Run `fallow fix --auto-fixable` to remove `export` keywords from symbols fallow's reachability analysis identifies as unused. Keeps only the cases where the symbol is still referenced internally in its own file (so removing `export` doesn't surface a new oxlint `no-unused-vars` error). Result: fallow dead-code findings drop from 276 → 208 (68 fewer unused exports), with no behavior change — each symbol is still defined and used exactly the same way within its file. Reverted ~20 files where fallow's auto-fix would have created cascading "declared but never used" lint errors — those are cases where the symbol isn't used at all, and properly cleaning them up means deleting the declaration, not just dropping `export`. Better to land that as a separate, narrower PR rather than mixing it into a mechanical de-export. Also reverted four false positives where fallow missed real consumers: - `captureCost.ts` (renderOrchestrator has two separate import blocks from the same module; fallow only saw the first) - `propertyPanelHelpers.ts`, `domEditingLayers.ts` (real internal uses fallow's reachability missed) - `render.ts` (functions imported via `await import()` dynamic import, which fallow's static analysis doesn't follow) Test plan: bun run --filter '*' typecheck (clean), oxlint + oxfmt clean, cli/core/studio/engine vitest suites pass (335 + 917 + 576 + 605 tests).
Hyperframe Runtime Engine
This folder owns the runtime that powers preview and producer parity.
Current Direction
- Runtime source of truth is converging on
hyperframe.ts. - Build produces:
dist/hyperframe.runtime.iife.js(browser bootstrap)dist/hyperframe.runtime.mjs(tooling/tests)dist/hyperframe.manifest.json(version + sha256 + artifact map)
- FE owns iframe runtime injection.
- BE persists raw generated HTML without injecting runtime scripts.
- Producer validates pinned runtime checksum from manifest before render.
Runtime Contract (Stable Surface)
Globals:
window.__playerwindow.__playerReadywindow.__renderReadywindow.__timelineswindow.__clipManifest
postMessage:
- parent -> runtime control:
source: "hf-parent"type: "control"- actions:
play,pause,seek,set-muted,set-playback-rate,enable-pick-mode,disable-pick-mode
- runtime -> parent events:
source: "hf-preview"type: "state"andtype: "timeline"
Determinism baseline:
renderSeekis the producer-canonical seek path.- 30fps quantization and readiness gates are correctness requirements.
Build
bun run --filter @hyperframes/core build:hyperframes-runtime
Security Expectations
- Runtime bootstrap URL must be version-pinned and host-allowlisted.
- Iframe bridge payloads must be schema-validated.
- Unsafe URL schemes (
javascript:and unapproveddata:) are rejected. - Fail closed if runtime bootstrap/handshake is not healthy.
Product Editing Model
- Primary mode: prompt + element picking.
- Secondary mode: manual precision controls.
- Avoid timeline-first manual workflows as default product path.
