  "gameId": "GAME_01_BOARD",
  "turnIndex": 4,

Proposed reference architecture illustrating how four heterogeneous game loops can emit a standardized envelope for shared matchmaking, anti-cheat validation, and wallet balance settlements.

Pillar 01

Proposed Session Envelope

Reference JSON schema pattern standardizing session tokens, match IDs, and score payloads.

Pillar 02

Lifecycle Transition States

Proposed state transitions (Init, Ready, Active, Validate, Finalize) across casual games.

Pillar 03

Decoupled Engine Contracts

Architectural isolation allowing new game loops to connect to core platform services.
