jakman85andClaude Opus 5 dc2d1ce17e fix(conformance): the R-NET-04 scan descended into nested agent worktrees
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
TRACKED_YAML rglob'd from the repo root excluding only .git and _artifacts, so it
also walked .claude/worktrees/agent-*/ — the isolated worktrees created for agent
runs. The check counted 5 CiliumEgressGatewayPolicy objects where exactly 1 is
authored, failing R-NET-04 for a reason unrelated to egress steering. Now skips
dot-DIRECTORIES (covering .git, .claude, .cache) while still matching dot-FILES
such as .sops.yaml. .claude/ is gitignored, so nothing beneath it is authored
surface.

jakman85andClaude Opus 5 6a8953e288 feat(prod): observability for the two failure modes that went unseen, plus OIDC self-healing
Minimal prod delivery, authored directly on main (= prod's live revision d1a6628)
rather than by merging work/prod-standup-campaign. That branch carries the DNS apex
inversion, which would have set prod's BASE_DOMAIN to home.keithjackson.dev; prod
runs external-dns with policy: sync and txtOwnerId: prod, so it would have begun
rewriting apex records dev owns while the non-k3s prod still serves 443 there.
Operator sequencing is "dev migrates first". Nothing under clusters/ is touched
here at all, which is what makes this safe to land now.

Also deliberately EXCLUDED, because prod's live cluster-vars has no CNPG_BACKUP_PATH
key and StrictPostBuildSubstitutions would fail the whole tier: the R2 rework of
platform/velero/ and the CNPG destinationPath changes. Those land as
feat/r2-backup-prod together with the endpoint and bucket knobs.

WHAT THIS FIXES

1. Nothing was watching CNPG. All three prod databases have run since bootstrap with
   ContinuousArchiving=False and firstRecoverabilityPoint=null, and no alert existed
   anywhere. Because archive_mode=on and the archive command fails, Postgres refuses
   to recycle WAL: keycloak-db holds every segment ever written (257 MiB on a 5 GiB
   volume, ~6.8 MiB/h) — roughly 29 days to a disk-full PANIC on the cluster's SSO
   database. Found by hand, 38h late. CNPGWALArchiveBacklog would have fired within
   the hour, and evaluates to 3 firing series on prod today.
   Rules key on cnpg_collector_* rather than cnpg_pg_stat_archiver_*, because
   nextcloud-db's exporter cannot log in to its own database (permission denied for
   database "nextcloud", both clusters) so the pg_stat_archiver family does not exist
   for it — the obvious metric would have been blind to one database in three.

2. No PVC outside namespace=monitoring had any fill alert. New rules are partitioned
   by namespace so they cannot double-fire with MonitoringVolumeFillingUp, pinned to
   job="kubelet" (the apiserver copy of the same series reports namespace=default),
   and guarded by inodes > 0 — block-mode PVCs such as unifi-rootdisk report
   available=0 forever and would otherwise have fired critical permanently.

3. VPNTunnelDown could never clear on a cluster with no gateway node; it has been
   firing critical on prod since 2026-09-05. Now guarded so prod self-arms the moment
   a node carries the egress-gateway label, with dev's behaviour unchanged today.

4. The Keycloak realm import fails OPEN: an unresolved placeholder is stored
   LITERALLY and the import still reports success, then sits at Done=True and never
   re-runs. On 2026-09-06 all 12 prod OIDC clients held the literal
   $(env:..._CLIENT_SECRET) string and every SSO login failed, while every signal was
   green. The CronJob is the level-triggered correction; two alerts make its silence
   observable. Repaired live already — this stops it recurring.

Also: the R-NET-04 conformance scan descended into nested agent worktrees under
.claude/, counting 4 egress policies where 1 is authored.

jakman85andClaude Opus 5 8a2be824f6 feat(ci): substitution-safety gate + escape 6 comment hazards; strict mode is now SAFE
Adds conformance/tests/l0-static/flux-postbuild-substitution/ — an offline, stdlib-only
L0 check tagged R-ENV-02 + R-GITOPS-01 (deliberately NOT R-TEST-01, which would
overclaim). It reuses lib/status.py's `resources:` walk rather than forking it, so "what a
path renders" has exactly one definition. It asserts: every ${...} on a substituted path
is defined-or-escaped (comments included); no default-operator form on an undefined name;
no unparseable expansion; the rendering path actually substitutes cluster-vars; every
overlay-patched /data/KEY has a base default; and that the gate itself is load-bearing.

WIRED AS AN UNCONDITIONAL STAGE (3c) in ci/l0.sh, and that matters: stage 3b scopes to
touched requirements, and ci/touched-requirements.sh maps only clusters/* to R-ENV-02 —
so an edit to a substituted manifest under apps/ or platform/ would have filtered this
check out of exactly the change that introduces the bug. l0 fail -> BLOCK=1 in gate.sh.

Mutation-tested all five assertion classes (undefined token, indexed expansion, :- form,
missing substituteFrom, un-wired gate); each fails as intended, baseline green.

STRICT MODE IS PROVEN SAFE TO ENABLE — measured, not inspected. For all 11 substituted
paths, `kubectl kustomize --load-restrictor LoadRestrictionsNone <path> | flux envsubst
--strict` exits 0 against cluster-vars base defaults. Negative control confirms the
incident: with K3S_API_HOST unset, non-strict renders k8sServiceHost empty while strict
exits 1 with `variable not set (strict mode)`. The feature gate itself is NOT flipped
here — that is a live-cluster change and the operator's call.

Escapes the six comment hazards that stood in the way (apps/vms/unifi x4,
platform/longhorn x2). All were prose ABOUT the escaping convention; since the repo's own
contract is that $${...} emits a literal ${...}, escaping them is both precise and
self-consistent. kustomize strips these particular comments today, but comment survival is
an implementation detail — a body comment carrying $ WAS observed surviving into built
apps/wave-1 — and a survivor would kill the whole Kustomization.

DOCTRINE CORRECTED (measured against flux 2.4.0): clusters/base/apps-vms.yaml claimed an
indexed expansion is fatal "escaped or not". Escaping is TOTAL — $${ARR[0]} emits the
literal text safely; only the UNESCAPED indexed form is fatal. Corrected in place.

Also empties DOCUMENTED_GAPS in conformance/run.sh with rationale: R-ENV-02 and
R-GITOPS-01 now have a real verifying test, which run.sh's own comment named as the
trigger for removing them.

Advisory output (not failures): 6 dead cluster-vars knobs — BASE_DOMAIN, CLUSTER_ENV,
CLUSTER_POD_CIDR, PIA_REGION, PLATFORM_NODE_SELECTOR_{KEY,VALUE}. The last four are
documented reference-only; BASE_DOMAIN and CLUSTER_ENV look like genuine rot (hostnames
are hardcoded elsewhere) and are worth a follow-up.

Gate: MERGE GATE: PASS. 102 assertions, 0 hazards.

Serves: R-ENV-02, R-GITOPS-01.

jakman85andClaude Opus 5 6e77150ae1 fix(ci): kill the false-green base resolution; cover R-SEC-01/02 + R-TEST-06 (L0)
Unblocks the enforced Gitea gate, which correctly BLOCKED this branch on
['R-SEC-01','R-SEC-02','R-TEST-06'] being touched but uncovered. Tests were authored;
the coverage rule was NOT narrowed.

=== THE FALSE GREEN (root cause) ===
`make -C ci gate` locally reported PASS having checked NOTHING. resolve_base() validated
nothing, and EVERY way of failing to find a base degraded silently to an empty touched
set + exit 0: an `HEAD~1` last resort, a two-dot diff fallback masking a failing
three-dot diff, and no check that HEAD is even AHEAD of the base. Run while sitting on
`main` (main == origin/main), `origin/main...HEAD` is empty -> "no changed files vs
base" -> the empty set means run.sh is invoked with NO --requirements -> coverage.py's
--require gate never runs at all. Green by vacuum.

Now: candidates are BASE_REF > GITHUB_BASE_REF > origin/main > main, each verified to
resolve. HEAD~1 and the two-dot fallback are gone. Unresolvable base / no merge base /
failed diff / HEAD-not-ahead -> loud banner, EMPTY stdout, exit 3, and a machine-readable
reason (on-base | no-base | diff-failed). gate.sh turns exit 3 into an UNDECIDED
decision: `on-base` -> "NOT APPLICABLE — no branch under gate" (exit 0 so push-to-main
runs don't break, but it never reads as PASS); `no-base`/`diff-failed` -> BLOCKED. It
also now prints the diff base it used. A stale local main warns (widens, never falsely
greens). Also fixed `make -C ci test`, which was SWALLOWING failing suites.

Regression: ci/tests/touched-requirements-base.test.sh — 31 assertions over 8
throwaway-repo scenarios including the exact false-green case, an already-merged branch,
no base ref, a single-commit repo, bogus BASE_REF, a shallow GITHUB_BASE_REF, and
origin/main-preferred-over-stale-main.

=== NEW L0 STATIC LAYER (conformance/tests/l0-static/) ===
Where docs/14 actually puts these invariants. Each check.sh really executes offline via
`run.sh --layer l0` and is wired into ci/l0.sh, so it runs on every PR. No scaffolds.

R-SEC-01 no-plaintext-secrets (165 assertions / 445 tracked files): .sops.yaml holds only
PUBLIC age recipients; every committed Secret is SOPS-wrapped with a mac and ENC[...]
values; ansible vault.yml files are $ANSIBLE_VAULT; no secret-valued ansible key carries
a literal outside a vault; no PEM key / age secret key / kubeconfig client-key-data is
tracked; Flux declares sops decryption; the disallow-plaintext-secrets policy Enforces
and has a proving `result: fail` row. Exemptions are SELF-POLICING, not path allowlists —
a .example must be referenced by no kustomization and hold only placeholders, and the
Kyverno fixture is exempt ONLY while a test asserts the policy rejects it. Proven against
7 injected violations, including deleting the negative row and weakening Enforce->Audit.

R-SEC-02 least-privilege-rbac (41 assertions): no wildcard apiGroup/resource/verb and no
escalate|bind|impersonate in any in-repo Role/ClusterRole; no ServiceAccount bound to
cluster-admin or a wildcard role; the conformance runner's own test identity is scoped
and holds no rights over RBAC objects; the default-deny/host-namespace/egress-class
policies Enforce and each carry a negative row. Proven against 6 injected violations.

R-TEST-06 spec-immutability-enforced (16 assertions): drives the REAL
ci/spec-immutability.sh against HERMETIC throwaway spec repos and asserts its exit code
in every state — clean-at-pin 0, edits under docs/ or decisions/ 1, untracked addition 1,
unadopted drift 1, explicit pin bump 0, ABSENT spec repo 3 (honest skip, never green),
unpinned SPEC_PIN 1 — plus that gate.sh sets BLOCK=1 on its failure, so the mechanism is
load-bearing. The real spec repo is never written to.

Each check documents what it does NOT cover (runtime decryption, git history, runtime
least-privilege, branch protection) rather than overclaiming. status.py now reads
check.sh too, so a placeholder L0 body still outranks an `executable: true` annotation.

Coverage 37/51 -> 40/51 (11 gaps); executable tests 32 -> 35; scaffold-only stays 5 —
no sixth scaffold was added.

Serves: R-SEC-01, R-SEC-02, R-TEST-01..06.
