Extends the studio-preview fix to the render path and the asset-discovery
utilities, which share the same resolver and had the same defect.
`rewriteAssetPath` takes an optional `assetExists` probe. A plain relative ref
authored in a sub-composition (`_shared.css`, `clip.mp4`) is re-pointed at the
composition's own directory when that sibling exists on disk; project-root refs
with no sibling (the registry's `assets/logo.png` convention) stay as authored.
Callers that can see the filesystem supply the probe, so the module stays free
of node:fs.
Also fixes a second defect in the inliner: `<head>` <link> hrefs and external
script srcs are hoisted into the root document but never went through the
rewrite at all, so even the documented `../` form escaped the project and 404'd
at render time.
Wired into the preview bundler, the producer compiler, the studio preview
builder, the HEVC preview lint, the project lint's asset scans, publish proxy
baking, and media-treatment source resolution.
citty parses string options greedily, so a bare --frame-check consumed
the following flag as its value (--caption-zone silently dropped,
--json disabled) and failed with an error blaming --caption-zone.
Normalize rawArgs at the check command boundary (bare --frame-check
followed by a flag or at end becomes --frame-check=), attribute
frame-check spec errors to --frame-check, and detect dash-prefixed
values with corrective guidance.
Fixes#2965
* fix(cli): stop dropping queued telemetry when process.exit races the final flush
Two exit-path defects introduced by the 0.7.65 process-lifecycle refactor:
1. The 'exit' handler returned early once finalizeCli had started, which
also skipped the flushSync() fallback. When an agent-pipe EPIPE killed
the process mid-flush (the NORMAL teardown under Claude Code / Codex),
the still-queued render_complete was silently dropped — fleet delivery
fell from ~90% (0.7.55-0.7.64) to ~35%. flushSync() is now
unconditional: empty queue is a no-op, event uuids dedupe re-sends.
2. The EPIPE handlers set commandFailed unconditionally, so every piped
successful render scored success:false in cli_command_result (fleet
success rate collapsed 89% -> 5-25%). EPIPE now only marks failure
when the pipe died before the render artifact was validated, matching
the existing isRenderSucceeded() exemption on the uncaughtException
path.
Regression tests cover both: flushSync-after-finalize, and EPIPE
before/after artifact validation.
* fix(cli): don't score a validated render as failed due to pre-artifact noise
Review follow-up: commandFailed can be set by noise that precedes artifact
validation — a stray unhandledRejection mid-render, or an EPIPE firing
before markRenderSucceeded on a run that still completes. Once the
artifact validates, that earlier noise must not flip the run's
cli_command_result to success:false. Genuine failures keep a non-zero
exit code and are still caught by the exitCode check.
Extracted commandSucceededForTelemetry() and applied it at both tracking
sites (finalizeCli and the exit handler), with a regression test.
* test(cli): pin the production-reachable producer of the stale-failure override
Review note: the pre-artifact-noise test drives the scenario with an
EPIPE, which only reaches 'render validates afterwards' because
process.exit is mocked — that sequence can't occur in production. Add a
test for the reachable producer: an unhandledRejection before validation
(the handler deliberately does not exit), followed by a validated render,
must score success:true at exit code 0. Verified red on the pre-override
cli.ts.
* docs(prompting): correct workflow one-liners against skill contracts
general-video leads with its positive identity and companion mode;
faceless-explainer keys on invented visuals instead of TTS;
talking-head-recut uses the 'graphic overlays' trigger term;
motion-graphics gains its input side and overlay output;
music-to-video stops implying images are required.
* docs(prompting): make vocabulary video grids readable
Replace the 4-5 column table hack with a 3-column CSS grid,
switch demo clips to autoplay muted loops (no black poster frame,
no player chrome over tiny videos), and align cells at 16:9.
* docs(prompting): document the opening interview and run-shape questions
The guide taught prompt shapes but never prepared readers for the
conversation that follows: the intent interview, the two run-shape
questions (storyboard, automation vs companion), the just-build-it
skip, and BRIEF.md as the resumable artifact. Add that section to the
overview, a disambiguation note on the storyboards page, and free up
'companion' as a reserved term in media-and-audio.
* docs(guides): make BRIEF.md the pipeline's Step 3 artifact
Step 3 (Strategy & Messaging) listed no output while describing
exactly what BRIEF.md now captures. Name the artifact in the step
table, project tree, step body, gate, and iterating list, and fix
SCRIPT.md's step label in the tree (Step 4, not 3).
* docs(quickstart): realign the setup surface with the skills catalog
The quickstart drifted from docs/guides/skills.mdx, CLAUDE.md, and the
prompting overview — it had never been updated when those surfaces were:
- `--full-depth` on both install commands, with the reason inline. Without
it `skills add` fetches the skills.sh registry blob, which lags `main` by
hours, so a reader following the quickstart installs stale skills.
- `check` in the `/hyperframes-cli` row, and a validate step in the manual
dev loop, which went preview → render with no gate at all. The prompting
overview calls `check` "the step people skip and regret" and states both
`lint` and `check` must pass before rendering.
- `/hyperframes-keyframes` in the core-skills table (8 rows → 9).
- `/figma` in the optional-workflow list (10 → 11).
* docs(skills): close the catalog drift class and complete the music-to-video input
Follow-up on the two review nits from #2872.
`/music-to-video`'s SKILL.md names three inputs — an audio file, a video to
pull audio from, or a track generated from a mood brief. Every compressed copy
of that description carried only the first two, and the third is the one that
makes "a complete video needs zero assets" true. Fixed on all eight surfaces
that state it, so no surface is now more correct than its siblings: the
prompting overview and quickstart setup tables, docs/guides/skills.mdx, the
README catalog, root CLAUDE.md + AGENTS.md, both CLI project templates, and the
router's own routes/music-to-video.md Input line (whose Interview must-haves
already listed all three).
The drift was structural, not accidental: the sync set declared in
docs/guides/skills.mdx and in CLAUDE.md's "Skill catalog maintenance" named
four surfaces and never the two setup tables, so those two were free to rot
while the declared four stayed correct. Both declarations now name them, and
both say the set applies to a *changed contract* — a reworded description —
not only to an added or renamed skill.
skills-manifest.json regenerated for the touched route file.
* docs(claude): point the routing-surface rule at routes/, not the moved stubs
Item 3 of "Skill catalog maintenance" still sent readers to
`references/workflow-catalog.md` for a workflow's input/output/trigger
contract and `references/route-briefs.md` for its interview entry. Both are
now "moved" stubs — the contract and the interview entry live together in
`references/routes/<workflow>.md`, one read per candidate route.
Same failure class the previous commit fixed at item 1: a maintenance rule
outliving the layout it describes. Swept the tree for other pointers at the
two stubs; there are none, so this closes it rather than fixing one instance.
* fix(capture,audio): three defects found running product-launch-video end to end
Found while running the full product-launch-video workflow twice against a real
site (linear.app) to verify PRs #2880/#2881/#2882. All three are independent of
those PRs.
**Scraped SVGs were unusable as files.** `assetDownloader` wrote an inline
`<svg>`'s `outerHTML` straight to `assets/svgs/*.svg`. An inline SVG inherits its
namespace from the HTML parser, so `outerHTML` omits `xmlns` — valid pasted back
into HTML, but not a standalone document, and `<img src="logo-abc.svg">` renders a
broken-image icon. That is exactly how these assets get consumed. `toStandaloneSvg`
now declares the namespace on the way to disk (plus `xmlns:xlink`, but only when an
`xlink:` attribute is actually used). The filename hash moved to the bytes that
land on disk so it still cannot drift from content.
**`sfx: none` became a cue named "none".** `fetch-sfx` split the storyboard's
`sfx:` list and dropped only empty strings, so the absence marker reached the
engine as a real cue that could not resolve. The absence spellings are part of the
storyboard vocabulary; drop them.
**`bgm_pending` was lost translating neutral meta to product-launch meta.** A
detached Lyria/MusicGen generate leaves `bgm: null, bgm_pending: true` until the
track lands. `toProductLaunchMeta` returned only `{bgm, voices, sfx}`, so "not
ready yet" became indistinguishable from "silent by design" — and because
`fetch-sfx` rewrites `audio_meta.json` from the sidecar, a still-generating bed was
snapshotted away with nothing to signal it. The flag now survives, and `fetch-sfx`
warns when it snapshots a pending bed instead of leaving a silent film that the
storyboard claims has music.
Not included, deliberately: `assemble-index.mjs` rewrites `index.html` wholesale
and so discards the block `transitions.mjs inject` wrote, meaning any Step 6 rework
silently loses transitions. Fixing that means deciding whether assemble preserves an
injected block or inject becomes re-appliable — it touches both scripts and the
Step 5/6 ordering in SKILL.md, so it deserves its own change.

* feat(capture): re-add the full-page plate a scroll shot needs, at 1x
`product-launch-video` tells a scroll shot to animate a viewport over a full-page
capture. No such file existed: capture emits 15 viewport-sized scroll-position
tiles, and a plate is not substitutable by tiles — a viewport travelling down one
continuous image is the whole point.
An earlier `full-page.png` was dropped in 62b55171e because 1/8 agents read it and
the contact sheet covered the same ground. That measured it as a *comprehension*
artifact, on an eval where nothing was building scroll shots. The scroll shot is a
different consumer, so this brings the plate back — but not as it was, because two
things have to hold for it to be worth having:
- **Taken last.** After the scroll traversal, so lazy images have loaded and
scroll-triggered reveals have fired. A plate shot on arrival is full of blank
bands, which is a good reason for an agent to look once and never again.
- **Sticky chrome neutralised.** `fullPage` bakes a fixed header in at one
position, freezing a nav across the middle of the plate. The viewport tiles keep
sticky on purpose (natural browsing state); the plate cannot. Positions are
recorded and restored in a `finally`, so the extraction passes that run afterwards
see an unmodified DOM.
**1x, deliberately.** 2x is what you'd want to push in without softening text, but
doubling a long marketing page passes Chrome's 16384px screenshot cap precisely on
the pages that most want a scroll shot (linear.app: 10962 CSS px → 21924 at 2x). At
1x a 1920-wide plate is pixel-exact for a 1920x1080 viewport. A frame that needs
headroom captures its own region at 2x instead. Pages over the cap get no plate
rather than a silently clipped one, and the caller falls back to the tiles.

* docs(product-launch-video): point the scroll shot at the plate, make handoff fields binding
Two follow-ups from the same end-to-end runs, now that #2880 and #2881 have landed and
their sentences exist to edit.
**The scroll shot pointed at an artifact that did not exist.** #2881 said "use a 2x
full-page capture and animate the viewport over it". Neither half held: capture emitted
no full-page image, and 2x on a long marketing page passes Chrome's 16384px screenshot
cap precisely on the pages that most want a scroll shot. Both runs watched the agent go
looking, not find it, and improvise — once by re-capturing 2x strips per section, once by
using the native 1920x1080 tiles full-bleed. This PR's capture commit adds the 1x plate,
so the sentence can now name something real: the plate, its absence on pages too tall to
capture in one piece, the tile fallback, and why pushing in past 1:1 still wants a region
capture of its own.
**A constant field was being read as an absent one.** #2880 asks for x/y, scale, opacity
and direction/speed on every handoff. Across two runs on the same model, `opacity` went
0/12 then 12/12 — when the value never changes, leaving it out is a reasonable reading of
the instruction. But downstream an omission and "there is no handoff here" are the same
thing, so the field set has to be stated as binding even when constant. Same clause added
to the worker's side of the contract.

* fix(capture,audio): close the three contract gaps raised in review
Review on #2892 (Rames, Magi) found the fixes correct inside the changed files but
incomplete at the contract level. All three hold up against source; two of the three
were reachable in production, and the plate one was self-inflicted by this PR.
**The plate guard checked a stale height.** `scrollHeight` was measured before the scroll
traversal and handed to the guard, but the plate is deliberately shot *after* it so lazy
content has loaded — and lazy loading grows the document. The guard's input therefore read
low on exactly the long pages it exists for, letting the check pass and a clipped plate
through, undetectable downstream because the skill only teaches the tile fallback when the
file is *absent*. `captureFullPagePlate` now measures the height itself at call time, and
verifies what Chrome actually produced by reading the PNG's IHDR before writing, since the
capture can trigger another round of loading. Over the cap, nothing is emitted.
**Assembly dropped the flag again.** `bgm_pending` survived into `audio_meta.json` but
`assemble-index.mjs` rebuilt its audio object from three named keys, so at the step that
actually builds the film "not ready yet" still looked like "silent by design" — this PR's
own framing of the defect, one layer further down. The flag rides along now, and a pending
bed with no file raises an anomaly instead of quietly assembling a silent cut against a
storyboard that promises music.
**The sibling adapters had both audio bugs, and there were two of them.** The review named
`faceless-explainer`; `pr-to-video` carries the same file. Its own test asserts the two are
byte-identical ("intentionally identical across the reusing skills"), so fixing one alone
broke that test — which is what caught the second copy. Both now carry the absence-sentinel
filter and the surviving `bgm_pending`, and `faceless-explainer` gets the same five
regression tests.
Also from review (Miga): the sticky-restore in `finally` is wrapped, so a page that broke
mid-capture cannot replace the real error with a cleanup one.

* fix(capture,audio): meet the two review asks I under-delivered on
Follow-up to 194fb6995. Re-read Magi's review body rather than working from the summary,
and two of the three blockers were addressed in spirit but not to the letter.
**The plate probed before neutralisation, not after.** 194fb6995 moved the measurement off
the caller's stale value and into the function, but took it before forcing fixed/sticky
elements to `static`. The review called this out specifically and is right: dropping those
elements back into flow grows the document, so the probe could still read under the cap on a
page that is over it once neutralised. The probe now runs after neutralisation and before the
shot, inside the same `try` so restoration still happens on the early return. Added the exact
case asked for — initial height under the cap, final height over it — asserting no
screenshot is taken, no file is written, and the page is still handed back unmodified.
**Assembly warned where the review asked it to refuse.** An anomaly in a list is not
enforcement: assemble is re-run on Step 6 rework, long after the audio step's warning
scrolled past, and a warning still lets a silent film out the door over a snapshot whose own
JSON says the bed is generating. `assemble-index.mjs` now dies on `bgm_pending && !bgm`, with
`--allow-pending-bgm` as the deliberate escape for previewing mid-generate. Pinned with three
tests in a new `assemble-index.test.mjs`: refusal writes no index.html, the escape assembles
and says so, and a film that is silent *by design* still assembles untouched — the
distinction the flag exists to make.

* fix(audio): carry the bgm_pending gate into the sibling assemblers
The remaining blocker, and one this PR created: the previous commit made all three copies of
the audio adapter *emit* bgm_pending, but only product-launch-video's assembler *reads* it.
So faceless-explainer and pr-to-video would do exactly what this PR set out to stop — parse
an audio_meta.json that says the bed is still generating and assemble the silent film without
a word. Producer fixed in three places, consumer in one, is worse than neither: before this
PR there was no flag to drop.
Both siblings now get the same three changes product-launch-video got — the flag carried
through the audio object, `die` on `bgm_pending && !bgm`, and `--allow-pending-bgm` as the
deliberate escape — plus the same three tests: refusal writes no index.html, the escape
assembles and says so, and a film that is silent *by design* still assembles untouched. That
last one is the one worth having; it proves the flag restored a distinction rather than just
adding a gate.
Applied as three separate patches rather than a file copy: these assemblers have diverged
(pr-to-video validates a bare `<template>` fragment where product-launch takes a `<div>`
root, which its fixture reflects).
`music-to-video` has the fourth copy of this assembler and is deliberately untouched: it has
no audio producer, and its assembler reads `{ voices: [] }` with no bgm path at all, so the
flag can never reach it.

The short-comp routing gate can only read a live element count when a
probe session exists, and the first v0.7.83 data shows that is far rarer
than estimated: 17% of renders (86/503), not the ">=28%" the video-presence
proxy suggested. The other 83% fall back to a static source scan, which
is exactly blind to the shape that motivated the live count — small
markup, thousands of script-created nodes.
That leaves the fleet element-count distribution unknowable for most
renders, and the observed distribution is already surprising: p99 ~900,
max 1,420 against a 2,500 ceiling calibrated on 7k/20k/40k synthetic
nodes. Either the ceiling is close to irrelevant, or the large-DOM tail
is hiding in the 83% we cannot see. Both readings change what PR B
should do, and neither is decidable from probed renders alone (they are
a biased sample — they got a probe *because* they carry media or
unresolved compositions).
So measure it where every render already goes: capture-session init.
`collectSessionInitTelemetry` gains a querySelectorAll("*") count beside
the tween count it already collects, riding the same channel to
`observability_init_element_count`. This is observational only — capture
has begun, far too late to route on — and it deliberately does not feed
the gate. It answers the distribution question the gate cannot.
Coverage for this channel is proven rather than assumed: the tween-count
fix that shipped in v0.7.83 took the clamped-parallel bucket from 0/272
renders to 217/217, and 23.1% -> 100% overall.

R4 review finding, and the comment I wrote in R3 was simply wrong: the
probe session is NOT running for every render. probeStage's needsBrowser
gate launches one only for unknown duration, unresolved compositions, or
specific media cases — and hasRuntimeInsertedMedia matches only
createElement("video"|"audio"), never createElement("span"). So the exact
shape that motivated the live-DOM fix (a known-duration, media-free
caption comp building thousands of nodes in script) gets NO probe, falls
back to the static source scan, reads as ~2 elements, and could enter the
applied cohort at 40k live nodes. The R3 fix measured the right thing but
only for the population that already had a probe.
Now the count carries provenance and the band fails closed:
- resolveCompositionElementCount returns { count, source: "live" |
"static" }. Only "live" — an actual DOM measurement — may open the band.
- resolveDeShortBand gains a third decisive outcome, "unmeasured", for
the static case. It deliberately does NOT report skipped_elements: a
static undercount is not a real oversize observation, and putting it in
the control arm would contaminate the DiD just as putting it in the
treatment arm would. Neither cohort; never routes.
- composition_element_count_source ships alongside the count, so the
fleet rate of "static" sizes the population a future
conditional-probe-launch would unlock — which is the data PR B needs to
decide whether that launch cost is worth paying.
Regression coverage walks the real chain rather than a full render, using
the production functions in pipeline order: probeRequiresBrowser (newly
extracted from the inline needsBrowser expression, so the gate is
testable at all) returns false for the caption-comp shape → the resolver
reports static and a count under the ceiling → the band reports
unmeasured, not applied. Fault injection confirms it bites: removing the
one guard line fails exactly these three tests.

Both reviewers (Rames, Magi) independently flagged the same thing: by the
time the return statement executes, hadFired is always false — the guard
above already returns early for every case where hadFired was true. The
merge expression wantFired || hadFired || undefined was defensively
correct but misleading; it reads as "OR the two together" when the
function has already established only one of them can be true here.

The routing surface the short-comp benchmarks validated is (motion x DOM
size x frames). After the baseline release, fleet telemetry carries DOM
size (composition_element_count) and frames on every render — but the
motion proxy, observability_init_tween_count, has 0% coverage on the
exact renders the band routes: parallel workers' console buffers (and so
the [FrameCapture:INIT] line the summary parses) only propagate to the
orchestrator on FAILURE. Single-worker screenshot renders report it;
the multi-worker clamp bucket never does. Verified against 7d of fleet
data: 35k screenshot renders carry tween counts, 0 of 9,600 band renders.
Fix rides the one channel parallel workers already return on success —
the per-worker CapturePerfSummary. Sessions record initTelemetry on
every init path; the perf summary now carries it; the orchestrator
max-merges across workers (same multi-session semantics the console
parser uses) and feeds it to the observability summary as a structured
fallback, console lines still refining when present.
With this, every band render carries full coordinates — (elements,
tweens, frames, path, speed) — which buys two reads: regressing wild DE
speed against element count on the existing 900+ inversions validates
the bench's 0.50ms/element slope BEFORE the routing flip, and any
post-flip misroute can be reproduced locally by feeding its telemetry
row straight into gen-crossover-comp's knobs (--movers ~ tween count,
--static ~ element count) and re-benching.
(Also drops a now-stale fallow suppression in render.ts — the test-only
reset export it guarded gained real test importers, so the issue it
suppressed no longer exists and the gate flags the leftover.)

Two routing surfaces pointed agents at media "policies" and "contracts" without
naming a file. An agent that goes looking and finds nothing fills the gap with
an invented rule.
- skills/hyperframes/SKILL.md: "Load its media-treatment policy" now names
references/media-treatments.md and states the policy governs how footage is
treated, never whether media may be used.
- skills/general-video/SKILL.md: "adoption, resolution, provider, provenance,
and reuse contracts" now names references/resolve.md and
references/setup-providers.md. Drops "provenance", which is ledger
bookkeeping in operations.md, not a contract to follow.
- The scaffolded project templates carried the same unnamed pointer and ship to
every hyperframes init; both updated and kept byte-identical.
31% of fleet renders (24h, v0.7.78+) are DE-eligible comps clamped to
parallel screenshot purely because they sit under the 900-frame inversion
floor — the median fleet render is ~250-600 frames, below every DE entry
threshold. This opens a 250-899 frame band, gated on composition size.
Measured, not assumed. A controlled sweep (fixed synthetic content,
{250,400,600,900}f, single-DE vs parallel-screenshot-W4, 3 reps, capture
mode verified per row, AC power, load-gated) showed single-DE winning
1.16-1.24x at every size — but only for content in constant motion. A
follow-up 2x2 found motion and DOM size pull in OPPOSITE directions, so
neither alone predicts the winner (ratio = ss4/de1, >1 means DE wins):
24 movers / 0 nodes -> 1.05
320 movers / 0 nodes -> 1.24
320 movers / 7000 nodes -> 1.09
24 movers / 7000 nodes -> 0.96
24 movers / 20000 nodes -> 0.71
24 movers / 40000 nodes -> 0.55
DE's wall-clock scales ~0.50ms/element against parallel screenshot's
~0.22ms — drawElement repaints the whole tree per frame while fan-out
amortizes it — so the downside is NOT bounded and a bare floor drop would
have handed a 1.8x regression to large comps. Since motion only ever helps
DE, an element ceiling calibrated at the lowest-motion case is safe at
every motion level; crossover there is ~3.9k, and the default sits at 2500.
The predicate is untouched; the call site picks the floor. Above the
ceiling, or at 900+ frames, behaviour is bit-identical to today — the
change can only add inversions in the new band, never remove one.
Instrumentation, since this ships at full exposure rather than cohorted:
`composition_element_count` on EVERY render (the fleet distribution of the
gate variable is unknown — without it we cannot tell whether 2500 opens the
band for most short comps or almost none, nor re-derive the threshold from
real content), and `de_short_band` = applied | skipped_elements, unset when
the frame count made the band irrelevant, so a fleet perf shift is
attributable to this change rather than to content mix.
Safety is unchanged and already proven on this path: per-frame PSNR
self-verify with screenshot fallback, exactly as the 900+ band has shipped
default-on. Knobs: HF_DE_SHORT_MIN_FRAMES, HF_DE_SHORT_MAX_ELEMENTS (0
disables the band).

The DE parallel-router breaker's tripped state lived in the same config
file as the install id, so the most common identity reset — deleting
~/.hyperframes — also re-enrolled the machine into an experimental path
that had already failed on it.
Mirror exactly two facts into a machine-local state file
(~/.local/state/hyperframes/install-state.json) that a config wipe does
not touch:
- markerAt: written unconditionally on every install, so the fraction of
fresh mints that find it directly measures recoverable id churn
(config wiped, machine persisted) vs unrecoverable (fresh
machine/container/new user). Emitted as install_predecessor_found on
telemetry events; absent (not false) on configs predating the field.
- deParallelRouterTrialFired: a breaker tripped by a previous install
stays tripped for the new one. Config corruption takes the same mint
path, so it survives that too.
The file deliberately holds NO identity — no anonymousId, no counters.
A wiped config still gets a fresh id unconditionally; only the safety
fact about the machine survives. Sync happens inside writeConfig so no
breaker write site can forget it; failures are swallowed (telemetry
must never break the CLI) but leave the memo unset so a later write
retries. `hyperframes telemetry` lists the state path for transparency.
