refactor(core): remove redundant as casts using window.d.ts declarations
window.d.ts already declares __timelines, __player, __playerReady,
and __renderReady on the global Window interface. The casts in
init.ts and init.test.ts were re-asserting the same types.
- Add __hfRuntimeTeardown to window.d.ts (used 6x in init.ts)
- Remove runtimeWindow cast variable from init.ts — use window directly
- Remove all (window as Window & { __player?: ... }).__player casts
from init.test.ts — window.__player is already typed as PlayerAPI
- Remove all (window as Window & { __timelines?: ... }).__timelines
casts from init.test.ts — window.__timelines is already typed
- Remove (window as Window & { __playerReady/renderReady }}) casts
from init.ts — already declared globally

fix(core,cli): address review — guard __renderReady, drop pre-quantization, add tests
- Guard __renderReady with `if (state.capturedTimeline)` in all three paths (setTimeout(0) and .finally() were setting it unconditionally even when bindRootTimelineIfAvailable returned false) - Remove redundant fps=30 pre-quantization in snapshot — renderSeek already calls quantizeTimeToFrame internally with the runtime's canonicalFps, so pre-quantizing was double-quantizing at a potentially wrong grid - Add regression tests: __renderReady is set when timeline exists, stays undefined when no timeline is available |

fix(core,cli): defer __renderReady until root timeline is bound
The runtime set __renderReady at the same time as __playerReady, before the root timeline was bound. Consumers waiting for __renderReady (the render-safe signal) could observe a player with no captured timeline, making renderSeek a no-op. Root cause: init.ts set both flags together, but timeline binding happens later — synchronously via bindRootTimelineIfAvailable(), via a deferred setTimeout(0) for bundled compositions, or asynchronously via loadExternalCompositions(). Fix in init.ts: - Remove __renderReady from the __playerReady assignment - Set it after bindRootTimelineIfAvailable() when timeline is found - Set it in the setTimeout(0) deferred path - Set it in the external compositions .finally() path Fix in snapshot.ts: - Wait for __renderReady (truthful signal) not __timelines - Use renderSeek() with frame quantization, not seek() - Tick the GSAP ticker after seeking - Await document.fonts.ready before capturing Closes #1047 |

fix(core): set explicit dimensions on data-hf-inner-root wrapper
The prepareFlattenedInnerRoot function creates a wrapper div when inlining sub-compositions. This wrapper had no width/height, which broke CSS height:100% chains — any sub-composition using percentage heights with flexbox centering would collapse to 0px and render content at the top instead of centered. Read data-width/data-height from the inner root and set matching pixel dimensions on the wrapper's inline style. Applied in both the compiler (server-side bundling) and the runtime (browser-side composition loader). Adds a producer regression test with a centered card sub-composition that fails without this fix. |

fix(studio): stop composition fetch-404 flood and cap error telemetry
Two fixes for the 3M+ unhandled_promise_rejection events/day spike: 1. Filter: suppress "Error fetching ... 404" rejections from composition code — these are asset-not-found content errors, not Studio bugs. 2. Rate-limit: cap both error and rejection telemetry at 50 per session. After the cap, emit a single *_cap_reached event so we know capping occurred without generating unlimited events. 3. Root cause: webAudioTransport now checks response.ok before decode and caches failed URLs in _failedSrcs so repeat ticks don't re-fetch the same 404 on every playback frame. Also add playground/ to fallow ignorePatterns — local experiment directory was tripping the audit gate. |

feat: data-timeline-locked + fix font loss in sub-compositions
Timeline locking: - Add data-timeline-locked attribute support — fully disables move, trim-start, and trim-end in Studio for clips that carry this attr - Runtime propagates the attribute from inner composition root to host element so component authors control it from their HTML - All 15 caption components in the registry now carry the attribute Font fix: - Extract <link rel="stylesheet"> and <link rel="preconnect"> from sub-composition <head> alongside existing <style>/<script> extraction - Fixes caption components (and any sub-comp using Google Fonts via <link> tags) losing their font-family when loaded as sub-compositions - Applied in both runtime (compositionLoader) and compiler (inlineSubCompositions) paths |

fix(studio): enable timeline resize for all elements, improve perf and UX
Enable trim-start and trim-end for all authored timeline elements (divs, sections, compositions) — not just video/audio/img. The deterministic-window gate was overly restrictive since all non-implicit elements have authored data-start/data-duration that define their timeline window. Replace iframe reload after resize/move with direct DOM attribute patching via patchIframeDomTiming(). This eliminates playhead-jump-to-zero, visual blinking, and race conditions from file-watcher echoes. File persistence runs in a serialized background queue (persistTimelineEdit + enqueueEdit) so rapid edits don't overwrite each other. Add mediabunny-based media probe service (mediaProbe.ts) for fast metadata extraction from file headers. Timeline elements missing sourceDuration are enriched asynchronously without waiting for DOM loadedmetadata events. Tune the runtime media preloader: lower lazy threshold from 6 to 3 clips, add 3s lookbehind window for reverse scrub, adaptive promoted-clip cap. Deduplicate getTimelineEditCapabilities — computed once in TimelineCanvas and passed as a prop to TimelineClip instead of recomputing per clip. Remove dead PlaybackAdapter re-export from useTimelinePlayer — all consumers import directly from playbackTypes. |

fix: activate nested child timelines during renderSeek
The renderSeek override in init.ts called seekTimelineAndAdapters() which only did rootTimeline.totalTime(t) without activating child timelines. GSAP does not propagate totalTime() to internally paused children. Also simplifies pollSubCompositionTimelines to always call rebind when timelines are ready, removing the before/after count comparison that could skip the rebind on fast page loads. |

test: add regression fixture for sub-comp #ID selector scoping divergence
The producer inlining path strips the inner root element (taking innerHTML when compId matches), losing the id attribute. The bundler path preserves it via flattenInnerRoot + data-hf-authored-root-id. This causes #ID selectors in sub-comp CSS and GSAP to fail silently during render while working in preview. Adds a minimal fixture with a sub-comp using #intro scope to catch this divergence in future compiler changes. |

refactor: drop unused exports detected by fallow auto-fix
Run `fallow fix --auto-fixable` to remove `export` keywords from symbols fallow's reachability analysis identifies as unused. Keeps only the cases where the symbol is still referenced internally in its own file (so removing `export` doesn't surface a new oxlint `no-unused-vars` error). Result: fallow dead-code findings drop from 276 → 208 (68 fewer unused exports), with no behavior change — each symbol is still defined and used exactly the same way within its file. Reverted ~20 files where fallow's auto-fix would have created cascading "declared but never used" lint errors — those are cases where the symbol isn't used at all, and properly cleaning them up means deleting the declaration, not just dropping `export`. Better to land that as a separate, narrower PR rather than mixing it into a mechanical de-export. Also reverted four false positives where fallow missed real consumers: - `captureCost.ts` (renderOrchestrator has two separate import blocks from the same module; fallow only saw the first) - `propertyPanelHelpers.ts`, `domEditingLayers.ts` (real internal uses fallow's reachability missed) - `render.ts` (functions imported via `await import()` dynamic import, which fallow's static analysis doesn't follow) Test plan: bun run --filter '*' typecheck (clean), oxlint + oxfmt clean, cli/core/studio/engine vitest suites pass (335 + 917 + 576 + 605 tests). |

fix(core): remove late-bind polling from runtime — engine handles it
The setInterval-based late-bind polling in init.ts caused visual regressions across all style-prod tests. Even with the sawMissing guard, the mere presence of the interval registration altered event loop timing enough to shift rendered frames. The engine's pollSubCompositionTimelines + conditional __hfForceTimelineRebind already handles async timeline detection for renders. The runtime only needs to expose the rebind hook — it shouldn't poll on its own. For studio preview of async compositions, the engine's rebind call (via __hfForceTimelineRebind) is the correct mechanism. |

fix(core): only rebind timelines when late arrivals were actually detected
The late-bind polling was unconditionally rebinding on its first check even when all timelines were already present, causing visual regressions across style-prod tests. Now tracks sawMissing flag — only rebinds if the poll previously detected missing timelines that subsequently appeared. Compositions with synchronous timeline registration exit the poll immediately with no side effects. |

fix: regression fixes — conditional rebind + updated compilation baselines
1. Only call __hfForceTimelineRebind() when the timeline poll actually had to wait (pollDuration > 2 intervals). For compositions with synchronous timeline registration, the rebind was unnecessary and shifted render timing, causing PSNR regressions in chat and gsap-letters-render-compat. 2. Regenerate compiled.html baselines for missing-host-comp-id and overlay-montage-prod to match the new flattenInnerRoot behavior (data-composition-id stripped from inlined inner roots, replaced with data-hf-authored-id). 3. Add late-bind polling to runtime init.ts — after external compositions load, poll for 5s to detect async timelines that register after initial binding (e.g. from fetch callbacks). |

fix(engine,core): wait for async timelines and force rebind before capture
Two fixes for compositions that register timelines after async data loading (e.g. fetch for TopoJSON map data): 1. engine/frameCapture: remove the hosts.length <= 1 early return so the timeline readiness poll runs for ALL compositions, not just multi-composition galleries. Single-composition pages with async setup were silently skipped. 2. core/runtime/init: expose window.__hfForceTimelineRebind() which resets childrenBound and re-runs bindRootTimelineIfAvailable(). The renderer calls this after all timelines are confirmed present, ensuring the root player discovers late-registered timelines from fetch callbacks. Without these fixes, compositions using fetch() to load data at runtime would render blank frames because the root player bound timelines before the async setup completed, and seek() never reached the unbound composition timeline. |

fix(runtime): hold external sub-compositions in render mode
PR #917 fixed visibility clamping for external sub-compositions in preview mode by checking data-composition-src. However, the producer's htmlCompiler strips that attribute during inlining without setting the data-composition-file marker that the core bundler sets. This caused the runtime to still clamp duration to Math.min(authored, live) in rendered output. Two fixes: - Runtime: also check data-composition-file (set by the core bundler after inlining) - Producer: set data-composition-file before removing data-composition-src, matching the core bundler's behavior Closes #911 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> |

fix: ship lottieReadiness + guard studio import.meta.env for non-Vite consumers (#861)
## Summary
Two small fixes that together make `@hyperframes/core` + `@hyperframes/studio` consumable from non-Vite hosts (Next.js / Turbopack, Node, etc.).
### 1. `core`: ship the missing `lottieReadiness` module
The `"./runtime/lottie-readiness"` subpath export in `@hyperframes/core` claims to ship at `./dist/runtime/adapters/lottieReadiness.js`, but that file is missing from the published 0.6.6 and 0.6.7 tarballs. Consumers that import the subpath — most notably `@hyperframes/studio`'s `Player.tsx` — fail to resolve the module and break downstream builds.
**Root cause:** `packages/core/tsconfig.json` excludes `src/runtime` (those files run in a browser context and are bundled separately into the IIFE artifact). Since nothing in the included tree imports `lottieReadiness.ts`, tsc never emits a compiled output, and the file silently goes missing from the publish.
**Fix:** `lottieReadiness.ts` is a pure helper — takes `unknown`, returns `boolean`, no DOM/`window` dependencies. It doesn't belong in `src/runtime/` in the first place; the runtime-exclude rule rightly caught it. Move it to `src/lottieReadiness.ts` so the standard library build picks it up.
The subpath export **name** stays `"./runtime/lottie-readiness"` — only the exports map's underlying file path changes — so existing consumers (studio) don't need any code change.
### 2. `studio`: guard `import.meta.env` for non-Vite hosts
`packages/studio/src/components/editor/manualEditingAvailability.ts` unconditionally reads `import.meta.env`. That's a Vite-only extension; in plain ESM hosts (Next.js / Turbopack, Node, jest in some configs) `import.meta` exists but `import.meta.env` is `undefined`. Reading any property off undefined throws at module evaluation time, so the studio fails to load the moment a non-Vite host imports anything from `@hyperframes/studio`.
Guarded the read so the module is loadable everywhere; outside Vite, every flag falls back to its declared default, preserving Vite behavior.
### Changes
**core:**
- `mv src/runtime/adapters/lottieReadiness.{ts,test.ts}` → `src/`
- Update `src/runtime/adapters/lottie.ts` re-export path
- Update `package.json` + `publishConfig.exports` to point at the new dist path (`./dist/lottieReadiness.{js,d.ts}`)
**studio:**
- One-line guard in `manualEditingAvailability.ts:30` with explanatory comment
## Test plan
- [x] `pnpm typecheck` (core, studio) — clean
- [x] `bun run build` (core) — `dist/lottieReadiness.{js,d.ts}` now present
- [x] `bunx vitest run` (core) — 862/862 passing
- [x] `bun run typecheck` (studio) — clean, resolves moved file via subpath export
- [ ] Publish 0.6.8 and verify the tarball contains `dist/lottieReadiness.js`
- [ ] Verify a non-Vite ESM consumer (e.g. a Next.js / Turbopack app) imports `@hyperframes/studio` without `import.meta.env` errors

fix(player): correct playback rate for direct-timeline and audio-clock paths (#849)
## Summary - **Direct-timeline path** (GSAP compositions with `window.__timelines`): The player drives these via `DirectTimelineAdapter`, bypassing postMessage entirely. Rate changes sent `set-playback-rate` to the iframe but had no receiver — GSAP's `timeScale()` was never called. Fix: add optional `timeScale?` to `DirectTimelineAdapter` and call `this._directTimelineAdapter?.timeScale?.(rate)` in `attributeChangedCallback`. GSAP timelines expose `timeScale` natively, no composition changes required. - **Audio-clock path** (compositions with audio): Three bugs caused `TransportClock` to always run at 1x when an audio element or WebAudio context drove the clock: 1. `schedulePlayback` was called without the `playbackRate` arg (defaulted to 1). 2. `onSetPlaybackRate` and `player.setPlaybackRate` didn't call `webAudio.setRate()`. 3. `TransportClock.attachAudioSource` divided by `this._rate` instead of `el.playbackRate`, cancelling the rate multiplier. - Adds 2 regression tests to `clock.test.ts` covering the corrected audio-clock formula. ## Test plan - [ ] Unit tests: `bun run --cwd packages/core test` — 861/861 pass - [ ] Browser verification (Playwright headless, GSAP direct-timeline composition): - 1x speed → ratio 0.972 ✓ - 2x speed → ratio 1.965 ✓ - 0.5x speed → ratio 0.490 ✓ 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(player): drive composition ticks from widget-frame rAF via postMessage (#805)
Chromium throttles requestAnimationFrame in deeply nested cross-origin iframes. In Claude desktop (Electron), the composition iframe's own rAF loop stalls, so GSAP is never seeked and animation freezes even when TransportClock.isPlaying() is true. The correct fix is to drive ticks from the widget-frame rAF, which lives one level up and is not subject to the same throttling. When play() takes the runtime bridge path (no direct timeline adapter), the player now starts a parent-frame rAF loop that sends "tick" postMessages to the composition iframe on every frame. The runtime's control bridge handles "tick" by calling seekTimelineAndAdapters(clock.now()) if the clock is playing — identical to what transportTick does on each rAF, just driven from outside. The composition iframe's own rAF loop is unchanged and keeps running normally in standard browsers. Seeking GSAP twice per frame is idempotent, so there is no regression on claude.ai or any other non-throttled environment. Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> |

feat(core): add TypeGPU/WebGPU runtime adapter (#755)
* feat(core): add TypeGPU/WebGPU runtime adapter
Adds a deterministic seek adapter for compositions that render with
TypeGPU or raw WebGPU. Follows the same push+poll pattern as the
Three.js adapter:
- Sets `window.__hfTypegpuTime` on every seek so render loops can
poll it instead of `performance.now()`.
- Dispatches a `"hf-seek"` CustomEvent on `window` so compositions
can imperatively re-render a single frame at the new seek position.
Compositions listen for the event and update their time uniform:
```js
window.addEventListener("hf-seek", (e) => render(e.detail.time));
```
Works with TypeGPU (docs.swmansion.com/TypeGPU) and raw WebGPU alike.
No assumptions are made about pipeline construction — multiple canvases
or renderers are supported by sharing the same event.
- 9 unit tests, all pass
- wired in init.ts adapter array
- `__hfTypegpuTime` declared in window.d.ts
* fix(core): deduplicate hf-seek dispatch across GPU adapters
Both three and typegpu adapters previously dispatched the same
"hf-seek" CustomEvent independently, causing any composition that
registered a listener to receive two events per seek tick — doubling
per-scrub GPU work even though the renders are idempotent.
Fix: extract a shared `dispatchSeekEvent` helper (seek-dispatch.ts)
that deduplicates by exact float equality within the same synchronous
call stack. Both adapters now call this helper instead of dispatching
directly.
Also adds:
- `resetSeekDispatchState()` export for test isolation
- `beforeEach` reset in three.test.ts and typegpu.test.ts
- New typegpu test: "duplicate seek to same time fires event only once"
- Docstring additions to typegpu.ts: render-mode determinism contract
(await device.queue.onSubmittedWorkDone()) and navigator.gpu feature
detection guidance for composition authors
* feat(core): video-texture render compat + TypeGPU skill
Adds the missing pieces for video-backed WebGPU effects in render mode:
- `video-texture-compat.ts`: monkey-patches `GPUQueue.copyExternalImageToTexture`
to detect the engine's injected `<img class="__render_frame__">` siblings and
transparently substitute them for `<video>` sources. Headless Chrome can't
supply decoded video frames to WebGPU, but the engine's pre-extracted frame
images work. Falls through to the original path in preview mode.
- `patchVideoTextureCompat()` wired in init.ts after adapter array creation.
- `skills/typegpu/SKILL.md`: full authoring guide for TypeGPU/WebGPU compositions
covering contract, timeline registration, video-backed effects, frosted blur
via downsample pass, WGSL patterns, and deterministic rendering.
* test(producer): add typegpu-adapter regression test
Self-contained WebGPU composition with:
- Procedural gradient background (no video dependency)
- Animated ring driven by hf-seek time uniform
- Pulsing center glow
- Two GSAP-driven captions testing adapter sync
Verifies the TypeGPU adapter's hf-seek → WebGPU render pipeline
produces deterministic frames. workers: 1 for consistency.
Note: output.mp4 baseline needs to be generated in CI — the local
Docker image can't launch Chrome (ARM/x86 mismatch on Mac).

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. - `bun --filter @hyperframes/studio test src/utils/editHistory.test.ts src/utils/editHistoryStorage.test.ts src/hooks/usePersistentEditHistory.test.ts src/utils/studioFileHistory.test.ts` -> 4 files pass, 15 tests pass - `bun --filter @hyperframes/studio test` -> 26 files pass, 289 tests pass - `bun --filter @hyperframes/studio typecheck` - `bunx oxlint packages/studio/src/App.tsx packages/studio/src/icons/SystemIcons.tsx packages/studio/src/hooks/usePersistentEditHistory.ts packages/studio/src/hooks/usePersistentEditHistory.test.ts packages/studio/src/utils/editHistory.ts packages/studio/src/utils/editHistory.test.ts packages/studio/src/utils/editHistoryStorage.ts packages/studio/src/utils/editHistoryStorage.test.ts packages/studio/src/utils/studioFileHistory.ts packages/studio/src/utils/studioFileHistory.test.ts` -> 0 warnings, 0 errors - `bunx oxfmt --check packages/studio/src/App.tsx packages/studio/src/icons/SystemIcons.tsx packages/studio/src/hooks/usePersistentEditHistory.ts packages/studio/src/hooks/usePersistentEditHistory.test.ts packages/studio/src/utils/editHistory.ts packages/studio/src/utils/editHistory.test.ts packages/studio/src/utils/editHistoryStorage.ts packages/studio/src/utils/editHistoryStorage.test.ts packages/studio/src/utils/studioFileHistory.ts packages/studio/src/utils/studioFileHistory.test.ts` - `git diff --check` - `bun run --filter @hyperframes/core build:hyperframes-runtime` before commit hook, because the clean worktree needed the ignored runtime-inline artifact for typecheck - Lefthook pre-commit -> lint, format, typecheck pass - Lefthook commit-msg -> commitlint pass - Started Studio locally at `http://127.0.0.1:5190/#project/undo-redo-sample`. - Used `agent-browser` to select a preview element in the Inspector and change `#hero-card` from `left: 220px` to `left: 260px`. - Refreshed Studio and verified Undo stayed enabled. - 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`. - Local screenshots and recordings are kept under `qa-artifacts/studio-undo-redo-2026-04-28/` and are intentionally not committed. - The scratch Studio project used for browser proof is local-only under `packages/studio/data/projects/undo-redo-sample/` and is intentionally not committed. - The PR intentionally excludes the earlier PRD/TDD planning notes under `docs/superpowers/`; those remain local-only per request. * 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`. - `bun run --cwd packages/studio test -- vite.thumbnail.test.ts src/utils/projectRouting.test.ts src/utils/frameCapture.test.ts` - `bun run --cwd packages/core test -- src/studio-api/routes/thumbnail.test.ts` - `bunx oxfmt --check .github/workflows/preview-regression.yml packages/studio/vite.thumbnail.ts packages/studio/vite.thumbnail.test.ts packages/studio/vite.config.ts packages/studio/src/utils/projectRouting.ts packages/studio/src/utils/projectRouting.test.ts packages/studio/src/utils/frameCapture.ts packages/studio/src/App.tsx packages/core/src/studio-api/routes/thumbnail.ts packages/core/src/studio-api/routes/thumbnail.test.ts` - `bunx oxlint .github/workflows/preview-regression.yml packages/studio/vite.thumbnail.ts packages/studio/vite.thumbnail.test.ts packages/studio/vite.config.ts packages/studio/src/utils/projectRouting.ts packages/studio/src/utils/projectRouting.test.ts packages/studio/src/utils/frameCapture.ts packages/studio/src/App.tsx packages/core/src/studio-api/routes/thumbnail.ts packages/core/src/studio-api/routes/thumbnail.test.ts` - `bun run --cwd packages/studio typecheck` - `bun run --cwd packages/core build:hyperframes-runtime` - `bun run --cwd packages/core typecheck` - `git diff --check` 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. * feat: persist studio manual edits via manifest * fix(studio): stabilize manual edit manifest rendering * fix(studio): allow master canvas layer selection * fix(studio): scale master edits in source coordinates * fix(studio): reapply manual edits during playback * fix(studio): keep rotation edit base stable * feat(studio): highlight hovered canvas target * fix(studio): drag hovered canvas targets immediately * fix(studio): rotate manual edits around center * fix(studio): keep rotate handle aligned while dragging * fix(studio): allow small rotation adjustments * fix(studio): match rotate handle size to resize handle * fix(studio): connect rotate handle line to selection * feat(studio): reset selected manual edits * fix(studio): route inspector geometry through manual edits * feat: add studio group repositioning * fix: preserve studio group selections * fix: seed additive studio selection groups * fix: select studio groups on pointerdown * fix: harden studio group overlay events * fix: address studio manual edit review feedback * fix: apply nested manual edits in drilled previews * fix: commit drag offsets from gesture math * fix: persist manual preview edits on refresh * fix: harden manual edit refresh apply * fix: share manual edit render runtime * chore: release v0.5.0-alpha.15 * feat(core): add studio animation preview APIs * feat(studio): add alpha editor layer inspector * chore: release v0.6.0-alpha.1 * feat(studio): enable inspector panels by default * fix(studio): keep motion panel opt-in * chore: release v0.6.0-alpha.2 * feat: auto-open timeline clip layers * feat: show composition loading in studio * feat: disable Studio timeline while composition loads * chore: ignore .claude directory * chore: release v0.6.0-alpha.3 * feat(studio): simplify inspector selection ux * fix(studio): keep notion preview playback moving * fix(studio): handle raster inspector clicks * fix(studio): stale selection, rotation control, design panel polish 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.

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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(studio): revert motion panel default to false Motion panel stays opt-in via env var per product direction. Only the Design panel is enabled by default. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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).

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.

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). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: release v0.6.0-alpha.5 * chore: release v0.6.0-alpha.6 * 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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: release v0.6.0-alpha.7 * fix(studio): restore text field handlers lost in rebase Restores handleDomAddTextField and handleDomRemoveTextField that were dropped when resolving App.tsx conflicts during the main→next rebase. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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. * chore: release v0.6.0-alpha.9 * feat(studio): consolidate keyboard shortcuts into single handler 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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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.

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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * 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.

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.

fix(core): preserve per-element preload ordering in render mode
The lazy media preloading refactor split bindMediaMetadataListeners into two loops: bind all listeners first, then preload all elements. This changed when metadata listeners fire relative to .load(), shifting timeline duration hydration and causing 3 transition frames to render at a slightly different state in the style-9-prod regression test. Move eager preload back inside the per-element binding loop so listener attachment and .load() happen in the same iteration, matching the original ordering. Lazy-mode demotion stays in a separate block after mediaPreloader.refresh() since it needs the full clip list. |

fix(core): skip media preloader activation in render mode
mediaPreloader.refresh() was called unconditionally, setting lazy=true for compositions with ≥6 clips even in render mode. player.seek then called preloadAroundTime() which evicted clips via src clearing, destroying buffered data needed for frame-accurate capture. Skip refresh() when __HF_EXPORT_RENDER_SEEK_CONFIG is set so isLazy() stays false and the preloader is completely inert during renders. |

fix(core): parent-frame proxy bypass, data-preload-eager opt-out, configurable threshold
- Player: _adoptIframeMedia now skips media with preload="metadata" or "none", preventing parent-frame proxies from bypassing the preloader. MutationObserver extended to watch preload attribute changes so proxies are created just-in-time when the preloader promotes a clip. - init.ts: lazy-mode demotion loop skips elements with data-preload-eager, letting power users keep specific clips eagerly buffered. - mediaPreloader: reads window.__HF_LAZY_PRELOAD_THRESHOLD as an override, falling back to the default 6. |

fix(core): add LRU eviction to media preloader, protect untimed media
Three root-cause fixes for the lazy media preloading feature: 1. Untimed media orphaned at preload="metadata": the else branch in bindMediaMetadataListeners demoted ALL media elements, but the mediaPreloader only manages timed clips (data-start). Untimed media (background audio, ambient loops) got stuck at metadata forever. Now only timed elements are demoted. 2. Monotonic promotion with no eviction: once promoted, clips stayed at preload="auto" forever. Scrubbing through the full timeline promoted everything, bringing back the OOM crash. Added LRU eviction with MAX_PROMOTED=5 — when clips leave the preload window, their src is cleared and load() called to release buffered data per MDN. On re-entry, the original src is restored. 3. Metadata preload without load(): setting preload="metadata" alone doesn't guarantee the metadata fetch in Chrome Lite mode or Firefox with media.preload.default=0. Now load() is called after demotion to ensure el.duration is populated for timeline computation. Also adds exact-boundary tests for LAZY_THRESHOLD=6 and eviction coverage (evict on scrub, src restoration, MAX_PROMOTED cap, load() called on eviction). |

feat(core): integrate media preloader into runtime and studio
Wire the MediaPreloadManager into init.ts: - Detect render mode via __HF_EXPORT_RENDER_SEEK_CONFIG (keeps eager preload) - Gate bindMediaMetadataListeners: lazy mode sets preload="metadata", eager mode keeps preload="auto" (unchanged for small compositions) - Advance preload window in the timeline poll tick loop - Call preloadAroundTime on seek for instant buffering at seek target Studio Player.tsx: hasUnloadedAssets now skips elements with preload!="auto" so deferred clips don't block the loading overlay. |

feat(core): lazy media preloading for heavy compositions
Compositions with many large video files (e.g., 6GB across 20 clips) crash the browser because the runtime eagerly sets preload="auto" + .load() on every media element at startup. All files buffer simultaneously, exhausting memory. Add a MediaPreloadManager that gates preloading based on playhead position: - Activates when a composition has ≥6 timed media elements - Only preloads clips within a 10-second lookahead window (or next 2 clips) - Far-away clips stay at preload="metadata" (resolves duration without downloading data) - Advances the window on each transport tick and immediately on seek - Render mode (window.__HF_EXPORT_RENDER_SEEK_CONFIG) keeps eager preload for deterministic frame capture - Small compositions (<6 clips) keep eager preload — no behavior change Studio's hasUnloadedAssets now skips elements with preload!="auto", so deferred clips don't block the loading overlay. |

refactor(core): tighten WebAudio rate fix per review
- Hoist duplicated test mock helpers (createMockAudioContext / setupTransport / mockBuffer / mockEl) from the two describe blocks to module scope. - Drop redundant math-derivation comments in schedulePlayback; the dedicated rate-aware tests are the canonical proof. - Tighten setRate JSDoc. - Add no-op guard in setRate when the new rate equals the current rate, so a duplicate set-playback-rate postMessage doesn't re-anchor or walk active sources for nothing. - Add a regression test for the no-op guard, and strengthen the clamp test to schedule at rate=2 first so the clamp-to-1 assertion is non-vacuous. |

fix(core): thread playback rate into WebAudio audio sources
WebAudioTransport scheduled AudioBufferSourceNodes with the implicit default playbackRate of 1, so non-1x transport rates desynced visuals from audio: GSAP timelines, the transport clock, and native <video> all sped up while WebAudio-routed <audio> clips kept playing at 1x. - schedulePlayback now accepts a rate, sets sourceNode.playbackRate, and scales the future-clip start delay by the rate (the in-progress buffer offset stays elapsed + mediaStart, which is rate-independent). - New setRate() updates active sources in place and rebases the getTime() reference frame so the audio-master clock stays continuous across mid-playback rate changes. - Runtime onSetPlaybackRate now forwards into webAudio.setRate, and player.play() schedules each clip with state.playbackRate.

fix(runtime): add setter to delegated __player properties
The property delegation on window.__player used Object.defineProperty with only a getter, causing "Cannot set property renderSeek which has only a getter" when Studio's motion-wrapping code tried to reassign __player.renderSeek with a wrapped version.

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

feat(runtime): swallow() helper replaces empty catches in inlined runtime
After hf#641 inlined the runtime IIFE into every bundle, lint tools
inspecting bundled output (including Abhay's c2v eval) started flagging
empty `catch {}` blocks across the runtime. The source had explanatory
comments inside, but esbuild's minifier strips them — the IIFE ships
~10 visible patterns of `}catch{}` and consumers' linters fire on each.
Each empty catch is intentional best-effort error swallowing —
postMessage to a parent frame that may not exist, `media.play()` /
`pause()` that throw under autoplay restrictions, timeline `seek()` on
a disposed timeline, anime.js / lottie feature detection on hosts that
don't load those libraries, etc. The right behaviour stays "tried,
didn't work, move on", but doing it visibly improves three things:
- lint clean: helper call is a real statement; no `no-empty` warnings
survive minification
- debuggable: flip `window.__hfDebug = true` in DevTools to see every
swallow site with `console.debug` (silent in prod by default)
- observable: studio / embeddings can install
`window.__hf.onSwallowed = handler` to collect runtime swallow
events without polluting the page console
Implementation: `packages/core/src/runtime/diagnostics.ts` exports
`swallow(label, err?)`. 41 catch sites across 12 runtime files
converted via mechanical pass (auto-generated `runtime.<module>.siteN`
labels — labels can be tightened site-by-site as a follow-up; the
shape of the change is what matters here).
Verification:
- core 674/674 (incl. 6 new diagnostics tests covering silent default,
__hfDebug logging, legacy __HYPERFRAMES_DEBUG flag, handler hook,
handler-throws-doesn't-recurse, both-active)
- typecheck clean
- format / lint clean
- runtime IIFE rebuilds successfully (`bun run build:hyperframes-runtime`)
Refs Abhay's c2v eval — bundler artefacts now lint-clean with the
runtime body inlined.
