Adds application-level ping/pong between extension and relay server.
Extension sends PING every 15s, server echoes PONG. Round-trip time
displayed in Status tab (green/yellow/red color-coded).
Server also forwards PING with target peerId and routes PONG back,
enabling future peer-to-peer ping without server restart.
Extension already responds to incoming peer PINGs.
See CHANGELOG.md for details.
- Add renderEmpty() helper with icons and hints for peers/history/logs/rooms
- Implement onboarding tour (4 steps) with overlay, dots, skip/next
- Dev tab logs only poll when tab is visible (isDevTabVisible flag)
- Expand username generation from 12/12 to 30/30 adjective-noun pairs
- Update ROADMAP.md to remove implemented features
Adds a new toggleable feature that detects episode transitions via
mediaTitle mutation (loadeddata/MutationObserver), pauses the video,
and waits for all room peers to load the same episode before
executing a coordinated Force Sync play at 0:00.
Protocol:
- Add EPISODE_LOBBY and EPISODE_READY events to shared/constants.js
- Add EPISODE_LOBBY_TIMEOUT (60s) constant
- Relay both new events in server/index.js
Content Script (content.js):
- Layered detection: loadeddata + MutationObserver src-change + heartbeat
- Debounced onEpisodeTransition() sends signal ONLY; no eager pause
- PAUSE_FOR_LOBBY handler pauses only after background confirms feature enabled
- startLobbyPoll() polls title match without premature pause for non-initiators
- checkAndReportLobbyReady() pauses and sends EPISODE_READY_LOCAL on match
- CONTENT_BOOT recovery for re-injection after hard navigation
Background (background.js):
- Episode lobby state persisted in chrome.storage.session with recovery
- EPISODE_CHANGED: checks setting, creates lobby, sends PAUSE_FOR_LOBBY to tab
- EPISODE_LOBBY/READY server event handlers with dedup logic
- 60s timeout cancels lobby (Option B) with Chrome failure notification
- Peer departure handled: removes from readyPeers, re-checks completion
- executeEpisodeLobby() reuses existing Force Sync pipeline at targetTime 0.0
- Lobby cleared on LEAVE_ROOM; status exposed in GET_STATUS
Popup:
- Auto-Sync Next Episode toggle in Settings tab (default: off, opt-in)
- Episode Lobby status card in Sync tab with peer readiness display
- LOBBY_UPDATE message handler for real-time UI updates
Bumps APP_VERSION and manifest to 1.2.0
- Localized Chrome icon (removed Wikimedia dependency).
- Removed remaining Google Font CDN from extension popup.
- Updated AI_INIT.md with strict 'Zero-External-Requests' policy.
- Verified all website and extension assets are served locally.
- Integrated 'Koala-Bridge' for seamless web-to-extension communication.
- Implemented dedicated, minimalist invitation page (join.html).
- Added brute-force protection and RAM-cleanup to the relay server.
- Removed external fonts and trackers from the landing page (Privacy First).
- Unified header/footer design across all website pages.
- Added MIT License and comprehensive legal documentation (Impressum/Datenschutz).
