fix(monitoring): alert when a Velero schedule has NEVER backed up, or is paused
VeleroNoRecentBackup could not fire for the failure mode that actually happened.
`(time() - velero_backup_last_successful_timestamp{schedule!=""}) > 24*3600` is the
right SHAPE — per-schedule, un-aggregated — but Velero only creates that series once
a backup for the schedule SUCCEEDS, and `time() - <absent series>` yields no series.
So it detects "backed up once, then stopped" and is structurally INERT on "never
backed up". Prod ran with `velero-daily` (the schedule carrying VOLUME DATA) paused
and never-successful: no volume backups at all, nothing alerted, and it was masked
because `velero-daily-resources-only` completed cleanly every 03:00, so every other
backup signal read green while only Kubernetes objects were protected.
A PromQL-only fix is impossible, verified rather than assumed: velero v1.18.1 exports
35 velero_* metric names and every one carrying a `schedule` label is created by a
backup ATTEMPT, not by the Schedule object. A throwaway `paused: true` Schedule on
prod produced ZERO velero_* series, and nothing exposes `spec.paused`. The fact is
not in the TSDB, so the Schedule CRs are exported via kube-state-metrics'
custom-resource-state collector — the path this repo already uses for
kube_node_labels — as kube_velero_schedule_{created,paused,protects_volume_data,info}.
Proven by running KSM v2.20.0 with this exact config against prod's API: the CRD
list/watch rule the chart adds is MANDATORY, not cosmetic — without it KSM emits the
CRS metrics as an empty set, silently.
Three rules, all keyed on PROPERTIES rather than schedule names:
* VeleroScheduleNeverBackedUp (critical) — a Schedule older than 36h with no
successful backup ever. The 36h grace comes from creationTimestamp so a newly
added schedule is not paged before its first run is even due.
* VeleroSchedulePaused (warning) — the direct root-cause signal; a paused backup
schedule must never be silently indefinite.
* VeleroNoVolumeDataBackup (critical) — THE ANTI-MASKING RULE. Fires unless some
schedule with spec.template.defaultVolumesToFsBackup=true succeeded in 36h, so a
healthy resources-only schedule can never make the platform look protected.
Reading the property that DEFINES volume protection (not a name list) matches
platform/velero/volume-policies.yaml and survives renames. `or vector(0)` is
load-bearing: `count(<empty>) == 0` returns no series and would be inert —
absence of the exporter is deliberately the alarm.
Adds the repo's first Prometheus rule-unit-test harness (platform/monitoring/tests/,
wired as the `prom-rules` gate stage). It flattens the COMMITTED PrometheusRule CRs —
never a copy — and pins every rule in the group both ways: quiet on today's healthy
prod state, firing on the reconstructed bad state, with `for:` durations asserted.
Two mutation checks confirm the tests are not vacuous: dropping `or vector(0)` and
breaking the `unless on (schedule)` join each turn the suite red. This is the tool
that makes both of this repo's recurring alert bugs — permanently-firing and
structurally inert — provable offline, which neither yamllint, Kyverno, nor a healthy
cluster can do.
Proof of the fix is by construction; the live metrics cannot show it any more, because
`velero-daily` was unpaused on 2026-09-12 and has since completed 2492/2492 items.
The throwaway probe Schedule and the probe KSM deployment were deleted and the
deletion confirmed; `velero-daily` remains unpaused.

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.

fix(apps): reconcile goldens to one canonical render + enforce render==golden gate
The committed apps/ goldens were a MIX of two render flag sets: 8 services were rendered with `--no-image-automation` (no image CRs) while gitea and nextcloud carried stale ImageRepository/ImagePolicy CRs from a render WITHOUT the flag. Neither single command reproduced all goldens, and the gate did not catch it. Part A — canonical render: python3 catalog/render.py --all catalog -o apps --wave-layout --no-image-automation `--no-image-automation` is canonical: image automation is authored-but-DISABLED (DECISIONS-LOG; image-reflector/-automation controllers not installed), and every app was onboarded via this flag. Re-render drops the ImageRepository + ImagePolicy objects from gitea + nextcloud only (52 line deletions, purely the trailing image-automation blocks). No functional content changed — the nextcloud postStart hardening and gitea OIDC hook are untouched. Part B — enforcement: ci/render-golden.sh renders every onboarded catalog service with the canonical command into a temp dir and FAILS on ANY diff vs committed apps/ (missing golden or content drift), across all 10 services (not just the 3 L1 spot-checks). Not-onboarded catalog entries (keycloak, vm-demo) are excluded per DESIGN-waves. Wired as a required no-cluster stage in ci/gate.sh, ci/Makefile, and both the live (.gitea/workflows/gate.yml) and dormant (merge-gate.yaml) pipelines. Proof: tampering a golden makes the stage exit 1 (blocks merge); reverting restores exit 0. `make -C ci gate` green in the devcontainer. Co-Authored-By: Claude Opus 4.8 <[email protected]> |

Phase 0 clarification follow-ups + reconcile CI integration seams
Adopt the spec's Phase-0 clarifications (spec now at pin a7fc19f) into the impl: - schema v1.1: enforce exposure:public => auth.mode!=none (positive+negative tested). - Kyverno: add longhorn=>size and longhorn=>NOT-reacquirable invariants (R-STATE-02/03). - Ratify the homelab.keithjackson.dev/* label-key convention (now in spec docs/03). - R-TEST-06 spec-immutability gate: ci/SPEC_PIN + ci/spec-immutability.sh + gate.sh stage + Makefile target + a Gitea job (checks spec repo clean & at pin). - touched-requirements.sh: conformance tags are the authoritative source. Reconcile 3 CI seams the CI worker flagged (gate was RED, now GREEN): - create schemas/validate.sh (SCHEMA_VALIDATE_CMD entrypoint) — L0 schema gate runs. - fix l1.sh/conformance.sh to run.sh's real interface (fixed _artifacts/ paths; no --junit/--coverage) and collect artifacts. - exec bits on new scripts. make -C ci gate => PASS (l0 skips locally w/o kyverno binary; green in CI).
