The committed artifact was generated with an older esbuild than the
current lockfile resolves; CI's check:position-edits-render regen now
produces different (equivalent) minifier variable naming and fails the
diff gate. Regenerate to match — no source change to positionEdits.ts.

A window.__timelines entry is authored content and may be a partial
RuntimeTimelineLike (duration/seek only, no pause). Timeline resolution
is deliberately permissive — duration-based — and such compositions
render fine, because the render path only seeks. But every interactive
transport path (play/pause/seek, bind, rebind-tick, boot) called
capturedTimeline.pause() unguarded, crashing studio playback with
'tl.pause is not a function' — the top recurring studio:unhandled_error
in telemetry across versions 0.6.121 through 0.7.59 (~150-175/day).
Guard all pause sites through one helper (typeof check + swallow, plus
a once-per-page timeline_missing_pause analytics event so composition
authors can find the partial timeline), matching the safeVoid pattern
player.ts already uses. In the rebind restore path, pause is guarded
separately so a missing pause() no longer aborts the seek/play restore
behind it in the same try/catch.

Both panels showed Layout (X/Y/W/H/Rotation/Z-index) unconditionally —
no gate existed for it at all — and Style was gated only on
canEditStyles (a permission check), never on the element's tag. Neither
gate accounted for `<audio>`, which never paints a visual frame, so a
music track's inspector showed a full set of position/size/fill/shadow
controls with zero visual effect.
Add `layout`/`style` applicability to resolveEditingSections (core),
keyed on tag !== "audio", and gate both panels' Layout section and the
existing Style gate on it. Media/Motion/Grade/Text were already
correctly gated (verified via a research pass across both panels) and
are untouched.
6px between rows left little clearance above a row's value for the
promote-to-variable badge (now positioned above the row). Widen the
row gap to 10px.
Shrinking the wrapped control's width to make room for the badge (previous
commit) fixed the overlap but pushed the value left unnecessarily. Move the
badge to sit above the row instead, clearing the value without touching its
layout.
PromotableControl absolutely-positions its "◇ var" / "◆ {id}" badge over
the wrapped control without reserving any space, so on rows where the
value renders flush to the right edge (flat Font/Color rows) the badge
sat directly on top of the value text instead of beside it. Add a
right-padding gutter on the wrapper sized to each badge state, and cap
the bound chip to a fixed max-width so it always fits inside its gutter.
Addresses R2 CHANGES_REQUESTED from Miga + Rames on PR #2529:
1. Sibling-surface gap (blocker): `hyperframes cloudrun render{,-batch}`,
`hyperframes lambda render{,-batch}` all advertised the same tier-only
aliases (`1080p` / `hd` / `4k` / `uhd`) but normalized them to `landscape`
and never set `outputResolutionAspectAgnostic`. The distributed plumbing
PR #2529 added received `undefined` from those callers, so portrait `1080p`
still hit the original aspect-mismatch on Cloud Run / Lambda.
Fix: introduce `resolveResolutionFlagPair` in `@hyperframes/parsers` (the
single source of truth for the two-step normalize + aspect-agnostic
detect) and route every distributed entrypoint through a shared
`parseOutputResolutionFlag` CLI util so the alias signal now reaches
`SerializableDistributedRenderConfig`. Studio Server keeps its
canonical-only HTTP contract; that intent is now pinned in tests.
2. Preflight recompute (hardening): the earlier "downgrade aspect-mismatch"
preflight cleared un-remapped mismatches, so IG 4:5 (non-preset aspect,
no sibling) and portrait-4K comp + `--resolution 1080p` (remap +
downsample) both slipped through to fail late in `resolveDeviceScaleFactor`.
Now `checkRenderResolutionPreflight` computes the effective preset via
`suggestMatchingPreset` (mirroring the compile stage's
`adaptAspectAgnosticResolution`) and re-checks against that — only
genuinely-fixable mismatches clear early. New tests pin both regressed
input classes.
3. Docker forwarding boundary test (Miga's important #2): pinned
`1080p` survives verbatim as `--resolution 1080p` in the Docker args
so the in-container CLI can re-run `isAspectAgnosticResolutionAlias`.
4. Doc-nit (Miga): parsers/src/types.ts no longer references the
nonexistent `resolveResolutionForComposition` — points at the actual
remap helpers.
Fallow: cloudrun.ts / lambda.ts share 390 lines of pre-existing structural
symmetry (parallel AWS + GCP dispatchers), and lambda/render.ts +
render-batch.ts declare parallel RenderArgs interfaces. Both re-flagged
after threading the aspect-agnostic field through each surface; ignored
with justification in .fallowrc.jsonc. lambda.ts's `run` and
lambda/render.ts's `waitForCompletion` are pre-existing CRAP-score
hotspots untouched by this PR — added under health.ignore.

Stroke width committed border-width and border-style together from one
free-text field, so setting a style meant typing an exact CSS keyword
(e.g. "dashed") with no indication of which ones were valid — the row
also duplicated the discoverable Stroke style select directly below it.
Stroke width now only commits border-width; style changes go exclusively
through the existing select.
FlatRow lays out label…gap…value across a `justify-between` row, but the
shared CommitField input it wraps had no text-align, so its text hugged
the LEFT edge of the value's own (often much wider) right-hand box —
looking left-aligned relative to the row, out of step with FlatSelectRow
and FlatSlider, which already right-align.
Added an optional `align` prop to CommitField (default "left", preserving
the legacy panel's MetricField/DetailField layouts where label-then-value
sits inline and left reads naturally) and pass `align="right"` from
FlatRow. Left the Motion Timing row's Start/End/Duration cells alone —
those stack label-above-value in a grid, a different pattern from the
inline label…value row this fix targets.
New tests: FlatRow's input has `text-right` (not `text-left`); the legacy
MetricField's input keeps `text-left` (not `text-right`), pinning
CommitField's default so the shared component doesn't drift for the
panel that didn't ask for this.
Full studio suite (2645 tests) green; typecheck/oxlint/oxfmt clean.
Reported as "template variables are broken": binding an element's field to a
variable via the flat inspector's "◇ var" promote chip (or editing an
already-bound field's value) wrote the correct bytes to disk, but the
Variables tab kept showing the pre-edit value until the whole Studio page
was hard-reloaded.
Root cause: DesignPanelPromoteProvider deliberately opens its OWN SDK
session (`useSdkSession(projectId, selection.sourceFile ?? activeCompPath)`)
so that promoting inside a sub-composition binds the variable in the
sub-comp's own file, not the host's. For the common case — a top-level
element, same file as `activeCompPath` — this session is a SEPARATE
in-memory `Composition` instance from the shared one `VariablesPanel`
(Variables tab, Slideshow, etc.) reads. A persist through the promote
provider's session never fires the shared session's own "change" event.
Worse, the shared session's file-change listener runs
`isSelfWriteEcho(path, content)` to decide whether to reload — but
`sdkSelfWriteRegistry` is keyed by file path only, not by session instance
(its own doc comment assumes "the studio process has a single SDK session
lifecycle at a time"). It sees the promote provider's write registered
under the same path and concludes it's its own echo, permanently
suppressing the reload it actually needs.
Threaded `forceReloadSdkSession` (the same mechanism every other
server-side-write path in Studio already uses for exactly this "resync
after a write I didn't make myself" case) from App.tsx through
StudioRightPanel into DesignPanelPromoteProvider, and call it after every
successful promote/setDefault persist — unconditionally, not gated on the
promote target matching activeCompPath, since re-opening a file that
didn't change is a harmless no-op re-parse and a path-equality guard here
already produced one subtly wrong comparison (activeCompPath can be null
while the shared session still defaults to "index.html") before landing on
this simpler version. Verified live: editing a variable-bound field's
value now updates the Variables tab immediately, no reload required.
App.tsx crossed the 600-line file-size gate after threading the new prop;
extracted the tiny handleAddAssetAtPlayhead wrapper into its own
useAddAssetAtPlayhead hook (with a regression test) to bring it back under.
Full studio suite (2639 tests) green against a fresh main; typecheck/
oxlint/oxfmt clean.
Fallow flagged the `uncaughtException` arrow at CRAP 30.0 (right at
threshold). Extracting the three exit paths — emitCliErrorEvent,
reportPostRenderTerminationEvent, exitAfterPostRenderTermination,
exitAfterCliFailure — pulls the two `_flushSync?.()` optional-chain
branches out of the arrow body and drops cyclomatic to 3. Same shape
already used on compileStage in a sibling PR. Behavior preserved:
EPIPE → exit(0), renderSucceeded → report + flush + exit(0),
default → commandFailed + track + flush + exit(1) for uncaught;
renderSucceeded → report + return, default → commandFailed + track
for rejection.
Windows contactSheet flake: `createContactSheet > writes PNG output`
timed out at 20025ms (default ceiling 20000ms) on Windows. Test does
milliseconds of real work — the wall-clock overhead is sharp's native
binary fork under runner I/O jitter. PR #2492 already tried lightening
the test; the flake persists at the default ceiling. Bumping the
per-test timeout to 60s absorbs runner jitter without hiding real
slowdowns (a genuine sharp regression would blow through 60s just as
readily as 20s). Targeted per-test bump, not a global suite bump.

The prior fix (dc410ca) dropped `pathToFileURL` from the pad-concat step
to make FFmpeg 8.x on Windows stop rejecting `file:///C:/…` URLs — but
kept feeding the concat script via `pipe:0` stdin. That combination
broke Linux CI: FFmpeg's concat demuxer resolves bare paths in the
script against the base URL of the script's own source, and when the
script is fed via `pipe:0` the base URL is `pipe:`. Absolute POSIX
paths (`/tmp/foo.aac`) then join to `pipe:/tmp/foo.aac`, which the
demuxer tries to open as a pipe and fails with:
[concat @ 0x…] Impossible to open 'pipe:/tmp/…/audio.aac'
pipe:0: End of file
Manually reproduced with `ffmpeg-static@7.0.2` on this repo's binary.
Fix: write the concat script to a real temp file (`<outputPath>.concat-
list.txt`) and pass `-i concatListPath` — matching the sibling concat
in `distributed/assemble.ts:180-186` exactly. A real file's directory
becomes the base URL, so absolute paths in the script resolve as-is on
both Linux and Windows. The `file://` scheme prefix stays out of the
script (Windows FFmpeg 8.x fix preserved) and no `pipe:` prefix gets
prepended (Linux regression fixed). Cleanup path list now covers both
the silence tail and the concat list script.
Also drops the now-unused `runFfmpegWithStdin` helper — no consumer
needs stdin plumbing anymore.
Regression pins in `audioPadTrim.test.ts`:
- `does not emit file:// URLs …` — Windows arg-shape pin (unchanged
intent, moved from `stdin` to `concatListContent` field).
- `materializes the pad-concat script to a real file …` — new pin
that asserts `-i` is not `pipe:0` and points at the concat list
path, so the Linux failure mode can't regress.
CI failures fixed:
- CI / Producer: integration tests (assemble.test.ts pad case)
- regression / regression-shards shard-1 (style-3-prod field-signal
end-to-end render exercising the assemble pad path)

pre-existing complexity; the PR only threads
`outputResolutionAspectAgnostic` through parseRenderOverrides /
RenderInput and does not touch `render`. Line-shift fingerprint —
exempted via health.ignore with justification comment.
- packages/producer/src/services/distributed/plan.ts `plan` (CRAP 36.7,
cyclo 33 — major): pre-existing complexity; the PR only adds one
optional field spread inside `plan` and does not add branches.
Line-shift fingerprint — exempted via health.ignore with justification.
- packages/producer/src/services/render/stages/compileStage.ts
`runCompileStage` (cyclo 23, cognitive 19 — minor): this one is a
real complexity bump from the two-branch aspect-agnostic re-target
block added in the fix. Extracted the block into a local helper
`adaptAspectAgnosticResolution` so `runCompileStage` stays under both
the cyclomatic (20) and cognitive (15) thresholds.
Verified locally with `fallow audit --base origin/main --fail-on-issues`
(exit 0, "No GitHub PR/MR findings") and `tsc --noEmit` on the producer

The aspect-agnostic resolution aliases (`--resolution 1080p` / `hd` / `4k` / `uhd`) previously all normalized to a landscape preset, which rejected portrait 1080x1920 compositions with 'Output resolution incompatible'. Users had to specify the orientation-bearing alias (`1080p-portrait`) or render at native.
This threads two new fields (`outputResolutionAspectAgnostic` + `outputResolutionRaw`) through the render pipeline. At the CLI layer we detect whether the user's flag was an aspect-agnostic alias; at the compile stage we re-map the preset to the composition's orientation via the existing `suggestMatchingPreset` sibling-lookup (formerly private). Explicit orientation-bearing aliases and canonical presets stay strict.

The render command's post-artifact-validated cleanup (telemetry flush,

valid, but the CLI exited 1 after the terminal "artifact validated" log

Introduce a `renderSucceeded` sentinel that flips after `executeRenderJob`
(or the Docker child render) resolves cleanly. From that point on:
- Post-render steps in the render command (trackRenderMetrics,
printRenderComplete, warnIfWebmAlphaDropped, maybePromptRenderFeedback)
run through `runPostRenderStep`/`runPostRenderStepAsync` guards that
swallow throws, log a compact warning to stderr, and sanitize a stray
`process.exitCode` back to 0.
- The CLI's top-level `uncaughtException` handler logs the throw for
diagnosis but exits 0 instead of 1 when the render already succeeded.
- The CLI's `unhandledRejection` handler stops flipping `commandFailed`
(which drove the success:false telemetry field) when the render
already succeeded.

Adds a `--timeout <ms>` CLI flag (and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS`

was the manual workaround.
- Add `--timeout <ms>` and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS` (min 5000).
Explicit override bypasses auto-scaling; still capped at 12h.
- Add per-model slowdown factor (tiny 0.5, base 0.7, small 1, medium 2,

- Wrap whisper's spawn error with a discoverability hint naming
`--timeout`, the env var, and the effective timeout when the child

- Explicit override honored below the auto floor + capped at 12h.
- Model factor ignored when overrideMs is set.

The `audioPadTrim` module's pad-concat step generates a concat script
whose file directives use `file://` URLs (built via Node's
`pathToFileURL`). FFmpeg 8.x on Windows rejects these with
"Impossible to open file:///C:/…" — its `file:` protocol handler strips
the scheme leaving `///C:/…`, which Windows path parsing then rejects.

Regression pin: unit test asserts the pad-concat stdin never contains
the `file://` scheme, including for a Windows-shaped input path.
End-to-end verification requires a Windows + FFmpeg 8.x reviewer; the
unit test snapshots the arg shape.

Review feedback on #2497 (Rames D Jusso) found a real gap: the exclusivity
this PR introduced only applied to the direct in-panel tab click, which
calls setExclusiveRightInspectorPane. Every OTHER caller that reaches
setRightPanelTab("design"|"layers") — element select (useDomSelection.ts),
closing block-params (App.tsx), the header Inspector button
(StudioHeader.tsx), and even this PR's own "!inspectorTabActive" entry
branch in handleInspectorPaneButtonClick — went through
trackedSetRightPanelTab's old unconditional additive
`{...panes, [tab]: true}`, reproducing the exact "both tabs highlight, only
one renders" bug this PR claims to fix. Confirmed via the reviewer's traced
repro: fresh boot, click Layers tab while no inspector tab is yet active →
rightInspectorPanes ends up {design:true, layers:true}.
Fixed at the reviewer's preferred choke point: trackedSetRightPanelTab
itself is now flat-aware, applying the same exclusive-radio update
setExclusiveRightInspectorPane does whenever STUDIO_FLAT_INSPECTOR_ENABLED
is on, falling back to the legacy additive update otherwise. This closes
the gap for every current and future caller of setRightPanelTab, not just
the one call site this PR touched.
New usePanelLayout.test.ts cases pin both directions: setRightPanelTab
stays additive under flat=off (legacy split-view behavior unchanged), and
enforces exclusivity under flat=on even when called directly (not through
the tab-click handler) — using the vi.doMock(manualEditingAvailability)
pattern already established in PropertyPanel.test.tsx for flag-dependent
module state.
Full studio suite (2643 tests) green; typecheck/oxlint/oxfmt clean.
The flat inspector split Layers and Design into a vertically-resizable
stacked pair whenever both panes were toggled on, mirroring the legacy
panel's layout. For the flat redesign this reads as two competing panels
crammed into one column; Layers should always render full-height by
itself there instead.
Gate the split-view branch behind !STUDIO_FLAT_INSPECTOR_ENABLED so it
still applies to the legacy panel, and fall through to Layers rendering
alone (the existing `layersPaneOpen` branch already does this — it just
never got reached previously because the split check ran first).
Also added setExclusiveRightInspectorPane (radio-style: selecting one pane
turns the other off) and use it for the Design/Layers tab clicks under the
flat flag, since leaving both panes independently toggleable would highlight
both tabs as "active" while only one actually renders.

Follow-up on Miga's review of #2512. The regression fixture
`escape-hatch-fatal-fallback` is tagged `field-signal-reproducer` and
`known-broken` so it's skipped from the default sweep via
`--exclude-tags transparency,field-signal-reproducer` in the
`test:regression*` scripts in packages/producer/package.json. But
`Dockerfile.test`'s ENTRYPOINT invoked the harness directly (`bunx tsx
src/regression-harness.ts -- --sequential`), bypassing those scripts —
so `bun run docker:test*` and the aws-lambda smoke tests would still
try to run the known-broken fixture and fail. CI's own regression sweep
was insulated only because it hardcodes per-shard positional test names
that don't include this fixture, but that's incidental, not by design.
Bake the exclude-tags into the Dockerfile.test ENTRYPOINT itself so
every user of the image (local `docker:test*`, aws-lambda smoke, any
adopter running the reference image) picks up the same skip contract.
Docker CMD args appended after the entrypoint (e.g. matrix shard
positional test names in .github/workflows/regression.yml, or
`--mode=distributed-simulated`) still parse correctly — the harness
applies excludeTags after testNames-filtering (see discoverTestSuites
in regression-harness.ts).
Also exports `parseArgs()` from regression-harness.ts and adds
regression-harness-parse.test.ts to pin the `--exclude-tags` comma-parse
contract, so any future change to the parser or the values baked into
the Dockerfile / package.json will trip a red test rather than silently
diverging.
Verification A (harness comma-parses `--exclude-tags transparency,
field-signal-reproducer`) already worked pre-fix; the new test file
codifies it. Verification B (Docker ENTRYPOINT propagates the same
skip) is what this commit fixes.

Field signal ts=1784040753 (#hyperframes-cli-feedback): a composition
with ~40 heavy overlay DOM elements — `filter:blur`, oversized
`radial-gradient`, and `clip-path` animations — captures solid-black for
the first ~half of the render, recovering near the end. Reproduces
identically via drawElement AND forced --no-browser-gpu screenshot
capture AND `snapshot`, so the capture layer itself is the offender, not
encoder/mux. Independent of duration (padding the timeline grows the bad
zone proportionally, doesn't shift it). Presence alone matters — even
opacity:0 / visibility:hidden / unused overlays contribute. Reporter's
workaround was splitting into per-transition mini-compositions +
FFmpeg concat.
Add compositionCheck rule `composition_heavy_overlay_count_high`
(warning). Counts DOM elements that carry any of: inline
`style` filter:blur / clip-path (non-none) / radial-gradient, or a
class/id whose top-level CSS rule body sets one of those. `display:none`
elements are counted-out (removed from render tree); opacity:0 /
visibility:hidden overlays are counted-in per the field-signal repro
shape. Warns at 25 to give lead time before the observed 40-element bad
zone. Skips registry source and installed-block files, mirroring
`composition_file_too_large`. Includes a `ts=1784040753` reference in
fixHint so authors can trace the risk shape.

Field signal ts=1784146416 (darwin/arm64, CLI 0.7.58, 7/10): host
page.goto hit Navigation timeout of 60000ms twice on a CSS 3D + audio
composition; Docker rendered the same composition successfully.
Puppeteer's stock "Navigation timeout of 60000 ms exceeded" text names
none of HyperFrames' existing escape hatches, so the reporter had no
signal that the failure had knobs.
Wraps main-render Puppeteer `page.goto` errors matching
/Navigation timeout|net::ERR_TIMED_OUT/i with an augmented message that
names:
- The effective timeout currently applied (`cfg.pageNavigationTimeout`).
- Raise-the-timeout: `PRODUCER_PAGE_NAVIGATION_TIMEOUT_MS` env,
`--browser-timeout` CLI flag (seconds).
- Browser-binary escape hatch: `HYPERFRAMES_BROWSER_PATH` env.
- Field-signal shape: darwin/arm64 + CSS 3D + audio compound Docker
hint — gated on all three inputs being explicitly true; falls back
to generic hints when any input is unknown.
Mirrors #2443's HYPERFRAMES_BROWSER_PATH surfacing pattern (which
covered download-time failures) at the runtime `page.goto` layer.
Non-matching errors flow through unchanged. Original error preserved
via `err.cause`.
Wired into `renderOrchestrator.executeRenderJob`'s top-level catch,
composed after `augmentProtocolTimeoutError` so the two augmenters
never both fire on the same error (mutually exclusive regexes).
Current wire-up passes no `hasCss3D` / `hasAudio` context — no
compile-time CSS-3D signal is threaded through the render pipeline,
and `hasAudio` is block-scoped inside the try. Per the helper's
fallback docs, unknown flags route to the generic env + browser-path
hints. A future compile-time CSS-3D scan can thread both flags to
enable the full compound Docker hint without touching this helper's
signature.

Field signal ts=1784131903 (win32/x64, CLI 0.7.58, 156s UI-heavy):
stable ONLY with four flags together — --workers 1 --no-browser-gpu
--low-memory-mode + PRODUCER_ENABLE_STREAMING_ENCODE=false. Since
--no-browser-gpu and --low-memory-mode already imply screenshot
capture, three of the four flags are structurally coupled. Auto-detect
the compound at resolveConfig time and disable streaming-encode on
the caller's behalf; user explicit-set (PRODUCER_ENABLE_STREAMING_ENCODE
or overrides.enableStreamingEncode) always wins.
Composition duration is not known at the config layer, so the wire-up
passes compositionDurationSec:undefined and the helper reduces to the
three-condition compound (platform + softwareGpuForced + workers=1).
The 4-arg helper stays exported for downstream callers that DO know
duration (e.g., renderOrchestrator) and want the >120s guard.
Trade-off documented in code + PR body: false positives possible for
short (~<120s) Windows software-GPU single-worker renders. Mitigation
is the explicit opt-in escape hatch.
Emits a single [hyperframes] log line naming the trigger + how to opt
back in, so operators can tell an auto-disable apart from an explicit
opt-out. Adds streamingEncodeAutoDisabledOnWin32Compound internal

Review feedback on #2473: HF_DE_PARALLEL_STALL_MS had no backwards-compat
shim after the rename to HF_DE_STALL_MS, and a parent abort during a wedged
sequential capture would surface as "stalled" instead of "aborted" in
downstream logs/telemetry (functionally harmless since isCancellation is
gated on abortSignal.aborted, not message text, but misleading to read).
`hyperframes render` picks up `PRODUCER_HEADLESS_SHELL_PATH` (engine
per-worker launches read it directly, and `render.ts` even propagates
the CLI-resolved executable path into it as a courtesy). But
`hyperframes check` / `snapshot` / `compare` / `grade-compare` all
route through `openSettledCompositionPage` → `ensureBrowser` →
`findFromEnv`, and `findFromEnv` only knew the CLI-native name
`HYPERFRAMES_BROWSER_PATH`.
Field report — #hyperframes-cli-feedback ts=1784095034 (win32/x64,
CLI 0.7.58): the cached `chrome-headless-shell 152.0.7928.2` crashed
with `Failed to launch the browser process: Code: 3221225595`
(`STATUS_STACK_BUFFER_OVERRUN`). Setting `PRODUCER_HEADLESS_SHELL_PATH`
to system Chrome unblocked `render`, but `check` still crashed on the
broken cached shell because it never read that env var.
Docs and deployment manifests (`skills/hyperframes-animation/adapters/
typegpu.md`, `packages/gcp-cloud-run/Dockerfile`, `examples/k8s-jobs/
Dockerfile.example`) all instruct users to set
`PRODUCER_HEADLESS_SHELL_PATH`, so the escape hatch is
documentation-blessed but was silently half-implemented on the CLI
side.
Alias it in `findFromEnv`. Tiebreak matches `render.ts:1479` —
`HYPERFRAMES_BROWSER_PATH` wins when both are set.
This is the CLI side of the symmetry #2459 is closing on the engine
(engine gaining `HYPERFRAMES_BROWSER_PATH` honoring); the two make the
alias coherent both directions.
- Sibling to #2443 (surfaces `HYPERFRAMES_BROWSER_PATH` on download
failures).
- Not the same class as #2040 (arm64 pin), #2078 (SIGTRAP), or #2082
(launch crash rewrap) — those are download / launch fixes; this is
the env-var alias gap.

Deepwork's request-changes on #2411 (twice): deFallbackReason's blank/psnr
split still ran /blank/i.test(err.message) even after this PR's stated goal
of moving off message-text parsing — a reworded message, a translated
string, or a differently-shaped error crossing a module boundary could
silently relabel a blank failure as psnr (or vice versa), corrupting the
soak's telemetry taxonomy.
DrawElementVerificationDetails now carries a required `kind: "blank" | "psnr"`
field, set at all three real throw sites in captureStreamingStage.ts. The
orchestrator derives deFallbackReason from getDrawElementVerificationDetails's
kind instead of regexing the message. Making `kind` a required constructor
argument means any future throw site that omits it fails to compile, closing
the gap for good rather than just at today's three call sites.
New tests in frameCapture.test.ts prove message-independence directly: kind
survives a reworded message that says neither "blank" nor "psnr", and stays
correctly "psnr" even when the message adversarially contains the substring
"blank" — the exact scenario a regex-based classifier would get wrong.
Review feedback on #2411 (Rames): the crash-survival RenderCaptureObservability
mirror passed deFallbackFailedDb raw/unrounded while the render_complete
perfSummary path rounded to 1 decimal — the same underlying PSNR could ship two
different values to PostHog depending on which event fired. Extracted the
existing inline round/clamp expression (previously duplicated for verifyMinDb
and fallbackFailedDb) into a shared roundDb helper, applied once at the single
point deFallbackFailedDb is derived from the thrown error so both downstream
consumers agree.
Also threads verifyThresholdDb (captured on the error but never propagated,
per the nit) through DrawElementPerfInput/RenderCaptureObservability/render.ts/
telemetry as de_fallback_threshold_db on both events — the HF_DE_VERIFY_MIN_DB
value the failing dB breached, letting ops read "28.4dB failed a 32dB
threshold" directly instead of cross-referencing config.
de_fallback_reason only told you the fallback happened (blank/psnr/oom/
capture_error), not the failing PSNR or frame index — that data existed as
text inside the thrown error's message and was discarded on the way to
telemetry. DrawElementVerificationError now carries structured
frameIndex/failedDb/verifyThresholdDb; the orchestrator reads them via the
new getDrawElementVerificationDetails helper instead of regexing message
text, and both telemetry surfaces (the render_complete perfSummary path and
the crash-survival RenderCaptureObservability mirror) emit
de_fallback_failed_db / de_fallback_frame_index.
Needed to distinguish "32dB vs the 32dB threshold, tune it" from "12dB real
corruption, investigate" during the parallel-router soak — currently that
distinction is invisible.
Miga review nit on #2443. Existing test only covered darwin/arm64 by
default; parameterize via it.each across process.platform so each platform's
Chrome-path hint from browserPathHintForPlatform is asserted in the rethrown
error message.

CI's file-size check (which diffs against origin/main, not per-commit like
the local lefthook gate) flagged useDomEditCommits.ts at 602 lines. Extracted
the standalone atomic-patch-batch helpers (formatUnsafeFieldList,
getErrorDetail, readErrorResponseBody, formatPatchRejectionMessage,
patchElementBatches, batchesAreInlineStyleOnly,
AtomicElementPatchConvergenceError) into useDomEditCommitsHelpers.ts — none
of them close over hook state, so this is a pure move. useDomEditCommits.ts
is now 451 lines.
Typecheck/oxlint/oxfmt clean; useDomEditCommits.test.tsx (28 tests) and the
full studio suite unaffected.
Fixes real bugs from two independent re-reviews (#2225 @ 65954c3804,
#2416 @ beaf4ffbf6):
- FlatTimingRow's pinRange committed a pinned start+duration range through
TWO sequential onSetAttribute calls. Each resolves domEditSelection fresh
from current hook state, so a selection change between the two awaits
could misdirect the second write at the newly-selected element instead of
the one being edited, and a failure of just the second call left the pair
half-applied (inconsistent inferred/explicit state). Added
commitDataAttributes/handleDomAttributesCommit (mirroring
onCommitAnimatedProperties's same-shaped fix for GSAP property batches):
one PatchOperation[] persist call against an explicit, caller-supplied
selection — not the "current" one — threaded through as the new optional
onSetAttributes prop. pinRange uses it when provided, falls back to the
old sequential behavior otherwise.
- Hide All silently dropped nested sub-composition children: a selection
inside a sub-comp with no timeline-store entry of its own resolves to a
virtual `sourceFile#domId` key (the fallback branch exists so the
expansion hook can later resolve it via clipParentMap), but
toggleTimelineElementHidden only searched the RAW store list, which never
contains that key. useTimelineElementVisibilityEditing now resolves
against useExpandedTimelineElements() instead, matching the track-based
toggle's existing approach — the expanded list synthesizes a real,
patchable TimelineElement (matching key/domId/sourceFile) for each visible
child whenever its host is currently expanded.
- Two composition hosts importing the same sub-composition collapsed to
the first one: findMatchingTimelineElementId ORed domId/selector/
compositionSrc matches with equal priority in a single per-element scan,
so `.find()` could stop at an EARLIER, unrelated host that merely shared
the compositionSrc, before the scan ever reached the correct domId/
selector match further down the list. Restructured to try domId, then
selector, across the WHOLE list first; compositionSrc-only matching is
now a true last resort for when neither identifies a specific element.
- FlatSlider's native pointercancel handler (a platform-level gesture abort
— scroll/touch takeover, pen leaving range) manually duplicated the
pointer-capture release logic instead of calling cancelDrag, so it never
reverted to the pre-drag value — leaving whatever intermediate position
the pointer last reached committed, unlike the Escape/right-click paths
added in the previous round. Now calls cancelDrag directly.
- useColorGradingController's flushPendingPersist read identityKeyRef.current
fresh at flush time rather than a value snapshotted when the edit was
scheduled. Defensive fix: added pendingPersistIdentityRef, set alongside
pendingPersistValueRef in commitColorGrading, read by flushPendingPersist
instead of the live ref — closes the gap regardless of how unlikely the
actual race is given the identity-cleanup effect's existing eager-flush
behavior.
Two prior findings re-verified as already fixed further up this same
Graphite stack (not re-fixed here, per established stack-order handling):
metadata-cache negative-caching (267cdfce1) and cross-file
selectionIdentityKey (6f40e03a1), both landing after #2225's reviewed head.
StudioRightPanel.tsx crossed the 600-line file-size gate after wiring the
new onSetAttributes prop through; extracted the inspector split-pane resize
handlers (previously inlined) into their own useInspectorSplitResize hook.
New regression tests: repeated-composition-host resolution, atomic vs.
fallback pinRange commit paths, pointercancel revert. Full studio suite
still at the known pre-existing 55-failure baseline, zero new regressions.
Typecheck/oxlint/oxfmt clean.
A fresh full-stack re-review checked 15 PR heads independently. Cross-
checked all 9 remaining claims against the actual current tip:
- #2120 (id/selector key qualification, Hide All no-op/race, variable
parity), #2121 (opacity-zero fallback), #2122 (GSAP preview sibling
resolution, scrub-label), #2124/#2126 (negative metadata cache), and
the keyboard-access half of #2121/#2186 were all already fixed by a
later commit in this same stack (65954c380, PR #2225) — the reviewed
heads predate it. Verified each in the current source rather than
taking the isolated-head review at face value.
- #2186's "no ESC/right-click cancel during drag" was the one claim that
held up: FlatSlider had keyboard arrow-key support but no way to abort
an in-progress pointer drag. Escape now reverts to the pre-drag value
and releases pointer capture; a right-click (contextmenu) during a drag
does the same instead of committing whatever position the pointer last
reached while the native context menu opens over the slider. Both go
through commitDraft (not just a visual reset) since the drag's leading-
edge commit in onPointerDown may already have applied an intermediate
value that needs actually undoing, not just hiding.
propertyPanelFlatPrimitives.tsx crossed the 600-line file-size gate after
this change; extracted FlatSelectRow into its own file, matching the
FlatToggle/FlatMaskInsetRows precedent from earlier in this stack.
New regression tests for Escape-cancel and contextmenu-cancel. Full
studio suite still at the known pre-existing 55-failure baseline, zero

Fixes the four blockers from the #2416 re-review at head d6a40c38b:
- FlatSlider's onPointerUp calls releasePointerCapture() explicitly, which
fires lostpointercapture SYNCHRONOUSLY in real browsers — the prior
unconditional onLostPointerCapture resync ran mid-onPointerUp, flipping
draggingRef false before onPointerUp's own check, silently dropping every
normal drag-release's final commitDraft(). happy-dom doesn't replicate the
synchronous cascade, so this shipped without a failing test. Added an
explicitReleaseRef flag set right before each deliberate
releasePointerCapture() call so onLostPointerCapture can tell "our own
release, caller's logic already handles it" apart from a genuine external
capture loss. Added a regression test that monkey-patches
releasePointerCapture to reproduce the real-browser ordering.
- persistColorGradingValue read onSetAttributeLiveRef.current (reassigned
every render) instead of the callback live when the debounced edit was
scheduled — a timer for element A firing after a re-render for element B
would wrongly call B's callback with A's data. Removed the ref; the
callback is now an explicit parameter captured by commitColorGrading's own
closure (added to its useCallback deps) and threaded through to
persistColorGradingValue and flushPendingPersist.
- flushPendingPersist passed () => true as its isLatestAttempt checker,
bypassing the per-commit version guard entirely. Now calls
bumpDomEditCommitVersion(gradingVersionRef) like a regular debounced
commit, so a newer edit landing before the flushed write settles still
wins the race.
- The selection-identity cleanup effect stopped clearing statusTimersRef
during an earlier refactor — stale RUNTIME_STATUS_REFRESH_DELAYS timers
for an outgoing element could fire after switching selection and stamp
the new element's runtimeStatus with the old element's answer. Restored
the clear in the same effect cleanup.
Also gave the Custom LUT and "Copy grade to" scope <select> controls
aria-labels — both had their visible text in a sibling span/text node, so
neither had an accessible name.
Full studio suite still at the known pre-existing 55-failure baseline
(variablePromoteIntegration, useGsapPropertyDebounce, sdkCutover(Parity),
sdkResolverShadow), zero new regressions. Typecheck, oxlint, oxfmt clean.
Fixes three of the adversarial findings from the third #2416 tip
re-review:
- Grade rollback was identity-scoped but not attempt-scoped: two edits on
the SAME element (e.g. drag Exposure, then Contrast, before Exposure's
persist settles) could have the earlier edit's late completion stamp
confirmedGradingRef with its now-superseded value, or revert `grading`
out from under the newer optimistic edit. Added a monotonic per-commit
version via the existing bumpDomEditCommitVersion primitive (the same
one the DOM-attribute commit runner uses for the identical race) —
persistColorGradingValue now checks both identity AND "is this still the
latest attempt for this element" before applying any effect.
- The render-phase identity-reset block consumed shared mutable state
(clearing the pending-persist timer, reading and nulling
pendingPersistValueRef) directly during render. Adjusting STATE during
render this way is React's documented pattern and safe to repeat, but
consuming a ref this way is not: if React discarded/interrupted that
specific render before it committed, the timer would already be
cancelled and the pending value already nulled, with no corresponding
effect ever running to compensate, silently losing the edit. Replaced
with the idiomatic pattern for "clean up a per-identity resource when it
changes" — a useEffect keyed on identityKey whose CLEANUP performs the
cancellation/flush. A cleanup only ever runs for the effect instance
that actually committed, closing the gap entirely. The render-phase
block now only performs pure, idempotent state resets.
- FlatSelectRow's Preset row passes label="" (the visible "Preset" text is
a sibling span, to avoid rendering it twice) which left the underlying
<select> with no accessible name at all. Added a dedicated `ariaLabel`
prop, distinct from the visible `label`, so a caller can supply a name
without a duplicate visible label.
Also hardened FlatSlider's lostpointercapture handling: it now resyncs
the draft directly from a latestValueRef immediately, instead of only
clearing the dragging flag and waiting for the separate [value]-keyed
effect to notice — closing a narrow ordering gap where a value change
arriving while still dragging, followed by capture loss with no further
render, could otherwise leave the knob stuck.
propertyPanelFlatPrimitives.tsx crossed the 600-line file-size gate after
these changes; extracted FlatToggle (and its tests) into their own files,
matching the FlatMaskInsetRows precedent from an earlier commit in this
stack.
New/updated regression tests: same-element version race, Preset select's
aria-label. Full studio suite still at the known pre-existing 55-failure
baseline, zero regressions.
Fixes two of the three adversarial findings from the second #2416 tip
re-review; the third is a pre-existing runtime-protocol gap, explained in
the PR thread rather than patched here.
- The Grade rollback added in the previous commit could never fire through
the real Studio callback: runDomEditCommit (the shared commit runner used
by every data-attribute commit, not just Grade) catches persist failures
internally and always resolves, reporting outcome only via its own
onError side effect. A caller awaiting the promise never sees a
rejection, so the revert-on-reject logic was dead code against the
actual app. Added an optional onSettled(ok) callback to
DomEditCommitRunnerConfig (purely additive — every existing caller that
doesn't pass it is unaffected) and threaded it through
commitDataAttribute -> handleDomAttributeLiveCommit -> the
onSetAttributeLive prop type (now accepts an optional 3rd argument) ->
useColorGradingController, which now drives the revert from the real
signal. The promise-rejection path stays as a fallback for any other
implementation of onSetAttributeLive that rejects instead.
- Selection flushing performed a real side effect (writing the outgoing
element's pending edit) during the render-phase identity-reset block.
Adjusting STATE during render (comparing against a ref) is React's
documented pattern, but it doesn't license actual I/O — React can invoke
render more than once per commit, which could double-fire or misorder
the write. The reset block now only enqueues the flush (a pure ref
write); a new effect keyed on the identity performs it after commit.
- Async persist completions (both the onSettled callback and its promise-
rejection fallback) now capture the identity key the attempt was made
for and check it against the CURRENT identity before touching
confirmedGradingRef/grading/runtimeStatus. Without this, a persist that
settles after selection has moved on to a THIRD element could clobber
that element's freshly-reset state with a result that belongs to an
element no longer selected.
Not fixed here: the runtime Grade target (HfColorGradingTarget, used by
core's resolveTarget to find the DOM element inside the preview iframe)
has no source-file/composition-scope discriminator, matching the same gap
selectionIdentityKey had before this stack — but fixing it means changing
a wire-protocol type shared across core/player/studio and the legacy
ColorGradingSection too. hfId (checked first, before id/selector) is
minted uniquely per element at parse time in the common case, so this is
a narrow residual risk for hfId-less same-selector elements across
different source files, not a regression introduced by this stack.
Flagged as a follow-up in the PR thread.
New/updated regression tests: real onSettled(false) path (distinct from
the promise-rejection fallback), and a stale in-flight persist settling
after selection has moved on twice more. Full studio suite still at the
known pre-existing 55-failure baseline, zero regressions.
Fixes the Deepwork tip re-review's four remaining blockers plus its
additive findings:
- selectionIdentityKey: add sourceFile as a 5th identity component. The
same local id/selector can legitimately recur across different
composition files (host vs. an inlined sub-composition, or two unrelated
sub-comps) — without sourceFile, those collided onto the same identity
key and reused stale controller state across a selection change that
should have reset it.
- useColorGradingController: flush (not discard) a pending Grade edit when
selection changes before the 350ms debounce fires. The prior fix
correctly stopped it from landing on the WRONG (new) target, but
cancelling outright silently dropped the user's in-flight edit instead of
writing it to the element it was authored for — using the
onSetAttributeLive closure captured for the outgoing render, which
(via commitDataAttribute's own useCallback deps) is still bound to the
outgoing selection.
- useColorGradingController: revert to the last confirmed-good grading when
a persist rejects, instead of leaving the optimistic (never-actually-
saved) value showing indefinitely. Tracks a separate
confirmedGradingRef, updated only on a successful persist.
- FlatSelectRow: disable the reset button when the row itself is disabled
(it previously ignored disabled entirely, same class of bug as the
FlatSlider reset button fixed earlier) and give the underlying <select>
an aria-label from the row's label text.
- FlatSlider: handle lostpointercapture the same as pointercancel — capture
can be lost without either firing first (another element steals it, or
the browser reclaims it for a scroll/touch gesture), which previously
left the dragging flag stuck and the knob permanently unable to sync to
external value changes.
New regression tests for all of the above; full studio suite still at the
known pre-existing baseline (55 failures unrelated to this stack).
Fixes issues raised in the Deepwork re-review of #2120-#2190 that weren't
covered by #2225's earlier fix pass:
- useColorGradingController: reset grading/compare/mediaMetadata state (and
cancel pending persist/status timers) when selection changes to a
different element — this hook is called unconditionally on every render
(unlike legacy ColorGradingSection, remounted via a selectionIdentityKey
React key), so switching selection reused the previous element's state.
- useColorGradingController: stop permanently caching a non-OK
/media/metadata response as null — a transient server error poisoned the
HDR banner for that asset for the whole page lifetime.
- FlatSelectRow: preserve a valid authored value outside the preset list
(e.g. mix-blend-mode: difference, an arbitrary object-position) instead of
silently misrepresenting it as the first preset — touching the control
would overwrite real persisted state.
- FlatSlider: the throttled trailing commit now reads onCommit through a
ref updated every render instead of closing over it at schedule time — a
caller whose onCommit spreads other current state (Grade's per-detail
commits) could otherwise have a delayed commit revert whatever the user
changed on a different control in the same 40ms window.
- FlatSlider: flush a still-queued trailing commit on unmount instead of
dropping it, and disable the reset button when the slider itself is
disabled.
- FlatSlider: add touch-action: none to the track so touch drags don't
compete with page scroll.
- FlatColorGradingAccessory: clean up the compare-hold's window listeners
on unmount, not only on release — switching selection mid-hold used to
leak them.
- Align (flat Text): re-clicking the option already visually active for a
logical start/end value no longer rewrites it to the physical left/right,
preserving RTL semantics.
- FlatSegmentedRow: give every option an accessible name and aria-pressed
state — two visually-identical glyph buttons (upright/italic "A") had no
way to be told apart by assistive tech.
- PropertyPanelFlat: the panel body falls back to its own scroll when the
collapsed group headers alone exceed the available height, so groups
can't become permanently unreachable in a short pane.
New regression tests for all of the above; full studio suite at the known
pre-existing baseline (55 failures unrelated to this stack).
A pure debounce resets its timer on every pointermove, so a real drag
(events faster than 40ms apart) never commits until the pointer pauses
or lifts — killing live preview updates mid-drag. Throttle with a
leading-edge commit + trailing flush instead.
Only onPointerDown was wired, so dragging the knob/track only ever
committed the initial click position — nothing tracked the pointer
after that. Uses the Pointer Capture API (setPointerCapture on
pointerdown, onPointerMove while captured, release on pointerup) so
the value follows the cursor continuously during a drag, matching how
the legacy native <input type="range"> control behaves for free.

The track's visible line was only 2px tall, and pointerdown was bound
directly to that thin element, making it hard to grab. The hit area is
now 20px tall (a wrapping div) with the visible line rendered as a
thin decorative child, centered inside it — the ratio math only reads
left/width so click accuracy is unaffected.
