## Changelog
*   **0.11.4**: Fixed weekly readiness reset not triggering on Tuesdays — epoch was misaligned to Saturday boundaries instead of WoW's Tuesday reset schedule.
*   **0.11.3**: Session-Aware Sync: event-driven raid sync with RVR protocol (3-attempt repair + verified convergence), debounced SYNC_ACK (~60% message reduction), encounter/session-start convergence gates, timestamp-guarded delta merge, and debounced late-joiner push. Eliminates race conditions from premature lastUpdate bumps during boss kill tracking.
*   **0.11.2**: Fix sync lead election (wrong GetRaidRosterInfo field), EP/GP hash divergence after boss kills (lastUpdate propagation), Loot History cumulative GP reset across dates, and RCLC import re-run safety (void-without-create guard)
*   **0.11.1**: Fix readiness bar crash (NaN/inf) when readinessCap is zero in MyProgress, UISandbox, and Onboarding
*   **0.11.0**: Fix session breakage during raids: corrected startedAt/startTime field mismatch in V2 snapshot merge that allowed stale peer snapshots to delete active sessions. Added backward-compat alias in BuildSnapshot. Batched CalendarSignup EP awards to reduce sync storm. Fixed IsPlayerReachable O(n) timeout with 2s TTL cache. Fixed stale player selection persistence after session end. Added EP_Import module for deterministic ledger-based EP re-import.
*   **0.10.35**: Added /cb support command with Payload Inspector UI — generates a diagnostic report with addon status, sync state, config, and event trace log for troubleshooting. Officers can remotely request reports from other players via secure RPC.
*   **0.10.34**: Fix non-officer snapshot data acceptance (selection, config, signupAwards now officer-guarded); fix self-exclusion in HandleSnapshot/HandleFetch using robust short-name matching
*   **0.10.33**: Fix RCLC import pipeline (date filter, timestamps, dedup), add dry-run simulation command; hide voided transactions in History tab; targeted sync PUSH to divergent peer only; scope Sync Health display to active online peers
*   **0.10.32**: Harden format strings against Lua 5.1 integer overflow on corrupted millisecond timestamps. Add RCLC Import module for GP history rebuild from RCLootCouncil data.
*   **0.10.31**: Batch EPGP broadcast reduces boss kill sync from 120-180s to ≤5s. Adds convergence tracking, Sync Leader exclusive boss kill processing, and PR sort tiebreaker in RCLC voting frame.
*   **0.10.30**: History tab sync for non-ML officers (real-time BROADCAST_TX); /cb synchistory for retroactive catch-up; 3-tier sync leader election (WoW raid leader wins)
*   **0.10.29**: Guild Roster Sync Dashboard: combat guard on guild scan and heartbeat UI refresh; LWW sentinel for auto-discovered players; semver version comparison; cached online-member lookup; DRY sync health helper; correct no_addon (red) / unknown (gray) colors; stale addonStatus pruning; config hash convergence fix (sync.lastUpdate excluded, fixes 25/25 to 1/25 every-5-min bounce)
*   **0.10.28**: Fixed 'You are not in a raid group' spam when an officer or raider is in an LFR group — the heartbeat and sync broadcasts now correctly skip the RAID channel in instance/matchmade groups.
*   **0.10.27**: Fix season reset double-fire and single-person standings on concurrent officer login. Prevent duplicate EP/GP wipe when multiple officers log in after a new season starts.
*   **0.10.26**: Prep check redesign with proportional EP scoring, per-section config LWW sync, realm name normalization, database hardening, and session lifecycle fixes.
*   **0.10.24**: Fix officer sync divergence: dynamic config hash covers all settings automatically, config merge uses LWW timestamps, auto-discovery no longer pollutes roster timestamps, purge/block zombie cleanup on snapshot receive.
*   **0.10.23**: Player Management Overhaul: new /cb block, /cb unblock, /cb blockedlist commands; purge is now a soft reset; auto-discover group members as Pending; Standings rank filters and Hide Non-Guildies restored; sync field whitelist drops junk data; UTF-8 player name fix; non-guild players display '--' rank instead of 'Unknown(R99)'.
*   **0.10.22**: Added calendar sign-up EP, custom EP templates, Farm/Prog boss EP split, collectible item GP (toys, pets, mounts), and duplicate slot GP multiplier. Fixed sync loop causes including officer-to-officer hash divergence, redundant dual-channel raid broadcasts (PR26), and synccheck self-echo.
*   **0.10.21**: Fix permanent sync divergence from ghost Pending records and eliminate thundering herd during raid sync (Options A/B/E).
*   **0.10.20**: Officer detection refactored to use guild permission flags (GuildControlGetRankFlags) instead of rank-name matching. Added per-tier RCLC GP modifiers, standings multi-select with bulk actions and context menu, configurable tooltip mode (always/raid/never), M+ EP formula v1.2 with min-level gate and per-tier guild bonuses, and session pre-flight player validation. Config schema reorganized into Admin, EP Awards, and GP Modifiers categories.
*   **0.10.19**: Accept M+ Readiness EP broadcasts from raiders (fixes stranded EP) and add bidirectional officer-to-officer snapshot exchange on mismatch (fixes post-season-reset sync stalls).
*   **0.10.18**: Rate-limit heartbeat echoes to once per peer per 90 seconds and add receive-side dedup (5s window) to eliminate duplicate HB processing from stacked senders.
*   **0.10.17**: Fix raider LWW merge to detect and override auto-created Pending stubs that block officer data, while preserving real EP/GP from multi-officer scenarios. Improves merge debug logging with stub override tracing.
*   **0.10.16**: Fix persistent roster hash divergence between officers and raiders by making raider-side reconciliation adopt the officer's player set as authoritative. Add /cb debughash diagnostic command for cross-client hash comparison. Fix heartbeat retry backoff to auto-reset after 5 minutes instead of permanently suppressing sync attempts.
*   **0.10.15**: Fixed V2 sync loop and whisper storm: Resolved cross-realm reachability check bug in SendV2Message preventing ghost player cleanup. Enhanced IsOfficer fallback to use cached guild ranks, preventing officers from misidentifying each other. Added 15-second cooldown to HandleHeartbeat to prevent rapid FETCH retry suppression during echo storms.
*   **0.10.14**: V2 Persistent Session Sync: Session state is now a first-class V2 sync citizen with instant propagation via SyncToRaid(). Session ID included in roster hash for automatic divergence detection. Fixed HandleSessionEnd destructive wipe and HandleSnapshot nil session propagation. Added startedBy field to session schema. Updated Interface version to 120001 (Midnight pre-patch). Dev deploy now uses incremental _devN build numbering.
*   **0.10.13**: V2 Persistent Session Sync: Session state is now a first-class V2 sync citizen with instant propagation
*   **0.10.12**: Fixed season reset status reversion: raiders stuck in Awaiting Officer Approval after epoch upgrade due to phantom Pending record creation race condition. Removed premature RefreshAllUI() from HandleEpochMismatch. Added post-merge self-correction in V2 HandleSnapshot.
*   **0.10.11**: Fixed stale data resurrection after season reset: RPC dispatch rejects messages from senders with stale epochs. Added zombie session guard in EndSession - sessions older than 12 hours are discarded without awarding EP. Added epoch checks to HandleEPGPUpdate and HandleEPGPForward.
*   **0.10.10**: Fixed stale data resurrection after season reset: RPC dispatch now rejects all messages from senders with stale epochs (blanket protection). Added zombie session guard in EndSession — sessions older than 12 hours are discarded without awarding EP. Added epoch checks to HandleEPGPUpdate and HandleEPGPForward (defense-in-depth).
*   **0.10.9**: Sync payload integrity hardening: post-merge hash verification in HandleSnapshot detects LWW races and partial delivery, triggering automatic re-fetch on mismatch. Added SNAPSHOT_ACK RPC so officers receive convergence confirmation from receivers.
*   **0.10.8**: Migrated M+ communications to V2 transport with raid suppression gate. Fixed My Progress rank to respect Standings visibility settings.
*   **0.10.7**: Fixed V2 reset RPC key mismatch (RESET vs FACTORY_RESET) that silently dropped reset broadcasts. Added targeted WHISPER snapshot propagation for immediate reset delivery to online guild members. Fixed epoch upgrade data loss for raiders by auto-fetching officer data after epoch acceptance. Filtered Officer tab Player dropdown by Standings Visibility ranks.
*   **0.10.6**: Fixed V2 epoch propagation failure and standings reset data reversion. HandleEpochMismatch() replaces flat epoch rejection in V2 handlers, enabling proper epoch upgrades from officers. standingsreset now increments epoch to prevent stale data resurrection. Shared ResetStandings() core for both reset commands. Expanded factoryreset wipe scope.
*   **0.10.5**: Added /cb standingsreset YES officer command: zeroes EP, resets GP to base, and clears attendance for all players without incrementing epoch. Migrated /cb synccheck to V1 transport for reliable peer responses. Fixed totalBossKills sync guard to accept officer values unconditionally.
*   **0.10.4**: Bugfix: Added nil checks to IsItemToken function to prevent Lua errors when hovering over world content items without GP values.
*   **0.10.3**: Hotfix: Fixed nil target crash in SendFetch when RequestSync broadcasts to channel instead of specific peer.

## Officer Companion (Cloud Sync)

> [!IMPORTANT]
> **This section is for OFFICERS ONLY.** Regular guild members do not need any external tools.

For officers who want to sync EPGP data across multiple computers or create cloud backups, a separate **desktop companion app** is available.

### What It Does

- Watches your WoW SavedVariables for changes
- Uploads snapshots to your guild's private Supabase cloud storage
- Runs in system tray (menu bar on macOS)

### Security Model

- **Each officer has their own unique API key** - keys are NOT shared between officers
- **Config is stored locally** on each officer's machine (`~/.config/cerebro/config.json` on macOS)
- **Nothing is bundled** - downloading the app gives you a fresh setup wizard
- **Guild Master controls access** - only the GM can generate API keys for officers

### Getting Started

1. Your GM will provide: Supabase URL, Guild ID, and your personal API key
2. Download the app from [Releases](https://github.com/Shezzannn/Cerebro/releases)
3. Run the setup wizard and enter your credentials
4. The app runs in the background and syncs automatically

See [`docs/HELPER_APP.md`](docs/HELPER_APP.md) for full documentation.
