Operator decisions, 2026-09-01:
1. Prod uses the SAME SOPS age key as dev.
2. Prod tracks the SAME BRANCH as dev (`main`). Dev is a temporary instance and will be
decommissioned once prod is deemed stable.
SOPS: eight `decryption: {provider: sops, secretRef: sops-age}` patches mirroring dev
exactly — platform, apps-wave-0/1/2, oauth2-proxy, headlamp, crafty, velero. The sops-age
Secret is still created OUT OF BAND on prod (bootstrap/sops/install-age-key.sh); the
overlay references it by name only, never inlines key material.
RECORDED CONSEQUENCE of the shared branch: once prod is live, EVERY MERGE TO main
RECONCILES BOTH CLUSTERS. There is no promotion step and no soak window — dev and prod
move together. That is a deliberate consequence of dev being temporary, not an oversight,
but it removes the "prove it on dev first" safety net that the last few days have leaned
on heavily. Worth revisiting if dev outlives its expected life.
*** BOOTSTRAP BLOCKER recorded, NOT papered over *** — the source URL cannot work on a
cold prod cluster, for two independent reasons found while wiring this:
1. SELF-HOSTING CIRCULARITY. Gitea runs ON THE DEV CLUSTER — the one slated for
decommission. Prod syncing from it means prod's source of truth lives inside the
cluster being retired. Gitea must move to prod (or off-cluster) BEFORE dev is torn
down. This makes Gitea migration the FIRST task of the decommission plan, not the last.
2. SPLIT-HORIZON DNS SENDS IT TO THE WRONG PLACE. platform/coredns/coredns-custom.yaml
answers the ENTIRE home.keithjackson.dev zone with ${GATEWAY_VIP} via a template
plugin. On prod that is 192.168.2.20 — PROD's own gateway, where no Gitea listens. Prod
Flux would resolve gitea.home.keithjackson.dev to itself and never reach a repository.
This is the same split-horizon mechanism that makes dev work, inverted against us.
Bring-up therefore needs a TEMPORARY source (the bootstrap host-Gitea, or an off-cluster
mirror) with a cutover to the in-cluster URL once Gitea actually runs on prod — precisely
the sequence docs/05 describes for dev's own Phase-6 cutover. The branch is settled and
correct; only the host is blocked. Documented at the patch site and in
PROD-PROVISIONING.md §7.
Gate: MERGE GATE: PASS.
Serves: R-SEC-01, R-GITOPS-01, R-ENV-02, R-ENV-03. Task: T-7.1.

home-network-k3s-impl
Implementation of the home k3s + Longhorn platform. This repo holds the reconciled artifacts
(Flux config, Kustomize overlays, KubeVirt/Helm manifests, ServiceDefinitions, Kyverno policies,
Chainsaw conformance tests, CI). It is driven by — and subordinate to — the read-only
specification at ../home-network-k3s.
Rules (from the spec — non-negotiable)
- The spec is read-only. Never modify anything under
../home-network-k3s. Implement against it; escalate spec problems, don't edit them (specAGENTS.md§11, R-TEST-06). - Done = a green, reproducible, requirement-tagged conformance test — never "merged," never a
manual demo (spec
docs/14,agents/definition-of-done.md). - No work on
main. Every change is a feature branch merged intomain(specCONTRIBUTING.md). - No plaintext secrets — SOPS-encrypted only (spec
docs/07). - Phase discipline — only build what the active roadmap phase authorizes (spec
roadmap/phases.md).
Layout
infra/ node provisioning: OpenTofu (Proxmox VE) + cloud-init + Ansible, and the
pinned dev container that carries the whole toolchain
bootstrap/ one-time cluster bootstrap: Flux install, SOPS/age key, host Gitea
platform/ platform CONTROLLERS (Flux HelmReleases / operator bases): kyverno, cilium,
longhorn, external-snapshotter, cert-manager, externaldns, gateway, coredns,
vpn-egress, monitoring, cnpg, keycloak, oauth2-proxy, kubevirt
platform-config/ platform CONFIGS — the custom resources of the CRDs installed above
(ClusterIssuers, Gateway, Kyverno policies, KubeVirt/CDI CRs, Keycloak CRs).
Split out because CRs and the CRDs they use cannot apply in one pass.

Status
Roadmap phases 0–6 are delivered and deployed on the dev cluster; Phase 7 (prod) is not
open — clusters/prod is a design-only overlay.
| Phase | Delivered |
|---|---|
| 0 Foundations | ServiceDefinition schema + renderer, Kyverno L0 gate, conformance harness, CI |
| 1 Cluster bring-up | 3-node k3s HA on Proxmox VE (192.168.1.50/.51/.52), Cilium, Flux, SOPS |
| 2 Platform core | Cilium · Longhorn · cert-manager (LE-prod wildcard) · ExternalDNS · Gateway API · split-horizon CoreDNS |
| 3 Egress / VPN | ADR-0015 node-level OpenVPN split-tunnel + Cilium egress-gateway steering + host kill-switch |
| 4 Observability | kube-prometheus-stack · Loki · Alloy · Alertmanager. Velero still blocked on OQ-BKP; image-automation authored but disabled |
| 5 IaaS | KubeVirt + CDI on real nested KVM; live-migratable RWX VM storage. The UniFi VM runs, but UniFi OS Server is not yet installed in the guest |
| 6 Identity + CI | Keycloak (Operator + CNPG) · oauth2-proxy forward-auth · Grafana OIDC · kubectl OIDC SSO with group→RBAC · in-cluster Gitea Actions merge gate |
Conformance: 36 / 51 requirements covered (70.6%), 15 gaps, 1 safety-critical gap
(R-STATE-02, Longhorn node-loss). Regenerate with ./conformance/run.sh --coverage-only;
the full report is conformance/_artifacts/coverage/coverage.md.

Working on this repo
Everything the gate needs is baked into the pinned dev container — do not install the toolchain on the host:
infra/devcontainer/dev.sh build # once
infra/devcontainer/dev.sh run make -C ci gate # the same gate CI runs
infra/devcontainer/dev.sh # interactive shell (sops, flux, kubectl, tofu, ansible)
The container mounts the repo at /work, your age keyring, and the sibling spec repo read-only
so the spec-immutability check can actually run. See
infra/devcontainer/README.md.
A green run prints MERGE GATE: PASS. The L2/L3 conformance layers stay SKIPPED unless
CLUSTER_AVAILABLE=true — the static gate never pretends to have run them.
