 Apply order is documented in `docs/operator-runbook.md`. Do not apply the
 Deployment until:
 
-1. The image digest is pinned (currently `sha256:ec15f63d…` from commit `bc3d80f`).
+1. The image digest is pinned (currently `sha256:b479801b…` built from source commit `5227fb14e47f26a01930be4611360fd90f740662`).
 2. Secrets `audit-core-database`, `audit-core-database-migrate`, and
    `audit-core-senders` exist. ConfigMap `audit-core-senders-scope` is
    applied (`deploy/senders-scope.yaml`) before the Deployment mounts it.

+   deliberately selects component `receiver` only. Migration pods need their

+   kube-system and PostgreSQL TCP5432 to platform-pg pods in databases.
+   No API-server access or service account token is needed.

+The 2026-10-15 NK-WP-0035 migration retries exposed this missing dedicated
+egress exception: the first two attempts could not resolve/reach PostgreSQL.
+The bounded policy is retained as source so future releases do not depend on
+an undocumented repair. Both receiver and migration Job pin immutable image
