+## 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
+driven: the default report is `ready: false` until the caller supplies observed
+gate output such as `project_release_gate=ok` or explicit gate results.
+
+This helper does not execute shell commands and does not inspect or implement
+CNC behavior. It only packages project-level release evidence and blocked
+runtime policy that are already documented in `docs/project-release-handoff.md`
+and `../PROJECT_COMPLETION_TRACKER.md`.
