# NK-WP-0058-T05: read-only status for the agent identity (proposal, 2026-11-06)
**Status: proposed, for founder decision.** Nothing is applied.
**Status: decided 2026-11-06, option A with 1 h tokens** (State Hub `4af1ec01`). Not yet applied: it waits for the
owner's review.
## Why
@ -53,17 +54,36 @@ literal secret values (only file paths, references and URLs). `tools/contract-te
keeps it that way and keeps the grant read-only and narrow.
**Tokens:** at most 1 hour (SI-14), minted by the founder once per working session. This is read-only, so it isn't a
warden lane:
```bash
kubectl --kubeconfig ~/.kube/config-railiance01 -n sso create token nk-agent-status --duration=1h \
> ~/.kube/nk-agent-status.token && chmod 600 ~/.kube/nk-agent-status.token
```
warden lane: `make agent-status-token` (founder steps below).
The agent's kubeconfig `~/.kube/config-agent-status` names the cluster and `tokenFile: ~/.kube/nk-agent-status.token`.
It holds no token itself. A longer token is a deviation from SI-14 and would need its own decision.
**Who applies it:** railiance-cluster owns cluster RBAC, so after the decision the change goes there as a reviewed
change. The founder applies it, server-side. Verification:
- `kubectl auth can-i --list` as `nk-agent-status` shows only these rules;
- `can-i get secrets -n sso` and `can-i get pods --subresource=log -n sso` both answer `no`.
**Owner:** railiance-platform. Agent-facing cluster grants live there as platform add-ons, the precedent being
`argocd/platform-addons/ops-mason-builder/`, applied by a manually synced, pinned Argo Application. The proposal first
named railiance-cluster, which has no RBAC manifests. railiance-platform is asked to adopt `rbac.yaml` the same way,
as `argocd/platform-addons/nk-agent-status/`. Unlike ops-mason-builder's certificate User, this identity is a
ServiceAccount with 1 h tokens (SI-14).
## Founder steps after the owner's commit
1. **Once:** sync the reviewed Application in Argo CD, as for ops-mason-builder.
2. **Once:** build the agent's kubeconfig. It holds the cluster's CA and a pointer to the token file, never a token.
No command prints a credential:
```bash
A=~/.kube/config-agent-status
kubectl --kubeconfig ~/.kube/config-railiance01 config view --raw --minify \
-o jsonpath='{.clusters[0].cluster.certificate-authority-data}' | base64 -d > ~/.kube/railiance01-ca.crt
kubectl --kubeconfig $A config set-cluster railiance01 --server https://127.0.0.1:16444 \
--certificate-authority ~/.kube/railiance01-ca.crt --embed-certs >/dev/null
kubectl --kubeconfig $A config set users.nk-agent-status.tokenFile "$HOME/.kube/nk-agent-status.token" >/dev/null
kubectl --kubeconfig $A config set-context nk-agent-status --cluster railiance01 --user nk-agent-status >/dev/null
kubectl --kubeconfig $A config use-context nk-agent-status >/dev/null && chmod 600 $A && echo agent-kubeconfig-ok
```
3. **Each working session:** `make agent-status-token` mints a 1 h token into `~/.kube/nk-agent-status.token`
(mode 600) and prints one line.
The agent then verifies with `kubectl --kubeconfig ~/.kube/config-agent-status auth can-i --list` and the two
negative checks: Secrets and pod logs in `sso` answer `no`.
