The fault is BOOT-TO-BOOT NON-DETERMINISTIC — the same machine booted correctly two boots
earlier — so it has to be detected on every health run, not diagnosed once. And node 1 is
exposed to the identical lottery on every reboot while currently looking healthy.
firmware.efi_memattr — reads the kernel ring buffer and distinguishes six states:
Failed to map EFI Memory Attributes table @ 0x.. -> FAIL (memory lost NOW)
Unexpected EFI Memory Attributes table version <N> -> WARN (corrupt table still published;
intact only by luck)
[Firmware Bug]: Corrupted EFI ... detected! -> PASS (the >=6.13 fix working)
no memattr line, log reaches early boot -> PASS (no table / accepted / not UEFI)
no memattr line, log does NOT reach early boot -> SKIP
dmesg unreadable -> SKIP
memory.physical_total — deliberately a SEPARATE check, not folded in: it measures the SYMPTOM
with no kernel log at all, so an unreadable-dmesg node is still not unmeasured. Two sub-verdicts,
worst wins: /proc/zoneinfo present-vs-managed (world-readable, works on metal and VMs — sum of
managed IS MemTotal) and MemTotal vs the DIMM total from dmidecode. Thresholds 10% WARN / 25%
FAIL, set from measured baselines: 2.0% prod-1, 2.1% workstation, 2.2% dev VM, vs 83.4% prod-2.
THREE GUARDS AGAINST A FALSE PASS, because "no memattr line" must never silently mean "fine":
1. dmesg failure yields available:false with the exact reason (rc, uid, kernel.dmesg_restrict) -> SKIP
2. the ring buffer WRAPS and every memattr line prints in the first fraction of a second, so the
collector records a boot_covered anchor (Linux version / BIOS-provided physical RAM map); no
memattr line WITHOUT that anchor is a SKIP, not a PASS
3. memory.physical_total needs no kernel log at all
Verified by forcing the unprivileged path: SKIP with the EPERM reason while zoneinfo still PASSed.
VERDICTS, confirmed live:
k3s-prod-1 WARN "EXPOSED, not immune ... survived only because its garbage version field read
1030, which is > 2 ... one unlucky boot from the failure state" + PASS 2.0%
k3s-prod-2 FAIL "THIS NODE HAS LOST MEMORY TO THE BUG ... at 0xbeeb0018" + FAIL 83.4%/83.6%
k3s-dev-* PASS both, NO false finding: "no UEFI config-table line ... did not boot via UEFI.
Log reaches back to early boot, so that absence is measured, not assumed."
Both failure texts carry the remediation verbatim, including that there is NO kernel cmdline
workaround because efi_memattr_init() runs before any efi= bail-out.
Root-gating follows the role's existing pattern: --privileged re-runs THE SAME collector under
become, only when the unprivileged pass actually failed to read something. Reimplementing the log
grep and SMBIOS parse in Jinja would have been a second source of truth for the same fact.
LATENT BUG FIXED in passing: the collector's run() used bare shutil.which(), so dmidecode (in
/usr/sbin) was invisible under the unprivileged k3s PATH and produced a FALSE "not installed"
skip reason. Now shares the sbin-aware which() collect_tools() already had.
INCIDENTAL FINDING recorded in §0b: node 1's DIMMs are NOT a matched pair — DIMM1 Micron
8ATF2G64HZ-3G2E1 (DDR4-3200), DIMM3 Micron 16ATF2G64HZ-2G6E1 (DDR4-2667). Both 16 GB so capacity
is right, but different rank organisation and rated speed, so the pair runs at 2667. Not a fault;
recorded because §2 requires the three nodes to end up symmetric and "2×16 GB Micron" hid it.
Serves: R-ENV-01, R-ENV-03, R-OBS-04. 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.
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.
