## Summary
- Respect `--json` flag on all lint exit paths so agents always get machine-readable output
- Separate `infoCount` from `warningCount` in linter results (was conflated)
- Display `info` vs `warning` severity distinctly in lint output
* fix(lint): detect GSAP animations targeting clip elements (tab crash)
The runtime manages clip visibility via inline styles. When GSAP also
writes inline styles on the same element, both systems trigger style
recalculations every frame, creating a runaway loop that crashes the
browser tab.
New rule gsap_animates_clip_element (error severity):
- Builds map of all elements with class="clip" (by id and class)
- Checks if any GSAP selector resolves to a clip element
- Nested selectors like "#overlay .title" are correctly ignored
- Merged into existing GSAP script loop (no redundant parsing)
* fix: remove non-null assertions and add missing test coverage
- Replace `!` assertions with optional chaining in lint.ts and tests
- Add shouldBlockRender tests for --strict-all without --strict
- Add clip element test for class-only detection (no id)

* fix: use optional chaining for array access in lintProject tests
TypeScript's strict mode flags array indexing as possibly undefined.
Use optional chaining and fallbacks instead of non-null assertions.

## Summary
- **Lint rules** catch media elements missing `id` (renderer silently skips them), missing `src`, `preload="none"` (blocks renderer), and video nested in timed divs (freezes playback). Upgraded `video_nested_in_timed_element` from warning to error.
- **Compiler** strips `preload="none"` from media during compilation. Runs parallel, cached keyframe interval analysis via ffprobe — warns on sparse keyframes (>2s) that cause seek failures and audio/video desync. Suggested ffmpeg command preserves audio (`-c:a copy`).
- **Pre-render lint** lints `index.html` + all `compositions/*.html` sub-compositions before render via shared `lintProject()` helper. Warns by default; `--strict` blocks on errors, `--strict-all` blocks on errors + warnings.
- **Render orchestrator** logs a hint to retry with `--workers 1` when parallel capture times out on video-heavy compositions.
- **Refactor**: extracted `runFfprobe()` + `parseProbeJson()` helpers to deduplicate ~80 lines of spawn boilerplate across 3 ffprobe functions. Extracted `shouldBlockRender()` so strict flag tests exercise production code. Shared `lintProject()` used by both `lint` and `render` commands.
## Context
Discovered during a real composition build session where:
1. `<audio>` without `id` rendered silently (preview worked fine because runtime queries `[data-start]`, but renderer queries `[id][src]`)
2. `<video>` inside timed `<div>` froze on first frame
3. `preload="none"` caused 45s renderer timeout
4. YouTube clips with sparse keyframes from `yt-dlp --download-sections` caused audio/video desync
5. Parallel workers timed out on video-heavy compositions
## Test plan
- [x] Core: 365/365 tests passing (5 new lint tests)
- [x] Engine: 24/24 tests passing
- [x] CLI: 14/14 tests passing (7 lintProject + 7 shouldBlockRender)
- [x] Lint + format hooks pass
- [ ] Manual: create a composition with `<audio data-start="0" src="test.wav">` (no id) — verify `npx hyperframes lint` catches it
- [ ] Manual: run `npx hyperframes render --strict` with lint errors — verify it blocks
- [ ] Manual: run `npx hyperframes render --strict-all` with lint warnings — verify it blocks
## Summary
- Adds `process.exit(0)` after render completes in the CLI `render` command
- Fixes the process hanging indefinitely after `npx hyperframes render --output video.mp4`
- Root cause: Node.js `fetch()` keep-alive pool (from update checks and telemetry) keeps TCP connections open, preventing the event loop from draining
- Telemetry is preserved — the `exit` handler in `cli.ts` calls `flushSync()` which spawns a detached child process
## Test plan
- [x] Run `npx hyperframes render --output test.mp4` and verify the process exits after completion
- [x] Verify telemetry events are still sent (check PostHog)
- New `updateCheck.ts` utility: cached npm registry check (24h TTL),
sync `getUpdateMeta()` for _meta envelope, `printUpdateNotice()` for
passive stderr banner
- `upgrade --check --json`: machine-readable version check for AI agents
Returns { current, latest, updateAvailable }
- `_meta` envelope on all --json commands (info, lint, benchmark,
compositions): includes version, latestVersion, updateAvailable
- `doctor` shows version check as first row
- Passive update notice on stderr after command completes (skipped in
CI, non-TTY, --json, --quiet)
- Background check fires on startup (non-blocking, populates cache)

- flushSync: use detached spawn + unref() instead of execFileSync,
so process.exit() paths don't block up to 5s on slow networks
- showTelemetryNotice: persist notice flag BEFORE printing/tracking,
so users are never tracked without having seen the disclosure
- Config dir: set mode 0o700 on ~/.hyperframes/ directory (was umask default)
- $ip: null comment: clarify this is belt-and-suspenders with server-side discard
- shouldTrack: update comment — phc_ prefix check is a safety net, not dead code
- env.ts: add comment explaining try/catch fail-safe defaults to production
- init.ts: consistently call trackInitTemplate after scaffoldProject in both paths

- Extract shared isDevMode() to utils/env.ts (was duplicated in dev.ts and client.ts)
- Use ui/colors.ts instead of raw ANSI escapes in telemetry notice (respects NO_COLOR)
- Derive known commands from subCommands object instead of maintaining duplicate set
- Skip telemetry on --help/--version and unknown commands
- Gate incrementCommandCount() behind shouldTrack() (no disk writes in CI)
- Add flushSync() for process.exit() paths (beforeExit doesn't fire on explicit exit)
- Remove dead trackBrowserInstall(success) param (failure path never called it)
- Remove redundant isEnabled/anonymousId caching in client.ts (config.ts cache suffices)

* feat: initial code port from hyperframes-internal
Port all OSS-ready packages from the internal monorepo:
- @hyperframes/core — shared types, HTML generation, GSAP utilities, runtime
- @hyperframes/cli — CLI for creating, previewing, and rendering compositions
- @hyperframes/engine — framework-agnostic rendering engine (BeginFrame + FFmpeg)
- @hyperframes/producer — video rendering pipeline (Puppeteer + FFmpeg)
- @hyperframes/ui-player — browser-based video player component
- @hyperframes/studio — composition editor (React frontend + Hono backend)
Includes regression test suite with Docker-based test harness.
All HeyGen-internal references, deployment infrastructure, and
proprietary assets have been removed. Package names migrated
from @app/* to @hyperframes/*.
