* fix(core): Safari audio that sits frozen after its cut is pulled onto the playhead in 0.4 s, not 1 s
* fix(core): shorten the frozen-audio comment
* fix(core): leave a WebKit audio element that is still filling data out of the frozen rule
* fix(cli,skills): say a step's credits are its total, and keep cost out of retries
An out-of-credits refusal named what the step needs, and an agent read
that as the shortfall. It now says the number is the step's total.
After its last try, an agent told the person what was spent and what
another try would cost. The HeyGen reference now says not to.
* fix(cli): plan avatar credits from the HyperFrames price rows
An avatar's credits came from its old API price, about five times what
the plan charges, so --max-credits refused calls that fit and a top-up
asked for too much. They now use the Avatar IV photo row plus the
general avatar video row, 950 credits a minute.
* fix(cli): pin the avatar price test and keep pricing under the comment share
* fix(cli): plan avatar seconds on the Avatar IV row alone
The general avatar row is only checked at admission and billed on
seconds left after Avatar IV, so adding it to every second made a 15 s
script plan at 238 instead of 200 and a 220 limit refuse a call that fits.
* feat(skills): creator templates on the HyperFrames plan
A Pro account asks for a video in a creator's format and the agent pulls that
template on demand. The packs sit in the private bucket behind the plan-gated
bundle route, so a Free account gets a 402 and the upgrade step. A pull costs
no credits; making the film spends them as Reverse does.

References in a composition's <template> were never rewritten, because the DOM

as a mention too. A 5-minute presented film went from 196 MB to 71 MB.

The background-removal route dedupes on the body's request_id and ignores the Idempotency-Key

body for such a route. Uploads typed every non-MP4 file as audio, so WebM and MOV inputs were
refused: they now take their type from the extension. Fails without the fix: the new cutout test
in generate.test.ts sees audio/mpeg for WebM and MOV.

* fix(core): keep overflowing content and SVG clip paths in motion-blurred frames
A blurred mover was copied only within its own layout box, so text wider
than the box (a one-line wordmark in a fixed-width container) was cut in
blurred frames. The movers-alone capture also hid every non-mover, including
the SVG clipPath a mover references, which empties the clip and makes the
mover vanish. Both showed as flicker during playback and in full renders.

* fix(core): measure overflowing text with a Range, ignore rects inside the mover
A block child is as wide as its mover however long its no-wrap text, so
reading child boxes missed the common overflow layout. Read the text's own
rects through a Range. On a rotated mover each child's upright client rect
covers the mover's corners, which doubled the box at 45 degrees and could
pull a neighbouring mover into the trail; only rects that leave the
mover's own client rect now grow it.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(core): measure a rotated mover's overflow unrotated
The upright client rect of a rotated mover has empty corners, so overflow
that landed there passed the "stays inside" check and was still cropped.
Measure a rotated mover with its own transform off and map the rects back
through its layout pose, then restore its style.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(core): keep a rotated mover the containing block while measured
With only transform: none, a mover with no position stops being the
containing block of its absolute and fixed children, so they jump to an
outer ancestor while measured and their real overflow is cropped. Add
will-change: transform during the swap, and skip the swap when the mover
has no transform of its own.

* style(core): shorten the overlap comment
* refactor(core): the overlap span names its fields and carries no comments
* fix(core): motion blur notices a WebGL canvas the Studio page touched first
When a same-origin host page (Studio) reaches a preview element before the
scene does, for example through a MutationObserver record, Chrome gives that
element the host's prototype. The scene's getContext("webgl") then ran the
host's unpatched getContext, so the canvas never reached the accelerated
canvas set, capture motion blur stayed on, and the WebGL canvas froze during
preview playback.
The tracker now records a canvas in the set of the canvas's own window, and
installs itself in a same-origin parent too, compiled with the parent's own
Function. Cross-origin parents are skipped.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(studio): track accelerated canvases in Studio's window, not the embedder's
The preview runtime no longer installs the canvas tracker in its parent
window. That ran on every preview boot, so any same-origin page embedding
the player got its getContext wrapped, and a host CSP without
unsafe-eval reported a violation on each load. Studio now installs the
tracker in its own window when its Player module loads, and core
exposes it at @hyperframes/core/page-motion-blur.

* fix(core): a motion blur worker starting mid-film keeps the right state
The mover scan walks the whole film with callbacks live, then seeks back to
the worker's start. GSAP fires one-off calls in both directions, so a worker
starting between two calls took the later call's state and held it until the
next call. Going through 0 first gives every worker what frame 0 sees.

* fix(core): motion blur preview no longer slows down later in the timeline
With data-motion-blur-events="on", which Studio's Subtle and Strong write,
both blur tiers ran timeline callbacks at every per-frame pose read. Each
frame's reads step back from half a shutter ahead to the frame, so a
callback that keeps state and replays from zero on a backward seek (a
ripple simulation, for example) redid its whole history most frames, and
the cost grew with the playhead.
The mover scan still runs callbacks, so motion set from a render(t)
callback is still found. With events on, it also scans once without them,
and the per-frame reads run callbacks only when the two scans disagree.
The eventful scan runs first, so tweens take their start values after the
callbacks before them and a one-off call fires as often as before.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(core): motion blur reads run callbacks when a callback moves any box
Comparing which elements each scan finds missed a callback that pans a
mover's ancestor while a tween also changes that ancestor: both scans
found the same movers and the same changing elements, so the reads left
the pan out. The scans now compare every changing element's box at each
step, and the reads run callbacks when any step differs.
Raises @hyperframes/core's unpacked size budget to the measured size plus
the usual 5%: main already sat 0.98% over the old budget, and this change
adds 1,232 bytes, which tipped it past the 1% tolerance.

* fix(core): silent motion blur reads land back on the frame as its own seek left it
After silent pose reads, the restore seek back to the frame left GSAP in a
different state than the frame's own eventful seek did:
- A step exactly on the frame (a .call() or set) was re-armed, so the next
frame fired it again. Calls fired 2-5 times per crossing, and a toggle
could end inverted.
- In renders, which keep no GSAP structure, landing back on the frame from
later skipped same-time steps' authored order, so the frame showed the
first of two sets instead of the last.
Events-off blur always read silently and had both. This PR moves events-on
roots without callback-driven motion (the Studio default) onto that path,
so both are fixed here.
The host's new holdFrame snapshots every landing mark on the root and scene
timelines before the reads, and its restore seeks back silently, redraws in
authored order where there is no structure, and puts the marks back. Each
call now fires once per frame crossing, as without blur, and same-time sets
land as authored.

* fix(core): a held render frame draws its scenes first, so the root lands last
holdFrame redrew the root and then the scenes, the reverse of the frame's
own seek. When a scene and the root tween one property, the frame landed
on the scene's value instead of the root's.
The hold and landing move into the GSAP adapter as holdFrameMarks, which
takes the scenes and the root separately, so the order lives in one place
a real-GSAP test can pin.

* fix(cli): audio windows read beats off the whole clip; beats snap to the signal and mark silence
A film query that covers part of a clip measures beats, downbeats, bpm and sections on the
whole clip and cuts them to the window, as #6653 did for kind, so a window under 6 s still
has its beats.
One step after every provider ladder moves a provider's beats and downbeats onto the
signal's own beats within a quarter beat (the snapping api did alone) and marks each with
`silent`, true where the beat falls in silence. Beats are marked, never dropped; the JSON
change is the additive `silent` array.
— Jerrai
* fix(cli): beats with no pulse are unheard; a window with none answers no steady beat
Review fixes for #6692:
- The per-beat flag is now `unheard` (renamed from `silent`, not released): true in silence
or where no onset falls within 50 ms of the beat, so hiss, room tone or a held pad no
longer pass as beats.
- A window keeps the whole clip's beats only when at least two of its beats are heard;
otherwise it answers "no steady beat" as before, with no downbeats and no bpm.
- A window's bpm is the tempo of its heard beats, never the whole clip's.
- Comment lines trimmed so analyze.ts, run.ts and api.ts are at or under main's share.
— Jerrai
* fix(cli): a beat is unheard only where two beats in a row have no onset
Scored on the ground-truth set, flagging every onset-less beat also flagged heard beats the
onset detector misses: the drop downbeat after a snare roll, single beats under narration,
quiet beats late in a fade. A pulse gap now needs two onset-less beats in a row; hiss, room
tone and held pads span many beats and stay flagged, and silence is flagged as before.
— Jerrai
* fix(cli): a window with no pulse on the clip's grid reads its own beats, as before
Genesis found a window over a section far under the clip's loudest part answered "no steady
beat" where main, reading the window alone, found every beat: the clip's grid and onsets
skip a section that quiet (from about 40 dB under, for clicks). When a window keeps fewer than
two heard beats from the clip's grid, its beats, downbeats and bpm now come from the window
alone, as they did on main. Hiss still answers "no steady beat" on its own.
The hiss test's noise() repeats every 10,466 samples (0.22 s at 48 kHz), which the window's
own reading took for a pulse; that test now uses a xorshift generator.
— Jerrai
* fix(audio): unheard comes from level-free rhythm evidence, so quiet music stays heard
A beat was flagged by an absolute -50 dBFS silence and by onsets under 10% of the clip's
loudest hit, so music 30 dB or more under the loudest part read as unheard. Now:
- core localBeatEvidence reads the cached standardised onset curve over the 6 s around each
beat: the tracker's steady-beat confidence there (clarity at the local beat lag times the
beat's own lift) and the beat's lift over the span's mean.
- A beat is unheard in digital silence (-80 dBFS), or when its span keeps no steady beat
(confidence under 0.15) and its own onset does not stand out (lift under 1.5). Lift alone
keeps beats under narration heard, where syllables lower the span's clarity.
