Vance Ingalls 0e9a4f371d feat(audio): open the audio FX, group and mute features to everyone (#3401)
* feat(audio): open the audio FX, group and mute features to everyone

The twelve-PR audio stack landed on main with all three of its canaries still
at 0%, so the FX rack, the group rows, mute and solo are in the build and
reachable by nobody. This removes the gates rather than raising the numbers: a
canary that gates nothing is a branch every future reader has to evaluate.

Gone:
- the `audio-fx-rack`, `audio-track-mute` and `audio-groups` registry entries;
- the five studio gates they fed — the Audio FX section in `PropertyPanelFlat`,
  the mute label, the muted strike-through and the solo button in
  `TimelineTrackPlainHeader`, and the group-row derivation in
  `useTimelineTrackDerivations`. Each feature now renders on its own
  precondition (an audio track, a grouped track) exactly as it did for an
  enrolled user.

The old test pinned `audio-fx-rack` at 0% and asserted it was registered, which
is the opposite of what should hold now. Replaced with a pin that no
`audio-*` canary exists at all: re-registering one silently re-hides a shipped
feature, and nothing else in the tree would say so. Verified it fails when one
is added back.

The equivalent removal on wa-25-review-fixes (#3363) can no longer land — that
branch is 105 commits and 310 files divergent from main now that the stack has
squash-merged past it.

* docs(audio): retire the last references to the audio canaries

Two leftovers the gate removal did not reach.

`TimelineTrackPlainHeader.tsx` still said "Gated: the relabel ships behind the
canary, unlike the preview fix" above the function that picks Mute vs Hide.
Nothing gates it now, so the comment asserted the opposite of the code.

`docs/weekly-updates.mdx` is published, and it told readers the audio work is
"staged behind a canary at zero percent, so none of it is visible by default"
and to "set `HF_CANARY_AUDIO_FX_RACK=on` to use the rack today". That env var
maps to no registry entry any more, so following the instruction does nothing
at all. The week's record stays — it is a dated entry — but it now says the
rollout completed and that the variable is inert.

* fix(studio): name the mute action per track, and pin the newly-live audio rows

Review findings on the canary removal. All three are in code the 0% gate made
unreachable, so this is the first time any of it runs for a user.

*blocker* — `visibilityButtonLabel`'s audio branch returned "Muted" / "Mute":
the current STATE rather than the action, so nothing told a screen-reader user
that activating an already-muted row would unmute it, and it dropped `suffix`,
so every audio row shared one accessible name. Music plus VO is the ordinary
case, which makes that two identical buttons. Now `Unmute track N` /
`Mute track N`, matching the wording `timelineTrackVisibility` already writes
into undo history for the same click. `showAsMute` also picks the icon, so this
is the control's whole identity, not a tooltip.

Tests, for paths that had never executed enabled — a canary at 0% returns
`out_of_cohort` before bucketing, and studio additionally excludes
`navigator.webdriver`, so no suite could reach them:

- `VisibilityButton` — both audio states, two rows staying distinguishable, the
  visual branch unchanged, and the callback still taking the real track key
  rather than the display row. Fails on the old label.
- `useTimelineTrackDerivations` — an ungrouped project stays in raw ascending
  order with no groups, and an interleaved group's members become contiguous
  under an anchor at `memberTracks[0] - 0.5` while the ungrouped track between
  them keeps its place. Plus label/volume/mute mirroring and the id fallback.

Also pins the three retired canary names individually rather than by prefix:
`audio-fx-rack` coming back is caught either way, but `fx-rack` escaped a
`startsWith("audio-")` check. The family guard stays alongside it.

* fix(studio): record the row the mute button announced, not a second derivation

Review finding: the header's track number and the undo-history label's are
computed from two different orderings, and un-gating `audio-groups` is what
makes them diverge.

The header's row comes from the group-aware list — `groupTimelineTracks` emits a
synthetic anchor row per group and pulls members contiguous. The history's comes
from `timelineTrackOrder`, a plain ascending sort of element-bearing keys with no
anchors. On the fixture in this PR's own derivation test, grouped order
`[-0.5, 0, 2, 1]` against ascending `[0, 1, 2]`: clicking mute on the group's
first member said "Mute track 2" and recorded "Mute track 1". Off-cohort this
could not happen — the old branch returned raw tracks, so both sides sorted the
same way.

`onToggleTrackHidden` now carries the display row the clicked control rendered,
and `toggleTimelineTrackHidden` prefers it over deriving its own. One number
instead of two derivations, which is what `timelineTrackDisplay`'s "one owner of
what track number does the user see" already promised. The callback still acts on
the real fractional key, so nothing muted the wrong row before or now — only the
announced and recorded row was wrong.

Also pins the rest of the newly-live surface: the solo button's presence and
pressed state, its absence on a visual track, and the strike-through for both a
row's own mute and a group mute (with the title that says which). Three existing
call-site assertions now check the threaded row too.

Miguel Ángel 5842dd8df4 fix(studio): invalidate the preview signature off the watcher that sees project writes (#3364)
* fix(studio): invalidate the preview signature off the watcher that sees project writes

The preview ETag is a hash of the project's files, memoised per project
directory. That cache was cleared from Vite's own watcher, which
`server.watch.ignored` deliberately excludes `data/projects/**` from, so
nothing ever cleared it: the ETag stayed frozen for the life of the dev
server, the preview answered every revalidation with 304, and the browser
went on serving the composition as it was when it first loaded.

The visible cost is thumbnails. Their disk cache key already content-hashes
the composition, so an edit correctly asks for a fresh capture, but the
capture is taken against the stale page, and a clip's filmstrip keeps
showing frames of a layout that no longer exists until the dev server is
restarted.

Studio already runs its own chokidar watcher over exactly these
directories, because Vite's would answer a composition edit with a full
page reload. That watcher now owns the invalidation, and the cache asks it
to follow any project directory it has not seen. All five event types
count: an added or deleted asset changes the signature as surely as an
edited one.

The cache moves behind `createProjectSignatureCache` so the invalidation
rule is a unit under test rather than a subscription buried in the adapter.

* fix(studio): filter signature invalidation, and stop the CLI server missing motion saves

Review follow-up on the unfiltered invalidation.

The watcher fired on everything under a project dir, but the signature walk
skips 14 directories and `.thumbnails` is one of them. That directory is
where the thumbnail route keeps its disk cache, and every capture also reads
the preview, so populating a timeline row discarded the memo on roughly every
request of the one workload it exists for.

The filter is a single exported predicate beside the exclusion set it reads,
and it is applied inside `invalidate` rather than at the watcher, so no caller
can subscribe and forget it. It is deliberately not `WATCHER_EXCLUDED_DIRS`:
that set is character-identical but drops all of `.hyperframes/`, and the
signature reads two manifest files back out of there.

Which is the same bug, still live, in the CLI server: its watcher filters
through `shouldWatchProjectFile`, so `.hyperframes/studio-motion.json` never
reached the listener that clears the cached signature. Studio writes that file
at runtime, so saving motion state left the preview ETag stale until restart.
The watcher now admits signature-relevant paths and the reload listener
re-applies its own filter, so what triggers a browser reload is unchanged.

Also from review: drop the `createViteAdapter` signature-cache default, which
produced exactly the memo-nothing-clears bug this PR fixes, and correct the
docstring — the content hash is already gated behind a stat fingerprint, so
what the memo saves is the walk.

Vance IngallsandClaude Sonnet 5 6a92d21401 feat(studio,core): reach presets and the rack from the timeline (#3292)
C1: the FX button in the track/group header, and its popover — the
"reach FX from the timeline" entry point, last on purpose because it
targets a group or a single clip, never "a track" (N clips = N chains
is the ill-defined thing the design doc refuses to build).

The button (TimelineFxButton.tsx): renders on group rows and on track
rows holding exactly one audio clip, reading "FX" (or "FX n" once the
target's data-fx-chain has n enabled nodes). A multi-clip ungrouped
audio track gets a pointer instead ("Group these clips to add effects
to all of them" + a Group action) rather than silently hiding the
entry point — reuses B6's exact auto-grouping write
(useAudioGroupCarveAssignment, exposed as onGroupClips) with a minted
group id (mintGroupId, exported from useFxCarveGrouping.ts).

The popover (TimelineFxPopover.tsx, components/editor/): a thin
positioner around FxPresetMenu exactly as the property panel renders
it — same audition contract (useFxAudition), same preset-apply
computation (extracted into useApplyAudioFxPreset.ts's
applyPresetToChain, now shared with propertyPanelFxSection.tsx's own
applyPreset rather than duplicated). Escape closes without
deselecting whatever is behind it; an outside pointerdown dismisses.
Footer's "+ effect"/"Open rack ›" both select the target and hand off
to the property panel (a simplification from the step doc's two
distinct behaviors — remotely toggling the rack's own internal
"adding" state isn't plumbed anywhere, and building that plumbing
would be new UI-state wiring beyond what "reuse existing selection
dispatch" asks for).

Writes, one path per target kind, neither a new persistence mechanism:
- Group: B7/B5's existing onSetAudioGroupAttributeLive/Quiet
  (data-fx-chain, same as data-volume/data-hidden already do).
- Clip: a NEW onSetElementAttributeLive/Quiet pair
  (timelineElementFxAttribute.ts), addressed by the TimelineElement
  itself rather than the current selection. This is the one real
  architectural gap the step doc's assumption didn't survive: the
  property panel's onSetAttributeQuiet closes over domEditSelection,
  so writing a clip that isn't already selected has no synchronous
  path through it. Extracted the shared live-patch-then-persist core
  (persistElementAttribute, timelineEditingHelpers.ts) out of both
  this new path and the existing setAudioGroupAttribute, which the
  fallow duplication gate flagged as a 66-line clone on first pass —
  now a single ~50-line core parameterized by patchLive/readLive, with
  each caller a ~15-line wrapper resolving its own patch target
  (buildPatchTarget({domId}) for a group, buildPatchTarget(element)
  for an arbitrary clip) and live-DOM lookup.

Data plumbing: HfAudioGroup.fxChain (already on the B1 model) mirrored
onto TimelineElement.audioGroupFxChain (timelineDOM.ts's groupInfoFor
cache) and TimelineTrackGroupInfo.fxChain (useTimelineTrackDerivations.ts),
alongside the existing volume/hidden mirrors.

Deferred: the property panel's own rack doesn't (yet) expose a way to
remotely force its add-menu open, so "+ effect" and "Open rack ›"
converge on the same navigation rather than the step doc's two
distinct ones. A grouped multi-clip track (some clips already carry
data-audio-group) gets neither the chain button nor the pointer —
its members' own per-clip FX buttons still work individually, and the
group's own FX button on TimelineGroupHeader covers the group level.

Gates: bun run build clean; packages/studio full suite 4286/4304 (18
pre-existing todo, up from 4276/4294 — 10 new tests, 0 regressions);
new TimelineFxPopover.test.tsx (6) + TimelineFxButton.test.tsx (4)
cover exactly-one-write-per-apply, hover-audition-reverts-on-leave,
Escape-without-deselecting, outside/inside pointerdown dismissal, and
the group-pointer's Group action; oxfmt/oxlint clean on all 22 touched
files; fallow clean (0 new dead-code/unused-export/duplication
findings — the pointer test caught during the first commit attempt).

Vance IngallsandClaude Opus 5 254de3d1c4 fix(studio): captions UX — mode exit, undo, autosave surfacing, honest gating (#1968)
Caption-editing fixes from the studio UX review. This surface held five of
the thirteen criticals; the theme is that the editing UI shipped ahead of
its apply/persist pipeline, so several controls mutated an in-memory model
with no downstream effect, and the mode itself could never be exited.

Mode trap: caption edit mode auto-activated on detection and had no exit —
`setEditMode(false)` and `reset()` had zero call sites, so the caption
overlay replaced normal element editing for the rest of the session, even
after switching compositions. The store now resets on composition change
(flushing the last debounced edit first), an "Editing captions · Exit" pill
sits on the preview, and a re-enter button appears once dismissed.

Honest gating of dead surfaces: the Animation tab (31 presets ×
duration/ease/stagger/intensity) edited state that was never applied to
playback nor serialized — wiring it needs a CaptionOverride schema
extension in packages/core plus a runtime engine, so the tab is now visibly
disabled with an amber "isn't applied to playback or saved yet" notice
instead of silently discarding work. Timing edge-drags moved a block that
never changed playback and never saved; the handles are gone and the blocks
remain as select/seek targets. Double-click split desynced the overlay↔DOM
index mapping, so split is out until regeneration exists.

Undo: store-level undo/redo (cap 50, 800ms coalescing by edit target)
across all ten mutations, with ⌘Z/⇧⌘Z intercepted while caption mode is
active and reapplied to the live iframe. Previously ⌘Z reverted an
unrelated file edit while the bad caption drag persisted.

Autosave: save failures, including non-2xx, raise a persistent "not
saved — Retry" banner; the code's own comment called this a data-loss path
and it was telemetry-only. Debounced saves flush on unmount instead of
being discarded, `beforeunload` flushes and warns while pending, and
corrupt overrides JSON is distinguished from a missing file.

Input safety and a11y: arrow-key nudge no longer hijacks arrows inside
form inputs; numeric fields commit finite values only (typing "-" used to
inject NaN into gsap and persist null); "Mixed" shows on multi-select
divergence; Escape cancels an in-flight drag and restores the pre-drag
transform; ⌘A selects all; caption blocks are keyboard-selectable with a
playhead line and click-to-seek (CaptionTimeline's `onSeek` prop existed
but nothing passed it); 24px hit areas around the 8px handles; a hint when
no boxes are visible; visible input focus styles; tablist semantics.

Perf: the 66ms getBoundingClientRect polling loop is replaced with
event-driven updates (player-store subscription, preview messages,
ResizeObserver, rAF-coalesced); the interval now runs only during playback.

Reconciled against main: StudioPreviewArea.tsx was deleted by the Studio
revamp (#2291), so the mode pill, the sync-error banner and the re-enter
button move to its successor, nle/PreviewOverlays.tsx, and the caption
track's onSeek is wired in EditorShell. The per-keyframe
onChangeKeyframeEase change that also lived in that file is dropped:
main removed the prop, and #1967 now routes the diamond menu's ease action
to the focused-ease-segment editor instead.

Restacked onto main now that PRs 1962-1967 have squash-merged, so this
carries only its own changes.

Vance IngallsandClaude Sonnet 5 0d26072e6c feat(studio,core): mute groups, and hear-only-this that cannot reach the export (#3291)
B5: mute and solo, on groups and tracks (track mute already shipped by A2 —
nothing to build there).

Group mute — persisted as data-hidden on the <hf-audio-group> element itself
(never written onto members, per design doc §2.1's state-restoration
warning). Studio action reuses B7's generic setAudioGroupAttribute
(setQuiet/setLive split) rather than duplicating toggleTimelineTrackHidden's
shape — same one-atomic-patch/one-undo-entry contract, already built for
exactly this purpose. Render: B4 already drops every member of a
data-hidden group (confirmed by a new audioMixer.test.ts case — no
production change needed there). Preview: a dedicated muteGain node
(groupInput -> [fx] -> muteGain -> output -> master) so a mute toggle
never fights scheduleVolumeLane's ramps on the same param — the same
hazard B7's volume fader was split out to avoid. Mid-playback toggles
sync via a new syncAudioGroupMute pass in init.ts (a group carries no
data-start, so it's invisible to the existing visibility-node query).
Members of a muted group render the strikethrough label treatment
(TimelineTrackPlainHeader's isGroupMuted, sourced from
TimelineElement.audioGroupHidden) — display only, no attribute touched.

Solo — "Hear only this": a new session-only store slice (audioSoloSlice,
soloed: ReadonlySet<string> of clip/group ids, never track numbers, never
serialized). Predicate (isAudibleUnderSolo, packages/core/src/audioGroups.ts
so both the store and the preview transport share one definition): an
element is audible while any solo is active only if it or its own group is
soloed. "Siblings, never ancestors" lives in the graph, not the predicate —
solo gain is a per-element stage only; group buses are never attenuated by
solo, so a soloed member's path through its group stays open by
construction. Preview: a dedicated per-element soloGain in
webAudioTransport.ts (parallel to the mute mechanics), pushed via
window.__hf.setAudioSolo — a direct call, not an attribute write, so it
can't ride the visibility-diff path mute uses. media.ts's HTMLMedia
fallback folds the same predicate into its per-tick volume computation
(the same seam A2 used for data-hidden). Half-lit group indicator
(isGroupHalfLitUnderSolo) for "not soloed itself, but a member is".
Exclusive-by-default toggle, ⌘/Ctrl-click to add/remove, TimelineSoloButton
(⌗) beside mute on both track and group headers. Transport-bar banner
("Hearing only <label> — your export is not affected", Clear button) added
in PlayerControls.tsx, reading labels straight off the live preview DOM.

Export-safety, the most important property here: toggling/adding/clearing
solo never calls setAttribute/removeAttribute on any element and never
invokes the project save path (both asserted directly via spies in
audioSoloSlice.test.ts) — solo cannot reach an export by construction, not
by convention.

Also: extracted useHydrateActiveCompPathFromUrl out of App.tsx (a
pre-existing, unrelated effect) to stay under the 600-line filesize cap
after wiring useAudioSoloBridge in; and fixed a circular dependency the
solo-banner wiring introduced (useAudioSoloBridge.ts now imports
usePlayerStore from its concrete module instead of the player/ barrel,
which re-exports PlayerControls.tsx — the barrel path is what closed the
cycle).

Gates: bun run build clean; packages/core full suite 2379/2379; packages/
studio full suite 4276/4294 (18 pre-existing todo); packages/engine
audioMixer.grouping.test.ts 5/5; oxfmt/oxlint clean on all 23 touched
files; fallow clean (0 new circular deps, 0 new filesize/complexity
findings).

Vance IngallsandClaude Opus 5 a01a5d7b3c fix(studio): player UX — honest waveform, keyframe menu actions, beat-delete gesture (#1967)
Player and timeline fixes from the studio UX review, reconciled against six
weeks of main.

Honest media states:
- AudioWaveform no longer falls back to synthesised sine-wave peaks when a
  decode fails. The failure propagates and the clip renders a dashed flat
  line + "waveform unavailable" instead of a plausible waveform an author
  would trim and beat-align against. Main's thumbnail scheduler already
  caches the failure with a TTL, so this neither refetch-loops nor pins the
  degraded state past a transient error.
- VideoThumbnail renders a static "no preview" placeholder on a failed
  decode rather than resolving to an empty box.

Keyframe context menu, restored:
- "Edit Ease…" (showing the current ease) and "Copy Properties" (async,
  "Copied!"/"Copy failed") were plumbed but never rendered. Edit Ease routes
  to the same focused-ease-segment path a segment click takes, so the menu
  advertises the editor that exists instead of growing a second one; it is
  offered only for a keyframe that names a tween to focus. Copy Properties
  matches the keyframe cache on clip-% with the same tolerance main's
  move-to-playhead uses. Every row is a role="menuitem" with arrow-key
  navigation and focus handling via the new useMenuKeyboardNav helper, and a
  separator now isolates "Delete All Keyframes" from the single delete.

Error prevention:
- Beat dots: hit target 12→24px (WCAG 2.5.8), and delete moves off
  double-click to ⌥-click — a stuttered drag reads as a double-click and
  would destroy the beat. ⌥ starts no drag, so a slipped ⌥-drag abandons
  instead of deleting.
- ShortcutsPanel moves focus into the panel on open and returns it to the
  trigger on close; SpeedMenu's trigger is labelled and reports its popup.

Superseded by main, deliberately dropped: the seek-slider keyboard and
aria-valuenow fixes (the transport no longer owns a seek bar), the Player
load-error inline retry (main's reports the actual message and retries with
a cache-busting src), TimelineClip keyboard selection (main renders a native
button, and this PR's onKeyDown would have preventDefault'ed the synthesized
click), the keyframe-diamond keyboard guard and label (both already on main,
with a richer label), and the waveform's own cache/failure maps (main's
scheduler owns that). TimelineOverlays.tsx is a main-side file edited to
thread the two restored menu actions; BeatStrip.test.tsx tracks the new
gesture and hit target.

Restacked onto main now that PRs 1962-1966 have squash-merged, so this
carries only its own changes.

Vance IngallsandClaude Opus 5 44791c3f7d fix(studio): sidebar/panels UX — asset delete confirm, rename, search trap, undo (#1966)
Left-sidebar and slideshow-panel fixes from the studio UX review. Four
criticals: an unconfirmed permanent asset delete, a Rename menu item that
did nothing, a search box that unmounted itself while its filter stayed
applied, and slideshow edits whose persist failures were swallowed.

Asset context menu: Delete shows an inline DeleteConfirm before calling
the API; the dead Rename item is a working inline rename (validates `/`,
`\`, `..`, preserves directory + extension); role="menu"/"menuitem",
Escape, arrow-key nav, focus-into-menu, viewport clamping.

Assets tab: header controls gate on the UNFILTERED asset count, so a
no-match query shows "No assets match" + Clear search instead of
unmounting its own input; cards and font rows are keyboard-operable; a
copy chip surfaces clipboard failure; the import button owns its pending
state; a broken thumbnail names the file type.

Slideshow panel: persist failures raise a "Changes not saved — Retry"
banner (role="alert") with a working retry; in-panel undo stack (50
snapshots, scoped ⌘Z); branch delete confirms inline; reorder buttons
disable at boundaries; HotspotTool explains its prerequisites.

Blocks / compositions tabs: "Added!"/"Copied!" are promise-truthful;
hover-only overlays reveal on focus; PromptPreviewModal gets the dialog
contract + dirty-draft guard; lint dot → labeled count badge; the render
button explains "A render is already in progress"; sidebar tabs are a
real APG tablist; AudioRow coordinates a single preview at a time.

Restacked onto main now that PRs 1962/1963/1964 have squash-merged, so
this carries only its own changes. Reconciled against six weeks of main:
main's newer interaction model wins (rows drag to the timeline, click
reveals the clip or opens the preview, copy is a context-menu action),
and this PR's a11y and error surfacing is ported on top of it. The card
components main extracted to AssetCard.tsx receive the keyboard
activation, focus cues and copy-outcome chip; the "Add at playhead" item
main added joins the rewritten menu's arrow-key order; the Catalog tab is
unconditional since the blocks-panel flag was removed. The row copy chip
is feedback-only — an idle "Copy path" label would describe something the
row no longer does.

Vance IngallsandClaude Sonnet 5 5fd84c395b feat(studio,core): a volume and a living meter on the group row (#3290)
* feat(studio,core): a volume and a living meter on the group row

B7: the group bus strip — droppable, and deliberately minimal per the
casual-user design constraints (groups doc §5): a volume slider, a level
bar that moves with the sound, and the words "Too loud" when it clips. No
dB numbers, no peak-hold readout, no routing row.

Transport (core): groupInput() now routes each group through input -> [FX
chain or dry passthrough] -> output -> master, with one AnalyserNode per
group tapped off `output` (post-FX, so the meter reads what the bus
actually outputs) — fftSize 256, level not spectrum. groupLevel(groupId)
returns RMS-ish level 0..1 + a clipped flag off a reused per-group buffer
(no per-frame allocation), or null when the group is idle/unknown. The
runtime posts group-levels messages only while playing, piggybacking the
existing message channel rather than adding a new poll loop.

Studio: groupLevels.ts is a plain pub-sub store (mirrors liveTime.ts's
shape) fed by useTimelinePlayer's message handler via
parseGroupLevelsMessage; useGroupLevel throttles re-renders to ~33ms.
TimelineGroupBusStrip renders in the group row's own `∿` lane area
(STRIP_H, already sized in B2's row-height pipeline) — drag writes live
via onSetAudioGroupAttributeLive, release commits one undo entry via
onSetAudioGroupAttributeQuiet (packages/studio/src/hooks/
timelineAudioGroupVolume.ts, extracted from timelineTrackVisibility.ts to
stay under the 600-line cap; mirrors FxParamRow's live/commit split).
"Too loud" holds for ~2s after the last clipped block, tracked in the
component, not the transport. volumeByGroup mirrors labelByGroup in
useTimelineTrackDerivations.ts so the strip's slider round-trips the
group's own data-volume.

Fixed two pre-existing group-routing tests in webAudioTransport.test.ts
that hardcoded gain-node creation order/count — B7 inserts an extra
`output` gain node between the group's input and master (for the meter to
tap), which shifted node indices the tests asserted on directly.

* fix(studio,core): keep useTimelinePlayer under the size cap and the level buffer non-shared

Two CI gates, both from this branch's own additions.

`File size check`: `useTimelinePlayer.ts` sat at 599 lines on main and the
group-levels branch pushed it to 605 (cap 600). Extracted the `window.message`
router — which already carried a `fallow-ignore-next-line complexity` admitting
it had outgrown its home — into `previewMessageRouter.ts`, with the fixture
lease, sender check and protocol accept-gate collapsed into one
`acceptedPreviewMessage` so the listener is a flat dispatch and the suppression
is retired rather than moved. Same branches, same refs, no behaviour change;
the file lands at 561.

`Test: runtime contract`: `levelBuf: Float32Array` resolves to
`Float32Array<ArrayBufferLike>` under `tsconfig.runtime.json`, and
`getFloatTimeDomainData` will not take a possibly-shared buffer (TS2345).
Pinned the field to `Float32Array<ArrayBuffer>`, which is what
`new Float32Array(analyser.fftSize)` already produces.

Also drops `EditorShell.selectionSync.test.tsx`'s `vi.mock("./StudioFeedbackBar")`
— main deleted that component in favour of `feedback/StudioFeedbackCard`, and
touching this file for the group prop put the dangling path in fallow's scope.

* feat(core): route grouped audio through a group bus in preview

An audio element carrying `data-audio-group` no longer lands its gain on
the master bus directly — it feeds a per-group `GainNode` (built lazily on
first use, one per group id) which itself feeds master, so members of the
same group sum before the ear, ready for a group-level FX chain and
volume/mute in later steps. An id with no matching `<hf-audio-group>`
element still gets a plain, unprocessed bus rather than losing the track.

The group's own chain and volume lane are wired through the same
`attachElementFxChain`/`scheduleVolumeLane` every element already uses,
against the group's clock — composition time (design doc §1.3), since a
group has no `data-start` and a missing one parses as 0. The bus persists
across `stopAll()` (mirroring `_masterGain`'s own lifecycle) so replaying a
group does not rebuild its chain; only `destroy()` disposes it.

Render is untouched — stays flat until B4; `audio-groups` is still a 0%
canary so nothing ships this to a real composition without hand-authoring
`data-audio-group`.

Also: `audioGroupOf` (B1) crashed on any element lacking a real `tagName`/
`getAttribute` — exactly the shape of most `HTMLMediaElement` test doubles
in this suite, including this file's own `mockEl`. Made it tolerant, same
style as `readChain`'s existing guard in `runtime/audioFx.ts`.

`schedulePlayback` was already 110 lines pre-existing before this diff;
extracted `resolveDestination` and `handleSourceEnded` to shrink it to 92,
then suppressed the remainder (inherently sequential graph wiring, not a
decision tree) per the same precedent B2 used on `TimelineLogicalRow`.

* feat(studio,lint): carve targets voiceover groups — always, when plural

Plural voiceover carve now targets a group instead of naming each clip:
`resolveCarveSourceIds` (core `audioGroups.ts`) expands a group id to its
current members at analysis time, so a clip added to the group later is
covered without touching `sources`. The picker (`useFxCarve.ts`) offers a
grouped voice as one option instead of one row per member, tests overlap
as a union of member spans (a group overlaps the bed if ANY member does),
and prefers a qualifying group over its individual members in
`autoSourceIds`.

Picking two or more ungrouped voice clips in the carve flow now mints a
group behind them (`mintGroupId`, de-duped against every id in the
document) and writes `data-audio-group` on each picked clip atomically,
one undo entry — `createAudioGroupAndAssignMembers` in
`timelineTrackVisibility.ts` copies `setElementsHidden`'s multi-target
write shape. The DSP is untouched: `mixCarveSources` already sums
multiple sources correctly (verified in the design doc's own
investigation) — this only fixes the picker.

New lint rule `audio_carve_ungrouped_sources` (`packages/lint/src/rules/
media.ts`, alongside `audio_volume_double_automation`) warns when a
`data-fx-carve`'s `sources` names two or more plain clip ids instead of a
group — the shape that silently rots when a clip is added. `/hyperframes-
audio` states the same rule as an invariant, not a tip, with the grouped-
narration HTML example from the design doc.

The group-matching and auto-group logic (`withAutoGroupedSources`,
`collectCarveCandidates`) is split into `useFxCarveGrouping.ts` —
`useFxCarve.ts` was pushing past the 600-line cap. `resolveNextCarveSettings`
is deliberately NOT an `async function`: wrapping it in one would force a
microtask on every call, including the synchronous branch — the exact bug
`withAutoGroupedSources`'s own sync-when-possible contract exists to avoid,
and one caught via `propertyPanelAudioFxGroup.test.tsx` (10 failures)
before fixing it back to a plain function the caller conditionally awaits.

Also extracted `useEffectiveTimelineDuration` out of `App.tsx` and
`useRemoveBackground` out of `StudioRightPanel.tsx` (both pushed past 600
lines from an added prop wire), and decomposed `useFxCarve.ts`'s picker
IIFE to clear fallow's complexity gate.

* feat(core): the audio group model — element, membership, helpers

Introduces <hf-audio-group> and data-audio-group as the group model B2–B7
and C1 build on: a non-rendering group element carries a label and (later)
an FX chain, membership lives on the member's own data-audio-group
attribute rather than DOM nesting, so a track removed from the document
simply drops out of the group on the next resolve — nothing dangles.
Groups do not nest: data-audio-group on the group element itself is
ignored. A group with members but no <hf-audio-group> element still
resolves, label falling back to the id, so hand-authored HTML degrades
gracefully. Audio only in v1 — video members are ignored.

Parse-only: nothing routes or sums audio yet (B3/B4). Adds the
audio-groups canary at percentage: 0 gating the future Studio UI; the
element and attribute parse and play regardless of enrollment.

Verified rather than assumed per this plan's standing rule: the timeline's
clip-collection selector ([data-start], [data-track-index],
[data-composition-id], video, audio, img) already excludes the group
element with zero changes, and no lint rule flags unknown elements or
data-* attributes, so neither needed touching — confirmed by grep and by
running `hyperframes lint` against a fixture containing the element (0
findings referencing it). The step doc's suggested display:none injection
point (an existing base stylesheet in the runtime) does not exist in this
codebase; skipped rather than inventing new infrastructure, since an empty,
childless custom element already renders as a zero-size inline box with no
visible output — the same reasoning the lint check above confirms
empirically.

* feat(studio): group rows in the timeline, and a split disclosure

A group renders as its own row with member rows beneath it, and disclosure
splits into two independent controls: caret shows/hides a group's member
rows (structural), `∿` shows/hides any row's automation-lane rows. Plain
tracks lose their caret (nothing to disclose structurally) and keep only
`∿`. `expandedClipIds` keeps its existing keyframe-lane-state job;
`expandedGroupIds`/`expandedLaneOwnerIds` are new, independent sets.

Groups get a real position in the row/geometry pipeline rather than a
visual-only overlay: `useTimelineTrackDerivations` re-emits a group's member
tracks contiguously under a synthetic fractional anchor key
(firstMember - 0.5, the same fractional-key convention sub-composition
expansion already uses), so `rowGeometry`/keyboard-nav/virtualization treat
a group row as a first-class row without widening their key type away from
number. `TimelineLogicalRow.level` widens `1 | 2` to `1 | 2 | 3` (group /
member-under-group / lane), lanes always `owner.level + 1`.

All of it — grouped row emission, the header, the new expansion state — is
gated behind `isCanaryEnabled("audio-groups")`; disabled, `groups` resolves
empty and every new code path no-ops. `TimelineElement.audioGroup` (+
`audioGroupLabel`, resolved once per document via `resolveAudioGroups` from
B1) is parsed unconditionally, mirroring how `hidden`/`fxChain` already
flow DOM → manifest → TimelineElement — inert without the canary.

* fix(core,studio): silence hidden audio in preview, and call it mute

Preview scheduled every audio[data-start] regardless of data-hidden, so a
hidden audio track was silent in the export but audible in preview — render
was already correct, this was a preview-only parity bug. Web Audio scheduling
now skips (and re-syncs on toggle) any audio clip under a data-hidden
ancestor; the HTMLMedia per-tick volume path folds the same check into
effectiveVolume without touching el.muted (transport-owned). Ships unflagged
since it's a bugfix restoring parity.

Also relabels the eye as Mute/Muted on audio-only track rows (icon,
strikethrough label, undo-history copy), gated behind the new
audio-track-mute canary — the relabel is a copy/UX change, kept separate from
the behavior fix above.

* test(core): assert hidden-audio exclusion on the scheduling entry point, not the decode fallback

CI was red on `Test`, `Test: runtime contract` and `Tests on windows-latest` — all three on the
same two tests, both reporting `decodeAudioElement` called 0 times.

Not a bug in this branch. The tests pass on the branch tip and fail on the MERGE with main, which
is what CI actually builds. Main had moved 66 commits ahead, and #3322 ("make creator media edits
render-safe") added `WebAudioTransport.scheduleMediaElementPlayback`: media-element clips now route
straight through the Web Audio graph instead of being decoded into an AudioBuffer.
`decodeAudioElement` survives only as the fallback for the rate-shifted case
(`Math.abs(effectiveRate - 1) > 1e-9`), so on the ordinary path it is correctly never called:

    void webAudio.scheduleMediaElementPlayback(...).then((scheduled) => {
      if (scheduled || !clock.isPlaying()) return;   // <- returns here now
      ...
      void webAudio.decodeAudioElement(rawEl)        // <- fallback only

Both tests used `decodeAudioElement` as a proxy for "this clip reached Web Audio scheduling",
which was accurate before #3322 and is not any more. Retargeted to
`scheduleMediaElementPlayback`, which is that signal now and takes the element as its first
argument, so the assertions keep their exact shape and meaning.

Confirmed by instrumenting the run rather than inferring: on the merged tree the scheduler is
called exactly once, with the audible element — the feature under test works, only the probe was
pointed at the wrong method.

Still non-vacuous: deleting the `rawEl.closest("[data-hidden]")` guard from
`scheduleWebAudioForActiveClips` fails the first test with "expected 1 times, but got 2 times", so
it genuinely catches a hidden clip being scheduled.

`init.test.ts` 77/77, and 1259 passed across packages/core `src/runtime` + `src/audio` on the
merged tree.

Vance IngallsandClaude Fable 5 64b94ebf3a fix(studio): resume drag-paused timelines instead of only re-seeking (#1876)
Drag start pauses every window.__timelines entry and records the list in
data-hf-drag-paused-timelines; resumeGsapTimelines then removed the
attribute and only re-seeked the player, never unpausing anything. The
main timeline survives (seek-driven every frame) but play-state-driven
sub-composition timelines froze permanently after any element drag, and
deselecting could not recover them.

Now unpauses exactly the recorded ids (never touching timelines the drag
did not pause) before the player re-seek. Verified live: after a real
drag on an animated element all scene timelines stay unpaused.

Miguel Ángelandanikam13 f0e637375f fix(studio): capture the storyboard frame hero at full resolution (#3338)
The thumbnail route bounds every preview capture to 240x135. That bound came
from the timeline, where thumbnails are small and numerous and their decoded
bytes are budgeted. The storyboard reuses the same route for its frame detail
hero, which is up to 900px wide, so the poster arrived at 240x135 and upscaled
past 7x on a retina display. Headlines survived it; body copy, table labels and
captions did not.

That is the surface where it costs the most. references/review-loop.md sends the
user here to confirm layout and real copy, and tells them to run no CLI in that
pass: "the poster is the only picture this pass needs".

Give the caller a way to ask for the composition's own dimensions, which the
route already supports as `output=source`, and fold the choice into a single
`surface` prop. Whether a poster is a tile or the hero decides both the crop and
the capture density, so one prop owns both rather than two that can disagree.

The contact sheet keeps the bounded capture: many tiles, and it is a contact
sheet. The timeline is untouched.

Reported with a reproduction and a correct read of the consequences in #3271.

Miguel Ángel 228eabd43f fix(studio): make the volume fader tell the truth about the gain it writes (#3305)
* fix(studio): make the volume fader tell the truth about the gain it writes

The fader travels in dB, so its stops are irrational values; serializing them
through the generic two-decimal numeric formatter collapsed the bottom quarter
of its travel onto "0" — a hard mute — and made the knob jump on release
everywhere below unity. Both panels now use the exact serializer, which
round-trips every integer stop back to itself.

Raise the volume automation lane to the same ceiling the fader reaches.
Clamping the lane at unity meant automating a boosted clip silently discarded
the boost, and the panel disables the fader while a lane owns the level, so
there was no way back. This rescales the lane's vertical axis: unity now sits
a quarter of the way up rather than at the top.

Add audio_volume_tween_overrides_gain. Tween values on `volume` are absolute —
they replace the authored gain rather than scaling it — so a clip carrying both
plays at whatever the tween names, and the fader gives no sign of it. The rule
reuses the tween detector the sibling lane/tween rule already has.

* fix(lint): treat a missing data-volume as unity, not as silence

readAttr returns null when the attribute is absent, and Number(null) is 0 —
finite, and not 1 — so a clip carrying NO data-volume cleared both filters and
was reported as authored at silence. Both halves of that were false: absent
means unity everywhere else in the runtime.

It fired on exactly the case the rule exists to bless. The docs this PR edits
say data-volume is the baseline for elements no tween touches, so a tweened
clip is expected not to carry one — the common audio fade. A warning does not
fail check, but an agent reading the fixHint would have written a gain to
correct a level that was never wrong.

Miguel Ángel 9da422fd7f feat(cli): run a managed background preview in every launch mode (#3310)
`--background` was rejected outside the embedded server. It now re-execs the
CLI in foreground, which makes it mode-agnostic by construction: whichever
server the child resolves to serves the config endpoint the readiness probe
looks for. `--foreground` is its counterpart, for a non-interactive shell that
wants to stay attached, and a bare launch keeps the same promise — attached in
an interactive terminal, managed in an agent session.

That generalization exposed an existing hole. Local-studio mode runs Vite with
the studio package as its cwd and needs that package's own Vite config, which
the published tarball does not carry, but resolving the package was treated as
proof the mode was usable. An npm-installed studio therefore took a path that
can never come up — previously a clear error, now a ten-second silent timeout.
The predicate becomes "can this studio actually be served", so a published
install falls back to embedded mode, which works.

Over the 1k line budget at ~1.3k. The overage is one command file and its
tests carrying one invariant, and the seam that would split it further is
inside a single request-handling function — a split there would produce two
PRs neither of which starts a preview on its own.

Miguel Ángel ec0b23f3ce fix(studio): make Delete remove the whole canvas selection (#3339)
* fix(studio): delete every clip in the selection, not just the first

Select all in the timeline, press Delete, and one clip disappeared while the
rest stayed — still drawn as selected.

The Delete hotkey built the selection set correctly and then called
`elements.find(...)`, which stops at the first match, and handed that single
element to a handler that deletes exactly one. The comment above it claimed the
handler "expands a clip that is part of the multi-selection into an atomic
delete of the whole selection (single undo)" — no such expansion existed
anywhere; `useTimelineEditing` never read `selectedElementIds`.

`handleTimelineElementsDelete` takes the whole selection and removes every
element before saving once, so the delete is a single history entry and a single
undo — what the comment already promised. The hotkey layer now takes only that
plural handler, since it never deletes one element in isolation; the singular
entry point stays for the context menu and clip chrome. The store drops every
deleted key and clears the marquee set, rather than leaving a selection drawn
around clips that no longer exist.

Elements whose `sourceFile` is not the composition being edited are dropped from
the pass rather than written to the wrong file.

Also removes the preview's double-click-to-reset-zoom. It was a document-level
capture listener, so any double-click anywhere over the viewport snapped the
zoom back to fit — including double-clicks meant for the content under it. The
explicit reset control beside the zoom HUD stays.

Reproduced by test: restoring `elements.find` reds the new marquee case.

* fix(studio): delete every canvas element in the selection, not just the primary

Selecting several elements on the canvas and pressing Delete removed one of
them and left the rest — still drawn as selected. The delete path only ever
took the primary selection; the marquee group it belongs to was ignored.

Expand the session-level delete through the group ref, the same way the other
group commits already do, and let the lifecycle op remove every member under a
single save so one Undo restores the whole selection.

* fix(studio): let the canvas selection own Delete instead of its timeline mirror

Marquee-selecting elements on the canvas and pressing Delete removed a
fraction of them. The hotkey routed to the timeline delete whenever the
timeline store held anything, and the timeline's copy of a canvas selection is
derived and lossy by construction — a member with no timeline row of its own is
dropped from it. Selecting 73 elements published 14 ids, so 14 went and 59
stayed, still drawn as selected.

The canvas selection is what the user drew the marquee around, so it owns
Delete whenever it holds something; the timeline path stays as the fallback for
rows with no canvas node to select. Both paths already remove through the same
endpoint, so this is one addressing scheme replacing two.

That makes the canvas delete the path a Delete press normally takes, so it
picks up the same mid-recording refusal the timeline delete has.

* fix(studio): let the marquee see the whole document, not the first 80 elements

Dragging a marquee over the entire canvas selected a fraction of what it
covered, so Delete left most of the page behind. The hit test sourced its
candidates from the layers-panel collector, which stops after 80 items — a
budget for how many rows that panel is willing to render, silently reused as if
it described the document. Everything past the 80th element in document order
was unselectable no matter where the user dragged. The off-canvas indicators
were reading the same truncated list.

The cap now belongs to the panel that wants it; the collector returns
everything. To pay for that, the marquee measures its candidates once when the
drag passes the threshold instead of re-reading layout for every element on
every pointer-move: unbounded plus per-move stalled the tab outright, and the
iframe DOM does not mutate mid-drag, so one pass stays true for the gesture.

On a captured page: one marquee, one Delete, 734 elements down to 81.

* fix(studio): report a no-op delete instead of claiming the elements went

A target the file no longer holds answers `changed: false`, which is normal
for a member nested inside another member already removed. Every target
answering that is not — it means the preview is describing a document the file
does not have, so each removal misses and the file is written back untouched.

The toast still said "Deleted 503 elements. Use Undo to restore them." That is
how a delete that did nothing at all looked from the outside: press Delete, the
page stays, nothing on screen explains it. Say the preview is out of date and
reload it instead.

* fix(studio): keep the canvas hotkeys alive across preview reloads

Pressing Delete with a canvas selection did nothing at all — no removal, no
toast, nothing on screen to explain it. A keypress goes to whichever document
has focus, and clicking the canvas puts focus inside the preview iframe, so the
app's hotkeys have to be forwarded there.

They were, but only from the iframe element's ref callback, which fires when
the element mounts. A preview reload keeps the same element, so the callback
never runs again, and keeps the same WindowProxy, so the forwarder's identity
check saw no change and skipped re-attaching — while the inner window holding
the listeners had been replaced. After the first reload the canvas had no app
hotkeys left. Undo and redo kept working because their forwarder re-attaches on
every load, which is why this read as "only Delete is broken".

Fold the app handler into that per-load forwarder so both attach in the same
place, on every load, and drop the mount-only one. Window only: the history
pair also listens on the document, and capture listeners on both would run the
app handler twice per press.

* perf(studio): stop re-probing every restored selection member on load

The hash carries the whole canvas selection, and restoring it asked the
server whether each member still exists in the source — one request per member,
awaited one after another. A marquee over a captured page puts hundreds of
members in the URL, so every later load of that URL spent hundreds of serial
round trips rebuilding the selection before the canvas answered anything,
keypresses included.

The marquee that produced those members already skips the probe. Restoring them
skips it too; only the primary, whose panel reads the flag, still pays for one.

* fix(studio): delete a canvas selection in one pass and say the key landed

Reproduced with a real, focus-routed keypress instead of a synthetic one: the
press does reach the handler and the delete does run to completion, but at
hundreds of members it takes seconds during which the canvas is unchanged and
nothing acknowledges the key. Silence for that long is indistinguishable from
Delete being broken, and pressing it again or reloading mid-flight lands in a
worse state.

Two things, one per cause. The removal now sends the whole selection in a
single request against a new remove-elements route, which reads the file once,
drops every member and writes once — it was a round trip AND a full rewrite of
the file per element. And a multi-element delete announces itself before the
work starts, so the press is visibly acknowledged instead of leaving the canvas
looking untouched until it finishes.

Measured on a captured page, 84 members: 933ms of serial round trips against
84 rewrites, down to 583ms and one.

* refactor(studio): narrow the SDK delete targets instead of asserting them

The batch SDK path guarded on every member having an hfId and then asserted
it away per member. Narrow once into a string list so the guard and the values
come from the same place, and drop a threaded content variable that never
changed — the SDK owns the document it edits, so every member is removed
against the same starting content.

Also mounts the new forwarding test through the existing harness rather than
repeating its setup.

* fix(studio): stop Delete acting on a canvas selection the user replaced

Two things the reordered Delete arbitration got wrong, both found in review.

A clip with no canvas node left the canvas selection pointing at whatever was
picked before it, and the canvas branch wins whenever that ref is non-null — so
selecting an audio clip and pressing Delete removed the previously selected
canvas element and left the clip, right after the toast said the clip was not
in the preview. The timeline fallback the comment described could not be
reached. Clearing that selection has to stay quiet: the clear is announced to
the timeline, so echoing it would deselect the clip that was just picked.

Expanding the primary to the marquee group also moved out of the delete handler
and up to the Delete key. Cut copies the primary alone, so expanding for every
caller put one element on the clipboard and removed every other member with it
— undo brought them back, paste restored one. The rule is a named function now,
so the two callers can differ without either guessing.

Also throttles the off-canvas indicator rebuild, which the cap had been hiding.
It walks every element in the preview and reads layout for each — measured at
6.5ms on an 825-element captured page against a 16.7ms frame — and what marks
it dirty is a MutationObserver on inline style, which is how animation writes.

* fix(studio): hold the canvas selection inside the timeline selection

The stale-canvas-selection defect survived at the second writer. The
store-driven sync bails when a member has not resolved yet and returned without
touching the canvas, so a pick with no canvas node at all left the previous
selection in place — and Delete acts on the canvas first, so it deleted that.
Reachable from the sidebar audio and asset reveals and from an asset drop, none
of which go through the handler already fixed.

Clearing on every bail would be wrong: the bail exists for a member whose node
is not ready, which a later run resolves, and clearing there would flicker.
Only a canvas anchor that resolves OUTSIDE the current selection goes, which is
the state that is dangerous rather than merely unfinished. Quietly, for the same
reason as the first writer: announcing would deselect the clip just picked.

The invariant is named now, since Delete depends on it: the canvas selection
never points outside the current timeline selection.

Also drops the x-hf-removed header, which nothing read and whose comment
promised a partial-vs-no-op distinction the response cannot make, and pins the
indicator throttle that was measured but uncovered.

Miguel Ángel e282ff15cc fix(audio): raise the authoring gain ceiling and carry it through the probes (#3333)
* fix(audio): raise the authoring gain ceiling and carry it through the probes

Builds on #3328, which made the preview graph apply author gain and user volume
exactly once each. That ownership is now correct but everything is still clamped
to 1.0, so a clip authored above unity cannot be heard or rendered.

`HTMLMediaElement.volume` is spec-clamped to [0,1], so both timeline probes lost
a clip's authored gain the moment it also carried a fade: the probe seeded the
element at the clamped value and every sample read back at or below 0 dB, and
the mixer prefers probed keyframes over the static volume. Both probes now
shadow the accessor for their own duration and forward the clamped value to the
native setter, so the authored gain survives while nothing outside the probe
ever sees an illegal volume.

Measured on one 6 s composition, first 4 s: unity -32.8 LUFS, boosted-with-fade
-32.8 before and -27.0 after — +5.8 dB, exactly the gain the clip was authored
at.

One ceiling, defined once in `audioGain.ts` and reachable from both sides: the
render mixer imports it, and the page-serialized probe takes it as a parameter
rather than re-literalling it. User volume stays spec-clamped — it is a fader,
not a gain.

Also holds the percent volume slider above unity in both property panels. That
control tops out at 100%, so one touch would cap a boosted clip and drop up to
12 dB that now genuinely renders; the dB fader that can represent these levels
replaces it in the next PR.

* fix(audio): carry a static above-unity gain onto the preview gain node

Review follow-up.

`setElementVolume` receives the clip's author gain and clamped it to [0,1],
so a static `data-volume` above unity was capped on the WebAudio preview path
while the render honoured it — the exact preview/render divergence this
ceiling exists to close. Automation lanes hid it: they schedule ramps onto the
param directly and never pass through here. The master volume beside it stays
spec-clamped, because a user fader is not a gain.

Verified by mutation: restoring the [0,1] clamp reds the new case.

Also scope the leveller's rationale to this rung — `VOLUME_RANGE` still stops
at unity until the dB fader lands, so "both now span the same range" was
premature — and say why the GSAP-tracking fallback is unity-capped: it reads
back through `el.volume`, which the spec pins to [0,1], so it cannot observe an
above-unity value however wide the clamp gets.

* fix(audio): restore the live test files this branch overwrote, and uncap preview

Review blocker: three files were wholesale copies from the abandoned #3304
branch laid over a two-day-newer base, so they silently reverted work that had
landed in between. CI could not see it — deleted tests do not fail.

- `audioMixer.test.ts` was byte-identical to #3304's head: 1186 lines against a
  base of 1353. Gone with it were the `data-playback-start` fallthrough cases
  from #3322 — merged 54 minutes before this branch's own merge base — and all
  retiming coverage (`playbackRate` 7 to 0, `atempo` 5 to 0), the strict
  literal-timing table, and the zero-window cases.
- `mediaVolumeEnvelope.test.ts` dropped the trailing-garbage duration case and
  the plateau-retention case.
- `packages/core/package.json` rolled the package version back 0.8.3 to 0.7.109.

All three are restored from `main` with only this PR's additions re-applied on
top, and the subpath export is regenerated by the repo's own script rather than
hand-edited.

Also closes the preview/render split the same review raised. Two clamps had to
go, not one: `setElementVolume` capped the author gain at the transport, and
the first-tick branch in `syncRuntimeMedia` trusted `el.volume` — which is
spec-bound to [0,1] and so cannot represent a boost, opening a boosted clip at
0 dB for one tick before the steady-state branch took over. Both pinned by
tests, both verified by mutation.

Miguel Ángel 5058236eda feat(studio): prompt to install FFmpeg before Export, not after (#3314)
Exporting without FFmpeg installed used to show "Server error (503). Check
the terminal for details." The server already knew the exact cause and sent
a per-platform install command in the response body; Studio discarded that
body and printed the status code. The user found out only after the
composition was finished.

Studio now asks the dev server on load whether this machine can encode, and
the Renders panel shows the cause plus a copyable install command when it
cannot, with a Recheck that avoids restarting Studio.

- New GET /api/environment/ffmpeg calls runEnvironmentChecks() with every
  optional check off, which is exactly the FFmpeg and ffprobe pair `doctor`
  runs, so Studio and the CLI cannot disagree. Only a passing result is
  cached.
- The refusal lives in startRender, not in a button. Studio renders from
  three places (the panel's Export, the header's, and each composition card
  in the sidebar), so a per-button check would leave the others free to
  queue a render that cannot finish. The header and sidebar controls reveal
  the prompt rather than going dead.
- A null probe result means "no answer", not "missing", so an older or
  unreachable dev server cannot lock a working setup.
- Failed render responses now surface the server's { error, hint }.
- getFFmpegInstallCommand() is the single owner of platform-to-command, with
  the prose hint derived from it. Windows gains a winget command and keeps
  the manual download route.

Accessibility: the prompt's explanatory line measured 2.2:1 on the card's
amber background against a 4.5:1 minimum, because the panel's usual grey for
secondary text does not survive the tint. Now 6.6:1. Keyboard focus was
invisible on all three controls and now matches the panel's focus ring.

Also folds in cleanups the repo's gates required: the Renders tab moves out
of StudioRightPanel (it was at the 600-line cap and every field it needed was
already on the shell context), StudioContextInput stops keeping a second copy
of the renderQueue shape, and the server tests share one temp-project helper.

Miguel Ángel 35eb6d2906 refactor(studio): split the two files over the 600-line cap (#3313)
The file size check has been failing on main. It is diff-scoped on a PR but
full-scans packages/studio on push, so two files that crept over the cap were
only ever caught after merge, and every release since has been red:

  TimelineAutomationLane.tsx  674 lines
  StudioRightPanel.tsx        609 lines

Both are pure code moves. No behavior change.

TimelineAutomationLane.tsx keeps the single-lane editor and gives up the
track-level layer: ClipLaneRow, ClipAutomationLanes and
TimelineAutomationLaneSlot move to TimelineAutomationLaneSlot.tsx, which is the
name its test file already used. The dependency runs one way, slot -> lane, so
there is no cycle. 674 -> 499.

StudioRightPanel.tsx gives up its props interface to a sibling .types.ts. That
block is the part that changes least, so moving it keeps the component's own
diffs small; two in-flight branches touch this file and both are based on a
556-line copy of it, so keeping the cut away from the body matters. 609 -> 568.

Verified by running the CI rule's full-scan branch over the 679 tracked
packages/studio source files: no file over 600, exit 0. Studio suite green at
2790 passed across 226 files, and typecheck clean.

Vance IngallsandClaude Sonnet 5 d6c4774ef4 feat(studio): instrument the audio FX rack, including work an agent did (#3229)
* fix(studio): close the typecheck and fallow gaps wa-18b-reschedule opened

useAutomationLanes.ts's write() assumed gesture-scoped coalescing and a
preview-only commit that useDomEditAttributeCommits.ts never grew — backported
that option support from its own later commit so the two sides of the API
agree. The paste path and its tests were missing the box selection's v0/v1
bounds a sibling commit added to AutomationSelection. The FX panel's carve
controls still edited the six mechanism numbers (maxCutDb, bands,
intelligibilityBias) after carveProfile() collapsed authoring to one Strength
knob, so those fields no longer existed on HfCarveSettings; UI now edits
strength, and analyseCarveBands is called with carveProfile(strength).

Also closes fallow's complexity, dead-code and duplication findings on this
PR's diff: extracted automationLaneDragMath.ts (pure group/point-move math)
and useAutomationRangeDrag.ts (the marquee-select gesture) out of
useAutomationLaneGestures.ts, pulled a couple of render-loop ternaries and a
resolver into named functions, dropped an export nothing outside its file
used, and shared a step-simplifier between audioCarve's two envelope
builders.

The edge-stretch vs. box-select priority test in TimelineAutomationLane.test
was still pinning the pre-box-select rule (edge wins over a point sitting on
it) that a sibling commit deliberately reversed — a point inside the box is
now selected content, so grabbing it drags the group instead. Updated the
test to the shipped rule instead of the old one.

* fix(core): cap the via conic's weight so an edge-clamped via point can't NaN

A via point pulled out past the segment (viaX: 5, viaY: -3) clamps to
(0.999, 0.001) — exactly on the steady region's edge, where edge - viaX is 0.
viaConic divided by that zero to get an infinite weight, and shapeVia turned
Infinity into NaN a few steps later (Infinity - Infinity in the quadratic
coefficient). NaN reaching setValueCurveAtTime silences the automated
parameter for the rest of the render.

Capped the weight at 1e6 instead of leaving it unbounded — past that point
the arc already reads as touching the via point, so nothing visible is lost.
Also hardened shapeVia's existing denominator guard (`<= 0`) to `!(> 0)`,
since NaN fails the original comparison and fell through it.

* fix(studio-server): fingerprint the proactive waveform cache key too

The route already keys the waveform cache on the asset's size and mtime as

stale ones. generateWaveformCache — the proactive path that runs on upload —
still called buildWaveformCacheKey with the path alone, so it wrote to a
different key than the route reads from (making the pre-generated cache
never found) and kept the exact collision bug this fingerprint exists to fix
on its own path.

* fix(core): stop \b from missing underscore-separated names, guard clipsOverlap's negative duration

\b treats `_` as a word character, so \bbed\b never matched bed_01,

an underscore-separated bed classified as "unknown" and could end up offered
as its own carve source. Replaced the short hints with a boundary that
actually excludes letters and digits on both sides.

clipsOverlap computed end = start + duration without guarding sign, so a
negative duration put end before start — an interval that does not describe
anything, and one specific case showed it silently dropping a real overlap
(a shorter, earlier broken end rejected a clip that genuinely contained the
point). Duration clamps to zero instead: a clip cannot un-play time, and a
zero-length clip at its start is the sane reading of "duration nobody wrote
down as positive."

Two auto-apply effects both fire when sourceOptions.length === 1: the
multi-candidate effect only guards length === 0, so a single candidate
passes it too, and the single-candidate effect passes its own guard right
after — both compute the same sources list and both call setCarve, so the
common case (one narrator, one bed) triggered two decodes, two FFT runs, and
two concurrent attribute writes for one decision.

The multi-candidate effect now defers to its sibling for exactly one
candidate, which already has its own detailed handling for that case.

* feat(core): carve against every voice over a bed, always (#3212)

* feat(core): carve against every voice over a bed, always dynamically

A bed usually runs under a whole sequence — a narrator, an interview answer, a
second presenter — and carving against one of them left the others fighting it.
`source` becomes `sources`, and `mixCarveSources` sums every voice onto the BED's
clock before anything is measured. That is what keeps one analysis sufficient: the
chain is fixed, so there is no per-voice filter to switch between, and bands drawn
from all the speech there is with envelopes that rise wherever any of it happens
answer the actual question — where and when is speech masking this bed.

Summed rather than averaged: two people talking at once mask more than either
alone. Audio before the bed starts is dropped rather than folded in at zero, since
it plays over nothing and shifting it would put a cut where there is no voice.

`dynamic` is gone. A fixed depth thins the bed through every pause, and once both
have been heard there is no reason to want it, so every carve follows the speech.

Two helpers the panel and the headless script now share instead of each carrying a
copy — two definitions of "what does this name suggest" drift, and then the two
disagree about which track is the voice:

- `classifyAudioName` reads a track's kind from its id and filename together.
  `unknown` is deliberately common: treating an unrecognised name as "not a voice"
  would hide the one track somebody needs to pick.
- `clipsOverlap` keeps out a voice that never plays while the bed does. An unwritten
  duration counts as unbounded, not zero — refusing a clip whose length the
  composition leaves to the media would drop the commonest case there is.

Files written before this still load: a single `source` reads as a one-voice list,
a stored `dynamic` is ignored, and an absent attribute means the defaults whole.

* fix(studio): port the carve UI off the removed source/dynamic fields

#3212 (accidentally squash-merged into this branch instead of main) changed
HfCarveSettings from a single `source` + `dynamic` toggle to a `sources`
list with dynamic mode removed outright — the multi-voice UI consumer that
goes with that shape lands in the very next PR, so this branch was left with
a type that no longer matched its own code.

Minimal port, not the multi-voice redesign that PR does properly: the
"Listen to" picker and analyse() treat sources[0] as the one voice this UI
still understands, and every dynamic-mode branch (the automated envelope
lanes, the toggle, the checkbox) is gone along with the field — a carve is
now always the static value the analysis computes, matching what the type
change made permanent. Test suite trimmed the same way: the automation-lane
and toggle tests covered behavior that no longer exists.

* refactor(studio): break up the FX rack's largest functions and files

Fallow flagged 9 complexity findings and 2 file-size violations after the

FxNodeOpenBody, FxNodeParams, and useFxAudition/useFxCarve/useFxLevelling/
useFxChainObserved out of propertyPanelFxSection.tsx and
propertyPanelAudioFxGroup.tsx, splits propertyPanelFxNodeRow.tsx's open-face
rendering into its own component, and dedupes a clone in studioTelemetry.ts.
Pure structural move — no behavior change; full test suite still green.

* fix(studio): port the carve UI off the removed source/dynamic fields

#3212 (accidentally squash-merged into this branch instead of main) changed
HfCarveSettings from a single `source` + `dynamic` toggle to a `sources`
list with dynamic mode removed outright — the multi-voice UI consumer that
goes with that shape lands in the very next PR, so this branch was left with
a type that no longer matched its own code.

Minimal port, not the multi-voice redesign that PR does properly: the
"Listen to" picker and analyse() treat sources[0] as the one voice this UI
still understands, and every dynamic-mode branch (the automated envelope
lanes, the toggle, the checkbox) is gone along with the field — a carve is
now always the static value the analysis computes, matching what the type
change made permanent. Test suite trimmed the same way: the automation-lane
and toggle tests covered behavior that no longer exists.

Vance IngallsandClaude Opus 5 6bcf739390 fix(studio): audition from the playhead while paused, and let an author out of a menu (#3190)
* fix(studio): close the typecheck and fallow gaps wa-18b-reschedule opened

useAutomationLanes.ts's write() assumed gesture-scoped coalescing and a
preview-only commit that useDomEditAttributeCommits.ts never grew — backported
that option support from its own later commit so the two sides of the API
agree. The paste path and its tests were missing the box selection's v0/v1
bounds a sibling commit added to AutomationSelection. The FX panel's carve
controls still edited the six mechanism numbers (maxCutDb, bands,
intelligibilityBias) after carveProfile() collapsed authoring to one Strength
knob, so those fields no longer existed on HfCarveSettings; UI now edits
strength, and analyseCarveBands is called with carveProfile(strength).

Also closes fallow's complexity, dead-code and duplication findings on this
PR's diff: extracted automationLaneDragMath.ts (pure group/point-move math)
and useAutomationRangeDrag.ts (the marquee-select gesture) out of
useAutomationLaneGestures.ts, pulled a couple of render-loop ternaries and a
resolver into named functions, dropped an export nothing outside its file
used, and shared a step-simplifier between audioCarve's two envelope
builders.

The edge-stretch vs. box-select priority test in TimelineAutomationLane.test
was still pinning the pre-box-select rule (edge wins over a point sitting on
it) that a sibling commit deliberately reversed — a point inside the box is
now selected content, so grabbing it drags the group instead. Updated the
test to the shipped rule instead of the old one.

* fix(core): cap the via conic's weight so an edge-clamped via point can't NaN

A via point pulled out past the segment (viaX: 5, viaY: -3) clamps to
(0.999, 0.001) — exactly on the steady region's edge, where edge - viaX is 0.
viaConic divided by that zero to get an infinite weight, and shapeVia turned
Infinity into NaN a few steps later (Infinity - Infinity in the quadratic
coefficient). NaN reaching setValueCurveAtTime silences the automated
parameter for the rest of the render.

Capped the weight at 1e6 instead of leaving it unbounded — past that point
the arc already reads as touching the via point, so nothing visible is lost.
Also hardened shapeVia's existing denominator guard (`<= 0`) to `!(> 0)`,
since NaN fails the original comparison and fell through it.

still called buildWaveformCacheKey with the path alone, so it wrote to a

never found) and kept the exact collision bug this fingerprint exists to fix

The 20s margin (already once widened for the same reason) is timing out in

Two auto-apply effects both fire when sourceOptions.length === 1: the
multi-candidate effect only guards length === 0, so a single candidate
passes it too, and the single-candidate effect passes its own guard right
after — both compute the same sources list and both call setCarve, so the
common case (one narrator, one bed) triggered two decodes, two FFT runs, and
two concurrent attribute writes for one decision.

The multi-candidate effect now defers to its sibling for exactly one
candidate, which already has its own detailed handling for that case.

* feat(core): carve against every voice over a bed, always (#3212)

* feat(core): carve against every voice over a bed, always dynamically

A bed usually runs under a whole sequence — a narrator, an interview answer, a
second presenter — and carving against one of them left the others fighting it.
`source` becomes `sources`, and `mixCarveSources` sums every voice onto the BED's
clock before anything is measured. That is what keeps one analysis sufficient: the
chain is fixed, so there is no per-voice filter to switch between, and bands drawn
from all the speech there is with envelopes that rise wherever any of it happens
answer the actual question — where and when is speech masking this bed.

Summed rather than averaged: two people talking at once mask more than either
alone. Audio before the bed starts is dropped rather than folded in at zero, since
it plays over nothing and shifting it would put a cut where there is no voice.

`dynamic` is gone. A fixed depth thins the bed through every pause, and once both
have been heard there is no reason to want it, so every carve follows the speech.

Two helpers the panel and the headless script now share instead of each carrying a
copy — two definitions of "what does this name suggest" drift, and then the two
disagree about which track is the voice:

- `classifyAudioName` reads a track's kind from its id and filename together.
  `unknown` is deliberately common: treating an unrecognised name as "not a voice"
  would hide the one track somebody needs to pick.
- `clipsOverlap` keeps out a voice that never plays while the bed does. An unwritten
  duration counts as unbounded, not zero — refusing a clip whose length the
  composition leaves to the media would drop the commonest case there is.

Files written before this still load: a single `source` reads as a one-voice list,
a stored `dynamic` is ignored, and an absent attribute means the defaults whole.

Vance IngallsandClaude Opus 5 2020b82c9b feat(studio): family lettering, tints, and the rack as a signal path (#3187)
* fix(studio): close the typecheck and fallow gaps wa-18b-reschedule opened

useAutomationLanes.ts's write() assumed gesture-scoped coalescing and a
preview-only commit that useDomEditAttributeCommits.ts never grew — backported
that option support from its own later commit so the two sides of the API
agree. The paste path and its tests were missing the box selection's v0/v1
bounds a sibling commit added to AutomationSelection. The FX panel's carve
controls still edited the six mechanism numbers (maxCutDb, bands,
intelligibilityBias) after carveProfile() collapsed authoring to one Strength
knob, so those fields no longer existed on HfCarveSettings; UI now edits
strength, and analyseCarveBands is called with carveProfile(strength).

Also closes fallow's complexity, dead-code and duplication findings on this
PR's diff: extracted automationLaneDragMath.ts (pure group/point-move math)
and useAutomationRangeDrag.ts (the marquee-select gesture) out of
useAutomationLaneGestures.ts, pulled a couple of render-loop ternaries and a
resolver into named functions, dropped an export nothing outside its file
used, and shared a step-simplifier between audioCarve's two envelope
builders.

The edge-stretch vs. box-select priority test in TimelineAutomationLane.test
was still pinning the pre-box-select rule (edge wins over a point sitting on
it) that a sibling commit deliberately reversed — a point inside the box is
now selected content, so grabbing it drags the group instead. Updated the
test to the shipped rule instead of the old one.

* fix(core): cap the via conic's weight so an edge-clamped via point can't NaN

A via point pulled out past the segment (viaX: 5, viaY: -3) clamps to
(0.999, 0.001) — exactly on the steady region's edge, where edge - viaX is 0.
viaConic divided by that zero to get an infinite weight, and shapeVia turned
Infinity into NaN a few steps later (Infinity - Infinity in the quadratic
coefficient). NaN reaching setValueCurveAtTime silences the automated
parameter for the rest of the render.

Capped the weight at 1e6 instead of leaving it unbounded — past that point
the arc already reads as touching the via point, so nothing visible is lost.
Also hardened shapeVia's existing denominator guard (`<= 0`) to `!(> 0)`,
since NaN fails the original comparison and fell through it.

* fix(studio-server): fingerprint the proactive waveform cache key too

The route already keys the waveform cache on the asset's size and mtime as
well as its path, so a rebuilt-in-place file gets fresh peaks instead of
stale ones. generateWaveformCache — the proactive path that runs on upload —
still called buildWaveformCacheKey with the path alone, so it wrote to a
different key than the route reads from (making the pre-generated cache
never found) and kept the exact collision bug this fingerprint exists to fix
on its own path.

* style(docs): run oxfmt on the /hyperframes-audio skill docs

Table column widths had drifted out of alignment with oxfmt's own rules,
failing format:check and blocking the Preflight gate every downstream
branch inherits. Whitespace only, no content change.

* fix(core): stop \b from missing underscore-separated names, guard clipsOverlap's negative duration

\b treats `_` as a word character, so \bbed\b never matched bed_01,
music_bed_loop, or theme_song, and \bvo\b/\bvox\b/\btts\b had the same gap —
an underscore-separated bed classified as "unknown" and could end up offered
as its own carve source. Replaced the short hints with a boundary that
actually excludes letters and digits on both sides.

clipsOverlap computed end = start + duration without guarding sign, so a
negative duration put end before start — an interval that does not describe
anything, and one specific case showed it silently dropping a real overlap
(a shorter, earlier broken end rejected a clip that genuinely contained the
point). Duration clamps to zero instead: a clip cannot un-play time, and a
zero-length clip at its start is the sane reading of "duration nobody wrote
down as positive."

Review by Miga (PR #3212).

* fix(studio): widen PropertyPanel's resetModules render timeout again

The 20s margin (already once widened for the same reason) is timing out in
CI's full-monorepo Test run — the resetModules()+fresh-import render this
test needs is uncached and competes with every other package's test suite
for the same worker pool, and the same test passes in well under 2s
standalone. Went to 45s rather than re-tuning to whatever number happens to
clear the current CI load, since that number moves every time CI gains a
package.

* fix(studio): stop the single-candidate auto-apply carve firing twice

Two auto-apply effects both fire when sourceOptions.length === 1: the
multi-candidate effect only guards length === 0, so a single candidate
passes it too, and the single-candidate effect passes its own guard right
after — both compute the same sources list and both call setCarve, so the
common case (one narrator, one bed) triggered two decodes, two FFT runs, and
two concurrent attribute writes for one decision.

The multi-candidate effect now defers to its sibling for exactly one
candidate, which already has its own detailed handling for that case.

Review by Miga (PR #3213).

* feat(core): carve against every voice over a bed, always (#3212)

* feat(core): carve against every voice over a bed, always dynamically

A bed usually runs under a whole sequence — a narrator, an interview answer, a
second presenter — and carving against one of them left the others fighting it.
`source` becomes `sources`, and `mixCarveSources` sums every voice onto the BED's
clock before anything is measured. That is what keeps one analysis sufficient: the
chain is fixed, so there is no per-voice filter to switch between, and bands drawn
from all the speech there is with envelopes that rise wherever any of it happens
answer the actual question — where and when is speech masking this bed.

Summed rather than averaged: two people talking at once mask more than either
alone. Audio before the bed starts is dropped rather than folded in at zero, since
it plays over nothing and shifting it would put a cut where there is no voice.

`dynamic` is gone. A fixed depth thins the bed through every pause, and once both
have been heard there is no reason to want it, so every carve follows the speech.

Two helpers the panel and the headless script now share instead of each carrying a
copy — two definitions of "what does this name suggest" drift, and then the two
disagree about which track is the voice:

- `classifyAudioName` reads a track's kind from its id and filename together.
  `unknown` is deliberately common: treating an unrecognised name as "not a voice"
  would hide the one track somebody needs to pick.
- `clipsOverlap` keeps out a voice that never plays while the bed does. An unwritten
  duration counts as unbounded, not zero — refusing a clip whose length the
  composition leaves to the media would drop the commonest case there is.

Files written before this still load: a single `source` reads as a one-voice list,
a stored `dynamic` is ignored, and an absent attribute means the defaults whole.

* fix(studio): port the carve UI off the removed source/dynamic fields

#3212 (accidentally squash-merged into this branch instead of main) changed
HfCarveSettings from a single `source` + `dynamic` toggle to a `sources`
list with dynamic mode removed outright — the multi-voice UI consumer that
goes with that shape lands in the very next PR, so this branch was left with
a type that no longer matched its own code.

Minimal port, not the multi-voice redesign that PR does properly: the
"Listen to" picker and analyse() treat sources[0] as the one voice this UI
still understands, and every dynamic-mode branch (the automated envelope
lanes, the toggle, the checkbox) is gone along with the field — a carve is
now always the static value the analysis computes, matching what the type
change made permanent. Test suite trimmed the same way: the automation-lane
and toggle tests covered behavior that no longer exists.

Infinity into NaN a few steps later (Infinity - Infinity in the quadratic
coefficient). NaN reaching setValueCurveAtTime silences the automated
parameter for the rest of the render.

Capped the weight at 1e6 instead of leaving it unbounded — past that point
the arc already reads as touching the via point, so nothing visible is lost.
Also hardened shapeVia's existing denominator guard (`<= 0`) to `!(> 0)`,
since NaN fails the original comparison and fell through it.

* fix(studio-server): fingerprint the proactive waveform cache key too

The route already keys the waveform cache on the asset's size and mtime as
well as its path, so a rebuilt-in-place file gets fresh peaks instead of
stale ones. generateWaveformCache — the proactive path that runs on upload —
still called buildWaveformCacheKey with the path alone, so it wrote to a
different key than the route reads from (making the pre-generated cache
never found) and kept the exact collision bug this fingerprint exists to fix
on its own path.

* style(docs): run oxfmt on the /hyperframes-audio skill docs

Table column widths had drifted out of alignment with oxfmt's own rules,
failing format:check and blocking the Preflight gate every downstream
branch inherits. Whitespace only, no content change.

* fix(core): stop \b from missing underscore-separated names, guard clipsOverlap's negative duration

\b treats `_` as a word character, so \bbed\b never matched bed_01,
music_bed_loop, or theme_song, and \bvo\b/\bvox\b/\btts\b had the same gap —
an underscore-separated bed classified as "unknown" and could end up offered
as its own carve source. Replaced the short hints with a boundary that
actually excludes letters and digits on both sides.

clipsOverlap computed end = start + duration without guarding sign, so a
negative duration put end before start — an interval that does not describe
anything, and one specific case showed it silently dropping a real overlap
(a shorter, earlier broken end rejected a clip that genuinely contained the
point). Duration clamps to zero instead: a clip cannot un-play time, and a
zero-length clip at its start is the sane reading of "duration nobody wrote
down as positive."

* fix(studio): widen PropertyPanel's resetModules render timeout again

The 20s margin (already once widened for the same reason) is timing out in
CI's full-monorepo Test run — the resetModules()+fresh-import render this
test needs is uncached and competes with every other package's test suite
for the same worker pool, and the same test passes in well under 2s
standalone. Went to 45s rather than re-tuning to whatever number happens to
clear the current CI load, since that number moves every time CI gains a
package.

* fix(studio): stop the single-candidate auto-apply carve firing twice

Two auto-apply effects both fire when sourceOptions.length === 1: the
multi-candidate effect only guards length === 0, so a single candidate
passes it too, and the single-candidate effect passes its own guard right
after — both compute the same sources list and both call setCarve, so the
common case (one narrator, one bed) triggered two decodes, two FFT runs, and
two concurrent attribute writes for one decision.

The multi-candidate effect now defers to its sibling for exactly one
candidate, which already has its own detailed handling for that case.

* feat(core): carve against every voice over a bed, always (#3212)

* feat(core): carve against every voice over a bed, always dynamically

A bed usually runs under a whole sequence — a narrator, an interview answer, a
second presenter — and carving against one of them left the others fighting it.
`source` becomes `sources`, and `mixCarveSources` sums every voice onto the BED's
clock before anything is measured. That is what keeps one analysis sufficient: the
chain is fixed, so there is no per-voice filter to switch between, and bands drawn
from all the speech there is with envelopes that rise wherever any of it happens
answer the actual question — where and when is speech masking this bed.

Summed rather than averaged: two people talking at once mask more than either
alone. Audio before the bed starts is dropped rather than folded in at zero, since
it plays over nothing and shifting it would put a cut where there is no voice.

`dynamic` is gone. A fixed depth thins the bed through every pause, and once both
have been heard there is no reason to want it, so every carve follows the speech.

Two helpers the panel and the headless script now share instead of each carrying a
copy — two definitions of "what does this name suggest" drift, and then the two
disagree about which track is the voice:

- `classifyAudioName` reads a track's kind from its id and filename together.
  `unknown` is deliberately common: treating an unrecognised name as "not a voice"
  would hide the one track somebody needs to pick.
- `clipsOverlap` keeps out a voice that never plays while the bed does. An unwritten
  duration counts as unbounded, not zero — refusing a clip whose length the
  composition leaves to the media would drop the commonest case there is.

Files written before this still load: a single `source` reads as a one-voice list,
a stored `dynamic` is ignored, and an absent attribute means the defaults whole.

* fix(studio): port the carve UI off the removed source/dynamic fields

#3212 (accidentally squash-merged into this branch instead of main) changed
HfCarveSettings from a single `source` + `dynamic` toggle to a `sources`
list with dynamic mode removed outright — the multi-voice UI consumer that
goes with that shape lands in the very next PR, so this branch was left with
a type that no longer matched its own code.

Minimal port, not the multi-voice redesign that PR does properly: the
"Listen to" picker and analyse() treat sources[0] as the one voice this UI
still understands, and every dynamic-mode branch (the automated envelope
lanes, the toggle, the checkbox) is gone along with the field — a carve is
now always the static value the analysis computes, matching what the type
change made permanent. Test suite trimmed the same way: the automation-lane
and toggle tests covered behavior that no longer exists.

Vance IngallsandClaude Opus 5 2f97fc2b89 refactor(studio): lift the effect row out of the FX section file (#3182)
* fix(studio): drop the unused DomEditSelection import in PropertyPanelFlat

CI caught it on PR #3026 (wa-12-panel-params); a later refactor in the
stack removed the last use of the type here without removing the import.

* fix(studio): close the typecheck and fallow gaps wa-18b-reschedule opened

useAutomationLanes.ts's write() assumed gesture-scoped coalescing and a
preview-only commit that useDomEditAttributeCommits.ts never grew — backported
that option support from its own later commit so the two sides of the API
agree. The paste path and its tests were missing the box selection's v0/v1
bounds a sibling commit added to AutomationSelection. The FX panel's carve
controls still edited the six mechanism numbers (maxCutDb, bands,
intelligibilityBias) after carveProfile() collapsed authoring to one Strength
knob, so those fields no longer existed on HfCarveSettings; UI now edits
strength, and analyseCarveBands is called with carveProfile(strength).

Also closes fallow's complexity, dead-code and duplication findings on this
PR's diff: extracted automationLaneDragMath.ts (pure group/point-move math)
and useAutomationRangeDrag.ts (the marquee-select gesture) out of
useAutomationLaneGestures.ts, pulled a couple of render-loop ternaries and a
resolver into named functions, dropped an export nothing outside its file
used, and shared a step-simplifier between audioCarve's two envelope
builders.

The edge-stretch vs. box-select priority test in TimelineAutomationLane.test
was still pinning the pre-box-select rule (edge wins over a point sitting on
it) that a sibling commit deliberately reversed — a point inside the box is
now selected content, so grabbing it drags the group instead. Updated the
test to the shipped rule instead of the old one.

* fix(core): cap the via conic's weight so an edge-clamped via point can't NaN

A via point pulled out past the segment (viaX: 5, viaY: -3) clamps to

viaConic divided by that zero to get an infinite weight, and shapeVia turned
Infinity into NaN a few steps later (Infinity - Infinity in the quadratic
