~x-ai/grok-latest → B (2:1)

B removes EntityImported/EntityStore entirely and confines Reddit payloads to TTL-evicted projection caches while logging only NodeEnsured structure, a lasting data-model and compliance fix that simplifies journal, projection_apply, storage schema, and rebuild paths. A adds a useful invite/audit surface (RPC mint, /join redemption, multi-cap grants, CLI, tests) but is mostly additive feature surface with in-memory invites and partial event types rather than a foundational redesign.
