init() called updatePeerList() directly but never set lastKnownPeers.
On the first PEER_UPDATE message (heartbeat, play/pause, any state
change), detectPeerChanges() saw lastKnownPeers=[] and treated ALL
peers including self as newly joined — triggering 'name joined the room'
toast on every action while the popup was open.
- FORCE_SYNC_TIMEOUT in shared/constants.js was 5000 but all code uses
8500ms. Update constant to 8500 and reference it in background.js
instead of hardcoded values (4 occurrences)
- Add errorToken counter in popup showError() so stale 5s timeout
doesn't clear styling of a newer error that arrived in between
- Fix EVENT_ACK handler indentation in server/index.js to match
surrounding socket.on handlers
- Add 10s timeout to ensureState() so extension doesn't hang forever if
chrome.storage.session.get() never calls back (storage API failure)
- Skip emit(LEAVE_ROOM) in leaveOldRoomIfSwitching when socket is down;
server already cleaned up via disconnect handler, avoid queued no-op
- Persist cleared peers to storage in socket.onclose to prevent stale
peer list restoration on service worker restart
- Store and clean up forceSyncReset setTimeout in popup unload handler
and when force_sync_execute completes
- Store real client IP from x-forwarded-for on socket for use in JOIN_ROOM
auth rate limiting (was using proxy IP, breaking brute-force protection)
- Remove clearEpisodeLobbyState() from socket.onclose to preserve lobby
across brief disconnects; ensureState() recovers lobby + timeout on reconnect
- Lobby is still properly cleared on intentional LEAVE_ROOM and room switch
- 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
- popup.js: guard peers/state.acks in updateLastActionUI()
- popup.js: guard state.duration in refreshDebugInfo()
- popup.js: guard elements.lobbyPeerStatus in updateLobbyUI()
- background.js: use Array.isArray() for currentRoom.peers.length checks
- CI release workflow now extracts version from tag (v1.4.0 → 1.4.0)
and injects it into manifest.base.json, shared/constants.js, and
package.json before building — the tag is the single source of truth
- Build script now copies README.md alongside constants.js and
blacklist.js from /shared → /extension/shared/ (full mirror)
- .gitignore updated: extension/shared/ is fully generated by build
- AI_INIT.md: simplified release workflow, fixed Chrome-only reference
Server Security (S-1 through S-8):

- S-5: Restrict room IDs to [a-zA-Z0-9-] only
- S-7: Add eventCounts periodic cleanup alongside connectionCounts
- S-8: Guard version parsing against NaN bypass
