The on-cluster cluster-vars ConfigMap wasn't reconciled by Flux — this bootstrap
model had no Kustomization watching clusters/dev, so cluster-vars/overlay changes
needed a manual 'kubectl apply -k clusters/dev' (e.g. DNS_ZONE substituted empty
until re-applied). Add clusters/dev/sync.yaml: a self-managing root Kustomization
(flux2 gotk-sync pattern, name flux-system) that reconciles ./clusters/dev from git
— cluster-vars, the GitRepository, platform/platform-config/apps, and itself. A git
push now suffices. Bootstrap unchanged ('kubectl apply -k clusters/dev' creates it
once). Verified: dev build contains all 6 objects (root + existing), prod unaffected.

Phase-2 exit tests (were Phase-0 scaffolds), authored against the live platform:
- trusted-tls (R-TLS-01/03): in-cluster probe dials the gateway Service (env-agnostic
via --connect-to) with wildcard SNI and verifies the served cert CHAINS TO THE LE
STAGING ROOT (operator decision A; dev uses LE-staging per ADR-0006). Fixture embeds
the '(STAGING) Pretend Pear X1' root. Probes public + internal-only hostnames (R-TLS-03).
PASSES.
- dns-exposure (R-DNS-02): a LoadBalancer Service with an external-dns hostname; polls
public DNS until ExternalDNS auto-publishes the record; teardown + policy=sync removes it.
ExternalDNS fix (root cause of the DNS test): domain-filter was the platform SUBDOMAIN
home.keithjackson.dev, which filters OUT the actual Cloudflare zone keithjackson.dev
('no hosted zone matching record DNS Name' — record generated but skipped). Add a
DNS_ZONE cluster-var (keithjackson.dev) and set domainFilters to it. policy=sync +
txt-registry still only manage ExternalDNS-owned records (the pre-existing wildcard is
untouched). Resolves the file's WS-NET R-DNS-02 TODO.

Kyverno HelmRelease install failed at Helm templating: config.webhooks was a
LIST [{failurePolicy, namespaceSelector}], but the kyverno 3.3.9 chart expects
config.webhooks to be a MAP (webhooks.namespaceSelector) — the chart helper reads
.namespaceSelector off the value directly ('can't evaluate field namespaceSelector
in type []interface {}'). Also, failurePolicy is not a per-webhook field here; the
chart's global switch is config.forceFailurePolicyIgnore.enabled (bool).
Fix: config.webhooks -> map with namespaceSelector (system+platform excludes);
add config.forceFailurePolicyIgnore.enabled = ${KYVERNO_FORCE_FAILURE_POLICY_IGNORE}.
Renamed the cluster-var KYVERNO_WEBHOOK_FAILURE_POLICY (Fail/Ignore) ->
KYVERNO_FORCE_FAILURE_POLICY_IGNORE (false base / true dev). Verified with
helm template (renders 73 objects, no error); gate PASS.

Un-suspend deadlocked: the single platform Kustomization applies HelmReleases
(which register CRDs) AND custom resources of those CRDs (ClusterIssuer,
Certificate, Kyverno ClusterPolicies) in ONE pass. Flux's server-side apply
fails atomically ('no matches for kind ClusterIssuer') → nothing installs, so
the CRD-registering HelmReleases never run either. Classic ordering deadlock.
Fix (flux2 controllers/configs pattern, applies to dev+prod equally — no
R-ENV-02 divergence): add a platform-config Flux Kustomization (dependsOn
platform, wait) carrying the CRs; platform keeps only the controllers.
- New clusters/base/platform-config.yaml (path ./platform-config, substituteFrom
cluster-vars, no decryption — no SOPS content); wired into base + apps now
dependsOn platform-config (transitively waits for platform).
- platform-config/ references the CR files IN PLACE via ../platform/... (Flux
builds LoadRestrictionsNone; Kyverno policies must stay under platform/kyverno/
for the CI L0 gate). CR resources dropped from the platform
component kustomizations (cert-manager, gateway, kyverno).
- Authored the missing Cilium L2 resources (were only a TODO): CiliumLoadBalancerIPPool
(dev NAT 10.73.0.240-.250) + CiliumL2AnnouncementPolicy (ens*), so Gateway
LoadBalancer listeners get a VIP. Prod range must be parameterized later.
Verified: platform build has zero CRs; platform-config build has 2 ClusterIssuers,
6 ClusterPolicies, Certificate, Gateway, both Cilium L2 CRs; dev/prod build; gate PASS.

Prep only — nothing deployed; running cluster untouched.
Reconciliation graph (operator-approved Option A): author clusters/dev/rollout/
= 4 per-component Flux Kustomizations (kyverno->cilium->longhorn->monitoring,
monitoring dependsOn longhorn). Dev overlay $patch:delete's the monolithic base
platform/apps and adds ./rollout, so only the no-secret tier reconciles; the
secret-blocked components are simply not created until hand-offs arrive. The
no-secret tier carries no SOPS content, so it needs no sops-age key. prod is
untouched (still builds the monolith). Convergence path coded in (delete rollout/
+ the two deletes) — R-ENV-02 divergence flagged for architect review.
Component hardening via cluster-vars (prod keeps strict posture):
- KYVERNO_VALIDATION_ACTION Enforce->Audit(dev), _WEBHOOK_FAILURE_POLICY
Fail->Ignore(dev), _ADMISSION_REPLICAS 3->1(dev); webhook namespaceSelector
excludes system+platform namespaces.
- MONITORING_STORAGE_CLASS var; GRAFANA_ADMIN_SECRET var (dev ''=chart default);
Alertmanager SMTP/secret deferred to Phase-4 with verbatim re-enable markers.
Cilium parity verified against the live CNI (no-op adopt). Validated:
kubectl kustomize dev/prod/all-components, envsubst->YAML parse, make -C ci gate PASS.

Flux postBuild.substituteFrom is case-sensitive; platform/ components reference
${UPPERCASE} tokens but cluster-vars keys were lowercase -> none would resolve
(literal ${...} would reach the HelmReleases). Uppercased the ConfigMap data
keys + the dev/prod overlay patch paths. Every component ref now resolves;
clusters/dev & clusters/prod build; gate green. Clears the K1 landmine before
any platform un-suspend.

Run a single Gitea container on the host (bootstrap/gitea/), outside the cluster,
while the cluster is built; Flux pulls this repo from it over the k3s-dev NAT
gateway (http://10.73.0.1:3000/Home-Network/home-network-k3s-impl.git, public repo
=> no creds, NAT-only). Wired the flux-system GitRepository url in clusters/dev.
Migrates to in-cluster Gitea in Phase 6. Pins confirmed. Author-only; gate PASS.

Phase 0 foundation shell (read-only spec at ../home-network-k3s). Top-level
