Reported as "GET works, PUT/POST to add indexers fail, reloading never helps,
and I am never re-prompted". Diagnosis lands here; the MANIFEST FIX DOES NOT,
deliberately -- see the blocker below.
ROOT CAUSE, measured from two pods' logs interleaved to the second:
15:31:06 jackett [AuthSuccess]
15:31:29 radarr "cookie signature not valid, removing session"
15:31:32 jackett "No valid authentication in request" <- 3s later
Six oauth2-proxy instances (seven pods) emit the DEFAULT cookie name
`_oauth2_proxy` on `.home.keithjackson.dev` holding seven DIFFERENT
cookie-secrets (compared in-cluster by sha256; all distinct). `removing
session` is ClearSession, which expires the cookie on radarr's own zone-wide
--cookie-domain, so jackett's session is DELETED by a process in another
namespace, 26s after a clean login whose `expires` was 5 minutes out. 8 such
lines in radarr's log, 1 in jackett's, 0 elsewhere. It was never expiry and it
was never Jackett -- and it is why reloading does not help: the operator's
Radarr tab re-clears the cookie seconds after each new login.
Two contributing mechanisms, also measured:
* session lifetime == Keycloak access-token lifetime, 300.000s exactly, with
refresh_token:true on the same line and --cookie-refresh unset (default 0).
* XHRs answered 302 not 401: oauth2-proxy's AJAX guard needs an exact
`Accept: application/json`, which Jackett's jQuery does not send. On /api/
paths: 33 x 302 vs 2 x 401. A browser following a 302 re-issues a POST as a
GET and DROPS THE BODY -- 4 of 6 POSTs never reached Jackett at all.
WHY NO MANIFEST FIX HERE. apps/wave-0/jackett.yaml is a GENERATED GOLDEN. The
sidecar args come from one shared function, _oauth2_sidecar_container() in
catalog/render.py; catalog/jackett.yaml declares only auth.mode/auth.groups and
the auth schema is additionalProperties:false, so there is NO per-app override
hook. Hand-editing the rendered file is rejected by the gate exactly as
designed ("GOLDEN DRIFT ... render-golden: FAIL"). Changing the renderer
instead rewrites all five rendered apps -- measured:
CHANGED: apps/wave-0/{jackett,pihole,qbittorrent}.yaml
CHANGED: apps/wave-1/{radarr,sonarr}.yaml
and render-golden requires all five be regenerated in the same commit. Four of
them are owned by fix/oauth2-proxy-cookie-collision-fleet right now. The cookie
fix is ONE change, not five; it needs re-cutting as a single renderer commit
rather than two branches rewriting the same generated block.
Validated the intended argument list against the pinned image and the real
issuer before stopping: it printed back `name:_oauth2_proxy_jackett ...
domains:jackett.home.keithjackson.dev ... refresh:after 2m30s` and
`API route - Path: ^/api/`. Two corrections fell out of that: --api-route is
SINGULAR (--api-routes does not exist and the proxy refuses to start), and
--session-cookie-minimal is mutually exclusive with --cookie-refresh
("cookie_refresh > 0 requires oauth tokens in sessions"), so dropping
--pass-access-token does NOT shrink the cookie -- it is a least-privilege
change, not a size one.
Adds runbooks/oauth2-proxy-session.md: the four sidecar log lines that tell the
auth layers apart (including the upstream `-` that means the proxy answered a
request the app never saw), the cross-log collision diagnosis, and the
generated-golden warning with its blast radius. Registered in the
configMapGenerator AND runbooks/README.md so the URL resolves.
Jackett is NOT fixed by this commit and will keep losing its session to Radarr
until the renderer change ships.

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.
