* fix(core): bundled local scripts keep their own place, defer and async
The bundler joined every local <script src> into one inline script at the first one's position. That dropped defer and async (a deferred main.js ran before a deferred CDN gsap), moved later files ahead of CDN scripts between them, and let one file's error stop the rest. Each local script is now inlined where it stands with its attributes; a deferred or async one keeps its tag with its file as a data: URL. Inline-script merging also no longer folds in nomodule scripts, which dropped the attribute.
* fix: preview scripts run after the runtime when the bundler fails, and inlined files are escaped
- When the bundler returns nothing or throws, the preview places the runtime
where the bundled page does (end of head) instead of after the composition's
scripts or not at all; core's placement moves to insertRuntimeTag.
- Every HTML-spec JavaScript MIME type counts as a classic script for merging
and the web-font gate.
- Inlined local files and merged runs are escaped with escapeInlineScriptSource.
* fix: deferred local scripts run late without data: URLs, and authored runtime reads survive
- Local defer/async scripts are inlined in their own tag with the attribute
kept; the font-gate runner (and its old-runtime fallback) runs an inline
classic defer script after the classic scripts, in document order, so a page
policy that allows inline scripts but not data: still runs them.
- stripEmbeddedRuntimeScripts matches the bootstrap attribute and runtime file
names on the tag, not runtime words in an authored script's text.
- The preview applies its runtime on every path, so an adapter page without
one still gets it; the inline escaper writes <!-- as \x3C!--, valid in a
unicode regex.
* fix: a deferred inline script waits for the deferred CDN script before it to load
* fix: an authored script that mentions the runtime marker no longer stops the runtime being added
* fix: only inlined deferred files run late, head ones included, and renders skip a CDN runtime link
* fix: deferred head files run as before, and one selector owns the deferred-file rule

* fix(studio): a first animation in a full-document sub-composition plays
* fix(studio): keep the comment share of the two touched files at their base
* fix(studio): a first animation also plays when <html> carries the composition id
* fix(studio): a root whose id sits on <html> keeps its first animation in <body>
* fix(studio): a composition id on the template tag keeps the first animation inside it
* fix(core): the preview redraw leaves animations after the playhead as the seek drew them
The redraw that re-renders a timeline at its playhead steps silently to just
below it and back. That backward step drew every reversed child that starts
later at its end (a reversed set showed 0.8 where the seek showed 0.2), and the
landing never revisited it. Children starting after the playhead now sit out
both steps. The redraw also puts back the zero-duration state of every
zero-duration child, not only those with callbacks, so two sets on the playhead
keep their authored order on the next seek and a call in an otherwise empty
nested timeline fires as often as without the redraw.
* refactor(core): collect children after the playhead without a per-child array
* fix(core): a scene's opening set disappears when you step back off the scene's start
The redraw's silent round trip left a nested timeline's start-crossing mark
(_zTime) on the wrong side, so the next backward seek skipped the scene and its
opening set stayed drawn. The redraw now restores that mark for every nested
timeline as well as every zero-duration child.
* refactor(core): name the redraw's playhead tolerance instead of commenting it
* fix(core): a pause inside a reversed repeating scene fires once after a redraw
The redraw renders a nested timeline the seek had left inactive, which marks it
active. With its start-crossing mark restored but not its active flag, the next
seek re-ran the scene's pause. The redraw now restores the active flag too.
* fix(core): a held redraw no longer cuts a paused scene short in renders
Holding later children at time scale 0 let GSAP recompute a nested timeline's
duration during the redraw's round trip without them, so a paused
sub-composition kept a shortened length and froze for the rest of the render
(style-5-prod's typed intro). After restoring the time scales, every ancestor
of a held child is marked dirty and the duration is settled again.
* fix(core): the redraw puts back the scene lengths it measured, not re-measures them
Re-settling after the hold recomputed the root's length from whatever was paused
at that moment, which the redraw should not change. The cached lengths of the
held children's ancestors are now snapshotted after the entry settle and
restored in the finally.
* fix(core): composition scripts start after web fonts are ready
A scene script that measures text (offsetHeight, getBoundingClientRect) ran while
the page parsed, often before its web font loaded, so it laid the scene out with
fallback metrics. Renders of the same film differed run to run, and preview could
differ from export.
The compilers now give every body script a type the browser does not run
(text/hf-after-fonts, or +module), through one helper in scriptRuns.ts called
at the end of the bundler, the producer compile and the sub-composition preview.
The Studio motion script is emitted the same way so it still runs after them.
The runtime entry owns the wait: on DOMContentLoaded it forces a layout, waits for
document.fonts.ready or FONT_WAIT_TIMEOUT_MS (5 s), then re-creates each script
in its own place in parser order (classic in order, awaiting src loads; then
module and defer scripts in insertion order), boots as before, and calls the
DOMContentLoaded and load listeners the scripts added. On timeout the scripts
run anyway and runtime_font_wait_timeout names the families still loading.
Scene swaps and the composition loader use the same wait.
* fix(core): a page whose runtime predates the font gate still runs its scripts
A bundle can be served with a runtime loaded from HYPERFRAME_RUNTIME_URL. If that
runtime is older than the font gate, nothing would run the deferred composition
scripts and the film would be blank.
Whenever the marking helper defers scripts, it also puts one small inline script
first in the head. At DOMContentLoaded it runs the deferred scripts in parser
order itself, without waiting for fonts and with a console warning, unless a
runtime has claimed them. The gate's runtime claims them when it loads, before
DOMContentLoaded, so the scripts run exactly once either way.
* fix(studio-server): motion paths animate in Studio preview when gsap loads in the body
The MotionPathPlugin tag Studio inserts after a body gsap script now carries
that script's type, so the runtime runs it right after gsap once fonts are
ready, instead of before gsap exists.
* fix(cli): layout, motion-shot and validate wait for the composition scripts to run
The three commands waited on the timeline registry, which exists as soon as the
runtime file loads, or on a flat sleep. They now wait for the runtime's
render-ready flag through one shared helper, keeping each command's timeout and
proceeding as before when it passes.
* fix(core): a script that wraps addEventListener keeps its wrapper after its scripts run
While composition scripts run, the runtime patches addEventListener to hold
load events that already passed. Putting the original back now happens only if
the patch is still in place, so a library wrapper installed meanwhile survives.
* docs: comments on script timing match scripts that wait for web fonts
The early stub's flush and the player's iframe-load handler described page
scripts as done by DOMContentLoaded and the runtime as ready before load.
Composition scripts now wait for web fonts, so both can come later. Comment-only.
* test(core): pin script order after an external script and the scene swap's font wait
An inline composition script that follows an external one sees its global, and
a scene swap runs the new scene's script only once web fonts are ready.
* docs(producer): the early stub comment names what drains late font-gated work
* fix(studio): motion paths add without a flash when gsap loads after web fonts
Studio preloads MotionPathPlugin on iframe load. A body gsap now runs after web fonts, often after that load, so the preload retries once the runtime reports ready.
* test(cli): pin the runtime wait before each command first samples the page
* fix(studio): the motion path preload stops waiting once the preview runtime has booted
A composition with no global gsap posts ready before the preload runs; the retry listener then never detached and kept each retired preview document alive. It now waits only while the runtime has not booted, and the tests pin the cleanup and the ready filter.
* fix(studio): a preview frame that never boots is not kept alive by the motion path preload
Only the latest preview waits for the ready message of its runtime; a newer load drops the older wait, so a crashed or missing composition frame can be collected.
* style: comments added by the font gate move into names
* test(core): pin the authored floor's direct children, the one-frame media skip and lottie sources
* test(core): pin the loaded-Lottie-library half of the pending rule
* test(core): pin how the runtime resolves a composition's length and size
* refactor(core): move composition length and root size rules into a pure module
* test(core): pin the one-frame timeline floor against a derived length
* fix(core): build and declare the composition-length subpath, reject a non-finite declared length
* fix(studio-server): freeze still appears whole, so a slow extraction cannot break its undo
The freeze route reserved the still's final name with an empty file before
ffmpeg ran. When extraction outlasted the history's quiet time, history
committed that empty file as an outside change, and Cmd+Z then restored a
0-byte PNG. ffmpeg now writes under an atomic temp name the history skips,
and the still is published with createFileAtomically (EEXIST still refuses
a taken name).
* fix(core): a direct exclusive write that fails midway leaves no partial file
Without hard links, createFileAtomically writes the destination directly.
A full disk then left a partial file behind (a corrupt upload or freeze
still); it is now removed, and a name another writer holds is never
touched. Freeze tests: the slow-extraction test leaves a half-written temp
file while history commits, and concurrent extractions meet at a barrier
instead of a real timer.
* fix(core): a quota reported only at close still removes the partial file
* test(core): the direct write closes once and keeps its write error when cleanup fails
* test(core): a failed direct write closes its descriptor exactly once
* refactor(studio-server): freeze names carry what their comments said
* fix(core): a call on the playhead fires once when the preview redraws it
The silent redraw steps off the playhead and back, which re-armed a call sitting exactly on it, so the following seek fired it again. Keep each such call's fired state across the redraw.
* fix(core): a redraw keeps every call's fired state, wherever the call sits
Restoring one field for calls found by position missed a fresh call at 0, calls in repeating or reversed timelines and double-speed scenes. Snapshot ratio and _zTime of every zero-duration callback tween instead.
* fix(studio): load MotionPathPlugin at the composition's own gsap version
* fix(core): list the gsap-cdn subpath where core's exports are generated from
* fix(core): every default gsap URL comes from the one gsap-cdn owner
* fix(core): the gsap a new composition or first tween gets comes from the gsap-cdn owner
* perf(core): a paused Studio drag lets the preview loop sleep until the drag ends
A paused manual-edit gesture marked a reconciling seek as owed, and an owed seek kept the transport ticking every frame for the whole drag: timing reads, a full clip-manifest post every 20 frames that Studio rebuilds its clip list from, and media rebinds every 30. Nothing is owed until the gesture marker clears, and the gesture watch already wakes the loop at that moment, so the loop now parks mid-gesture.
* docs(core): keep the park comment to one line
* fix(core): releasing a paused-media lease wakes the parked loop to stop that media
Release only dropped the lease, so a parked transport kept letting the released element play until an unrelated wake. The lease test passed only because it started the media again after release, which fires a play event.
* test(core): load the runtime once per file so the entry tests' first timeout covers only its own work
* fix(core): a torn-down runtime's pending readiness check no longer touches the next document
* fix(core): a seek onto a tween's start shows that tween, not the earlier one's end
The seek re-render stepped to just below the target and back. A child
starting exactly at the target sits at local time 0 both before and after
that step, so GSAP skips it going forward and an earlier tween on the same
property keeps the frame (fromto edits at the playhead read the from()
end, 35-50 px off). One forced silent render at the target walks every
child forward in authored order instead, so same-time steps still apply in
order.
* style(core): format the seek re-render change
* fix(core): re-render a seek from just above too, not with a forced render
A forced render at the seek time redrew every tween GSAP had ever rendered,
including ones that start later, at their recorded start values: after a
seek past the end, a later tween's start showed early (style-5-prod,
hdr-regression). The re-render now steps silently just above the target,
then just below, then to it. The step up makes a child that starts exactly
at the target cross its start on the way down, so it renders; tweens that
have not started are left as the seek put them, and the last move is still
forward, so same-time steps keep their authored order.
* fix(core): re-cross only the tweens that start at the seek time
The step up past the target (d5c5d797) initialised tweens starting within
the next millisecond, so an overwrite: "auto" tween killed the one before
it, and it crossed a repeatRefresh boundary sitting on the target. The
re-render is back to #4911's step from just below. That step skips a
keyframes or stagger tween already at its start (GSAP passes no start
crossing into the tween's own timeline), so after it each such tween that
starts exactly at the target, at any nesting depth, re-crosses its own
start alone. No other child moves.
* refactor(core): keep the GSAP members the re-cross reads local to the adapter
The shared child type gained members that clash with RuntimeTimelineLike in
the runtime typecheck. The adapter now types them locally and skips any child
that is not a GSAP animation, which also keeps the walk simple.
* fix(core): re-cross only forward-playing tweens, by a microsecond
GSAP skips paused and reversed children when it renders a timeline, so the
re-cross does too: it read a reversed keyframed tween's start instead of its
end and reset a paused one. The step past the start shrinks from 1 ms to
1 us, so it cannot start a stagger's next target or cross a short tween's
repeat.
* fix(core): re-cross only keyframed tweens, by less than GSAP's time step
A 1 us step still reached a stagger target 0.5 us in and a 0.4 us repeat,
both sizes GSAP can represent. The step is now 2e-8: above GSAP's zero
threshold, so the tween leaves its start, but below its 1e-7 time rounding,
so the tween's own timeline does not move. Only keyframed tweens are
re-crossed; a stagger is left as main renders it.
* fix(core): move keyframed tweens across their start before the forward step
Re-crossing a keyframed tween after the timeline's forward render made it
win over a later same-time sibling (a set after it at the same time showed
the keyframe, not the set). The keyframed tweens that start at the target
are now moved across their start during the step from below, and the
timeline's own forward step renders them with every sibling, in authored
order.
The seek path skips its silent re-render on timelines with a zero-duration callback, because that
re-render re-arms the callback and the next forward seek fires it again. The answer was cached per
timeline on the first seek, so a tl.call added later was never seen: the re-render ran and the call
fired twice. The check now reads the timeline's current children on every seek.
* fix(core): music keeps playing smoothly across video cuts in preview
While no Web Audio buffer plays, the preview playhead follows an audio element. It followed the first
one in page order, so a sub-composition whose shots each carry a short sound clip took the playhead
away from the music bed. At every cut the next shot's sound starts late, the playhead waited for it,
the music played on, and media sync then pulled the music back: a jump at each cut. The followed clip
still keeps the playhead; otherwise the in-window clip that runs longest takes it.
* refactor(core): check the followed clip first and drop the clock pick's flag
* fix(core): an ended clip never leads the playhead, and the followed clip keeps it
A bed whose file ends before its authored length no longer wins the pick and leaves the playhead on wall
time. Pins the rule that a longer clip starting late cannot take the playhead from the followed one.
* fix(studio): show each timeline row its own layer instead of a grey bar
A row got a frame only if it spanned under 92% of the film and its id did not
look like a backdrop; every other row drew a plain grey bar. Every element row
now gets its frame, and the capture fades the row element's siblings first, so
the frame shows that layer and not the whole film. Studio's dev server and the
CLI share one capture helper; Studio's own copy is gone.
* fix(studio): read timeline rows from any realm so each keeps its selector
* refactor(studio-server): always isolate the element in a thumbnail clip
* fix(cli): undo a thumbnail's isolation before its page takes the next capture
* chore(core): generate the dom-realm export and trim thumbnail clip comments
* fix(studio-server): restore sibling opacity after a clip, hash selectors in cache keys
* fix(studio-server): keep faded siblings in a page-owned list so restore is exact
* feat(studio): draw a text layer row as its own live text instead of a captured picture
* refactor(studio): move timeline text reading into its own module
* fix(studio): keep text rows readable and current, and leave painted layers as pictures
* fix(studio): refresh a canvas-edited text row by its own identity and source file
* fix(studio): refresh a canvas-edited text row known only by its data-hf-id
* fix(core): render tl.set steps on the frame they land on
The runtime re-rendered a seek by stepping just past the target and back.
Arriving backwards, GSAP applies same-time zero-duration steps in reverse,
so a film that hides every frame then shows one, on its frame grid, lost
that layer on every step: in renders, previews and thumbnails. It also
fired a tl.call on the target time again on each repeated seek. Both seek
paths now re-render from just below the target, silently.
* test(core): expect the seek re-render to arrive from below
* test(core): pin the seek re-render from below in the runtime seek script
* fix(core): keep re-rendering a seek to 0 from above
* test(producer): rebase style-4-prod on caption frames that render forward
* fix: hide console windows spawned by ffmpeg and nvidia-smi on Windows
Node's `windowsHide` defaults to false, so every child process that is a
console application pops a window on the user's desktop. During a render
or a regression run that is a stream of black windows stealing focus.
The repo already sets `windowsHide: true` across cli, studio-server and
most of engine; these were the remaining gaps, all on paths that run
during a normal render:
- core/mediaGradeAnalyzer: ffprobe + ffmpeg, once per analyzed media file
- engine/browserManager: `nvidia-smi` VRAM probe. This one goes through a
shell (`execSync`), so it flashes a cmd.exe window even on machines with
no NVIDIA GPU, where the command exists only to fail
- producer: the regression harness ffmpeg runner, PSNR/audio comparison
helpers, fixture synthesis, and the ffprobe call in audioPadTrim
No behavior change on POSIX, where the flag is ignored.

* fix(producer): escape PSNR stats_file for ffmpeg's two-pass filtergraph parse
An ffmpeg filtergraph argument is unescaped twice: once when the graph is
split into filters and their options, then again when the option value is
read. `psnrAtFrames` escaped `\` and `:` a single time, which only survives
the first pass.
On POSIX that is invisible, because mkdtemp under tmpdir() produces neither
character. On Windows the stats path is always `C:\Users\...`, so it reaches
the option parser with a bare `:`, which starts a new option and fails the
whole graph:
[AVFilterGraph] No option name near '\Users\...\psnr.log'
Error parsing filterchain '[rv][gv]psnr=...:stats_file=C\:\Users\...'
Every suite that got as far as quality validation died there, so a Windows
regression run reported 0 passes with only 2 genuine compilation failures.
Escaping for both passes fixes it and stays a no-op on POSIX.

relinkSplitHalves reminted the right half's sync origin even when only one
member of an unlinked source pair was cut, so the uncut partner kept the old
origin and the new half lost its badge. The origin is now reminted only when
both the video and the audio were cut.
Slip into Sync wrote data-media-start whenever it existed, but playback
reads data-playback-start first, so a clip carrying both never moved. The
link timing reader now uses playback's precedence and the slip writes the
attribute that wins; lint compares the same field. A sync partner is also
looked up only in the clip's own composition (core) or source file (Studio).

* refactor(lint): drop the rule-list comment for the linked clip rules
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(sdk,lint): keep a link group inside its own composition
Link ids are minted per file, so lk-1 is normal in the root and in a child
composition. The SDK's linked-timing query descended into nested hosts and
addressed every match with the initiating scope, so moving a root clip moved
the child's pair too; lint grouped them into one drifting group. Both now
group only members of the same composition scope.

* fix(studio): match linked media by full asset path, scope links, keep hidden sound silent
Merge and Link compared only a lowercased basename, so assets/one/talk.mp4
and assets/two/talk.mp4 enabled a destructive Merge. Clips now compare the
src resolved against each clip's own source file, and Merge re-checks the
two srcs in the source before it runs. Link membership in the timeline
(linked members, gesture expansion, unlink orphans) is scoped to a source
file. Detach and the keep-sound cutout carry a hidden video's data-hidden
to its audio, and Merge refuses when only one member is hidden.

* refactor(studio): move the timeline move-edits handler into its adapter
App.tsx sat at 600 lines on this layer and 602 once merged with main.
useTimelineMoveEditsHandler now lives beside persistTimelineMoveEditsAtomically,
same callback and dependencies, bringing App.tsx to 592.

* fix(sdk,studio,lint): keep link groups inside inline compositions
A link group now stays inside the nearest data-composition-id or
data-composition-file ancestor. The SDK used to recognise only file hosts,
and Studio compared only sourceFile, so an inline child composition that
reused a link id was edited together with the root group. core/media-link
linkScopeOf is the shared rule for the SDK and Studio. Lint cannot import
core, so it uses the same two attributes directly. Studio rows record their
compositionScope, and link and merge refuse pairs that cross it.

* fix(sdk): refuse a link edit whose partner address names another clip
A partner addressed in the caller's scope can resolve to a different element
when an inline composition reuses a root clip's data-hf-id. setTiming now
checks that each partner's address resolves back to that partner and throws
before mutating when it does not, instead of editing the root clip.

* fix(studio): a remote media url keeps its query when matching an asset
Two different videos at one remote path with different queries were treated as
the same file, so Merge could delete the audio and use the wrong video's
sound. Project-local srcs still drop query and hash.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
* fix(studio): keep a remote url's query exactly as written when matching assets
Decoding the whole url folded %26 into & so two different media urls matched.
Decode only the path; the query is compared as authored.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
* fix(studio): compare a remote url as serialized, decode only local paths
A remote pathname with an encoded reserved character (%3F) matched the same
path with a literal ?, though they can return different media. Remote urls
keep origin, path and query exactly; local srcs are still decoded and
stripped of query and hash.

* feat(studio): draw a waveform strip under video clips that carry sound
An audible video keeps its thumbnails and gains the audio waveform along the bottom
38% of the clip (also when thumbnails are off); muted and silent video are unchanged.
The waveform route already decodes video audio; a test now proves it on an mp4.

* feat(studio): mark where each clip redlines on its waveform
studio-server computes an absolute per-50ms sample-peak map once per media file
(native channels, cached by size+mtime next to the waveform cache); the timeline
paints red marks where the source at the clip's own volume reaches -1 dBFS and
names the loudest point.

* feat(studio): let a video with sound be the beat source
Studio's isMusicSourceElement accepts an audible, unmuted video for the music track
and the beat fallback (lane zoning unchanged); core findMusicAudioSrc accepts
<video data-has-audio="true"> without muted; the beats CLI message mentions video.

* fix(studio): decode each peak map once and never offer Duck on a carve source
Concurrent peak requests for one file share a single ffmpeg decode; Duck under voice
is withheld on a clip another bed already carves against.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(studio-server): decode the same audio stream the peak map probes
The channel probe read stream a:0 while the decode left stream choice to
ffmpeg, which picks a later stereo stream over a mono first one; every frame
was then read at the wrong width, doubling the bins and taking the other
stream's level. Both commands now select a:0, and the cache key moves to
peaks-v2 so maps built from the wrong stream are rebuilt.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(studio-server): reject a peak map whose decode exits nonzero
A decode that emits some samples and then fails no longer resolves as a

* feat(studio-server): add freeze-frame file mutation
Extracts the frame under the playhead with ffmpeg (media time honours
data-media-start, playback rate and a rate lane) into assets/freeze/, then in
one write splits the video, inserts a 2 s <img> still with the video's box
styles, shifts the rest of the track and splits a data-link partner.

freeze-frame mutation and records its before/after as one undo step.
onFreezeFrame is threaded through the timeline edit callbacks.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(studio-server): keep the freeze still inside assets/freeze
The clip id from the project HTML went straight into ffmpeg's -y output
path, so an id with ../ segments wrote outside the project. The id is now
reduced to one safe filename component, the output is pinned inside
assets/freeze before extraction, and the still's src is built from that
name rather than from a filesystem path.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(studio-server): give every freeze still its own immutable name
Two clip ids that sanitise alike (a.b / a_b), ids sharing an 80-character
prefix, or a second freeze of one clip at the same playhead all produced the
same still path, and ffmpeg's -y replaced the first still's pixels. The name
now carries a hash of the raw id and a per-extraction token, the route
refuses a name that already exists, and ffmpeg runs with -n so it can never
overwrite. The freeze media time reads data-playback-start before
data-media-start, as playback does.

* feat(runtime): route processed audible videos through web audio in preview
An audible <video> joins the Web Audio schedule, hidden-toggle and
group-capture passes when it needs a gain el.volume cannot express: a
boost above unity, an fx chain, automation, or an audio group. A plain
audible video at unity stays on native output. The clock master stays
audio-only; a video whose capture fails stays on native output (never
decoded, never failed closed).

* fix(runtime): capture ramped clips so a group's bus carries them in preview
A rate lane skipped Web Audio entirely, so a ramped video or audio clip in a
group played native output without the group's fader, mute or FX while the
export applied them. Only the decoded-buffer fallback cannot follow a rate
curve; the media-element capture can, so the skip now guards that fallback.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(studio): show meters only for videos Web Audio carries
A plain audible video at unity stays on native output, which the meters
cannot read, so it no longer advertises them. The runtime's join rule and the
meter gate now share audibleVideoNeedsWebAudio (core/audible-video).

* fix(cli): init from-file a-roll is timed, muted strip is attribute-exact
The from-file a-roll video gets data-start="0" so a scaffold lints clean, and
the orphaned audio-only slot comment is dropped. setVideoAudio now walks the
tag attribute by attribute, so a class value containing the word muted
survives. The ffprobe-missing warning says the video is assumed to have sound
and how to switch to muted, and DEFAULT_META notes the failure surfaces at
render until lint support lands.

* fix(studio): keep has-audio in step with the muted toggle, test cutout confirm
Muting a video now clears has-audio and unmuting sets it to true, in both the
Design and flat media panels, matching the Has audio track toggle. Audio
elements are unchanged. Adds coverage for both panels plus the cutout
window.confirm guard: declined leaves src alone, accepted swaps src and mutes,
a silent video never prompts.

* docs: video_missing_muted rule text, silent-footage notes, consistent audible examples
lint.mdx and cli.mdx describe the current video_missing_muted rule instead of
the retired unmuted-video wording. The editing recipes say how to adapt for
silent footage and require the outgoing clip's sound to end at a J-cut. The
Remotion media example shows the audible mapping consistently, data-attributes
states that has-audio is required unless muted, and the hairline frame note no
longer claims the video is muted.

Muted and Has audio track commit one batched write (one persist, one

false, probe failed -> absent. Remove background on an audible video
inserts a linked sibling <audio> with the original sound in the same
write, replacing the drop-the-sound confirm.

videos.
