What this claim says

label: Stream age / TX-per-minute indicator reflects actual xrpl_stream activity
page: /health
claim id (yaml): health_stream_freshness
behavior: CONTINUOUS_WIGGLE
Layer 3 source: self-attested-only

Risk note

/health is the primary human-readable alarm surface. If /health itself is wrong (shows OK while stream is stale), it defeats the monitoring layer. The four-layer audit treats /health indicators as the highest-trust assertions — if L2/L3 alarms exist but /health shows OK, alarm propagation is broken.
