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.

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
