# rail-knative Derived Railiance execution rail for Knative Serving workloads. This rail inherits the versioned `rail-kubernetes` common workload contract and owns only Knative-specific activation, scale-to-zero, revision, traffic, cold-start, and rollback semantics. The [declaration](declarations/rail.yaml) records `verified` readiness, backed by the [2026-07-26 lifecycle evidence](../reef-railiance/evidence/verification/rail-knative-v1.22.0-2026-07-26.json) on reef-railiance. This is not production approval. The [substrate runbook](docs/substrate-runbook.md) describes the declared CPU requests consumed by the railiance-cluster installer.
