How it fits
Section titled “How it fits”This package keeps Cassandra-native contact-point, keyspace, and query handling out of Cephalon.Engine while still feeding the existing dependency-health contract. Hosts can opt into it when they need Cassandra readiness to surface through /engine/dependencies, /health/live, /health/ready, and /engine/diagnostics without rewriting cluster-session probes per host. When active, it also publishes its probe event ids through the shared runtime diagnostics catalog.
