feat(prod): SOPS decryption (same age key as dev) + GitOps source on main

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.

+## 2026-08-30 — Upgrade campaign landed: cluster now k3s v1.36.4 / Debian 13 / Cilium 1.20.1 / Longhorn 1.12.1
+
+The platform-wide upgrade campaign completed and is live. Verified current state of the dev cluster:
+
+- **k3s v1.36.4+k3s1** (was v1.31.5+k3s1), 3-server embedded-etcd HA.
+- **Debian 13 (trixie)** node OS (was Debian 12 bookworm).
+- **Cilium 1.20.1** (was 1.16.5); **Gateway API v1.6.1** (was v1.2.x).
+- **Longhorn 1.12.1** (was 1.7.3).
+- cert-manager >=1.21; Velero chart 12.x / Velero v1.18; kube-prometheus-stack 88 (operator
+  v0.93.1, Grafana 13.2.0); kube-vip v1.2.3.
+- Node RAM **24 GiB / 24576 MB** (tofu default; earlier docs said 16 GiB).
+- Each node now carries a **dedicated virtio2 SSD etcd disk** (`/dev/vdc`, `local-zfs`) isolating
+  etcd WAL fsync from HDD Longhorn I/O — see `docs/plans/ssd-etcd-isolation.md`.
+
+**The "LIVE STATE VERIFIED 2026-08-26" line above (k3s v1.31.5) is SUPERSEDED by this entry.**
+That older line is retained as historical record — this append is the current source of truth.
+Documentation and comments across the repo were reconciled to these facts in the same change;
+toolchain kubectl bumped 1.31.4 → 1.36.4 (the 1.31 pin exceeded the ±1 version skew against a 1.36
+cluster). Revalidation items deliberately left open: external-snapshotter v8.2.0 pin vs 1.36, the
+Cilium ext_authz/forward-auth workaround relevance under 1.20.1, and the conformance ImageVolume
+feature-gate assertions under 1.36.
+
+## 2026-08-31 — Post-upgrade stabilization: SSO fixed, all UIs gated, 8 vCPU, CI live. **PM HANDOFF.**
+
+Everything the 08-30 campaign deferred is resolved; the platform is fully green. **This entry is the
+current source of truth and the handoff for the next PM.** (Session ran on a different workstation; a
+fresh agent should read this entry + `infra/PHASE1-STATUS.md` + `docs/plans/` and start at Next Steps.)
+
+### LIVE STATE (verified 2026-08-31, all green)
+- 3× k3s **v1.36.4+k3s1**, Debian 13, **8 vCPU / 24 GiB** each (raised from 6 — see #5). Proxmox host 24 cores, ~idle.
+- Cilium 1.20.1 (GW-API v1.6.1), Longhorn 1.12.1, cert-manager 1.21, Velero chart 12/v1.18, kube-prometheus-stack 88
+  (Grafana 13.2), kube-vip v1.2.3, **Loki chart 7.x / v3.6.11**, **Kyverno chart 3.9 / v1.19** (the last two were the
+  08-30 "deferred" items — now done). etcd on the dedicated SSD virtio2 disk per node.
+- All Flux kustomizations + HelmReleases Ready; 0 not-ready pods.
+- **SSO end-to-end**: native OIDC for grafana/gitea/nextcloud/semaphore/headlamp; the 5 forward-auth UIs
+  (pihole/jackett/qbittorrent/radarr/sonarr) gated by per-app oauth2-proxy sidecars (fail-closed, 302→Keycloak).
+  Platform-admins require TOTP MFA.
+- **Gitea Actions CI is LIVE + enforcing**: `.gitea/workflows/gate.yml` runs `make -C ci gate` on push/PR to main;
+  required status check; runner `incluster-dind` online (ns gitea-actions).
+
+### What changed this session (durable)
+1. **SSO cluster-wide break→fix — root cause Cilium CVE-2025-30162.** The 1.16→1.20 security fix makes the shared
+   Gateway L7 proxy (`enforce_policy_on_l7lb`) re-check a pod's egress policy against Keycloak's REAL backend
+   identity on the split-horizon hairpin; `toEntities: world` no longer covers it → all app SSO 403'd
+   ("Access denied", `server: envoy`). Fix: explicit `toEndpoints` egress allow to the keycloak backend —
+   `catalog/render.py` emits it for `auth.mode ∈ {oidc,forward-auth}`; headlamp/crafty hand-written. (68690e5, 8a424bc)
+2. **Keycloak MFA config bug**: browser-mfa conditional-OTP used a non-existent config key → "Invalid role name: null"
+   → 403 for every platform-admin login. Fixed to `condUserRole: platform-admin` in git + live via kcadm. (45deac9)
+3. **VPN egress restored**: the Debian 12→13 re-provision wiped k3s-dev-3's node-host OpenVPN (PIA); re-ran
+   `vpn.egress.gateway.yml`. Re-provision runbook (infra/ansible/README.md) updated — node-host roles (k3s, kube-vip,
+   vpn.egress.gateway) must be re-run after any reprovision.
+4. **Grafana OOM** (kps 65→88 ships Grafana 13) — the hidden blocker that stalled the whole kps upgrade + platform
+   tier. limits 256→512→768Mi; Prometheus 2→3Gi. (b2b1aa5 and follow-ups)
+5. **Node vCPU 6→8** — steady CPU PSI was 15-23% / load at-or-over core count (no spike headroom); now PSI ~4.5-7.7%.
+   bpg reboots the VM on a cores change → rolled ONE node at a time, waiting Longhorn healthy between. (676c37a)
+   + node CPU PSI/load alerts + a "Nodes — CPU/Memory Pressure" Grafana dashboard. (a720c73)
+6. **Security: 5 forward-auth UIs gated** with per-app oauth2-proxy sidecars (Option B, crafty's proven pattern) +
+   per-app Keycloak clients + SOPS creds. Closes the un-gated-admin-UI exposure. (72d4720, b2752ae)
+7. **Gitea Actions CI finished**: `ci/touched-requirements.sh` now excludes comment-only R-ID prose, so the workflow
+   runs the exact aggregate `make -C ci gate`. (27bc024)
+8. **external-snapshotter vendored** — was remote github kustomize bases; the kustomize-controller's per-reconcile
+   `git fetch github.com` flaked past its 27s timeout → `BuildFailed` stalled the platform tier. Now local
+   `crds.yaml` + `snapshot-controller.yaml` (offline, deterministic build). (7a79cea)
+9. **08-30 revalidations closed**: ImageVolume gate is now ON in 1.36 → conformance rationale comments corrected
+   (d60e553); external-snapshotter v8.2.0 pin kept (CRDs served at v1, works on 1.36); Cilium native ExternalAuth
+   evaluated → **DEFER** (see plan).
+
+### Operational gotchas that STILL matter (for the next PM)
+- **Access**: `./infra/devcontainer/dev.sh run <cmd>` (kubectl/flux/helm/tofu/ansible/kcadm). Do NOT run `dev.sh`/`make
+  gate` concurrently — execs into the one container interfere → transient failures, just retry. Deploy = `git push
+  gitea main` → Flux. Gate before push: `dev.sh run make -C ci gate` → "MERGE GATE: PASS".
+- **NAT topology** (see PHASE1-STATUS): API via `192.168.2.50:6443`→VIP .1.49; node SSH `192.168.2.102:225X`;
+  Proxmox API `192.168.2.102:8006`. A single node reboot can briefly drop the kubeconfig NAT — wait ~3 min for boot.
+- **Keycloak realm import is ONE-SHOT**: the operator logs "Job already executed - not recreating" — a git change to
+  `keycloak-realm-import.yaml` does NOT re-import. Edit the live realm via `kcadm.sh` in keycloak-0 (admin creds:
+  secret `keycloak-admin-credentials`; kcadm present, curl/python3 are NOT), AND fix git for reproducibility.
+- **Cilium world-hairpin (CVE-2025-30162)**: any in-cluster→`*.home` call hairpins through the Gateway and gets its
+  egress re-checked against the DESTINATION's real cluster identity — `toEntities: world` won't cover it. render.py
+  handles the keycloak case for SSO apps; a NEW app→app-by-hostname dependency needs an explicit `toEndpoints` allow.
+- **Remote github kustomize bases flake** (27s git-fetch timeout). external-snapshotter is now vendored;
+  **platform/kubevirt still uses remote bases** — vendor it the same way if it `BuildFail`s.
+- **Longhorn on the HDD**: every node reboot degrades all 18 volumes → full rebuild (slow; 30%+ Proxmox IO-delay).
+  Roll reboots one node at a time; wait `robustness=healthy` before the next. Fix = `docs/plans/longhorn-ssd-tiering.md`.
+- **Gitea** can go read-only (ext4 remount-ro) during node churn → `kubectl -n gitea rollout restart deploy/gitea`.
+
+### NEXT STEPS (prioritized) — where to start
+1. **Longhorn → SSD hot-tier move** — `docs/plans/longhorn-ssd-tiering.md`. The "won't fit" blocker was a measurement
+   artifact (working set ~79 GB; SSD ~323 GB free). Moving the hot tier (Prometheus/CNPG DBs/Loki/Gitea ≈ 51 GB) off
+   the HDD removes the reboot-rebuild tax on every future maintenance op. **Highest-leverage infra item.** Pre-flight:
+   re-verify live SSD free + read HDD SMART.
+2. **L2/L3 conformance in CI** — `docs/plans/l2-l3-conformance-ci-wiring.md`. Needs the trigger-credential decision
+   (scoped in-cluster SA + Kyverno-pinned Job shape; never a broad kubeconfig in CI). The gate runs no-cluster stages today.
+3. **Forward-auth long-term** — `docs/plans/cilium-native-externalauth-evaluation.md` (DEFER now: experimental CRD
+   channel + fail-open history). The 5 UIs are safely sidecar-gated in the meantime.
+4. **Remaining Phase-6 onboarding** — see DESIGN-waves.md / `catalog/` (services rendered-but-not-onboarded).
+5. **Vendor platform/kubevirt** remote bases proactively (same flake class as #8).
+6. **Human action**: finish Headlamp login = complete TOTP enrollment in the browser.

+## 2026-08-31 — **PHASE 7 OPENED (prep only)**: first prod node on the bench
+
+The operator added the first **production** node and opened roadmap Phase 7. This entry records the
+opening, the state of the hardware, the operator's three decisions, and the blockers that stand
+between "a node exists" and "prod reconciles from `clusters/prod`".
+
+### Governance — Phase 7 entry gate, recorded not waived
+
+`roadmap/phases.md` gates Phase 7 on **two** conditions: *"Phases 1–6 proven in dev/test; operator
+declares prod hardware ready."* The operator has declared hardware ready. **The first condition is
+not met** — conformance is 37/51, and the uncovered set includes **R-ENV-01/02/03**, the exact
+requirements prod provisioning serves. We proceed with *prep only* on that basis, with no prod
+install until the §7 repo blockers close and the gate is green. This is an accepted, explicit risk,
+not an oversight.
+
+### Node 1 as-found (`192.168.2.10`, verified by SSH 2026-08-31)
+
+Not blank — imaged and reachable. **HP EliteDesk 800 G5 Desktop Mini** (matches the spec's `3× mini-PC
+bare metal`), i7-9700T 8c/8t, **31 GiB RAM**, Debian 13 trixie / kernel 6.12, hostname already
+`k3s-prod-1`, `k3s` user reachable with the `home_network` key, VT-x + `/dev/kvm` present
+(KubeVirt-capable), k3s not installed. Firmware HP R21 Ver. 02.26.00.
+
+**One 477 GB SATA SSD** (`C400-MTFDDAC512M` — a ~2011-era Micron/Crucial consumer drive) carrying
+everything: `/` 30G, `/var` 12G, swap, and `/srv` 433G. No second device. Dev, by contrast, runs two
+dedicated data disks per node (Longhorn + a dedicated SSD for etcd, added after HDD contention
+starved etcd WAL fsync).
+
+### Operator decisions (2026-08-31)
+
+1. **Phase 7 opens, prep work only** — repo work and node baselining now; no k3s install until the
+   parameterization blockers land and the gate is green.
+2. **Wait for all three nodes before `cluster-init`** — prod comes up as spec-conformant 3-node HA
+   embedded etcd on day one; no single-server-etcd window, no later member-add.
+3. **Check drive health before choosing the disk layout** — a 15-year-old consumer SSD is not an
+   obvious home for prod state.
+
+### Findings — prod would build WRONG today
+
+1. **R-ENV-02 is violated in the base (the headline blocker).** The overlay model promises dev and
+   prod differ *only* by `cluster-vars` values. In fact dev LAN addresses are hardcoded into base
+   manifests: `k8sServiceHost: 192.168.1.50` (`platform/cilium/helmrelease.yaml:50` + the
+   `values.yaml` mirror), the Cilium LB pool `192.168.1.53-.60`
+   (`platform-config/cilium/l2-ip-pool.yaml`), crafty `.55`, the UniFi VM `.54`, and three S3 backup
+   endpoints at `192.168.1.9:9000`. **Prod is on `192.168.2.x` — none of these follow.** Fix is to
+   tokenize each into a `cluster-vars` knob and set it in both overlays; the `postBuild.substituteFrom`
+   seam already exists on every relevant Kustomization. Note `platform/cilium/values.yaml` is only a
+   *reference mirror* — the authoritative pair is the HelmRelease (Flux) and the Ansible j2 template
+   (already parameterized), so the Ansible side needs no change.
+2. **`clusters/prod` never sets `GATEWAY_VIP`** → it would inherit the base default `10.73.0.240`,
+   an address on the **retired libvirt network**. `cluster-vars`' own comment flags this as owed
+   "when hardware is built".
+3. **Sudo on node 1 requires a password** — every Ansible playbook fails at its first `become`.
+   **Operator ruling: prod does NOT get NOPASSWD sudo** (my initial recommendation to mirror dev was
+   rejected, correctly — dev's passwordless sudo is a convenience that should not propagate to
+   prod). Instead prod uses Ansible `become` with an **ansible-vault-encrypted**
+   `ansible_become_password` in `inventory/group_vars/k3s_prod/vault.yml`, mirroring the existing
+   `hypervisor` and `proxmox_hosts` groups; the decrypting passphrase stays outside the repo at
+   `~/.config/home-k3s/ansible-vault-pass`. Plays still run unattended, no plaintext secret in git,
+   and prod keeps a real sudo boundary.
+4. **`node_baseline` device defaults are virtio** (`/dev/vdb`, `/dev/vdc`) and do not exist on bare
+   metal; the role makes a filesystem on a *block device*, so a single-disk node needs either a
+   second drive, `/dev/sda5`, or a repartition. Prod `group_vars` must override.
+5. **Single upstream resolver on node 1** (`192.168.2.1`) — the same SPOF class that broke
+   containerd pulls and CoreDNS forwarding on dev. The fix is **stranded unmerged** on
+   `fix/node-dns-resilient-upstream`.
+
+### RESOLVED BY OPERATOR — status comes from the repository, not the task board
+
+I raised an escalation here: `AGENTS.md` §11 designates `agents/task-board.md` as the one surface
+agents may edit, yet `ci/spec-immutability.sh` fails the merge gate on **any** spec-repo dirt with no
+path exception, and committing the board there moves spec `HEAD` off `ci/SPEC_PIN` — which also
+fails. Editing the board as instructed blocks every merge. That is why the board still reads
+all-`todo` after six delivered phases.
+
+**Operator ruling (2026-08-31): the task board is not the status surface. The repository is.**
+Status of each requirement/spec is to be *derived from the state of the repo* — what is authored,
+what is reconciled, what has a green requirement-tagged test — not from a hand-maintained board.
+
+Consequences, adopted:
+- The spec board is left alone. It is a historical seed, not a live surface. No agent edits it, and
+  no `SPEC_PIN` churn is spent keeping it current.
+- `ci/spec-immutability.sh` keeps its full strictness — **no path exception was added**. Weakening
+  an R-TEST-06 gate to make a bookkeeping file writable would have been a defect, not a fix.
+- The **repo-derived spec status report** becomes the artifact of record, alongside the existing
+  requirement-coverage report and this log. Coverage already answers "does a tagged test exist";
+  the status view must also answer "is this requirement actually *implemented and reconciled* in
+  the repo as it stands".
+
+### Next steps
+
+1. **Operator:** configure NOPASSWD sudo on `k3s-prod-1`, then capture `smartctl -a /dev/sda`
+   (commands in `infra/PROD-PROVISIONING.md` §5). The disk decision waits on that output.
+2. **Land the R-ENV-02 tokenization** — the critical path for prod reconciling at all. Dev overlay
+   must set every new knob to today's exact value so live dev sees zero drift (`make -C ci render-golden`).
+3. **Complete `clusters/prod`** — `GATEWAY_VIP`, the L2 pool, and the prod backup target.
+4. **Land the two stranded fix branches** (`fix/node-dns-resilient-upstream`,
+   `fix/act-runner-dind-readiness`) — the DNS one now matters for prod too.
+5. Resolve the task-board escalation above.
+6. Nodes 2 and 3 through `infra/PROD-PROVISIONING.md` §1–§5 as they arrive.

+## 2026-08-31 — CI is the enforcement point; the LOCAL gate produced a FALSE GREEN
+
+**Operator directive: "Conformance and gates are enforced at the gitea runner and CI/CD level.
+Use it."** Adopted. The authority on whether a change is mergeable is the Gitea Actions run, not a
+local `make -C ci gate`. Local runs are a fast pre-check only.
+
+This was proven immediately and expensively. Branch `docs/phase-7-open-prod-node-1`:
+
+- **Local** `make -C ci gate` → `no changed files vs base; empty touched-requirement set` →
+  **MERGE GATE: PASS**.
+- **CI**, same commit (`a1fb31a`, task 200) → 17 touched requirements correctly computed →
+  `REQUIRE: FAILED — required requirement(s) uncovered: ['R-SEC-01','R-SEC-02','R-TEST-06']` →
+  **MERGE GATE: BLOCKED**.
+
+The local run resolved an empty diff base and therefore checked nothing, reporting green. **A local
+false green is the most dangerous failure mode this project has** — it hid real coverage debt from
+the PM and would have hidden it from any future agent. `ci/touched-requirements.sh` base-ref
+resolution is being fixed so local agrees with CI, or announces loudly that it cannot determine a
+base. An honest noisy skip beats a quiet false pass (`ci/README.md` exit-code contract).
+
+The gate itself was RIGHT: we authored a vaulted-secret flow (R-SEC-01) and status tooling that
+reasons about spec immutability (R-TEST-06) while those requirements had **no covering test at
+all**. Tests are being authored rather than the rule being narrowed.
+
+**How to read CI from a workstation** (the API paths are non-obvious, so recording them):
+```bash
+CRED=$(printf 'protocol=https\nhost=gitea.home.keithjackson.dev\n\n' | git credential fill)
+# list recent runs (id | workflow | branch | status | sha):
+curl -sk -u "$U:$P" "$B/api/v1/repos/Home-Network/home-network-k3s-impl/actions/tasks?limit=10"
+# fetch a task's log — NOTE the job-id/task-id OFFSET: task N is at jobs/(N+5)/logs on this instance
+curl -sk -u "$U:$P" "$B/api/v1/repos/Home-Network/home-network-k3s-impl/actions/jobs/205/logs"
+```
+`.../actions/runs/<run>/jobs` is 404 on this Gitea version; use `actions/tasks` + `actions/jobs/<id>/logs`.
+
+### OPERATOR ATTESTATIONS (2026-08-31) — capability vs. automated proof
+
+The operator states, and this log records as fact:
+
+1. **DR is PROVEN** — Velero backups to the Proxmox server, restore demonstrated. R-STATE-03's
+   capability is delivered and in operational use.
+2. **Cluster resilience is PROVEN at the dev-cluster level** — node loss / rebuild demonstrated.
+   It is slow because Longhorn storage is on HDD (etcd is the exception, on its dedicated SSD),
+   which is a performance property, not a correctness gap.
+
+**Distinguish capability from automated proof.** The new repo-derived status report flags
+`R-STATE-03` as a safety-critical requirement whose L3 test body asserts nothing. That finding
+stands and is NOT contradicted by the attestation above — it is **test debt, not capability debt**.
+The system does the thing; the suite does not yet assert that it does. Per the project's own
+definition of done, only a green requirement-tagged test is acceptance — so the remaining work is
+to make `dr-restore/chainsaw-test.yaml` and the node-loss test actually assert the behaviour the
+operator has already demonstrated, and let the runner enforce it. Recording the attestation here
+does not close the requirement, and the gate must not be softened to make it appear closed.
+

+
+## 2026-09-01 — Phase-7 prep session complete. **PM HANDOFF.**
+
+Everything below is on branch `docs/phase-7-open-prod-node-1` / **PR #4**, 13 commits, the
+enforced Gitea gate **green**. Nothing has been installed on prod hardware. `main` is untouched
+until the operator merges.
+
+### Delivered
+1. **Phase 7 opened (prep only)** with the entry-gate shortfall recorded, not waived.
+2. **T-7.1 checklist** (`infra/PROD-PROVISIONING.md`) written against the real hardware.
+3. **R-ENV-02 tokenization** — 6 `cluster-vars` knobs; prod would otherwise have come up
+   announcing DEV addresses. Dev proven byte-identical.
+4. **Prod Ansible**: inventory, vaulted `become` (prod gets NO passwordless sudo), and
+   **target-group parameterisation** so prod reuses the roles unchanged.
+5. **`node_health` role** — read-only, portable dev+prod, run against both.
+6. **Repo-derived spec status report** (`run.sh --status`).
+7. **CI false-green killed** + L0 static tests for R-SEC-01/02 and R-TEST-06.
+8. **dind readiness fix**; **DNS resilience re-authored** for the current stack.
+9. **`dr-restore` now asserts** — safety-critical scaffolds 0.
+
+### Numbers
+Coverage 37/51 → **40/51**. Executable tests 32 → **36**. Scaffold-only 5 → **4**.
+Safety-critical without an executable L3 1 → **0**. **PROVEN: 0 — still not derivable**, by
+design; proof-of-pass is not recoverable from repo state, so a green-run ledger is the only
+thing that ever closes a requirement.
+
+### Corrections made during the session (recorded so they are not re-litigated)
+- **NOPASSWD sudo on prod: REJECTED** by the operator. Prod uses vaulted `become`. My original
+  checklist copied dev's convenience onto prod; that was wrong.
+- **The "`$i` envsubst bug" was FALSE.** An assessment claimed Flux envsubst ate bare `$i`,
+  making the dind cert-wait bound a no-op. Running the real `flux envsubst` disproved it: bare
+  `$VAR` passes through; only `${VAR}` expands — matching this repo's own contract in
+  `clusters/base/apps-vms.yaml`, itself written after empirical probing. **No escaping was
+  applied**; `$${i}` would have been an active regression (correct only on the envsubst path —
+  on a plain `kustomize build`, `sh` reads `$$` as its PID). Agent reports are not evidence;
+  the tool is.
+- **The stranded DNS branch was NOT landed.** Its netplan mechanism no longer exists on Debian
+  13; landing it would have broken `node-baseline.yml` on every node.
+
+### Near-misses worth remembering
+- A YAML **comment** nearly broke every merge in the repo: Flux envsubst runs over comments too,
+  so a braced name with punctuation is a fatal parse error that fails the whole `apps-wave-1`
+  Kustomization.
+- `roles/cilium`, `cluster_verify`, `flux_bootstrap` all hardcoded `.cache/dev.kubeconfig` — the
+  file `dev.sh` exports as `$KUBECONFIG`. The moment prod became targetable, a prod run would
+  have silently overwritten it and left the operator's `kubectl` answering from **prod**.
+- Prod's `GATEWAY_VIP` outside the LB pool would have brought the Gateway up on `.21` while
+  split-horizon DNS answered `.20` — blackholing in-cluster SSO while reporting healthy.
+
+### BLOCKED ON THE OPERATOR — nothing else moves without these
+1. **Create `inventory/group_vars/k3s_prod/vault.yml`** (`ansible_become_password`). The
+   passphrase file already exists. This gates SMART, the packages-only baseline, and every
+   future prod play.
+2. **Drive health decision** — run `smartctl -a /dev/sda` once `smartmontools` lands via
+   `node-baseline.yml -e k3s_hosts=k3s_prod --tags packages`. Prod state on an unmeasured
+   ~2011 consumer SSD is the open risk.
+3. **Prod's second DNS upstream** — `192.168.2.1` is both gateway and only IPv4 resolver.
+4. **Prod backup target** — `S3_BACKUP_ENDPOINT` is still `TBD-PROD-*`; dev's versitygw is on
+   the far side of the pfSense boundary.
+5. **`UNIFI_L4_VIP` / `CRAFTY_L4_VIP`** — allocatable from `.20-.30`, not invented here.
+6. **Merge PR #4.**
+
+### Known, documented, NOT fixed
+- `roles/flux_bootstrap` shells to `bootstrap/flux/bootstrap.sh` with a hardcoded
+  `--path=clusters/dev` — retargeting prod needs a `bootstrap/` change.
+- Prod has no VPN egress group (needs its own vaulted PIA credentials).
+- **`dr-restore` is AUTHORED, NEVER EXECUTED** (`conformance.home.k3s/never-executed`). It is
+  destructive; converting it to proven needs an operator maintenance-window run. The log must
+  show `DR_RESTORED_FROM_OFF_CLUSTER_BACKUP_OK`, **not** `DR_RESTORE_SKIPPED_OK` — green but
+  proving nothing.
+- `dind` → native sidecar `initContainer` with a `docker info` startupProbe (NOT a bare
+  tcpSocket probe) is the right shape on k3s 1.36; deferred so a merge-gate failure is
+  unambiguous.
+- **Non-ECC RAM — RISK ACCEPTED by the operator (2026-09-01), not an open item.** `node_health`
+  correctly reports ECC status as unknowable (no EDAC controller bound). Operator rationale:
+  this is a 3-node k3s homelab, not enterprise k8s; corruption on one node is outweighed by the
+  other two and results in node ejection. That holds for the dominant failure mode — etcd raft
+  (per-entry CRC + boltdb page checksums, quorum of 2 survives) and Longhorn (3 replicas, hard
+  anti-affinity, rebuild from healthy peers) both detect a *divergent* node and eject/rebuild it.
+  The residual it does not cover is corruption introduced *upstream* of replication: bytes
+  corrupted before the checksum is computed replicate faithfully to all three replicas, so
+  quorum sees no disagreement. Low probability, and the mitigation (ECC hardware) is out of
+  scope for this platform. **Do not re-litigate.** The one thing that operationalises the
+  operator's own argument is Longhorn's `snapshotDataIntegrity`, which is currently left at the
+  chart default rather than set explicitly — see the follow-up in `platform/longhorn/`.
+- L2/L3 conformance still SKIPs in CI (`docs/plans/l2-l3-conformance-ci-wiring.md`); it needs
+  the trigger-credential decision — a scoped in-cluster SA, never a broad kubeconfig in CI.
+

+
+## 2026-09-01 — INCIDENT: merging PR #4 briefly broke Cilium on 2/3 dev nodes. **Root cause: a substitution race that fails OPEN.**
+
+Merging the R-ENV-02 tokenization (PR #4, `dce0e8f`) triggered a Cilium Helm upgrade that put
+`cilium` agents into `Init:Error` on `k3s-dev-1` and `k3s-dev-2`. It **self-healed in ~6 minutes**
+and the cluster is fully green (12/12 Kustomizations Ready, 0 HelmReleases unready, 0 pods down).
+Recording it because the mechanism is systemic, will recur, and is far more dangerous on a cold
+prod bootstrap than it was here.
+
+### What happened
+
+The HelmRelease config digest tells the whole story:
+
+```
+v8   05:49:39  digest e83bf695…      <- before
+v9   05:50:11  digest eebd6c88…      <- the bad render
+v10  05:55:23  digest e83bf695…      <- identical to v8 again
+```
+
+The config changed and then changed **back to byte-identical**. Nothing in git differed
+semantically — `git diff` over `platform/cilium/helmrelease.yaml` shows only comments plus
+`k8sServiceHost: "192.168.1.50"` → `k8sServiceHost: "${K3S_API_HOST}"`, and the dev overlay sets
+`K3S_API_HOST=192.168.1.50`. The pre-merge byte-identity verification was **correct**; the steady
+state is identical. The damage happened in a transient intermediate state.
+
+### Root cause — the var and its consumer are reconciled by DIFFERENT Kustomizations
+
+- `cluster-vars` (which *defines* `K3S_API_HOST`) is owned by the **`flux-system`** Kustomization.
+- `platform/cilium/helmrelease.yaml` (which *references* it) is owned by the **`platform`**
+  Kustomization, via `postBuild.substituteFrom: cluster-vars`.
+- There is **no dependency ordering between defining a variable and using it.**
+
+So there is a window where `platform` renders the NEW manifest against the OLD `cluster-vars`,
+which has no `K3S_API_HOST` key yet. **Flux's post-build substitution is non-strict by default: an
+undefined variable becomes the EMPTY STRING, silently.** That produced `k8sServiceHost: ""`, Helm
+upgraded Cilium with it, and the agents fell back to the in-cluster ClusterIP `10.43.0.1:443` —
+which only the Cilium agent itself can translate. The agent was the thing restarting, so its own
+`config` init container could not reach the API server:
+
+```
+level=error msg="Unable to contact k8s api-server" ipAddr=https://10.43.0.1:443
+  error="dial tcp 10.43.0.1:443: i/o timeout"
+level=fatal msg="Build config failed"
+```
+
+Once `flux-system` applied the updated `cluster-vars`, the next `platform` reconcile rendered the
+correct value, digest returned to `e83bf695…`, and all three agents came up.
+
+`optional: false` on the `substituteFrom` entry does **not** protect against this — it only requires
+the ConfigMap to *exist*, not that every referenced key is defined.
+
+### Why this matters much more for prod
+
+On dev, one Cilium agent (`k3s-dev-3`) stayed up throughout, the API server was reachable, and the
+race closed on its own. **On a cold prod bootstrap every one of these knobs is new simultaneously**,
+there is no already-running CNI to fall back on, and an empty `k8sServiceHost` means Cilium may
+never come up at all — with no healthy peer to recover from. This is a plausible
+bring-up-blocker for `clusters/prod`.
+
+### The fix — make substitution FAIL CLOSED
+
+`kustomize-controller` currently runs with **no** `--feature-gates` argument, i.e. non-strict
+substitution. Flux supports `StrictPostBuildSubstitutions`, which makes an **undefined variable fail
+the Kustomization** instead of silently emptying it. That is exactly this project's stated doctrine
+("if unsure, deny/close"; "never fake green") applied to the substitution layer, and it converts
+this entire bug class from *silently corrupt a critical value* into *a loud, blocking reconcile
+failure*.
+
+**Not enabled unilaterally** — turning it on cluster-wide would immediately fail any Kustomization
+that references a variable not defined in `cluster-vars`, including legitimate shell `${…}` in
+embedded scripts. The safe sequence, before flipping it:
+1. Enumerate every `${VAR}` in every substituted path and prove each is either defined in
+   `cluster-vars` or correctly escaped as `$${VAR}`.
+2. Then enable the gate, and let CI + a dev reconcile prove it.
+
+Interim discipline, independent of the gate: **add a `cluster-vars` knob in one commit and
+reference it in a later one**, so the definition is always reconciled before its first use.
+
+### Operational note worth keeping
+
+A Cilium rolling upgrade on this cluster is not risk-free even when the values are right: the
+`config` init container resolves the API server through the ClusterIP unless `k8sServiceHost` is
+set, and the agent that translates that ClusterIP is the one being replaced. Keep
+`k8sServiceHost`/`k8sServicePort` correct at all times, and roll Cilium one node at a time.
+
+---
+
+## 2026-09-01 — RESEARCH: Flux substitution + HelmRelease best practice. **Measured semantics + ranked plan.**
+
+Three parallel research passes (substitution/ordering, HelmRelease/CNI, and a full repo audit),
+prompted by the incident above. Two of my own earlier conclusions were WRONG and are corrected
+here. Everything below marked *measured* was run against flux 2.4.0 / the live cluster; everything
+else is cited inference.
+
+### THE SUBSTITUTION SEMANTICS TABLE (measured — trust this over prose elsewhere)
+
+| form | behaviour |
+|---|---|
+| `${DEFINED}` | substituted |
+| `${UNDEFINED}` | **silently empty** (non-strict) · fails loudly (strict) |
+| `${UNDEFINED:-d}` | **default applied at reconcile time — `--strict` does NOT catch it** |
+| `${VAR:?msg}` | renders **the message as the value** — a non-empty WRONG value. ANTI-PATTERN. |
+| `${VAR:=192.168.1.50}` | silently ships the dev value to prod. ANTI-PATTERN. |
+| `$${VAR}` / `$${VAR:-d}` / `$${ARR[0]}` | literal — **escaping is TOTAL** |
+| `$VAR` / `$(cmd)` | untouched, no escaping needed |
+| `${...}` / `${a b}` / `${ARR[0]}` unescaped | **hard parse error — fails the whole Kustomization** |
+
+Flux exempts default-providing operators (`-`, `:-`, `+`, `:+`, `=`, `:=`, `?`, `:?`) from strict
+mode by design ("they intentionally handle the unset case"). **That is why strict mode would never
+have caught the gitea/nextcloud dead-guard bug**, and why a targeted check was required.
+
+**Doctrine corrected:** `clusters/base/apps-vms.yaml` claimed an indexed expansion is fatal
+"escaped or not". Measured: escaping is total; only the UNESCAPED form is fatal. Fixed in place.
+
+**Comment nuance:** `kustomize build` strips *structural* YAML comments before envsubst sees them,
+so those are usually harmless. But `#` lines INSIDE a block scalar are data and DO reach envsubst,
+and a `$`-carrying body comment was observed surviving into built `apps/wave-1`. Do not rely on
+stripping — escape in comments too. (An earlier claim in this log that a YAML comment "nearly broke
+every merge" was overstated for the structural case; the hazard is real for block-scalar bodies.)
+
+### CORRECTION 1 (mine) — `StrictPostBuildSubstitutions` alone is INSUFFICIENT
+
+It fixes nothing about ordering; it converts "render a corrupt value and ship it" into "fail loudly
+and keep last-good". **The actual ordering fix is one line**, verified against
+`kustomization_controller.go :: checkDependencies` at our exact version (v1.4.0): `dependsOn` is
+**revision-gated**, not merely Ready-gated — when the dependency shares a GitRepository, the
+dependent cannot reconcile revision N until the dependency has APPLIED revision N.
+
+`platform` is the only Kustomization in the graph with no `dependsOn`; every other consumer chains
+transitively through it. So:
+
+```yaml
+# clusters/base/platform.yaml
+spec:
+  dependsOn:
+    - name: flux-system     # cluster-vars must be applied at THIS revision first
+```
+
+**Cost, recorded honestly:** the root becomes a gate — a malformed manifest anywhere under
+`clusters/dev` now stops the whole graph where today it would not. Fail-closed, consistent with
+doctrine, but a real blast-radius change. No deadlock risk: the root runs `wait: false`.
+
+Rejected alternative: moving `cluster-vars` into the consuming Kustomization is **strictly worse** —
+`SubstituteVariables` reads the ConfigMap from the API at build time, *before* the Kustomization
+applies its own resources, so it would always read the PREVIOUS value. That converts an occasional
+race into a permanent one-reconcile lag.
+
+### CORRECTION 2 (an agent's) — the safety machinery DID fire
+
+A research pass concluded that Helm considered the bad release healthy (because
+`updateStrategy.rollingUpdate.maxUnavailable: 2` on 3 nodes means `expectedReady = 1`), and
+therefore remediation never engaged. **Measured on the live cluster: that is wrong.** The Helm
+release secrets show **v9 = `failed`**; Helm's wait DID fail and the release was remediated, which
+is why it self-healed. `maxUnavailable: 2 of desired 3` IS confirmed live — so the real harm was
+blast radius (2 of 3 agents down at once), not a missed detection.
+
+### Verified, and worth knowing
+
+- **Flux 2.4.0 is OUT OF SUPPORT** — the project supports the last three minors; 2.9.x is current.
+- **Strict substitution became DEFAULT-ON** in kustomize-controller v1.9.0. So upgrading Flux flips
+  this behaviour whether or not we opt in — the variable audit is a prerequisite for the upgrade
+  regardless of today's decision.
+- **Cilium's `values.schema.json` permits `k8sServiceHost: ""`** — no `minLength`, no `pattern`.
+  Helm was never going to reject the bad render.
+- **Cilium docs make `k8sServiceHost` REQUIRED under kube-proxy replacement**, precisely because the
+  environment exports the API ClusterIP and there is no kube-proxy to provision it.
+- **The Cilium chart ships zero test templates**, so `spec.test` is useless for it. A post-upgrade
+  check must live outside Helm.
+- `valuesFrom` fails HARD on a missing key (verified in `chartutil/values.go`) unlike postBuild's
+  silent empty — but only on a MISSING key, not an empty value, and it cannot cross namespaces
+  (`cluster-vars` is in `flux-system`; the Cilium HelmRelease is in `kube-system`).
+- **Do NOT enable `driftDetection.mode: enabled` on a CNI.** It compares the cluster against the
+  Helm storage manifest — during the incident that manifest WAS the bad render, so drift correction
+  would have actively re-asserted the broken value.
+
+### RANKED PLAN
+
+| P | Action | State |
+|---|---|---|
+| **P0** | `platform.dependsOn: [flux-system]` — closes the race completely | **PENDING — operator call** (blast-radius change) |
+| **P0** | Escape the dead OIDC guards; renderer now refuses the class | ✅ DONE |
+| **P1** | Substitution-safety L0 gate, unconditional in `ci/l0.sh` | ✅ DONE — 102 assertions |
+| **P1** | Enable `StrictPostBuildSubstitutions=true` | **READY — proven safe**, all 11 paths exit 0 under `flux envsubst --strict`. Sequence AFTER P0. |
+| **P2** | `updateStrategy.rollingUpdate.maxUnavailable: 1` on Cilium, as a new **[parity]** field in BOTH the HelmRelease and the Ansible j2 | PENDING — bounds blast radius to one node |
+| **P3** | Split Cilium into its own Kustomization (`wait: true`, `interval: 1h`, `timeout: 10m`); `platform` dependsOn it | PENDING — gives `flux suspend kustomization cilium` as an emergency valve |
+| **P4** | Upgrade Flux 2.4.0 → 2.9.x | PENDING — out of support; brings strict-by-default |
+| **P5** | Cilium MINOR bumps become manual (Renovate PR → human runs the documented pre-flight → merge). Never automerge a CNI minor. | PENDING — process |
+| — | Record `${VAR:?}` / `${VAR:=}` as anti-patterns | ✅ DONE (table above) |
+| — | *Not recommended*: drift detection on Cilium; `spec.test` on Cilium; `k8sServiceHost: auto` | — |
+
+### Follow-ups surfaced, not yet actioned
+- 6 dead `cluster-vars` knobs; `BASE_DOMAIN` and `CLUSTER_ENV` look like genuine rot.
+- `platform/{cilium,longhorn,velero,oauth2-proxy}/values.yaml` reference mirrors carry decorative
+  `${...}` that can silently drift from the real HelmRelease.
+- `platform` Kustomization `timeout: 5m` vs Longhorn HelmRelease `timeout: 15m` — the tier can time
+  out while a legitimate Longhorn upgrade is still running.

+          #   Its contract (drone/envsubst; the same one spelled out in clusters/base/apps-vms.yaml,
+          #   and re-verified against this exact file with `flux envsubst`, flux v2.4.0) is:
+          #     - A bare  $name  is NOT a reference to envsubst: it passes through untouched, and
+          #       that holds even when the name IS set in cluster-vars. So $i and $j reach the
+          #       cluster verbatim and both 60s bounds below are real, enforced bounds.
+          #     - $((i + 1))  is likewise untouched: "(" cannot begin a variable name.
+          #     - A BRACED dollar-name IS a reference and gets replaced — with the empty string
+          #       when the name is unset. One of those here would make a bound read [ "" -ge 60 ],
+          #       which errors, short-circuits the &&, and silently turns the wait UNBOUNDED.
+          #     - A DOUBLE-dollar braced name is envsubst's escape and survives as the braced
+          #       form — still wrong for us, because on any path where envsubst does NOT run
+          #       (a plain `kustomize build` or `kubectl apply -k` of this directory) the shell
+          #       reads that leading double-dollar as its own PID, so a bound would compare a
+          #       string like 1234{i} against 60. The bare form is the only spelling that is
+          #       correct on BOTH paths.
+          #     - A braced name containing punctuation is a HARD ERROR ("unable to parse variable
+          #       name") that fails this whole Kustomization — and this Kustomization gates every
+          #       merge in the repo. So never write one anywhere in this file, INCLUDING in a
+          #       comment. That is why this note names the three forms in words rather than
+          #       showing them: an earlier draft of it spelled them out literally and broke
+          #       `flux envsubst` on the file. (Same trap the indexed-expansion warning in

+        # FOLLOW-UP (deliberately NOT bundled into the readiness fix above — own change):
+        #   Convert this container into a NATIVE SIDECAR and delete both shell wait-loops.
+        #   k3s is now v1.36, where sidecar containers are GA, so kubelet can enforce the
+        #   ordering that the loops above hand-roll — which also removes the envsubst hazard
+        #   from this file entirely (no shell, no $i/$j, nothing to escape or mis-escape).
+        #   Shape to build:
+        #     1. Move this whole container into `initContainers:` as the FIRST entry.
+        #     2. Add `restartPolicy: Always` to it. That single field is what makes an
+        #        initContainer a sidecar: it starts before the regular containers, keeps
+        #        running alongside them, and is terminated after them.
+        #     3. Give it a `startupProbe` that succeeds only when dockerd accepts a TLS
+        #        connection — e.g. `exec` a `docker -H tcp://127.0.0.1:2376 --tlsverify
+        #        --tlscacert /certs/client/ca.pem --tlscert /certs/client/cert.pem
+        #        --tlskey /certs/client/key.pem info`. Do NOT use a bare `tcpSocket` probe:
+        #        it would re-open the same "port accepting but TLS/certs not ready" gap that
+        #        Stage 1 above exists to close. `periodSeconds: 1` + `failureThreshold: 60`
+        #        preserves today's 60s cap.
+        #     4. kubelet then holds the `runner` container until that startupProbe passes, so
+        #        `runner` can drop its `command:` override completely and run the image's
+        #        default entrypoint.
+        #   Why it is a separate change: this Deployment is the ENFORCED MERGE GATE for this
+        #   entire repository. If the conversion is wrong, nothing can merge — so it must land
+        #   alone, where the failure is unambiguous and not entangled with anything else, and
+        #   only after a real workflow run has been observed green on the converted pod.

There is **no single `apps` Kustomization** any more — the apps tier is now `apps-wave-0/1/2` + `apps-vms`, and SOPS decryption is layered on **per wave** (each wave Kustomization is patched by name in `clusters/dev`). |
 | `patches/flux-system-source-url.yaml` | Overrides the `flux-system` GitRepository `url` placeholder with the real bootstrap source (template — fill at bootstrap). |
 
+## Customizing the controllers (`components/`) — and how it reaches a RUNNING cluster
+
+Because this repo does not use `flux bootstrap`, the Flux controller Deployments are **not in git
+and not reconciled by Flux**. Verified on the live dev cluster (2026-09-01):
+
+```
+$ kubectl -n flux-system get deploy kustomize-controller -o jsonpath='{.metadata.labels}'
+{"app.kubernetes.io/component":"kustomize-controller","app.kubernetes.io/instance":"flux-system",
+ "app.kubernetes.io/part-of":"flux","app.kubernetes.io/version":"v2.4.0","control-plane":"controller"}
+# no kustomize.toolkit.fluxcd.io/name label; deployment.kubernetes.io/revision: 1
+```
+
+No `kustomize.toolkit.fluxcd.io/*` label => no Flux Kustomization owns it. **Nothing under
+`clusters/**` can change a controller flag.** So `bootstrap.sh` step 1 uses the mechanism Flux
+documents for hand-installed clusters ([Customize Flux
+manifests](https://fluxcd.io/flux/installation/#customize-flux-manifests)):
+
+```
+flux install --export …  ->  <tmp>/gotk-components.yaml     # regenerated from the pinned flux CLI
+components/kustomization.yaml -> <tmp>/kustomization.yaml   # the only hand-authored part (in git)
+kubectl kustomize <tmp> | kubectl apply -f -
+```
+
+Nothing is vendored into the repo, so the component manifests can never drift from `FLUX_VERSION`
+(`infra/devcontainer/versions.env`). Every future controller flag (vertical scaling, tolerations,
+more feature gates) is another entry in `components/kustomization.yaml`.
+
+### Rolling this out to the ALREADY-RUNNING dev cluster (operator/PM step — NOT automatic)
+
+> **A `git push` does not deliver this.** Merging the change reconciles `clusters/**` only; the
+> controller Deployment is outside Flux's inventory. Someone must run step 1.
+
+Re-running `bootstrap.sh` is safe and idempotent, but if you want only step 1:
+
+```bash
+# inside infra/devcontainer (pinned flux 2.4.0 / kubectl 1.36.4), from the repo root
+d=$(mktemp -d)
+flux install --export --namespace=flux-system \
+  --components-extra=image-reflector-controller,image-automation-controller > "$d/gotk-components.yaml"
+cp bootstrap/flux/components/kustomization.yaml "$d/kustomization.yaml"
+kubectl kustomize "$d" | kubectl apply -f -      # add --server-side --force-conflicts on a field-manager conflict
+kubectl -n flux-system rollout status deploy/kustomize-controller
+```
+
+**Expect kustomize-controller to restart** (new arg => new pod template => new ReplicaSet). Any
+reconcile in flight is interrupted and retried by the new pod; Flux is level-triggered, so nothing
+is lost. Confirm afterwards:
+
+```bash
+kubectl -n flux-system get deploy kustomize-controller \
+  -o jsonpath='{.spec.template.spec.containers[0].args}'   # must contain --feature-gates=StrictPostBuildSubstitutions=true
+flux get kustomizations -A                                  # all 11 must return to Ready
+```
+
+**Rollback** is the same command with `FLUX_INSTALL_PLAIN=1 bash bootstrap/flux/bootstrap.sh`, or
+simply `flux install --namespace=flux-system --components-extra=…` (drops the arg back off).
+
 ## Why `flux install` + apply, not `flux bootstrap git` (Phase 1)
 
 The reconciliation graph is **already authored** in `clusters/base` (read-only to this worker):
-`flux-system.yaml` is the `flux-system` **GitRepository**; `platform.yaml`/`apps.yaml` are the Flux
-**Kustomizations**; `clusters/dev` is the overlay that patches `cluster-vars` (R-ENV-02).
+`flux-system.yaml` is the `flux-system` **GitRepository**; `platform.yaml`, `platform-config.yaml`
+and the app-wave Kustomizations (`apps-wave-0/1/2.yaml` + `apps-vms.yaml` — the single `apps.yaml`

+The `l0` stage has three sub-stages: ServiceDefinition schema validation, the Kyverno policy gate
+(`kyverno test`), and **`conformance/run.sh --layer l0`** — the whole-repo L0 invariants a
+per-resource policy cannot express (secret hygiene across every tracked file, least-privilege RBAC,
+spec-immutability enforcement). See `conformance/tests/README.md`.
+
 ## Exit-code contract
 
 Every stage script uses: **`0` = pass · `1` = fail (blocks merge) · `3` = SKIPPED** (cluster-gated
 with no cluster, or an unwired seam / missing tool). A `3` is **never** counted as green — that is how
 the gate stays honest in Phase 0 (no fake green).
 
+### The touched-requirement subset can also be *undeterminable* (exit 3)
+
+`touched-requirements.sh` is the input to the R-TEST-03 decision. It resolves a diff base in this
+order, **verifying each candidate exists** before using it:
+
+```
+BASE_REF (explicit)  >  GITHUB_BASE_REF (Actions PR runs)  >  origin/main  >  main
+```
+
+If no candidate resolves, if there is no merge base, if the diff command fails, or if **HEAD is not
+ahead of the base** (you are sitting on `main`, or the branch is already merged), it prints a loud
+banner, writes **nothing** to stdout, and exits **3** — plus a machine-readable reason code
+(`on-base` / `no-base` / `diff-failed`) to `$TOUCHED_REASON_FILE` when that variable names a path.
+
+**Why this is not cosmetic.** Every one of those conditions used to degrade *silently* to an empty
+touched set and exit 0. An empty set means `conformance/run.sh` is invoked with no `--requirements`,
+which means its coverage `--require` gate never runs — so on 2026-08-31 the local gate printed
+`MERGE GATE: PASS` having checked nothing, while CI (correct base, 17 touched requirements) BLOCKED
+on real coverage debt. There is no silent narrowing left: the `HEAD~1` last resort and the two-dot
+diff fallback are both gone. Locked down by `ci/tests/touched-requirements-base.test.sh`.
+
+`gate.sh` turns exit 3 into an **UNDECIDED** merge decision, never a pass:
+
+| reason | headline | exit |
+|---|---|---|
+| `on-base` | `MERGE GATE: NOT APPLICABLE — no branch under gate` | 0 (a push-to-`main` CI run legitimately lands here; it just must not read as "my branch is green") |
+| `no-base`, `diff-failed` | `MERGE GATE: BLOCKED` | 1 (the environment cannot support a merge decision; refusing to decide must not look like deciding yes) |
+
+A stage that needs the subset (`l0.sh`, `l1.sh`) still runs its FULL layer as a superset sanity net
+in that case — nothing goes untested — and says plainly that the *scoped* check did not happen.

+# THE BUG THESE LOCK DOWN (2026-08-31, local/CI divergence):
+#   `make -C ci gate` on a feature branch printed
+#       "no changed files vs base; empty touched-requirement set"
+#   and then "MERGE GATE: PASS" — while CI, with a correct base, computed 17 touched
+#   requirements and BLOCKED on real coverage debt. Root cause: EVERY way of failing to
+#   establish a diff base degraded silently to an EMPTY touched set and exit 0. An empty
+#   set means conformance/run.sh is invoked without `--requirements`, which means its
+#   coverage `--require` gate never runs — so the gate reported PASS having checked
+#   nothing. A false green is worse than a red.
+#
+#   The fix: an undeterminable base is a LOUD exit 3 (ci/README.md's SKIPPED code) with
+#   EMPTY stdout and a machine-readable reason code, never exit 0. These tests assert
+#   that for each way the base can be undeterminable, and assert the good paths still work.

+# BUG THIS FIXES (local/CI divergence, 2026-08-31): every failure to establish a
+# reliable diff base used to degrade SILENTLY to an EMPTY touched set, which main()
+# reported as "no changed files vs base" and exit 0. An empty set means the coverage
+# `--require` gate is never applied, so the merge gate printed "MERGE GATE: PASS"
+# having checked NOTHING — while CI, with a correct base, computed 17 touched
+# requirements and blocked. A false green is the worst outcome this project can
+# produce, so every one of those degradations is now a LOUD exit 3:
+#
+#   * HEAD~1 last resort  REMOVED. It silently narrowed the diff to the last commit
+#                         (and on a one-commit repo failed into an empty set).
+#   * two-dot fallback    REMOVED. It masked a failing three-dot diff as "no changes".
+#   * unresolvable base   exit 3 (was: HEAD~1 or empty).
+#   * diff command fails  exit 3 (was: empty set).
+#   * HEAD not ahead of   exit 3 (was: exit 0 with an empty set — this is the case
+#     the base                that produced the false green: running the gate while
+#                             sitting on `main`, or on a branch already merged).

+### LAN addressing is a knob, not a literal (fixed 2026-08-31)
+
+Until 2026-08-31 the base manifests hardcoded the **dev** LAN: the k3s API host Cilium dials, the
+Cilium LB IP pool range, the pinned crafty/unifi L4 VIPs and the off-cluster S3 backup endpoint. That
+broke R-ENV-02 outright — `clusters/prod` would have rendered dev addresses (192.168.1.x) onto the
+prod LAN (192.168.2.x). They are now the `cluster-vars` "LAN addressing" block
+(`K3S_API_HOST`, `CILIUM_LB_POOL_START`/`_STOP`, `UNIFI_L4_VIP`, `CRAFTY_L4_VIP`,
+`S3_BACKUP_ENDPOINT`, alongside the pre-existing `GATEWAY_VIP`), set explicitly by BOTH overlays.
+
+Two rules when touching that block:
+
+1. **Substitution coverage.** A `${TOKEN}` only resolves in a path whose Flux Kustomization declares
+   `postBuild.substituteFrom: cluster-vars`; anywhere else the literal string `${TOKEN}` ships to the
+   cluster. `apps-vms` was the one path without it and now has it — which means every shell `${...}`
+   in a VM manifest's cloud-init must be escaped `$${...}` (see `clusters/base/apps-vms.yaml` for the
+   full envsubst escape contract).
+2. **`GATEWAY_VIP` must be inside `CILIUM_LB_POOL_START..STOP`,** and in practice equal to START: the
+   `shared` Gateway pins no address, so Cilium LB-IPAM gives it the pool's first free IP while
+   split-horizon CoreDNS answers with `${GATEWAY_VIP}`. A VIP outside the pool blackholes in-cluster
+   hairpin traffic while the Gateway still looks healthy.
+
+Values the operator has not decided are `TBD-PROD-*` placeholders, not guesses: prod inherits the
+DEV base defaults if an overlay op is simply omitted, so an invalid value that fails loudly is
+strictly safer than a plausible one that quietly comes up on the wrong network.

+
+`coverage.md` answers **"does a requirement-tagged test EXIST for R-x?"** (R-TEST-04).
+`status.md` (`./run.sh --status`, generator `lib/status.py`) answers the operator's

+1. **implementation** — is there a tracked artifact naming the requirement?
+2. **reconciliation** — is that artifact reachable by walking `resources:` from
+   `clusters/<env>/kustomization.yaml` and expanding every Flux `Kustomization`'s
+   `spec.path`? This is what separates **authored** from **actually reconciled**: a

+"""Requirement STATUS report — derived from repository state, not from a task board.
+
+WHY THIS EXISTS
+---------------
+`lib/coverage.py` answers exactly one question: *does a requirement-tagged test exist
+for R-x?* (R-TEST-04). That is necessary but not sufficient: a requirement can have a
+tagged test that is a pure TODO scaffold, and can have implementing manifests that are
+authored in git but never reconciled by Flux. Both read as "covered"/"delivered" while
+nothing is actually true of the cluster.
+
+This generator derives, from the REPOSITORY ALONE, three orthogonal axes per requirement:
+
+  1. IMPLEMENTATION  — is there implementing config in the repo, and is it reachable
+                       from a Flux Kustomization entrypoint (i.e. actually reconciled)?
+  2. VERIFICATION    — is there a requirement-tagged test, at which layer, and is it an
+                       EXECUTABLE test or a TODO scaffold?
+  3. PROOF           — has that test actually passed?  *** DELIBERATELY NOT DERIVED. ***
+
+WHAT THIS TOOL REFUSES TO DERIVE (and why)
+------------------------------------------
+PROOF-OF-PASS IS NOT DERIVABLE FROM REPO STATE. Nothing tracked in git records a test
+result: `conformance/_artifacts/` and `results/` are git-ignored, and the only prose
+record of a green run lives in DECISIONS-LOG.md — hand-maintained, unstructured, and
+exactly the kind of source the operator has ruled out. The project's own culture is that
+"merged" is never "done" (agents/definition-of-done.md, R-TEST-03), so this report will
+NOT infer, guess, or default a requirement to green. Every requirement's proof state is
+reported as `not-derivable`, and the headline says so. If an untracked JUnit artifact
+happens to be lying in the workspace it is surfaced ONLY as a quarantined advisory with
+its mtime — never counted, never mixed into a status.
+
+The honest fix is a committed, machine-readable run ledger; until that exists, the most
+this report can say is "wired and testable", never "proven".
+

+
+docs/14's L0 row is *"Pre-apply, in CI · manifests/ServiceDefinitions obey invariants"*.
+Kyverno (`platform/kyverno/`) covers the invariants expressible over a **single
+resource**. This subtree covers the L0 invariants that are **properties of the repository
+as a whole** and that no per-resource policy can state — e.g. *no plaintext secret exists
+anywhere in the tracked tree*, *no tracked RoleBinding grants a workload identity a
+privileged role*, *the spec-immutability gate actually blocks a modified spec*.
+
+Each `l0-static/<name>/` dir carries a **`check.sh`**: a self-contained offline assertion
+script (git + Python stdlib/PyYAML; no cluster, no network) that exits 0/1. It is executed:
+
+- by `conformance/run.sh --layer l0` (and as the offline leg of a full run), via
+  `lib/run_l1_offline.py`, producing a REAL pass/fail JUnit entry — never a skip; and
+- by the merge gate's **`ci/l0.sh`** stage, so these assertions run on every PR; and
+- by the wrapping Chainsaw `Test`, which runs the SAME `check.sh`, so an in-cluster run
+  executes byte-identical assertions.
+
+Two authoring rules specific to this layer:
+
+1. **State the gap.** A statically-provable half of a requirement is still only half.
+   Every `check.sh` header ends with an explicit *"what this does NOT prove"* list naming
+   the cluster-layer remainder. Covering a requirement at L0 does not finish it.
+2. **Exemptions must be self-policing.** Where a check must tolerate something (a
+   deliberately-plaintext policy fixture, an `.example` template), the exemption is
+   conditioned on a property that would break if the exemption were abused — e.g. the
+   plaintext Secret fixture is exempt *only while* a `kyverno-test.yaml` asserts the
+   policy rejects it. Never a bare path allowlist.

+# L0 static check (offline, no cluster) — flux-postbuild-substitution
+# Serves: R-ENV-02 ("Same GitOps config promotes dev/test -> prod (authored once)."
+#                   — spec docs/02-environments-and-provisioning.md)
+#         R-GITOPS-01 ("All desired state in git, reconciled by Flux."
+#                   — spec docs/05-gitops-and-delivery.md)
+#
+# WHY THIS EXISTS — Flux post-build substitution FAILS OPEN
+# --------------------------------------------------------
+# R-ENV-02 is implemented by exactly one mechanism: `clusters/base/cluster-vars.yaml`
+# is injected into every `${TOKEN}` of the manifests each Flux Kustomization renders,
+# via `postBuild.substituteFrom`. That mechanism is silently lossy by default: an
+# UNDEFINED variable becomes the EMPTY STRING and the Kustomization still reports
+# Ready. On 2026-09-01 that emptied `k8sServiceHost` in the Cilium HelmRelease and put
+# cilium into Init:Error on 2 of 3 dev nodes (DECISIONS-LOG "substitution race that
+# fails OPEN"). "Authored once, promoted" is therefore only true while every token a
+# substituted path renders is either DEFINED or deliberately ESCAPED — and nothing in
+# the repo asserted that. This check does.
+#
+# ENVSUBST BEHAVIOUR ASSERTED HERE (empirically verified against the pinned toolchain,
+# `flux envsubst`, flux 2.4.0 — this is measured behaviour, not assumption):
+#   ${DEFINED}        -> substituted with the cluster-vars value.
+#   ${UNDEFINED}      -> EMPTY STRING, silently. `--strict` / the cluster-wide
+#                        StrictPostBuildSubstitutions feature gate turns this into a
+#                        loud Kustomization failure ("variable not set (strict mode)").
+#   ${UNDEFINED:-d}   -> the DEFAULT is applied AT RECONCILE TIME. Strict mode does
+#                        NOT catch this (it exempts default-operator forms by design),
+#                        so a shell guard written `[ -z "${X:-}" ]` inside a rendered
+#                        manifest is pre-resolved to `[ -z "" ]` and its else-branch
+#                        becomes unreachable in the container. Silent, and permanent.
+#   $${VAR}, $${V:-d}, $${ARR[0]}  -> emitted as the LITERAL ${...} for a downstream
+#                        shell/cloud-init consumer. Escaping is total: it neutralises
+#                        even the indexed form.
+#   $VAR, $(cmd)      -> left alone by envsubst; they need no escaping.
+#   ${...}, ${a b}, ${ARR[0]}  (UNESCAPED) -> HARD PARSE ERROR ("unable to parse
+#                        variable name" / "missing closing brace") which fails the
+#                        WHOLE Kustomization — every resource in the path, not just
+#                        the offending one.
+# The escape contract this enforces is the one already documented in
+# `clusters/base/apps-vms.yaml`; this check is that comment made executable.
+#
+# GIVEN the repository as authored,
+# WHEN  every Flux Kustomization under clusters/ that declares postBuild.substituteFrom
+#       is resolved to the exact file set its `spec.path` renders (by following
+#       kustomization.yaml `resources:` transitively — a path, not a glob),
+# THEN  (1) every `${...}` in those files is DEFINED in cluster-vars, or ESCAPED `$${...}`;
+#       (2) no UNESCAPED expansion carries a default/length/substitution operator on an
+#           undefined name (the silent-empty class strict mode does not catch);
+#       (3) no UNESCAPED expansion is unparseable by envsubst (`${...}`, `${ARR[0]}`) —
+#           that fails the entire Kustomization, so it is fatal wherever it appears;
+#       (4) every Kustomization that renders a cluster-vars token actually declares
+#           `substituteFrom` a ConfigMap named cluster-vars (else the literal token
+#           ships into the cluster);
+#       (5) every knob an overlay patches (`/data/KEY`) exists in the BASE ConfigMap —
+#           the "add the knob with a base default BEFORE referencing it" rule that the
+#           incident's interim discipline depends on;
+#   AND (6) this check is LOAD-BEARING: ci/l0.sh runs it on every gate run and
+#           ci/gate.sh sets the merge block when the l0 stage fails.
+# Assertion (1)-(3) are applied to COMMENTS as well as content: `kustomize build`
+# preserves body comments into the stream envsubst reads (verified: a `$`-carrying
+# comment survives into the built apps/wave-1 output), so a braced expression in a
+# comment is a live hazard, not prose.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — this is a STATIC check):
+#   - It does NOT render the manifests. It scans the SOURCE files a path includes,
+#     which is a deliberate SUPERSET of the post-`kustomize build` stream (kustomize
+#     drops some comments). A finding in a comment may not reach envsubst TODAY; it is
+#     still reported, because whether a given comment survives the build is a kustomize
+#     implementation detail that changes with the pinned version, and the failure it
+#     causes is total (assertion 3). The end-to-end proof — `kustomize build <path> |
+#     flux envsubst --strict` for every substituted path — needs kustomize + flux,
+#     which the L0 CI toolchain does not install (.gitea/workflows/scripts/install-tools.sh
+#     l0), so it cannot run here without permanently SKIPPING. It was run by hand and
+#     recorded in DECISIONS-LOG; this check is the reproducible static half.
+#   - It does NOT prove the cluster's live state matches git, nor that the
+#     StrictPostBuildSubstitutions feature gate is actually enabled on
+#     kustomize-controller. Both are cluster facts (L2), untested here. Tagging
+#     R-GITOPS-01 claims ONLY the static slice: what git says a Kustomization renders
+#     is fully determined, with no variable silently emptied on the way in.
+#   - It does NOT validate cluster-vars VALUES (that GATEWAY_VIP is inside the LB pool,
+#     that an overlay's LAN block is self-consistent). Presence, not correctness.
+#   - A cluster-vars key nothing references is reported as an ADVISORY, never a failure:
+#     several are deliberately reference-only and say so in cluster-vars.yaml
+#     (PIA_REGION "retained, not substituted"; CLUSTER_POD_CIDR "Documents ..."), so
+#     failing on them would be a false block on documented intent.

+# The requirement has TWO halves and this check covers the STATIC half of each,
+# at the layer docs/14 puts them ("L0 Static/policy | Pre-apply, in CI").
+#
+# GIVEN the repository as git tracks it,
+# WHEN  every tracked RBAC object and every least-network-reach policy is inspected,
+# THEN — workload identity —
+#       (1) no in-repo Role/ClusterRole grants a wildcard apiGroup, resource or verb,
+#           and none grants escalate/bind/impersonate (the privilege-escalation verbs);
+#       (2) no (Cluster)RoleBinding binds a ServiceAccount — a WORKLOAD identity — to
+#           `cluster-admin` or to any in-repo role holding wildcard rules. Human/Group
+#           subjects are out of scope: R-SEC-02 constrains workload identities, and the
+#           operator's own admin path is an OIDC group binding, deliberately;
+#       (3) every ServiceAccount subject is namespaced (no cluster-wide ambiguity);
+#       (4) the conformance runner's own SA — this workstream's PRIVILEGED TEST
+#           IDENTITY, whose least-privilege authoring docs/14 explicitly delegates to
+#           WS-TEST — is bound only to its own scoped ClusterRole, carries no wildcard
+#           and no privilege-escalation verb, and grants nothing over RBAC objects
+#           themselves (no rbac.authorization.k8s.io rules);
+#     — network reach —
+#       (5) the policies that implement least network reach exist, and each is Enforce
+#           (or carries the Flux token that substitutes to Enforce): the default-deny
+#           baseline generator, the baseline SHAPE validator, the host-namespace/
+#           privilege restriction, and the egress-class label requirement;
+#       (6) each of those policies is actually EXERCISED by the L0 Kyverno suite with a
+#           NEGATIVE row (result: fail) — a policy nobody proves rejects anything is a
+#           declaration, not a gate.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gap, cluster layer — R-SEC-02 is NOT fully covered):
+#   - RUNTIME least privilege of workload identities: that the API server actually
+#     denies the conformance SA (or any workload SA) the verbs it was not granted.
+#     That needs a live cluster (L2) and no test asserts it today.
+#   - RUNTIME least network reach: that pod-to-pod traffic is actually denied. The
+#     behaviour is exercised by tests/l2-behavioral/{default-deny,deny-undeclared},
+#     but those are tagged R-NET-01/R-NET-02 and are cluster-gated (skipped in Phase 0);
+#     nothing proves it under an R-SEC-02 tag.
+#   - Helm-chart-generated RBAC (e.g. what a HelmRelease's chart creates in-cluster) is
+#     not in the repo, so it is outside this static scan entirely.

+# Serves: R-SEC-01 ("Secrets MUST NOT be stored in plaintext in git; they MUST be
+#         encrypted at rest in the repo and decrypted only in-cluster."
+#         — spec docs/00-vision-and-scope.md; detail in docs/07.)
+#
+# docs/14 puts exactly this invariant at L0 ("Static/policy | Pre-apply, in CI |
+# ... no plaintext secrets"), so it is asserted here over the WHOLE tracked tree,
+# with no cluster. Run by `conformance/run.sh --layer l0` and by ci/l0.sh.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  every tracked file is inspected,
+# THEN  (1) SOPS is configured at the repo root with a PUBLIC age recipient;
+#       (2) every committed Kubernetes Secret is SOPS-encrypted — a top-level
+#           `sops:` block with a mac AND every data/stringData value is ENC[...];
+#       (3) the only two exempt classes are narrow and self-policing:
+#             a. `*.example` templates, which must NOT be referenced by any
+#                kustomization and whose secret-named values must be placeholders;
+#             b. the Kyverno L0 negative fixture, which is exempt ONLY while it is
+#                actually wired into a kyverno-test.yaml that asserts
+#                `disallow-plaintext-secrets` REJECTS it (result: fail);
+#       (4) every ansible-vault group_vars file is `$ANSIBLE_VAULT;`-encrypted, and
+#           no secret-valued ansible key carries a literal outside a vault;
+#       (5) no private key material of any kind is tracked (PEM private keys, an
+#           age SECRET key, kubeconfig client-key-data);
+#       (6) decryption is delegated to the cluster: a Flux Kustomization declares
+#           `decryption.provider: sops` with a secretRef, and the private half of
+#           that key pair is nowhere in the repo (5).
+#
+# WHAT THIS DOES *NOT* PROVE (honest gap, cluster layer):
+#   - that the decrypted Secret only ever materialises in-cluster (the runtime half
+#     of "decrypted only in-cluster") — needs a live cluster (L2), untested today.
+#   - that no plaintext secret exists in git HISTORY. This walks the WORKING TREE at
+#     HEAD only; docs/07's history-scan acceptance gate needs a secret scanner over
+#     all revisions and is NOT implemented here.
+#   - value-level entropy: a placeholder-looking string that is in fact a real
+#     credential is not detectable statically.

+# HOW A GOVERNANCE RULE IS MADE TESTABLE
+# -------------------------------------
+# "An agent must not do X" cannot be proven by observing that no agent did X today.
+# What CAN be proven — and is what actually protects the spec — is that the MECHANISM
+# which detects and blocks a spec modification works, and is wired into the merge gate
+# as a blocking stage. So this test drives the real `ci/spec-immutability.sh` against
+# HERMETIC THROWAWAY spec repositories and asserts its exit-code behaviour.
+#
+# THE REAL SPEC REPO IS NEVER TOUCHED. Every case runs against a fixture git repo under
+# mktemp, with SPEC_REPO pointed at it and a COPY of ci/ (so the fixture's SPEC_PIN can
+# be set without editing the tracked one). Nothing here writes outside its temp dir —
+# which is itself the R-TEST-06 discipline this test exists to defend.
+#
+# GIVEN the enforcement mechanism (ci/spec-immutability.sh + ci/SPEC_PIN),
+# WHEN  it is run against a spec repo in each state,
+# THEN  (1) clean and at the pinned SHA           -> exit 0 (pass)
+#       (2) an UNCOMMITTED edit under docs/       -> exit 1 (blocks the merge)
+#       (3) an uncommitted edit under decisions/  -> exit 1 (accepted ADRs are spec too)
+#       (4) a NEW COMMIT (HEAD drifted from pin)  -> exit 1 (an "adopted" change must be
+#                                                    an explicit reviewed SPEC_PIN bump)
+#       (5) an untracked file added to the spec   -> exit 1 (porcelain catches additions)
+#       (6) the spec repo absent                  -> exit 3 (honest SKIP, never green)
+#       (7) an empty/comment-only SPEC_PIN        -> exit 1 (an unpinned gate is no gate)
+# AND   (8) the tracked ci/SPEC_PIN really is a 40-hex commit SHA, and
+#       (9) the gate wires spec-immutability as a stage whose FAIL sets the merge block —
+#           i.e. the mechanism above is load-bearing, not dead code.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gap):
+#   - That the Gitea server actually REQUIRES this status check before merge. Branch

 # DISK MODEL — CDI DataVolume on Longhorn (NOT an ephemeral containerDisk):
-#   KubeVirt v1.9 supplies the container-disk binary to the `volumerootdisk` init
-#   container via a Kubernetes-native `image` volume (VolumeSource.Image) mounted at
-#   /container-disk-binary. That k8s feature is gated by the ALPHA `ImageVolume`
-#   feature gate, which is DISABLED on this k3s v1.31 cluster — so the apiserver

-#   containerDisk VM dies at OCI init with:
-#     exec: "/container-disk-binary/usr/bin/container-disk": no such file or directory
-#   A DataVolume-backed root is a mounted Longhorn PVC (CDI imports the same Fedora
-#   image into it out-of-band via its importer pod) and therefore does NOT touch the
-#   container-disk binary / image-volume path at all — it boots on this cluster. It is
-#   also the disk model the SPEC requires for VMs (docs/06, R-STATE-01: Longhorn-backed
-#   disks that survive rebuild), so this mirrors the representative fixtures/vm.yaml.
-#   Cost: a one-time CDI import per run (covered by the raised exec timeout below).
+#   The SPEC requires VMs to use Longhorn-backed disks that survive rebuild (docs/06,
+#   R-STATE-01), so this test — like fixtures/vm.yaml and the L3 vm-data-survival partner
+#   — boots from a CDI DataVolume on a Longhorn PVC (CDI imports the Fedora image into it
+#   out-of-band via its importer pod, so the VM never touches the container-disk binary /
+#   image-volume path). Cost: a one-time CDI import per run (covered by the raised exec
+#   timeout below).
+#   FEATURE-GATE NOTE (revalidated 2026-08 — the original "containerDisk is broken here"
+#   rationale is now STALE): KubeVirt v1.9 supplies the container-disk binary to the
+#   `volumerootdisk` init container via a Kubernetes-native `image` volume
+#   (VolumeSource.Image) mounted at /container-disk-binary, gated by the `ImageVolume`
+#   feature gate. On the ORIGINAL k3s v1.31 cluster that ALPHA gate was DISABLED, so the
+#   apiserver silently PRUNED the image volume + its mount and a containerDisk VM died at
+#   OCI init ("/container-disk-binary/usr/bin/container-disk: no such file or directory").
+#   The cluster is now k3s v1.36.4, where ImageVolume is ENABLED by default

+#       PROVABLY OUTSIDE this cluster,
+# WHEN  a backup of that namespace + its volume data is written to that off-cluster

+# THEN  a Velero restore into a CLEAN, previously-nonexistent namespace brings the
+#       workload back and the known data reads back byte-identical.
 #
-# R-TEST-05: proves recoverability by restoring into a genuinely clean namespace
-# (not by reading the still-live original). Backup TARGET is OQ-BKP (OPEN) — the
-# restore mechanism is Velero (T-4.3/T-4.4); this scaffold is target-agnostic.
+# R-TEST-05 (fault injection, not happy-path): the restore is only meaningful because
+# the source is annihilated first. After the destroy step there is no PVC, no PV and
+# no Longhorn volume left in the cluster holding this data — so the bytes that come
+# back can ONLY have come from the off-cluster object store. A restore that silently
+# rebound a surviving in-cluster PV is explicitly excluded: the test captures the
+# original PV name, asserts it is GONE, and asserts the restored PVC is bound to a
+# DIFFERENT, newly provisioned PV.
 #
-# STATUS: scaffold — needs T-4.3 (Velero + off-cluster schedule) + T-4.4 (drill).
-# BLOCKED-BY spec open question OQ-BKP (off-cluster backup target) — see report.
+# HOW "OFF-CLUSTER" IS PROVEN (not assumed) — step `assert-backup-target-is-off-cluster`:
+#   1. The BackupStorageLocation reports phase `Available` — Velero itself has
+#      successfully reached and validated that object store.
+#   2. Its endpoint host is resolved to an IPv4 address and asserted to be NONE of:
+#      loopback; any Node InternalIP/ExternalIP; any Service ClusterIP; any Pod IP;
+#      inside any node's `spec.podCIDR(s)`; inside any `ServiceCIDR` (best-effort).
+#      It is also asserted not to be a cluster-internal DNS name (*.svc,
+#      *.cluster.local, localhost). => the bytes leave the cluster's address space.
+#   3. The backup's PodVolumeBackup carries a non-empty `status.snapshotID` — the
+#      kopia snapshot really landed in the remote repository, i.e. VOLUME DATA (not
+#      merely Kubernetes resource JSON) was uploaded off-cluster.
+#   4. Plus the destroy-then-restore sequence above, which removes every in-cluster
+#      alternative source for the data.
+#
+# KNOWN, DELIBERATE GAPS (asserted nowhere — do not read this test as claiming them):
+#   * OFF-HOST is NOT proven, only OFF-CLUSTER. On the dev estate the k3s nodes are
+#     VMs on the same Proxmox host that runs the versitygw S3 target (192.168.1.9),
+#     so this drill does not survive loss of that hypervisor. Off-site/off-host
+#     replication is an operator concern outside R-STATE-03's wording.
+#   * The test does NOT read the backup objects out of the bucket with an S3 client.
+#     Doing so would require handing the conformance runner the backup credential,
+#     widening a privileged test identity for weaker evidence than (1)-(4) above.
+#   * The test restores its OWN scratch workload, never a real service's data. A
+#     per-service drill (Nextcloud/Gitea/CNPG) stays an operator exercise.
+#   * Bare-metal DR (rebuild the cluster itself, then restore) is NOT exercised; this
+#     asserts namespace+volume restore into a live cluster, which is what the catalog
+#     entry and the DoD line ask for.
+#   * Backup ENCRYPTION at rest and retention/GC behaviour are not asserted.
+#
+# RUNNABLE / SELF-SKIPPING (a skip is honest; a fake pass is a defect). Skips CLEANLY
+# (green) when a precondition is absent: no `longhorn` StorageClass; no Velero API
+# (CRDs absent); no BackupStorageLocation configured at all; Velero server or its
+# node-agent DaemonSet not ready. It runs the full drill the moment those exist — no
+# edit needed. RBAC denial is NOT a skip: it fails loudly as a harness defect.
+#
+# DESTRUCTIVE BY DESIGN, SCOPED BY CONSTRUCTION: every object it destroys is one it
+# created itself, in two namespaces it names after its own Chainsaw namespace
+# (`<ns>-dr-src`, `<ns>-dr-dst`) and labels `conformance.home.k3s/created-by=<ns>`.
+# It never touches a real service's namespace, PVC or PV, and it never deletes a
+# Backup it did not create.
+#
+# TEARDOWN ALWAYS RUNS (`finally`, even on failure/timeout/panic): both scratch
+# namespaces, any leftover PV, the Restore CR, and the Backup — the latter via a
+# Velero DeleteBackupRequest so the objects are removed from the bucket too, with a
+# short `ttl` on the Backup as a belt-and-braces backstop if that request is lost.

+# Evaluation: Cilium 1.20.1 native Gateway API ExternalAuth vs. the oauth2-proxy design
+
+**Status:** Research + plan only — NO live change proposed for tonight. Reviewable evaluation.
+**Author:** WS-NET/WS-SEC investigation (Claude Opus 4.8), 2026-08-31.
+**Scope:** Whether Cilium 1.20.1's native Gateway API `ExternalAuth` filter (GEP-1494) can replace
+(a) the hand-authored, **un-wired** forward-auth `CiliumClusterwideEnvoyConfig`
+(`platform/oauth2-proxy/forward-auth-cec.yaml`) and (b) Crafty's per-pod oauth2-proxy **sidecar**.
+**Answers the open item** from DECISIONS-LOG (2026-08-30): *"the Cilium ext_authz/forward-auth
+workaround relevance under 1.20.1."*
+
+---
+
+## TL;DR — Verdict: **DEFER (partial-feasible, not viable as-is tonight)**
+
+Native `ExternalAuth` **exists in the Cilium 1.20.1 codebase** and *could* eventually replace both
+mechanisms with a single, Gateway-API-native, per-route filter. **But it is NOT usable on this
+cluster in its current state**, and adopting it is a non-trivial, elevated-risk change to the exact
+shared Gateway that SSO was just stabilized on. Recommendation: **keep the current design, do not
+adopt now.** Track native ExternalAuth as the long-term target and revisit after the blocking
+conditions below clear.
+
+Three hard blockers, in order of severity:
+
+1. **The cluster's Gateway API CRDs are the `standard` channel — the `ExternalAuth` HTTPRoute filter
+   is not even installable.** Verified live: the `httproutes.gateway.networking.k8s.io` CRD is
+   `gateway.networking.k8s.io/channel: standard`, bundle `v1.6.1`, and its `filters[].type` enum is
+   exactly `[RequestHeaderModifier, ResponseHeaderModifier, RequestMirror, RequestRedirect,
+   URLRewrite, ExtensionRef, CORS]` — **`ExternalAuth` is absent**. GEP-1494 is an **experimental**
+   Gateway API feature; using it requires swapping the cluster-wide Gateway API CRDs to the
+   **experimental channel** bundle. That is a breaking, cluster-wide CRD change, and it must be kept
+   in lock-step with the Ansible-bootstrap ↔ Flux **parity contract**.
+2. **The feature is young and shipped with a fail-**open** security bug.** `ExternalAuth` landed in
+   Cilium **1.20.0** (2026-07-29, PR #45739). Issue **#47178 "Basic externalauth setup fails open"**
+   was filed against 1.20.0-rc.0 — the ext_authz filter silently produced no Envoy entry and let
+   **unauthenticated traffic through**. The fix (PR #47265) was backported to the 1.20 branch
+   (~2026-07-21) and should be in 1.20.0/1.20.1, but a fail-**open** regression in a brand-new
+   security-critical filter is exactly the failure mode R-IDP-02 forbids. Confidence that today's
+   filter is robust is low, and documentation is thin (Cilium ships **no** `external-auth` docs page
+   in 1.20 — the dedicated doc URL 404s; the stable Gateway API doc page makes no mention of it).
+3. **`enforce_policy_on_l7lb` (the CVE-2025-30162 hairpin behavior) will bite the ext_authz hop too.**
+   Commit `68690e5` just fixed cluster-wide SSO breakage: after the 1.16.5→1.20.1 jump, the shared
+   Gateway's L7 proxy re-evaluates a pod's **egress policy against the *real backend* identity** when
+   it hairpins (`enforce_policy_on_l7lb`), so every NetworkPolicy'd app needed an explicit
+   `toEndpoints` egress allow to the Keycloak backend. A Gateway-level `ExternalAuth` filter makes the
+   Gateway's Envoy hairpin to the **oauth2-proxy** backend cluster for the auth check — the identical
+   class of policy re-evaluation. Expect to need new egress/identity allowances for the ext_authz
+   path, and to re-validate it does not regress the freshly-fixed Keycloak egress.
+
+Given SSO "was just painfully fixed," the cost/benefit does not favor touching it now.
+
+---
+
+## Current state (verified — live cluster + repo)
+
+**Cluster:** Cilium `v1.20.1` (`quay.io/cilium/cilium:v1.20.1`), Gateway API CRDs bundle `v1.6.1`
+**standard** channel, k3s v1.36.4. Shared Gateway `gateway/shared` (class `cilium`, VIP
+`192.168.1.53`, Programmed), backed by the machine-owned `CiliumEnvoyConfig
+gateway/cilium-gateway-shared` (the only CEC/CCEC on the cluster). `cilium-config` has
+`enable-gateway-api: true` and **no** external-auth flag (`mesh-auth-*` is the unrelated SPIFFE
+mutual-auth feature and is disabled).
+
+**Auth design today (three mechanisms, one of them dead):**
+
+| Mechanism | Where | Apps | Status |
+|---|---|---|---|
+| **Native OIDC** (`auth.mode: oidc`) | in-app OIDC client → Keycloak | gitea, nextcloud, semaphore, grafana(native) | **Live, working.** Not in scope to change. |
+| **Native/other** | app-specific | seerr (own OIDC), plex | Live. Out of scope. |
+| **forward-auth CEC** (`auth.mode: forward-auth`) | `platform/oauth2-proxy/forward-auth-cec.yaml` — hand-authored `CiliumClusterwideEnvoyConfig` with an `ext_authz` HTTP filter → oauth2-proxy `/oauth2/auth` | jackett, pihole, qbittorrent, radarr, sonarr | **NOT DEPLOYED.** A TEMPLATE, **not** referenced by `platform/oauth2-proxy/kustomization.yaml`. Proven in a throwaway envoy pod (2026-08-28) but never wired. These 5 UIs are currently reachable on the shared Gateway **un-gated**. |
+| **oauth2-proxy sidecar** (per-pod reverse-proxy, "Option B") | `platform/crafty/deployment.yaml` container `oauth2-proxy` (`v7.8.1`, `:4180` → `https://127.0.0.1:8443`) | crafty | **Live, working.** In-data-path fail-closed gate. |
+
+**The renderer contract (`catalog/render.py`):** `auth.mode ∈ {oidc, forward-auth, native, none}`
+(`AUTH_MODES`, line 53); default is `forward-auth` for any app with `ingressRoutes` else `none`
+(lines 76-77). `_auth_annotations()` (line 605) stamps
+`homelab.keithjackson.dev/auth-mode` + `/auth-groups` onto the HTTPRoute for `oidc`/`forward-auth`,
+and pods carry an `auth-mode` label enforced by a Kyverno `require-auth-mode-label` policy
+(R-IDP-02). Since commit `68690e5`, the renderer also emits a `toEndpoints` egress allow to the
+Keycloak backend for `oidc`/`forward-auth` apps (line 539). **No renderer field today expresses an
+ext_authz `backendRef`** — the forward-auth annotations are consumed by the (un-wired) platform
+enforcement, not by a Gateway-API filter.
+
+**Why the CEC exists / why it's not on the Gateway (per its own header + README):** on Cilium 1.16.5
+there was no supported hook to inject `ext_authz` into the machine-regenerated shared-Gateway Envoy
+program, and native ExternalAuth "ships in NO released Cilium version yet (PoC only)." That premise
+is now **partially stale** — see below — which is precisely why this evaluation exists.
+
+---
+
+## Does Cilium 1.20.1 support native Gateway API ExternalAuth? (research)
+
+**Yes, in the code — as an experimental Gateway API feature that is not enabled on this cluster.**
+
+- **Shipped in 1.20.0.** The v1.20.0 release notes list: *"🔐 External Authorization: HTTPRoute
+  requests can now be authenticated and authorized through an external service before they reach the
+  application, using the Gateway API `ExternalAuth` filter from GEP-1494."* (PR
+  [cilium/cilium#45739](https://github.com/cilium/cilium/pull/45739)). Isovalent's 1.20 launch post
+  headlines "Gateway API ExternalAuth."
+- **Shape (GEP-1494 experimental filter).** An HTTPRoute rule gains a filter
+  `type: ExternalAuth` with `externalAuth.protocol: GRPC|HTTP`, a `backendRef` to the auth service,
+  and `grpc.allowedHeaders` / `http.{path,allowedHeaders,allowedResponseHeaders}` / `forwardBody`.
+  It maps onto Envoy's `ext_authz` protocol — the **same** mechanism the hand-authored CEC uses,
+  but declared per-route on the standard shared Gateway instead of a separate listener. Example:
+  ```yaml
+  apiVersion: gateway.networking.k8s.io/v1
+  kind: HTTPRoute
+  spec:
+    rules:
+      - filters:
+          - type: ExternalAuth
+            externalAuth:
+              protocol: GRPC            # or HTTP (oauth2-proxy /oauth2/auth is HTTP)
+              backendRef: { kind: Service, name: oauth2-proxy, port: 80 }
+              http: { path: /oauth2/auth, allowedHeaders: [cookie, authorization] }
+        backendRefs: [{ name: <app>, port: <port> }]
+  ```
+- **It is EXPERIMENTAL-channel.** GEP-1494 status is **Experimental**
+  ([gateway-api.sigs.k8s.io/geps/gep-1494](https://gateway-api.sigs.k8s.io/geps/gep-1494/)). Its
+  fields live only in the Gateway API **experimental** CRD bundle. **This cluster runs the `standard`
+  channel** (verified), so the filter type is not present in the HTTPRoute schema — a manifest using
+  it would be rejected at admission today.
+- **Maturity risk.** Fail-open bug [#47178](https://github.com/cilium/cilium/issues/47178) → fix
+  [#47265](https://github.com/cilium/cilium/pull/47265) (backported to 1.20, ~2026-07-21). Cilium
+  ships **no dedicated ExternalAuth documentation page** in 1.20 (the `/en/v1.20/.../external-auth/`
+  and `/en/latest/.../external-auth/` URLs both 404; the stable Gateway API support page does not
+  mention it). Feature is real but young and thinly documented.
+
+**Bottom line:** the CEC/sidecar READMEs' claim that native ExternalAuth "ships in no released Cilium
+version" is now outdated — it ships in 1.20.x — **but** it is experimental, off by default here
+(wrong CRD channel), and not battle-tested.
+
+---
+
+## Would it cleanly replace the two mechanisms?
+
+**(a) The un-wired forward-auth CEC — YES, in principle, and more cleanly.** This is the strongest
+case for native ExternalAuth: the CEC is a hand-authored TLS listener + routes + EDS clusters on a
+*separate* VIP that requires moving hosts off the shared Gateway and repointing DNS. A native
+`ExternalAuth` filter would instead be one filter block on each app's **existing** HTTPRoute on the
+**existing** shared Gateway/VIP/DNS — no second ingress, no DNS churn, no hand-authored TLS. Since
+the CEC is not deployed, there is **no rip-out risk** here: adopting native ExternalAuth for the 5
+forward-auth apps (jackett/pihole/qbittorrent/radarr/sonarr) would *complete* an unfinished story
+rather than replace a working one. The renderer already carries the `auth-mode`/`auth-groups` signal;
+it would need a new emitter that turns `auth.mode: forward-auth` into the HTTPRoute `ExternalAuth`
+filter (see plan).
+
+**(b) Crafty's sidecar — PARTIAL, and lower value.** Native ExternalAuth could drop the per-pod
+oauth2-proxy container and gate `crafty.home` at the Gateway like the others. **But** Crafty's UI is
+HTTPS **self-signed on :8443**; the sidecar terminates that in-pod (`--ssl-upstream-insecure-skip-
+verify`). Moving the gate to the Gateway means the shared Gateway's Envoy must speak HTTPS to Crafty's
+self-signed `:8443` upstream — requiring a `BackendTLSPolicy` with `insecureSkipVerify` (or a real
+cert), and the `crafty` Service would target `:8443` directly. That is net-new Gateway plumbing to
+remove a small, **working**, fail-closed sidecar. Low priority; do Crafty last, if at all.
+
+Native ExternalAuth **cannot** and **should not** touch the `oidc` apps (gitea/nextcloud/semaphore/
+grafana) — those use in-app OIDC and are out of scope.
+
+---
+
+## Proposed migration plan (do NOT execute now — for review)
+
+Phased, reversible, lowest-blast-radius first. **Precondition gates P1-P3 must clear before ANY
+cluster change.** Each step names the files it touches.
+
+### Phase 0 — Preconditions (research/verify only, no cluster change)
+- **P1. Confirm the fail-open fix is in 1.20.1.** Verify PR #47265 shipped in the running `v1.20.1`
+  (changelog / `git tag --contains`), and reproduce a **fail-closed** ext_authz on a throwaway route
+  (the 2026-08-28 CEC proof, redone with the *native filter* on a scratch HTTPRoute) BEFORE trusting
+  it for R-IDP-02.
+- **P2. Decide the Gateway API channel swap.** Adopting GEP-1494 requires the **experimental** CRD
+  bundle cluster-wide. Assess blast radius (every Gateway/HTTPRoute revalidated against experimental
+  schemas) and reconcile the **Ansible-bootstrap ↔ Flux parity contract** — the Ansible bootstrap
+  that installs Gateway API CRDs must install the *same* channel. Files: wherever the Gateway API CRD
+  bundle is declared for both bootstrap and Flux (search `gateway.networking.k8s.io` CRD source;
+  `platform/gateway/` + the Ansible bootstrap CRD step). This is the single biggest change and its
+  own reviewable sub-plan.
+- **P3. Confirm the Cilium enablement path.** Determine whether Cilium honors the `ExternalAuth`
+  filter on experimental-CRD presence alone or needs an agent/helm flag; if a flag exists it is a
+  `[parity]` value in `platform/cilium/helmrelease.yaml` and the Ansible Cilium values.
+
+### Phase 1 — One canary app (pihole), additive, reversible
+- Install experimental Gateway API CRDs (P2) + any Cilium flag (P3).
+- Add the `ExternalAuth` filter to **pihole's** HTTPRoute only, `backendRef` → `oauth2-proxy`
+  Service, `http.path: /oauth2/auth`, header allow-list mirroring the CEC's proven stanza. Keep
+  `failureMode`/deny semantics fail-**closed**.
+  Files: `catalog/pihole.yaml` (unchanged intent) + a new renderer emitter in
+  `catalog/render.py` (`_httproute()` path) that renders the filter from `auth.mode: forward-auth`;
+  re-render pihole golden. Add the ext_authz **egress allow** to the oauth2-proxy backend for the app
+  (the `enforce_policy_on_l7lb` mitigation, mirroring the Keycloak fix in `render.py`).
+- **Browser test** (the human): incognito `pihole.home` → 302 to Keycloak → login `platform-admins`
+  → PiHole UI; non-`platform-admins` → 403; oauth2-proxy down → **denied**, never the bare UI.
+- **Rollback:** delete the filter block (revert the HTTPRoute) → back to un-gated shared Gateway. No
+  data, no DNS, no VIP involved.
+
+### Phase 2 — Roll out to the remaining forward-auth apps
+- Repeat for jackett, qbittorrent, radarr, sonarr via the renderer (they already declare
+  `auth.mode: forward-auth`; the emitter does it uniformly). Re-render 4 goldens.
+- **Delete `platform/oauth2-proxy/forward-auth-cec.yaml`** and its README section describing the
+  separate-VIP interim — now obsolete. (It was never wired, so this is doc/template cleanup.)
+
+### Phase 3 — Crafty (optional, last)
+- Add `ExternalAuth` to `crafty`'s HTTPRoute; point the `crafty` Service at `:8443`; add a
+  `BackendTLSPolicy` for the self-signed upstream; **remove the oauth2-proxy sidecar** from
+  `platform/crafty/deployment.yaml` and its SOPS creds. Verify game-port L4 path (192.168.1.55)
+  untouched. Higher effort for marginal gain — defer unless consolidating.
+
+---
+
+## Risks & rollback
+
+| Risk | Severity | Mitigation / Rollback |
+|---|---|---|
+| **Fail-open regression** (a new/edge ext_authz bug lets traffic through un-authed — R-IDP-02 violation) | **High** | P1 reproduction on a scratch route before any real app; canary (pihole) first with explicit browser deny-path test; keep un-gated-but-internal apps behind LAN until proven. |
+| **Experimental-channel CRD swap breaks existing Gateways/HTTPRoutes** | **High** | Treat P2 as its own reviewed change; snapshot/backup CRDs; parity with Ansible bootstrap; validate all 16 existing HTTPRoutes still Programmed after the swap. |
+| **`enforce_policy_on_l7lb` blocks the ext_authz hop** (Gateway hairpins to oauth2-proxy backend; NetworkPolicy'd apps 403 the auth check — the CVE-2025-30162 pattern from commit `68690e5`) | **Med-High** | Emit a `toEndpoints` egress allow to the oauth2-proxy backend for forward-auth apps, exactly as done for Keycloak; re-validate the Keycloak egress is not regressed. |
+| **Parity-contract drift** (Flux vs Ansible disagree on CRD channel / Cilium flag) | **Med** | Land CRD-channel + Cilium-flag changes in both bootstrap and Flux in one PR; gate (`make -C ci gate`). |
+| **Thin docs / churn** (experimental API fields change across Gateway API/Cilium minors) | **Med** | Pin bundle version; Renovate watch; keep the CEC template in git history as a fallback recipe. |
+| **Regressing freshly-fixed SSO** | **High** | Do nothing to `oidc` apps; canary + reversible filter-only changes; never touch the shared Gateway CEC directly. |
+
+**Global rollback:** every proposed change is additive at the HTTPRoute level and reverts by removing
+the filter block. The nuclear fallback if native ExternalAuth proves flaky is the **already-proven
+Option B** (per-app oauth2-proxy reverse-proxy, as Crafty uses today) — Gateway-API-native, no CRD
+channel swap, just a `backendRef` to a per-app proxy.
+
+---
+
+## Recommendation
+
+**DEFER.** Native ExternalAuth is the right long-term target and would let us delete both the dead CEC
+template and (eventually) Crafty's sidecar in favor of one uniform, Gateway-API-native filter. But
+**tonight it is not viable**: the enabling CRD channel isn't installed, the feature is experimental
+and recently fail-open-buggy, it is undocumented in 1.20, and it would perturb the shared Gateway and
+the just-fixed `enforce_policy_on_l7lb` egress that SSO now depends on.
+
+Concretely:
+- **Do NOT** adopt now. **Keep** Crafty's working sidecar and leave the 5 forward-auth UIs as-is.
+- **When revisiting** (next maintenance window, not tonight): execute **Phase 0** preconditions,
+  then a **pihole-only canary** (Phase 1). Only after a clean fail-closed browser proof, roll out
+  Phase 2 and retire the CEC template.
+- **Cheaper interim if gating the 5 UIs becomes urgent before then:** adopt **Option B** (per-app
+  oauth2-proxy reverse-proxy, the Crafty pattern) — no experimental CRDs, fully reversible — rather
+  than the separate-VIP CEC or a rushed native-ExternalAuth switch.
+
+This resolves the DECISIONS-LOG open item: **native ExternalAuth is relevant and code-present under
+1.20.1, but blocked on an experimental CRD-channel swap + maturity/fail-open concerns; the interim
+workaround stays.**

+# Cluster upgrade plan — k3s 1.31.5 → 1.36.x + node OS (dev cluster)
+
+> ## ✅ COMPLETED / historical — executed 2026-08-30, see git log
+>
+> **This plan has been carried out.** The dev cluster now runs **k3s v1.36.4+k3s1** on **Debian 13
+> (trixie)** with Cilium 1.20.1 and Longhorn 1.12.1. The steps, gates, and rollbacks below are
+> retained as the record of how the upgrade was performed — do NOT re-execute them against the live
+> cluster. Current state is tracked in `infra/PHASE1-STATUS.md` and the 2026-08-30 DECISIONS-LOG entry.
+
+**Scope:** the `home-network-k3s-impl` **dev** cluster (`k3s-dev-1/2/3` @ 192.168.1.50-52), 3× HA
+embedded-etcd servers behind a kube-vip VIP, Debian 12 bookworm. Upgrade Kubernetes/k3s from
+**v1.31.5+k3s1 → v1.36.x+k3s1** (five minors) and the node OS (Debian 12 → 13), with an
+etcd-snapshot / Velero / CNPG backup gate and explicit PASS/STOP criteria at **every** step, and a
+defined rollback for each hop.
+
+> Status: **PLAN ONLY.** Nothing here has been executed. All version pins marked "confirm at
+> execution" must be re-checked against the upstream release page on the day of the hop — this doc
+> was written 2026-08-29 and homelab component versions move weekly (Renovate).
+
+> Companion runbooks that this plan reuses wholesale:
+> - `docs/plans/ssd-etcd-execution-runbook.md` — the **proven safe-bounce** procedure (Longhorn
+>   rebuild-freeze + one-node-at-a-time + leader-last + per-node verify gates). Every k3s hop below
+>   is a parameterised repeat of that runbook.
+> - `docs/plans/ssd-etcd-isolation.md` — why etcd is fragile on this cluster (slow HDD; etcd now on
+>   a dedicated SSD `virtio2`) and how a single member can be reset+rejoined from the other two.
+

+
+## 0. TL;DR / operator decisions needed
+
+| # | Decision | Recommendation | Needs operator sign-off |
+|---|---|---|---|
+| D1 | k3s upgrade **method** | Scripted **in-place per-node** binary upgrade driven by Ansible, one node at a time, leader-last, with the Longhorn rebuild-freeze. NOT system-upgrade-controller (its auto-drain fights this cluster's slow-HDD Longhorn and removes the human gate between nodes). | **Yes** — SUC vs scripted-in-place |
+| D2 | Node **OS** upgrade | **Immutable re-provision** via tofu (bump the cloud image to Debian 13 trixie, replace one node at a time, rejoin etcd), run as a **separate campaign** from the k3s hops. Not in-place `apt` dist-upgrade. | **Yes** — Debian 13 now, or stay on 12 |
+| D3 | Do OS + k3s on the **same** node bounce? | **No.** Never combine. Finish the k3s ladder to a stable target, then run the OS campaign (or vice-versa), one variable per bounce. | Confirm |
+| D4 | Sequencing granularity | One k3s **minor** per maintenance window (5 windows). Cilium + Longhorn + Gateway-API CRDs advance in **lockstep** inside the same window (they are the pacing blockers). | Confirm |
+| D5 | Flux `image.toolkit.fluxcd.io/v1beta2` → `/v1` migration | **Must** be done before Flux is upgraded to v2.7+ (which is required for k8s 1.36). Do it early, decoupled. | Confirm timing |
+
+**Headline blockers (do these or the hop fails):**
+1. **Cilium 1.16.5 is already at/near its ceiling** — Cilium 1.16 tops out around k8s 1.30-1.31.
+   Cilium **must** step 1.16→1.17→1.18→1.19→1.20 in lockstep with the k8s minors. It is the single
+   most urgent item.
+2. **Longhorn 1.7.3** must step 1.7→1.8→1.9→1.10→1.11→1.12 (one minor at a time) to reach a
+   1.36-validated release (1.12.x).
+3. **Flux v2.4.0 → v2.7+** is required for k8s 1.36, and v2.7 **removed** the image-automation
+   `v1beta2` API the repo still uses.
+4. **KubeVirt v1.9.0 / CDI v1.66.0 are already 1.36-ready** — a pleasant surprise; no VM-stack
+   upgrade needed, just keep them where they are.

+## 2. k3s upgrade path (sequential, one minor at a time)
+
+### 2.1 The path and why skipping is unsafe
+
+```
+1.31.5+k3s1 → 1.32.z → 1.33.z → 1.34.z → 1.35.z → 1.36.z    (+k3s1 each)
+```
+
+**Skipping minors is not supported.** Kubernetes' version-skew policy allows the kube-apiserver and
+components to differ by at most **one minor** during an upgrade, and a downgrade of the etcd
+datastore is not supported. Jumping >1 minor risks an apiserver that can't read objects written by
+an intermediate storage version and control-plane components outside the skew window. On k3s (all
+three nodes are servers/apiserver), the whole control plane moves together per hop, so the rule is:
+**one minor per campaign, all three nodes brought to the same minor before the next.**
+Source: <https://kubernetes.io/releases/version-skew-policy/>.
+
+### 2.2 Target patch per minor (confirm at execution)
+
+Pick the **latest patch of each minor** from <https://github.com/k3s-io/k3s/releases> (or the k3s
+channel server `https://update.k3s.io/v1-release/channels`, where channel `v1.3X` resolves to the
+latest patch of that minor). Known-latest as of writing:
+
+| Hop | Target (min) | Notes / source |
+|---|---|---|
+| → 1.32 | latest `v1.32.z+k3s1` | confirm on releases page |
+| → 1.33 | latest `v1.33.z+k3s1` | k3s 1.33 release notes: <https://docs.k3s.io/release-notes/v1.33.X> |
+| → 1.34 | latest `v1.34.z+k3s1` | confirm |
+| → 1.35 | latest `v1.35.z+k3s1` | confirm |
+| → 1.36 | **`v1.36.3+k3s1`** (Aug 4 2026) or newer (`v1.36.4+k3s1` reported) | <https://docs.k3s.io/release-notes/v1.36.X> |
+
+### 2.3 k3s-specific breaking changes across the path
+
+- **containerd major bump 1.7 → 2.x.** k3s 1.36.3 ships **containerd v2.3.2-k3s2** (current node is
+  1.7.23-k3s2). The containerd v1→v2 migration happens somewhere in the 1.32-1.34 window. It is
+  transparent for standard workloads, but: (a) `config.toml` schema changed — this repo sets
+  `device_ownership_from_security_context` via `--nonroot-devices` (k3s config.yaml), which k3s
+  regenerates into the new containerd config on restart; verify it survives (KubeVirt/CDI Block-mode
+  PVCs depend on it — see `roles/k3s_server/tasks/main.yml`). (b) Any node with custom
+  `/etc/rancher/k3s/config.toml.tmpl` would need review — this cluster has none.
+- **etcd 3.5 → 3.6.** k3s 1.36.3 ships **etcd v3.6.14-k3s1**. etcd datastore version bumps are
+  **one-way** (no downgrade). This is the single strongest reason for the pre-hop etcd snapshot gate
+  (§6) and defines the point-of-no-return (§7).
+- **Traefik chart v40 breaking change** in k3s ≥1.36.2 (ingress-nginx provider rename). **N/A** —
+  this cluster disables Traefik (`k3s_disable: "traefik,servicelb,local-storage"`); Cilium Gateway
+  API owns ingress.
+- **kube-proxy / flannel / network-policy already disabled** (`--disable-kube-proxy`,
+  `--flannel-backend=none`, `--disable-network-policy`) so k8s 1.36's **IPVS-mode kube-proxy
+  deprecation is N/A** — Cilium is the kube-proxy replacement.
+- Always read the **Kubernetes urgent-upgrade notes** for each minor before the hop:
+  <https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/> (`CHANGELOG-1.3X.md` →
+  "Urgent Upgrade Notes").
+
+---
+
+## 3. Removed / deprecated API audit (1.32 → 1.36)
+
+### 3.1 Kubernetes core removals/deprecations per minor
+
+| k8s | Removed / deprecated | Affects this repo? |
+|---|---|---|
+| **1.32** | **`flowcontrol.apiserver.k8s.io/v1beta3`** (FlowSchema, PriorityLevelConfiguration) **removed** — use `flowcontrol.apiserver.k8s.io/v1` (GA since 1.29). Field rename `assuredConcurrencyShares`→`nominalConcurrencyShares`. | **No** — repo defines no FlowSchema/PriorityLevelConfiguration CRs. |
+| **1.33** | `status.nodeInfo.kubeProxyVersion` **field removed** from Node. | **No** — nothing reads it. |
+| **1.34** | **AppArmor** annotations path deprecations continue; `AppArmor` GA'd earlier. | No repo AppArmor annotations. |
+| **1.35** | Minor graduations; no removal that touches this repo's API set. | No. |
+| **1.36** | **`gitRepo` volume permanently disabled**; **Service `externalIPs` deprecated**; **kube-proxy IPVS** on a deprecation clock. | **No** — no gitRepo volumes, no `externalIPs`, kube-proxy already replaced by Cilium. |
+
+Sources: <https://kubernetes.io/docs/reference/using-api/deprecation-guide/> ·
+<https://www.kubernetes.io/blog/2026/03/30/kubernetes-v1-36-sneak-peek/> ·
+per-minor `CHANGELOG-1.3X.md`.
+
+**Conclusion: the repo's manifests use no Kubernetes core API removed in 1.32-1.36.** (Grep for
+`flowcontrol.apiserver`, `gitRepo:`, `externalIPs:`, `policy/v1beta1`, `batch/v1beta1`,
+`autoscaling/v2beta*`, `extensions/v1beta1`, `PodSecurityPolicy` returns **nothing**.)
+
+### 3.2 The one real removal that bites — Flux `image.toolkit.fluxcd.io/v1beta2`
+
+**Flux v2.7+ removed `image.toolkit.fluxcd.io/v1beta2`** (ImageRepository, ImagePolicy,
+ImageUpdateAutomation → graduated to `image.toolkit.fluxcd.io/v1`). Flux v2.7+ is required for k8s
+1.36 (§4.1). The repo still uses `v1beta2` in:
+- `platform/image-automation/image-update-automation.yaml`
+- `platform/image-automation/per-service/pihole.example.yaml`
+(plus any per-service ImageRepository/ImagePolicy generated from that template.)
+
+**Required migration (do BEFORE upgrading Flux to v2.7+):** follow the official
+"Upgrade Procedure for Flux v2.7+" — migrate stored objects off v1beta2, then update every manifest
+in Git from `image.toolkit.fluxcd.io/v1beta2` → `image.toolkit.fluxcd.io/v1`.

+<https://fluxcd.io/flux/components/image/imagerepositories/>.
+
+### 3.3 Detection tooling — run BEFORE each hop
+
+Add a read-only pre-hop gate using **both** a live-cluster scan and a manifest scan:
+
+```bash
+# pluto — scans live cluster AND Helm releases for deprecated/removed apiVersions, target minor
+./infra/devcontainer/dev.sh run bash -lc 'pluto detect-all-in-cluster --target-versions k8s=v1.3X.0 -owide'
+# or scan the rendered manifests in git:
+./infra/devcontainer/dev.sh run bash -lc 'pluto detect-files -d platform -d apps --target-versions k8s=v1.3X.0'
+
+# kubent (kube-no-trouble) — quick live scan
+./infra/devcontainer/dev.sh run bash -lc 'kubent --target-version 1.3X'
+```
+
+- `pluto` and `kubent` detect **built-in** deprecated APIs from their bundled version data; they do
+  **not** know about third-party CRD removals (e.g. the Flux `v1beta2` above) unless given a custom
+  deprecation list. So pair the tool pass with the manual §3.2 check and a `grep` of the repo for
+  each component's deprecated CRD versions before its own upgrade.
+- Neither tool is currently in the toolbox image; add to `infra/devcontainer/Containerfile` +
+  `versions.env`, or run once via `go install`/release binary inside the devcontainer.

+
+### 4.2 The pacing blockers, and the per-hop lockstep
+
+**Cilium and Longhorn are the two items that force the pace** — each supports only ~3-4 k8s minors
+and each upgrades **one minor at a time (no skipping, pre-flight required)**. KubeVirt/CDI are
+already at target, so the VM stack is *not* a blocker this cycle. The mapping:
+
+| Window | k8s target | Cilium (HelmRelease) | Gateway API CRDs | Longhorn (HelmRelease) | Other components landed in this window |
+|---|---|---|---|---|---|
+| **W1** | 1.32 | **1.17** (covers 1.29-1.32) | bump toward Cilium 1.17's required version | **1.8** | — |
+| **W2** | 1.33 | **1.18** (1.30-1.33) | bump | **1.9** | cert-manager→1.18/1.19; kube-prometheus-stack CRDs refresh |
+| **W3** | 1.34 | **1.19** (1.32-1.35) | bump | **1.10** | CNPG→1.28/1.29; Velero→latest |
+| **W4** | 1.35 | 1.19 still covers 1.35 (optional →1.20 early) | as needed | **1.11** | Kyverno→latest; **Flux v1beta2→v1 migration + Flux→v2.7+** |
+| **W5** | 1.36 | **1.20** (1.33-1.36) | **v1.6.x** | **1.12** | cert-manager→1.21; CNPG→1.30; kube-vip→latest; snapshot-controller→latest v8.x |
+
+Ordering rule **inside** each window (critical): **CNI/storage compatibility first, then the k3s
+control-plane hop, then verify.** Concretely per window:
+1. Land the **component** upgrades that must *precede* the new k8s minor (Cilium minor, Gateway API
+   CRDs, Longhorn minor, and any component whose *current* version won't run on the new k8s). Let
+   Flux reconcile; verify healthy on the **still-current** k8s.
+2. Run the **k3s minor hop** (§5) node-by-node.
+3. Verify the components again on the **new** k8s; then land the "opportunistic/loose" bumps.
+
+> Rationale for "Cilium before the apiserver hop": if the apiserver moves to a minor the running
+> Cilium doesn't support, CNI/agent may fail to start on that node and the node never goes Ready.
+> Cilium's own guidance is to run its **pre-flight check** DaemonSet before each Cilium minor bump
+> and to upgrade Cilium **before or alongside** the k8s minor within its supported window.
+
+---
+
+## 5. Upgrade method — evaluation & recommendation (D1)
+
+### 5.1 Options
+
+**(a) Rancher system-upgrade-controller (SUC) with Plans.** Canonical k3s upgrade tool. A `Plan`
+targets nodes by label, concurrency 1, HA-aware, drains → replaces the k3s binary → uncordons.
+- **Pros:** official, declarative, handles server-vs-agent ordering; could live in GitOps.
+- **Cons for THIS cluster:** SUC's default **drain evicts pods**, which on this slow-HDD Longhorn
+  triggers replica **rebuild** storms that starve etcd WAL fsync and flap the VIP — the exact
+  failure `ssd-etcd-isolation.md` documents. You'd have to disable drain (`drain: {enabled:false}`)
+  and still manually apply the Longhorn freeze, at which point SUC's main value (drain automation) is
+  gone. Worse, SUC **automates away the human gate between nodes** — the user's hard requirement is
+  an explicit backup + PASS/STOP verification *between* every node, which SUC does not pause for.
+
+**(b) Scripted in-place per-node binary upgrade (Ansible-driven).** Re-run the k3s install script
+with the new `INSTALL_K3S_VERSION` on one node at a time; k3s replaces its binary and restarts,
+etcd re-joins at the new version. This is exactly the `ssd-etcd-execution-runbook.md` bounce shape.
+- **Pros:** reuses the **proven** freeze + leader-last + per-node-verify pattern; no drain (no
+  rebuild storm — replicas *reattach*); the human gate sits naturally between nodes; minimal moving
+  parts. **Note the `creates:` guard:** the existing install task self-skips on a running node, so
+  the upgrade path must invoke the install script *explicitly* (a dedicated play/tag, or an ad-hoc
+  `curl … | INSTALL_K3S_VERSION=<tag> sh -s - server`), not rely on bumping the var alone.
+- **Cons:** does not touch the OS (handled separately, §6/D2); slightly more manual than SUC.
+
+**(c) Immutable re-provision via tofu.** Bump `image_source` + `k3s_version`, `tofu replace` one VM
+at a time, node rejoins etcd fresh and Longhorn rebuilds that node's replicas.
+- **Pros:** **also solves the OS upgrade** in the same motion; clean, reproducible cattle nodes.
+- **Cons:** destroys the node's etcd member + **all** its Longhorn replicas → full **rebuild** (not
+  reattach) on the slow HDD per node (throttled but heavy, ~hours for 18 volumes' replicas across
+  three rebuilds); the etcd SSD `virtio2` is wiped on replace (fine for a 3-node HA etcd — the new
+  member syncs from the other two). Heavier and slower than (b) for a *pure k8s* hop.
+
+### 5.2 Recommendation
+
+- **k3s minor hops (W1-W5): choose (b), scripted in-place per-node.** It matches the cluster's
+  proven safe-bounce, avoids rebuild storms, and preserves the mandatory per-node human gate. Pin
+  the new tag in `roles/k3s_server/defaults/main.yml` (`k3s_version`) **and** drive the actual
+  upgrade with an explicit install-script invocation (bypassing the `creates:` guard), `serial: 1`,
+  leader-last.
+- **Node OS (Debian 12→13): choose (c), immutable re-provision**, as a **separate** campaign (§8).
+  A clean trixie image beats an in-place `apt` dist-upgrade for reproducibility, and the nodes are
+  already cattle (cloud-init + `node_baseline` rebuild them). Accept the per-node Longhorn rebuild
+  there (that campaign *wants* rebuild, throttled at limit=1, since replicas are genuinely gone).
+- SUC remains a reasonable future option **once the cluster is on fast disks** (the prod/mini-PC
+  Phase-7 cluster) where drain-driven rebuild is cheap; note it for later.
+

+
+## 6. Data-validation gates at EVERY step (hard requirement)
+
+Every **node bounce** (there are 3 per k3s window; 3 per OS window) is wrapped by a pre-step backup
+gate and a post-step verification gate. Every **window** additionally takes a full cluster backup
+before the first node.
+
+### 6.1 PRE-STEP backup gate (before the first node of a window, and re-confirm before each node)
+
+```bash
+# 1) etcd on-demand snapshot (k3s native) — the primary rollback artifact. Run on the leader.
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible <leader> -b -m shell \
+  -a "k3s etcd-snapshot save --name pre-1.3X-$(date +%Y%m%d%H%M)"'
+# verify it exists + is copied off-node (snapshots land in /var/lib/rancher/k3s/server/db/snapshots;
+# also archived to S3 if configured). Confirm size > 0 and note the name.
+
+# 2) Velero backup (cluster resources + PVC data via kopia FSB → MinIO 192.168.1.9:9000)
+./infra/devcontainer/dev.sh run bash -lc 'velero backup create pre-1.3X-$(date +%Y%m%d%H%M) --wait'
+./infra/devcontainer/dev.sh run bash -lc 'velero backup describe <name> --details'   # Phase=Completed, 0 errors
+
+# 3) CNPG logical backup + verify, for each of keycloak-db / nextcloud-db / semaphore-db
+#    (they already run continuous WAL + daily base backups to MinIO via barmanObjectStore).
+#    Trigger an on-demand base backup and confirm it completes:
+./infra/devcontainer/dev.sh run kubectl -n <ns> create -f - <<'EOF'
+apiVersion: postgresql.cnpg.io/v1
+kind: Backup
+metadata: { name: pre-upg-<ns>, namespace: <ns> }
+spec: { method: barmanObjectStore, cluster: { name: <cluster> } }
+EOF
+./infra/devcontainer/dev.sh run kubectl -n <ns> get backup pre-upg-<ns> -o jsonpath='{.status.phase}'  # completed
+# capture an integrity baseline to compare after:
+./infra/devcontainer/dev.sh run kubectl -n <ns> exec <cluster>-1 -- psql -tAc \
+  "select (select count(*) from pg_database), (select sum(('x'||substr(md5(t.oid::text),1,8))::bit(32)::bigint) from pg_class t)"
+```
+
+**PASS to proceed:** etcd snapshot present (>0 bytes, name recorded) **AND** Velero backup
+`Completed` with 0 errors **AND** all three CNPG on-demand backups `completed` with baseline
+captured.
+**STOP (do not start the hop):** any backup fails, errors, or cannot be verified restorable.
+
+### 6.2 The per-node bounce itself (reuse `ssd-etcd-execution-runbook.md`)
+
+Per node `NODE=k3s-dev-N`, `VMID`, **leader last** (re-verify leader before each node):
+
+```bash
+# leader check
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s_servers -m shell \
+  -a "curl -s http://127.0.0.1:2381/metrics | grep etcd_server_is_leader"'
+
+# 1) FREEZE Longhorn rebuilds (reattach, not rebuild) — the proven safe-bounce
+./infra/devcontainer/dev.sh run kubectl -n longhorn-system patch settings.longhorn.io \
+  concurrent-replica-rebuild-per-node-limit --type=merge -p '{"value":"0"}'
+
+# 2) Upgrade k3s ON THIS NODE ONLY (explicit install, bypassing the creates: guard):
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible $NODE -b -m shell \
+  -a "curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.3X.z+k3s1 sh -s - server"'
+#    (k3s replaces its binary and restarts; embedded etcd re-joins at the new version)
+
+# 3) VERIFY this node fully before touching the next (see §6.3), THEN
+# 4) THAW rebuilds only after 18/18 healthy:
+./infra/devcontainer/dev.sh run kubectl -n longhorn-system patch settings.longhorn.io \
+  concurrent-replica-rebuild-per-node-limit --type=merge -p '{"value":"1"}'
+```
+
+### 6.3 POST-STEP verification gate (after each node; full set after the last node of a window)
+
+```bash
+./infra/devcontainer/dev.sh run kubectl get nodes -o wide            # NODE Ready, VERSION = new minor
+./infra/devcontainer/dev.sh run kubectl get --raw=/readyz/etcd       # ok
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s_servers -m shell \
+  -a "curl -s http://127.0.0.1:2381/metrics | grep etcd_server_has_leader"'   # all = 1
+./infra/devcontainer/dev.sh run kubectl -n longhorn-system get volumes.longhorn.io \
+  -o custom-columns=R:.status.robustness --no-headers | grep -c healthy       # 18
+./infra/devcontainer/dev.sh run kubectl -n kube-system rollout status ds/cilium --timeout=300s
+./infra/devcontainer/dev.sh run bash -lc 'flux get kustomizations -A && flux get helmreleases -A'  # all Ready
+# etcd snapshot restorability spot-check (list; a scratch restore is the W-level drill, §7)
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible <leader> -b -m shell \
+  -a "k3s etcd-snapshot ls"'
+# CNPG integrity vs the §6.1 baseline
+./infra/devcontainer/dev.sh run kubectl -n <ns> exec <cluster>-1 -- pg_isready         # accepting connections
+# re-run the row-count/checksum query and diff against baseline (must match)
+```
+
+**App smoke tests (the QA-sweep URL set)** — after each *window* completes, expect HTTP 200/302
+(or the app's healthy code) from:
+`auth` · `crafty` · `gitea` · `grafana` · `headlamp` · `jackett` · `keycloak`
+(`/realms/homelab/.well-known/openid-configuration`) · `nextcloud` · `pihole` · `plex` ·
+`qbittorrent` · `radarr` · `seerr` · `semaphore` · `sonarr` · `unifi` — all under
+`*.home.keithjackson.dev`. Plus one KubeVirt VM check (a VMI Running / console reachable).
+
+**PASS to advance to the next node/window:** all nodes Ready at the expected version · etcd
+`/readyz/etcd`=ok and 3/3 have a leader · **18/18** Longhorn healthy (reattached, no rebuild storm)
+· Cilium DaemonSet rolled out · all Flux Kustomizations + HelmReleases Ready · CNPG `pg_isready` +

+
+## 7. Rollback per step & point-of-no-return
+
+### 7.1 Per-node (before etcd majority is on the new minor)
+
+The safest rollback for a single bad node is to **re-pin the old k3s version on that node** and
+re-run the install script for the old tag, then verify it rejoins at the old minor; or reset the
+member and rejoin from the other two (2/3 quorum holds), per `ssd-etcd-isolation.md` §4.5. Because
+you go **leader-last and one node at a time**, at any moment ≤1 node is on the new minor until the
+2nd node upgrades.
+
+### 7.2 Point-of-no-return per hop
+
+**When the *second* server reaches the new minor, etcd majority (2/3) is on the new datastore
+version** (etcd 3.5→3.6 across the path is one-way). Past that point, "roll back the node" is no
+longer enough — a true rollback is an **etcd snapshot restore** of the whole cluster to the pre-hop
+snapshot:
+
+```bash
+# cluster-wide restore from the pre-hop snapshot (DISRUPTIVE — full control-plane stop):
+# on ONE server, with k3s stopped on all three:
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s_servers -b -m shell -a "systemctl stop k3s"'
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible <node1> -b -m shell \
+  -a "k3s server --cluster-reset --cluster-reset-restore-path=/var/lib/rancher/k3s/server/db/snapshots/<pre-1.3X-snap>"'
+# then wipe db on the other two and rejoin them (standard k3s cluster-reset-restore flow),
+# and PIN k3s_version back to the old tag before they re-join.
+```
+
+After an etcd restore, **Longhorn volume data is recovered by Velero (kopia FSB) / CNPG PITR** for
+anything written between snapshot and restore — this is why the §6.1 triad (etcd + Velero + CNPG)
+is mandatory, not just etcd.
+
+### 7.3 Window-level DR drill (do once, in W1, to prove the path)
+
+Before the first real hop, prove restorability end-to-end: `velero restore create --from-backup
+<pre-snap> --namespace-mappings <ns>:<ns>-scratch` into a scratch namespace and confirm data lands
+(this is the existing Phase-4 R-STATE-03 gate). If the drill fails, **do not begin the upgrade.**
+
+### 7.4 OS-campaign rollback
+
+Re-provision is inherently reversible per node: if a re-provisioned trixie node misbehaves,
+`tofu` re-apply with `image_source` reverted to bookworm re-creates it on Debian 12; the node
+rejoins etcd and rebuilds replicas as with any replacement. Point-of-no-return is the same etcd
+majority rule if OS re-provision is (against advice) combined with a k3s bump — which is why D3 says
+keep them separate.
+
+---
+
+## 8. Node OS upgrade — Debian 12 → 13 (trixie)
+
+- **Debian 13 "trixie" released 2025-08-09, ships Linux 6.12 LTS** (up from bookworm's 6.1).
+  Support to 2028-08 (LTS 2030-08). Sources: <https://www.debian.org/News/2025/20250809> ·
+  <https://www.debian.org/releases/trixie/>.
+- **Kernel implications (positive):** 6.12 is newer than Cilium's/Longhorn's minimums and improves
+  eBPF/BPF feature coverage for Cilium and has current `iscsi_tcp`/`nfs`/`dm_crypt`/`overlay`/
+  `br_netfilter` modules Longhorn needs (all already pinned in
+  `roles/node_baseline/defaults/main.yml` → `node_baseline_kernel_modules`). No known regression for
+  this stack; `open-iscsi`/`nfs-common` packages exist on trixie.
+- **Method (D2): immutable re-provision.** Bump `infra/tofu/variables.tf`:
+  - `image_source` → `https://cloud.debian.org/images/cloud/trixie/latest/debian-13-generic-amd64.qcow2`
+  - `image_file_name` → `debian-13-generic-amd64.qcow2`
+  Then `tofu apply -replace=proxmox_virtual_environment_vm.node["k3s-dev-N"]` **one node at a time**,
+  let `node_baseline` + `k3s_server` (secondary/join) rebuild it, and let it rejoin etcd. Because a
+  replaced node loses its Longhorn replicas, run this campaign with rebuild **throttled at 1** (not
+  frozen at 0 — you *want* the rebuild here), wait for 18/18 healthy before the next node, and keep
+  the same per-node backup + verify gates (§6).
+- **Coordinate with k3s (D3):** run the OS campaign **after** the cluster is stable on a chosen k3s
+  minor (either finish the whole 1.36 ladder first, or interleave one full campaign between k3s
+  windows) — **never** re-provision to trixie *and* bump k3s in the same node bounce; that entangles
+  two failure domains and defeats per-step rollback.
+- **In-place `apt` dist-upgrade** is the fallback if re-provision is undesirable, but it is discarded
+  here: it mutates cattle nodes outside the tofu/cloud-init source of truth, risks half-migrated
+  states across three nodes, and violates the repo's "changes go through IaC" principle.
+
+---
+
+## 9. Sequencing & HA safety
+
+- **Quorum:** 3 servers, embedded etcd, quorum 2/3. Exactly **one** node down at a time keeps
+  quorum. Never bounce two simultaneously.
+- **Leader last:** re-verify the etcd leader before each node (`etcd_server_is_leader` on :2381) and
+  upgrade followers first, leader last, so leadership only moves once and late.
+- **VIP stability:** kube-vip floats 192.168.1.49 to the current leader; with one node down the VIP
+  fails over to a surviving leader and the API stays reachable through the pfSense NAT
+  (192.168.2.50:6443). Watch for VIP flapping as a STOP signal.
+- **Rebuild-freeze (reattach, not rebuild):** for k3s in-place hops set
+  `concurrent-replica-rebuild-per-node-limit=0` around each bounce so a briefly-down node's replicas
+  **reattach** instead of triggering a rebuild storm that starves etcd WAL fsync (the whole reason
+  etcd is on a dedicated SSD). Thaw to `1` only after 18/18 healthy. (For the OS re-provision
+  campaign use `1`, not `0`, since replicas are genuinely gone and must rebuild.)
+- **CNPG note:** all three DBs are **single-instance** (`instances: 1`) — each incurs a brief
+  outage when its pod reschedules during a node bounce. Order/announce accordingly; the app
+  smoke-tests (§6.3) will blip while a DB pod moves. (Consider `instances: 3` for the prod cluster.)
+- **KubeVirt/CDI:** already 1.36-ready; VMs without `evictionStrategy: LiveMigrate` simply
+  Evict+restart on a node bounce (we do **not** drain in method (b), so VMs are only affected on
+  the node actually bouncing).
+
+**Estimated maintenance windows:** per k3s minor ≈ **60-120 min** (3 nodes × ~15-30 min bounce +
+verify + freeze/thaw + component reconcile), so **5 windows ≈ 5-10 h** total spread across days,
+plus the W-level backups. OS re-provision campaign ≈ **2-4 h per node** (dominated by Longhorn
+rebuild of that node's share of 18 volumes on HDD) → ~1-1.5 days, one node per session.
+
+---
+
+## 10. Dev-first, then prod (Phase-7 carry-over)
+
+This dev run is the rehearsal for the eventual **prod / mini-PC** cluster. What carries over:
+- The **method** (scripted in-place per-node for k3s; immutable re-provision for OS), the
+  **leader-last + freeze + per-node-gate** discipline, and the **backup triad** gate are
+  cluster-agnostic and become the prod runbook verbatim.
+- The **component lockstep table** (§4.2) is the reusable dependency map; re-confirm exact patch
+  numbers at prod time (they will have moved).
+- **Differences to expect on prod:** fast disks (NVMe/SSD) make Longhorn rebuild cheap → **SUC
+  becomes viable** there (drain no longer dangerous), and multi-instance CNPG (`instances: 3`)
+  removes the single-DB outage blip. Prod may also run dedicated workers, changing SUC Plan
+  server-vs-agent ordering.
+- The **Flux v1beta2→v1 migration** (§3.2) is a one-time repo change shared by both clusters — do it
+  once, both benefit.

+# L2/L3 conformance CI wiring — implementation plan
+
+**Status:** PLAN — deferred, awaiting operator decision on the trigger-credential model. No
+cluster changes made.
+**Author:** WS-GITOSS agent, 2026-08-31 (Hand-off 2).
+**Scope:** wire the L2 (behavioural) + L3 (fault-injection) conformance layers into the LIVE
+Gitea Actions merge gate, running them as an **in-cluster Chainsaw Job** so CI holds **no broad
+kubeconfig** (docs/14 "Where each layer runs", ADR-0011, R-SEC-02).
+
+> This companions the landed Hand-off 1 (commit `27bc024`: `make -C ci gate` parity + the
+> comment-only R-ID scan fix). The `conformance` job in `.gitea/workflows/gate.yml` is still an
+> honest `if: false` placeholder — this plan is what turns it on **safely**.
+
+---
+
+## 1. Why this is a written plan, not a landed change
+
+The intended seam is real and mostly scaffolded, but finishing it autonomously would mean
+handing a shared, **live** cluster a new privileged identity reachable from CI, plus building
+several missing functional pieces. The hand-off's rule is explicit: *if wiring real cluster
+access from CI is too risky/ambiguous to finish autonomously, STOP and write a concrete plan —
+do NOT hand CI a broad kubeconfig.* The blocker is a genuine **privilege-escalation** design
+question (§4), not just plumbing, and the cluster is being changed concurrently by sibling
+agents. So the credential model must be decided by the operator before anything is applied.
+
+---
+
+## 2. Current state (what exists today)
+
+| Piece | File | State |
+|---|---|---|
+| Live gate workflow | `.gitea/workflows/gate.yml` | LIVE. `gate` job runs `make -C ci gate`. `conformance` job is `if: false` placeholder. |
+| Dormant full blueprint | `.gitea/workflows/merge-gate.yaml` | Shows the intended shape: `conformance` job `if: ${{ vars.CLUSTER_AVAILABLE == 'true' }}`, `secrets.CONFORMANCE_TRIGGER_KUBECONFIG`, `make -C ci conformance`, then a `merge-gate` decision job (`scripts/decide.sh`). Manual-only (`workflow_dispatch`). |
+| CI conformance stage | `ci/conformance.sh` | SKIPS (exit 3) unless `CLUSTER_AVAILABLE=true`. When "on", it currently runs `conformance/run.sh --layer l2,l3` **locally in the CI job** and collects `_artifacts/`. Its own header carries `TODO(Phase 1): drive the in-cluster Chainsaw Job under the narrow CONFORMANCE_TRIGGER_KUBECONFIG` — i.e. the trigger path is **not implemented**. |
+| Conformance runner | `conformance/run.sh` + `conformance/lib/`, `conformance/tests/` | Works locally/in-cluster. `--layer l2,l3 [--requirements ...]`, writes `_artifacts/report.junit.xml` + `coverage/`. Needs bash + python3 + chainsaw (+ kubectl for `conf_cluster_reachable`). |
+| In-cluster Job skeleton | `conformance/incluster/chainsaw-job.yaml` | Skeleton: `generateName: conformance-run-`, ns `conformance`, `serviceAccountName: conformance-runner`, image `ghcr.io/kyverno/chainsaw:v0.2.12`, `command: ["./run.sh"]`, args default `--layer all --strict-coverage`. **`workspace` is an empty `emptyDir` with no init-container to populate it**, and `results` is an `emptyDir`. |
+| Scoped runner RBAC | `conformance/incluster/rbac.yaml` | ns `conformance` + SA `conformance-runner` + a **privileged** ClusterRole (namespaces create/delete/patch, pods+pods/exec, jobs create/delete, **nodes get/list/patch** for R-STATE-02 cordon, pods/log). Least-privilege, per-test-justified. **Not reconciled by Flux** (no kustomization references `conformance/incluster/`). |
+| Runner deployment | `apps/wave-1/gitea-actions.yaml` | act_runner + DinD (Docker executor). **`automountServiceAccountToken: false`** — the runner and its job containers hold NO SA token. Broad egress allowed (`- {}`), so it can *reach* the kube-API VIP `192.168.1.49:6443`, but has no credential. |
+| Secrets encryption | `.sops.yaml` (repo root) | age recipient `age175l8m…mfzg`; encrypts `data`/`stringData` of `*.sops.yaml` under `platform|apps|catalog/**` and `secrets/**`. Private key is the in-cluster `sops-age` Secret Flux uses. |
+
+**Cluster reality:** the "Phase 0 / no cluster" language in these files is stale — the dev cluster
+is LIVE (Phase 6). So `CLUSTER_AVAILABLE` is the only remaining gate, exactly as the blueprint says.
+
+---
+
+## 3. Gaps to close (functional)
+
+1. **Runner image.** `ghcr.io/kyverno/chainsaw` is a minimal image; `run.sh` needs **bash +
+   python3 + chainsaw + kubectl**, and the repo-clone init needs **git**. The Job cannot run
+   `./run.sh` on the stock chainsaw image. → Build a pinned `conformance-runner` image (chainsaw
+   `v0.2.12` + kubectl `v1.36.4` + git + python3 + bash), push to the Gitea container registry,
+   pin its digest in `conformance/versions.env` (`CONFORMANCE_RUNNER_IMAGE`). Keep
+   `CHAINSAW_VERSION` as the single source of truth the image is built from.
+2. **Repo at the commit-under-test.** The Job must run the suite at the PR head SHA. → Add an
+   **init-container** (`git clone --depth 1` of the impl repo, then `git checkout <SHA>`) writing
+   into the shared `workspace` volume, using a **read-only** Gitea deploy token. SHA + the touched
+   `--requirements` are injected by the CI trigger step as Job env/args.
+3. **Results collection without giving CI exec/cp.** The Job writes `_artifacts/` to the `results`
+   volume; CI holds only trigger/read rights (§4). → Job's last step prints a delimited
+   base64 tar of `_artifacts/` to stdout (`=== ARTIFACTS-TGZ-BASE64 ===`…); CI decodes it from
+   `kubectl logs`. No `pods/exec`, no `kubectl cp`, no results PVC exposure required. (A results
+   PVC + a read-only sidecar is the durable alternative if log size becomes a problem.)
+4. **`ci/conformance.sh` rewrite.** Replace the local `run.sh` call with: render the Job manifest
+   (inject image digest, SHA, `--requirements <touched>`), `kubectl --kubeconfig=$CONFORMANCE_TRIGGER_KUBECONFIG
+   -n conformance create -f -`, `kubectl wait --for=condition=complete/failed`, stream logs,
+   decode artifacts into `results/junit` + `reports/coverage`, map Job success→0 / failure→1 /
+   no-cred→3 (skip). Keep the touched-subset selection it already computes.
+5. **Flux wiring.** Reconcile `conformance/incluster/` (ns + `conformance-runner` SA/RBAC + the
+   new trigger SA/Role + the admission policy of §4) via a **non-gating** Kustomization
+   (`wait:false`, `dependsOn: platform-config`), mirroring `apps-vms` — a conformance identity
+   must never gate the app tier.
+6. **Gitea provisioning (operator, out-of-GitOps).** Set repo/org `vars.CLUSTER_AVAILABLE=true`
+   and `secrets.CONFORMANCE_TRIGGER_KUBECONFIG` via the Gitea API
+   (`PUT /repos/{owner}/{repo}/actions/{variables,secrets}/{name}`). The kubeconfig embeds the
+   trigger SA's token only. SOPS-seal the SA token in-repo (`secrets/conformance-trigger.sops.yaml`)
+   for reproducibility/rotation; the Gitea secret is derived from it.
+
+---
+
+## 4. The security crux — trigger credential must NOT grant `conformance-runner`'s power
+
+**Problem.** Kubernetes places no `use` check on a Pod/Job's `serviceAccountName` at creation.
+So **any principal that can `create jobs` in namespace `conformance` can create a Job with
+`serviceAccountName: conformance-runner` and an arbitrary `command`** — i.e. run arbitrary code
+with the privileged runner SA (nodes/patch, pods/exec, jobs, namespaces/patch). A CI-held token
+with plain `create jobs` therefore *is* the privileged identity. That breaks R-SEC-02 ("CI holds
+no broad cluster access") even though the token's RBAC "looks" narrow.
+
+**Recommended model — narrow trigger SA + an admission constraint (uses the existing Kyverno L0
+stack):**
+
+- SA `conformance-trigger` (ns `conformance`), Role: `create` on `jobs`; `get,list,watch` on
+  `jobs`; `get` on `pods` and `pods/log`. Nothing else. Bound only in the `conformance` ns.
+- A **Kyverno ClusterPolicy (validate, enforce, fail-closed)** that, *for Jobs created by
+  `system:serviceaccount:conformance:conformance-trigger`*, ADMITS only Jobs that match the
+  committed shape: image == the pinned `CONFORMANCE_RUNNER_IMAGE` digest,
+  `serviceAccountName == conformance-runner`, `command == ["./run.sh"]`, `args` matching
+  `^--(layer|requirements|strict-coverage)`, `securityContext` non-root/no-privilege/no host
+  namespaces, and no extra volumes beyond `workspace`/`results`. Any other Job from that SA is
+  DENIED. This is the real security boundary: it bounds CI to "run exactly the committed
+  conformance suite, nothing else." (Equivalent: a k8s ValidatingAdmissionPolicy bound to that SA.)
+- The `chainsaw-conf-*` per-test namespaces the runner creates are already flagged in
+  `rbac.yaml` as needing exclusion from any cluster-wide disallow-privileged/host-namespaces
+  policy for R-NET-06 — carry that exception through, documented and audited.
+
+**Alternative model — GitOps-native, zero CI cluster credential (more work, strongest):** CI does
+not reach the cluster at all. A `ConformanceRun` marker (a CR or a commit to a watched path) is
+reconciled by an in-cluster controller/Flux that creates the Job from the in-repo template; the
+Job publishes results back as a Gitea commit-status / a fetchable artifact that CI polls. Removes
+the trigger credential entirely, at the cost of a controller and a trigger/ordering mechanism that
+must complete before the merge decision. Recommended only if even the constrained trigger SA of
+the primary model is deemed unacceptable.
+
+**Do NOT:** give CI a `cluster-admin`/broad kubeconfig; give the trigger SA unconstrained
+`create jobs`; mount an SA token into the act_runner pod; or reuse `conformance-runner` as the
+trigger identity.
+
+---
+
+## 5. Concrete step sequence
+
+Land these as separate reviewable PRs, gate-green at each step. Steps 1–5 are in-repo/GitOps and
+safe to land incrementally *without* turning L2/L3 on; only step 7 (the operator setting the Gitea
+var) actually enables it.
+
+1. **Runner image.** `conformance/incluster/Containerfile` (chainsaw+kubectl+git+python3+bash);
+   build+push to the Gitea registry; pin `CONFORMANCE_RUNNER_IMAGE=<registry>/conformance-runner@sha256:…`
+   in `conformance/versions.env`. Add a note tying it to `CHAINSAW_VERSION`.
+2. **Job manifest.** Rewrite `chainsaw-job.yaml`: swap to `CONFORMANCE_RUNNER_IMAGE`; add the
+   git-clone init-container (SHA + repo URL + read token env); parametrise `args` (CI injects
+   `--layer l2,l3 --requirements <touched>`); keep `restartPolicy: Never`, `backoffLimit: 0`,
+   non-root/seccomp/readonly-rootfs; add sane CPU/mem requests+limits (heavy L3 etcd load —
+   see `run.sh` HEAVY set + `config/chainsaw-config.yaml`).
+3. **Trigger SA/RBAC + admission policy.** Add `conformance-trigger` SA + Role/RoleBinding to
+   `rbac.yaml`; add the Kyverno ClusterPolicy (new file under `platform/kyverno/` or
+   `conformance/incluster/`) constraining that SA's Jobs (§4). Add an L0 Kyverno test fixture for
+   the policy (admit the good Job, deny a tampered one) so `make -C ci l0` covers it.
+4. **Flux Kustomization.** New `clusters/<cluster>/conformance.yaml` (or an `apps-conformance`
+   entry) — `wait:false`, `dependsOn: platform-config`, `prune:true`, pointing at
+   `conformance/incluster/`. No `postBuild.substituteFrom` unless needed. Verify it reconciles
+   Ready with the SA/RBAC/policy present and NO Job running (Jobs are created only on trigger).
+5. **`ci/conformance.sh` rewrite.** Implement the trigger→wait→collect→map flow of §3.4 behind
+   `CONFORMANCE_TRIGGER_KUBECONFIG`; keep exit 3 when the cred is absent (honest skip). Update
+   `ci/README.md`. `make -C ci gate` still SKIPS L2/L3 locally (no cred) — unchanged for humans.
+6. **Workflow.** Replace the `if: false` placeholder in `gate.yml`'s `conformance` job with the
+   blueprint shape: `if: ${{ vars.CLUSTER_AVAILABLE == 'true' }}`, `needs: [gate]`, install the
+   `conformance` toolchain, `env: CONFORMANCE_TRIGGER_KUBECONFIG: ${{ secrets.CONFORMANCE_TRIGGER_KUBECONFIG }}`,
+   `run: make -C ci conformance`. Decide: either keep the single-`gate` model (aggregate `gate.sh`
+   already SKIPS conformance and reports UNVERIFIED) and add conformance as a **second required
+   check**, or adopt the blueprint's separate `merge-gate` decision job (`scripts/decide.sh`).
+   Keep the job honest: skipped when the var is off, never faked green (HARD RULE 4). Add the
+   conformance check to branch protection only after step 7 proves it green.
+7. **Enable (operator).** Provision the SOPS-sealed trigger SA token; set the Gitea
+   `secrets.CONFORMANCE_TRIGGER_KUBECONFIG` and `vars.CLUSTER_AVAILABLE=true`. First run on a
+   throwaway PR; confirm the Job is created, runs the touched subset, results are collected, and
+   the gate blocks on a real L2/L3 failure and passes on green. Then make it required.
+
+---
+
+## 6. Validation & rollback
+
+- **Dry-run the admission policy** before granting the trigger SA: `kubectl auth can-i` matrix for
+  `conformance-trigger`; attempt a *tampered* Job (different command) as that SA and confirm
+  Kyverno DENIES it; attempt the committed Job and confirm ADMIT.
+- **Fail-closed check:** temporarily break an L3 test, confirm the Job fails and the gate BLOCKS
+  (mirrors Hand-off 1's proof that `gate.sh` exit 1 fails the job).
+- **Rollback:** unset `vars.CLUSTER_AVAILABLE` (instant SKIP, gate reverts to L0/L1-only) and/or
+  suspend the Flux Kustomization; delete the trigger SA token from Gitea secrets. No app-tier
+  impact (conformance is a non-gating tier).
+
+---
+
+## 7. Open decisions for the operator
+
+1. **Trigger model:** constrained trigger SA + Kyverno admission policy (§4 primary) vs.
+   GitOps-native zero-credential (§4 alternative). This plan recommends the primary.
+2. **Runner image host:** Gitea container registry (in-network, matches the Flux source loop) vs.
+   ghcr.io. Recommend Gitea registry, digest-pinned.
+3. **Gate topology:** conformance as a second required check on the single-job `gate.yml` vs.
+   restoring the blueprint's multi-job `merge-gate.yaml` with the `decide.sh` decision job.
+4. **Results transport:** base64-tar-over-logs (simple, no extra rights) vs. a results PVC +

+# Longhorn SSD tiering for the k3s dev cluster
+
+**Status:** PROPOSAL — awaiting user approval. No storage, tofu, Longhorn, or live
+infrastructure has been changed. This is a read-only investigation + reviewable plan.
+**Author:** investigation agent (read-only), 2026-08-31
+**Problem:** All 18 Longhorn data volumes live on the slow/failing Seagate-class HDD
+pool (`Storage`). Every node reboot marks that node's replicas stale and triggers a
+full 18-volume rebuild that spikes Proxmox IO-delay to 30 %+ and runs for a long time,
+making every upgrade / resize / reboot expensive and risky. etcd was already isolated
+onto a dedicated per-node SSD disk (`virtio2`, `local-zfs`) for exactly this reason
+(`docs/plans/ssd-etcd-isolation.md`). The recorded blocker was that the SSD "does not
+fit" the 3 × 128 GiB Longhorn data disks, so Longhorn stayed on HDD "interim until the
+all-SSD mini-PCs land."
+
+**Verdict (short):** The "doesn't fit" blocker was computed against the **provisioned**
+128 GiB disks. The **actual working set is ~26 GB per node (~79 GB across all three
+nodes)** — bulk media is on NFS, *not* Longhorn, so every Longhorn volume is a small
+config/DB volume. **A hot-tier move onto SSD is viable and recommended**; a full move
+is also feasible on space but re-couples rebuild I/O with etcd/host on the same SSD
+pool. Recommendation: **Phase 1 hot-tier move (Prometheus + the CNPG DBs + Loki +
+gitea) onto a tagged `longhorn-ssd` disk**, one node at a time.
+

+
+## 1. Measured facts (all collected read-only, 2026-08-31)
+
+### 1.1 The Longhorn working set — provisioned vs *actual*
+
+`kubectl -n longhorn-system get volumes.longhorn.io` — capacity (`spec.size`) vs
+**actual consumed** (`status.actualSize`, the real on-disk footprint of one replica,
+snapshots included). All 18 volumes are `numberOfReplicas: 3`, so each node holds one
+replica of each and a node's on-disk footprint ≈ the actualSize column below.
+
+| Volume / PVC | Namespace | App class | Provisioned | **Actual (per replica)** | Tier |
+|---|---|---|---:|---:|---|
+| prometheus-…-db-0 | monitoring | Prometheus TSDB | 8 GiB | **11.59 GB** | HOT |
+| unifi-rootdisk | unifi | KubeVirt VM disk (`longhorn-vm`) | 40 GiB | 6.20 GB | cold |
+| nextcloud-data | nextcloud | file data | 20 GiB | 1.44 GB | cold |
+| nextcloud-db-1 | nextcloud-db | CNPG Postgres | 5 GiB | 1.41 GB | HOT |
+| storage-loki-0 | monitoring | Loki chunks/index | 5 GiB | 1.24 GB | HOT |
+| keycloak-db-1 | keycloak | CNPG Postgres | 5 GiB | 0.93 GB | HOT |
+| gitea-data | gitea | git repos + SQLite/meta | 10 GiB | 0.90 GB | HOT |
+| semaphore-db-1 | semaphore-db | CNPG Postgres | 5 GiB | 0.79 GB | HOT |
+| crafty-data | crafty | Minecraft world | 20 GiB | 0.54 GB | cold |
+| plex-config | plex | Plex metadata/db | 8 GiB | 0.23 GB | cold |
+| seerr-config | seerr | config | 5 GiB | 0.17 GB | cold |
+| sonarr-config | sonarr | config db | 5 GiB | 0.15 GB | cold |
+| qbittorrent-config | qbittorrent | config | 5 GiB | 0.15 GB | cold |
+| radarr-config | radarr | config db | 5 GiB | 0.15 GB | cold |
+| pihole-config | pihole | config | 2 GiB | 0.10 GB | cold |
+| jackett-config | jackett | config | 2 GiB | 0.10 GB | cold |
+| seerr/act-runner-data | gitea-actions | CI cache | 1 GiB | 0.05 GB | cold |
+| semaphore-config | semaphore | config | 1 GiB | 0.05 GB | cold |
+| **TOTALS (per node / one replica)** | | | **152 GiB** | **~26.2 GB** | |
+
+- **Per node working set: ~26.2 GB actual** vs **152 GiB provisioned** (× 3 replicas =
+  456 GiB nominal, but Longhorn/ZFS are thin — nominal is not what lands on disk).
+- **Whole-cluster working set: ~79 GB** across the three nodes.
+- **Bulk media is not on Longhorn.** The StorageClass survey (§1.3) shows Plex media
+  libraries and the *arr download shares use the `bulk` NFS class
+  (`nfs.csi.k8s.io`), not Longhorn. So the "bulk stays on HDD while small/hot moves to
+  SSD" framing mostly dissolves: **there is no large Longhorn volume.** The biggest is
+  `unifi-rootdisk` at 6.2 GB actual, and it is a cold KubeVirt root disk.
+
+### 1.2 Longhorn per-node disk (the current single HDD data disk)
+
+`kubectl -n longhorn-system get nodes.longhorn.io` (all three nodes identical):
+
+| Field | Value |
+|---|---|
+| Disk | `default-disk`, path `/var/lib/longhorn`, tags `[]`, `allowScheduling: true` |
+| `storageMaximum` | 124.9 GiB (the ext4 fs on the 128 GiB `virtio1` HDD disk) |
+| `storageAvailable` | 100.4 GiB free |
+| `storageScheduled` | **152.0 GiB** — over-scheduled vs the 124.9 GiB max |
+
+The 152 GiB *scheduled* > 124.9 GiB *max* is Longhorn honouring
+`storage-over-provisioning-percentage: 200`. Actual usage is only ~24.5 GiB
+(124.9 − 100.4), matching §1.1.
+
+### 1.3 StorageClasses in play
+
+`kubectl get storageclass`:
+
+| Class | Provisioner | Notes |
+|---|---|---|
+| `longhorn` | `driver.longhorn.io` | default class, 3 replicas, ext4 — **17 of 18 PVCs** |
+| `longhorn-vm` | `driver.longhorn.io` | 3 replicas, `migratable: true` — `unifi-rootdisk` only |
+| `longhorn-scratch` | `driver.longhorn.io` | 1 replica, best-effort locality (ephemeral) |
+| `longhorn-static` | `driver.longhorn.io` | static-provisioning class |
+| `bulk` | `nfs.csi.k8s.io` | NFS — bulk media (unresolved `REPLACE-ME` server/share) |
+
+### 1.4 Longhorn settings relevant to a migration / rebuild storm
+
+`kubectl -n longhorn-system get settings.longhorn.io …`:
+
+| Setting | Value | Relevance |
+|---|---|---|
+| `concurrent-replica-rebuild-per-node-limit` | **1** | already throttled — one rebuild at a time per node (set during etcd work) |
+| `storage-over-provisioning-percentage` | 200 | dangerous on a *small* SSD disk — must lower for the SSD disk sizing |
+| `storage-minimal-available-percentage` | 25 | Longhorn stops scheduling when a disk is <25 % free — a safety floor |
+| `replica-auto-balance` | best-effort | will help spread replicas after a new disk appears |
+| `default-replica-count` | 3 | — |
+
+Longhorn version: **v1.12.1**. **No backup target is configured**
+(`backuptargets.longhorn.io/default`: URL empty, `available: false`) — so any
+migration path that relies on Longhorn *backup → restore-to-new-SC* is **not
+available** until an S3/NFS backup target is set up. This constrains the migration
+mechanism (§4) to in-cluster options: CSI clone, per-volume `diskSelector` rebuild, or
+app-level redeploy.
+
+### 1.5 The SSD pool (`local-zfs` = `rpool/data`)
+
+Measured read-only on 2026-08-29 during the etcd-isolation work
+(`docs/plans/ssd-etcd-isolation.md` §1.1) and unchanged in substance since — the only
+addition was the three 16 GiB etcd disks on 2026-08-30, which are thin and hold ~83 MB
+of etcd data each (~250 MB total actual):
+
+| Property | Value |
+|---|---|
+| Pool | `rpool`, mirror of 2 × Micron 5100/52x0 960 GB **enterprise SATA SSD w/ PLP** |
+| Health | 97 % lifetime remaining, 0 reallocated sectors — excellent |
+| `zpool` size / free | 888 G / **~350 G free** (60 % capacity) |
+| ZFS `AVAIL` to a new dataset/zvol | **~323 GiB** |
+| Proxmox host root on it | `rpool/ROOT/pve-1` = 430 G |
+| Storage entry | `local-zfs`, content `images,rootdir`, `sparse 1` (thin) |
+| Already carries | 3 × 16 GiB etcd zvols (thin, ~250 MB actual) |
+
+> **Re-verify at execution time.** Before applying, re-run `zpool list rpool` and
+> `pvesm status` on the Proxmox host to confirm current free space (this figure is
+> dated 2026-08-29). The vault-gated ansible path (`proxmox_hosts` group) or a Proxmox
+> UI check both work.
+
+### 1.6 Is the HDD *failing* — data-loss urgency?
+
+The problem statement calls the Seagate HDD "slow/failing." **SMART was not
+re-collected in this investigation** (the Proxmox host query is vault-gated in the
+dev container). The etcd-isolation doc characterised `Storage` as 2 × WDC WUH721818
+18 TB (healthy) and `Storage2` as 2 × Seagate ST8000VN004 — the Longhorn `virtio1`
+disks are on `Storage` (the WD mirror), a ZFS **mirror**, so a single-disk SMART fault
+is not immediate data loss. **Action item for the executor:** collect
+`smartctl -a` for both `Storage`-pool members and `zpool status -x` before scheduling;
+if a member is degraded, that raises urgency and argues for moving the *hot* data off
+sooner. Treat "failing" as unconfirmed until SMART is read — but the mirror + 3-way
+Longhorn replication means the plan is not gated on it.
+
+---
+
+## 2. Capacity verdict — does it fit?
+
+| Scenario | Per-node SSD footprint (actual) | ×3 across nodes | Provisioned to size the disk | Fits in ~323 GiB SSD `AVAIL`? |
+|---|---:|---:|---:|---|
+| **Hot tier** (Prometheus + 3 CNPG DBs + Loki + gitea) | **~16.9 GB** | **~50.6 GB** | 38 GiB/node → suggest a **48 GiB** SSD disk/node | **Yes, comfortably** (~145 GiB of thin zvols max, ~51 GB actual) |
+| **Full move** (all 18 Longhorn volumes) | ~26.2 GB | ~79 GB | 152 GiB/node nominal, but thin | **Yes on space** (~79 GB actual) — the "doesn't fit" blocker was a *provisioned*-number artefact |
+| All-SSD mini-PC path (no move now) | — | — | — | N/A — hardware-blocked, no committed date |
+
+**The recorded blocker is overturned by the actual numbers.** 3 × 128 GiB = 384 GiB
+*provisioned* does not fit next to the 430 GiB host root on an 888 GiB pool — that is
+true and is why the earlier doc said "NO for Longhorn." But the **real data is ~79 GB**,
+and both ZFS (`sparse 1`) and Longhorn are thin, so what actually lands on the SSD is
+the working set, not the nominal disk size. Both a hot-tier move and a full move fit on
+free space today.
+
+The reason to still prefer the **hot tier** over a full move is **not space** — it is
+**I/O coupling** (see §3.4 and §6): the only SSD pool is `rpool`, which now also carries
+the Proxmox host root *and* the freshly-isolated etcd disks. A full move puts every
+Longhorn rebuild back onto the same pool as etcd, partially undoing the isolation just
+completed. A hot-tier move keeps the SSD footprint and the rebuild-I/O burst small while
+capturing the single largest and churniest contributor (Prometheus = 11.6 GB = 44 % of
+the whole working set) and all the latency-sensitive Postgres DBs.
+
+---
+
+## 3. Options evaluated
+
+### 3.1 Option A — Hot-tier move onto a tagged SSD Longhorn disk (RECOMMENDED)
+
+Add a second, SSD-backed Longhorn data disk per node (a new `virtio3` zvol on
+`local-zfs`), tag it `ssd`, tag the existing HDD disk `hdd`, publish a `longhorn-ssd`
+StorageClass with `diskSelector: ["ssd"]`, and migrate the hot volumes onto it. Cold
+config volumes stay on the HDD `default-disk`.
+
+- **Hot set:** `prometheus-…-db-0` (monitoring), `storage-loki-0` (monitoring),
+  `keycloak-db-1`, `nextcloud-db-1`, `semaphore-db-1` (the three CNPG Postgres DBs),
+  `gitea-data`. ~16.9 GB/node actual, 38 GiB provisioned.
+- **Why these:** Prometheus is the biggest and churniest (TSDB compaction + snapshot
+  bloat — 11.6 GB actual on an 8 GiB nominal volume). Postgres DBs are fsync-latency
+  sensitive and small. Loki and gitea are moderate-churn. Moving these removes the bulk
+  of rebuild bytes *and* the latency-sensitive I/O from the HDD.
+- **Footprint:** small and bounded → the I/O-coupling risk on `rpool` is minimal.
+- **Downside:** the ~12 cold config volumes (~9 GB/node) still rebuild on the HDD on a
+  reboot — but they are tiny and low-churn, so the storm shrinks from 18 volumes /
+  ~26 GB to ~12 volumes / ~9 GB, and the SSD ones rebuild fast.
+
+### 3.2 Option B — Full move (all 18 Longhorn volumes to SSD)
+
+Size the SSD disk per node for the full working set (e.g. 96 GiB thin, lower
+over-provisioning) and repoint the default StorageClass / migrate every volume.
+
+- **Pro:** eliminates HDD Longhorn rebuild entirely — reboots no longer touch the HDD
+  for storage; SSD rebuild is fast and low-IO-delay.
+- **Con:** re-couples *all* Longhorn rebuild I/O with etcd + host root on `rpool`,
+  partially undoing `docs/plans/ssd-etcd-isolation.md`. SSD IOPS make this far less
+  harmful than the HDD case, but it is a real regression of the isolation just done.
+  Also consumes more of the small SSD pool's headroom.
+- **Verdict:** feasible, but hold it as a *Phase 2* only if the hot-tier move proves
+  insufficient. Not the opening move.
+
+### 3.3 Option C — Do nothing; wait for the all-SSD mini-PCs
+
+Zero work, zero risk, but leaves the cluster fragile to every node bounce
+indefinitely — the mini-PC migration has no committed date. What that path *requires*:
+new hardware (all-SSD mini-PCs), a fresh Proxmox/k3s build, and a full Longhorn data
+migration anyway. Option A is a cheap, reversible bridge that the mini-PC path later
+supersedes — it does not waste that work (the `longhorn-ssd` class and tagging carry
+over).
+
+### 3.4 The I/O-coupling caveat (applies to A and B)
+
+`rpool` is the **only** SSD pool. It already carries the host root and the isolated
+etcd disks. Putting Longhorn rebuild I/O back on it re-introduces *some* contention
+with etcd's WAL fsync — the exact thing the etcd disk was meant to escape. Two facts
+keep Option A safe: (1) SSD random IOPS are ~2–3 orders of magnitude above the HDD, so
+concurrent fsync + rebuild is tolerable where it was fatal on spinning rust; (2) the
+hot-tier footprint is small so rebuild bursts are short. **Mitigation:** keep
+`concurrent-replica-rebuild-per-node-limit: 1`, and watch
+`etcd_disk_wal_fsync_duration_seconds` (Prometheus) during the first SSD rebuild — if
+p99 fsync climbs materially, stop and reassess before proceeding to the next node.
+
+---
+
+## 4. Recommended implementation — Option A, phased, one node at a time
+
+> Every step below is a *proposal*. Nothing here has been executed. Apply per node,
+> lowest-quorum-risk node first, verifying Longhorn/etcd health between nodes.
+
+### Phase 0 — Pre-flight (read-only, do before touching anything)
+
+1. Re-verify SSD free space: on the Proxmox host `zpool list rpool` and `pvesm status`
+   (confirm ≳ 100 GiB `AVAIL` remains after the etcd zvols).
+2. Collect HDD SMART: `smartctl -a` on both `Storage`-pool members + `zpool status -x`.
+   If a member is degraded, note the added urgency but the mirror + 3× replication mean
+   the plan is unchanged.
+3. Confirm Longhorn is fully healthy (all volumes `robustness: healthy`) and no rebuild
+   is in flight. Do not start during a rebuild.
+4. Snapshot the CNPG DBs (CNPG can take an on-demand base backup) and note that gitea /
+   Prometheus / Loki data is reproducible or non-critical — belt-and-braces before any
+   volume move, since there is no Longhorn backup target.
+
+### Phase 1 — Add an SSD Longhorn disk per node (tofu, mirrors the etcd-disk pattern)
+
+The VMs are bpg/OpenTofu-managed (`infra/tofu/main.tf`,
+`resource "proxmox_virtual_environment_vm" "node"`, `for_each = local.nodes`). Disks
+are `disk {}` blocks; `virtio0` (OS) and `virtio1` (Longhorn HDD) are on `var.datastore`
+(`Storage`), `virtio2` (etcd) is on `var.etcd_ssd_datastore` (`local-zfs`). Add a
+**fourth disk on the SSD datastore**, kept last so bpg does not reorder existing disks.
+
+1. New variables in `infra/tofu/variables.tf`:
+   ```hcl
+   variable "longhorn_ssd_datastore" {
+     description = "SSD-backed datastore for the tagged Longhorn SSD disk (local-zfs = rpool/data, Micron 5100 SATA SSD mirror w/ PLP)."
+     type        = string
+     default     = "local-zfs"
+   }
+   variable "longhorn_ssd_disk_gib" {
+     description = "Per-node SSD Longhorn disk, GiB. Hot tier is ~17 GiB actual / 38 GiB provisioned; 48 GiB gives headroom without crowding rpool."
+     type        = number
+     default     = 48
+   }
+   ```
+2. New `disk {}` block in the VM resource in `main.tf`, appended **after** the
+   `virtio2` etcd block (ascending interface → `virtio3` → `/dev/vdd`):
+   ```hcl
+   # Tagged SSD Longhorn disk (virtio3 -> /dev/vdd) for the hot tier (Prometheus, CNPG
+   # DBs, Loki, gitea). See docs/plans/longhorn-ssd-tiering.md. Kept last so bpg won't
+   # reorder virtio0/1/2. discard=on so ext4/Longhorn TRIM reclaims thin zvol space.
+   disk {
+     datastore_id = var.longhorn_ssd_datastore
+     interface    = "virtio3"
+     size         = var.longhorn_ssd_disk_gib
+     discard      = "on"
+     cache        = "none"
+     iothread     = false
+   }
+   ```
+3. `tofu plan` **must** show an in-place *disk add* (update) for each node — **not** a
+   replacement. If it shows replace, stop (never destroy a running etcd node).
+4. Apply **one node at a time** with `-target` on the name-keyed resource address,
+   e.g. `-target='proxmox_virtual_environment_vm.node["k3s-dev-3"]'`. A disk add is
+   applied online by bpg, but treat the node as maintenance-affected regardless.
+
+### Phase 2 — Format + mount the SSD disk (ansible `node_baseline`, mirrors etcd)
+
+`roles/node_baseline` already formats/mounts the HDD Longhorn disk (`/dev/vdb` →
+`/var/lib/longhorn`) and the etcd disk (`/dev/vdc`). Add the same idempotent,
+data-safe pattern for `/dev/vdd`:
+
+1. New defaults in `roles/node_baseline/defaults/main.yml`:
+   ```yaml
+   node_baseline_longhorn_ssd_device: /dev/vdd
+   node_baseline_longhorn_ssd_mount: /var/lib/longhorn-ssd
+   node_baseline_longhorn_ssd_fs_label: longhorn-ssd
+   ```
+2. New tasks in `roles/node_baseline/tasks/main.yml` (copy the HDD Longhorn
+   filesystem+mount pair; `community.general.filesystem` never reformats an existing
+   fs, so re-runs are safe):
+   ```yaml
+   - name: Create ext4 filesystem on the SSD Longhorn disk (data-safe; skips if present)
+     community.general.filesystem:
+       fstype: ext4
+       dev: "{{ node_baseline_longhorn_ssd_device }}"
+       opts: "-L {{ node_baseline_longhorn_ssd_fs_label }}"
+   - name: Mount the SSD Longhorn disk
+     ansible.posix.mount:
+       path: "{{ node_baseline_longhorn_ssd_mount }}"
+       src: "LABEL={{ node_baseline_longhorn_ssd_fs_label }}"
+       fstype: ext4
+       opts: "defaults,nofail,x-systemd.device-timeout=5s"
+       state: mounted
+   ```
+   Use `LABEL=` (not `/dev/vdd`) so the fstab entry survives device renames, and
+   `nofail` so a missing SSD Longhorn disk does not block boot (unlike etcd, an absent
+   Longhorn extra-disk should not wedge the node).
+
+### Phase 3 — Register + tag the disks in Longhorn
+
+Per node (via the Longhorn `nodes.longhorn.io` CR or UI):
+
+1. **Tag the existing HDD disk** `default-disk` with `hdd` and set the new
+   `longhorn-ssd` StorageClass's counterpart default class to select it (so cold
+   volumes stay put and nothing hot accidentally lands on HDD once the SSD class
+   exists).
+2. **Add the SSD disk** at `/var/lib/longhorn-ssd` as a new Longhorn disk on each node,
+   `allowScheduling: true`, tag `ssd`.
+   ```yaml
+   # patch each nodes.longhorn.io/<node> .spec.disks
+   disk-ssd:
+     path: /var/lib/longhorn-ssd
+     allowScheduling: true
+     tags: ["ssd"]
+     storageReserved: 0
+   ```
+3. Confirm each node now reports two disks with correct `storageMaximum` (~48 GiB for
+   the SSD one) and `Schedulable` condition true.
+
+### Phase 4 — Publish the `longhorn-ssd` StorageClass
+
+New GitOps manifest (wherever the Longhorn StorageClasses are declared in
+`platform/` — mirror the existing `longhorn` class and add the selector):
+
+```yaml
+apiVersion: storage.k8s.io/v1
+kind: StorageClass
+metadata:
+  name: longhorn-ssd
+provisioner: driver.longhorn.io
+allowVolumeExpansion: true
+parameters:
+  numberOfReplicas: "3"
+  staleReplicaTimeout: "30"
+  fsType: ext4
+  dataLocality: disabled
+  diskSelector: "ssd"          # only schedules replicas on ssd-tagged disks
+  disableRevisionCounter: "true"
+  unmapMarkSnapChainRemoved: "ignored"
+```
+
+Optionally add a matching `diskSelector: "hdd"` to the existing default `longhorn`
+class so newly-created cold volumes stay on HDD.
+
+### Phase 5 — Migrate the hot volumes (no Longhorn backup target → in-cluster methods)
+
+Because no backup target exists (§1.4), use one of these, **one volume at a time**,
+respecting `concurrent-replica-rebuild-per-node-limit: 1`:
+
+- **CNPG DBs (keycloak / nextcloud / semaphore) — cleanest via the operator.** Change
+  the CNPG `Cluster` `.spec.storage.storageClass` to `longhorn-ssd` and let CNPG do a
+  rolling replica re-creation (it provisions a fresh instance on the new class, streams
+  from the primary, then promotes) — no manual data copy, no downtime beyond a
+  switchover. Do one CNPG cluster at a time; verify replication caught up before the
+  next.
+- **Prometheus / Loki / gitea — per-volume `diskSelector` rebuild (in place, no PVC
+  swap).** Patch the existing Longhorn volume to select the SSD disk and let Longhorn
+  rebuild the replicas onto it, then drop the HDD replicas:
+  ```
+  kubectl -n longhorn-system patch volumes.longhorn.io <vol> --type merge \
+    -p '{"spec":{"diskSelector":["ssd"]}}'
+  ```
+  Then trigger a controlled rebuild by deleting **one** HDD replica at a time (Longhorn
+  reschedules onto an `ssd`-tagged disk; `replica-auto-balance: best-effort` helps).
+  Watch the volume return to `robustness: healthy` before touching the next replica or
+  the next volume. This avoids recreating PVCs and keeps the app running.
+  - Alternative if the in-place rebuild misbehaves: scale the app to 0, CSI-**clone**
+    the PVC onto `longhorn-ssd` (`dataSource` = existing PVC), repoint the workload to
+    the clone, scale back up. More disruptive; keep as fallback.
+
+### Phase 6 — Validate
+
+1. All hot volumes `robustness: healthy`, replicas only on `ssd`-tagged disks
+   (`kubectl -n longhorn-system get replicas.longhorn.io -o wide`).
+2. SSD Longhorn disk usage ≈ 17 GiB/node; HDD disk down to the cold ~9 GiB/node.
+3. Deliberately reboot **one** node and confirm the rebuild storm is materially smaller
+   (fewer volumes, SSD-fast) and Proxmox IO-delay stays low. Confirm etcd fsync p99 did
+   not regress during the SSD rebuild (§3.4).
+
+---
+
+## 5. Rebuild-storm mitigation (built into the plan)
+
+- **One node at a time** for every phase (tofu `-target`, ansible `--limit`, one CNPG
+  cluster / one replica at a time) — etcd quorum is 3-node, never take two down.
+- **`concurrent-replica-rebuild-per-node-limit: 1`** already set — a rebooted node
+  rebuilds serially, capping IO-delay.
+- **Migrate during a quiet window**, never while another rebuild is in flight.
+- **Lower `storage-over-provisioning-percentage`** *for the small SSD disk sizing* —
+  200 % on a 48 GiB disk would let Longhorn schedule ~96 GiB of nominal claims onto
+  ~17 GiB of real data; keep the hot set well under `storageMaximum`, and rely on
+  `storage-minimal-available-percentage: 25` as the floor. (The setting is global —
+  consider dropping it to ~120–150 % cluster-wide, or simply keep the SSD disk sized so
+  200 % of the hot claims still fits.)
+- **Verify etcd fsync latency** during the first SSD rebuild before proceeding (§3.4).
+
+---
+
+## 6. Risks and rollback
+
+| Risk | Likelihood | Mitigation / rollback |
+|---|---|---|
+| SSD rebuild I/O re-starves etcd on shared `rpool` | Low (SSD IOPS) | rebuild-limit 1; watch `etcd_disk_wal_fsync_duration`; stop after node 1 if p99 regresses |
+| SSD pool fills (host root 430 G + etcd + Longhorn on 888 G) | Low (hot set ~51 GB) | keep SSD disk small (48 GiB), `storage-minimal-available-percentage: 25`; re-check `zpool list` between nodes |
+| tofu shows *replace* instead of disk-add | Medium if module drift | inspect `tofu plan` per node; abort on replace — never destroy a running etcd node |
+| Volume-migration data loss (no backup target) | Low | CNPG native rolling; per-volume rebuild keeps HDD replica until SSD healthy; CNPG base backup + reproducible data taken in Phase 0 |
+| Data disk device rename (`/dev/vdd` shifts) | Low | mount by `LABEL=longhorn-ssd`, not device path |
+| HDD actually failing mid-migration | Unknown (SMART unread) | 3× replication + mirror; Phase 0 SMART check; hot data lands on SSD first, reducing exposure |
+
+**Rollback:** every phase is reversible. To back out: migrate the hot volumes back to
+the HDD `default-disk` (reverse the `diskSelector` patch / point CNPG back at
+`longhorn`), remove the `disk-ssd` from each Longhorn node, delete the `longhorn-ssd`
+StorageClass, then remove the `virtio3` disk block from tofu and re-apply one node at a
+time. The SSD zvols are thin and independent of the HDD data, so removal is clean.
+
+---
+
+## 7. Recommendation
+
+**Adopt Option A (hot-tier move), phased, one node at a time.** The recorded "SSD
+doesn't fit Longhorn" blocker was based on the 384 GiB *provisioned* figure; the
+**actual working set is ~79 GB cluster-wide (~26 GB/node)** because all bulk media
+lives on NFS and every Longhorn volume is a small config/DB volume. The hot tier
+(Prometheus + the three CNPG Postgres DBs + Loki + gitea) is **~51 GB actual /
+114 GiB provisioned** across three nodes and fits the ~323 GiB SSD `AVAIL` with wide
+headroom, while capturing the single largest and churniest rebuild contributor
+(Prometheus, 44 % of the working set) and the latency-sensitive databases.
+
+A **full move is feasible on space** and would fully eliminate HDD Longhorn rebuilds,
+but it re-couples all rebuild I/O with etcd + host root on the only SSD pool, partially
+undoing the just-completed etcd isolation — hold it as an optional Phase 2 gated on the
+hot-tier move proving insufficient. **Option C (wait for mini-PCs) is not a solution**
+tonight — no committed date, and the tagging + `longhorn-ssd` class built here carry
+over to that migration anyway.
+
+**Do this first, before any apply:** re-verify live SSD free space (`zpool list
+rpool`, `pvesm status`) and read HDD SMART (`smartctl -a`, `zpool status -x`). If the
+Seagate/`Storage` pool shows a degraded member, the urgency rises and the hot-tier move
+should be scheduled sooner — but the mirror + 3× Longhorn replication mean the plan is
+not gated on the disk's health.

+# Phase 2 execution runbook — SSD-backed etcd migration (interactive/manual)
+
+> ## ✅ COMPLETED / historical — executed 2026-08-30, see git log
+>
+> **This runbook has been executed.** Every k3s node's etcd now lives on its dedicated SSD `virtio2`
+> disk. The command sequence below is retained as the record of how the migration was performed — do
+> NOT re-run it against the live cluster. Current state is tracked in `infra/PHASE1-STATUS.md` and the

+
+Companion to `ssd-etcd-isolation.md`. This is the **exact command sequence** to migrate
+each k3s node's etcd onto its dedicated SSD `virtio2` disk. It must be run where live-infra
+mutations are permitted — an **interactive `claude` session** (default permission mode, which
+prompts for approval) or **by hand**. The autonomous "auto mode" session hard-denies
+`tofu apply` and node-level ssh mutations, so it cannot run this.
+
+## Preconditions (verified 2026-08-29, cluster healthy)
+- Run everything from the staged worktree that carries the tofu disk block:
+  `cd /home/jakman85/source/home-network-k3s-impl/.claude/worktrees/agent-ssd-etcd`
+  (branch `feature/ssd-etcd-isolation` @ `af5fc5b`).
+- All tooling via the devcontainer: `./infra/devcontainer/dev.sh run <cmd>`.
+- `./infra/devcontainer/dev.sh run ./infra/tofu/tf.sh init` once (done).
+- Ansible must run from `infra/ansible/` (for the vault-pass path): wrap as
+  `./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible ...'`.
+- **Run mutation commands STANDALONE** (not chained with `&&`/pipes) — the classifier is
+  more likely to deny a compound command that embeds a mutation.
+
+## ORDER (leader last — RE-VERIFY before each node)
+Current leader = **dev-3**, so: **dev-2 (vmid 102) → dev-1 (vmid 105) → dev-3 (vmid 101)**.
+dev-3 is last and additionally gets the memory 16384→24576 bump (needs a full stop/start).
+Re-check the leader before each node and keep the leader last:
+```
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s_servers -m shell -a "curl -s http://127.0.0.1:2381/metrics | grep etcd_server_is_leader"'
+```
+
+## Pre-flight before EACH node (read-only — all must pass)
+```
+./infra/devcontainer/dev.sh run kubectl get nodes
+./infra/devcontainer/dev.sh run kubectl get --raw=/readyz/etcd            # expect: ok
+./infra/devcontainer/dev.sh run kubectl -n longhorn-system get volumes.longhorn.io -o custom-columns=R:.status.robustness --no-headers | grep -c healthy   # expect: 18
+```
+
+## Per-node procedure (substitute NODE=k3s-dev-N, VMID)
+
+### 1. Freeze rebuilds (STANDALONE)
+```
+./infra/devcontainer/dev.sh run kubectl -n longhorn-system patch settings.longhorn.io concurrent-replica-rebuild-per-node-limit --type=merge -p '{"value":"0"}'
+```
+
+### 2. Add the SSD disk via tofu (STANDALONE). dev-2/dev-1 = disk only; dev-3 also memory.
+```
+./infra/devcontainer/dev.sh run ./infra/tofu/tf.sh plan  '-target=proxmox_virtual_environment_vm.node["k3s-dev-N"]'   # confirm: disk ADD, in-place, NOT replace
+./infra/devcontainer/dev.sh run ./infra/tofu/tf.sh apply -auto-approve '-target=proxmox_virtual_environment_vm.node["k3s-dev-N"]'
+```
+Confirm the guest sees the new disk (hot-plug):
+```
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -m shell -a "lsblk /dev/vdc"'
+```
+If `/dev/vdc` is NOT present (no hot-plug), power-cycle the VM (freeze is holding):
+```
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible proxmox -m shell -a "qm stop VMID"'   # wait until stopped
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible proxmox -m shell -a "qm start VMID"'
+```
+(For dev-3 the memory bump requires this stop/start regardless.)
+
+### 3. Migrate etcd data (node commands, become=root). Do NOT skip the copy-before-mount order.
+```
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -b -m shell -a "systemctl stop k3s"'
+# mkfs ONLY if /dev/vdc has no filesystem yet (fresh disk):
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -b -m shell -a "blkid /dev/vdc || mkfs.ext4 -L k3s-etcd /dev/vdc"'
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -b -m shell -a "mv /var/lib/rancher/k3s/server/db /var/lib/rancher/k3s/server/db.bak && mkdir /var/lib/rancher/k3s/server/db && mount LABEL=k3s-etcd /var/lib/rancher/k3s/server/db && rsync -aHAX --numeric-ids /var/lib/rancher/k3s/server/db.bak/ /var/lib/rancher/k3s/server/db/"'
+# Persist the mount (matches the node_baseline role: LABEL + defaults,noatime):
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -b -m ansible.posix.mount -a "path=/var/lib/rancher/k3s/server/db src=LABEL=k3s-etcd fstype=ext4 opts=defaults,noatime dump=0 passno=2 state=mounted"'
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -b -m shell -a "systemctl start k3s"'
+```
+
+### 4. VERIFY full recovery before touching the next node (all must pass)
+```
+./infra/devcontainer/dev.sh run kubectl get nodes                          # NODE Ready
+./infra/devcontainer/dev.sh run kubectl get --raw=/readyz/etcd             # ok
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -m shell -a "findmnt /var/lib/rancher/k3s/server/db"'   # source = /dev/vdc
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s_servers -m shell -a "curl -s http://127.0.0.1:2381/metrics | grep etcd_server_has_leader"'  # all =1
+./infra/devcontainer/dev.sh run kubectl -n longhorn-system get volumes.longhorn.io -o custom-columns=R:.status.robustness --no-headers | grep -c healthy   # 18
+# dev-3 only: confirm ~24Gi allocatable
+./infra/devcontainer/dev.sh run kubectl get node k3s-dev-3 -o jsonpath='{.status.allocatable.memory}'
+```
+
+### 5. Thaw + clean up (STANDALONE), only after step 4 fully passes
+```
+./infra/devcontainer/dev.sh run kubectl -n longhorn-system patch settings.longhorn.io concurrent-replica-rebuild-per-node-limit --type=merge -p '{"value":"1"}'
+./infra/devcontainer/dev.sh run bash -lc 'cd infra/ansible && ansible k3s-dev-N -b -m shell -a "rm -rf /var/lib/rancher/k3s/server/db.bak"'
+```
+Wait for 18/18 healthy (no rebuild storm), re-verify leader, then proceed to the next node.
+
+## STOP conditions (halt immediately, leave limit=0, do not advance)
+etcd `/readyz` not ok, a member without a leader, VIP `192.168.2.50:6443` flapping, a node
+not rejoining, any Longhorn volume Faulting, or k3s crashlooping. Recovery: keep rebuilds
+frozen; a botched single member can be reset and re-joined from the other two (plan §4.5).
+
+## Close-out (after all 3)
+- All 3 nodes Ready; etcd 3/3 with a leader; `findmnt` shows `/dev/vdc` at the db path on each.
+- 18/18 Longhorn volumes healthy; rebuild-limit back to **1**.
+- `./infra/devcontainer/dev.sh run ./infra/tofu/tf.sh plan` → **No changes** (all disks present, dev-3 memory reconciled).
+- Merge `feature/ssd-etcd-isolation` → `main` and push (push is classifier-blocked in auto mode — run `git push gitea main` by hand) so Flux/tofu source records the disk + baseline.
+- Regression test: after approval, bounce ONE node and confirm etcd stays healthy / VIP steady — the whole point of the change.

+# SSD-backed etcd isolation for the k3s dev cluster
+
+> ## ✅ COMPLETED / historical — executed 2026-08-30, see git log
+>
+> **This proposal was approved and carried out.** Each node now has a dedicated `virtio2` SSD etcd
+> disk (`/dev/vdc`, `local-zfs`) hosting the etcd data dir. The **Status: PROPOSAL** line below and
+> the sizing/RAM figures are the original investigation record — retained for the reasoning, not as a
+> live to-do. Current state is tracked in `infra/PHASE1-STATUS.md` and the 2026-08-30 DECISIONS-LOG entry.
+
+**Status:** PROPOSAL — awaiting user approval. No changes have been made.
+**Author:** investigation agent (read-only), 2026-08-29
+**Problem:** Longhorn replica-rebuild I/O storms on the HDD-backed VM disks starve
+etcd's WAL fsync, crash-looping k3s and flapping the kube-vip VIP
+(`192.168.2.50:6443`). Even `concurrent-replica-rebuild-per-node-limit=1` tips etcd.
+**Question:** Can the Proxmox host's ~1 TB system SSD (`rpool`) host dedicated
+SSD-backed storage for etcd (and/or Longhorn) to end these incidents?
+
+**Verdict: YES for etcd (strongly recommended). NO for Longhorn.**
+
+---
+
+## 1. Measured facts (all collected read-only on 2026-08-29)
+
+### 1.1 `rpool` — the system/boot SSD pool
+
+| Property | Value |
+|---|---|
+| Pool | `rpool`, **mirror** (`mirror-0`) of 2 devices |
+| Devices | `ata-MTFDDAK960TDS_...` × 2 — **Micron 5100/52x0 960 GB, 2.5" SATA** |
+| Class | **Enterprise SATA SSD with power-loss protection (PLP)** — safe for sync/fsync |
+| Health | `Percent_Lifetime_Remain` = **97%** (3% used), 13 904 power-on hours, 0 reallocated sectors, ~96 TB written. Excellent. |
+| Pool size / alloc / **free** | 888 G / 538 G / **350 G free** (`zpool list`, 60% cap) |
+| ZFS `AVAIL` | **~323 GiB** available to any new dataset/zvol |
+| System root | `rpool/ROOT/pve-1` = **430 G used** (Proxmox host `/`) |
+| Proxmox storage on it | `local-zfs` → pool `rpool/data`, `content images,rootdir`, **`sparse 1`** (thin), ~338 GiB available per `pvesm status` |
+| Pool settings | `compression on`, **`sync standard`** (inherited), `dedup off`, recordsize 128K |
+
+`local-zfs` already advertises `images,rootdir` content, so **Proxmox can place VM
+disks on the SSD today with no storage-config change.**
+
+### 1.2 Current VM disk backing — confirms the HDD assumption
+
+VMs (bpg/OpenTofu-provisioned): **dev-1 = vmid 105, dev-2 = 102, dev-3 = 101**.
+Each has two disks, **both on the `Storage` datastore**:
+
+- `Storage` = ZFS pool on **2× WDC WUH721818ALE6L4 18 TB HDD** (`sdc`/`sdd`, `ROTA=1`), mirror, 16.4 T.
+- Per node: `virtio0 = vm-<id>-disk-0` (64 G, OS/root) and `virtio1 = vm-<id>-disk-1` (128 G, Longhorn data). `volblocksize 16K`.
+
+So **etcd, the OS, and Longhorn all currently sit on spinning rust.** That is the
+root cause: etcd WAL fsync competes with Longhorn rebuild I/O on the same HDD spindles.
+
+(`Storage2` = 2× Seagate ST8000VN004 8 TB HDD is a separate HDD pool, not involved.)
+
+### 1.3 Size of the hot data
+
+- **etcd DB: ~82.6 MB.** Measured via apiserver metric
+  `apiserver_storage_size_bytes{storage_cluster_id="etcd-0"} = 8.264e7`.
+  A 4-day-old cluster running ~18 services. Even allowing generous WAL + growth
+  headroom, **etcd fits in single-digit GB with room to spare — trivially ×3.**
+- **Longhorn: ~22 GB actual data per node right now**, but the data disk is
+  **128 GiB** and Longhorn reports `storageScheduled ≈ 152 GiB` (thin-overcommitted)
+  vs `storageMaximum ≈ 125 GiB` per node. 18 PVCs, `numberOfReplicas=3`.
+  Provisioned total ≈ 152 GiB. Longhorn is the **churn source we want to isolate
+  etcd from**, and it can grow toward 128 GiB/node.
+
+### 1.4 Sizing conclusion
+
+| Candidate | Per-node footprint | ×3 on rpool | Fits in 323 GiB avail? |
+|---|---|---|---|
+| **etcd** | ~83 MB now; size a 16 GiB disk | ~48 GiB reserved (thin) | **Yes, easily** |
+| **Longhorn** | ~22 GB now, up to 128 GiB provisioned | up to **~384 GiB** | **No — would fill/threaten the boot disk** |
+
+---
+
+## 2. Viability verdict
+
+**etcd on SSD: viable and high-leverage.** etcd is ~83 MB; three 16 GiB SSD-backed
+disks cost ~48 GiB of thin allocation (actual ~250 MB) against 323 GiB free on an
+enterprise, PLP-equipped, 97%-healthy SSD mirror. This directly removes the WAL
+fsync path from the HDD contention domain — the smallest-footprint fix for the exact
+failure mode. **This is the recommendation.**
+
+**Longhorn on SSD: not viable here.** Its provisioned footprint (~384 GiB across 3
+replicas at full size) does not fit alongside the 430 GiB Proxmox root on a 888 GiB
+pool, and co-locating heavy Longhorn rebuild I/O on the boot SSD reintroduces
+contention with the host itself. Keep Longhorn on HDD (`Storage`). Rejected.
+
+---
+
+## 3. Options evaluated
+
+- **Option A — dedicated small SSD disk per node, etcd-only (RECOMMENDED).**
+  Add a ~16 GiB SSD-backed virtual disk (zvol on `rpool/data` via `local-zfs`) to
+  each of the 3 VMs, mount it at the k3s etcd directory
+  (`/var/lib/rancher/k3s/server/db`), migrate etcd data onto it one node at a time.
+  Isolates WAL fsync from HDD Longhorn churn. Minimal space, minimal blast radius.
+- **Option B — Longhorn replicas/disk on SSD.** Rejected (§2): does not fit and
+  re-couples host I/O.
+- **Option C — do nothing; wait for the SSD mini-PCs.** Zero risk, zero work, but
+  leaves the cluster fragile to every node bounce until the mini-PC migration lands
+  (deferred, no committed date). Option A is a cheap, reversible bridge that Option C
+  eventually supersedes (§7).
+
+**Recommendation: Option A now, as an interim fix, carried by tofu.**
+
+---
+
+## 4. Recommended implementation — Option A, step-by-step
+
+### 4.1 Model it in tofu (preferred over manual)
+
+The VMs are bpg/OpenTofu-managed (`infra/tofu/`). Disks are declared as `disk`
+blocks in `main.tf`; both current disks (`virtio0`, `virtio1`) point at
+`var.datastore` (`Storage`). Add a **third disk on the SSD datastore**:
+
+1. **New variables** in `infra/tofu/variables.tf`:
+   ```hcl
+   variable "etcd_ssd_datastore" {
+     description = "SSD-backed datastore for the dedicated etcd disk (VERIFIED: local-zfs = rpool/data, ZFS mirror on Micron 5100 SATA SSDs w/ PLP)."
+     type        = string
+     default     = "local-zfs"
+   }
+   variable "etcd_disk_gib" {
+     description = "Dedicated SSD etcd disk per node, GiB (etcd DB is ~83 MB; 16 GiB is generous headroom)."
+     type        = number
+     default     = 16
+   }
+   ```
+2. **New disk block** in the VM resource in `main.tf`, appended AFTER the existing
+   `virtio1` block (keep interface order ascending so bpg does not reorder):
+   ```hcl
+   # Dedicated SSD etcd disk (virtio2 -> /dev/vdc). Isolates etcd WAL fsync from
+   # the HDD Storage pool where the OS + Longhorn disks live.
+   disk {
+     datastore_id = var.etcd_ssd_datastore
+     interface    = "virtio2"
+     size         = var.etcd_disk_gib
+     discard      = "on"
+     cache        = "none"   # honor guest fsync through to ZFS ZIL (PLP SSD = safe+fast)
+     iothread     = false
+   }
+   ```
+3. **Plan and inspect before applying.** `tofu plan` MUST show an **in-place update
+   (disk add)** for the targeted VM — NOT a replacement. If it shows replace, stop and
+   reassess (do not destroy a running etcd node).
+4. **Apply one node at a time** with `-target` (see §4.3 for quorum ordering), e.g.
+   `-target='proxmox_virtual_environment_vm.node["k3s-dev-3"]'` (adjust to the actual
+   resource address in this repo). A disk add is applied online by bpg, but treat the
+   node as going down for the etcd migration regardless.
+
+> **Coupling caveat — dev-3 memory drift.** dev-1/dev-2 are at `memory_mib = 24576`
+> but **dev-3 is live at 16384** (drift from tofu default 24576). A tofu apply that
+> touches dev-3 will also try to reset its memory to 24576. Per the Proxmox rule,
+> memory changes need a **full stop/start**, not a reboot. Decide deliberately:
+> either (a) let the same maintenance window fix the memory drift on dev-3 (stop →
+> set → start), or (b) `-target` narrowly and accept that dev-3's plan will include
+> the memory change. Do dev-3 in its own window with eyes on it.
+
+**Manual alternative (if not using tofu):** on the Proxmox host,
+`qm set <vmid> -virtio2 local-zfs:16,discard=on,cache=none` then stop/start the VM.
+This drifts from tofu state and is discouraged — if done, import/reconcile into tofu
+afterward. Prefer the tofu path.
+
+### 4.2 Optional space guarantee
+
+`local-zfs` is `sparse` (thin), so the etcd zvols consume only real usage. To
+guarantee etcd can never be squeezed if the system disk fills, set a modest
+`refreservation` on each etcd zvol (e.g. `zfs set refreservation=16G
+rpool/data/vm-<id>-disk-2`). 3×16 GiB = 48 GiB reserved out of 323 GiB avail — safe.
+This is a host-side ZFS tweak, not expressible in bpg; apply manually if desired.
+
+### 4.3 Migrate etcd onto the new disk — quorum-safe, ONE node at a time
+
+k3s has no flag to relocate only the etcd directory (`--data-dir` moves everything),
+so the clean approach is to **mount the SSD disk at
+`/var/lib/rancher/k3s/server/db`** (this directory holds `etcd/` — member data, WAL,
+snapshots — and nothing else that matters).
+
+**Pre-flight:** confirm all 3 etcd members healthy and the cluster is quiet (no active
+Longhorn rebuild). `kubectl get nodes` all Ready; check etcd member health.
+
+**Per node, repeat for dev-3, then dev-2, then dev-1 (leader last):**
+
+1. Verify 3/3 etcd members healthy BEFORE touching this node (losing one of three
+   keeps quorum at 2/3; never take a second node until the previous is fully back).
+2. Stop k3s on the node: `systemctl stop k3s`. (Node leaves quorum; 2/3 remain.)
+3. Identify the new disk (`/dev/vdc` — the third virtio disk) and format it:
+   `mkfs.ext4 -L k3s-etcd /dev/vdc` (ext4 or xfs; ext4 is fine and simple).
+4. Preserve and move existing data:
+   ```
+   mv /var/lib/rancher/k3s/server/db /var/lib/rancher/k3s/server/db.bak
+   mkdir /var/lib/rancher/k3s/server/db
+   mount /dev/vdc /var/lib/rancher/k3s/server/db
+   rsync -aHAX --numeric-ids /var/lib/rancher/k3s/server/db.bak/ /var/lib/rancher/k3s/server/db/
+   ```
+5. Persist the mount in `/etc/fstab` **by UUID** (`blkid /dev/vdc`), e.g.
+   `UUID=<uuid> /var/lib/rancher/k3s/server/db ext4 defaults,noatime 0 2`, then
+   `systemctl daemon-reload`.
+6. Start k3s: `systemctl start k3s`. Wait until the node is `Ready` AND its etcd
+   member is healthy and has re-joined (member list shows 3 started, no learner
+   stuck). Confirm the VIP `192.168.2.50:6443` is stable.
+7. Only after full recovery, remove the backup: `rm -rf
+   /var/lib/rancher/k3s/server/db.bak`. Then proceed to the next node.
+
+**Reproducibility for rebuilds:** the SSD disk + mount should also be baked into the
+node **cloud-init first-boot baseline** (the same template that already provisions the
+Longhorn `virtio1` disk and swap-off), so a `tofu`-rebuilt node comes up with
+`/dev/vdc` formatted and mounted at the etcd path automatically. Update that template
+in the same change set as the tofu disk block.
+
+### 4.4 Validation
+
+- `kubectl get nodes` — all 3 Ready; no flapping over a 30–60 min soak.
+- etcd: 3 members, all started/healthy, one leader; DB size sane (~tens–hundreds MB).
+- On each node, `df -h /var/lib/rancher/k3s/server/db` shows the new `/dev/vdc` mount.
+- **Regression test the original failure:** with the cluster healthy, trigger a
+  controlled Longhorn replica rebuild (e.g. bounce ONE node after approval) and
+  confirm etcd stays healthy and the VIP does not flap — the whole point of the change.
+- Host-side: `zpool status rpool` clean; `zfs list rpool/data` shows the 3 new
+  `vm-*-disk-2` zvols with small real usage.
+
+### 4.5 Rollback
+
+Per node, fully reversible while `db.bak` still exists (before step 7):
+`systemctl stop k3s` → `umount .../server/db` → `rmdir` the empty mountpoint →
+`mv db.bak db` → remove the fstab line → `systemctl start k3s`. To fully revert the
+disk, detach `virtio2` (`qm set <vmid> -delete virtio2` after stop) or `tofu` revert
+the disk block, then stop/start. Because etcd is a replicated 3-member cluster, a
+botched single node can also simply be reset and re-joined from the other two.
+
+---
+
+## 5. Risks
+
+1. **System-disk contention / exhaustion (top risk).** `rpool` is also the Proxmox
+   boot/root disk (430 GiB used of 888 GiB). Mitigations: keep the etcd disks tiny
+   (16 GiB, thin), optional `refreservation` (§4.2), and **never** put Longhorn here
+   (§2). etcd's steady-state real usage is ~hundreds of MB; the marginal I/O it adds
+   to the SSD is negligible next to what it removes from the HDD.
+2. **Consumer-SSD fsync/PLP caveat — N/A here, but assert it.** etcd correctness under
+   power loss depends on honest fsync. These are **Micron 5100/52x0 enterprise SATA
+   SSDs with power-loss protection**, so `sync=standard` + `cache=none` is both fast
+   and durable. (If the disks were consumer SSDs without PLP this concern would be
+   real — it is not, for this hardware.)
+3. **Quorum during migration.** Mitigated by strict one-node-at-a-time with full
+   recovery gates (§4.3) and leader-last ordering. Never take a second node down
+   before the previous rejoins.
+4. **tofu coupling with dev-3 memory drift + apply semantics (§4.1).** An apply
+   touching dev-3 also resets memory 16384→24576 (needs stop/start). Verify `tofu
+   plan` shows disk *add*, not VM *replace*, before applying. Use `-target`.
+5. **Backup/restore assumptions.** k3s etcd snapshots (`/var/lib/rancher/k3s/server/db/snapshots`)
+   now live on the SSD too — fine, but confirm any snapshot/backup job still points at
+   the (unchanged) path.
+
+---
+
+## 6. Recommendation summary
+
+Implement **Option A**: a 16 GiB SSD-backed `virtio2` disk per k3s VM (zvol on
+`rpool/data` via `local-zfs`), etcd-only, migrated one node at a time with the
+quorum-safe procedure in §4.3, modeled in tofu (+ cloud-init baseline) for
+reproducibility. Do **not** move Longhorn to SSD. This is a small, reversible,
+high-leverage fix targeting the exact WAL-starvation failure.
+
+---
+
+## 7. Relationship to the deferred SSD-mini-PC migration
+
+This is explicitly an **interim bridge** on the current Proxmox dev host
+(`192.168.2.102`), whose bulk storage is HDD. Once the k3s cluster migrates to the
+planned **all-SSD mini-PCs**, every I/O path (OS, etcd, Longhorn) is already on SSD
+and the HDD-contention failure mode disappears — the dedicated etcd disk becomes
+unnecessary. At that point the isolation can be either dropped or carried forward
+harmlessly (a dedicated etcd disk is still good hygiene). Because Option A is captured
+in tofu + cloud-init, it travels with the cluster definition and can be removed in one
+reviewed change when the mini-PCs land. Until then it stops the recurring incidents
+at minimal cost.

+The dev path (OpenTofu → Proxmox VM → cloud-init) **does not apply**: there is no hypervisor API to

+Dev nodes for comparison: 8 vCPU / 24 GiB / Debian 13, **two** dedicated data disks (Longhorn + etcd).
+
+---
+
+## 1. Firmware / BIOS (per node, before OS install)
+
+- [ ] **Virtualization enabled** — VT-x *and* VT-d. Required for KubeVirt (R-PLAT-03); verify after
+      boot with `/dev/kvm` present and `grep -cE 'vmx|svm' /proc/cpuinfo` non-zero.
+- [ ] **AC power recovery = Power On.** A homelab node must return after a power cut without a
+      human pressing the button. (`docs/02` calls out wake/boot behaviour explicitly.)
+- [ ] **Wake-on-LAN enabled** on the onboard NIC (remote recovery when the box is off).
+- [ ] **Boot order** — internal disk first; USB above it only while imaging. Disable network boot
+      unless PXE is adopted.
+- [ ] **Secure Boot** — record the setting. k3s itself is fine either way; note it so all three
+      nodes match.
+- [ ] **Firmware version recorded** in §0 and consistent across all three nodes.
+
+## 2. Disk layout — **OPEN DECISION, blocks the build**
+
+`docs/02` requires the OS-vs-Longhorn device split to be **documented before prod build**. Dev went
+further and added a *third* device for etcd after HDD contention starved etcd WAL fsync
+(`docs/plans/ssd-etcd-isolation.md`).
+
+Node 1 as-found is a **single** 477 GB SATA SSD carrying everything:
+
+```
+sda  477G  C400-MTFDDAC512M (SSD, ~2011-era Micron/Crucial)
+├─sda1 976M  /boot/efi
+├─sda2  30G  /
+├─sda3  12G  /var
+├─sda4 977M  swap
+└─sda5 433G  /srv          <- the only large free space
+```
+
+Consequences to settle before imaging nodes 2 and 3:
+
+- [x] **Drive health MEASURED 2026-09-01** (`smartctl -a /dev/sda`, via the baseline package
+      floor — see §5). Raw attributes, so the numbers are auditable:
+
+      | | |
+      |---|---|
+      | Model | Crucial/Micron RealSSD m4/C400/P400 (`C400-MTFDDAC512MAM`, fw `070H`) |
+      | SMART self-assessment | **PASSED** — no attribute in `WHEN_FAILED` |
+      | Power-on hours | 6,814 (~284 days) · 147 power cycles |
+      | **Rated life used** | **31%** (`202`), i.e. 69% remaining (`173` VALUE 069) |
+      | **Grown failing blocks** | **15** (`170`), reallocation events **15** (`196`) |
+      | **Erase failures** | **187** (`172`) |
+      | **Unexpected power losses** | **32** (`174`) |
+      | Pending / offline-uncorrectable / reported-uncorrectable | **0 / 0 / 0** (`197`/`198`/`187`) |
+      | UDMA CRC errors | 0 (`199`) — cabling is clean |
+
+      **Read attribute `5` carefully.** Its raw value is `61440`, which is NOT a bad-sector
+      count: `61440 = 15 x 4096`, and both `170` and `196` independently read **15**. Its
+      normalised VALUE is 100 against a THRESH of 10. So the drive has **15 grown bad blocks**,
+      not sixty-one thousand bad sectors. The first `node_health` run FAILED on that raw value;
+      the check now judges on normalised VALUE/THRESH, `WHEN_FAILED`, and the vendor-independent
+      uncorrectable counters instead.
+
+      **Verdict: usable, but not for production state.** Nothing says imminent failure — no
+      pending or uncorrectable sectors, SMART self-assessment passes. But this is a ~2011
+      consumer MLC drive that has already consumed **31% of its rated life**, grown **15** bad
+      blocks, logged **187** erase failures, and taken **32** unclean power losses **with no
+      power-loss protection**, in a single failure domain. etcd is the worst possible tenant for
+      it: etcd fsyncs constantly, and an unclean power loss on a drive without PLP is exactly how
+      a member corrupts — this drive has already logged 32 of them.
+      (Non-ECC RAM is a separate, **accepted** risk — operator decision 2026-09-01, see
+      `DECISIONS-LOG.md`. It is not part of this verdict.)
+- [ ] **Decide the layout.**- [ ] **Decide the layout.** `roles/node_baseline` expects *block devices*
+      (`node_baseline_longhorn_device`, `node_baseline_etcd_device`) and makes a filesystem on them.
+      Its defaults `/dev/vdb` and `/dev/vdc` are **virtio names that do not exist on bare metal** —
+      prod must override them in `group_vars`. On a single-disk node there is no second device at
+      all, so one of:
+      - **Add a second drive** (M.2 NVMe if the chassis has a free slot; verify physically — only a
+        SATA controller is populated today). Cleanest: matches dev's isolation, gives etcd its own
+        spindle.
+      - **Use `/dev/sda5`** (the 433 GB `/srv` partition) as the Longhorn device, etcd stays on `/`.
+        Buildable today, zero spend, but re-creates the shared-spindle contention dev was burned by.
+      - **Repartition** into dedicated OS / etcd / Longhorn partitions. Better isolation, still one
+        physical failure domain.
+- [ ] **All three nodes get the identical layout.** Longhorn replica placement assumes symmetry.
+- [ ] Record the chosen device paths here and set them in
+      `infra/ansible/inventory/group_vars/k3s_prod/vars.yml` (they are deliberately
+      `/dev/BLOCKED-pending-disk-decision-…` placeholders today — do **not** guess). A full
+      `node-baseline` run against a node still carrying those placeholders now stops on an explicit
+      assert naming this section, instead of failing obscurely at `mkfs` time.
+- [x] **The SMART-vs-smartmontools circular dependency is broken** (2026-08-31). `roles/node_baseline`
+      is tagged `packages` / `system` / `disks`, so the package floor can land **without** the disk
+      tasks this decision blocks — see §5's drive-health box for the exact command.
+
+## 3. OS install (per node)
+
+- [ ] **Debian 13 (trixie)**, matching dev exactly — same kernel series, same package baseline.
+- [ ] Hostname `k3s-prod-N`.
+- [ ] Partition per the §2 decision.
+- [ ] **No cloud-init needed.** Dev's first-boot work was deliberately moved into
+      `roles/node_baseline` when provisioning became API-only (`infra/cloud-init/` is a README now),
+      so the same role covers bare metal. Nothing to port.
+
+## 4. Network (per node)
+
+- [ ] **Static IP** on the prod LAN, recorded in §0. Node 1 is `192.168.2.10/24`, gateway
+      `192.168.2.1`.
+- [x] **Prod address plan — DECIDED (operator, 2026-08-31).**
+
+      | Role | Address | Owned by |
+      |---|---|---|
+      | `k3s-prod-1` / `-2` / `-3` | `192.168.2.10` / `.11` / `.12` | Ansible inventory |
+      | **kube-vip control-plane VIP** | `192.168.2.9` | Ansible (`group_vars/k3s_prod`) |
+      | **Ingress Gateway VIP** (`GATEWAY_VIP`) | `192.168.2.20` | Flux (`clusters/prod`) |
+      | **Cilium L2 announcement pool** | `192.168.2.20` – `.30` | Flux (`platform-config/cilium`) |
+
+      Two deliberate properties, both mirroring dev:
+      - The **control-plane VIP sits outside the LB pool** (`.9`, below the nodes), so kube-vip and
+        Cilium LB-IPAM can never contend for the same address. Dev achieves this the other way
+        round (`.49` control-plane, pool `.53-.60`).
+      - **`GATEWAY_VIP` is the FIRST address of the pool.** Cilium LB-IPAM can only allocate from a
+        defined pool block, so a Gateway VIP outside every pool would not be allocatable — the pool
+        was widened from `.21-.30` to `.20-.30` for exactly this reason. Dev has the same shape
+        (`GATEWAY_VIP` `.53` = first of `.53-.60`).
+- [ ] **Reserve all of `192.168.2.9` and `.20-.30` outside any DHCP range** on the prod LAN before
+      the build, and confirm nothing else on the network already answers on them.
+- [ ] **Resolver: SECOND UPSTREAM IS AN OPEN DECISION — blocks `node-baseline.yml --tags dns`.**
+      Node 1 has a single IPv4 nameserver, `192.168.2.1`, which is also the LAN gateway. A single
+      upstream is a known SPOF that has already bitten this project — it broke containerd image
+      pulls and CoreDNS forwarding on dev.
+
+      The MECHANISM is now in the repo and needs no further work: the `dns`-tagged block in
+      `roles/node_baseline` detects whether a node uses systemd-resolved (dev: writes
+      `/etc/systemd/resolved.conf.d/99-k3s-dns.conf`, restarts resolved) or a directly-managed
+      `/etc/resolv.conf` (prod's shape: writes the file, refusing if resolvconf/NetworkManager
+      owns it), and configures the ordered upstream list either way. The earlier
+      `fix/node-dns-resilient-upstream` branch was **dropped, not merged** — it wrote a netplan
+      drop-in and ran `netplan apply`, and netplan is not installed on these Debian 13 trixie
+      nodes, so it would have broken `node-baseline.yml` on every host.
+
+      What is still MISSING is the VALUE. `group_vars/k3s_prod/vars.yml` sets
+      `node_baseline_dns_servers` to `192.168.2.1` followed by the deliberately invalid
+      `BLOCKED-pending-second-upstream-decision-see-PROD-PROVISIONING-md-4`, and the role's assert
+      stops the play on it before writing anything. Choosing the second upstream is a **network
+      decision, not a default the role may take**: a public resolver (`8.8.8.8`, `1.1.1.1`) would
+      resolve reliably but would also bypass any local zone and any filtering the gateway applies.
+      Decide between — and record the choice HERE, in the same change that edits the group_vars:
+      - a second on-LAN resolver on `192.168.2.x`;
+      - the dev-side PiHole `192.168.1.18`, **if** prod can actually route to it (unverified —
+        prod sits on the workstation side of the pfSense boundary);
+      - an explicit, written-down acceptance of a public resolver as fallback-only.
+
+      Also decide whether node 1's current IPv6 nameservers (`2001:4860:4860::8888` / `::8844`)
+      are kept: the direct-file write path replaces `/etc/resolv.conf` with exactly the listed
+      servers, so keeping them means listing them explicitly.
+      `node_baseline_dns_search` is `[]` (no search domain, node 1's behaviour today) until prod's
+      local domain is decided.
+- [ ] Confirm the prod LAN's relationship to the dev LAN (`192.168.1.x`) and to the pfSense NAT —
+      prod on `192.168.2.x` sits on the *workstation* side of the boundary dev lives behind.
+
+## 5. Access (per node) — **blocks all Ansible**
+
+- [ ] **`k3s` user with the `home_network` SSH key.** Working on node 1.
+- [ ] **Password-protected sudo, driven by Ansible `become` + a vaulted password.**
+      **Prod does NOT use NOPASSWD sudo** (operator decision, 2026-08-31). Dev nodes do; prod
+      deliberately keeps the sudo password in place and supplies it to Ansible as an
+      **ansible-vault-encrypted** var, exactly like the existing `hypervisor` and `proxmox_hosts`
+      groups:
+      ```
+      inventory/group_vars/k3s_prod/
+        README.md     how to (re)create the vault — committed
+        vault.yml     ansible_become_password: "..."  — committed, ENCRYPTED
+      ```
+      The passphrase that decrypts it lives **outside the repo** at
+      `~/.config/home-k3s/ansible-vault-pass` (`ansible.cfg :: vault_password_file`), so plays still
+      run unattended without a plaintext secret ever touching git.
+      ```bash
+      ansible-vault create inventory/group_vars/k3s_prod/vault.yml   # ansible_become_password: ...
+      ```
+      Prod nodes must therefore set `ansible_become: true` in their group_vars and must **not**
+      inherit any passwordless-sudo assumption from `group_vars/all.yml`.
+- [ ] **Drive health baseline** (§2). **Do not hand-install the tooling** — package installation is
+      the `node_baseline` role's job, never a manual `apt-get` on a node (operator ruling,
+      2026-08-31; same click-ops-never principle as the rest of the repo). `smartmontools` is part
+      of `node_baseline_packages`, so it arrives with the baseline play — but a *full* baseline
+      would hit the disk tasks §2 has not decided yet. Run the **packages-only** baseline instead
+      (the `disks`-tagged tasks, including the BLOCKED-device assert, are not selected at all, so
+      the placeholder device paths are never even templated):
+      ```bash
+      cd infra/ansible
+      ansible-playbook playbooks/node-baseline.yml \
+        -e k3s_hosts=k3s_prod --tags packages --limit k3s-prod-1
+      ```
+      (Needs `group_vars/k3s_prod/vault.yml` to exist first — the become password above.) Reading
+      the drive is then:
+      ```bash
+      sudo smartctl -a /dev/sda   # Power_On_Hours, Percent_Lifetime_Remaining, reallocated sectors
+      ```
+      Record the result in §2 and close the layout decision in the same change that replaces the
+      two `node_baseline_*_device` placeholders.
+
+## 6. Ansible baseline & cluster join
+
+Reuses the dev roles **unchanged** — that reuse **is** R-ENV-02. Only inventory and group_vars
+differ, plus a target-group override on the command line.
+
+### How prod is targeted (done, 2026-08-31)
+
+Every node-host play used to hardcode the literal dev groups `k3s_servers` / `k3s_primary` /
+`k3s_secondary`, so nothing here could select prod at all. Two knobs now close that, deliberately
+kept separate because Ansible resolves them at different times:
+
+| Layer | Knob | Set via |
+|---|---|---|
+| Which hosts a play **runs on** | `k3s_hosts`, `k3s_primary_hosts`, `k3s_secondary_hosts` (each defaults to the dev group) | `-e` **extra vars only** — a play's `hosts:` is templated before any host exists, so `group_vars` is not readable there |
+| Which group a **role** means by "my primary" / "my servers" | `k3s_primary_group`, `k3s_servers_group`, `cluster_kubeconfig_name` | `group_vars` — dev in `all.yml`, prod in `k3s_prod/vars.yml`; **no per-run flag** |
+
+So `roles/k3s_server` finds the prod `--cluster-init` founder, builds the prod join target and
+tls-san list, and `roles/cilium` fetches the prod kubeconfig, with **no role fork**. Running with
+no extra vars is byte-for-byte the dev behaviour it always had (verified by a before/after
+`--list-hosts` diff on every playbook). Full detail: `infra/ansible/README.md` → **Targeting prod**.
+
+- [x] Add a `k3s_prod` inventory group (`k3s_prod_primary` / `k3s_prod_secondary`). Prod is reached
+      **directly** on the LAN — no NAT port-forward hop, unlike dev's `192.168.2.102:225x` mapping.
+      (Nodes 2/3 stay commented out until they are physically on the bench.)
+- [x] `inventory/group_vars/k3s_prod/vars.yml`: `kube_vip_address` (`192.168.2.9`),
+      `cluster_controller_api_server`, `k3s_api_host`, the group-name overrides above — **and** the
+      §2 device overrides for `node_baseline_longhorn_device` / `node_baseline_etcd_device`, which
+      are still BLOCKED placeholders.
+- [ ] `inventory/group_vars/k3s_prod/vault.yml` — the vaulted `ansible_become_password` (§5). Until
+      it exists **no** prod play can escalate, and `--check` against prod cannot work either.
+- [ ] Run the **packages-only** baseline first, to unblock the §2 drive-health read:
+      ```bash
+      ansible-playbook playbooks/node-baseline.yml -e k3s_hosts=k3s_prod --tags packages
+      ```
+- [ ] Run the **full** `playbooks/node-baseline.yml -e k3s_hosts=k3s_prod` → packages, kernel
+      modules, sysctls, iscsid, data-disk filesystems + mounts. **Blocked until §2 is decided**: it
+      asserts on the placeholder device paths and stops. (`qemu-guest-agent` is a no-op on bare
+      metal — the role already only *starts* it when the virtio channel exists, so it degrades
+      cleanly.)
+- [ ] Run `playbooks/k3s.yml -e k3s_primary_hosts=k3s_prod_primary -e k3s_secondary_hosts=k3s_prod_secondary`
+      → HA embedded etcd, flannel/kube-proxy/Traefik/servicelb disabled. **Only once all three
+      nodes are present** — see §8.
+- [ ] Run `playbooks/kube-vip.yml -e k3s_hosts=k3s_prod` → control-plane VIP (`192.168.2.9`) on the
+      prod LAN.
+- [ ] Run `playbooks/cilium.yml -e k3s_hosts=k3s_prod` → CNI at bootstrap; Flux's HelmRelease adopts
+      it afterwards. The bootstrap values and the HelmRelease **must stay in parity**
+      (`kubeProxyReplacement`, `k8sServiceHost`/`Port`) or the two layers fight over CNI config
+      (`docs/02`). Note the prod kubeconfig is fetched to `.cache/prod.kubeconfig`, never over the
+      dev one the dev container exports as `$KUBECONFIG`.
+- [ ] Run `playbooks/verify.yml -e k3s_hosts=k3s_prod`.
+- [ ] `playbooks/flux-bootstrap.yml -e k3s_hosts=k3s_prod` **retargets but is not yet correct**:
+      `roles/flux_bootstrap` shells out to `bootstrap/flux/bootstrap.sh`, which bootstraps
+      `--path=clusters/dev`. Prod needs `--path=clusters/prod` — a `bootstrap/` change, not a
+      target-group change. Tracked with the other repo blockers in §7.
+- [ ] Decide whether prod runs a VPN egress gateway node (dev uses `k3s-dev-3`, ADR-0015).
+      `playbooks/vpn.egress.gateway.yml` takes `-e vpn_egress_gateway_hosts=<group>`, but there is
+      deliberately no prod egress group in the inventory yet, and it would need its **own** vaulted
+      PIA credentials — the existing vault is scoped to the dev group.
+
+## 7. Repo blockers — **prod cannot be reconciled until these land**
+
+`clusters/prod` is design-only today and **would build wrong**. R-ENV-02 promises dev and prod differ
+*only* by `cluster-vars` values; in practice dev LAN addresses are hardcoded into base manifests:
+
+| Hardcoded value | Where | Prod needs |
+|---|---|---|
+| `k8sServiceHost: 192.168.1.50` | `platform/cilium/helmrelease.yaml:50`, mirrored in `values.yaml:16` | prod primary node IP |
+| LB pool `192.168.1.53–.60` | `platform-config/cilium/l2-ip-pool.yaml:15` | a prod-LAN pool |
+| `192.168.1.55` (crafty) | `platform/crafty/service-l4.yaml` | prod-LAN address |
+| `192.168.1.54` (UniFi VM) | `apps/vms/unifi/50-service-l4.yaml` | prod-LAN address |
+| `192.168.1.9:9000` (S3 backup) | `platform/keycloak/postgres-cluster.yaml`, `apps/wave-0/{nextcloud,semaphore}-db.yaml` | reachable prod backup target |
+
+- [ ] **Tokenize each into a `cluster-vars` knob** with a base default, then set the value in *both*
+      overlays. Adding a knob before referencing `${KNOB}` is the sanctioned mechanism (see the
+      header comment in `clusters/base/cluster-vars.yaml`). `platform`, `platform-config`, the app
+      waves, `apps-vms` and `crafty` all already carry `postBuild.substituteFrom: cluster-vars`, so
+      the seam exists.
+- [ ] **`clusters/prod` must set `GATEWAY_VIP`.** It currently doesn't, so prod would inherit the
+      base default `10.73.0.240` — an address from the **retired libvirt network**. The base file's
+      own comment flags this as owed "when hardware is built."
+- [ ] **Dev overlay sets every new knob to today's exact value** so rendered dev output is
+      byte-identical and the live cluster sees zero drift. Verify with `make -C ci render-golden`.
+- [ ] **`clusters/prod` is NOT bootstrappable as-is** — three gaps, found 2026-09-01 while landing
+      the `dependsOn` fix. Only the first is now closed:
+      - [x] **Root Kustomization** — `clusters/prod/sync.yaml` authored, mirroring dev. This became
+            *load-bearing*, not cosmetic: `clusters/base/platform.yaml` now carries
+            `dependsOn: [flux-system]`, so without a root object on prod, `platform` would block
+            forever on a dependency that does not exist and nothing downstream would reconcile.
+      - [x] **SOPS decryption** — DONE. Operator decision 2026-09-01: **prod uses the SAME age key
+            as dev**. Eight `decryption: {provider: sops, secretRef: sops-age}` patches mirror dev
+            exactly. The `sops-age` Secret is still created OUT OF BAND on the prod cluster
+            (`bootstrap/sops/install-age-key.sh`) — the overlay references it by name only.
+      - [~] **GitRepository source** — BRANCH settled, URL still blocked. Operator decision
+            2026-09-01: **prod tracks `main`, the same branch as dev**, because dev is temporary and
+            will be decommissioned once prod is stable. Recorded consequence: once prod is live,
+            **every merge to `main` reconciles BOTH clusters** — no promotion step, no soak window.
+            The URL is patched in but **cannot work on a cold prod cluster**, for two independent
+            reasons found 2026-09-01:
+            1. **Self-hosting circularity** — Gitea runs on the DEV cluster, the one slated for
+               decommission. Gitea must move to prod (or off-cluster) BEFORE dev is retired, or prod
+               loses its source of truth. **This is the decommission plan's first task, not its last.**
+            2. **Split-horizon sends it to the wrong place** — `coredns-custom` answers the entire
+               `home.keithjackson.dev` zone with `${GATEWAY_VIP}`, which on prod is `192.168.2.20`:
+               prod's OWN gateway, where no Gitea listens. Prod's Flux would resolve
+               `gitea.home.keithjackson.dev` to itself and never reach a repository.
+            Bring-up needs a TEMPORARY source (bootstrap host-Gitea, or an off-cluster mirror) and a
+            cutover once Gitea runs on prod — the same sequence `docs/05` describes for dev's own
+            Phase-6 cutover.
+- [ ] Confirm prod's backup target: dev's S3 (`versitygw` on the Proxmox host, `192.168.1.9`) is on
+      the dev side of the network. Off-cluster backup is DR-critical (R-STATE-03).
+
+## 8. Build sequence (operator decision, 2026-08-31: **wait for all three nodes**)
+
+Node 1 is baselined now; the cluster is **not** initialized until nodes 2 and 3 are on the bench.
+This keeps prod spec-conformant (3-node HA embedded etcd) from its first boot, avoids a
+single-server-etcd window, and avoids a later member-add dance.
+
+1. Per-node §1–§5 on each of the three boxes.
+2. §7 repo work lands on `main` with the gate green.
+3. `node-baseline` → `k3s` (all three) → `kube-vip` → `cilium`.
+4. `flux bootstrap ... --path=clusters/prod`.
+5. Conformance against prod (§9).
+
+## 9. Exit criteria (Phase 7)
+
+- [ ] Prod runs the same config as dev via the prod overlay, **no base edits** (R-ENV-02).
+- [ ] Node destroy/rebuild from IaC + Ansible without data loss (R-ENV-01, R-STATE-01).
+- [ ] Full **automated** prod DR drill (R-STATE-03) — `definition-of-done.md` requires this for prod
+      specifically.
+- [ ] Monitoring and alerts live on prod.
+- [ ] The conformance suite passes green **against the prod cluster**, not just dev (R-TEST-03).

+|---|---|
+| `node-baseline.yml` | packages (incl. `cryptsetup`), kernel modules, Longhorn disk, swap-off |

+
+`inventory/hosts.ini` carries a `[k3s_prod_primary]` / `[k3s_prod_secondary]` /
+`[k3s_prod:children]` section for the three planned bare-metal nodes (`k3s-prod-1` at

+(vaulted `ansible_become_password` + non-secret overrides).
+
+**Nothing here is forked for prod.** Every node-host play takes its target group from a variable
+that defaults to the dev group, so the dev commands above are unchanged, and prod is the same
+command plus an override. Two separate mechanisms, for two separate reasons:
+
+| Layer | Knob | Set via | Why |
+|---|---|---|---|
+| Which hosts a play **runs on** | `k3s_hosts`, `k3s_primary_hosts`, `k3s_secondary_hosts`, `vpn_egress_gateway_hosts` | `-e` **extra vars only** | Ansible templates a play's `hosts:` *before* it has any host, so it cannot see `group_vars` at all |
+| Which group a **role** means by "my primary" / "my servers" | `k3s_primary_group`, `k3s_servers_group` (+ `cluster_kubeconfig_name`) | `group_vars` — dev in `all.yml`, prod in `k3s_prod/vars.yml` | Host context exists by then, so each environment answers for itself with **no per-run flag** — same mechanism `k3s_api_host` already used |
+
+`playbooks/node-health.yml` established the first pattern (`-e node_health_hosts=k3s_prod`); it
+keeps its own var name because it is a standalone diagnostic you point anywhere, not part of the
+bring-up chain.
+
+```bash
+# dev — completely unchanged, no extra vars
+ansible-playbook playbooks/site.yml
+
+# prod — one flag for the whole-cluster plays
+ansible-playbook playbooks/node-baseline.yml   -e k3s_hosts=k3s_prod

+  -e k3s_primary_hosts=k3s_prod_primary \
+  -e k3s_secondary_hosts=k3s_prod_secondary
+```
+
+What the roles then resolve **by themselves** for a prod host, from `group_vars/k3s_prod/vars.yml`:
+`k3s_primary_group=k3s_prod_primary` (the `--cluster-init` founder, the node-token `delegate_to`
+target, and the node Cilium fetches the kubeconfig from), `k3s_servers_group=k3s_prod` (the tls-san
+node-IP list), `k3s_api_host=192.168.2.10`, `kube_vip_address=192.168.2.9`, and
+`cluster_kubeconfig_name=prod.kubeconfig` — so a prod run can never overwrite the
+`.cache/dev.kubeconfig` that `infra/devcontainer/dev.sh` exports as `$KUBECONFIG`.
+
+### Packages-only baseline (`--tags packages`)
+`roles/node_baseline` is tagged `packages` / `system` / `disks`. An untagged run is unchanged (all
+three, in order). `--tags packages` runs **only** the apt task:
+
+```bash
+ansible-playbook playbooks/node-baseline.yml -e k3s_hosts=k3s_prod --tags packages --limit k3s-prod-1
+```
+
+This exists to break a circular dependency: prod's disk layout (`infra/PROD-PROVISIONING.md` §2) is
+blocked on a SMART read, SMART needs `smartmontools`, `smartmontools` ships in
+`node_baseline_packages` — but the role's disk tasks need block devices that decision hasn't chosen
+yet. With `--tags packages` no `disks`-tagged task is selected, so the deliberate
+`/dev/BLOCKED-pending-disk-decision-…` placeholders in `group_vars/k3s_prod/vars.yml` are never
+even templated, let alone handed to `mkfs`. A **full** run against a node whose devices are still
+placeholders stops on an explicit assert naming §2 instead of failing obscurely at mkfs time. Never
+hand-install packages on a node — that is this role's job (operator ruling, 2026-08-31).
+
+### Still not runnable end to end
+- The **disk-layout** (§2) and the `node_baseline_*_device` overrides remain BLOCKED placeholders.
+- `group_vars/k3s_prod/vault.yml` (the become password) does not exist yet, so **no** prod play can
+  escalate — and `--check` against prod fails for the same reason.
+- `flux-bootstrap.yml` retargets, but `roles/flux_bootstrap` shells out to
+  `bootstrap/flux/bootstrap.sh`, which bootstraps `--path=clusters/dev`. Prod needs
+  `--path=clusters/prod`: a `bootstrap/` change, not a target-group change (§7).
+- `vpn.egress.gateway.yml` is parameterised (`-e vpn_egress_gateway_hosts=…`) but prod has **no**
+  egress group yet — whether prod runs one at all is an open §6 decision, and it would need its own
+  vaulted PIA credentials.
+- The operator has ruled the prod cluster stays **uninitialized** until all three nodes are present
+  (§8). `192.168.2.20` is prod's *ingress* Gateway VIP — a Flux/`cluster-vars` concern, not an
+  Ansible one; the kube-vip **control-plane** VIP is `192.168.2.9` (`kube_vip_address`).
+
+Everything above this section describes the **dev** runbook; the values in it (`192.168.1.x`,
+`.cache/dev.kubeconfig`, `clusters/dev`) are dev's, supplied by `group_vars`, not baked into the
+roles.

+**ansible-vault-encrypted** var here — it is encrypted, so it is safe to commit; the passphrase
+that decrypts it stays out of the repo, exactly like the existing `hypervisor` and `proxmox_hosts`
+groups.
+
+## Two files (one committed-encrypted, one never committed)
+
+1. **The vault passphrase** — a file **outside the repo**, referenced by `ansible.cfg`
+   (`vault_password_file = ~/.config/home-k3s/ansible-vault-pass`). Skip this if you already made
+   one for the `hypervisor` or `proxmox_hosts` vaults — it's the SAME passphrase file, shared by
+   every vaulted group in this repo:
+   ```bash
+   mkdir -p ~/.config/home-k3s
+   install -m600 /dev/stdin ~/.config/home-k3s/ansible-vault-pass <<<'YOUR_VAULT_PASSPHRASE'
+   ```
+
+2. **The encrypted become password** — `vault.yml` in **this directory** (committed, encrypted).
+   `vault.yml.example` alongside it shows the exact shape (see it for the reasoning); copy its
+   content, fill in the real password, then encrypt it in place — do not commit the `.example`
+   content unencrypted as `vault.yml`:
+   ```bash
+   cd infra/ansible
+   ansible-vault create inventory/group_vars/k3s_prod/vault.yml
+   # file content (single line):
+   #   ansible_become_password: "THE k3s USER'S SUDO PASSWORD ON k3s-prod-1"
+   ```
+   (`ansible-vault create` uses the passphrase file above automatically — no prompt.)
+
+Once `vault.yml` exists, prod plays run unattended — same as dev, just with a real sudo boundary
+behind them instead of NOPASSWD.
+
+## Notes
+- `vault.yml` is skipped by the yamllint gate (`ci/yamllint.yaml` ignores `**/vault.yml`) because a
+  vault blob is not parseable YAML. `vault.yml.example` is plain YAML and IS linted — it's a
+  copy-paste scaffold, not a secret (same convention as
+  `platform/backup/minio-credentials.sops.yaml.example`).
+- The k3s **dev** nodes keep passwordless sudo unchanged — this vault is scoped to the `k3s_prod`
+  group only.
+- `ansible_become: true` for this group is set explicitly in `vars.yml` (this directory) — belt
+  and braces alongside the playbooks' own `become: true`, so prod's posture is self-documenting
+  and doesn't rely on inheriting anything from `group_vars/all.yml` by accident.
+- Non-secret prod vars live in `vars.yml`, not here — this README is scoped to the vault hand-off.
+  `k3s_api_host` is set to a real value. `kube_vip_address`, `cluster_controller_api_server`,
+  `node_baseline_longhorn_device` and `node_baseline_etcd_device` are all still-BLOCKED
+  placeholders pending operator decisions (control-plane VIP and disk layout, respectively) — see
+  `vars.yml`'s comments for what IS already decided (node addresses, the separate *ingress* VIP,
+  which is a Flux/`cluster-vars` concern and does not live here) versus what is not.
+- This is the Ansible-bootstrap-layer secret (host credential), distinct from the platform's
+  in-cluster **SOPS + age** secrets (ADR-0007) — different layer, different tool, same convention
+  as `hypervisor`/`proxmox_hosts`.
+- **Targeting prod is solved** (2026-08-31): plays take `-e k3s_hosts=k3s_prod` (and, for `k3s.yml`,
+  `-e k3s_primary_hosts=k3s_prod_primary -e k3s_secondary_hosts=k3s_prod_secondary`), while the
+  roles resolve "my environment's primary/servers" from `k3s_primary_group` / `k3s_servers_group`
+  in `vars.yml` here — no role fork, no per-run flag for that half. See
+  `infra/ansible/README.md` → "Targeting prod".
+- **Do not run any prod playbook yet.** Phase 7 is prep-only: the vault above just makes the plays
+  *able* to authenticate once the §7 repo blockers close and the disk-layout (§2) decision in
+  `infra/PROD-PROVISIONING.md` is made. The ONE exception the operator has sanctioned is the
+  packages-only baseline that unblocks the §2 drive-health read —
+  `ansible-playbook playbooks/node-baseline.yml -e k3s_hosts=k3s_prod --tags packages` — which
+  cannot touch the BLOCKED device placeholders because every disk task is `disks`-tagged and so is
+  not selected. It still needs `vault.yml` (above) to exist first.

+# all.yml carries no explicit `ansible_become` of its own (dev's passwordless sudo

+# and every node-host playbook already sets `become: true` at the play level
+# (node-baseline.yml, k3s.yml, cilium.yml, kube-vip.yml) — for dev that silently
+# succeeds because sudo needs no password there. Setting ansible_become explicitly
+# here is belt-and-braces: this group's posture is self-documenting and does not rely

+ansible_become: true
+# The password itself is ansible_become_password — ansible-vault-encrypted, in
+# vault.yml (this directory), never here in plaintext. See README.md to create it.
+
+# --- environment group NAMES (R-ENV-02) -------------------------------------------
+# group_vars/all.yml defines these as the DEV group names (k3s_primary / k3s_servers);
+# here they name PROD's groups. Roles index `groups[k3s_primary_group]` /
+# `groups[k3s_servers_group]` instead of a literal, so roles/k3s_server and roles/cilium
+# resolve "my environment's primary" and "my environment's servers" correctly for prod
+# hosts with NO role fork and no per-run flag — the reuse R-ENV-02 promises.
+#
+# NOTE these are GROUP NAMES, not the play-level target pattern. Selecting which hosts a

+# k3s.yml `-e k3s_primary_hosts=k3s_prod_primary -e k3s_secondary_hosts=k3s_prod_secondary`),

+# value set below automatically for prod hosts too.
+
+# --- control-plane VIP + controller access — DECIDED (§4) -------------------------
+# Prod addressing, all decided by the operator 2026-08-31:
+#   nodes k3s-prod-1/2/3   192.168.2.10 / .11 / .12   (hosts.ini)
+#   control-plane VIP      192.168.2.9                (THIS value — kube-vip, Ansible-side)
+#   ingress Gateway VIP    192.168.2.20               (Flux/cluster-vars — NOT here)
+#   ingress L2 pool        192.168.2.20 - .30         (Flux/cluster-vars — NOT here)
+#
+# The control-plane VIP sits BELOW the node addresses and deliberately OUTSIDE the
+# Cilium LB pool (.20-.30), so kube-vip and Cilium LB-IPAM can never contend for the
+# same address. That separation is the point: dev learned the same shape the other way
+# round (control-plane .49, ingress pool .53-.60).
+#
+# This is the address kube-vip floats for the API and that k3s tls-san's onto its
+# serving cert; secondaries use it as their --server join target. Dev's equivalent is
+# kube_vip_address: 192.168.1.49 in group_vars/all.yml.
+#
+# HISTORY: an earlier pass here wrongly set this to 192.168.2.20 — that is the INGRESS
+# VIP, not the control-plane VIP. Corrected. Keep the two distinct.
+kube_vip_address: "192.168.2.9"
+# Derived from kube_vip_address above (not repeated), so fixing the one line above is
+# the only change needed once a real control-plane VIP is chosen. Prod has no NAT hop

+# roles/node_baseline defaults (node_baseline_longhorn_device: /dev/vdb,
+# node_baseline_etcd_device: /dev/vdc) assume tofu-provisioned virtio disks that DO

+# as hard, but says exactly why, and blocks a `find`/glob from accidentally matching

+# --- node_baseline DNS upstreams — SECOND UPSTREAM BLOCKED, open decision (§4) -----
+# roles/node_baseline defaults are DEV's list (192.168.1.18 PiHole, then 192.168.1.1
+# pfSense) — addresses on a network prod cannot even reach. Inherited verbatim they would
+# point every prod node at a PiHole that does not answer it, so they are overridden here,
+# in the same seam as kube_vip_address / k3s_api_host / cluster_kubeconfig_name above.
+# (NOT clusters/base/cluster-vars.yaml: that ConfigMap is consumed by Flux
+# postBuild.substituteFrom for platform/ and apps/ manifests, and no Ansible code reads it.)
+#
+# WHAT IS DECIDED: 192.168.2.1 — node 1's current sole nameserver, and the LAN gateway.
+# It stays FIRST, so whatever local zone it serves keeps working (the dev outage taught
+# that ordering is policy, not preference — see the role's defaults).
+#
+# WHAT IS NOT: the SECOND upstream. 192.168.2.1 is presently gateway AND only IPv4
+# resolver, and there is no second address on this LAN that is known to answer. Picking
+# one is a NETWORK decision, not a default this role may take: a public resolver
+# (8.8.8.8, 1.1.1.1) would resolve reliably but would ALSO bypass any local zone and any
+# network-level filtering the gateway applies — precisely the bypass the dev fix refused
+# to make. Candidates the operator must choose between and record in
+# infra/PROD-PROVISIONING.md §4: a second on-LAN resolver, the dev-side PiHole IF prod can
+# route to 192.168.1.18, or an explicit, written-down decision to accept a public resolver
+# as fallback-only.
+#
+# Deliberately present-but-broken, exactly like node_baseline_longhorn_device above:
+# leaving the list at one entry, or unset, would either configure the very SPOF this exists
+# to remove or silently inherit dev's PiHole. This value can never parse as an address, and
+# the `dns`-tagged assert in roles/node_baseline stops the play on the string BLOCKED
+# before a single file is written. DO NOT replace it with a guess — replace it only once
+# §4 is decided, and record the chosen resolver there in the SAME change.
+#
+# Note the two Google IPv6 servers currently in node 1's /etc/resolv.conf
+# (2001:4860:4860::8888/::8844) are NOT carried over: the direct-file write path replaces
+# the file with exactly this list, so if they are to be kept they must be listed here
+# explicitly — as part of that same recorded decision.
+node_baseline_dns_servers:
+  # DECIDED (operator, 2026-09-01): prod's resolvers are PUBLIC and deliberately differ
+  # from dev's. Dev is PiHole-first (192.168.1.18) because dev needs the local jackson.lan
+  # zone AND split-horizon *.home.keithjackson.dev. Prod has no local resolver on its LAN,
+  # so it takes two INDEPENDENT public upstreams — which resolves the single-upstream SPOF
+  # (a single upstream broke containerd image pulls and CoreDNS forwarding on dev).
+  - "8.8.8.8"
+  - "1.1.1.1"
+  # SCOPE — this file sets NODE resolution only: containerd image pulls, and the upstream
+  # CoreDNS forwards `.` to. Three different resolvers answer *.home.keithjackson.dev, and
+  # only ONE of them is configured here:
+  #
+  #   pods (in-cluster) -> CoreDNS -> platform/coredns/coredns-custom.yaml, whose `template`
+  #       plugin answers the WHOLE home.keithjackson.dev zone with ${GATEWAY_VIP}. Entirely
+  #       self-contained in the cluster; PiHole is NOT in this path. Prod is already correct
+  #       (GATEWAY_VIP = 192.168.2.20 in clusters/prod).
+  #   LAN clients       -> PiHole. Not a cluster concern.
+  #   nodes             -> THIS FILE. Public resolvers, so the zone resolves PUBLICLY.
+  #
+  # THE ONE THING THAT BREAKS: the k3s API SERVER is a node process and carries
+  # `oidc-issuer-url=https://keycloak.home.keithjackson.dev/realms/homelab`
+  # (roles/k3s_server/tasks/main.yml). It reaches the issuer through the NODE resolver, so on
+  # prod it would get the PUBLIC record instead of the prod Gateway VIP — breaking kubectl
+  # OIDC SSO. Dev avoids this because its node resolver is PiHole, which answers the zone
+  # with the dev Gateway VIP.
+  #
+  # NOT blocking today (prod has no cluster and no Keycloak yet). Options, in
+  # PROD-PROVISIONING.md §4: a narrow Ansible-managed /etc/hosts entry pinning
+  # keycloak.home.keithjackson.dev -> 192.168.2.20 on prod nodes; or a local resolver on the
+  # prod LAN serving the zone; or run prod on the cert kubeconfig and defer OIDC.
