Minecraft hot backup and consistency leases

Coordinate save writes while the game is running, review consistency modes and warnings, and verify Minecraft hot backups.

Active target

MineRewind 1.9.8 resolves a valid world and held session.lock, not only a level.dat lock. Manual backup, hotkeys and current_save selectors enter the same Host workflow. v3 has no old EnableHotBackup switch.

Coordination

The Host resolves Kind/readiness/consistency intent and calls IBackupConsistencyCapability. Active worlds coordinate KnotLink/mod handshake/WORLD_SAVED. A disposable snapshot source feeds the same enumeration/archive capture.

Success, cancellation and failure must release temporary data. v3 does not return replacement paths through OnBeforeBackupFolder or edit archives afterward.

Prefer and Require

With permitted rawWithWarnings, Prefer can degrade to SuccessWithWarnings plus specific coordination/snapshot diagnostics; it is not proof of game consistency. Require blocks unavailable handshake/save/stable source. Missing/invalid region providers must not silently broaden protection.

Request and acceptance

cmd=BACKUP;current_save=true;backup_mode=smart;from=panel;request_id=hot-001

Query capabilities and correlate final signals. Missing/multiple worlds produce diagnostics; accepted is not finished. Test online coordination, offline warnings, Require blocking, cancellation, cleanup and real archive restores.
