Side B ships a fully wired GitHub OAuth/session/pseudonym system (auth module, event handling in projection_apply.rs, cookie sessions, gating votes) backed by unit and browser-integration tests, plus a clean extraction of the durable crate to its own repo. Side A's invite feature works for the basic mint/redeem/audit path but leaves substantial dead code: the new events.rs InviteMinted/InviteRedeemed variants and reducer ActiveInviteState/RoomTimelineEntry logic are never produced by any code path, and the entire new server/src/timeline.rs (merge_thread_rows, System items) is unreferenced, indicating incomplete integration despite the large diff.
