# Local Fleet Status and Drift
`mosaic fleet status [name]`, `verify`, and `doctor` are observational roster-v2 commands. They emit one JSON result and do not write projections, change desired state, start services, stop services, restart services, or mutate tmux.
mosaic fleet status [<name>], `verify`, and `doctor` are observational roster-v2 commands. They emit one JSON result and do not write projections, mutate desired state, operate lifecycle, or change tmux.
The report distinguishes:
## State dimensions
- `missing-session`: an enabled agent desired `running` has no exact roster-named tmux session.
- `unexpected-session`: a desired-`stopped` agent still has its exact session.
- `disabled-running`: a disabled roster agent has its exact session.
- `unmanagedSessions`: sessions on the configured named socket that are neither the exact holder nor an exact roster agent.
- `holder`: `owned`, `missing`, or `ownership-mismatch` after exact holder, private install identity, and complete global tmux environment validation.
- **Desired:** roster membership, generation, enabled flag, and persisted running/stopped target.
- **Managed/derived:** generated environment and expected exact service/session topology.
- **Observed by current roster-v2 commands:** systemd active state, tmux presence, exact holder ownership, and unmanaged sessions.
`doctor` and `status` classify rather than adopt, destroy, or repair unmanaged state. `verify` is observational too, but exits non-zero if ownership cannot be proven, unmanaged sessions exist, or drift is present. Reconciliation fails closed under those conditions and never kills or adopts an unmanaged session.
Implemented drift classifications include:
- `missing-session`: enabled/desired-running agent lacks its exact session;
- `unexpected-session`: desired-stopped agent has its exact session;
- `disabled-running`: disabled roster agent has its exact session;
- `unmanagedSessions`: named-socket sessions that are neither exact holder nor roster agent;
- `holder`: `owned`, `missing`, or `ownership-mismatch` after private identity and global environment checks.
Generated projection failures/staleness are surfaced by plan/apply preparation and bounded recovery fields rather than adopted as configuration. Heartbeat remains wider-fleet observational evidence, never desired state, but the current roster-v2 `status`, `doctor`, and `verify` commands do not read heartbeat files. A provable removed-agent projection may be treated as stale derived state during deletion, but general projection-orphan classification and installed source-versus-asset revision mismatch remain FCM-M4-002/M5-002 holds; current commands must not claim those future checks.
## Command behavior
`status` and `doctor` classify rather than adopt, destroy, or repair. `verify` is observational too, but exits non-zero if ownership cannot be proven, unmanaged sessions exist, or drift is present. Reconciliation fails closed under those conditions and never kills or adopts an unmanaged session.
Doctor/error output uses stable codes and bounded recovery context. Migration, quarantine, lifecycle, status, and troubleshooting output never prints a legacy sensitive value, credential, or privileged command text.
