How it fits

Section titled “How it fits”

This package keeps Neo4j driver, endpoint-scheme, and database-selection details out of Cephalon.Engine while still feeding the existing dependency-health contract. Hosts can opt into it when they need graph-database readiness to surface through /engine/dependencies, /health/live, /health/ready, and /engine/diagnostics without rewriting driver/session probes per host. When active, it also publishes its probe event ids through the shared runtime diagnostics catalog.
