openai/gpt-chat-latest → B (3:2)

Side B makes a deeper architectural change by removing `EntityImported` events and the `EntityStore`, keeping Reddit content out of the event log, storing only ephemeral display data in the projection with TTL-based eviction, and updating replay/projection logic and tests accordingly. Side A adds a substantial invite system (invite minting, redemption, audit RPCs, CLI support, and tests), but it also introduces event types (`InviteMinted`/`InviteRedeemed`) that are not actually used while the implementation relies on in-memory invite state, making the design less cohesive than B's storage simplification.
