Miguel Angel Simon Sierra 1d59e84b23 test(studio): enable thumbnails in the empty-label test (fixes pre-existing failure)
The thumbnails-off-by-default toggle (6b5ea8257) left this test asserting
thumbnail content without enabling thumbnails, so it produced no thumbnail
content and failed. Enable thumbnailsEnabled for the case and reset it in
afterEach; the label ownership assertion is unchanged (TimelineClip owns names).

Miguel Angel Simon Sierra e8a9c7a184 feat(studio): timeline clip thumbnails off by default with a toolbar toggle
Background thumbnail generation (per-clip composition/video frame capture)
lags timeline scrubbing on long videos (#2428). Adds a persisted
thumbnailsEnabled setting, default OFF, so the timeline is snappy out of
the box; a toggle next to Fit in the zoom toolbar turns thumbnails on.
When off, clips render as plain bars (audio still shows its waveform).

Vance Ingalls 8a793ba2b2 fix(studio): gate Layout and Style panel sections on the element having a rendered box
Both panels showed Layout (X/Y/W/H/Rotation/Z-index) unconditionally —
no gate existed for it at all — and Style was gated only on
canEditStyles (a permission check), never on the element's tag. Neither
gate accounted for `<audio>`, which never paints a visual frame, so a
music track's inspector showed a full set of position/size/fill/shadow
controls with zero visual effect.

Add `layout`/`style` applicability to resolveEditingSections (core),
keyed on tag !== "audio", and gate both panels' Layout section and the
existing Style gate on it. Media/Motion/Grade/Text were already
correctly gated (verified via a research pass across both panels) and
are untouched.

Vance Ingalls 14dbfca5a7 fix(studio): give flat Text section rows more vertical breathing room
6px between rows left little clearance above a row's value for the

Vance Ingalls 5f045b6bdf fix(studio): move the promote-to-variable badge above the row instead of a padding gutter
Shrinking the wrapped control's width to make room for the badge (previous
commit) fixed the overlap but pushed the value left unnecessarily. Move the
badge to sit above the row instead, clearing the value without touching its
layout.

Vance Ingalls 9fa1b26570 fix(studio): reserve a gutter for the promote-to-variable badge
PromotableControl absolutely-positions its "◇ var" / "◆ {id}" badge over
the wrapped control without reserving any space, so on rows where the
value renders flush to the right edge (flat Font/Color rows) the badge
sat directly on top of the value text instead of beside it. Add a
right-padding gutter on the wrapper sized to each badge state, and cap
the bound chip to a fixed max-width so it always fits inside its gutter.

Vance Ingalls d5a259a3d2 fix(studio): make flat inspector's Stroke width free of style-name typing
Stroke width committed border-width and border-style together from one
free-text field, so setting a style meant typing an exact CSS keyword
(e.g. "dashed") with no indication of which ones were valid — the row
also duplicated the discoverable Stroke style select directly below it.
Stroke width now only commits border-width; style changes go exclusively
through the existing select.

Vance Ingalls b32f9a3e86 fix(studio): right-align FlatRow's value input in the flat inspector
FlatRow lays out label…gap…value across a `justify-between` row, but the
shared CommitField input it wraps had no text-align, so its text hugged
the LEFT edge of the value's own (often much wider) right-hand box —
looking left-aligned relative to the row, out of step with FlatSelectRow
and FlatSlider, which already right-align.

Added an optional `align` prop to CommitField (default "left", preserving
the legacy panel's MetricField/DetailField layouts where label-then-value
sits inline and left reads naturally) and pass `align="right"` from
FlatRow. Left the Motion Timing row's Start/End/Duration cells alone —
those stack label-above-value in a grid, a different pattern from the
inline label…value row this fix targets.

New tests: FlatRow's input has `text-right` (not `text-left`); the legacy
MetricField's input keeps `text-left` (not `text-right`), pinning
CommitField's default so the shared component doesn't drift for the
panel that didn't ask for this.

Vance Ingalls 578d6202b4 fix(studio): resync the shared SDK session after a Design-panel variable promote
Reported as "template variables are broken": binding an element's field to a
variable via the flat inspector's "◇ var" promote chip (or editing an
already-bound field's value) wrote the correct bytes to disk, but the
Variables tab kept showing the pre-edit value until the whole Studio page
was hard-reloaded.

Root cause: DesignPanelPromoteProvider deliberately opens its OWN SDK
session (`useSdkSession(projectId, selection.sourceFile ?? activeCompPath)`)
so that promoting inside a sub-composition binds the variable in the
sub-comp's own file, not the host's. For the common case — a top-level
element, same file as `activeCompPath` — this session is a SEPARATE
in-memory `Composition` instance from the shared one `VariablesPanel`
(Variables tab, Slideshow, etc.) reads. A persist through the promote
provider's session never fires the shared session's own "change" event.

Worse, the shared session's file-change listener runs
`isSelfWriteEcho(path, content)` to decide whether to reload — but
`sdkSelfWriteRegistry` is keyed by file path only, not by session instance
(its own doc comment assumes "the studio process has a single SDK session
lifecycle at a time"). It sees the promote provider's write registered
under the same path and concludes it's its own echo, permanently
suppressing the reload it actually needs.

Threaded `forceReloadSdkSession` (the same mechanism every other
server-side-write path in Studio already uses for exactly this "resync
after a write I didn't make myself" case) from App.tsx through
StudioRightPanel into DesignPanelPromoteProvider, and call it after every
successful promote/setDefault persist — unconditionally, not gated on the
promote target matching activeCompPath, since re-opening a file that
didn't change is a harmless no-op re-parse and a path-equality guard here
already produced one subtly wrong comparison (activeCompPath can be null
while the shared session still defaults to "index.html") before landing on
this simpler version. Verified live: editing a variable-bound field's
value now updates the Variables tab immediately, no reload required.

App.tsx crossed the 600-line file-size gate after threading the new prop;
extracted the tiny handleAddAssetAtPlayhead wrapper into its own
useAddAssetAtPlayhead hook (with a regression test) to bring it back under.

Vance Ingalls 2b51c52634 fix(studio): give flat-inspector value fields a resting-state input affordance
Every editable value in the flat inspector (FlatRow's CommitField, the
Motion Timing row's Start/End/Duration cells, and every raw <select> —
Style/Text dropdowns, Grade's Custom LUT and Copy-grade-to scope) rendered
its underline/border only on hover (`border-transparent
group-hover:border-...` or no border at all). At rest a value looked like
plain static text, with nothing distinguishing it from a label — testers
reported not being able to tell which fields were editable.

Give each a dim-but-visible resting border (`border-panel-border-input/50`,
or `border-panel-accent/30` for the explicitCustom tier) that brightens on
hover/focus, instead of a fully transparent one. Purely visual — no
behavior change.

Vance Ingalls fb24ecac22 fix(studio): make setRightPanelTab itself flat-aware, not just the direct tab click
Review feedback on #2497 (Rames D Jusso) found a real gap: the exclusivity
this PR introduced only applied to the direct in-panel tab click, which
calls setExclusiveRightInspectorPane. Every OTHER caller that reaches
setRightPanelTab("design"|"layers") — element select (useDomSelection.ts),
closing block-params (App.tsx), the header Inspector button
(StudioHeader.tsx), and even this PR's own "!inspectorTabActive" entry
branch in handleInspectorPaneButtonClick — went through
trackedSetRightPanelTab's old unconditional additive
`{...panes, [tab]: true}`, reproducing the exact "both tabs highlight, only
one renders" bug this PR claims to fix. Confirmed via the reviewer's traced
repro: fresh boot, click Layers tab while no inspector tab is yet active →
rightInspectorPanes ends up {design:true, layers:true}.

Fixed at the reviewer's preferred choke point: trackedSetRightPanelTab
itself is now flat-aware, applying the same exclusive-radio update
setExclusiveRightInspectorPane does whenever STUDIO_FLAT_INSPECTOR_ENABLED
is on, falling back to the legacy additive update otherwise. This closes
the gap for every current and future caller of setRightPanelTab, not just
the one call site this PR touched.

New usePanelLayout.test.ts cases pin both directions: setRightPanelTab
stays additive under flat=off (legacy split-view behavior unchanged), and
enforces exclusivity under flat=on even when called directly (not through
the tab-click handler) — using the vi.doMock(manualEditingAvailability)
pattern already established in PropertyPanel.test.tsx for flag-dependent
module state.

Vance Ingalls 79b688f204 fix(studio): show Layers full-height in the flat inspector, not split with Design
The flat inspector split Layers and Design into a vertically-resizable
stacked pair whenever both panes were toggled on, mirroring the legacy
panel's layout. For the flat redesign this reads as two competing panels
crammed into one column; Layers should always render full-height by
itself there instead.

Gate the split-view branch behind !STUDIO_FLAT_INSPECTOR_ENABLED so it
still applies to the legacy panel, and fall through to Layers rendering
alone (the existing `layersPaneOpen` branch already does this — it just
never got reached previously because the split check ran first).

Also added setExclusiveRightInspectorPane (radio-style: selecting one pane
turns the other off) and use it for the Design/Layers tab clicks under the
flat flag, since leaving both panes independently toggleable would highlight
both tabs as "active" while only one actually renders.

New usePanelLayout.test.ts covers both the existing toggle behavior and the
new exclusive variant. Full studio suite (2634 tests) green; typecheck/
oxlint/oxfmt clean.

WaterrrForever b9be0b2625 feat(skills,studio,media-use): the intent layer, review loop, and user memory — BRIEF.md, companion mode, recipes; /website-to-video folds into /product-launch-video (#2133)
* feat(studio,cli): per-frame board comments, self-refreshing storyboard, status-aware preview landing

Per-frame comment boxes on the storyboard board batch into
.hyperframes/frame-comments.json (a resubmit wins per frame; unconsumed
comments on other frames are kept). Submitted-but-unconsumed comments
stay visible — a toolbar banner plus a per-tile echo — until the agent
consumes the file; the banner also says what to do next (reply anything
in the agent chat).

The board keeps itself current: GET /projects/:id/signature exposes the
watcher-cached project signature, the storyboard payload carries the
signature it was derived from, and the view polls at 2s (hidden tabs
skipped, re-checked on visibility), refetching in place with no loading
flash. Posters bake the signature into their URL so tiles fill in as
sketches land and a poster that failed mid-write retries on the next
version; the empty state upgrades itself when STORYBOARD.md appears,
and its handoff prompt now points the agent at the review loop and uses
the parser's real status vocabulary (outline, not planned).

preview lands the browser on the storyboard view while the board is the
review surface — any frame built, or pure planning (srcs declared, none
on disk yet) — and on the timeline once the video is assembled.

* feat(skills): the review loop — plan, sketch, build as one shared process

hyperframes-core/references/review-loop.md is the single source for the
three-pass collaborative review: the plan proposed on a live board
(§ 1), wireframe sketches marked built with one layout question (§ 2 —
real words on plain blocks, run no CLI; a confirmed board is itself a
valid deliverable when the user asked for a storyboard, not a video),
the build dressing confirmed layouts (§ 3, worker or inline), and the
final look (§ 4). Autonomous runs skip every gate and keep one question
before render.

The three narrative workflows' Steps 3/4/6 collapse to references plus
their sketch stand-ins (captured-asset blocks for product-launch-video,
plain code panels for pr-to-video); the confirmed-sketch handoff stays
in each frame-worker prompt. general-video plans on a board for
multi-scene narrative pieces in collaborative mode — its sketch pass is
layout-before-animation with the user watching. The router treats
"I want a storyboard" as a process request rather than a route, and
closes exploratory intake by recommending a route plus how the run will
review.

The supporting contracts land next door: the comments channel (silent
submit, one reply picks it up, check the file before the words) in
brief-contract § 1; the sidecar schema and the built status rung in
storyboard-format; the mode question asked first and alone in the three
workflows' Step 0.

* feat(media-use): user memory — remembered preferences and frozen recipes

Two tiers of memory on media-use's existing two-tier storage split.

Preferences (lightweight): confirmed brief answers — destination, aspect,
language, mode, voice, style preset — recorded to the project's
.media/preferences.json (committed, the team inherits it) and promoted
to the personal ~/.media/preferences.json once the same value is
confirmed in two different projects (a sightings ledger accumulates the
cross-project evidence user-side, since project files can't see each
other). prefs.mjs get/record; merge reads project-over-user; a changed
value restarts its provenance.

Recipes (heavyweight): one approved run frozen as a named, versioned
bundle — frame.md, the storyboard skeleton (structure kept: durations,
transitions, srcs, Video direction; statuses reset to outline; content
blanked to per-frame fill-ins naming the beat's role), and the confirmed
brief values. Named folders, not content hashes: re-freezing bumps
version and archives <name>@v<N>; a freeze is already confirmed, so it
promotes to the user tier immediately. recipe.mjs freeze/list/use, plus
resolve --type recipe --entity <name> delegating like grade/lut.

16 new node --test cases; the media-use lib suite is 168/168.

* feat(skills): wire user memory into the brief and the review loop

brief-contract § 2 gains Remembered defaults: read the merged
preferences before Round 2 and let a remembered value become the
recommended option with a receipt naming its source project. Memory
changes the default, never the question — every ask-marked field still
gets asked, and what the request says this time beats what was picked
last time. Record only what the user actually confirmed (a defaulted
voice nobody chose is not an answer; a "go" that accepts the
recommended defaults is). The first record announces itself once;
after that the receipts carry the reminder. In autonomous mode a
remembered value becomes the decided value, receipt included.

The three narrative workflows read the remembered defaults before
Round 2, record the confirmed answers at the Step 0 gate, record the
chosen preset at the Step 2 gate (pr-to-video excepted — its preset is
fixed), and fall back to the remembered voice when the request names
none. general-video's discovery reads the same defaults.

Recipes wire in at both ends: Step 0 checks for a matching recipe
before the mode question — one question, plural-aware, and adopting
one fills the brief, skips the design step, and drafts the storyboard
from the frozen skeleton while every review gate still runs. The
review loop's final look (§ 4) offers the freeze once after approval,
and the confirmation teaches the recall phrase — the name is something
the system reminds the user of, never something they must remember.
The router recognizes a named recipe or "like last time" as a route.

Two holes found by a live companion-run freeze: the agent-supplied --workflow
contradicted the run's actual workflow (recipe.json said faceless-explainer,
brief-skeleton said general-video), and the style_preset lookup missed because
the preference had been recorded under the bare key.

- freezeRecipe resolves the workflow from BRIEF.md frontmatter; the flag is a
  fallback for briefless projects and a contradicting flag is ignored (noted).
- recordPreference refuses a bare style_preset — the scoped key is the only
  writable shape; freeze tolerates legacy bare records via read fallback.
- review-loop § 4 / media-use SKILL / brief-format wording follow the machinery.

Vance Ingalls e820e18092 fix(studio): atomic timing pin, expanded-list Hide All, repeated-host matching, pointercancel revert
Fixes real bugs from two independent re-reviews (#2225 @ 65954c3804,
#2416 @ beaf4ffbf6):

- FlatTimingRow's pinRange committed a pinned start+duration range through
  TWO sequential onSetAttribute calls. Each resolves domEditSelection fresh
  from current hook state, so a selection change between the two awaits
  could misdirect the second write at the newly-selected element instead of
  the one being edited, and a failure of just the second call left the pair
  half-applied (inconsistent inferred/explicit state). Added
  commitDataAttributes/handleDomAttributesCommit (mirroring
  onCommitAnimatedProperties's same-shaped fix for GSAP property batches):
  one PatchOperation[] persist call against an explicit, caller-supplied
  selection — not the "current" one — threaded through as the new optional
  onSetAttributes prop. pinRange uses it when provided, falls back to the
  old sequential behavior otherwise.

- Hide All silently dropped nested sub-composition children: a selection
  inside a sub-comp with no timeline-store entry of its own resolves to a
  virtual `sourceFile#domId` key (the fallback branch exists so the
  expansion hook can later resolve it via clipParentMap), but
  toggleTimelineElementHidden only searched the RAW store list, which never
  contains that key. useTimelineElementVisibilityEditing now resolves
  against useExpandedTimelineElements() instead, matching the track-based
  toggle's existing approach — the expanded list synthesizes a real,
  patchable TimelineElement (matching key/domId/sourceFile) for each visible
  child whenever its host is currently expanded.

- Two composition hosts importing the same sub-composition collapsed to
  the first one: findMatchingTimelineElementId ORed domId/selector/
  compositionSrc matches with equal priority in a single per-element scan,
  so `.find()` could stop at an EARLIER, unrelated host that merely shared
  the compositionSrc, before the scan ever reached the correct domId/
  selector match further down the list. Restructured to try domId, then
  selector, across the WHOLE list first; compositionSrc-only matching is
  now a true last resort for when neither identifies a specific element.

- FlatSlider's native pointercancel handler (a platform-level gesture abort
  — scroll/touch takeover, pen leaving range) manually duplicated the
  pointer-capture release logic instead of calling cancelDrag, so it never
  reverted to the pre-drag value — leaving whatever intermediate position
  the pointer last reached committed, unlike the Escape/right-click paths
  added in the previous round. Now calls cancelDrag directly.

- useColorGradingController's flushPendingPersist read identityKeyRef.current
  fresh at flush time rather than a value snapshotted when the edit was
  scheduled. Defensive fix: added pendingPersistIdentityRef, set alongside
  pendingPersistValueRef in commitColorGrading, read by flushPendingPersist
  instead of the live ref — closes the gap regardless of how unlikely the
  actual race is given the identity-cleanup effect's existing eager-flush
  behavior.

Two prior findings re-verified as already fixed further up this same
Graphite stack (not re-fixed here, per established stack-order handling):
metadata-cache negative-caching (267cdfce1) and cross-file
selectionIdentityKey (6f40e03a1), both landing after #2225's reviewed head.

StudioRightPanel.tsx crossed the 600-line file-size gate after wiring the
new onSetAttributes prop through; extracted the inspector split-pane resize
handlers (previously inlined) into their own useInspectorSplitResize hook.

New regression tests: repeated-composition-host resolution, atomic vs.
fallback pinRange commit paths, pointercancel revert. Full studio suite
still at the known pre-existing 55-failure baseline, zero new regressions.
Typecheck/oxlint/oxfmt clean.
