RBAC: the built-in view ClusterRole (which never includes Secrets, so Vault-managed material stays structurally invisible) plus a read-only extra for nodes, namespaces, PVs, storage classes, CRDs, Flux resources and metrics, bound to the chat service account. Tooling: a cluster-read plugin registers a GET-only cluster_read tool against the in-cluster API using the pod's projected token - secrets paths refused in the handler as well, malformed segments rejected, responses bounded and stripped of managedFields noise. Classified read_files/low in the HUX capability map. RBAC applies on push; the tool activates when the pods next roll (bundled with the round-3 voice build).

# Chat's read-only window onto the cluster. The built-in `view` ClusterRole

# structurally excludes Secrets everywhere, so Vault-managed material and
|

# other credential Secrets stay invisible; the extra role adds the read-only

|
# cluster-scoped objects `view` does not cover. No write verbs anywhere.
