* fix(studio-server): history never files a hidden file as a change

* fix(studio-server): an older log's hidden-file entry no longer stalls Undo
* fix(studio-server): an older log's emptied Undo still keeps its target undone

* refactor(studio-server): history's hidden-path rule says itself in names, not comments
* 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
* refactor(studio): the auto-id write posts through the one patch-element client
* test(studio): pin the auto-id write's saves, refusals and unsafe targets
* test(studio): pin the auto-id write's plain refusal and missing changed flag
* test(studio): the auto-id write needs a toast handler and sends the write token
* refactor(studio): one request for every GSAP mutation write
* fix(studio): a refused id write no longer leaves the id on the previewed element
* style(studio): drop the two comments the names already carry
* fix(studio): keep minting the id on the element so overlapping adds never share one
* fix(studio): an id the file already holds counts as saved, and no project leaves no id
* fix(studio): the server picks an added effect's element id, so ids never repeat
The browser minted the id from the live preview and rolled it back when the
write failed. A reply lost after the id was saved left the file holding an id
the preview had dropped, so the next add on a sibling wrote the same id again;
and a refused add could strip the id an overlapping saved add had just given
the same element.
A new patch-element op, ensure-id, keeps the element's id or makes the proposed
one unique in the file, and every patch-element reply names the element's id.
Studio sets the id on the preview only from that reply, so there is nothing to
roll back. nextUniqueId moves to sourceMutation as the one owner (split and
duplicate already used it).
* test(studio): pin the gsap write token and the refused-write toast

* fix(studio): count an id written right after a quote or slash as taken
* fix(studio): a quote-ended string no longer hides another file's id
* 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

* fix(studio): an edit on a GSAP-animated layer writes its value at the playhead into the file's tween
* fix(studio): undo pressed while an edit saves undoes that edit, not one started after the key
* fix(studio): an edit stays saved when the history reply after it cannot be read
* feat(studio): export ColorField and GradientField; a session style commit takes a map
* refactor(studio): name the map form instead of commenting it
* feat(studio): a host can move layers by exact film px, one undo per call
handleDomGroupMoveBy(moves) on useDomEditSession and DomEditValue moves each
selection by its delta in composition px, for Desktop's align and distribute.
It reuses the group drag's own path: a drag member per element (press-time
route, measured offset map), the delta carried to screen px through the
preview frames, then handleGsapAwareGroupPathOffsetCommit, so one shared
coalesce key gives one undo entry and GSAP members take the GSAP write.
A member that can't move refuses the call before anything is written; the
refusal rejects with its reason and shows no Studio toast (the group commit
takes refusalToast: false; telemetry stays). Zero deltas are skipped.
Tests: a pre-offset element and one under a half-scale parent move by exactly
{10,0} and {0,-5} under one group key; a half-scale parent with a 30 deg
rotated ancestor lands within the 0.001 px a translate is written with; a
GSAP member goes through the GSAP write; three refusal kinds write nothing,
leave the boxes where they were, show no toast and leave no gesture mark,
while a canvas group drag still toasts; the session hands the call to the
group commit with refusalToast: false. Each mutation (no frame mapping, no
zero skip, no restore, no teardown, no capability check, toast on refusal)
fails at least one of them.
* fix(studio): an outside change during a drag waits for the drop to show
While a gesture mark is live in the preview, refreshPlayer takes the shadow load instead of
swapping scenes in place. A swap replaced the node under the pointer mid-drag; the shadow load
is then held by the existing gesture hold and, if the drop saved, reloaded fresh by the stale
rule, so this adds no second "released" signal.
Test: an outside change during a live drag on a preview that can swap scenes leaves the dragged
node in place, shows nothing under the pointer, and after the drop loads fresh with the dropped
position. It fails on the parent without the condition ("swapped under the pointer").
Cost case, measured in a real headless preview on the edit-accuracy bench's per-frame teleport
check. Every GSAP instant patch was forced to miss and fall back to reloadPreview during its own
commit; move and rotate of a held element (gsap.set and tl.set holds), px and xPercent
placement, r0 and r30, root and nested, at 100%:
- The gesture mark was live when the fallback asked for the reload, but had always ended by the
time refreshPlayer ran (refreshKey is consumed in an effect after the commit settles). So the
new condition never fired there: root previews offer no scene swap and load shadow on both
builds, and nested previews swap on both builds.
- Worst post-release frame offset, 32 cases on this build and 32 on the parent: 0.00 px over
76-106 frames each (release to settle). No frame was off by more than 0.5 px.
- Sensitivity: a 3 px nudge injected 50 ms after the fallback reads back as 3.00 px.

* fix(studio): a rotate on a tween that turns another axis holds its angle and never turns early
* fix(studio): plan every group member before the first write so one refusal moves none
A group drag or nudge preflighted each member against the move refusal rule only. The value-at-playhead planner ran later, in the commit loop, after earlier members were already flushed to disk, so a tween with extras, eased keyframes or an unknown ease left the group half moved.
The group preflight now runs the commit's own route and keyframe plan for every member with its real offset, so any refusal refuses the whole group with nothing written and one toast attributed to the refusing member. The plan is not reused in the commit: earlier members' writes change the file under it, so each member re-plans against the fresh tween, from the same planValueEdit.

* perf(studio): keep timeline bulk actions under a second, hand-move at most 3 clips
Dragging or keyboard-moving a selection of 4 or more clips is refused with a
toast pointing at the prompt box; 1 to 3 clips move as before.
Root causes of the multi-second waits on large projects:
- every selected clip fired its own source-existence probe; they now leave as
one request per file
- a timeline delete sent one request per clip, each re-parsing the file; it is
now one request that parses once
- each click on a clip from another file re-fetched GSAP data for every
composition; covered files are kept and unchanged files answer 304
- any root index.html write re-captured every composition thumbnail; only a
root head edit does now, since a scene page borrows nothing else from it
Adds timeline-bulk-actions.mjs, a browser benchmark of select-all, move 3 and
delete-all on a real project.
* chore(studio): trim the bulk benchmark header to the comment limit
* refactor(studio): tidy the bulk-action fixes after review
Root head memo is keyed by the root file's content so every subscriber of one write gets one answer, and a thumbnail request can no longer overwrite it. The GSAP read reuses the shared content version as its ETag.
* fix(studio): keep a head edit's thumbnail refresh when a later write replaces it
File changes coalesce to the newest while a drain is in flight, so the affected-composition lists are merged instead of replaced. A failed GSAP read stays unloaded and is retried, and the GSAP read's ETag is salted with the parser version.
* feat(studio): cap hand-resizing a multi-selection at 3 clips like moving
Dragging a resize edge with 4 or more clips selected is refused with the same toast as a move; the rule is one constant and one helper shared by pointer move, pointer resize and keyboard pickup.
* fix(studio): keep a head edit's thumbnail refresh through a replaced conflict
A newer blocked change replaces the held one, so it now inherits the thumbnails the held one owed.
* fix(studio): keep a held head edit's thumbnail refresh when a later write saves cleanly
The clean-save path and the failed-cleanup path now merge the held blocked change's affected compositions, and the blocked-state merge runs inside the state update so two conflicts in one tick cannot lose the first.
* chore(studio): keep useTimelineClipDrag under the 600-line cap
* feat(studio): cap by the clips an edit would change, and cut the added comments
The 3-clip rule counts the clips a move or trim would write to: a locked clip swept into a move stays put, and a trim some member cannot take edits only the grabbed clip. Comment share is back at or under the base in every changed file.

* 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(cli): hide console windows on Windows for background/detached spawns
Add windowsHide: true to 8 spawn/execFile call sites that were missing
it: ffprobe/ffmpeg probes in the producer and engine packages, the
telemetry exit-flush and studio dev-server spawns, and the browser-open
and background-preview detached launches in the CLI.
previewLifecycle.ts's spawnDetachedPreview redirects stdout/stderr to a
raw log-file descriptor; libuv only adds Windows' CREATE_NO_WINDOW flag
when no stdio slot inherits a raw handle, so windowsHide alone does not
fully suppress a console flash there (documented inline) — it's still
added for consistency and because it correctly sets the process's
show-window state regardless.
Co-Authored-By: Miguel Ángel <miguel.sierra@heygen.com>
* fix(cli): correct windowsHide flash-risk claims and add missing dev-server spawn tests
- The previewLifecycle.ts comment (and its mirrored test comment)
overstated the residual console-flash risk on the detached background
preview spawn: DETACHED_PROCESS already leaves that child without a
console regardless of whether CREATE_NO_WINDOW gets applied.
- Add the two missing regression tests for preview.ts's runDevMode and
runLocalStudioMode spawns, exporting both for test access.
- Drop an unused export in audioPadTrim.ts flagged by the repo's dead-code
gate; the constant is only ever used within its own file.

* fix(engine): hide console window for the drawElement self-verify PSNR comparison
psnr.ts's execFile call runs in-process inside the Studio server's render
path (parallelCoordinator.ts's drawElement disk self-verify), so a render
started from Studio's UI under a detached preview hits this call from a
console-less parent — the same flash case the other windowsHide sites in
this PR already cover. psnrFilterAvailability.ts's probe is on the same
in-process render path and already had the flag.
Co-Authored-By: Miguel Ángel <miguel.sierra@heygen.com>
* fix(cli): keep only the spawn sites main still misses and leave browser windows visible
windowsHide maps to libuv UV_PROCESS_WINDOWS_HIDE, which also starts GUI apps with SW_HIDE,
so the detached browser launch must not set it. The background preview child already has
no console (DETACHED_PROCESS with inherited log fds), so its flag was a no-op. The
telemetry, psnr and audioPadTrim sites shipped on main via #3839 and #4604.
* fix(cli): stop the studio dev server when the terminal closes
With windowsHide the dev server runs in its own hidden console on Windows, so closing the terminal
only signals the wrapper (SIGHUP). Handle it like SIGINT and SIGTERM and kill the process tree.
* fix(studio-server): hide the console window for loudness measurement
The background preview has no console, so its ffmpeg loudness run opened a visible window on Windows.
* refactor(cli): drop the comment on the studio shutdown signals

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(core,sdk): keep a one-sided cut's sync origin and slip the in-point playback reads
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).

* fix(core,studio): find sync partners inside the link scope
findSyncPartner and Studio's syncPartnerOf now scope by the same rule as
link groups: the nearest data-composition-id or data-composition-file
ancestor, plus the row's compositionScope in Studio. An origin reused in a
file host or an inline composition no longer pairs across it.

Split and delete fan out to link partners. Alt drag/trim edits one member
and unlinks it. onLinkEdit runs unlink, link, detach and merge as one undo
step each. Single-clip timing edits of a linked clip skip the SDK path so
its linked default cannot move the partner behind the store.

* 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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* 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

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): latch a CLIP light on the master meter at the export ceiling

* 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

* 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
complete map, so /peaks cannot cache a truncated clipping map.

* feat(studio-server): share loudness measurement with an absolute target and video support
normalize-audio moves its measure/plan code into @hyperframes/studio-server/loudness,

* feat(producer): report how far the true-peak limiter lowered the export
The AAC true-peak pass now returns its attenuation; the render logs "Audio lowered

servers carry in the complete SSE event and the /renders record. Also exports
useAudioMetersVisible from @hyperframes/studio for hosts.

* fix(studio): refuse to normalize a volume-automated clip and honour save outcomes
A volume lane owns the clip's gain in preview and render, so writing

outcome, stop at the first failed or refused write and report it.

styles, shifts the rest of the track and splits a data-link partner.

* 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.

cache keys on the encoded URL so ids with ':' can't collide.
