Tournament & Matchmaking Engine

A deterministic 7-stage state machine governing tournament configuration, player queue clustering, entry fee deductions, and bracket progression across casual skill competitions.

7-Stage State Machine Lifecycle

Stage 01: Created

Instantiation & rules schema registration with Redis channel allocation.

Stage 02: Open

Registration queue visible in player lobbies; entry reservations accepted.

Stage 03: Entries Locked

Capacity boundary reached; roster sealed and queue closed.

Stage 04: Matched

Rating band cluster formed; synchronized challenge seeds emitted.

Stage 05: Playing

Live game sessions active under WebSocket event monitors and turn timers.

Stage 06: Validation

Score payloads, move histories, and timestamps validated on server.

Stage 07: Finalized

Prizes committed to Winning Balances via transactional database updates.

Queue Coordination Rationale:A Redis-backed queue coordination design ensures player entries are deduplicated across simultaneous tournament queues with instant refund handling if a match queue aborts.
