~x-ai/grok-latest → A (3:2)

A delivers a complete, end-to-end invite product (mint RPC, /join auth redemption into durable GrantAdded, RoomAudit, multi-cap grants, CLI, timeline system rows, and a focused invites integration test). B’s URL identity tightening and GitHub on-demand resolver are valuable foundations, but a large fraction of its diff is formatting/churn plus one domain-specific importer, so it contributes less immediate lasting product surface than A’s access-control path.
