+The fixed Git/ArgoCD transport adapter and persistent health observer are now
+implemented and tested with disposable real Git repositories and simulated
+Kubernetes responses. Real Git rollback, lost-response recovery, concurrent-writer
+refusal and wrong-cluster refusal pass. Health attestation requires a full 24 hours
+of actual samples, no more than 90 seconds apart; gaps and clock regressions reset
+or invalidate the interval. It cannot infer that history from the rollout timestamp.
+Production credential admission, real invariant probes/signing issuers, Temporal
+registration and authenticated Kubernetes failure tests remain open. See the
+[broker implementation](../../activity-core/docs/release-broker.md) for that boundary.
