Retirement
The owner confirmed removal from the fleet on September 20, 2026. Active inventory, operational checks, dashboard catalog, query registration and managed alerts were removed. Deployment no longer contacts this server. No server data, credentials or historical incident records were deleted. Raspberry monitoring retains its own metrics.
Reintroduction requires an explicit inventory and deployment change; do not run the archived enrollment scripts.
Restore membership verification
The Observe drill checks exact active system identities against the archived inventory and operational configuration, rather than a historical fixed fleet size. Missing systems, same-count substitutions, duplicates, empty inventories and retired identities fail verification. Operational history and owner dashboard checks remain required. The old 29-system assertion failed after retirement; no passing restore credit is accepted until the corrected full drill succeeds.
