 # .gitea/workflows/gate.yml — the ENFORCED PR merge gate (Phase 6, WS-GITOSS).
 #
 # This is the LIVE gate wired to the in-cluster Gitea Actions runner (ns gitea-actions,
-# Docker executor + DinD). It invokes the AGGREGATE merge gate — `make -C ci gate` — so CI
-# runs BYTE-FOR-BYTE the same command a human runs in the devcontainer (R-TEST-02): the
-# runner just installs the pinned tools from ci/versions.env first. `make -C ci gate`
-# (ci/gate.sh) runs every stage in order — spec-immutability, lint, Kyverno L0,
-# render==golden, L1 offline render — and applies the R-TEST-03 decision, printing
-# "MERGE GATE: PASS" / "MERGE GATE: BLOCKED". It is the single required status check on
-# `main` (see branch protection). A non-zero exit fails the job, so a BLOCKED gate blocks
-# the merge.
+# Docker executor + DinD). It invokes the AGGREGATE merge gate — `./ci/gate.sh`, which is
+# exactly what `make -C ci gate` runs, so CI and the devcontainer gate the same way
+# (R-TEST-02): the runner just installs the pinned tools from ci/versions.env first (and see
+# below for why the script, not `make`, is invoked here). It runs every stage in order —
+# spec-immutability, lint, Kyverno L0, render==golden, L1 offline render — and then applies the
+# R-TEST-03 decision, printing
+# "MERGE GATE: PASS" (0) / "BLOCKED" (1) / "UNDETERMINED" (3) / "NOT APPLICABLE" (0). It is the
+# single required status check on `main` (see branch protection). A non-zero exit fails the job,
+# so a BLOCKED gate blocks the merge.
+#
+# WHY THIS STEP DECLARES GATE_STRICT_SKIPS AND TOLERATES EXIT 3 (2026-09-13). A SKIPPED stage is
+# never green, and since 2026-09-13 gate.sh refuses to print PASS when one did not run (it used to
+# print "— not green" and then "MERGE GATE: PASS", exit 0 — fail-open in the gate itself). Two
+# kinds of non-run must be told apart HERE, in the caller, because only the caller knows which
+# environment it is:
+#   * a pinned tool missing or a seam unwired ON THIS RUNNER is a DEFECT — the toolchain is
+#     installed for us two steps up. GATE_STRICT_SKIPS=true DECLARES that (no env sniffing, no
+#     "does this look like CI?" heuristic) and makes those skips exit 1: untolerated, job fails.
+#   * spec-immutability CANNOT be verified here at all: the spec repo is a separate repo and is
+#     not checked out into this runner (SPEC_REPO_SLUG unwired; blueprint in merge-gate.yaml). It
+#     is the ONLY skip that can still reach exit 3 under strict skips, which is what makes
+#     `|| [ "$?" -eq 3 ]` a narrow, reviewed tolerance rather than a blanket one. The log still
+#     says UNDETERMINED and names R-TEST-06 as unverified. Wire the spec checkout (or set
+#     REQUIRE_SPEC_VERIFICATION=true) and this tolerance should be deleted.
+# Called DIRECTLY, not through `make`: GNU make reports any recipe failure as its own exit 2, so
+# `make -C ci gate || [ "$?" -eq 3 ]` would see 2 and fail the job. Same reason the
+# spec-immutability pre-step below calls the script directly.
 #
 # The cluster-gated L2/L3 conformance stage SKIPS honestly here (exit 3, surfaced not faked
-# — HARD RULE 4) because this runner declares no cluster: `make -C ci gate` does not set
-# CLUSTER_AVAILABLE, so gate.sh reports the touched requirements UNVERIFIED without blocking
-# Phase-0/6 static work. L2/L3 run as an IN-CLUSTER Chainsaw Job (its own scoped SA; CI holds
+# — HARD RULE 4) because this runner declares no cluster: nothing here sets CLUSTER_AVAILABLE,
+# so gate.sh reports the touched requirements UNVERIFIED — and NAMES that declared gap in its
+# PASS headline — without blocking Phase-0/6 static work. L2/L3 run as an IN-CLUSTER Chainsaw Job (its own scoped SA; CI holds
 # no broad kubeconfig) driven by the separate `conformance` job below.
 #
 # NOTE (R-TEST-06 / gate-semantics): spec-immutability is ALSO surfaced as its own explicit
 # early step (below) so its result is a distinct, tolerant status in the Gitea UI; gate.sh
-# re-runs it as its first stage, which is the authoritative one. `make -C ci gate` here is
-# the byte-identical laptop gate; the extra pre-step is a read-only git-diff check and is
+# re-runs it as its first stage, which is the authoritative one. The gate step below is the
+# same script the laptop runs; the extra pre-step is a read-only git-diff check and is
 # purely additive. The full pipeline blueprint (spec-checkout, per-layer jobs, decision job)
 # is retained dormant in merge-gate.yaml.

+# RECOVERY BASELINE — the COMPLETE Cloudflare record set for zone `keithjackson.dev`
+# as it stood IMMEDIATELY BEFORE feat/externaldns-scope-public-only is applied.
+#
+# WHY THIS FILE EXISTS. The branch that adds it changes which resources ExternalDNS considers,
+# and ExternalDNS runs `policy: sync` — a record whose source stops matching is DELETED, not
+# merely left alone. That is a one-way, outward-facing operation against a live authoritative
+# zone, so the pre-state is captured and committed BEFORE the change lands, and any record the
+# reconcile removes can be restored by hand from this file. It is the same discipline as
+# dns-before.txt / dns-verify.txt / dns-post-l2.txt beside it, applied to a destructive-capable
+# change rather than to a migration.
+#
+# CAPTURED 2026-09-14 from the Cloudflare API (GET /zones/<id>/dns_records, all pages) using the
+# SOPS-encrypted token in platform/externaldns/cloudflare-api-token.sops.yaml. Read at the
+# AUTHORITY, not through a resolver: 1.1.1.1 served stale answers for minutes after the
+# 2026-09-13 apex flip and must not be trusted for this. `dig` is on the host but NOT in the
+# devcontainer, which has previously produced false "no records" readings — the API is the only
+# reading that is both complete and authoritative.
+#
+# FORMAT (5 fields, `|`-separated) — wider than the sibling files on purpose: a restore needs the
+# TTL and the proxy flag, not just the value.
+#
+#   <type>|<name>|<content>|<ttl>|<proxied>
+#
+# ttl 1 = Cloudflare "Automatic". proxied false = DNS-only (grey cloud), which every record here
+# is; a restore that flips one to proxied would put Cloudflare's edge in front of a LAN address.
+#
+# 39 records. 36 of them are ExternalDNS-managed (18 A + their 18 `a-`-prefixed TXT registry
+# entries), every one registered `external-dns/owner=prod` — i.e. THIS cluster owns them, which
+# is why this cluster's reconcile is able to delete them. The remaining 3 belong to the legacy
+# non-k3s stack and carry NO TXT registry entry, so no owner id claims them and ExternalDNS
+# cannot touch them regardless of what this branch does:
+#
+#   *.keithjackson.dev            -> 136.51.115.252   legacy stack (the zone wildcard)
+#   brickbreak.keithjackson.dev   -> 20.236.242.14    unrelated, off-prem
+#   dev.brickbreak…               -> 20.236.242.14    unrelated, off-prem
+#
+# NOTE there is NO `*.home.keithjackson.dev` wildcard in the zone any more (the comment in
+# clusters/prod/kustomization.yaml still says the zone has both wildcards; it does not, as of
+# this capture). A single-label wildcard does not match two labels, so `*.keithjackson.dev` does
+# NOT cover `<svc>.home.keithjackson.dev`: when a specific `<svc>.home` record is removed, that
+# name goes to NXDOMAIN publicly rather than falling back to the legacy IP. That is the intended
+# end state for `internal` services and it is also precisely why Pi-hole must already be
+# answering the LAN authoritatively before this branch merges.
+#
+# WHICH OF THESE THIS BRANCH DELETES — the 12 rows for the six `exposure: internal` catalog
+# services (jackett, pihole, qbittorrent, radarr, semaphore, sonarr): each one's A record and its
+# `a-`-prefixed TXT registry entry. Nothing else. Verified live on prod against the deployed
+# v0.21.0 with a throwaway hostname before any of this was authored: adding the annotation to an
+# HTTPRoute that already had a published record produced
+# `action=DELETE record=... type=A` and `action=DELETE record=a-... type=TXT` one reconcile
+# interval (~60s) later, and nothing else in the zone moved.
+#
+# TO RESTORE ONE ROW BY HAND (both halves, or ExternalDNS will not recognise the record as its
+# own): recreate the A record with its value/ttl/proxied from this file, then recreate the
+# matching `a-<name>` TXT with its content VERBATIM — the `heritage=…,external-dns/owner=prod,
+# external-dns/resource=…` string is what re-establishes ownership. An A record restored without
+# its TXT is unowned and will not be reconciled; a TXT restored with a wrong `resource=` value
+# points the registry at a source object that does not exist.

+# CLAUDE.md — how work lands in this repo
+
+Read this before doing anything durable. It is the delivery contract for AI coding
+sessions and agents. `DECISIONS-LOG.md`'s last entry is the current PM handoff and
+takes precedence on *what* to work on; this file governs *how* it lands.
+
+## 1. Never push to `main`. Ever.
+
+Every durable change reaches `main` exactly one way:
+
+    branch  ->  push the branch  ->  open a PR  ->  CI gate green  ->  human approval  ->  merge
+
+There is no other path. Specifically:
+
+- **Do not `git push origin main`.**
+- **Do not `git push origin HEAD:main`.** Same thing wearing a hat.
+- **Do not merge your own PR.** A human approves and clicks merge.
+- **Do not `kubectl apply` / `edit` / `patch` a durable change.** Flux reconciles `main`;
+  anything applied by hand is drift that the next reconcile reverts or, worse, adopts.
+
+> **Many runbooks under `runbooks/` still say `git push origin main` IS the deploy.**
+> That wording is **stale** — it predates the PR flow. It describes what Flux does
+> (main is what the cluster follows), not what you are permitted to do. Honour this
+> file, not that line. Fixing those runbooks is tracked work.
+
+## 2. Enforcement is currently WEAKER than this rule. Follow the rule anyway.
+
+Verified against the live Gitea on 2026-09-29:
+
+| Expected | Actual |
+|---|---|
+| `main` protected, direct push rejected | **No branch protection.** `protected: false`, `user_can_push: true` |
+| PR blocked until the gate passes | **`enable_status_check: false`**, `status_check_contexts: []` |
+| Gate runs on every PR | **Fixed 2026-09-29.** Runner `incluster-dind` is online; `gate / gate (pull_request)` runs and passes in ~1m30s–2m |
+| Approval required before merge | **`required_approvals: 0`** |
+
+So nothing mechanically stops you from pushing to `main` right now. **That is a gap
+being closed, not permission.** `DECISIONS-LOG.md` (2026-08-31) claimed the gate was a
+"required status check" with a runner online; neither was true, which is how this went
+unnoticed for a month. The runner half is now genuinely fixed and observed green. The
+protection half is not — see `infra/gitea/`.
+
+**Consequence for you:** CI now runs, but it does not yet *block* anything. Always run
+the toolbox gate yourself and quote its numbers. Never describe a PR as "green" on the
+strength of a check you have not seen report — and note that a **skipped** Gitea job
+reports as `success`, so a green tick is not by itself evidence that anything ran.
+
+## 3. Gate before you push
+
+    ./infra/devcontainer/dev.sh run bash -c './ci/gate.sh'
+
+Exit codes are a contract — do not flatten them:
+
+| rc | Meaning |
+|---|---|
+| 0 | PASS |
+| 1 | BLOCKED — something failed |
+| 3 | UNDETERMINED — a stage did not run. **Never report this as green.** |
+
+`spec-immutability` reaches rc 3 whenever the sibling spec repo is not checked out
+beside this one; that single skip is expected and tolerated. Any *other* skip is a
+real gap in your run.
+
+**Never gate on the host.** `promtool` and `kustomize` are not on the host `$PATH`,
+so checks SKIP and you get a false rc 3. Only the pinned toolbox result counts.
+
+### Running the gate from a git worktree
+
+Two unrelated failures, both with known workarounds — put both in any agent brief:
+
+1. **`dev.sh` refuses to start:** `infra/ansible/.cache/prod.kubeconfig` is untracked
+   and exists only in the main checkout. Do **not** copy it (it is a credential).
+   Use `DEV_KUBECONFIG=/dev/null` — the gate contacts no cluster, so L2/L3 scaffold-skip
+   normally.
+2. **Every `git` call inside the container fails:** a worktree's `.git` is a pointer to a
+   gitdir outside the mounted root. `dev.sh` takes no extra-mount flag, so inject one via
+   the `ENGINE` hook — a shim that intercepts `run` and re-execs
+   `podman run -v /path/to/main/.git:/path/to/main/.git:ro "$@"`. A traceback in
+   `tracked_files()` is this bug, not a broken tree.
+
+## 4. Branch naming
+
+Use `feat/`, `fix/`, `docs/`, `chore/`. Note that `.gitea/workflows/gate.yml`'s **push**
+trigger lists `feature/**` — not `feat/**` — so branch pushes get no fast-feedback run.
+The `pull_request` trigger fires regardless of branch name, so the PR gate is unaffected.
+
+## 5. Cluster access
+
+`kubectl` does not work on the operator workstation; the toolchain lives only in the
+pinned container. Always name the context explicitly:
+
+    ./infra/devcontainer/dev.sh run bash -c 'kubectl --context k3s-prod get nodes'
+
+`dev.sh` merges both clusters and picks a current-context **per invocation**; that
+default has already changed once. Never rely on it. Do not run two `dev.sh`
+invocations concurrently.
+
+**Mutating `kubectl` and `flux reconcile` are operator actions, not agent actions.**
+
+## 6. Secrets
+
+- **Never `sops -d` a file into a terminal, a log, or a transcript.**
+- **Never print a Secret's `.data`/`.stringData`** when checking whether it exists —
+  list key names or object names only. A password has been leaked into a transcript
+  this way before.
+- Encrypted files are `*.sops.yaml` or live under `secrets/`. The root `.sops.yaml` is
+  the single creation-rules file; do not add a second one in a subtree.
+- A short-lived credential (e.g. a plex.tv claim token, ~minutes) cannot survive the PR
+  flow. Do not design around committing one — read the expiry from the issuing page and
+  treat a burnt token as free to retry.
+
+## 7. Before you finish
+
+Append a handoff entry to `DECISIONS-LOG.md` describing what you changed, what you
+verified, and what you did **not** verify. State gaps plainly — an honest
+"UNVERIFIED" is worth more than an optimistic "green", and this repo has already been
+burned by the difference.

+
+**DR restore is proven on prod.** `R-STATE-03` reads `proven` in `--status` as of 2026-09-14 —
+the first requirement in this repo to reach that state. Both of its verifiers are recorded:
+`dr-restore` (L3, run `20260914T021505Z-24b8111`, sentinel `DR_RESTORED_FROM_OFF_CLUSTER_BACKUP_OK`)
+and `placeholder-guard-coupling` (L0). The L3 drill seeds a canary on the replicated `longhorn`
+class, backs the namespace and volume data up off-cluster, **destroys every in-cluster copy**
+(namespace, PVC and PV), restores into a clean namespace, and asserts the restored PVC binds a
+*different* PersistentVolume — so an in-cluster survival cannot pass as a restore.
+
+**What remains for Phase 7:** `R-STATE-02` (`node-loss`) is still proven only on the decommissioned
+dev cluster. That drill takes a real node down on a live cluster, so it is a deliberate, scheduled
+exercise rather than something to run in passing.
+
+Read `--coverage-only` and `--status` as two different questions; the earlier `PROVEN: 0` was not a
+bug but the honest answer, because proofs are claims about a specific tree on a specific cluster.

+# -------------------------------------------------------------------------------------------
+# This file used to say `Local`, justified as "preserves the LAN client source IP and keeps the
+# VIP pinned to the node running the VM (also what L2 announcement does)". BOTH HALVES OF THAT
+# WERE FALSE ON THIS CLUSTER, and the second one took the UniFi controller off the LAN entirely.
+#
+# 1) L2 ANNOUNCEMENT DOES NOT FOLLOW THE BACKEND. Cilium's L2 announcer elects one lease holder
+#    per Service among the nodes matching the CiliumL2AnnouncementPolicy `default-l2` — which
+#    matches ALL linux nodes — and it does NOT filter that set by which nodes hold a backend.
+#    MEASURED on prod 2026-09-14: the unifi VM ran on k3s-prod-1 while BOTH
+#    `cilium-l2announce-unifi-unifi-l4-tcp` and `-udp` were held by k3s-prod-2. With `Local`, an
+#    announcing node that holds no backend has nowhere to send the packet and answers ICMP port
+#    unreachable. 192.168.2.21:8443, :8080 and :11443 were dead from the LAN for up to 8 days
+#    (the leases were 8 days old); the operator's controller UI and device inform path were down.
+#    It does NOT self-heal: the lease holder keeps RENEWING after the backend moves, so only
+#    deleting the Lease forces a re-election — and that re-election is random, so it can pick a
+#    backend-less node again. See apps/wave-0/pihole-dns.yaml, which hit this first and is the
+#    reference implementation this file now follows.
+#
+# 2) `Local` WAS NEVER PRESERVING THE CLIENT IP HERE ANYWAY — this is a KubeVirt VM. The
+#    interface in 30-virtualmachine.yaml is `masquerade: {}`, which is KubeVirt's NAT binding: it
+#    SNATs everything from the virt-launcher pod into the guest over a private link, so the UniFi
+#    controller has always seen the pod-side masquerade gateway as the source, never the LAN
+#    client. There is a SECOND translation below the Service, and it already destroyed the very
+#    thing `Local` was being kept for. So the client-IP cost of this change is ZERO for UniFi:
+#    it is giving up an address the guest could not see in the first place.
+#
+#    Nothing UniFi depends on breaks: device identity in the adoption/inform flow is the device
+#    MAC (and the device reports its own IP inside the inform payload), not the packet source,
+#    and guest-portal authorization runs on the gateway appliance, not on this controller.
+#
+# `Cluster` makes EVERY node able to serve the VIP by forwarding to wherever the VM runs, which
+# is what makes this survive a reschedule and a rebuild.
+#
+# NO CHANGE IS NEEDED IN 40-networkpolicy.yaml, AND THAT WAS VERIFIED RATHER THAN ASSUMED.
+# Under `Cluster` the forwarded second hop is sourced from the ingress node and carries Cilium's
+# reserved `remote-node` identity. pihole-dns.yaml has to name `remote-node` explicitly in its
+# CiliumNetworkPolicy — but that is because its policy deliberately omits `cluster`.
+# unifi-allow-l4-ingress admits `cluster`, and Cilium's `cluster` entity SUBSUMES `remote-node`
+# (along with host/init/unmanaged). Confirmed on prod 2026-09-14 by dumping the endpoint's
+# datapath policy map (`cilium-dbg bpf policy get`) while the CNP was in its unmodified state:
+# `reserved:remote-node` was already an Allow on the L4 ports. Adding `remote-node` to that rule
+# would be a no-op, so it is deliberately NOT added here — do not "fix" it.
+#
+# NO loadBalancerSourceRanges HERE, DELIBERATELY — and this is where this file departs from
+# pihole-dns.yaml. PiHole added `loadBalancerSourceRanges: [${LAN_CIDR}]` because it was giving
+# up a restriction it actually had and genuinely needed to be LAN-only. These Services never had
+# a source restriction at all (unifi-allow-l4-ingress admits `world`), so `Cluster` removes no
+# protection and there is nothing to compensate for. Adding a LAN-only filter during an outage
+# fix would be a NEW restriction that could silently break a remote site's device informing over
+# WAN — trading this outage for a subtler one. If UniFi should be LAN-only, that is its own
+# change, made deliberately and tested against the device fleet.

+
+## What is actually wrong (2026-09-14)
+
+The earlier note in this file said "UOS is NOT installed; the guest is a bare, prepped Ubuntu".
+That was wrong, and acting on it would have meant reinstalling over a working controller.
+
+Evidence, all read-only, from the live cluster:
+
+| Claim | How it was checked | Result |
+|---|---|---|
+| UOS is installed | `kubectl -n unifi logs virt-launcher-unifi-… -c guest-console-log` | the current boot starts **`uosserver.service` — UniFi OS Server Service** and **`uosserver-updater.service`** |
+| …and it is a real install, not a stub | KubeVirt guest-agent `filesystemlist` subresource | `/` is **6.3 GB used of 40 GB** — a bare Ubuntu cloud image with our packages is ~2 GB |
+| the guest has no IP | `kubectl -n unifi get vmi unifi -o json` → `.status.interfaces` | `enp1s0`, `linkState: up`, **no `ipAddress` field at all**; the `kubectl get vmi` IP column is empty |
+| …confirmed at the link layer | `kubectl -n unifi exec virt-launcher-… -c compute -- ip neigh` | **`10.0.2.2 dev k6t-eth0 FAILED`** — the guest does not answer ARP for its masquerade address |
+| the ports are dead end-to-end | `/dev/tcp` probes from inside virt-launcher, to the pod IP **and** to `10.0.2.2` directly | 11443 / 8443 / 8080 / **22** all refused — i.e. the VIP and the CNP are exonerated |
+
+So the controller is installed and its units start; nothing downstream of the guest's own network
+stack can work. The interface was fine at boot (the console log reaches `network-online.target` at
+~10s and cloud-init completes at 18.5s), so the address was lost afterwards — the obvious suspect is
+UOS taking over host networking, but **that has not been proven and cannot be, from outside the
+guest.** Diagnosing it needs a shell, which is the second problem below.
+
+**There is currently no way into this guest.** The shipped cloud-init installs no SSH key and sets
+no password, so the stock `ubuntu` account is locked and a serial console reaches a login prompt
+nobody can answer. SSH would not rescue it either: the masquerade interface forwards **only** the
+ports declared in `30-virtualmachine.yaml`, and 22 is not one of them — the probe above shows the
+guest RSTs on 22 exactly as it does on 11443. Closing that hole is what `console-password` in the
+new Secret is for.

-### Cloud-init delivery — two constraints learned the hard way
+### Cloud-init delivery — three constraints, all measured on the deployed KubeVirt (v1.9.0)

-1. **KubeVirt caps inline `userData` at 2048 bytes.** The original rich cloud-init (full Podman
-   prep + `install-uos` helper) blew past it. A `userDataSecretRef` was tried, then reverted; the
-   shipped config is a **minimal ~1.1 KB inline `userData`**. Keep additions small or move to a
-   Secret deliberately.
-2. **`apps-vms` must NOT use `postBuild.substituteFrom`.** Flux variable substitution rewrote
-   `$`-bearing text inside the cloud-init payload and **corrupted it**. `clusters/base/apps-vms.yaml`
-   therefore carries no `substituteFrom` — unlike every app wave. Do not "restore" it for consistency.
+1. **Inline `userData` is capped at 2048 bytes.** MEASURED, not quoted: a server-side dry-run apply
+   of an otherwise-identical VM accepted 2048 bytes and rejected 2049 with *"cloudInitNoCloud
+   userdata exceeds 2048 byte limit. Should use UserDataSecretRef for larger data."* The shipped
+   payload is ~1.45 KB. The API field for the escape hatch is spelled **`secretRef`** (the Go name
+   is `UserDataSecretRef`); `userDataSecretRef` is not a YAML key and trying it will silently
+   validate as an unknown field.
+2. **The firmware UUID is the cloud-init instance-id, and editing `userData` alone changes
+   nothing.** The NoCloud seed's `instance-id` is exactly
+   `spec.template.spec.domain.firmware.uuid`, which KubeVirt's webhook stamps onto the **VM object**
+   (so it survives restarts), and cloud-init's NoCloud datasource compares it to the guest's DMI
+   product UUID. Same id → cached datasource restored, new payload never read, `write_files` and
+   `runcmd` skipped. This is why the previously shipped "unattended install" could never have taken
+   effect on a second boot. The UUID is now **pinned in git**, with bumping it as the documented way
+   to force a re-run. See the long comment in `30-virtualmachine.yaml`.
+3. **`apps-vms` DOES use `postBuild.substituteFrom`.** This file used to say it must not — that has
+   been false since 2026-08-31, when `${UNIFI_L4_VIP}` landed in `50-service-l4.yaml`. Flux's
+   envsubst therefore runs over the cloud-init payload, and the escape contract in
+   `clusters/base/apps-vms.yaml` is in force. Bare `$name` and `$(cmd)` are left alone (verified
+   against the live VMI's rendered userData); brace-form shell expansion must be escaped; an
+   indexed expansion is a hard error that fails the whole Kustomization.

 ## L4 exposure design (the hard part)

 The shared Gateway is L7 HTTPS only (`:443` host-routed). It **cannot** carry raw TCP `8080`/`6789`
 or any UDP (`3478`/`10001`) — exactly the ports adoption rides. So:

 - **One VIP, two Services.** `unifi-l4-tcp` + `unifi-l4-udp` share a single LoadBalancer IP via
-  Cilium `lbipam.cilium.io/sharing-key: unifi`, pinned to **`192.168.1.54`** (`lbipam.cilium.io/ips`).
-  The VIP is pulled from the existing `default-pool` (192.168.1.53–.60) and **ARP-announced on the
-  flat LAN by the existing `default-l2` CiliumL2AnnouncementPolicy** — no new Cilium config.
+  Cilium `lbipam.cilium.io/sharing-key: unifi`, pinned through `${UNIFI_L4_VIP}`
+  (`lbipam.cilium.io/ips`) — **192.168.2.21 on prod**. The VIP comes from the existing
+  `default-pool`, whose live prod block is **192.168.2.20–192.168.2.30** with **192.168.2.20 held by
+  the shared Gateway** (`cilium-gateway-shared`), and is ARP-announced on the flat LAN by the
+  existing `default-l2` CiliumL2AnnouncementPolicy — no new Cilium config. (The `192.168.1.53–.60`
+  / `.53` figures this section used to quote were **dev** addressing and are gone; dev has been
+  decommissioned. Neighbours in the prod pool today: `.22` crafty, `.23` pihole-dns.)
 - `selector: kubevirt.io/vm=unifi` → the virt-launcher pod; the VM's `masquerade` iface forwards the
-  declared ports into the guest. `externalTrafficPolicy: Local` preserves LAN client source IP.
- **Device-adoption story:** point devices' **inform host** at the VIP (`http://192.168.1.54:8080/inform`)
-  — via the controller's *Override inform host* setting, `set-inform` on the device, or DHCP option 43.
-  Because the VIP is L2-announced on the devices' own subnet (192.168.1.0/24), unicast inform + STUN
-  reach it. **Limitation:** broadcast-based L2 auto-discovery (10001/udp) does **not** cross the pod
-  masquerade boundary, so zero-touch "device just appears" adoption is unreliable — expect to use
-  explicit inform. Devices on other VLANs must route to the VIP and be inform-pointed anyway.
- **Reusable pattern (== the deferred `minecraft` :25565 problem):** L4-only workload → Cilium

+- **`externalTrafficPolicy: Cluster`, corrected 2026-09-14 after an 8-day LAN outage.** This file
+  used to advertise `Local` "to preserve the LAN client source IP". Both halves were false here:
+  Cilium's L2 announcer elects a lease holder without regard to which node holds a backend (the
+  leases sat on `k3s-prod-2` while the VM ran on `k3s-prod-1`, so `Local` had nowhere to forward),
+  and KubeVirt's `masquerade` binding had already NATed the client IP away before the guest ever saw
+  it. The full reasoning — including why `40-networkpolicy.yaml` needs no `remote-node` entry and
+  why no `loadBalancerSourceRanges` was added — is in `50-service-l4.yaml`.
+- **Device-adoption story:** point devices' **inform host** at the VIP
+  (`http://192.168.2.21:8080/inform`) — via the controller's *Override inform host* setting,

-**UI access:** `https://unifi.home.keithjackson.dev:11443` (A record → VIP). The port-less
-`https://unifi.home.keithjackson.dev` via the Gateway is optional and needs a BackendTLSPolicy
-(UOS is HTTPS-only on 11443) — see `90-httproute-optional.yaml`.
+**UI access:** `https://unifi.home.keithjackson.dev:11443`. That name resolves to the VIP and not to
+the Gateway on purpose: both `platform/coredns/coredns-custom.yaml` (in-cluster) and
+`apps/wave-0/pihole.yaml` (LAN split-horizon) carve `unifi.${BASE_DOMAIN}` out of the
+zone-wide `${GATEWAY_VIP}` answer and point it at `${UNIFI_L4_VIP}`. `${BASE_DOMAIN}` on prod is the
+apex `home.keithjackson.dev` (confirmed live in the `cluster-vars` ConfigMap) after the 2026-09-13
+flip, so this hostname is current, not a dev leftover.
+
+## The operator's one field — installing UOS without a shell
+
+`unifi-uos-installer.sops.yaml` is a SOPS-encrypted Secret with two keys. KubeVirt mounts it into
+the guest as a read-only iso9660 disk labelled `UOSDATA` (one file per key), and an in-guest
+`uos-install.service` reads it **on every boot**:
+
+```bash
+sops apps/vms/unifi/unifi-uos-installer.sops.yaml    # fill installer-url and/or console-password
+git commit && git push                               # merge to the branch prod's Flux tracks
+kubectl -n unifi delete vmi unifi                    # `running: true` recreates it; no virtctl needed
+kubectl -n unifi logs -f $(kubectl -n unifi get pod -l kubevirt.io=virt-launcher -o name | head -1) \
+  -c guest-console-log                               # watch the boot + the install, read-only
+```
+
+Design notes that matter if you change this:
+
+- **The Secret is a disk, not `cloudInitNoCloud.secretRef`.** `secretRef` would lift the 2048-byte
+  cap but would move the whole cloud-config into ciphertext: unreviewable in diffs, invisible to the
+  L0 dollar-collapse guard, and still subject to Flux's envsubst (which runs over **decrypted**
+  resources) — the exact shape of the 2026-09-13 `nextcloud-db` incident. Script in plaintext,
+  operator values in SOPS.
+- **A URL change needs no UUID bump.** The disk is rebuilt from the Secret on every VMI start and
+  the systemd unit re-reads it every boot. Only a change to the cloud-init payload itself needs the
+  firmware-UUID bump.
+- **`install-uos` will not reinstall over a working controller.** It exits as soon as systemd knows
+  a `uosserver.service`, with `/var/lib/uos-installed` as a weaker second guard. Given the live
+  guest already has UOS, this guard is the difference between "safe to merge" and "destroys the
+  controller on next boot".
+- **`apps-vms` had no SOPS `decryption` stanza** — this is the first encrypted content under
+  `apps/vms/`, so the stanza was added to both `clusters/dev/kustomization.yaml` and
+  `clusters/prod/kustomization.yaml`. Without it kustomize hands Flux the raw SOPS document and the

-1. **Unattended install (HIGH) — STILL OPEN. This is the blocker.** The installer is a **signed,
-   account-tied** URL that **rotates/expires** (cannot be committed) and is documented as
-   **interactive** (no official silent flag). The shipped cloud-init had to be cut to ~1.1 KB for
-   the inline `userData` limit, so the `install-uos` helper is **no longer baked into the guest**.
-   **Decision needed:** operator runs the install by hand at bring-up (current de-facto answer), or
-   invest in a verified silent path (Secret-delivered cloud-init + a fetched-at-boot URL).
-2. **CDI http import (MEDIUM) — RESOLVED in practice.** The import succeeded (first http/qcow2 CDI
+1. **The guest lost its IP (HIGH) — THE LIVE BLOCKER, and it needs the operator.** Diagnosis
+   requires a shell, which requires `console-password` above plus one restart. First things to run
+   on the console: `ip -4 a`, `networkctl status enp1s0`, `journalctl -u systemd-networkd`,
+   `ls /etc/netplan`, and `systemctl status uosserver`. A plain restart may well restore DHCP on its
+   own (the address survived the first ~34h of this boot's life), but that would hide the cause, so
+   capture the state before rebooting a second time if you can.
+2. **Unattended install (MEDIUM) — mechanism shipped, end-to-end run NOT witnessed.** See the
+   install-method section: no official silent flag exists, `yes y | <installer> install` is the
+   convergent community practice, and it has not been executed on our guest. Treat the first real
+   install as something to watch on the console log, not as a fire-and-forget.
+3. **CDI http import (LOW) — RESOLVED in practice.** The import succeeded (first http/qcow2 CDI
   import on this cluster). Still no checksum on an http source, and the URL tracks a *moving*
   Ubuntu 24.04 build — pin a dated build dir if reproducibility matters. Needed two cluster-level
   fixes (`nonroot-devices`, `longhorn-scratch`) — see above.
-3. **Boot firmware (LOW) — RESOLVED.** Boots as shipped; running Ubuntu 24.04.4 LTS.
-4. **VIP `192.168.1.54` (LOW) — RESOLVED.** Allocated and held by both Services, inside the

   masquerade boundary — see the L4 section. Expect explicit inform-host adoption.

+6. **→ NEXT, and it is the operator's:** fill `console-password`, restart the VM once, get on the
+   console and find out why `enp1s0` has no address. Until that is fixed nothing below can pass.

+# =============================================================================
+# TEMPLATE — NOT APPLIED, NOT ENCRYPTED (.yaml.example is ignored by kustomize and never
+# auto-encrypted by SOPS). Reference scaffold + OPERATOR HAND-OFF.
+#
+# WHAT THIS IS: the two values that (a) let the UniFi VM install UniFi OS Server by itself, with
+# nobody typing commands inside the guest, and (b) give the operator a way INTO that guest at all.
+# KubeVirt mounts this Secret into the VM as a tiny read-only iso9660 disk labelled `UOSDATA` (see
+# the `uosdata` volume in 30-virtualmachine.yaml); each key below becomes a file of the same name on
+# that disk, and the in-guest `uos-install.service` reads them on EVERY boot.
+#
+# READ THIS FIRST — UOS IS ALREADY INSTALLED ON THE LIVE PROD GUEST (verified 2026-09-14, see the
+# README "What is actually wrong"). `installer-url` is therefore NOT the fix for today's outage; it
+# is the rebuild path and the "the install never happened" path. `install-uos` refuses to run the
+# installer at all while systemd knows a `uosserver.service`, so filling this in cannot clobber a
+# working controller. `console-password` IS useful today: it is the only way to get a shell.
+#
+# WHY THE URL IS BEHIND SOPS: it is obtained through the operator's own (free) Ubiquiti account
+# session at ui.com/download/software/unifi-os-server, it identifies a specific build, and it is not
+# ours to redistribute. Treat it as account-derived material, not as public configuration.
+# HONEST CAVEAT, checked 2026-09-14: the resulting `https://fw-download.ubnt.com/data/
+# unifi-os-server/<hash>-linux-x64-<version>-<uuid>.<n>-x64` URL carries NO signature query string,
+# and public community install scripts hard-code these URLs — so it does not behave like a
+# short-lived signed link. It does change every release. Encrypting it costs nothing and keeps the
+# repo's "account-derived material is not config" line clean, but do NOT design around "it expires".
+#
+# HAND-OFF STEPS (operator) — this is the whole job:
+#  (a) Sign in at https://ui.com/download/software/unifi-os-server, pick the Linux (x64) build, and
+#      copy the download link (right-click -> Copy link address). Do NOT download it here; the guest
+#      fetches it itself.
+#  (b) Open the encrypted sibling in your editor:
+#         sops apps/vms/unifi/unifi-uos-installer.sops.yaml
+#  (c) Replace the two REPLACE-ME values. Either may be left as the placeholder — the guest skips a
+#      placeholder rather than failing.
+#  (d) Save/quit (sops re-encrypts in place), commit, push, merge to the branch prod tracks.
+#  (e) Restart the VM once so the new cloud-init instance and the new disk are picked up:
+#         kubectl -n unifi delete vmi unifi        # `running: true` recreates it; no virtctl needed
+#      Watch it come up WITHOUT virtctl:
+#         kubectl -n unifi logs -f $(kubectl -n unifi get pod -l kubevirt.io=virt-launcher \
+#           -o name | head -1) -c guest-console-log
+#  (f) UI: https://192.168.2.21:11443 (prod) or https://unifi.home.keithjackson.dev:11443.
+#
+# IF YOU LATER NEED A NEW URL (new release, dead link): repeat (b)-(e). No firmware-UUID bump is
+# needed for that — the disk is rebuilt from this Secret on every VMI start and the systemd unit
+# re-reads it every boot. The UUID bump in 30-virtualmachine.yaml is only needed when the cloud-init
+# payload ITSELF changes.
+#
+# The file is already listed under `resources:` in apps/vms/unifi/kustomization.yaml, and `apps-vms`

+# CNPG METRICS-EXPORTER CONNECT RECONCILER (R-OBS-01)
+#
+# THE BUG THIS CLOSES (true positive, verified live on prod 2026-09-12, and the
+# condition platform/cnpg/alerts.yaml already recorded on BOTH clusters 2026-09-06):
+# the `nextcloud` database's ACL had been narrowed out-of-band so that PUBLIC held
+# nothing, and CNPG's metrics exporter role therefore could not even CONNECT:
+#
+#   nextcloud-db-1/-2/-3, every scrape:
+#     FATAL: permission denied for database "nextcloud" (SQLSTATE 42501)
+#     DETAIL: User does not have CONNECT privilege.
+#     msg="Error collecting user query" targetDatabase=nextcloud
+#
+# CONSEQUENCE: `cnpg_last_error` = 1 on all three instances and the ENTIRE
+# cnpg_pg_stat_* / pg_settings / pg_postmaster family MISSING for this database,
+# while the scrape target still reported up=1 — a blind spot that looks like health.
+# Measured before the fix: cnpg_pg_settings_setting had 765 series for keycloak and
+# 765 for semaphore-db and ZERO for nextcloud-db. Nextcloud's database had never
+# been monitored.
+#
+# ROOT CAUSE, AND WHY ONLY THIS DATABASE. All three Cluster specs are identical in
+# their bootstrap; the difference is entirely in the live ACL:
+#
+#   nextcloud : datacl = {nextcloud=CTc/nextcloud}          <-- explicit, no PUBLIC entry
+#   keycloak  : datacl = NULL
+#   semaphore : datacl = NULL
+#
+# A NULL datacl means "PostgreSQL defaults", which include CONNECT and TEMP for
+# PUBLIC — so keycloak and semaphore let the exporter in only by inheriting PUBLIC's
+# implicit CONNECT. On `nextcloud` something ran the equivalent of
+# `REVOKE ALL ON DATABASE nextcloud FROM PUBLIC`, which MATERIALISES datacl and
+# drops the implicit PUBLIC entry with it. That REVOKE is not in this repo and not
+# in DECISIONS-LOG.md — it was applied out of band, which is exactly why a
+# git-declared fix is needed rather than another hand-run psql.
+#
+# WHY THE GRANT IS EXPLICIT RATHER THAN "RE-GRANT CONNECT TO PUBLIC": restoring
+# PUBLIC's CONNECT would undo whatever hardening that REVOKE intended and would
+# leave the exporter depending on an implicit default again — the precise fragility
+# that broke here and that keycloak/semaphore are still relying on. Naming the
+# exporter role makes the dependency explicit and survives a future REVOKE FROM
+# PUBLIC on any of the three databases.
+#
+# WHY A CronJob AND NOT A CNPG FIELD — CNPG 1.30.0's API GENUINELY CANNOT EXPRESS
+# THIS. Checked against the live CRDs on prod:
+#   * `Database` (databases.postgresql.cnpg.io) has no database-ACL field at all.
+#     `allowConnections` is the pg_database.datallowconn FLAG (open/closed to
+#     everyone), not a per-role GRANT; its only grant/revoke verbs are the `usage`
+#     lists on `fdws` and `servers`.
+#   * `spec.managed.roles` and `DatabaseRole` manage ROLE ATTRIBUTES (login,
+#     superuser, connectionLimit, ...) plus `inRoles` MEMBERSHIP. Membership is the
+#     wrong tool: the only local role holding CONNECT here is the OWNER, so
+#     `inRoles: [nextcloud]` would hand the exporter the owner's CREATE and TEMP on
+#     the database and read/write on every application table — the opposite of
+#     least privilege, to buy one CONNECT.
+#   * `bootstrap.initdb.postInitApplicationSQL` runs ONCE, at bootstrap. It cannot
+#     repair these three already-bootstrapped instances (the actual bug), and on a
+#     FRESH cluster the grant is unnecessary anyway (datacl starts NULL). Adding it
+#     would be a second mechanism that fixes nothing this one does not.
+# So the SQL has to be applied by something, and this repo already has the pattern
+# for state Flux cannot reach: the level-triggered CronJob reconciler in
+# platform/keycloak/client-secret-reconciler.yaml, whose reasoning transfers
+# verbatim — the drifted state lives inside PostgreSQL, not in a Kubernetes object,
+# so no admission or mutation policy can see it. A one-shot Job is deliberately NOT
+# used: a completed Job is never re-run, so a DB rebuild or a PITR restore would
+# silently reopen the blind spot. A loop converges instead.
+#
+# PRIVILEGE GRANTED — EXACTLY ONE, AND NOTHING ELSE:
+#   GRANT CONNECT ON DATABASE nextcloud TO cnpg_metrics_exporter;
+# Resulting ACL entry is `cnpg_metrics_exporter=c/nextcloud` — the `c` is CONNECT;
+# there is no `C` (CREATE) and no `T` (TEMPORARY). No ownership, no superuser, no
+# write, no table or schema grants. Nothing further is needed because CNPG already
+# creates this role as a member of the built-in `pg_monitor` role (verified on all
+# three prod clusters), and pg_monitor already carries the read access every
+# collector query wants — they read pg_catalog views (pg_stat_database,
+# pg_stat_archiver, pg_settings, pg_postmaster) and no application tables. Proof
+# that CONNECT alone is sufficient: after this grant, `Error collecting user query`
+# went to ZERO on all three pods, i.e. every collector query now succeeds.
+#
+# IT RUNS AS THE DATABASE OWNER, NOT AS A SUPERUSER. `enableSuperuserAccess` is off
+# on this Cluster (there is no nextcloud-db-superuser Secret), and it stays off: the
+# owner of a database holds the grant option on that database's privileges, so
+# `nextcloud` can issue this GRANT itself. Verified live before committing, by
+# running the statement under `SET ROLE nextcloud`. Credentials come from the
+# in-namespace SOPS Secret nextcloud-db-app that already exists for the app.
+#
+# NETWORKING: nextcloud-db is intentionally NOT an app-namespace (see this file's
+# header), so Kyverno generates no default-deny baseline here and this same-namespace
+# pod -> nextcloud-db-rw:5432 connection needs no rendered allow.
+#
+# THE POD LABEL IS DELIBERATELY *NOT* app.kubernetes.io/name=nextcloud-db. That

+# PiHole DNS EXPOSURE — the LAN half of split-horizon (R-DNS-01 / R-DNS-03), and NETWORK POLICY.
+# =================================================================================================
+# HAND-WRITTEN, NOT RENDERED. This file is a non-catalog app-tier unit anchored to the `pihole`
+# ServiceDefinition and placed into wave 0 by `catalog/render.py --emit-waves` via its EXTRA_UNITS
+# table (the same mechanism gitea-actions uses). It is hand-written because the ServiceDefinition
+# schema genuinely cannot express it: schemas/servicedefinition.schema.json is
+# `additionalProperties: false` and has NO field for a type=LoadBalancer Service, for a pinned
+# lbipam VIP, for a sharing key, for loadBalancerSourceRanges, or for UDP north-south exposure at
+# all. `ingressRoutes` renders HTTPRoutes on the shared Gateway, which is an L7 HTTPS terminator and
+# cannot carry DNS. The two existing L4 workloads in this repo are hand-written for exactly this
+# reason and in exactly this shape — apps/vms/unifi/50-service-l4.yaml and
+# platform/crafty/service-l4.yaml. The ANSWERS PiHole gives are declared in the catalog
+# (catalog/pihole.yaml `env`), so the only thing living outside the catalog is the exposure the
+# schema has no word for.
+#
+# WHY THIS EXISTS AT ALL: platform/coredns/coredns-custom.yaml is explicit that its split-horizon is
+# for PODS and defers LAN clients to "PiHole split-horizon" — but PiHole served no DNS. Its Service
+# was ClusterIP with ports 80 and 4180 only. The LAN half of the split-horizon that docs/09
+# (R-DNS-03) and the README's Phase 2 row both claim simply did not exist, and LAN clients ran on
+# hand-maintained per-client dnsmasq files instead. Upstream cannot substitute: the SOHO router that
+# owns this LAN strips RFC1918 answers for public domains as rebind protection (NOERROR, ANSWER 0).
+#
+# VIP: ${PIHOLE_DNS_VIP} (cluster-vars, R-ENV-02 — dev 192.168.1.56, prod 192.168.2.23), PINNED via
+# lbipam.cilium.io/ips out of the CiliumLoadBalancerIPPool `default-pool`
+# (${CILIUM_LB_POOL_START}..${CILIUM_LB_POOL_STOP}) and ARP-announced on the flat LAN by the
+# existing CiliumL2AnnouncementPolicy `default-l2` (platform-config/cilium/*). No new Cilium config
+# is needed; these Services just consume the pool. PINNING IS NOT OPTIONAL HERE: this address is
+# typed into every LAN client's resolver configuration (or handed out by the router's DHCP), so it
+# can never be allowed to move.
+#
+# ONE VIP, TWO SERVICES: a LoadBalancer Service is single-protocol-friendly, so udp/53 and tcp/53
+# split into two Services sharing one address via lbipam.cilium.io/sharing-key — the same
+# arrangement unifi and crafty use. BOTH PROTOCOLS ARE REQUIRED, not belt-and-braces: UDP is the
+# normal query path, and TCP is what a resolver falls back to for any answer that does not fit in a
+# UDP datagram and what some clients use unconditionally. A UDP-only resolver fails intermittently
+# and confusingly.
+#
+# NO external-dns ANNOTATION, DELIBERATELY. unifi and crafty both carry
+# `external-dns.alpha.kubernetes.io/hostname` so external-dns publishes their address as a PUBLIC
+# Cloudflare record. This Service must not: `pihole-dns.${BASE_DOMAIN}` is answered by PiHole itself
+# (catalog/pihole.yaml's dnsmasq override), it is an RFC1918 address that is useless in public DNS,
+# and publishing a resolver's address in a public zone invites exactly the traffic the source-range
+# filter below exists to refuse. Internal name, internal answer, no public record — which is also
+# why this change touches nothing under platform/externaldns/.
+#
+# -------------------------------------------------------------------------------------------------
+# externalTrafficPolicy: Cluster — AND WHY IT IS NOT `Local`, WHICH IS WHAT unifi AND crafty USE.
+# -------------------------------------------------------------------------------------------------
+# `Local` is the obvious choice: it preserves the client source IP and, in theory, pins the VIP to
+# the node running the backend. The second half is NOT TRUE on this cluster, and that was measured,
+# not assumed (Cilium 1.20.1, prod, 2026-09-14):
+#
+#   * Cilium's L2 announcer elects one lease holder per Service among the nodes matching the
+#     CiliumL2AnnouncementPolicy's nodeSelector — `default-l2` matches ALL linux nodes — and it does
+#     NOT filter that candidate set by which nodes hold a backend. Created fresh, the two Services
+#     landed on DIFFERENT nodes (`cilium-l2announce-pihole-pihole-dns-tcp` -> k3s-prod-3,
+#     `-udp` -> k3s-prod-2) while the pihole pod ran on k3s-prod-1.
+#   * With `Local`, a node that announces the VIP but holds no backend has nowhere to send the
+#     packet, and the query fails with ICMP port unreachable (dig: "connection refused"). On three
+#     nodes with one replica that is a 1-in-3 chance of working, drawn independently per protocol.
+#   * It does not self-heal. The lease holder keeps RENEWING after the pod moves away: a pod
+#     rescheduled from k3s-prod-1 to k3s-prod-2 left the lease on k3s-prod-1, still renewing three
+#     minutes later, with LAN resolution dead the whole time. Only deleting the Lease forced a
+#     re-election — and that re-election is random, so it may pick a backend-less node again.
+#
+# A resolver that works one time in three and stays broken after any reschedule is not a resolver.
+# `Cluster` makes every node able to serve the VIP by forwarding to wherever the pod is, which is
+# what makes this survive a reschedule and a rebuild. VERIFIED in exactly the broken arrangement
+# above — leases on k3s-prod-2 and k3s-prod-3, pod on k3s-prod-1 — udp/53, tcp/53 and recursion all
+# answering.
+#
+# THE COST, STATED PLAINLY: Cilium runs in SNAT mode here (no `loadBalancer.mode: dsr` in
+# platform/cilium/helmrelease.yaml), so a query forwarded between nodes reaches PiHole with the
+# INGRESS NODE's address as its source, not the client's. PiHole's per-client query log, per-client
+# groups and per-client rate limiting therefore see one apparent client instead of the LAN. Two
+# consequences are handled: the rate limit is disabled in catalog/pihole.yaml (otherwise the whole
+# LAN counts as one client against PiHole's 1000-queries-per-60s default and PiHole starts
+# REFUSING), and the LAN restriction is enforced in the datapath rather than by source identity —
+# see loadBalancerSourceRanges below. The fix that would restore client IPs is `loadBalancer.mode:
+# dsr` on the Cilium HelmRelease, which is a platform-wide change with an Ansible [parity] contract
+# and would also fix the same latent defect in unifi and crafty; it belongs in its own change.
+#
+# -------------------------------------------------------------------------------------------------
+# loadBalancerSourceRanges — THE LAN RESTRICTION, ENFORCED IN THE DATAPATH.
+# -------------------------------------------------------------------------------------------------
+# Cilium enforces this list in eBPF on the ingress node, on the VIP, BEFORE load-balancing and
+# before SNAT. A packet to ${PIHOLE_DNS_VIP}:53 from outside ${LAN_CIDR} is dropped by the
+# datapath — it never reaches a backend and never reaches a network policy. This is what makes
+# "LAN clients only" a real, tested restriction rather than a comment: VERIFIED by narrowing the
+# range to a /24 that excludes the test client, after which the same query that had been answering
+# stopped being answered at all, and restoring it, after which it answered again.
+#
+# It is also the layer that survives the SNAT above. A CiliumNetworkPolicy cannot express this
+# restriction once the source has been rewritten: measured on this cluster, the forwarded query
+# arrives from the ingress node's internal router address and Cilium resolves that source to the
+# reserved `world` identity, which a `fromCIDR` clause does not match even when the CIDR covers the
+# address (tried: fromCIDR ${CLUSTER_POD_CIDR}, still dropped as `world`). So the peer restriction
+# lives here, where it is actually enforceable, and the policy below restricts the PORTS.

+# =================================================================================================
+# The pihole namespace is default-deny on ingress (the baseline NetworkPolicy in the rendered
+# apps/wave-0/pihole.yaml: `ingress: []`). Cilium enforces the UNION of that NetworkPolicy and the
+# CiliumNetworkPolicies in the namespace, so this file ADDS one path and nothing else. Everything
+# undeclared stays denied, and the existing `pihole-allow-gateway-ingress` (Gateway -> :4180, the
+# oauth2-proxy gate in front of the admin UI) is untouched. PiHole's own :80 is NOT in this rule:
+# the admin UI stays reachable only through the Gateway and oauth2-proxy, and a LAN client that
+# talks to ${PIHOLE_DNS_VIP} on any port other than 53 gets nothing — there is no Service port for
+# it and no policy for it.
+#
+# PORTS ARE THE NARROWING HERE; THE LAN RESTRICTION IS THE SOURCE-RANGE FILTER ABOVE. The peer is
+# `world` for a mechanical reason, not a lazy one: with externalTrafficPolicy Cluster in Cilium's
+# SNAT mode a forwarded query arrives from the ingress node's internal router address, which Cilium
+# resolves to the reserved `world` identity — a `fromCIDR` clause does not match it, which was
+# measured (a fromCIDR of ${CLUSTER_POD_CIDR}, which contains that address, still produced
+# "Policy denied ... identity world" drops in `cilium-dbg monitor`). So `world` is the only peer
+# selector that can describe LAN traffic that has been through the LoadBalancer, and the set of
+# addresses that can actually BE that traffic is fixed by loadBalancerSourceRanges before this
+# policy is consulted. Together: ${LAN_CIDR} in the datapath, udp/53 + tcp/53 here.
+#
+# This is NOT wider than the precedent it follows. unifi-allow-l4-ingress and crafty-allow-ingress
+# admit `fromEntities: [world, cluster, host]` on their L4 ports with NO source-range filter at all;
+# this rule admits fewer entities (no `cluster` — in-cluster pods resolve through CoreDNS and none
+# needs PiHole on :53) on fewer ports, behind a filter those two do not have.
+#
+# WHAT REMAINS REACHABLE WITHOUT THE VIP, ACKNOWLEDGED: Cilium applies source ranges to the
+# LoadBalancer address, not to the NodePorts the same Services allocate, so a host that can route to
+# a node IP can still reach udp/53 and tcp/53 through the NodePort. On this LAN that is the same
+# population the source range admits, and nothing at the edge forwards 53 inward, so PiHole is not
+# an internet-facing open resolver. Say so out loud rather than implying the filter is total.
+#
+# `host` and `remote-node` are named explicitly because node-sourced traffic carries a reserved
+# Cilium identity that no CIDR or `world` selector matches: the kubelet's probes and the
+# node-to-node forwarding that IS the Cluster-policy datapath both need them.

+# Plex plex.tv server-claim token (WS-APPS). SOPS-encrypted (age).
+# Consumed by catalog/plex.yaml as env PLEX_CLAIM via valueFrom.secretKeyRef.
+#
+# NOTE ON THESE COMMENTS: they carry NO dollar-brace expressions, deliberately. This file is applied
+# by the apps-wave-0 Flux Kustomization, which runs envsubst over the built output, and kustomize
+# preserves body comments into that stream (see conformance/tests/l0-static/flux-postbuild-
+# substitution). A braced token quoted from the upstream shell script would be a live hazard here,
+# not prose, so the upstream conditions below are described in words.
+#
+# THE VALUE SHIPPED WITH THIS FILE IS A PLACEHOLDER, DELIBERATELY — the literal string
+# `replace-me-with-a-fresh-plex-tv-claim-token`, not a credential. A https://plex.tv/claim token has
+# a ~4-minute TTL, far shorter than commit -> push -> Flux reconcile -> pod-roll, so no token
+# committed here is ever still valid when the pod starts. This file exists to make the Secret — and
+# therefore the env reference — ALWAYS RESOLVABLE IN THE FLUX GRAPH, not to carry a working token.
+# The real token is injected by the operator inside that 4-minute window: runbooks/plex-claim.md.
+#
+# WHY SHIPPING A PLACEHOLDER IS SAFE (verified against plexinc/pms-docker branch `master`, the
+# s6-overlay v2 script root/etc/cont-init.d/40-plex-first-run, cross-checked byte-identical against
+# the same file extracted from the running `plexinc/pms-docker:latest` image):
+#   - line 106 guards the claim exchange on TWO conditions: PLEX_CLAIM non-empty AND the
+#     PlexOnlineToken pref read out of /config empty. Once the server is claimed that block is
+#     skipped entirely, so whatever this Secret holds is a NO-OP on every later start. Upstream
+#     README: "If server is already logged in, this parameter is ignored."
+#   - on a still-UNCLAIMED /config, an invalid or expired token makes plex.tv answer 403 with an
+#     empty body. curl's exit status is never checked, the sed for the authentication-token element
+#     yields the empty string, and the success branch at line 120 simply does not fire. There is no
+#     else branch and no non-zero exit; the script has no `set -e` and ends by touching
+#     /.firstRunComplete and echoing, so it exits 0. The server comes up UNCLAIMED and serving.
+#     It does NOT crashloop.
+#   - the image never sets S6_BEHAVIOUR_IF_STAGE2_FAILS, whose default is 0 ("continue silently even
+#     if a cont-init script failed"), so even a hypothetical non-zero exit would not halt startup.
+# A MISSING Secret would NOT be safe: the ServiceDefinition schema's valueFrom.secretKeyRef shape
+# has no `optional` field, so an absent Secret is a hard CreateContainerConfigError. That is exactly
+# why this file is committed and listed in apps/wave-0/kustomization.yaml instead of being created
+# by hand at claim time.
+#
+# INJECTION / ROTATION (operator, not agents) — runbooks/plex-claim.md has the timed procedure:

+# qBittorrent DURABLE WebUI credential (WS-APPS). SOPS-encrypted (age), decrypted in-cluster by Flux.
+#
+# WHY THIS FILE EXISTS (defect, measured on prod 2026-09-13):
+#   qBittorrent.conf on the config PVC carried NEITHER `WebUI\Username` NOR
+#   `WebUI\Password_PBKDF2`. qBittorrent 5.x treats that as "no credential set" and generates a NEW
+#   random `admin` password on EVERY process start, announcing it ONLY on stdout ("A temporary
+#   password is provided for this session: ..."). Consequences, both real: (a) Sonarr's and Radarr's
+#   saved download-client credentials stop working at the next qbittorrent pod restart, silently
+#   breaking Completed Download Handling; (b) a human operator has no stable login at all and must
+#   read the pod log after every restart.
+#
+# HOW IT IS APPLIED: catalog/qbittorrent.yaml's app container reads BOTH keys below as env
+#   (QBT_WEBUI_USERNAME / QBT_WEBUI_PASSWORD) and its `lifecycle.postStart` hook — the same idiom as
+#   gitea's break-glass admin bootstrap — DERIVES the PBKDF2-HMAC-SHA512 digest qBittorrent stores
+#   and asserts both keys into /config/qBittorrent/qBittorrent.conf on EVERY container start, then
+#   verifies the WebUI actually accepts them. Level-triggered: a pod restart, a config-PVC restore
+#   from an older backup, and a rebuild-from-git onto an EMPTY PVC all end with this SAME
+#   credential, because the hook re-asserts it on every start rather than once.
+#
+# webui-username: the WebUI account name. qBittorrent has exactly ONE local account, and `admin` is
+#   the name its own temporary-password path uses, so keeping it avoids inventing a second identity.
+# webui-password: the durable plaintext. It is ALSO what Sonarr's and Radarr's download-client
+#   entries store in their own databases (app state on their config PVCs, NOT in git — see
+#   DECISIONS-LOG), so rotating it here means re-pointing both arrs.
+#   Deliberately alphanumeric: it travels through a urlencoded WebAPI login body and two arr JSON
+#   payloads, and a shell/URL-special character in any of those is a bug waiting to happen.

+# Manifests under test: every PrometheusRule in apps/wave-0/ — gitea, jackett, pihole, plex,
+# qbittorrent (container/Deployment) and vm-demo (KubeVirt VMI). The harness discovers this file by
+# the SUITE convention (`<dir>/tests/*.test.yaml`) and flattens those RENDERED manifests, so these
+# tests run against the exact expressions Flux applies, never a copy.
+#
+# Run with: platform/monitoring/tests/run.sh apps/wave-0/tests/app-slis.test.yaml
+#           (the merge gate runs the same harness via
+#            conformance/tests/l0-static/alert-rules-unit-tested)
+#
+# WHY THESE EXIST. Until 2026-09-13 every one of these rules read `up{job="<app>"} == 0` while the
+# rendered ServiceMonitor named a Service port (`metrics`) that no rendered Service defined. The
+# monitor discovered ZERO targets, so no `up{job="<app>"}` series existed and the rule could not
+# fire — on prod, `count by (job) (up)` listed 24 jobs and not one of the twelve appeared.
+# `PrometheusTargetsMissing` could not see it either: a target that was never discovered has no `up`
+# series to be 0. The rules now read kube-state-metrics / kubevirt series that DO exist for these
+# workloads (verified on prod), and every rule below is pinned in BOTH directions:
+#   * QUIET on the healthy state -> it is not permanently firing;
+#   * FIRING when the workload has no ready replica -> it is not inert;
+#   * FIRING when the signal is ABSENT -> the failure mode that produced this whole defect class
+#     (a rule that goes quiet because its series vanished) is itself alerted on.
+#
+# CLOCK/`for` CONVENTION: sample interval 1m, series 21 samples long, evaluated at 10m — comfortably
+# past every rule's `for: 5m` and well inside Prometheus' 5m lookback.

+# Run with: platform/monitoring/tests/run.sh apps/wave-1/tests/app-slis.test.yaml

+# structurally inert on prod. Each is now pinned QUIET on the healthy state, FIRING on no-ready-
+# replica, and FIRING when the signal is ABSENT.
+#
+# KEYCLOAK IS THE INTERESTING ONE. Its server is a StatefulSet run by the Keycloak operator, NOT the
+# Deployment this ServiceDefinition would otherwise imply — so its rule reads
+# kube_statefulset_status_replicas_ready (catalog/keycloak.yaml declares

+# (platform/keycloak/client-secret-reconciler.yaml, the CNPG grant reconciler in
+# apps/wave-0/nextcloud-db.yaml) exist because their state has NO declarative entry point — a
+# Keycloak client secret lives in Keycloak's own database and a Postgres GRANT lives in the
+# catalog, and nothing in a manifest can express either. PiHole v6 is not that case. Every FTL
+# setting has an `FTLCONF_<section>_<key>` environment variable, and a value supplied that way is
+# ENV-FORCED: FTL logs it as "forced through environment", applies it on every start ahead of
+# /etc/pihole/pihole.toml, and marks it read-only in the admin UI so a human cannot drift it. That
+# is strictly better than a reconciler — it is enforced at t=0 on a cold start rather than at the
+# next cron tick, it cannot be defeated by the UI, and it carries no extra RBAC, image or Job. A
+# CronJob here would be ceremony around a knob the app already exposes. (Verified on the live prod
+# image, PiHole Core v6.4.3 / FTL v6.7, 2026-09-14.)

+# upstream servers: the live pod's pihole.toml carried a hand-set `upstreams` marked "### CHANGED"
+# that no manifest declared, so a restart would have left PiHole with upstreams = [] and no

+  # LEVEL-TRIGGERED CREDENTIAL ASSERTION, run on EVERY container start.

+  # WHY A postStart HOOK AND NOT A CronJob RECONCILER: the repo's idiom for "state Flux cannot reach
+  # directly" is the level-triggered CronJob (platform/keycloak/client-secret-reconciler.yaml,
+  # apps/wave-0/nextcloud-db.yaml). That idiom's PRINCIPLE — desired state lives in git and is
+  # RE-ASSERTED unconditionally, never set once — is exactly what is applied here, but the trigger is
+  # the container start rather than a clock, because the failure this closes IS a container start:
+  #   * The credential is read by qbittorrent-nox ONCE, at process start, from a file on the config
+  #     PVC. A 15-minute cron would therefore leave a 0-15 minute window after every restart, PVC
+  #     restore or rebuild in which the app serves a random password and both arrs are broken. The
+  #     hook has no such window: it runs before/with the very start that would otherwise regenerate.
+  #   * A CronJob would also have to reach the conf from OUTSIDE the pod — mounting an RWO Longhorn
+  #     PVC that the app already holds, or `kubectl exec`-ing with RBAC it would need granting — and
+  #     then edit a file UNDER the running process, whose own save-on-exit can overwrite the edit.
+  #     In-container, before the service starts, none of that exists.
+  #   * It needs no ServiceAccount, no RBAC, no NetworkPolicy and no API token: strictly less
+  #     privilege than the CronJob alternative (R-SEC/least-privilege).
+  # The gitea entry's postStart is the same pattern (idempotent bootstrap of a credential the app
+  # keeps in its own state), and the schema documents this hook for exactly that use.
+  #
+  # AND WHY NOT AN initContainer, which is the genuinely tempting third option: it would run strictly
+  # BEFORE qbittorrent-nox, removing the race the `s6-svc -r` below exists to cover, and its stdout
+  # would reach `kubectl logs -c <init>` instead of the kubelet. Two reasons it loses here:
+  #   * It CANNOT do step (3) — the ground-truth login that proves the WebUI actually accepts the
+  #     credential — because the WebUI is not running yet. That assertion is the most valuable line
+  #     in this whole mechanism: it is what turns "we wrote a file" into "the credential works", and
+  #     writing the right PBKDF2 bytes is precisely the part that is easy to get subtly wrong.
+  #   * The ServiceDefinition schema (1.5.0) has `lifecycle` but NO initContainers field, so it would
+  #     mean a schema version bump plus a renderer change — a blast radius across every service's
+  #     golden — to buy something strictly weaker than what the hook already does.
+  # The honest summary: postStart trades a short, self-healing start-up race (detected and closed by
+  # the s6 restart + re-verify loop) for the ability to VERIFY. That is the right trade.
+  #
+  # DURABILITY, the whole point — all three paths end with the SAME credential:
+  #   pod restart      -> conf on the PVC already holds it; the hook verifies and writes NOTHING.
+  #   config-PVC restore from an older backup -> restore requires the pod to be recreated, so the
+  #                       hook runs and re-asserts over whatever the snapshot contained.
+  #   rebuild from git -> empty PVC; the image copies /defaults/qBittorrent.conf, the hook writes the
+  #                       credential into it before the service is serving. Nothing outside git.
+  #
+  # WHAT IT DOES NOT DO: it never weakens authentication. `WebUI\AuthSubnetWhitelist` (bypassing auth
+  # for the pod CIDR) was REJECTED: it leaves the human login broken, and makes qBittorrent's auth
+  # depend on network policy staying correct forever. The WebUI keeps demanding a password; that

+  # /downloads, which is precisely where this app is ALREADY configured to write.
+  #
+  # WHY subPath: downloads AND NOT THE EXPORT ROOT AT /media (the shape sonarr/radarr use):
+  #   * LEAST PRIVILEGE, AND IT COSTS NOTHING HERE. A download client has no business writing the
+  #     LIBRARY. The arrs need the root mount because THEY hardlink downloads/ -> tv/ or movies/ and
+  #     link() is a same-MOUNT operation (EXDEV otherwise) — their smallest common ancestor genuinely
+  #     IS the export root. qBittorrent performs no such cross-directory link: it writes into the
+  #     downloads tree and nothing else, so narrowing to that subtree removes movies/, tv/ and photos/
+  #     from this pod's mount namespace without removing any operation it actually performs.
+  #   * HARDLINKS STILL WORK, because they are not done here. The arrs still see ONE mount containing
+  #     both /media/downloads and /media/tv, so their link() stays intra-mount. Proven live 2026-09-12:
+  #     a file created from this pod under /downloads was hardlinked from the sonarr pod between
+  #     /media/downloads/... and /media/tv/... with st_nlink 1 -> 2 and no EXDEV.
+  #   * IT IS ONE MOUNT, so the L0 test `bulk-tier-distinct-from-replicated` assertion (6) — no
+  #     workload mounts one export twice — holds. That assertion is about TWO mounts inside ONE pod;
+  #     a single subPath mount is not the EXDEV trap, two are.
+  #   * The narrowing is a CLIENT/kubelet guarantee, stated honestly: the NFS server still exports the
+  #     whole dataset to this node, so the containment is the mount namespace, not the server's ACLs —
+  #     the same class of caveat docs/BULK-NFS-STORAGE.md §5 records for plex's readOnly.
+  #
+  # NOT readOnly — this is the one workload whose whole job is WRITING here.
+  #
+  # KNOWN, DELIBERATE SIDE EFFECT ON SHARED STATE: the image's init-qbittorrent-config runs
+  # `lsiown abc:abc /downloads` (non-recursive) whenever /downloads is a mount, so starting this pod
+  # chgrps /mnt/Storage/plex/downloads from 1000:1000 to 1000:3000 on the SERVER. Benign and verified:
+  # the directory is mode 0755, whose group bits (r-x) are identical to its other bits, so no consumer
+  # — k3s or legacy — gains or loses any access. Recorded because it is a write to state shared with
+  # non-cluster consumers, which should never be a surprise.
+  #
+  # PATH AGREEMENT WITH THE ARRS IS STILL *NOT* CLOSED — see DECISIONS-LOG 2026-09-12 "Remote Path
+  # Mappings". This pod calls the finished file /downloads/<name>; sonarr/radarr call the same bytes
+  # /media/downloads/<name>. Same inode, different absolute path, so Completed Download Handling needs
+  # ONE Remote Path Mapping per arr (remote host `qbittorrent.qbittorrent.svc.cluster.local`, remote
+  # path /downloads/, local path /media/downloads/).
+  #
+  # THOSE MAPPINGS ARE NOW CONFIGURED AND VERIFIED ON PROD (2026-09-12), together with the qBittorrent
+  # download client itself — which did not exist in EITHER arr until then (both
+  # `GET /api/v3/downloadclient` returned `[]`, so completed-download handling had never been wired up
+  # at all). `downloadclient/testall` reports isValid=true in both, and Sonarr's queue was observed
+  # reporting outputPath=/downloads/... with the mapping deleted and /media/downloads/... with it
+  # present — same torrent, same client.
+  #
+  # BUT THEY LIVE IN THE ARRS' OWN DATABASES (app state on their config PVCs), NOT IN GIT: a rebuild
+  # from git alone does NOT restore them and no gate here notices their absence. The alternative —
+  # repointing qBittorrent's SavePath at /media/downloads and mounting this subPath there instead —
+  # buys path agreement at the cost of editing THIS app's config PVC, which is also app state; it was
+  # not chosen because it changes a running download client's save path, which the deferral above
+  # already shows is easy to get wrong. It is nonetheless the RECOMMENDED end state (it makes the
+  # mappings unnecessary and puts the mountPath half of the fix in git) and is awaiting an operator
+  # decision, not a technical blocker.
+  #
+  # RELATED OPEN BLOCKER: this app has no durable WebUI credential (no WebUI\Username /
+  # WebUI\Password_PBKDF2 in qBittorrent.conf), so v5 issues a NEW temporary `admin` password on every
+  # start. The arrs' saved download-client password therefore goes stale on every pod restart. See the

+
+    `internal` renders NO public DNS record. That sentence was in the contract from the start and
+    nothing enforced it: ExternalDNS watched EVERY HTTPRoute the shared Gateway carried, so an
+    `internal` service's route published `<name>.${BASE_DOMAIN}` into the PUBLIC authoritative
+    Cloudflare zone, answering with the Gateway VIP — an RFC1918 address. Six of them did
+    (jackett, pihole, qbittorrent, radarr, semaphore, sonarr), which published the internal
+    subnet, the Gateway VIP and a full service inventory to anyone who asked, and made every one
+    of those names a DNS-rebind primitive that the SOHO router strips on the way back in.
+
+    THE MECHANISM, verified against the DEPLOYED version (chart >=1.21.0 <1.22.0, app v0.21.0 —
+    `registry.k8s.io/external-dns/external-dns:v0.21.0`, read off the live prod Deployment), not
+    from memory. external-dns v0.21.0 `source/annotations/processors.go`:
+
+        func IsControllerMismatch(entity metav1.ObjectMetaAccessor, rType string) bool {
+            value, ok := entity.GetObjectMeta().GetAnnotations()[ControllerKey]
+            if ok && value != ControllerValue { ...; return true }
+            return false
+        }
+
+    with `ControllerKey = "external-dns.alpha.kubernetes.io/controller"` and
+    `ControllerValue = "dns-controller"`. `source/gateway.go` calls it per route inside
+    `Endpoints()`, BEFORE any hostname is resolved:
+
+        if annotations.IsControllerMismatch(meta, src.rtKind) { continue }
+
+    so an HTTPRoute carrying any other value is not merely unpublished — it never becomes an
+    endpoint at all, for any hostname it names. `source/service.go` applies the identical check,
+    so the same annotation scopes the `service` source too if a rendered Service ever grows an
+    external-dns hostname.
+
+    WHY THIS IS STRUCTURAL AND NOT INCIDENTAL. The annotation is derived HERE, from `exposure`,
+    with no per-service list anywhere: every HTTPRoute this renderer emits for an `internal`
+    service carries it, and ci/render-golden.sh proves `apps/` reproduces byte-for-byte from
+    `catalog/`, so an `internal` service cannot EXIST in the applied tree without it. Flipping
+    `exposure: internal` to `public` is the only edit that can publish a name, which is exactly
+    the operator-facing declaration R-DNS-03 is written in terms of. The L0 check
+    conformance/tests/l0-static/internal-services-publish-no-public-dns re-proves all of that on
+    every gate run, including that this function reads `exposure` rather than naming services.
+
+    WHY NOT A CLUSTER-WIDE OPT-IN FILTER (`--label-filter`, chart `labelFilter`). It exists, and
+    v0.21.0's own `--help` names both sources in use as supporting it ("currently supported by
+    source types crd, gateway-httproute, ... service and ambassador-host"), so a "publish only
+    what is labelled" posture is available and is STRONGER by default. It is not taken here
+    because its blast radius is not this defect's: seven published names come from hand-authored
+    platform/apps manifests that carry no `exposure` field and that this renderer never sees
+    (auth/oauth2-proxy, crafty + crafty-mc, grafana, headlamp, the homepage apex, unifi). An
+    opt-in filter DELETES all seven the moment it is set, and whether each should stay published
+    is an operator decision, not a renderer one. Per-resource exclusion has exactly the blast
+    radius of the reported defect. The filter remains the available hardening once those seven
+    are adjudicated — see platform/externaldns/helmrelease.yaml.

+    Worse than a wrong threshold: an inert rule and a correct rule are indistinguishable on a
+    healthy cluster, and the generic safety net cannot see the difference either — a target that
+    was never discovered has no `up` series for PrometheusTargetsMissing to find at 0.
+
+    Rewriting the SLI against the app's own /metrics was NOT an option for most of this catalog:
+    Plex, Pi-hole, Jackett, qBittorrent, Sonarr, Radarr, Seerr, Semaphore and Nextcloud export no
+    Prometheus metrics without a separate exporter sidecar per app. So the `up` SLI is expressed
+    against kube-state-metrics, which IS scraped and DOES carry a series for every workload — the
+    same idiom KeycloakDown in platform/monitoring/alerts.yaml has used since it was fixed.
+
+    The `or absent(...)` half is deliberate and load-bearing: it makes the DISAPPEARANCE of the
+    signal fire the alert instead of silencing it. A rule that can only fire on `== 0` is a rule
+    that goes quiet when the workload object (or kube-state-metrics) vanishes, which is precisely
+    how the old expression failed. It is also why this rule cannot be permanently firing where the
+    workload exists: the series is present and non-zero on a healthy cluster (verified on prod).

+(`kyverno test`), and **`conformance/run.sh --layer l0 --include-scope whole-repo`** — the whole-repo
+L0 invariants a per-resource policy cannot express (secret hygiene across every tracked file,
+least-privilege RBAC, spec-immutability enforcement). See `conformance/tests/README.md`.
+
+### `--include-scope whole-repo`: why the L0 sub-stage is not purely requirement-scoped
+
+R-TEST-03 runs the conformance subset a change **touches**. That has one blind spot, and it is the
+worst-shaped kind: an invariant that quantifies over the whole tracked tree, or over subtrees the
+coarse path→requirement map keys to *nothing* (`apps/`, `infra/`, most of `platform/`), cannot be
+selected *by* the requirements a change touches — because **the change most likely to break it
+attributes no requirement at all**. Requirement-scoped selection then filters the check out of
+exactly that change.
+
+This used to be handled by a hand-written "UNCONDITIONAL" stage per such check (3c subst-safety,
+3d keycloak-client-secrets, 3e bulk-tier): three near-identical rationales, three hardcoded
+`check.sh` paths, three copies of the same `rc 0/3/*` case block — and, worse, a mechanism that
+failed **silently**, because whoever added the next whole-repo invariant had to *remember* to write
+a stage. Those stages are gone. A test now **declares** `conformance.home.k3s/scope: "whole-repo"`
+and the runner unions every declaring test into the run. Adding the annotation is the only step.
+
+`rc 3` is preserved exactly as those stages had it: a **SKIP** of a scope-declared check means the
+tree it audits has vanished, so the runner exits `3`, `ci/l0.sh` sets the gate's own `rc=3`, and the
+gate reports SKIPPED — **never a pass**. The mechanism is itself proven, end-to-end and falsifiably,
+by `conformance/tests/l0-static/whole-repo-invariants-wired`; `conformance/lib/common.sh` carries the
+full rationale and the incidents behind it.

 ## Exit-code contract

@@ -37,6 +59,47 @@ Every stage script uses: **`0` = pass · `1` = fail (blocks merge) · `3` = SKIP
 with no cluster, or an unwired seam / missing tool). A `3` is **never** counted as green — that is how
 the gate stays honest in Phase 0 (no fake green).

+### The gate's OWN verdict (changed 2026-09-13 — read this if you consume the exit code)
+
+**`MERGE GATE: PASS` + exit 0 means every stage that was supposed to run RAN and was GREEN.** It
+used to mean less than that: a FAILED stage set the block flag but a SKIPPED one only printed a
+warning, so the gate printed `l0: skipped (unwired seam / missing tool) — not green` and then
+`MERGE GATE: PASS`, exit 0. That happened for real twice — a missing `promtool` (the alert-rule
+unit tests) and a missing pinned `kyverno` CLI — and exit 0 is what automation reads as
+merge-approved. Fail-open in the one component whose whole job is to fail closed.
+
+| verdict | exit | meaning |
+|---|---|---|
+| `MERGE GATE: PASS` | `0` | every stage that was supposed to run ran and was green; the R-TEST-03 subset was checked. Any capability the environment **declared** out of scope is **named in the headline** (see below), so a PASS never implies more than it verified. |
+| `MERGE GATE: BLOCKED` | `1` | a stage FAILED, or a stage did not run **where it must**, or the decision input is unusable. |
+| `MERGE GATE: UNDETERMINED` | `3` | nothing failed, but a stage did not run, so greenness was **not established**. Never a pass; non-zero so nothing can read it as approval. `3` is this repo's existing "not run" code, now spoken by the gate as a whole and not only by its stages. |
+| `MERGE GATE: NOT APPLICABLE` | `0` | there is no branch under gate at all (`HEAD` is on base — a push-to-`main` run). Stages ran; no subset was checked, and the headline says so. |
+
+Precedence: BLOCKED > UNDETERMINED > NOT APPLICABLE > PASS.
+
+**`make` masks the difference.** GNU make reports any recipe failure as its own exit `2`, so
+`make -C ci gate` collapses `1` and `3` into `2` (the headline still tells a human which it was). A
+caller that must distinguish them invokes `./ci/gate.sh` directly.
+
+### Which skips block, and why — a skip is not one thing
+
+| stage | a skip there means | verdict |
+|---|---|---|
+| `lint`, `l0`, `render-golden`, `l1` | a **pinned tool is absent** or a **wired seam went unwired** — it *could not run* | **BLOCKED** under strict skips (a CI runner: the toolchain is installed for us by `.gitea/workflows/scripts/install-tools.sh`, so a skip is a defect); **UNDETERMINED** otherwise (a workstation missing a tool is a real local condition — still non-zero, still not a pass; the remedy is `infra/devcontainer/dev.sh`, which carries the pinned toolchain) |
+| `spec-immutability` (R-TEST-06) | the sibling spec repo is not checked out, so the spec **could not be verified** | **UNDETERMINED** — unverified is unverified. Deliberately *not* upgraded to BLOCKED by strict skips: the live runner does not check the spec repo out at all, so blocking would leave the only enforced status check permanently red for a reason no PR could clear. It is therefore the **one** skip whose non-answer a caller may knowingly tolerate, and `.gitea/workflows/gate.yml` does so in one visible line. `REQUIRE_SPEC_VERIFICATION=true` makes it a hard block once that checkout is wired. Locally: check the spec repo out beside this one, or set `SPEC_REPO` (`dev.sh` mounts a sibling automatically). |
+| `conformance` (L2/L3) | `CLUSTER_AVAILABLE!=true` — the environment **declared** the capability absent (documented Phase-0 behaviour) | **does not deny a PASS**: a declared-inapplicable stage was never *supposed* to run. It is NAMED in the PASS headline and step summary, the touched requirements it would have covered are reported UNVERIFIED, and `REQUIRE_CLUSTER_TESTS=true` (Phase 1+) turns that into a block. A skip **despite** `CLUSTER_AVAILABLE=true` is a defect and BLOCKS. |
+
+That asymmetry is the whole rule: **declared-not-applicable may pass; could-not-run may not.**
+
+`GATE_STRICT_SKIPS=true|false` decides strictness and is **declared, never sniffed** — `gate.yml`
+sets it on the gate step, because the workflow is the thing that knows it is CI. Unset, it falls
+back to `GITHUB_ACTIONS` / `CI` (set by the runner itself). A wrong answer in either direction
+cannot fail open: both branches are non-zero and neither is a PASS. Set it locally to rehearse CI
+strictness.
+
+Locked down by `ci/tests/gate-decision.test.sh` (47 assertions over the decision table: stubbed
+stage outcomes against the real `gate.sh`; 32 of them fail against the pre-2026-09-13 gate).

+#   CI       the pinned toolchain is installed by .gitea/workflows/scripts/install-tools.sh
+#            before the gate runs, and every seam is on `main`. A stage that skips here is a
+#            DEFECT (a tool dropped from the installer, a seam that went unwired) -> BLOCK.
+#   local    a missing pinned tool is a real, ordinary local condition -> the gate reports
+#            UNDETERMINED (exit 3): not green, not a pass, but distinguishable from a red.
+#
+# HOW STRICTNESS IS DECIDED — DECLARED first, detected only as a fallback:
+#
+#   1. GATE_STRICT_SKIPS=true|false is the AUTHORITY. .gitea/workflows/gate.yml sets `true` on
+#      the gate step, so on the one CI runner that matters strictness is a DECLARATION IN THE
+#      WORKFLOW, not an inference: the environment that KNOWS it is CI says so, and no
+#      env-var sniffing can get it wrong.
+#   2. `auto` (the default — anywhere the caller said nothing) falls back to GITHUB_ACTIONS /
+#      CI, which are set by the runner ITSELF (Gitea's act_runner, as well as GitHub). We do
+#      NOT sniff hostnames, paths or tool availability: a heuristic that guesses "this looks
+#      like CI" is exactly the unreliable inference this gate must not contain.
+#
+# WHY A WRONG ANSWER CANNOT FAIL OPEN: both branches are non-zero and NEITHER is a pass. A CI
+# run misread as local yields UNDETERMINED (exit 3) instead of BLOCKED (exit 1) — that still
+# fails the job unless its caller explicitly tolerates 3, which gate.yml does only knowingly
+# and only for the one declared-environmental skip (see its comment). A workstation misread as

+# ci/render-keycloak-client-urls.py
+#
+# Render platform/keycloak/client-urls.yaml FROM platform/keycloak/keycloak-realm-import.yaml.
+#
+# WHY THIS EXISTS
+# ---------------
+# The Keycloak realm import is a ONE-SHOT that fails OPEN: once it rests at
+# Done=True / Started=False it never re-runs, so a redirect URI changed in git is
+# never applied to the realm. The client-secret half of that failure class is
+# already healed by a level-triggered CronJob (platform/keycloak/client-secret-
+# reconciler.yaml). This renderer supplies the DESIRED STATE that the same CronJob
+# needs to heal the URL half.
+#
+# THE CONSTRAINT THAT SHAPES IT: the reconciler pod runs with
+# automountServiceAccountToken: false. It has NO Kubernetes API access at all, by
+# design (R-SEC-02) — so it cannot read the KeycloakRealmImport CR to learn what
+# the realm is supposed to look like. Its inputs must be MOUNTED. Hence a
+# ConfigMap.
+#
+# A hand-authored ConfigMap would be a SECOND SOURCE OF TRUTH for every public
+# hostname in the realm, free to disagree with the realm import — and "two
+# declarations that can disagree" is the same shape as the bug this whole effort
+# is closing. So the ConfigMap is GENERATED from the realm import and the
+# generation is GATED: conformance/tests/l0-static/keycloak-client-secret-
+# reconciler/check.sh runs this script with --check on every merge, and the merge
+# fails if the committed file is not what this renderer produces. That is the same
+# render==golden idiom catalog/render.py + ci/render-golden.sh already use for
+# apps/.
+#
+# STRINGS ARE COPIED VERBATIM, NEVER RE-DERIVED. If a URL in the realm import is
+# written as a Flux substitution token (https://grafana.${BASE_DOMAIN}/...), the
+# token is carried through into the ConfigMap CHARACTER FOR CHARACTER. Both files
+# are rendered by the SAME Flux Kustomization (./platform-config, whose
+# postBuild.substituteFrom reads cluster-vars), so both are substituted in the
+# same pass with the same values and cannot disagree about what BASE_DOMAIN is.
+# This renderer never parses, splits, or reconstructs a hostname, and never reads
+# cluster-vars — so there is no second place for the domain to be decided.

+# guard by content rather than by path, so it activates on exactly that change. Removing
+# the entry would let the change introducing a guard be gated by nothing, which is the

+# FAILS OPEN: an undefined `${X}` becomes the empty string while the Kustomization still reports
+# Ready (DECISIONS-LOG 2026-09-01 — that is how `k8sServiceHost` was emptied and Cilium broke on 2

+# in every command example blanked, in a file nobody re-reads after writing. Worse, the L0 check
+# `conformance/tests/l0-static/flux-postbuild-substitution` scans only files reachable through
+# kustomization `resources:`, not `configMapGenerator` inputs, so the damage would be invisible to
+# the gate as well.
+# The fix is to have nothing to substitute. The only knob this tier would have wanted is the apex

+# environment-independent by construction and R-ENV-02 ("authored once, promoted dev -> prod") holds
+# without substitution rather than because of it.
+# IF A FUTURE KNOB EVER GENUINELY NEEDS SUBSTITUTION HERE: do not add substituteFrom to this

+# ConfigMap in an unsubstituted one, or the runbooks lose their shell examples.

+
+DECLARED SCOPE, AND WHY A SKIP IS NOT ALWAYS HARMLESS (--unwired-scope)
+----------------------------------------------------------------------
+Exit 0 here means "every selected check passed"; a check that exits 3 is SKIPPED and, by
+default, does not fail the run (a scaffold with no check script, an audit whose subject
+subtree does not exist yet). That default is WRONG for a WHOLE-REPO invariant. Those are the
+checks ci/l0.sh used to run as hand-written "UNCONDITIONAL" stages, and each of those stages
+mapped rc 3 to the GATE's rc 3 with the words "not a pass":
+
+    3) skip "substitution check SKIPPED (clusters/ absent) — not a pass"
+       summary "- subst-safety: **SKIPPED** (nothing to audit)"
+       if [ "$rc" -eq 0 ]; then rc=3; fi
+
+A whole-repo check reporting "nothing to audit" is reporting that the tree it audits has
+VANISHED — which is a louder problem than the check failing, not a quieter one. So:
+
+  --unwired-scope SCOPE   a test DECLARING `<prefix>/scope: SCOPE` whose check SKIPS (rc 3,
+                          or no check script at all) makes this runner exit 3 instead of 0.
+                          Hard failures still win (exit 1); rc 3 never masks one.
+
+Exit codes: 0 all selected checks passed / 1 at least one FAILED / 3 nothing failed but a
+scope-declared check was UNWIRED. conformance/run.sh propagates 3 verbatim; ci/l0.sh turns it
+into the gate's own rc 3. This is the ONE place the "unwired, not green" rule lives now,
+instead of once per hand-written stage.

+# =============================================================================
+# L0 STATIC — every metric an alert rule queries is CLAIMED by a scrape target this repo configures
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# THE DEFECT THIS CLOSES. An alert rule whose metric is never scraped is not a broken alert — it is
+# an ABSENT alert that reads as a present one. `longhorn_volume_robustness == 2` over a TSDB with no
+# longhorn_* series returns no vector, so the rule is permanently quiet, permanently "healthy", and
+# indistinguishable from a correct rule on a healthy cluster. It survives review (the PromQL is
+# right), it survives `promtool test rules` (the unit test supplies the series itself), and it
+# survives every dashboard (nobody looks for a panel that was never built).
+#
+# MEASURED ON PROD, 2026-09-13, before this change — 13 rules across three families were inert:
+#   count(longhorn_volume_robustness)                        => (empty)   4 rules
+#   count({__name__=~"certmanager.*"})                       => (empty)   3 rules
+#   count(hubble_drop_total)                                 => (empty)   1 rule
+#   count by (job) (up)                                      => 20 jobs, none Longhorn/cert-manager/Hubble
+# So storage health was unmonitored on a cluster whose prod-1 had just had a failing SSD
+# (DECISIONS-LOG), TLS expiry was unmonitored with the live `wildcard-home` wildcard 89 days from
+# expiry, and the platform had no policy-drop visibility at all. The Flux family (gotk_*, 5 rules)
+# was the same defect and was fixed separately in a79693d.
+#
+# GIVEN every alerting rule in every PrometheusRule in the repo (platform/**, apps/wave-*),
+# WHEN  each rule's PromQL is parsed for the metric names it selects,
+# THEN  (1) every metric name is CLAIMED by exactly one declared scrape owner, and each owner's
+#           claim is PROVEN AGAINST THE REPO — the file that enables that scrape must still contain
+#           the enabling declaration, so deleting `metrics.serviceMonitor.enabled` from
+#           platform/longhorn/helmrelease.yaml fails this check instead of silently re-inerting four
+#           storage alerts;
+#       (2) an owner's NEGATIVE conditions hold too, where the enablement can be defeated without
+#           being deleted — cert-manager's chart calls `fail` if podmonitor and servicemonitor are
+#           both set, Longhorn's own NetworkPolicies drop the scrape unless
+#           networkpolicy-metrics.yaml is wired, and kube_node_labels does not exist at all unless
+#           kube-state-metrics' metricLabelsAllowlist names the label;
+#       (3) a metric with NO owner FAILS, unless it is declared in KNOWN_UNWIRED_METRICS — a
+#           shrink-only register (hubble_drop_total today, with the CNI-rollout reason recorded);
+#       (4) `up{job="X"}` is audited on its own axis, because `up` always exists and so the metric
+#           check above can never see this failure: where the repo authors a Service and a
+#           ServiceMonitor in the SAME file, the monitor's endpoint port must be a port that Service
+#           actually defines. All 12 apps/* `<app>-down` SLI rules used to fail this (the monitors
+#           named port `metrics`; no app Service defined one) and were registered in
+#           KNOWN_UNWIRED_JOBS with the live proof that their `up{job=...}` series did not exist.
+#           THAT REGISTER IS NOW EMPTY BECAUSE THE TWELVE RULES WERE FIXED, not waived: they read
+#           kube-state-metrics readiness of their own workload object instead (2026-09-13), the dead
+#           ServiceMonitors are gone, and so is this axis' only subject. The monitor side therefore
+#           moved into its own check — tests/l0-static/servicemonitor-ports-resolve — which needs no
+#           alert rule to reach a monitor, resolves by selector across the whole tree instead of by
+#           same-file adjacency, and proves its resolver on fixtures so it cannot pass merely for
+#           lack of subjects;
+#   AND (5) the check is LOAD-BEARING: this Test DECLARES `conformance.home.k3s/scope: whole-repo`,
+#           so ci/l0.sh Stage 3b's `--include-scope whole-repo` unions it into EVERY gate
+#           invocation, and ci/gate.sh blocks the merge when the l0 stage fails.

+# WHY BOTH REGISTERS ARE RATCHETS AND NOT BLANKET FAILURES: the same reasoning as
+# alert-rules-unit-tested. Failing outright on the 12 app SLI rules would have made the gate red
+# until exporters existed for Plex, Pi-hole, Jackett, qBittorrent, Sonarr, Radarr, Seerr and friends
+# — none of which speak Prometheus natively — so the gate would have been disabled, and a disabled
+# gate protects nothing. Merely printing the gap is how these 13 rules stayed inert for three phases.
+# (The ratchet did its job: the twelve were closed a day later without an exporter, by reading a
+# signal that already existed. The register is empty now, and that is the outcome it was for.)
+# So each gap is DECLARED, counted on every run, and CANNOT GROW: a new alert on an unclaimed
+# metric FAILS, a new Service+ServiceMonitor pair with a mismatched port FAILS, and a STALE
+# register entry (the gap was closed, or the alert deleted) FAILS too, so neither register can rot
+# into fiction.
+#
+# STATUS: EXECUTABLE. `check.sh` is an offline assertion script (PyYAML, the same dependency as
+# catalog/render.py and dev-nodes-provisioned-as-code); conformance/run.sh --layer l0 and ci/l0.sh
+# run it directly, and this Chainsaw Test wraps the SAME script.
+#
+# NOT proven (all named in check.sh's header, which carries the full list). The one worth stating
+# here because it bit this very repo: an owner claims metrics by PREFIX, so this proves the SCRAPE
+# TARGET exists, never that the exporter emits that exact SERIES NAME.
+# `kubevirt_vmi_phase_count{phase="Failed"}` sat inside the scraped kubevirt_ family on an UP target
+# and did not exist at all on the deployed KubeVirt (corrected here to
+# `kubevirt_vmi_info{phase="failed"}`, lowercase — a capital-F matcher is equally inert). Catching
+# that needs the exporter's own metric list, i.e. a live read; it belongs to a future L1/L3 check
+# that diffs alert metrics against /api/v1/label/__name__/values.
+#
+# Also not proven: that a target is UP. This is static — it asserts the
+# enabling declaration is in git, never that the endpoint answers, that the chart still honours the
+# value key, or that a NetworkPolicy is sufficient. Those were established by live prod reads
+# recorded in the commit message (longhorn_volume_robustness 44 series, certmanager_* 104 series,
+# all six new targets up==1). It also cannot check a monitor whose Service comes from a Helm chart
+# rather than from this repo — the port name lives outside the tree — which is why (4) is scoped to
+# same-file Service+ServiceMonitor pairs. And it does not judge thresholds or reachability-to-human
+# (R-OBS-02 / the L3 alerting test).

+# returns no vector. The rule is therefore permanently quiet, permanently "healthy", and
+# INDISTINGUISHABLE from a correct rule on a healthy cluster. It passes review (the PromQL is
+# right). It passes `promtool test rules` (the unit test supplies the series itself, so a unit
+# test proves nothing about whether anything scrapes them). It shows up on no dashboard, because
+# nobody looks for a panel that was never built.
+#
+# Measured on prod 2026-09-13, BEFORE the change that added this check — 13 rules were inert:

+# Storage health was unmonitored on the cluster whose prod-1 had just had a failing SSD; TLS
+# expiry was unmonitored with the live `wildcard-home` wildcard 89 days out; there was no
+# policy-drop visibility at all. The gotk_* family (5 more rules) was the same defect, fixed
+# separately in a79693d.
+#
+# WHAT MAKES THIS CLASS DIFFERENT from the two failure modes alert-rules-unit-tested catches: a
+# permanently-firing rule is loud, and a rule that behaves wrongly against synthetic series is
+# caught by promtool. This one is caught by NEITHER, because the missing thing is not in the rule
+# file at all — it is a `serviceMonitor.enabled` that was never set in a completely different
+# component's HelmRelease. So the audit has to cross from the alert to the scrape config, which is
+# what the owner table below does.
+#
+# GIVEN every alerting rule in every PrometheusRule in the repo,
+# WHEN  each rule's PromQL is parsed for the metric names it selects,
+# THEN  (1) every metric name is CLAIMED by exactly one declared owner in SCRAPE_OWNERS, and the
+#           owner's `require` regexes still match its file — so deleting the enablement from
+#           platform/longhorn/helmrelease.yaml FAILS here instead of silently re-inerting four
+#           storage alerts;
+#       (2) each owner's `forbid` regexes do NOT match, for the cases where the enablement can be
+#           defeated without being deleted (cert-manager's chart `fail`s if podmonitor and
+#           servicemonitor are both enabled; an `enabled: false` inside the exporter's own block);
+#       (3) a metric with no owner FAILS unless declared in KNOWN_UNWIRED_METRICS (shrink-only);
+#       (4) `up{job="X"}` is audited separately — `up` itself always exists, so (1) is blind to
+#           this — by requiring that where this repo authors a Service and a ServiceMonitor in the
+#           SAME file, the monitor's endpoint port is a port that Service actually defines;
+#           violations must be declared in KNOWN_UNWIRED_JOBS (shrink-only);
+#   AND (5) the check is LOAD-BEARING: this test declares `conformance.home.k3s/scope: whole-repo`
+#           so ci/l0.sh unions it into every gate run, and ci/gate.sh blocks on an l0 failure.
+#
+# WHY THE REGISTERS ARE RATCHETS (the decision and its reasons) — the same three options as
+# alert-rules-unit-tested faced:
+#   * FAIL outright on all 13: correct in principle, but 12 of them are app SLI rules that need
+#     Prometheus exporters for Plex, Pi-hole, Jackett, qBittorrent, Sonarr, Radarr and Seerr —
+#     none of which speak Prometheus natively. The gate would be red for every change until that
+#     work lands, so it would get disabled, and a disabled gate protects nothing.
+#   * merely REPORT: that is precisely how these rules stayed inert across phases 4-6.
+#   * RATCHET (chosen): each gap is declared here, printed with counts on every run, and CANNOT
+#     GROW. A new alert on an unclaimed metric FAILS. A new same-file Service+ServiceMonitor pair
+#     with a mismatched port FAILS. A STALE entry — the gap was closed, or the alert deleted —
+#     also FAILS, so neither register can rot into fiction.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — this is a STATIC check):
+#   - It does not prove a target is UP, that an endpoint answers, that the chart still honours the
+#     values key, or that a NetworkPolicy is sufficient. Those were established by live prod reads
+#     recorded in the commit message: with the enablements applied, longhorn_volume_robustness
+#     returned 44 series, {__name__=~"certmanager.*"} returned 104, and all six new targets read
+#     up==1. A live probe needs a cluster, which L0 by definition does not have.
+#   - It cannot audit a ServiceMonitor whose Service is created by a Helm chart rather than by this
+#     repo: the port name lives outside the tree. That is why (4) is scoped to same-file
+#     Service+ServiceMonitor pairs — the apps/* ServiceDefinition pattern — and why the
+#     platform/* monitors (oauth2-proxy, kubevirt, keycloak, flux) are out of its reach. Their
+#     liveness is covered by the fact that their metrics have owners under (1).
+#   - IT PROVES THE SCRAPE TARGET, NOT THE SERIES NAME. An owner claims a metric by PREFIX, so a
+#     metric in a scraped family whose exact name the exporter does not emit still passes. This is
+#     a real residual hole and it was live in this repo: `kubevirt_vmi_phase_count{phase="Failed"}`
+#     (KubeVirtVMLaunchFailing) sat inside the scraped `kubevirt_` family on an UP target, and the
+#     series simply does not exist on the deployed KubeVirt — verified on prod 2026-09-13, where the
+#     only kubevirt_vmi_* names are `info` and `number_of_outdated`, and the only phase-bearing
+#     names are the phase_transition_time histograms. Corrected in the same change to
+#     `kubevirt_vmi_info{phase="failed"}` (note the LOWERCASE value KubeVirt writes: a capital-F
+#     matcher selects nothing and is just as inert). Catching that class needs the exporter's own
+#     metric list, which is a live read, not a static one — it belongs to a future L1/L3 check that
+#     diffs every alert metric against `/api/v1/label/__name__/values`. The same limit applies to
+#     every LABEL VALUE an alert matches on.
+#   - The metric-name parser is a PromQL approximation, not a parser: it strips string literals,
+#     label-matcher bodies and aggregation label lists, then treats remaining bare identifiers as
+#     metric selectors. A metric referenced ONLY through a `{__name__=~"..."}` regex selector would
+#     be missed. No rule in this repo does that, and assertion (0) fails if the parser stops
+#     finding metrics at all.
+#   - It does not judge thresholds, and does not prove an alert reaches a human (R-OBS-02 and the
+#     L3 alerting test own that).
+#   - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06).
+#
+# Exit 0 = all assertions pass. Exit 1 = a failure. Exit 3 (honest SKIP, and because this test
+# declares the whole-repo scope the runner turns it into rc 3 = UNWIRED, never green) only if the

+# it either — a target that was never discovered has no up series to be 0.
+#
+# IT HELD ALL TWELVE apps/* SLI RULES, AND IT IS EMPTY BECAUSE THEY WERE FIXED, not because the gap
+# was waived (2026-09-13, branch fix/app-sli-rules-discover-no-targets). The register's own note

+# premise: Plex, Pi-hole, Jackett, qBittorrent, Sonarr, Radarr, Seerr, Semaphore and Nextcloud
+# genuinely export no Prometheus metrics, so instead the `up` SLI was rewritten against a signal that
+# DOES exist for every workload — kube-state-metrics readiness of the service's own workload object
+# (`kube_deployment_status_replicas_available` / `kube_statefulset_status_replicas_ready`), and
+# `kubevirt_vmi_info{phase="running"}` for the VM. No exporter, no new scrape target; each rule is
+# unit-tested firing AND quiet (apps/wave-*/tests/app-slis.test.yaml) and each expression was
+# evaluated live on prod, where eleven of the twelve return no series on a healthy cluster and the

+# tests/l0-static/servicemonitor-ports-resolve. THAT is where a ServiceMonitor naming a port no
+# Service defines fails, with no alert rule required, resolving by selector across the whole tree
+# rather than by same-file adjacency, and with its resolver proven on fixtures so it cannot pass for

+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# R-OBS-04 ("the platform alerts on its own health") is implemented by PrometheusRule CRs, and
+# this repo has shipped both ways they fail SILENTLY:
+#   * PERMANENTLY FIRING — the CNPG primaries alert (fixed 2026-09-12), VPNTunnelDown before it;
+#   * STRUCTURALLY INERT — VeleroNoRecentBackup, whose `time() - <absent series>` yields no
+#     series, so a schedule that had NEVER backed up could not raise it. Prod ran with zero
+#     volume backups and nothing alerted, masked by a resources-only schedule completing
+#     cleanly every night (2026-09-12).
+# An inert rule and a correct rule are indistinguishable while the platform is healthy. Only
+# `promtool test rules` separates them, by constructing the bad state on purpose, offline.
+#
+# The unit tests were then written — and RUN BY NOTHING. promtool was not in the pinned
+# toolchain, no gate stage evaluated the files, and the two harnesses that grew up independently
+# each fetched an engine off the network mid-run if promtool was missing (a GitHub release
+# download in one, a prometheus container image in the other). Coverage that looks present and
+# is enforced nowhere is the failure mode this test ends.
+#
+# GIVEN the repository as authored,
+# WHEN  the ONE rule-unit harness (platform/monitoring/tests/run.sh, which flattens the
+#       COMMITTED PrometheusRule CRs into the rules file promtool wants — never a copy) is run
+#       over every test file in the repo with the PINNED promtool,
+# THEN  promtool is pinned in BOTH versions.env files in lockstep at the Prometheus version prod
+#       actually runs, baked into the image and installed on the CI runner; the promtool in use
+#       reports exactly that version; no harness acquires an engine at run time; there is
+#       exactly ONE harness; every rule-unit test file PASSES; the harness is proven able to
+#       FAIL by a mutated synthetic test on every run; and every alert rule with NO unit test is
+#       ENUMERATED in a shrink-only register, so the gap is reported rather than hidden.
+#
+# MISSING TESTS: RATCHET, NOT SKIP, NOT BLANKET-FAIL. 48 of 55 alert rules have no unit test
+# today. Failing on all of them would make the gate red until ~48 tests exist (so it would be
+# disabled, and a disabled gate protects nothing); merely reporting is precisely how the CNPG
+# tests came to be enforced by nothing. So the gap is DECLARED in check.sh, printed with counts
+# every run, and CANNOT GROW: a new PrometheusRule, or a new alert in an already-tested file,
+# FAILS without a test, and a stale register entry FAILS too. A missing test is never an exit-3
+# skip — "SKIPPED is not green" is preserved for the one thing that is genuinely an environment
+# gap: promtool being absent.
+#
+# STATUS: EXECUTABLE. `check.sh` is an offline assertion script (standard library + the harness
+# it delegates to); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this
+# Chainsaw Test wraps the SAME script.
+#
+# NOT proven (named in check.sh's header): that an alert reaches a human (Alertmanager routing
+# and SMTP are L3 / R-OBS-02), that a threshold is the right one, that a rule file is actually
+# reconciled into a cluster, or that an author's assertions are meaningful — coverage of one
+# alert is detected by its name appearing in a covering test file, and only the mutation
+# self-test proves the harness CAN fail. R-OBS-04 is tagged for the static slice only: the rules
+# the repo ships behave, under the engine prod runs, as their own unit tests say.

+# WHY THIS EXISTS — AN UNTESTED ALERT IS NOT A MONITORING CONTROL
+# --------------------------------------------------------------
+# This repo has shipped BOTH halves of the alerting failure space to prod:
+#   * a PERMANENTLY-FIRING `critical` (the CNPG alert fixed 2026-09-12; VPNTunnelDown before
+#     it), and
+#   * a STRUCTURALLY INERT rule — VeleroNoRecentBackup, whose `time() - <absent series>`
+#     yields no series, so a schedule that had NEVER backed up could not raise it. Prod ran
+#     with no volume backups at all and nothing alerted (2026-09-12).
+# Neither is visible from the expression, from `kubectl apply`, or from a healthy cluster: an
+# inert rule and a correct rule are indistinguishable while everything is fine. `promtool test
+# rules` is the only tool that separates them, because the BAD state can be constructed on
+# purpose. Unit tests for those rules were then WRITTEN — and evaluated by nothing: promtool
+# was not in the pinned toolchain, no gate stage ran the files, and each of the two harnesses
+# that existed acquired an engine off the network mid-run if one was missing. Coverage that
+# looks present and is never enforced is the failure mode this check ends.
+#
+# GIVEN the repository as authored,
+# WHEN  the ONE rule-unit harness (platform/monitoring/tests/run.sh, which flattens the
+#       COMMITTED PrometheusRule CRs — never a copy) is asked which manifests are under test
+#       and then run over every test file in the repo,
+# THEN  (1) promtool is a PINNED member of the toolchain: PROMTOOL_VERSION is declared in BOTH
+#           infra/devcontainer/versions.env and ci/versions.env and the two AGREE (the repo's
+#           lockstep rule), the Containerfile takes it as a build ARG, installs it from the
+#           pinned prometheus release and records it for provenance, dev.sh passes it, and the
+#           CI runner installs it for the l0 stage;
+#       (2) the promtool ACTUALLY IN USE reports exactly that pinned version — a unit test is
+#           evidence only if the engine matches the one prod evaluates rules with;
+#       (3) NO harness acquires a rule engine at RUN TIME — neither `curl | tar -xz` of a
+#           GitHub release nor a `podman/docker run` of a prometheus image. Both existed on
+#           2026-09-12 and both are removed; this is the regression guard;
+#       (4) there is exactly ONE harness. Two were written independently within an hour of
+#           each other; the one nothing runs is the one that rots;
+#       (5) every rule-unit test file in the repo PASSES, run through that harness (which
+#           `promtool check rules` first, so a non-parsing rules file cannot make unit tests
+#           pass vacuously by finding no rules at all);
+#       (6) the harness is NOT VACUOUS: a synthetic PrometheusRule + companion test is run
+#           through the SAME harness twice — intact (must PASS) and with one expectation
+#           mutated (must FAIL) — so a harness that has silently stopped evaluating anything
+#           is caught on every run, not only when someone thinks to try it;
+#   AND (7) the alert rules with NO unit tests are ENUMERATED and RATCHETED: each is declared
+#           below, printed with counts on every run, and the register can only SHRINK.
+#
+# WHY A MISSING TEST IS A RATCHET AND NOT AN OUTRIGHT FAIL (the decision, and its reasons)
+# ---------------------------------------------------------------------------------------
+# 48 of the repo's 55 alert rules have no unit test today. Three options were on the table:
+#   * FAIL on any missing test — correct in principle, but it makes the merge gate red for
+#     every change until ~48 unit tests exist, so in practice the gate gets disabled, and a
+#     disabled gate protects nothing.
+#   * merely REPORT — the gap prints and nothing holds it. That is exactly how the CNPG unit
+#     tests came to exist and be enforced by nothing; "it is in the output somewhere" is not
+#     enforcement.
+#   * RATCHET (chosen) — the gap is DECLARED IN THE REPO as a reviewable register, printed with
+#     counts on every gate run, and it CANNOT GROW: a new PrometheusRule, or a new alert in a
+#     file that already has tests, FAILS unless it ships a unit test. Removing an entry requires
+#     writing the test, and a STALE entry (file gone, or now covered) also FAILS, so the
+#     register cannot rot into fiction.
+# "SKIPPED is not green" is honoured: a missing test is NEVER an exit-3 skip here. This check
+# exits 0 only with the gap fully enumerated, and exits 1 the moment the debt grows, the
+# register drifts, or a test that exists stops passing.
+# The one exit-3 path is promtool itself being ABSENT — an environment gap, not a code property
+# (the same convention as ci/l0.sh's kyverno handling), and this test DECLARES
+# `conformance.home.k3s/scope: whole-repo`, which makes lib/run_l1_offline.py turn that skip
+# into the runner's rc 3 and ci/l0.sh into the gate's rc 3: UNWIRED, never green. promtool
+# PRESENT AT THE WRONG VERSION is a FAILURE, not a skip: that case still prints SUCCESS while
+# evaluating the rules with an engine prod does not run.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps):
+#   - It does not prove an alert reaches a human. promtool evaluates rules against synthetic
+#     series in-process; Alertmanager routing, SMTP delivery and inhibition are L3
+#     (tests/l3-fault-injection/alerting) and R-OBS-02, and are not claimed here.
+#   - It does not prove the THRESHOLDS are right, only that a rule behaves as its own unit
+#     test says.
+#   - It does not prove a rule file is RECONCILED into a cluster. An alert file no
+#     kustomization includes is a separate "looks applied and isn't" failure, not audited here.
+#   - Coverage of an individual alert is detected by its NAME appearing in a test file that
+#     covers its manifest. A test file that merely mentions a name without asserting anything
+#     counts as covered; only the mutation self-test (6) proves the harness CAN fail, not that
+#     every author wrote a meaningful assertion. Review still owns test quality.
+#   - It does not read the live cluster, so "the pin matches prod's Prometheus" is asserted
+#     against the repo's pin, which was established by a live read recorded in
+#     infra/devcontainer/versions.env (2026-09-12: v3.14.0-distroless).

+# L0 STATIC — every alert's runbook_url resolves to a runbook that is actually served
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# Every platform-health alert rule in this repo carries
+# `runbook_url: "https://${BASE_DOMAIN}/runbooks/<name>"` — 42 annotations across four files, over 34
+# distinct names. For the whole of phases 4-6 there was NO runbooks/ directory and NO HTTPRoute serving
+# that path: an in-cluster probe of https://home.keithjackson.dev/runbooks/node-down returned HTTP 404.
+# So an alert reaching a human handed them a dead link at the one moment documentation is read, while the
+# annotation made the problem look solved — the same green-surface-over-absent-mechanism class as the
+# import Job that reported success while storing placeholder secrets, and the guard whose glob silently
+# stopped matching.
+#
+# The link is served now (runbooks/, clusters/base/runbooks.yaml). This test is the guard that keeps it
+# true, and it asserts BOTH halves of the claim because the regression is silent in both directions: an
+# alert with a new runbook_url and no runbook links to a 404, AND a runbook committed without its
+# configMapGenerator entry is in git, reviewed, merged — and still 404s in the cluster. "The file exists"
+# and "the URL resolves" are different claims; only the second one helps an operator.
+#
+# GIVEN every `runbook_url` annotation on every PrometheusRule in the repo,
+# WHEN  each is parsed out of git and resolved against runbooks/,
+# THEN  (1) each URL has EXACTLY the shape the server resolves — https://${BASE_DOMAIN}/runbooks/<name>,
+#           the ${BASE_DOMAIN} token (never a literal hostname), no `.md`, no trailing slash, no query;
+#       (2) every referenced <name> has a runbooks/<name>.md in git;
+#       (3) each runbook clears a QUALITY FLOOR — the four operator sections, a real body, and the
+#           dev-container kubectl invocation with --context k3s-prod — so a stub cannot satisfy (2) and
+#           make the link look fixed while still helping nobody;
+#       (4) every runbook is PROJECTED INTO THE SERVER by runbooks/kustomization.yaml's
+#           configMapGenerator under the extensionless key the URL asks for;
+#       (5) route, listener and server agree with the annotations (PathPrefix == the annotations' prefix,
+#           a sectionName that platform/gateway/gateway.yaml actually defines, the namespace opted in to
+#           the Gateway, and an nginx location for that same prefix with a text/plain default_type);
+#       (6) the Flux tier is wired into clusters/base AND declares NO postBuild.substituteFrom —
+#           substitution would run envsubst over the runbook prose and silently empty every `${...}`
+#           shell example in it (it fails open: DECISIONS-LOG 2026-09-01, the emptied Cilium
+#           k8sServiceHost), and the flux-postbuild-substitution check cannot see it because that check
+#           scans files reachable through `resources:`, not configMapGenerator inputs;
+#   AND (7) the check is LOAD-BEARING: this Test DECLARES
+#           `conformance.home.k3s/scope: whole-repo`, so ci/l0.sh Stage 3b's
+#           `--include-scope whole-repo` unions it into EVERY gate invocation rather than only the runs
+#           whose touched requirements happen to include R-OBS-04; and ci/gate.sh sets the merge block
+#           when the l0 stage fails. A SKIP of a scope-declaring check is UNWIRED, never green.
+#
+# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (standard library only);
+# conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this Chainsaw Test wraps the SAME
+# script.
+#
+# NOT proven (named in check.sh's header): this does not FETCH the URL. That it returns HTTP 200 with
+# real content was proven by an in-cluster probe recorded in the commit message; a live probe needs a
+# cluster, which L0 by definition does not have. What is asserted here is every static precondition for
+# that 200. It also does not judge whether a runbook is correct or current — (3) is a floor, not a
+# review — and it does not prove Alertmanager delivers the annotation to a human (that is the L3
+# `alerting` test). R-OBS-04 is tagged for the narrow slice only: the platform's own health alerts carry
+# runbook links that resolve to real, served procedure rather than to a 404.

+#         VPN)." — spec docs/10-observability-and-alerting.md)
+#
+# WHY THIS EXISTS — A DEAD LINK IN AN ALERT IS WORSE THAN NO LINK
+# --------------------------------------------------------------
+# Every platform-health alert rule in this repo carries
+#   runbook_url: "https://${BASE_DOMAIN}/runbooks/<name>"
+# 42 such annotations across four files, over 34 distinct names. For the whole of phases 4-6
+# there was NO runbooks/ directory and NO HTTPRoute serving that path: a live in-cluster probe
+# of https://home.keithjackson.dev/runbooks/node-down returned HTTP 404. So an alert reaching a
+# human at 3am handed them a link that fails, at the one moment the documentation is read. The
+# annotation LOOKED like the problem was solved, which is the specific failure this repo keeps
+# finding (an import Job that reports success while storing placeholder secrets; a guard whose
+# glob silently stopped matching) — a green-looking surface over an absent mechanism.
+#
+# The link is now served (runbooks/, clusters/base/runbooks.yaml). This check is the guard that
+# keeps it true, because the regression is SILENT IN BOTH DIRECTIONS and nothing else catches it:
+#   * add an alert with a new runbook_url and forget the runbook  -> that alert links to a 404,
+#     and no test, lint, render or policy notices;
+#   * write runbooks/<name>.md but forget to add it to the ConfigMap generator -> the file is in
+#     git, reviewable, apparently done, and the URL still 404s in the cluster. "The file exists"
+#     and "the URL resolves" are different claims and only the second one helps an operator.
+# Both halves are asserted below, which is why this check reaches past the markdown into the
+# kustomization, the HTTPRoute, the nginx config and the Flux tier.
+#
+# GIVEN the repository as authored,
+# WHEN  every `runbook_url` annotation on every PrometheusRule is parsed out of git,
+# THEN  (1) each URL has EXACTLY the shape the server resolves —
+#           https://${BASE_DOMAIN}/runbooks/<name>, `${BASE_DOMAIN}` as the token (never a literal
+#           hostname: a literal is how prod was authored to serve dev's hostnames, see the
+#           ServiceDefinition schema's note), no `.md` suffix, no trailing slash, no query;
+#       (2) every referenced <name> has a runbooks/<name>.md in git;
+#       (3) each runbook clears a QUALITY FLOOR — the four operator sections, a real body, and the
+#           dev-container kubectl invocation — so a one-line stub cannot satisfy (2) and make the
+#           link look fixed while still helping nobody (the failure mode this check is most likely
+#           to be defeated by is a placeholder file, not a missing one);
+#       (4) every runbook markdown file is actually PROJECTED INTO THE SERVER by
+#           runbooks/kustomization.yaml's configMapGenerator, under the EXTENSIONLESS key the URL
+#           asks for — the "exists in git but 404s in the cluster" half;
+#       (5) the route and the server agree with the annotations: the HTTPRoute's PathPrefix is the
+#           prefix the URLs use, it attaches to a Gateway listener that actually exists, its
+#           namespace is opted in to that Gateway, and the nginx config answers that same prefix;
+#       (6) the Flux tier that reconciles all of it is wired into clusters/base AND declares NO
+#           postBuild.substituteFrom — substitution here would run envsubst over the runbook prose
+#           and silently empty every `${...}` shell example in it (it fails open: DECISIONS-LOG
+#           2026-09-01, the emptied Cilium k8sServiceHost);
+#   AND (7) this check is LOAD-BEARING: ci/l0.sh runs it on every gate run and ci/gate.sh sets the
+#           merge block when the l0 stage fails.
+#
+# WHY (7) IS AN UNCONDITIONAL ci/l0.sh STAGE and not left to the requirement-scoped run: Stage 3b
+# scopes `conformance/run.sh --layer l0` to the TOUCHED requirements (R-TEST-03), and
+# ci/touched-requirements.sh maps platform/monitoring/* to "R-OBS-01 R-OBS-02" — NOT R-OBS-04 — and
+# maps platform/kubevirt/* and runbooks/* to nothing at all. So the single most likely breaking
+# change (adding an alert with a runbook_url to platform/monitoring/alerts.yaml, or adding a
+# runbook and forgetting the generator entry) attributes a requirement set that would FILTER THIS
+# CHECK OUT. Declaring `conformance.home.k3s/scope: whole-repo` makes ci/l0.sh Stage 3b union it into
+# EVERY gate invocation instead; a SKIP of a scope-declaring check is UNWIRED, never green.
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — this is a STATIC check):
+#   - It does not fetch the URL. That it returns HTTP 200 with real content was proven by an
+#     in-cluster probe (recorded in the commit message and DECISIONS-LOG); a live probe needs a
+#     cluster, which L0 by definition does not have. What is asserted here is every static
+#     precondition for that 200: the file, its projection, the key name, the route, the prefix.
+#   - It does not judge whether a runbook is CORRECT or current. (3) is a floor, not a review: it
+#     can tell a stub from a runbook, not a good runbook from a stale one. Nothing automatable can.
+#   - It does not prove Alertmanager actually delivers the annotation to a human. That is the L3
+#     `alerting` test.
+#   - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06) and is not consulted.

+#
+# WHY L0, AND NOT L2
+# ------------------
+# The REACHABILITY half of R-C2-01 is already exercised against a live cluster:
+# l2-behavioral/gateway-ingress-reachable dials the Gateway and l2-behavioral/trusted-tls
+# verifies the certificate it serves. What no live probe can decide is the half the
+# requirement is actually about — whether the UI at the root surfaces THE SERVICES RUNNING
+# IN THE CLUSTER. Deciding that is a comparison of two SETS, and both are repository facts:
+# what git declares the cluster serves (every in-repo HTTPRoute hostname, every L4 Service
+# that publishes a hostname, every catalog ServiceDefinition) against what the dashboard's
+# ConfigMap links. A probe of the root gets HTTP 200 from a dashboard that hides half the
+# estate and cannot tell the difference.
+#
+# It is also the assertion that ROTS, in the direction nothing else notices: onboard a
+# service, forget the dashboard, and every cluster test stays green while the operator's
+# front door hides a running service. That is not a styling preference — it is exactly the
+# R-C2-01 failure mode, and this check found a live instance of it when it was written (see
+# the commit message: platform/crafty served crafty.${BASE_DOMAIN} and nothing on the root
+# linked to it).

+#     because the Gateway ext-authz attachment that would enforce forward-auth is not built
+#     anywhere in this repo (platform/homepage/httproute.yaml says so in its own header, and
+#     every forward-auth app shares the gap). Declared, not enforced — and labelled as such
+#     in the assertion text.
+#   - That an operational action in the console succeeds, or that it is audited. The
+#     assertions prove there is no shared cluster-admin identity to act with and that rights
+#     arrive per-user; the audit trail is a runtime property.
+#   - Whether a tile is USEFUL. Homepage service-widget API keys are a deliberate follow-up

+# L0 static check (offline, no cluster) — c2-root-surface
+#
+# Serves (spec docs/00-vision-and-scope.md; detail in docs/12-command-center-ui.md):
+#
+#   R-C2-01  "The root `home.keithjackson.dev` MUST serve a UI that surfaces the
+#             services running in the cluster and links to them."
+#   R-C2-02  "The C2 UI MUST surface platform health (cluster, storage, GitOps,
+#             alerts) and provide controlled operational actions where safe."
+#
+# WHY THIS IS AN L0 STATIC CHECK AND NOT AN L2 PROBE
+# --------------------------------------------------
+# The REACHABILITY half of R-C2-01 is already exercised against a live cluster:
+# l2-behavioral/gateway-ingress-reachable dials the Gateway and l2-behavioral/trusted-tls
+# verifies the certificate it serves. What no live probe can decide is the half the
+# requirement is actually about — whether the UI at the root surfaces THE SERVICES RUNNING
+# IN THE CLUSTER. Deciding that is a comparison of two SETS, and both are repository facts:
+# what git declares the cluster serves (every in-repo HTTPRoute hostname, every
+# hostname-publishing L4 Service, every catalog ServiceDefinition) against what the
+# dashboard's ConfigMap links. A probe of the root gets HTTP 200 from a dashboard that hides
+# half the estate and cannot tell the difference.
+#
+# It is also the assertion that ROTS, in the direction nothing else notices: onboard a
+# service, forget the dashboard, and every cluster test stays green while the operator's
+# front door hides a running service. That is not a styling preference — it is exactly the
+# R-C2-01 failure mode, and it was a LIVE defect on main when this check was written
+# (platform/crafty served crafty.${BASE_DOMAIN} and nothing on the root linked to it).
+#
+# THE RULE THIS IMPLEMENTS, in one sentence: every home-zone hostname the repository routes
+# over HTTP must be linked from the apex dashboard's configuration, every home-zone link the
+# apex dashboard offers must resolve to something the repository actually serves, and the two
+# R-C2-02 surfaces (health data + a per-user-authorized console) must be linked, reconciled
+# and backed by real alert rules.
+#
+# GIVEN the repository as git tracks it,
+# WHEN  the apex ingress chain, the dashboard's declared link set, every in-repo HTTPRoute,
+#       every hostname-publishing L4 Service, the versioned catalog, the platform-health
+#       alert rules and the console's RBAC posture are read and compared,
+# THEN — R-C2-01 —
+#       (0)  the INPUT SURFACE is intact: every Flux-reconciled path lies inside the roots
+#            this check scans, and every manifest in them parses. A root this check does not
+#            scan, or a file it cannot parse, is a service it cannot see — which would
+#            silently weaken every assertion below;
+#       (1)  EXACTLY ONE HTTPRoute claims the bare apex (an ambiguous root is not a root),
+#            and it belongs to the landing-dashboard component;
+#       (2)  that route pins by sectionName the ONE Gateway listener whose hostname is the
+#            bare apex, and that listener is HTTPS — the wildcard `*.${BASE_DOMAIN}` listener
+#            does NOT intersect the bare apex, so without the sectionName the root binds
+#            nothing and serves nothing (asserted against the wildcard listener's existence,
+#            so the claim is proven rather than asserted from prose);
+#       (3)  the apex is a SAN on the Certificate whose Secret that listener terminates with;
+#       (4)  the dashboard is RECONCILED, not merely authored: one Flux Kustomization points
+#            at its path and is listed in the base entrypoint set;
+#       (5)  that Kustomization carries postBuild.substituteFrom, because the dashboard's
+#            hrefs and its route's hostname are written as `${BASE_DOMAIN}` tokens — without
+#            substitution the apex route binds a literal `${BASE_DOMAIN}` and EVERY tile on
+#            the root links to a nonexistent host, while Flux still reports Ready;
+#       (6)  the component's own kustomization ships config + workload + Service + route;
+#       (7)  the dashboard is a service CATALOG: grouped entries carrying hrefs;
+#       (8)  FORWARD — every home-zone hostname an in-repo HTTPRoute serves, other than the
+#            apex itself, is LINKED from the root. This is the rot-catcher;
+#       (9)  FORWARD — every catalog `kind: container` ServiceDefinition whose declared
+#            ingress host is routed is likewise linked, tying the C2 to the VERSIONED
+#            onboarding contract and not only to whatever is rendered today;
+#       (10) REVERSE — every home-zone link the root offers resolves to something this repo
+#            actually serves: an HTTPRoute (L7) or a hostname-publishing LoadBalancer Service
+#            (L4). A dead tile is a link the root offers to nothing;
+#       (11) the off-cluster escape hatch is not a blanket one: every name declared in the
+#            ConfigMap's `off-cluster-links` annotation is a specific home-zone hostname and
+#            none of them shadows a hostname the repo DOES serve;
+#       (12) no href names a LITERAL base-domain host. Every hostname is the `${BASE_DOMAIN}`
+#            token, so prod's root cannot link dev's services — the 2026-09-04 incident class
+#            (two clusters authored to describe the same names), applied to the front door;
+#     — R-C2-02 —
+#       (13) both health surfaces docs/12 names are linked: the Kubernetes console
+#            (cluster/storage/GitOps state) and the dashboards/alerts surface;
+#       (14) both are RECONCILED by Flux, so the links lead to something running;
+#       (15) the health DATA those surfaces render exists as code — PrometheusRule groups for
+#            each axis R-C2-02 enumerates (cluster/nodes, storage, GitOps reconciliation)
+#            plus certificate expiry — and those rule files are reconciled;
+#       (16) actions are CONTROLLED, not cluster-admin-in-a-browser (docs/12: "never a raw
+#            cluster-admin kubeconfig in a browser"): the console chart is explicitly told NOT
+#            to bind its ServiceAccount to a ClusterRole, so there is no shared privileged
+#            identity to act as;
+#       (17) actions are instead PER-USER: the console is configured for native OIDC with
+#            credentials from a named (SOPS) Secret, not inline;
+#       (18) cluster rights arrive through OIDC GROUPS at MORE THAN ONE privilege level (an
+#            admin group and a lesser one) — least-privilege, not one tier for everybody;
+#       (19) the C2 root DECLARES the authenticated-group posture docs/12 requires, on its own
+#            route (declared, NOT enforced — see the gap note below).
+#
+# WHAT THIS DOES *NOT* PROVE — honest gaps, the same ones the Test declaration names:
+#   - That the apex answers HTTP 200, or that any tile's status ping is green. That is L2; the
+#     Gateway/TLS half is covered under R-DNS-01 / R-TLS-01.
+#   - That the C2 is access-CONTROLLED in fact. (19) reads a DECLARED posture, because the
+#     Gateway ext-authz attachment that would ENFORCE forward-auth is not built anywhere in
+#     this repo (platform/homepage/httproute.yaml says so in its own header, and every
+#     forward-auth app shares the gap). Declared, not enforced, and labelled as such in the
+#     assertion text itself.
+#   - That an operational action in the console succeeds, or that it is audited. (16)-(18)
+#     prove there is no shared cluster-admin identity to act with and that rights arrive
+#     per-user; the audit trail is a runtime property.
+#   - Whether a tile is USEFUL. Homepage service-widget API keys are a deliberate follow-up
+#     (platform/homepage/configmap.yaml); link presence is what R-C2-01 asks for.
+#   - That an L4-ONLY endpoint is surfaced. A raw TCP/UDP endpoint (a Minecraft game port) has
+#     no URL a browser can follow, so the FORWARD direction quantifies over HTTP routes;
+#     L4-published hostnames are listed as ADVISORIES and are honoured in the REVERSE
+#     direction (that is how the UniFi tile, an L4 LoadBalancer on :11443, resolves).
+#   - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06) and the
+#     requirement text above is quoted, not parsed.

+# ------------------------------------------------------------------
+# The first incident was a variable the author wanted EXPANDED that rendered EMPTY. This one
+# is its mirror: content the author wanted to reach the workload UNTOUCHED that substitution
+# silently REWROTE. A CronJob reconciler in apps/wave-0/nextcloud-db.yaml asserted its own
+# convergence in a dollar-quoted PL/pgSQL block —
+#
+#     DO <dq> BEGIN ... END <dq>;     where <dq> is two literal dollars: standard Postgres
+#
+# — inside a ConfigMap under apps-wave-0, which declares postBuild.substituteFrom. envsubst
+# collapses a doubled dollar into ONE dollar, ALWAYS, so Postgres received a half-quoted
+# `DO <one dollar>` and died with `syntax error at or near "$"`. Three scheduled runs left
+# nine Error pods in nextcloud-db before anyone looked.
+#
+# It PASSED verification because it was hand-applied with `kubectl apply`, which runs NO
+# envsubst. The defect existed ONLY on the Flux-rendered path. And the damage landed
+# precisely on the self-check: the GRANT on line 1 still ran, so the privilege stayed
+# correct and the only thing broken was the assertion meant to make a silent regression
+# visible — the part whose whole job is to stop a blind spot being quiet.
+#
+# THE ASSERTION GAP THIS CLOSES: assertions (1)-(3) below ask whether every `${...}` is
+# defined, escaped, or parseable. They said NOTHING about a doubled dollar that is not an
+# escape, because the old classifier treated a `$` run of length >= 2 as "escaped, therefore

+# TWO CONSEQUENCES THIS CHECK IS BUILT ON:
+#   (a) THERE IS NO WAY TO SHIP A LITERAL `$$` THROUGH A SUBSTITUTED PATH. To make two
+#       dollars arrive you must author FOUR. So any authored `$$` that is meant to reach the
+#       workload verbatim is a BUG, full stop — that is the 2026-09-13 incident, and Postgres
+#       dollar-quoting is its commonest shape (Makefile `$$@`, awk `$$2` and docker-compose
+#       `$${}` are the same hazard arriving from the other direction: there the collapse is
+#       what the author wanted).
+#   (b) `$$$` + brace is NOT "more escaped" than `$$` + brace — it is NOT escaped at all. An
+#       odd run leaves one live dollar, so the brace expands, or, for an inner envsubst
+#       cannot parse, fails the ENTIRE Kustomization (proven above with $$${ARR[0]}, which
+#       aborted the whole stream while $${ARR[0]} on the line before it was fine).
+# `--strict` reports NONE of this: every row of that table except the parse error was
+# accepted SILENTLY by `flux envsubst --strict`, exit 0, and its output was BYTE-IDENTICAL to
+# non-strict (`cmp`). Strict mode cannot see this class, so a source-level assertion is the

+# permanently-firing alert on documented, correct intent, and this repo has already been
+# bitten by one of those.
+#
+# EVERY OTHER run of >= 2 dollars FAILS unless it is named in `dollar-collapse.allow`:
+#   * DOLLAR-COLLAPSE   — a run not followed by `{`. Cannot survive verbatim: `$$` -> `$`.
+#                         This is the incident's exact shape and a blanket bug by default.
+#   * DOLLAR-HALF-ESCAPED — an ODD run >= 3 before `{`. Looks escaped, is not: the last
+#                         dollar is live. Occasionally legitimate (`$$${PRICE}` to render a

+#
+# WHY THIS FILE EXISTS
+# --------------------
+# Flux's postBuild substitution runs github.com/fluxcd/pkg/envsubst (Flux's fork of
+# github.com/drone/envsubst; the module path is embedded in the pinned flux 2.4.0
+# binary, and check.sh's header says how to read it back out) over everything a
+# substituted Kustomization renders, and that scanner consumes dollars in PAIRS,
+# emitting ONE dollar per pair — unconditionally, wherever they appear, not only in
+# front of a brace. A run of N dollars becomes floor(N/2) dollars, and an ODD run
+# leaves one live dollar behind (so `$$${X}` is NOT escaped; it expands).
+#
+# Consequence: there is NO way to ship a literal `$$` through a substituted path.
+# On 2026-09-13 that broke the nextcloud-db grant reconciler — a dollar-quoted
+# PL/pgSQL `DO $$ ... $$;` block reached Postgres as `DO $ ... $;` and every
+# Flux-reconciled run died with `syntax error at or near "$"`. It had passed review
+# because it was hand-applied with `kubectl apply`, which runs no envsubst at all.
+# See commit 16b7fcd and check.sh's DOLLAR-RUN ARITHMETIC table (measured against
+# flux 2.4.0, not inferred).
+#
+# From the source text alone, a doubled dollar the author WANTS collapsed and one
+# that must arrive verbatim are indistinguishable. check.sh therefore accepts exactly
+# one shape without comment — a run of EXACTLY TWO dollars immediately followed by
+# `{`, the escape contract clusters/base/apps-vms.yaml already documents and that 18
+# reviewed occurrences already depend on — and FAILS every other run of two or more
+# dollars unless it is named here.
+#
+# ADDING AN ENTRY IS A DECISION, NOT A MUTE BUTTON
+# -----------------------------------------------
+# One entry per line, exactly three `|`-separated fields:
+#
+#     <repo-relative path> | <verbatim context> | <reason>
+#
+#   * the context must be a VERBATIM substring of the file AS STORED IN GIT (for a
+#     folded/JSON-ish scalar that means the escaped bytes, e.g. `\n` and `—`
+#     spelled literally), at least 24 characters long, containing the dollar run it
+#     excuses, and containing no `|` — shift the window if a pipe is in the way;
+#   * the reason must be at least 40 characters and should say what envsubst will
+#     actually EMIT and why that is acceptable;
+#   * an entry covers only the dollar runs inside the region its context matches, so
+#     it can never silently cover a new occurrence that lands elsewhere in the file;
+#   * check.sh FAILS a stale entry — one whose context no longer matches, or which
+#     excuses nothing any more. Delete it rather than leaving it to rot into a
+#     blanket exemption for whatever lands in that file next.
+#

+# L0 STATIC — no service declared `internal` can produce a PUBLIC DNS record
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# THE DEFECT THIS CLOSES. docs/09 R-DNS-03 says `internal` services are unreachable from the
+# public internet, that external names resolve to the PUBLIC IP, and that Pi-hole provides the
+# internal split-horizon answers. schemas/renderer-contract.md §exposure says an `internal`
+# service renders "no public DNS record". NOTHING ENFORCED EITHER SENTENCE. ExternalDNS
+# (platform/externaldns/helmrelease.yaml, `sources: [gateway-httproute, service]`,
+# `policy: sync`, provider cloudflare) considered EVERY HTTPRoute on the shared Gateway, so six
+# `exposure: internal` services — jackett, pihole, qbittorrent, radarr, semaphore, sonarr — each
+# published `<name>.home.keithjackson.dev` into the PUBLIC authoritative Cloudflare zone,
+# answering with the Gateway VIP 192.168.2.20. Verified at the authority on 2026-09-14; the
+# pre-state is committed at .standup-dns/dns-20260914-pre-externaldns-scope.txt.
+#
+# Three things were wrong at once, and none of them was visible from inside the cluster:
+#   * the internal subnet, the Gateway VIP and a complete service inventory were publicly
+#     enumerable by anyone who could guess or brute-force a label;
+#   * a public name answering with an RFC1918 address IS a DNS-rebind primitive, which is why the
+#     SOHO router at 192.168.2.1 strips those answers and LAN clients need per-client dnsmasq
+#     overrides to reach their own services;
+#   * the guarantee was only ever prose. `exposure` was the operator's one declaration of intent
+#     and it had NO effect on DNS whatsoever, so "internal" meant nothing an attacker had to
+#     respect.
+#
+# WHY THE FIX NEEDS A GUARD AND NOT JUST A COMMIT. The mechanism is an annotation on a rendered
+# HTTPRoute. An annotation is exactly the kind of thing that survives review by looking harmless
+# and then disappears in a refactor of `_route_meta`, a hand-edit of apps/, or a new service added
+# by copying a public one. Nothing about its ABSENCE is loud: the service keeps working on the LAN,
+# the Kustomization stays Ready, and the only symptom is a public record nobody is looking at. The
+# 2026-09-13 ServiceMonitor incident in this same tree is the precedent — twelve monitors pointed
+# at a port that did not exist for weeks, silently, because the only thing asserting the wiring was
+# prose. This test makes the DNS guarantee a gate condition instead.
+#
+# GIVEN every ServiceDefinition in catalog/ and every HTTPRoute and external-dns-annotated
+#       Service this repo authors,
+# WHEN  each catalog service's rendered routes are resolved in the applied tree (apps/),
+# THEN  (1) every route of an `exposure: internal` service carries ExternalDNS's own controller
+#           annotation set to something OTHER than `dns-controller`, which external-dns v0.21.0
+#           uses to skip the source object outright (source/gateway.go ->
+#           annotations.IsControllerMismatch, checked before any hostname is resolved), so the
+#           route cannot become an endpoint for ANY name it declares;
+#       (2) NO route of an `exposure: public` service carries it — asserted explicitly, because a
+#           renderer that stamped every route would satisfy (1) perfectly while silently
+#           withdrawing the five public services' records, and `policy: sync` would delete them;
+#       (3) the same holds for the `service` source: an internal service's rendered Service may
+#           not carry an external-dns hostname annotation without the disown annotation beside it.
+#           Two sources are configured, so closing only the route half is half a guarantee;
+#       (4) the annotation is DERIVED FROM `exposure` in catalog/render.py and from nothing else —
+#           the emitting function must read `exposure`, must not name any catalog service, and
+#           must not be able to emit external-dns's own `dns-controller` value (the one value that
+#           CLAIMS a route rather than releasing it, inverting the guarantee while looking
+#           plausible). A per-service list is how twelve ServiceMonitors acquired one identical
+#           wrong port name in a single edit;
+#       (5) THE RENDERER IS PROVEN END-TO-END on synthetic ServiceDefinitions, by invoking the
+#           SHIPPED catalog/render.py as a subprocess: an `internal` fixture must yield the
+#           annotation, a `public` fixture must not, and a fixture that OMITS `exposure` must also
+#           yield it (the contract's default posture is `internal`, and omitting the field is the
+#           likeliest way a new service arrives). Without this the check would still pass if the
+#           renderer stopped working and someone hand-maintained apps/;
+#       (6) every HTTPRoute or annotated Service in the tree that the catalog does NOT render is
+#           DECLARED in KNOWN_NON_CATALOG_PUBLISHERS with what it publishes and why it is out of
+#           scope. Those are hand-authored platform/apps manifests with no `exposure` field for a
+#           renderer to read, and they are the seven names that REMAIN publicly advertised with an
+#           RFC1918 answer after this change. The register is shrink-only: an entry that stops
+#           matching a real object FAILS as stale, so the set of unadjudicated publishers cannot
+#           quietly grow, and adding a new one is a review event;
+#   AND (7) the check is LOAD-BEARING: this Test DECLARES `conformance.home.k3s/scope: whole-repo`,
+#           so ci/l0.sh Stage 3b's `--include-scope whole-repo` unions it into EVERY gate run, and
+#           ci/gate.sh blocks the merge when the l0 stage fails. It deliberately adds NO stage to
+#           ci/l0.sh — tests/l0-static/whole-repo-invariants-wired fails the gate if anyone does.
+#
+# WHY SCOPE, NOT REQUIREMENTS: ci/touched-requirements.sh's path map keys apps/* to NOTHING, and
+# apps/ is exactly where the rendered routes live. A requirement-scoped selection would therefore
+# filter this check out of the change most likely to break it — a hand-edit of a rendered route.
+# Same reasoning as its whole-repo siblings.
+#
+# STATUS: EXECUTABLE. `check.sh` is an offline assertion script (PyYAML, as catalog/render.py and
+# the sibling l0-static checks use); conformance/run.sh --layer l0 and ci/l0.sh run it directly,
+# and this Chainsaw Test wraps the SAME script.
+#
+# NOT proven (honest gaps; this is static, and it runs with no cluster and no network):
+#   - That the record is actually GONE from Cloudflare. That is a live read against an external
+#     authority and belongs in L2 beside conformance/tests/l2-behavioral/dns-exposure, which owns
+#     the positive direction (a public name DOES appear). The negative direction was proven
+#     MANUALLY on prod against the deployed v0.21.0 before this landed — a throwaway HTTPRoute
+#     carrying the annotation produced no record at all, and adding the annotation to a route that
+#     already had one produced `action=DELETE` for both its A record and its `a-` TXT registry
+#     entry within one ~60s reconcile — but a manual proof is not a gate.
+#   - That an `internal` name is unreachable from the internet. No DNS record is necessary for
+#     reachability; a port-forward plus a hardcoded IP still reaches the Gateway. This check owns
+#     the NAME axis only. R-NET-04 / the edge port-forward posture owns the other.
+#   - Anything about the seven non-catalog publishers' own correctness. The register records WHAT
+#     each publishes so the claim is reviewable, which is all a static check can offer.
+#   - Anything about the five `public` services' TARGET. They still resolve to the Gateway VIP
+#     rather than a routable address; that is an open operator decision recorded in
+#     platform/externaldns/helmrelease.yaml, and asserting a target here would hard-code a guess.
+#   - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06).

+# =============================================================================
+# L0 STATIC CHECK — no service declared `internal` can produce a PUBLIC DNS record.
+# See chainsaw-test.yaml's header for the full WHY. In one paragraph:
+#
+# docs/09 R-DNS-03 and schemas/renderer-contract.md §exposure both say an `internal` service
+# renders no public DNS record. Nothing enforced it: ExternalDNS watched every HTTPRoute on the
+# shared Gateway, so six internal services published `<name>.home.keithjackson.dev` into the
+# public Cloudflare zone answering with the RFC1918 Gateway VIP (verified at the authority
+# 2026-09-14; pre-state committed at .standup-dns/dns-20260914-pre-externaldns-scope.txt). The fix
+# derives ExternalDNS's controller annotation from `exposure` in catalog/render.py; this check is
+# what keeps it derived, present, and scoped.
+#
+# ASSERTIONS
+#   (0) the inventory is non-empty and the parse contract holds (anti-vacuous-pass);
+#   (1) every rendered route of an `internal` service carries the disown annotation;
+#   (2) NO rendered route of a `public` service carries it — a renderer stamping everything would
+#       satisfy (1) and silently delete the five public records under policy: sync;
+#   (3) the `service` source half: an internal service's Service may not carry an external-dns
+#       hostname annotation without the disown annotation beside it;
+#   (4) catalog/render.py DERIVES the annotation from `exposure` — the emitting function reads that
+#       field, names no catalog service, and cannot emit external-dns's own `dns-controller`;
+#   (5) the SHIPPED renderer is proven end-to-end on synthetic ServiceDefinitions (internal,
+#       public, and `exposure` OMITTED — the contract's default posture is internal);
+#   (6) every HTTPRoute / annotated Service the catalog does NOT render is declared in
+#       KNOWN_NON_CATALOG_PUBLISHERS — shrink-only, stale entries FAIL;
+#   (7) the check is LOAD-BEARING: whole-repo scope declared in chainsaw-test.yaml, honoured by
+#       ci/l0.sh's --include-scope union, and ci/gate.sh blocks on an l0 failure. NO hand-written
+#       ci/l0.sh stage (whole-repo-invariants-wired fails the gate if one appears).
+#
+# WHAT THIS DOES *NOT* PROVE (honest gaps — it is STATIC, offline, cluster-free):
+#   - That the record is gone from Cloudflare. Live read; belongs beside
+#     conformance/tests/l2-behavioral/dns-exposure, which owns the positive direction. The negative
+#     direction was proven manually on prod against the deployed v0.21.0 (a route carrying the
+#     annotation produced no record; adding it to a route that had one produced action=DELETE for
+#     both the A and its `a-` TXT within ~60s) — but a manual proof is not a gate.
+#   - That an internal name is UNREACHABLE. A port-forward plus a literal IP needs no DNS record.
+#     This check owns the NAME axis only.
+#   - Anything about the five public services' TARGET. They still answer with the Gateway VIP; the
+#     routable-target decision is open and recorded in platform/externaldns/helmrelease.yaml.
+#   - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06).
+#
+# Exit 0 = all assertions pass. Exit 1 = a failure. Exit 3 (honest SKIP, which the runner turns
+# into rc 3 = UNWIRED, never green, because this test declares the whole-repo scope) only if
+# catalog/ or apps/ is absent — i.e. the subject tree has vanished, which is not a pass.
