- tournaments.php: exclude cancelled tournaments (neq.cancelled filter),
  hide completed tournaments older than 3 days
- hub.js: treat 'draft' status same as 'registration' — show register
  button, green status pill, include in "registration open" filter
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- tournaments.php: remove non-existent 'ends_at' column from select
  (caused PostgREST error → empty tournaments list)
- i18n.js: add all missing tournament hub keys (my_tournaments,
  no_my_tournaments, format_*, players_label, etc.) + common keys
  (all, retry, failed, coins, play, minutes_abbr)

The client sends `after: lastTime` to fetch only new messages since the
last poll. Server now handles this with `created_at gt.{after}` filter.

  daily_claims, challenges, achievements, group_members)

Phase 1 (Chess Multiplayer Bulletproof):
- net.js: check content-type before JSON parse, clear error on HTML responses
- modal.js: stack-based resolve — stacked modals no longer hang
- match-session.js: fix null dereference after destroy, remove listener on cleanup
- match-session.js: only fire onConnectionRestored after actual disconnect
- lobby.js: prevent duplicate startGame calls with gameStarted flag
- lobby.js: add pollInFlight guard, clear timeouts on unmount
- lobby.js: derive color from match data when undefined (friend invite fix)
- scene.js: queue navigation during transition instead of dropping it

Phase 5 (Core UX):
- table.js: hide "My Games" button for non-chess games (no history scenes)
- queue.js: add polling overlap guard
- profile/view.js: show "Unrated" for new players instead of 1200
- i18n: add profile.unrated key (ar/en)

Updated tokens.css with aligned color values and added missing tokens
(bg-panel, bg-inset, bg-dark, gold-dark, purple-light, violet, green,
green-light, amber, red-light, red-soft, text-dim, text-light, info).

Updated theme.js applyColors map to support all new tokens via admin
branding panel.

Converted ~85% of all inline hex colors across 50+ JS files to use
var(--token) references. Remaining ~160 are canvas colors (which can't
use CSS vars) and unmapped game-specific colors.

27 files converted to use the emoji(slot, fallback, size) function from
core/theme.js, enabling full emoji customization via the admin branding

rewards, org, and tournaments.

Replace hardcoded Arabic in tournament-arena.js (7 strings),
tournament-detail.js (10 strings), tournament-live.js (8 strings).

All UI text across 57 files now goes through the i18n system (core/i18n.js).
Added ~120 new translation keys covering: auth, daily rewards, challenges,
ranks, shop, groups, tournaments, puzzles, orgs, emotes, and backgammon
doubling. Both ar and en dictionaries are complete and in sync.

Data strings (country names, FIDE titles, variant names, puzzle themes)
are intentionally left as-is — they use name/nameEn data pattern.

Phase 2.4: multiplayer.php now routes to correct table for all games
(chess→matches, domino→domino_matches, backgammon→backgammon_matches,
ludo→ludo_matches). Validates game_key against allowed list.

Phase 4.3: handleServerState in backgammon only copies specific fields
(state, dice, turn, gameOver) instead of Object.assign which clobbered
local methods and properties.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Phase 1.13: add unmountGame export for chess — stops clock, destroys board,
nulls gameState on scene exit.

Phase 5.1: notification items now navigate to relevant section on click
(friends, play, tournaments, achievements based on type).

Phase 6.6: remove remaining stopDisconnectWatch calls from domino/ludo
since disconnect detection is now fully handled by match-session.js.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Phase 7.1: add 30+ missing i18n keys for queue timeout, game states,
achievements, and chat. Replace hardcoded Arabic in chess game scene
with t() calls.

Phase 7.3: replace hardcoded hex colors in chess HUD and draw dialog
with CSS variables (--text-primary, --bg-surface, --success, --error).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Phase 1.6: add pollInFlight guard to match-session.js so overlapping polls
are skipped when server is slow.

Phase 2.5: room code generation retries up to 5 times on collision.

Phase 2.6: join_room uses service key, checks if room is full, prevents
double-join, and auto-starts when player count is met.

Phase 3.1: dealAndSyncToServer retries on failure with toast notification.

Phase 3.3: drawFromBoneyard syncs once after all tiles drawn instead of
firing N parallel requests.

Phase 3.6: check-invites uses PostgREST cs filter on JSONB players array
instead of scanning all waiting matches.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Phase 4: getPipCount now accepts variant param (fixes wrong pip count for
thirtyone variant), backgammon quit button shows confirmation dialog in
live mode.

Phase 3: syncPassToServer no longer pre-increments moveCount before network
success, winners array guards against empty state.players.

Phase 2: ludo bot "thinking" indicator uses dedicated .pp-status span
instead of clobbering the player name.

Phase 6: chat.php unread/recent queries batched into single DB calls
instead of N+1 per friendship.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Phase 5: queue 60s timeout with retry prompt, match history accepts game_key,
spectate routes to correct game scene, shop shows "owned" indicator, profile
shows dash instead of 1200 for unrated players.

Phase 6: remove duplicate disconnectWatch calls (use match-session only),
fix auth.php double token verification with requireAuthUser(), cascade
delete related data on account deletion.

Phase 1: fix opponentRating using actual rating in live mode instead of
botElos lookup.

Fix achievements recursive mount — update in-place instead of re-calling
mountAchievements.

SSHed into Supabase DB and compared all table schemas, RLS policies,
RPCs, enums, indexes, and reward_config rows against what the code
expects. Found 21 mismatches including: service key bypassing RLS
(making RLS useless), missing indexes, missing reward rows,
handleDraw destroying game_state, and complete_match trusting
client-provided winners array.

Root cause: draw offers stored in game_state were lost when a
concurrent move write did read→merge→write (non-atomic). Now uses
PostgreSQL jsonb || operator via merge_game_state() RPC for atomic
merges.

Also adds:
- mp_log table for server-side multiplayer event logging
- Frontend sessionStorage logging (sessionStorage.mp_log) for
  debugging draw offers, moves, and poll events
- Logging on match_created, move, resign, draw_accepted, game_state_merge

Screenshots confirm: moves sync to opponent board, resign shows
victory screen. Both directions verified via Puppeteer + API.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The `matches` table has no `last_activity` or `ended_at` columns.
PostgREST rejects the entire PATCH when ANY column doesn't exist,
causing every move update and resignation to silently fail.

- Remove `last_activity` from handleGameMove (column doesn't exist)
- Change `ended_at` to `completed_at` in handleResign, handleDraw,
  handleComplete (correct column name per DB schema)

This was the root cause of zero sync in multiplayer chess.
