Use selectedElementIds as the live selection set with selectedElementId as anchor.
Keep single-click selection as a one-element set and clear both fields together.
handleDomZIndexReorderCommit no longer swallows per-entry save failures: it settles every
patch, and on any rejection rolls back the eager DOM z-index/position and the optimistic
store zIndex before rejecting, so a failed save cannot leave the UI showing a stacking order
that never persisted or let an ordered-after timing write proceed.
Also removes the dead targetTrack parameter threaded through the timeline edit helpers;
vertical placement is owned by the z-index intent.
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.

Sixth PR of the template-variables Studio stack — closing the loop from
preview to render to developer handoff.
- renders started from the Renders tab now carry the active preview
variable overrides (StartRenderOptions.variables → POST /render →
RenderConfig.variables), so "render" produces exactly what the user is
previewing.
- Variables panel "Use this template" footer: copy the effective values
(defaults merged with overrides) as JSON, or as a ready-to-run
`npx hyperframes render <comp> --variables '<json>'` command.
- gitignore: negate the renders/ output rule for the tracked
src/components/renders/ source dir — without it, pre-commit's format
re-stage (`git add {staged_files}`) hard-fails on any change to those
files.
- docs: the Studio panel docs/concepts/variables.mdx described was
aspirational — replace with the real Variables-in-Studio section
(declare/edit, render-truthful preview, render-with-values, handoff,
usage badges); document the new SDK variable APIs in
docs/sdk/reference/composition.mdx (declaration ops, read APIs,
setPreviewVariables).

A drag that both moved a clip in time and restacked it fired two writers on
the same file via separate queues (a targeted z-index patch and a full-file
timing overwrite), so the overwrite could clobber the just-persisted z-index
and the restack silently vanished after reload. The move now awaits the
z-index commit before persisting timing, giving the file one ordered writer
per gesture. Adds a regression test that gates the commit and asserts the
timing write waits.
The ruler now generates ticks across the visible width instead of stopping
at the composition end, so a zoomed-out ruler stays labelled to the right
edge. The tick interval stays pps-driven, so spacing is unchanged. Logic
lives in a new generateVisibleTicks helper to keep Timeline.tsx under the
600-line cap.
When the composition is narrower than the panel (zoomed out) the track
lanes, ruler bar, and context header now fill the whole timeline instead
of stopping at the content width and leaving a flat dark void. Content
stays in composition coordinates, so ticks, clips, and the playhead are
unaffected.
The structural refresh now force-syncs data-active on freshly queried clip
nodes instead of diffing. A clip that changes lanes on a reorder remounts as
a new DOM node; if it stayed under the playhead the diff skipped it and it
rendered as inactive.
Clips share a lane only when they carry the same z-index and don't overlap
in time. Previously a non-overlapping clip packed into the first
time-compatible row regardless of z, so restacking changed the z-index but
the clip's row never followed.
Lane/overlap resolution now uses the clip's authored time span instead
of the live dragged start. A diagonal drag that drifts the clip out of
overlap no longer flips the placement from restack to lane-join, so the
two axes never fight.
CI file-size check and fallow audit caught two issues the --no-verify
commits skipped: Timeline.tsx sat at 602 (max 600) and
postRootDurationToPreview was an unused export (only called in-file).
Trim a comment to hit 600; drop the export.
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.
Dragging a clip past the video end fed back on itself: the growing preview
length shrank the fit-to-width zoom, which remapped the pointer, moved the
clip, and grew the length again (visible jumping). Split the committed
basis duration (drives zoom) from the displayed effective duration (adds
the live preview for ruler + width). Zoom holds fixed through the gesture
and the extra length scrolls; it re-fits once on drop. Duration math
extracted to pure tested helpers in timelineLayout.
Timeline moves and resizes previously snapped only to the beat grid; they
now also snap the dragged edge to other clips' start/end, the playhead,
and the composition bounds, whichever is nearest within the existing
threshold. Beats fold in as one target kind, so beat snapping is
unchanged. Snap logic lives in a new pure timelineSnapTargets module with
unit tests; a snapped edge shows a guide line (beat highlight, else a thin
accent line) for both drag and resize.
A vertical drag onto a lane whose clips overlap the dragged clip in time
used to resolve to the "nearest valid lane", which included the clip's own
lane — so a small drag snapped straight back and felt like the editor
refused the move. Overlapping clips can't share a row (a row is 1-D in
time), but the drag should still restack, never reject.
Now a conflicting onto-drop converts to an edge insertion adjacent to the
target by drag direction (up -> above, down -> below): the clip lands on
its own lane just in front of / behind the target, with its time
unchanged. Non-overlapping drops still join the lane. Deletes the
nearest-valid-placement search (~90 lines) this replaces.
Dragging a timeline clip (or its right resize edge) past the end of the
video now extends the composition duration on drop, instead of clamping
the clip at the current end. Extend-only and undoable.
- Relax the move/resize horizontal clamps that pinned a clip's end at the
current duration; effectiveDuration now folds in the active drag/resize
preview so the ruler and track width grow live as you drag past the end.
- On drop, extend the root composition data-duration (and the store) when
the clip's new end exceeds it, via a shared extendRootDurationInSource
helper extracted from the block installer (now the single owner of that
logic). An extending edit routes through the server persist path since
the SDK setTiming op can't express the root composition's own duration.
Rework the timeline row model from one-row-per-stacking-layer to NLE
"lanes": a row holds a time-sequence of non-overlapping clips, ordered
top = front. Stacking only matters between clips that overlap in time.
- Lane packing: per stacking context, sort clips by effective z-index
desc (DOM order tiebreak) and greedily pack each onto the first lane
whose members don't overlap it in time; else open a new lane. Lane's
representative z is the max member z. Audio stays one clip per lane.
- Lane-aware drag: dropping onto a lane joins it (clip takes the lane's
z) when there's no time-conflict; a conflicting drop is rejected and
the preview snaps to the nearest valid lane or a new-lane insertion.
Between/above/below still create a new lane at that stacking level.
- Overlap checks use the drag-preview start/duration, so conflict is
judged by where the clip lands, not where it started.
Only explicit drags write z-index; authored z is preserved and
data-track-index is never rewritten.
L4 polish for the stacking-layer timeline:
- Sub-composition layers group under a slim "Inside: <comp>" header with a green
accent, so it reads that restacking there is scoped to that context.
- Audio clips render in a distinct bottom lane: separator border, muted row bg,
music glyph in the gutter, beat strip — clearly not part of the z-order stack.
- During a vertical drag, a drop affordance shows join-vs-insert: an "onto"
target highlights the row (join that layer / same z); "between"/"above"/
"below" shows an insertion line (new layer here).
New pure helper timelineDropIndicator.ts (+ test) maps placement -> indicator;
row-group rendering extracted into TimelineLayerGroupHeader / TimelineLayerGutter
/ TimelineDropInsertionLine / TimelineDragGhost to keep files under the 600 cap.
applyTimelineStackingReorder resolved each z-index change by looking the clip up
in the top-level timelineElements list, but sub-composition children live only
in the expanded list, so the lookup missed them and the reorder silently bailed.
Carry the element's locator (domId/selector/sourceFile) on each z-index change
so the commit resolves the live element directly from the preview DOM. Verified
E2E: dragging a clip inside a sub-composition restacks it and patches the
sub-comp source, while the parent composition is untouched.
Adds timelineEditingHelpers.test.ts (locator-based commit + audio no-op).
applyTimelineStackingReorder resolves the live clip from the preview IFRAME,
then gated it with `element instanceof HTMLElement` against the MAIN window's
constructor. Cross-realm instanceof is always false, so every timeline z-index
commit silently bailed ("element not live in iframe") — the drag resolved the
right z but never wrote it. Use the element's own-realm HTMLElement constructor
(matching timelineDOM.ts). Verified end-to-end: dragging a card down now lowers
its z-index and reorders the row, leaving sibling z-indexes untouched.
Unit tests missed this because the happy-dom test iframe shares a realm; caught
via a real-browser Puppeteer E2E drag.
Re-architect the timeline row model from data-track-index rows to stacking
layers. Rows represent stacking layers per context: explicit-z clips merge onto
one track when they share a z and don't overlap in time; auto-z clips stay one
row each (DOM order); audio is pulled into its own bottom lanes. Rows keyed by a
stable layer id, not data-track-index.
Vertical drag always writes z-index, never track: drop onto a layer joins it
(same z), between layers interpolates a new z, past the ends creates a new
front/back layer. data-track-index is never rewritten; #958 holds. Adds
hasExplicitZIndex capture (computed z != auto).
L1: hasExplicitZIndex on the element model
L2: buildStackingTimelineLayers (layer-based rows)
L3: layer-aware vertical drag (join / interpolate / new-extreme)
createTimelineElementFromManifestClip used `clip.zIndex ?? computed`, but the
runtime reports inline-only z-index (0 for CSS-rule authored z-index), and
`0 ?? x` keeps the 0 — so every CSS-styled clip collapsed to a z=0 tie. The
timeline then ordered rows by DOM position instead of true stacking, and the
first vertical drag renumbered the whole tie group, clobbering the author's
z-index. Prefer the effective computed read from the live element (the same
read the reorder commit uses); fall back to the runtime value only when the
element isn't live.
The element stacking key (element.key ?? id) was recomputed in four places
(reorder-intent generation, row ordering, the commit-time sibling lookup via a
threaded keyOf param, and resolveTimelineMove). Any drift would silently break
the sibling lookup and no-op the reorder. Route all of them through the existing
getTimelineElementIdentity owner, share one toStackingOrderItem mapper between
row ordering and reorder intent, and drop the keyOf parameter.
Also enforce the audio side-effect invariant in the single mutation owner
(applyTimelineStackingReorder): dragging an audio clip has no visual layer to
restack, so it never writes z-index. Covered by a new hook test.
Timeline rows now order by scoped stacking (z-index per stacking context)
instead of data-track-index, and dragging a clip up/down commits a targeted
z-index change through the same shared path the layers panel uses. Both panels
stay consistent and moving a clip actually changes front/back. data-track-index
is demoted to time-overlap layout only; no bulk z-index injection (#958 intact).
Also restores beat-snapping on keyframe retiming (re-wires snapKeyframePctToBeat,
orphaned when keyframe dragging was removed) which surfaced while unifying the
model. Extracts pure track-ordering logic to timelineTrackOrder.ts, the stacking
reorder commit + deleteSelectedKeyframes to timelineEditingHelpers.ts, to keep
StudioApp / the timeline hook / Timeline under the studio 600-LOC cap.
U3: scoped stacking row order in the timeline
U4: vertical drag commits z-index via the shared reorder commit
U8: restore keyframe beat-snap on retime
The storyboard view's empty state was a single "no storyboard yet" line. Add a
copy-to-clipboard prompt box (a ready-to-paste handoff prompt carrying the
canonical STORYBOARD.md frontmatter + per-frame format) so users can hand it to
their coding agent, plus a faded skeleton of the contact-sheet grid so landing
on an empty board previews what a filled one looks like instead of a dead end.
Crop is now part of the element selection instead of a separate mode. Selecting
a croppable element shows edge handles just outside each side and, once cropped,
the full content with the cropped-away area dimmed plus a center reposition
handle to pan the crop window. Dragging the body moves the element, edge handles
crop, the center handle pans; corners stay free for the resize handle. Removes
the crop-mode toggle (toolbar + property-panel buttons), the cropMode/
cropAvailable player-store state, and the double-click-to-crop gesture. The
clip-path inset model is unchanged.
The dashed indicators for elements outside the canvas stayed pinned at an element's
old position after a move or a seek: they were recomputed by an effect keyed on
compRect/activeCompositionPath, neither of which changes on an in-place soft-reload
edit or a playhead seek.
They now recompute via a MutationObserver on the preview document (coalesced to one
recompute per frame), so they follow the element live. Crop-hugging is preserved.
Adds a regression test that mutates an element in place and asserts the indicator moves.
Timeline UI
- Highlight clips visible at the playhead in the primary color; others share one neutral color
- Minimalist rounded clips, single-color track rows, no gutter icons or superscript labels
- Per-track eye toggle and a per-element hide button in the design panel
- Ruler zoom fixes: sub-second tick intervals and correct label formatting at high zoom
- Sticky gutter so track controls stay visible while scrolling
WYSIWYG visibility (data-hidden)
- Runtime honors data-hidden (display:none), so hiding affects the render, not just the preview
- HTML stays the source of truth; hide state persists and round-trips on reload
Split several studio files to stay under the 600-line cap; pure relocations, no behavior change.
## What
Brief description of the change.
## Why
Why is this change needed?
## How
How was this implemented? Any notable design decisions?
## Test plan
How was this tested?
- [ ] Unit tests added/updated
- [ ] Manual testing performed
- [ ] Documentation updated (if applicable)
## Summary
Base of the studio UX-review stack (148 findings audited across the studio; 13 critical). This PR hardens the shared `components/ui` primitives that every later PR in the stack builds on.
## Changes
- **Button / IconButton**: visible `focus-visible` outline (studio accent); `disabled:pointer-events-none` removed (replaced with `disabled:cursor-not-allowed`, hover/active gated behind `enabled:`) so disabled buttons can host explain-why tooltips.
- **Tooltip**: keyboard support (`onFocus`/`onBlur` triggers), `role="tooltip"`, Escape-to-hide, viewport flip (top↔bottom) + horizontal clamping. API unchanged — all ~28 call sites unaffected.
- **HyperframesLoader**: `role="status"` on the loader; determinate track is a real `role="progressbar"` with `aria-valuenow/min/max` (was `aria-hidden`).
- **VideoFrameThumbnail**: error event resolves to a static fallback-label tile instead of an infinite shimmer; `motion-reduce` guard.
- **NEW `useDialogBehavior`**: shared modal contract — document-level Escape, Tab focus trap, focus-first-on-open, focus-restore-on-close, `canClose()` veto for dirty-draft guards. Adopted by every modal later in the stack.
- **NEW `SearchInput`**: shared search primitive with required `aria-label`, panel-input token style (kills the two-divergent-search-styles inconsistency in the sidebar).
- **studio.css**: `hf-toast-in/out` + `hf-backdrop-in` keyframes with `prefers-reduced-motion` guards (the previous `animate-in fade-in` classes were dead — no tailwindcss-animate plugin exists).
## Verification
- oxlint 0 errors, oxfmt clean, `tsc --noEmit` clean at stack top
- Full studio suite at stack top: 1189 tests pass
## Stack
PR 1/7 of the studio UX-review fixes. Merges bottom-up; the stack top is fully green (tsc + 1189 tests). Some shared-file edits span PRs, so intermediate branches may not typecheck in isolation.

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

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

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

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

* test(studio): add design-panel QA fixture and triage matrix
Fixture project covering all panel-editable element archetypes,
plus the QA findings matrix from the design-panel bug campaign.
* fix(studio): make canvas selection hit intended elements
- honor author pointer-events:none in hit-testing (was selecting invisible overlays)
- pause playback before mousedown sampling; fall back to hover selection on null resolve
- invalidate committed selection when the active composition changes
- double-click keeps selection and defers to multi-candidate click cycling
* fix(studio): close remaining selection-layer review findings
- hoverSelection fallback now wired at all 3 mousedown call sites (box-click,
blocked-drag, plain overlay click) instead of just the overlay path
- pointer-events override detection reads computed style, not inline style,
so a CSS-class opt-in (not just inline style=) on a descendant is honored
- defensively remove the pointer-events override before the group-fallback
check too, closing a theoretical gap in the no-elementsFromPoint branch
- a click that resolves to nothing (dead-zone / deselect) no longer leaves
playback paused if it was already playing
* fix(studio-server): child-scoped patch operations with batch abort
- PatchOperation gains optional childSelector/childIndex resolved under the matched parent
- pre-pass resolves every op target; any miss aborts the batch with matched:false, no partial write
- style-decl parsing extracted to sourceStyleMutation to stay under the file-size cap
- new ./source-mutation subpath export (mirrors ./finite-mutation)
* fix(studio): per-child patch op builders and persist-seam harness
- buildTextFieldChildLocator indexes over the parent's full same-tag child list
- buildTextFieldChildOperations emits per-field ops for same-shape multi-field edits
- SDK cutover declines child-scoped batches (hfId mapping would hit the parent)
- persist-seam integration harness drives real client ops through patchElementInHtml
* fix(studio): fail closed on unresolved text-field child index
buildTextFieldChildLocator guessed a synthetic field's position by
counting same-tag "child" fields elsewhere in the array whenever
sourceChildIndex was absent. That heuristic is unreachable today (the
count-mismatch guard in buildTextFieldChildOperations already refuses
add/remove edits before it's reached) but would silently locate the
wrong element for a future caller that wires up synthetic-field
support without also computing a real sourceChildIndex. Return null
instead so the caller falls back to the unsupported-structure path.
* fix(studio): surface persist failures with toast and guarded revert
- matched:false and persist errors toast, warn structurally, and revert the optimistic write
- reverts guarded by a per-property version counter so stale failures never stomp newer edits
- structural text-field edits refuse persist instead of writing escaped markup
- multi-field child edits persist via per-child ops; shared commit runner extracted
* fix(studio): revert data-attribute and html-attribute commits on persist failure
commitDataAttribute and handleDomHtmlAttributeCommit toasted on failure but
never reverted the optimistic attribute write, leaving the preview showing an
edit that never reached disk (the exact bug this PR closes for style commits).
Extracted into useDomEditAttributeCommits.ts (useDomEditTextCommits.ts was at
the file-size cap) and routed through runDomEditCommit with a per-target+
attribute version guard, mirroring handleDomStyleCommit.
* fix(studio): close coupled persist-hook review findings
Three findings from R2 review that must land together: a patch-rejection
toast doubled up with the generic persist-failure toast (StudioSaveHttpError
had no alreadyToasted marker), a failed prepareContent write (e.g. font-face
injection) reverted and re-toasted a change the server had already
persisted, and text-commit shouldRevert only rolled back on one narrow
error type instead of any persist failure.
* test(studio): cover persist-failure hook behavior
Regression tests for the persist failure paths: unresolvable targets,
no-op warns, rejected requests, revert races, structural-edit refusal,
and read/write failure toasts.
* test(studio): cover attribute-commit revert on persist failure
Regression tests for the data-attribute and html-attribute revert paths
added in #1910: unresolvable target, rejected request, success (no revert),
and a stale-failure-vs-newer-success race guarded by the per-attribute
version counter.
* test(studio): cover the patch-rejection and text-commit revert fixes
Adds the two persist-hook cases R2 flagged as untested: the
!patchResponse.ok HTTP-error path (previously only exercised via a
network-throw, which bypassed this branch) and handleDomTextCommit's
server-failure path. Also strengthens the prepareContent-write-failure
test to assert the already-persisted base patch is recorded, not
reverted, matching the coupled persist-hook fix.
* test(studio): agent-browser e2e smoke for the design panel
Standalone script driving selection plus one input per panel section
against a running preview, asserting disk persistence and reload survival.
* fix(studio): close smoke-test quality nits, add fault-injection coverage
Closes the R2/R3 findings on the design-panel e2e smoke script:
- Section lookup no longer matches h3 display text plus a manual tree
walk (breaks on wording tweaks). Section now carries a stable
data-panel-section attribute; the script queries by it directly.
- Fields are located by their sibling label (or, where none exists,
by being the section's only input of that type) instead of by
guessing the fixture's current value ahead of time.
- Fixed sleep(1400/2000/6000) waits replaced with polling on the
actual condition (selection registered, section rendered, patch
round-tripped, app booted). This surfaced a real bug while
verifying: computing click coordinates right after a commit reused
a stale preview-frame position from before the property panel's
reflow, silently clicking the wrong spot — now waits for the
frame's rect to stabilize first. Also found and fixed a disk-write
race on the first commit of a run (patch fetch resolves before the
server's file write lands).
- FAIL now dumps window.__patchLog for diagnosability.
- Added a fault-injection cell: the server rejects a patch and the
panel must toast the rejection without persisting it or clobbering
the prior committed value.
Verified by actually running the script with agent-browser against a
live preview (previously never exercised this way) — all 14 checks
pass across repeated clean runs.
* test(studio): add design-panel QA fixture and triage matrix
Fixture project covering all panel-editable element archetypes,
plus the QA findings matrix from the design-panel bug campaign.
* fix(studio): make canvas selection hit intended elements
- honor author pointer-events:none in hit-testing (was selecting invisible overlays)
- pause playback before mousedown sampling; fall back to hover selection on null resolve
- invalidate committed selection when the active composition changes
- double-click keeps selection and defers to multi-candidate click cycling

- hoverSelection fallback now wired at all 3 mousedown call sites (box-click,
blocked-drag, plain overlay click) instead of just the overlay path
- pointer-events override detection reads computed style, not inline style,
so a CSS-class opt-in (not just inline style=) on a descendant is honored
- defensively remove the pointer-events override before the group-fallback
check too, closing a theoretical gap in the no-elementsFromPoint branch
- a click that resolves to nothing (dead-zone / deselect) no longer leaves
playback paused if it was already playing
* fix(studio-server): child-scoped patch operations with batch abort
- PatchOperation gains optional childSelector/childIndex resolved under the matched parent
- pre-pass resolves every op target; any miss aborts the batch with matched:false, no partial write
- style-decl parsing extracted to sourceStyleMutation to stay under the file-size cap
- new ./source-mutation subpath export (mirrors ./finite-mutation)
* fix(studio): per-child patch op builders and persist-seam harness
- buildTextFieldChildLocator indexes over the parent's full same-tag child list
- buildTextFieldChildOperations emits per-field ops for same-shape multi-field edits
- SDK cutover declines child-scoped batches (hfId mapping would hit the parent)
- persist-seam integration harness drives real client ops through patchElementInHtml
* fix(studio): fail closed on unresolved text-field child index
buildTextFieldChildLocator guessed a synthetic field's position by
counting same-tag "child" fields elsewhere in the array whenever
sourceChildIndex was absent. That heuristic is unreachable today (the
count-mismatch guard in buildTextFieldChildOperations already refuses
add/remove edits before it's reached) but would silently locate the
wrong element for a future caller that wires up synthetic-field
support without also computing a real sourceChildIndex. Return null
instead so the caller falls back to the unsupported-structure path.
* fix(studio): surface persist failures with toast and guarded revert
- matched:false and persist errors toast, warn structurally, and revert the optimistic write
- reverts guarded by a per-property version counter so stale failures never stomp newer edits
- structural text-field edits refuse persist instead of writing escaped markup
- multi-field child edits persist via per-child ops; shared commit runner extracted
* fix(studio): revert data-attribute and html-attribute commits on persist failure
commitDataAttribute and handleDomHtmlAttributeCommit toasted on failure but
never reverted the optimistic attribute write, leaving the preview showing an
edit that never reached disk (the exact bug this PR closes for style commits).
Extracted into useDomEditAttributeCommits.ts (useDomEditTextCommits.ts was at
the file-size cap) and routed through runDomEditCommit with a per-target+
attribute version guard, mirroring handleDomStyleCommit.
* fix(studio): close coupled persist-hook review findings
Three findings from R2 review that must land together: a patch-rejection
toast doubled up with the generic persist-failure toast (StudioSaveHttpError
had no alreadyToasted marker), a failed prepareContent write (e.g. font-face
injection) reverted and re-toasted a change the server had already
persisted, and text-commit shouldRevert only rolled back on one narrow
error type instead of any persist failure.
* test(studio): cover persist-failure hook behavior
Regression tests for the persist failure paths: unresolvable targets,
no-op warns, rejected requests, revert races, structural-edit refusal,
and read/write failure toasts.
* test(studio): cover attribute-commit revert on persist failure
Regression tests for the data-attribute and html-attribute revert paths
added in #1910: unresolvable target, rejected request, success (no revert),
and a stale-failure-vs-newer-success race guarded by the per-attribute
version counter.
* test(studio): cover the patch-rejection and text-commit revert fixes
Adds the two persist-hook cases R2 flagged as untested: the
!patchResponse.ok HTTP-error path (previously only exercised via a
network-throw, which bypassed this branch) and handleDomTextCommit's
server-failure path. Also strengthens the prepareContent-write-failure
test to assert the already-persisted base patch is recorded, not
reverted, matching the coupled persist-hook fix.
