jakman85andClaude Opus 4.8 5c64e06354 fix(longhorn): cap concurrent-replica-rebuild-per-node-limit=1 (HDD etcd protection)
The k3s VM disks are HDD-backed, so a full Longhorn replica rebuild's
sequential I/O can saturate the spindle and starve etcd's WAL fsync,
crash-looping etcd and flapping the kube-vip VIP (observed during a
rolling node resize). Cap rebuilds to one replica per node at a time so a
node bounce or replica replenishment can never storm the disks.

Set via HelmRelease defaultSettings.concurrentReplicaRebuildPerNodeLimit
(GitOps-managed, permanent). replica-replenishment-wait-interval stays at
the Longhorn default of 600s. Reference values.yaml kept in sync.

jakman85andClaude Opus 4.8 cc89b4b830 Autonomous session: Phase-2 platform authoring + Flux bootstrap progress
Author-only Phase-2 components (platform suspended; cluster untouched):
- platform/longhorn: 3-replica SC + bulk external-mount indirection (R-STATE)
- platform/monitoring: kube-prometheus-stack + Loki + Alloy (dev-trimmed) + 8 alert rules (R-OBS)
- platform/cilium: parity fix (k8sServiceHost=10.73.0.11 + masquerade) safe to adopt Phase 2
- conformance: partial L2 tests (worker hit session limit; incomplete — see DECISIONS-LOG K2)
- bootstrap/gitea: fix rootless-podman perms (host bind-mount -> named volume)

Flux installed on the cluster; host Gitea up + repo pushed; GitRepository BLOCKED by
host firewalld (VM->10.73.0.1:3000) — needs one operator sudo command (DECISIONS-LOG).
Known issue K1: cluster-vars substitution-var case mismatch (fix before un-suspend).
