- Change offscreen.ts from single recording variable to Map<tabId, RecordingState>
- Update all recording message handlers to route by tabId
- Track sessionId in relay server for proper recording lookup when stopping
- All recording operations now consistently require tabId
- Add getChromeRestartCommand() with --allowlisted-extension-id and --auto-accept-this-tab-capture flags
- Move EXTENSION_IDS to utils.ts for cleaner imports
- Add sessionId support for multi-tab recording
- Add helpful error message when activeTab permission is missing
- Add null check for empty extension result
- Document offscreen recording flow with ASCII diagram
- Use chrome.tabCapture.getMediaStreamId() from service worker
- Pass stream ID to offscreen document for MediaRecorder
- Recording survives page navigation (unlike getDisplayMedia)
- Requires user to click extension icon first (activeTab permission)
- Add esbuild to build offscreen.ts separately
- Update prompt docs with recording instructions
Work in progress for navigation-safe screen recording.
Implemented:
- tabCapture permission in manifest
- Recording handlers in extension background.ts
- Recording endpoints in relay server
- Binary WebSocket streaming for video chunks
- Protocol types for recording messages
- Executor integration
Needs:
- Offscreen document implementation (tabCapture not available in service workers)
- Connect background.ts to offscreen document via messages
- Update manifest for offscreen document
The offscreen.ts/html files are scaffolding for this next step.
