Operator rule 2026-10-29: image creation, hosting and lifecycle belong to CI/CD, never to a
workstation build/push. Nothing had ever been pushed to the Gitea registry.
- .gitea/workflows/images.yaml + scripts/images.sh: PRs build+verify (no credential); main
builds, verifies and pushes toolbox, agent-runner (FROM toolbox) and conformance-runner as
sha-<commit> + main, reading the digest back from the registry. Only changed images build.
- Each image's own build-image.sh does the build and in-image verification, now engine-neutral
(DinD: no podman-only calls, probe over stdin not a bind mount). New toolbox build-image.sh.
- Digest references carry `# renovate-digest:` markers; renovate.json5 gains a custom.regex
manager for them. The worker Job template is deliberately untracked (it would loop).
- renovate.yaml pins renovate-version 44.167.0: the action's default (39.264.0) rejects the
current config's managerFilePatterns, so every run would have died at CONFIG_VALIDATION.
- Push credential: REGISTRY_PUSH_TOKEN secret; the Actions token has no package scope in
Gitea 1.24.3 (container.go Authenticate). Retention: infra/gitea/registry-retention.sh.

The CNPG alert unit tests (324 lines, mutation-checked) were run by NOTHING. promtool was
not in the baked toolchain, no gate stage evaluated any *.promtool-test.yaml, and the only
runner `curl | tar -xz`'d a promtool release from GitHub at TEST-RUN time if one was
missing. Hours later a second, independent harness landed for the Velero rules
(platform/monitoring/tests/) with its own fallback — a `podman run` of
quay.io/prometheus/prometheus. So the repo had two harnesses, two acquisition paths, and
coverage that looked present and was enforced nowhere: the exact failure mode that had just
produced a permanently-firing CNPG alert and a structurally inert Velero alert.
PROMTOOL IS NOW PINNED LIKE EVERY OTHER TOOL. PROMTOOL_VERSION=3.14.0 in
infra/devcontainer/versions.env and ci/versions.env (the two stay in lockstep, per the
repo's rule), baked by the Containerfile from the prometheus release tarball (promtool ships
inside it), recorded in /etc/dev-toolchain-versions, passed by dev.sh, and installed for the
l0 stage by .gitea/workflows/scripts/install-tools.sh so the CI runner is not permanently
SKIPPED. The pin is not free-floating: promtool IS the rule engine, so it tracks the
Prometheus prod actually runs — verified against the live cluster, not assumed:
kubectl --context k3s-prod get prometheus -n monitoring -o jsonpath='{.items[*].spec.version}'
-> v3.14.0-distroless (image quay.io/prometheus/prometheus:v3.14.0-distroless)
ONE HARNESS. platform/cnpg/run-alert-tests.sh is folded into
platform/monitoring/tests/run.sh, which now covers every PrometheusRule in the repo that has
tests, via two conventions it discovers automatically: `<manifest>.promtool-test.yaml`
beside its manifest (cnpg), and `<component>/tests/*.test.yaml` over that component's
manifests (monitoring). It writes the flattened rules under whatever name each test file's
own `rule_files:` declares, so no test file needs to know the harness exists, and it
`promtool check rules` first — a rules file that does not parse would make every unit test
pass vacuously by finding no rules at all. The cnpg script's reasoning is preserved: why a
CR must be flattened (`.spec.groups`, never re-typed), and why generated files go to a temp
dir. Its `${BASE_DOMAIN}` substitution is dropped in favour of extract_rules.py's verbatim
placeholders, with the trade-off recorded there — the hazard it guarded against is addressed
by the temp dir, and verbatim leaves one transformation fewer between the shipped rule and
the rule under test.
NO ENGINE IS ACQUIRED AT RUN TIME any more — not the GitHub release, not the container
image. Not because a pinned download is unusual here (the Containerfile downloads every tool
it bakes) but because those two decided the version, the network and the machine SILENTLY,
at test time, on whatever host ran the tests; and each quietly turned "the toolchain has no
promtool" into a green run, which is how the toolchain stayed without one. Missing promtool
is exit 3 (UNWIRED, never green); a PROMTOOL= that does not resolve is exit 2.
ONE WIRING: conformance/tests/l0-static/alert-rules-unit-tested, NOT a gate stage. The
`prom-rules` stage (ci/prom-rules.sh + its Makefile target + ci/gate.sh entry) is deleted:
it is the bespoke-per-check pattern b9f8807 had just removed from ci/l0.sh, and the
declarative replacement gives what a hand-written stage cannot — selection by
`conformance.home.k3s/scope: "whole-repo"` (asserted: the test is selected even under a
requirement filter matching nothing), requirement-attributed JUnit/coverage/ledger evidence,
and run_l1_offline.py's rule that a SKIP of a scope-declaring check is the runner's rc 3.
The scope declaration is load-bearing here: touched-requirements.sh keys apps/* to nothing
and platform/monitoring/* to R-OBS-01/02, never R-OBS-04, so a new untested PrometheusRule
would otherwise be gated by nothing.
The check asserts the pins and their lockstep, that the image bakes and records promtool,
that the promtool IN USE reports exactly the pin (a FAILURE, not a skip: the wrong engine
still prints SUCCESS), that exactly ONE harness exists and none fetches an engine, that
every rule-unit test file passes, and — on every run — that the harness CAN fail, by putting
a synthetic rule through it twice with one expectation mutated.
MISSING TESTS ARE A RATCHET, deliberately, and the reasoning is in the check's header. 51 of
58 alert rules have no unit test. Failing on all of them makes the gate red until ~51 tests
exist, so it gets disabled and protects nothing; merely reporting is exactly how the CNPG
tests came to be enforced by nothing. So the gap is DECLARED in the check as a shrink-only
register, printed with counts every run (13 alert files nothing tests at all; 35 named
alerts inside covered files that nothing asserts on), and it cannot grow: a new
PrometheusRule, or a new alert in an already-covered file, FAILS without a test, and a stale
entry FAILS too. A missing test is never an exit-3 skip — SKIPPED is reserved for the one
genuine environment gap, promtool being absent.
PROVEN, in the rebuilt image (promtool 3.14.0):
* both suites pass through the single harness: cnpg 6 rules, monitoring 36 rules, SUCCESS.
* the check passes: 95 assertions, 7/58 alert rules unit-tested, 13 declared gap files.
* NOT VACUOUS, twice over. Shortening CNPGPrimariesCoLocated's `for: 30m` to 5m turns it
red (pending expected at 25m/29m, got firing), reverted. Adding an untested
PrometheusRule (platform/kubevirt/probe-alerts.yaml) turns it red on the ratchet,
removed. The harness's own mutation self-test runs on every invocation.
* the scope mechanism selects it: `run.sh --layer l0 --requirements r-nosuchreq-99
--include-scope whole-repo --print-selection` lists alert-rules-unit-tested.

Every unprefixed './dev.sh run kubectl ...' pointed at the dev cluster,
which was decommissioned on 2026-09-12. The banner cheerfully named dev and
the command then hung or errored against a context that no longer answers,
with nothing saying the cluster is gone. I hit this repeatedly tonight.
CLUSTER=dev is still accepted rather than removed, because the dev VM disks
were deliberately kept so the environment is reversible — but it now warns.

infra/devcontainer/kubeconfig.sh was never staged into the delivery-A commit, so
the branch built on main carried main's single-cluster tooling and `--context
k3s-prod` failed with 'context does not exist' mid-incident. Not Flux-reconciled,
so it never affected the cluster — but it breaks prod diagnosis from a checkout of
this branch, which is when you need it most.
Carries the concurrency fix: the merged kubeconfig holds both contexts and NO
current-context, with each invocation getting a per-invocation selector file
prepended to KUBECONFIG. Two concurrent dev.sh runs with different CLUSTER values
previously overwrote each other's current-context mid-command — reproduced live,
a CLUSTER=dev reader returned k3s-prod nodes on 3 of 7 iterations.

Controller now reaches the kube-API directly through the pfSense NAT
(192.168.2.50:6443 -> kube-vip VIP 192.168.1.49:6443), validating TLS
against the VIP via tls-server-name. Removes the dev.sh SSH-tunnel
scaffolding and updates the ansible source-of-truth so a rebuild
regenerates a direct-access kubeconfig.

Bake the conformance harness toolchain into infra/devcontainer so `make -C ci gate`
runs identically here and in CI:
- Containerfile: install kyverno CLI (1.13.4), kyverno-json, chainsaw (0.2.12),
yamllint (1.35.1), check-jsonschema (0.29.4), yq (4.44.6) via new pinned RUN block;
add diffutils + python3-pip; drop stale LIBVIRT_DEFAULT_URI; refresh header for the
Proxmox(bpg)+conformance toolbox; extend /etc/dev-toolchain-versions provenance.
- versions.env: add KYVERNO/KYVERNO_JSON/CHAINSAW/YAMLLINT/YQ/CHECK_JSONSCHEMA;
align KUBECTL 1.32.0 -> 1.31.4. dev.sh build(): pass the new --build-args.
- ci/versions.env: pin CHECK_JSONSCHEMA_VERSION=0.29.4 (single source of truth).
Fix harness seams so the gate can run:
- dev.sh run(): mount the sibling spec repo (home-network-k3s) read-only at
/home-network-k3s for ci/spec-immutability.sh (R-TEST-06); conditional so the
container still runs without it.
- conformance/lib/common.sh conf_dirs_for_layer(): accept a comma/space list of
layers and union the dirs, so ci/conformance.sh `run.sh --layer l2,l3` selects
both layers in one pass (backward compatible for single layers).
NOTE: ci/versions.env pins KYVERNO_JSON_VERSION=0.0.5, which has no upstream release
(max tag is v0.0.3; platform/kyverno/scripts/run-l0.sh already defaults to v0.0.3).
Baked v0.0.3 and flagged for PM to correct ci/versions.env. kyverno-json is not used
by any static gate stage.

- drop stale libvirt socket mount + LIBVIRT_DEFAULT_URI (old KVM cluster)
- auto-open an SSH tunnel (local :16443 -> primary 127.0.0.1:6443 over the
pfSense SSH NAT) on each run so kubectl/flux/helm reach the cluster with no
manual setup; DEV_NO_TUNNEL=1 opts out, K3S_SSH_* env overrides the NAT front
- refresh header/usage comments (bpg/proxmox, not dmacvicar/libvirt)

- inventory routes SSH via 192.168.2.102:2250/2251/2252; new k3s_node_ip carries
each node's real 192.168.1.x for --node-ip / k3s_api_host / Cilium parity
- dev.sh bind-mounts ~/.config/home-k3s/ansible-vault-pass (ro) so vaulted
playbooks can run in the pinned container (ansible.cfg vault_password_file)

Two dev.sh gaps surfaced while running bootstrap/sops/install-age-key.sh:
- kubectl defaulted to localhost:8080 (connection refused) because KUBECONFIG
was never set in the toolbox. Set KUBECONFIG=/work/infra/ansible/.cache/dev.kubeconfig
(override via DEV_KUBECONFIG); --network host already reaches 10.73.0.11:6443.
- age-keygen.sh writes the PRIVATE key to ~/.config/sops/age/keys.txt, but that
path was not mounted in the --rm container, so the key was lost on exit. Mount
${HOME}/.config/sops -> /root/.config/sops (created first) so the key persists
on the host and SOPS_AGE_KEY_FILE resolves to it.

Per operator rule: OpenTofu/age/sops/flux are Go binaries, so bake the toolchain
into a pinned Fedora-44 dev container (matches host libvirt 12) instead of a venv.
infra/devcontainer/: Containerfile + versions.env (tofu 1.9.0, age 1.2.1, sops
3.9.4, flux 2.4.0, kubectl 1.32.0, helm 3.16.0) + dev.sh (runs with host libvirt
socket + repo + ssh mounted) + README. Built & validated: all tools resolve;
virsh reaches host libvirt from inside the container.
Also record resolved Phase 1 decisions in PHASE1-SCOPE.md (6GiB/4vCPU x3;
k3s-dev NAT 10.73.0.0/24; container toolchain). Gate green.
