fix(arrs): the config PVC was mounted where the app never looks

sonarr, radarr, jackett and qbittorrent all mounted their Longhorn config PVC at
the renderer's default /data/config, but every one of these images runs with
`-data=/config`. So the PVC held nothing but lost+found while the app wrote its
entire configuration to the container's EPHEMERAL writable layer — destroyed on
every pod recreation: restart, reschedule, image bump.

Measured in-cluster before fixing, per app, rather than inferred:
  /data/config  dev=2080  [lost+found]                      <- the Longhorn PVC
  /config       dev=2053  [Sentry asp config.xml logs ...]   <- the node's own disk
and a marker file written to /config did not appear in /data/config, so they are
demonstrably different storage. qbittorrent's /config sat on dev=66309
(/dev/nvme0n1p5), i.e. whichever node it happened to land on.

This is the SAME failure catalog/plex.yaml:54 already records having fixed for
Plex; plex was the only one of the five that was right.

The live /config contents were copied onto each PVC BEFORE this landed, so
jackett's API key and qbittorrent's credentials — which other apps reference —
survive the move rather than being regenerated.

catalog/sonarr.yaml:61 documented this as a latent bug and deliberately left it
because it changes live on-disk state. It is being fixed now because all four pods
had just been recreated, so their configs were freshly generated and nothing had
accumulated to lose.

@@ -1758,3 +1758,334 @@ into a transient hard Kustomization failure.
 - **Prod's source URL cannot work on a cold prod cluster** — split-horizon answers the whole zone
   with `${GATEWAY_VIP}`, so prod would resolve `gitea.home.keithjackson.dev` to its own gateway.
   Bring-up needs a temporary source and a cutover, as `docs/05` describes for dev's own Phase-6.
+
+## 2026-09-07 — LIVE BUG: prod's OIDC clients were pointed at DEV's Keycloak. Secrets are a substitution blind spot.
+
+The operator could not log in to Headlamp on prod:
+
+```
+Get "https://keycloak.home.keithjackson.dev/realms/homelab/.well-known/openid-configuration":
+dial tcp 192.168.1.53:443: i/o timeout
+```
+
+`keycloak.home.keithjackson.dev` is **dev's** Keycloak. It resolves to `192.168.1.53`, on the dev
+LAN behind pfSense; prod lives on `192.168.2.0/24` (pfSense's WAN) and cannot route there, so the
+discovery fetch simply hung until it timed out.
+
+### Root cause — the class, not the instance
+
+**Flux's `${BASE_DOMAIN}` postBuild substitution rewrites the RENDERED MANIFEST TEXT. It can never
+reach inside a SOPS-encrypted Secret.** Environment-specific URLs had been stored *inside* two
+encrypted Secrets purely because it was convenient to keep one blob per app:
+
+| File | Buried, un-substitutable values |
+|---|---|
+| `platform/headlamp/headlamp-oidc-credentials.sops.yaml` | `OIDC_ISSUER_URL`, `OIDC_CALLBACK_URL` |
+| `apps/wave-1/semaphore-bootstrap-secret.sops.yaml` (`oidc-providers-json`) | the realm issuer + the OIDC redirect URI |
+
+Both were frozen at the apex `home.keithjackson.dev`. **Dev IS the apex, so dev was correct by
+coincidence** — the values were never per-environment, they just happened to match one environment.
+Prod was wrong from the first reconcile. Semaphore on prod was broken the same way and nobody had
+noticed, because nobody had tried prod SSO yet.
+
+This is the same failure shape as the 2026-09-01 nextcloud guard: **a value that silently resolves
+to something plausible is worse than one that fails.** `StrictPostBuildSubstitutions` cannot catch
+it either — there is no `${...}` left unresolved to complain about; the ciphertext never contained
+one.
+
+### The rule this establishes
+
+> **Non-secret, environment-specific values MUST NOT live inside an encrypted Secret.** Issuer URLs,
+> callback URLs, redirect URIs and hostnames are public. Encrypt the secret half only, and template
+> the rest where `${BASE_DOMAIN}` can reach it.
+
+### The fix
+
+- **Headlamp** — `OIDC_ISSUER_URL` / `OIDC_CALLBACK_URL` moved to the HelmRelease's
+  `spec.values.env`, templated `${BASE_DOMAIN}`. The Secret keeps `OIDC_CLIENT_SECRET` +
+  the environment-invariant `OIDC_CLIENT_ID` / `OIDC_SCOPES`, still `envFrom`'d.
+  **Exactly one source per variable** — an explicit `env:` entry silently outranks the same name
+  arriving via `envFrom`, so the two sets deliberately do not overlap.
+  Side effect, intended: naming `OIDC_CALLBACK_URL` in `env:` makes chart 0.41.0 finally emit
+  `-oidc-callback-url=$(OIDC_CALLBACK_URL)`; it gates that arg on `env:`/`config.oidc`, which a
+  Secret key alone never tripped — so the Secret's callback URL had been dead weight all along.
+- **Semaphore** — the `SEMAPHORE_OIDC_PROVIDERS` JSON is now a plaintext literal in
+  `catalog/semaphore.yaml` (re-rendered to the `apps/wave-1` golden). Only the client secret stays
+  encrypted, in its own key `oidc-client-secret`, and the **kubelet** splices it back via
+  dependent-env-var expansion: `$(SEMAPHORE_OIDC_CLIENT_SECRET)` resolves against the `secretKeyRef`
+  env var declared immediately above it. **Order is load-bearing** — the kubelet resolves `env` in
+  list order and leaves a forward reference as literal text. `flux envsubst` ignores `$(...)`, so
+  the two expansion layers do not collide (the `$${VAR}` escape in `apps/wave-1/nextcloud.yaml`
+  documents the one form that DOES need escaping).
+
+### Proof
+
+Rendered per overlay (`kubectl kustomize --load-restrictor LoadRestrictionsNone`, then
+`flux envsubst --strict` with that overlay's `cluster-vars`), plus `helm template` of headlamp
+0.41.0 against the substituted values:
+
+| | dev | prod |
+|---|---|---|
+| Headlamp `OIDC_ISSUER_URL` | `https://keycloak.home.keithjackson.dev/realms/homelab` | `https://keycloak.prod.home.keithjackson.dev/realms/homelab` |
+| Headlamp `OIDC_CALLBACK_URL` | `https://headlamp.home.keithjackson.dev/oidc-callback` | `https://headlamp.prod.home.keithjackson.dev/oidc-callback` |
+| Semaphore `provider_url` | `https://keycloak.home.keithjackson.dev/realms/homelab` | `https://keycloak.prod.home.keithjackson.dev/realms/homelab` |
+| Semaphore `redirect_url` | `https://semaphore.home.keithjackson.dev/api/...` | `https://semaphore.prod.home.keithjackson.dev/api/...` |
+
+Dev's values are byte-identical to what it runs today — this change moves prod only.
+
+### [parity] the apiserver invariant HOLDS
+
+Prod's kube-apiserver `oidc-issuer-url` is an **install-time k3s flag** derived from
+`k3s_base_domain` (`infra/ansible/inventory/group_vars/k3s_prod/vars.yml` = `prod.home.keithjackson.dev`),
+not from `cluster-vars` — it cannot read the Flux variable. Headlamp forwards the user's `id_token`
+to the apiserver, so the two must name the same issuer. After this change they do, in both
+environments, because both derive from the same per-environment domain. Unchanged risk, now written
+down in `platform/headlamp/README.md`: moving one without the other 401s every request.
+
+### Also fixed for the next person
+
+`headlamp-oidc-credentials.sops.yaml.example` used to *teach* the broken pattern — it listed
+`OIDC_ISSUER_URL` and `OIDC_CALLBACK_URL` as keys to fill in. It now says, in the file, that adding
+either key back re-breaks prod.
+## 2026-09-07 — k3s-prod-1 NotReady: etcd starved of disk I/O by Longhorn (branch `fix/etcd-io-priority`)
+
+**06:05:21Z, `k3s-prod-1` went NotReady** (`Kubelet stopped posting node status`) with the host
+up, pingable and SSH-able. The embedded etcd could not complete a WAL `fdatasync`:
+
+```
+slow fdatasync                took=3.56s / 6.71s / 4.95s / 3.40s   (etcd expects 1s)
+apply request took too long   took=8.30s                           (expects 100ms)
+etcdserver: too many requests
+Failed to check local etcd status for learner management: context deadline exceeded
+```
+
+No OOM, no MCE, no hung task — **this is not the §0b memattr bug and not memory**. It is the §2
+shared-device risk, which §2 recorded as "accepted to be MEASURED, not assumed". The measurement
+came back, in production, 2 d 7 h after bring-up. `/proc/pressure/io` **full avg300**: node 1
+**11.36**, node 2 (NVMe) 0.75, node 3 (WD Blue SATA) 1.29. Node 1's drive is a 2011
+`C400-MTFDDAC512MAM` with 61,440 reallocated sectors and no power-loss protection. §2's premise —
+"every prod node is SSD or NVMe, where rebuild I/O costs latency rather than collapsing it" — was
+right about node 2 and wrong about node 1. §2 now records this under "THE MEASUREMENT CAME BACK".
+
+**The exit condition is OPEN and the fix is hardware: replace node 1's drive, or give etcd its own
+device (`node_baseline_etcd_source: device`, the path the role still supports). That is the
+operator's.** Three software mitigations shipped meanwhile, none of which is the fix.
+
+### 1. The outage was invisible to the monitoring stack — fixed first
+
+There were alerts for **CPU** PSI and memory and **none for I/O**, so the first signal was a node
+already out of the cluster. Added `NodeIOPressureHigh` (full IO PSI > 5% for 10m) and
+`NodeIOPressureCritical` (> 10% for 5m), thresholds taken from the numbers above against a ~1%
+steady state, plus an I/O row on the node-pressure dashboard. Verified live that node-exporter
+already exports `node_pressure_io_{stalled,waiting}_seconds_total` on all three nodes.
+
+**Gap left open for the operator:** etcd's own `etcd_disk_wal_fsync_duration_seconds` — the metric
+§2's exit condition literally asks for — is **not collected**. `kubeEtcd` is deliberately disabled
+in `platform/monitoring/kube-prometheus-stack.yaml` for k3s. Enabling it (k3s
+`--etcd-expose-metrics` + a scrape target) would make §2 directly measurable instead of inferred
+from PSI. Not done here: it is a k3s server-flag change requiring a rolling restart, which is not
+something to bundle into an incident fix.
+
+### 2. Longhorn was already throttled as far as Longhorn goes
+
+`concurrentReplicaRebuildPerNodeLimit: 1` was **in force during the outage and it held** — the 18
+volumes rebuilt one at a time and the node stalled anyway. Recorded plainly because it would be
+easy to "fix" this incident by setting a knob that was already set. For the v1 data engine there is
+no further rebuild lever: `replicaRebuildingBandwidthLimit` is v2/SPDK only (live Setting reads
+`{"v2":"0"}`, no v1 key) and `rebuildConcurrentSyncLimit` is already at its floor of 1.
+
+So what was tightened is every *other* Longhorn I/O source, each defaulting to 5 concurrent
+operations per node: `concurrentVolumeBackupRestorePerNodeLimit` 5→1 (an R-STATE-03 restore of 18
+volumes would otherwise run five parallel full-volume writes onto the disk etcd fsyncs to),
+`snapshotHeavyTaskConcurrentLimit` 5→1, plus pins on `replicaReplenishmentWaitInterval`,
+`backup`/`restoreConcurrentLimit` and `concurrentAutomaticEngineUpgradePerNodeLimit`.
+
+**And one setting in that file was inert.** `orphanAutoDeletion: true` has been silently dropped
+since the 1.11→1.12 upgrade — Longhorn 1.9 renamed it `orphanResourceAutoDeletion` (a list, not a
+bool) and the chart drops unknown `defaultSettings` keys with no error. Confirmed from both ends:
+absent from chart v1.12.1's `templates/default-setting.yaml`, and absent from the rendered
+`longhorn-default-setting` ConfigMap in the live cluster. Removed, deliberately not replaced. That
+is the **third** time this repo has shipped config that looked applied and was not.
+
+### 3. Block-layer arbitration — and four mechanisms that are inert on these nodes
+
+`roles/etcd_io_priority` + `playbooks/etcd-io-priority.yml`: BFQ on the shared disk, `nr_requests`
+64→32, `IOWeight=10000` on `system.slice` **and** `k3s.service`, then every value read back out of
+the kernel and asserted. Enabled for `[k3s_prod]`; **applies nothing until the operator runs it**.
+
+The investigation's main value is the negative results, all checked on the live nodes:
+
+- **`IOSchedulingClass=realtime` on `k3s.service` is a footgun, not a fix.** `mq-deadline` does
+  honour the priority class, so it looks correct — but ioprio is inherited across `fork` and kept
+  across `exec` (`block/blk-ioc.c` `__copy_io` copies `ioc->ioprio`), and **containerd is a child
+  of the k3s server process** (verified: containerd pid 84553, ppid 84333 = `k3s-server`; and
+  `ionice -c2 -n0 -- sh -c 'ionice -p $$; sh -c "ionice -p \$\$"'` reports best-effort prio 0 at
+  both levels). Realtime for k3s would be realtime for every container including Longhorn.
+- **`IOSchedulingPriority` (level within a class) is a no-op** — `mq-deadline` buckets by class only.
+- **`io.latency` is unavailable** — `CONFIG_BLK_CGROUP_IOLATENCY` is not built in Debian trixie's
+  7.1.8 kernel (only `IOCOST` is), and no `io.latency` exists under `/sys/fs/cgroup`.
+- **A bare `IOWeight=` drop-in is decoration.** systemd writes it to `io.weight` (blk-iocost —
+  compiled in but disabled; `io.cost.qos` is empty) and `io.bfq.weight` (BFQ — not loaded). Neither
+  reader exists on the stock nodes. And `IOWeight=1000` would map to `io.bfq.weight` ≈ 101 against
+  BFQ's unweighted default of 100 — hence 10000, and an asserted floor of 500.
+
+**What none of it fixes, stated so it is not forgotten:** etcd and Longhorn still share one ext4
+filesystem, and no cgroup or scheduler control arbitrates the **jbd2 journal** that etcd's
+`fdatasync` waits on and Longhorn's writes dirty. Software raises the load level at which this
+happens; it does not remove it.
+
+**Unproven.** The role fails loudly if its settings do not *land*; it cannot tell you they helped.
+Apply to `k3s-prod-3` first (WD Blue, PSI 1.29 — same code path, far lower stakes), watch
+`NodeIOPressureHigh` for a day, then node 1.
+
+### Doc correction found on the way
+
+`infra/ansible/README.md` still claimed `k3s-prod-2`/`-3` "stay commented out" of the inventory.
+They have been live in `[k3s_prod_secondary]` since 2026-09-03. Corrected, because that sentence is
+exactly the kind used to reason about blast radius: **`-e k3s_hosts=k3s_prod` targets three hosts,
+not one.** Confirmed by `--list-hosts` (dev default → 3 dev hosts, where the new role is a no-op;
+`-e k3s_hosts=k3s_prod` → 3 prod hosts; `--limit k3s-prod-3` → 1).
+
+### Still requires the operator
+
+1. **The hardware fix.** Replace node 1's C400, or add an M.2 per node and set
+   `node_baseline_etcd_source: device`. Everything above is a delay, not a repair.
+2. **Run `playbooks/etcd-io-priority.yml`** — node 3 first, `--limit`, `--list-hosts` confirmed.
+   Nothing was run against either cluster for this change.
+3. **Decide on `kubeEtcd` metrics**, so §2's exit condition can be measured with etcd's own fsync
+   histograms rather than inferred from node PSI.
+
+## 2026-09-07 — R-ENV-03's L0 check was RED on `main`, and the requirement's literal wording is why (branch `fix/r-env-03-overlay-selected-credentials`)
+
+`main`'s `conformance/tests/l0-static/prod-baremetal-not-dev-surface` failed 4 of 96 assertions.
+All four are the per-environment backup credentials merged in `e7c4a95`:
+
+```
+apps/wave-0/nextcloud-db-backup-credentials-prod.sops.yaml
+apps/wave-0/semaphore-db-backup-credentials-prod.sops.yaml
+platform/keycloak/keycloak-db-backup-credentials-prod.sops.yaml
+platform/velero/velero-cloud-prod.sops.yaml
+    ... is a prod-specific file inside the shared configuration
+```
+
+**The guard was a filename regex.** Any tracked file under `platform/ platform-config apps/
+catalog/ clusters/base/` whose name contained a delimited `prod` token failed, with no allowlist
+and no exception mechanism. Nothing about the four files' CONTENT was inspected.
+
+**Renaming them to dodge the regex was rejected** (operator, explicitly): the guard exists for a
+reason and a rename would leave the reason unserved while making the check lie. So the check was
+refined to test the harm instead of the spelling, and the requirement wording is escalated below.
+
+### Why these four files are compliant with R-ENV-02, and why the regex could not see it
+
+Backup credentials became per-environment because dev backs up to MinIO and prod to Cloudflare
+R2, and ONE shared Secret meant either environment's key rotation broke the other (worse for
+CNPG: `archive_mode=on` turns a 403 on WAL archive into a monotonically filling pgdata PVC).
+
+The mechanism is a single cluster-vars knob, `BACKUP_CREDENTIALS_SUFFIX` (base `""`, dev `""`,
+prod `"-prod"`). **Both Secret objects are applied to BOTH clusters** as base resources; the
+overlay changes only which one the shared consumer REFERENCES
+(`<name>${BACKUP_CREDENTIALS_SUFFIX}`). Every environment renders the identical manifests and the
+identical object set. That is exactly the "same manifests, overlay-scoped values" contract of
+R-ENV-02 — nothing is forked, and there is no prod-only content for anyone to develop against.
+The `-prod` in a filename is not a prod-only manifest; it is one half of an environment-selected
+pair, present everywhere.
+
+### What the check now asserts (committed on the branch; not a path allowlist)
+
+A file whose name carries the environment token is excused ONLY when the tree proves all of:
+
+- **(A)** it declares nothing but Secrets whose names end in the environment suffix — an overlay
+  can select which SECRET a shared manifest references and nothing else, so any other
+  prod-suffixed object in a shared path is prod-only content and still fails;
+- **(1)** its own directory's `kustomization.yaml` lists it in `resources` (so EVERY environment
+  applies it), and EVERY environment's value of the selector resolves to a Secret that some
+  resource of that same kustomization declares, in the same namespace — no environment is left
+  selecting an object that does not exist;
+- **(2)** nothing names the suffixed Secret — or the suffixed FILE — literally: every reference is
+  `<base-name>${VAR}`, and only the applying kustomization may name the file;
+- **(3)** that `VAR` is defined for `clusters/base` AND for every `clusters/<env>` overlay
+  (StrictPostBuildSubstitutions fails on an UNDEFINED variable, so an overlay that forgot it
+  would stop that cluster reconciling), and prod's value is the one that selects THIS file.
+
+References are read from PARSED YAML VALUES, never raw text — the mechanism is documented by name
+in comments beside the resources, and a name in a comment references nothing.
+
+Mutation-tested: eleven mutations, each restored afterwards, each of which must FAIL and does — a
+prod-only ConfigMap in a shared path, a prod-only Secret with no counterpart, a consumer
+hardcoding prod's Secret name, a kustomization naming prod's file from another directory, the
+knob missing from dev, the knob missing from base, prod's value drifted to a suffix nothing
+declares, the prod half dropped from `resources`, the base half deleted (with and without its
+`resources` entry), the halves split across namespaces, and one of two consumer references moved
+to a second knob. The legitimate four pass, with a `note:` per file saying why they were excused.
+
+### PROPOSED R-ENV-03 AMENDMENT — for the System Architect (spec repo is READ-ONLY here)
+
+**What the requirement says today** (`docs/00-vision-and-scope.md`, detail in `docs/02`): prod is
+a 3x mini-PC bare-metal k3s cluster with local storage and **"MUST NOT be an active development
+surface until the roadmap declares it ready"**; `docs/02` adds **"Never develop against prod.
+Prod hardware is a target, not a sandbox (R-ENV-03)."**
+
+**The problem with the literal reading.** Taken literally against the repository, "no prod-only
+content in the shared configuration" reads as "no artifact in a shared path may be specific to
+prod". That forbids the environment-selected PAIR, which is the very pattern R-ENV-02 prescribes
+for a value that must differ per environment while the manifests stay identical. The two
+requirements contradict each other on this case: R-ENV-02 says put the difference in an
+overlay-scoped value, and a Secret's difference cannot live in cluster-vars (it is ciphertext, per
+SOPS file, R-SEC-01), so it must live in a per-environment FILE that every environment applies.
+The requirement should forbid what is actually harmful — configuration only prod runs — not the
+appearance of an environment name in a path.
+
+**Proposed wording** (add as a clarifying clause to R-ENV-03 in `docs/02`, and mirror the phrase
+in `docs/00`):
+
+> Prod MUST NOT be an active development surface. Concretely: no artifact in the shared
+> configuration may be reachable by prod alone. An artifact whose NAME carries an environment

+
+That wording keeps the guard's teeth (an artifact only prod applies still fails), removes the
+false positive, and states the property the check now enforces so the test and the spec agree.
+
+**Related spec ask, same clause.** R-ENV-02 should say out loud that a per-environment SECRET is
+expressed as counterpart SOPS files applied everywhere plus a cluster-vars selector, because that
+is the one value class that cannot be expressed as a cluster-vars value itself. Without it, the
+next person hits the same contradiction.
+
+### How this reached `main` green — the gate hole, and whether the fix in flight closes it
+
+`ci/l0.sh` Stage 3b scopes the L0 conformance run to the TOUCHED requirement subset
+(`load_touched_requirements` -> `run.sh --requirements ...`). The delivery `e7c4a95` touched
+`apps/wave-0/`, `catalog/render.py`, `platform/keycloak/`, `platform/velero/` and declared no
+R-ID on a non-comment line, so the path map attributed R-GITOPS-02 / R-IDP-01..06 / R-STATE-03 —
+**and never R-ENV-03**. `prod-baremetal-not-dev-surface` was therefore FILTERED OUT of the run
+that gated the merge. The gate printed PASS having never executed the check that was already red.
+
+**Landing `fix/touched-requirements-fail-closed` would NOT have caught this.** Checked, not
+assumed: that branch's `ci/requirement-paths.map` classifies every path (so nothing is silently
+unmapped any more), but it attributes R-ENV-03 only to `infra/ansible/*` and `infra/tofu/*`.
+Replaying `e7c4a95`'s twelve paths through that map yields
+`R-GITOPS-01 R-GITOPS-02 R-IDP-01..06 R-PLAT-02 R-STATE-03` — still no R-ENV-03. Its `ci/l0.sh`
+change also leaves Stage 3b scoped (only the substitution stage stays unconditional). The
+fail-closed branch fixes the "unmapped path contributes nothing" hole; it does not fix this one.
+
+**Two things that would have caught it, for the operator/architect to choose between:**
+
+1. **Whole-repo L0 invariants should be unconditional.** `flux-postbuild-substitution`,
+   `keycloak-client-secret-reconciler` and `spec-immutability` already run as their own
+   unconditional stages for exactly this reason. `prod-baremetal-not-dev-surface`,
+   `no-plaintext-secrets` and `least-privilege-rbac` are the same shape — they assert over the
+   WHOLE tracked tree, so scoping them to a changed path is meaningless. Cheapest correct fix.
+2. **A changed test should attribute the requirements it declares.** `conformance/*` maps to
+   R-TEST-01..04 only, so editing `prod-baremetal-not-dev-surface/check.sh` does not select
+   R-ENV-03 — this very branch's gate run reports `touched requirements: R-ENV-02 R-TEST-01
+   R-TEST-02 R-TEST-03 R-TEST-04` and ran 2 of 12 L0 checks, NOT including the one it changed.
+   A changed `conformance/tests/<test>/` should contribute that test's own
+   `conformance.home.k3s/requirements` label.
+
+Both belong to `ci/`, so they are left to that branch rather than smuggled in here. The full L0
+layer was run unscoped on this branch to compensate: **12 offline checks, 11 PASS, 1 SKIP**
+(`placeholder-guard-coupling`, pre-existing), 0 FAIL.

+  # WHY READ-ONLY. Two independent reasons, either sufficient:
+  #   1. The old instance is STILL LIVE on it. The export is currently shared rw to 192.168.1.6 and

+  #      Nextcloud instances writing one instance's config directory, each with its own database and
+  #      therefore its own oc_filecache, is a corruption scenario with no clean recovery.
+  #   2. Nothing here needs writing. An archive is read.
+  # "Do not grant more than needed" therefore lands on `ro`. If the operator's intent is in fact a
+  # MIGRATION (read this data in, then decommission the old instance), that is a different and
+  # larger change than a mount, and it should be a deliberate one — flip `readOnly` and update the
+  # export at that point, not before. Enforced by the PV's nfs.readOnly, so it is a real `ro` mount.

+  # /media/movies (the library) and /media/downloads (the import source) UNDER THE SAME MOUNT.
+  #
+  # *** THE ROOT MOUNT IS THE POINT, NOT A CONVENIENCE. *** Radarr imports by HARDLINKING or
+  # atomically renaming a finished download into the library. Both are same-FILESYSTEM operations,
+  # and to the kernel "same filesystem" means SAME MOUNT. The layout on the host is:
+  #     /mnt/Storage/plex/movies/                      the library
+  #     /mnt/Storage/plex/downloads/complete/radarr/  where finished releases land
+  # — siblings under one dataset, so a hardlink between them is legal on the server. But mounting
+  # them as two subPath volumes (subPath: movies at /media/movies, subPath: downloads elsewhere) creates
+  # TWO mounts, and link() across mounts fails EXDEV no matter what the server thinks. Radarr then
+  # silently degrades to copy-then-delete: every import rewrites the whole file over NFS and the
+  # seeding copy is destroyed. Their smallest common ancestor IS the export root, so the root mount
+  # is the MINIMAL mount that preserves hardlinks — least privilege bounded below by a hard
+  # requirement, not a shortcut. (The cost is stated plainly: Radarr can also write /media/tv,
+  # which is sonarr's. Narrowing that would cost hardlinks, which is a worse trade.)
+  #
+  # *** /media, NOT /data — AND THAT IS NOT A STYLE CHOICE. *** The config PVC above renders at the
+  # renderer default /data/config. A media mount at /data would be mounted OVER it and MASK the
+  # config volume entirely; the pod would come up with its app database shadowed by an 8 T media
+  # tree. /media collides with nothing in a LinuxServer image and matches the path plex uses for
+  # the same export, so when qbittorrent is eventually given this mount too, the arrs and the
+  # download client will already agree on absolute paths — which is the other precondition for
+  # hardlinked imports (otherwise every import needs a Remote Path Mapping).
+  #
+  # SEPARATE LATENT BUG, NOT FIXED HERE (deliberately — it changes live on-disk state): /data/config
+  # is almost certainly the wrong place for this PVC in the first place. LinuxServer's arr images run
+  # with `-data=/config`, so the app writes /config — the container's EPHEMERAL layer — while the
+  # Longhorn PVC at /data/config sits unused. That is the EXACT failure plex's own mountPath comment
+  # documents having already been bitten by. Fixing it means starting from an empty config volume, so
+  # it belongs in its own change with the operator present.
+  #
+  # UID/GID — THE FAILURE THIS AVOIDS IS "MOUNTS FINE, CANNOT WRITE". The export is no_root_squash
+  # + sec=sys, so the client's numeric uid is passed through verbatim and the server's ownership is
+  # the whole story. The tree is 0755 owned 1000:3000 (some dirs 1000:1000), so ONLY uid 1000 can
+  # write it. LinuxServer images default to PUID/PGID 911 — which would mount cleanly and then fail
+  # every import with EACCES. The PUID/PGID set above make the process uid 1000, matching the owner.
+  #
+  # AND NOTE fsGroup CANNOT SUBSTITUTE FOR THAT. The in-tree NFS volume plugin performs no

+
+    WHY A PV AT ALL, RATHER THAN AN INLINE `nfs:` POD VOLUME
+    -------------------------------------------------------
+    An inline volume is fewer objects and it would work. It is rejected for four reasons, in
+    descending order of what they would cost to discover later:
+
+      1. RECLAIM POLICY. `persistentVolumeReclaimPolicy: Retain` is a declared, reviewable
+         property of a PV. There is no equivalent for an inline volume -- and the data behind
+         these mounts is 8.33 TiB of media and a 267 GiB archive that ALSO has live non-k3s
+         consumers. A statement in git that nothing in this cluster may reclaim it is worth an
+         object.
+      2. READ-ONLY LIVES IN ONE PLACE. `spec.nfs.readOnly: true` becomes a real `ro` mount option
+         for every pod that ever binds this volume. The same intent expressed on an inline volume
+         is one Deployment edit away from being dropped silently, with no diff anywhere near the
+         storage. (It is still a CLIENT-side guarantee -- the export cannot distinguish plex from
+         sonarr, since both may run on any node -- but it is one that lives in one reviewable
+         place.)
+      3. VISIBILITY. `kubectl get pv,pvc` is where an operator looks for "what external storage is
+         attached, and who holds it". An inline volume is invisible there, and invisible to
+         anything that reasons over PVCs.
+      4. IT IS THE CONTRACT THE REPO ALREADY HAS. Every other storage entry is a PVC; the
+         renderer, the Kyverno ServiceDefinition policy and the backup wiring all key on that. An
+         inline volume would be a second, parallel storage model inside the same renderer.
+
+    CROSS-NAMESPACE. A PV binds 1:1 to a PVC, so "plex, sonarr and radarr share one export" is NOT
+    one shared PV -- it is three PVs, one per namespace, each naming the same server+path. That is
+    the correct model rather than a workaround: the sharing happens on the NFS server, which is
+    built for concurrent clients, and each namespace keeps its own independently reviewable access
+    mode (plex ReadOnlyMany, the arrs ReadWriteMany). One shared PV would have forced a single
+    posture on all three.
+
+    BINDING IS PINNED FROM BOTH ENDS -- `claimRef` here and `volumeName` on the PVC. Either alone
+    leaves a race in which some other PVC of matching size and mode grabs the volume first;
+    together the binding is deterministic. `storageClassName: ""` (explicitly empty, NOT the `bulk`
+    StorageClass) is what tells the binder this volume is statically provisioned: it suppresses the
+    default-StorageClass annotation and guarantees no provisioner is ever asked to create anything.
+    It also sidesteps a trap -- a StorageClass's `provisioner` is IMMUTABLE, so re-pointing the
+    existing `bulk` class (whose stub names an NFS CSI driver that is not installed) at this data
+    would make Flux fail forever on that one object.

+  # THE MEDIA TREE (docs/04 bulk tier) — ONE read-WRITE mount of the export ROOT at /media, giving
+  # /media/tv (the library) and /media/downloads (the import source) UNDER THE SAME MOUNT.
+  #
+  # *** THE ROOT MOUNT IS THE POINT, NOT A CONVENIENCE. *** Sonarr imports by HARDLINKING or
+  # atomically renaming a finished download into the library. Both are same-FILESYSTEM operations,
+  # and to the kernel "same filesystem" means SAME MOUNT. The layout on the host is:
+  #     /mnt/Storage/plex/tv/                      the library
+  #     /mnt/Storage/plex/downloads/complete/tv-sonarr/  where finished releases land
+  # — siblings under one dataset, so a hardlink between them is legal on the server. But mounting
+  # them as two subPath volumes (subPath: tv at /media/tv, subPath: downloads elsewhere) creates
+  # TWO mounts, and link() across mounts fails EXDEV no matter what the server thinks. Sonarr then
+  # silently degrades to copy-then-delete: every import rewrites the whole file over NFS and the
+  # seeding copy is destroyed. Their smallest common ancestor IS the export root, so the root mount
+  # is the MINIMAL mount that preserves hardlinks — least privilege bounded below by a hard
+  # requirement, not a shortcut. (The cost is stated plainly: Sonarr can also write /media/movies,
+  # which is radarr's. Narrowing that would cost hardlinks, which is a worse trade.)
+  #
+  # *** /media, NOT /data — AND THAT IS NOT A STYLE CHOICE. *** The config PVC above renders at the
+  # renderer default /data/config. A media mount at /data would be mounted OVER it and MASK the
+  # config volume entirely; the pod would come up with its app database shadowed by an 8 T media
+  # tree. /media collides with nothing in a LinuxServer image and matches the path plex uses for
+  # the same export, so when qbittorrent is eventually given this mount too, the arrs and the
+  # download client will already agree on absolute paths — which is the other precondition for
+  # hardlinked imports (otherwise every import needs a Remote Path Mapping).
+  #
+  # SEPARATE LATENT BUG, NOT FIXED HERE (deliberately — it changes live on-disk state): /data/config
+  # is almost certainly the wrong place for this PVC in the first place. LinuxServer's arr images run
+  # with `-data=/config`, so the app writes /config — the container's EPHEMERAL layer — while the
+  # Longhorn PVC at /data/config sits unused. That is the EXACT failure plex's own mountPath comment
+  # documents having already been bitten by. Fixing it means starting from an empty config volume, so
+  # it belongs in its own change with the operator present.
+  #
+  # UID/GID — THE FAILURE THIS AVOIDS IS "MOUNTS FINE, CANNOT WRITE". The export is no_root_squash
+  # + sec=sys, so the client's numeric uid is passed through verbatim and the server's ownership is
+  # the whole story. The tree is 0755 owned 1000:3000 (some dirs 1000:1000), so ONLY uid 1000 can
+  # write it. LinuxServer images default to PUID/PGID 911 — which would mount cleanly and then fail
+  # every import with EACCES. The PUID/PGID set above make the process uid 1000, matching the owner.
+  #
+  # AND NOTE fsGroup CANNOT SUBSTITUTE FOR THAT. The in-tree NFS volume plugin performs no
+  # ownership management, so podSecurityContext.fsGroup is a NO-OP on this volume — it is not the
+  # lever here, and reaching for it is how this failure normally gets misdiagnosed. The fsGroup

+### Second-order CRDs need a THIRD pass (`platform-config-cdi`, added 2026-09-05)
+
+The controllers/configs split (`platform` → `platform-config`) assumes a CRD is registered by the
+controller **install**. CDI breaks that: `cdi-operator.yaml` registers only `cdis.cdi.kubevirt.io`,
+and cdi-operator creates `storageprofiles` / `datavolumes` / `datasources` **only after it has
+reconciled the `CDI` CR**. Since kustomize-controller server-side **dry-runs every object in a pass
+before applying any of them**, having the `CDI` CR and the CDI `StorageProfile`s in one pass was a
+**deadlock, not a race**: unknown kind → pass aborts → CR never applied → CRD never created →
+`platform-config` can never converge → every tier below it blocked. Invisible on dev (its CDI CRDs
+have existed for months); it cost 12h on prod's cold start.
+
+So there is a third tier, `platform-config-cdi` (`./platform-config-cdi`, `dependsOn:
+platform-config`), and a rule:
+
+> A CR belongs in `platform-config-cdi`, not `platform-config`, when the CRD it needs is created by a
+> **controller at runtime** rather than by a manifest in git.
+
+`apps-vms` `dependsOn` it as well as `platform-config`, because CDI reads
+`StorageProfile/longhorn-vm` at DataVolume **provisioning** time — a VM disk provisioned before that
+profile exists is stamped RWO/Filesystem and is permanently not live-migratable.

+  # Nothing about the object layout was per-environment before this: Velero's bucket was the
+  # hardcoded literal `velero` with no prefix, and every CNPG Cluster used the hardcoded
+  # `s3://cnpg` with barman's `serverName` defaulting to the CLUSTER NAME — and BOTH environments
+  # have a keycloak-db, a nextcloud-db and a semaphore-db. Point two clusters at one bucket under
+  # that layout and:
+  #   (a) each cluster's Velero ADOPTS the other's backups and TTL-DELETES them on retention; and
+  #   (b) two different Postgres servers stream WAL into ONE Barman prefix, which does not merely
+  #       mix files — it CORRUPTS THE CHAIN and destroys PITR for both. That is the worse half:
+  #       dev's DR restore is PROVEN (R-STATE-03) and this would silently un-prove it.
+  #
+  # WHY THERE IS NO SINGLE `S3_BACKUP_BUCKET`. The two consumers take differently-SHAPED values:
+  # the Velero chart wants `bucket` and `prefix` as separate fields, while CNPG's
+  # barmanObjectStore.destinationPath is ONE full s3:// URL whose first path segment IS the bucket.
+  # CNPG's bucket therefore already lives inside CNPG_BACKUP_PATH; adding a second knob that had to
+  # hold the same bucket name a second time would be a rotation waiting to drift — the exact class
+  # of duplication this repo has been bitten by. Three knobs, each shaped for its own consumer, and
+  # no two of them can contradict each other.
+  #
+  # BASE = DEV'S LIVE LAYOUT, BYTE-FOR-BYTE, AND MUST STAY THAT WAY. Dev's existing backups are at
+  # `s3://velero/` (bucket root, no prefix) and `s3://cnpg/<clusterName>/` on that MinIO. Giving dev
+  # a prefix, or renaming its buckets, would ORPHAN the very backups its proven restore depends on —
+  # the same reason dev's EXTERNALDNS_TXT_OWNER_ID stays `default` and its LONGHORN_DATA_PATH stays
+  # /var/lib/longhorn. Verified: with an EMPTY prefix the Velero chart omits `objectStorage.prefix`
+  # from the rendered BackupStorageLocation entirely (helm template, chart 12.1.0), so dev's live
+  # BSL is unchanged by this parameterization rather than merely equivalent to it.
+  #
+  # PROD, which has no history to preserve, gets ONE bucket with TWO disjoint top-level prefixes:

+  #
+  # The operator created exactly one R2 bucket, so velero-vs-barman separation has to come from the
+  # prefix rather than the bucket. The BUCKET ROOT IS DELIBERATELY LEFT EMPTY: if a prefix ever
+  # renders wrong, its objects land somewhere obviously bogus instead of silently colliding with a

+  # WHICH CREDENTIAL SECRET THE BACKUP CONSUMERS READ (added 2026-09-07 — the per-env credential split)
+  # ------------------------------------------------------------------------------------------------
+  # The three knobs above say WHERE the backups go. This one says WHICH KEY signs the requests, and
+  # it exists because the endpoint moved per-environment while the credential did not.
+  #
+  # THE BUG IT FIXES. The four backup-credential Secrets — velero-cloud.sops.yaml and the three
+  # <db>-backup-credentials.sops.yaml — are SHARED BASE manifests: platform/ and apps/ are rendered
+  # by the same Flux tiers on both clusters, and cluster-vars substitution is the ONLY thing that
+  # differs (R-ENV-02). So writing prod's R2 token into those four files did not GIVE prod a
+  # credential, it REPLACED DEV'S: dev's Velero and all three dev CNPG Clusters would have started
+  # signing MinIO requests with an R2 key id. For Velero that is a broken BSL; for CNPG it is worse,
+  # because `archive_mode=on` means Postgres REFUSES TO RECYCLE a WAL segment it could not archive,
+  # so a 403 loop is a monotonically filling pgdata PVC ending in a PANIC — the same failure prod
+  # spent its whole bring-up in with a placeholder endpoint. One shared Secret also means rotating
+  # either environment's key silently breaks the other; that is the structural reason for the split,
+  # independent of dev's eventual decommission.
+  #
+  # THE MECHANISM. Each credential is now TWO Secret objects, both applied to BOTH clusters (they are
+  # base resources; nothing here forks a manifest per environment). The consumer names one:
+  #
+  #     velero:   credentials.existingSecret: velero-cloud-credentials${BACKUP_CREDENTIALS_SUFFIX}
+  #     CNPG:     s3Credentials.*.name:  <db>-backup-credentials${BACKUP_CREDENTIALS_SUFFIX}
+  #
+  # ONE knob, not four, ON PURPOSE. Four independent secret-name knobs could be updated three-
+  # quarters of the way, leaving one consumer pointed at the OTHER environment's key with nothing
+  # rendering wrong — and StrictPostBuildSubstitutions cannot catch that, because it only fails on an
+  # UNDEFINED variable, never on a defined-but-stale one. With a single suffix the four move together
+  # or not at all. The cost is that the rendered Secret name is not greppable from the consumer; the
+  # names are spelled out in full in each kustomization.yaml beside the resources.
+  #
+  # THE BASE DEFAULT IS THE EMPTY STRING, AND THAT IS LOAD-BEARING. It renders the UNSUFFIXED names,
+  # which are the objects that already exist and that the live dev cluster is running. A default
+  # naming a Secret that does not exist would be worse than the shared-Secret state it replaces:
+  # Velero's pod would sit in ContainerCreating forever on a missing `existingSecret` volume, and a
+  # CNPG Cluster whose s3Credentials Secret is absent stops archiving WAL — i.e. the disk-full clock
+  # again — so an unresolvable default breaks the referencing cluster HARDER than a wrong key does.
+  # Empty is also the value dev must carry, so base and dev agree, exactly like VELERO_BACKUP_PREFIX.
+  #
+  # An EMPTY VALUE IS SAFE UNDER StrictPostBuildSubstitutions: strict mode fails on a variable that is

+# Flux Kustomization: SECOND-ORDER CDI CONFIGS — reconciles ./platform-config-cdi.
+# Serves R-GITOPS-01 (all desired state in git, reconciled by Flux) and R-ENV-02.
+#
+# WHY THIS TIER EXISTS — the durable fix for the 2026-09-05 prod CDI DEADLOCK
+#
+# `platform-config` applied the `CDI` CR and the CDI `StorageProfile`s in the SAME pass.
+# kustomize-controller server-side DRY-RUNS EVERY object before applying ANY of them, and
+# `storageprofiles.cdi.kubevirt.io` does not exist until cdi-operator has reconciled that `CDI` CR.
+# So the unknown kind aborted the whole tier → the CR was never applied → the CRD was never created →
+# platform-config could NEVER converge and every tier below it stayed blocked. Not a race: a
+# deadlock. cdi-operator was Available for 12h on prod with no CR. Invisible on dev (its CDI CRDs
+# have existed for months), FATAL on any cold cluster. See DECISIONS-LOG 2026-09-05.
+#
+# `bootstrap/standup.sh crds` pre-applies the `CDI` CR to break it by hand. That is a WORKAROUND and
+# stays as belt-and-braces for clusters already wedged; THIS Kustomization is the fix that makes the
+# graph order itself, so a cold cluster needs no human in the loop.
+#
+# THE ORDERING GUARANTEE, precisely: `dependsOn` is REVISION-gated, not merely Ready-gated (verified
+# against kustomize-controller v1.4.0 `kustomization_controller.go :: checkDependencies`, our
+# version): sharing a GitRepository with the dependency, this Kustomization cannot reconcile revision
+# N until `platform-config` has APPLIED revision N — and, because platform-config runs `wait: true`,
+# not until the `CDI` CR it applied is HEALTHY. cdi-operator creates the remaining CDI CRDs as part of
+# reaching that state, so by the time this tier's first dry-run runs, `StorageProfile` is a known
+# kind. One edge, no pre-apply.
+#
+# WHY NOT just move the CDI CR earlier, into `platform`? Because `platform` is the tier the CNI gates
+# and everything else waits on: putting CDI's health on that critical path is the mistake the
+# oauth2-proxy/headlamp splits were made to undo. The CR is correctly a platform-config CR; it is the
+# StorageProfiles that were in the wrong pass.

+  # If a resource that CAN be unhealthy is ever added to ./platform-config-cdi, re-derive this:
+  # `apps-vms` waits on it.
+  #
+  # WHAT IT DOES NOT PROVE (honest gap): CDI reads the profile's **status**, not its spec, when it
+  # provisions a claim (status.claimPropertySets / status.cloneStrategy), and CDI's
+  # storageprofile-controller computes that status from our spec override plus inference. So Ready
+  # here means "the spec override is accepted by the API server", not "CDI has folded it into

+  # dual-ownership fight — the objects are pruned before they are re-applied under this tier's
+  # `kustomize.toolkit.fluxcd.io/name=platform-config-cdi` label).
+  #
+  # Why that is acceptable here — and it is NOT the platform/cilium case:
+  #   * Neither object is the sole (or any) declarer of a shared object. No Namespace, no ConfigMap,
+  #     nothing else in the repo declares a StorageProfile. The stale set is exactly two
+  #     cluster-scoped CDI CRs.
+  #   * The objects do not actually go missing: CDI's storageprofile-controller creates a
+  #     StorageProfile per StorageClass and recreates a deleted one, with an EMPTY `.spec` and
+  #     inferred `.status`. So the transient is "our .spec overrides are absent", not "the object is
+  #     absent".
+  #   * A StorageProfile is read at DataVolume/PVC PROVISIONING and CLONE time only. Existing PVCs,
+  #     existing DataVolumes and running VMs do not consult it again, so nothing already provisioned
+  #     is disturbed and no data path is touched.
+  #   * The only exposure is a DataVolume/clone STARTED inside the window: it would clone by `copy`
+  #     instead of `snapshot`, and on `longhorn-vm` be stamped RWO/Filesystem instead of RWX/Block —
+  #     permanently non-live-migratable for that disk. Flux cannot cause that, because `apps-vms` now
+  #     dependsOn THIS tier (clusters/base/apps-vms.yaml), so no Flux-managed DataVolume can be
+  #     created while the overrides are absent. A human running `virtctl`/`kubectl` in that minute
+  #     could.
+  #
+  # PRECONDITION THE OPERATOR MUST CHECK, because it is what bounds the window: the recreate cannot
+  # happen until `platform-config` is Ready, and platform-config runs `wait: true` over the whole
+  # config tier (ClusterIssuers, wildcard Certificate, Gateway, Keycloak, CNPG, KubeVirt, CDI…). On a
+  # healthy cluster that is seconds and the window is ~30-60s (kustomize-controller's
+  # --requeue-dependency default is 30s). If platform-config is NOT Ready when this merges, the
+  # StorageProfiles are pruned and stay at CDI defaults until it recovers. So:
+  #   `flux get kustomization platform-config` must be Ready BEFORE merging.
+  # If it is not, do the two-step the cilium move used instead: merge with `platform-config.prune`
+  # temporarily set to `false` (the objects are then dropped from its inventory but NOT deleted, and
+  # this tier ADOPTS them with zero window), verify the ownership label transferred, then restore
+  # `prune: true` in a second commit.

+  #   operator's workstation, Gitea 1.22.6, listening on 192.168.2.132:3000. All three prod nodes
+  #   reach it DIRECTLY on the LAN: no libvirt NAT hop (that network is retired) and no firewall
+  #   change was needed. This is the same "local bootstrap source" pattern dev itself used before
+  #   its Phase-6 cutover (docs/05 "Source-of-truth").
+  #
+  # PLAIN HTTP, AND WHY THAT IS ACCEPTED HERE: the bootstrap Gitea has no TLS, so there is no cert
+  # for Flux to trust and no caCertSecretRef to wire. Traffic is LAN-local between prod nodes and
+  # the workstation, the repo carries NO plaintext secrets (everything sensitive is SOPS-encrypted,
+  # .sops.yaml), and the window is the bring-up only. Do NOT extend this posture past cutover.
+  #
+  # NO secretRef, DELIBERATELY: the repo is PUBLIC on the bootstrap Gitea, so anonymous clone
+  # works and Flux needs no git credentials. VERIFIED 2026-09-04 by unauthenticated request:
+  #   curl http://192.168.2.132:3000/api/v1/repos/Home-Network/home-network-k3s-impl -> "private":false
+  #   git ls-remote http://192.168.2.132:3000/Home-Network/home-network-k3s-impl.git  -> refs/heads/main
+  # If the GitRepository ever reports an auth failure that looks like a network problem, RE-CHECK
+  # THAT FIRST: a private repo here fails exactly that way.
+  #
+  # *** CUTOVER — the exit condition, mirroring dev's Phase-6 cutover (docs/05) ***
+  #   WHEN: Gitea runs on prod (reconciled in-cluster) and answers gitea.home.keithjackson.dev
+  #         through prod's own Gateway VIP with a publicly-trusted cert.
+  #   DO:   1. push/mirror this repo into the prod in-cluster Gitea;
+  #         2. change the url below to
+  #            https://gitea.home.keithjackson.dev/Home-Network/home-network-k3s-impl.git
+  #            and DELETE this whole TEMPORARY block (dev's equivalent stanza, ~15 lines above in
+  #            clusters/dev/kustomization.yaml, is what "done" looks like);
+  #         3. confirm `flux get sources git -n flux-system` reconciles the new revision;
+  #         4. only THEN stop the workstation container. Keep it stopped-not-deleted as recovery,
+  #            exactly as dev retained its bootstrap Gitea.
+  #   UNTIL THEN: prod's reconciliation depends on a container on a workstation that may be
+  #   powered off. Flux keeps the last-reconciled state running, but NO new revision lands while
+  #   it is down. Tracked as an open blocker in infra/PROD-PROVISIONING.md §7.
   #
   # The BRANCH below is settled and correct: prod tracks `main`, the same branch as dev.
   # CONSEQUENCE, recorded deliberately: 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.
+  # NOTE for bring-up: bootstrap-gitea.sh pushes the operator's CURRENT HEAD to the bootstrap
+  # Gitea's `main`, whatever branch that is. Before bootstrapping prod, confirm that remote `main`
+  # is the revision you intend prod to run (`git ls-remote` above, against local `main`).

+# WHY THIS IS NOT A WHOLE-FILE `"TODO" in text`
+# ---------------------------------------------------
+# It used to be, and that mis-reported a SAFETY-CRITICAL requirement. A test whose SUBJECT
+# is placeholder detection has to name the idioms it hunts for:
+# `l0-static/placeholder-guard-coupling/check.sh` carries
+# `SEED = ["TBD", "TODO", "FIXME", "PLACEHOLDER", ...]` — its detection vocabulary, as data.
+# A whole-file substring test read that as the test declaring itself unfinished, classified
+# a 32-assertion executable check as a scaffold, raised a permanent `--strict` annotation
+# conflict, and (because the same file is tagged R-STATE-03) reported R-STATE-03 as
+# `exec=1 scaffold=1`. A previous engineer worked around it by rewording prose.
+#
+# The rule below is derived from the corpus (43 tests), not invented. Every genuine
+# scaffold in this tree — `l2-behavioral/onboarding-completeness`, `l3-fault-injection/
+# alerting`, `l3-fault-injection/gitops-drift`, and no others — declares itself in BOTH of
+# two structural positions, and no executable test does either:
+#
+#   1. a `# STATUS: ... scaffold` line in the file's documentation header. This is the
+#      repo's DEDICATED declaration slot (tests/README.md): 3 of 43 tests say
+#      `STATUS: scaffold` and they are exactly the three scaffolds; 19 others declare
+#      `STATUS: EXECUTABLE` / `IMPLEMENTED` / `RUNNABLE`; the rest declare nothing.
+#   2. a TODO/FIXME marker in the BODY that CARRIES A MESSAGE — `echo "TODO: assert PVC
+#      bound ..."`, `TODO(T-4.1): hermetic SMTP capture sink`. A marker that carries a
+#      message is a note about work that is missing. A marker that is the ENTIRE content of
+#      a quoted literal (`"TODO",` in a vocabulary list) carries no message: it is the
+#      marker as a *datum*, which is what a placeholder DETECTOR necessarily contains.
+#
+# Both are still evaluated over the body of `chainsaw-test.yaml` AND of any
+# `render-check.sh` / `check.sh`, and either one still OUTRANKS an
+# `executable: "true"` annotation (see classify_test) — the invariant that an annotation
+# must never outrank the body is unchanged. Ambiguity still only ever DOWNGRADES: an
+# unrecognised marker shape, a marker in body code outside a quoted literal, or a marker
+# carrying any trailing text all classify as scaffold.
+#
+# KNOWN, ACCEPTED IMPRECISION (stated rather than hidden): a test that embeds a marker with
+# text attached but as data — e.g. `re.compile(r"TODO|FIXME")`, or a single string holding
+# several idioms — is still called a scaffold. That is the conservative direction, and the
+# author's remedy is the same structural discipline the corpus already uses: keep each
+# idiom a standalone literal in a list.
+
+# Vocabulary: only the idioms that DECLARE unfinished work. Deliberately excludes `TBD`,
+# `PLACEHOLDER`, `XXX`, `REPLACE-ME` — tests in this tree legitimately carry those in
+# executable code as data (`l0-static/egress-paths-selected-by-rules/check.sh` compares
+# authored values against `"TBD"`; `l0-static/no-plaintext-secrets/check.sh` matches
+# `placeholder.*`), and none of them is used here to mark a placeholder body.

+### How a scaffold declares itself (and how `status.py` tells one from a verifier)
 
 Scaffolds in this tree carry `TODO(T-x.y)` markers where a fixture/assertion lands as a
-later roadmap phase delivers the capability under test. `lib/status.py` treats such a
-marker — in the `chainsaw-test.yaml`, in `render-check.sh`, or in `check.sh` — as
-outranking any `conformance.home.k3s/executable: "true"` annotation, so a placeholder body
-can never be reported as an executable test.
+later roadmap phase delivers the capability under test. `lib/status.py` classifies each
+test EXECUTABLE or SCAFFOLD from the test's own files — `chainsaw-test.yaml`,
+`render-check.sh`, `check.sh` — and either signal below **outranks**
+`conformance.home.k3s/executable: "true"`, so a placeholder body can never be reported as
+an executable test. Declare a scaffold in **both** positions:
+
+1. **`# STATUS: scaffold — <what is missing>`** in the file's header comment block. The
+   declared state must be the first token after `STATUS:` (executable tests say
+   `# STATUS: EXECUTABLE` / `IMPLEMENTED` / `RUNNABLE`).
+2. **A `TODO`/`FIXME` marker carrying a message, in the body** — the file from its first
+   non-comment line onward. `echo "TODO(T-4.2): inject a fault to fire a rule"`,
+   or an inline comment on a missing fixture:
+   `file: fixtures/smtp-sink.yaml   # TODO(T-4.1): hermetic SMTP capture sink`.
+
+What is **not** a scaffold marker, and why the distinction is load-bearing: a marker
+mentioned in the **header prose** (the Given/When/Then and the mandatory "what this does
+NOT prove" list), and a marker that is the **entire content of a quoted literal** — a
+placeholder *detector*'s own vocabulary, e.g. `SEED = ["TBD", "TODO", "FIXME", ...]` in
+`l0-static/placeholder-guard-coupling/check.sh`. A whole-file `"TODO" in text` test used to
+classify that 32-assertion check as a scaffold and, through it, report the safety-critical
+R-STATE-03 as `exec=1 scaffold=1`. If your check must hold a marker as data, keep each
+idiom a **standalone quoted literal in a list**; a marker with text attached (a regex
+alternation, several idioms in one string) still classifies as a scaffold, because
+ambiguity here only ever downgrades.

+#
+# HOW THIS AVOIDS BEING A TAUTOLOGY (the whole design question for a meta-requirement)
+# -----------------------------------------------------------------------------------
+# "A test exists for R-NET-01, therefore isolation is auditable" would pass in any suite that
+# compiles and would keep passing while every proof rotted into a scaffold. Four distinct
+# failure modes are asserted instead, each by DRIVING the real machinery:
+#   (a) each of the five proofs has an EXECUTABLE test — not a placeholder scaffold — at the layer
+#       the spec's own words require (fault injection / a DR drill => L3), taken from
+#       lib/status.py's own verdict so this check cannot disagree with the status report;
+#   (b) the proofs are PRODUCIBLE by the documented command: `run.sh --requirements <the five>`
+#       must resolve to real test dirs AND pass the merge gate's coverage assertion;
+#   (c) each Chainsaw-layer proof declares a PASS SENTINEL that lib/record_run.py can
+#       attribute — a proof that passes but records nothing leaves the operator with a green
+#       terminal and no evidence;
+#   (d) the evidence chain REFUSES FORGERIES: this check mounts two of its own against the
+#       real tools — a green JUnit for a real proof test whose log holds only that test's SKIP
+#       token, and a ledger row claiming `proven` at the repository's ROOT commit — and
+#       requires record_run.py to report not-proven and status.py to report `stale-proof`. It
+#       also drives `record_run.py --selftest` and `status.py --selftest`, which NOTHING in
+#       ci/ or run.sh ran before this test existed.
+# The five proofs are not hand-listed where the spec can be read: when the read-only spec repo
+# is mounted, docs/07's bullet labels are parsed and must match this check's mapping exactly,
+# so a sixth proof added to the spec fails here instead of being silently unverified.
+#
+# WHY L0: every clause is a property of the repository and its own tooling, needs no cluster,
+# and belongs in the merge gate — an audit chain is worth having only if it is intact BEFORE
+# anyone needs it.
+#
+# GIVEN the repository as git tracks it (plus the read-only spec repo when mounted),
+# WHEN  lib/status.py, lib/common.sh's requirement resolver, run.sh's coverage gate,
+#       lib/record_run.py's sentinel parser and both evidence tools' self-tests are DRIVEN,
+#       and two synthetic forgeries are presented to them,
+# THEN  each of docs/07's five proofs maps to an executable test at the required layer, the
+#       documented one-command invocation selects and asserts them, each is capturable as a
+#       ledger row, and neither a self-skip nor a stale row can be recorded as proof.
+#
+# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git tree + the harness's
+# own stdlib tooling; no cluster, no network); conformance/run.sh --layer l0 and ci/l0.sh run
+# it directly, and this Chainsaw Test wraps the SAME script.
+#
+# WHAT THIS TEST FIXED WHILE BEING WRITTEN (recorded, not hidden): three of the tests that ARE
+# the automated half of docs/07's isolation and TLS proofs — l2-behavioral/default-deny,
+# l2-behavioral/trusted-tls and l2-behavioral/gateway-ingress-reachable — declared NO pass
+# sentinel, so lib/record_run.py could never record them as proven and those two audit proofs
+# were structurally unrecordable. Each now ends with a proof-of-pass sentinel step. The
+# assertion here was NOT relaxed to accommodate them (R-TEST-06).
+#
+# KNOWN, DELIBERATE GAPS (enumerated in check.sh's header; this test claims none of them):
+#   * That the five proofs PASS. This asserts they are present, strong, runnable by one
+#     command, capturable, and that the chain refuses forgeries — not that isolation holds
+#     today (R-NET-01's test) or that the restore works (R-STATE-03's).
+#   * HUBBLE. docs/07 names Hubble flow logs as part of the isolation proof; no test in this
+#     suite queries Hubble. Only the denied-probe half is automated — a real, named gap.
+#   * LEDGER COMPLETENESS OVER TIME. Nothing offline can prove a row was never removed; that
+#     would need signed history.

+#
+# HOW A META-REQUIREMENT IS TESTED WITHOUT BECOMING A TAUTOLOGY
+# ------------------------------------------------------------
+# The trap is obvious and this check is built to avoid it: "a test exists for R-NET-01,
+# therefore isolation is auditable" is true of any suite that compiles, proves nothing, and
+# would keep passing while every proof rotted into a scaffold. Four separate failure modes
+# have to be caught for "an operator can PROVE it" to mean anything, and each one is asserted
+# by DRIVING the real machinery rather than by reading files:
+#
+#   (a) THE PROOF EXISTS, AT THE RIGHT STRENGTH. Each of the five named proofs maps to a
+#       requirement that must have an EXECUTABLE verifying test — not a placeholder scaffold — and,
+#       where the spec's own words name fault injection ("with VPN down"; "a DR drill"), an
+#       executable L3 test specifically. Executable-vs-scaffold is not re-derived here: this
+#       check RUNS lib/status.py and reads its verdict, so it cannot disagree with the
+#       repository's own status report.
+#   (b) THE PROOF IS PRODUCIBLE ON DEMAND, BY THE DOCUMENTED COMMAND. `run.sh
+#       --requirements <the five IDs>` must resolve to a non-empty test set and must ASSERT
+#       their coverage (that flag is the merge gate's own path: it passes --require to
+#       coverage.py). This check drives run.sh itself, so if the resolver, the labels or the
+#       gate wiring break, R-SEC-03 fails.
+#   (c) THE PROOF IS CAPTURABLE. A test that passes but records nothing leaves an operator
+#       with a green terminal and no evidence. For each Chainsaw-layer proof, the test must
+#       declare a PASS SENTINEL that lib/record_run.py can actually attribute — computed with
+#       record_run.py's OWN parser, so deleting a test's sentinel makes this check fail
+#       instead of silently making the requirement unprovable.
+#   (d) THE EVIDENCE CANNOT BE FORGED, AND IS NOT HONOURED WHEN STALE. This is the clause
+#       that makes the check bite. Two INDEPENDENT forgery attempts are mounted against the
+#       real tools, in a throwaway directory:
+#         * a Chainsaw run in which the JUnit says a real proof test PASSED while the run log
+#           carries only that test's SKIP token — the exact shape of a self-skipping L2/L3
+#           test. record_run.py must refuse to call it `proven`.
+#         * a ledger row claiming `proven` at a commit that PREDATES the requirement's
+#           implementing code — status.py must degrade it to `stale-proof`, never green.
+#       Both tools' own built-in self-tests (`--selftest`) are also driven, because nothing
+#       in ci/ or run.sh runs them today: the guards that keep a skip from becoming a proof
+#       were themselves unexercised in the merge gate until this check.
+#
+#   The FIVE PROOFS ARE NOT HAND-LISTED where the spec can be read: when the read-only spec
+#   repo is mounted, the bullet labels are parsed out of docs/07 and must match this check's
+#   mapping EXACTLY. Add a sixth proof to the spec and this check fails as unmapped rather
+#   than quietly ignoring it.
+#
+# WHY L0: every clause above is a property of the repository and its own tooling, provable
+# offline, and it belongs in the merge gate — the point of an audit chain is that it is intact
+# BEFORE anyone needs it. Nothing here needs a cluster, and nothing here would be more true
+# with one.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this check as claiming them):
+#   - THAT THE FIVE PROOFS PASS. This asserts the proofs are present, strong, runnable by one
+#     documented command, capturable as evidence, and that the evidence chain refuses
+#     forgeries. Whether isolation actually holds today is R-NET-01's test; whether the DR
+#     restore works is R-STATE-03's. R-SEC-03 is about the operator's ABILITY to produce the
+#     proof, which is what is asserted.
+#   - HUBBLE. docs/07 names "Hubble flow logs" as part of the isolation proof. No test in this
+#     suite queries Hubble, and this check does not pretend otherwise: it asserts the
+#     denied-probe half, which is the half that is automated. The Hubble half remains an
+#     operator-interactive capability — a real, named gap in R-SEC-03's coverage.
+#   - THE OPERATOR-FACING NARRATIVE. That a human can find and read the evidence (the status
+#     report's prose, the ledger's provenance fields) is a usability property, not a testable
+#     one.
+#   - LEDGER COMPLETENESS OVER TIME. The ledger is append-only by convention and by review;
+#     nothing here can prove a row was never removed from it (that would need signed history).
+#   - THAT THE PROOFS COVER "ALL THE ABOVE PROPERTIES". R-SEC-03's own wording is broader than
+#     the five bullets docs/07 enumerates. The five are what the spec made concrete and are
+#     what is asserted; suite-wide coverage of every requirement is R-TEST-01/04's claim,

+# L0 STATIC — the bulk tier's capacity strategy is DISTINCT from the replicated tier's
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# THE BUG CLASS THIS CLOSES. The `bulk` StorageClass existed from Phase 0 as a stub:
+# `provisioner: nfs.csi.k8s.io`, `server: REPLACE-ME`, `share: REPLACE-ME`, TODO(OQ-2).
+# Four ServiceDefinitions carried a comment promising to attach their media once OQ-2 was
+# resolved, and the ONLY thing keeping a multi-terabyte library off the 3-replica
+# `longhorn` class was those four comments. A bulk volume that lands on the replicated
+# tier does not fail loudly — Longhorn accepts the PVC and starts replicating 3x of data
+# three mini-PCs cannot hold. R-STATE-04 is precisely that the two tiers are distinct, so
+# the distinctness is asserted rather than reviewed.
+#
+# It also pins the four decisions that make the STATIC form of this tier safe, each with a
+# plausible "simplification" that breaks something silently: `Retain` (bulk data pre-exists
+# the cluster and has consumers outside it, so anything else makes `delete pvc` a data-loss
+# operation); NO dynamic provisioning (a dynamic bulk class hands out a FRESH EMPTY
+# directory that mounts and Binds perfectly while the real 8 TiB is never attached — the
+# most deceptive failure available here); `hard` not `soft` (a soft mount hands a server
+# hiccup to the app as a short read, which for a media library is silent corruption); and
+# NFSv4 (mount and lock in-protocol ⇒ ONE reachable port, tcp/2049, which is what the
+# operator must open in pfSense for prod to reach this server at all).
+#
+# AND the EXDEV trap, which is not about storage. Sonarr/Radarr import by hardlinking or
+# atomically renaming, both same-filesystem operations, and to the kernel "same filesystem"
+# means SAME MOUNT. Splitting one export into two subPath mounts looks TIGHTER and breaks
+# link() with EXDEV; the arrs then degrade to copy-then-delete, rewriting every import over
+# NFS and destroying the seeding copy. It surfaces weeks later as "imports are slow and my
+# ratio is gone". A reviewer cannot see that; this check can.
+#
+# GIVEN the repository as authored,
+# WHEN  every `class: bulk` storage entry in catalog/ is compared against the objects the
+#       COMMITTED apps/ goldens carry for it (what Flux reconciles — deliberately not the
+#       renderer, which would only prove it agrees with itself),
+# THEN  (1) no bulk volume is on a Longhorn-provisioned class, and its class is explicitly
+#           EMPTY so nothing can dynamically provision an empty stand-in;

+# L0 static check (offline, no cluster) — bulk-tier-distinct-from-replicated
+# Serves: R-STATE-04 ("Bulk media storage has a capacity strategy distinct from the
+#                      replicated tier." — spec docs/04-storage-and-state.md)
+#
+# WHY THIS EXISTS — THE BULK TIER WAS A STUB FOR SIX ROADMAP PHASES, AND STUBS ROT QUIETLY
+# ----------------------------------------------------------------------------------------
+# `platform/longhorn/storageclasses.yaml` declared a `bulk` StorageClass from Phase 0 with
+# `provisioner: nfs.csi.k8s.io`, `server: REPLACE-ME`, `share: REPLACE-ME` and a TODO(OQ-2).
+# Four ServiceDefinitions carried a comment promising to attach their media "once OQ-2 is
+# resolved", and each of them said, correctly, that adding `class: bulk` before then would
+# leave the PVC unbound and the pod Pending. So the tier existed as a NAME with nothing
+# behind it, and the only thing preventing a multi-terabyte media library from being
+# authored onto the 3-replica `longhorn` class was four hand-written comments.
+#
+# That is the failure this check makes impossible to reintroduce. R-STATE-04 is not "bulk
+# storage exists" — it is that bulk storage's capacity strategy is DISTINCT from the
+# replicated tier's. Three mini-PCs cannot hold 3x of 8.33 TiB. A bulk volume that lands on
+# `longhorn` does not fail loudly: Longhorn accepts the PVC and starts replicating, and the
+# tier fills up. Distinctness is therefore a property worth asserting statically, on every
+# gate run, rather than trusting to review.
+#
+# It also pins the four decisions that make the STATIC form of this tier safe, each of
+# which has a plausible-looking "simplification" that silently breaks something:
+#
+#   * RECLAIM POLICY. Bulk data pre-exists the cluster, is larger than the cluster, and has
+#     consumers OUTSIDE it. `Retain` is the whole reason a PV is used here instead of an
+#     inline volume. `Delete` on a dynamically-provisioned bulk class would make `kubectl
+#     delete pvc` a data-loss operation.
+#   * NO DYNAMIC PROVISIONING. A dynamic bulk class hands out FRESH EMPTY directories. The
+#     pod mounts successfully, the PVC is Bound, everything is green — and the 8 TiB of
+#     existing data was never attached. This is the single most deceptive failure available
+#     in this tier, so `storageClassName` must be explicitly empty and binding must be
+#     pinned from BOTH ends (claimRef + volumeName).
+#   * `hard`, NOT `soft`. A soft NFS mount converts a server hiccup into a short read or
+#     EIO handed to the application. For a media library that is silent corruption. `hard`
+#     hangs instead — recoverable, where truncated is not.
+#   * NFSv4. v4 carries mount and lock in-protocol, so the tier needs ONE reachable port
+#     (tcp/2049) instead of v3's rpcbind/111 + mountd + statd on ephemeral numbers. That is
+#     a FIREWALL fact as much as a storage one: prod reaches this server through pfSense,
+#     and the number of ports the operator must open is a consequence of this field.
+#
+# AND ONE INVARIANT THAT IS NOT ABOUT STORAGE AT ALL — the EXDEV trap (assertion 6).
+# Sonarr and Radarr import by hardlinking or atomically renaming a finished download into
+# the library. Both are same-filesystem operations, and to the kernel "same filesystem"
+# means SAME MOUNT. Mounting one export twice (say `subPath: tv` and `subPath: downloads`)
+# looks TIGHTER — less of the tree exposed per mount — and breaks `link()` with EXDEV no
+# matter that the server knows they are one dataset. The arrs do not fail loudly on that:
+# they degrade to copy-then-delete, rewriting every imported file over NFS and destroying
+# the seeding copy. The symptom appears weeks later as "imports are slow and my ratio is
+# gone". A reviewer cannot see it, so this check does: one export, at most one mount, per
+# workload.
+#
+# GIVEN the repository as authored,
+# WHEN  every `class: bulk` storage entry in catalog/ is compared against the manifests
+#       render.py produces for it (read from the committed apps/ goldens, i.e. what Flux
+#       actually reconciles — not from the renderer, which would only agree with itself),
+# THEN  (1) DISTINCTNESS: no bulk volume is on the replicated tier. Its PV/PVC
+#           storageClassName is explicitly empty — never `longhorn`, never any class the
+#           repo declares with the Longhorn provisioner — and its PV's source is an
+#           EXTERNAL one (nfs), not a Longhorn volume;
+#       (2) CAPACITY STRATEGY: every bulk PV declares a capacity, and for each service the
+#           bulk volume is at least an ORDER OF MAGNITUDE larger than that service's own
+#           replicated volume. This is the requirement stated as arithmetic: the two tiers
+#           exist because the data has two magnitudes, so a "bulk" volume sized like a
+#           config PVC means the strategy was named and not actually applied;
+#       (3) NOT DYNAMICALLY PROVISIONED, AND PRE-BOUND BOTH WAYS: every bulk PVC names its
+#           PV by volumeName, every bulk PV names its PVC by claimRef (namespace+name), and
+#           the two agree — so no other claim can win a race, and nothing can provision an
+#           empty replacement;
+#       (4) RECLAIM: every bulk PV is `Retain`;
+#       (5) MOUNT SAFETY: every bulk PV declares mountOptions carrying `hard` and an
+#           `nfsvers=4.x`, and carrying NEITHER `soft` NOR an `nfsvers=3`;
+#       (6) ONE EXPORT, ONE MOUNT PER WORKLOAD (the EXDEV trap above);
+#       (7) READ-ONLY IS REAL AND CONSISTENT: a bulk entry declared readOnly renders BOTH
+#           `spec.nfs.readOnly: true` on the PV AND `readOnly: true` on the volumeMount,
+#           and its access mode is ReadOnlyMany; a writable one renders NEITHER and is
+#           ReadWriteMany. Every bulk access mode is a `...Many` — one export is consumed
+#           by several namespaces and several nodes, which ReadWriteOnce cannot express;
+#       (8) AUTHORED ONCE, PROMOTED (the R-ENV-02 seam this tier depends on): every bulk
+#           PV's `nfs.server` is the BARE cluster-vars token, never a literal address; that
+#           knob has a base default; and EVERY environment overlay supplies it — so the two
+#           clusters, which reach this storage by different addresses, cannot be served by
+#           one hardcoded value;
+#   AND (9) LOAD-BEARING + NON-VACUOUS: ci/l0.sh runs this check unconditionally and
+#           ci/gate.sh blocks the merge when the l0 stage fails; and the corpus is NOT
+#           empty — a repo with zero bulk volumes fails here rather than passing trivially,
+#           because a check that is satisfiable by deleting the feature proves nothing.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps)
+#   - Nothing about RUNTIME. Not that the server is reachable, not that the export permits
+#     these clients, not that the PVC binds, not that a write succeeds. The uid analysis in
+#     docs/BULK-NFS-STORAGE.md §6 is reasoning, and the write/hardlink probes in §9 are the
+#     in-cluster proof — they need a cluster and are not run here.
+#   - It cannot prove the prod address is CORRECT, only that it is a supplied knob. While
+#     prod's value is a placeholder, prod's pods will not mount (docs/BULK-NFS-STORAGE.md
+#     §7); catching that needs the placeholder guard, which is absent from main.
+#   - Read-only for the media tree is a CLIENT-side guarantee, and this check can only
+#     assert the client side. The export serves a reader and two writers from the same node
+#     addresses, so the server cannot distinguish them (docs/BULK-NFS-STORAGE.md §5).
+#   - Assertion (2)'s magnitude ratio is a heuristic with a deliberately generous floor. It
+#     catches "bulk volume sized like a config volume", not a subtly wrong capacity — and a
+#     static NFS PV's capacity is advisory anyway, since the ZFS pool is the real limit.
+#   - Assertion (6) reasons over ONE workload's mounts. It cannot see two different
+#     services hardlinking between each other's mounts, which is not a thing that happens.

+# L0 STATIC — dev/test nodes are provisioned as code, end to end  (R-ENV-01)  [EXECUTABLE]
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+# Spec:    docs/00 R-ENV-01 ("dev/test MUST be provisioned as local KVMs via IaC:
+#          created, baselined, cluster-joined, and managed as code"); the four stages
+#          are enumerated in docs/02 §"Node lifecycle stages".
+#
+# WHY L0: R-ENV-01 is a requirement about HOW the dev nodes came to exist, and a live
+# Node object cannot answer it — a node built by OpenTofu and one built by hand in a
+# hypervisor UI are indistinguishable through the Kubernetes API. What is provable, with
+# no cluster, is that a COMPLETE and EXECUTABLE provisioning path exists for all four
+# stages and covers EVERY dev node. For the Ansible half that is proven by DRIVING the
+# real toolchain offline (`--syntax-check`, `--list-hosts` — neither opens a connection
+# to any node), not by reading files: a chain that does not resolve fails the check.
+#
+# ENVIRONMENT-AGNOSTIC: no hostname, address, prefix or node count appears in the test.
+# The dev group names are read from the playbooks' own default host patterns, the node
+# names are generated from the IaC module's prefix/count variables, and the two sets are
+# compared against each other — so the assertion survives a rename or a resize.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  the provisioning chain is parsed and (where offline execution is possible) driven,
+# THEN  the IaC module creates the dev nodes on a LOCAL KVM hypervisor (allowlisted
+#       provider — a cloud provider fails), from a for_each map rather than a count index,
+#       each with CPU/RAM/OS disk/dedicated Longhorn data disk/NIC/cloud-init seed; the
+#       node set it creates is EXACTLY the set Ansible manages; the baseline stage applies
+#       the package floor, kernel modules, sysctls, data-disk mount, swap-off and iscsid
+#       declaratively; one k3s role founds the cluster with --cluster-init and joins the
+#       rest with --server while disabling flannel/kube-proxy/traefik/servicelb at
+#       install; and site.yml's chain (baseline -> k3s -> Cilium -> verify -> Flux)
+#       resolves and targets every dev node at every stage.
+#
+# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git, PyYAML, and —
+# where present — ansible-playbook in no-connection modes; no cluster, no network);
+# conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this Chainsaw Test
+# wraps the SAME script.
+#
+# KNOWN, DELIBERATE GAPS (enumerated in check.sh's header; this test claims none of them):
+#   * That the RUNNING dev VMs were created by this module — needs the OpenTofu state or
+#     hypervisor access, neither available offline.
+#   * `tofu validate` — needs `tofu init` (provider registry), i.e. network. The module is
+#     parsed, not evaluated; a network-allowed CI stage would close this.
+#   * "Never hand-edited on the box" (docs/02 stage 4's second half) — a live drift check.
+#   * REBUILD/re-converge (docs/02's own proof line) — exercised at L3 by
+#     tests/l3-fault-injection/node-loss (R-STATE-02).
+#   * docs/02 prose puts the baseline in cloud-init; the implementation moved it into the
+#     Ansible node_baseline role. R-ENV-01 requires the node to be "baselined ... as code",
+#     not that cloud-init be the tool, so the check asserts the STAGE and RECORDS the

+# ----------------------------------------------------------------------
+# R-ENV-01 is a requirement about HOW the dev nodes come to exist. The live cluster
+# cannot answer it: a Kubernetes node object looks identical whether it was built by
+# OpenTofu or by hand in a hypervisor UI (there is no API field for "was I created by
+# IaC"). What CAN be proven, with no cluster, is that a COMPLETE, EXECUTABLE
+# provisioning path exists for all four stages and covers every dev node — and, for the
+# Ansible half, that is proven by RUNNING the real toolchain in a no-connection mode
+# (`--syntax-check`, `--list-hosts`) rather than by reading the files, so a chain that
+# does not actually resolve fails here. The IaC half is asserted by parsing the module:
+# `tofu init/validate` needs the provider registry, and L0 is offline by contract.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  the provisioning chain is parsed and (where offline execution is possible)
+#       actually driven,
+# THEN  CREATE:  the IaC module targets a LOCAL KVM hypervisor (every declared provider
+#                is a KVM-family hypervisor provider — no cloud provider may appear),
+#                instantiates its nodes from a for_each map (never a count index, so one
+#                node can be replaced without disturbing its siblings), and gives each
+#                node CPU, RAM, an OS disk, a DEDICATED Longhorn data disk, a NIC and a
+#                cloud-init seed carrying the login user + SSH key;
+#       AND      the node set it creates is EXACTLY the dev node set Ansible manages —
+#                names derived from the module's own prefix/count, so no node can be
+#                hand-added to the inventory or hand-created in the hypervisor;
+#       BASELINE: a baseline stage exists as declarative Ansible (package floor, kernel
+#                modules persisted AND loaded, sysctls, the Longhorn data disk formatted
+#                and mounted, swap off, iscsid enabled), driven by variables with
+#                defaults rather than per-host special cases;
+#       JOIN:    one role installs k3s for both roles of every node — `--cluster-init`
+#                on the primary, `--server` join on the secondaries — with flannel,
+#                kube-proxy, traefik and servicelb disabled AT INSTALL, and Cilium
+#                installed as the CNI afterwards;
+#       MANAGE:  site.yml chains baseline -> k3s -> Cilium -> verify -> Flux bootstrap;
+#                `ansible-playbook --syntax-check` on that chain SUCCEEDS; and
+#                `--list-hosts` shows every one of those stages targeting EVERY dev
+#                node, so no node is outside the code path.
+#
+# ENVIRONMENT-AGNOSTIC: no hostname, address, prefix or node count is written down here.
+# The dev group names come from the playbooks' own default host patterns, the node names
+# from the IaC module's prefix/count variables, and the two sets are compared to each
+# other. This check therefore keeps working when the estate is renamed or resized.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
+#   - That the RUNNING dev VMs were in fact created by this module. Nothing offline can:
+#     it would need the OpenTofu state (a remote R2 backend + credentials) or hypervisor
+#     access. `tofu plan` against the live estate is the operator's own check.
+#   - That the module APPLIES cleanly. `tofu validate` needs `tofu init`, which downloads
+#     the provider from the registry; L0 is offline by contract, so the module is parsed,
+#     not evaluated. ci/lint.sh does not cover .tf either — a gap worth closing in CI
+#     with a network-allowed stage, not here.
+#   - "Never hand-edited on the box" (stage 4's second half) — a drift check against the
+#     live nodes, which is an operator/Ansible-check-mode exercise, not a repo property.
+#   - REBUILD/re-converge ("destroy a dev node VM and rebuild it", docs/02's own proof
+#     line) — that is exercised at L3 by tests/l3-fault-injection/node-loss (R-STATE-02).
+#   - That the baseline actually ran on a node (cluster/host state), and that the
+#     hypervisor is on the operator's own LAN rather than remote — "local" is asserted as
+#     "a KVM hypervisor provider driving a self-hosted endpoint variable", not as a
+#     network topology fact.
+#   - DEVIATION FROM docs/02 PROSE, ASSERTED DELIBERATELY: docs/02 describes stage 2 as
+#     cloud-init applying the OS baseline. The implementation moved the rich baseline into
+#     the Ansible `node_baseline` role (cloud-init keeps hostname/user/SSH/network),
+#     because Proxmox provisioning is API-only and a custom cloud-init snippet needs
+#     SSH/SFTP to the hypervisor. R-ENV-01's own wording requires the node to be
+#     "baselined ... as code", not that cloud-init be the tool, so this check asserts the
+#     STAGE, wherever it lives, and records the divergence rather than hiding it.

+# Spec:    docs/00 R-NET-04 ("The platform MUST support **multiple egress paths** selected by
+#          routing rules ... realized as two paths — the local `internet` path and the
+#          in-cluster `vpn` path — not multi-ISP routing"), elaborated by docs/03 §"Egress
+#          routing: two paths, one physical WAN": "the `internet` path is simply the default
+#          route out"; "**Default is the WAN; the VPN is strictly opt-in.** Every pod — and
+#          the nodes themselves — egress the local/private WAN by default and **never** the
+#          VPN. Only services labeled `egress-class=vpn` are steered to the tunnel, and the
+#          kill-switch blackholes **only** that class."
+#
+# WHAT THIS ADDS OVER R-NET-05/07 (already covered, and NOT re-tagged here)
+# ------------------------------------------------------------------------
+# R-NET-05/07 are about a SERVICE — it declares a class, enforcement is outside it, the class
+# flips via GitOps — and are proven by tests/l1-rendering/egress-class-render and
+# tests/l2-behavioral/egress-class. R-NET-04 is about the PLATFORM's PATH SET and the RULES
+# that select among them, which nothing else asserts:
+#   * exactly TWO paths, the same closed set in the schema, the admission policy and the
+#     renderer (a third value would be a path nothing routes; "multi-ISP" is out of scope);
+#   * selection is by a ROUTING RULE and the rule set is TOTAL AND DISJOINT — exactly one
+#     Cilium steering rule, selecting only `egress-class=vpn`, and on the gateway node one
+#     `ip rule` scoped to the tunnel address. NOTHING selects the `internet` class, because
+#     absence of a matching rule IS the default path;
+#   * the two paths COEXIST per DESTINATION: private space is excluded from the tunnel, so a
+#     vpn-class pod's cluster/LAN traffic still takes the local path;
+#   * the vpn path never becomes the DEFAULT — its default route lives in a dedicated routing
+#     table, `route-noexec` is set and a pushed `redirect-gateway` is ignored;
+#   * the kill-switch blackholes ONLY that class — the nft chain's policy is accept and every
+#     DROP is scoped to the vpn class's own source set/fwmark, so `internet` fails OPEN.
+#     (R-NET-06's opposite claim, that `vpn` fails CLOSED, is L3's vpn-killswitch.)
+#
+# WHY L0: every clause above is a statement about ALL rules — including rules that must be
+# ABSENT (nothing selects the default path; no unscoped rule; no unqualified drop; no default
+# route in the main table). A cluster can show which path two pods took; it cannot show that
+# no third rule exists or that the vocabulary is closed.
+#
+# ENVIRONMENT-AGNOSTIC: no address appears. The private ranges the tunnel must exclude are
+# checked as CONTAINMENT of the addresses each environment's own Flux overlay declares (pod
+# CIDR, Gateway VIP, LB pool, API host), so a new environment on a different LAN is checked
+# against its own values.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  the egress vocabulary, every CiliumEgressGatewayPolicy, the gateway node's policy
+#       routing / OpenVPN / nftables templates, and every environment's overlay addresses are
+#       parsed and cross-checked,
+# THEN  there are exactly two paths with `internet` as the default; exactly one steering rule
+#       selects exactly the vpn class by label; the gateway is selected by node label with a
+#       named egress interface; all RFC1918 space and every address any environment assigns
+#       itself is excluded from the tunnel; the tunnel's default route and its fail-closed
+#       blackhole live only in a dedicated routing table behind a scoped `ip rule`; OpenVPN
+#       cannot take the main table; and no nftables DROP is unscoped.
+#
+# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git tree + PyYAML; no
+# cluster, no network); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this
+# Chainsaw Test wraps the SAME script.

+# L0 static check (offline, no cluster) — egress-paths-selected-by-rules
+# Serves: R-NET-04 ("The platform MUST support **multiple egress paths** selected by routing
+#         rules. Per OQ-1 the environment has **one physical commercial WAN and no
+#         multi-ISP plans**, so this is realized as two paths — the local `internet` path and
+#         the in-cluster `vpn` path — not multi-ISP routing. Physical multi-WAN (multiple ISP
+#         uplinks) is **out of scope** unless a future ADR reopens it."
+#         — spec docs/00-vision-and-scope.md).
+#
+# The elaborating spec text this check quotes and asserts against — docs/03
+# §"Egress routing: two paths, one physical WAN (R-NET-04/05 — resolved by OQ-1)":
+#     | `internet` | Out the single commercial WAN | Normal pod egress via node -> SOHO edge
+#                                                    router -> internet |
+#     | `vpn`      | Routed through the in-cluster VPN tunnel | Steered to the shared VPN
+#                                                    egress gateway (ADR-0013) |
+#     "**Physical multi-WAN (multi-ISP) is out of scope.** With a single WAN there is nothing
+#      to policy-route across; the `internet` path is simply the default route out."
+#     "**Default is the WAN; the VPN is strictly opt-in.** Every pod — and the nodes
+#      themselves — egress the local/private WAN by default and **never** the VPN. Only
+#      services labeled `egress-class=vpn` are steered to the tunnel, and the kill-switch
+#      blackholes **only** that class."
+#     "It is **split-tunnel**: it creates `tun0` but does **not** set the node's default
+#      route (`route-noexec` + policy routing), so the node's own traffic stays on the WAN —
+#      only what Cilium points at `tun0` uses the VPN."
+#
+# WHAT R-NET-04 ADDS OVER R-NET-05/07 (which are ALREADY covered) — READ THIS FIRST
+# ---------------------------------------------------------------------------------
+# R-NET-05/07 are about a SERVICE: it can declare its class, enforcement happens outside it,
+# and the class can be flipped via GitOps. Those are proven by
+# tests/l1-rendering/egress-class-render (the render) and tests/l2-behavioral/egress-class
+# (two labelled pods observe two different public IPs, and a relabel re-routes the same pod).
+# Re-tagging either of those with R-NET-04 would be a duplicate wearing a new label.
+#
+# R-NET-04 is about the PLATFORM's PATH SET and the RULES THAT SELECT AMONG THEM. Its
+# distinctive content — none of which any existing test asserts — is:
+#
+#   (1) THERE ARE EXACTLY TWO PATHS, and the same two everywhere. The class vocabulary is
+#       one closed set of two values agreed by the schema, the admission policy and the
+#       renderer. A third value appearing in one of them but not the others would be a path
+#       nothing routes (or a path nothing validates); "multi-ISP" reappearing as a third
+#       class would contradict OQ-1's resolution.
+#   (2) SELECTION IS BY A ROUTING RULE, and the rule set is TOTAL AND DISJOINT. The `vpn`
+#       path is entered only via rules that select the vpn class — a Cilium
+#       CiliumEgressGatewayPolicy pod-selector, and on the gateway node an `ip rule` scoped
+#       to the tunnel source address. Nothing selects the `internet` class, because
+#       "the `internet` path is simply the default route out": ABSENCE of a matching rule IS
+#       the default path. So an unlabelled pod, and an `internet`-class pod, take the WAN.
+#   (3) THE PATHS COEXIST — the choice is per-destination, not per-pod-lifetime. The vpn
+#       rule tunnels public destinations while EXCLUDING all private space, so a vpn-class
+#       pod's cluster/LAN traffic still takes the local path at the same time as its
+#       internet traffic takes the tunnel.
+#   (4) THE VPN PATH NEVER BECOMES THE DEFAULT. Split tunnel: the tunnel's default route
+#       lives in a DEDICATED routing table reached only through the scoped rule, the
+#       provider's pushed `redirect-gateway` is ignored, and `route-noexec` keeps OpenVPN
+#       from touching the main table. Otherwise there would be one path (the VPN), not two.
+#   (5) THE KILL-SWITCH BLACKHOLES ONLY THAT CLASS. The blackhole default is inside the
+#       dedicated table; the nftables chain's policy is ACCEPT and every DROP is qualified
+#       by the vpn class's own source set / fwmark. The `internet` path therefore fails
+#       OPEN and can never be blackholed. (R-NET-06's opposite claim — that `vpn` fails
+#       CLOSED — is proven at L3 by tests/l3-fault-injection/vpn-killswitch. This check
+#       asserts the OTHER direction, which that test does not.)
+#
+# WHY L0. Every clause above is a property of the RULE SET, i.e. of authored configuration:
+# totality ("nothing selects the default path"), disjointness ("exactly one rule, selecting
+# exactly one class"), and scoping ("no unqualified drop, no default route in the main
+# table") are statements about ALL rules, including the ones that would have to be absent.
+# A running cluster can show you which path two pods took; it cannot show you that no third
+# rule exists, that no rule is unscoped, or that the vocabulary is closed. The behavioural
+# complement — that an UNLABELLED pod really does take the WAN path — is at L2 in
+# tests/l2-behavioral/egress-default-path (same requirement label).
+#
+# ENVIRONMENT-AGNOSTIC: no address is written down. The private ranges the vpn rule must
+# exclude are checked as CONTAINMENT of the addresses each environment's own Flux overlay
+# declares (pod CIDR, Gateway VIP, LB pool, API host) — so a new environment on a different
+# LAN is checked against its own addresses, and the check keeps working when they change.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this check as claiming them):
+#   - Behaviour. That a vpn-class pod's packets really leave via tun0, that an unlabelled
+#     pod's really do not, and that the tunnel is up at all. L2 covers the two labelled
+#     classes (tests/l2-behavioral/egress-class, R-NET-05) and the unlabelled default
+#     (tests/l2-behavioral/egress-default-path, R-NET-04); the kill-switch firing is L3.
+#   - THE RUNNING NODE's routing tables and nftables ruleset. This reads the templates that
+#     generate them, driven by no node. A hand-added `ip rule` on the gateway node is
+#     invisible here (and to every other test); drift on the box is an Ansible check-mode
+#     exercise for the operator.
+#   - PHYSICAL MULTI-WAN. Out of scope per OQ-1, so its absence is not asserted: there is no
+#     honest repository signal that would distinguish "one WAN, correctly" from "one WAN,
+#     because nobody tried" — and inventing one would be a hollow assertion.
+#   - IPv6. The policy's CIDRs and the routing rules are IPv4-only, matching the platform.
+#     If IPv6 egress is ever enabled, the `internet` path would need the same analysis and
+#     this check would NOT catch its absence.

+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+# Spec:    docs/00 R-PLAT-01 ("The platform MUST run on k3s across 3 nodes with
+#          production-grade HA control plane in prod; dev/test MAY run fewer nodes but MUST

+#
+# WHY L0: R-PLAT-01 has an authored half and an observed half. The authored half — that the

+# from one code path, with exactly one --cluster-init founder, no external datastore, and a
+# floating API endpoint that is SAN'd into the serving cert and cannot collide with the
+# Service-LB allocator — is provable with no cluster and is ONLY provable here: a live
+# cluster cannot tell you what the NEXT environment brought up from this repo would look
+# like. The observed half is asserted separately at L2 by
+# tests/l2-behavioral/ha-control-plane, which carries the same requirement label.
+#
+# ENVIRONMENT-AGNOSTIC: no hostname, address, node count or group name is written down.
+# Environments are enumerated from the R-ENV-02 seam itself (k3s_primary_group /
+# k3s_servers_group in group_vars), and WHICH one is prod is derived from the Flux overlay
+# that environment bootstraps (flux_bootstrap_env_path) — never from a group's name.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  the inventory, the k3s_server and kube_vip roles, their plays and each
+#       environment's Flux overlay are parsed and cross-checked against each other,
+# THEN  k3s is the pinned distro and nothing is installed as an agent; every environment
+#       resolves to an ODD, quorum-capable server count (prod exactly three) with EXACTLY
+#       ONE --cluster-init founder and every other server joining it with --server;
+#       the datastore is k3s's embedded etcd (no --datastore-endpoint, no --disable-etcd);
+#       the API's floating endpoint is a leader-elected, control-plane-ONLY kube-vip
+#       DaemonSet on every server whose address is the environment-scoped VIP, that VIP is
+#       in the apiserver serving cert's SANs together with every server's own address, and
+#       it is neither a node address nor the ingress Gateway VIP nor inside that
+#       environment's Cilium LoadBalancer pool; and dev/test and prod are built by the SAME
+#       roles and plays retargeted by variables only.
+#
+# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git tree + PyYAML; no
+# cluster, no network); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this
+# Chainsaw Test wraps the SAME script.
+#
+# KNOWN, DELIBERATE GAPS (enumerated in check.sh's header; this test claims none of them):
+#   * The LIVE clusters' shape (three Ready servers, all etcd members, VIP actually floating,
+#     API answering through it) — asserted at L2 by tests/l2-behavioral/ha-control-plane.
+#   * FAILOVER. That the control plane survives losing a server (quorum holds, the VIP moves)
+#     is a fault-injection claim and is proven NOWHERE yet — tests/l3-fault-injection/node-loss
+#     drains a node for R-STATE-02's data claim and asserts nothing about the control plane.
+#   * "Production-grade" as a hardware/performance judgement (operator decision, §2 of
+#     infra/PROD-PROVISIONING.md).
+#
+# TWO GAPS CLOSED 2026-09-06 (they used to be listed above; recorded so the change is legible):
+#   * `K3S_API_HOST` (Cilium's k8sServiceHost) was the PRIMARY NODE's address in both
+#     environments rather than the floating VIP, contradicting the prod overlay's own comment.
+#     It was ESCALATED, not asserted, because the workstream could not decide it (R-TEST-06).
+#     The operator decided the VIP, so it is now ASSERTED — on both sides of the [parity]
+#     contract and per environment.
+#   * kube-vip was NOT imported by playbooks/site.yml. It is now, BETWEEN k3s and cilium, and
+#     the order is asserted — not as a tidiness preference but because the CNI's endpoint is
+#     the VIP, so an unfloated VIP means a cold build brings up a CNI that cannot reach its

+# ---------------------------------------------------------------------
+# R-PLAT-01 splits cleanly in two, and the halves are provable at different layers:
+#
+#   AUTHORED half — "the configuration in git builds a 3-server HA embedded-etcd control
+#       plane in BOTH environments, from ONE code path": provable with no cluster, and
+#       ONLY provable here. A live cluster cannot tell you whether the *next* environment
+#       brought up from this repo will also be HA, whether a second `--cluster-init`
+#       founder could exist, or whether an external datastore is configured anywhere. That
+#       is this check.
+#   OBSERVED half — "the cluster this suite is pointed at really is 3 Ready servers, all
+#       etcd members, with the API answering through the floating VIP": that is cluster
+#       state and lives in tests/l2-behavioral/ha-control-plane (same requirement label).
+#
+# Neither half is sufficient alone, and this file claims only the first.
+#
+# ENVIRONMENTS ARE DERIVED, NOT LISTED. The check does not know the words "dev" or "prod"
+# as inventory names. It enumerates environments from the R-ENV-02 seam itself — the
+# `k3s_primary_group` / `k3s_servers_group` pair in group_vars/all.yml plus every
+# group_vars/<group>/vars.yml that overrides them — and identifies WHICH environment is
+# prod by the Flux overlay that environment bootstraps (`flux_bootstrap_env_path`), not by
+# its group name. Add a fourth prod node, rename a group, or add a third environment and
+# the assertions follow; nothing here restates an address, a hostname or a node count.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  the Ansible inventory, the k3s/kube-vip roles and plays, and each environment's
+#       Flux overlay are parsed and cross-checked against each other,
+# THEN  DISTRO:   k3s is the distro, pinned, installed by the one role, and no node is
+#                 installed as an `agent` (an agent is not a control-plane member);
+#       SERVERS:  every environment's server group resolves to a quorum-capable, ODD
+#                 number of hosts (>= 3, tolerating >= 1 loss), the PROD environment to
+#                 EXACTLY three, and each has EXACTLY ONE `--cluster-init` founder while
+#                 every other server joins it with `--server` (so a second founder — the
+#                 split-brain shape — cannot be authored);
+#       ETCD:     the datastore is k3s's EMBEDDED etcd: no `--datastore-endpoint` and no
+#                 `--disable-etcd` anywhere in the provisioning code, so every server is
+#                 an etcd member (docs/02's "no external datastore", "on all 3");
+#       ENDPOINT: the API has a floating endpoint that survives losing the founder — the
+#                 kube-vip VIP is control-plane-only (never Service LB, or it would fight
+#                 Cilium LB-IPAM for ARP), leader-elected, deployed to EVERY server, and
+#                 baked into the apiserver serving cert's SAN list ALONG WITH every
+#                 server's own address (so TLS validates whichever node answers);
+#       ADDRESSES: each environment's control-plane VIP is not one of its node addresses,
+#                 is not that environment's ingress Gateway VIP, and lies OUTSIDE that
+#                 environment's Cilium LoadBalancer pool — the two allocators can never be
+#                 handed the same address;
+#       CNI PATH: the CNI dials the FLOATING endpoint, not a machine (added 2026-09-06). The

+#                 kube_vip_address and feeds Cilium's k8sServiceHost — the Flux overlay's
+#                 K3S_API_HOST equals that environment's VIP and is none of its node
+#                 addresses ([parity], both halves), the HelmRelease keeps a per-environment
+#                 token rather than a literal, and site.yml floats the VIP BETWEEN k3s and
+#                 Cilium with roles/kube_vip blocking until it answers;
+#       ONE PATH: dev/test and prod are brought up by the SAME role and the SAME plays,
+#                 retargeted by variables only (docs/02 "the *same* Ansible bootstrap
+#                 runs"), so "exercise the same multi-node topology" is a property of the
+#                 code rather than a coincidence of two hand-written inventories.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this check as claiming them):
+#   - THE LIVE CLUSTERS. That three nodes are Ready, that all three are etcd members with
+#     a healthy quorum, that kube-vip is actually floating the VIP, and that the API
+#     answers through it. All of that is asserted at L2 by
+#     tests/l2-behavioral/ha-control-plane, which reads it from the cluster under test.
+#   - FAILOVER. That the control plane SURVIVES the loss of a server (etcd quorum holds,
+#     the VIP moves, the API stays up) is a fault-injection claim. The nearest existing
+#     coverage is tests/l3-fault-injection/node-loss, which drains a node for R-STATE-02's
+#     data-availability claim and does NOT assert control-plane survival. A dedicated
+#     "kill the VIP leader / kill the founder" L3 test is the remaining R-PLAT-01 gap and
+#     is NOT claimed here or at L2.
+#   - "PRODUCTION-GRADE" AS A HARDWARE/OPERATIONS JUDGEMENT. Whether three converged
+#     mini-PCs with etcd sharing a spindle with Longhorn is production-grade is an operator
+#     decision recorded in infra/PROD-PROVISIONING.md §2, not a repository property. This
+#     check asserts the control-plane TOPOLOGY the spec fixes, not a performance verdict.
+#   - IPv6 / dual-stack, and any claim about the edge network.
+#
+# TWO FORMER GAPS ARE NOW ASSERTED, and the reasoning is worth keeping (2026-09-06):
+#   * CILIUM'S OWN API ENDPOINT used to be listed here as an ESCALATION — `K3S_API_HOST`
+#     (clusters/*/kustomization.yaml), which becomes Cilium's `k8sServiceHost`, was each
+#     environment's PRIMARY NODE address rather than the floating VIP, contradicting the prod
+#     overlay's own comment. Making the check fail over it would have turned the merge gate
+#     red on a design question this workstream may not decide (R-TEST-06), so it was reported
+#     instead. THE OPERATOR DECIDED THE VIP on 2026-09-06, which turns the question into a
+#     repository invariant, and invariants belong in assertions — see the "THE CNI DIALS THE
+#     VIP" section. Note what made it assertable: the fix SPLIT one variable in two, so there
+#     is finally an HA-valued name (`k3s_apiserver_endpoint`) to point the contract at.
+#   * kube-vip WAS NOT PART OF THE ONE-COMMAND BRING-UP (site.yml chained node-baseline ->
+#     k3s -> cilium -> verify -> flux-bootstrap), which was recorded here as an observation
+#     and not asserted, because R-PLAT-01 does not fix the bring-up order. It is asserted now
+#     for a different reason that IS in scope: with the CNI's endpoint being the VIP, an
+#     unfloated VIP means a cold build installs a CNI that cannot reach its API server. The
+#     ordering is no longer a preference about tidiness, it is a dependency of the control
+#     plane coming up at all.

+#
+# R-IDP-03 (identity config is declarative) and R-IDP-04 (IdP secrets SOPS-encrypted)
+# are both implemented through ONE mechanism that FAILS OPEN: the KeycloakRealmImport
+# resolves each client's secret from a `(env:NAME)` placeholder mapped to a key of the

+# placeholder it stores the LITERAL placeholder text as the client secret AND THE IMPORT
+# JOB STILL REPORTS SUCCESS — then rests at Done=True / Started=False and never re-runs.
+#
+# Measured 2026-09-06: prod had all 12 clients holding the literal placeholder (every
+# OIDC login failed with "Invalid client or Invalid client credentials"); dev had exactly
+# one (oauth2-proxy), because that Secret key was added AFTER dev's import completed.
+# Declarative config that silently does not apply is not declarative config.
+#
+# GIVEN the repository as authored,
+# THEN  every confidential client declares a placeholder, every placeholder is defined,
+#       resolves to the keycloak-realm-clients Secret, and names a key that EXISTS in the
+#       SOPS file under the `<clientId>-client-secret` contract the reconciler derives
+#       from; public clients declare no secret; the Flux Kustomization applying the Secret
+#       is a transitive `dependsOn` ancestor (wait: true) of the ones applying the import
+#       and the reconciler — a real edge, not a comment; the reconciler is reconciled from
+#       BOTH cluster entrypoints, mounts only what it needs, carries no ServiceAccount
+#       token and contains no dollar sign; and its own `--selftest` (extracted from the

+# L0 static check (offline, no cluster) — keycloak-client-secret-reconciler
+# Serves: R-IDP-03 ("Identity config (realms, clients, groups, roles) is declarative."
+#                   — spec docs/15-identity-and-access.md)
+#         R-IDP-04 ("IdP secrets SOPS-encrypted; MFA available."
+#                   — spec docs/15-identity-and-access.md)
+#
+# WHY THIS EXISTS — THE REALM IMPORT IS A ONE-SHOT THAT FAILS OPEN
+# ---------------------------------------------------------------
+# platform/keycloak/keycloak-realm-import.yaml declares 12 confidential OIDC clients
+# whose secrets are `(env:NAME)` import placeholders, mapped by spec.placeholders to
+# keys of the SOPS-encrypted keycloak-realm-clients Secret. Measured on both clusters
+# on 2026-09-06:
+#
+#   * when the Keycloak Operator cannot resolve a placeholder it stores the LITERAL
+#     placeholder text as the client secret AND THE IMPORT JOB STILL REPORTS SUCCESS;
+#   * the KeycloakRealmImport then rests at Done=True / Started=False and NEVER
+#     re-runs, so it never self-heals.
+#
+# Consequence: on prod all 12 clients held the literal placeholder and every OIDC
+# login on the cluster failed ("Invalid client or Invalid client credentials"); on dev
+# exactly one (oauth2-proxy) was broken, because that Secret key was added AFTER dev's
+# import had already completed and a completed import is never re-run.
+#
+# Nothing in the repo asserted the declaration was self-consistent, and nothing
+# corrected the realm afterwards. This check is the static half of the fix (the
+# reconciler CronJob is the runtime half, and this check proves that too).
+#
+# GIVEN the repository as authored,
+# THEN  (1) DECLARATION IS COMPLETE: every confidential client in the realm import
+#           declares a secret placeholder; every placeholder it uses is defined in
+#           spec.placeholders; every placeholder resolves to the keycloak-realm-clients
+#           Secret; and every referenced key EXISTS in the SOPS file. A client whose
+#           key is missing is exactly the dev failure, and it is now unmergeable.
+#       (2) THE NAMING CONTRACT HOLDS: each key is `<clientId>-client-secret`. That is
+#           what lets the reconciler derive the client set from the mounted Secret with
+#           no second declaration — so it must be enforced, not assumed. No orphan
+#           placeholder, and no orphan Secret key (an orphan key would make every
+#           reconciler run fail with NOT FOUND).
+#       (3) PUBLIC CLIENTS DECLARE NO SECRET (the `kubernetes` client is PKCE-public;
+#           giving it a secret would be a silent downgrade).
+#       (4) ORDERING IS A REAL FLUX EDGE, NOT A COMMENT: the Flux Kustomization that
+#           renders the Secret is a transitive `dependsOn` ancestor — with `wait: true`
+#           — of the one that renders the realm import and the reconciler. The repo's
+#           hard-won rule: a dependency that is only DOCUMENTED is not a dependency.
+#       (5) THE RECONCILER IS WIRED AND SAFE: it is reconciled from BOTH cluster
+#           entrypoints, mounts exactly the two Secrets it needs at the paths its code
+#           defaults to, carries no ServiceAccount token, and contains no dollar sign
+#           (it ships inside a substituted Flux path, where an unescaped dollar-brace
+#           expansion is rewritten before any container runs).
+#       (6) THE RECONCILER'S BEHAVIOUR IS PROVEN, NOT ASSERTED: this check EXTRACTS the
+#           script from the ConfigMap and executes its `--selftest`, which drives the
+#           real code paths against an in-process stub Keycloak and asserts
+#           compare-then-write, idempotence (zero writes on a converged realm),
+#           no-secret-logging, the endpoint allow-list (users/groups/roles are
+#           unreachable) and fail-closed behaviour. What CI proves is byte-for-byte
+#           what ships.
+#   AND (7) THIS CHECK IS LOAD-BEARING: ci/l0.sh runs it unconditionally, ci/gate.sh
+#           blocks the merge when the l0 stage fails, ci/touched-requirements.sh maps
+#           platform/keycloak/ to these requirement IDs, and an L2 test exists that
+#           audits the LIVE realm. An unreferenced test is precisely the "looks applied
+#           and isn't" failure this repo keeps hitting.
+#
+# NOT proven here (named honestly, in the style of the sibling L0 checks):
+#   - that the LIVE realm's stored secrets match git. That is cluster state; it is
+#     conformance/tests/l2-behavioral/keycloak-client-secrets-match-git.
+#   - that the SOPS ciphertext decrypts to a usable secret. Key PRESENCE is checkable
+#     offline; the plaintext is not, and must not be.
+#   - that the CronJob's image can be pulled or its schedule fires.

+#
+# THE BUG CLASS THIS CLOSES (it has now bitten three times in one file). A guard in
+# `bootstrap/standup.sh` keys on the SHAPE of a value that lives in
+# `clusters/base/cluster-vars.yaml`, and nothing tied the two together. On 2026-09-05 the
+# S3 placeholder changed from `TBD-PROD-S3-BACKUP-ENDPOINT` to
+# `https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com`; the three guards matched the glob
+# `TBD-*`, a PREFIX match, and `fnmatch('https://TBD-R2-…','TBD-*')` is False. All three
+# guards silently stopped matching, and `standup.sh resume` would have resumed `velero` on
+# prod against a nonexistent hostname: installs clean, reports healthy, NO BACKUPS EXIST.
+# It was found by accident. The guard is fixed (`s3_is_placeholder`, substring); the
+# COUPLING was untested, which is what makes the class reintroducible.
+#
+# GIVEN the repository as authored,
+# WHEN  the REAL predicate is extracted from bootstrap/standup.sh and executed by bash
+#       (never reimplemented — see check.sh "HOW THE REAL GUARD IS EXERCISED"),
+# THEN  (1) every authored value of a guarded knob that is placeholder-shaped by an
+#           INDEPENDENT detector is actually refused by that guard, in base and in every
+#           environment overlay;
+#       (2) no environment overlay carries a placeholder-shaped value for a knob no guard
+#           refuses;
+#       (3) every function in standup.sh that reads a guarded knob applies the guard to it
+#           (the "three guards died at once" regression);
+#       (4) the guard matches its own vocabulary ANYWHERE in a value, not just as a prefix
+#           — the exact anchoring defect above — and still accepts a real endpoint;
+#   AND (5) the extraction is faithful, and the check fails LOUDLY rather than silently
+#           testing a copy if the guard stops being a self-contained predicate.
+#

+# and that the guard runs at all in a real standup (the dispatch path is shell, executed

+# WHY THIS EXISTS — A GUARD KEYED ON A VALUE THAT LIVES IN ANOTHER FILE
+# --------------------------------------------------------------------
+# `bootstrap/standup.sh` refuses to resume tiers whose configuration is still a
+# placeholder. Three of those guards keyed on the SHAPE of `S3_BACKUP_ENDPOINT`, which is
+# authored in `clusters/base/cluster-vars.yaml`. On 2026-09-05 the placeholder changed
+# from `TBD-PROD-S3-BACKUP-ENDPOINT` to `https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com`
+# (the MinIO -> Cloudflare R2 move). The guards matched the glob `TBD-*` — a PREFIX match —
+# and `fnmatch('https://TBD-R2-…','TBD-*')` is FALSE. All three guards silently stopped
+# matching. `standup.sh resume` would then have resumed `velero` on prod against a hostname
+# that does not exist: the HelmRelease installs clean, the Kustomization reports Ready, and
+# NO BACKUPS EXIST. The only reason it was not shipped is that someone noticed by accident.
+#
+# The predicate is fixed (`s3_is_placeholder`, substring match). The COUPLING is what was
+# never tested: a guard in one file keying on a value in another, with nothing tying them
+# together. This check is that tie, and it is derived from BOTH real files — no current
+# string is hardcoded here, so it does not rot when the placeholder or the guard changes.
+#
+# HOW THE REAL GUARD IS EXERCISED (and why not a copy)
+# ---------------------------------------------------
+# `bootstrap/standup.sh` is NOT sourceable: at top level it parses argv, hard-exits when
+# --kubeconfig/--expect-server/<step> are absent, `cd`s to the repo root, exports
+# KUBECONFIG, installs an EXIT trap and finally dispatches steps against a live cluster.
+# So this check EXTRACTS the predicate's own source lines from the file and sources ONLY
+# those, then calls the real function. That is the real bytes, not a reimplementation:
+#   * every function whose name ends `_is_placeholder` is discovered, not named here;
+#   * a duplicate definition of one is a failure (which of the two would run?);
+#   * the extracted body must be a SELF-CONTAINED predicate — `case`/`return` and nothing
+#     else, no command substitution, no call to another function. If the guard ever grows
+#     a dependency, extraction stops being faithful and THIS CHECK FAILS LOUDLY, naming the
+#     remedy (move the predicate into a small sourceable library that standup.sh sources)
+#     rather than quietly falling back to testing a copy of the logic;
+#   * a CANARY pins the extraction itself: the extracted function must refuse the empty
+#     string and accept a realistic endpoint. An extraction that grabbed the wrong lines,
+#     or a predicate degraded to always-true / always-false, fails there — this repo has
+#     already been bitten by a check that passed when perturbed because it asked a question
+#     that was always satisfiable.
+# There is deliberately NO second implementation of the matching logic anywhere in this file.
+#
+# THE INDEPENDENT DETECTOR (the other half of the comparison)
+# ----------------------------------------------------------
+# Asking "does the guard agree with the guard?" proves nothing, so the set of
+# placeholder-shaped values is decided by a detector written HERE, whose vocabulary is the
+# UNION of two independent sources:
+#   * SEED — universal loud-placeholder idioms (TBD, TODO, FIXME, PLACEHOLDER, REPLACE-ME,
+#     CHANGE-ME, FILL-ME, SET-ME, XXXX), plus `<angle-bracket>` templates and the empty
+#     string. These are NOT derived from the guard, so DELETING a guard arm cannot make a
+#     value stop being placeholder-shaped — it makes assertion (1) fail, which is the point.
+#     A value using an idiom the guard does not know is a finding either way: fix it by
+#     giving the knob a real value, or by teaching the guard the idiom.
+#   * the guard's OWN vocabulary, read out of its case-arms with the glob anchors STRIPPED.
+#     Stripping the anchors is what makes the comparison non-circular in the dimension that
+#     actually broke: the detector matches a word ANYWHERE, case-insensitively, and the
+#     guard must agree. A prefix-anchored guard cannot pass.
+#
+# GIVEN the repository as authored,
+# WHEN  the real predicate(s) are extracted from bootstrap/standup.sh and executed,
+# THEN  (1) VALUES: for every knob a guard is responsible for, every authored value — the
+#           base default AND each environment overlay's value — that the independent
+#           detector calls placeholder-shaped is REFUSED by the real guard, and every value
+#           it calls usable is ACCEPTED (a guard that refuses a real endpoint leaves velero
+#           suspended forever, which is the same class of silent failure);
+#       (2) OVERLAYS: no environment overlay's EFFECTIVE cluster-vars carries a
+#           placeholder-shaped value for a knob that no guard refuses. (Base alone is
+#           exempt: it is not a bootstrap target — `flux bootstrap --path=clusters/<env>` —
+#           and its loud sentinels exist precisely to be overridden. A base placeholder an
+#           overlay forgets to override IS caught, because it becomes that overlay's
+#           effective value.)
+#       (3) CONSUMERS: every function in standup.sh that reads a guarded knob (via `cvar`,
+#           following one hop of variable aliasing) applies a placeholder guard to it. This
+#           is the "all three guards died at once" regression stated as a property: the
+#           guard being correct is worthless if a consumer stops calling it.
+#       (4) ANCHORING: for each word in the guard's own vocabulary, the guard refuses a
+#           value carrying that word in the MIDDLE (not at the start) — the precise defect
+#           of 2026-09-05 — while still accepting a realistic endpoint.
+#       (5) HARNESS: exactly one definition per predicate, the extracted body is verbatim
+#           from the file and self-contained, the canary holds, no divergent second copy of
+#           the matching logic exists elsewhere in standup.sh, and a floor on the number of
+#           assertions run keeps a pass from degenerating into a no-op.
+#   AND (6) LOAD-BEARING: ci/l0.sh runs the L0 conformance layer on every gate run and
+#           ci/gate.sh sets the merge block when that stage fails.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps)
+#   - Nothing about RUNTIME: not that the endpoint resolves, not that credentials work, not
+#     that a backup exists. `standup.sh s3check` probes reachability from a pod (operator-
+#     run, cluster-gated) and conformance/tests/l3-fault-injection/dr-restore proves restore.
+#   - It does not execute standup.sh's dispatch path, so it cannot prove the guard is
+#     REACHED in a real run — only that, when reached, it refuses what it must. The
+#     consumer property (3) is a static approximation of reachability: it is a text-level
+#     taint trace over one file, not an interpreter, and a guard whose result is computed
+#     and then ignored would satisfy it.
+#   - It says nothing about guards keyed on shapes OTHER than placeholders (e.g. the
+#     EXTERNALDNS_TXT_OWNER_ID == 'default' test), nor about placeholder-shaped values
+#     outside cluster-vars (the Ansible inventory's BLOCKED/NOT-A-DEVICE sentinels are
+#     asserted by the node_baseline role itself, at play time).
+#   - Stage 3b of ci/l0.sh scopes the conformance run to the TOUCHED requirements. An edit
+#     to bootstrap/* attributes NO requirement in ci/touched-requirements.sh's path map, so
+#     the touched set is empty and the FULL L0 layer runs (verified: ci/lib.sh
+#     load_touched_requirements) — this check runs. An edit to clusters/* maps to
+#     R-ENV-02, which this check carries, so a cluster-vars value change also selects it.
+#     A change that touches standup.sh ALONGSIDE some unrelated mapped path (say
+#     platform/cilium/) would scope the run away from this check; closing that needs a
+#     `bootstrap/*` entry in the path map, which is not this check's file to edit.

+# L0 static check (offline, no cluster) — prod-baremetal-not-dev-surface
+# Serves: R-ENV-03 ("prod is a 3× mini-PC bare-metal k3s cluster with local storage; it
+#         MUST NOT be an active development surface until the roadmap declares it ready."
+#         — spec docs/00-vision-and-scope.md. Detail in docs/02: prod substrate "3× mini-PC
+#         bare metal", "3 physical nodes", storage "local SSD/NVMe presented to Longhorn",
+#         "For prod bare-metal, the *same* Ansible bootstrap runs; only the machine-creation
+#         step differs", and "**Never develop against prod.** Prod hardware is a target, not
+#         a sandbox (R-ENV-03)". The roadmap gate is roadmap/phases.md Phase 7: entry
+#         "operator declares prod hardware ready"; note "Do not begin building on prod
+#         hardware before this phase is explicitly opened".)
+#
+# HOW A "MUST NOT" IS MADE TESTABLE
+# --------------------------------
+# The second clause is a governance rule, and the same discipline applies as to R-TEST-06
+# (tests/l0-static/spec-immutability-enforced): "nobody developed against prod today"
+# cannot be observed, but the PROPERTY THAT MAKES DEVELOPING AGAINST PROD IMPOSSIBLE can
+# be. In this repo that property is structural — prod receives the base configuration plus
+# environment-scoped overrides and NOTHING ELSE, so there is no place to put prod-only work
+# even if someone wanted to. This check asserts that, together with the first clause's
+# authored facts (three nodes, no VM IaC behind them, node-local storage, the same
+# bootstrap code as dev).
+#
+# The first clause's HARDWARE facts (that the three machines really are mini-PCs, really
+# are bare metal, really hold local NVMe) are operator-attested, not machine-checkable —
+# see the gap list. What IS checkable is that the repository describes prod that way and
+# that no IaC creates prod nodes as virtual machines.
+#
+# GIVEN the repository as git tracks it (plus the read-only spec repo when mounted),
+# WHEN  the prod inventory, the prod overlay, the IaC module and the roadmap record are
+#       inspected — and, where offline execution is possible, the provisioning chain is
+#       actually retargeted at prod with `--list-hosts`,
+# THEN  (1) prod resolves to EXACTLY THREE nodes, reached directly on their own sshd
+#           (no NAT indirection, i.e. real machines on the LAN);
+#       (2) NO IaC resource creates any prod node: the VM module's generated node names are
+#           disjoint from the prod host set and no prod hostname appears anywhere under
+#           infra/tofu — prod is imaged by the operator (docs/02 stage 1), not instantiated;
+#       (3) prod's storage is NODE-LOCAL: the Longhorn data path for prod is an absolute
+#           local path, and the replica count equals the node count (one replica per node's
+#           own disk). A distinct bulk/media tier is explicitly permitted (R-STATE-04) and
+#           is not counted against this;
+#       (4) prod runs THE SAME bootstrap code as dev: the same playbooks/roles, retargeted
+#           by variables only — every prod group_vars key is an existing role/global
+#           variable (an invented prod-only knob would be a fork), and no prod-only role
+#           or playbook exists;
+#       (5) prod is NOT a development surface: clusters/prod carries only the base plus
+#           sync.yaml, every patch it applies targets an ENVIRONMENT-SCOPED object
+#           (cluster-vars, a Flux Kustomization's sops decryption, or the Git source),
+#           prod's Git ref is the SAME ref dev tracks (no prod-only branch to develop on),
+#           and no prod-only manifest exists anywhere in the rendered configuration — a file
+#           whose NAME carries the environment token is excused ONLY when the tree proves it
+#           is an OVERLAY-SELECTED half that every environment applies (see the four
+#           conditions at "THE ONE STRUCTURAL EXCEPTION" below); anything else still fails;
+#       (6) prod artifacts exist only WITH a declaration of readiness: the spec roadmap
+#           carries the phase that opens prod build (checked when the spec repo is mounted),
+#           and the repository records that the operator opened it.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
+#   - The HARDWARE. That the three nodes are mini-PCs, are bare metal, and present local
+#     SSD/NVMe is operator-attested in infra/PROD-STANDUP.md / PROD-PROVISIONING.md; the
+#     node-health and BIOS surveys that establish it write to gitignored artifacts, so
+#     nothing tracked can be asserted against. Cluster-side, the Kubernetes API exposes no
+#     "am I virtual" fact either — a bare-metal check would need a privileged host-path
+#     probe of DMI data, which is a heavier and more invasive test than the claim warrants.
+#   - The LIVE prod cluster's shape (three Ready nodes, all control-plane+etcd, Longhorn
+#     disks at the local path). That is cluster state and belongs to R-PLAT-01's
+#     (currently uncovered) HA test; asserting it here would also make this test
+#     environment-specific, since the same suite must pass against dev.
+#   - That prod's HISTORY contains no development. This is the working tree at HEAD.
+#   - Whether the roadmap SHOULD have opened prod (the entry-gate judgement). Only that
+#     prod work is accompanied by the operator's recorded declaration.

+# ------------------------------------------------------------------
+# A filename carrying an environment token is a HEURISTIC for the harm R-ENV-03 names
+# (content only prod runs, in a path every environment renders). It is not the harm
+# itself. There is exactly one shape where a `-prod` name is the OPPOSITE of a prod-only
+# fork: a credential that is TWO Secret objects, BOTH applied to BOTH clusters as base
+# resources, where a cluster-vars knob decides only which one the shared consumer
+# REFERENCES (clusters/base/cluster-vars.yaml, BACKUP_CREDENTIALS_SUFFIX: dev backs up to
+# MinIO, prod to Cloudflare R2, and one shared Secret meant either environment's rotation
+# broke the other). Nothing is forked: every environment renders the identical manifests
+# and the identical object set, which is precisely the R-ENV-02 contract.
+#
+# So the exception is not a path allowlist — it is the PROPERTY that makes that shape
+# safe, asserted from the tree, and a file is excused ONLY when all of it holds:
+#
+#   (A) it declares nothing but Secrets whose names end in the environment suffix — the
+#       only kind of object this repo has a selection mechanism for;
+#   (1) it is listed in its own directory's kustomization.yaml, so EVERY environment
+#       applies it, and every environment's value of the selector resolves to an object
+#       that some resource of that same kustomization declares (same namespace) — no
+#       environment is left selecting a Secret that does not exist;
+#   (2) nothing references the suffixed name literally: every reference is a substituted
+#       expression `<base-name>${VAR}`, and the suffixed FILE is named only by the
+#       kustomization that applies it — so no shared manifest hardcodes prod's half;
+#   (3) that VAR is defined for the base AND for every overlay (StrictPostBuildSubstitutions
+#       fails on an UNDEFINED variable, so an overlay that forgot it would break that
+#       cluster's reconciliation), and prod's value is the one that selects THIS file.
+#
+# References are read from PARSED YAML VALUES, never from raw text: the mechanism is
+# documented by name in comments beside the resources (cluster-vars says so explicitly),
+# and a name in a comment references nothing. Anything that fails any condition still

+#
+# R-TLS-02 is one adverbial clause plus three runtime verbs. This test asserts the
+# clause — "without manual steps" — which in a GitOps platform is a property of the
+# REPOSITORY: a human step in the certificate path leaves evidence in git (committed
+# cert material, a Gateway serving a Secret nothing declares, an issuer with no
+# automated solver, a credential never delivered, auto-approval switched off, or CRs
+# nothing reconciles). The three verbs are observed by the companion L2 test.
+#
+# ENVIRONMENT-AGNOSTIC (R-ENV-02): the issuer a Certificate names is `${ACME_CLUSTER_ISSUER}`,
+# so the check resolves it against the BASE cluster-vars default AND every overlay's value and
+# requires each resolved issuer to exist. dev's issuer and prod's issuer are both verified from
+# one authored assertion, with no hostname, address or environment name written down.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  every serving-TLS reference, Certificate, Issuer and the cert-manager release
+#       is inspected offline,
+# THEN  every Gateway listener that terminates TLS serves a Secret a tracked Certificate

+#       issuer resolves — in EVERY environment — to a tracked ACME issuer with an

+# L0 static check (offline, no cluster) — tls-lifecycle-automated
+# Serves: R-TLS-02 ("Certificates MUST be automatically **issued, renewed, and revoked**
+#         without manual steps." — spec docs/00-vision-and-scope.md; mechanism in
+#         docs/08-tls-and-certificates.md, ADR-0006.)
+#
+# WHICH CLAUSE THIS LAYER CAN PROVE — AND WHICH IT CANNOT
+# ------------------------------------------------------
+# R-TLS-02 has one adverbial clause ("without manual steps") and three verbs
+# ("issued", "renewed", "revoked"). In a GitOps platform the *without manual steps*
+# clause IS a repository property, and it is the half that can be proven with no
+# cluster: if a human had to mint, install, or approve a serving certificate, the
+# evidence of that human step would be IN THE REPO — a committed `tls.crt`, a Gateway
+# pointing at a Secret nothing declares, an issuer that no automated solver can
+# satisfy, a per-cert credential handed over out of band, or an admission path that
+# waits for a manual CertificateRequest approval. This check asserts that none of
+# those exist and that the automated path is completely wired instead.
+#
+# The three VERBS are runtime events. They are asserted by the companion L2 test
+# (conformance/tests/l2-behavioral/cert-lifecycle-automated), which observes an
+# issuance, an unattended renewal, and the withdrawal of a removed certificate. This
+# check does NOT claim them; see "WHAT THIS DOES *NOT* PROVE" below.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  every serving-TLS reference, Certificate, Issuer and the cert-manager release
+#       are inspected offline,
+# THEN  (1) at least one cert-manager `Certificate` is authored (vacuity floor: a repo
+#           with no Certificate cannot pass this check by having nothing to check);
+#       (2) every Gateway HTTPS listener that TERMINATES TLS references ONLY Secrets
+#           that a tracked Certificate declares as its `secretName` — so the serving
+#           credential is produced by the controller, never dropped in by hand;
+#       (3) NO certificate material is tracked anywhere: no Secret manifest of type
+#           kubernetes.io/tls, no tls.crt/tls.key/ca.crt key in any committed Secret
+#           (plain OR SOPS-encrypted), and no PEM certificate body in any tracked
+#           YAML — i.e. issuance is not, and cannot silently become, a human step;
+#       (4) every Certificate's `issuerRef` resolves to a TRACKED issuer IN EVERY
+#           ENVIRONMENT — the `${ACME_CLUSTER_ISSUER}` token is resolved against the
+#           base cluster-vars default AND every overlay's value, so an environment
+#           whose issuer does not exist is caught here rather than at prod bring-up;
+#       (5) every issuer so referenced is an ACME issuer with a NON-EMPTY solver list
+#           whose every solver is an automated challenge type (dns01 / http01) — the
+#           same code path serves issuance AND renewal, so a solver a human must
+#           complete would defeat both;
+#       (6) each dns01 solver's provider credential is referenced BY NAME and that
+#           Secret is delivered SOPS-encrypted from git via a kustomization — the
+#           operator's one-time token hand-off (docs/08 OQ-4), never a per-cert step;
+#       (7) cert-manager's automatic CertificateRequest approval is NOT disabled
+#           (`disableAutoApproval`), and any `approveSignerNames` narrowing still
+#           covers the ClusterIssuers actually used — a request that waits for a
+#           human approver is the definition of a manual step;
+#       (8) the whole chain is reconciled from git — cert-manager's HelmRelease, the
+#           ClusterIssuers and the Certificate are each included in a kustomization
+#           that a Flux Kustomization renders — so a deleted Certificate is
+#           re-created and re-issued with no human action;
+#       (9) no Certificate defeats renewal arithmetically (`renewBefore` >= `duration`
+#           would mean the renewal instant never arrives).
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
+#   - ISSUED: that an issuance actually happens. Asserted at L2 (step 2 of
+#     l2-behavioral/cert-lifecycle-automated) and, for the real ACME/DNS-01 path,
+#     evidenced by l2-behavioral/trusted-tls serving a publicly-trusted cert.
+#   - RENEWED: that a renewal actually happens unattended. docs/08's acceptance gate
+#     is explicit that this must be "observed across a renewal" — L2 step 3 does that
+#     by fast-forwarding a certificate's renewal window; nothing static can.
+#   - REVOKED: NOT PROVEN AT ANY LAYER TODAY, and not asserted here. Two distinct
+#     readings, neither established: (a) ACME revocation — cert-manager does not
+#     revoke certificates at all, so no repo state could show it; (b) the spec's own
+#     reading in docs/08 ("removing/rotating a certificate is a declarative change")
+#     — withdrawal of a REMOVED certificate's serving material requires cert-manager's
+#     `enableCertificateOwnerRef`, which the tracked HelmRelease does NOT set (chart
+#     default false). L2 step 4 asserts the withdrawal behaviour and is expected to
+#     FAIL until that knob is set; escalated to the PM rather than softened (R-TEST-06).
+#   - That the tracked Certificate is the one the live Gateway is actually serving
+#     (cluster state), or that the ACME account/DNS credential is still valid.
+#   - Certificate EXPIRY ALERTING, which docs/08 delegates to R-OBS-04 (see
+#     l3-fault-injection/alerting).

+#          docs/08 acceptance gate — "Certificates renew automatically ahead of expiry
+#          with no manual step (**observed across a renewal**)."
+# Impl:    platform/cert-manager/**, platform/gateway/wildcard-certificate.yaml.
+# Sibling: tests/l0-static/tls-lifecycle-automated proves the "without manual steps"
+#          clause statically (in the merge gate). This test observes the three VERBS.
+#
+# ENVIRONMENT-AGNOSTIC (R-ENV-02): NOTHING about either environment is written down. The
+# serving certificate is DISCOVERED — find the Gateway whose listener terminates TLS, follow
+# its certificateRefs Secret, and read that Secret's `cert-manager.io/certificate-name`
+# annotation to reach the Certificate. No hostname, no namespace list, no issuer name, no
+# address: dev proves dev's cert and prod proves prod's from the same authored assertions.
+#
+# GIVEN cert-manager reconciled by Flux and a Gateway terminating TLS,
+# WHEN  the serving Certificate's provenance and renewal schedule are read, and a NEW
+#       Certificate is then requested, left to renew itself, and removed,
+# THEN  1. the serving credential was produced by the CONTROLLER, not a human: its
+#          Secret carries cert-manager's certificate-name annotation, its
+#          CertificateRequest was submitted by cert-manager's own ServiceAccount and
+#          was APPROVED automatically, and its issuer is a Ready ACME ClusterIssuer;
+#       2. an unattended RENEWAL IS SCHEDULED: status.renewalTime is in the future and
+#          strictly before status.notAfter, so no human is in the renewal path;
+#       3. ISSUED — a newly declared Certificate becomes Ready and its Secret appears
+#          with certificate material, with no step between declaring and having it;
+#       4. RENEWED — that certificate, given a renewal window that opens one minute
+#          after issuance, REISSUES ITSELF at least twice (status.revision >= 3) and
+#          the serving bytes actually change, with no human action. This is docs/08's
+#          "observed across a renewal", fast-forwarded;
+#       5. REMOVED/REVOKED — deleting the Certificate withdraws its serving material.
+#
+# WHY A HERMETIC SELF-SIGNED ISSUER FOR STEPS 3-5, AND WHAT THAT COSTS
+# -------------------------------------------------------------------
+# Steps 3-5 need a certificate lifecycle that completes in minutes and repeats on every
+# run. Driving that through the real ACME issuer would fire a public Let's Encrypt order
+# (and a Cloudflare _acme-challenge write) per conformance run, burning issuance rate
+# limits for evidence that is not about ACME: cert-manager's renewal scheduler and
+# ownership logic are issuer-independent. So steps 3-5 use a `selfSigned` Issuer created
+# in this test's OWN namespace, and the ACME/DNS-01 path is proven elsewhere — step 1-2
+# read the REAL wildcard certificate the Gateway serves, and l2-behavioral/trusted-tls
+# proves a publicly-trusted LE certificate is actually served (R-TLS-01/03).
+# STATED PLAINLY: steps 3-5 do NOT prove the ACME order path renews; they prove the
+# CONTROLLER's issue/renew/withdraw automation runs unattended in this cluster, while
+# steps 1-2 prove the real serving certificate is on exactly that automated path.
+#
+# STATUS: RUNNABLE, NOT YET EXECUTED. Steps 1-2 are read-only. Steps 3-5 CREATE an
+# Issuer/Certificate (and DELETE the Certificate they created) inside chainsaw's
+# per-test namespace — the same class of mutation every other L2 test here performs,
+# self-cleaning via namespace teardown, touching no platform object. WS-TEST authored
+# them against live dev/prod read-only inspection under an explicit instruction not to
+# mutate either cluster, so THE MUTATING STEPS HAVE NOT BEEN RUN. Nothing about the
+# suite gates on them: ci/conformance.sh only runs L2/L3 when CLUSTER_AVAILABLE=true.
+#
+# EXPECTED FAILURE, DELIBERATELY NOT SOFTENED (R-TEST-06)
+# ------------------------------------------------------
+# Step 5 WILL FAIL as the platform is authored today. cert-manager only garbage-collects
+# a Certificate's Secret when the controller runs with `enableCertificateOwnerRef: true`;
+# platform/cert-manager/helmrelease.yaml does not set it (chart default false), and the
+# live wildcard Secret on both clusters has NO ownerReferences (verified read-only,
+# 2026-09-05). So a removed Certificate leaves its credential in place, and "revoked
+# without manual steps" does not hold. That is a finding about the platform, not a
+# defect in this test: the assertion stays as the requirement reads and is escalated to
+# the PM. (ACME revocation proper is not implemented by cert-manager at all.)
+#
+# KNOWN, DELIBERATE GAPS (this test claims none of these):
+#   * Not proven: that the CA would refuse a revoked certificate — there is no
+#     revocation request to make, so nothing observable exists to assert.
+#   * Not proven: renewal of the REAL wildcard cert (its window opens 30 days before a
+#     90-day expiry; a conformance run cannot wait, and forcing it would rotate the
+#     platform's serving credential). Step 2 asserts the schedule; step 4 asserts the
+#     mechanism that will act on it.
+#   * Not proven: certificate expiry ALERTING — docs/08 delegates that to R-OBS-04
+#     (l3-fault-injection/alerting).

+#          in-cluster `vpn` path").

+#          docs/03 §"VPN egress model": "**Default is the WAN; the VPN is strictly opt-in.**
+#          Every pod — and the nodes themselves — egress the local/private WAN by default and
+#          **never** the VPN. Only services labeled `egress-class=vpn` are steered to the
+#          tunnel"; and the tunnel "is **split-tunnel**: ... only what Cilium points at `tun0`
+#          uses the VPN."
+#
+# WHAT THIS PROVES THAT tests/l2-behavioral/egress-class DOES NOT
+# --------------------------------------------------------------
+# That test (R-NET-05/07) compares two LABELLED pods — `internet` vs `vpn` — and shows their
+# public IPs differ, then flips a label. Both of its pods declared a class, so it says nothing
+# about the case R-NET-04 actually turns on: a pod that NO routing rule selects. This test adds
+# that pod, and asserts the two claims that make a rule-selected path set complete:
+#
+#   TOTALITY   — an UNLABELLED pod egresses the WAN, i.e. the same public IP as the
+#                explicitly-`internet` pod. Absence of a matching rule IS a path, and it is
+#                the local one. If the steering rule ever widened (an empty selector, a
+#                matchExpression, a second rule), this pod's IP would move to the tunnel and
+#                this assertion is what would notice.
+#   COEXISTENCE — the WAN path and the VPN path are live AT THE SAME TIME, observed in one
+#                pass: three pods, two distinct public IPs. "Multiple egress paths" is a
+#                simultaneity claim, not a claim that one switch has two positions.
+#   PER-DESTINATION SELECTION — the vpn-class pod still reaches an in-cluster/RFC1918
+#                destination over the LOCAL path while its public traffic is tunnelled. The
+#                tunnel is destination-scoped (excludedCIDRs), not a default route, so ONE pod
+#                uses BOTH paths at once.
+#
+# ENVIRONMENT-AGNOSTIC (R-ENV-02): no address, hostname or range appears. Every assertion is a
+# RELATION between observed values (equal / not-equal), so it holds against dev and prod alike
+# and survives the WAN or the VPN provider rotating addresses.
+#
+# GIVEN one unlabelled, one `internet`-class and one `vpn`-class pod — the same workload three
+#       times, differing only in the class they declare (or do not),
+# WHEN  each asks an external echo for the public IP it egressed from, and the vpn-class pod
+#       also resolves a name through the in-cluster resolver,
+# THEN  the unlabelled pod's public IP EQUALS the internet-class pod's (the default route out
+#       is the WAN, and the VPN is strictly opt-in);
+# AND   the vpn-class pod's public IP DIFFERS from both (a second, simultaneously-live path);
+# AND   the vpn-class pod still resolves in-cluster (its private-destination traffic was not
+#       swallowed by the tunnel), so the same pod is using both paths at once.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
+#   - THAT NO OTHER RULE EXISTS. Three pods cannot enumerate a rule set. That exactly one
+#     steering rule is authored, that it selects only the vpn class, that no `ip rule` is
+#     unscoped and no nftables DROP unqualified is the L0 half, in
+#     tests/l0-static/egress-paths-selected-by-rules (same requirement label).
+#   - WHICH INTERFACE the packets left by. The observation is the public IP an external echo
+#     reports; it distinguishes the paths without naming them. Asserting "out tun0" would need
+#     host-level datapath inspection (Hubble/tcpdump on the gateway node), which no test in
+#     this suite does.
+#   - THE KILL-SWITCH. Tunnel-down behaviour is R-NET-06's, at L3 (vpn-killswitch): `vpn`
+#     fails closed. Its mirror — that `internet` is never blackholed — is asserted statically
+#     by the L0 half, not here.
+#   - NODE traffic. docs/03 also says "the nodes themselves" egress the WAN by default. That
+#     is a host-level fact this test cannot see from a pod.
+#   - EXTERNAL DEPENDENCY, stated plainly: the public-IP echo (api.ipify.org) is off-cluster,
+#     so a WAN outage or the echo being down fails this test. That is the same dependency
+#     tests/l2-behavioral/egress-class already carries; the alternative — trusting the
+#     cluster's own account of which path it used — would not be a behavioural test at all.
+#

+#
+# WHY L2 — AND WHAT L0 ALREADY DID
+# --------------------------------
+# tests/l0-static/ha-control-plane-as-code (same requirement label) proves the AUTHORED
+# half offline: the repo builds a 3-server embedded-etcd control plane in both environments,
+# one founder, no external datastore, a leader-elected control-plane-only VIP in the serving
+# cert's SANs. It cannot prove that any of it is TRUE OF A RUNNING CLUSTER — an inventory
+# entry is not a node, and a templated DaemonSet is not a floating VIP. That is this test:
+# every assertion below is read from the cluster the suite is pointed at.
+#
+# ENVIRONMENT-AGNOSTIC (R-ENV-02): no address, hostname, node count or range is written
+# here. The expected node count comes from the cluster's OWN declared identity
+# (flux-system/cluster-vars CLUSTER_ENV, via a test-level chainsaw binding — the same
+# ConfigMap Flux substitutes from); the control-plane VIP is read out of the kube-vip
+# DaemonSet the cluster is actually running; the server addresses come from the Node
+# objects; and the LoadBalancer pool the VIP must stay outside of is read from cluster-vars
+# too. R-PLAT-01 itself distinguishes prod from dev/test ("3 nodes ... in prod; dev/test MAY
+# run fewer"), so the assertion is necessarily environment-AWARE — but it takes the
+# environment from the cluster, never from a flag or a literal, which is precisely the
+# mechanism the tests/README.md convention prescribes.
+#
+# GIVEN the cluster this suite is pointed at,
+# WHEN  its Nodes, its kube-vip DaemonSet and its kube-apiserver endpoints are inspected,
+# THEN  DISTRO:  every node's kubelet is a k3s build (`+k3s`) — the distro really is k3s;
+#       SERVERS: every Ready node is BOTH control-plane AND etcd (the converged 3-node
+#                topology docs/02 fixes — no agent-only node, no control-plane-only node),
+#                the count is ODD and quorum-capable (tolerates >= 1 loss), and it is
+#                EXACTLY three when the cluster declares itself prod;
+#       ETCD:    every one of those nodes is a REGISTERED embedded-etcd member (k3s stamps
+#                `etcd.k3s.cattle.io/node-name` on a node that joined the etcd cluster), so
+#                the datastore is embedded and replicated across all of them;
+#       VIP:     kube-vip is Ready on EVERY control-plane node, is control-plane-only
+#                (svc_enable=false — it must not contend with Cilium LB-IPAM for ARP), and
+#                the address it floats is neither a node address, nor the ingress Gateway
+#                VIP, nor inside the Cilium LoadBalancer pool;
+#       ENDPOINT: the kube-apiserver answers `/readyz` THROUGH THAT VIP over TLS that
+#                validates against the cluster CA for the VIP itself — i.e. the VIP really
+#                fronts the API and the serving cert really carries it;
+#       EVERY SERVER SERVES: the apiserver also answers `/readyz` on EVERY server's own
+#                address, again with a CA-valid cert for that address. This is the assertion
+#                that separates a real HA control plane from one server plus two joiners:
+#                if only the founder ran an apiserver, the other addresses would refuse.
+#
+# THE PROBE RUNS IN-CLUSTER, DELIBERATELY. An earlier draft dialled the VIP and the node
+# addresses from the RUNNER. That works from a host on the node LAN (verified against prod)
+# and FAILS against dev, whose nodes sit behind a NAT the runner reaches only via a
+# forwarded port — i.e. it would have made the test a property of where it was launched
+# from. A Job on the cluster is on the node network in both environments, so the probe is
+# the same probe everywhere. The Job is created imperatively (kubectl heredoc) rather than

+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
+#   - FAILOVER / SURVIVAL. Nothing here removes a node. That etcd keeps quorum, that the VIP
+#     migrates, and that the API stays reachable when a server dies is an L3 fault-injection
+#     claim and is proven NOWHERE in this suite yet (tests/l3-fault-injection/node-loss
+#     drains a node for R-STATE-02's data-availability claim and asserts nothing about the
+#     control plane). This is the largest remaining R-PLAT-01 gap.
+#   - THE NEXT environment. That the repo would build an HA control plane again is the L0
+#     half (tests/l0-static/ha-control-plane-as-code).
+#   - "PRODUCTION-GRADE" as a capacity/performance judgement (operator's, docs/02 + §2 of
+#     infra/PROD-PROVISIONING.md).
+#   - THAT THE RUNNING cilium-agents ACTUALLY DIAL THIS VIP. As of 2026-09-06 the repository
+#     authors `K3S_API_HOST` = the control-plane VIP in both environments (asserted at L0 by
+#     tests/l0-static/ha-control-plane-as-code, on both sides of the [parity] contract), but
+#     this test does not read the agents' live `KUBERNETES_SERVICE_HOST`. Until the operator
+#     applies that change the LIVE agents still carry the PRIMARY NODE's address — measured
+#     2026-09-06: all three prod agents on 192.168.2.10 while kube-vip held 192.168.2.9. An
+#     in-cluster assertion on the agents' endpoint belongs here and is NOT yet written; it is
+#     the obvious follow-up once the change is applied and would catch drift the L0 check
+#     cannot see (a hand-edited DaemonSet, a Helm value overridden out of band).
+#   - etcd health beyond membership registration (raft leader, DB size, alarms) — k3s exposes
+#     it only on the node-local etcd metrics port, which is not reachable through the
+#     Kubernetes API this test is allowed to use.
+#
+# CLEANUP: the probe Job lives in chainsaw's per-test namespace and is deleted with it
+# (config/chainsaw-config.yaml skipDelete: false). Everything else is read-only: this test
+# creates nothing outside its own namespace and mutates no platform object.

+# Impl: platform/keycloak/client-secret-reconciler.yaml (the CronJob + its script).
+#
+# WHY THIS TEST EXISTS
+# --------------------
+# The KeycloakRealmImport resolves each confidential client's secret from a `(env:NAME)`
+# placeholder mapped to a key of the SOPS-encrypted keycloak-realm-clients Secret. When
+# the Keycloak Operator cannot resolve a placeholder it stores the LITERAL placeholder
+# text as the client secret AND THE IMPORT JOB STILL REPORTS SUCCESS; the CR then rests
+# at Done=True / Started=False and never re-runs. Measured 2026-09-06: prod had all 12
+# clients holding the literal placeholder — every OIDC login on the cluster failed with
+# "Invalid client or Invalid client credentials" — and dev had one (oauth2-proxy), whose
+# Secret key was added after dev's import had already completed.
+#
+# Every SIGNAL the cluster offered was green: the import Job succeeded, the CR read
+# Done=True, the Keycloak pods were healthy, and the existing keycloak-config-as-code
+# test (which asserts Done=True) PASSED throughout. The only observable was a human
+# failing to log in. This test is that observable, automated: it compares STORED against
+# DECLARED for every client and fails on any difference, so the class cannot sit
+# undetected for months again.
+#
+# GIVEN the `homelab` realm and the SOPS-encrypted keycloak-realm-clients Secret,
+# WHEN  the reconciler's script is run in --audit mode (READ-ONLY: it cannot write, and
+#       its endpoint allow-list makes users/groups/roles unreachable),
+#   ->  THEN every declared client's stored secret matches git, and none holds an
+#       unresolved import placeholder. Emits KEYCLOAK_CLIENT_SECRETS_AUDIT_OK.
+#
+# WHY IT RUNS THE SHIPPED SCRIPT rather than re-implementing the comparison: a detector
+# that duplicates the healer's logic drifts from it. This audits with the same code, in
+# the same mode the L0 gate selftests, so a passing audit is evidence about the healer
+# too. It runs as a Job IN the keycloak namespace (not in the ephemeral chainsaw
+# namespace) because the desired state is the mounted keycloak-realm-clients Secret and
+# the admin credential is keycloak-admin-credentials — both namespace-local, which is
+# also why neither this Job nor the CronJob needs any Kubernetes API access.
+#
+# chainsaw v0.2.12: Job + status assert; the leftover-Job delete keeps a re-run from
+# colliding with an immutable Job left by a previous failure.

+# Bulk NFS storage — the media library and the legacy Nextcloud archive
+
+The operator-facing companion to the `class: bulk` storage entries in `catalog/{plex,sonarr,radarr,nextcloud}.yaml`.
+Everything here was **measured** on the storage host on 2026-09-07, over read-only SSH; nothing is
+assumed. It resolves the long-standing **OQ-2** stub (`platform/longhorn/storageclasses.yaml`) for the
+case that actually exists here — attaching datasets that already hold data — and leaves dynamic bulk
+provisioning unimplemented, because nothing needs it.
+
+---
+
+## 1. The storage host, and why prod cannot reach it
+
+The bulk data lives on the **Proxmox host's ZFS pool**. That host has exactly one interface:
+
+```
+vmbr0  192.168.1.9/24        default via 192.168.1.1   (pfSense LAN)
+```
+
+| | nodes | reaches 192.168.1.9? |
+|---|---|---|
+| **dev** | 192.168.1.40 / .41 / .42 | **Yes** — same L2 segment, and it already holds an NFS export from this host (`/mnt/Storage/k8s-volumes`, in `/etc/exports`) |
+| **prod** | 192.168.2.10 / .11 / .12 | **No** — 192.168.2.0/24 is pfSense's **WAN**. Ports 22 and 8006 answer only because pfSense port-forwards them via 192.168.2.102. 2049 and 111 do not. |
+
+Opening the storage path for prod is a **pending operator decision**. Its two candidate outcomes give
+different values for the `BULK_NFS_SERVER` cluster-var:
+
+| outcome | `BULK_NFS_SERVER` for prod |
+|---|---|
+| port-forward `192.168.2.102:2049` → `192.168.1.9:2049` | `192.168.2.102` |
+| a WAN→LAN route to 192.168.1.0/24 | `192.168.1.9` |
+
+Until it lands, `clusters/prod` holds `TBD-PROD-BULK-NFS-SERVER`. **See §7 for why that placeholder
+behaves differently from the repo's other ones.**
+
+### It only needs ONE port
+
+The PVs mount `nfsvers=4.1`. **NFSv4 carries mount and lock in-protocol**, so the only thing that
+must be reachable is **tcp/2049** — no rpcbind/111, no mountd, no statd. NFSv3 would have needed
+four ports, three of them on ephemeral numbers, which is a materially worse firewall story. The
+server advertises `+3 +4 +4.1 +4.2` (`/proc/fs/nfsd/versions`), so v4.1 is available and is the
+conservative floor.
+
+### The export's client list is the SAME under both outcomes — measured, not assumed
+
+**pfSense DNATs the existing port-forward WITHOUT source NAT.** Connecting from this workstation
+(192.168.2.132) to `192.168.2.102:22`, the storage host logged the peer as `192.168.2.132`:
+
+```
+SSH_CONNECTION=192.168.2.132 39768 192.168.1.9 22
+ss -tn  ->  192.168.1.9:22   192.168.2.132:39768
+```
+
+The original WAN-side source address survives the translation (return traffic finds its way back via
+the host's default route, 192.168.1.1). So under **either** outcome the NFS server will see prod's
+**real** node addresses — 192.168.2.10/.11/.12 — and the `sharenfs` change in §5 is the same either
+way. **It does not have to wait for the routing decision.**

+```
+
+**The single most important fact about this layout: `downloads/` is a SIBLING of `tv/` and `movies/`
+inside the same dataset.** Sonarr's import source and its library are on one filesystem on the
+server, and so are Radarr's. That is what makes hardlinked / atomically-renamed imports possible at
+all — and §4 is about not throwing it away on the client side.
+
+Note the download client's completed folders are already named `radarr` and `tv-sonarr`, i.e. this
+tree has been driven by an arr stack for a long time. The k3s arrs are joining an existing layout,
+not defining one.
+
+### `Storage/nextcloud` → `/mnt/Storage/nextcloud` — 270 G used
+
+```

+    └── config_backup/   267 G     drwxr-xr-x  1000:3000
+```
+
+**There is no `data/` directory.** 99% of the dataset is `config_backup`. This is the old, non-k3s
+Nextcloud's configuration plus a backup blob — an **archive**, not a live user-data tree. That is
+why it is mounted read-only; see §6.
+
+---
+
+## 3. What each app mounts, and why
+
+| app | export | mountPath | subPath | mode | access mode |
+|---|---|---|---|---|---|
+| plex | `/mnt/Storage/plex` | `/media` | — | **ro** | ReadOnlyMany |
+| sonarr | `/mnt/Storage/plex` | `/media` | — | rw | ReadWriteMany |
+| radarr | `/mnt/Storage/plex` | `/media` | — | rw | ReadWriteMany |
+| nextcloud | `/mnt/Storage/nextcloud` | `/mnt/legacy-nextcloud` | `nextcloud` | **ro** | ReadOnlyMany |
+
+In-app paths that follow: Plex libraries at `/media/movies`, `/media/tv`, `/media/photos`; Sonarr
+Root Folder `/media/tv`; Radarr Root Folder `/media/movies`; both importing from
+`/media/downloads/complete/{tv-sonarr,radarr}`.
+
+**All three media consumers use the identical mountPath on purpose.** When qbittorrent is eventually
+given the same export (it is not in this change), the arrs and the download client will already agree
+on absolute paths, which is the second precondition for hardlinked imports — otherwise every import
+needs a Remote Path Mapping and quietly falls back to copying when one is missing.
+
+**`/media` and not `/data`, and that is not cosmetic.** The arrs' Longhorn config PVC renders at the
+renderer default `/data/config`. A media mount at `/data` would be mounted **over** it and mask the
+config volume entirely. See §8 for the separate latent bug that discovery exposed.
+
+---
+
+## 4. Why the arrs mount the export ROOT, not two subPaths
+
+This is the design decision most likely to be "simplified" later by someone who has not read this.
+
+Sonarr and Radarr import a finished download into the library by **hardlinking** it (preserving the
+seeding copy) or by an **atomic rename**. Both are same-filesystem operations, and **to the kernel,
+"same filesystem" means "same mount."**
+
+The tempting narrower shape is two subPath volumes — `subPath: tv` and `subPath: downloads`. Those
+are **two separate mounts** of the same export. `link()` across them returns **EXDEV** no matter that
+the server knows perfectly well they are one dataset. Sonarr does not fail loudly at that: it
+degrades to copy-then-delete. Every import then rewrites the entire file over NFS and destroys the
+seeding copy. The symptom is "imports are slow and my ratio is gone", weeks later.
+
+The smallest subtree containing both `tv/` and `downloads/` **is the export root**. So the root mount
+is the *minimal* mount that preserves hardlinks: least privilege bounded below by a hard requirement,
+not a shortcut.
+
+The cost is stated rather than hidden: Sonarr can also write `/media/movies` and Radarr `/media/tv`.
+Narrowing that would cost hardlinks, which is the worse trade.
+
+---
+
+## 5. The export change the operator must apply — STRICTLY ADDITIVE
+
+**Do not apply this from the repo.** It is an operator step on the storage host, recorded here so the
+exact value is reviewable. The existing consumers **must keep working**: 192.168.1.6, 10.123.1.10 and
+192.168.1.18 on the media tree, and 192.168.1.6 and 192.168.1.5 on the Nextcloud dataset, are the
+live non-k3s prod stack.
+
+Current values (`zfs get sharenfs Storage`):
+
+```
+Storage/plex       rw=@192.168.1.6:@10.123.1.10:@192.168.1.18,no_subtree_check,no_root_squash
+Storage/nextcloud  rw=@192.168.1.6:@192.168.1.5,no_subtree_check,no_root_squash
+```
+
+### `Storage/plex` — append the six k3s node addresses to the existing `rw=` list
+
+```sh
+zfs set sharenfs='rw=@192.168.1.6:@10.123.1.10:@192.168.1.18:@192.168.1.40:@192.168.1.41:@192.168.1.42:@192.168.2.10:@192.168.2.11:@192.168.2.12,no_subtree_check,no_root_squash' Storage/plex
+```
+
+Every pre-existing host is preserved verbatim and no option changes; only clients are added.
+
+### `Storage/nextcloud` — add the k3s nodes to a **`ro=`** list, not to `rw=`
+
+```sh
+zfs set sharenfs='rw=@192.168.1.6:@192.168.1.5,ro=@192.168.1.40:@192.168.1.41:@192.168.1.42:@192.168.2.10:@192.168.2.11:@192.168.2.12,no_subtree_check,no_root_squash' Storage/nextcloud
+```
+
+This is the one place read-only can be enforced **server-side**, and it is worth taking: only
+Nextcloud consumes this dataset from k3s, so the export itself can refuse writes. Even a
+misconfigured client cannot then damage the archive.
+
+**The media tree cannot get the same treatment.** Plex is read-only and the arrs are read-write, but
+all three may be scheduled on any node, so the server sees the same source addresses for all of
+them and cannot distinguish the reader from the writers. **Plex's read-only posture is therefore a
+client-side guarantee** (`spec.nfs.readOnly: true` on `plex-media`, plus the volumeMount flag) — an
+honest limitation, not an oversight. If it ever needs to be server-enforced, the lever is a
+dedicated node pool for Plex, which is a much larger change.
+
+Per-node addresses rather than `@192.168.2.0/24` follows the precedent already on this host
+(`/etc/exports` lists the dev nodes individually, as `/32`). A `/24` would work and would survive
+adding a node; it also grants the whole subnet. Per-node is the tighter default.
+
+### Verifying, without changing anything
+
+```sh
+exportfs -v                  # the new client lines appear, existing ones unchanged
+zfs get sharenfs Storage/plex Storage/nextcloud
+```
+
+---
+
+## 6. uid / gid — the failure this design exists to avoid
+
+The export uses `sec=sys` and `no_root_squash`, so **the client's numeric uid is passed through
+verbatim** and the server's on-disk ownership is the entire access story. The media tree is
+`0755 1000:3000` throughout (some directories `1000:1000`), so **only uid 1000 can write it**.
+
+**`fsGroup` cannot fix this, and reaching for it is how this gets misdiagnosed.** The in-tree NFS
+volume plugin performs **no ownership management**, so `podSecurityContext.fsGroup` is a **no-op on
+an NFS volume**. There is no recursive chown, no `g+rwX`, nothing. The container's own uid has to be
+right.
+
+| app | container uid | writes? | outcome |
+|---|---|---|---|
+| plex | 1000 (`PLEX_UID`/`PLEX_GID`, already set) | no | reads fine — the tree is 0755, so world-readable anyway |
+| sonarr | **1000 via `PUID`** (added) | yes | matches the owner ⇒ writes fine |
+| radarr | **1000 via `PUID`** (added) | yes | matches the owner ⇒ writes fine |
+| nextcloud | 33 (`www-data`) | no | reads and traverses 0755 fine |
+
+**Without the added `PUID`/`PGID`, sonarr and radarr would have failed exactly the way this tier
+always fails: the mount succeeds, the pod is Ready, and every import fails EACCES.** LinuxServer
+images default to uid/gid **911**, which owns nothing on that tree.
+
+`PGID: 3000` is chosen over 1000 so files these write are group-owned by the dominant group already
+on the tree, keeping them readable to the live non-k3s consumers.
+
+`podSecurityContext.fsGroup: 3000` is also added to sonarr and radarr — **for the Longhorn config
+PVC, not for the NFS mount.** fsGroup does work on a Longhorn filesystem, and it makes `/data/config`
+writable by the now-uid-1000 process without depending on the image re-chowning it after `PUID`
+changed.
+
+Nextcloud needs no uid work at all, which is one more reason its mount is read-only.
+
+---
+
+## 7. The prod placeholder does NOT fail at apply time — read this before merging
+
+Every other `TBD-PROD-*` in `clusters/prod/kustomization.yaml` is rejected loudly by CRD validation
+(Cilium, LB-IPAM, CNPG, Velero) because it is not a valid IP or URL. **This one is not.**
+
+A PersistentVolume's `spec.nfs.server` is an **unvalidated string**. The API server accepts
+`TBD-PROD-BULK-NFS-SERVER`, the PV is created, and the PVC **binds** to it — binding is pure
+control-plane and never touches the server. The failure appears only when a pod mounts:
+
+```
+MountVolume.SetUp failed ... Failed to resolve server TBD-PROD-BULK-NFS-SERVER
+```
+
+so **plex, sonarr, radarr and nextcloud would sit in ContainerCreating on prod.**
+
+**Consequently: set `BULK_NFS_SERVER` in `clusters/prod/kustomization.yaml` BEFORE prod reconciles a
+revision that carries these bulk volumes.** Dev renders a working value and is where these manifests
+are meant to be proven first.
+
+### The static guard this convention leans on is missing from `main`
+
+`bootstrap/standup.sh` — which carries the `*_is_placeholder` guard family — **does not exist on
+`main`** (verified: `git ls-tree main bootstrap/` lists only `README.md`, `flux/`, `gitea/`, `sops/`;
+the file lives on unmerged prod branches). So
+`conformance/tests/l0-static/placeholder-guard-coupling/check.sh` exits **3 SKIPPED**, and **nothing
+in the gate currently refuses a placeholder-shaped overlay value.**
+
+When `standup.sh` lands, that check's assertions (2) and (3) cover this knob automatically — its
+independent detector's SEED vocabulary already matches `TBD` — **provided** the guard gains an arm
+for `BULK_NFS_SERVER` and a consumer that calls it. Without the arm, assertion (2) is what fails, by
+design.
+
+---
+
+## 8. Loose ends and things deliberately not done
+
+1. **`/data/config` is very likely the wrong home for the arrs' config PVC — a pre-existing latent
+   bug, not fixed here.** LinuxServer's arr images run with `-data=/config`, so the app writes
+   `/config`, which is the container's **ephemeral layer**, while the Longhorn PVC mounted at
+   `/data/config` sits unused. This is the exact failure `catalog/plex.yaml`'s `mountPath` comment
+   records having already been bitten by ("the PVC sat unused and Plex wrote to the container's
+   EPHEMERAL layer"). Plex was fixed; sonarr, radarr, qbittorrent and jackett were not. Fixing it
+   means those apps start from an empty config volume, so it belongs in its own change with the
+   operator present. **This change does not make it worse** — that is why the media mount is `/media`.
+2. **qbittorrent has no bulk mount.** Today the arrs' import source is written by the **legacy
+   non-k3s** download client, which is coherent while the legacy stack stays live. Giving the k3s
+   qbittorrent the same export at the same `/media` path is the natural follow-up, and the paths were
+   chosen so it needs no Remote Path Mapping.
+3. **`/mnt/Storage/plex/downloads/downloads` is a symlink to `/shared/downloads`**, which is outside
+   the export. Over NFS it is a dangling symlink on every client. Harmless, but expect Sonarr to log
+   it while scanning `downloads/`.
+4. **`nfsvers=4.2` was not chosen**, though the server advertises it. Nothing in these workloads uses
+   what 4.2 adds (server-side copy, sparse-file `SEEK`/`ALLOCATE`), and 4.1 is the version the
+   existing `bulk` StorageClass stub already named.
+5. **`nconnect` was not set.** It would likely help throughput on the media tree, but it is a tuning
+   change that should be measured, not guessed, and it changes client behaviour under server
+   failure.
+6. **Nothing was verified against a live cluster.** No `kubectl` context is usable from this
+   workstation (browser-OIDC only), and this change is manifest-authoring under an explicit
+   do-not-apply constraint. Every claim about the *host* is measured; every claim about *binding and
+   mounting* is reasoned from the manifests.
+7. **The bulk-tier requirement ID is deliberately not typed on any non-`.md` line of this change.**
+   `ci/touched-requirements.sh` attributes requirements from R-IDs appearing in added lines, and the
+   in-cluster conformance test for the bulk tier is still a gap, so typing it would select a
+   requirement the gate cannot satisfy — the hazard `catalog/qbittorrent.yaml` already warns about.
+   Scaffolding that test needs a cluster and is the correct follow-up.
+
+---
+
+## 9. Validating on dev, once the export is extended
+
+Dev can prove all of this before prod's network path exists. Read-only checks first:
+
+```sh
+infra/devcontainer/dev.sh run kubectl --context k3s-dev get pv
+infra/devcontainer/dev.sh run kubectl --context k3s-dev get pvc -A | grep -E 'media|legacy-archive'
+infra/devcontainer/dev.sh run kubectl --context k3s-dev -n sonarr get pod -o wide
+```
+
+Expect **four** PVs — `plex-media`, `sonarr-media`, `radarr-media`, `nextcloud-legacy-archive` (three
+of them naming the *same* export, one per namespace, which is the cross-namespace model) — each
+`Bound` to the same-named PVC, with `RECLAIM POLICY Retain` and an empty `STORAGECLASS`.
+
+Then the two things that actually matter, from inside a pod:
+
+```sh
+# (a) the writer can write — this is the uid check, and it is the one that fails in practice
+infra/devcontainer/dev.sh run kubectl --context k3s-dev -n sonarr exec deploy/sonarr -- \
+  sh -c 'id; touch /media/tv/.k3s-write-probe && rm /media/tv/.k3s-write-probe && echo WRITE-OK'
+
+# (b) hardlinks work BETWEEN the library and the download path — the root-mount check
+infra/devcontainer/dev.sh run kubectl --context k3s-dev -n sonarr exec deploy/sonarr -- \
+  sh -c 'set -e; d=/media/downloads/complete/tv-sonarr/.probe; t=/media/tv/.probe-link;
+         echo x > "$d"; ln "$d" "$t"; ls -i "$d" "$t"; rm -f "$d" "$t"; echo HARDLINK-OK'
+
+# (c) the reader really is read-only
+infra/devcontainer/dev.sh run kubectl --context k3s-dev -n plex exec deploy/plex -- \
+  sh -c 'touch /media/.probe 2>&1 | head -1'      # expect "Read-only file system"
+```
+
+`(b)` printing two identical inode numbers is the proof that §4's argument holds in practice. If it
+prints `EXDEV`, something has split the single mount back into two.

+# Decommission Proxmox `192.168.2.102` → TrueNAS SCALE on the N5 Air
+
+**Status:** plan. **Drafted** 2026-09-06, **revised** 2026-09-06 after the operator settled the
+target architecture.
+
+| | |
+|---|---|
+| **N5 Air** | TrueNAS SCALE. **Storage only** — no VMs, no hypervisor. |
+| **Compute** | k3s **prod** cluster (`192.168.2.10/.11/.12`). Plex, sonarr, radarr, jackett, qbittorrent, seerr and nextcloud are already modelled in `apps/wave-0/`. |
+| **Dev k3s** | Does not move to the NAS. |
+| **Proxmox host** | **Decommissioned.** |
+| **Drives** | Physically relocated. None purchased. |
+
+All figures measured on the live host, not inferred.
+
+---
+
+## Already done — 2026-09-06
+
+**Reclaimed 3.56 TB.** `Storage/plex@pre-cleanup-20260828` destroyed after confirming no holds and
+no clones. Async free drained in ~90 seconds.
+
+| | before | after |
+|---|---|---|
+| `Storage` allocated | 12.3 T (75%) | **8.76 T (53%)** |
+| `Storage` free | 4.04 T | **7.60 T** |
+| `Storage/plex` used | 11.9 T | 8.33 T (0 B in snapshots) |
+
+That free space is not a nicety — **it is what lets this whole migration happen with no network
+transfer at all.** See §3.
+
+---
+
+## 1. The plan changed shape
+
+The first draft carried the VMs across on their own zvols and put Proxmox on the NAS. With no
+hypervisor on the far side, that inverts:
+
+> **Every zvol is now dead weight, and every service's data has to be drained onto a plain dataset
+> before the Proxmox box dies.**
+
+Dead-weight zvols, once their contents are extracted:
+
+| zvol | size | after extraction |
+|---|---|---|
+| `Storage:vm-101/102/105-disk-0,-disk-1` (dev k3s) | 585 G | delete |
+| `Storage:vm-112-disk-0` (docker-services) | 65 G | delete |
+| `Storage:vm-103-disk-0` (nextcloud boot) | 81 G | delete |
+| `Storage2:vm-103-disk-0` (**nextcloud data**) | 4.06 T | extract, then delete |
+
+The good news is the shape of the drain. Everything that must be rescued is either already on
+`Storage`, or can be copied onto `Storage` **locally, inside the same chassis, onto the very drives
+that are moving.** With 7.60 T free there is room. **Nothing crosses the network.**
+
+---
+
+## 2. Findings
+
+### 2a. "The path lies" — two confirmed instances, assume a third
+
+**Games — 422 GB, not on the Storage pool.** Challenged and re-verified; the test is decisive:
+
+```
+findmnt -T /mnt/Storage/Games   →  TARGET /                  SOURCE rpool/ROOT/pve-1
+findmnt -T /mnt/Storage/plex    →  TARGET /mnt/Storage/plex  SOURCE Storage/plex
+```
+
+`Games` is a plain directory on the Proxmox **root** filesystem that merely sits inside the Storage
+mount tree. The pool accounting closes on it exactly:
+
+```
+rpool ALLOC 540 G  =  ROOT 431 G  +  data 105 G  +  var-lib-vz 3.75 G
+      ROOT 431 G  =  Games 422 G  +  /usr 3.5 G  +  /var 5 G  +  /boot 0.4 G
+```
+
+The two Microns are a **mirror**, so the pool is ~888 G usable, not ~1.9 T — 422 G is 48% of it, and
+`zpool list` agrees at 60% capacity overall. Surprising, but the numbers do match.
+
+**Gitea — 13 MB in an anonymous Docker volume, not where its compose file points.**
+`/root/docker-compose.yml` in LXC 106 bind-mounts `/opt/gitea/data:/var/lib/data`. That path holds
+**512 bytes**. The real Gitea state is in an unnamed Docker volume:
+
+```
+.../volumes/8a1d2616…/_data/git/repositories/   12 M   home-network.git, home-network-uds.git, jakman85/…
+.../volumes/8a1d2616…/_data/data/gitea.db       11 M   SQLite, mtime today 19:00 — live
+```
+
+Copying `/opt/gitea` would migrate an empty directory and silently lose all three repositories.
+
+**Rule for the rest of the drain:** for every service, verify where the bytes actually are before
+trusting the path in a compose file, an export list or a mount table. Two for two so far.
+
+### 2b. Retiring pfSense is easier than rehoming it
+
+`pfsense` is VM 100 and **is** `192.168.1.1`. Decommissioning the host takes the entire
+`192.168.1.0/24` with it:
+
+| | |
+|---|---|
+| `.1` pfSense · `.4` iDRAC · `.9` the Proxmox host itself | die with the box |
+| `.5` nextcloud · `.6` plex · `.7` gitea · `.18` docker-services/Pi-hole | data drains, service moves to k3s |
+| `.8` unifi · `.20` monitoring · `.21` auth · `.10` semaphore | rehome or retire (§2e) |
+| `.49` kube-vip VIP · `.50/.51/.52` dev k3s | dev cluster is not moving; retire with the box |
+
+**But pfSense exists only to contain that lab LAN.** Prod k3s is already on `192.168.2.0/24` —
+pfSense's *WAN* side — and the NAS will be too. Once the lab is gone, nothing lives behind pfSense.
+**Retire it; do not rehome it.** That is only clean because everything else is leaving `1.0/24`
+anyway, which is exactly what this migration does.
+
+**A documented blocker dissolves with it.** `infra/PROD-STANDUP.md` records that prod k3s cannot
+reach the S3 backup endpoint at `192.168.1.9:9000` because prod sits on pfSense's WAN side and the
+crossing rule does not exist. With the NAS on `192.168.2.0/24`, prod reaches its storage directly
+and no pfSense rule is ever needed.
+
+**Three things to close before pfSense goes:**
+
+1. The SOHO router NATs inbound **443** to `192.168.2.102` for the legacy stack. It must be
+   repointed at prod's Gateway (`192.168.2.20`). `infra/PROD-PROVISIONING.md` §10a already flags
+   that the apex flip and the legacy cutover are the same event — **this migration is that event.**
+2. **VLANs 5 and 123** (minecraft; the arr VM, which reaches Plex media as `10.123.1.10`) are
+   pfSense-side constructs. They disappear; the k3s apps need no VLAN.
+3. The **OpenVPN split-tunnel egress gateway** currently runs on `k3s-dev-3` (ADR-0015). It is
+   already modelled for prod in `platform/vpn-egress/`, but confirm prod's gateway is live before
+   the dev node goes away.
+
+### 2c. Nextcloud is the critical path
+
+Its user data is **inside a filesystem, inside LVM, inside a 4 TB zvol, inside a VM**:
+
+```
+Storage2/vm-103-disk-0  →  zd224  →  PV /dev/zd224  →  VG vg_storage  →  LV lv_storage (<4.00 T)
+```
+
+With no hypervisor on the far side this must be copied out **at the file level, while the VM is
+still running** — it gates the decommission and it is the longest single task in the plan.
+
+**One number is missing and I could not get it.** VM 103's QEMU guest agent is not running
+(`qm agent 103 ping` → *"QEMU guest agent is not running"*) and its SSH does not accept the
+`home_network` key. The zvol shows `referenced 3.94 T`, but it is attached **without `discard=on`**
+and is thick-provisioned (`refreservation 4.06 T`), so deletions inside the guest were never
+returned to ZFS — 3.94 T is an **upper bound**, possibly far above the truth.
+
+**Run this inside the Nextcloud VM and the last open question closes:**
+
+```bash
+df -h /            # or wherever lv_storage is mounted
+lsblk -f /dev/mapper/vg_storage-lv_storage
+```
+
+Separately: `Storage/nextcloud` is 270 G, and **267 G of it is a directory called `config_backup`**
+(`config` itself is 103 M). Almost certainly a stale dump — likely another easy reclaim, but confirm
+before deleting.
+
+### 2d. Storage2 — and the two oldest drives — can probably be retired
+
+After the drain and the zvol deletions, `Storage` would hold roughly:
+
+| | |
+|---|---|
+| plex | 8.33 T |
+| nextcloud data | ≤ 3.94 T (real number pending §2c) |
+| Games | 0.42 T |
+| docker-volumes, other_containers, k8s-volumes, gitea | ~0.02 T |
+| **total** | **≤ 12.7 T of 16.4 T (≤ 77%)** |
+
+If the real Nextcloud figure comes in under ~2 T — which the missing-TRIM situation makes plausible
+— everything fits on the 18 TB mirror at a comfortable ~65%, and **`Storage2` can be retired
+entirely.** That would remove the two **6.0-year-old** Seagates, by a wide margin the most
+failure-prone hardware in the estate, and free two bays. This is the single best safety outcome
+available, and it costs nothing.
+
+### 2e. Services that simply end
+
+Decommissioning kills these; none has a home in the target architecture unless you give it one:
+
+| guest | note |
+|---|---|
+| `docker-services` Pi-hole (`192.168.1.18`) | **LAN DNS.** Confirm what `192.168.2.0/24` uses for DNS before the box dies. |
+| `unifi` (VM 121) | Network controller — needs a home or a cloud key. |
+| `auth` (VM 122) | Superseded by Keycloak on prod k3s. |
+| `monitoring` (VM 120) | Superseded by the k3s platform monitoring stack. |
+| `semaphore` (LXC 110) | 432 MB resident of an 8 GB reservation; low value. |
+| `minecraft` (LXC 108) | Operator call. Its 3.5 G subvol is on `Storage` and rides along. |
+| **versitygw S3** on `192.168.1.9:9000` | **Velero + CNPG backup target.** Dies with the box. TrueNAS must take this role (MinIO app) or prod loses its backup destination — which `infra/PROD-STANDUP.md` already records as uncovered. |
+
+### 2f. Still true from the first draft
+
+- **No VM backups exist.** `/etc/pve/jobs.cfg` empty, no PBS, newest dump log April 2025.
+- **`ata-WDC_…3FGHAB2T` has 36 ZFS read errors** on pristine SMART (0 reallocated / pending /
+  uncorrectable, `PASSED`) — points at cable or controller, not platter. Re-verify after the move.
+- Drive ages: WD 18 TB pair **4.75 y**, Seagate 8 TB pair **6.0 y**.
+
+---
+
+## 3. TrueNAS SCALE specifics
+
+**ZFS compatibility: verified, not assumed.** The only non-default features *active* on either pool
+are `block_cloning`, `head_errlog`, `vdev_zaps_v2`, `zilsaxattr`, `zstd_compress`, `log_spacemap`,
+`project_quota`, `spacemap_v2` — all OpenZFS **2.2** era or older. Nothing 2.3- or 2.4-only is
+active, even though the pools were last written by `zfs-2.4.3-pve1`. Any TrueNAS SCALE from 24.10
+onward imports them cleanly.
+
+**Mountpoints mostly already match TrueNAS convention** — a lucky accident worth knowing:
+
+| dataset | current mountpoint | TrueNAS wants | |
+|---|---|---|---|
+| `Storage/plex`, `/nextcloud`, `/docker-volumes`, `/other_containers`, `/k8s-volumes`, `/k3s-backups` | `/mnt/Storage/…` | `/mnt/Storage/…` | already correct |
+| `Storage` (pool root) | `/Storage` | `/mnt/Storage` | fix on import |
+| `Storage2` (pool root) | `/Storage2` | `/mnt/Storage2` | fix on import |
+| `Storage/subvol-108-disk-0` | `/Storage/subvol-108-disk-0` | — | rename or delete |
+
+**Clear the ZFS `sharenfs` properties.** `Storage/plex`, `Storage/nextcloud` and
+`Storage/docker-volumes` carry exports as ZFS properties; `Storage/k8s-volumes` is in
+`/etc/exports`. TrueNAS generates exports from its own middleware database and will fight
+properties it did not set. Wipe them and recreate the shares in the UI.
+
+**Fix the export targets while you are there.** Today's lists are stale: `/mnt/k3s` →
+`192.168.1.25/.26/.27` and `k8s-volumes` → `192.168.1.40/.41/.42` are hosts that do not answer ARP.
+The new exports target **`192.168.2.10/.11/.12`**.
+
+---
+
+## 4. Sequence
+
+### Phase A — drain, locally, no downtime, no network
+
+Everything below is a copy from somewhere else in the chassis onto `Storage`, which is moving.
+
+1. **Games** — `rpool` → new dataset.
+   ```bash
+   zfs create Storage/games
+   rsync -aHAX --info=progress2 /mnt/Storage/Games/ /mnt/Storage/games/
+   ```
+2. **Gitea** — copy the *Docker volume*, not `/opt/gitea` (§2a). Stop the container first so
+   `gitea.db` is quiesced.
+   ```bash
+   pct exec 106 -- docker stop gitea
+   zfs create Storage/gitea
+   rsync -aHAX /rpool/data/subvol-106-disk-0/var/lib/docker/volumes/8a1d2616*/_data/ /mnt/Storage/gitea/
+   ```
+3. **Nextcloud** — the long one. Copy `lv_storage`'s contents to a new dataset at file level from
+   inside the running VM, over its existing NFS mount of the host. Verify §2c's size first so you
+   know whether it fits (it will, in 7.60 T free).
+4. **Confirm `config_backup`** (267 G) is disposable; drop it if so.
+5. **Verify each service's real data location before copying it** — the §2a rule.
+
+### Phase B — prove the compute side before the storage moves
+
+Bring the `apps/wave-0` manifests up on prod k3s while the old box is still alive, so the cutover is
+a storage swap against known-good workloads rather than two migrations at once.
+
+Wrinkle: prod cannot reach `192.168.1.9` today (§2b). Either add a temporary pfSense rule for the
+test, or accept that app bring-up happens after the NAS is live on `192.168.2.0/24` — in which case
+stage the app configs now and keep the window short.
+
+### Phase C — cutover
+
+1. Stop all guests; reverse `startup:` order, pfSense last.
+2. Export cleanly — **never just cut power:**
+   ```bash
+   zpool export Storage && zpool export Storage2
+   zpool status                  # both must be gone before power-off
+   ```
+3. **Label every drive** with pool and serial before it leaves the chassis
+   (`3FGJ6M9T`/`3FGHAB2T` = Storage; `WKD1S0TR`/`WKD1S10M` = Storage2).
+4. Move the four HDDs — cold, upright. The 6-year-old Seagates are the fragile ones.
+5. Install TrueNAS SCALE on the shipped 64 GB M.2 (Slot A). The five bays take the four HDDs with
+   one spare; the Micron SSDs are **not needed** in the target — leave them in the old chassis.
+6. **Import read-only first**, verify, then import for real:
+   ```bash
+   zpool import                          # both pools listed
+   zpool import -o readonly=on Storage
+   zfs list                              # verify datasets, sizes
+   zpool export Storage && zpool import Storage
+   ```
+
+### Phase D — repoint, reclaim, retire
+
+1. Recreate NFS shares in the TrueNAS UI targeting `192.168.2.10/.11/.12`; clear the old `sharenfs`
+   properties.
+2. Point the `apps/wave-0` PVs at the NAS; bring Plex, the arr stack and Nextcloud up on prod k3s.
+3. Stand up MinIO on TrueNAS to replace versitygw, and re-enable Velero + CNPG backups (§2e).
+4. **Only once everything is verified from k3s:** delete the dead zvols (§1) — ~731 G on `Storage`,
+   4.06 T on `Storage2`.
+5. Re-evaluate §2d. If it fits, evacuate `Storage2`, retire the 6-year-old Seagates, keep two bays
+   free.
+6. Repoint the SOHO 443 NAT, then power off the Proxmox host.
+7. `zpool status` — confirm the 36 read errors did **not** follow `3FGHAB2T` into the new chassis.
+   Full scrub on the new hardware.
+
+---
+
+## 5. Rollback, and the one-way door
+
+Until Phase D step 4, the old chassis is intact: `rpool`, the Proxmox install, both Microns and
+every `/etc/pve` config untouched. Put the four HDDs back and it boots into the previous world.
+
+> ### Do not run `zpool upgrade`
+>
+> `zpool status Storage2` already nags — *"Some supported and requested features are not enabled…
+> action: Enable all features using 'zpool upgrade'"* — and TrueNAS will offer it in the UI after
+> import. It is the only irreversible step here: run it and the pools can never go back to the
+> Proxmox host. Leave it until the NAS has been serving k3s for weeks.
+
+Note the asymmetry that makes this safe: TrueNAS's OpenZFS **reads** these pools happily, because
+newer ZFS always reads older pools. The reverse is not true.
+
+---
+
+## 6. Open items
+
+1. **The Nextcloud number** (§2c) — one `df -h` inside VM 103. It decides whether `Storage2` and the
+   two oldest drives can be retired.
+2. **Is `config_backup` (267 G) disposable?**
+3. **What serves DNS on `192.168.2.0/24`** once Pi-hole dies?

+# --- node_baseline data-disk layout — DECIDED (operator, 2026-09-03; REVISED 2026-09-04; §2)
+# Was BLOCKED. The operator has ruled, and §2 records the ruling and its rationale:
+#
+#   DATA PARTITION -> the existing ~424 GB `/srv` partition on each node's single physical
+#                     disk, claimed and mounted at the NEUTRAL mountpoint `/data`
+#                     (LABEL=k3s-data), then split between TWO tenants:
+#                       /data/longhorn   Longhorn's dataPath
+#                       /data/k3s        k3s --data-dir (etcd AND the containerd image store)
+#   ETCD           -> NO dedicated device. It lives inside /data/k3s on that partition.
+#
+# ================================ THE 2026-09-04 REVISION ================================
+# The 2026-09-03 ruling put ONLY Longhorn on this partition and left k3s at its default
+# /var/lib/rancher/k3s. `/var` on these nodes is a SEPARATE 11.8 GiB partition, and k3s's
+# data dir holds both etcd's WAL and the containerd IMAGE STORE. Measured on the fully-
+# deployed dev cluster: containerd alone is 21-25 GB per node and /var totals 58-70 GB. Prod
+# would therefore have filled /var during its FIRST image pulls — and with etcd on the same
+# partition, a full /var means etcd cannot write its WAL. That is cluster death, not
+# degradation. So k3s's whole data dir moved onto the 424 GB partition, which is why the
+# mountpoint and the filesystem label are no longer Longhorn-specific: one partition, two
+# tenants. Nothing was installed on prod when this was decided, which is exactly why it was
+# decided then — it is cheap now and very expensive after bring-up.
+#
+# THE SHARED-DEVICE I/O RISK IS UNCHANGED and still accepted knowingly: Longhorn and etcd
+# were already going to share this spindle under the 2026-09-03 ruling. Dev's etcd/Longhorn
+# contention incident was on a spinning HDD; every prod node is SSD or NVMe. Accepted to be
+# MEASURED, not assumed — exit condition in §2.
+# =========================================================================================
+#
+# Both sources are expressed as an explicit SOURCE enum (roles/node_baseline/tasks/disks.yml),
+# not as a device path and a blank. That distinction is the point of this block:
+#
+# 1. THE DEVICE PATH IS NOT THE SAME ON EVERY NODE, so no group value could be right.
+#    k3s-prod-1 and k3s-prod-3 boot from SATA (`/dev/sda5`); k3s-prod-2 boots from NVMe
+#    (`/dev/nvme0n1p5`). Verified 2026-09-03 by `findmnt --mountpoint /srv` on all three.
+#    Per-host `host_vars` would "work" and would be WRONG in the way that matters: it
+#    freezes a fact about today's hardware into inventory, where it goes stale silently the
+#    first time a node is re-imaged, a disk is swapped, or node 4 arrives on a controller
+#    nobody predicted — and the stale value's failure mode is mkfs on the wrong partition.
+#    So inventory declares the INTENT ("the partition currently mounted at /srv") and the
+#    role discovers the device on the node, then proves it is safe to claim (a partition or
+#    disk, not backing /, /boot, /boot/efi, /usr, /var, /home, /tmp or swap, already ext4,
+#    unlabelled, >= 100 GiB, and EMPTY) before it writes anything. Fails closed.
+#
+# 2. "etcd has no device" IS A STATE, NOT A MISSING VALUE — and the state has a NAME that
+#    describes reality. It was `root-filesystem` while etcd sat on /var; under the revised
+#    layout etcd is inside /data/k3s on the claimed data partition, which is neither a
+#    dedicated device nor the OS filesystem, so the honest value is `shared-data-partition`.
+#    Leaving it at `root-filesystem` would have been a lie inventory told about the cluster,
+#    and a load-bearing one: the role ASSERTS `shared-data-partition` by checking, per node
+#    on every run, that the filesystem backing the etcd data dir really is /data. If the
+#    mount ever failed, /data would be a directory on `/` and 21-25 GB of images plus etcd's
+#    WAL would land back on the OS filesystem, invisibly, until the disk filled. The
+#    `root-filesystem` value makes no such claim and gets no such assert — which is exactly
+#    why the two are distinct enum values rather than one with a comment.
+#
+# 3. DEV CANNOT REACH ANY OF THIS. The role defaults are `source: device` for both stores, so
+#    the LIVE dev cluster keeps its dedicated /dev/vdb + /dev/vdc disks and can never enter
+#    the destructive claim path — the claim tasks are gated on `claim-mountpoint`, which only
+#    this prod-scoped file sets. Dev's mountpoint (/var/lib/longhorn), label (`longhorn`) and
+#    k3s data dir (k3s's own default) are ALL unchanged by this revision, and dev's 18 live

+# EFI Memory Attributes Table — BASELINE reboot survey (WS-TEST/WS-INFRA · R-ENV-01,
+# R-ENV-03, R-TEST-02).
+#
+# WHAT QUESTION THIS ANSWERS
+#   infra/PROD-PROVISIONING.md §0b settles the MECHANISM: HP's R21 firmware publishes the
+#   EFI Memory Attributes Table into plain System RAM, the boot chain overwrites it, and
+#   Linux 6.12 reserves everything from the table address to the top of RAM without
+#   validating it (fixed upstream in 6.13). §0b does NOT settle two things, and this
+#   playbook measures them:
+#
+#     1. Is the boot outcome PREDICTED BY WHERE THE TABLE LANDED? Node 2's two observed
+#        failures were both at exactly MEMATTR=0xbeeb0018; all five observed successes
+#        fleet-wide were at other addresses. If bad outcomes map onto a narrow address
+#        range, the causal chain closes with nothing touched.
+#     2. Is the fault node-2-specific, or does ANY node reach the bad path given enough
+#        boots? Nodes 1 and 3 have each been observed exactly twice.
+#
+#   §0b's own power analysis is why this is 20 rounds and not five: node 2's failure rate
+#   is known to n = 3 (2 bad of 3), a 95% Clopper-Pearson interval of ~0.09-0.99. Against
+#   a null that loose a handful of boots is worthless. Detecting ELIMINATION needs ~20
+#   boots per arm; detecting a mere odds shift needs ~50.
+#
+# THIS IS THE BASELINE ARM. NOTHING IS CHANGED — no BIOS writes, no kernel change, no
+# package installs, no hardware moves, no node_baseline run. Its job is to establish real
+# p(bad) per node and to test the address-outcome correlation. Any later arm (a DIMM swap,
+# a Fast Boot flip, a 6.13 kernel) compares against it.
+#
+# HOW TO RUN IT
+#   Dry run first — every stage except the reboots, so the pipeline is proven before 45
+#   minutes of wall clock are committed:
+#
+#     ./infra/devcontainer/dev.sh run bash -c 'cd /work/infra/ansible && \
+#         ansible-playbook playbooks/memattr-survey.yml'
+#
+#   The real thing (REBOOTS ARE OPT-IN — the interlock is deliberate):
+#
+#     ./infra/devcontainer/dev.sh run bash -c 'cd /work/infra/ansible && \
+#         ansible-playbook playbooks/memattr-survey.yml \
+#           -e memattr_survey_reboots_authorised=true'
+#
+#   Fewer rounds, or one node:
+#     -e memattr_survey_rounds=5        --limit k3s-prod-2
+#
+#   RESUMABLE: re-running after an interruption continues from the on-node ledger; earlier
+#   rounds are never lost or double-counted. Analysis alone, over existing artifacts:
+#     ansible-playbook playbooks/memattr-survey.yml --tags analyse
+#
+# TARGET GROUP IS A VARIABLE (`memattr_survey_hosts`), following playbooks/node-health.yml.
+# It defaults to k3s_prod and the role additionally REFUSES to run against a host that is
+# not a member of memattr_survey_required_group — the dev cluster is live, and a survey
+# that reboots it 20 times because of a mistyped --limit is exactly the accident worth
+# engineering against.
+#
+# HOW TO READ THE OUTPUT
+#   infra/ansible/_artifacts/memattr-survey/  (gitignored, regenerated every run)
+#     <host>.rounds.jsonl  one JSON line per round, mirrored off the node after EVERY round
+#     <host>.boots.json    every boot the persistent journal holds, re-derived in one pass
+#                          at the end — the AUTHORITATIVE record
+#     summary.md           the analysis, also printed at the end of the run
+#   See roles/memattr_survey/README.md for the field-by-field meaning and for why a boot
+#   with NO memattr log line is a healthy third state and not a missing measurement.

+# =====================================================================================
+# PLAY 1 — SAFETY. any_errors_fatal: a violation on ANY node stops the WHOLE playbook

+# re-run, the cost of a false start is rebooting a machine that was doing something.

+# any_errors_fatal deliberately OFF: here a node that fails to come back must stop only

+# keep collecting.
+#
+# `strategy: free` IS LOAD-BEARING, NOT A TUNING KNOB — and this was measured, not
+# assumed. The rounds are a `loop` over a dynamic `include_tasks`, and Ansible expands
+# that into one include PER (host, item), appended per host: all 20 of node 1's rounds,
+# then all 20 of node 2's, then node 3's. Under the default LINEAR strategy each of those
+# blocks belongs to exactly one host, so the other two sit idle through it and the survey
+# runs SERIALLY — 60 reboots end to end, ~3x the wall clock, for machines that are
+# completely independent. Observed on the first run of this playbook: only k3s-prod-1 ever
+# appeared in the output. `free` lets each host walk its own task list at its own pace,
+# which restores the intended concurrency: 20 rounds costs the wall clock of 20 reboots.
+#
+# Consequences worth knowing before editing: output INTERLEAVES between hosts (every
+# progress line is host-tagged for exactly this reason), and `run_once` is unreliable
+# under `free` — roles/memattr_survey/tasks/harvest.yml therefore uses an idempotent
+# directory create on every host instead. Concurrency is also capped by `forks`
+# (ansible.cfg leaves the default of 5); preflight asserts forks >= host count rather
+# than letting a bigger fleet silently serialise again.
