Text-only cleanup after the upgrade campaign. Updates stale version strings, prose, and comments to the verified current facts; no Kubernetes behavior or version pins changed except the kubectl toolchain bump (below). Verified facts applied: k3s v1.36.4+k3s1, Debian 13 trixie, Cilium 1.20.1 / Gateway API v1.6.1, Longhorn 1.12.1, node RAM 24 GiB, dedicated virtio2 SSD etcd disk per node, Velero chart 12.x / v1.18, Grafana 13.2.0. - Version strings across infra/ and platform/ READMEs + comments - kubectl toolchain 1.31.4 -> 1.36.4 (devcontainer/ci/conformance versions.env; 1.31 vs a 1.36 cluster exceeded the +-1 skew) - Retired-single-apps-Kustomization refs -> apps-wave-0/1/2 + apps-vms with per-wave SOPS decryption (flux/clusters docs + bootstrap.sh) - COMPLETED/historical banners on the three executed plan docs - Resolved TODO(WS-SEC) markers -> Renovate-maintained ranges - Appended dated DECISIONS-LOG entry (2026-08-30) superseding the 2026-08-26 LIVE STATE line Left as revalidation items (not blind-edited): external-snapshotter v8.2.0 vs 1.36, Cilium ext_authz/forward-auth relevance under 1.20.1, conformance ImageVolume feature-gate assertions under 1.36.

platform/cnpg
CloudNativePG — the PostgreSQL operator that runs Keycloak's DR-critical database.
- Governing ADR: ADR-0014 — IdP: Keycloak
- Serves: R-IDP-05 (DR-critical datastore), supports R-IDP-01
- Owner: WS-SEC
Why CNPG (not the Bitnami-bundled Postgres)
The original Keycloak stub used the Bitnami Keycloak chart with a bundled Bitnami PostgreSQL. Bitnami's free Docker Hub images were purged/relocated (DECISIONS-LOG F-KY1) — a deploy on stock Bitnami tags ImagePullBackOffs. CloudNativePG:
- ships from ghcr.io/cloudnative-pg (unaffected by the Bitnami purge),
- runs Postgres as a replicated
Clusteron Longhorn (3 instances → survives node loss), - gives declarative backup/restore (
ScheduledBackup+ Barman object store) — the clean DR hook for R-IDP-05 (off-cluster backup) once the backup target lands (OQ-BKP, Phase 4).
Controllers/configs split (F-MON1)
This directory installs only the operator + CRDs (controllers). The keycloak database Cluster
CR lives in ../../platform-config
(dependsOn: platform, wait) so the postgresql.cnpg.io CRDs exist before the CR applies.
