# Credential delivery for audit-core (AUDIT-WP-0005-T02).
#
# Two sources, because they are two kinds of secret:
#   - database leases: VaultDynamicSecret -> ExternalSecret (this file)
#   - sender registry: ClusterSecretStore openbao-audit-core -> ExternalSecret
#
# audit-core never holds a credential in its own configuration; it reads
# whatever is currently mounted. Apply order: namespace, ESO token,
# ClusterSecretStore, VaultDynamicSecret, this, migrate Job, Deployment.
