+# Grafana administrator custody
+
+This is the attended bootstrap lane for rapp-telemetry on railiance01, not a
+coding-agent credential vending interface or an accepted operator OIDC design.
+User authorized service activation on September 6, 2026.
+
+- KV: platform/workloads/telemetry/grafana-admin; ADMIN_USERNAME and ADMIN_PASSWORD.
+- ESO identity: telemetry/telemetry-grafana-eso, automount disabled.
+- Kubernetes auth role: telemetry-grafana-eso; policy telemetry-grafana-admin-eso.
+- Exact data-only read, self-lookup/revoke, audience openbao, 15-minute maximum;
+  no default policy, wildcard namespace, sibling grant or secret write.
+- ClusterSecretStore openbao-telemetry-grafana restricts consumers to telemetry;
+  ExternalSecret telemetry-grafana-admin refreshes every 5 minutes and retains
+  the delivered Secret. Grafana references admin-user and admin-password.
+- Coding-agent high-risk boundary denies both data and metadata, including when
+  combined with the ESO read policy. Cluster administration/ESO remain trusted.
+
+Source manifests belong to ../rapp-telemetry/manifests/. The platform writer
+scripts/telemetry_grafana_custody.py uses CAS zero, refuses existing role/policy
+or credential shape drift, preserves existing boundary policy text, and checks
+positive and negative login/access before verifying ESO delivery. Run only under
+scripts/openbao-attended-exec.py after warden route show
+openbao-platform-admin-login. A unique --receipt path is required; receipts contain
+metadata only. The bootstrap does not rotate existing credentials.
+
+scripts/telemetry_grafana_access.py checks anonymous and forged proxy-header
+denials, positive native-admin API access, datasource and dashboards inside the
+same attended envelope. It requires an operator-created localhost-only port
+forward on 13001 to the known Grafana service. Do not substitute an untrusted
+endpoint. It emits only a metadata receipt and never logs passwords or headers.
+
+Rotation must update the existing Grafana database administrator credential as
+well as OpenBao; changing ESO/environment alone does not reset an initialized
+Grafana admin password. Coordinate and test old-login rejection/new-login success
+before calling rotation complete. Disable the ESO role to revoke future delivery
+but remember the existing Kubernetes Secret and application password persist;
+revoke application access and remove the binding deliberately in a compromise.
+Do not delete retained recovery material as an implicit rollback.
+
+Accepted September 6 evidence: exact read and delivery match; wrong identity,
+namespace and audience denied; sibling/write denied; coding-agent deny wins;
+native login succeeds; anonymous/proxy-header requests denied. See
+../rapp-telemetry/evidence/live/2026-09-06-railiance01.json. Independent backup and
+isolated restore, operator OIDC and public production admission remain open.

+# Telemetry private activation — 2026-09-06
+
+User supplied telemetry.coulomb.social and authorized continuing on railiance01.
+The separately owned rapp-telemetry package is now installed privately (Helm
+revision 4, pinned kube-prometheus-stack 89.2.3). All five workloads are ready,
+12/12 configured targets are up, and three PVCs are bound. DNS resolves to the
+node and cert-manager issued the hostname certificate. Public ingress is staged,
+not applied; Master ADR-0006/0008 admission remains incomplete.
+
+Platform established platform/workloads/telemetry/grafana-admin with CAS-zero
+protected generation and dedicated ESO identity telemetry/telemetry-grafana-eso.
+The exact role/policy is telemetry-grafana-eso / telemetry-grafana-admin-eso;
+audience openbao, 15-minute maximum, no default policy. Native credential values
+were compared with ESO delivery only inside the attended envelope. The coding
+agent boundary denies both data and metadata, preserving existing live policy.
+Positive read, sibling/write denial, wrong SA/namespace/audience rejection and
+deny-over-read policy union checks passed. Attended sessions self-revoked.
+
+Grafana native admin authentication works; anonymous and forged proxy headers
+return 401. Grafana retained its PVC through an update and still has 20 provisioned
+dashboards plus its Prometheus datasource. Same-namespace service/pod access
+works; an unrelated namespace is rejected. A chart default route referenced an
+undefined Alertmanager receiver; explicit route replacement fixed it and a
+rendered-config check now guards against recurrence. Grafana uses Recreate
+updates to keep one SQLite writer.
+
+Custody details and lifecycle limitations: docs/credential-lane-designs/telemetry-grafana.md.
+Deployment evidence: ../rapp-telemetry/evidence/live/2026-09-06-railiance01.json.
+Detailed handoff: ../rapp-telemetry/docs/activation-2026-09-06.md.
+
+RAPP-TELEMETRY-WP-0001-T03 remains progress for isolated restore and independent
+custody. T04 still waits for operator OIDC, actual S3 signal delivery/receipt,
+an outside-node watchdog and public admission. RPF-WP-0036 is not closed by this
+installation. Primary backup remains Scaleway; do not fill the 10GB Nextcloud
+Backup account with telemetry time series. It is for the agreed essential set.
