND same stackingContextId (the file check also stops null root contexts of different files from comparing equal in the expanded view). - Finding 3: the crossed-neighbor key was derived without selectorIndex, so duplicate class selectors (.sub) resolved to occurrence 0 — a different clip. The key now carries getSelectorIndex, matching how z-reorder entries derive theirs. * fix(studio): z-to-lane gestures are one serialized transaction gated on durable persists Review findings 5 and 7. - Finding 5: commitDomEditPatchBatches resolved successfully even when the server matched NO patch target — the z write never reached disk (the preview reloads to reconverge) yet the lane mirror still ran, desyncing track order from what actually paints. The commit now resolves a durability report ({allMatched, changed}; the save queue and commit types are generic over the result), and the mirror phase is skipped on allMatched === false. - Finding 7: the z persist rides the DOM-edit save queue while the lane move rides the timeline/SDK path — two queues, so a second rapid gesture's z write could land BETWEEN the first gesture's z and lane phases. Every z-to-lane gesture (canvas z-order menu AND Layers-panel drag) now runs through runZLaneGesture: a single module-level tail that serializes the COMPLETE two-phase transaction, with unit tests for ordering, the durability gate, and queue resilience to failed gestures. The timeline lane-drag's inverse (move-then-z-sync) shares its phases' await ordering already; cross-gesture serialization for that path is noted as follow-up. - LayersPanel's pure sort helpers moved to layersPanelSort.ts (600-line cap). * fix(studio): multi-clip GSAP batch mutations roll back on late failure Review finding 6. finishGroupTimingGsapFallback mutates files sequentially per clip; a late per-clip failure left the earlier rewrites on disk with no aggregate history entry — unreachable by undo. foldGsapMutationIntoHistory already snapshots every touched path before mutating; on a mutation failure it now restores each path whose disk content changed (all-or-nothing batch), reports restore errors without masking the original failure, and rethrows. Regression test drives a two-clip batch whose second rewrite fails and asserts the first clip's write is restored byte-identically. * fix(studio): scope mirror inserts to their lane zone * fix(studio): unify source-scoped clip identity * fix(studio): isolate track insert topology * fix(studio): harden timeline paint synchronization --------- Co-authored-by: Miguel Angel Simon Sierra <miguel.sierra@heygen.com>	2026-07-14 14:31:58 -04:00
Miguel Ángelandukimsanov	df29fa7a5e	feat(studio): revamps Studio + improves code quality (#2291) ... * feat(studio): glue API coexistence layer for the NLE swap What: extends 21 glue files so the OLD timeline/canvas engine and the NEW NLE components type-check side by side: playerStore (multi-select setters, zoom pin, snap toggle, non-reactive scale scratch), drag-state types gain optional NLE fields, timelineLayout/timelineAssetDrop/timelineEditingHelpers/ timelineEditing/timelineElementHelpers/studioHelpers/assetHelpers gain the NLE exports, DomEditOverlay + gestures + AssetContextMenu + Timeline props gain optional callbacks/params, contexts gain *Optional hooks, and TimelineEditCallbacks.onMoveElements becomes a bivariant method accepting both engines' change shapes. patchDocumentRootDuration's test rides along. Why: this is the keystone that dissolves the old "welded glue" problem — every symbol the NLE components need is ADDED next to what the old engine still uses, so the engine components and the swaps can land as separate reviewable PRs. How: 15 authored intermediate files (main content + additive symbols; no behavior changes — new fields optional, new callbacks unused until wired) plus 6 files whose final content is already purely additive. New exports without consumers yet carry TEMP(studio-dnd) ignoreExports entries, removed by the app-shell swap. Test plan: tsc --noEmit in studio + studio-server (verifies BOTH engines compile); bunx vitest run (full suite green incl. the 6 new patchDocumentRootDuration tests); fallow audit clean. * feat(studio): timeline interaction hooks and lanes component (unwired) What: the timeline-side wiring layer, unwired: TimelineLanes (the lane renderer driving drag/resize/marquee), timelineMarquee (+tests), useTimelineStackingSync, useTimelineGeometry, useTimelineEditPinning, useTimelineEditingDrops. Why: everything between the pure drag math and <Timeline> itself; the timeline-glue swap PR then only rewires Timeline/TimelineCanvas onto these. How: new files, tsc-clean against the coexistence layer. Unwired components carry TEMP(studio-dnd) entry registrations, removed at the app-shell swap. Test plan: bunx vitest run timelineMarquee.test.ts; tsc --noEmit; fallow audit clean. * feat(studio): NLE shell assembly (unwired) What: EditorShell (the full editor layout replacing NLELayout + StudioPreviewArea), TimelinePane (timeline host with sub-comp rebasing) and useTimelineEditCallbacks (the callback bag bridging store edits to the timeline), all unwired. Why: the shell that App swaps to in the final step; reviewing it standalone keeps that swap PR small. How: new files against the coexistence layer; TEMP(studio-dnd) entries until App mounts EditorShell in the app-shell swap. Test plan: tsc --noEmit; bunx vitest run (suite unchanged); fallow audit clean. * feat(studio): timeline glue swap — Timeline/TimelineCanvas onto the NLE engine What: flips the timeline glue to its final form (23 files): Timeline and TimelineCanvas rebuilt on TimelineLanes/TimelineOverlays, useTimelineClipDrag drives preview/commit through the new drag engine, range selection goes multi-select, playback loop moves to useTimelinePlayerLoop. Deletes the 9 old-engine files this orphans (group drag, marquee selection, snap targets, layer gutter, selection overlays + their suites) — each is compile- or gate-forced by this swap, verified by probe. Why: second swap step; timeline-only, canvas and App untouched. How: modified files to final content + forced deletions. playerStore/timelineEditing/timelineCallbacks stay at their coexistence form until the app swap (the old App still runs on them). Test plan: tsc --noEmit; bunx vitest run (full suite); fallow audit clean. * feat(studio): clip thumbnail modules What: ImageThumbnail (+tests) and thumbnailUtils (+tests) — frame decode with SVG/AVIF format fallbacks and rounded-corner clipping — plus VideoThumbnail updates. Why: the decode layer for timeline clip thumbnails, ahead of the visual refresh that renders them. How: new modules + one modified file; purely presentational. Test plan: bunx vitest run on both test files; tsc --noEmit; fallow audit clean. * feat(studio): assets/blocks panel behaviors + preview helpers What: blocks tab install flow, right-panel and global drag-overlay polish, music beat analysis and clip-content rendering hooks, and the preview-helper utilities backing asset preview. Why: completes the studio NLE stack on top of the visual refresh. How: modified files only (kept as one PR: splitting further would produce sub-150-LOC fragments of interdependent panel glue). Test plan: bunx vitest run studioPreviewHelpers/studioUrlState suites; tsc --noEmit; fallow audit clean. * fix(studio): restore timeline playback loop * fix(studio): restore missing GSAP helpers module * refactor(studio): split timeline GSAP helpers * style(studio): keep timeline helper under size limit * fix(studio): restore timeline overlays module * fix(studio): remove stale GSAP import * fix(studio): restore canonical timeline dependencies * style(studio): format restored timeline helpers * style(studio): satisfy helper line limit * fix(studio): repair rebuilt timeline integration * feat(studio): complete rebuilt NLE cutover * fix(studio): guard project and timeline race boundaries * fix(studio): preserve graded resize and crop geometry * fix(studio): log resize/rotate commit failures, move anchor accumulator to resize-local * fix(studio): treat duration-0 tweens as static holds and settle resize position before persist Instant holds (to()/fromTo() with duration 0) were classified as animated tweens by every commit route, so resizing or rotating them converted the hold into a corrupt duration-0 keyframes tween (new value at 0%, old at 100%) that GSAP drops; panel edits appended a losing set. A shared isInstantHold() now routes them through the static replace-in-place path, and percentage math guards zero-duration windows. Separately, anchored-corner resizes painted 3-5 frames at the new size but old position while the offset persist round-tripped the server. The commit path now applies the corrected GSAP position synchronously before awaiting the offset persist, mirroring the scale route's settle. * feat(studio): gesture-transaction seam with commit observability Introduce runGestureTransaction — one owner for a gesture commit's settle -> persist -> record lifecycle. It settles the live DOM synchronously before any async persist, folds every mutation into one undo entry via a per-transaction coalesceKey, restores pre-gesture state exactly once on failure, and asserts (dev console) + reports (PostHog: commit_transaction / commit_invariant_violation / commit_transaction_failed) that a persist never changes pixels. The box-size resize path is migrated onto it; the ad hoc per-route coalesceKey/reload handling is removed. Extract the resize draft-rect math into resizeDraft.ts to keep the gesture-handler file under the size cap. Also: keep url_hash telemetry to the route slug only (drop the query string, which carried the user's selected element id/selector), and gate the [hf-resize] diagnostics behind localStorage hf-resize-debug so they ship as opt-in tracing rather than console noise. * fix(studio): transaction owns the undo label The coalesced history entry took the last sub-mutation's label, so a resize surfaced as "Move layer" (the offset persist) in undo/redo. The seam now stamps tx.label on every wrapped mutation, so the folded entry reads as the gesture. * fix(studio): atomic static size/position commits (no data loss) Static resize/position holds updated an existing set via delete+add — two undo entries, and a delete that succeeded before a failed add lost the hold on disk. Use one in-place update-properties mutation when a set exists (one undo entry, no partial-failure window). The keyframed-hold heal that can't be expressed as a property update now adds before it deletes, so any single failure leaves a recoverable duplicate, never a lost hold. Transaction-owned commits are tracked via a WeakSet so the heal path never double-wraps an already-wrapped gesture. * fix(core): restore timed-clip visibility after a forced timeline rebind __hfForceTimelineRebind force-rendered the re-registered timeline but never re-ran the per-[data-start] visibility pass, so after undo or soft reload every clip rendered regardless of its time window until a full page reload. Extract the visibility loop into syncTimedElementVisibility and call it from both syncMediaForCurrentState (unchanged) and the rebind. * fix(studio): atomic z-order/keyframe/split commits, one undo entry each Three edit-commit paths hardened onto the one-transaction invariant: - Z-order reorder (useElementLifecycleOps): N per-element writes now fold into one undo entry (coalesceMs Infinity) and, on a failed persist, restore already-written files to disk so no partial reorder survives. - Enable-keyframes (useEnableKeyframes/useGsapKeyframeOps): the intermediate convert phase no longer full-reloads the preview (skipReload), killing the black-flash remount; convert + edit share one coalesce key = one undo entry. - Razor split-all (useRazorSplit): snapshot before the batch and restore on any failure, so a mid-batch error never leaves un-revertable partial splits. Shared file-history helpers (RecordEditInput, DomEditCommitBaseParams, readProjectFileContent, restoreFilesToOriginal) dedupe the rollback/commit logic across these paths. Commit options thread as one partial object rather than field-by-field. Test setup extracted into colocated helpers. * fix(studio): fold multi-step edits into one undo entry; guard text revert - Gesture recording (useGestureCommit): the per-property-group commits now share one coalesce key and only the last reloads, so a recording is one undo entry and one preview reload instead of up to four. - Delete selected keyframes (deleteSelectedKeyframes, split out of timelineEditingHelpers): N removals fold into one coalesced undo entry with a single reload. - Text-field commit (useDomEditTextCommits): commitDomTextFields now uses the same version-guarded revert as handleDomTextCommit, so a stale failed commit can no longer stomp a newer successful one. * feat(studio): batch a gesture's mutations into one atomic server write A transaction that emits N mutations previously did N sequential POSTs, each rewriting the file and soft-reloading — the root of the multi-phase persist window. Add a gsap-mutations-batch endpoint that validates every mutation up front, applies them in one in-memory rewrite chain, and writes the file once (all-or-nothing: an invalid entry rejects the whole batch, no partial write). The seam buffers a transaction's commits and, when more than one targets the same file, dispatches a single batch — one write, one history entry, one reload. The batch capability rides on the existing commit-function reference; no option fields are threaded through callers. * fix(studio): soften off-canvas indicator outline to 30% opacity The dashed off-canvas selection outline at 60% was noisy with many protruding elements on screen; drop the resting opacity to 30% (hover still restores full opacity so it stays discoverable). * fix(studio): drop off-canvas indicator outline to 10% opacity Follow-up to the 30% softening — 10% resting opacity reads much calmer with many protruding elements; hover still restores full opacity. * fix(studio): gate [hf-commit] console traces to dev only The start/settled/persisted/restore lifecycle traces logged on every gesture commit in all environments — console noise for end users. Route them through a dev-only traceCommit helper (matching the pixel-violation error's existing DEV gate). The commit_* PostHog events stay always on; they are the production observability, the console lines are a dev aid. * fix(studio): count actual reloads, not softReload requests, in commit telemetry A resize's size and offset persists both request softReload; the seam counted each request, so a batched gesture reported reload_count 2 even though the batch is one write and one reload. Compute the count from what dispatchBufferedCommits actually did — one for a batch, the request count for the sequential fallback. * fix(studio): rotate hover + off-canvas overlays with the element; flicker-free crop - Hover overlay applied the element's rotation only to the selection chrome, not the hover box; it now rotates about center like the selection, via a shared orientedGroupAwareOverlayRect router (one owner for rotation-aware overlay geometry across hover/selection/off-canvas). - Off-canvas indicator was axis-aligned; it now rotates with the element and inverse-rotates the canvas-exclusion clip into the element's local frame, so the protruding-sliver clip stays correct for rotated elements. - Crop commit re-lifted the element only in the commit's .then(), so one frame painted the cropped state (the flicker). Re-lift synchronously right after onStyleCommit (which applies the clip before its first await), so the cropped state never paints; the persisted file value is unchanged. * fix(studio): address code-review findings across the commit-hardening campaign Correctness (would ship green, bite under latency): - Enable-keyframes phase 2 now carries coalesceMs: Infinity, so the convert folds into one undo entry instead of splitting past the 300ms default. - The SDK keyframe persist path forwards coalesceMs (CutoverOptions gains the field); multi-keyframe delete and convert coalesce correctly when SDK-routed. - Razor split-all's rollback is guarded so a failing restore can't swallow the error toast that tells the user the split failed. Simplification (single source of truth / no dead flexibility): - Decompose resolveResizeDraftRect (drops a fallow-ignore suppression). - Delegate the third readProjectFileContent copy to the shared helper. - Inline setPatchFromUpdateProperties (its only caller passes one mutation). - One toSdkPersistOptions translates gesture overrides to SDK options. - Bundle the reorder-rollback deps into one object (was 7-9 positional args). - Dedupe the 'last group reloads' ternary; type gesture options as CommitMutationOptions; drop a Map+array wrapper around a single write. * feat(studio): atomic z-order reorder via batch patch-element endpoint Z-order reorder issued N per-element inline-style patches (one server write each), so a mid-chain failure could leave a partial reorder on disk. Add a patch-elements-batch endpoint that validates every patch, folds them over the file in one in-memory rewrite, and writes once (all-or-nothing; unsafe input rejects with no write). The reorder now sends one batch per source file and records one undo entry. Because a failed atomic write persists nothing, the interim disk-write-back rollback (restoreReorderedFile / restoreFulfilledReorderFiles / ReorderRollbackDeps) is deleted — failure rolls back only live DOM/store state. Closes the last disk-atomicity gap. * fix(studio): razor-split undo no longer silently no-ops The split clone was written to disk without a data-hf-id, so the split endpoint recorded that unstamped HTML as the undo entry's afterHash. The next reloadPreview() ran the preview route's ensureHfIds write-back, which minted a fresh id and persisted DIFFERENT bytes — so at undo time the disk hash no longer matched afterHash and editHistory's content-mismatch guard silently refused the undo (no write, no network, no error). Stamp the split output via ensureHfIds in splitElementInHtml before it is written/returned, so the preview write-back is a no-op and the recorded afterHash always equals the final on-disk bytes. Fixes at the source rather than relaxing the mismatch guard. Corrects the stale comment that credited forceReloadSdkSession. * feat(studio): closed-hand grab cursor on the rotate handle The rotate handle used the default arrow cursor; show a grabbing (closed-hand) cursor on hover to signal it's grabbed and dragged to rotate. * fix(studio): dropping a dragged element over another no longer selects it A moved drag's release fired the box click, which re-selected whatever now sat under the pointer via the hover cache — so dropping an element over a higher-z one selected the drop target instead of keeping the dragged element selected. The drag-move branch now suppresses the next box click, mirroring the resize branch. * fix(studio): group drag is one undo entry, not one per element Dragging a multi-selected group committed each member's position write as its own undo entry, so reverting took N Cmd+Z presses. Force a shared coalesceKey (infinite window) across every member's commit so they fold into a single undo entry, like the other multi-step commit paths. * fix(studio): undo of a split no longer leaves a ghost clip in the timeline The file and the composition iframe revert correctly on undo, but the timeline panel kept a ghost node for the split clone. The element-merge that repopulates the timeline preserves elements the fresh scan dropped — intended for enriched sub-composition children a bare DOM re-scan misses, but it also preserved a genuinely-removed TOP-LEVEL element (the split clone after undo), leaving a phantom clip. Restrict the preserve to elements with a compositionSrc (the enriched sub-comp children); a top-level element missing from the fresh scan was truly removed. --------- Co-authored-by: ukimsanov <ular.kimsanov@heygen.com>	2026-07-13 02:55:36 -04:00

JamesandClaude Fable 5	267b289bb8	feat(studio): bind selected element properties to variables ... Ninth PR of the template-variables stack: the promote-a-property gesture. Select an element on the canvas/timeline, open the Variables tab, and the panel offers per-property bind actions. - "Bind selected" card in the Variables panel, built from the selection: image/media source (img/video/audio), text, text color, background, and font. Each action declares a variable whose default is the element's CURRENT value (promoting never changes the render — computed rgb colors convert to hex, the first computed font family becomes the font default) and writes the declarative binding the runtime resolves: data-var-src / data-var-text attributes or `<prop>: var(--id)` styles. Declare + bind run as one batched schema edit (one undo step); binding to an already-declared id skips the declare and just binds. - guarded to selections from the composition the session models — a selection in another source file never writes bindings into this one. - core: extract readVariablesForElement into runtime/variableScope.ts, shared by color grading and the declarative bindings (was duplicated). - fix(studio-server): buildSubCompositionHtml's extractElementAttrs rebuilt html/body attributes without HTML-escaping values, shredding quote-bearing attributes — data-composition-variables (a JSON array) came out as mangled bogus attributes, so getVariables() silently returned {} on every /preview/comp/* page (no declared defaults, no runtime bindings). Pre-existing bug surfaced by live-testing this feature; regression test added. Verified end-to-end in a live session: select headline → Bind text color → declaration + var(--headline-color) written to disk → override in the panel → runtime applies the custom prop and the element renders the override.

JamesandClaude Fable 5	2e0b884521	feat(studio-server): preview variable injection + render variables forwarding ... Fourth PR of the template-variables Studio stack — the HTTP plumbing. - preview routes (/preview and /preview/comp/*) accept ?variables=<url-encoded json> and inject `window.__hfVariables = {...}` into <head>, before the runtime and any composition script — the exact global the engine sets via evaluateOnNewDocument at render time, so preview-with-values cannot diverge from render output. Values are escaped against </script> breakout, malformed payloads 400 instead of silently previewing defaults, and the ETag is salted with a hash of the payload so cached previews revalidate when values change. - POST /projects/:id/render accepts variables ({variableId: value}) and forwards them through StudioApiAdapter.startRender into the producer's RenderConfig.variables — the same channel `hyperframes render --variables` uses.

Vance Ingalls	e4c4d2e15d	fix(studio-server): address PR #2097 review feedback on relative-timing resolver ... Documents the shared-pattern context (3rd copy of "resolve relative data-start", after runtime startResolver.ts and the SDK's own getElementTimings) and explains when the raw parseFloat fallback in resolveStart's else branch can actually fire (a malformed grammar string with a leading number). Adds a test pinning the "reference target exists but its own timing is unresolvable" branch, which existing tests didn't cover (only "target doesn't exist" was tested). Cross-checked the negative-offset clamp concern raised in review: the SDK's own resolveReferenceStart (session.ts) also clamps to Math.max(0, ...), so this stays consistent with its sibling — no code change needed there.	2026-07-09 11:27:53 -07:00
Vance Ingalls	fbd21d5709	fix(studio-server): previewAdapter getElementTimings ignores relative data-start refs ... Same bug class as the SDK's getElementTimings fix (#2092): data-start can be a relative-reference expression ("intro", "intro + 2"), not just an absolute number. The old code did a raw parseFloat on it, so any reference silently resolved to undefined instead of an actual time. Also: this function never read data-duration at all (only data-start/data-end literally), so a reference to a duration-authored (not end-authored) clip was unresolvable regardless of the parseFloat bug — resolving a reference needs the target's END, which for a duration-authored clip requires start+duration. Both fixed together via the shared parseStartExpression grammar parser (@hyperframes/core/runtime/start-expression), with the same cycle-guard pattern as the SDK fix. Reference resolution against other elements is scoped to this file's existing findById (bare data-hf-id lookup). 6 new tests: duration-based end resolution, relative reference (with and without offset), missing target, and a mutual-cycle termination check.	2026-07-09 11:27:53 -07:00
Miguel Angel Simon Sierra	9f6c20e482	perf(studio): grow composition duration live on extend, no preview remount ... Extending a clip past the video end used to force the server-fallback path that fully remounts the preview iframe (the SDK fast path can't express the root composition's data-duration, and the runtime bakes+drops data-duration at load so it can't be patched live). On a large comp that remount is a visible hitch. Add a runtime control-bridge action set-root-duration -> clock.setDuration, so the studio can grow the transport length in place. On an extend the studio now posts it (and patches the clip's own timing live) instead of reloading; it only reloads when a GSAP source rewrite actually happened (the gsap-mutation endpoints now report a mutated flag). Non-animated extends — the common case — commit as fast as a normal edit. Verified: bridge dispatch + studio no-reload/post-message paths unit- tested; core/studio/studio-server typecheck + suites green; the built runtime artifact carries the handler; E2E confirms the extend no longer remounts the preview and still persists.	2026-07-08 23:46:28 -04:00

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 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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.

Miguel Ángel	b403c54ae7	feat(studio): restore keyframe retiming — drag-to-retime + Move to Playhead (closes #1782) (#1784) ... * 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.

Miguel Ángel	0a9555a0f7	fix(studio): keyframe/position editing correctness + thumbnail cache busting + local-studio preview discovery (#1781) ... * 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.	2026-06-29 11:23:46 -07:00

Miguel Ángel	7a4853dfe6	refactor: extract @hyperframes/studio-server from core (#1757) ... * refactor: extract @hyperframes/studio-server package from core Moves all studio-api routes, helpers, and Hono server wiring from packages/core/src/studio-api/ into a new standalone packages/studio-server package (@hyperframes/studio-server). Core keeps thin re-export stubs at @hyperframes/core/studio-api and the subpath helpers (screenshot-clip, draft-markers, etc.) for backward compatibility. Consumer imports (cli studioServer, vite adapter/config, producer htmlCompiler, studio manualEditsTypes) are updated to import from @hyperframes/studio-server directly. Also exports rewriteInlineStyleAssetUrls from @hyperframes/core root (was in compiler/rewriteSubCompPaths.ts but not re-exported), required by @hyperframes/studio-server/helpers/subComposition. Removes postcss-selector-parser from @hyperframes/core dependencies (moved to @hyperframes/studio-server which owns the routes that used it). Depends on @hyperframes/parsers (PR #1755). * fix(ci): add parsers+studio-server to Dockerfile and build before preview tests * fix(ci): build @hyperframes/studio-server before Test and studio load smoke Studio's vite.config.ts imports @hyperframes/studio-server, which resolves via its "node" export condition to built dist. The Test and studio-load-smoke jobs only built parsers + core, so esbuild's config load failed to resolve the package entry. Build studio-server too. * fix(studio): repoint sdkCutoverParity test import to studio-server sourceMutation moved from core's studio-api to @hyperframes/studio-server; the test still imported the deleted core path. This was masked while studio's vite.config failed to load (couldn't resolve studio-server); now that the config loads, the test runs and the stale import surfaced.	2026-06-27 01:24:01 -04:00
