Reported as "users cannot connect to Bedrock on UDP 19132". Measured read-only on prod; the platform delivered the packets and the server never opened the socket. Server `K3s-Bedrock` (c5837301-..., type=minecraft-bedrock, server_port=19132) exists and `./bedrock_server` is alive, but /proc/net/udp and /proc/net/udp6 in the crafty container hold NO socket on 19132 (0x4ABC) in either family -- port 19132 is bound as TCP (/proc/net/tcp6 ...:4ABC state 0A). Cause, from the server's own server.properties: transport=nethernet, the value Microsoft's BDS archive ships. Its inline docs: `Allowed values: "raknet" or "nethernet"`, and against server-portv6, `This property is ignored when transport=nethernet`. NetherNet is the WebRTC/Xbox-signalled transport and opens no RakNet UDP listener. Crafty does not manage the property (no `transport` anywhere under /crafty/app/classes/) and its only Bedrock probe is raknet_ping.py, hence commander.log spamming "Got timeout while issuing bedrock ping to 127.0.0.1:19132" -- over loopback, which indicts the server, not the network. The path below it is sound and was measured as such: crafty-l4-udp live as externalTrafficPolicy: Cluster with the VIP in status.loadBalancer, a non-empty EndpointSlice, `cilium-dbg service list` showing 192.168.2.22:19132/UDP => 10.0.0.130:19132/UDP (active) on BOTH announcing nodes, the datapath policy map carrying `Allow Ingress reserved:world 19132/UDP` with 26 packets / 27660 bytes already counted through it, pihole answering crafty-mc -> 192.168.2.22, and Flux at main@sha1:20ea70d == the GitRepository artifact. So this is not a platform or manifest defect. No manifest is touched: adding ports or widening policy for this would be manufacturing work. The repo-side defect is documentation -- the README told the operator that creating a server on 19132 was sufficient. README: add "Bedrock on UDP 19132 -- the transport trap" (the measurement chain, and the raknet_ping warning as its signature) and "Bedrock realities that are NOT platform defects" (no LAN/Friends discovery behind a VIP, consoles cannot enter an address, enable-lan-visibility collides with slots 1-2, server-portv6 is not exposed). Correct three stale claims: "the operator has not created any servers yet" (two exist), the human test implying a started Bedrock server is reachable, and the single-server Runtime state section (now a two-row table recording K3s-Bedrock's auto_start=0 / crash_detection=0 -- the create-API trap, live again, so it will not survive a pod restart). Also measured, reported, and deliberately NOT changed: the shared VIP's two leases sit on different nodes (crafty-l4-tcp on k3s-prod-3, crafty-l4-udp on k3s-prod-1), so two nodes ARP-announce 192.168.2.22. Benign under `Cluster` -- both nodes carry the full active frontend set -- and the existing L0 check l2-announced-vips-serve-from-any-node already forbids the `Local` that would make it fatal. A "shared VIPs must co-locate" check would assert runtime lease placement a static check cannot see. Read-only throughout: no apply/edit/patch, no flux reconcile, no write inside the container. Operator actions (set transport=raknet and verify the UDP bind; PATCH auto_start; tell players to Add Server by hand) are in the DECISIONS-LOG entry, along with what is UNVERIFIED -- chiefly that `raknet` fixes it is reasoned from the shipped docs, not observed.

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).

Status
Roadmap phases 0–6 are delivered, and Phase 7 (Production Readiness) is OPEN and in
progress. clusters/prod is no longer a design-only overlay: prod is the live cluster, serving the
apex home.keithjackson.dev. The dev cluster was decommissioned on 2026-09-12 (full migration:
dev out, prod onto the apex — see the DECISIONS-LOG), so phases 0–6 are now exercised on prod
hardware rather than on Proxmox VMs.
Phase 7 exit criteria — prod runs the same config via the prod overlay; DR proven; monitoring + alerts live:
| criterion | state |
|---|---|
| prod runs the prod overlay | met — 3× mini-PC bare metal, one Flux tree, prod overlay only |
| monitoring + alerts live | met 2026-09-13 — see the note below; this was not true before that date |
| DR proven | R-STATE-03 PROVEN on prod 2026-09-14 — off-cluster restore from Cloudflare R2. R-STATE-02 (node-loss) is still dev-only |
DR restore is proven on prod. R-STATE-03 reads proven in --status as of 2026-09-14 —
the first requirement in this repo to reach that state. Both of its verifiers are recorded:
dr-restore (L3, run 20260914T021505Z-24b8111, sentinel DR_RESTORED_FROM_OFF_CLUSTER_BACKUP_OK)
and placeholder-guard-coupling (L0). The L3 drill seeds a canary on the replicated longhorn
class, backs the namespace and volume data up off-cluster, destroys every in-cluster copy
(namespace, PVC and PV), restores into a clean namespace, and asserts the restored PVC binds a
different PersistentVolume — so an in-cluster survival cannot pass as a restore.
What remains for Phase 7: R-STATE-02 (node-loss) is still proven only on the decommissioned
dev cluster. That drill takes a real node down on a live cluster, so it is a deliberate, scheduled
exercise rather than something to run in passing.
Read --coverage-only and --status as two different questions; the earlier PROVEN: 0 was not a
bug but the honest answer, because proofs are claims about a specific tree on a specific cluster.
| Phase | Delivered |
|---|---|
| 0 Foundations | ServiceDefinition schema + renderer, Kyverno L0 gate, conformance harness, CI |
| 1 Cluster bring-up | 3-node k3s HA, embedded etcd, kube-vip VIP, Cilium, Flux, SOPS. Originally Proxmox VMs; now 3× mini-PC bare metal (k3s-prod-1/2/3, 192.168.2.10/.11/.12, k3s v1.36.4+k3s1, Debian 13) |
| 2 Platform core | Cilium · Longhorn · cert-manager (LE-prod wildcard) · ExternalDNS · Gateway API · split-horizon DNS, both halves: CoreDNS for pods, and PiHole as the authoritative LAN resolver for ${BASE_DOMAIN} on udp/53 + tcp/53 at a pinned VIP (192.168.2.23 on prod). The LAN half was claimed from the start but did not exist until 2026-09-14 — PiHole's Service was ClusterIP :80/:4180, so LAN clients ran on hand-maintained per-client dnsmasq files |
| 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 unblocked 2026-09-13 — backs up to Cloudflare R2 (OQ-BKP closed; the velero-plugin-for-aws tagging incompatibility needed a pinned plugin). Longhorn has no backup target by decision: volume data is protected by Velero + kopia to R2. 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 |
| 7 Production readiness | IN PROGRESS (DR restore proven 2026-09-14; node-loss outstanding). Prod live on bare metal serving the apex; dev decommissioned; CNPG HA 3 instances with primaries spread one per node; NFS bulk media + legacy Nextcloud mounted; VPN egress on prod. Alerting made real 2026-09-13 (Longhorn, cert-manager, Flux and twelve app SLIs had all been unable to fire). Open: node-loss (R-STATE-02) re-proven on prod. |
Conformance: 51 / 51 requirements covered (100%), 0 gaps, 0 safety-critical gaps (closed
2026-09-13; R-C2-01/R-C2-02 were the last two). Regenerate with
./conformance/run.sh --coverage-only; the full report is
conformance/_artifacts/coverage/coverage.md.
Coverage is not proof. A requirement is covered when an executable test exists for it, and
PROVEN only when a recorded run of that test is in conformance/runs/ledger.jsonl at the current
SHA on the cluster it claims. Read both numbers: --coverage-only for the first, --status for the
second.
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.
