Read node status first, then build identity, delegation, and event responsibility chains

/healthz returns node status, origin_fingerprint, and the Prime RootTHK sync summary. Clicking “Check Connectivity” above automatically fills the origin fingerprint used by this page. The default ClaimAnchor and GrantAnchor samples also auto-fill test keys, subject fingerprints, and predecessor anchors so you can run the full responsibility chain end to end.

ClaimAnchor Lock down who is acting. A ClaimAnchor records the subject fingerprint, attribute type, attribute digest, and both subject and issuer signatures.
GrantAnchor Lock down who delegates to whom and under what scope. The default sample auto-creates a temporary ClaimAnchor pair and builds the delegation edge on top.
EventAnchor Finally, write the operational event anchor and reference the most recent ClaimAnchor and GrantAnchor in semantic_anchor to complete the responsibility chain.
Python 
health = await client.healthz()
print(health.status)
print(health.origin_fingerprint)
print(health.prime_root_thk_sync.status)
TypeScript 
const health = await client.healthz();
console.log(health.status);
console.log(health.originFingerprint);
console.log(health.primeRootThkSync?.status);
Rust 
let health = client.healthz().await?;
println!("{}", health.status);
println!("{:?}", health.origin_fingerprint);
println!("{:?}", health.prime_root_thk_sync);
Current VPS monitoring surface
Public health, private metrics

The current production VPS already runs Prometheus and Alertmanager. Public clients use /healthz and business APIs; /metrics stays on host-only or private-network scrape paths.

Public GET /healthz and GET /readyz for integration checks and liveness.
Private scrape 127.0.0.1:15051/metrics
127.0.0.1:18110/metrics
127.0.0.1:18090/metrics
