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.
