* fix(studio): a snap the saved clip would miss no longer moves it

* 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.

* fix(studio): a fade's draft clears with its own save and grow drags never shrink it
* fix(studio): saved fades reach the timeline store so the handle stays where it was dropped
* fix(studio): a fade longer than its clip starts a drag or key from the clip's end
* fix(studio): fade comments state the rule, not its history
* fix(studio): fade handles show a real tooltip and a 24 px target
A sound clip's fade-in and fade-out dots now open Studio's tooltip
("Fade in 0.3 s") instead of a native title the clip's own title
competed with, take a 24 px hit box, and paint an opaque white dot that
reads on the audio clip in both timeline themes.
* fix(studio): fade handles sit at the clip's top corners, above its content
The fade-in and fade-out dots now pin to the clip's top-left and top-right
corners instead of the end of each fade, paint above the waveform and
thumbnail layers, and share a short clip's width without overlapping. The
fade ramps are clipped to the clip's rounded corners, and the tooltip
uses the same seconds format as the slider's value text.
* fix(studio): fade dots keep their 10 px size on a very narrow clip
On a clip narrower than two fade hit boxes the flex row squeezed each dot
below 10 px. The dot no longer shrinks and no longer takes the pointer, a
browser check measures its box on a 0.1 s clip in CI, and two drag test
comments now describe the corner handles.
* fix(studio): the Escape key cancels a fade drag wherever keyboard focus is
A press on a fade handle never focuses it, so Escape only reached the
handle's own key handler when something else had focused it, and the
release then saved the dragged fade. The drag now listens for Escape on
the window for as long as it lasts, restores the fade and saves nothing.
* test(studio): trim the fade handle browser check header to what the code cannot say
* test(studio): gate edit accuracy against the base branch baseline
Work in progress: the ratchet and its tests; the CI job follows.
* test(studio): run the edit accuracy gate in CI across eight shards
Shares the built CLI from the Build job, re-runs twice each case that passes on the base branch and failed, and posts one sticky comment from the gate job.
* test(studio): mark the ratchet accuracy check as intentionally branchy for fallow
* test(studio): confirm newly passing edit accuracy cases 2 of 3 before banking them
The shards re-ran only regressions, so one lucky pass of a base-failing case failed the gate as unbanked and was never listed as unstable. Every case whose verdict differs from the base branch, either way, is now re-run twice and judged 2 of 3. A render error fails the gate like an unsettled snapshot, a malformed baseline.json fails the job instead of reading as empty, and the header is 3 lines.
* ci(studio): run the edit accuracy gate for every package the bench builds or imports
* ci(studio): also run the edit accuracy gate for lint, sdk and the Studio and CLI build inputs
* ci(studio): run the edit accuracy gate when a bench package's manifest or exports change
* test(studio): bank the 120 edit accuracy cases that sub-pixel dragging now passes
* ci: install a pinned static ffmpeg on linux instead of apt
* ci: run the jobs that use a shared action when that action changes
* ci: drop the ffmpeg cache so the install is bounded by the download alone
* ci: cap ffmpeg download retries so a Retry-After header cannot stretch the install
* test(producer): run the late-host pip and dogs-captions fixtures in CI
The pip fixture wrote its video start in root time without the global
basis marker that PR 3732 made the contract, so it rendered the empty
host. Mark it global and schedule both fixtures that never ran in CI.
* ci(producer): split regression fixtures across nine shards
dogs-captions runs about eight minutes on its own; a ninth shard keeps
the other shards near their previous wall time.
* ci(producer): run dogs-captions in a nightly regression job instead of on every PR
* ci(producer): base the dogs-captions timing and nightly reason on two CI runs
* feat(plugins): ship portable agent bundles and installation guides
* fix(plugins): align new manifests with current release
* test(plugins): split caption fixture setup and cleanup
* test(plugins): pass render fixture path as an argument

* style(cli): format the test home check
* test(cli): the skills test lane also runs with a home folder of its own
* style(cli): format the test home check
* ci: the test reachability map follows the skills lane's new command
* fix(media-use): tests never write into the person's media library
* fix(media-use): guard the media home only in this repo's test runs
* test(media-use): probe the media home from a plain child process
* fix(media-use): keep miss logging best-effort when home is unresolvable
* test(media-use): miss logging survives an unresolvable media home
* docs(media-use): describe the media library without naming an app
* chore(media-use): refresh the skills manifest hash
* ci: stop running CodeQL on merge queue groups, where its upload races the merge
The code scanning rule does not apply to merge queue groups, and the queue deletes
a group ref when it merges, so the upload failed on about half the groups.
Pull requests and pushes to main keep scanning.
* ci: catch merge_group in any trigger form and say the upload race is intermittent
* ci(studio): bank the open-journey counts after #4401 and allow a reasoned raise
* fix(studio): render a missing preview poster whichever of the 404 and the live frame comes first
* ci(studio): gate Studio open and timeline scroll on work counts that only go down
Beside the timeline viewport gate's ms budgets, count the work two Studio journeys do and hold
each count under a checked-in ceiling in perf-ceilings.json: thumbnail renders, page loads and
requests for opening a 12-scene film, and React commits, style recalcs and layouts per scroll
tick. Counts repeat exactly run to run, so a rise names the work that grew.
* ci(studio): hold style recalcs per scroll tick at the CI runner's count
* ci(studio): gate the median scroll run and list which thumbnails rendered
* ci(studio): set work-count ceilings from the CI runner's counts on main
* ci(studio): fail the open count loudly when Studio never starts
* ci(studio): fail a work-count gate that measured nothing
* ci(studio): a scroll counter missing from any measured run reads as not measured
* ci(studio): split the perf ratchet's CLI and page counters into small steps, and let its unit test count
* ci(studio): count scroll work in an untimed pass and commit the open fixture's scenes
* ci(studio): gate only the open journey's counts; scroll counts follow runner speed
* ci(studio): fail a dropped journey and an unreadable base in the work-count ratchet
* ci(studio): split the ratchet's checks into small functions
* ci: editing a PR's text no longer cancels its running checks
CI, regression and Windows render re-run on pull_request edited (for base changes) with cancel-in-progress, so a body or title edit cancelled the running checks and the fail-closed Test aggregator went red on the cancelled run. Only a push or a base change cancels now; a text edit queues behind the running run.
* test(ci): read the workflows folder by path, not as a module URL
Fallow treated new URL('../.github/workflows/', import.meta.url) as an unresolvable import. Use import.meta.dirname and join, as scripts/check-skill-mirror.mjs does.
* fix(media-use): remove clicks and ~25ms gaps at every transcript-cut splice
transcript-cut extracts each kept range to its own final-codec file, then
concat-copies them. That produces two audible artifacts at every cut:
1. No boundary fades. Concat splices raw segment edges together, so the
waveform steps discontinuously and each cut clicks.
2. Encoder priming silence. Each segment is encoded to AAC independently,
so the encoder pads every one with priming samples. Stream-copy concat
bakes that padding in as a silent gap at each splice. Measured 24.4 ms
and 24.1 ms at the two splices of a three-range cut. It accumulates:
the nth splice lands roughly 25n ms late, so splice positions drift
away from the sum of the preceding segment durations.
The second survives the first -- adding fades alone leaves the gap.
Fix: intermediates carry PCM (.mkv for video, .wav for audio-only) instead
of the final codec, so audio is encoded exactly once, at concat. Boundary
fades of 30 ms are applied per segment, scaled down on segments shorter
than 4x the ramp and skipped on degenerate ones.
Measured on the same three-range cut, widest run of digital silence at
each splice:
before 24.4 ms / 24.1 ms
after 0.1 ms / 0.1 ms
--copy is unchanged: stream copy cannot filter, so it keeps producing
final-codec segments and a copy concat. Audio-only output is byte-identical
in duration before and after. scripts/lib test suite: 34/35, the one
failure (lut-preset-provider) pre-exists on main and is unrelated.

* chore(skills): regenerate manifest for media-use
* fix(media-use): honor the fadeIn/fadeOut flags fadeFilterFor was passed
The caller already computed {fadeIn, fadeOut} per segment, but
fadeFilterFor still took one parameter and always emitted both
afade ramps -- so a single kept segment (no splice at all) and every
segment's true start/end got faded regardless. Extracted the pure
function into lib/transcriptCutFade.mjs, made it honor both flags,
and added its first unit test: first/middle/last/single-segment
filter strings, no ffmpeg needed, fails against the previous version.
Also installs ffmpeg in the Test: skills CI job (same action the
Producer job uses), so transcript-cut.test.mjs's real-tone RED/GREEN
proof runs in CI instead of skipping silently for lack of the binary.
* fix(media-use): fix the packed-CLI import and lint on transcript-cut.mjs
build-copy.mjs replaces dist/skills/media-use/scripts/lib with a copy
of packages/cli/src/media-use/lib, so transcriptCutFade.mjs needed a
byte-identical twin there (and in MEDIA_USE_COPY_NAMES) or the packed
CLI's transcript-cut.mjs imported a file that no longer existed.
Moved its test alongside, matching every other lib helper's tests.
Also drops three redundant Boolean(args.copy) wrappers (a ternary
condition already coerces) that oxlint's no-extra-boolean-cast
flagged.
* style(media-use): reflow the shortened ext ternary to oxfmt's shape
Dropping the Boolean() wrapper shortened the line enough that oxfmt
0.41 now collapses the ternary onto one line; format:check was failing
on the stale multi-line version.
