# FCM-M5-001 Fleet Documentation IA Closure Evidence

**Issue:** #758 · **Task:** FCM-M5-001

## Artifact map

- Fleet entry point and desired/observed decision tree: `docs/fleet/README.md`.
- Concepts: `docs/fleet/concepts/` covers authority/projections, identity separation, role authority/leases, and the generated launch chain.
- Operator workflows: `docs/fleet/how-to/` covers CRUD, lifecycle, interaction and validator instances, and role overrides.
- Operations: `docs/fleet/operations/` covers reconciliation/recovery, quarantine, systemd/tmux troubleshooting, backup/restore boundaries, and upgrade-asset holds.
- References: executable schema, complete field/default/constraint reference, CLI/JSON/exit behavior, lifecycle/status/drift, role authority, and generated environment boundary under `docs/fleet/reference/`.
- Migration: preview field map, lifecycle preservation, backup/recovery prerequisites, aliases, and executable artifact dispositions under `docs/fleet/migration/`.
- Navigation: `docs/SITEMAP.md` and the fleet entry point.

| Sensitive/example safety                         | Validator scans every fenced fleet-book example plus the canonical roster for sensitive-looking keys, common credential formats, privileged commands, arbitrary command override, and hardcoded Tess/Ultron identities; docs consistently state value-free diagnostics. |

## Documentation completion checklist

- [x] Root PRD exists and remains the #758 requirements authority.
- [ ] The accepted project-specific fleet book is indexed, but it is not complete against `FCM-REQ-03`: the required explicit programmatic `mosaic fleet validate` operation is not implemented. The CLI reference and deferral report record this gap without inventing behavior.
- [x] Sitemap links the fleet entry point and operator-critical pages.
- [x] No HTTP/API/auth contract changed; OpenAPI/endpoint rows are not applicable.
- [x] Working evidence remains under `docs/scratchpads/`; closure and deferral evidence remains under `docs/reports/`.
- [x] Canonical source remains in-repository; no external publishing action is in scope.
- [ ] Independent exact-head documentation review, PR CI, and FCM-M5-002 release certificate remain post-PR gates and are not claimed here.

## Live-action boundary

No migration, canary, rollback, deployment, systemd/tmux/session operation, generated projection, or product mutation was performed. `roster.yaml` remains the sole writable desired-state authority. `mos-comms` remains temporary. Parent issue #758 remains open.

Validation command results and exact commit/tree evidence are recorded in the task scratchpad and PR body after execution.
