Inside Codex's seatbelt the GPU probe's Metal Chrome is always killed, and
when it dies after puppeteer's setAutoAttach is answered, puppeteer waits
forever for its initial targets. The probe now answers software in a named
seatbelt without starting Chrome, and every CLI browser launch is bounded
by its timeout, so a stuck launch rejects and a signal can end the command.

writeSfxCredit cleans the credit and source link itself, since the CLI writes
credits from a saved record. Backticks, brackets, angle brackets and backslashes
are stripped, and a source link must be https on an Openverse audio provider host
(Freesound, Jamendo, Wikimedia Commons) or it is left out.
lambda reported any ERR_MODULE_NOT_FOUND as '@hyperframes/aws-lambda is not installed', and cloudrun matched its package name anywhere in the message, which also names the adapter when one of its own dependencies is missing. Both now use one helper that matches only Node's "Cannot find package '<pkg>'" and rethrow anything else.
lambda and cloudrun render at 30 fps when data-fps is outside the cloud set (for example 50 or 30000/1001) and --fps is not passed. They now say so and point at --fps. The 30 fps default has one owner, defaultCloudFps.
The integer rates Lambda and Cloud Run accept were written out by hand in
about 25 places across core, engine, producer, the adapters and the CLI.
They now come from DISTRIBUTED_FPS / DistributedFps / isDistributedFps in
@hyperframes/core. Engine config snapshots accept 25 like the rest.
* fix(cli): check's dense overlap pass takes at most 240 samples, at clip windows first
* fix(cli): a held overlap on a long film is still an error under the 240-sample bound
Lambda and Cloud Run renders refused 25 fps although it is an integer
rate like 24, 30 and 60, and PAL footage is 25 fps. The distributed fps
set is now {24, 25, 30, 60} in the producer's config validation, the
plan v2 manifest, the render request mapping, the Lambda and Cloud Run
event types, the CLI's lambda and cloudrun commands and the regression
harnesses.

## What a user can do now
Render a video at 720p or 480p: `hyperframes render --resolution 720p` (or `480p`, or the presets `landscape-720p`, `portrait-480p`, `square-720p` and so on) gives a 1280×720 or 854×480 file from a 1080p composition, and the same presets work through the studio-server render route. Before, any preset smaller than the composition was refused ("Downsampling via --resolution is not supported").
## How
- `parsers/src/types.ts`: six presets, `{landscape,portrait,square}-{720p,480p}`, and the `720p` / `480p` aliases (aspect-agnostic, like `1080p` and `4k`). 480p at 16:9 is 854×480: 480 × 16/9 is 853.33, and 4:2:0 encoders need even sides.
- `checkOutputResolutionCompatibility` now allows a preset smaller than the composition. A smaller preset may be off by under one pixel on its long side (the 854); a larger one must still match exactly and be a whole multiple, as before. The aspect remap that `--resolution 1080p` / `4k` apply on their own (`suggestMatchingPreset`, used by the CLI preflight and the compile stage) returns only a preset in the asked tier, never another: with the looser match for smaller presets, a 1922×1080 composition asked for `4k` would otherwise have been remapped to 480p. It is refused instead, as before.
- `resolveDeviceScaleFactor` returns the long side's ratio, so a smaller preset renders at a device scale factor under 1: Chrome lays the page out at composition size and rasterizes each frame straight at 1280×720 or 854×480, the way 4K already renders at 2. For 480p that is 854/1920: the width lands on 854 exactly and the height's 480.375 rounds to 480, so no pad column is added. Output sizes round as Chrome rounds the screenshot.
- The streaming encoder was given the composition's size instead of the output size on both streaming paths (`renderOrchestrator.ts`). 4K never noticed, as both sizes are even; at 480p the encoder skipped its even-size pad and libx264 refused an odd frame (`width not divisible by 2 (853x480)`). It now gets the output size, as the disk-frame encode already did.
- The paths that refused DPR > 1 (BeginFrame, drawElement, the Linux fast-capture gate) now refuse any DPR other than 1, since none of them honor a scale; scaled renders take the screenshot path, as 4K does.
- `render/outputScaleRoute.ts`: the layered compositor (HDR content, and shader transitions in webm and mov) sizes its layers and encoder from the composition and never scales, so a scaled output on that route now stops with a named error, checked where every route and replan is settled (`syncCapturePlan`, beside motion blur's route check). Before, a 1080p request from a 4K composition with shader transitions as mov would have encoded 3840×2160. HDR with `--resolution` was already refused in preflight; 4K on this route had the same gap on main and gets the same error.
## What I measured
- Real renders from source on a Linux box (`bun src/cli.ts render registry/examples/nyt-graph --resolution 720p|480p|1080p`), checked with ffprobe: 720p `h264, 1280x720, yuv420p, 15.0 s`; 480p `h264, 854x480, yuv420p, 15.0 s`; 1080p unchanged at 1920x1080. A frame of each, looked at: same chart and layout, crisp text, and the 480p right-edge column is the page's own color (250,248,242), not a pad.
- Before the encoder-size fix the 480p render failed with `[libx264] width not divisible by 2 (853x480)`; after it, it renders.
- `outputScaleRoute.test.ts`: the real route choice for a 4K composition with shader transitions as mov (`outputSupportsPageSideShaderCompositing`, `shouldUseLayeredComposite`, `createCapturePlan`, `resolveDeviceScaleFactor`) lands on `hdr_layered` at scale 0.5 and is refused. CLI preflight and the compile stage both refuse `4k` on a 1922×1080 composition.
- fails without the fix: without the same-tier rule, the preflight and compile tests for 1922×1080 at `4k` pass the render through at 854×480; without the route check, the mov test does not throw.
- At d33c4458: producer `outputScaleRoute` + `compileStage` 18/18 three runs in a row, `shared` (bun) 9/9, cli `render` 104/104 once and its new test three runs in a row; tsc clean in producer and cli. Earlier at e72f6507: parsers `outputResolutionCompatibility` 20/20, core `index` 26/26, producer `resolveDeviceScaleFactor` 14/14, cli `render` + `parseOutputResolution` 122/122, studio-server `render` 53/53. The new cases fail on main (the presets don't exist; smaller presets are refused). tsc clean in parsers, engine, producer and cli; oxlint and oxfmt clean.
## What I did NOT exercise
- Distributed (Lambda / Cloud Run) renders at 720p/480p: the chunk worker's sizes round the same way, but I did not run a distributed render.
- Studio's render queue keeps its own copy of the rule (`RenderQueue.tsx` `scaleApplies`) and offers no 720p/480p option; unchanged here.
skills update (bare or named) and bare skills now exit 0 with a one-line
notice instead of installing or pruning when HYPERFRAMES_SKIP_SKILLS=1, so a
pinned skills install survives the router's trigger-time update. Closes#5695.
* fix(cli): timeline lists clips nested in a timed element and lint flags ones that never show
* docs(lint): wrap the nested-clip entries
* docs(skills): format the nested-clip note and refresh the skills manifest
* fix(cli): keep timeline edits from colliding with a clip's own wrapper
* fix(cli): cut clips nested in a wrapper at their sub-composition's in-point
* refactor(lint): split the nested-clip visibility checks to keep the audit green
* style(cli): restore the timeline test's formatting
* fix(cli): check's dense geometry seeks stop waiting for video frames they never read
* test(cli): race the dense seek against the barrier ask instead of a timer
* fix(cli): keep the geometry seek's comment share at its base
* fix(cli): dense geometry seeks still wait for frame sources, only video frames are skipped
* fix(cli): page loads stop timing out while a busy machine's Chrome warms up
* fix(cli): keep the page-load helper comment-free and its files in the bench filter
Each case left the CLI's background imports in flight. Under load they resolved
vitest's pending mock queue at the same time as the next case's import, which
then loaded the real command module. Wait for dynamic imports to settle before
resetting the mocks.
* feat(cli): judge text behind a transparent video by its decoded alpha in check
The layout audit treated every <video> as opaque over its whole box, so a
caption between footage and a remove-background cutout always failed
text_occluded and needed data-layout-allow-occlusion, which also hid a word
the subject's head fully covered.
check now draws the video's current (seeked) frame into one reused,
downscaled scratch canvas, once per sample and only for a video a text probe
lands under. A fully opaque frame keeps today's behaviour. A frame with
transparency is judged per rendered word against its alpha: partial cover is
an info finding carrying the most covered word's share, and a word 80% hidden
or two neighbouring words each half hidden is an error. A frame that cannot
be read falls back to opaque with a video_alpha_unread info note.

* test(cli): serve the video-alpha fixtures from memory, not request paths
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(cli): check finds words under narrow, mirrored or backed cutouts
Review follow-ups on #5657:
- A matte the probe walk passes over, even at clear-alpha points, now triggers
the per-word check, so a feature between two probe columns (an arm, a mic
stand) still fails the word it hides.
- Mirrored videos and images map viewport points through the flip; a rotated,
skewed or 3D-transformed video falls back to opaque with video_alpha_unread.
- A video with an opaque CSS background keeps its whole box occluding.
- cli.mdx lists every unread cause and why a fully transparent frame is one.

The skill hash walked every file in a skill directory, so Python
__pycache__/*.pyc left by running a skill script (or node_modules, editor
swap files) changed it. Locally gen-skills-manifest then wrote a hash CI's
clean checkout could not reproduce, and an installed skill that had run a
script read as outdated forever. Skip those by-products on both the source
and the installed side so the hash stays a function of authored content.

* feat(cli): render telemetry reports how busy the machine's CPU was
render_complete and render_error now carry system-wide CPU busy share (average
and busiest 2 s window), cores busy in that window, and the one-minute load
average at start and end, for CLI and Studio renders. Nothing is sampled when
telemetry is off.
* test(cli): render tests use a private project folder instead of /tmp/project
* feat(cli): the api provider speaks the HeyGen audio analysis contract
The api rung now sends its key as x-api-key, a new Idempotency-Key on each
request, and 16 kHz mono 16-bit WAV: the channels are averaged and resampled
with a windowed sinc whose cutoff sits under 8 kHz, so nothing folds back in.
It reads the answer from a { "data": ... } envelope, or bare. Times stay in
seconds, and the answered times still snap onto beats measured on the signal
as decoded. The response type gains time_resolution_seconds.
* fix(cli): reject redirects from audio analysis requests
* fix(cli): preserve audio when stereo downmix cancels
* feat(cli): audio answers beats, downbeats, bpm, sections and describe through a provider ladder
Beats and downbeats try api, apple-mu, beat-this, then signal; sections try api, apple-mu,
then signal; describe tries api, then apple-sound. bpm is read off whichever provider placed
the beats. Each provider says whether it can run here and why not, and the ladder warns
when it passes one over.
The signal rung is a TypeScript tracker: log-band spectral flux, autocorrelation tempo with
a log-normal prior, Ellis dynamic-programming beats with a windowed local tempo, a low-band
bar phase, and Foote novelty sections snapped to beats. It reports no steady beat when the
onsets do not repeat.
The api rung posts the audio to HYPERFRAMES_AUDIO_API_URL with HYPERFRAMES_AUDIO_API_KEY and
moves each answered time onto the nearest signal beat within a quarter beat, reporting what
moved and what did not. beat-this runs Beat This! from a configured Python and local weights
and never downloads. apple-sound runs macOS's sound classifier through a Swift helper.
apple-mu reports that Music Understanding needs macOS 27.

* docs(cli): audio's beats, downbeats, bpm, sections, describe and their provider ladder
* feat(cli): beats tracks the music with the TypeScript beat tracker, without Chrome
hyperframes beats and Studio's beat detection now share analyzeMusicFromSignal: band energies,
then the spectral-flux tracker in audioRhythm.ts, then each beat's loudness for its strength.
The CLI decodes with the same ffmpeg path as hyperframes audio, so beats no longer launches
headless Chrome. Studio still decodes in the browser and passes every channel.
The old analyzer averaged bpm-detective's tempo with an energy-peak tempo it had only compared
after folding both into one octave, and phased a rigid grid from noisy peaks. On 22 real tracks
with exact script grids it found the tempo 18% of the time with beat F 0.437; this finds it
91% of the time with F 0.887, and refuses the other two rather than guess.
Below a tracker confidence of 0.2 no beats are reported, so ambient or rubato music gets no
invented grid and the CLI still writes nothing. bpm-detective, the energy-peak grid, the
headless analyzer and its prebuilt bundle are gone.
* fix(core): tempo reads 96 BPM off beats on 10 ms frames, not 95.2
The tracker places beats on 10 ms frames, so a 625 ms beat lands 620 or 630 ms apart and the
median interval reported 95.2 or 96.8 BPM. Tempo now averages the intervals within 10% of the
median: as robust to a skipped or doubled beat, without the frame-sized step. Both
hyperframes audio and hyperframes beats read it.
* fix(cli): remove redundant audio context comment
* fix(core): remove redundant tempo interval comment
* fix(ci): record beat analyzer removals and browser evidence
* fix(core): keep flat audio novelty in one section
* chore: keep PR capture evidence out of the source tree
* fix(cli): honor BPM provider pins before analysis
* feat(cli): audio answers beats, downbeats, bpm, sections and describe through a provider ladder
Beats and downbeats try api, apple-mu, beat-this, then signal; sections try api, apple-mu,
then signal; describe tries api, then apple-sound. bpm is read off whichever provider placed
the beats. Each provider says whether it can run here and why not, and the ladder warns
when it passes one over.

a log-normal prior, Ellis dynamic-programming beats with a windowed local tempo, a low-band

* feat(cli): hyperframes audio measures where sounds land, in film time
Adds @hyperframes/core/audio-analysis: an energy envelope, spectral-flux
and energy onsets, the moments a sound lands (onset, steepest rise, peak,
tail end), BS.1770 loudness with true peak, silence spans and a first
guess at sfx/voice/music, all pure functions of PCM. Each capability runs
through a provider ladder so model or service providers can join later.
The radix-2 FFT moves out of audioCarve so both share it.
`hyperframes audio` decodes with FFmpeg and analyzes files, or the film's
own audio and video clips by element, second, range or boundary, reading
only the part of each file that plays. Timeline rows now carry
`mediaStart`, moved by an in-point host's cut, so file time maps to film
time.
* feat(cli): audio placements carry the element's own data-start, local to its composition
* feat(cli): audio placements carry the element's own data-start, local to its composition
* feat(cli): audio places a file with --place-at, drops --boundary
--start becomes --place-at and --media-start becomes --skip-file-seconds,
which only goes with --place-at, refuses to skip the whole file, and warns
when the skipped part held the file's loudest moment. --boundary is gone:
--at and --range cover the sounds a cut touches.
* fix(cli): pass a sound file to ffprobe as a file, on every platform
ffprobe treated a name starting with a dash as an option because the argument
list never ended the flags. The path check compared a Windows drive path to a
POSIX string, and a new timeline comment raised that file's comment share.
* fix(cli): hear a reversed stereo channel, and warn when its peak was skipped
Averaging the channels cancelled a reversed one, so a real hit was reported
as silence. The skip warning also compared against the decode margin, so a
peak just before the kept window produced no warning.
* fix(cli): report spend usage for Claude plans without rate windows
Spend-metered Claude plans (for example Enterprise) return null five_hour
and seven_day windows from the OAuth usage endpoint and put their allowance
in spend / extra_usage instead. The parser rejected every such response as
invalid_usage_response, so `hyperframes usage` always reported unknown.
- Read spend.percent (falling back to extra_usage.utilization) into a new
`spend` window on known results; over-limit spend caps at fully used.
- Report `no_usage_windows` instead of `invalid_usage_response` when a
well-formed response simply has no window.
- Document the `spend` field in the hyperframes-cli skill.
