Auth requiredAn authentication challenge is availability, not an outage — the endpoint is reachable and answering. Passive observation records the challenge and any OAuth discovery metadata without ever authenticating. OAuth-authenticated contract monitoring is planned.

Inventory locked behind authentication
This server challenges unauthenticated clients before listing tools, so passive observation cannot record a capability inventory. The challenge itself — and any OAuth discovery metadata — is recorded on this page. OAuth-authenticated contract monitoring is planned.
No contract recorded yet
The first successful discovery becomes rev 1 — a normalized inventory hashed centrally (normalizer v1). Every later observation is compared against the latest revision; when the canonical hash changes, a new snapshot is stored and the change is classified as a diff. Until a baseline exists there is nothing to drift from.
