### Purpose

To lay the groundwork for Tapzi’s tournament automation system while stabilizing backend infrastructure and preparing basic integrations for future community and operational tooling.

***

### Key Highlights

* **Automated Tournament Scheduling Engine (Prototype)**\
  Built initial backend logic to auto-schedule rolling tournaments with dynamic time slots based on player volume and rule presets.
* **Reschedule/Cancellation Controller (Admin Only)**\
  Introduced backend hooks to allow rollback of scheduled events, with token refund logic attached to cancelled tournaments.
* **Start-Time & End-Time Enforcement**\
  Implemented logic to enforce both game start windows and match duration caps, preventing tournaments from hanging indefinitely.
* **Discord Bot Stub for Notifications**\
  Drafted early webhook structure for pushing tournament notifications to Discord (match status, start reminders, results).
* **Simulated Load Testing (Database Tier)**\
  Conducted database concurrency stress tests using synthetic match/tournament creation to assess indexing and connection pooling under pressure.
* **Expanded Lifecycle Logging (Match + Tournament)**\
  Added structured logging for full tournament lifecycle (created → open → active → completed → closed), as well as real-time tracking of game state transitions.

***

### Why It Matters

* Ensures future scalability by automating tournament operations.
* Reduces manual overhead, allowing the core team to focus on feature development.
* Strengthens back-office observability, enabling better visibility into system behavior under real usage.
* Begins social infrastructure with Discord alert capability, pre-aligning with community growth plans.

***

### Open Issues

* **Event Overlap Logic Undefined:** Multiple tournaments scheduled in overlapping time blocks can lead to participant conflicts.
* **Race Conditions in Auto-Start:** In rare cases, tournaments receive duplicate start signals from conflicting schedulers.
* **Discord Webhook Drops:** Message loss observed when sending high-frequency alerts under load; needs retry/backoff.
* **User-Facing Error Handling Lacking:** Errors in scheduling not currently exposed to the UI layer, leading to silent failures.

***

### Fixed

* **Participant Deduplication:** Eliminated bug where users could enroll multiple times in the same event due to session desync.
* **Consistent Analytics Trigger:** All game-end paths now properly fire analytics updates, ensuring complete match telemetry.

***

### Next Steps

* Implement user-friendly scheduling feedback (e.g., countdowns, slot errors, success states).
* Develop attendee email notifications for event start reminders and result summaries.
* Begin building Google Calendar export feature (ICS files for personal schedule syncing).
* Extend backend logic to handle overlapping event resolution intelligently.
