Miguel Ángel 246a1911b1 fix(studio): auto-reconnect when preview server is not running (#802)
* fix(studio): auto-reconnect when preview server is not running

When the preview server is not reachable (tab reload after server died,
or opening the URL before running npm run dev), the Studio was silently
swallowing the fetch error and rendering an infinite pulsing dot with no
recovery path. Users had no idea what happened.

Instead of showing an error and asking the user to act, the Studio now
polls /api/projects every 2 seconds and automatically transitions into
the full editor the moment the server becomes available — no manual
reload required.

Also fixes how agents are instructed about the dev server: CLAUDE.md and
AGENTS.md listed `npm run dev` as a one-liner comment identical to other
commands, giving no indication it blocks until stopped. Agents (including
Claude Code) were running it in foreground, timing out after ~2 minutes,
and silently killing the server. Added an explicit note that it must be
started as a background process.

* fix(studio): auto-reconnect when preview server is not running

Two issues combined to produce the "reloading the tab kills the whole"
experience for users running with an AI agent:

1. Agents silently killed the server — CLAUDE.md/AGENTS.md listed
   npm run dev with no indication it blocks. Agents ran it in foreground,
   the Bash tool timed out, and the process died. Added an explicit
   run_in_background instruction.

2. Studio had no recovery path — fetch errors were swallowed, leaving
   a permanent pulsing dot with no way out. Now the Studio polls every
   2s and auto-transitions the moment the server responds.

Also fixes the bookmark-reload case: the hash path previously bailed out
before pinging the server, so a dead server + saved URL produced a blank
editor instead of the waiting state. The server is now always contacted
first, regardless of whether a hash project ID is present.

Timer cleanup (cancelled flag + clearTimeout) prevents setState on
unmounted components under StrictMode dev re-mounts.

Extracted into useServerConnection hook to keep App.tsx under the 500
LOC limit.

Miguel Ángel 0d7d38849c fix(studio): align preview fonts with render (#799)
## What

Align Studio preview font handling with final render, and harden the transform hook against failures.

## Why

Preview and render use different font handling. This bug changes text width and makes text layout look different between preview and final render.

## How

- Add a `transformPreviewHtml` hook in `StudioApiAdapter` that adapters can implement to post-process preview HTML before Studio augments it
- Use it in both the Vite adapter and the CLI studio server to inject the same deterministic `@font-face` rules that render uses
- Wrap the hook in a try/catch so a failing transform (e.g. network error during Google Fonts fetch) degrades gracefully — the preview still loads with the original HTML

## Edge cases covered

| Path | Covered |
|------|---------|
| Bundled HTML (adapter returns string) | ✓ |
| Bundle returns null → reads index.html from disk | ✓ |
| Bundle throws → catch-block fallback reads index.html | ✓ |
| Sub-composition preview | ✓ |
| Transform hook throws → graceful fallback to original HTML | ✓ |

## Test plan

- [x] Unit tests added for all five paths above
- [x] Manual testing performed

Closes #797

James 067bc722e3 fix(deps): align @types/node + esbuild + tsx across workspace
The Windows install failures (`ENOENT: failed copying files from cache to
destination for package @types/node` / `esbuild`) are caused by bun creating
workspace-scoped nested installs under
`node_modules/@hyperframes/<pkg>/node_modules/...`. Those nested paths only
exist because each workspace package pinned a different `@types/node` /
`esbuild` major:

- root: `@types/node ^25.0.10`, core: `^24.10.13`, cli/engine/producer: `^22`
- core/cli: `esbuild ^0.25.x`, producer: `^0.27.2`

Each major-version gap forces bun to install a workspace-scoped copy in a
deep `node_modules/@hyperframes/<pkg>/node_modules/<dep>/node_modules/...`
tree that bun can't reliably materialize on Windows GHA runners. Aligning
versions lets bun dedup to a single root-hoisted install per dep, and the
nested workspace block disappears from `bun.lock` entirely.

## Alignment

- `@types/node` → `^25.0.10` across root, core, cli, engine, producer
- `esbuild` → `^0.25.12` across cli, core, producer
- `tsx` → `^4.21.0` across producer (matches root + core)

## Source-level v25 compat (already in this PR)

@types/node v25 declares `File` as an interface (not a class) and exposes a
conditional global where `FormData.entries()` narrows to `[string, string]`
when an `onmessage` global is in scope. `packages/core/src/studio-api/routes/files.ts`'s
`value instanceof File` check was relying on the v24 class declaration —
already cast the iterator to `Iterable<[string, FileLike | string]>` in the
prior commit.

Two more v25 source fixes here:
- `packages/cli/src/commands/init.ts`
- `packages/cli/src/whisper/normalize.ts`

`Dirent.path` was removed in @types/node v25 (deprecated alias for
`parentPath` since Node 20.12). Drop the `?? e.path` fallback.

## Verification

Both install layouts now build clean end-to-end:

- `bun install` (isolated, default): full build green, 853 core tests pass,
  typecheck green across all 7 packages
- `bun install --linker=hoisted` (Windows CI): same result
- `bun.lock` no longer contains any `@hyperframes/<pkg>/<dep>` nested
  workspace entries — 70+ lines of nested install blocks gone

Miguel Ángel 91bdffffe6 fix(ci): scope LOC check to studio, split useTimelinePlayer + hyperframes-player under 500 LOC (#750)
* refactor: split useTimelinePlayer.ts and hyperframes-player.ts into focused modules (<500 LOC each)

* fix(ci): scope 500 LOC check to packages/studio, add allowlist for grandfathered files

* feat(cli): Linux ARM64 support — auto-install Chromium on DGX Spark / GB10 / Jetson

Chrome Headless Shell has no Linux ARM64 binary. On arm64 Linux:
- Detects the platform automatically
- Tries to auto-install system Chromium via apt-get (works on Ubuntu/Debian ARM)
- Falls back to clear manual instructions with exact commands
- 'hyperframes browser ensure' guides through the setup interactively
- After setup, all render commands work without any flags

* fix(ci): disable Windows Defender real-time monitoring to prevent EPERM builds

Path exclusions are insufficient — Defender re-scans new files created
during bun install before the exclusion takes effect. Disable real-time
monitoring for the entire job duration instead (standard CI practice).

* refactor(studio): split all files >500 LOC + extract useToast, delete allowlist

All 11 large files split into focused modules under 500 LOC.
App.tsx extracted toast logic into useToast hook (493 LOC now).
.filesize-allowlist deleted — no longer needed.

* fix: remove unused imports from split files, extract useToast from App.tsx

App.tsx: 504 → 493 lines (toast logic extracted to useToast hook)
timelineDOM.ts: remove unused imports from re-export pattern
MotionPanel.tsx: remove unused clampStudioCustomEasePoints import
studioMotionOps.ts: remove unused StudioGsapMotionDirection import

* fix(ci): use Set-MpPreference to fully disable Windows Defender (both jobs)

* fix(producer): use node --experimental-strip-types instead of tsx for build:fonts

Eliminates the tsx binary dependency that Windows Defender locks during
bun install, causing EPERM errors. Node 22.6+ strips TypeScript types
natively with no external binary.

* chore: remove .filesize-allowlist — App.tsx is now 493 lines (<500)

* fix(ci): disable Windows Defender before checkout to prevent all EPERM races

* fix(producer): skip build:fonts if fontData.generated.ts already exists

The generated file is tracked in git, so CI doesn't need to regenerate
it. This avoids @fontsource/inter node_modules access on Windows which
triggers EPERM from Defender scanning during bun install.

* feat(studio): add persistent undo redo (#537)

Studio manual editing and timeline editing mutate project files directly, but those edits had no reliable undo/redo path. Before releasing manual editing, users need a way to recover from visual property changes, source-editor saves, timeline moves/resizes/deletes, and timeline asset drops.

The history also needs to survive a page refresh. A refresh should not erase the only way back from a bad manual edit.

- Adds a persistent per-project edit-history model for file snapshots.
- Stores undo/redo stacks in IndexedDB so history survives Studio refreshes.
- Records source editor saves, manual DOM edits, and timeline mutations.
- Adds toolbar undo/redo buttons with standard keyboard shortcuts: `Cmd/Ctrl+Z`, `Cmd/Ctrl+Shift+Z`, and `Ctrl+Y`.
- Validates current file hashes before applying undo/redo so external file changes do not silently overwrite newer content.
- Keeps history available in memory if IndexedDB persistence fails during a session.
- Adds focused unit coverage for the pure history model, storage adapter, controller/hook behavior, and project-file save helper.

Studio previously treated every editor mutation as an immediate file write. Manual DOM editing, timeline updates, and source-editor saves each had separate write paths, so there was no common transaction boundary where Studio could capture the file contents before and after an edit.

Undo/redo needed to sit above those write paths as a file-level transaction system: capture changed files before saving, write the new contents, persist the history entry by project, then apply undo/redo only when the current file content still matches the expected snapshot.

- Clicked Undo and verified the project file returned to `left: 220px`; clicked Redo and verified the inline `left: 260px` returned.
- Used `agent-browser` to drag the `side-card` timeline clip, refreshed Studio, then verified Undo restored the previous timeline attributes and Redo reapplied the timeline move.
- Recorded the tested undo/redo flow with `agent-browser`: `qa-artifacts/studio-undo-redo-2026-04-28/studio-undo-redo-flow.webm`.

* fix: align Studio capture with preview (#595)

Studio frame capture could fail for projects mounted outside the repo when the project id came from an encoded hash route. A project like `Notion Showcase` loaded as `#project/Notion%20Showcase`, but the capture URL encoded that already-encoded value again, producing `/api/projects/Notion%2520Showcase/...` and a 404.

While validating the fix by seeking through the preview, capture also diverged from the visible player for nested compositions because the thumbnail route sought raw timelines instead of the same player seek path used by Studio preview.

- Decodes project ids when reading Studio `#project/...` routes and centralizes project hash/API path construction.
- Keeps API URLs encoded exactly once, including project names with spaces, literal `%`, reserved characters, and unicode.
- Updates Studio thumbnail capture to prefer `window.__player.seek(t)` and only fall back to raw timeline seeking for standalone pages.
- Preserves explicit `t=0` thumbnail requests instead of falling back to `0.5` seconds.
- Adds preview-regression CI coverage for Studio routing, frame capture URL construction, thumbnail seeking, and core thumbnail seek parsing.

Studio treated the hash route segment as the canonical project id even when the browser had already percent-encoded it. `buildFrameCaptureUrl` then encoded that string again, so a decoded project directory name and the capture API path no longer matched.

The preview/capture mismatch was a separate seek-path issue: the visible Studio preview seeks through the HyperFrames player, which maps global time into nested composition time. The capture route bypassed that layer and paused all registered timelines at the same global time.

The zero-second capture case came from parsing `t` with a truthiness fallback, so `parseFloat("0") || 0.5` became `0.5`.

Pre-commit also reran lint, format, and typecheck successfully for the committed files.

Using `agent-browser`, I mounted `/Users/miguel07code/Downloads/Notion Showcase` into Studio's project data and opened:

```text
http://127.0.0.1:5197/#project/Notion%20Showcase
```

Before the fix, Capture requested `/api/projects/Notion%2520Showcase/thumbnail/index.html?...` and Studio showed `Capture failed`.

After the fix, I sought the preview to `0s`, `2s`, `10s`, and `18s`, captured each frame, and compared the visible preview crop against the capture output. The capture URLs all used `Notion%20Showcase`, not `Notion%2520Showcase`, and no failure toast appeared.

Mean pixel diffs for preview vs capture were:

- `0s`: `0.0`
- `2s`: `0.8641`
- `10s`: `0.3496`
- `18s`: `0.2309`

The small non-zero diffs are raster/antialias-level differences after resizing the capture to the preview crop dimensions.

- Browser screenshots, comparison sheets, network logs, and the `agent-browser` recording are local-only under `qa-artifacts/capture-button/` and are not committed.
- The local Notion Showcase project mount is an ignored symlink under `packages/studio/data/projects/` and is not committed.
- Thumbnail cache versions were bumped so stale captures generated with the old seek behavior are not reused.

Fixes and improvements based on power-user testing feedback:

1. Fix stale selection after style edits — handleDomStyleCommit now
   calls refreshDomEditSelectionFromPreview after persisting, matching
   every other commit handler. Without this, the PropertyPanel showed
   frozen computedStyles after color/radius/shadow edits, making it
   look like editing "didn't work." Also adds error handling around
   the persist call.

2. Add rotation field to the Design panel Layout section — reads the
   current rotation angle from the manual edit manifest and commits
   via the existing handleDomRotationCommit handler.

3. Enable motion panel by default — STUDIO_MOTION_PANEL_ENABLED now
   defaults to true so the Motion tab is discoverable without env vars.

4. Color controls only when element has color — fill color section now
   only shows when the element has an explicit non-transparent
   background-color. Text color shows only when the element has a
   color style. Prevents showing color pickers on elements where
   color edits have no visible effect.

5. Exclude canvas from selection — added "canvas" to
   DOM_LAYER_IGNORED_TAGS so canvas elements are not selectable in the
   preview or listed in the layer panel.

6. Multi-selection feedback — shows "N elements selected" with
   guidance instead of the generic empty state when multiple elements
   are selected.

* fix(studio): prevent browser launch timeout from crashing dev server

The shared Puppeteer browser pool in getSharedBrowser() could throw a
30s TimeoutError during launch. This error propagated as an uncaught
rejection and killed the vite process, even though generateThumbnail
had its own try/catch — the browser launch promise rejected outside
that scope. Now getSharedBrowser itself catches launch failures and
returns null, so thumbnails degrade gracefully instead of crashing.

Motion panel stays opt-in via env var per product direction. Only

* fix(studio): prevent read-only property crash in manual edit wrappers

The seek/play/applyAfter wrapper functions in manualEdits.ts crashed
with "Cannot set property X which has only a getter" when the player
or timeline objects define seek/play as getter-only properties. This
prevented ALL manual edits (position, rotation, size) from persisting
to disk — the error thrown during applyCurrentStudioManualEditsToPreview
aborted the save queue.

Wrapped all three property assignments in try/catch so wrapping
gracefully degrades when the target object is non-configurable.

Verified: position edit (X=42px) now persists to
.hyperframes/studio-manual-edits.json and survives page refresh.

* fix: alpha preview e2e fixes — exports, init templates, EPIPE crash

Three bugs found via automated e2e testing of the v0.6.0-alpha preview:

1. core: add missing package.json export specifiers for
   studio-api/manual-edits-render-script and
   studio-api/studio-motion-render-script — the alpha.3 npm publish
   failed because the studio build could not resolve these sub-paths.

2. cli: fix init --example creating empty projects — tsup leaves empty
   template directories in dist/ during the build, causing
   existsSync(templateDir) to return true and skip the remote fetch
   fallback. Now checks for index.html inside the dir instead.

3. engine: fix unhandled EPIPE crash in streaming encoder — ffmpeg
   stdin/stdout had no error handlers, so a write after the ffmpeg
   process exits throws an uncaught error that crashes the process.

Verified with 8 consecutive e2e iterations (424 test runs, 0 flaky).

* fix(studio): thumbnail crash, feature defaults, multi-select UX, fps selector

Power-user audit fixes for the alpha studio:

- vite.config.ts: wrap thumbnail generation in try/catch so Puppeteer
  TimeoutError doesn't crash the entire vite dev server as an uncaught
  rejection. Close the page on error to prevent browser session leaks.

- manualEditingAvailability.ts: enable motion panel and manual canvas
  drag editing by default (were both false, undiscoverable without
  knowing the env vars).

- PropertyPanel.tsx: show "N elements selected" feedback when multiple
  elements are selected instead of the generic "Select an element"
  empty state.

- RenderQueue.tsx + App.tsx: add FPS selector (24/30/60) to the render
  export bar instead of hardcoding 30fps. Pass the user's choice
  through to startRender.

* chore: release v0.6.0-alpha.4

* fix(runtime): update clock duration when root timeline is late-bound

Compositions with external sub-compositions (like apple-presentation
with 7 slides) load child compositions via fetch(). The root GSAP
timeline is only bound after all external compositions finish loading,
but the TransportClock duration was only set during initial setup.

When bindRootTimelineIfAvailable runs after the external compositions
load, it captures the root timeline but never updates the clock.
player.getDuration() continues returning 0, so the player's probe
interval never fires the 'ready' event, and the Studio shows "Loading
composition" indefinitely.

Now bindRootTimelineIfAvailable updates clock.setDuration when the
root timeline is late-bound. Guarded with try/catch for the early call
site where clock is not yet initialized (temporal dead zone).

* fix(studio): block element selection while composition is loading

Prevent users from selecting elements in the preview while the
composition is still loading (showing "Loading composition" overlay).
Selection and hover highlighting are suppressed until the player fires
the ready event.

Also reverts motion panel and manual drag editing defaults to false —
these were accidentally set to true during the PR #693 merge.

* fix(runtime): remove per-tick timeline.pause() that causes audio stutter

The seekRuntimeTimeline helper added timeline.pause() before every
totalTime() seek. During transport-driven playback, this runs 60 times
per second, causing GSAP to cascade pause events to media elements on
every frame. The result: audio plays/stops/plays/stops in a stutter
pattern.

The captured root timeline is already paused once in player.play() —
the TransportClock drives it via totalTime(t) which keeps it paused.
The extra per-tick pause() was redundant for the root timeline but
actively harmful for media sync.

Fix: restore the original inline seek for the captured timeline
(totalTime without pause), keep seekRuntimeTimeline with pause() only
for standalone child timelines where explicit pause control is needed.

Also fixes rebase artifact: missing PropertyPanel props in App.tsx.

* chore: release v0.6.0-alpha.8

* fix(runtime): comprehensive audio stutter fix

Three changes that together caused audio play/stop/play/stop stutter
during transport-driven playback:

1. seekRuntimeTimeline called timeline.pause() before every totalTime()
   seek, 60x per second. GSAP cascades pause to media elements on every
   frame. Fix: restore original inline seek for the captured timeline
   (totalTime without pause). The timeline is already paused once in
   player.play(). seekRuntimeTimeline with pause() remains only for
   standalone child timelines.

2. player.play() removed the !tl guard, allowing play without a
   captured timeline. But getSafeTimelineDurationSeconds(null) returns
   0, so the clock has no duration → immediately reaches end → stops →
   restarts. Fix: when no timeline provides duration, fall back to the
   root composition element's data-duration attribute.

3. Audio source attachment added networkState guard that could cause
   the clock to flicker between audio-source and monotonic timing
   on transient media states. Fix: keep !rawEl.error guard (prevents
   errored audio from freezing the clock) but drop the networkState
   check.

* fix(runtime): skip drift corrections on playing video elements

Seeking a playing video resets the browser's decoder pipeline, causing
a ~150ms freeze while it re-buffers. During that freeze the monotonic
clock advances, drift grows, and strict sync fires another seek —
creating a perpetual stutter loop (176 seek events / 8s observed on
the apple-presentation composition).

Skip strict and force drift corrections for playing video elements;
only hard sync (>0.5s catastrophic drift) warrants the decoder-reset
cost. Audio elements are unaffected and retain the full correction
tiers.

Also propagate the asset-loading overlay state to the timeline so
controls are disabled during "Preparing preview assets", matching the
existing behavior for the initial composition loading overlay.

Move all window-level keyboard shortcuts from 4 separate files into
one `handleAppKeyDown` listener in App.tsx:

- Shift+T: toggle timeline (was App.tsx, separate useMountEffect)
- Cmd/Ctrl+Z: undo (was App.tsx, separate useEffect)
- Cmd/Ctrl+Shift+Z: redo (was App.tsx, separate useEffect)
- Cmd/Ctrl+1: sidebar Compositions tab (was LeftSidebar.tsx)
- Cmd/Ctrl+2: sidebar Assets tab (was LeftSidebar.tsx)
- Delete/Backspace: remove selected element (was Timeline.tsx)

LeftSidebar exposes a ref handle for tab switching. Timeline watches
selectedElement becoming null to clean up popover/range UI state.
History hotkey kept as named function for iframe forwarding.

Playback shortcuts (Space, J/K/L, arrows) and caption nudge remain
in their component hooks — tightly coupled to component state.

* fix(studio): sidebar tab overflow + hot-reload double-refresh

1. Sidebar tabs: use equal 1fr columns, shorter "Comps" label, truncate
   on overflow, tighter padding. Fixes tabs clipping outside the rounded
   pill at narrow sidebar widths.

2. Hot reload: set domEditSaveTimestampRef before every save-then-refresh
   path (source editor, timeline move/resize/delete, asset drop). The
   file-change watcher already checks this timestamp and suppresses
   echoed events — but source editor saves and timeline operations
   weren't setting it, causing a double refreshKey increment that could
   leave the player in a non-playable state.

* fix(studio): delete key removes preview-selected elements

The consolidated keyboard handler only checked selectedElementId
(timeline clips). When a user selected a child element in the
preview via the inspector, selectedElementId was null because
the element didn't correspond to a top-level timeline clip, so
Delete/Backspace did nothing.

Add handleDomEditElementDelete that removes the element referenced
by the current domEditSelection via the remove-element mutation
API. The Delete key handler now falls through from timeline
selection to DOM edit selection.

* fix(studio): remove unused deleteInFlightRef from Timeline

Leftover from moving Delete handling to the consolidated
keyboard handler in App.tsx. Also suppress pre-existing
exhaustive-deps warning on the intentional every-render
selection-change watcher.

* fix(studio): forward all keyboard shortcuts to preview iframe

The consolidated handleAppKeyDown was only added to the parent
window. When focus was inside the preview iframe (after clicking
an element), keydown events didn't reach the parent, so Delete
and other shortcuts didn't fire.

Replace the per-function iframe forwarding (handleTimelineToggleHotkey
only) with the full app-level handler via a ref-stable wrapper.
All app shortcuts (Delete, Undo/Redo, Shift+T, Cmd+1/2) now work
from within the preview iframe.

* fix(core): search inside <template> content when removing elements

linkedom's document.querySelectorAll does not traverse <template>
content. Elements in template-based compositions (like .title-word,
.bullet-text) were invisible to the removal logic, so delete
returned changed: false and the element survived the reload.

Fall back to template.querySelectorAll when the document-level
query returns no matches. Uses template.querySelectorAll directly
(not template.content.querySelectorAll) because removing from
the content DocumentFragment doesn't update the serialized output.

* fix(studio): suppress loading overlay on hot-reload

Only show the composition loading overlay on the first iframe load.
Hot-reloads (source editor save, timeline edits, element delete)
no longer flash the full-screen loading state.

* fix(studio): reorder design panel, fix stroke height, rename Blending

- Move Text section to the top of the panel (before Layout)
- Remove Selection Colors section
- Rename "Blending" to "Transparency"
- Fix stroke Width/Style height mismatch by making SelectField
  use inline label layout matching MetricField

* fix(studio): prevent panel scroll when wheel-adjusting metric inputs

React registers onWheel passively, so preventDefault had no effect
on the parent scroll container. Replace with a native wheel listener
(passive: false) that blocks both default scroll and propagation.

* chore: release v0.6.0-alpha.10

* chore: release v0.6.0-alpha.11

* fix(studio): clean next alpha inspector artifacts

* chore: release v0.6.0-alpha.12

* fix(studio,player,core): eliminate double audio and manifest polling loop (#722)

Three bugs that compound in Studio preview:

1. **Double audio on pause/resume**: syncRuntimeMedia played audio through
   the HTML <audio> element while WebAudioTransport simultaneously played
   the same source through AudioBufferSourceNode. Fixed by passing
   webAudio.isActive() as outputMuted so HTML elements stay muted when
   Web Audio owns playback. Also removed the priorMuted restore in
   stopAll() which raced with the next play cycle.

2. **Manifest polling loop**: applyStudioManualEditsToPreview and
   applyStudioMotionToPreview unconditionally fetched from disk on every
   call, even without forceFromDisk. The runtime posts state messages
   every frame via postMessage, triggering React re-renders that re-invoked
   these functions ~60x/second. Fixed by returning early when no disk read
   is requested, and using refs instead of callbacks in useEffect deps.

3. **Parent proxy double-play**: the player web component created parent-frame
   audio proxies even when the runtime bridge was available, causing two
   audio sources on autoplay-blocked promotion. Fixed by skipping proxy
   creation when _hasRuntimeBridge returns true, and synchronously muting
   iframe media on promotion to close the async race window.

Also fixes pre-existing ResolutionPreset type missing square variants.

* fix(studio): improve font picker and text property controls (#736)

- Line height and letter-spacing: convert from free-text to select with presets
- Font style: remove oblique (browser falls back to italic), keep normal/italic
- Font weight: detect available weights via document.fonts.check(), add labels
- Font source: local fonts matching Google catalog tagged as Google
- Font list: balanced per-source caps prevent any source from being cut off
- Sort order: Google fonts rank before Local so curated fonts appear first

* fix(studio): inspector visibility, undo/redo blinking, and preview caching

Inspector picks invisible elements when an ancestor has GSAP-set opacity: 0
because CSS opacity is not inherited — getComputedStyle on the child still
returns 1. Walk the ancestor chain in the picker, domEditing, and overlay
visibility checks to catch this.

Also:
- Containers with all-invisible children are no longer selectable
- Selection/hover overlay hides during playback and while loading
- Undo/redo no longer double-refreshes (echo suppression for all file writes)
- Undo/redo reloads iframe in-place instead of recreating the Player,
  preserving shader transition cache
- Preview routes return ETag + Cache-Control headers; composition HTML uses
  project signature for conditional 304, binary assets use mtime+size
- Loading overlay deferred 400ms so cached loads never flash it

* fix(studio): remove timeline inspector buttons, enable manual dragging

Remove the eye icon (inspector) and image icon (thumbnail toggle) from timeline
clips. The timeline layer inspector feature and all supporting code is removed.

Enable manual dragging in the preview by default. Add scrub-to-drag on X/Y/W/H
fields in the design panel. Hide the Radius section when the element has no
visible background. Fix pre-existing ResolutionPreset type for square presets.

* chore: release v0.6.0-alpha.13

* fix(studio): add rotation field, inline element drag, fix manifest load regression (#743)

- Add rotation (R) field to geometry row (X, Y, W, H, R) in property panel.
  Goes through manifest via handleDomRotationCommit, resettable with Reset Edits.
- Auto-promote display:inline elements to inline-block when dragged so
  translate works on inline spans.
- Fix regression from polling fix: iframe load now passes readFromDiskFirst
  to load manifest from disk, so Reset Edits finds existing entries.

* refactor(studio): decompose App.tsx monolith (4297 → 567 lines) (#741)

* refactor(studio): decompose App.tsx from 4297 to 567 lines

Break the monolithic StudioApp component into focused modules:

Hooks (12 new):
- usePanelLayout: resizable/collapsible panel state
- useFileManager: file tree, CRUD, uploads, derived lists
- useManifestPersistence: manual edit + motion manifest save queue
- useTimelineEditing: clip move/resize/delete/drop handlers
- useDomEditSession: DOM selection, style/text commits, preview interaction
- useAppHotkeys: keyboard shortcuts, undo/redo, iframe hotkey sync
- useCaptionDetection: auto-detect caption compositions
- useRenderClipContent: timeline clip thumbnail rendering
- useConsoleErrorCapture: preview iframe console error capture
- useFrameCapture: frame capture download flow
- useLintModal: lint execution and modal state
- useCompositionDimensions: stage-size message listener

Components (6 new):
- AskAgentModal: agent prompt modal
- StudioHeader: toolbar with undo/redo, capture, inspector toggle
- StudioLeftSidebar: file tree + code editor (handles collapsed state)
- StudioPreviewArea: NLELayout + overlays + caption timeline
- StudioRightPanel: Design/Motion/Renders tab panel
- TimelineToolbar: zoom controls + timeline toggle

Utilities (4 new):
- studioHelpers: types, path helpers, DOM utilities
- studioPreviewHelpers: preview pointer/player interaction
- domEditHelpers: selection group algebra
- studioFontHelpers: font injection + @font-face management

Also removes dead timeline layer inspector code (eye icon, thumbnail
toggle, layer panel) that was disabled behind a feature flag.

* feat(studio): add Layer (z-index) field to design panel

Adds a scrub-enabled "Layer" field below the W/H inputs in the Layout
section. Available for all elements regardless of style editing
capability since z-index is fundamental to composition stacking order.

* docs: architecture spec for studio domain contexts, hook split, and file-size lint

* docs: implementation plan for studio contexts, hook split, and file-size lint

* refactor(studio): consolidate duplicate helpers in useDomEditSession

Remove ~370 lines of helper functions that were copied into the hook
instead of imported. All removed functions already exist in the
canonical utility files (studioHelpers, studioFontHelpers,
studioPreviewHelpers, domEditHelpers). Also removes the duplicate
local type definitions for RightPanelTab, AgentModalAnchorPoint, and
PreviewLocalPointer, and drops now-unused imports (googleFontStylesheetUrl,
importedFontFaceCss, resolveVisualDomEditSelectionTarget, DomEditViewport).

Temporarily excludes useDomEditSession.ts from the 500 LOC file-size
check until Tasks 3-5 split it into focused hooks.

* refactor(studio): extract useDomSelection from useDomEditSession

* refactor(studio): extract useAskAgentModal from useDomEditSession

* refactor(studio): extract usePreviewInteraction from useDomEditSession

* refactor(studio): extract useDomEditCommits, useDomEditSession now thin orchestrator

Split the 897-line useDomEditSession into focused hooks:
- useDomEditCommits (439 LOC): manifest commits (path offset, box size,
  rotation, manual edits reset, motion), persist operations, element delete,
  font asset resolution
- useDomEditTextCommits (329 LOC): style/text/text-field commits
- useDomEditSession (339 LOC): thin orchestrator wiring selection, agent
  modal, preview interaction, and commit hooks

All files now under 500 LOC limit. Removed the temporary lefthook
filesize exclusion for useDomEditSession.

* feat(studio): add 4 domain contexts (PanelLayout, FileManager, DomEdit, Studio)

Create context providers that wrap hook return values for prop-drilling
elimination. Each context destructures and reconstructs the value inside
useMemo so exhaustive-deps is satisfied and re-renders are minimized.

Not yet wired into App.tsx — that comes in a follow-up.

* refactor(studio): wire domain contexts, eliminate prop drilling in 4 components

Wire StudioProvider, PanelLayoutProvider, FileManagerProvider, and
DomEditProvider in App.tsx. Migrate StudioHeader, StudioLeftSidebar,
StudioPreviewArea, and StudioRightPanel to consume contexts instead
of props.

Prop counts reduced:
- StudioHeader: 13 -> 6
- StudioLeftSidebar: 19 -> 4
- StudioPreviewArea: 37 -> 11
- StudioRightPanel: 39 -> 3

Net: -118 lines, 108 props removed from call sites.

* chore: upgrade to React 19

Upgrade react and react-dom from 18.3 to 19.2.6 across the workspace.
Add resolutions/overrides in root package.json to prevent peer
dependency pins (e.g. @phosphor-icons/react) from pulling React 18.
Regenerate bun.lock.

This enables the React 19 context syntax (<Context value={...}>)
used by the new domain contexts.

* fix(studio): refresh preview after z-index change so stacking updates visually

* fix(studio): remove duplicate duration override causing oscillation

The timeline message handler set the duration twice: once via
processTimelineMessage and once via a raw durationInFrames override.
When drilled into a sub-composition, these could disagree, causing
the duration to oscillate after element deletion.

* fix(studio): use in-place iframe reload after clip delete, remove confirm dialogs

Two changes to fix duration oscillation after deleting a timeline clip:

1. Replace setRefreshKey (full Player remount) with in-place
   iframe.contentWindow.location.reload() after deleting a clip.
   The full remount triggered a chaotic re-probing cycle with multiple
   duration sources (adapter, manifest, postMessage) fighting each
   other, causing the timeline to oscillate between durations.
   In-place reload preserves the Player web component and its state.

2. Remove window.confirm dialogs from both timeline clip delete and
   DOM element delete. Undo is available so the confirmation adds
   friction without value.

* chore: gitignore docs/superpowers

* feat(studio): add favicon

* perf(studio): skip no-op state updates in timeline sync

syncTimelineElements was called 60+ times per page load, each time
triggering setElements/setDuration/setTimelineReady even when nothing
changed. This caused massive re-render churn and memory usage.

Add early-return guards to skip updates when values haven't changed.
Also fixes the duration oscillation after element delete.

* refactor(studio): split PropertyPanel.tsx (3126 LOC) into 8 focused modules

The monolithic PropertyPanel.tsx exceeded the 500 LOC filesize limit.
Split into cohesive modules by responsibility:

- propertyPanelHelpers.ts (401) — pure utility functions, shared types/constants
- propertyPanelPrimitives.tsx (357) — CommitField, MetricField, DetailField,
  SliderControl, SegmentedControl, SelectField, Section
- propertyPanelColor.tsx (371) — ColorField, ColorSlider
- propertyPanelFill.tsx (421) — ImageFillField, GradientField, asset path helpers
- propertyPanelFont.tsx (455) — FontFamilyField + font catalog helpers
- propertyPanelSections.tsx (453) — TextSection, TextFieldEditor, text controls
- propertyPanelStyleSections.tsx (411) — StyleSections (stroke, effects, clip, fill)
- PropertyPanel.tsx (347) — main component, LayerTree, re-exports for consumers

All re-exports from PropertyPanel.tsx preserved for backwards compatibility.
No behavioral changes — pure structural split.

* fix(studio): use in-place iframe reload for all timeline operations

Replace setRefreshKey with in-place iframe reload for move, resize,
and asset drop — matching delete which was already fixed. Prevents
the Player remount probe cycle that causes duration oscillation.

* perf(studio): replace 5s polling loop with event-driven adapter init

The Player's onIframeLoad used a setInterval polling loop (25 attempts
× 200ms = 5 seconds) to detect when the runtime's __player/__timeline
globals appeared. Each poll that missed triggered wasted work, and
multiple duration sources fighting during the probe cycle caused
oscillation bugs.

Replace with event-driven initialization:
1. Fast path: try initializeAdapter() immediately (works for in-place
   reloads where the adapter is already present)
2. If not ready, listen for the runtime's "state"/"timeline" postMessage
   signals and initialize on the first one
3. Single 5s timeout as safety net (replaces 25 interval ticks)

This eliminates the polling overhead, reduces setDuration/setElements
calls to exactly 1 per load, and makes the Player responsive within
one frame of the runtime being ready instead of up to 200ms later.

* fix(studio): prevent duration oscillation after element delete

Two fixes for the duration display oscillating between sub-composition
and master durations after deleting an element in the preview:

1. Clear store elements before iframe reload in handleDomEditElementDelete.
   Without this, stale pre-delete elements remain in the store and cause
   mergeTimelineElementsPreservingDowngrades to alternate between REPLACE
   and PRESERVE modes as the element count fluctuates.

2. Add 500ms cooldown on enrichMissingCompositions after timeline messages.
   The "state" handler was calling enrichMissingCompositions every ~80ms,
   which added extra elements from GSAP timelines. These fought with the
   authoritative element list from "timeline" messages (~333ms), creating
   a feedback loop where element count oscillated and triggered alternating
   merge strategies with different durations.

* fix(studio): single reloadPreview as source of truth for preview refresh

Create reloadPreview() in App.tsx that encapsulates the correct
behavior (in-place iframe reload with setRefreshKey fallback). Pass it
as the sole refresh mechanism to hooks, removing direct setRefreshKey
access from useTimelineEditing and useDomEditCommits.

James aa715ca8a0 feat(core,studio,cli): add square + square-4k canvas resolutions
The four existing presets only cover 16:9 (landscape) and 9:16 (portrait)
aspect ratios. A 1080×1080 square comp had nowhere to land at any scale:
"Auto" rendered at the comp's authored 1080×1080, and picking 1080p or 4K
mapped to a landscape/portrait preset whose aspect ratio mismatched, which
the producer's resolveDeviceScaleFactor validator rejects with
"does not match the aspect ratio of the composition".

Add `square` (1080×1080) and `square-4k` (2160×2160) to CANVAS_DIMENSIONS
in core. The existing `keyof typeof CANVAS_DIMENSIONS` derivation
extends the `CanvasResolution` union and `VALID_CANVAS_RESOLUTIONS` array
automatically, so the producer's validator, the render API route, and
the CLI `--resolution` flag pick the new presets up without further
changes.

- core: extend CANVAS_DIMENSIONS, RESOLUTION_ALIASES, and the
  htmlParser to recognize `data-resolution="square|square-4k"` and to
  infer square from equal width/height (vs. the prior "square defaults
  to portrait" tie-breaker).
- studio: extend the local ResolutionPreset / CANVAS_DIMENSIONS mirrors;
  collapse isPortraitComp into a 3-way `compAspect` helper so
  resolveResolution returns the square preset for square comps.
- cli: update --resolution help text on `init` and `render` to mention
  the new presets.
- tests: add square cases to renderOrchestrator's resolveDeviceScaleFactor
  suite (returns 1 for square→square, 2 for square→square-4k, rejects
  landscape preset on square comp), update the htmlParser test that
  previously pinned the "square→portrait" tiebreaker.

Theodor Kleynhans 5dcc89c930 feat(cli): accept ffmpeg-style rational fps (NTSC, PAL, slow-mo)
Replaces the rigid `--fps 24|30|60` whitelist with a numeric range and
adds support for ffmpeg-style fractional framerates so NTSC stays exact
end-to-end.

- `--fps 30` keeps working (integer fps)
- `--fps 30000/1001` now means exact NTSC 29.97 (not the lossy decimal)
- `--fps 24000/1001`, `--fps 60000/1001`, `--fps 25/50/120/240` all work
- Decimals like `--fps 29.97` are rejected with a friendly error pointing
  the user at the rational form, since `29.97` and `30000/1001` round
  to different framerates inside ffmpeg

Carries an `Fps = { num: number; den: number }` rational end-to-end:
RenderConfig, EncoderOptions, StreamingEncoderOptions, CaptureOptions,
DockerRenderOptions, Studio API request body, regression-harness
meta.json. The `-r` and `-framerate` ffmpeg args emit the rational form
verbatim (`30000/1001`) so no decimal round-trip happens at the encoder
boundary. Frame-interval math uses `1000 * den / num` ms (33.366… for
NTSC, 33.333… for integer 30).

Helpers live in @hyperframes/core:
- `parseFps(input: string | number): FpsParseResult` — discriminated
  parser used by both the CLI and the Studio API route
- `fpsToFfmpegArg(fps: Fps): string` — emits "30" or "30000/1001"
- `fpsToNumber(fps: Fps): number` — for arithmetic (telemetry, frame
  count, frame-index → time)

Studio API wire format accepts polymorphic `fps: number | string`:
- number → integer fps (`30`)
- string → rational (`"30000/1001"`)
Decimals are rejected; matches the same rule as the CLI.

Existing meta.json fixtures with integer `"fps": 30` continue to load
unchanged — the regression-harness validator now normalizes both number
and string inputs through `parseFps`.

Miguel Ángel b009288df7 feat(runtime): single-clock transport — eliminate pause/play audio drift (#671)
Replace the two-clock architecture (GSAP rAF ticker + HTMLMediaElement
pipeline reconciled by a 50ms polling loop) with a single TransportClock.
GSAP is always paused and seeked to clock.now() on each rAF tick.
Drift between visual timeline and audio is structurally impossible.

Architecture:

  TransportClock.now() ──rAF──▶ timeline.seek(t) + el.currentTime
       ▲
  AudioContext.currentTime (~21µs)  ← WebAudio active
       OR
  audio.currentTime (~33ms)         ← HTMLMediaElement fallback
       OR
  performance.now() (~1ms)          ← no audio

Key changes:
- TransportClock class with monotonic + audio-master clock sources
- WebAudioTransport: routes audio through AudioBufferSourceNode for
  sample-accurate scheduling, falls back gracefully to HTMLMediaElement
- rAF tick loop replaces 50ms setInterval poll; GSAP always paused
- Strict sync (40ms threshold, consecutive-sample gated) + forceSync
  on play/pause/seek transitions for sub-frame media accuracy
- Buffer-stall: visuals freeze when audio is buffering instead of
  running ahead
- Frame quantization preserved in seek/renderSeek (parity contract)

Browser-verified: 0.0ms drift after 40 pause/play cycles (was 400ms+).

Also fixes: CDN script HTML error responses in validate (pre-existing).

54 tests across clock, clock-drift, webAudioTransport, and media.

Closes #668

James a739be58b1 fix(cli): preload render.js once in renderLocal test suite to fix Windows CI
The first dynamic `await import("./render.js")` cold-load takes >5 s on
Windows runners — long enough to blow vitest's default 5 s timeout in
whichever test ran it first. Subsequent imports are <10 ms because the
module is now cached, so only test #1 ever times out.

The downstream failure is more subtle: when test #1 times out, vitest
moves on, but its leaked async function eventually hits the synchronous
`producer.createRenderJob(...)` line and pushes a stale config to
`producerState.createdJobs`. That push lands AFTER test #2's `beforeEach`
clears the array, so test #2's `createdJobs[0]` is the leaked test #1
entry instead of its own. That's why test #2 saw `browserGpuMode: 'software'`
when it expected `'auto'`.

Hoist the import into `beforeAll` (matching the pattern the existing
`parseVariablesArg` and `validateVariablesAgainstProject` describe blocks
in this file already use). Cold-load happens once outside any test's
timeout window, every test stays fast, no leaked promise can corrupt
state.

Failing run: https://github.com/heygen-com/hyperframes/actions/runs/25470257972/job/74732502915
Started failing on main with the merge of #642 (auto-detect-browser-gpu),

James f33000dd1f fix(cli): rename browserGpu → browserGpuMode in render.test.ts
Drive-by fix: hf#631 (composition flag) merged with two test calls
using `browserGpu: false`, but hf#642 (browserGpuMode auto) merged
shortly after and removed that field from RenderOptions in favour of
the tri-state `browserGpuMode`. Main has been failing typecheck since
hf#642 landed (every PR inherits the failure).

Renaming `browserGpu: false` → `browserGpuMode: "software"` matches
the new shape; both tests still verify what they were written for
(forwards entryFile / omits entryFile to createRenderJob).

Theodor Kleynhans 4e28658173 feat(cli): expose png-sequence format
The producer already supports `format: "png-sequence"` end-to-end (see
RenderConfig in renderOrchestrator.ts), but the CLI's VALID_FORMAT
validator rejects it before the flag reaches the producer. Surface it
the same way `mov` and `webm` are surfaced.

Behaviour:
- `--format png-sequence` accepted alongside mp4/webm/mov.
- Auto-output path uses no extension (FORMAT_EXT["png-sequence"] = "")
  since the producer treats outputPath as a directory of frame_NNNNNN.png.
- `printRenderComplete` sums the contained file sizes when outputPath
  is a directory, instead of reporting the platform-dependent inode
  size.
- DockerRenderOptions.format type extended; existing buildDockerRunArgs
  is unchanged because it forwards the string verbatim.

Tests:
- renderLocal forwards `format: "png-sequence"` to createRenderJob.
- buildDockerRunArgs propagates `--format png-sequence` to the
  container.

Docs:
- Rendering guide: format flag table, format comparison table, new
  "PNG sequence (no encoding)" section, "How it works" extended.
- CLI package docs: format flag table updated.

James f635deb86a feat(engine): cache probe Promise + log resolved mode + sync docs
Three follow-ups from Vai's staff-eng review:

1. Concurrent-probe race (real bug): the parallel coordinator runs N
   workers via Promise.all, so `--workers 4` on a no-GPU host fired 4
   simultaneous probe Chromes — each paying the same 240 ms launch cost.
   Cache the *Promise* (not the resolved value): first caller assigns
   the in-flight Promise, every other concurrent caller awaits the same
   one. Verified with a new test asserting all concurrent callers get
   the identical Promise reference.

2. Stale rendering.md (lines 23, 29): user-visible contract said
   "browser GPU enabled by default", which was wrong post-auto. Now
   describes the auto / hardware / software trichotomy explicitly.

3. Silent fallback: auto-mode produced no output, so a regression to
   "always falls back to software even with GPU present" would have
   been invisible in production logs. Added a single stderr line per
   process when the probe resolves: `[hyperframes] browserGpuMode auto
   → <mode> (<reason>)`. Cache hits don't re-log.

Verification:
- Engine 536/536 (incl. new concurrent-dedup test asserting Promise
  reference equality across simultaneous callers)
- CLI 256/256
- Format / lint / typecheck clean

James 2221647728 refactor(cli): unify RenderOptions on browserGpuMode tri-state
Initial PR carried a backwards-compat shim where RenderOptions had both
`browserGpu?: boolean` (for docker) and `browserGpuMode?` (for local).
Since renderLocal/renderDocker have no external callers, simplify to a
single field. The boolean → docker-args conversion now happens inline at
the one site that needs it (`browserGpu: options.browserGpuMode === "hardware"`
when handing off to dockerRunArgs).

No behaviour change. 535/535 engine + 256/256 CLI still pass.

James 67bb56c703 feat(engine): browserGpuMode "auto" — probe WebGL once, fall back to software
When the host doesn't have a usable GPU (CI containers, eval rigs without
GPU passthrough, dev VMs), Chrome's hardware-mode WebGL flags
(`--use-gl=egl/metal/d3d11`) silently leave WebGL unavailable —
`getContext("webgl")` returns null, three.js' WebGLRenderer dies, the
canvas stays black. Surfaced today by Abhay's c2v-eval failing on a
docker render of an hf bundle that uses three.js + a custom fragment
shader.

The fix that's been there: `--use-gl=angle --use-angle=swiftshader` (CPU
software WebGL, ~5-50× slower but pixel-identical). The engine already
exposed `browserGpuMode: "software"` for this. The gap was discovery —
users had to know to pass `--no-browser-gpu` on no-GPU hosts.

This change adds `browserGpuMode: "auto"` (now the CLI default for local
renders): on first launch in the process, probe Chrome with hardware
args, check `canvas.getContext("webgl") !== null`, cache the result.
~1-2 s on first render, free on every subsequent render in the same
worker. Hardware GPUs keep their fast path; no-GPU hosts get SwiftShader
without ceremony.

Behaviour matrix:
- No flag, no env, local       → "auto" (NEW default)
- `--browser-gpu`              → "hardware" (force; errors if no GPU)
- `--no-browser-gpu`           → "software" (force SwiftShader)
- `PRODUCER_BROWSER_GPU_MODE`  → "hardware" / "software" / "auto" / unset
- Docker mode                  → forced "software" (unchanged)

Engine-config default stays "software" (conservative for embedders); the
"auto" default lives in the CLI's `resolveBrowserGpuForCli` so producer
embedders aren't surprised by a probe-on-launch.

Also adds `--enable-unsafe-swiftshader` to the software flag set —
Chrome 120+ deprecated implicit SwiftShader fallback and emits a
deprecation warning unless the flag is set explicitly. Despite the
"unsafe" name this is exactly the pre-deprecation behaviour; the rename
is about Chrome's threat model on the open web, not about the rendering
itself.

Verification:
- Engine 535/535 + CLI 256/256 (incl. new probe tests + tri-state CLI test)
- Empirical: probe on this no-GPU devbox returns "software" in 240 ms,
  cached 0 ms on subsequent calls
- Format / lint / typecheck clean across all packages

Miguel Ángel 35e71cb3f0 fix(cli): bypass stale cache on tag-based registry lookup (#648)
The add command's tag fallback (e.g. `hyperframes add html-in-canvas`)
uses the same 24h cached manifest as single-item lookups. When new items
are added to the registry, the stale cache returns an incomplete item
list, causing tag resolution to find zero matches.

Pass skipCache: true in the tag fallback path so it always fetches the
latest manifest from the registry.

Miguel Ángel 20c1341cc8 feat(cli): name-or-tag resolution for hyperframes add
hyperframes add now auto-detects whether the argument is a single
block name or a tag. No --tag flag needed:

  hyperframes add html-in-canvas  # installs all 7 html-in-canvas blocks
  hyperframes add captions        # installs all 5 caption blocks
  hyperframes add vfx-shatter     # installs one block

When the name doesn't match a registry item, the CLI falls back to
tag-based resolution and bulk-installs all matching blocks.

Also fixes tag assignments:
- VFX blocks tagged "html-in-canvas" (not "vfx")
- Caption blocks tagged "captions" only (no html-in-canvas)

  hyperframes add --tag captions  # installs all 5 caption blocks

The resolver loads each item's full manifest to check tags, then
installs matching blocks sequentially. Failed items are skipped
with a warning so one broken block doesn't abort the batch.

Also supports JSON output for CI: hyperframes add --tag vfx --json

Rames JussoandClaude Opus 4.7 dfca302d37 fix(bundler): runtime mode opt-in, ASI-safe joinJsChunks, prune dead subs
Per @vai-bot's review on hf#641:

Important #1: dead `src=""` substitution sites
=============================================

Now that `bundleToSingleHtml` inlines the runtime IIFE by default, the empty
`src=""` placeholder is never emitted in the no-env-var path — the 5 downstream
substitution sites that grep for `src=""` were dead.

Two of them (studio dev server + studio vite preview) genuinely WANT the
placeholder so they can hot-reload a local /api/runtime.js endpoint without
re-inlining ~150 KB on every composition edit. Three of them (CLI validate,
snapshot, layout) were just doing the same inlining the bundler already does.

Resolution:
- Add a `runtime: "inline" | "placeholder"` option to `BundleOptions`. Default
  is "inline" (matches the self-contained-bundle promise the function name
  makes). The two studio surfaces explicitly pass `{ runtime: "placeholder" }`
  to opt in.
- studioServer.ts + studio/vite.config.ts: pass the option, keep their
  existing string-replace logic unchanged.
- validate.ts + snapshot.ts + layout.ts: delete the now-redundant runtime
  substitution code (regex never matches the new inlined-runtime shape).

Important #2: joinJsChunks ASI hazard
======================================

The new helper appended `;` to chunks not already ending in `;` and joined
on `\n`. If a chunk ended with a `// line comment`, the appended semicolon
was eaten by the comment, leaving the next chunk's first statement attached
to the previous chunk's last expression — exactly the ASI hazard the helper
exists to prevent.

Fix: append `\n;` instead of `;` for chunks not already terminated. The
newline closes the line comment, the standalone `;` becomes the statement
separator. For typical chunks (already ending in `;`), output is unchanged
— still clean `\n`-joined chunks with no bare-semicolon lines.

Also added a trailing `;` to `wrapScopedCompositionScript`'s IIFE close
(`})()` → `})();`) so composition scripts join cleanly without falling
through to the `\n;` fallback.

New test: regression guard at the chunk boundary verifies every inline
script body in the bundle parses cleanly via esbuild even when a source JS
file ends with a line comment.

Verification
============

- `bun run --filter @hyperframes/core test` — 653/653 pass
- `bun run --filter @hyperframes/cli test` — 243/243 pass
- `bun run --filter @hyperframes/{core,cli,studio} typecheck` — clean
- `bunx oxfmt --check` + `bunx oxlint` on all touched files — clean

JamesandClaude Opus 4.7 a707b6a882 fix(cli): pin inverse-alpha invariants, harden encoder stdin
- Extract applyMask helper from postprocess and add 5 unit tests pinning
  the contract this PR is selling: fg.alpha + bg.alpha === 255 per pixel,
  RGB triples byte-identical between fg and bg, and bg=null path leaves
  the bg buffer untouched. Without these, a future postprocess change
  (mask threshold, premultiplied alpha, gamma) could silently break the
  inverse-alpha relationship and the existing plumbing tests would all
  still pass.
- Add stdin 'error' listener inside spawnFfmpeg. If either encoder dies
  mid-render, Node emits an unhandled error on the dead writable on the
  next .write() and crashes the CLI before waitForExit's reject path
  can surface the encoder's stderr tail. Doubled encoder count = doubled
  failure surface, so this is worth pinning down.
- Tighten stdio param to a 3-tuple so an accidental 1-element array fails
  at type-check.
- Sharpen backpressure comment: write→true means "highWaterMark not
  exceeded," not "libuv flushed." Reuse-without-corruption is safe only
  because session.process is slow enough that libuv drains in between.

Miguel Ángel 21ec5f800a fix(cli): use size-adaptive timeouts for publish uploads (#635)
## Summary
- Replace the flat 30s upload timeout with a size-adaptive calculation: `max(120s, bytes / 500KB/s)`
- Metadata requests (presigned URL, complete) keep the original 30s timeout
- Companion to the backend change removing the 64 MB upload limit in experiment-framework

## Context
With the backend size limit removed, large projects (78 MB+) need proportionally longer to upload. A 78 MB project now gets ~164s, a 500 MB project ~17 min. The old 30s timeout would abort any upload over ~15 MB on a typical connection.

## Test plan
- [x] All 4 existing vitest tests pass
- [x] Build succeeds, no type errors
- [x] Lint + format pass (oxlint + oxfmt)
- [x] Timeout values verified for 10/78/200/500/1000 MB archives

JamesandClaude Opus 4.7 688052d368 fix(cli): correct sharp 3-channel mask + BT.709 + quality presets in remove-background
- inference.ts: force `.toColourspace("b-w")` on the resized mask. Sharp upcasts
  the 1-channel raw input to RGB-interleaved during resize, so `fullMask[i]`
  was reading R,G,B,R,G,B... of pixels 0..691199 instead of the alpha for all
  2,073,600 pixels. Visible symptom: horizontal scanline alpha artifact in
  every transparent webm — the avatar appeared semi-transparent throughout.
- pipeline.ts: add BT.709 + limited-range colorspace tags so Chrome's YUV→RGB
  matches the source mp4 (without these, ffmpeg's default RGB→YUV is BT.601
  and skin tones drift visibly when the cutout is overlaid on its source).
- pipeline.ts: add Quality preset type ("fast"/"balanced"/"best" → CRF 30/18/12).
  Default raised from CRF 30 → 18 ("balanced") so the most common pattern
  (text-behind-subject) works out of the box without visible doubling.
- remove-background.ts: wire `--quality` flag with validation, +2 examples.
- Tests: BT.709 tags present, quality preset → CRF mapping, default is balanced.

at hyperframes-cli — directly undercutting the description-trigger
goal of the split:

- skills/hyperframes/SKILL.md description ended with "For CLI commands
  (init, lint, preview, render, transcribe, tts) see the
  hyperframes-cli skill." Now splits the redirect: dev-loop commands
  (init, lint, inspect, preview, render) → hyperframes-cli; asset
  preprocessing (tts, transcribe, remove-background) →
  hyperframes-media.
- packages/cli/src/templates/_shared/CLAUDE.md is the skills table
  baked into every project bootstrapped by `hyperframes init`. Its
  hyperframes-cli row still listed transcribe/tts. Trimmed to the
  dev-loop commands and added a hyperframes-media row beside it, so
  new projects pick up the correct mapping.

Also caught by greppping for stale skill lists:

- .codex-plugin/plugin.json longDescription bundled transcribe/tts
  into "use the CLI for ...". Split into "use the CLI for the dev
  loop (init/preview/render), preprocess assets
  (tts/transcribe/remove-background)" so the Codex plugin store
  surface matches reality.

Confirmed `npx hyperframes skills` shells out to `npx skills add
heygen-com/hyperframes --all` (packages/cli/src/commands/skills.ts),
so the skill list is read dynamically from the repo and picks up
hyperframes-media without code changes.

Miguel Ángel 7affa4a4e9 fix: handle player loop and render exit (#617)
## Problem

Two newly reported runtime issues break common local workflows:

- Fixes #615: `<hyperframes-player loop>` reaches the final frame, receives a paused runtime state, and stays paused instead of wrapping.
- Fixes #616: `hyperframes render` can finish writing the output and print `Render complete`, but still remain alive when a non-essential handle keeps Node's event loop open.

The catalog block also used old VPN branding and slug/file names that should now be neutral. Renaming registry items also exposed a catalog-preview CI bug where deleted registry paths were treated as still-renderable changed items.

## What this fixes

- detects player completion from the previous playing state before mutating the parent `_paused` cache from the runtime's final state
- wraps looping players back to `0` and immediately resumes playback even when the runtime posts `isPlaying: false` at the end frame
- keeps non-looping players dispatching the existing `ended` flow
- lets the CLI command path schedule a short unref'd `process.exit(0)` after a successful local or Docker render
- keeps `renderLocal()` importable for tests and internal callers without forcing process exit unless the CLI command explicitly opts in
- adds regression coverage for the player loop end-state and successful render exit scheduling
- renames the VPN catalog block to `vpn-youtube-spot` across registry, docs route, install command, composition filename, asset filename, composition id, and timeline key
- keeps visible block/app copy friendly and named `VPN`
- updates catalog-preview CI to ignore deleted registry paths when computing changed preview items

## Root cause

The player message handler updated `_paused = !data.isPlaying` before checking for end-of-composition loop behavior. The runtime's legitimate final-frame state has `isPlaying: false`, so the existing `currentTime >= duration && !paused` loop branch was skipped.

For render completion, the CLI returned after `printRenderComplete()`, leaving process lifetime entirely to Node's active handles. Most local renders in this checkout drain cleanly, but the reported npm flow shows a sleeping parent process after output is already complete. The CLI now schedules a short unref'd successful exit only from the command path after user-visible render work has completed.

The catalog block issue was content/metadata drift: registry/docs/code identifiers still used the old slug, so the catalog route, install command, composition id, file names, and source prompt did not match the requested neutral VPN naming. The preview workflow used plain `git diff --name-only`, which includes deleted paths during renames; it now filters to added/copied/modified/renamed live paths.

## Verification

### Browser verification

- Built the player bundle and served a real local reproduction using the built player, the built HyperFrames runtime, and GSAP.
- Used `agent-browser` to open the page, click `Seek near end`, and wait through the end-frame transition.
- Verified the browser state after playback: `stuck=false`, `looped=true`, and playback continued after wrapping from ~4s back to the start.
- Served `registry/blocks/vpn-youtube-spot/vpn-youtube-spot.html` locally, used `agent-browser` to seek the timeline, and verified `window.__timelines` contains `vpn-youtube-spot`, not `goonvpn-youtube-spot`.
- Served the docs locally with Mintlify, opened `/catalog/blocks/vpn-youtube-spot`, and verified the install command is `npx hyperframes add vpn-youtube-spot` with no old slug visible.

### Composition verification

- `bun run --filter @hyperframes/cli dev lint /var/folders/3n/hxk3qmnd0tl284jtcy66w6dw0000gn/T/hf-vpn-renamed-w027if` returned 0 errors and 1 existing large-composition warning.
- `bun run --filter @hyperframes/cli dev validate /var/folders/3n/hxk3qmnd0tl284jtcy66w6dw0000gn/T/hf-vpn-renamed-w027if --timeout 5000` returned 0 console errors; it reported existing non-fatal contrast audit warnings from the block styling.
- `bun run --filter @hyperframes/cli dev render /var/folders/3n/hxk3qmnd0tl284jtcy66w6dw0000gn/T/hf-vpn-renamed-w027if --output /tmp/hf-vpn-renamed-proof.mp4 --fps 30 --quality draft --workers 1 --no-browser-gpu` completed successfully.
- `ffprobe -v error -show_entries format=duration,size -of default=noprint_wrappers=1 /tmp/hf-vpn-renamed-proof.mp4` reported `duration=7.000000`.

### Render verification

- Ran a real 1920x1080, 5-second render with `--gpu --workers 6 --quality draft --fps 24`.
- Verified the command printed `Render complete` and the parent process exited with code `0` in the wrapper: `RENDER_EXIT_PROOF code=0 signal=null sawComplete=true`.

## Notes

- I could not reproduce the exact indefinite #616 render hang on this checkout; both tiny and GPU/6-worker local renders exited cleanly before and after the patch. The CLI guard still addresses the reported leaked-handle failure mode because it fires only after successful render completion.
- Browser proof artifacts were local-only: `/tmp/hf-player-loop-proof-final.png`, `/tmp/hf-player-loop-proof-final.webm`, `/tmp/hf-vpn-code-rename-proof.png`, `/tmp/hf-vpn-code-rename-proof.webm`, `/tmp/hf-vpn-doc-route-rename-proof.png`, and `/tmp/hf-vpn-doc-route-rename-proof.webm`.
- The renamed composition render artifact was local-only: `/tmp/hf-vpn-renamed-proof.mp4`.
- The CLI exit guard is only enabled by the `render` command's top-level local/Docker calls. Direct test/internal calls to `renderLocal()` do not force process exit unless they pass `exitAfterComplete: true`.

JamesandClaude Opus 4.7 21243b6957 docs: lead with shape contrast for variable attributes
Follow-up on the PR #603 review. The previous fix named both attributes
but didn't make their distinct shapes / roles obvious; a reader could
still wonder "are these two views of the same data?". Now the doc
opens with the shape contrast (array of declarations vs object of
values) and the section closes with a numbered precedence layering so
the merge order is unambiguous.

- compositions.md: replaced the bullet list with a shape-first
  description ("JSON array of declarations" vs "JSON object keyed by
  variable id"), an explicit "they aren't redundant" line, and a
  numbered list of the three precedence layers (declared default →
  host data-variable-values → CLI --variables).
- skills/hyperframes-cli/SKILL.md: highlighted the same shape contrast
  inside the parametrized-renders paragraph (declarations array vs
  values object).

JamesandClaude Opus 4.7 22bcd7a18b docs: clarify declaration vs override attributes (PR #603 review)
James pointed out (compositions.md:33, SKILL.md:121) that the prose
referenced `data-variable-values` while the example below showed
`data-composition-variables`, leaving readers to wonder if the two
names referred to the same thing. They don't: one declares, the other
overrides per-instance. Both are now named at first mention and the
declare-vs-override split is called out explicitly.

- packages/cli/src/docs/compositions.md: replaced the single intro
  sentence with a two-bullet list ("data-composition-variables
  declares, data-variable-values overrides per-instance") and a
  follow-up explaining where the CLI fits in.
- skills/hyperframes-cli/SKILL.md: rewrote the parametrized-renders
  paragraph so declaration (data-composition-variables) and override
  (--variables) are distinct sentences, with the per-instance attribute
  parenthetical for completeness.

JamesandClaude Opus 4.7 211a9214d0 docs(skills): teach agents the variables system across SKILL.md + docs
Distribution PR for the variables feature stack: tells agents how to
declare, read, and override variables across the four authoring
surfaces.

skills/hyperframes/SKILL.md:
- Added data-variable-values + data-composition-variables to the
  data-attributes tables (host element + <html> root respectively).
- New "Variables (Parametrized Compositions)" section right after
  "Composition Structure". Three-step pattern (declare / read /
  override), full worked example with enum variable, sub-comp
  per-instance pattern with two hosts sharing a source, and rules
  of thumb (always provide defaults; read once, not in frame loops;
  use --strict-variables in CI; type validation behavior).

skills/hyperframes-cli/SKILL.md:
- Added --variables, --variables-file, --strict-variables to the
  render flag table.
- Short paragraph below the table explaining the parametrized-render
  pattern with a forward reference to the hyperframes skill.

docs/packages/core.mdx:
- Added a code snippet showing getVariables<T>() inside a composition
  and validateVariables/formatVariableValidationIssue for tooling.

packages/cli/src/docs/compositions.md (the in-CLI `npx hyperframes
docs compositions` content):
- Replaced the hand-rolled JSON.parse(host.dataset.variableValues)
  pattern with the modern getVariables() pattern.

This is PR 4 of the 4-PR stack. The openai/plugins mirror is a
separate follow-up.
