The last steps of a prod bring-up were living in shell history: resume the tiers in the right order, clear a wedged HelmRelease, fix external-dns without deleting the other cluster's DNS. That is the same failure the Kyverno CRD pre-apply had, so it gets the same treatment. bootstrap/standup.sh — environment-agnostic (R-ENV-02), no dev/prod fork. Six idempotent steps: preflight, crds, unwedge, externaldns, resume, verify. THE GUARD IS THE POINT. --expect-server is MANDATORY and is compared against the live API server before any step runs; there is no override flag. Dev is live and shares the keithjackson.dev Cloudflare zone with prod, and on 2026-09-04 prod deleted every one of dev's public records. Negative control run: prod's kubeconfig with dev's server URL refuses and changes nothing. preflight fails closed if EXTERNALDNS_TXT_OWNER_ID is empty, still the base sentinel, or `default` (dev's owner) — the exact condition that caused the incident. It also surfaces SUSPENDED HelmReleases separately, because a suspended release keeps its last Ready condition and a stale `Ready=True` otherwise hides that Flux is not managing it at all (external-dns today). externaldns is the dangerous step, and the ordering IS the mitigation. A Helm upgrade resets replicas to 1 and applies new args in ONE operation, so there is no window to check the result first; if --txt-owner-id were missing the pod starts as owner `default` and syncs away dev's records. So the step PROVES THE OUTCOME BEFORE CAUSING IT: render the chart with the LIVE HelmRelease values and assert --txt-owner-id=<owner> appears, aborting if not. Rendering is deterministic and touches nothing, which turns a race into a precondition. Then snapshot Cloudflare, upgrade, re-verify live args (scale to 0 and fail if wrong), and diff the zone. resume walks the dependency order and STOPS at the first tier that does not go Ready — a partial understood bring-up beats a forced green. velero is skipped while S3_BACKUP_ENDPOINT is the TBD placeholder. TWO BUGS CAUGHT WHILE VALIDATING THIS, both by measuring instead of assuming: 1. preflight counted Kyverno CRDs with grep 'kyverno.io' and reported 20 of 22 — the policy-report types are in the wgpolicyk8s.io group. A preflight that under-reports reads as "the pre-apply failed" when it succeeded. Fixed and re-run: 22. 2. The documented node-health invocation used -e k3s_hosts=k3s_prod and SILENTLY RAN AGAINST DEV'S THREE NODES. Diagnostic plays deliberately keep their own target var (node_health_hosts, memattr_survey_hosts, vpn_egress_gateway_hosts) so they stay pointable while a bring-up is scoped elsewhere — a good design I did NOT change. The hazard is that the wrong flag does not error, it falls through to the dev default. Caught only by --list-hosts; the doc now leads with that warning and a dry-run command. Verified after fixing: node-health and all six site.yml plays target prod. .claude/settings.local.json — permission rules for the above. Every entry hardcodes prod's kubeconfig AND prod's --expect-server (or prod's ansible groups), so the permission strings are themselves prod-scoped and cannot be turned against dev. Deliberately NO rule for `dev.sh run bash -c *`, which would have been blanket cluster access wearing a narrow-looking mask. Refs R-ENV-02, R-GITOPS-01, R-SEC-02.

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.
apps/ application tier, reconciled as dependency-ordered WAVES:
wave-0/ wave-1/ wave-2/ rendered container apps (see DESIGN-waves.md)
vms/ KubeVirt VirtualMachines (non-gating tier)
catalog/ ServiceDefinition entries (the onboarding surface) + render.py
schemas/ ServiceDefinition JSON Schema + renderer contract
clusters/ Flux entrypoints + dev/ and prod/ overlays
conformance/ Chainsaw behavior/conformance suite + harness + coverage report
ci/ the gate as scripts (lint · schema · Kyverno L0 · L1 render · decision)
.gitea/ Gitea Actions CI running that gate on an in-cluster runner
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.
The running narrative — decisions, root causes, incidents, follow-ups — is
DECISIONS-LOG.md. It, not this table, is the authoritative record.
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.
