- tag: Server
  spec_file: nats-server-api-openapi.yml
  capability_id: BC-4220.20
  capability_id_l1: BC-4220
  capability_name: Observability Management
  confidence: 0.75
  evidence: GET /varz  getVarz  General server information; GET /ipqueuesz  getIpqueuesz  IP queue sizes
    — "real-time server statistics ... for observability and operations"
  reason: Core monitoring endpoints returning general server variables and internal queue sizes; clearly
    production observability metrics for the running service.
- tag: Connections
  spec_file: nats-connections-api-openapi.yml
  capability_id: BC-4220.20
  capability_id_l1: BC-4220
  capability_name: Observability Management
  confidence: 0.7
  evidence: GET /connz  getConnz  Connection information — "real-time server statistics including connection
    info ... for observability and operations"
  reason: Read-only runtime metrics about broker connections exposed for monitoring; this is observability
    instrumentation of a running service.
- tag: Gateways
  spec_file: nats-gateways-api-openapi.yml
  capability_id: BC-4220.20
  capability_id_l1: BC-4220
  capability_name: Observability Management
  confidence: 0.7
  evidence: GET /gatewayz  getGatewayz  Gateway information — "monitoring HTTP endpoint ... for observability
    and operations"
  reason: Exposes gateway (cluster interconnect) runtime statistics for monitoring purposes; observability
    of the running messaging service, not API gateway product management.
- tag: JetStream
  spec_file: nats-jetstream-api-openapi.yml
  capability_id: BC-4220.20
  capability_id_l1: BC-4220
  capability_name: Observability Management
  confidence: 0.7
  evidence: GET /jsz  getJsz  JetStream information — "JetStream metrics, and health checks for observability
    and operations"
  reason: Returns runtime metrics for the JetStream persistence subsystem via the monitoring endpoint;
    observability telemetry of the running service.
- tag: Leaf Nodes
  spec_file: nats-leaf-nodes-api-openapi.yml
  capability_id: BC-4220.20
  capability_id_l1: BC-4220
  capability_name: Observability Management
  confidence: 0.7
  evidence: GET /leafz  getLeafz  Leaf node information — "monitoring HTTP endpoint that provides real-time
    server statistics"
  reason: Read-only leaf-node connection statistics served by the monitoring endpoint; observability of
    production infrastructure.
- tag: Routes
  spec_file: nats-routes-api-openapi.yml
  capability_id: BC-4220.20
  capability_id_l1: BC-4220
  capability_name: Observability Management
  confidence: 0.7
  evidence: GET /routez  getRoutez  Route information — "route details ... for observability and operations";
    schema Routez
  reason: Cluster route statistics exposed for monitoring, not network routing configuration or logistics
    routing; maps to observability.
- tag: Subscriptions
  spec_file: nats-subscriptions-api-openapi.yml
  capability_id: BC-4220.20
  capability_id_l1: BC-4220
  capability_name: Observability Management
  confidence: 0.7
  evidence: GET /subsz  getSubsz  Subscription information — "subscription data ... for observability
    and operations"; schema Subsz
  reason: 'Homograph: these are pub/sub message subscriptions reported as monitoring statistics, not commercial
    SaaS subscriptions. Maps to Observability Management, not subscription lifecycle.'
