 - Namespace `coulomb` was kept. Besides the defaults, it may still hold the probe's manually created env credential object, which agents may not inspect. The founder checks what is left and deletes the namespace if only that probe object remains.
 - DNS for probe.coulomb.social still needs review.

+Read-only check from the workstation kube context `default` (user `ops-mason-builder`):
+
+- `kubectl get ns` has no namespace named `coulomb`. The conditional namespace delete from the 2026-10-21 uninstall is done.
+- `probe.coulomb.social` A is NXDOMAIN (SOA `ns1045.ui-dns.org`).
+- No deployable reference in `rapp-core-hub` or `railiance-apps`. Remaining mentions are historical inventories (`railiance-platform` namespace-ownership and resource-control evidence), not a Helm release or ArgoCD Application in those charts.
+
+This session could not list pods, Helm releases, or ArgoCD Applications in `coulomb` (forbidden for `ops-mason-builder`, and the namespace is already absent). The uninstall receipt above remains the write evidence.

 ## Applied — 2026-10-22 (CORE-WP-0012-T01)
 
 Applied under the founder's wave-2 authorization (the-custodian docs/decisions/2026-10-21-cust-wp-0071-delivery-interview.md), after a full-render diff against live that showed resources only. rapp-core-hub `make deploy`, Helm revision 34; all three Deployments are Ready. Evidence: the-custodian docs/evidence/2026-10-22-wave2-apply.md.
