fix(bulk-nfs): repoint at the TrueNAS (192.168.2.30); the PVs must be recreated, not reconciled

Both ZFS pools moved off the Proxmox host onto a standalone TrueNAS on 192.168.2.30 -- prod's OWN /24, so the pfSense crossing that made this knob load-bearing is gone, along with the DNAT at 192.168.2.102 it mounted through. Measured 2026-10-07: 192.168.2.102:2049 no longer answers; .30:2049 and :111 do. BULK_NFS_SERVER -> 192.168.2.30 in prod, base and dev. The dev value is marked inert (dev is decommissioned); it carries the real address only so nothing in the tree renders a host that no longer exists. THE OPERATIONAL POINT, and why this is not just a value change: a bound PersistentVolume's NFS source is immutable. Server dry-run, 2026-10-07: spec.persistentvolumesource: Forbidden: spec.persistentvolumesource is immutable after creation so Flux's apply FAILS rather than updating, and the pods keep their old, dead mount. The five PVs must be deleted and recreated -- safe, because Retain never touches data and render.py emits a pre-set claimRef so each PV rebinds its own PVC. The sequence is docs/BULK-NFS-STORAGE.md section 10 and is an OPERATOR action; this commit does not perform it. Pairs with the hazard already on the page: spec.nfs.server is unvalidated at create (any string binds) and immutable at update. A wrong value is accepted silently and then cannot be corrected in place. docs/BULK-NFS-STORAGE.md: sections 1 and 5 rewritten for TrueNAS -- the measured exports, the service settings that decide whether uid 1000 survives the wire, the three stale ZFS sharenfs properties that had to be cleared, and the ACL hazard (acltype=nfsv4 + aclinherit=passthrough means one click in the ACL editor propagates to the whole future library). Section 7 rewritten now that the placeholder is gone, section 9 retargeted from dev to prod, section 10 new. Sections 2/3/4/6 are unchanged by the move.

+branch: docs/pm-agent-registry-pull-prereq
+title: pm-agent reconciled exactly as designed — and is the first workload ever to pull from the in-cluster registry, which does not work yet
+---
+
+## What changed
+
+Documentation only. No manifest, no policy, no code.
+
+PR #57 merged and `pm-agent` reconciled. I measured what landed, and the measurement turned
+up **two prerequisites for the next operator step that nothing in this repository
+declares** — and that the handoff entry for #57 could not have known, because it listed the
+image pull as unverified and that is exactly where it bit.
+
+So this entry records the post-merge measurement, and
+`platform/pm-agent/README.md`, `docs/plans/pm-agent-issue-to-pr.md` and
+`runbooks/pm-agent.md` now name both prerequisites where they say "build, push, pin the
+digest". Before this, that step read as one action; it is three, and the two new ones are
+not an agent's to perform.
+
+**The finding is not specific to pm-agent.** `conformance-runner` has the identical
+registry path (`gitea.home.keithjackson.dev/home-network/...`), the identical "operator
+pushes, a digest goes in a PR" model, and has never been pulled either — so the same two
+blockers sit in front of the L2/L3 conformance wiring. Measured: **no pod anywhere in the
+cluster references that registry** except the pm-agent dispatcher, which is therefore the
+first workload ever to try it.
+
+## What I verified
+
+Read-only, through the pinned toolbox, against the live prod cluster.
+
+**The merge reconciled, completely and exactly as designed.**
+
+- `GitRepository/flux-system` artifact revision: `main@sha1:95597bd6883637…` — the merge
+  commit. `platform-config`, `pm-agent` and `apps-wave-0` all report that same
+  `lastAppliedRevision` with `Ready=True`. Compared field to field, per CLAUDE.md §2b,
+  rather than assumed from the merge.
+- **The security boundary is live.** `ClusterPolicy/pm-agent-job-shape`:
+  `validationFailureAction=Enforce`, `failurePolicy=Fail`, `Ready=True`, and all six rules
+  present (`worker-must-be-the-committed-shape`,
+  `worker-must-be-one-container-with-no-args`,
+  `worker-volumes-must-be-workspace-or-tmp-emptydirs`,
+  `worker-may-not-declare-init-or-ephemeral-containers`,
+  `worker-env-names-must-be-the-committed-set`, `worker-may-not-use-envfrom`). This is the
+  check that mattered most: a ClusterPolicy added to the wrong kustomization list ships
+  green and never reaches the cluster, which is what happened to the conformance boundary
+  on 2026-09-29.
+- Namespace contents: both ServiceAccounts, `pm-agent-config` (17 keys), the
+  `pm-agent-credentials` Secret, the `default-deny` NetworkPolicy, and both
+  CiliumNetworkPolicies with `VALID=True`.
+- **SOPS decryption works through the new overlay patch.** Checked by KEY NAMES and VALUE
+  LENGTHS only, never values (CLAUDE.md §6): keys `gitea-token`, `claude-code-oauth-token`,
+  lengths 76 and 52 bytes — which are the base64 lengths of the committed placeholder
+  strings, so the Secret holds the decrypted placeholders and not ciphertext. A
+  ciphertext apply succeeds silently and would have left `ENC[AES256_GCM,…]` values an
+  order of magnitude longer.
+- **`pm-agent-worker` really is bound to nothing.** The namespace has exactly one
+  RoleBinding (`pm-agent` → Role `pm-agent`, subject `ServiceAccount/pm-agent`), and no
+  ClusterRoleBinding anywhere names either pm-agent ServiceAccount.
+- `gitea-allow-pm-agent-ingress` is applied in the `gitea` namespace, matching
+  `io.kubernetes.pod.namespace: pm-agent`.
+- The dispatcher is `ImagePullBackOff` on the all-zero placeholder digest — the designed,
+  visible failure.
+
+**The two prerequisites, measured.**
+
+1. **The nodes cannot verify the registry's TLS certificate.** containerd's error on the
+   pull is not about the digest:
+
+       failed to resolve reference "gitea.home.keithjackson.dev/home-network/agent-runner@sha256:000…":
+       tls: failed to verify certificate: x509: certificate is not valid for any names,
+       but wanted to match gitea.home.keithjackson.dev
+
+   "not valid for **any** names" means the certificate presented to the node carries no
+   matching SAN at all. From the operator's workstation the same name is healthy: it
+   resolves to `192.168.2.20` and serves a Let's Encrypt certificate
+   `CN=*.home.keithjackson.dev` with SANs `*.home.keithjackson.dev, home.keithjackson.dev`
+   — and `Certificate gateway/wildcard-home` is `Ready=True` for exactly those names. So
+   the certificate that *should* be served is fine, and what the NODE reaches is not what
+   the workstation reaches. **Correcting the digest will not clear this.**
+2. **Anonymous pulls from this registry are refused.** Not inferred from a bare 401 — that
+   would have been wrong, because this Gitea answers 401 for *everything* anonymously:
+   `/v2/home-network/agent-runner/manifests/latest`, `/v2/home-network/conformance-runner/…`,
+   a randomly-named nonexistent repository, and `nosuchowner/nosuchimage` all return 401,
+   and `/api/v1/packages/Home-Network` returns `{"message":"token is required"}`. The
+   registry *does* issue a token to an anonymous client, but its `access` claim is `null` —
+   no pull scope. So the conclusion that holds is the simple one: **an unauthenticated
+   client gets nothing from this registry**, so a pull with no credential cannot succeed.
+   And `grep` over the tree finds **no `imagePullSecrets` anywhere** — not in
+   `platform/pm-agent/deployment.yaml`, not in `infra/agent/worker-job-template.yaml`, not
+   in `conformance/incluster/`.
+
+## What I did NOT verify
+
+- **Why the node sees a nameless certificate.** I measured that it does, and that the LAN
+  does not. I did not diagnose it: I did not read the nodes' resolver or
+  `/etc/rancher/k3s/registries.yaml` (node files, not reachable read-only through the API),
+  and I did not check whether the node resolves the name to the same `192.168.2.20` the
+  workstation does or to something else.
+
+  **A correction to a remark I first wrote here:** I cited
+  `cluster-vars`'s `GATEWAY_VIP: 192.168.1.53` as suspicious next to the nodes'
+  `192.168.2.x`. That was noise — the operator confirms those base `cluster-vars` values are
+  **dev-era leftovers for a cluster that is decommissioned**, so the 192.168.1.x addresses in
+  that file say nothing about prod and should not be read as evidence about anything. The
+  measured facts stand on their own and none of them depended on that knob.
+- **Whether the package would be pullable once authenticated.** Nothing has ever been
+  pushed to that path, so "a credential is sufficient" is untested. The only thing
+  established is that no credential is insufficient.
+- **Which fix the operator wants.** Two routes, and they are not equivalent:
+  (a) an `imagePullSecret` — a `dockerconfigjson` holding a Gitea token, SOPS-encrypted
+  like `pm-agent-credentials`, referenced from the Deployment *and* from the committed
+  worker Job template; note the Job template's shape is pinned by admission, and
+  `imagePullSecrets` is a field that policy does not currently constrain, so adding one is
+  a template change that needs a deliberate look at whether the policy should pin it too.
+  (b) allowing anonymous reads of that package in Gitea — no manifest change at all, but it
+  makes the image world-readable to anything that can reach the host.
+  I have implemented neither: both need an operator action I must not take, and (b) is a
+  posture decision. The docs now present both.
+- **Everything the #57 entry listed as unverified about RUNTIME remains unverified.** The
+  image has still never been built or pushed. No dispatcher has authenticated to Gitea, no
+  issue has been triaged, no worker Job has been created — so the admission policy, though
+  now provably applied and Enforce, has still never refused or admitted a real Job. The
+  network policies have not carried traffic.
+- **I did not re-run the merge gate against `main` after the merge.** This branch's own gate
+  run is the evidence for this change; the merged state's is CI run on PR #57.

+title: new-peer.sh refused the first VPN address because its duplicate check matched its own commented-out example
+---
+
+## What changed
+
+The operator's first real enrolment failed:
+
+```
+$ ./infra/vpn-ingress/new-peer.sh keith-phone 2
+new-peer.sh: 10.90.0.2/32 is already allocated in platform/vpn-ingress/peers.yaml. Pick another octet.
+```
+
+**Nothing was allocated.** `peers.yaml` had zero peers — the pod's own init container reported
+`wg0.conf assembled: 0 peer(s)`. The duplicate-address check grepped the WHOLE file, and
+`peers.yaml` line 66 is a **commented-out example stanza** I wrote, containing literally
+`#   AllowedIPs = 10.90.0.2/32`. So `.2` — the first address anybody would ask for, and the one my
+own runbook uses in its example — was permanently un-allocatable, with a message asserting the
+opposite of the truth.
+
+Both halves fixed, because either alone leaves the trap half-set:
+
+- **`infra/vpn-ingress/new-peer.sh`**: the check strips comment lines before matching
+  (`grep -vE '^[[:space:]]*#' | grep -q …`). That is the correct predicate rather than a patch: a
+  real stanza's `AllowedIPs` line is never commented, while both the template and every peer's
+  `# <name> — <owner>` label always are.
+- **`platform/vpn-ingress/peers.yaml`**: the example now uses placeholders that cannot match
+  anything real — `# <device-name> — <owner>, enrolled <YYYY-MM-DD>` and
+  `AllowedIPs = 10.90.0.<octet>/32`. A future grep cannot be fooled by it either.
+
+The bug class is worth naming: **a documentation example that is byte-identical to real data will
+eventually be parsed as real data.** The same shape caused two earlier defects in this component —
+`flux-postbuild-substitution` flagged a `${...}` written inside a comment *explaining* that hazard,
+and `no-plaintext-secrets` flagged the `.sops.yaml.example` because the kustomization named it in a
+comment. Three instances now; the rule is to make examples structurally unmatchable, not merely
+commented out.
+
+No sensitive paths (`platform/vpn-ingress/**`, `infra/vpn-ingress/**`, `decisions/**`), so this
+merges on a green gate with no override.
+
+## What I verified
+
+Run in the pinned toolbox against the live tree, 2026-10-06.
+
+- **`.2` now works**, and it went through the REAL key path: `new-peer.sh keith-phone 2` rendered a
+  profile with `Address 10.90.0.2/32`, `AllowedIPs = 10.90.0.2/32` in the printed stanza, full
+  tunnel, at `.cache/wg-peers/keith-phone.conf` (0600). The throwaway keypair was deleted after.
+- **This incidentally closes a gap left open in #60**: the profile could only have been rendered by
+  deriving the server's public key via `sops -d --extract … | wg pubkey` from
+  `wg-server-key.sops.yaml` — so that pipeline is now proven **against the operator's real key**,
+  not just against a placeholder it was expected to reject.
+- **A real duplicate is still refused.** Appending an uncommented
+  `AllowedIPs = 10.90.0.5/32` stanza and asking for octet 5 produced the correct refusal; the tree
+  was restored afterwards and `git diff --stat` showed only the intended template edit.
+- **Zero active allocations remain**: `grep -vE '^[[:space:]]*#' peers.yaml | grep -c AllowedIPs`
+  → `0`.
+- **Toolbox gate**: rc 3, with `spec-immutability`, `decisions-log`, `lint`, `l0`, `render-golden`,
+  `l1` and `approval-policy` all pass; rc 3 is the two environmental skips (`gitea-settings`,
+  conformance L2/L3). **Not green. Reported as rc 3.**
+
+## What I did NOT verify
+
+- **No peer is enrolled by this branch.** The keypair I generated was a throwaway and was deleted;
+  the operator must run the script themselves, since the device's private key must exist only on
+  the device. So the end of the enrolment path — a stanza merged into `peers.yaml`, Flux rolling
+  the DaemonSet, and `wg show` listing a peer — is still unexercised.
+- **The duplicate-NAME warning** (`grep -qi "^ *# *${NAME} "`) deliberately still inspects
+  comments, because per-peer labels are comments. It is no longer tripped by the template, but I
+  did not test it against a real enrolled peer.

+title: A merged VPN peer never reached the tunnel — the peer register was a fixed-name ConfigMap, so nothing rolled the pods
+---
+
+## What changed
+
+The operator enrolled a phone, merged the peer, and **`wg show` listed no peers.** Measured on prod
+2026-10-06, with the peer already on `main`:
+
+| observation | value |
+|---|---|
+| peer stanza on `main` | present (`AllowedIPs = 10.90.0.2/32`) |
+| GitRepository artifact | `main@sha1:e1bebb8` — Flux had fetched it |
+| `vpn-ingress` Kustomization `lastAppliedRevision` | `main@sha1:5928d81` — **behind**, 10m interval |
+| live `wg-peers` ConfigMap, active `AllowedIPs` lines | **0** |
+| DaemonSet volume reference | `configMap.name: wg-peers` — a **fixed** name |
+| DaemonSet `generation` / `observedGeneration` | **1 / 1** — it had **never rolled** |
+| init container, all three pods | `wg0.conf assembled: 0 peer(s)` |
+
+The lag was only the reconcile interval. **The defect is the fixed name.** When Flux does update a
+fixed-name ConfigMap it updates it *in place*: the DaemonSet's pod template is byte-identical, so
+no rollout is triggered — and because the init container assembles `wg0.conf` **once at pod start**
+into a tmpfs, the running tunnel keeps the old peer list indefinitely. Adding or revoking a peer
+would have had **no effect at all** until something unrelated happened to restart the pods. For a
+*revocation* that is a security defect, not an inconvenience: the operator would delete a stanza,
+see a green PR, and the device would keep working.
+
+My runbook and README both asserted "PR → merge → Flux rolls the DaemonSet (~1 min)". That was
+never true.
+
+**This repo already documents the fix, and I had read the file.** `runbooks/kustomization.yaml`:
+*"The generated name carries kustomize's content hash, so editing any runbook rolls the server
+automatically and a stale projection is impossible."*
+
+So the register becomes a **content-hashed generator**:
+
+- `platform/vpn-ingress/peers.yaml` (inline ConfigMap) → **`platform/vpn-ingress/peers.conf`**, a
+  plain file, plus a `configMapGenerator` in `kustomization.yaml`. The operator's enrolled peer was
+  carried across verbatim. Every line is WireGuard config and `#` is a legal comment there, so the
+  documentation now travels *inside the mounted file* instead of in a YAML wrapper that gets
+  stripped.
+- **`namespace: vpn-ingress` added to the kustomization — REQUIRED, not tidiness.** A generated
+  ConfigMap inherits no namespace; every other object here declares `vpn-ingress`; and kustomize's
+  `nameReference` transformer will not rewrite a reference across a namespace boundary. Without it
+  the build emitted `ConfigMap wg-peers-m9kcckcb5t` while the DaemonSet still mounted the unhashed
+  `wg-peers`, which would not exist — the pods would wedge on a missing volume. I caught this only
+  by building the output and reading the volumes block.
+- **`infra/vpn-ingress/new-peer.sh`**: `PEERS_FILE` repointed to `peers.conf`, and a missing
+  register is now **fatal** instead of skipped. The old guard was
+  `[ -r "$PEERS_FILE" ] && grep …`, so after the rename the only symptom would have been
+  duplicate-address detection quietly never firing again — the silent-skip shape this repo treats
+  as a defect in its own right.
+- Stale `peers.yaml` references swept from the README, runbook, `daemonset.yaml`,
+  `networkpolicy.yaml`, the SOPS example, and the script's own **user-facing output** (it told the
+  operator to paste into "peers.yaml, under data.peers.conf", which would no longer exist).
+- The runbook gained the verification that actually distinguishes this failure — the DaemonSet's
+  `generation` must *increase* after the merge — and a troubleshooting row for `0 peer(s)` after a
+  merge.
+
+Flux's `prune: true` removes the orphaned fixed-name `wg-peers` ConfigMap on the next reconcile.
+
+No sensitive paths (`platform/vpn-ingress/**`, `infra/vpn-ingress/**`, `runbooks/**`,
+`decisions/**`), so this merges on a green gate with no override.
+
+## What I verified
+
+Built and run in the pinned toolbox, 2026-10-06 (kustomize v5.8.1 via `kubectl kustomize`).
+
+- **The reference is now rewritten end to end**: generated `ConfigMap wg-peers-m9kcckcb5t` in
+  namespace `vpn-ingress`, and the DaemonSet mounts **`wg-peers-m9kcckcb5t`**. Before adding
+  `namespace:` the same build mounted the unhashed `wg-peers` — so the namespace line is load
+  bearing, measured both ways.
+- **The hash tracks content, which is the whole mechanism.** `wg-peers-m9kcckcb5t` →
+  append a second peer → `wg-peers-dgg7ht9c74` → restore → `wg-peers-m9kcckcb5t`. Deterministic
+  and reversible, so an edit necessarily changes the pod template.
+- **The operator's enrolled peer survived the file conversion byte-for-byte**: the active stanza in
+  `peers.conf` (`PublicKey = pBRSHrRy…`, `AllowedIPs = 10.90.0.2/32`) is identical to the one on
+  `main`, compared directly against `git show origin/main:platform/vpn-ingress/peers.yaml`.
+- **The build still emits all five objects**: Namespace, ConfigMap, Secret, DaemonSet,
+  NetworkPolicy — and the `Namespace` object's own name is still `vpn-ingress` (the namespace
+  transformer did not rewrite it).
+- **`new-peer.sh` works against the new register**: `spare-laptop 7` renders a profile and prints
+  "append this to platform/vpn-ingress/peers.conf"; `dupe 2` is **refused** because the operator's
+  real `.2` now occupies it — the first time the duplicate check has been exercised against real
+  data rather than against its own example.
+- **Toolbox gate**: rc 3, with `spec-immutability`, `decisions-log`, `lint`, `l0`, `render-golden`,
+  `l1` and `approval-policy` all pass; rc 3 is the two environmental skips. **Not green. Reported
+  as rc 3.**
+
+## What I did NOT verify
+
+- **That the roll actually happens on the cluster.** The whole point of the change is unproven
+  until Flux applies it: the success criterion is the DaemonSet's `generation` increasing and
+  `wg0.conf assembled: 1 peer(s)` in the init log, followed by `wg show` listing the peer.
+- **That the tunnel then carries traffic.** No handshake has ever been observed. The WAN
+  port-forward is reportedly configured but has never been exercised by a packet I can see, and I
+  have no off-LAN vantage point — runbook step 6 from cellular remains the only honest test.
+- **Revocation**, which is the case where this defect was a security problem. Deleting a stanza
+  should now roll the pods and drop the peer; untested.
+- **Whether the orphaned fixed-name `wg-peers` ConfigMap is actually pruned.** Reasoned from
+  `prune: true` on the Kustomization, not observed.

+title: The nodes resolve gitea to the WAN, so the failing certificate is the router's — the second node process to need the issuer pin
+---
+
+## What changed
+
+The image pull for `pm-agent` failed TLS verification, and the previous entry on this branch
+honestly recorded it as **not diagnosed**. The operator asked for the diagnosis before any
+registry design. This is it, and the fix turns out to be a pattern this repository already
+has.
+
+`infra/ansible/inventory/group_vars/k3s_prod/vars.yml` now pins
+`gitea.{{ k3s_base_domain }}` → `192.168.2.20` in `node_baseline_hosts_pins`, beside the
+Keycloak issuer pin that is there for the identical reason.
+
+**It reaches the nodes the way every other node setting in this project does — through
+Ansible, from the inventory.** Node configuration is Ansible's (and, for the dev VMs,
+OpenTofu's); nothing here touches a node by hand. For prod specifically, Ansible is the
+*only* surface: `infra/PROD-PROVISIONING.md` records that prod is 3× bare metal and that the
+dev path (OpenTofu → Proxmox VM → cloud-init) does not apply, so there is no
+cloud-init/tofu half to keep in parity for this. The one scoped, idempotent command:
+
+    cd infra/ansible && ansible-playbook playbooks/node-baseline.yml \
+      -e k3s_hosts=k3s_prod --tags hosts
+
+`--tags hosts` runs ONLY the `/etc/hosts` task, so applying this pin cannot drift any other
+baseline setting. Running the play is an operator action (it has become/root on prod), but
+the configuration itself is declared, reviewed and version-controlled — not typed on a node.
+
+The docs that described this as an undiagnosed blocker now describe the cause and the fix:
+`platform/pm-agent/README.md`, `runbooks/pm-agent.md` (its symptom row now names the pin and
+the play), and `docs/plans/pm-agent-issue-to-pr.md`.
+
+Also recorded, in the two places an operator reads when creating the credential: **the agent
+authenticates to Gitea with a local account and a scoped PAT, by decision** (operator,
+2026-10-06), not with a federated identity. Written down because the alternative looks
+obviously better until you check whether it is possible — see below.
+
+## What I verified
+
+Every step measured, read-only, in this order.
+
+**The failing certificate is the router's, not the Gateway's.**
+
+- containerd's error names TLS, not the digest: `tls: failed to verify certificate: x509:
+  certificate is not valid for any names, but wanted to match gitea.home.keithjackson.dev`.
+  "not valid for **any** names" means the presented certificate carries no SANs at all.
+- `192.168.2.20` is the shared Gateway's own LoadBalancer VIP
+  (`gateway/cilium-gateway-shared`, from the Cilium pool `192.168.2.20-30`), and its `https`
+  listener serves `*.home.keithjackson.dev` with `wildcard-home-tls`. From the operator's
+  workstation the name resolves there and serves the real Let's Encrypt
+  `CN=*.home.keithjackson.dev` with correct SANs. **So the certificate and the Gateway are
+  healthy.**
+- **The node asks a different resolver and gets a different answer.** Prod's
+  `node_baseline_dns_servers` is the LAN gateway, not Pi-hole — deliberately, as that file
+  explains. Public DNS for this zone is a CNAME to `wan.home.keithjackson.dev`: measured via
+  both `1.1.1.1` and `8.8.8.8`, `gitea.home.keithjackson.dev` →
+  `wan.home.keithjackson.dev.` → `136.51.115.252`, and the apex answers the same.
+- **That address serves a certificate with no names.** Measured from the workstation against
+  the WAN address with the right SNI:
+
+      subject=C=ZZ, ST=Somewhere, L=Unknown, O=%D342e7e6b, CN=%D
+      issuer=C=ZZ, ST=Somewhere, L=Unknown, O=%D342e7e6b, CN=%D
+      No extensions in certificate
+
+  No extensions means no `subjectAltName`, which is exactly "not valid for any names". The
+  `CN=%D` is the router's placeholder.
+
+**This repository had already measured the same thing, for Keycloak, and I did not need to
+re-derive it.** `infra/ansible/inventory/group_vars/k3s_prod/vars.yml` says, above the pin:
+"Since platform/gateway/gateway.yaml set an external-dns `target`, every public name is a
+CNAME to wan.home.keithjackson.dev = the home WAN IP. The SOHO router does NOT hairpin: from
+the LAN, WAN:443 answers with the router's own self-signed placeholder cert (measured from
+k3s-prod-2/-3 2026-10-03: `curl` exit 60, ssl_verify_result=18)." Same cause, same symptom,
+one name later. The pin exists precisely for node processes that must reach the Gateway
+directly; containerd is one, and nobody had added it.
+
+**The parity the pin has to satisfy:** `192.168.2.20` equals the live
+`GATEWAY_VIP`, and `k3s_base_domain` equals the live `BASE_DOMAIN` — both read from the
+cluster, not from the comment that claims prod serves `prod.home.keithjackson.dev` (it does
+not; `flux-system/cluster-vars` reports `BASE_DOMAIN=home.keithjackson.dev` and
+`GATEWAY_VIP=192.168.2.20`, and Ansible's `k3s_base_domain` is `home.keithjackson.dev`).
+That comment is stale history.
+
+**The credential decision, and why the obvious alternative is not available.** Gitea's API
+accepts basic auth, PATs, SSH signatures and its own OAuth2 bearer tokens; as an OAuth2
+provider Gitea implements **only the Authorization Code Grant** (plus PKCE/OIDC), so there
+is no client-credentials grant, and nothing in Gitea validates a token issued by a
+third-party OIDC provider. A Keycloak service-account token therefore cannot authenticate to
+Gitea's API or to git-over-HTTP. Read from Gitea's own documentation
+(`docs.gitea.com/development/api-usage`, `/development/oauth2-provider`), not assumed.
+
+**Gate:** `./ci/gate.sh` in the pinned toolbox from a §0 worktree — see the branch's run; rc 3
+with `gitea-settings` the only stage that did not run.
+
+## What I did NOT verify
+
+- **That the pin fixes the pull.** It is IaC, and nothing has applied it: `/etc/hosts` on the
+  nodes is written by the `node_baseline` play's `hosts`-tagged task, which is an operator
+  action. I did confirm the mechanism is not inert — `roles/node_baseline/tasks/main.yml`
+  renders `node_baseline_hosts_pins` into a marked `blockinfile` with `backup: true`, and
+  `state: absent` when the list empties, so a removed entry really leaves the node. Until that runs
+  and an image exists, "the node now reaches the Gateway" is a design claim. The evidence
+  that it *will* is the Keycloak pin working for the same cause — which I also did not
+  re-measure.
+- **Why public DNS answers at all for an `internal` service.** `catalog/gitea.yaml` sets no
+  `exposure`, so it inherits `internal`, and the renderer contract says an internal service's
+  HTTPRoute carries `external-dns.alpha.kubernetes.io/controller: none` and publishes no
+  public record. Yet `gitea.home.keithjackson.dev` resolves publicly to the WAN CNAME. I did
+  not chase that: it may be a zone-level wildcard rather than a published record, and it did
+  not change the diagnosis. It is worth someone's attention, because "internal services
+  publish no public DNS" is an L0-checked claim and this looks like a case where the *name*
+  resolves regardless of what the renderer withheld.
+- **Registry authentication.** Unchanged and still open: an unauthenticated client gets
+  nothing from this registry, and no `imagePullSecret` exists anywhere in the tree. With the
+  credential model now decided (local Gitea accounts with PATs) the shape is a
+  `dockerconfigjson` for an account whose token carries `read:package`, referenced from the
+  Deployment and the committed worker Job template — and the worker Job template's shape is
+  pinned by admission, so whether the policy should also pin `imagePullSecrets` deserves a
+  deliberate look rather than a quiet addition. Not built: minting that token is an operator
+  action, and I did not want to guess at a second credential's scope.
+- **Anything about runtime.** The image still does not exist. No dispatcher has
+  authenticated, no issue has been triaged, no worker Job has been created, and the admission
+  policy — live, `Enforce`, six rules — has still never admitted or refused a real Job.

+title: The VPN tunnel never came up — a hostNetwork pod cannot write net.ipv4.ip_forward, and wg-quick treats a failed PostUp as fatal
+---
+
+## What changed
+
+The remote-access VPN reconciled for the first time with a real server key (#60 then #62) and
+**the tunnel did not come up**. One line in my own manifest was the whole cause.
+
+Measured in the `wireguard` container on prod, 2026-10-06:
+
+```
+[#] ip link add dev wg0 type wireguard
+[#] wg addconf wg0 /dev/fd/63
+[#] ip -4 address add 10.90.0.1/24 dev wg0
+[#] ip link set mtu 1420 up dev wg0
+[#] sysctl -q -w net.ipv4.ip_forward=1
+sysctl: permission denied on key "net.ipv4.ip_forward"
+[#] ip link delete dev wg0
+**** Tunnel /config/wg_confs/wg0.conf failed, will stop all others! ****
+```
+
+Everything up to that point worked. **The cause is not a missing capability.** With
+`hostNetwork: true` the runtime mounts `/proc/sys` **read-only** in the container — confirmed in the
+pod's own `/proc/mounts`: `proc /proc/sys proc ro,nosuid,nodev,noexec,relatime` — precisely because
+those sysctls are the *host's* globals and a container must not rewrite them. `CAP_NET_ADMIN` cannot
+lift a read-only mount, so this can never succeed from here. And `wg-quick` treats any failed
+`PostUp` as fatal, so it deleted the interface it had just finished building.
+
+**The line was never needed.** `node_baseline` writes `net.ipv4.ip_forward=1` to
+`/etc/sysctl.d/99-k3s-cilium.conf`, and reading the value from inside the pod returns `1`. I had
+written the header comment *correctly* — "ip_forward is ALREADY 1 on these nodes … so no pod sysctl
+is needed" — and then emitted the sysctl anyway, justified in its own comment as "re-asserted so
+this component does not silently depend on another role's sysctl file surviving". That defensive
+re-assertion is the entire outage. **The lesson is narrow and reusable: in a hostNetwork pod,
+verify host state, never write it.**
+
+Fix:
+
+- **`platform/vpn-ingress/daemonset.yaml`**: the `PostUp = sysctl …` line is gone, replaced by a
+  **read** in the init container — `grep -qx 1 /proc/sys/net/ipv4/ip_forward` — which fails closed
+  with a message naming the `node_baseline` role. Reading `/proc/sys` is permitted; only writing is
+  not. Fail-closed still matters: a tunnel that comes up but cannot forward would satisfy every
+  probe in this component and silently drop every client's traffic.
+- The header bullet that said "no pod sysctl is needed" now also says **do not attempt one**, with
+  the mechanism, so the next author does not re-add it for the same reason I did.
+- The `securityContext` comment claimed NET_ADMIN was for "create the wg0 link, set the host sysctl,
+  and write the netfilter rules". The middle clause was false; corrected.
+- The image's `chown: … Operation not permitted` startup run — plus its own "Permissions could not
+  be set … we will not provide support for it" — is now documented as **expected and harmless**, in
+  both the manifest and the runbook, so nobody chases it. Capabilities are dropped to `NET_ADMIN`
+  only, so its s6 init has no `CAP_CHOWN`; `/config` is a writable tmpfs, everything runs as root,
+  and `wg-quick` proceeds past it (as it did here — the failure was 30 lines later).
+- **`runbooks/vpn-remote-access.md`**: a "what a healthy start looks like" block with the real log
+  lines; `ip_forward is 0` added to the init-failure table; and the note that `0/1 Running` with

+
+No sensitive paths: `platform/vpn-ingress/**`, `runbooks/**` and `decisions/**` only. This merges on
+a green gate with no override.
+
+## What I verified
+
+Live prod, read-only, 2026-10-06. **Four questions this component's design rested on are now
+measured rather than assumed — three went the right way, one was the defect above.**
+
+- **The GitOps path is proven end to end.** `Kustomization vpn-ingress` `lastAppliedRevision:
+  main@sha1:cf7d5e4` equals the GitRepository artifact revision. The Secret carries
+  `kustomize.toolkit.fluxcd.io/name: vpn-ingress`, so Flux delivered it.
+- **SOPS decryption works, proven by digest rather than by eye.** The value in
+  `platform/vpn-ingress/wg-server-key.sops.yaml` on `main`, decrypted, is 44 bytes, is **not** the
+  placeholder, and **`wg pubkey` accepts it**. Its SHA-256 equals the SHA-256 of the live Secret's
+  decoded `data.privatekey` (`d7c8f8de6f252649…` both sides). No key material was printed at any
+  point — lengths, booleans and digests only.
+- **The `wg pubkey` guard fired correctly, and its `ENC[` branch was never needed.** During the
+  kubelet window before the updated Secret propagated, all three pods reported *"It is still the
+  committed REPLACE-ME PLACEHOLDER"* — the guard distinguishing a stale/unfilled value from
+  ciphertext, exactly as designed. It cleared on its own once the mount refreshed; **a transient
+  `REPLACE-ME` CrashLoop for a minute or two after the key PR merges is expected, not a fault.**
+- **The kernel module reaches the pod**: `ip link add dev wg0 type wireguard` succeeded and
+  `/proc/modules` lists `wireguard`. So the `node_baseline` addition works and `CAP_SYS_MODULE` is
+  correctly not required.
+- **`allowPrivilegeEscalation: false` does NOT break the image's s6 init** — the container reaches
+  `wg-quick` normally. The flag stays; the fear recorded in #55 is closed.
+- **The iptables backends MATCH, which was my single biggest documented doubt.** The image ships
+  `iptables v1.8.13 (nf_tables)` via `/usr/sbin/xtables-nft-multi`, and Debian 13 is nf_tables. The
+  nightmare case — rules accepted into a table the kernel never consults, so handshakes succeed and
+  every forwarded connection hangs — cannot occur on this pairing.
+- **`net.ipv4.ip_forward` is `1`** in the host netns the pod shares, and `/proc/sys` is `ro` there.
+  Both read directly from the pod.
+- **Toolbox gate** from an isolated worktree: **rc 3**, with `spec-immutability`, `decisions-log`,
+  `lint`, `l0`, `render-golden`, `l1` and `approval-policy` all **pass**; rc 3 is the two
+  environmental skips (`gitea-settings`, conformance L2/L3). **Not green. Reported as rc 3.**
+
+## What I did NOT verify
+
+- **That the tunnel now comes up.** This fix has not reconciled. The next reconcile is the test, and
+  its success criterion is specific: pods `1/1 Running`, and `wg show` reporting `interface: wg0`
+  with `listening port: 51820`.
+- **That the MASQUERADE and FORWARD rules actually apply.** They are the next statements after the
+  one that failed, so **they have never executed**. The backends matching (above) removes the worst
+  failure mode but proves nothing about the rules themselves. First check after the pods go Ready:
+  `iptables -t nat -S POSTROUTING | grep 10.90.0.0/24` on a node.
+- **Anything about client traffic.** Still zero peers enrolled, still no WAN port-forward, still no
+  off-LAN vantage point. The VPN has carried no packet.
+- **Whether the transient `REPLACE-ME` window has an upper bound.** It cleared within ~2 minutes
+  here; I did not determine the kubelet refresh behaviour, so a longer stall after a key change is
+  uncharacterised.
+- **The `sops set` hand-off command**, still. The operator filled the key in by their own route
+  (#62), so the exact quoting I documented inside `dev.sh run bash -c` remains unexercised.

+title: Repoint bulk NFS at the TrueNAS (192.168.2.30); the PVs must be recreated, not reconciled
+---
+
+## What changed
+
+Both ZFS pools were physically moved off the Proxmox host onto a standalone TrueNAS Community
+Edition at **192.168.2.30**, which sits on prod's own `192.168.2.0/24`. `BULK_NFS_SERVER` moves from
+`192.168.2.102` (the pfSense DNAT prod used to mount through) to `192.168.2.30`.
+
+- `clusters/prod/kustomization.yaml` — `BULK_NFS_SERVER` → `192.168.2.30`. The comment block that
+  justified the DNAT, and the "NOT YET DECIDED / THIS PLACEHOLDER IS LOAD-BEARING" banner, are
+  replaced with the measured export configuration and the recreate requirement below.
+- `clusters/base/cluster-vars.yaml` — base default `192.168.1.9` → `192.168.2.30`. That host no
+  longer exists.
+- `clusters/dev/kustomization.yaml` — same; marked explicitly **inert**, since dev is decommissioned
+  and its nodes are gone. It carries the real address only so nothing in the tree renders a dead one.
+- `docs/BULK-NFS-STORAGE.md` — §1 and §5 rewritten for TrueNAS (exports, service settings, the ZFS
+  `sharenfs` properties that had to be cleared, and the ACL hazard); §7 rewritten now that the
+  placeholder is gone; §9 retargeted from dev to prod; **new §10** documents the PV
+  delete-and-recreate. §2/§3/§4/§6 are unchanged by the move.
+- `catalog/qbittorrent.yaml`, `platform/monitoring/node-pressure-dashboard.yaml` — two comment/prose
+  references to `192.168.2.102` as the live export address.
+
+**The headline operational fact: repointing this knob is NOT a plain reconcile.** A bound PV's NFS
+source is immutable, so Flux's apply fails rather than updating and the pods keep their old, dead
+mount. The five PVs must be deleted and recreated. That sequence is §10 and is an operator action;
+it is **not** performed by this PR.
+
+## What I verified
+
+**On the NAS (192.168.2.30), measured 2026-10-07 by the operator at my request:**
+
+- `zfs list` — `Storage` → `/mnt/Storage`, `Storage/plex` → `/mnt/Storage/plex`,
+  `Storage/nextcloud` → `/mnt/Storage/nextcloud`. The PV paths resolve unchanged.
+- Ownership intact: `/mnt/Storage/plex`, `tv/`, `downloads/`, `movies/`,
+  `downloads/complete/`, `nextcloud/nextcloud/` all `drwxr-xr-x 1000:3000`. `movies/` 1171 entries
+  and `tv/` 107, against 1165 / 107 measured on Proxmox.
+- `acltype=nfsv4` (SCALE's built-in default, `SOURCE: default`), `aclinherit=passthrough`, and no
+  non-trivial ACLs — mode bits still govern.
+- Three stale `sharenfs` dataset properties (`plex`, `nextcloud`, `docker-volumes`) carried over from
+  Proxmox; cleared with `zfs inherit`, re-checked empty.
+- `exportfs -v`: both shares to `192.168.2.10/.11/.12` with `sec=sys,secure,root_squash,no_all_squash`,
+  `rw` on plex and `ro` on nextcloud.
+- `/proc/fs/nfsd/versions` → `+3 +4 +4.1 +4.2`, so the PVs' `nfsvers=4.1` negotiates.
+- **A defect was found and fixed during setup:** the plex share listed `192.168.2.13` — an address no
+  node holds — and so omitted `192.168.2.12` (k3s-prod-3). Corrected and re-verified.
+
+**From the cluster:**
+
+- Node InternalIPs are `192.168.2.10/.11/.12` (`kubectl get nodes`), confirming `.13` was wrong.
+- All five NFS PVs currently name `192.168.2.102`.
+- `192.168.2.30:2049` and `:111` accept connections; `192.168.2.102:2049` does not.
+- **`spec.nfs` immutability, by server-side dry-run** — this is the finding that shapes the change:
+  `spec.persistentvolumesource: Forbidden: spec.persistentvolumesource is immutable after creation`.
+- The pods report `Ready` while their mounts are dead: a `stat /media` answers from attribute cache,
+  but a `readdir` blocks indefinitely (the PVs mount `hard`). Hence "scale to zero first" in §10.
+
+**Gate:** see the PR; run in the pinned toolbox from this worktree.
+
+## What I did NOT verify
+
+- **Nothing has mounted 192.168.2.30.** No pod has touched the new server — the PVs still point at
+  the old address and cannot be updated in place. Every §9 probe (numeric-id passthrough, the uid-1000
+  write, the hardlink/EXDEV check, Plex's read-only posture) is **outstanding**, not passing. The
+  equivalents passed against the old host on 2026-09-12; that is not evidence about this one.
+- **The §10 sequence is reasoned, not executed.** Retain + the renderer's pre-set `claimRef` are read
+  from the manifests and from `catalog/render.py`; I have not watched a PVC rebind after a PV delete
+  in this cluster.
+- **`root_squash` is a behaviour change from the Proxmox export**, which carried `no_root_squash`. The
+  argument that nothing needs root on the tree (LSIO drops to 1000; the images chown only their
+  Longhorn `/config`; both subPath directories already exist at 0755) is reasoned from the images and
+  the measured permissions. It has not been exercised. If a mount or subPath resolution fails with
+  EACCES, Maproot `root:root` reproduces the old export and is the first thing to try.
+- **Whether NFSv3 can be disabled.** Enabled Protocols is `NFSv3, NFSv4`; the PVs only need v4.1, so
+  narrowing would close the rpcbind/mountd/statd surface. Not done — it is a change to make after the
+  cutover is proven, not during it.
+- **Whether pfSense / the legacy stack is actually retired.** I measured only that
+  `192.168.2.102:2049` stopped answering. The other legacy consumers of these datasets
+  (`192.168.1.6`, `10.123.1.10`, `192.168.1.18`) were dropped from the new exports; if any is still
+  live, it has lost access. Not checked.
+- **L2/L3 conformance.** `vars.CLUSTER_AVAILABLE` is unset, so CI proves the L0/L1 offline subset
+  only. Nothing in the gate exercises an NFS mount.

+tcp/2049 did not traverse that, so prod mounted through a DNAT at `192.168.2.102`, and which address
+belonged in `BULK_NFS_SERVER` depended on an undecided operator choice. Both pools were physically
+moved on 2026-10-07 (`docs/plans/proxmox-to-n5-air-migration.md`, Phase C/D) and all of that is

 ### 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

-**pfSense DNATs the existing port-forward WITHOUT source NAT.** Connecting from this workstation

-### `Storage/plex` — append the six k3s node addresses to the existing `rw=` list
+Per-node addresses rather than `@192.168.2.0/24`, following the precedent of the old host. A `/24`
+would work and would survive adding a node; it also grants the whole subnet.
+
+**All three nodes must appear on BOTH shares.** Any media pod can be scheduled on any node, so a
+missing node is a latent failure, not an immediate one: it surfaces the first time a pod reschedules
+there, as `access denied by server while mounting`, with the cause weeks stale. One was caught
+exactly this way during setup — the plex share listed `192.168.2.13`, an address no node holds, and
+so was missing `192.168.2.12` (k3s-prod-3). Nothing was failing at the time.
+
+### The option flags ARE the permission contract
+
+| flag | why it matters here |
+|---|---|
+| **`no_all_squash`** | The one the whole model rests on. Client uids pass through untouched, so the arrs' `PUID=1000` arrives as the owner of a `0755 1000:3000` tree. In the UI this is **Mapall User/Group left EMPTY** — setting either squashes every client to one identity and erases the reader/writer distinction entirely. |
+| **`sec=sys`** | AUTH_SYS. Numeric uid/gid, not Kerberos principals. §6 is only true because of this. |
+| **`root_squash`** | Maproot left empty. The Proxmox export carried `no_root_squash`; **nothing here needs it** — every write to the tree happens after the LSIO drop to uid 1000, and the images only chown their Longhorn `/config`. This is a deliberate tightening over the old export, not parity. |
+| **`rw` / `ro`** | The archive's read-only posture is **server-enforced**, as it was before. The media tree cannot get the same treatment — see below. |
+| **`secure`** | Reserved source ports required; "Allow non-root mount" off. The kubelet mounts as root from a reserved port and does not need the exception. |
+
+**Plex's read-only posture is still a CLIENT-side guarantee.** Plex is ro and the arrs are rw, but
+all four can land on any node, so the server sees the same three source addresses for all of them
+and cannot distinguish the reader from the writers. `spec.nfs.readOnly: true` on `plex-media` plus
+the volumeMount flag is the whole enforcement. Unchanged by the move; an honest limitation, not an
+oversight. If it ever needs to be server-enforced, the lever is a dedicated node pool for Plex.
+
+### Service settings that are NOT obvious from the export list
+
+- **Enabled Protocols must include NFSv4** (above).
+- **Require Kerberos for NFSv4: off.** The numeric AUTH_SYS pass-through is the model.
+- **Manage Groups Server-side: off.** This is `rpc.mountd --manage-gids`: the server *discards the
+  client's supplied group list* and looks that uid's groups up in TrueNAS's own user database
+  instead. With no local uid 1000 defined, the arrs' `PGID=3000` would simply vanish. Writes would
+  survive anyway — uid 1000 **owns** the tree, so the owner bits grant access without the group —
+  but it is a free way to lose group semantics.
+- **NFSv4 DNS Domain: blank.** It only feeds `idmapd.conf`, which numeric mapping bypasses.
+- **Bind IP 192.168.2.30** means loopback does not answer: check with `showmount -e 192.168.2.30`,
+  not `localhost`.
+
+There is **no** "NFSv3 ownership model for NFSv4" control on current TrueNAS — it was an older
+TrueNAS/CORE option, and no replacement is needed: on a Linux client against a Linux server over
+AUTH_SYS, both the `nfs` and `nfsd` modules default to `nfs4_disable_idmapping=Y`, so NFSv4 carries
+raw numeric ids rather than `user@domain` principals. §9's `ls -n` probe is how you confirm it.

+The tree's ownership **is** the access story (§6), and TrueNAS offers two ways to destroy it

-Nextcloud consumes this dataset from k3s, so the export itself can refuse writes. Even a

+`Storage/plex` carries `acltype=nfsv4` (SCALE's built-in default, `SOURCE: default`) and
+`aclinherit=passthrough` (inherited). Measured 2026-10-07: the directories carry **trivial ACLs
+only** — `nfs4xdr_getfacl` shows just `owner@`/`group@`/`everyone@` matching the mode — so `0755
+1000:3000` governs exactly as it did under Proxmox.

-**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.
+- **Stay out of the dataset's Edit Permissions / Edit ACL screen.** On an `acltype=nfsv4` dataset
+  that is a full ACL editor, and its presets write *real* NFSv4 ACLs, recursively if permitted.
+  There is no undo.
+- `aclinherit=passthrough` means a single ACL written at `/mnt/Storage/plex` would be **inherited by
+  everything created under it afterwards** — the blast radius is the whole future library, not one
+  directory.
+- Note GNU `ls`'s `+` marker is **not** a reliable ACL indicator here: it looks for a POSIX ACL
+  xattr, and this dataset stores NFSv4 ACLs elsewhere. Use `nfs4xdr_getfacl`.

-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.
+`xattr=on` rather than `sa` is a performance detail, not a permissions one, and changing it would
+not affect existing files.

+## 10. Repointing BULK_NFS_SERVER means DELETING AND RECREATING THE PVs
+
+**A bound PersistentVolume's NFS source is immutable.** Measured by server-side dry-run on
+2026-10-07:
+
+```
+$ kubectl patch pv sonarr-media --type=json --dry-run=server \
+    -p '[{"op":"replace","path":"/spec/nfs/server","value":"192.168.2.30"}]'
+The PersistentVolume "sonarr-media" is invalid: spec.persistentvolumesource: Forbidden:
+  spec.persistentvolumesource is immutable after creation
+```
+
+Note the pairing with §7: `spec.nfs.server` is **unvalidated at create** (any string is accepted and
+the PVC binds) and **immutable at update**. So editing `BULK_NFS_SERVER` alone does not fail loudly
+and does not work either — Flux's apply errors on the five PVs and the pods keep their previous,
+now-dead mount.
+
+This is safe to do because `persistentVolumeReclaimPolicy: Retain` means deleting a PV never touches
+the data, and `catalog/render.py` emits a **pre-set `claimRef`** on each one, so a recreated PV
+rebinds its own PVC with no manual step.
+
+**Operator sequence** (mutating `kubectl` is an operator action, not an agent action):
+
+```sh
+# 1. Stop the consumers. This also releases the hung hard-mounts against the old server:
+#    the pods report Ready, but any real I/O on /media blocks indefinitely once 2049 stops
+#    answering, because the PVs mount `hard`.
+for ns in plex sonarr radarr qbittorrent nextcloud; do
+  kubectl --context k3s-prod -n $ns scale deploy --all --replicas=0
+done
+
+# 2. Delete the five PVs. Retain + no live claim means nothing is reclaimed or erased.
+kubectl --context k3s-prod delete pv plex-media sonarr-media radarr-media \
+  qbittorrent-downloads nextcloud-legacy-archive
+
+# 3. Let Flux reconcile the revision carrying BULK_NFS_SERVER=192.168.2.30, which recreates them.
+#    Confirm .status.lastAppliedRevision matches the GitRepository artifact before continuing.
+
+# 4. Bring the consumers back, then run every probe in §9.
+```
+
+The PVCs pass through `Lost` between steps 2 and 3; that is expected and resolves when the PV with
+the matching `claimRef` reappears. If a PVC is still `Lost` after Flux reconciles, the PV name or
+its `claimRef` namespace does not match — do **not** delete the PVC to "fix" it.

+## Why the agent authenticates to Gitea with a local account and a PAT
+
+Not Keycloak, and that is a decision rather than an omission (operator, 2026-10-06): the
+agents only ever talk to Gitea, so a local Gitea account with a scoped personal access token
+is the whole requirement, and it is drastically simpler than federating a machine identity.
+
+It is also what Gitea can actually do. Keycloak service accounts were considered and are not
+available for this: Gitea's API accepts basic auth, PATs, SSH signatures and **its own**
+OAuth2 bearer tokens, and as an OAuth2 provider Gitea implements **only the Authorization
+Code Grant** — there is no client-credentials grant, and nothing in Gitea validates a token
+issued by a third-party OIDC provider. So a Keycloak service-account token cannot
+authenticate to Gitea's API or to git-over-HTTP at all. Keycloak remains what it is for human
+access: the browser login source registered on Gitea (`catalog/gitea.yaml`).
+
+What still matters, and is enforced by the hand-off rather than by Keycloak: **the account
+must not be an administrator** — `infra/gitea/approval-policy.json` authorises
+`/approve-override` on live repository permission alone, so an admin-permission bot could
+waive the sensitive-path human review on its own pull request.

@@ -31,6 +50,36 @@ Both are deliberate, and both fail **visibly** rather than silently:
   `infra/agent/build-image.sh` (which verifies it and refuses to push), push it as the
   operator, then update **both** places with the digest `podman push --digestfile` returned,
   in one pull request. Until then: `ImagePullBackOff`.
+
+   **Two things have to be true before any digest will pull, and neither is declared in this
+   repository.** Both were measured after PR #57 merged — this service is the first workload
+   in the cluster ever to reference the in-cluster registry, so nothing had exercised the
+   path. Details and the exact commands:
+   [`decisions/2026-10-05-pm-agent-registry-pull-prereq.md`](../../decisions/2026-10-05-pm-agent-registry-pull-prereq.md).
+
+   - **The nodes resolve the registry hostname to the WAN, so the TLS they fail to verify is
+     the router's — DIAGNOSED 2026-10-06, and fixed in this change.** containerd pulls as a
+     *node* process, so it resolves through the node's public upstreams
+     (`node_baseline_dns_servers` = the LAN gateway) rather than through Pi-hole. The public
+     answer for every name in this zone is a CNAME to `wan.home.keithjackson.dev` — the WAN
+     IP — which this router does not hairpin; it answers :443 with its own placeholder
+     certificate `CN=%D` carrying **no extensions, therefore no SANs**, which is precisely
+     `x509: certificate is not valid for any names`. The Gateway, the wildcard certificate
+     and the digest were never implicated. The fix is the pin this repository already uses
+     for the Keycloak issuer, for the identical reason: `gitea.{{ k3s_base_domain }}` is now
+     in `node_baseline_hosts_pins` — node configuration is Ansible's, declared in the
+     inventory, never typed on a node. Apply it scoped to that one task:
+     `cd infra/ansible && ansible-playbook playbooks/node-baseline.yml -e k3s_hosts=k3s_prod
+     --tags hosts`.
+   - **The pull is still unauthenticated** once the node reaches the right endpoint. An
+     unauthenticated client gets nothing from this Gitea's registry, and there is no
+     `imagePullSecret` anywhere in the tree. Consistent with the agent credential decision
+     (local Gitea accounts with PATs), the fix is a `dockerconfigjson` for a local Gitea
+     account whose token carries `read:package`, referenced from the Deployment and the
+     committed worker Job template — not built yet, because minting that token is yours.

+right way; one was a defect in my own manifest.
+
+| question | answer |
+|---|---|
+| Does the **kernel module** reach the pod? | **Yes.** `ip link add dev wg0 type wireguard` succeeds, and `/proc/modules` lists `wireguard`, after the `node_baseline` run. `CAP_SYS_MODULE` is correctly not needed. |
+| Does `allowPrivilegeEscalation: false` break the image's **s6 init**? | **No.** The container reaches `wg-quick` normally. The flag stays. |
+| Is the image's **iptables** backend compatible with the host's? | **Yes — both nft.** The image ships `iptables v1.8.13 (nf_tables)` via `xtables-nft-multi`, and Debian 13 is nf_tables. This was the documented worst fear (rules silently landing in a table the kernel does not consult); it is closed. |
+| Can the pod set **`net.ipv4.ip_forward`**? | **No, and it must not try.** `/proc/sys` is mounted **read-only** under `hostNetwork` (`proc /proc/sys proc ro,…`), because those are the host's globals; `sysctl -w` fails with EPERM whatever the capabilities. A failed `PostUp` is fatal to `wg-quick`, so this one line took the whole tunnel down. The node already has it set to `1`; the init container now **verifies** rather than writes. |

The dev value is marked inert (dev is decommissioned); it carries the real address only so nothing in the tree renders a host that no longer exists. THE OPERATIONAL POINT, and why this is not just a value change: a bound PersistentVolume's NFS source is immutable. Server dry-run, 2026-10-07: spec.persistentvolumesource: Forbidden: spec.persistentvolumesource is immutable after creation so Flux's apply FAILS rather than updating, and the pods keep their old, dead mount. The five PVs must be deleted and recreated -- safe, because Retain never touches data and render.py emits a pre-set claimRef so each PV rebinds its own PVC. The sequence is docs/BULK-NFS-STORAGE.md section 10 and is an OPERATOR action; this commit does not perform it. Pairs with the hazard already on the page: spec.nfs.server is unvalidated at create (any string binds) and immutable at update. A wrong value is accepted silently and then cannot be corrected in place. docs/BULK-NFS-STORAGE.md: sections 1 and 5 rewritten for TrueNAS -- the measured exports, the service settings that decide whether uid 1000 survives the wire, the three stale ZFS sharenfs properties that had to be cleared, and the ACL hazard (acltype=nfsv4 + aclinherit=passthrough means one click in the ACL editor propagates to the whole future library). Section 7 rewritten now that the placeholder is gone, section 9 retargeted from dev to prod, section 10 new. Sections 2/3/4/6 are unchanged by the move.

Measured on prod 2026-10-06 with the peer already on main: live wg-peers ConfigMap, active AllowedIPs .. 0 DaemonSet volume reference ................. configMap.name: wg-peers (FIXED) DaemonSet generation/observedGeneration .... 1 / 1 (never rolled) init container, all three pods ............. "0 peer(s)" Part of it was just the 10m reconcile interval. The defect is the fixed name: Flux updates a fixed-name ConfigMap IN PLACE, so the pod template is byte-identical, so no rollout is triggered -- and the init container assembles wg0.conf ONCE at pod start into a tmpfs, so the running tunnel keeps the old peer list indefinitely. Adding or revoking a peer had no effect until something unrelated restarted the pods. For a REVOCATION that is a security defect, not an inconvenience: delete a stanza, see a green PR, device keeps working. The runbook and README both claimed "PR -> merge -> Flux rolls the DaemonSet". Never true. And this repo already documents the fix, in a file I had read -- runbooks/kustomization.yaml: "The generated name carries kustomize's content hash, so editing any runbook rolls the server automatically and a stale projection is impossible." So: peers.yaml (inline ConfigMap) -> peers.conf (plain file) + a configMapGenerator. The operator's enrolled peer is carried across verbatim. Every line is WireGuard config and `#` is a legal comment there, so the documentation now lives inside the file that is actually mounted. `namespace: vpn-ingress` on the kustomization is REQUIRED, not tidiness: a generated ConfigMap inherits no namespace, everything else here declares vpn-ingress, and kustomize's nameReference will not rewrite across a namespace boundary -- without it the build mounts the unhashed name and the pods wedge on a missing volume. Caught only by building the output and reading the volumes. new-peer.sh: PEERS_FILE repointed, and a missing register is now FATAL rather than skipped -- the old `[ -r "$PEERS_FILE" ] && grep ...` guard meant that after the rename the only symptom would have been duplicate detection quietly never firing again. Stale peers.yaml references swept from six files including the script's own user-facing output. Verified: the DaemonSet now mounts wg-peers-m9kcckcb5t; the hash tracks content (edit -> dgg7ht9c74 -> restore -> m9kcckcb5t); the enrolled peer is byte-identical to main's; and `new-peer.sh dupe 2` is now correctly refused by the operator's real allocation. No sensitive paths; merges on a green gate. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>	2026-10-06 02:55:59 -05:00

Fixed on both sides, because either alone leaves the trap half-set: * the check strips comment lines before matching, which is the correct predicate rather than a patch: a real stanza's AllowedIPs line is never commented, while the template and every peer's `# <name> — <owner>` label always are. * the example now uses placeholders that cannot match anything real (`10.90.0.<octet>/32`, `<device-name>`), so a future grep cannot be fooled by it either. The bug class is worth naming: a documentation example that is byte-identical to real data will eventually be parsed as real data. This is its third instance in this component -- flux-postbuild-substitution flagged a `${...}` written inside a comment explaining that hazard, and no-plaintext-secrets flagged the .sops.yaml.example because a kustomization named it in a comment. Make examples structurally unmatchable, not merely commented out. Verified by running it: .2 now renders a profile (via the real `sops -d \| wg pubkey` path, which this also proves against the operator's actual key for the first time), and an uncommented duplicate stanza is still correctly refused. No sensitive paths; merges on a green gate. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>	2026-10-06 02:28:37 -05:00

jakman85andClaude Opus 5	5c43fbac65	fix(vpn-ingress): stop trying to set net.ipv4.ip_forward — a hostNetwork pod cannot, and wg-quick dies on a failed PostUp gate / gate (pull_request) Successful in 1m51s Details gate / conformance (pull_request) Has been skipped Details The tunnel never came up on its first reconcile with a real key. One line of my own manifest was the whole cause. Measured on prod 2026-10-06: [#] ip link add dev wg0 type wireguard <- fine [#] wg addconf wg0 /dev/fd/63 <- fine [#] ip -4 address add 10.90.0.1/24 dev wg0 <- fine [#] ip link set mtu 1420 up dev wg0 <- fine [#] sysctl -q -w net.ipv4.ip_forward=1 sysctl: permission denied on key "net.ipv4.ip_forward" [#] ip link delete dev wg0 ** Tunnel failed, will stop all others! ** Not a missing capability: with hostNetwork the runtime mounts /proc/sys READ-ONLY (confirmed in the pod's /proc/mounts), because those sysctls are the HOST's globals. CAP_NET_ADMIN cannot lift a read-only mount, so the write can never succeed here -- and wg-quick treats a failed PostUp as fatal, so it deleted the interface it had just built. The line was never needed. node_baseline already sets ip_forward=1, and reading it from the pod returns 1. My header comment said exactly that ("so no pod sysctl is needed") and then emitted the sysctl anyway, justified as "re-asserted so this component does not silently depend on another role's sysctl file". That defensive re-assertion is the entire outage. In a hostNetwork pod: VERIFY host state, never write it. Replaced with a read in the init container -- `grep -qx 1 /proc/sys/net/ipv4/ip_forward` -- failing closed with a message naming the node_baseline role. Still fail-closed on purpose: a tunnel that comes up unable to forward satisfies every probe here and silently drops all client traffic. Also documents, in the manifest and the runbook, that the image's `chown: Operation not permitted` run and its "we will not provide support for it" warning are expected and harmless -- capabilities are dropped to NET_ADMIN so its s6 init has no CAP_CHOWN, /config is a writable tmpfs, everything runs as root, and wg-quick proceeds (it did; the failure was 30 lines later). Three other unknowns closed by the same reconcile, now recorded in the README: the kernel module reaches the pod (ip link add type wireguard works, no CAP_SYS_MODULE needed); allowPrivilegeEscalation:false does NOT break the s6 init; and the image's iptables is nf_tables (xtables-nft-multi) matching Debian 13, which closes the worst documented fear -- rules landing in a table the kernel never consults. No sensitive paths; merges on a green gate with no override. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>	2026-10-06 01:30:08 -05:00

jakman85andClaude Opus 5	90a79d29d3	docs(node): name the exact Ansible command that applies the pin, not 'run the play' gate / gate (pull_request) Successful in 1m52s Details gate / conformance (pull_request) Has been skipped Details Node configuration in this project is Ansible's — declared in the inventory, reviewed, version-controlled — and for prod it is the ONLY surface: infra/PROD-PROVISIONING.md records prod as 3x bare metal with the dev OpenTofu -> Proxmox -> cloud-init path explicitly not applying, so there is no tofu/cloud-init half to keep in parity for an /etc/hosts pin. The pin was already in the right place; what the docs lacked was the command. All four places now carry the scoped, idempotent one: cd infra/ansible && ansible-playbook playbooks/node-baseline.yml \ -e k3s_hosts=k3s_prod --tags hosts --tags hosts runs ONLY the /etc/hosts task, so applying this pin cannot drift any other baseline setting. Also verified the mechanism is not inert, which is the failure mode this repo keeps meeting: roles/node_baseline/tasks/main.yml renders node_baseline_hosts_pins into a marked blockinfile with backup: true, and state: absent when the list empties — so a removed entry really does leave the node.

jakman85andClaude Opus 5	523a463fd7	fix(node): pin gitea to the Gateway VIP — containerd was resolving it to the non-hairpinned WAN gate / gate (pull_request) Successful in 1m52s Details gate / conformance (pull_request) Has been skipped Details The pm-agent image pull failed TLS verification, and the previous entry on this branch recorded it honestly as not diagnosed. Diagnosed now, and it is not about the image. containerd pulls as a NODE process, so it resolves through node_baseline_dns_servers (the LAN gateway, deliberately not PiHole) and gets the public answer: a CNAME to wan.home.keithjackson.dev -> 136.51.115.252, measured via both 1.1.1.1 and 8.8.8.8. This router does not hairpin, so WAN:443 answers with its own placeholder certificate — measured with the right SNI from the workstation: subject=C=ZZ, ST=Somewhere, L=Unknown, O=%D342e7e6b, CN=%D No extensions in certificate No extensions means no subjectAltName, which is exactly 'certificate is not valid for any names'. Meanwhile 192.168.2.20 IS the shared Gateway's VIP and its https listener serves the real Let's Encrypt *.home.keithjackson.dev. The Gateway, the wildcard cert and the digest were never implicated — only the node's answer. This file already documents the identical failure for the Keycloak issuer, measured from k3s-prod-2/-3 on 2026-10-03 (curl exit 60, ssl_verify_result=18), and already carries the mechanism that fixes it. gitea is simply the second node process to need it; containerd is a node process and nobody had added it. An operator must run the node_baseline play. Also records, where an operator reads them, that the agent authenticates to Gitea with a local account and a scoped PAT by decision — and why the federated alternative is not merely unchosen but unavailable: Gitea implements only the Authorization Code Grant and validates no third-party OIDC token, so a Keycloak service-account token cannot authenticate to its API or to git-over-HTTP.

jakman85andClaude Opus 5	a209a618fd	fix(pm-agent): the agent is IN the cluster — one git host, the cluster-local service name gate / gate (pull_request) Successful in 1m50s Details gate / conformance (pull_request) Has been skipped Details An in-cluster consumer reaches a service by its *.svc.cluster.local name, which is by design a different path from how a client outside the cluster reaches the same service. pm-worker's host allowlist accepted TWO values: the cluster-local name and the external hostname gitea.home.keithjackson.dev. The second is removed. It was never needed — nothing sets it — it would route in-cluster traffic out through the Gateway and back for no reason, and as an ACCEPTED value it widened the allowlist to a host reachable over the namespace's world:443 egress rule, which is precisely the injection shape the allowlist exists to refuse. probe-validation.sh now pins that: 20 refusals, including the external hostname, the cluster-local name over https, and the cluster-local name on the wrong port. Also corrects a remark in the handoff entry: I cited cluster-vars' GATEWAY_VIP (192.168.1.53) as suspicious next to the nodes' 192.168.2.x. That was noise — those base cluster-vars values are dev-era leftovers for a decommissioned cluster and say nothing about prod. None of the measured facts depended on it.

jakman85andClaude Opus 5	6253d546f8	docs(pm-agent): the registry cannot be pulled from yet — name both prerequisites where the operator reads them gate / gate (pull_request) Successful in 1m50s Details gate / conformance (pull_request) Has been skipped Details pm-agent reconciled exactly as designed after #57: Flux applied main@sha1:95597bd to platform-config, pm-agent and apps-wave-0 (all Ready), the ClusterPolicy pm-agent-job-shape is live with Enforce + failurePolicy Fail and all six rules, SOPS decryption works through the new overlay patch (checked by key names and value lengths, never values), and pm-agent-worker really is bound to nothing. Measuring it turned up two prerequisites for the NEXT operator step that nothing in this repository declares, and that #57's handoff could not have known — it listed the image pull as unverified, and that is exactly where it bit: - the nodes cannot verify the registry's TLS certificate (containerd: 'x509: certificate is not valid for any names'), while the same name serves a healthy Let's Encrypt wildcard from the LAN. A correct digest fails identically; - an unauthenticated client gets nothing from this Gitea's registry (its anonymous token carries no access scope) and no imagePullSecret exists anywhere in the tree. Not specific to pm-agent: conformance-runner shares the registry path and has never been pulled either. The dispatcher is the first workload in the cluster ever to reference it. Documentation only — no manifest, no policy, no code. Both fixes need an operator action and one of them is a posture decision, so the docs present both rather than pick.
