#031

Purpose

To finalize core system reliability before wider onboarding, focusing on match integrity validation, infrastructure stability under sustained load, and preparing Tapzi for controlled user growth without compromising fairness or performance.

Key Highlights

🧠 Match Integrity Validation Layer Strengthened

• Additional verification checkpoints added between match completion and settlement.
• Backend now cross-validates:
  • replay hash consistency
  • move sequence completeness
  • signature timestamps
• Prevents edge-case mismatches where valid matches could previously fail settlement under rare conditions.

📡 Real-Time Match State Monitoring Improvements

• Internal monitoring now tracks live match states with finer granularity:
  • active
  • reconnecting
  • stalled
  • completed

• Helps identify problematic matches earlier instead of post-failure detection.

🧱 Backend Queue Stabilization (Settlement & Events)

• Settlement queues refined to reduce processing drift during high concurrency.
• Event ordering improved to ensure correct sequence between:
  match end → verification → payout trigger.
• Reduces rare out-of-order execution risks observed in earlier tests.

🌐 Beta Access Control Tightened

• Beta access remains live at platform level (https://www.tapzi.io/game), but entry throttling introduced.
• Controlled onboarding batches ensure:
  • system stability
  • manageable support load
  • accurate feedback collection

Why It Matters

• Reinforces Tapzi’s core promise: skill-based outcomes must always be verifiable and fair.
• Long-duration stability testing is critical before scaling real users and real stakes.
• Improved monitoring reduces silent failures and increases operational visibility.
• Controlled growth ensures the platform evolves safely without exposing early-stage weaknesses.

Open Issues

• Rare delay observed in settlement confirmation under extended reconnect scenarios.
• Monitoring dashboard still internal-only; no user-facing match status visibility yet.
• Long-session memory optimization required for multi-hour continuous play environments.

Fixed

• Edge-case mismatch between replay hash and final board state resolved.
• Queue backlog issue from #029–#030 testing cycles stabilized.
• Incorrect match state transition (stalled → completed) under reconnect loops fixed.

Next Steps

• Introduce user-visible match status indicators (pending, verifying, settled).
• Further optimize long-duration memory handling in game engine service.
• Expand beta onboarding in phased cohorts with telemetry-backed thresholds.
• Begin early design of multi-game support architecture beyond Chess (without deployment yet).
