jakman85 d616fd4025 merge: promtool is in the toolchain, so the alert unit tests actually run
324 lines of mutation-checked promtool tests had landed with nothing to
execute them: promtool was not in the pinned toolchain, so the coverage was
present and enforced by nothing — the failure mode this repo keeps hitting.

promtool 3.14.0 is now pinned in both versions.env files (matching prod's
Prometheus, verified against the running image) and baked into the
container. The two competing harnesses are consolidated into one, and the
two competing wirings into one: the bespoke ci/prom-rules.sh stage is
deleted in favour of a scope-declaring conformance test, because a
hand-written stage running one hardcoded script is exactly the pattern
b9f8807 just removed. Missing promtool is exit 3 — UNWIRED, never green.

51 of 58 alert rules still have no unit test; that gap is a shrink-only
ratchet that fails if it grows, rather than a blanket FAIL that would get
disabled or a report nobody reads.

jakman85andClaude Opus 5 78d0f1b0f6 feat(ci): promtool in the pinned toolchain, one alert-rule harness, and the gaps declared
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.

jakman85 55b90849d1 merge: the arrs had no download client at all, and now agree on paths
Investigating the path disagreement found the larger defect: sonarr and
radarr each returned [] from /api/v3/downloadclient — Completed Download
Handling had never been wired up, not merely broken. Both now have
qBittorrent configured plus a remote path mapping /downloads/ ->
/media/downloads/, proven with a real completed torrent and a negative
control: same torrent, same client, mapping absent gave an unresolvable
/downloads/... and mapping present resolved the real file at inode 36144.

This state lives in each arr's database, NOT in git — a rebuild from git
does not restore it. Recorded in DECISIONS-LOG with the recommendation to
close it properly via path agreement instead.
2026-09-13 00:01:55 -05:00
jakman85andClaude Opus 5 2f38b8156b fix(arr): wire qBittorrent as a download client + Remote Path Mappings
qBittorrent reports finished releases at /downloads/<name>; sonarr and radarr
see the same inodes at /media/downloads/<name>, so Completed Download Handling
could never resolve what the client handed it. Configured, on prod, via each
app's own HTTP API:

  * download client qBittorrent -> qbittorrent.qbittorrent.svc.cluster.local:8080
    (it did not exist in EITHER arr: both /api/v3/downloadclient returned [])
  * Remote Path Mapping /downloads/ -> /media/downloads/ for that host

Both built from each app's /downloadclient/schema, matched on identity before
writing, and re-running creates nothing. downloadclient/testall reports
isValid=true in both. Proven with a negative control: Sonarr's queue showed
outputPath=/downloads/... with the mapping deleted and /media/downloads/...
with it present, for the same completed torrent.

This state lives in sonarr.db / radarr.db on the config PVCs, NOT in git — a
rebuild from git alone does not restore it. Recorded as a wart, with path
agreement (repointing SavePath to /media/downloads) recommended as the durable
fix and put to the operator rather than taken unilaterally.

jakman85 4865734c5f merge: alert when a backup schedule has NEVER run, and when one is paused
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
VeleroNoRecentBackup could not see the failure that actually happened:
velero-daily sat paused having never produced a successful backup, so
velero_backup_last_successful_timestamp{schedule=...} did not exist and
time() - <absent series> yields no series. Prod had no volume backups and
nothing alerted, further masked by a resources-only schedule succeeding
daily. No velero_* metric describes a Schedule OBJECT, proven by scraping a
throwaway paused Schedule and finding zero lines, so this exposes the CRs
via kube-state-metrics customresource_state and keys on
defaultVolumesToFsBackup — the property, not a name list. Adds the repo's
first prometheus rule-unit-test harness, mutation-checked both ways.

jakman85 b9f8807aa6 merge: whole-repo L0 invariants are DECLARED, not hand-wired per test
The gate had been accreting one bespoke UNCONDITIONAL stage per whole-repo
L0 test (3c/3d/3e), each repeating the same ~12-line rationale and each one
something the next author had to remember to write. Forget it and the test
runs only when some unrelated requirement happens to be touched.

Tests now declare conformance.home.k3s/scope: whole-repo and run.sh unions
them in via --include-scope; the three stages are deleted. 10 of 13 tests
are whole-repo, 3 stay path-scoped with the path map widened instead
(infra/* -> R-ENV-01, ci/* -> R-TEST-06). A new meta-test makes the bespoke
pattern fail the gate if it creeps back, and a change under
conformance/tests/<test>/ now attributes that test's own requirements, so
weakening a test is gated by what it certifies.

rc-3 (SKIPPED is UNWIRED, not green) is preserved and demonstrated; the
incident narratives moved into the tests they describe rather than being
deleted. Gate cost for a scoped change rises 20.7s -> 41.8s, a ceiling any
empty-touched-set change already paid.

jakman85andClaude Opus 5 7057bbb711 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.

jakman85andClaude Opus 5 5fa278f61c fix(ci): declare whole-repo scope instead of hand-writing a gate stage per invariant
R-TEST-03 runs the conformance subset a change TOUCHES. That has one blind spot, and it
is the worst-shaped kind: an invariant that quantifies over the whole tracked tree — or
over subtrees ci/touched-requirements.sh's coarse path map keys to NOTHING (apps/, infra/,
most of platform/) — cannot be selected BY the requirements a change touches, because the
change most likely to break it attributes no requirement at all. Requirement-scoped
selection then filters the check out of exactly that change.

The repo's answer had been a hand-written "UNCONDITIONAL" stage per such check in
ci/l0.sh: 3c flux-postbuild-substitution, 3d keycloak-client-secret-reconciler, 3e
bulk-tier-distinct-from-replicated. Three near-identical 12-line rationales, three
hardcoded check.sh paths, three copies of the same rc 0/3/* case block — and worst, a
mechanism that failed SILENTLY, because whoever added the NEXT whole-repo invariant had
to REMEMBER to write a stage, and if they forgot the check ran only when some unrelated
requirement happened to be touched.

A test now DECLARES the scope of its invariant and the runner enforces it:

    metadata:
      annotations:
        conformance.home.k3s/scope: "whole-repo"

* conformance/lib/common.sh  conf_dirs_for_scope(s) resolves the annotation. Carries the
                             general rationale, once, instead of per stage.
* conformance/run.sh         --include-scope SCOPE unions declaring tests into select_dirs,
                             still bounded by --layer. New --print-selection resolves the
                             selection and exits, running nothing.
* lib/run_l1_offline.py      --unwired-scope: a SKIP of a declaring test exits 3, not 0.
                             --summary-out: one step-summary line per executed check.
* ci/l0.sh                   Stage 3b gains --include-scope whole-repo and an rc-3 arm.
                             Stages 3c/3d/3e DELETED (-150 lines).
* ci/l1.sh, ci/conformance.sh  pass --include-scope too, so the next whole-repo invariant
                             at ANY layer needs only the annotation.

rc 3 SEMANTICS PRESERVED EXACTLY. A whole-repo check reporting "nothing to audit" is
reporting that the tree it audits has VANISHED. The deleted stages called that "not a
pass" and set the gate's rc=3; the runner now returns 3 and ci/l0.sh maps it to rc=3.
A missing check file still degrades to not-green, never to silence.

THE REASONING WAS RELOCATED, NOT DELETED. Each stage's incident narrative moved into the
header of the test it describes, beside its scope annotation: the Cilium k8sServiceHost
empty-substitution CNI outage (2026-09-01), 12 unusable Keycloak clients behind a green
cluster (2026-09-06), and a multi-TB bulk volume landing on the 3-replica tier.

AUDITED ALL 13 EXISTING l0-static TESTS, individually. 10 declare whole-repo scope; 3 are
DELIBERATELY left requirement-scoped and say so in their own headers:
  * placeholder-guard-coupling — inputs are bootstrap/ + clusters/, both already mapped to
    a requirement it declares. Scoping cannot hide a breaking change.
  * dev-nodes-provisioned-as-code — inputs are infra/ and nothing else.
  * spec-immutability-enforced — inputs are ci/ and the read-only spec repo.
The latter two were nonetheless under-gated because the PATH MAP was incomplete, which is
the right place to fix a path-scoped invariant: infra/* -> R-ENV-01 added, and R-TEST-06
added to .gitea/*|ci/* (it is no longer an uncovered ID — spec-immutability-enforced
carries the label, so attributing it no longer false-blocks the coverage gate).

NEW conformance/tests/l0-static/whole-repo-invariants-wired (R-TEST-03) keeps the
declarative mechanism honest for ALL declaring tests at once, replacing the three tests'
individual "ci/l0.sh greps my own check.sh path" self-assertions. It proves the union
EMPIRICALLY: with a requirement filter matching no test the L0 selection is empty, and
with --include-scope it is every declaring test; a scope-declared synthetic SKIP exits 3
while an undeclared one exits 0; and a ci/*.sh that hardcodes a check.sh path must belong
to a test that also declares the scope, so the bespoke pattern cannot creep back.

TASK 2 — a changed test attributes the requirements it CERTIFIES.
ci/touched-requirements.sh gains detection rule 3: a change anywhere under
conformance/tests/<test>/ attributes that test's own conformance.home.k3s/R-* labels, read
from its chainsaw-test.yaml. The content scan could not close this — it reads only
added/removed lines, so it sees a change to the LABEL BLOCK but not to the test BODY,
which is exactly the case that matters. Labels are read from HEAD or, failing that, from
the BASE, so DELETING a test still attributes what it used to certify; otherwise removing
the only verifier of a requirement is the cheapest way to make the gate stop checking it.
Whole-line `#` comments are dropped first and *.md is untouched, honouring the existing
"reference, not declaration" rules.

Both changes are fail-closed: every one of them can only ADD tests or requirements to a
run, never remove one.

TESTS: new ci/tests/touched-requirements-test-attribution.test.sh (15 assertions) covers
rule 3 — body-only edit, nested-fixture walk-up, test deletion, header-comment R-IDs not
attributed, non-test paths unaffected, and both new path-map entries. The two existing
suites still pass (39 assertions). `make -C ci test` runs all three.

jakman85 78d76fa089 merge: qBittorrent can finally write where the arrs can see it
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
qBittorrent's SavePath was /downloads and no such directory existed in the
container, so the download client had no working destination and nothing
downstream could see its output. It now mounts the same NFS export the arrs
use, narrowed to the downloads subtree via subPath — one mount, so the
EXDEV hardlink trap the bulk-tier test guards stays closed. PUID/PGID are
load-bearing: the export is owned 1000:1000 and the image's default 911 is
denied.

jakman85 9e7d919d12 merge: CNPG primaries spread one per node, and the condition is now reported
All three primaries had re-concentrated onto prod-1 (the node with known
etcd/Longhorn I/O contention), so losing it meant three simultaneous
failovers. Two switchovers rebalanced them; semaphore-db deliberately stays
on prod-1 as the lightest writer, saving a third write interruption.

CNPG offers no role-aware scheduling — targetPrimary exists only under
status — so the placement is CURRENT, NOT DURABLE: the next failover or
rolling update can re-concentrate it. What is durable is CNPGPrimariesCoLocated,
which reports the condition instead of leaving it to be found by hand.

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.

jakman85andClaude Opus 5 78bc53afc7 feat(qbittorrent): attach the downloads area of the bulk export — the chain was broken end to end
qBittorrent was the one member of the download chain with NO media volume.
Its live config said

    Session\DefaultSavePath=/downloads/
    Session\TempPath=/downloads/incomplete/
    Downloads\SavePath=/downloads/

while `ls /downloads` in the container returned "No such file or directory".
The catalog entry declared exactly one volume — config at /config on longhorn —
and carried a comment deferring the downloads volume "until OQ-2 is resolved".
OQ-2 WAS resolved (schema 1.5.0 static bulk NFS PVs); plex, sonarr, radarr and
nextcloud all took their mounts and qBittorrent's was simply never added. So the
download client was writing, or failing to write, a path that did not exist —
and anything it did create would have been invisible to sonarr/radarr, lost on
every pod recreation, and consuming the node's ephemeral disk until then.

WHAT THIS ADDS to catalog/qbittorrent.yaml (rendered into apps/wave-0):

  * storage[downloads]: class bulk, export /mnt/Storage/plex, subPath downloads,
    mountPath /downloads, 9Ti advisory. ONE mount of the SAME export sonarr,
    radarr (rw) and plex (ro) already consume, narrowed to the handoff subtree.
  * env PUID=1000 / PGID=3000. LOAD-BEARING, not cosmetic: the container ran as
    uid 911 and /mnt/Storage/plex/downloads is 0755 owned 1000:1000, so the
    export would have mounted cleanly and then failed every write with EACCES.
    Measured both ways on prod: a write as uid 1000 succeeded, the same write as
    uid 911 was denied.
  * podSecurityContext.fsGroup 3000, for the LONGHORN config PVC only, exactly as
    sonarr/radarr set it — fsGroup is a no-op on an in-tree NFS volume.

WHY subPath AND NOT THE EXPORT ROOT AT /media (sonarr/radarr's shape): a download
client has no business writing the library. The arrs need the root mount because
THEY hardlink downloads/ -> tv/|movies/ and link() is a same-MOUNT operation;
qBittorrent performs no such link, so narrowing to downloads/ removes movies/,
tv/ and photos/ from its mount namespace without removing any operation it
performs. It is still ONE mount of the export, so the L0 assertion that no
workload mounts one export twice (the EXDEV trap) holds — and the arrs' own
link() stays intra-mount. Proven live: nlink 1 -> 2, same inode, no EXDEV, every
step executed as uid 1000.

NETWORK: nothing to grant and nothing to steer. An NFS PersistentVolume is
mounted by the NODE KERNEL in the host netns — the established socket to
192.168.2.102:2049 is on the node's own LAN address, the pod netns has no socket
to 2049 at all, and no CiliumNetworkPolicy on this cluster names that host or
port. `ip route get 192.168.2.102` picks eno1 even on the tunnel-owning node, and
Cilium's own egress map lists 192.168.0.0/16 as an Excluded CIDR for every
vpn-class pod while 0.0.0.0/0 goes to the gateway. Public egress still exits the
PIA address; the VPN guarantee is untouched.

NOT CLOSED BY THIS COMMIT, deliberately: absolute paths still differ between this
pod (/downloads/x) and the arrs (/media/downloads/x), so Completed Download
Handling needs one Remote Path Mapping per arr. That lives in the arrs' own
databases, not in git.

jakman85andClaude Opus 5 505083fded feat(cnpg): alert when >1 CNPG primary shares a node — the drift CNPG cannot prevent
`instances: 3` + `podAntiAffinityType: required` fixed the INSTANCE spread but moved
the PRIMARY concentration from k3s-prod-2 to k3s-prod-1: all three primaries
(keycloak-db-2, nextcloud-db-2, semaphore-db-2) ended up on one node, so losing it
meant three simultaneous failovers.

There is NO declarative fix, established from the CRD installed on prod (CNPG 1.30.0,
clusters.postgresql.cnpg.io/v1) rather than from memory. Every spec.affinity field and
spec.topologySpreadConstraints applies to "all the cluster's pods" and is not role-aware;
spec.replica.primary names a Cluster object in a distributed topology, not a node;
primaryUpdateMethod/switchoverDelay/primaryLease govern how a promotion happens, never
where. `targetPrimary` exists only under STATUS, never spec — so `cnpg promote` is an
imperative status patch by construction and there is nothing to put in git. The obvious
workaround is worse than nothing: pod anti-affinity is only ever
...IgnoredDuringExecution while CNPG promotes by relabelling a RUNNING pod, and with
3 instances on 3 nodes it would leave the third instance unschedulable.

So this commits the part that IS durable — visibility — and rebalances live.

CNPGPrimariesCoLocated joins CNPG's own answer to "who is primary" (the <cluster>-rw
Service selects only the primary) against the node: kube_endpointslice_endpoints carries
endpoint_nodename + targetref_name, which two label_replaces lift into node/pod. Neither
family works alone — cnpg_* metrics have no node label, and kube_pod_labels is EMPTY here
(no kube-state-metrics label allowlist), so cnpg.io/instanceRole is not in Prometheus at
all. `* on (namespace, pod) group_left () cnpg_collector_up` keeps an unrelated `*-rw`
Service from triggering it, and uses the one metric present for EVERY instance rather than
the cnpg_pg_stat_* family that is missing for nextcloud-db.

A Ready-node gate stops this becoming another permanently-firing alert: with three
clusters on three nodes a node loss NECESSARILY co-locates two primaries, so the rule
only speaks when the spread is actually achievable, and re-arms when the node returns.

Proven both ways. Live: the expr returned {node="k3s-prod-1"} => 3 before, empty after,
with the inner join still resolving all three primaries (quiet because false, not blind);
loaded into prod's Prometheus as a throwaway `for: 1m` twin it went pending at +70s and
firing at +130s. alerts.promtool-test.yaml pins four cases under promtool 3.14.0 (the
exact version prod runs) and is mutation-checked — dropping the join, dropping the gate
or shortening `for:` each makes a test FAIL.

Rebalanced live, one cluster at a time: keycloak-db -> k3s-prod-2, nextcloud-db ->
k3s-prod-3, semaphore-db deliberately LEFT on k3s-prod-1 (lightest writer, and that node
has the known etcd/Longhorn I/O contention) — two switchovers, not three. Write outage
measured with a `select txid_current()` probe, not estimated: 9.4s and 9.43s, one
contiguous burst each. All three back to readyInstances: 3 with
synchronous_standby_names = ANY 1 (...) and both standbys streaming/quorum.

The placement is CURRENT, NOT DURABLE, and the alert is the point: the next failover or
rolling update can re-concentrate the primaries, and now that gets reported instead of
discovered by hand.

jakman85 df77affc23 merge: the nextcloud database has never been monitored
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
cnpg_metrics_exporter lacked CONNECT on the nextcloud database: an
out-of-band REVOKE materialized its datacl and dropped PUBLIC's implicit
CONNECT, which keycloak and semaphore still inherit. CNPG's API cannot
express a database-level grant, so this follows the repo's existing
level-triggered CronJob reconciler pattern rather than a one-shot Job that
a rebuild would silently skip. CONNECT only; pg_monitor already carries the
read access.

CNPGNoRecentBaseBackup's own remediation hint said `kubectl get backup`.
On this cluster longhorn.io, postgresql.cnpg.io and velero.io each register
kind Backup, so the bare short name resolves to Longhorn's empty set and
prints 'No resources found' while CNPG backups exist. An on-call following
the alert that fires BECAUSE backups look stale would have been told, with
authority, that no backups exist at all — and might re-bootstrap a database
over good ones. Fully qualify it.

jakman85andClaude Opus 5 7880d84bce fix(cnpg): grant cnpg_metrics_exporter CONNECT on the nextcloud database
The CNPG metrics exporter could not CONNECT to the `nextcloud` application
database, so every user-defined collector query against that target failed on
all three instances:

  FATAL: permission denied for database "nextcloud" (SQLSTATE 42501)
  DETAIL: User does not have CONNECT privilege.

The whole cnpg_pg_stat_* / pg_settings / pg_postmaster family was therefore
MISSING for nextcloud-db while the scrape target still reported up=1 — the blind
spot platform/cnpg/alerts.yaml's CNPGMetricsCollectorErroring was written to
catch. It had been firing on all three pods; measured before this change,
cnpg_pg_settings_setting had 765 series for keycloak, 765 for semaphore-db and
ZERO for nextcloud-db. Nextcloud's database had never been monitored.

Root cause is the live ACL, not the spec — all three Cluster specs bootstrap
identically:

  nextcloud : datacl = {nextcloud=CTc/nextcloud}   <- explicit, no PUBLIC entry
  keycloak  : datacl = NULL
  semaphore : datacl = NULL

A NULL datacl means PostgreSQL's defaults, which include CONNECT for PUBLIC, so
keycloak and semaphore admit the exporter only by inheriting PUBLIC's implicit
CONNECT. On `nextcloud` something ran the equivalent of REVOKE ALL ON DATABASE
nextcloud FROM PUBLIC, which materialises datacl and drops that implicit entry.
That REVOKE is in neither this repo nor DECISIONS-LOG.md — it was applied out of
band, which is why the remedy has to be declarative rather than another hand-run
psql.

CNPG 1.30.0 cannot express a database-level GRANT (verified against the live
CRDs): `Database` has no ACL field (`allowConnections` is the datallowconn flag,
not a per-role grant), and managed.roles/DatabaseRole cover role attributes plus
`inRoles` membership only — and membership would hand the exporter the owner's
CREATE/TEMP and all table access to buy one CONNECT. postInitApplicationSQL runs
once at bootstrap, so it cannot repair the already-bootstrapped instances that
are actually broken. So this follows the pattern the repo already uses for state
Flux cannot reach: the level-triggered CronJob reconciler alongside
platform/keycloak/client-secret-reconciler.yaml. A one-shot Job is deliberately
avoided — a completed Job never re-runs, so a rebuild or PITR restore would
silently reopen the blind spot.

Exactly one privilege, and nothing else:

  GRANT CONNECT ON DATABASE nextcloud TO cnpg_metrics_exporter;

giving `cnpg_metrics_exporter=c/nextcloud` — CONNECT only, no CREATE, no
TEMPORARY, no ownership, no superuser, no table or schema grants. Nothing more is
needed because CNPG already creates the role as a member of the built-in
pg_monitor role (verified on all three clusters), which carries the read access
the collector's pg_catalog queries want. It runs as the database OWNER, not a
superuser: enableSuperuserAccess stays off, and a database owner holds the grant
option on its own database.

Verified live on prod:
  * the grant issued under SET ROLE nextcloud, proving no superuser is needed;
  * permission-denied and "Error collecting user query" both went to 0 on
    nextcloud-db-1/-2/-3, i.e. every collector query now succeeds;
  * cnpg_pg_settings_setting now 765 series for nextcloud-db, matching the other
    two, and cnpg_pg_postmaster_start_time present on all three instances;
  * cnpg_last_error = 0 on all NINE instances, so keycloak-db and semaphore-db
    are unaffected and their datacl is still NULL;
  * convergence proven by revoking the grant again and letting the committed
    CronJob restore it, then re-running it against a converged database to show
    idempotence;
  * CNPGMetricsCollectorErroring, firing on all three pods beforehand, has
    cleared (`for: 6h` delays firing, not resolution).

jakman85andClaude Opus 5 21491f901b fix(cnpg): scope DR alerts to the CLUSTER, not the pod — stop a permanent false positive
CNPGNoRecoverabilityPoint has been firing continuously on prod against six
pods — keycloak-db-1/-3, nextcloud-db-1/-3, semaphore-db-1/-3 — i.e. exactly
the REPLICAS of all three Clusters, while the databases themselves are fine:
every Cluster reports firstRecoverabilityPoint=2026-09-07T07:0x, a
lastSuccessfulBackup within the last few hours, ContinuousArchiving=True and
LastBackupSucceeded=True.

Root cause is aggregation scope, not archiving. `cnpg_collector_first_recoverability_point`
reads the backup CATALOGUE, which only the primary owns; a replica reports a
hard 0 for as long as it is a replica. The metric carries no cnpg.io/cluster
label (its label set on prod is container/endpoint/instance/job/namespace/pod),
so `max by (namespace, pod)` evaluated each replica as its own subject and an
`== 0` comparison then held forever. The rule went from correct to permanently
wrong the moment the Clusters went to `instances: 3`; nothing about the
expression changed.

WHY THIS IS WORSE THAN HAVING NO ALERT. An alert that is always firing has
zero information content: its value is identical in the healthy state and in
the failure state, so it cannot distinguish them. It is worse than silence in
two specific ways. First, it trains the operator to delete the notification on
sight, so the day a base backup genuinely stops the seventh identical email is
discarded with the other six — the alert actively MASKS the failure it was
written to catch, which for a DR alarm means discovering the loss at restore
time. Second, it is indistinguishable from a broken alert, so nobody can tell
whether the absence of new alerts means health or means the rule rotted. This
file exists because a real 38-hour archiving failure told nobody; a rule that
cries wolf about six healthy replicas rebuilds exactly the blindness it was
supposed to remove. This repo has been here before — see the permanently-firing
critical VPNTunnelDown post-mortem in platform/monitoring/alerts.yaml.

Fix: group by (namespace, job) and aggregate `pod` away. The CNPG operator
creates one PodMonitor per Cluster, named after the Cluster, in the Cluster's
namespace, so prometheus-operator derives job="<namespace>/<cluster>" —
keycloak/keycloak-db, nextcloud-db/nextcloud-db, semaphore-db/semaphore-db —
which identifies the CNPG Cluster uniquely. `job` rather than bare `namespace`
deliberately: namespace alone works today (one Cluster per namespace, verified
live) but would let two Clusters in one namespace mask each other, since the
healthy one's non-zero value would satisfy `max` for both. The alert now
states what its summary always claimed — this CLUSTER has no recoverability
point — and fires only when no instance of that Cluster reports one.

Proven live against prod Prometheus, read-only (promtool query instant):
  OLD  max by (namespace, pod) (...) == 0  -> 6 series, and 6 ALERTS firing
  NEW  max by (namespace, job) (...) == 0  -> empty
The new expression is not vacuous: forcing the metric to 0 for one cluster's
primary only yields exactly one series, {job="keycloak/keycloak-db"}, so a
genuine single-cluster loss of DR still alerts, per cluster. `promtool check
rules` passes on all 5 rules.

CNPGNoRecentBaseBackup carried the same defect and is fixed the same way.
`cnpg_collector_last_available_backup_timestamp` is also primary-only: on prod
the primaries read 3.1h/2.1h/0.1h old while all six replicas read 0, i.e.
time()-0 = ~56.7 YEARS. It was not firing only because the `> 0` guard was
load-bearing — a single clause was all that stood between this rule and six
more permanent false positives, too thin a margin for a DR alarm. Aggregating
`pod` away removes the dependence: `max` takes the primary's timestamp as the
cluster's answer, and the guard now means "this cluster has had at least one
backup". Verdict unchanged live (old empty, new empty).

The other three rules were audited and deliberately left on `by (namespace, pod)`:
  * CNPGWALArchiveBacklog — every instance reports archive_status and the shape
    is `> 0`, so a replica at 0 never fires and no pod can mask another; `pod`
    names the instance whose archiver is stuck.
  * CNPGWALVolumeNotRecycling — per-pod is REQUIRED, not merely safe:
    aggregating it away would compare one instance's WAL count against
    another's max_wal_size.
  * CNPGMetricsCollectorErroring — unchanged in meaning AND grouping. Its
    grouping is already correct: cnpg_last_error is genuinely per-instance, and
    prod proves it discriminates rather than tracking role — all three
    nextcloud-db pods report 1 while all six keycloak/semaphore pods report 0.
    It is a true positive (the nextcloud 42501 CONNECT grant) owned by separate
    work; nothing here silences or rescopes it.

The general rule, recorded in the file: `== 0`/staleness shapes must aggregate
`pod` away or every structurally-silent pod fires forever; `> 0` shapes are
safe per-pod and keep the instance name.

jakman85andClaude Opus 5 d617983e83 feat(gitea): render gitea-allow-flux-ingress — prod's GitOps source, in git at last
The CNP that lets flux-system's source-controller clone from the in-cluster Gitea
Service was APPLIED LIVE on prod on 2026-09-13 and existed nowhere in this repo. It
carried a provenance annotation saying so. Until now it could not be authored: the
gitea CNPs are GENERATED from the catalog entry, and the contract had no field for
"also admit this in-cluster client" (fixed in the previous commit).

Why it matters more than a missing allow normally would. prod's GitRepository points
at the Service, not a public name (clusters/prod/kustomization.yaml:
`url: http://gitea.gitea.svc.cluster.local:3000/Home-Network/home-network-k3s-impl.git`),
deliberately, so prod's GitOps depends on neither public DNS, Cloudflare, prod's own
Gateway nor ${BASE_DOMAIN}. But gitea-allow-gateway-ingress admits only
`fromEntities: [ingress]`, so source-controller's clone was dropped — and the
HTTPRoute that would have served the post-apex-flip public name instead lives in a
DOWNSTREAM tier that cannot apply while the source is down. Source down -> routes
never rename -> source stays down. Every `kubectl delete cnp` and every cluster
rebuild re-armed that deadlock, and it would have been extremely hard to diagnose
cold.

The rendered object is EQUIVALENT to the live one — same apiVersion/kind, same
name/namespace/labels, and a byte-identical spec (endpointSelector
app.kubernetes.io/name=gitea; fromEndpoints matchLabels
k8s:io.kubernetes.pod.namespace=flux-system; toPorts 3000/TCP), verified against
`kubectl --context k3s-prod -n gitea get cnp gitea-allow-flux-ingress -o json`. The
name matches, so Flux ADOPTS the live object in place: no spec change, so no policy
recompute and no flap on prod's own source. The only difference is that the rendered
object carries no `homelab.keithjackson.dev/provenance` annotation — the reasoning now
lives where the object is authored, in catalog/gitea.yaml, next to the field that
generates it.

Golden re-rendered with the canonical command; the whole apps/ diff is the one new
document.

jakman85andClaude Opus 5 1f20506829 feat(renderer): inClusterClients — authorable direct east-west ingress (schema 1.5.0)
A platform controller that dials a service's ClusterIP directly had NO authorable
form in the ServiceDefinition contract:

  * ingressRoutes renders the north-south allow only — gateway-ingress admits
    `fromEntities: [ingress]`, the Gateway's Envoy identity, and nothing else;
  * dependencies compiles edges only BETWEEN CATALOG SERVICES, from the source
    entry's own declaration.

Under the default-deny baseline (R-NET-01) such a client is therefore DROPPED, and
the only way to unblock it was a live `kubectl apply` of a hand-written CNP — a
cluster object outside git, one `kubectl delete` or one rebuild from coming back.

`inClusterClients: [{namespace, port, protocol?, name?}]` closes that. Each entry
renders ONE least-privilege ingress CiliumNetworkPolicy: this service's
endpointSelector, `fromEndpoints` matching ONLY `k8s:io.kubernetes.pod.namespace`,
`toPorts` carrying ONLY the declared port/protocol — never `fromEntities: all`.
Additive: the namespace default-deny keeps denying everything undeclared (R-NET-02),
and the entry is NOT a dependency edge, so it creates no wave ordering.

Shape notes:
  * selected by NAMESPACE, not pod labels: an upstream controller's labels belong to
    its chart, not to this platform's contract. The cost is explicit — every pod in
    that namespace is admitted on that port, so the field is for platform-controller
    namespaces (flux-system, monitoring), never a shared one. The schema description
    says so.
  * optional `name` (default: the namespace) only names the rendered policy,
    `<service>-allow-<name>-ingress`. That name is operator-facing (kubectl get cnp,
    a Hubble drop), and pinning it lets an allowance that already had to be applied
    live be authored under its EXISTING name, so Flux adopts the live object in place
    instead of creating a near-duplicate and leaving the original unmanaged.
  * one field, not a policy DSL: no arbitrary selectors, entities or CIDRs.

Covered by render.py --selftest (4c): name/namespace/selector/port shape, no
fromEntities widening, default-deny still `ingress: []`, the gateway allow not
displaced, `name` defaulting to the namespace, and nothing rendered when the field is
absent. No golden changes here — no catalog entry uses the field yet.

jakman85andClaude Opus 5 f252ecec25 fix(gitops): prod's source is the in-cluster Service, not a public name
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
The apex flip deadlocked prod's GitOps and this is the durable fix.

The GitRepository pointed at a public hostname. The flip renamed prod's HTTPRoute
hostnames, so that name stopped serving — but the HTTPRoute that would serve the new
name lives in a DOWNSTREAM tier which cannot reconcile while the source is broken.
Source down -> routes never rename -> source stays down. Observed live: srcReady=False,
"unable to list remote for https://gitea.home.keithjackson.dev".

Pointing at gitea.gitea.svc.cluster.local:3000 removes the cycle permanently: prod's
GitOps no longer depends on public DNS, Cloudflare, its own Gateway, or ${BASE_DOMAIN}.
No future domain change can sever prod from its own source.

Plain http is deliberate: cluster-internal traffic to a ClusterIP, TLS terminates at
the Gateway for external clients, the GitRepository has no secretRef (anonymous clone),
and all secrets are SOPS-encrypted at rest regardless of transport.

jakman85andClaude Opus 5 ae37e27f14 fix(gitops): move prod's own Git source with the apex flip
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
The GitRepository url is a hardcoded literal, not templated on ${BASE_DOMAIN}, so
the apex flip did not carry it. But the flip renames prod's HTTPRoute hostnames, so
external-dns (policy=sync) deletes gitea.prod.home.keithjackson.dev and CoreDNS's
split-horizon zone moves from prod.home. to home. — which would have severed prod
from its OWN GitOps source moments after the flip reconciled.

Landed in the same push as the flip deliberately: prod has not yet fetched 9161cab
(still on b9c0970, all hostnames still prod.home.), so both commits arrive in one
fetch and the url changes in the same apply that renames the routes. A live patch
would not survive — the root Kustomization renders this very file and reverts it.

jakman85andClaude Opus 5 9161cab9cd feat(dns): prod takes the apex — home.keithjackson.dev
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
Dev is decommissioned and has released the name. Prerequisites completed and
verified BEFORE this flip:

  1. dev's 18 A records released by its own external-dns (policy=sync; sources
     deleted after suspending dev's Flux so they could not be recreated).
  2. dev's 18 LEGACY UNPREFIXED TXT registry entries deleted from Cloudflare by
     hand. external-dns v0.21.0 deleted only the `a-` prefixed form and then logged
     "All records are already up to date" — it would NEVER have cleared the older
     unprefixed format it no longer writes but still READS for compatibility. They
     carried `owner=default`; prod runs `owner=prod`, so prod could not have
     claimed these names while they existed. This was the real blocker, and it was
     invisible until measured.
  3. dev's `*.home.keithjackson.dev` + apex Certificate deleted so it stops
     renewing. Issued ~18d ago, so prod's request is #1 this week against LE's
     duplicate limit (5 per identical name set per week).

Verified at the AUTHORITY (betty.ns.cloudflare.com), not via a resolver: 1.1.1.1
served stale TXT for minutes after deletion and would have shown a false failure.

UNCHANGED, deliberately: EXTERNALDNS_TXT_OWNER_ID stays `prod` — giving prod
`default` would let it adopt and sync-delete records it does not own, which is the
2026-09-04 incident. EXTERNALDNS_DOMAIN_FILTER stays the ZONE `keithjackson.dev`:
finding F-DNS1 proved a strict subdomain filter drops the hosted zone and external-dns
then publishes NOTHING.

The zone has wildcards `*.keithjackson.dev` and `*.home.keithjackson.dev` pointing at
the public IP (legacy non-k3s prod). Dev's specific records were shadowing the latter;
prod's new specific records shadow it again. The legacy stack lives on
`*.keithjackson.dev` and is untouched.

k3s_base_domain moves with it to hold the [parity] contract, but that value renders
the apiserver's install-time oidc-issuer-url: it does NOT take effect until the
k3s_server role re-renders config.yaml and k3s is restarted serial: 1. Until then the
apiserver trusts the OLD issuer while Keycloak serves the NEW one, so kubectl OIDC
fails in that window. Cert-based kubeconfigs are unaffected.

jakman85andClaude Opus 5 6202d92c27 test(conformance): gate the URL desired state, and prove the selftest can fail
L0 (212 assertions, was 175):
  * runs ci/render-keycloak-client-urls.py --check, so client-urls.yaml must be exactly
    what the realm import renders. A hand edit that makes the two disagree is
    unmergeable -- this is what keeps the realm import the single source of truth for
    hostnames rather than just the place they were first typed.
  * asserts client-urls.yaml and the realm import are rendered by the SAME Flux
    Kustomization. postBuild.substituteFrom is per-Kustomization, so a split would let
    one ${BASE_DOMAIN} resolve to two different values and the realm would converge on
    a hostname the HTTPRoutes do not serve.
  * asserts the desired state uses no substitution token the realm definition lacks,
    names only clients the import declares, and declares no field outside the
    five-field write surface; that the CronJob mounts it readOnly at the path the
    script defaults to; and that the script, renderer and check agree on which fields
    are writable.
  * NEW mutations.py: injects 12 plausible regressions into the EXTRACTED script and
    requires --selftest to catch every one. A passing suite proves nothing if it cannot
    fail, and "reported success while the realm was broken" is precisely what this
    component exists to end -- so the same standard applies to its own test. ~20s.

L2: the audit Job now mounts keycloak-client-urls and asserts
KEYCLOAK_CLIENT_URLS_AUDIT_OK. Without that it would pass on a realm still holding
pre-migration redirect URIs -- the exact state prod was measured in.

Alerts: the existing Failing/Stale pair is EXTENDED to name redirect-URI drift, not
duplicated. One CronJob gets one pair; a second pair on the same job_name regex would
fire twice for one cause. No new critical, no new permanently-firing rule.

jakman85andClaude Opus 5 23ea72d01e feat(keycloak): reconcile client redirect URIs, not just client secrets
The realm import is a one-shot that never re-runs, so a redirect URI changed in git
reaches the realm never. Prod's stored URIs were measured still on the pre-migration
hostname while git declared the new one -- after a BASE_DOMAIN flip every OIDC login
fails with a redirect_uri mismatch, with the CR still reading Done=True and nothing
alerting. Same failure class as the literal-placeholder secrets, same cure.

EXTENDS the existing reconciler rather than adding a sibling. Decisive reason: a URL
write needs NO new endpoint. It is the same minimal client PUT, and the current URLs
already come back in the allow-listed client lookup -- so the allow-list is widened by
nothing and the users/groups/roles/authentication guarantee is preserved unchanged
rather than re-declared in a second copy. The ConfigMap also carries exactly one
script key by L0 contract, so a sibling would have had to fork ~300 lines of
safety-critical code that the header explicitly forbids forking.

Reconciles redirectUris, webOrigins, rootUrl, baseUrl, adminUrl -- only the fields a
client actually declares, and on a write only the fields that actually drifted. A
field the desired state omits is UNMANAGED and left untouched; absence never means
force-to-empty.

THE TWO PASSES ARE INDEPENDENT. Each reads its own desired state and fails closed for
its own fields only. A malformed URL ConfigMap cannot stop client-SECRET repair, which
would otherwise make credential healing depend on a hostname file.

List fields compare order-insensitively (sorted, not set -- duplicates are still
drift), because Keycloak does not preserve the authored order of redirectUris and an
order-sensitive compare would rewrite every client forever while reporting success.

--selftest grows to 84 assertions covering the domain flip, a client gaining a URI, a
client losing a stale one, a public client's URLs being managed while its secret is
not, per-pass fail-closed, order-insensitivity, and a server that accepts a PUT
without applying it.

jakman85andClaude Opus 5 51d8676f90 feat(keycloak): render the client-URL desired state from the realm import
The realm import is a one-shot: once Done=True it never re-runs, so a redirect URI
changed in git never reaches the realm. Healing that needs a DESIRED STATE the
reconciler can read -- and the reconciler pod has no Kubernetes API access at all
(automountServiceAccountToken: false), so it cannot read the KeycloakRealmImport CR.
Its desired state must be mounted, hence a ConfigMap.

A hand-authored ConfigMap would be a second source of truth for every public
hostname in the realm, free to disagree with the import -- the same shape as the bug
being closed. So it is GENERATED from the import and the render is gated, the same
render==golden idiom catalog/render.py already uses for apps/.

URL strings are copied VERBATIM: a ${BASE_DOMAIN} token in the source appears
unchanged here, and both files are rendered by the SAME Flux Kustomization
(./platform-config), so both are substituted in one pass with one value. The
renderer never parses a hostname and never reads cluster-vars, so there is no
second place the domain can be decided.

jakman85andClaude Opus 5 fa4deac877 fix(conformance): the dirty-tree assertion must judge HONOURED evidence
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
One historical `-dirty` row reddened this gate permanently, even after a clean
re-run of the same test. status.py already resolves duplicates latest-wins
(latest_by_test), so a superseded row is not evidence of anything — but this check
iterated every row, so the poisoned row from the git_sha bug (fixed in the parent
commit) would have failed the audit forever.

The dirty-tree assertion is now scoped to rows status.py would actually honour, by
importing latest_by_test rather than reimplementing the rule, so the two cannot
disagree about which rows are live claims. Structural assertions — provenance keys,
sentinel, test-still-exists — still apply to EVERY row.

Nothing is erased: the row stays in the ledger and runs/20260913T014437Z-19fc8bc/
run.log stays committed. It simply stops being read as a live claim. Verified the
guard is intact afterwards — the check still REFUSES both forgeries it is built to
catch (a self-skip presented as a pass, and a proven row from the root commit).

A dirty-then-clean sequence is also the normal shape of noticing a dirty tree,
fixing it, and re-running; that should not permanently fail an audit.

jakman85 a317493bca merge: R-NET-06 re-proven on prod (recovery in <=3s) 2026-09-12 21:10:57 -05:00
jakman85andClaude Opus 5 c66a7e29e9 fix(conformance): the harness contradicted itself in two places
1. auditability-proofs-producible rejected any proven ledger row without a
   sentinel, with no layer exemption — while record_run.py DELIBERATELY records
   L0/L1 rows sentinel-less via its own SENTINEL_EXEMPT_LAYERS, because
   run_l1_offline.py renders skips as JUnit <skipped/> and those layers have no
   pass token to attribute. So ANY `--record` run touching L0 or L1 wrote a row
   this gate then rejected. Consequence: a requirement whose verifier set includes
   an L1 check could never be both PROVEN and L0-green — R-NET-06 is exactly such
   a requirement, and hit it the moment it was re-proven on prod. The check now
   honours the same constant instead of restating the policy, so the two halves
   cannot drift apart again.

2. git_sha() marked the tree dirty from tracked files, but conformance/runs/
   ledger.jsonl IS tracked — so the FIRST `--record` run of a session dirtied the
   tree and every LATER run was stamped `-dirty`, which check.sh then refuses to
   honour. Recording one test poisoned the next, and that cost a second live
   fault-injection run against prod to work around. Its docstring already stated
   the intent for the untracked runs/<id>/ half of the same artifact; the ledger is
   the tracked half. Now excluded via pathspec, mirroring status.py's
   IMPL_EXCLUDE_PREFIXES which already lists this path for the same reason.

Neither change weakens an assertion: (1) applies an exemption that already existed
and was already documented, (2) stops the recorder invalidating its own output.

jakman85andClaude Opus 5 155df8ee3f test(conformance): R-NET-06 PROVEN on prod — vpn-killswitch re-run from a clean tree
Supersedes the -dirty row from the previous commit by the ledger's own
append-only / latest-wins convention (lib/status.py latest_by_test): nothing
is rewritten, a newer row simply outranks the older one.

  runs/20260913T014923Z-9d0814a  vpn-killswitch (L3)  proven  env=prod
  git_sha 9d0814ae... (CLEAN — resolvable, so the freshness check passes)

Fault injection against LIVE prod, gateway k3s-prod-3. Timeline (UTC):

  01:49:27  tunnel-stop Job applied
  01:49:31  Job succeeded — host vpn-egress-tunnel STOPPED, tun0 gone
  01:49:31..01:51:01  vpn-class blackholed for 8 consecutive polls, NO response
                      of any kind; internet-class unaffected on the WAN
  01:51:02  self-healing finally: tunnel-restart Job
  01:51:05  kubectl wait confirms the host brought the unit back
  01:51:04  egress-uplink label AND the BPF egress map both move 134 -> 139
            (measured independently, out of band, during the run)
  01:51:08  vpn-class egress back on PIA 158.173.241.11

RECOVERY WAS UNAIDED and took ~3s from tunnel-up to a re-steered datapath —
far inside the ~2-minute convergence timer, so the EVENT-DRIVEN up-script
path did the work, not the timer backstop. This is the half that was
previously unprovable: before the egress-uplink label, Cilium held the stale
ifindex and vpn-class egress never came back.

WHAT THE NO-LEAK ASSERTION DOES AND DOES NOT PROVE: it proves vpn-class
fails CLOSED (zero packets out, never the WAN IP). It does NOT credit the
host nftables backstop, which provably cannot fire for pod traffic —
bpf_redirect() skips netfilter. Stopping the tunnel removes tun0 and Cilium
drops on its own because the cached egress ifindex is unusable. Fail-closed
is real; the mechanism is Cilium's drop, as the test header now says.

jakman85andClaude Opus 5 9d0814ae61 test(conformance): R-NET-06 run against prod — L1 proven, L3 pass recorded -dirty
Two recorded runs against PROD (CONF_ENV=prod, context k3s-prod):

  20260913T014321Z-19fc8bc  egress-class-render (L1)  proven
  20260913T014437Z-19fc8bc  vpn-killswitch      (L3)  proven, but git_sha -dirty

The L3 run PASSED for real on prod — every declared sentinel present
(NS_PRIVILEGED_OK, TUNNEL_HEALTHY_OK, NO_LEAK_OK, INTERNET_UNAFFECTED_OK,
TUNNEL_SELF_HEAL_OK, TUNNEL_RECOVERED_OK), tunnel stopped 01:44:48Z and
recovered unaided by 01:46:25Z.

Its row is nevertheless NOT usable as proof: git_sha carries `-dirty`, so
status.py's ancestry check cannot resolve it and the row degrades to
stale-proof. Cause is a harness flaw, not the cluster:
lib/record_run.py's git_sha() ignores UNTRACKED files (so a run's own
runs/<id>/ does not mark it dirty) but conformance/runs/ledger.jsonl is
TRACKED — so the FIRST --record run of a session appends a row, dirties the
tree, and every SUBSEQUENT --record run in that same session is stamped
-dirty. Recording one test poisons the proof of the next.

Committed as-is rather than rewritten: the ledger is append-only and this is
honest evidence of a real run. A clean re-run follows and supersedes it by
latest-wins (lib/status.py latest_by_test).

jakman85andClaude Opus 5 38e4bf1459 docs(vpn): record the PIA server collision, and the accidental proof it handed us
The stand-up broke dev, so the "one gateway per PIA server" rule and the
measurement behind it are now written down where the next person will look:
platform/vpn-egress/README.md and the session's DECISIONS-LOG entry. Both carry
the verbatim journal lines — same server, same pushed `ifconfig 10.72.192.7` on
both gateways — and the flap timestamps, because "same account, inside the
connection limit" is true and is exactly what makes this non-obvious.

Also corrected: the dev/prod table now shows the two environments on different
servers with different exit IPs (dev 158.173.241.36, prod 158.173.241.11), and the
open item about them sharing one public IP is replaced with the real remaining
decision — whether prod gets its own PIA account, which would remove the
hand-maintained per-environment server value entirely.

The unplanned bonus, recorded in both places: moving prod to .135 gave it a
genuinely NEW tunnel address on a real reconnect (10.72.192.7 ifindex 128 ->
10.150.192.86 ifindex 129) — the precise case Cilium does not follow and the one
defect 1 was about. The egress-uplink label moved on its own, Cilium re-resolved,
and all four vpn-class workloads kept egressing with no manual step. Better
evidence than the synthetic address swap used to characterise it, and it cost
nothing to capture.

jakman85andClaude Opus 5 37a6c94168 fix(vpn): two gateways on one pinned PIA server evict each other every 2 minutes
Standing up prod broke dev, and the mechanism is worth spelling out because
"same PIA account, well inside its connection limit" is true and still not enough.

The vaulted .ovpn pins ONE server. With both gateways using it, dev and prod
landed on the SAME server AND were handed the SAME tunnel address — both journals
read `[Server-10779-2a] Peer Connection Initiated with [AF_INET]158.173.241.112:1198`
and `ifconfig 10.72.192.7 255.255.192.0`. Each reconnect steals that address on
that server; the loser then receives nothing, trips `--ping-restart` after 60s,
reconnects and steals it back. Measured cycle: dev restarting at 22:57:05,
22:59:03, 23:01:05 UTC with prod interleaved about a minute off, each ~2 minutes
apart, indefinitely. Neither environment had reliable vpn-class egress — prod's
probes looked green only because they happened to land inside an up-window.

Fix: `vpn_egress_gateway_pia_remote` ("<host> <port>", empty = honour the .ovpn)
rewrites just the `remote` line of the deployed .ovpn, and prod's group_vars sets
it to 158.173.241.135. That is another member of the same PIA Stockholm LB pool —
`sweden.privacy.network` resolved from k3s-prod-3 to
158.173.241.{34,55,112,135,239} — and every server in the pool takes the same
credentials and the same inline CA, so only the address differs. Dev keeps the
.ovpn's .112 untouched, which is why the override is per-group rather than in the
role or a second vaulted .ovpn.

Two details that matter for whoever touches this next:

* The regex is anchored to a line STARTING with `remote` plus whitespace, so
  `remote-cert-tls` and `remote-random` are not collateral damage. The task keeps
  `no_log: true` — the transformation never widens what is logged.
* A PIA server address is NOT a credential, so it lives in
  group_vars/vpn_egress_gateway_prod/vars.yml in the clear, next to the vault
  rather than inside it. Keeping it out of the vault is what makes it reviewable.

If prod ever gets its own PIA account, this override can be deleted again.

jakman85andClaude Opus 5 04606d48b2 docs(vpn): stop crediting the nftables kill-switch for a drop it never makes
Four places in the tree told the reader that the host nftables table is the
authoritative fail-closed backstop for egress-class=vpn pods: platform/vpn-egress
README, egress-steering.yaml, the role README, and the vpn-killswitch test's own
GIVEN/THEN prose. It is not, and cannot be — Cilium's eBPF egress-gateway
datapath bpf_redirect()s those skbs to the egress device without invoking
netfilter POSTROUTING. Corrected with the measurement in each place rather than
softened, because a guard the repo trusts and that does not fire is worse than no
guard.

What replaces the claim, everywhere: vpn-class fails closed because CILIUM drops
the traffic when it cannot use its cached egress interface, verified by tcpdump on
both the WAN and tun0 during a tunnel stop and a tunnel restart (0 packets out
either). The nft table keeps a narrower, now-proven job: node-originated traffic
sourced from a tunnel address (killswitch_drop moved 0 -> 3 packets on
k3s-prod-3 when such a packet was routed at the WAN).

Also recorded:

* egress-steering.yaml — `interface: tun0` is resolved ONCE and cached, and the
  gateway node is what tells Cilium it changed (the egress-uplink node label). A
  future reader's instinct will be to have the node write to that object; the
  comment says not to, because it is Flux-managed, and points at the label and
  `cilium-dbg bpf egress list` as the debugging entry points instead.
* egress-steering.yaml — why the new NFS media mounts are not affected by
  pod-scoped steering: an NFS PV is mounted by the node kernel in the host netns,
  so podSelector never matches it. The 192.168.0.0/16 exclusion covers the server
  too, but that is the second reason, not the first.
* vpn-killswitch test — its recovery step depends on the re-steer path, and could
  not have passed before it existed. Its no-leak assertion was always right; only
  the explanation was wrong. Also states the prerequisite plainly: the test cannot
  run at all without a labelled gateway node.
* platform README — prod is live on k3s-prod-3 with the before/after egress IPs,
  and the note that prod's vpn-class pods had NO internet beforehand (CEGP with no
  matching node -> `Gateway IP: Not Found` -> dropped), so arming the gateway
  restored egress rather than moving it off the WAN.
* role README — the standing "add the shared fwmark to the interface contract"
  escalation is closed as not implementable on Cilium OSS, rather than left open
  for someone to attempt.

DECISIONS-LOG carries the full session entry, including the drafted ADR-0015 /
docs-03 amendment for the architect (specs are immutable to agents) and the five
things left for the operator — chief among them that a silent gateway outage still
has no alert, which is what let the dev gateway sit dead for 80 minutes.

jakman85andClaude Opus 5 60e3f09c67 feat(vpn): prod egress-gateway group — k3s-prod-3, singleton, opt-in only
`[vpn_egress_gateway_prod]` is a SEPARATE inventory group with its own vaulted
credentials, not a second member of `[vpn_egress_gateway]`. That group is the
default target of playbooks/vpn.egress.gateway.yml, so adding a prod host to it
would mean a flagless `ansible-playbook playbooks/vpn.egress.gateway.yml`
silently reconfigures a prod node's kill-switch datapath. Prod is reached only by
asking for it, with `--list-hosts` first:

  -e vpn_egress_gateway_hosts=vpn_egress_gateway_prod --limit k3s-prod-3

Node 3 because node 1's SSD was replaced yesterday (least operational history)
and node 2 carries the §0b memattr history. Exactly one node, forever: Cilium OSS
picks "the first node in lexical ordering" among nodeSelector matches, so a
labelled k3s-prod-1 would silently steal the gateway role — and the public egress
IP — from k3s-prod-3, with no event and no alert.

vault.yml is a verbatim copy of the dev group's CIPHERTEXT: same PIA account per
the operator, and copying the encrypted blob means the plaintext was never
decrypted to disk, through a shell, or into a transcript. The two files are now
independent — rotating means re-encrypting both, which is the right behaviour for
two environments.

Also corrects a stale inventory note that claimed k3s-prod-3 has wlp1s0 up on
192.168.2.195. Re-verified before choosing it as the gateway, because a second
live uplink in a kill-switch datapath is not a footnote: there is no wl* netdev on
the node at all, no phy80211 device, the /etc/network/interfaces wlp1s0 stanza is
commented out, 192.168.2.195 is assigned nowhere, and the only IPv4 addresses are
lo and eno1 192.168.2.12. Nothing needed bringing down.

jakman85andClaude Opus 5 6f698f59af fix(vpn): Cilium never re-resolves tun0 — the gateway dies on every reconnect
Measured on k3s-dev-3, not reasoned about. Three findings, one of which had the
dev gateway silently dead for ~80 minutes before this change:

1. Cilium caches (egress IP, egress ifindex) when it first resolves the CEGP's
   `interface: tun0` and does NOT re-resolve when tun0 changes. Every tunnel
   restart re-creates tun0 with a NEW ifindex, so vpn-class egress is blackholed
   from then on. Observed: node had tun0 at ifindex 1987 while `cilium-dbg bpf
   egress list` still said 1986; pod curl timed out. Forcing a re-apply moved the
   map to 1987 and egress recovered instantly. `egress-gateway-reconciliation-
   trigger-interval: 1s` does NOT cover netlink link events — dev has that same
   1s setting and still did not self-heal, 20s+ after recovery.

   Fix: vpn-egress-resteer.sh publishes "<tun0 addr>-<ifindex>" as a node label.
   A node update makes the gateway re-process the policy (verified: cached
   ifindex 1986 -> 1987 within 10s). A node label, not an annotation on the
   policy, because the policy is Flux-managed GitOps and the node's labels are
   already this role's territory. Fired by the OpenVPN up-script on every
   connect, plus a 2-minute convergence timer for the boot case where the
   kube-API is not up yet. Proof: `systemctl stop` then `start` of the tunnel now
   recovers on its own (map 1989 -> 1990, PIA IP returns); before this commit the
   identical sequence stayed broken indefinitely.

2. The nft kill-switch CANNOT see the traffic it claims to guard. A counters-only
   diagnostic table on the gateway node recorded, while a vpn-class pod egressed:
   0 packets in forward and 0 in postrouting for both the pod CIDR and the PIA
   range, against 45166 packets on the same postrouting hook for WAN traffic and
   16 packets for a node-originated curl out tun0. Cilium's eBPF datapath
   bpf_redirect()s these skbs to the egress device without invoking netfilter.

   So `ip saddr @set oifname != tun0 drop` can never fire for vpn-class pods.
   What actually fails closed is Cilium's own drop when the cached egress
   interface is unusable — tcpdump during a tunnel stop AND during a restart
   showed 0 packets leaving either the WAN or tun0. Every rule now carries a
   `counter` so the claim stays falsifiable, and every comment that called this
   table the authoritative vpn-class backstop is corrected rather than left to
   mislead the next reader.

   Also removed the `meta mark 0x1c8 oifname != tun0 drop` rule and its variable:
   nothing stamps that mark (the only Cilium mark on the node is 0x200/0xf00, the
   L7-proxy rule to table 2004), the traffic never reaches netfilter anyway, and
   a live rule matching an arbitrary mark is a hazard to whatever picks it next.

3. The up-script flushed the nft source set on every connect, so a packet still
   sourced from the previous tunnel address matched neither the ip-rule nor the
   drop rule. The set is now additive (`add element` is idempotent; the
   down-script already retained it): an element can only ever tighten the guard.
   Finding 2 means that window could not have leaked POD traffic, but
   node-originated tunnel traffic does traverse netfilter, and additive is free.

Kill-switch reloads no longer disarm the guard either: the .nft file uses
`table` + `flush table`, which clears rules but leaves the named set's elements
intact, so an Ansible run cannot empty the set mid-flight.

jakman85andClaude Opus 5 2d5171e064 feat(velero): scrape the backup controller — three critical alerts could never fire
platform/monitoring/alerts.yaml has shipped VeleroBackupFailure (critical),
VeleroBackupPartialFailure and VeleroNoRecentBackup since the observability
wave. None of them could ever have fired. The velero chart defaults
`metrics.serviceMonitor.enabled: false`, and prod confirms it live:
`kubectl -n velero get servicemonitor` returns no resources, so
velero_backup_failure_total and velero_backup_last_successful_timestamp were
never scraped. A nightly backup could fail — or silently stop running — for
weeks with nothing to say so. That is exactly what R-STATE-03 is for, which
makes the scrape part of the backup path rather than an observability extra.

Both flags verified against chart 12.1.0: `helm template` emits neither object
without the monitoring.coreos.com/v1 capability, and emits both PodMonitor and
ServiceMonitor with it — so the chart gates on capability detection AND
`enabled`, and helm-controller supplies real capabilities from the API server.
No additionalLabels are needed: platform/monitoring already sets
serviceMonitorSelectorNilUsesHelmValues and podMonitorSelectorNilUsesHelmValues
to false, so Prometheus selects every monitor regardless of labels.

Independent of the R2/bulk-tier fix in the previous commit; droppable on its own
if the PM wants to sequence it separately.

jakman85andClaude Opus 5 2e259a808f fix(velero): prod backups could not write metadata to R2, and opt-out FSB would have shipped 8.6 TiB
Velero was resumed on prod (live `flux resume`; suspension was never in git) and
its BackupStorageLocation validated Available against Cloudflare R2 on the first
try — bucket k3s-prod-backup, prefix `velero`, region auto, checksumAlgorithm "".
Backups still failed, and a second, unrelated hazard was armed. Both are fixed
here; both were measured on prod, not reasoned about.

1. velero-plugin-for-aws v1.14.2 cannot write to R2 at all.
   It sets PutObject's `Tagging` field unconditionally, so the SDK emits an empty
   `x-amz-tagging` header on every PUT. R2 does not implement object tagging in
   any form and answers HTTP 501 NotImplemented. Two separate Backups reproduced
   it on the write of velero/backups/<name>/velero-backup.json: kopia uploaded
   the volume data fine (it uses its own S3 client), then the backup went
   phase=Failed with no metadata object — i.e. unrestorable. No config avoids it;
   `config.tagging` with a real value sends a tag set R2 also rejects. Upstream
   PR #309 makes the field conditional and landed on release-1.14 after v1.14.2
   was cut, so v1.14.3-rc.2 is the earliest build with the fix. Pinned to it,
   with the exit condition (v1.14.3 GA) stated at the pin.

2. The opt-out FSB schedule would have uploaded the NFS bulk tier.
   Schedule (1) runs defaultVolumesToFsBackup:true and excludes only monitoring
   and unifi. Since 2026-09-11 prod also carries four static NFS PVs —
   plex-media, sonarr-media and radarr-media all bound to the SAME export
   /mnt/Storage/plex (8.32 TiB measured via zfs list), plus
   nextcloud-legacy-archive at 270 GiB. The 03:00 run would have read that
   library three times over NFS and pushed ~8.6 TiB to R2 nightly, retained
   720h. Namespace exclusion cannot express the fix: those four namespaces also
   hold real Longhorn PVCs (plex/sonarr/radarr config, nextcloud-data) whose
   loss is unrecoverable.

   So the opt-out is now per VOLUME, by SOURCE TYPE: a velero volume policy
   (ConfigMap velero-volume-policies) skips any volume whose source is NFS, and
   schedule (1) references it. That tests the property that makes a volume
   bulk-tier (R-STATE-04: the bulk tier IS the NFS export) instead of a name list
   the next PV would slip past. The per-pod backup-volumes-excludes annotation
   was rejected for failing OPEN — a new NFS mount would be backed up in full
   until someone remembered.

   PROVEN on prod (velero 1.18.1 / chart 12.1.0): a Backup of ns nextcloud with
   defaultVolumesToFsBackup:true plus this policy produced exactly ONE
   PodVolumeBackup — `data` (nextcloud-data, Longhorn, 875,417,102 bytes,
   Completed). The NFS `legacy-archive` volume produced none.

Residual gap, stated rather than hidden: the rule matches NFS only. A future
bulk volume on another out-of-cluster source needs its own condition.

jakman85andClaude Opus 5 5da116b34d fix(oauth2-proxy): platform-admins may reach the media UIs — the immediate 403
The four forward-auth media UIs (jackett, qbittorrent, radarr, sonarr) gate on
`--allowed-group=media-users` alone. On prod the `homelab` realm has exactly one
user — the operator's `jakman85` — and it is a member of `platform-admins` ONLY.
`media-users` has zero members, so those four hosts were reachable by nobody:
oauth2-proxy completed OIDC discovery, redirected to Keycloak, got a token whose
`groups` claim is `["platform-admins"]`, found no allowed group in it, and
answered 403. No login form appeared because the browser already held a Keycloak
SSO session from a platform-admins login — hence "403 immediately".

pihole and crafty were unaffected: they already gate on platform-admins.

`--allowed-group` is repeatable and OR-ed, so listing both groups means "media
consumers OR platform operators". This grants no real privilege — platform-admins
already maps to cluster-admin via k8s-oidc-rbac.yaml (oidc:platform-admins), so a
member can already exec into these pods — and it keeps media-users meaningful for
non-admin household accounts.

Ruled out while diagnosing: client-secret drift (all 7 sidecar secrets hash-match
keycloak-realm-clients), stale apex URLs (every live sidecar carries
keycloak.prod.home.keithjackson.dev), missing group mappers (all 7 clients emit
claim=groups, full.path=false), and the central oauth2-proxy pod restarts — those
were Keycloak returning 503 "no healthy upstream" to OIDC discovery at startup, a
consequence of the Keycloak roll, not a cause.

Goldens re-rendered with the canonical command:
  python3 catalog/render.py --all catalog -o apps --wave-layout --no-image-automation
