+
+- Reserved bookings now have an audited checkout inspection. A safe inspection atomically
+  activates the booking and marks the vehicle rented; odometer regression, dirt, damage
+  or a technical warning blocks the booking and routes the vehicle to cleaning or
+  maintenance without an unsafe activation.
+- Operations Managers can register persisted maintenance evidence, advance service and
+  odometer values, explicitly release a vehicle only when no active rental or open
+  high-severity vehicle issue remains, and create/activate/deactivate operational users.
+  Self-deactivation and self-demotion are prevented. Rental employees receive 403 for
+  manager actions.
+- Added localized web workflows for checkout, maintenance/release and user access
+  administration. All actions use persisted API state and expose actionable errors.
+- Evidence: frontend lint and production build passed; ruff, mypy and diff check passed;
+  focused Unraid contracts **19 passed** and the full suite **208 passed, 1 warning**.
+- Exact next action: harden MCP per-client authorization and evidence completeness, then
+  replace inferred n8n status with explicit heartbeat/execution telemetry.
