Adds two lint rules for caption compositions:
- caption_transcript_not_inline: warns when transcript is loaded via
fetch() instead of an inline var TRANSCRIPT array
- caption_transcript_parse_error: warns when the inline TRANSCRIPT
array is not valid JSON (common with unquoted keys + apostrophes)

Documents the inline TRANSCRIPT requirement, JSON-quoted keys, and
CSS class conventions needed for the studio caption editor to detect
and edit captions.

The player needs window.__timelines registered immediately to start
playback. GSAP timelines are mutable so tl.call() entries added
later in the fetch callback still fire when seeked.

- Auto-detect language and switch from .en to multilingual model when needed
- Detect speech onset in WAV to strip hallucinated words before speech begins
- Merge whisper-cpp token fragments: contractions (didn + 't → didn't),

- Interpolate zero-duration word clusters for reliable karaoke timing
- Replace non-null assertions with optional chaining in tests

Audio reactivity applies to any visual element in a composition, not
just captions. Move it to its own skill referenced from compose-video.

## Context
`npx hyperframes render` fails to load assets and produces all-black video. Root causes:
1. CDN scripts (GSAP, Lottie) are left as `<script src="https://...">` in compiled HTML — the headless browser must fetch them over the network, which fails in Docker, CI, and firewalled environments
2. Assets referenced from outside the project directory (e.g. `../shared-assets/hero.png`) 404 because the file server only serves from `projectDir`
3. When GSAP fails to load, the timeline never registers, all `.clip` elements stay `visibility: hidden`, and every frame is black — with no diagnostic output
4. The linter reports `missing_gsap_script` when GSAP is bundled inline (no `<script src>` tag), which blocks users from working around the CDN issue
## What changed
### 1\. CDN script inlining (`htmlCompiler.ts`)
`compileForRender` now downloads all external `<script src="https://...">` tags at compile time and inlines their content into the HTML. Rendering no longer needs network access.
| Before | After |
| --- | --- |
| `<script src="https://cdn.jsdelivr.net/npm/gsap@3.12.5/dist/gsap.min.js"></script>` stays in HTML, browser must fetch at runtime | Script downloaded during compilation, embedded as `<script>/* inlined: https://... */\n...code...</script>` |
| Docker/CI render → `net::ERR_NAME_NOT_RESOLVED` → black video | Render works fully offline |
| No feedback when CDN fails | `[Compiler] WARNING: Failed to download CDN script: ... Consider bundling it locally` |
### 2\. External asset copying (`htmlCompiler.ts`, `renderOrchestrator.ts`)
After compilation, the HTML is scanned for `src`, `href`, and CSS `url()` references that resolve outside `projectDir`. These files are copied into the compiled output directory so the file server can serve them.
| Before | After |
| --- | --- |
| `background-image: url(../shared-assets/hero.png)` → 404 (file server can't serve outside `projectDir`) | Asset detected, copied to compiled dir, path rewritten → serves correctly |
| `<img src="../shared-assets/logo.png">` → 404 | Same fix — works for all `src`/`href` attributes and CSS `url()` |
### 3\. Black video diagnostics (`renderOrchestrator.ts`)
When composition duration is 0 (which would produce a black video), the error now probes the browser for diagnostics instead of a generic message.
| Before | After |
| --- | --- |
| `Invalid composition duration: 0. Check that GSAP timelines are registered.` | `Composition duration is 0 — this would produce a black video.\n\nDiagnostics:\n - GSAP is not loaded — CDN script may have failed to download. Bundle GSAP locally...\n - Browser: [Browser:PAGEERROR] gsap is not defined` |
| Asset 404s during page load silently logged | `[Render] Asset load failure: ...` + `[WARN] Browser encountered network failures during page load` |
### 4\. Linter: recognize inline GSAP (`core/lint/rules/gsap.ts`)
The `missing_gsap_script` rule now recognizes GSAP bundled inline — matching the producer's inlining comment (`/* inlined: ...gsap... */`), GSAP library internals (`_gsScope`, `GreenSock`), and large inline scripts (>5KB) referencing gsap.
| Before | After |
| --- | --- |
| User inlines GSAP → linter errors with `missing_gsap_script` | Inline GSAP detected, no false error |
| Producer inlines CDN → linter errors on the compiled HTML | Producer's `/* inlined: ... */` comment recognized |
## Test plan
- [x] `pnpm build` passes
- [x] Core tests pass (410/410, +2 new)
- [x] **Reproduced baseline failures on** **`main`**: CDN scripts not inlined, external assets 404, no diagnostics
- [x] **Verified fixes**: CDN script inlined, external assets copied and served, diagnostics printed
- [x] Render with working CDN → `[Compiler] Inlined CDN script: ...` → render succeeds
- [x] Render with broken CDN → `[Compiler] WARNING: Failed to download CDN script` + browser errors surfaced
- [x] Render with assets outside project dir → `[Compiler] Found 1 asset(s) outside project directory` → assets served correctly
- [x] Linter with inline GSAP → no `missing_gsap_script` false positive
* feat(cli): improve --help with grouped commands and per-command examples
Replaces citty's flat COMMANDS list with kubectl-style grouped categories
and adds examples to every subcommand. Root help now groups 14 commands
into 5 categories (Getting Started, Project, Tooling, AI & Integrations,
Settings). Per-command --help now appends a formatted Examples section
with practical usage patterns.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(cli): use shared colors, lazy-load help, fix description drift
- Replace hand-rolled ANSI helpers with existing ui/colors.ts (fixes
non-conformant NO_COLOR handling)
- Add cyan and gray to shared color module
- Lazy-load help.ts via dynamic import to avoid allocating help data
on non-help invocations
- Fix description drift: benchmark and transcribe descriptions now
match their command meta.description
- Unify tuple order: ROOT_EXAMPLES now uses [comment, command] to
match COMMAND_EXAMPLES
- Remove redundant comment restating type annotation
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): resolve typecheck error in showUsage generic signature
The lazy-load wrapper needs to cast CommandDef<T> to CommandDef when
forwarding to the help module, since TypeScript's generic variance
makes the direct assignment incompatible.

## Summary
- rewrite CSS `url(...)` asset paths from sub-compositions before styles are hoisted into bundled/master preview output
- rewrite standalone sub-composition preview HTML so `src`/`href` paths keep resolving correctly under the preview root `<base>`
- add regression tests for bundled CSS asset rewriting and standalone sub-composition preview rewriting
## Root cause
Standalone composition previews reused the project `<head>` with a preview-root `<base href="/api/projects/:id/preview/">`, but the sub-composition body still contained `../...` asset references. Those escaped the preview route and 404ed. Separately, bundled preview already rewrote `<img src="../...">` paths but left hoisted CSS asset references like `@font-face src: url("../font.woff2")` untouched.
## Validation
- `pnpm --filter @hyperframes/core exec vitest run src/compiler/htmlBundler.test.ts src/studio-api/helpers/subComposition.test.ts`
- `pnpm --filter @hyperframes/core exec tsc --noEmit`
- `pnpm --filter @hyperframes/producer exec tsc --noEmit` *(blocked by pre-existing `packages/producer/src/services/deterministicFonts.ts` importing missing generated file `./fontData.generated.js` in the worktree install)*
- browser verification with `agent-browser` against the local preview server using `/Users/miguel07code/dev/test-hyperframes/heygen-promo`
## Browser proof
Verified the fixed preview routes in-browser after seeking to visible frames:
- standalone composition preview
- bundled master preview
## What
Move the id-less media fix into the shared timing compiler so producer can resolve durations for sub-composition videos before inlining, then carry the merged result through engine parsing, regression coverage, and the regression Docker image used in CI.
This PR now does five concrete things:
- assigns stable ids to id-less media in core `compileTimingAttrs()` so unresolved duration injection can target them
- keeps the engine-side `parseVideoElements()` support for `video[src]` plus the newer `data-duration` / natural-duration fallback from `main`
- makes producer prefer sub-composition media metadata over the later inlined-document parse when the same media id appears in both places
- makes `sub-composition-video` a runnable regression test by fixing its metadata and checking in the missing `output/compiled.html` snapshot
- removes the stale `pnpm-workspace.yaml` copy step from `Dockerfile.test`, so regression CI builds the Bun-based test image from the current workspace layout
## Why
- media without an explicit `id` could not participate in unresolved-duration resolution early enough
- producer could lose the resolved sub-composition timing by overwriting it with the later inlined parse
- the regression fixture intended to cover this case was not actually running in CI because its `meta.json` was incomplete and the required compiled snapshot was missing
- the regression image definition still expected a deleted `pnpm-workspace.yaml`, so GitHub Actions failed before the test shard could start
Putting the id-generation step in core makes the behavior reusable instead of relying on producer-only HTML patching.
## How
### Shared compiler
- core `compileTimingAttrs()` now auto-assigns stable ids to id-less `video` / `audio` tags
- those generated ids are returned in `unresolved`, so `injectDurations()` can add `data-duration` and `data-end` to the same media element later in the pipeline
- added core tests that cover auto-id assignment and duration injection for generated ids
### Producer
- when producer combines `subVideos` / `subAudios` with the media re-parsed from the final inlined HTML, it now lets the sub-composition metadata win
- this preserves the resolved/clamped timing already computed for nested media instead of overwriting it with the later parse
- `sub-composition-video` now has valid regression metadata and a checked-in `output/compiled.html` snapshot so CI actually executes it
### Engine
- resolved the merge conflict in `videoFrameExtractor` by keeping the broader `video[src]` parsing from this branch and the `data-duration` / natural-duration fallback that landed on `main`
- added a focused engine unit test for videos without ids
### CI image
- `Dockerfile.test` now copies only `package.json` and `bun.lock` at the workspace root before `bun install --frozen-lockfile`
- this matches the current monorepo layout and removes the obsolete pnpm-era dependency on `pnpm-workspace.yaml`
## Test plan
- [x] `bun run --filter @hyperframes/core test`
- [x] `bun run --filter @hyperframes/engine test`
- [x] `bun run --filter @hyperframes/producer test --update --sequential sub-composition-video`
- [x] `bun run --filter @hyperframes/producer test --sequential sub-composition-video`
- [x] Browser check with `agent-browser` against the compiled fixture page (`http://127.0.0.1:8123/compiled.html`)
- [x] Clean tracked-only Docker build of `Dockerfile.test` with the PR version of the file applied
## Notes
- Latest regression workflow is green on `main`, but before this PR the `sub-composition-video` fixture was being skipped by the harness rather than exercised end to end.
- The CI Docker fix was validated from a tracked-only export to avoid local untracked worktree artifacts affecting the result.
## What
Added progress reporting to the skills installation process by converting synchronous operations to asynchronous ones and implementing progress callbacks.
## Why
The skills installation process can take a significant amount of time, especially when cloning repositories or running npm operations. Users need feedback about what's happening during the installation to understand progress and know the system hasn't frozen.
## How
- Converted `execFileSync` calls to a new `execFileAsync` function using promises
- Made all installation functions (`runSkillsAdd`, `gitClone`, `fetchRepo`, `fallbackInstall`) asynchronous
- Added an optional `onProgress` callback parameter to `installAllSkills` that accepts progress messages
- Integrated progress reporting in the `init` command by passing spinner message updates to the progress callback
- Added progress messages for key installation steps like "Installing {source} skills..." and "Cloning skill repositories..."
- Added "giget" to the external dependencies list in the build configuration
## Test plan
- [ ] Unit tests added/updated
- [ ] Manual testing performed
- [ ] Documentation updated (if applicable)
* feat(skills): add audio visualizer effect with extraction script
Adds reactive audio visualization patterns for HyperFrames:
Script: extract-audio-data.py pre-extracts per-frame RMS amplitude and
frequency band data via ffmpeg. Uses a 4096-sample FFT window for clean
frequency resolution and per-band normalization across the full track
so treble activity is visible alongside louder bass.
Patterns: spectrum bars, mirrored waveform, pulsing circle, circular
visualizer, background glow — all Canvas 2D driven from the GSAP
timeline via tl.call() at each frame.
Includes smoothing helper, band count guide, band ordering rules
(horizontal: low-left high-right), and combining patterns section.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(skills): replace prescriptive examples with data model + motion principles
Removes five hardcoded draw functions that would get copy-pasted verbatim.
Replaces with:
- Clear data model docs (what rms and bands mean, how to index)
- Rendering approach setup for Canvas 2D, WebGL/Three.js, and DOM
- Motion principles (smoothing, value mapping, what makes it feel good)
- Spatial mapping conventions (low-left/high-right, etc)
The LLM invents the visualization; the skill teaches the data contract
and motion constraints.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(skills): off-by-one in band slicing, add data loading, fix trigger
- Fix exclusive slice end: high_bin clamped to n_bins (not n_bins-1)
so the last FFT bin in each band is included
- Add data loading section to skill doc (inline and fetch patterns)
- Fix example JSON to show frame 0 at time 0.0
- Update description to trigger when audio is analyzed and music detected
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor(skills): require numpy, fix bugs, clean up skill doc
Script rewrite:
- numpy is now required (pure-Python DFT was unusable for real files)
- Use np.frombuffer instead of struct.unpack (~10x less memory)
- Precompute Hann window and band edges (were recalculated every frame)
- Extract SAMPLE_RATE as module-level constant
- Clamp band bins to prevent max() on empty slice
- Validate --fps and --bands inputs
Skill doc fixes:
- Fix fetch loading example (was null ref on sync for-loop)
- Remove redundant Canvas 2D section (was duplicate of Step 3)
- Fix opening line (said "Canvas 2D" but doc covers 3 approaches)
- Fix undefined W/H in example

## Summary
- Add `/api/projects/:id/upload` endpoint for multipart file uploads with automatic dedup naming
- Wire `onImportFiles` from Assets tab "Import media" button through to the upload API
- Add global drag-drop overlay — drop media files **anywhere** in the studio, not just the Assets panel
- Files that already exist get `(2)`, `(3)` suffixes instead of overwriting
- Support uploading into subdirectories via `?dir=` param — dropping on a folder imports there
- Make folders draggable in the file tree + support drop-to-root
- Add `bodyLimit` middleware for early rejection of oversized payloads
- Surface skipped/failed uploads via toast notification instead of console-only
Addresses feedback: _"Wish I could upload/drag-drop assets directly in the Studio (music, images, video) like a CapCut media panel"_
## Test plan
- [x] Open studio, drag an image/video/audio file onto any part of the UI
- [x] Verify the drop overlay appears with "Drop files to import" message
- [x] Drop the file — verify it appears in the Assets tab and file tree
- [x] Drop a file with the same name — verify it gets a `(2)` suffix
- [x] Click "Import media" button in Assets tab — verify file picker works
- [x] Import multiple files at once via drag-drop
- [x] Drop a file onto a nested folder in the file tree — verify it lands in that folder
- [x] Drag a folder in the file tree and drop it on another folder or root — verify it moves
- [x] Drop a file >500MB — verify toast notification appears
- [x] Verify drag overlay doesn't get stuck when dragging over nested UI elements
## Summary
- **Fixes**: `<img src="../icon.svg">` and similar `../` relative asset references in sub-compositions resolve to 404 after inlining into the root document
- **Unifies**: Both `hyperframes preview` (core bundler) and `hyperframes render` (producer) now use the same shared logic — no duplication
## Root cause
When inlining a sub-composition at `compositions/scene.html` into root `index.html`, a relative path like `../icon.svg` is correct from `compositions/` (it points to project root) but after inlining, `../` escapes the project directory.
## Fix
Extracts path rewriting into a shared `rewriteSubCompPaths.ts` utility in `@hyperframes/core`, used by both the bundler and the producer. **Only rewrites paths starting with** **`../`** — plain relative paths like `assets/foo.svg` are already correct from the root perspective and must not be rewritten (this was the regression cause in `overlay-montage-prod`: sub-composition asset refs like `assets/notch.svg` were incorrectly being rewritten to `compositions/assets/notch.svg`).
## Regression fix
The earlier version of this fix (now in history) rewrote ALL relative paths including `assets/foo.svg`, breaking the `overlay-montage-prod` regression test. This PR fixes that by scoping rewrites to `../`\-prefixed paths only.
## Test plan
- [x] `../icon.svg` in sub-composition renders correctly in both preview and render
- [x] `assets/foo.svg` (no `../`) in sub-composition still resolves correctly — not rewritten
- [x] `overlay-montage-prod` regression test passes
- [x] All other regression shards pass
* feat(cli): add remote template fetching via giget
* fix: update remote.ts to use templates/ instead of examples/
* fix(cli): validate template ID against manifest before downloading
Fails fast with available template list instead of downloading
an empty directory for nonexistent templates.
* refactor(cli): simplify to single --template flag with dynamic validation
- Remove --example flag (--template handles bundled + remote)
- Remove static ALL_TEMPLATE_IDS list (validates against GitHub manifest)
- No CLI release needed to add new templates — just add to templates/ and templates.json
- scaffoldProject auto-detects bundled vs remote
* chore: update lockfiles for giget dependency
* fix(cli): remove undefined isAudioOnly reference
## Summary
- **Fixes**: External `<script src="...">` tags in sub-compositions (e.g. GSAP TextPlugin, ScrollTrigger) were silently discarded during `hyperframes render`, causing `ReferenceError` at runtime
- **Root cause**: The producer's `inlineSubCompositions` skipped external scripts with `if (src) continue` but then removed them via the blanket `querySelectorAll("style, script").forEach(remove)` — they were never hoisted to the parent document
- **Fix**: Mirror the core bundler's (`htmlBundler.ts`) approach — collect external script `src` URLs, deduplicate against existing scripts in the parent, and inject as `<script>` tags before inline composition scripts
## How to reproduce
1. Create a sub-composition that uses GSAP TextPlugin:
```html
<script src="https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/TextPlugin.min.js"></script>
<script>
gsap.registerPlugin(TextPlugin);
tl.to("#text", { text: { value: "Hello" }, duration: 1 });
</script>
```
1. Run `hyperframes render`
2. Browser console shows: `[Compiler] Composition script failed scene-hook ReferenceError: TextPlugin is not defined`
## Test plan
- [x] Verify `hyperframes render` on a project using TextPlugin in a sub-composition no longer errors
- [x] Verify external scripts are deduped (same CDN URL in 2 sub-compositions → only 1 `<script>` tag)
- [x] Verify external scripts already in `index.html` are not duplicated
- [x] Verify script order: external CDN scripts load before inline composition scripts
* refactor(cli): move templates to examples/ for remote fetching
* refactor(cli): rename examples/ to templates/ for clarity
Follows Remix/Vite convention — these are init scaffolds, not general examples.
* feat(docs): add template gallery page with visual previews
* fix(docs): remove invalid MDX heading anchors
* chore: retrigger CI
* feat(docs): merge gallery into templates page with hover-to-play video previews
- Consolidated gallery.mdx and templates.mdx into single templates.mdx
- Moved templates page to Getting Started section
- Added MP4 video previews rendered by hyperframes (hover to play)
- Custom JS for hover-to-play behavior (Mintlify strips JSX event handlers)
- 2-column grid for landscape, 3-column for portrait
- Remotion-style cards with gradient overlay labels
* fix(docs): update broken links after templates page move
* ci(regression): remove scripts/ from regression trigger paths
scripts/ contains dev utilities (lint, versioning, preview generation)
that don't affect the rendering engine.
## Summary
- **Streamline init from 7 steps to 3**: name → template → auto-opens studio preview
- **Remove** interactive "Got a video or audio file?" prompt (`--video`/`--audio` flags still work)
- **Remove** "What do you want to do?" post-scaffold menu (auto-launches preview)
- **Fast startup**: `--version` exits in ~10ms (lazy-load telemetry + update checker)
- **Brand teal**: CLI accent color is now `#3CE6AC` instead of generic cyan
### Before
```
name → overwrite? → media file? → [drag file] → transcribe? → pick template (9) → what next?
```
### After
```
name → pick template → auto-opens studio
```
## Test plan
- [x] `hyperframes init my-project` — should prompt name + template, then auto-open preview
- [x] `hyperframes --version` — should print version instantly (~10ms)
- [x] `hyperframes init --video path.mp4 my-project` — video flag still works
- [x] `hyperframes init --template blank my-project` — template flag still works
- [x] Verify teal accent color in terminal output
* feat(skills): add gsap-effects skill with typewriter pattern
Distills typewriter text animation into a reusable reference:
basic typewriter, blinking cursor, word rotation, appending words,
and a characters-per-second timing guide. Uses GSAP TextPlugin.
Also references the new skill from compose-video.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(skills): emphasize cursor must always blink when idle and sit flush
Two key rules added to the typewriter skill:
1. Cursor must blink in every idle state (after typing, after clearing,
during hold pauses) — a solid idle cursor looks broken.
2. No whitespace between text and cursor elements in HTML — any gap
between the last character and the caret looks wrong.
Also adds cursor-hide state for multi-line handoffs and updates word
rotation example to include cursor state management.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(skills): backspace must delete from end, not front
TextPlugin's text:{value:""} removes characters from the front,
which looks wrong. Added a backspace helper that steps through
substrings from right to left using tl.call(). Updated word
rotation example to use it.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(skills): handoffs must blink before typing, use margin for spacing
Two lessons from testing:
1. Cursor handoffs need a blink pause — going hide→solid directly
skips the idle state. Pattern: hide→blink→pause→solid→type→blink.
2. Use margin-left on a wrapper span for spacing between static and
dynamic text. Flex gap spaces the cursor away, trailing spaces
collapse.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(skills): enforce single visible cursor as a hard rule
Only one cursor may be visible at a time. Multiple cursors on
screen looks broken. Every other cursor must be cursor-hide.
Promoted to rule #1 in the cursor section.

## What
Add a script that uses `@hyperframes/producer` to render PNG thumbnails of each built-in template. Output goes to `docs/images/templates/`.
## Why
User feedback: "I would have loved more visual examples of what's actually possible. I had to scaffold every template just to see what they look like." This is the foundation for a visual template gallery in the docs.
## How
- New `scripts/generate-template-previews.ts` uses the producer's `createFileServer` + `createCaptureSession` + `captureFrame` APIs — hyperframes renders its own templates
- Patches out `__VIDEO_SRC__` placeholders (same logic as `init.ts`) so templates render without a video file
- Captures a frame at t=2s for each template (skips `blank` — it's just empty scaffolding)
- Handles varying dimensions (vignelli is 1080x1920 portrait)
- Adds `pnpm generate:previews` npm script
## Test plan
- [x] `pnpm generate:previews` generates 8 PNGs in `docs/images/templates/`
- [x] Each PNG is visually correct (verified by viewing)
- [x] `--only <template>` flag works for single template generation
## Summary
- **API**: POST (create), DELETE (delete), PATCH (rename/move), POST duplicate endpoints with null-byte sanitization
- **FileTree**: right-click context menu with New File, New Folder, Rename, Duplicate, Delete
- **Drag-and-drop**: move files between folders with visual feedback and subtree guard
- **Inline editing**: rename/create inputs with filename validation
- **Header actions**: quick New File / New Folder buttons in the FILES header
Stacks on top of `feat/studio-code-quality`.
## Test plan
- [x] Right-click file → Rename, Delete, Duplicate all work
- [x] Right-click folder → New File, New Folder, Delete work
- [x] Drag file from one folder to another
- [x] Create file with invalid name (`../foo`, `a/b`) → rejected client-side
- [x] Delete currently-edited file → editor clears
- [x] Studio build succeeds

* feat(skills): add hyperframes-cli skill for CLI workflow guidance
Adds a new skill that teaches AI agents how to use the HyperFrames CLI
(init, lint, dev, render, doctor). Previously, agents had no way to
discover the CLI — the compose-video skill only covered HTML authoring.
This led to agents searching for binaries, finding the monorepo, and
running bun run studio manually instead of using npx hyperframes dev.
Also registers the skill in init.ts so new projects get it bundled
alongside hyperframes-compose and hyperframes-captions.

* refactor(cli): rename dev command to preview
The command starts a preview server — "preview" describes what users

name, all CLI references, docs, skills, and template CLAUDE.md.
22 files updated across CLI source, docs, skills, and templates.

- Generalized for all text elements (captions, titles, etc.), not just captions
- Unit tests (mocked pretext) + browser integration test (real Chromium canvas)
- Updated captions skill docs with usage, exit guarantee, and self-lint patterns

## Summary
The timeline is now hidden by default. A toggle button appears in both the header (alongside panel toggles) and the player controls bar. Both sync the same state and turn teal when the timeline is visible.
## Changes
- **`timelineVisible` state** in `App.tsx`, defaults to `false`
- **Header toggle**: icon button between sidebar toggle and Renders button
- **Player controls toggle**: icon button at the right end of the controls bar
- **NLELayout**: `timelineVisible` and `onToggleTimeline` props gate the timeline + resize divider
- **Player controls stay visible**: moved from inside the timeline section to inside the preview area, so hiding the timeline doesn't hide play/seek/timecode
## Behavior
| State | Preview | Player controls | Timeline |
|---|---|---|---|
| Timeline hidden (default) | Full height | ✅ Visible | Hidden |
| Timeline visible | Shorter | ✅ Visible | Shown with resize handle |
Both toggle buttons show identical teal active state (`#3CE6AC/10` bg + `#3CE6AC/30` border).

* feat(cli,core): add standalone transcribe command, transcript normalization, and caption lint rules
- Add `hyperframes transcribe` command for transcribing audio/video and importing
existing transcripts (SRT, VTT, OpenAI Whisper API JSON, whisper.cpp JSON)
- Add transcript format normalizer (normalize.ts) with auto-detection and
conversion to standard [{text, start, end}] word arrays
- Upgrade default whisper model from base.en to small.en for better accuracy
- Add --model and --language flags to both `transcribe` and `init` commands
- Extract shared patchCaptionHtml() to eliminate duplication between init.ts
and transcribe.ts (init.ts reduced by ~55 lines)
- Add 3 caption lint rules: caption_exit_missing_hard_kill,
caption_text_overflow_risk, caption_container_relative_position
- Update captions skill with model guide, format docs, music guidance,
text overflow prevention, caption exit guarantee pattern
- Expand captions skill trigger to cover lyrics, karaoke, lyric videos

* fix(cli): fix blank template lint issues
- blank/index.html: remove data-start from video (was nested in timed parent),
add class="clip" for initial hidden state
- blank/captions.html: add max-width + overflow:hidden to prevent text clipping,
add tl.set hard kill after exit tween to prevent stuck captions

## Summary
Removes the `ProjectPicker` home screen entirely. The studio now boots directly into the editor by auto-selecting the first available project from `/api/projects`.
## Changes
- **Auto-select on load**: When no `#project/` hash is present, fetches the project list and navigates to the first one
- **Type narrowing**: Added `if (resolving || !projectId)` early return so TypeScript narrows `projectId` to `string` for all downstream props
- **Removed**: `ProjectPicker`, `ProjectCard`, `ExpandedPreviewIframe` components (~280 lines), `handleSelectProject` callback, `ProjectEntry` interface
## Why
The CLI studio always has exactly one project. The home page was an extra click with no value.

## Summary
- Adds `loadInlineTemplateCompositions` to the runtime to handle compositions defined inline via `<template id="X-template">` paired with empty host elements that have `data-composition-id="X"` but no `data-composition-src`
- Updates the HTML bundler to inline template content into matching hosts during compilation
- Users can now define sub-compositions inline instead of requiring separate files in `compositions/`
### Before
```html
<!-- This showed nothing — the template was inert and the host was empty -->
<template id="logo-reveal-template">
<div data-composition-id="logo-reveal" data-width="1920" data-height="1080">
<style>...</style>
<script>/* animation */</script>
</div>
</template>
<div data-composition-id="logo-reveal" data-start="0" data-duration="10"
data-width="1920" data-height="1080"></div>
```
### After
The runtime detects the matching `<template>` and injects its content into the host element — styles hoisted to `<head>`, scripts executed, dimensions copied. Works in both preview and render.
## Test plan
- [x] 9 new unit tests for `loadInlineTemplateCompositions` (basic mount, no-op cases, style/script injection, dimensions)
- [x] 3 new unit tests for bundler inline template handling
- [x] All 384 existing tests pass
## 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
## Summary
Adds `docs/guides/testing-local-changes.mdx` — a contributor guide explaining how to test unreleased CLI changes against real projects outside the monorepo.
**Covers:**
- `pnpm link --global` (recommended — makes `hyperframes` in `$PATH` point at your local build)
- `node` alias (no PATH changes)
- `npm pack` (test the exact artifact that would be published)
- Troubleshooting (`which hyperframes`, port conflicts, stale builds)
- Table of test scenarios for each bug category
Also registers the page in `docs/docs.json` so it appears in the Guides nav.
* 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.

The --tag flag was optional, which led to v0.1.11 and v0.1.12 being
bumped without tags — skipping npm publish entirely. Invert the default:
always commit + tag, with --no-tag as the escape hatch.
