+## Project release readiness export
+
+`createProjectReleaseReadinessReport()` returns a machine-readable release
+readiness report for CI dashboards and external SDK callers. The report lists
+the required project release gate command, expected smoke outputs, the current
+sim-config inventory baseline, and blocked runtime families. It is evidence
