The on-device index was fetched once and never revalidated: the only freshness check was two existsSync calls. A move added after that fetch was invisible to meaning search permanently, not down-ranked but absent from the candidate set. The registry manifest on the same command carries a 24h TTL, so the two halves of one feature disagreed about staleness. The dropped count reported over-coverage only, names the index has that the registry lacks. Under-coverage was never computed, so the harmless direction was instrumented and the costly one was silent. Reproduced with an index truncated to 120 of 168 moves: dropped read 0, perfect health, while 48 moves were unreachable. Counts under-coverage from the name list the artifact already carries, so no extra request. Warns only when non-zero, and names the remedy. The remedy had to be made true: --on-device could not refresh a stale index because hasLocalVectors short-circuited the fetch. That flag now refetches when the index is absent or no longer covering. Two defects the reproduction surfaced. A failed refresh reported the tier unavailable while the old vectors were still on disk and still ranking. And the fetch wrote its two files one at a time, so failing between them paired a new name list with an old matrix, a hard load error rather than stale data. It now writes both or neither, which matters more once refresh runs on staleness. top_score returns, scoped to the on-device tier and set to the score of the best result actually shown rather than the ranking head, which can describe a row the caller never received. Also: scripts/ is now typechecked. It never was, which is how a build script that crashes after the paid embedding call, and two scripts whose imports do not resolve at all, went unnoticed. 43 errors fixed, no suppressions. And the docs stop describing a --smart hosted tier that was deleted, an item that does not exist, and a registry refresh that cannot fix a stale vector index.
hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio running at http://localhost:3002
npx hyperframes preview --port 4567
render
Render a composition to MP4. Run from the project directory; the positional
argument is the project directory (not a file), so render the project's
index.html directly, or point at a specific composition file with -c:
npx hyperframes render -o output.mp4
npx hyperframes render -c ./my-composition.html -o output.mp4
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
Run rendering benchmarks:
npx hyperframes benchmark ./my-composition.html
doctor
Check your environment for required dependencies (Chrome, FFmpeg, Node.js):
npx hyperframes doctor
browser
Manage the bundled Chrome/Chromium installation:
npx hyperframes browser
info
Print version and environment info:
npx hyperframes info
docs
Open the documentation in your browser:
npx hyperframes docs
upgrade
Check for updates and show upgrade instructions:
npx hyperframes upgrade
npx hyperframes upgrade --check --json # machine-readable for agents
