+Connect to `localhost:25565` as `WindMagi`, which the harness configures as a level-4 operator using its deterministic offline-mode UUID. The committed `docker/test-ops.json` fixture replaces local operator state on every startup so the offline UUID remains deterministic.

 The first startup may take several minutes while the image downloads and Spigot is prepared. Override the 15-minute wait or local RCON password when needed:

+### US-010 offline operator identity corrected
+
+- Reproduced WindMagi's missing operator privileges and found that name-based image setup stored the online account UUID while offline-mode login assigned deterministic UUID `6a3b6e9f-1a2f-380c-8a75-7a7ca6392c0e`.
+- Replaced name-based setup with a synchronized, committed operator fixture containing the exact offline UUID; synchronization intentionally makes WindMagi the sole operator in this isolated test harness.
+- Removed the misleading post-start `op WindMagi` check and made startup verify the exact name and UUID in the generated `ops.json`.
+- Live restart verification passed: Spigot was healthy, RCON reported TreeFeller, `ops.json` contained only WindMagi at level 4 with the offline UUID, and the server remains available at `localhost:25565`.
+
 ### US-010 local Docker test server completed
 
 - Added a repository-local Docker Compose harness using `itzg/minecraft-server:java25` with Spigot 26.2, persistent ignored state, offline local testing, and loopback-only port binding.
