Production checklist

Before go-live

• Every node starts with its configuration and data directory, and GET /auth/issuers lists the password and api_key issuers.
• Users and roles exist for every person and service; each service signs in with its own API key.
• Federation sources report ready in system.sources.

At launch

• Transformations report healthy revisions in system.transformation_revisions.
• Streams deliver: system.psi_streams shows each subscription's lag.

Steady state

• Watch write pressure and WAL growth in system.storage.
• Read system.telemetry_metrics and system.health_signals; see Metrics and events.
