State Transition SpecState Code: OPEN_FOR_ENTRY
02. OPEN_FOR_ENTRY
Accepts player registrations, executes entry fee balance deduction, and queues entries.
Transition Trigger
Start timestamp reached & capacity unfulfilled
Allowed Next Transitions
→ MATCHMAKING_ACTIVE→ CANCELLED
Pillar 01
7 Deterministic Stages
Created -> Open -> Matchmaking -> In-Progress -> Validating -> Settling -> Finalized.
Pillar 02
Immutable State Triggers
State advancements driven by verified timestamps, capacity fulfillment, or clock expiry.
Pillar 03
Coordinated Room States
Transient room clusters synchronized via Redis memory state machine.
State Machine Determinism & Lock Guarantees
- Atomic state transition locks in Redis and MySQL
- Guaranteed rollback and entry refund logic on aborted matches
- Audit trail logging for every stage transition event
