## Summary
- Replaces ~850 lines of inline route handlers in `vite.config.ts` with the shared `createStudioApi(adapter)` module
- Implements `StudioApiAdapter` for the Vite dev server context (SSR-loaded bundler/linter, producer HTTP proxy, Puppeteer thumbnails)
- Bridges Hono `fetch()` to Vite's Connect middleware with streaming support for SSE
Now **both** consumers (CLI + studio) use the same shared API module, ensuring feature parity.
## Test plan
- [x] `pnpm --filter @hyperframes/studio dev` starts correctly
- [x] Home page shows project grid with thumbnails
- [x] Preview plays with correct fonts/animations
- [x] Sub-composition drill-down works
- [x] Lint modal shows findings
- [x] File read/write works in code editor
- [x] Render queue works (requires producer server)

## Summary
Extracts all studio API routes into a shared Hono-based module at `@hyperframes/core/studio-api`.
### Architecture
- **`StudioApiAdapter` interface** — consumers inject host-specific behavior (project resolution, bundling, rendering, thumbnails)
- **Shared route modules**: projects, files, preview, lint, render, thumbnail
- **Shared helpers**: `isSafePath`, `walkDir`, `getMimeType`, `buildSubCompositionHtml`
### What this PR does
- Creates the shared module with all API routes extracted from both `vite.config.ts` and `studioServer.ts`
- Both consumers will be refactored in follow-up commits to mount this module with their own adapter
### What stays in each consumer
- **Vite**: SSR module loading, Puppeteer thumbnails, file watcher + HMR, producer HTTP proxy, multi-project scanning
- **CLI**: in-process `executeRenderJob`, local runtime serving, browser management, SPA static file serving
### Follow-up needed
- [ ] Refactor `packages/studio/vite.config.ts` to use `createStudioApi(adapter)` via `@hono/node-server`'s `getRequestListener`
- [ ] Refactor `packages/cli/src/server/studioServer.ts` to use `createStudioApi(adapter)`
- [ ] Add `./studio-api` export path to `packages/core/package.json`
- [ ] Add `hono` as peer dependency of `@hyperframes/core`
## Test plan
- [ ] Verify shared module compiles without type errors
- [ ] After consumer refactoring: all studio features work identically via both vite dev and CLI embedded servers

## Summary
- Composition HTML files are always wrapped in `<template id="...">` tags
- The linter was checking the raw HTML including the template wrapper, causing false positives:
- `missing-composition-id` on files that have it inside `<template>`
- `missing-dimensions` on files that have `data-width`/`data-height` inside `<template>`
- Fix: strip `<template>` wrapper before linting, matching how the runtime and preview server handle these files
## Test plan
- [x] Added test: `strips <template> wrapper before linting composition files`
- [x] All 345 existing tests pass
- [ ] Verify lint panel no longer shows false positives for composition files

## Changes
Added a new lint rule `gsap_css_transform_conflict` that detects when GSAP animations will silently overwrite CSS transforms.
**`gsap_css_transform_conflict` (error)** — fires when an element has `transform: translateX(-50%)` or `transform: scale()` in CSS and a GSAP `tl.to/from` tween animates `x`, `y`, `xPercent`, `yPercent`, or `scale`. GSAP silently overwrites the full CSS transform, discarding centering tricks like `translateX(-50%)`. Fix hint guides authors to the safe `fromTo` + `xPercent` pattern.
## Root cause
This bug surfaced while building compositions where title reveals were placed off-center because `tl.to("#title", { x: 0 })` stripped the `translateX(-50%)` centering from CSS.
## Test coverage
- [x] `gsap_css_transform_conflict` — `tl.to` with `x` on CSS `translateX` element → error
- [x] `gsap_css_transform_conflict` — `tl.to` with `scale` on CSS `scale()` element → error
- [x] `gsap_css_transform_conflict` — `tl.fromTo` without CSS transform → no finding
Detects querySelector/querySelectorAll calls that use template literal
variables (e.g. `${compId}`) inside script tags. The HTML bundler's
cheerio/css-what parser crashes on these during compilation, causing
silent fallback to raw HTML without runtime injection.
Severity: error (breaks bundling)
Fix: replace template literal with hardcoded composition ID string
## What
Adds 4 new composition templates and fixes structural issues across all templates.
### New templates
- **decision-tree** — animated flowchart with branching paths
- **kinetic-type** — bold kinetic typography promo
- **product-promo** — multi-scene product showcase with SVG assets (3 scenes)
- **nyt-graph** — animated data chart in NYT print editorial style
### Fixes across all templates
- GSAP updated from 3.12.2 → 3.14.2 (all templates, including warm-grain, swiss-grid, vignelli, play-mode)
- New templates restructured with proper root wrapper div, `data-duration`, sub-composition refs with `data-composition-id` / `data-width` / `data-height`
- nyt-chart: replaced `${compId}` template literal variables with hardcoded `"nyt-chart"` string — cheerio's css-what parser crashes on template literals during bundling, causing silent fallback to raw HTML without runtime injection
- nyt-chart: added DOM readiness retry for dynamically created SVG elements
- kinetic-type: removed external S3 audio URL
- All templates: GSAP script loaded in `<head>` before any scripts reference it
## Why
The new templates expand the range of content types available via `hyperframes init`. The fixes ensure all templates work correctly in the studio preview (bundler inlines sub-compositions and injects the runtime).
## Test plan
- [x] All 4 new templates render in studio preview
- [x] nyt-graph chart animates bars, line, and labels on playback
- [x] Existing templates unaffected (GSAP version bump is backwards compatible)
- [x] `hyperframes lint` passes on all templates
- [x] `generators.ts` updated with new template IDs
## 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)
- Init "next steps" now leads with opening in an AI agent as step 1,
followed by dev preview and render as steps 2 and 3
- Interactive init shows a tip about AI agent workflow after scaffolding
- Dev command output hints that compositions can be edited with an
AI agent and changes reload automatically in the studio
The shared CLAUDE.md in scaffolded projects mentioned
hyperframes.heygen.com alongside doc topic names, causing AI agents
to guess incorrect URLs like /compositions instead of using the local
`hyperframes docs` CLI command or the correct /concepts/compositions
path. Now explicitly directs agents to use the CLI for quick reference
and llms.txt for full doc URL discovery.
- Interactive wizard is now the default when running in a TTY terminal
- Non-interactive mode (for CI/agents) uses --non-interactive flag
- Template defaults to "blank" when not specified in non-interactive mode
- --template flag skips the template picker prompt in interactive mode
- Replaces --human-friendly flag with --non-interactive (inverted logic)
npm's sigstore provenance verification requires package.json
repository.url to match the GitHub repo. Without it, publish
fails with E422 "expected to match https://github.com/heygen-com/hyperframes".
- Compute CPU_CORE_COUNT once at module level instead of calling cpus()
multiple times

- Trim oversized JSDoc on defaultWorkerCount

Replace the hardcoded default of 4 workers with a CPU-aware heuristic:
half of available CPU cores, capped at 4. Each worker spawns a separate
Chrome browser process (~256MB RAM each), so the previous default of 4
caused resource contention on smaller machines.
The new defaults:
2-core laptop → 1 worker
4-core laptop → 2 workers
8-core desktop → 4 workers
16-core server → 4 workers (capped)
Also adds --workers auto flag support, improves help text to explain
what workers do, and adds a Workers section to the rendering docs with
guidance on when to increase or decrease parallelism.

## What
Added three new lint rules to the Hyperframe HTML linter to catch common runtime errors and invalid script references.
## Why
These lint rules prevent silent failures and runtime errors that can break Hyperframe compositions:
1. Timeline assignments without initialization guards cause silent failures when `window.__timelines` is undefined
2. Mismatched timeline IDs between `data-composition-id` attributes and `window.__timelines` keys prevent proper auto-nesting
3. Hallucinated script sources referencing non-existent `@hyperframe/` packages result in 404 errors
## How
Implemented three new lint rules with corresponding error codes:
- `timeline_registry_missing_init`: Detects timeline assignments without proper initialization guard using regex pattern matching
- `timeline_id_mismatch`: Cross-references composition IDs from HTML attributes against timeline registry keys to identify mismatches
- `hallucinated_script_src`: Checks script `src` attributes against known bad patterns for non-existent CDN packages
Each rule provides specific error messages and fix hints to guide developers toward correct implementations.
## Test plan
- [x] Unit tests added/updated
- [x] Manual testing performed
- [ ] Documentation updated (if applicable)
Added comprehensive test coverage for all three new lint rules, including both positive and negative test cases to ensure proper detection and avoid false positives.

before writing compositions.
- .claude/skills/{compose-video,captions} — project-level skills for
immediate availability in the current agent session (global skills
require a session restart to discover).
- Updated next-steps output with `hyperframes docs <topic>` and a
link to hyperframes.heygen.com.
- Updated README with "AI Agent Skills" section documenting

## What
Enhanced timeline collection to discover GSAP-animated scene elements and persistent overlays through runtime introspection.
## Why
The existing timeline collection only captured elements with explicit timing attributes (`data-start`, `data-track-index`) or media elements, missing scene elements that are animated purely through GSAP tweens and persistent overlay elements that should appear for the full composition duration.
## How
Added two new discovery mechanisms to `collectRuntimeTimelinePayload`:
1. **GSAP Timeline Introspection**: Walks the master timeline's tweens using `getChildren()` to find animated elements, calculates absolute time ranges by traversing parent timelines, and bubbles child tween ranges up to their nearest scene-level ancestors (direct children of root with IDs).
2. **Persistent Overlay Detection**: Identifies direct children of the root composition that weren't captured by DOM queries or GSAP introspection, treating them as full-duration overlay elements while filtering out non-visual elements (script, style, meta tags) and hidden elements.
Both mechanisms respect existing track assignments and create new tracks when needed to avoid conflicts.
## Test plan
- [x] Unit tests added/updated
- [x] Manual testing performed
- [ ] Documentation updated (if applicable)
Added comprehensive test coverage for:
- GSAP-animated scene element discovery via timeline introspection
- Time range bubbling from child elements to scene ancestors
- Persistent overlay inclusion as full-duration clips
- Proper filtering of non-visual elements (script/style tags)
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.

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.

## 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,
