Enable an existing AI difficulty for a human seat through admin controls without granting private access or advancing paused play. Preserve custody, credentials, takeback and separate paced resume. Bind atomic writes and outgoing-grant revocation to live authority, room/pause versions and active seat access with durable exact receipts.
Validation: types/lint, 5408 offline tests, build and 52 HTTP tests passed on source fingerprint 2157de0f4bb0b74d9760d52102601c52344cf674dee8ccd1d559f0a246a1d4ff; 22 authenticated admin HTTP groups, independent SQL/privacy/UI review, desktop/mobile and refresh checks. All 2098 baseline rooms and 4455 seats preserved. Migration 0015 is additive. Positive production admin QA awaits authorized access; full admin/rules scope remains unfinished.
Preserve room JSON, seats, credentials and messages while removed rooms deny ordinary reads and writes. Add deliberate room-scoped controls, removed-directory filters, persistent player notices and live-authorized atomic version/revision audit receipts. Retain uncertain room/seat requests and hidden recovery drafts through removal; restore the prior pause/join settings without reviving revoked credentials.
Fix AI readiness after a joining human or human faction change so real lobby starts remain legal.
Verified types, lint, 5314 offline tests, 52 HTTP tests and build. Fourteen authenticated HTTP groups and independent privacy/persistence review passed. Desktop/mobile browser QA confirmed a saved removal after a lost response and refresh, one audit on exact retry, persistent notices and recovery draft continuity. All 1,945 baseline rooms, 4,121 seats and related records preserved. Positive authenticated production admin acceptance remains pending authorized QA operator access; full admin and rules gates remain open.
