 ## Runtime secrets
 
-Custody is the Kubernetes Secret `reuse-surface-env` in namespace `reuse` on
-Railiance01. This is **not** an OpenBao KV path today — see
-**RAILIANCE-WP-0011** for a planned OpenBao + External Secrets migration.
+Custody is OpenBao KV at
+`platform/workloads/reuse/reuse-surface/runtime-secrets` on coulombcore
+(`https://bao.coulomb.social`), delivered to the workload through External
+Secrets (`ExternalSecret reuse/reuse-surface-runtime` → Secret `reuse-surface-env`,
+`ClusterSecretStore openbao-reuse`). Lane: **CCR-2026-0005** /
+**RAILIANCE-WP-0011**.
