When no other peer is present, heartbeats, force-sync, and episode auto-sync
are now fully suppressed (previously the keepAlive heartbeat, force-sync, and
episode lobby were still broadcast to an empty room):
- keepAlive heartbeat gated on a live peer count
- force-sync is a no-op when solo (no pause-then-timeout freeze, no traffic)
- episode auto-sync skips the lobby entirely and just plays the next episode
The solo state is recomputed live from the current peer list on every event
(never cached), so the instant another peer joins syncing resumes. On that
solo->not-solo transition the background also requests an immediate heartbeat
from the content script so the newcomer sees the current position without
waiting for the next interval.

Room ID, password, and username were resurrected from synced storage on a
fresh install (sync survives an uninstall in the user's Google account), which
made the extension silently auto-connect to a dead room and appear permanently
connected. getSettings() and all settings reads (popup, content, audio-options,
applyAudioSettingsToTab) are now local-only, and legacy keys are actively
purged from sync on install/update/startup. Only onboardingComplete and
dismissedHints remain in sync.

Address client-side rate-limit edge cases that could trip the server's
per-socket event budget or per-IP connection limit:
- Pace the offline event-queue flush after (re)connect in batches
(10 per 3s) instead of one synchronous burst, so a reconnect after a
long outage no longer dumps the whole backlog and gets kicked.
- Wrap socket.send() in try/catch and re-queue on failure (race with a
server-side disconnect) instead of losing the event.
- Ping liveness: tolerate one missed PONG; only force a reconnect after
2 consecutive misses (~20s) instead of a single hard 5s timeout.
- Reconnect backoff: tune to ~8 attempts/60s (under the connection limit)
and add +/-20% jitter to de-synchronize reconnect herds.
All magic numbers extracted into named constants.

3-way merge of Kaia-Alenia's tab-manager refactor (PR #11) onto current
main (v2.4.3). Only the tab-related service-worker listeners move out of
background.js into extension/modules/tab-manager.js via initTabManager({...})
dependency injection; all other recent main changes are preserved untouched.
Behavior-preserving; listeners still register synchronously at top level.
The unrelated website/assets/NewLogoIcon_64.webp change from the PR was
excluded to keep main clean.

Switch the Ko-Fi support links to https://support.koalastuff.net across the
README badge, the extension footer (popup.html/template.html, label
"Support KoalaSync") and remove the now-unused KOFI_URL constant. Stop
generating/sending the anonymous uninstall token: initUninstallURL() now
registers the feedback URL without the `t` parameter or storage write.
CHANGELOG updated to match.
Also guard the client CMD_ACK path: only ACK a command sender that is still
a known peer in the room, so we don't emit ACKs to peers that already left
(which the server now drops as absent-peer ACKs anyway).

Move extractEpisodeId() and sameEpisode() to shared episode-utils.js.
background.js imports via ES module. content.js (IIFE) receives injected
copy via build-extension.js marker replacement, eliminating duplication.
- background.js: remove isConnecting=false at line 608 (was set before
WebSocket handshake completed, defeating the guard for the entire
CONNECTING phase). isConnecting is already properly reset in onclose,
onopen/40 handler, catch block, and socket guard path.
- background.js: restore isConnecting=false in forceDisconnect() so
subsequent connect() calls can proceed after intentional disconnect.
- popup.js: remove hardcoded applyConnectionStatus('disconnected') that
caused a guaranteed red flicker on every popup open. Status is now
set only by the async GET_STATUS response.
- Prevent concurrent connect() by removing isConnecting reset from
forceDisconnect(); the guard in connect() now reliably blocks
re-entry since no external caller can defeat it.
- Reset isConnecting at end of connect() so subsequent calls can
proceed without waiting for the async '40' handler.
- Clear connectIntent and cancel reconnect timer on server ERROR
when no currentRoom exists, preventing infinite reconnect loops
after failed join attempts (e.g. wrong password via invite link).
- Move connectIntent assignment after !roomId guard in
WEB_JOIN_REQUEST to avoid clobbering existing intent on invalid
input.
- Broadcast JOIN_STATUS failure to popup and bridge tabs when
WEB_JOIN_REQUEST receives an invalid room ID, so the website
join page receives feedback instead of hanging forever.
- Clear joinBtnTimeout on CONNECTION_STATUS connected/disconnected
to avoid stale timeout error messages in the popup.
After LEAVE_ROOM or idle-leave, reconnectAttempts was not reset.
GET_STATUS would return 'reconnecting' instead of 'disconnected',
showing wrong status in popup and leaving Retry button visible.
- Add connectIntent flag to gate all reconnect attempts
- Only auto-connect on startup if roomId exists in storage
- Close socket + stop reconnect after leaveRoom or idleLeave
- Preserve existing behavior 1:1 when actively in a room
- Guard force-sync state and peer list clearing during transient disconnects
- Guard WEB_JOIN_REQUEST against empty sanitized roomId
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.
- Fixed episode guard regex to support Sxx:Exx title format (Jellyfin/Emby)
and any non-alphanumeric separator between season and episode numbers
- Migrated username, roomId, password, serverUrl, useCustomServer from
chrome.storage.sync to chrome.storage.local for per-device isolation,
preventing automatic cross-device room joins with duplicate names
- Added one-time migration from sync to local for existing users
- Copy Logs button now generates full Markdown debug report (system, tab, connection, video, history, logs)
- Enhanced Dev tab with 20+ video state fields (network, dimensions, error, shadow DOM, platform detection)
- Platform auto-detection (YouTube, Netflix, Twitch, Prime Video, Disney+, Hulu, HBO, Vimeo, Dailymotion)
- 'No video found' diagnostic mode with hints
- Convert mockup from inline <span lang> to {{MOCK_*}} template vars (all 6 languages)
- New TwoPointZero branding: icons (16/32/48/96/128), favicons (PNG 16/32 + apple-touch + 192)
- Fix logo vertical centering via display:contents on picture wrappers
- Increase popup logo to 48px, website nav logo to 64px
- AVIF quality 70->80, speed 6->4, remove min 3KB threshold
- Add 32+96 icon sizes to manifest
- Remove amazon. from tab blacklist (unblocks Prime Video)
- Update TESTED_SERVICES.md: mark Prime Video as non-functional
- Update CONTRIBUTING.md with Copy Debug Report workflow
- Add currentServerUrl tracking: only disconnect/reconnect when server URL actually
changes, otherwise reuse existing connection and just switch rooms
- Add resolveServerUrl() helper for consistent URL resolution across handlers
- forceDisconnect() now resets currentServerUrl to null
- CONNECT and WEB_JOIN_REQUEST handlers: smart comparison before reconnecting
- Add generateRoomId(): human-readable 'ADJECTIVE-NOUN-Number' format (e.g. HAPPY-KOALA-16)
- Replace Math.random() room IDs with generateRoomId() in joinBtn and handleCreateRoom()
- Expand USERNAME_ADJECTIVES: +16 words (Turbo, Zen, Pixel, Cyber, Solar, etc.)
- Expand USERNAME_NOUNS: +12 words (Yeti, Goblin, Pirate, Ninja, Wizard, Storm, etc.)
- Add emoji mappings for all new words
- WEB_JOIN_REQUEST handler: forceDisconnect+connect instead of reusing old socket
(same bug as CONNECT: JOIN_ROOM was sent to official server instead of custom)
- joinBtn handler: generate random password when roomId is empty and password empty
(previously created rooms without passwords when using the advanced join button)
- Auto-copy invite link when creating room via joinBtn (consistent with Create Room button)
- Fix: CONNECT/RETRY_CONNECT always force-disconnect before reconnecting
(prevents JOIN_ROOM going to official server when custom is selected)
- Add forceDisconnect() helper: clears socket, eventQueue, episodeLobby,
expectedAcksCount, broadcast status, persists cleanup to storage
- Fix: save useCustomServer to storage on Join Room click (no race condition)
- Fix: trigger RETRY_CONNECT on server mode toggle and custom URL change
- Fix: show error when Custom selected but no URL entered (no silent fallback)
- Fix: button label changed to 'Join / Create Room' in all 6 locales
- Rewrite scheduleReconnect() for two-phase strategy:
Phase 1 (aggressive): 500ms-5s backoff, max 20 attempts or 5 minutes
Phase 2 (slow): retry every 5 minutes indefinitely, never give up
- Persist reconnectAttempts/reconnectStartTime/reconnectFailed to session storage
- Remove 'reconnect_failed' status; slow mode shows as 'reconnecting' with retry button
- Add scheduleReconnect() call on offline path to continue retry cycle
- Create shared/names.js as single source of truth for emoji maps, noun
lists, adjectives, and username generation (215 animal emoji entries)
- Remove duplicated inline lists from popup.js and background.js; both
now import getAvatarForName / generateUsername from shared/names.js
- Add names.js to the build script sync list so it stays DRY across
extension builds
- Fix missing cat emoji: CoolCat now correctly resolves to 🐱
- Sort emoji map keys by length at lookup time to prevent substring
false-matches (e.g. 'caterpillar' before 'cat')
- 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
