The error handler called cleanup(), which sets video.src = "" and calls
load(). Clearing src itself fires another error event, re-entering the
handler at event-loop speed — every pass allocating a React update via
setFailed(true). The seeked path triggers the same loop: its cleanup
provokes the synthetic error right after a successful frame extract.
Detach the error listener inside cleanup() and ignore the synthetic
empty-src error. Instrumentation on a real session measured ~475k src
assignments/second and ~8.6 MB/s of update allocations before the fix.

* fix(cli): stop the preview server's browser when the server exits
Cancel in-flight renders and thumbnail launches before draining the
browser pool on shutdown, instead of only closing whatever browser was
already registered. A render whose Chrome died from the shutdown signal
itself was being misclassified as a transient failure and retried with a
fresh, untracked browser that outlived the process. Reject new render and
thumbnail requests once shutdown has begun, and await an in-flight
thumbnail launch before closing it.
* fix(cli): close preview browsers before a hung render, keep SIGINT armed
shutdown() awaited renders before closing browsers, so a render slower
than preview.ts 3s exit watchdog left Chrome running when it fired.
Close the thumbnail browser and drain the pool concurrently with, not
after, the render wait, and bound the wait under that watchdog.
A second Ctrl+C/SIGTERM during shutdown removed the one-shot signal
handlers, so it hit the OS default and killed the process before
cleanup ran. Use persistent handlers guarded by the existing
shuttingDown flag instead.
Also: getThumbnailBrowser could still hand a live lease to a request
that lands after shuttingDown flips true; trim a comment over budget;
replace a fixed-sleep test race with a drain-signal barrier.
* fix(engine): make browser pool shutdown terminal, not just draining
drain() resets its drainPromise to null once it settles, so acquire()
only waits for an in-flight drain -- a render still unwinding after
shutdown could relaunch Chrome the instant that drain resolved
(probeStage.ts:449-465 has exactly this gap between an abort check
and a later acquireBrowser call). No non-shutdown caller reuses the
pool after draining it (checked every drainBrowserPool()/drain()
call site), but added a separate terminal close() rather than
changing drain()'s own semantics, so a future reuse caller stays
safe by default.
BrowserLeasePool.close() sets a permanent closed flag before
draining, and acquire() checks it both before and after its one
await point, so a request already mid-await when close() lands still
sees it once that await resolves. studioServer's shutdown() now
calls the new closeBrowserPool() instead of drainBrowserPool().
Also bounds drain()'s own wait: a close() that hangs past 1s now
gets escalated to a force-close instead of blocking the caller
indefinitely, keeping total shutdown time under preview.ts's 3s exit
watchdog alongside the existing render-wait bound.
* fix(engine): trim closeBrowserPool JSDoc to house comment length
* fix(server): contain static file requests within their served roots
Static asset handlers joined the raw request path onto their root
directory without checking where it landed. Hono decodes percent
escapes while routing, so an encoded backslash (%5c) arrives as a real
separator on Windows and dot segments arrive already collapsed —
"/assets/..%5c..%5csecret" and "/%2e%2e%2fsecret" could read files
above the studio bundle root (embedded Studio server) and above
compiledDir/projectDir (engine render file server). Browsers never
request those shapes, but anything that can reach the bound port can:
raw local clients, LAN peers when the preview binds 0.0.0.0, and a
shared-machine process hitting the render server.
Both handlers now resolve the request path first and refuse anything
that collapses outside its root, using the same lexical containment
the preview asset route already applies — bundle/project assets behind
symlinked directories keep being served, only dot-segment escapes are
rejected. Route-level pathSafety tests pin the behavior in both
packages, including the Windows backslash shape and the
symlinked-asset cases from the descriptor-pinning regressions.
Validated: new containment suites fail on the prior handlers (200 +
marker file content served from outside the root) and pass with the
guards; cli server (140), engine services (1024+, matching the main
baseline incl. pre-existing browserManager failures), typecheck,
oxlint, oxfmt and the full workspace build all clean.
* fix: close fallow audit findings, prove containment cross-platform
Fallow audit (health/complexity): createFileServer's request handler
exceeded the CRAP-score threshold once the new containment checks were
added. Extracted resolveContainedPaths, a small pure function that
resolves and validates both roots, cutting the handler's own branching
back down.
Fallow audit (duplication): the new pathSafety test files copied their
temp-root/studioDir setup and teardown from the existing staticAssets
test wholesale. Extracted the shared parts into
studioServerTestFixture.ts (makeStudioServerRoot, writeStudioIndexHtml,
cleanupStudioServerRoot); only the per-file vi.mock("node:path", ...)
call stays duplicated, since Vitest requires it declared statically in
each test file and it cannot be moved behind a shared function -- that
one block keeps a narrow, targeted ignore comment instead of a
file-wide one.
Security claim: isWithinProjectRoot's %5c-decoded-backslash escape is
real, but only on Windows -- POSIX never treats a literal backslash as
a separator, and Hono leaves %2f undecoded in c.req.path, so none of
the new tests' encoded-traversal payloads produce an actual escape on
Linux (verified empirically: they pass identically with the fix
reverted). isWithinProjectRoot now takes an optional path-module
override (defaulting to the host's native node:path, so every existing
caller is unchanged) so its win32 and posix branches can be unit
tested directly from one OS, the same pattern already used by
producer/fileServer.ts's isPathInside. New tests cover a backslash
traversal, a mixed backslash/forward-slash traversal, and a
drive-letter path escaping the root under path.win32, plus the
existing posix case -- confirmed each one fails when the check is
removed. The HTTP-level tests stay as-is: real regression coverage for
them comes from the windows-latest CI job, which runs both new
pathSafety suites unfiltered.

* 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.

The shadow reload promotes on frame-driven readiness (the player's
paint-and-idle, then two requestAnimationFrames) but failed on a
wall-clock 15s setTimeout. A hidden tab renders no frames, so every
external edit made while Studio was in the background failed with
"it took too long to load", the toasts stacked, and the stale preview
stayed up even after returning to the tab.
The budget now only runs while the document is visible: hiding the tab
clears the timer, and showing it again restarts the full budget for the
pending shadow, which then promotes normally.

* feat(registry): add text-match-cut — one text becomes another mid-move on a single 85 % curve
Video primitive reversed from an After Effects tutorial (Editing Snapped, "The Match
Cut Technique Every After Effects User Needs"), measured per frame at 60 fps. Both
texts ride one keyframe pair, cubic-bezier(.85, 0, .15, 1) over 2 s, and hard-swap at
the speed peak (1.0 s). A `mode` variable picks the property that carries the cut:
scale down (the tutorial), scale up, tracking in, or a same-direction slide in four
directions. Optional cyan-to-blue gradient sweep on its own 87 % curve, navy or
transparent background.

* feat(registry): add extended-keyframe, the never-fully-lands arrival with motion blur
A hyperframes:component. An element covers most of its move in the first fifth of the
duration and creeps the rest to the last frame (After Effects' extended-last-keyframe
technique), exits along the vector it arrived on, and carries shutter motion blur:
slides via the bundled feOffset filter smear, scale beats via a velocity-driven blur.
var a = attachExtendedArrival("#word", tl, { at: 0.3, from: { x: -1400 } });
attachExtendedArrival("#next", tl, { at: a.end, from: { scale: 0.35 } });
Direction and property agnostic (x / y / scale). The ease is exposed on its own as
EK.ease() for any tween, with EK.next() for sequencing and EK.gate() as a numeric check
(single velocity peak, no rises after it, tail above zero to the last frame).
registry/registry.json, docs/docs.json and docs/public/catalog-index.json regenerated
with the two generator scripts; they also pick up drift already present on main.

check-registry-set-delta.mjs only recognized removals: an added name in
registry.json had no matching allowance, so any pure-addition PR failed
with "unexpected in registry.json: <name>" even though the item's own
registry-item.json was added in the same diff. Mirror the deletion rule
for additions: a name is expected when its own registry-item.json was
added or deleted in the same diff, same condition either side already
required.
CI's audit tool flagged the CLI entry itself (high-crap-score rule,
scripts/check-registry-set-delta.mjs:30 main, CRAP 42.0 threshold 30.0,
cyclomatic 6): main() shelled to git and parsed JSON inline. The git/fs
boundary is now injected as runRegistrySetDeltaCheck(base, { run,
readRegistryJson }), covered directly by a test with a fake run/read, so
main() is a thin print-and-exit wrapper.

Implements the fixes from the 2026-09-21 cutover dashboard read
(plans/sdk/2026-09-21-cutover-dashboard-fixes-plan.md):
- sdk_cutover_failed now carries `family` and `error_kind`
(network/conflict/http/sdk). The one production gate event was a raw
`TypeError: Failed to fetch` from an unwrapped fetch (readProjectFile /
writeProjectFile's preflight), which an instanceof-only classifier would
still file as "sdk" and trip the rollback gate — added a message-based
fallback for the browser's fetch-rejection strings.
- studio:sdk_session_unavailable's `network` reason now carries `elapsed_ms`
and `hidden` (document.visibilityState at rejection), separating a
near-instant policy block (CSP/PNA/extension) from a dropped connection
the tab or server going away mid-flight.
- The ownership-race branch in useSdkSession's open effect now emits
sdk_session_superseded instead of sdk_session_unavailable{stage:ownership}
— it's a benign race (identity moved on mid-open), not a broken
precondition, and was being counted as one on the dashboard.
- Root-caused and fixed the read-404 "storm": /api/events (CLI host) and
the vite-dev hot-reload channel are one connection per SERVER, not per
project. A stale tab left open after `hyperframes preview` restarts on a
different folder (same port) received every save the CURRENT project
made, reloading its preview (which then 404s) and re-reading its own
composition on each one. Both transports now carry `projectId`; the
client-side coordinator drops a delivery whose projectId doesn't match
the tab's (absent field still passes, for one release of skew).
- studio-server's file routes report `why` on 403/404: `project_dir_missing`
(new — the CLI host's static resolveProject kept answering for a project
whose folder was renamed/deleted under a running server, which used to
fail closed as an indistinguishable path-traversal 403) vs `nul` vs
`outside_project`.
- absent_or_empty reads now carry `path_in_tree` (against the caller's
loaded file tree). Instrumentation only, per the graveyard page
(clearing-activecomppath-on-tree-absence) that refuted the "clear
activeCompPath" fix this was the proposed next step for.
Tests: unit coverage added for every change (sdkCutover.test.ts,
useSdkSession.lifecycle.test.tsx, useExternalFileChangeCoordinator.test.tsx,
studioServer.test.ts, files.pathSafety.test.ts). oxlint/oxfmt clean,
tsc --noEmit clean on studio/studio-server/cli.

* feat(registry): add colorama-wipe, a colour-mapped feathered wipe reveal for headlines
A hyperframes:component recreating the After Effects "shiny wipe": masked text +
Compound Blur + Colorama over a moving gradient, with a crisp duplicate fading on top.
One call per text element:
attachColoramaWipe("#headline", tl, { at, in, hold, out, cycle, feather, tilt, blur })
adds a single linear clock tween to the host timeline and paints the effect on two
canvases over the element's box; the element is hidden (visibility) with its layout
kept. All sizes scale from the element's font size. Deterministic: hash noise keyed by
frame, no Math.random, no clocks; seeks outside the window paint an empty stage.
registry/registry.json, docs/docs.json and docs/public/catalog-index.json were
regenerated with the two generator scripts as the contributing guide asks; they also
pick up drift already present on main.

* feat(studio): timeline clips take the designed material
Picture clips use an 8px radius and audio clips a 21px pill.
Clips sit one step above the lane. The label is a chip that

1px inner highlight. Hover background is the only transition.

Menus and popovers open and close with no fade. Hover colour is unchanged.

Menus, popovers, and dropdowns start at opacity 0.8 and scale 0.97, then settle in 120ms. They close in 90ms. Tooltips use the same shape in 100ms.

#4153 added supported speed ramps as rate lanes in data-automation. The
previously unselected capability tests still required preprocessing.
Require the documented rate-lane representation and its precedence over
the constant playback rate, matching the runtime resolver.

Wrap the lines oxfmt rejects so the format check passes.
* fix(registry): regenerate the week-in-merges catalog payload
The format pass left the committed payload off the generator output.
* feat(registry): cap week-in-merges at twelve rows
The block races at most rows_max authors, highest merge count first, and writes one line for everyone left out. The default is 12, so a long list cannot shrink the rows.
* fix(registry): make week-in-merges speed follow merge count
A row now travels the leader's pace times its merges over the leader's count. Only a zero stays on the floor, so a near-tie no longer looks like last place.
* feat(studio): audio meter faders for groups and master
* fix(studio): meter's mid band uses amber-500, the theme's actual token
yellow-500 was reset to nothing by palette-reset.css (--color-*: initial)
and never redefined in theme.css, so the mask never revealed any color
for -6 to -3dB; the token gate test already catches this and was red.
* refactor(studio): rename YELLOW_AT to AMBER_AT to match the amber token
* fix(studio): fader nudge and aria-valuenow match the visual dB position
* refactor(studio): use core StereoLevel for meter channel shape
* fix(core): emit levelTap in the packed core build
* fix(studio): name the preview fader Monitor and share clampNumber
* fix(studio): split the meter rAF tick and cover its branches
* style(studio): oxfmt AudioMeterStrip tests
* fix(studio): preserve authored gain in audio meter faders
* fix(studio): make timeline audio meters opt-in
* feat(studio): typed audio values, clip fades, audible video drops
Audio rows in the media inspector (Volume, Speed, Media start) take a
typed value: click the readout, type "-6 dB", "1.5x" or "2.5s", Enter.
Speed presets are hidden on <audio> clips.
Clip-edge fades: data-fade-in / data-fade-out in seconds, honoured by the
preview runtime (per-tick gain), the render mixer (afade after volume) and
Studio (Fade in / Fade out rows, and drag dots at the top corners of audio
clips and audible videos). Linear on both sides so preview and render
agree; fades that outrun the clip scale to meet inside it.
Dropped videos with an audio stream now land with data-has-audio="true"
instead of muted, so the mixer keeps their sound. The media metadata
endpoint reports hasAudio from the ffprobe call it already makes.

* fix(audio): one owner for fades, dB, and afade-after-volume
Illegal fade values become no-fade at fadeGain; typed inspector input
still returns null so the readout stays red. Master and group mixes
share one filter chain with volume then afade. Fade-out stays anchored
to the trimmed clip end.
* fix(studio): share audio helpers and bound typed media values
* fix(studio): reserve sibling fade duration when editing
