Purpose
To improve synchronization for players accessing Tapzi across multiple devices, strengthen achievement validation for tournament and fair-play activity, and continue reducing inconsistencies between match history, player stats, and progression records.

Key Highlights

🔄 Multi-Device Session Synchronization Updates
Session refresh logic refined to prioritize the latest backend-confirmed player state when multiple devices are active.
Additional timestamp checks introduced to reduce older device sessions overwriting recently updated dashboard data.
Match-history refresh behavior improved when players reconnect or switch devices after completing a match.

🏅 Achievement Validation Coverage Expanded
Achievement validation rules extended for selected tournament participation and fair-play conditions.
Additional checks introduced to confirm match completion status before tournament-related achievements are processed.
New achievement categories remain restricted to internal validation while edge-case behavior is reviewed.

📊 Match History & Progression Reconciliation
Reconciliation flow updated to compare match history, aggregated stats, and achievement state before completing progression updates.
Improved handling of delayed match records arriving after dashboard statistics have already refreshed.
Additional mismatch logs added to help identify which stage caused an incomplete player update.

⚙️ Queue Processing & Monitoring Refinements
Queue retry intervals adjusted for reconnect-heavy and multi-device activity scenarios.
Internal monitoring now separates duplicate-event retries from delayed-event recovery attempts.
Grafana panels expanded to track session conflicts, progression mismatches, and delayed achievement processing.

Why It Matters
Reliable multi-device synchronization prevents outdated sessions from changing confirmed player progress.
Stronger achievement validation protects the accuracy of tournament and fair-play recognition.
Improved reconciliation between match history, stats, and achievements strengthens confidence in player profiles and progression data.
Clearer monitoring helps the development team identify synchronization failures without increasing operational complexity.

Open Issues
Rapid switching between devices can still cause temporary dashboard refresh delays.
Tournament achievement processing may be delayed when final match confirmation arrives late.
Some reconnect-heavy sessions continue to generate unnecessary queue retries.
Historical progression mismatches still require limited manual review.

Fixed
Reduced cases where an older device session replaced recently updated player statistics.
Resolved an issue where selected tournament participation records were counted before match confirmation.
Improved mismatch logging for delayed match-history and achievement updates.

Next Steps
Continue tuning session conflict resolution for players using multiple active devices.
Refine tournament and fair-play achievement validation across timeout and reconnect scenarios.
Reduce unnecessary queue retries generated during session recovery.
Expand automated reconciliation checks for older progression records.

Development Status:
Development remains focused on synchronization reliability, achievement accuracy, and controlled backend stabilization across active player sessions.
