How it fits

Section titled “How it fits”

This package keeps Postgres-specific connection handling out of Cephalon.Engine while still feeding the existing dependency-health contract. Hosts can opt into it when they need managed database readiness to surface through /engine/dependencies, /health/live, /health/ready, and /engine/diagnostics without re-implementing connection-string parsing, SSL-mode handling, or health-query loops per host. When active, it also publishes its probe event ids through the shared runtime diagnostics catalog.
