The kyverno chart's cleanup jobs (policyReportsCleanup, webhooksCleanup) default to
bitnami/kubectl:1.30.2, which Bitnami removed from Docker Hub (2024 catalog purge) ->
ImagePullBackOff. policyReportsCleanup is a Helm post-upgrade HOOK, so its failure
stalls every helm upgrade (5m timeout -> HelmRelease not-Ready -> platform Kustomization
blocked -> platform-config/apps cascade). Override both to Bitnami's relocated
bitnamilegacy/kubectl (identical image: /bin/bash + awk/wc/xargs + kubectl). Verified
via helm template that no bitnami/kubectl reference remains.

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.

The wildcard cert stalled: challenge Presented=true (Cloudflare TXT created OK —
token works) but propagation self-check looped 'DNS record not yet propagated'.
Verified the record IS publicly resolvable (1.1.1.1/8.8.8.8); the NAT'd k3s-dev
cluster's own DNS just can't see it. Set dns01RecursiveNameservers=1.1.1.1:53,
8.8.8.8:53 + dns01RecursiveNameserversOnly=true so the self-check bypasses cluster
DNS. Realises the pre-existing TODO in this file.

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.

The un-suspend reconcile stalled: platform Kustomization Ready=False with
'StorageClass/longhorn ... .parameters.numberOfReplicas: expected string, got 3'.
StorageClass.parameters is map[string]string, but kustomize strips the quotes
around the bare "${LONGHORN_DEFAULT_REPLICA_COUNT}" placeholder, so Flux postBuild
substitution produced an unquoted numeric that server-side apply rejects as int.
Hardcode the quoted numeric literal "3" (kustomize preserves those, as "30" shows);
topology is locked at 3 nodes. The replica knob still drives the global default via
defaultSettings.defaultReplicaCount in the helmrelease (a Helm int value, unaffected).

- Rename the committed encrypted secrets to canonical cloudflare-api-token.sops.yaml
(cert-manager + external-dns namespaces) and uncomment the resource lines in both
kustomizations, so cert-manager DNS-01 + ExternalDNS get the token at reconcile.
- Exempt **/*.sops.yaml from ci/yamllint.yaml: SOPS re-emits encrypted files with its
own indentation + long ENC[...] lines (never hand-edited), which was failing the lint
gate on main after the secrets were committed. Same treatment as **/vault.yml.
Both Secrets confirmed present + encrypted in the platform 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.

Adopt the spec's Phase-0 clarifications (spec now at pin a7fc19f) into the impl:
- schema v1.1: enforce exposure:public => auth.mode!=none (positive+negative tested).
- Kyverno: add longhorn=>size and longhorn=>NOT-reacquirable invariants (R-STATE-02/03).
- Ratify the homelab.keithjackson.dev/* label-key convention (now in spec docs/03).
- R-TEST-06 spec-immutability gate: ci/SPEC_PIN + ci/spec-immutability.sh + gate.sh
stage + Makefile target + a Gitea job (checks spec repo clean & at pin).
- touched-requirements.sh: conformance tags are the authoritative source.
Reconcile 3 CI seams the CI worker flagged (gate was RED, now GREEN):
- create schemas/validate.sh (SCHEMA_VALIDATE_CMD entrypoint) — L0 schema gate runs.
- fix l1.sh/conformance.sh to run.sh's real interface (fixed _artifacts/ paths; no
--junit/--coverage) and collect artifacts.
- exec bits on new scripts.
make -C ci gate => PASS (l0 skips locally w/o kyverno binary; green in CI).

The prior integration commit enabled kyverno in the platform render, but (a) the
admission bundle used ../policies refs that fail default kustomize load
restrictions, and (b) admission enforcement is Phase 2 (T-2.7), not Phase 0.
Fix: platform/kyverno/kustomization.yaml now lists resources with downward paths
(builds standalone); platform/kustomization.yaml re-defers kyverno with a Phase-2
note. All Phase-0 gates green: kustomize (platform, platform/kyverno, dev),
schema validation, conformance scaffold.

Add platform/kyverno/kustomization.yaml (renders the admission enforcing bundle)
and enable the kyverno component in platform/kustomization.yaml (first, so
admission policies precede other components). kustomize build verified.
