+Operator said "go" for the un-suspend, then went AFK: "continue to work without me. Any major decision
+that requires a system architecture change VIA SPEC CHANGE will need to be escalated. Anything else is
+allowed. Keep track of assumptions and report on return." None of the below is a spec change (the spec
+is silent on Flux Kustomization granularity / L2 wiring), so all within PM remit. **Nothing touched the
+read-only spec repo.**
+
+- **Un-suspended** via the sanctioned `kubectl apply -k clusters/dev` (bootstrap.sh step 3): controllers
+  already installed, `sops-age` present. Pre-deploy checks all green first — Cilium adoption safe (an
+  existing `helm` release `cilium` v3 exists → Flux adopts by name, no-op upgrade), Longhorn node prereqs
+  green on all 3 nodes (`iscsid` active, `/var/lib/longhorn`→`/dev/vdb`), host Gitea pushed + Flux source Ready.
+
+### Fix 1 — Longhorn StorageClass numeric coercion (commit ~c04aea8)
+Reconcile stalled: `.parameters.numberOfReplicas: expected string, got 3`. kustomize strips the quotes
+around a bare `"${VAR}"` placeholder, so Flux substitution yielded an unquoted numeric that SSA rejects
+(StorageClass.parameters is map[string]string). **Hardcoded `numberOfReplicas: "3"`** (quoted numeric
+literals ARE preserved by kustomize; topology LOCKED at 3). The replica knob still drives the global
+default via `defaultSettings.defaultReplicaCount` in the helmrelease (a Helm int value, unaffected).
+
+### Fix 2 — DECISION: controllers/configs split (commit ~458a867) — NOTABLE, please review
+Reconcile then failed atomically: `no matches for kind "ClusterIssuer"`. The single `platform`
+Kustomization applied HelmReleases (which register CRDs) AND CRs of those CRDs (ClusterIssuer,
+Certificate, Kyverno ClusterPolicies) in one pass → Flux SSA fails the WHOLE apply → the CRD-registering
+HelmReleases never run. Deadlock. **Adopted the flux2 controllers/configs pattern:** new
+`platform-config` Flux Kustomization (`dependsOn: platform`, wait) carries the CRs; `platform` keeps only
+controllers; `apps` now `dependsOn platform-config`. Applies to dev AND prod (shared base) — no R-ENV-02
+divergence. `platform-config/` references the CR files IN PLACE via `../platform/...` (Flux builds with
+LoadRestrictionsNone; Kyverno policies must stay under `platform/kyverno/` for the CI L0 `kyverno test`
+gate) — **ASSUMPTION: Flux's default LoadRestrictionsNone permits the `../` refs** (builds verified
+locally with `--load-restrictor LoadRestrictionsNone`; confirming at reconcile).
+
+### Fix 3 — Authored the missing Cilium L2 resources (in Fix 2 commit)
+`l2announcements.enabled: true` was set but the IP pool + announcement policy were only a TODO, so a
+Gateway LoadBalancer would never get an IP. Authored `platform-config/cilium/`: **CiliumLoadBalancerIPPool**
+(dev NAT range **10.73.0.240-.250**, matching the tofu reservation) + **CiliumL2AnnouncementPolicy**
+(interface regex `^en`, node interface is `ens3`). **ASSUMPTIONS:** (a) VIP range hardcoded to the dev
+NAT range — a prod overlay must parameterize it (via cluster-vars) when prod is built; (b) `^en` matches
+the node LAN NIC (`ens3`); (c) CRD apiVersion `cilium.io/v2alpha1` (confirmed served on the cluster).
+
+### Result
+Un-suspend reconcile in progress at last checkpoint (controllers installing → platform-config → apps).
+Outcome + any further fixes appended when the reconcile settles.
