The blank template was a bare `<div>` fragment without `<!DOCTYPE>`,
`<head>`, or `<body>`. This caused:
- Blank preview (bundler/runtime can't initialize from a fragment)
- "Failed to run lint" (parsing errors on the malformed document)
All other templates (swiss-grid, vignelli, warm-grain, play-mode) are
proper HTML documents — blank was the only outlier.
Also improves lint error reporting to show the actual error message
instead of the generic "Failed to run lint."

The SIGINT handlers that were meant to do graceful cleanup (close server,
remove symlinks) override Node's default exit behavior. If the cleanup
hangs (e.g. server.close() blocked by open connections), the process is
stuck and Ctrl+C does nothing.
Fix: don't intercept SIGINT at all. Node's default behavior exits the
process immediately on Ctrl+C. The OS reclaims the port and file handles.
Use process.on("exit") for best-effort symlink cleanup instead.
Also fixes running the CLI via `tsx` in dev mode — __CLI_VERSION__ is a
tsup build-time define that crashes at runtime without a fallback.

## Summary
- Fix silent failure when `hyperframes dev` port (default 3002) is already in use (e.g., by Cursor IDE)
- Replace TOCTOU-prone `isPortAvailable()` probe with `serveWithPortFallback()` that binds the real server directly
- Auto-increment to next available port with a visible yellow warning, or show a clear error when all ports (range of 10) are exhausted
## What changed
The old approach used a throwaway `net.createServer()` to test port availability, closed it, then opened the real Hono server — a classic TOCTOU race. The fallback also silently returned the original port when all 10 were taken.
Now we use `createAdaptorServer()` (creates the Hono HTTP server without binding) and manually call `.listen(port)`, catching `EADDRINUSE` to try the next port. This eliminates the race entirely.
**Before:** `hyperframes dev` says "Studio running at http://localhost:3002" even when port 3002 belongs to another process.
**After:**
- Port available: works as before
- Port taken: `Port 3002 is in use, using 3003 instead` (yellow warning)
- All ports taken: `Ports 3002–3011 are all in use. Use --port to specify a different port.` (error + exit)
## Testing
- Verified TypeScript compiles cleanly (`tsc --noEmit`)
- All pre-commit hooks (lint, format, commitlint) pass
- Manual test: run another server on 3002, then `hyperframes dev` → confirms auto-increment message appears
🤖 Generated with [Claude Code](https://claude.com/claude-code)
The embedded dev server (hyperframes dev) silently reported success even
when the requested port was already in use (e.g., by Cursor IDE on 3002).
This happened because the old isPortAvailable() probe had a TOCTOU race
and findAvailablePort() silently fell back to the original port on exhaustion.
Replace with serveWithPortFallback() that binds the real Hono server
directly via createAdaptorServer + manual listen(), retrying on EADDRINUSE.
Shows a yellow warning when auto-incrementing and a clear error when all
ports are exhausted.

- Use static import for copyFileSync (was unnecessary dynamic import)
- Shallow-copy config before mutating forceScreenshot (prevents
caller-provided config from being permanently modified)
- Consolidate isWebm/isWebmRender/outputFormat into single early
declaration in renderOrchestrator
- Fix debug output extension for WebM (was hardcoded .mp4)
- Log unexpected audio extraction errors instead of silently swallowing

## Changes
- Add optional `entryFile` parameter to render API endpoints (`/v1/render` and `/v1/render-stream`)
- Enable rendering individual sub-compositions by extracting them from index.html context when the entry file is a `<template>` wrapper
- Change base64 audio/video linting from detecting "fabricated" media to prohibiting all inline base64 media
- Add manifest path resolution for bundled producer deployments
## API Changes
- `RenderConfig` — new optional `entryFile` field for specifying HTML file to render
- `server.ts` — parses `entryFile` from request body, validates file exists in project directory
- `executeRenderJob` — uses `entryFile` instead of hardcoded `"index.html"`
## Template Extraction
- `extractStandaloneEntryFromIndex` — extracts sub-composition hosts from index.html and creates standalone render context
- Handles `<template>` entry files by finding matching `data-composition-src` in index.html and isolating that host
- Resets `data-start` to 0 for standalone rendering
## Linting Updates
- Change rule #3.7 from detecting "fabricated" base64 media to prohibiting all inline base64 audio/video
- Lower detection threshold from 100+ to 20+ base64 characters
- All base64 media now triggers error severity with clearer messaging about file size bloat
## Usage
```json
POST /v1/render-stream
{ "projectDir": "/path/to/project", "entryFile": "compositions/intro.html" }
```
Omit `entryFile` for default behavior (renders `index.html`).
- Engine: document getEncoderPreset() for MP4/WebM, VP9 alpha flags,
Opus audio in mux step
- Producer: document format field in RenderConfig, WebM usage example,

The VP9 alpha encoding works correctly — verified by overlaying on a
green background with explicit VP9 decoder. FFmpeg's default decoder
doesn't expose VP9 alpha through ffprobe, but browsers and VP9-aware

- Force screenshot capture mode for WebM (beginFrame doesn't support
alpha channel in chrome-headless-shell)
- Set Emulation.setDefaultBackgroundColorOverride once during session
creation (matching experiment-framework's approach)
- Fix acquireBrowser to pass executable path in screenshot mode on
Linux (was setting undefined, causing puppeteer-core to fail)
- Add Page.captureScreenshot params: fromSurface, captureBeyondViewport,
optimizeForSpeed (matching experiment-framework)
- Fix regression harness extractMonoPcm16 for videos without audio
- Add getEncoderPreset unit tests
- Add webm-transparency regression test with golden baseline

- New regression test `webm-transparency`: minimal transparent composition
rendered to WebM, validates VP9 codec and visual quality at 100
checkpoints against golden baseline
- Extend regression harness: `renderConfig.format` field ("mp4" | "webm"),
format-aware output paths and snapshot filenames
- Fix `extractMonoPcm16` to gracefully handle videos without audio
streams (WebM without audio was throwing instead of returning empty)
- Unit tests for `getEncoderPreset()`: VP9/yuva420p for WebM,
h264/yuv420p for MP4, preset mapping, quality preservation
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Support rendering compositions with transparent backgrounds via
`--format webm`. VP9+alpha is the standard format for overlayable
video (captions, lower thirds, overlays).
Changes by layer:
- CLI: `--format mp4|webm` flag on render command
- Producer: threads format through RenderConfig, switches to PNG
capture and VP9 encoding when webm
- Engine: getEncoderPreset() returns VP9 config with yuva420p;
transparent page background via CDP when capturing PNG;
mux uses Opus audio for WebM; VP9 flags from production:
-row-mt 1, -auto-alt-ref 0, alpha_mode=1 metadata
- Frame capture: Emulation.setDefaultBackgroundColorOverride a=0

## What
When a composition has an empty GSAP timeline (no animations), `window.__hf.duration` was always 0, causing `hyperframes render` to time out after 45 seconds waiting for `duration > 0`.
## Why
The HF bridge script reads duration from `window.__player.getDuration()`, which returns the GSAP timeline duration. An empty timeline has duration 0. The render engine waits for `window.__hf.duration > 0` to confirm the runtime is ready — so compositions with no animations would always deadlock.
This hits the `--template blank` scaffold immediately: it generates an empty GSAP timeline and relies solely on `data-duration="10"` for composition timing.
## How
One-line change to the bridge script: when `getDuration()` returns 0, fall back to reading `data-duration` from the root `[data-composition-id]` element. This is the same value the static compiler already extracted — so we get a correct duration without any extra browser round-trips.
```js
get duration() {
var d = p.getDuration();
return d > 0 ? d : getDeclaredDuration(); // reads data-duration from root element
}
```
## Test plan
- [x] `hyperframes init my-video --template blank && hyperframes render my-video` completes successfully
- [x] Output: `output.mp4` — 10s, 1920×1080, 30fps ✓
- [x] Compositions with actual GSAP animations unaffected (fallback only triggers when timeline duration is 0)
- [x] Build passes, lint/format clean
- Document the three dev server modes (embedded/local studio/monorepo)
- Add --port flag to dev command
- Document _meta envelope on all --json commands
- Document upgrade --check --json for agent consumption
- Document passive update notices and HYPERFRAMES_NO_UPDATE_CHECK
- Update doctor output example with Version check row
- Fix README default port from 3000 to 3002
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- 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)

- version.ts: replace hardcoded "0.1.0" with __CLI_VERSION__ injected by
tsup at build time from package.json — fixes version mismatch where
`hyperframes --version` reported 0.1.0 while package was 0.1.4
- tsup.config.ts: add define.__CLI_VERSION__ using package.json version
- render.ts: renderDocker error handler showed "Try --docker" even when
already using --docker — changed to "Check Docker is running: docker info"
- dev.ts: add missing --port arg to embedded mode; findAvailablePort now
starts from the user-supplied port instead of hardcoded 3002

When installed via npx, `hyperframes dev` now starts a standalone
Hono HTTP server that serves the pre-built studio SPA and implements
the project API (file listing, read/write, preview bundling,
sub-composition rendering, runtime serving, SSE file watching).
Three modes are auto-detected:
1. Monorepo dev (running from .ts source) → spawn Vite (existing)
2. Local @hyperframes/studio installed → spawn Vite via package (new)
3. Default → embedded Hono server (new, zero extra deps needed)
Also patches the studio SPA to use EventSource SSE fallback when
Vite HMR is unavailable (production/embedded builds).

## Summary
- copy data-start from the host sub-composition node to the inlined inner composition root
- preserve the correct runtime offset lookup for nested compositions after producer compilation
- avoid nested GSAP timelines snapping to their end state when the host starts later than t=0
Reverting the package rename — Vance needs @hyperframes/cli for local

The CLI is published to npm as unscoped `hyperframes` but the

The previous approach called loadHyperframeRuntimeSource() to regenerate
the runtime IIFE, but its output lacked the trailing newline present in

The CLI's ensureBrowser() finds Chrome via env var, cached download,
or system paths (including /Applications/Google Chrome.app on macOS).
But the result was discarded — the engine's acquireBrowser() only
checked the puppeteer cache for chrome-headless-shell, passing
undefined executablePath on macOS without headless-shell installed.
Bridge the two by setting PRODUCER_HEADLESS_SHELL_PATH from the CLI's
resolved browser path before creating the render job, so the engine's
resolveConfig() picks it up.

The hyperframeRuntimeLoader uses import.meta.url to resolve
hyperframe.manifest.json as a sibling file. When bundled into the CLI
via tsup, import.meta.url points to dist/cli.js, so the sibling lookup
checks dist/hyperframe.manifest.json — which wasn't being shipped.
Copy the manifest and the canonical-named runtime IIFE into dist/ during
the build-runtime step so the loader's sibling-path resolution works in
published npm packages.

## Summary
- Anti-default: don't draw real-world objects with SVG paths — they look crude. Geometric shapes and abstract forms only.
- Anti-default: every element needs clear space — overlapping text is always ugly.
- Replaced zoom-in monoculture in choreography — now offers 6 ambient motion options instead of always zooming.
- Added scene pacing: build/breathe/resolve phases.
Follow-up to the house style PR (#59, merged). These fixes came from visual review of 20+ eval compositions.
## Test plan
- [ ] Generate a composition with a sparse prompt and verify no SVG illustrations of real objects
- [ ] Verify elements don't overlap in generated compositions
- [ ] Verify ambient motion varies (not always zoom-in)

The CLI bundle uses tsup to inline @hyperframes/producer, but the
deterministicFonts module used require.resolve('@fontsource/*/package.json')
at runtime to find woff2 files on disk. When installed via npx, these
@fontsource packages don't exist, causing "Cannot find module" errors.
Replace runtime filesystem lookups with a build-time generator that reads
all @fontsource woff2 files and produces a TypeScript module with base64
data URIs. The generator runs before both producer and CLI builds, making
the bundle fully self-contained with zero @fontsource runtime dependencies.

## Summary
- rewrite workspace protocol dependencies to publish-safe semver ranges before the npm publish workflow runs
- keep workspace protocol references in source manifests for normal monorepo development
- ensure the published `@hyperframes/producer` manifest no longer ships unresolved `workspace:` deps
## Why
The internal repo hit a Docker build failure because the published `@hyperframes/producer` metadata still contained `workspace:^` dependencies for `@hyperframes/core` and `@hyperframes/engine`. `npm install` cannot resolve those outside the monorepo, so the published package itself was the root cause.
## Validation
- `bun install --frozen-lockfile`
- `bun run build:producer`
- `bun run prepare:publish-manifests`
- `npm pack --workspace packages/core`
- `npm pack --workspace packages/engine`
- `npm pack --workspace packages/producer`
- installed the three tarballs together in a clean temp project with `npm install --ignore-scripts`
- extracted the producer tarball and verified its `package.json` contains `^0.1.3` for `@hyperframes/core` and `@hyperframes/engine`, not `workspace:^`
## Release v0.1.3
Bumps all packages to v0.1.3.
### Changes since v0.1.2
- fix(producer): resolve manifest from sibling dist/ directory
- fix(producer): add margin reset when wrapping HTML fragments
- fix(producer): exclude test files from tsc build
- feat(cli): add opt-out anonymous telemetry via PostHog
- feat: add HyperFrames skills for AI coding tools
- fix(cli): resolve npx hyperframes from inside monorepo
- fix(ci): publish workflow fixes (remove provenance, idempotent steps, remove prepublishOnly)
After merging, the release tag is created automatically, which triggers npm publish.

* feat(skill): add house style guide with motion defaults, palettes, and anti-defaults
When no visual-style.md is provided, compose-video now follows house-style.md
for professional output quality. Includes:
- Motion: easing variety, timing, entrance patterns, choreography
- Sizing: text scale contrast, element fill, travel distance
- Visual depth: gradient/shadow/texture guidance
- Typography: weight contrast, tracking, case
- Anti-defaults: table of generic AI patterns to avoid
- 72 curated color palettes across 9 categories
- Content interpretation: generate real content, not prompt text
Eval-validated across 5 iterations with 50+ test compositions.

* feat(skill): add container anti-default and typography guidance
- Anti-default: discourage card/container patterns in favor of content

- Typography section: weight contrast, deliberate case, tracking, one
typeface at two weights
- Visual depth: softened to avoid templating (content-appropriate, not
every-composition-the-same)

* feat(cli): add whisper transcription to init flow
New modules:
- whisper/manager.ts: download/cache whisper.cpp binary + model
(~/.cache/hyperframes/whisper/)
- whisper/transcribe.ts: extract audio, run whisper, save transcript.json
Init flow changes:
- "Got a video or audio file?" now accepts audio-only files (mp3, wav, m4a)
- "Generate captions from audio?" prompt after file selection
- Transcription produces transcript.json in project root
- Graceful fallback if whisper/ffmpeg unavailable
Supports: macOS ARM64/x86, Linux x86_64. Downloads whisper.cpp v1.7.3
from GitHub releases and ggml-base.en model from Hugging Face.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): use brew/system whisper instead of downloading binaries
whisper.cpp doesn't ship pre-built macOS/Linux CLI binaries.
Use brew install whisper-cpp on macOS (auto-installs if brew available),
system PATH lookup otherwise. Model still downloaded from Hugging Face.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): simplify whisper install — detect or instruct, don't build
Remove build-from-source complexity. If whisper-cpp is found on PATH,
use it. If not, show install instructions instead of blocking:
"To generate captions, install whisper-cpp: brew install whisper-cpp"
The transcription prompt only appears when whisper is available.
When it's not, the user sees the install command and can re-run init.

* feat(cli): auto-install whisper via brew or build from source
ensureWhisper() now tries 4 strategies in order:
1. System PATH (whisper-cli or whisper already installed)
2. Homebrew (macOS: brew install whisper-cpp)
3. Build from source (git clone + cmake, ~30-60s)
4. Show install instructions as last resort
Init flow always asks "Generate captions?" — whisper is installed
automatically in the background if needed. No user intervention
required on macOS with Xcode CLI tools or any system with git+cmake.

* fix(cli): add muted and playsinline to all template video elements

* fix(cli): flat asset structure + separate audio tracks in templates
Assets: video, images, fonts all go at project root (not assets/ or
fonts/ subdirectories). The studio preview can't resolve relative
paths from subdirectories due to the /preview URL suffix.
Audio: added <audio> elements alongside muted <video> in all 4
templates so the video's audio plays back. The framework requires
muted video + separate audio element.
Removed assets/ and fonts/ directory creation from scaffoldProject.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(studio): inject base tag for asset resolution in preview
The preview iframe serves bundled HTML from /api/projects/:id/preview
but relative asset paths (video.mp4, font.woff2) resolve to the wrong
URL without a <base> tag. Now injects <base href="/api/projects/:id/preview/">
so relative paths route through the static asset handler.
Also adds proper MIME types for video, audio, image, and font files
served from the preview asset route.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(studio): serve HyperFrames runtime in dev mode
The preview runtime script had an empty src — the framework never
loaded, so video playback and clip lifecycle didn't work.
Now auto-detects packages/cli/dist/hyperframe-runtime.js and serves
it at /api/runtime.js. No env var needed in dev mode.

* fix(cli): filter whisper special tokens from transcript
Use --output-json instead of --output-json-full to avoid special
tokens like [_TT_485] and [BLANK_AUDIO]. Also filter remaining
bracket tokens when building the word array for captions.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): use --output-json-full for word-level timestamps
--output-json only produces segment-level timing (no tokens).
--output-json-full is required for word-level timestamps that
the captions template needs. Special tokens are filtered out
by the patchTranscript function.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(cli): patch template durations to match uploaded video
Templates now use __VIDEO_DURATION__ placeholder that gets replaced
with the actual probed video duration. All data-duration values on
the root composition, video, audio, and caption clips are updated.
Without a video, defaults to 10 seconds.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): merge punctuation tokens with preceding word

appeared as standalone words in captions, sometimes in the wrong
group. Now merged with the preceding word during transcript

* fix(cli): match both TRANSCRIPT and script variable names in templates
Three templates use `const TRANSCRIPT = [...]` while warm-grain uses
`const script = [...]`. The patchTranscript function now matches both.

* feat(cli): add blank template option, smart defaults for video vs audio
- Blank template: minimal scaffolding (root composition, video, audio,
GSAP timeline) with __VIDEO_SRC__ and __VIDEO_DURATION__ placeholders
- Template defaults: video uploads default to "blank" (user brings
their own content), audio-only defaults to "warm-grain" (motion
graphics template since there's no video to show)
- Audio-only projects now tracked with isAudioOnly flag

* fix(cli): address whisper review feedback
- Clean stale builds: if BUILD_DIR exists but no binary, nuke and retry
- Build failures clean up BUILD_DIR so next attempt starts fresh
- patchTranscript regex scoped within <script> blocks to prevent
matching across block boundaries
- Removed hardcoded model size hint (~148MB)
