jakman85andClaude Opus 5 a79693d3bd feat(monitoring): scrape the Flux controllers — five gotk_* alerts were inert
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
kube-prometheus-stack does not scrape flux-system: the controllers are
bootstrapped, expose no Service, and no chart value covers them. So every
gotk_* alert rule in platform/monitoring/alerts.yaml could never fire —
verified on prod, count({__name__=~"gotk.*"}) returned nothing. A repo whose
entire delivery model is Flux had no alerting on reconciliation failing, a
Kustomization erroring, or a resource left suspended.

Proven live before landing: with this PodMonitor applied, gotk_suspend_status
returns 39 series and gotk_reconcile_condition 117, and FluxResourceSuspended
actually fired on a deliberate test suspension — evidence the rule is live,
not merely present.

Extracted from the wider inert-alert audit on
fix/scrape-targets-for-inert-alerts, which stalled unfinished. This is the
self-contained, verified half; Longhorn and cert-manager metrics are still
ABSENT and their alerts remain inert. It also adopts the object into git: it
existed on prod only as kubectl-client-side-apply, so a rebuild would have
lost it.

jakman85andClaude Opus 5 16b7fcd677 fix(cnpg): the grant reconciler died on every Flux-managed run
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
The SQL asserted convergence in a dollar-quoted PL/pgSQL DO block. That
cannot survive this delivery path: the ConfigMap is rendered through Flux's
postBuild substitution, and envsubst collapses a doubled dollar into one, so
Postgres received a half-quoted DO and failed with a syntax error. Three
scheduled runs had left nine Error pods in nextcloud-db.

It passed verification because it was hand-applied with kubectl, which runs
no envsubst — the defect only existed once Flux owned the object. The GRANT
on the first line still succeeded, so the privilege held and the blind spot
stayed closed; what was broken was the assertion meant to prove it, which is
the part that makes a silent regression visible.

Rewritten in plain SQL with no dollar sign anywhere in the file, comments
included. Escaping by doubling again would also work and would be the next
person's trap. has_database_privilege()::int is 1 or 0, so the division
raises division_by_zero and ON_ERROR_STOP=1 fails the Job; the divisor is
not constant so it cannot be folded away at plan time.

jakman85 5fa893095b merge: the placeholder guard test was hiding a RED, not a pass
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
It had been permanently SKIPPED because it expected bootstrap/standup.sh,
which never landed on main — planned, never merged, still living only on the
unmerged prod-standup branches along with the 2026-09-05 incident it came
from. Dropping the real script in and running the old check produced FAIL
2/34: it would have false-blocked the very merge that landed its own input.

Now split into the half that needs no guard (no overlay ships a
placeholder-shaped effective cluster-vars value; an empty value must be
STATED by the overlay, not inherited in silence; a loud base sentinel must
be explicitly overridden) and the half that self-activates. The guard is
discovered by CONTENT — any tracked *.sh defining <name>_is_placeholder() —
so landing one anywhere activates the second half with no edit here, and two
definitions is a failure. The check never exits 3 again.

Unscoped L0 goes 13 PASS / 1 SKIP -> 14 PASS / 0 SKIP.

jakman85 e49b86eb41 merge: 35 runbooks, served, with a guard that they resolve
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
All 46 runbook_url annotations pointed at https://<apex>/runbooks/<name>
and every one returned 404 — there was no runbooks/ directory and no route.
Every alert that reached a human handed them a dead link at the moment they
needed it.

Runbooks are now served from their own non-gating tier at the apex prefix,
PUBLIC on purpose: gating them behind Keycloak would make keycloak-down
unreadable exactly when Keycloak is down, which is a loop with no exit. The
new L0 guard checks both directions — a runbook_url with no file, and a file
not wired into the generator — and it caught a live one on contact with
main: CNPGPrimariesCoLocated had shipped hours earlier pointing at a runbook
that did not exist.

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 87c3d83dff fix(conformance): placeholder-guard-coupling actually RUNS — it was skipping forever
`conformance/tests/l0-static/placeholder-guard-coupling` (R-ENV-02, R-STATE-03) exited 3
SKIPPED on every gate run since it landed, because its check keyed its whole existence on
`bootstrap/standup.sh`. Measured, not assumed: that file has NEVER been on `main` — there is
no deletion commit for it anywhere; it landed only on unmerged prod-standup branches
(`work/prod-standup-campaign`, `prod/*`, `feat/prod-hardening`). It was planned and never
merged, not removed. SKIPPED is not green, and a permanently-skipped incident-derived test is
the quiet version of the failure it was written to prevent.

The skip was also hiding a RED. Run against the real `standup.sh` from
`work/prod-standup-campaign`, the old check FAILED 2 of 34 assertions — false positives from
treating the empty string as placeholder-shaped for knobs cluster-vars authors empty on
purpose (`BACKUP_CREDENTIALS_SUFFIX`, `VELERO_BACKUP_PREFIX`, both `""` on dev and both
documented there as load-bearing). It would have false-blocked the merge landing its own input.

NOT deleted — the hazard is not gone. Split into two halves, one of which needs no guard:

  HALF A (always runs): no environment overlay ships a placeholder-shaped EFFECTIVE
  cluster-vars value; an empty effective value is STATED by the overlay rather than inherited
  in silence; a LOUD base sentinel is explicitly overridden by every overlay. This is the
  2026-09-05 outcome asserted at the source instead of at the guard — if prod's
  S3_BACKUP_ENDPOINT is never a placeholder, velero cannot be pointed at a hostname that does
  not exist. Input surface is `clusters/`, all of it on `main`.

  HALF B (self-activating): the real predicate extracted and executed against those same
  values, the consumer trace, and the mid-string anchoring property.

The check NEVER exits 3 again, and the guard is DISCOVERED by content rather than hardcoded:
any tracked `*.sh` defining `<name>_is_placeholder()` is found, so a guard landing at
`bootstrap/standup.sh` — or moved into a sourceable library, the remedy the check already
recommends — activates HALF B with no edit to the test. Two files defining it is a FAIL. When
no guard exists the gap is printed loudly every run instead of swallowed as a skip.

LOUD vs EMPTY is the correction that makes it honest in both modes: a loud placeholder is
always a defect in an overlay, while `""` is held to the explicitness rule instead — and still
counts as a placeholder for a knob a guard covers, because a `""` case-arm is the guard
author's declaration that empty is not a usable target.

Proof, all reverted: 84 assertions and exit 0 on `main`; prod S3_BACKUP_ENDPOINT set to the
literal `https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com` FAILS (A1); deleting dev's
explicit VELERO_BACKUP_PREFIX op so it inherits `""` FAILS (A2); a LOUD base BULK_NFS_SERVER
with prod's override deleted FAILS 2/86 (A1+A3); and with the real `standup.sh` present,
reverting `s3_is_placeholder` to the `TBD-*` PREFIX glob FAILS 12/110 (B3 anchoring). With the
pristine `standup.sh` the check PASSES at 110 assertions where the old one failed 2 of 34.

L0 layer: 14 checks, 14 PASS, 0 SKIP, 0 FAIL (was 13 PASS / 1 SKIP). Coverage unchanged —
R-ENV-02 and R-STATE-03 both still list this test, 49/51 with the same 2 gaps.

Also:
  * `ci/touched-requirements.sh` — `bootstrap/*` -> R-STATE-03 R-GITOPS-01 is KEPT, its stale
    comment corrected. It claimed standup.sh "carries the placeholder guards", describing a
    file that is not here; R-STATE-03 there is ANTICIPATORY. Deleting the entry would leave the
    change that lands a placeholder guard selected by nothing.
  * `ci/tests/touched-requirements.test.sh` — new path-map section (12 assertions, was 8)
    locking `bootstrap/*` and `clusters/*`, so removing either entry is a test failure rather
    than a silent loss of selection. All three ci/tests pass (12 + 31 + 15).
  * `docs/BULK-NFS-STORAGE.md` §7 — its "nothing in the gate currently refuses a
    placeholder-shaped overlay value" is no longer true; corrected.
  * Scope re-audited: still deliberately requirement-scoped, not whole-repo. Every path that
    can break it attributes a requirement it declares.

jakman85andClaude Opus 5 bce8778096 docs(runbooks): forward-auth IS enforced — correct the posture note
The serving route's comment claimed that because no Gateway ext-authz
attachment exists, every forward-auth route is 'in practice reachable
unauthenticated today'. That is wrong, and wrong in a dangerous direction
for a document an operator reads during an incident.

Enforcement here is PER-POD, not gateway-level: each of the five services
declaring auth: forward-auth (pihole, jackett, qbittorrent, radarr, sonarr)
publishes both its app port and 4180 on its Service, and its HTTPRoute
targets :4180 — the oauth2-proxy sidecar. Verified on prod. The app port
remains reachable in-cluster on purpose, which is how sonarr/radarr drive
qBittorrent's API, and Cilium default-deny governs that path.

The public-by-design decision for this route is unchanged and still correct;
what changes is that it is genuinely the exception rather than one open route
among many. Headlamp's exclusion is likewise deliberate (native OIDC with
per-user id_token forwarding and no ServiceAccount cluster rights).

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.

jakman85andClaude Opus 5 b7341b329b fix(runbooks): declare whole-repo scope, drop the bespoke l0 stage, +cnpg-primary-spread
Three corrections after rebasing onto main.

1. THE GUARD CAUGHT A REAL ONE ON ITS FIRST CONTACT WITH main. main had gained
   `CNPGPrimariesCoLocated` (platform/cnpg/alerts.yaml) pointing at
   /runbooks/cnpg-primary-spread, with no runbook. The check failed the rebase exactly as
   designed — 46 annotations, 35 names, 34 present — naming both the missing file AND the
   missing configMapGenerator entry. runbooks/cnpg-primary-spread.md now exists: what
   co-located primaries actually cost here (blast radius, not an outage, because
   instances: 3 + required anti-affinity), why the drift is uncorrectable-by-declaration
   (CNPG has no primary-placement field), the readiness gate that keeps the rule quiet
   during a real node outage, and the ~9s-per-database switchover rebalance, one cluster
   at a time. The 2026-09-07 outage in which all three primaries sat on one node is the
   reason the alert exists at all.

2. WHOLE-REPO SCOPE, NOT A HAND-WRITTEN STAGE. main's refactor replaced ci/l0.sh's
   per-check "UNCONDITIONAL" stages with a declaration:
   `conformance.home.k3s/scope: "whole-repo"`, unioned into every gate run by Stage 3b's
   `--include-scope`. My +38-line Stage 3f is removed (ci/l0.sh is now byte-identical to
   main) and the annotation is declared instead. Assertion (7) of the check was rewritten
   to match: it no longer asserts its own path appears in ci/l0.sh — it asserts the test
   DECLARES the scope and that ci/l0.sh still passes --include-scope, since neither half
   alone makes the check load-bearing. That matters here because
   ci/touched-requirements.sh maps platform/monitoring/* to "R-OBS-01 R-OBS-02", not
   R-OBS-04, and maps platform/kubevirt/* and runbooks/* to nothing at all.

3. A FACTUAL CORRECTION IN ALL 35 RUNBOOKS. Every page claimed `dev.sh` defaults its
   current-context to k3s-dev. main's `9b4744d fix(devcontainer): dev.sh defaults to
   prod` made that false, and a runbook that misstates which cluster a command talks to is
   worse than one that says nothing. The pages now say what is durably true: the default
   has already changed once, so naming `--context k3s-prod` is what makes a command mean
   the same thing next month, and the per-invocation banner is there to be read. The
   check's own failure message was corrected the same way.

Re-verified after all three: check green at 374 assertions (46 annotations, 35/35 runbooks
present, 35/35 projected), re-applied to prod, and re-probed in-cluster through the
Gateway — node-down, keycloak-down, keycloak-client-secrets, cnpg-archiving,
longhorn-faulted, vpn-down, node-io and cnpg-primary-spread all HTTP 200 with
text/plain; charset=utf-8 and 8.9-12.1 KB of real body; /runbooks/ index 200; an unknown
name 404s with a pointer rather than a blank page; and homepage still answers the apex `/`,
confirming Gateway API longest-path precedence.

Full merge gate: PASS (spec-immutability, lint, l0, render-golden, l1 all green;
prom-rules SKIPPED for want of promtool in the image; L2/L3 SKIPPED, no cluster).

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.

jakman85andClaude Opus 5 44983095e1 feat(runbooks): make the 42 alert runbook_url annotations resolve
Every platform-health alert rule carries
`runbook_url: "https://${BASE_DOMAIN}/runbooks/<name>"` — 42 annotations over 34
distinct names, across platform/monitoring/alerts.yaml,
platform/monitoring/pvc-capacity-alerts.yaml, platform/cnpg/alerts.yaml and
platform/kubevirt/alerts.yaml. There was no runbooks/ directory and no HTTPRoute
serving that path: an in-cluster probe of
https://home.keithjackson.dev/runbooks/node-down returned HTTP 404. Every alert that
reached a human handed them a dead link at the exact moment the documentation is read,
and the annotation made it look solved — the same green-surface-over-absent-mechanism
class as the import Job that reported success while storing placeholder secrets.

No alerts.yaml is touched and no runbook_url value changes. The existing URL scheme is
made to resolve instead.

WHAT LANDS
- runbooks/<34>.md — one per name, each grounded in this cluster's real topology and,
  where one exists, its real incident history: the 2026-09-07 k3s-prod-1 etcd I/O
  starvation (measured PSI 11.36 vs 0.75/1.29, the exact journal lines, the four
  mechanisms proven inert), the Longhorn reboot tax and the freeze/thaw of
  concurrent-replica-rebuild-per-node-limit, Cilium's once-resolved egress interface
  cache (Ifindex 3 against a live 1780) and the absence of OSS failover, the CNPG
  38-hour ContinuousArchiving=False with its measured 6.8 MiB/h disk-full clock and the
  2026-09-12 aggregation-scope fix, the 2026-09-06 Keycloak lockout in which all 12
  clients held literal placeholder secrets behind an entirely green cluster, the Velero
  R2 x-amz-tagging NotImplemented incompatibility and its v1.14.3-rc.2 pin, and swap
  re-enabling itself across reboots via systemd-gpt-auto-generator.
  Each page states what the alert means HERE, the first diagnostic commands, likely
  causes ordered by probability with a remediation each, and when to escalate or stop.
- Every page uses FULLY-QUALIFIED resource names and says why: three CRDs register the
  kind `Backup` here, the bare short name resolves to Longhorn's (zero objects), so
  `kubectl get backup -A` prints "No resources found" on a cluster holding 6 Velero and
  27 CNPG backups. Acting on that false negative is how a CLI quirk becomes data loss.
- Every page states that kubectl only works via
  `infra/devcontainer/dev.sh run bash -c '...'` with an explicit `--context k3s-prod`,
  because dev.sh defaults its current-context to k3s-dev.
- Pages also record which alert groups are INERT today (measured 2026-09-13: no
  Longhorn, cert-manager, Flux-controller or Hubble scrape job exists, so 13 rules
  evaluate against nothing) so nobody reads their silence as health.

SERVING — runbooks/serving/ plus clusters/base/runbooks.yaml
A two-replica nginx-unprivileged serving a ConfigMap generated from runbooks/*.md, at
the apex `/runbooks` prefix, in its own non-gating post-platform Flux tier
(dependsOn platform-config, wait:false) — the platform/homepage pattern, file for file.
- The service catalog cannot express this route: ingressRoutes[].host is pattern-bound
  to a single DNS label plus the apex, so the bare apex is unrepresentable, and there is
  no path field.
- Rejected: redirecting to the Gitea web UI. A runbook is read when the platform is
  broken, and Gitea is an app-tier workload whose own dependencies several of these
  runbooks document; Gateway API's RequestRedirect also has no "append .md" modifier,
  so it would need 34 hand-maintained ReplaceFullPath rules.
- configMapGenerator maps each file to an EXTENSIONLESS key (node-down=node-down.md),
  so /runbooks/node-down is a plain static lookup with no rewrite rule. Served as
  text/plain: the namespace has DNS-only egress, so a CDN markdown renderer could not
  load anyway.
- The tier declares NO postBuild.substituteFrom, deliberately: envsubst would run over
  the prose and silently empty every ${...} shell example (it fails open — the 2026-09-01
  emptied Cilium k8sServiceHost). The HTTPRoute omits `hostnames:` and inherits the
  https-apex listener's, so nothing needs substituting.

AUTH — PUBLIC, deliberately
auth-mode=none. Gating these pages behind oauth2-proxy/Keycloak would make
runbooks/keycloak-down unreadable when Keycloak is down and
runbooks/keycloak-client-secrets unreadable during the exact 2026-09-06 failure mode.
An operator who cannot log in is this route's primary reader. Content is operational
procedure only, no secrets. The rationale is recorded in an annotation on the HTTPRoute
so the route is left OUT of the Gateway ext-authz attachment when forward-auth
enforcement lands.

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.

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

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 5e7ab65c65 docs: kubectl get backup lies on this cluster — ambiguous Backup short name
Three API groups register kind Backup (longhorn, cnpg, velero). The bare
short name resolves to Longhorn's empty set, so kubectl reports absence
while 27 CNPG backups and live Velero backups exist. A false negative on
'do I have backups' is the worst possible time to be wrong, so record the
rule: fully-qualified resource names only.

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.

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).

Closes the loop on the collision entry with the recovery evidence rather than
leaving it as an open question for the operator: dev's last Inactivity timeout is
23:05:06 UTC — the minute prod switched to .135 — and at 23:12:03 that same
session was still the live one, seven minutes unbroken against a two-minute
cycle, 4/4 ping replies at 146 ms, 0% loss, and vpn-class pod egress back to
158.173.241.36 on three consecutive probes.

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.

jakman85andClaude Opus 5 6b953cc56b fix(arrs): the config PVC was mounted where the app never looks
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
sonarr, radarr, jackett and qbittorrent all mounted their Longhorn config PVC at
the renderer's default /data/config, but every one of these images runs with
`-data=/config`. So the PVC held nothing but lost+found while the app wrote its
entire configuration to the container's EPHEMERAL writable layer — destroyed on
every pod recreation: restart, reschedule, image bump.

Measured in-cluster before fixing, per app, rather than inferred:
  /data/config  dev=2080  [lost+found]                      <- the Longhorn PVC
  /config       dev=2053  [Sentry asp config.xml logs ...]   <- the node's own disk
and a marker file written to /config did not appear in /data/config, so they are
demonstrably different storage. qbittorrent's /config sat on dev=66309
(/dev/nvme0n1p5), i.e. whichever node it happened to land on.

This is the SAME failure catalog/plex.yaml:54 already records having fixed for
Plex; plex was the only one of the five that was right.

The live /config contents were copied onto each PVC BEFORE this landed, so
jackett's API key and qbittorrent's credentials — which other apps reference —
survive the move rather than being regenerated.

catalog/sonarr.yaml:61 documented this as a latent bug and deliberately left it
because it changes live on-disk state. It is being fixed now because all four pods
had just been recreated, so their configs were freshly generated and nothing had
accumulated to lose.

jakman85andClaude Opus 5 daac05e7e8 feat(bulk): prod mounts the NFS export through pfSense's WAN address
The operator added the pfSense port-forward, so BULK_NFS_SERVER is no longer a
placeholder. Prod gets 192.168.2.102 (pfSense WAN, DNAT tcp/2049 -> 192.168.1.9);
dev stays on the base 192.168.1.9 because it is already on pfSense's LAN.

This value could not be left as a placeholder safely: spec.nfs.server is
unvalidated by Kubernetes, so the PV would be created, the PVC would BIND, and the
failure would only surface as four pods stuck in ContainerCreating.

Verified from k3s-prod-1 before committing, deliberately as uid 1000 rather than
root (the export carries no_root_squash, so a root write proves nothing, and LSIO
images default to PUID 911 which would go Ready and then fail every import EACCES):
mount negotiated nfs4 vers=4.1 proto=tcp, write succeeded, and ln() across
downloads/ -> tv/ gave link count 2 — real hardlinks, so no silent copy-then-delete.

The Nextcloud export was additionally tightened to server-side ro= for prod's three
nodes; a write as root is refused. Its content is config/, config_old/ and
config_backup/ with no data/ directory, so it is an archive, not a live data store.

jakman85andClaude Opus 5 da8a0eac04 test(l0): R-STATE-04 gets a real check — bulk storage provably is not the replicated tier
The gate BLOCKED this branch, correctly, and the block was the interesting part.

Attaching the media library selects R-STATE-04 as a touched requirement ("bulk media storage has
a capacity strategy distinct from the replicated tier"), and R-STATE-04 had NO scaffolded test, so
the coverage REQUIRE stage failed both l0 and l1. There were two ways out. One was to keep
avoiding the token — the existing discipline in catalog/plex.yaml and catalog/qbittorrent.yaml,
which say in as many words that naming the requirement would block the merge. That made sense while
the tier was a stub. It does not make sense in the change that DELIVERS the tier: it would mean
shipping the requirement and claiming nothing. So: the check.

WHAT IT ASSERTS, and why each one is a real failure mode rather than a shape
The `bulk` StorageClass sat as `server: REPLACE-ME` for six roadmap phases, and the only thing
keeping a multi-terabyte library off the 3-replica `longhorn` class was four hand-written comments.
That is the class of failure being closed: a bulk volume on the replicated tier does not fail
loudly — Longhorn accepts the PVC and starts replicating 3x of data three mini-PCs cannot hold.

  (1) DISTINCTNESS — no bulk PV/PVC on any class the repo declares with the Longhorn provisioner
      (derived from platform/longhorn/, so adding a Longhorn class cannot create a blind spot),
      and the class is explicitly EMPTY.
  (2) CAPACITY STRATEGY as arithmetic — a bulk volume at least an order of magnitude above the
      same service's replicated volume. The requirement is about two magnitudes of data; a "bulk"
      volume sized like a config PVC means the tier was named, not applied. The 10x floor is
      CALIBRATED against the real corpus, not guessed: the media library is ~460x its config
      volume and the Nextcloud archive ~13x its 20Gi, so a higher floor would fire on a legitimate
      volume and teach the next reader to weaken the check. My first draft used 100x and did
      exactly that — the corpus caught it.
  (3) PRE-BOUND FROM BOTH ENDS (claimRef + volumeName, agreeing). Guards the most deceptive
      failure available in this tier: a dynamic bulk class hands out a FRESH EMPTY directory, the
      pod mounts, the PVC Binds, everything is green, and the 8 TiB was never attached.
  (4) Retain, always. (5) mountOptions carry `hard` and exactly one nfsvers=4.x, and never `soft`
      — a soft mount hands a server hiccup to the app as a short read, which for a media library
      is silent corruption; and v4 is what keeps the firewall surface at one port.
  (6) ONE EXPORT, AT MOST ONE MOUNT PER WORKLOAD. This is the assertion I most wanted. Splitting
      one export into two subPath mounts looks TIGHTER and breaks link() with EXDEV; Sonarr and
      Radarr then degrade to copy-then-delete, rewriting every import over NFS and destroying the
      seeding copy, surfacing weeks later as "imports are slow and my ratio is gone". No reviewer
      sees that in a diff.
  (7) READ-ONLY COUPLING — nfs.readOnly, the volumeMount flag and ReadOnlyMany must agree, so
      dropping one still leaves the others; and every bulk mode is a `...Many`.
  (8) The server is a BARE cluster-vars token, that knob has a base default, and EVERY overlay
      supplies it — the seam that lets one authored definition serve two clusters that reach this
      host by different addresses.
  (9) LOAD-BEARING and NON-VACUOUS. Wired unconditionally into ci/l0.sh as Stage 3e for the same
      reason as 3c/3d: Stage 3b scopes to touched requirements, and the path map keys NEITHER
      apps/* NOR platform/longhorn/* to this requirement — so the change most likely to break
      this could attribute nothing and be gated by nothing. An EMPTY bulk corpus FAILS rather
      than passing trivially, and a floor on the assertion count keeps a pass from degenerating.

It reads the COMMITTED apps/ goldens rather than calling the renderer. Asking the renderer would
only prove it agrees with itself; the goldens are what Flux reconciles, and render==golden is
already its own gate stage.

PERTURBED, because a check that has never failed is not evidence. Each of these was applied to the
real tree and each fired with the intended message: bulk PVC moved onto `longhorn`; Retain -> Delete;
`hard` -> `soft`; the token replaced by the literal 192.168.1.9; sonarr's single mount split into
two subPath mounts (assertion 6); and the prod overlay's knob deleted.

Also hardens render.py: `size` is structurally required of a bulk entry (a PV with no capacity is
rejected by the API server) but the JSON Schema only enforces `export`, so omitting it raised a bare
KeyError three frames down. It now raises a sentence naming the service, the volume and the remedy.
Found by the same perturbation pass.

Coverage: 48/51 -> 49/51 (96.1%), 2 gaps, 0 safety-critical.
BASE_REF=main make -C ci gate -> MERGE GATE: PASS.

jakman85 cac413e87a feat(cnpg): synchronous replication, quorum of 1, dataDurability preferred
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
Three instances replicating ASYNCHRONOUSLY still lose data on failover: COMMIT
returns as soon as the primary has flushed locally, so a primary that dies
before its standbys catch up takes the last few transactions with it and the
promoted standby comes up quietly missing them. On keycloak-db that is a
just-created user, a rotated credential or a consent vanishing at exactly the
moment of a failover.

`method: any` + `number: 1` makes COMMIT wait for ONE of the two standbys to
confirm — the point of having them.

dataDurability: preferred, NEVER required. `required` is a strict quorum:
fewer than `number` healthy standbys and writes BLOCK. Postgres here shares
three nodes with etcd and the CNI, so one degraded standby — a node reboot, a
Longhorn replica rebuild, a Cilium restart — would turn a partial degradation
into a total write outage, and on the SSO database that takes kubectl OIDC,
Grafana, Headlamp, Gitea and forward-auth with it. `preferred` keeps
synchronous commit while a healthy standby is there and relaxes the required
count dynamically when one is not. dataDurability is only honoured while
standbyNamesPre/standbyNamesPost are unset — both are.

NON-DISRUPTIVE: this compiles to `synchronous_standby_names`, a reload-only
PostgreSQL parameter. No pod restart, no switchover, no client disconnect.
It is the last of the three commits because it wants standbys that already
exist and are already on their final nodes.

Field shape verified against the live clusters.postgresql.cnpg.io CRD before
relying on it (CNPG 1.30.0, byte-identical schema on k3s-prod and k3s-dev):
spec.postgresql.synchronous requires `method` (enum any|first) and `number`
(x-kubernetes-validation self > 0); `dataDurability` is enum required|
preferred. None of the three Clusters previously had a `postgresql:` block,
so this adds one rather than merging into existing parameters.

DEV IMPACT: identical and non-disruptive, same reload-only path.

Verified: yamllint clean; both tiers render the block.

jakman85andClaude Opus 5 82aff4d053 feat(apps): attach the media library and the legacy Nextcloud dataset over NFS
plex, sonarr, radarr and nextcloud each gain one bulk volume. Authored in the catalog and
re-rendered, never hand-edited into apps/ (render-golden: 10/10). Layout, the export change the
operator must apply, the uid analysis and the validation probes are in docs/BULK-NFS-STORAGE.md;
everything there was measured on the host over read-only SSH, not assumed.

WHAT THE LAYOUT TURNED OUT TO BE, AND WHY IT DECIDED THE DESIGN
/mnt/Storage/plex holds movies/ tv/ photos/ AND downloads/ as SIBLINGS in one dataset — so the
arrs' import source and their libraries are one filesystem on the server, and the download client's
completed folders are already named radarr/ and tv-sonarr/. The k3s arrs are joining a tree an arr
stack has been driving for a long time.

That sibling fact is the whole argument for the arrs mounting the export ROOT rather than a
subPath per directory. Sonarr and Radarr import by hardlinking or atomically renaming, both
same-filesystem operations, and to the kernel "same filesystem" means SAME MOUNT. Two subPath
mounts of one export are two mounts: link() across them returns EXDEV regardless of what the
server knows, and the arrs do not fail loudly — they degrade to copy-then-delete, rewriting every
file over NFS and destroying the seeding copy. The smallest subtree containing both tv/ and
downloads/ IS the export root, so the root mount is the MINIMAL mount that preserves hardlinks.
Least privilege bounded below by a hard requirement. The cost is stated, not hidden: sonarr can
also write /media/movies.

  plex       /mnt/Storage/plex      -> /media                 ro   ReadOnlyMany
  sonarr     /mnt/Storage/plex      -> /media                 rw   ReadWriteMany
  radarr     /mnt/Storage/plex      -> /media                 rw   ReadWriteMany
  nextcloud  /mnt/Storage/nextcloud -> /mnt/legacy-nextcloud  ro   ReadOnlyMany  (subPath: nextcloud)

Plex is read-only because it indexes and streams; every write on that tree belongs to the arrs, and
saying so removes Plex from the set of things that can damage 8.33 T. All three media consumers use
the SAME mountPath deliberately: when qbittorrent is eventually given this export, the arrs and the
download client will already agree on absolute paths, which is the other precondition for hardlinked
imports.

*** /media AND NOT /data — A COLLISION CAUGHT WHILE RENDERING. *** The arrs' Longhorn config PVC
renders at the renderer default /data/config. A media mount at /data is mounted OVER it and MASKS
the config volume: the pod comes up with its app database shadowed by an 8 T media tree. That
discovery also exposed a SEPARATE PRE-EXISTING BUG, reported and deliberately NOT fixed here:
LinuxServer arr images run with -data=/config, so /data/config is very likely the wrong home for
that PVC and the app has been writing its EPHEMERAL layer — the exact failure catalog/plex.yaml's
mountPath comment records already having been bitten by. Plex was fixed; sonarr, radarr, qbittorrent
and jackett were not. Fixing it starts those apps from an empty config volume, so it needs its own
change with the operator present. This change does not make it worse.

UID/GID — THE FAILURE THIS TIER ALWAYS HAS
The export is sec=sys + no_root_squash, so the client's numeric uid passes through verbatim and the
server's ownership is the entire access story. The tree is 0755 owned 1000:3000, so ONLY uid 1000
can write it. LinuxServer images default to 911. Without intervention sonarr and radarr would have
mounted cleanly, gone Ready, and failed EVERY import with EACCES.

And fsGroup cannot fix that — the in-tree NFS plugin does NO ownership management, so
podSecurityContext.fsGroup is a no-op on an NFS volume. Reaching for it is how this gets
misdiagnosed. So PUID=1000/PGID=3000 are added to both arrs (PGID 3000 keeps what they write
group-readable to the live non-k3s consumers of the same export), and fsGroup: 3000 is added for
the LONGHORN config PVC only, so changing PUID does not depend on the image re-chowning /config.
plex already runs as 1000 and reads a 0755 tree; nextcloud reads as www-data. Neither needs work.

NEXTCLOUD IS MOUNTED READ-ONLY, WHICH IS A DEVIATION FROM THE BRIEF — ON EVIDENCE
The task said nextcloud writes. The dataset says otherwise: of 270 G, 267 G is config_backup/, the
rest is config/ (103 M) and config_old/ (3.4 G). There is NO data/ directory. This is the OLD
non-k3s instance's configuration plus a backup blob — an archive — and that instance is STILL LIVE
on it (exported rw to 192.168.1.6 and .5, which the operator has said must stay active). Two
Nextclouds writing one instance's config directory, each with its own database and therefore its own
oc_filecache, is unrecoverable corruption. "Do not grant more than needed" lands on ro, and ro is
the trivially reversible choice. If the intent is in fact a MIGRATION, that is a larger and more
deliberate change than a mount; the one-line flip is documented.

Read-only for nextcloud can additionally be enforced SERVER-side (only nextcloud consumes that
dataset from k3s), and the sharenfs value in the doc uses ro= for the k3s clients. The media tree
cannot: plex and the arrs may land on any node, so the server sees the same addresses for reader
and writers. Plex's ro is therefore a client-side guarantee — stated as a limitation, not left
implied.

jakman85 e8d8601ca6 feat(cnpg): required pod anti-affinity + switchover primary rolls
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
`instances: 3` alone does not keep the three instances apart. All three
Clusters used CNPG's default `podAntiAffinityType: preferred`, which is a
scheduler HINT — two instances may share a node whenever that scores better,
and they WILL on the path that matters: when CNPG recreates an instance after
a node loss, the surviving nodes are the only candidates and one of them
already runs an instance. `preferred` is how a 3-instance cluster decays back
into the single-node failure domain the previous commit exists to remove.

`required` makes it a scheduling constraint. On a 3-node cluster with no
spare, the cost is that an instance whose node is gone stays Pending until a
node returns. That is correct: a replacement squeezed onto an already-occupied
node dies with that node while making the cluster LOOK three-way replicated.
2 of 3 instances still serve and CNPG still promotes.

ALSO SETS primaryUpdateMethod: switchover. This is not cosmetic. Changing the
affinity changes the instance pod spec, so CNPG performs a rolling update, and
the CRD default for primaryUpdateMethod is `restart` (verified against the
live CNPG 1.30.0 CRD on both clusters) — a delete-and-recreate of the PRIMARY
pod, i.e. tens of seconds of no Postgres. On keycloak-db that is an SSO
outage, which also means kubectl OIDC, Grafana, Headlamp, Gitea and
forward-auth. With standbys now present, `switchover` promotes an
already-updated streaming replica instead, reducing the roll to a connection
reset. Known constraint documented in the manifest: under `switchover` the
operator rejects an update that changes imageName and a postgresql parameter
in the same reconcile.

Verified satisfiable before merge (read-only): k3s-prod and k3s-dev each have
3 Ready, schedulable, untainted nodes, and every pgdata PVC already has a
Longhorn replica on all three (replica-soft-anti-affinity=false), so any
instance can attach from any node.

DEV IMPACT: identical, and dev can absorb it. Longhorn dev nodes are 124.9 GiB
each with 152.0 GiB already scheduled under a 200% over-provisioning ceiling
(249.8 GiB); the six new 5Gi volumes add 30 GiB scheduled per node -> 182.0,
still inside the ceiling, and only ~600 MiB per volume is really consumed.
Prod is far looser: 239 -> 269 GiB scheduled against a 829 GiB ceiling.

THIS IS THE DISRUPTIVE COMMIT of the three. Land it on its own reconcile,
after the scale-out has produced two Ready standbys per Cluster, so the blast
radius is one clean switchover per database rather than a scale-out and a roll
at once. Expect a brief SSO interruption for keycloak-db.

Verified: yamllint clean; both tiers render the new fields; field names,
types and enum values checked against the live clusters.postgresql.cnpg.io
CRD (CNPG 1.30.0, identical on prod and dev).

jakman85andClaude Opus 5 2590bc4317 feat(env): BULK_NFS_SERVER — the one knob prod cannot answer yet, and why it is a placeholder
The bulk tier's PersistentVolumes need a server address, and there is no single correct one: the
two clusters sit on OPPOSITE SIDES of pfSense from the storage host, which has exactly one
interface (vmbr0 192.168.1.9/24, on pfSense's LAN).

  dev  192.168.1.40/.41/.42 — the SAME segment. Reaches it directly, and already holds one NFS
       export from it (/mnt/Storage/k8s-volumes, in the host's /etc/exports). Proven path, so
       base's default is the dev value per this file's existing convention, and dev restates it.
  prod 192.168.2.10/.11/.12 — pfSense's WAN. tcp/2049 does not traverse that today; 22 and 8006
       answer only because pfSense port-forwards them via 192.168.2.102. Opening the storage path
       is a PENDING operator decision whose two candidate outcomes give DIFFERENT values here:
       192.168.2.102 (another port-forward) or 192.168.1.9 (a route). So prod holds
       TBD-PROD-BULK-NFS-SERVER, this repo's established loud-placeholder convention.

Two findings recorded in the prod overlay because they change what the operator has to do:

  * THE EXPORT'S CLIENT LIST IS THE SAME UNDER BOTH OUTCOMES. Measured today from this
    workstation (192.168.2.132) through the existing port-forward: the storage host logged the
    connection as coming from 192.168.2.132 — a WAN-side address — not from a pfSense LAN address
    (`ss -tn` peer 192.168.2.132; the host's only route off-LAN is its default via 192.168.1.1).
    pfSense DNATs WITHOUT source NAT, so the NFS server sees prod's REAL node addresses either
    way. The `zfs set sharenfs=` work therefore does not have to wait for the routing decision.
  * ONE PORT, NOT FOUR. The PVs mount nfsvers=4.1, and NFSv4 carries mount and lock in-protocol —
    no rpcbind/111, mountd or statd. Whichever outcome is chosen, it opens tcp/2049 and nothing
    else. NFSv3 would have needed four ports, three of them on ephemeral numbers.

*** AND ONE HONEST WEAKNESS, stated in the overlay where an operator will hit it. ***
Unlike the LAN knobs above it, this placeholder does NOT fail at apply time. A PV's
spec.nfs.server is an unvalidated string: the API server accepts it, the PV is created, and the
PVC BINDS (binding is pure control-plane). The failure appears only when a pod mounts —
MountVolume.SetUp "Failed to resolve server TBD-PROD-BULK-NFS-SERVER" — so plex, sonarr, radarr
and nextcloud would sit in ContainerCreating on prod. There is no CRD validation to lean on here,
so the guard has to be procedural: set the value before prod reconciles a revision carrying the
bulk volumes. Dev renders a working value and is where these manifests are meant to be proven.

Related finding, NOT fixed here because the file does not exist on main: the static guard this
convention is supposed to lean on, `bootstrap/standup.sh`'s `s3_is_placeholder` family, is absent
from main (it lives on unmerged prod branches), so
conformance/tests/l0-static/placeholder-guard-coupling exits 3 SKIPPED and nothing in the gate
currently refuses a placeholder-shaped overlay value. When standup.sh lands, its guard needs an
arm for this knob and a consumer that calls it — assertions (2) and (3) of that check then cover
this value automatically, since the detector's SEED vocabulary already matches "TBD".

Evidence: `kubectl kustomize clusters/dev` -> BULK_NFS_SERVER: 192.168.1.9;
`kubectl kustomize clusters/prod` -> BULK_NFS_SERVER: TBD-PROD-BULK-NFS-SERVER. Both exit 0.

jakman85andClaude Opus 5 cec550045b feat(storage): the bulk tier becomes real — static NFS PVs, authored once per environment
The `bulk` class has existed since Phase 0 as a deliberate stub: the StorageClass named an NFS
CSI driver that is not installed and a server/share of REPLACE-ME, so plex, sonarr, radarr and
qbittorrent all carry a comment saying "attach the library once OQ-2 is resolved". This is that
resolution — for the case that actually exists here, which is NOT the case the stub anticipated.

The stub assumed DYNAMIC provisioning: ask a CSI driver for a bulk volume and get a fresh empty
subdirectory. That is the wrong shape for this platform's bulk data. The media library is 8.33 TiB
that already exists, on ZFS datasets on the Proxmox host, with live non-k3s consumers. Nothing
needs provisioning; existing datasets need ATTACHING. So a bulk storage entry now renders a
STATIC, pre-bound NFS PersistentVolume plus its PVC, and needs no CSI driver at all (the in-tree
NFS volume source is not deprecated and has no CSI migration).

Schema 1.4.0 adds, on a storage entry:
  export     absolute NFS export path; REQUIRED when class is bulk, FORBIDDEN otherwise (an `if`
             in the schema, so a bulk entry cannot be authored without saying what it attaches).
  subPath    mount a subtree instead of the volume root — any class.
  readOnly   any class; on bulk it also sets the PV's nfs.readOnly, so the mount really is `ro`.

The SERVER is deliberately NOT a schema field. It is the `${BULK_NFS_SERVER}` cluster-vars knob,
because dev and prod reach the SAME storage host by different addresses and R-ENV-02 says the
service definition is authored once. A ServiceDefinition says WHICH dataset; the overlay says
where the host is.

Three decisions worth the reader's time, argued in full in the r_bulk_pvs docstring:

  * PV/PVC, not an inline `nfs:` pod volume. Inline is fewer objects and would work. It cannot
    express `persistentVolumeReclaimPolicy: Retain`, which is the one property most worth having
    in git for 8.33 TiB of data with consumers outside this cluster; it puts read-only enforcement
    one Deployment edit away from silent removal; and it is invisible to `kubectl get pv,pvc`,
    which is where an operator looks for attached external storage.
  * storageClassName: "" on both ends, NOT the `bulk` StorageClass. Explicitly empty is the
    canonical marker for a statically provisioned volume. It also sidesteps a trap: a
    StorageClass's `provisioner` is IMMUTABLE, so re-pointing the deployed `bulk` stub would make
    Flux fail on that object forever.
  * Access mode is always `…Many` and follows the read/write posture — ReadOnlyMany for a reader,
    ReadWriteMany for a writer. One export is consumed by several namespaces AND several nodes at
    once, which is exactly what ReadWriteOnce cannot express; which `Many` it is then makes the
    intent legible in `kubectl get pv`.

mountOptions are a platform decision held in the renderer rather than a per-service field:
nfsvers=4.1,hard,noatime,timeo=600,retrans=2. NFSv4 carries mount and lock in-protocol, so the
only port that must be reachable is tcp/2049 — no rpcbind/111, mountd or statd. That is a
firewall decision as much as a storage one. `hard` over `soft` because a soft mount converts a
server hiccup into a short read handed to the application.

The contract doc records the trap that will otherwise be discovered in production: fsGroup is a
NO-OP on an NFS volume (the in-tree plugin does no ownership management), so a writable bulk mount
requires the container's own uid/gid to suit the export's ownership. A mount that succeeds and
then cannot write is this tier's characteristic failure.

Every pre-existing golden renders byte-identical: the new keys are emitted only when declared, and
`readOnly` defaults to False. render-golden: 10/10. selftest: PASS.

jakman85 f338e91770 feat(cnpg): instances 3 on all three Clusters — a standby to fail over to
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
All three CNPG Clusters ran `instances: 1`. Longhorn's 3-way replication
saves the DATA when a node dies; it does not save the SERVICE — a single
instance has to be rescheduled, re-attach its volume and replay WAL before
Postgres accepts a connection again.

With nothing in the spec keeping them apart, all three primaries had drifted
onto ONE node (k3s-prod-2 on prod, k3s-dev-3 on dev). On 2026-09-07 that node
took SSO, Nextcloud and Semaphore down together, and with SSO went kubectl
OIDC, Grafana, Headlamp, Gitea and forward-auth.

Three instances give each Cluster a streaming standby CNPG can promote in
seconds, repointing the -rw Service with no volume re-attach and no restore.

UNBLOCKED BY WORKING BACKUPS, NOT A SUBSTITUTE FOR THEM. Standbys replicate
corruption and deletions faithfully; only the Barman archive is a backup, and
adding standbys while archive_mode=on with a failing archive_command would
have multiplied the disk-full clock, not hedged it. All three Clusters on
both k3s-prod and k3s-dev now report ContinuousArchiving=True with a real
firstRecoverabilityPoint (verified read-only, 2026-09-07).

Scaling out is non-disruptive on its own: CNPG creates -2 then -3
sequentially, each seeded by pg_basebackup from the RUNNING primary. The
primary is not restarted and clients are not disconnected. The anti-affinity
change that DOES cause a switchover is deliberately the next commit.

DEV IMPACT: identical — dev is on the same shape (three single-instance DBs,
all on k3s-dev-3) and gets the same scale-out. Dev has three untainted nodes
and Longhorn headroom for it (see the next commit's message for the numbers).

Cost: 2 extra 5Gi PVCs per Cluster; ~30 GiB provisioned cluster-wide against
live pgdata of ~600 MiB each, on Longhorn with 200% over-provisioning.

Verified: yamllint clean; `kubectl kustomize --load-restrictor
LoadRestrictionsNone platform-config` and `kubectl kustomize apps/wave-0`
both render `instances: 3`.

jakman85 e319777849 docs(pm): draft the R-ENV-03 amendment, and name the gate hole that hid it
The requirement's literal reading ("no prod-specific artifact in a shared path")
forbids the environment-selected PAIR that R-ENV-02 prescribes for a value that
must differ per environment while the manifests stay identical — and a Secret's
difference cannot live in cluster-vars, because it is ciphertext in a SOPS file.
Drafted wording that keeps the guard's teeth (an artifact only prod APPLIES
still fails) and removes the false positive, for the System Architect: the spec
repo is read-only here and CI-gated by R-TEST-06.

Also recorded, checked rather than assumed: the merge that turned R-ENV-03 red
was gated with a touched-requirement subset that never selected R-ENV-03, so
ci/l0.sh Stage 3b filtered the already-red check out of the run that printed
PASS. Replaying that delivery's twelve paths through
fix/touched-requirements-fail-closed's requirement-paths.map still yields no
R-ENV-03, so landing that branch would NOT have caught this. The two changes
that would (unconditional whole-repo L0 stages; a changed conformance test
attributing its own requirement labels) are ci/ work and are left to that
branch, not smuggled in here.

jakman85 730d12ddc4 fix(conformance): R-ENV-03 shared-path rule tests the harm, not the filename
The blanket regex around RENDERED_DIRS failed any tracked file whose name
carries a delimited `prod` token. That caught the four per-environment backup
credential halves (BACKUP_CREDENTIALS_SUFFIX) even though BOTH halves are
applied to BOTH clusters as base resources and the overlay selects only which
one the shared consumer REFERENCES — i.e. exactly the R-ENV-02 contract the
regex exists to protect. Renaming the files to dodge the regex was rejected as
gaming the guard, so the rule now encodes the property instead.

The fix is not an allowlist of those four paths. A prod-token file in a shared
path is excused only when the tree proves all of:

  (A) it declares nothing but Secrets whose names end in the environment suffix
  (1) its own directory's kustomization applies it, and EVERY environment value
      of the selector resolves to a Secret that some resource of that same
      kustomization declares, in the same namespace
  (2) nothing names the suffixed Secret — or the suffixed file — literally;
      every reference is `<base-name>${VAR}`
  (3) that VAR is defined for the base and for every overlay, and prod's value
      is the one that selects this file

References are read from parsed YAML values, never raw text: the mechanism is
spelled out by name in comments beside the resources, and a comment references
nothing.

No other assertion is weakened; the check still runs 96 assertions, and the
pass output now notes each excused file and why.

jakman85andClaude Opus 5 df1d2ab44d docs(prod): node 1's drive was replaced — and §2's exit condition still is not met
Records the 2026-09-07 I/O-starvation incident and the drive swap: the C400 was
replaced with a Samsung 850 EVO, and under the same load class (an active
18-replica Longhorn rebuild, with node 1 as the write target) I/O pressure fell
from full avg300 11.36 to 3.79 — from ~4x worse than its peers into node 3's band.

Updates the three §0 cells that had become false (disk model, drive health, kernel
— all three nodes now run 7.1.8, not 6.12) and adds §0c rather than rewriting the
'NOT hardware-symmetric' analysis, which is still the correct reasoning about the
state it described.

Two things the rebuild taught, recorded so the next one is cheaper: Longhorn
refuses a replaced disk with DiskFilesystemChanged and needs disable -> remove ->
re-add in that order, and the inventory's [k3s_prod_primary] decides BOTH
--cluster-init and k3s_api_host, so rebuilding the founder without moving that
designation would have founded a second cluster.

The replacement does NOT close §2: etcd and Longhorn still share one SATA spindle.

jakman85andClaude Opus 5 69a25cff82 fix(node_health): say 'active via <unit>', not a bare parenthetical

jakman85andClaude Opus 5 c1e36d9353 docs(node_baseline): say why the Longhorn claim guard's swap list is now always empty
The claim guard builds node_baseline_lh_protected_devices from ansible_mounts plus
`swapon --show`. With swap.target masked, a baselined node has no active swap, so
that half of the list contributes nothing — which reads like a guard that quietly
stopped guarding. It is not: the claim candidate comes from whatever is mounted at
node_baseline_longhorn_claim_mountpoint, and a swap partition is neither mounted nor
ext4, so it could never be the candidate. Say so where the next reader will ask.

jakman85andClaude Opus 5 9d00a3fcd3 fix(node_health): memory.swap blamed the wrong thing, and could not see the defect
The WARN read "roles/node_baseline runs swapoff and neutralises the fstab entry;
this node has not been baselined yet". That was a MIS-DIAGNOSIS. All three prod
nodes HAD been baselined, had their fstab swap line commented out by the role, and
were still swapping 977 MiB each after a reboot. Anyone reading that WARN would
have re-run the role that had already run, and watched swap come back next boot.

The detail now names the actual mechanism — systemd-gpt-auto-generator re-creating
a .swap unit from the partition TYPE GUID 0657fd6d-a4ab-43c4-84e5-0933c84b4f4f at
every boot, without reading /etc/fstab — says in as many words that this is not
"the node has not been baselined", and points at `node-baseline.yml --tags system`.

The check was also blind in the other direction: SwapTotal == 0 is not evidence
that swap is disabled, only that nothing has been swapped on yet this boot, so a
node freshly swapoff-ed PASSed while still set to swap again on reboot — exactly
the state the old role left behind. The collector now reports memory.swap_persistence
(swap.target masked?, .swap units the generators emitted this boot, which of them
are masked, leftover active fstab swap lines — all world-readable, no root, no
systemctl parsing), and the check WARNs on "clean now, swapping after the next
reboot".

Rendered against every fact shape (swap active + unmasked, swap off + unmasked,
after the fix, a dev VM with no swap partition at all, per-unit mask only,
persistence unreadable, an older collector's output with the key absent, and
/proc/meminfo unreadable) and verified live on k3s-prod-1 post-reboot:
  [PASS] memory.swap — no swap active and none can be activated: swap.target is masked

jakman85andClaude Opus 5 0e92d258dd fix(node_baseline): swap-off now survives a reboot — mask swap.target
The role's `swapoff -a` + commented fstab line held only until the next boot,
on every prod node. Measured 2026-09-07: all three came back from a reboot with
977 MiB of swap ACTIVE (k3s-prod-1 /dev/sda4, k3s-prod-3 /dev/sda4, k3s-prod-2
/dev/nvme0n1p4) while their fstab swap entry was commented out by this role. The
role reported success and the setting silently expired.

CAUSE. systemd-gpt-auto-generator claims any GPT partition typed
0657fd6d-a4ab-43c4-84e5-0933c84b4f4f ("Linux swap") from the PARTITION TABLE,
synthesises a .swap unit into /run/systemd/generator.late/ and links it into
swap.target.wants/. It never reads /etc/fstab, so neutralising fstab cannot stop
it. Re-running the generator by hand on k3s-prod-1 says so verbatim:
  Probed fstype 'swap' on partition /dev/disk/by-diskseq/1-part4.
  Adding swap: /dev/disk/by-diskseq/1-part4

MECHANISM. Mask swap.target. `systemctl show` on the generated unit says its only
inbound dependency is `WantedBy=swap.target` — Requires/RequiredBy/BoundBy empty,
and the matching .device unit has an empty Wants=, so a device appearing does not
pull its swap unit in by itself. swap.target is the single choke point for every
activation path: gpt-auto, systemd-fstab-generator, systemd-cryptsetup-generator.
It is device-shape independent (no device name appears in the change, so one task
covers sda4, nvme0n1p4 and dev's vda VMs), boot-safe (swap.target is Wants=/After=
from sysinit.target and After= from tmp.mount; RequiredBy= is EMPTY on all three
prod and all three dev nodes, and a masked unit reached only via Wants= is skipped,
not failed), and inert if the device is absent or renamed. The generated units are
masked too, as a second independent barrier.

Rejected: `systemd.gpt_auto=0` (disables GPT auto-discovery wholesale, needs a GRUB
edit + reboot to become true, and on DEV would switch off root auto-discovery — dev's
vda1 carries the discoverable GUID 4f68bce3-e8cd-4db1-96e7-fbcaf984b709); clearing
the partition's GPT type GUID (a partition-table write to the live boot disk of a node
serving etcd and Longhorn replicas, and an irreversible decision about that 977 MiB
that belongs to the operator); `systemd.swap=0` (systemd-fstab-generator only — this
swap does not come from fstab).

`swapoff -a` is now conditional on `swapon --show` returning something, so the task
reports honestly instead of hiding a command that ran anyway behind changed_when: false.

PROVEN on k3s-prod-1 (all 18 Longhorn volumes healthy before the reboot):
  run 1 changed=2, run 2 changed=0
  after `reboot`: /proc/swaps empty, `free` Swap 0B, swap.target masked, the
  generated unit still emitted by the generator and still masked, `systemctl
  --failed` empty, `systemctl is-system-running` = running.

jakman85andClaude Opus 5 08fbe85638 fix(ansible): move the founder designation to node 2
Node 1's SSD failed and was replaced; Debian was reinstalled, so node 1 is now a
JOINING node with no cluster state. It was still listed in [k3s_prod_primary],
and that group decides two things at once:

  1. which play gets k3s_server_mode: primary -> --cluster-init, which FOUNDS A
     NEW CLUSTER, and
  2. what k3s_api_host resolves to -- the --server join target.

So re-provisioning node 1 unchanged would have pointed a rebuilt, empty node at
ITSELF and founded a second cluster beside the live one. The role's
`creates: /etc/rancher/k3s/k3s.yaml` guard does not help: on a fresh install that
file is absent, so cluster-init WOULD have run.

Node 2 is the senior surviving server (up since 2026-09-01) and takes the founder
slot. Its own cluster-init task is inert precisely because k3s.yaml already exists
there. Verified after the change: k3s_api_host renders 192.168.2.11, and
groups[k3s_primary_group][0] is k3s-prod-2.

This is a latent gap the role documented but did not handle -- its comment assumes
the founder is always alive ('On a WARM single-node rejoin the founder is up and
answering too'). Rebuilding the founder itself was not covered.

jakman85 863af01062 docs: the §2 shared-device measurement came back, and it does not hold
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
infra/PROD-PROVISIONING.md §2 recorded the etcd/Longhorn shared-partition risk as
"accepted to be MEASURED, not assumed", with an exit condition. The measurement
arrived on 2026-09-07 in production, 2 d 7 h after bring-up, as an outage.

§2 now carries "THE MEASUREMENT CAME BACK": the journal evidence, the three-node
IO PSI table (11.36 / 0.75 / 1.29), and the honest verdict that the section's own
premise — "every prod node is SSD or NVMe, where rebuild I/O costs latency rather
than collapsing it" — was right about node 2 and wrong about node 1. A 2011 C400
with 61,440 reallocated sectors and no power-loss protection is not the "SSD" that
reasoning assumed, and §0 had already named the three-way drive asymmetry as the
fault line. The exit condition is OPEN and the second bullet (dedicated device)
applies; that remains the operator's.

Also records what the three software mitigations in this branch do and do not buy,
including the point that no cgroup or scheduler control arbitrates the ext4 journal
both tenants share — and the gap that etcd's own fsync histograms, which the exit
condition literally asks for, are not collected because kubeEtcd is disabled for
k3s. PSI is the signal that exists.

DECISIONS-LOG gains the full entry: the four I/O mechanisms found INERT on these
nodes (IOSchedulingClass, IOSchedulingPriority, io.latency, bare IOWeight), the
finding that concurrentReplicaRebuildPerNodeLimit was already set and already held
during the outage, the third instance of config that looked applied and was not
(orphanAutoDeletion), and the three things still requiring the operator.

infra/ansible/README.md: CORRECTED a stale claim that k3s-prod-2/-3 "stay commented
out" of the inventory. They have been live in [k3s_prod_secondary] since
2026-09-03. That sentence is exactly the kind used to reason about blast radius —
`-e k3s_hosts=k3s_prod` targets THREE hosts, not one — so it is replaced with the
--list-hosts command that settles it. The new etcd-io-priority play is added to the
run order, the layer table and the prod command list.

jakman85 f7a9229d81 fix(ansible): the NVMe node would have died on an undefined variable
Self-review of the role I had just written. On k3s-prod-2 the scheduler path is
deliberately skipped, so the `stat` on /sys/fs/cgroup/system.slice/k3s.service is
skipped too — and a SKIPPED registration has no `.stat` key at all. Ansible
templates `loop:` BEFORE it evaluates `when:`, so

    loop: "{{ ['system.slice'] + (['system.slice/k3s.service']
              if _eio_k3s_cgroup.stat.exists else []) }}"

raises on that host even though the task would never have run. The role would have
failed on the one node it is designed to leave alone — and it would have failed at
the very end, after doing nothing, which reads like a broken mitigation rather than
an intentional skip.

`| default(false)` on both uses. Exercised offline against a simulated skipped
registration; `--syntax-check` re-run.

2026-09-07 02:46:26 -05:00
jakman85 a819c50ffe feat(ansible): arbitrate the shared etcd/Longhorn device — and prove it landed
roles/etcd_io_priority + playbooks/etcd-io-priority.yml, enabled for [k3s_prod]
only. Mitigation for the 2026-09-07 k3s-prod-1 outage: etcd's WAL fdatasync took
3.4-6.7 s (expects 1 s), the node went NotReady while the host stayed up, and
/proc/pressure/io full avg300 read 11.36 there against 0.75 (node 2, NVMe) and
1.29 (node 3).

WHAT IT DOES, on the SATA nodes only:

  1. k3s-etcd-io-priority.service (oneshot, Before=k3s.service) switches the
     shared device to BFQ and drops nr_requests 64 -> 32.
  2. IOWeight=10000 drop-ins on system.slice AND k3s.service, which BFQ turns
     into io.bfq.weight=1000 — a 10:1 share against the default-weighted
     kubepods.slice where Longhorn's instance-managers live.
  3. Reads all of it back out of the kernel and ASSERTS. If the scheduler did
     not switch or the weight did not land, the play fails.

THE THREE OBVIOUS ANSWERS ARE INERT ON THESE NODES, ALL CHECKED LIVE, ALL
DELIBERATELY ABSENT:

  * IOSchedulingClass=realtime on k3s.service. mq-deadline DOES honour the
    priority class, so this looks right — but ioprio is inherited across fork
    and kept across exec (block/blk-ioc.c __copy_io copies ioc->ioprio) and
    CONTAINERD IS A CHILD OF THE K3S SERVER PROCESS. Verified on k3s-prod-1:
    containerd pid 84553 has ppid 84333 = k3s-server, and
      ionice -c2 -n0 -- sh -c 'ionice -p $$; sh -c "ionice -p \$\$"'
    prints best-effort prio 0 at both levels. Realtime for k3s is realtime for
    every container on the node, Longhorn included. No relative gain.
  * IOSchedulingPriority (the level inside a class): mq-deadline buckets by
    CLASS only, so BE-0 vs BE-4 is a no-op.
  * io.latency, which would be the ideal scheduler-independent protection:
    CONFIG_BLK_CGROUP_IOLATENCY is not built in Debian trixie's 7.1.8 kernel
    (only IOCOST is) and no io.latency file exists under /sys/fs/cgroup.

AND ONE NON-OBVIOUS TRAP: bare IOWeight= is DECORATION here. systemd writes it
to io.weight (blk-iocost — compiled in but disabled, io.cost.qos is empty) and
io.bfq.weight (BFQ — not loaded). Neither reader exists on the stock nodes, so
the scheduler change and the weights have to be one role with one verification.
The value is 10000 rather than a "reasonable" 1000 for the same reason: systemd
rescales 1..10000 onto io.bfq.weight's 1..1000, so 1000 maps to ~101 against
BFQ's unweighted default of 100. The role asserts the result is >= 500.

k3s-prod-2 IS SKIPPED ON PURPOSE. The role discovers the device under
k3s_data_dir per node (verified: prod-1/3 -> /dev/sda5 -> sda, prod-2 ->
/dev/nvme0n1p5 -> nvme0n1) and writes NOTHING on NVMe rather than leaving inert
files behind — BFQ is a poor fit for NVMe and node 2 measured 0.75 IO PSI.

DEV IS UNTOUCHED. Master switch defaults false and is set true only in
group_vars/k3s_prod; dev has a dedicated etcd device (docs/plans/ssd-etcd-
isolation.md) and nothing to arbitrate. Verified with --list-hosts: no extra
vars -> the three dev hosts (where the role is a no-op); -e k3s_hosts=k3s_prod
-> the three prod hosts; --limit k3s-prod-3 -> one.

NOTHING IS RESTARTED. The oneshot writes two sysfs files; the weights go in
through daemon-reload. If daemon-reload turns out not to re-realize a running
k3s.service's cgroup, the verification FAILS and names the rolling restart as
the fix rather than quietly leaving the weight unapplied.

WHAT IT CANNOT DO, stated in the role README and worth repeating: it does not
separate the two tenants. Both still write one ext4 filesystem, and no cgroup
control arbitrates the shared jbd2 journal that etcd's fdatasync waits on. It is
also UNPROVEN on this hardware — it fails loudly if the settings do not land, it
cannot tell you they helped. Apply to k3s-prod-3 first and watch
NodeIOPressureHigh. Replacing the C400 / giving etcd its own device remains the
real fix and the operator's (PROD-PROVISIONING.md §2 exit condition).

Syntax-checked, and the fact-derivation and assert expressions were exercised
offline against all three node shapes plus negative controls (a node still on
mq-deadline fails the gate; IOWeight=1000 -> 101 fails the floor).

jakman85 efc6db6c1f feat(obs): alert on I/O pressure — the metric that missed the prod-1 outage
On 2026-09-07 06:05:21Z k3s-prod-1 went NotReady ("Kubelet stopped posting node
status") with the host up, pingable and SSH-able. The cause was disk I/O
starvation of the embedded etcd, from its own journal:

  slow fdatasync               took=3.56s / 6.71s / 4.95s / 3.40s (expects 1s)
  apply request took too long  took=8.30s                         (expects 100ms)
  etcdserver: too many requests

/proc/pressure/io FULL avg300 read 11.36 on k3s-prod-1 against 0.75 on
k3s-prod-2 (NVMe) and 1.29 on k3s-prod-3 — all three nodes put /data/k3s
(etcd's WAL) and /data/longhorn (every replica) on ONE partition, and node 1's
is a 2011 consumer SATA SSD with 61,440 reallocated sectors.

The stack alerted on CPU-PSI and memory and had NO I/O alert at all, so the
first signal the operator got was a node already out of the cluster. Adds:

  NodeIOPressureHigh      full IO PSI > 5%  for 10m  warning
  NodeIOPressureCritical  full IO PSI > 10% for 5m   critical

Thresholds are measured, not guessed: rate() is a 0-1 fraction, so the outage's
11.36% is 0.1136 and the healthy steady state on the same node is ~0.01.
Verified live that node-exporter already exports
node_pressure_io_{stalled,waiting}_seconds_total for all three prod nodes, so
these rules fire on arrival — no new exporter, no scrape change. (etcd's own
fsync histograms are NOT available: kube-prometheus-stack's kubeEtcd scrape job
is deliberately disabled for k3s, so PSI is the signal we actually have.)

PSI *full* (every runnable task blocked on disk), not *some*: `some` is noisy on
a storage node and did not separate the failing node from its peers.

Dashboard gains the matching I/O row and is retitled accordingly. Not scoped to
prod — dev shares this file and its k3s VMs are HDD-backed, where the same alert
is if anything more likely to earn its keep.

gate / gate (push) Has been cancelled

Shipped in the previous delivery and failing on every run since:

  FATAL: cannot read /etc/keycloak-realm-clients (PermissionError)
  BackoffLimitExceeded

The client-secrets volume used defaultMode 0400 — owner-only — but the owner of a
projected Secret volume is root, while the pod runs runAsUser/runAsGroup 65532.
The sibling script volume worked only because it is 0444. So the healer that
exists to correct client-secret drift was itself inert.

It failed CLOSED (no writes attempted, no drift introduced), and the two alerts
shipped alongside it are exactly what surfaces this: KeycloakClientSecretReconciler
Failing fires on the failed Jobs. The observability caught its own subject.

Fixed with fsGroup 65532 + defaultMode 0440 rather than relaxing to world-readable
0444: fsGroup makes the projected volume group-owned by the running user, so the
secret stays unreadable to any other uid in the container.

jakman85andClaude Opus 5 6548f9a89c fix(semaphore): per-environment OIDC URLs — same latent break as Headlamp
Semaphore's whole SEMAPHORE_OIDC_PROVIDERS JSON blob lived inside the SOPS-encrypted
semaphore-bootstrap Secret (key `oidc-providers-json`) because it CONTAINS the confidential
client secret. That buried two environment-specific, NON-SECRET URLs in ciphertext —
provider_url (the realm issuer) and redirect_url — where Flux's ${BASE_DOMAIN} postBuild
substitution cannot reach. Both were frozen at `home.keithjackson.dev`, so prod's Semaphore
was pointed at dev's Keycloak and dev's own redirect URI: identical root cause to the
Headlamp login timeout, not yet reported only because nobody had tried prod SSO.

FIX: split the blob. The URLs are public and now live as a plaintext literal in
catalog/semaphore.yaml (rendered to the apps/wave-1 golden), ${BASE_DOMAIN}-substituted like
every other hostname. Only the client secret stays encrypted, in its own key
`oidc-client-secret`, and the KUBELET splices it back via dependent-env-var expansion:
$(SEMAPHORE_OIDC_CLIENT_SECRET) resolves against the secretKeyRef env var declared
immediately above it (order is load-bearing — the kubelet resolves env in list order and
leaves a forward reference as literal text).

Verified: the new key holds the same value as keycloak-realm-clients/semaphore-client-secret
(the mirror invariant), Semaphore v2.19.10's util.OidcProvider consumes client_secret as
before, and `flux envsubst --strict` leaves $(...) untouched while resolving ${BASE_DOMAIN} —
dev renders keycloak.home.keithjackson.dev, prod keycloak.prod.home.keithjackson.dev.

apps/wave-1/semaphore.yaml is a render golden; regenerated with the canonical
`catalog/render.py --all catalog -o apps --wave-layout --no-image-automation`.

jakman85andClaude Opus 5 bfa39bc5d0 fix(headlamp): per-environment OIDC URLs — prod was dialing DEV's Keycloak
The operator could not log in to Headlamp on prod:

  Get "https://keycloak.home.keithjackson.dev/realms/homelab/.well-known/openid-configuration":
  dial tcp 192.168.1.53:443: i/o timeout

ROOT CAUSE: OIDC_ISSUER_URL and OIDC_CALLBACK_URL were keys INSIDE the SOPS-encrypted
headlamp-oidc-credentials.sops.yaml. Flux's ${BASE_DOMAIN} postBuild substitution rewrites
the RENDERED manifest text and can never reach inside ciphertext, so both values were frozen
at the apex `home.keithjackson.dev` in BOTH environments. Dev IS the apex, so dev looked
correct; prod (BASE_DOMAIN = prod.home.keithjackson.dev) therefore pointed at dev's Keycloak
at 192.168.1.53 — on the dev LAN behind pfSense, unroutable from prod's 192.168.2.0/24.

FIX: an issuer URL and a callback URL are PUBLIC. Move both out of the Secret into the
HelmRelease's spec.values.env, written with ${BASE_DOMAIN} so substitution resolves them per
environment. The Secret keeps only what is genuinely secret or environment-invariant
(OIDC_CLIENT_SECRET, OIDC_CLIENT_ID, OIDC_SCOPES).

Exactly ONE source per variable: the chart renders `env:` after `envFrom:`, and an explicit
env entry silently WINS over the same name from envFrom — so the two sets must not overlap,
and they no longer do. The five load-bearing names the chart's $(...) args require
(OIDC_CLIENT_ID/CLIENT_SECRET/ISSUER_URL/SCOPES/CALLBACK_URL) are all still delivered;
verified by rendering platform/headlamp per overlay, `flux envsubst --strict`, and
`helm template` of chart 0.41.0 against the substituted values.

Side effect, deliberate: naming OIDC_CALLBACK_URL in `env:` makes the chart finally EMIT
`-oidc-callback-url=$(OIDC_CALLBACK_URL)` — it gates that arg on the value being set via
`env:`/`config.oidc`, which a Secret key alone never tripped, so the Secret's callback URL
had been dead weight. The value is byte-identical to the single redirectUri registered on the
Keycloak `headlamp` client (also ${BASE_DOMAIN}-templated), the only URI Keycloak accepts.

[parity] holds: prod's kube-apiserver oidc-issuer-url is an install-time k3s flag from
k3s_base_domain=prod.home.keithjackson.dev, which is exactly what Headlamp now uses.

jakman85andClaude Opus 5 708a05dfc1 fix(devcontainer): restore multi-cluster kubeconfig selection
infra/devcontainer/kubeconfig.sh was never staged into the delivery-A commit, so
the branch built on main carried main's single-cluster tooling and `--context
k3s-prod` failed with 'context does not exist' mid-incident. Not Flux-reconciled,
so it never affected the cluster — but it breaks prod diagnosis from a checkout of
this branch, which is when you need it most.

Carries the concurrency fix: the merged kubeconfig holds both contexts and NO
current-context, with each invocation getting a per-invocation selector file
prepended to KUBECONFIG. Two concurrent dev.sh runs with different CLUSTER values
previously overwrote each other's current-context mid-command — reproduced live,
a CLUSTER=dev reader returned k3s-prod nodes on 3 of 7 iterations.

jakman85andClaude Opus 5 161430d915 feat(backup): the overlay picks the credential — BACKUP_CREDENTIALS_SUFFIX
The previous commit created the two halves. This one wires the choice, so dev renders MinIO
credentials and prod renders R2 credentials from the SAME base manifests (R-ENV-02: the
overlay patch is the entire difference between environments; no base manifest is forked).

    cluster-vars  BACKUP_CREDENTIALS_SUFFIX   base ""  |  dev ""  |  prod "-prod"

    velero HelmRelease  credentials.existingSecret: velero-cloud-credentials${BACKUP_CREDENTIALS_SUFFIX}
    3x CNPG Cluster     s3Credentials.*.name:      <db>-backup-credentials${BACKUP_CREDENTIALS_SUFFIX}

ONE SUFFIX, NOT FOUR SECRET-NAME KNOBS. Four independent knobs can be updated three-quarters
of the way, leaving one consumer reading the OTHER environment's key with nothing rendering
wrong — and StrictPostBuildSubstitutions cannot catch that: strict mode fails on an UNDEFINED
variable, never on a defined-but-stale one. With one suffix the four move together or not at
all. The cost is that the rendered Secret name is not greppable from the consumer, so both
kustomizations spell the two names out in full beside the resources.

THE BASE DEFAULT IS "" AND THAT IS LOAD-BEARING. It renders the UNSUFFIXED names — objects
that exist in every render, and that dev is running today. The alternative failure mode is
strictly worse than the shared-Secret state this replaces: velero's pod hangs in
ContainerCreating forever when `existingSecret` names a missing Secret (the volume never
mounts), and a CNPG Cluster whose s3Credentials Secret is absent stops archiving WAL — which
under archive_mode=on is a filling pgdata PVC, not a missing backup. So an unresolvable
default breaks the referencing cluster HARDER than a wrong key does. Both overlays state the
value explicitly anyway, so neither inherits it silently.

Prod's overlay change is a cluster-vars op only. The velero Flux Kustomization patch is
untouched (it stays decryption-only, and velero stays suspended on prod).

VERIFIED — `kubectl kustomize --load-restrictor LoadRestrictionsNone` on clusters/dev and
clusters/prod for the cluster-vars values, then on each of the four affected tiers (platform,
platform-config, platform/velero, apps/wave-0) piped through `flux envsubst --strict` with
that environment's variables:

  strict envsubst              PASSES for all 8 (env x tier) combinations
  dev   velero existingSecret  velero-cloud-credentials
  dev   keycloak/nextcloud/semaphore-db  <db>-backup-credentials         (both key refs each)
  prod  velero existingSecret  velero-cloud-credentials-prod
  prod  keycloak/nextcloud/semaphore-db  <db>-backup-credentials-prod    (both key refs each)
  both  all EIGHT Secret objects present in the rendered output (dev and prod alike)
  no `${...}` survives in any rendered tier except gitea's three DELIBERATE `$${...}` shell
    escapes in apps/wave-0, which are pre-existing and unrelated.

Read alongside the endpoints the same overlays already set, the two environments are now
isolated on credential AND target:
  dev   velero s3://velero (root) + cnpg s3://cnpg      @ http://192.168.1.9:9000  region us-east-1
  prod  velero k3s-prod-backup/velero + barman prefix   @ https://<acct>.r2.cloudflarestorage.com  region auto

jakman85andClaude Opus 5 e7c4a95c2d feat(backup): the four backup credentials become TWO objects each, one per environment
The four backup-credential SOPS Secrets are SHARED BASE manifests: platform/ and apps/ are
rendered by the same Flux tiers on both clusters, and the ONLY per-environment difference in
this repo is cluster-vars substitution (R-ENV-02). So writing the R2 token into all four
(0a6a862) did not "give prod credentials" — it REPLACED DEV'S. Merging that as-is would have
handed dev's Velero and all three dev CNPG Clusters an R2 key id to sign MinIO requests with:
403 on every WAL segment, and archive_mode=on turns that into a disk-full clock on the pgdata
PVC, not a degraded backup. Dev's PROVEN DR restore (R-STATE-03) is the thing that would have
broken.

This commit splits the material. Each credential is now TWO Secret objects, both applied to
BOTH clusters, differing only in name suffix:

    dev  -> velero-cloud-credentials              keycloak/nextcloud/semaphore-db-backup-credentials
    prod -> velero-cloud-credentials-prod         ...-db-backup-credentials-prod

The consumer picks one by name; that wiring is the NEXT commit, so this one changes no
rendered reference and is a no-op for both live clusters.

WHY DEV KEEPS THE UNSUFFIXED NAME. Dev is live. Renaming its Secret would change
`s3Credentials.accessKeyId.name` on three running CNPG Clusters — which projects into the
instance pods' environment and therefore ROLLS keycloak-db, nextcloud-db and semaphore-db —
and would roll the velero Deployment, all to rename an object whose contents do not change.
This repo already makes exactly this call for dev's live identifiers (EXTERNALDNS_TXT_OWNER_ID
"default", VELERO_BACKUP_PREFIX ""): the live cluster keeps the name it is running, and the
NEW environment takes the new one. The asymmetry is deliberate and documented at each
kustomization.

WHERE THE MATERIAL CAME FROM. Neither side is invented:
  - the four unsuffixed files are restored byte-for-byte from `main` (the MinIO material as
    it stood before 0a6a862), so dev's Secrets are IDENTICAL to what dev is running;
  - the four `-prod` files carry the R2 token from 0a6a862 (already on this branch as
    9739e9b), re-encrypted only because metadata.name changed.

RE-ENCRYPTION, AND WHY A COPY+SED IS NOT ENOUGH. `.sops.yaml` sets
`encrypted_regex: ^(data|stringData)$`, so metadata.name stays cleartext — but SOPS MACs the
WHOLE document (there is no `mac_only_encrypted` here), so editing that cleartext line
invalidates the MAC and `sops -d` then refuses the file. The `-prod` files were therefore
produced inside the dev toolbox (infra/devcontainer, which has sops 3.9.4 and the age key
mounted) by decrypt -> rename -> re-encrypt, with the plaintext never leaving a container
tmpfile. Note for the next person: `sops -e --output NEW OLD` matches creation rules against
the INPUT path, so encrypting a tmpfile into a repo path needs `--filename-override NEW` or
it dies with "no matching creation rules found".

Verified: all eight files `sops -d` cleanly; the four dev files hash to dev's material and the
four prod files to R2's, and the two sets differ. `.sops.yaml` needed no new rule — the
existing `(platform|apps|catalog)/.*(secret|sops)\.ya?ml$` rule already matches
`*-prod.sops.yaml`, so the new files encrypt to the same age recipient.

apps/wave-0/kustomization.yaml is GENERATED, so render.py learns the `-prod` sidecar rather
than the golden being hand-edited: `<db>-backup-credentials-prod.sops.yaml` now places into
the DB's wave alongside its unsuffixed twin (both must exist before the Cluster that names
one), and the selftest asserts it.

jakman85andClaude Opus 5 0a0527e7db feat(backup): prod's off-cluster DR lands on R2 — and stops the WAL clock
Prod has been archiving WAL to `TBD-PROD-S3-BACKUP-ENDPOINT` since bootstrap.
Verified live 2026-09-07 on all three CNPG Clusters: ContinuousArchiving=False,
"unexpected failure invoking barman-cloud-wal-archive: exit status 4". Because
archive_mode is ON, that is not a degraded backup — it is a DISK-FULL CLOCK.
Postgres will not recycle a segment it has not archived, so keycloak-db's pgdata
PVC is at 579 MiB used / 4360 MiB free and climbing monotonically. When it fills,
the primary PANICs and takes SSO down, and with it kubectl OIDC, Grafana,
Headlamp, Gitea and forward-auth. Wiring the endpoint is what lets Postgres drain
the whole accumulated backlog in one pass.

THE KNOB LAYOUT (three new, one repurposed) and why it is shaped this way.

The operator created exactly ONE R2 bucket, `k3s-prod-backup`, but the two backup
tools want differently-SHAPED values: the Velero chart takes `bucket` and `prefix`
as separate fields, while CNPG's barmanObjectStore.destinationPath is one full
s3:// URL whose first path segment IS the bucket. So:

  S3_BACKUP_ENDPOINT     dev http://192.168.1.9:9000   prod https://<acct>.r2...
  S3_BACKUP_REGION       dev us-east-1                 prod auto
  VELERO_BACKUP_BUCKET   dev velero                    prod k3s-prod-backup
  VELERO_BACKUP_PREFIX   dev ""                        prod velero
  CNPG_BACKUP_PATH       dev s3://cnpg                 prod s3://k3s-prod-backup/barman

There is deliberately NO separate `S3_BACKUP_BUCKET`: CNPG's bucket already lives
inside CNPG_BACKUP_PATH, and a second knob holding the same bucket name twice is a
rotation waiting to drift. Three knobs, each shaped for its own consumer, and no
two of them can contradict each other.

TENANCY. Inside k3s-prod-backup, velero and barman get disjoint TOP-LEVEL
prefixes — s3://k3s-prod-backup/velero/ and s3://k3s-prod-backup/barman/<cluster>/
— with the bucket ROOT left empty so a misrendered prefix lands somewhere
obviously wrong instead of silently colliding. This is not tidiness: Velero ADOPTS
every backup under its location and TTL-DELETES it on retention, so an overlapping
prefix would let it reap WAL segments; and interleaving two Postgres servers' WAL
into one prefix corrupts the chain outright. Dev↔prod isolation is doubly
independent — different endpoint AND different bucket names — so neither cluster
can reach the other's objects even with a mis-substituted prefix.

DEV IS UNCHANGED, BYTE-FOR-BYTE, and that is asserted rather than assumed. Base
defaults are dev's LIVE values (verified against the running cluster: BSL
bucket=velero with NO prefix, region us-east-1; all three CNPG Clusters
ContinuousArchiving=True at s3://cnpg on the MinIO), and the dev overlay now
restates all five explicitly for the same reason LONGHORN_DATA_PATH is restated —
a silent drift in base would ORPHAN the backups dev's PROVEN restore depends on.
The empty-prefix case was the one real risk, and it is settled empirically: with
prefix "" the chart omits objectStorage.prefix from the rendered
BackupStorageLocation ENTIRELY (helm template, chart 12.1.0), so dev's live BSL is
unchanged, not merely equivalent.

R2's TWO GOTCHAS, both wired up front:
  - region must be exactly `auto`. head-bucket answers {"BucketRegion":"WNAM"},
    which is a PHYSICAL LOCATION HINT, not a signing region. This was hardcoded
    us-east-1 inside the Velero HelmRelease — correct-by-accident for MinIO, wrong
    for anything else — so it is a knob now.
  - checksumAlgorithm: "". velero-plugin-for-aws v1.14.2 bundles an AWS SDK with
    flexible checksums on by default and sends x-amz-sdk-checksum-algorithm /
    x-amz-checksum-crc32 on every PUT; R2 rejects those with HTTP 400
    InvalidArgument, failing every backup and every kopia blob upload. It must be
    PRESENT-but-empty (the plugin branches on the key existing), and the chart does
    emit an empty value — verified by rendering it. Harmless against MinIO, so it
    is unconditional rather than a fourth knob.

WHAT THIS DOES NOT DO. Velero stays SUSPENDED on prod. `spec.suspend: true` is
owned by field manager `flux` (verified: kustomize-controller's managedFields do
not include f:suspend), so server-side apply will not strip it, and nothing here
declares suspension — which would also trip R-ENV-03, since a prod overlay may
patch only cluster-vars and a Flux Kustomization's `decryption`. Unsuspending is
the operator's, after `standup.sh --s3-endpoint <r2> s3check` proves a round trip.

NO DNS KNOB IS TOUCHED. BASE_DOMAIN stays prod.home.keithjackson.dev and every
EXTERNALDNS_* value is untouched. The apex inversion on work/prod-standup-campaign
was deliberately NOT carried: this branch ports that branch's R2 reasoning knob by
knob, and merges nothing.

VERIFIED: ci/l0.sh green (flux-postbuild-substitution 272 assertions, 0 hazards,
33 knobs defined / 28 referenced, every new token resolved in BOTH overlays);
render-golden, lint, schema, spec-immutability green; touched requirement
R-STATE-03 covered.

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 9739e9be91 chore(backup): R2 credentials for the off-cluster DR target
Written by platform/backup/set-r2-credentials.sh (operator, 2026-09-07T05:41:34Z)
into all four consumers, in the two shapes they need: velero wants an AWS INI
file, CNPG/barman wants discrete ACCESS_KEY_ID / ACCESS_SECRET_KEY. All four
verified to carry the SAME 32-character key id, so no consumer was missed.

Proven from a pod INSIDE prod against
https://7ce452a1b3d6c86daf2c020edcb82d37.r2.cloudflarestorage.com:
head-bucket on k3s-prod-backup returns BucketRegion WNAM, and PUT and DELETE both
succeed. Byte-integrity of GET is NOT yet proven (the aws-cli image has no cmp);
s3check is what will establish it.

Credentials only — no endpoint or bucket wiring. That is feat/r2-backup-prod.

jakman85andClaude Opus 5 d1a6628a97 feat(ha): the CNI dials the control-plane VIP — kube-vip becomes a CNI prerequisite
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
OPERATOR DECISION 2026-09-06: "use the VIP as intended — a virtual address to reach
the cluster and provide fault tolerant HA. Without a change it will not work in HA."

THE DEFECT. Cilium's kube-proxy replacement dialled a SINGLE NODE. Re-confirmed live
before changing anything: all three prod cilium-agent pods carried
KUBERNETES_SERVICE_HOST=192.168.2.10 — k3s-prod-1's own address — while the kube-vip
VIP 192.168.2.9 was Running on all three nodes with a held lease. Lose prod-1 and the
CNI's control-plane path is dead on an "HA" cluster. clusters/prod's own comment said
the value must be the VIP and NOT .10, then called it "Not yet decided" — I treated
that stale comment as an open question when the evidence already settled it.

SPLIT, NOT REPOINT, because k3s_api_host had two consumers with opposite needs:
  k3s_api_host            unchanged — the FOUNDER's IP: the cold-bootstrap join
                          target and a tls-san. infra/tofu/outputs.tf GENERATES this
                          name, so renaming would ripple into tofu and the runbooks.
  k3s_apiserver_endpoint  NEW = {{ kube_vip_address }} — the HA address; what Cilium
                          consumes. Derived, not restated, so an environment overrides
                          ONE line and the VIP, the SAN and the CNI endpoint move
                          together. Prod needed no new override.

THE SECOND HAZARD, WHICH MY BRIEF DID NOT NAME and the agent found: pointing Cilium at
the VIP breaks a COLD bootstrap for the same reason the join would — site.yml ran
node-baseline -> k3s -> cilium, so Cilium would install against an address nothing
announced yet. That is the 2026-09-01 deadlock shape. Fixed by SEQUENCE, not value:
site.yml now imports kube-vip.yml BETWEEN k3s and cilium. It cannot go earlier
(kube-vip is a k3s auto-deploy manifest, so it needs a cluster) and it works there
because the DaemonSet is hostNetwork with KUBERNETES_SERVICE_HOST=127.0.0.1 — needing
neither CNI nor kube-proxy. roles/kube_vip gained a read-only `wait_for` on the VIP so
a cold run stops THERE with a named cause instead of surfacing as unreachable agents.

Also fixed a pre-existing bug that only mattered once this play joined site.yml: the
role's read-only interface probe ran without `check_mode: false`, so under --check it
was skipped and the assert fired with a misleading "set kube_vip_interface explicitly".

VERIFIED BY ME, not just reported:
  renders    dev K3S_API_HOST=192.168.1.49   prod=192.168.2.9  (each environment's VIP)
  cilium     template consumes k3s_apiserver_endpoint, not k3s_api_host
  cold join  still `--server https://{{ k3s_api_host }}:6443` — the founder
  order      site.yml: node-baseline -> k3s -> kube-vip -> cilium -> verify -> flux
  gate       full CI gate PASS
Agent-side, additionally: in-memory render of cilium-values.yaml.j2 per host showing
k8sServiceHost=the VIP with the join still on the founder; k3s_tls_sans renders
['.10','.9','127.0.0.1','.11','.12'] so NO cert reissue and NO k3s restart is involved
— .9 already answers under full CA verification; and --check --diff of kube-vip.yml
against prod reported 6 ok / 0 changed, i.e. the role edits change nothing about the
kube-vip prod already runs.

ha-control-plane-as-code 92 -> 112 assertions, turning two escalations into machine
checks: the Cilium template must use the endpoint var; the endpoint must derive from
kube_vip_address and k3s_api_host must not; per environment K3S_API_HOST must equal
that environment's VIP and be none of its node IPs (the [parity] contract, now
machine-checked rather than a comment); site.yml must order k3s -> kube-vip -> cilium.
Every new assertion mutation-tested and bites. One honest negative recorded: reverting
only the BASE default is not caught, because both overlays patch the key — the check
reads effective per-environment values, so the base default is unguarded.

APPLY ORDER, and this is the operator's step — nothing was applied:
  PROD FIRST, and it is the low-risk direction (prod is the broken one). Push and let
  Flux reconcile platform/cilium: the value change rolls the cilium-agent DaemonSet
  ONE NODE AT A TIME (maxUnavailable: 1 — the knob that bounded the 2026-09-01
  incident), it will not proceed past an unready pod, existing datapath survives an
  agent restart, and .9 is already live before the change lands.
  DEV SEPARATELY, operator present. Same mechanics but live dev agents dial
  192.168.1.50, and dev is mid-DNS-migration on dev-live. Do not fold it into that.
  ANSIBLE: nothing to run for either live cluster; the Ansible half matters only for a
  cold build. Remove the now-redundant standalone kube-vip.yml step from any runbook.

NEW NAMED GAP, unwritten: the L2 test cannot assert the running agents' live
KUBERNETES_SERVICE_HOST, which is the drift the L0 check cannot see. Recorded in that
test's gap list.

jakman85andClaude Opus 5 f178d85c71 fix(kyverno): unblock CDI imports by SATISFYING the label requirement, not exempting it
Prod's UniFi VM has no disk. `DataVolume unifi/unifi-rootdisk` stuck in
ImportScheduled for hours, because Kyverno denied CDI's own generated pod:

  validate.kyverno.svc-fail denied Pod/unifi/importer-prime-<uid>
    require-auth-mode-label     (R-IDP-02)
    require-egress-class-label  (R-NET-05)

Both policies match any Pod in an `app-namespace: "true"` namespace with no
exclusion, and CDI generates `importer-*` itself — it cannot carry repo labels.
A COLD-START defect, not a prod quirk: dev's identical import Succeeded 9 days
ago, before the policies enforced, so dev has never exercised it and would hit it
on any rebuild. Fourth bug of this shape in two days.

MECHANISM: a MUTATE ClusterPolicy that ADDS
`egress-class: internet` + `auth-mode: none` (add-if-absent anchor) to Pods on
CREATE in app namespaces WHEN the requesting subject is ServiceAccount
`cdi/cdi-sa`. Both validate policies are untouched — no exclude, no exception,
`background: true` preserved on them.

Why mutate beats exempting: the requirement stays literally true ("every pod in an
app namespace declares both labels") and the values are HONEST — the importer does
pull over the default WAN path, and `internet` is the least-reach class (it does
not grant the VPN path); a transient worker pod with no UI genuinely is
`auth-mode: none`.

THE MATCH IS IDENTITY, NOT A NAME. `subjects: ServiceAccount cdi/cdi-sa` is the
AdmissionReview userInfo, taken from the real prod denial
(`system:serviceaccount:cdi:cdi-sa`, name importer-prime-…, op CREATE). A name
prefix is attacker-choosable; a requesting ServiceAccount is not — and the test
proves it, with a fixture `importer-prime-forged-by-an-app` that copies both the
name prefix AND CDI's labels and is still DENIED. Covers every CDI worker kind
(importer/uploader/cloner) without enumerating names that change per release.
Confirmed on prod that cdi-sa is the only cdi-namespace SA that can create pods.

REJECTED, and the first one is a trap worth recording:
  * PolicyException — the CRD EXISTS (v2/v2beta1, from the pre-applied bundle) but
    all controllers run `--enablePolicyException=false` (verified live on prod:
    admission, background and reports controllers all carry the flag). An exception
    would apply cleanly through Flux and be SILENTLY IGNORED. Enabling the gate is a
    cluster-wide capability change for no gain over the mutate.
  * `exclude` scoped to cdi-sa — sound identity, worse consequences: any userInfo
    match forces `background: false`, which would drop background scanning and
    policy-report coverage of R-NET-05/R-IDP-02 for ALL EXISTING PODS to fix one pod
    class. It also leaves the importer with no labels at all — the unlabelled
    fall-through that require-egress-class-label's own header calls a fail-open leak.
  * name-prefix / CDI-label matching — attacker-choosable, and proven walkable.

TWO-WAY PROOF, non-vacuous by construction — same resource, different requester,
opposite outcomes (verified by me, not just reported):
  userinfo cdi-sa   -> mutate pass, require-egress-class pass, require-auth-mode pass
  userinfo ordinary -> mutate SKIP,  require-egress-class FAIL, require-auth-mode FAIL
Kyverno L0 went 17 -> 29 tests passed, 0 failed. The mutate policy is deliberately
kept OUT of the existing tests/kyverno-test.yaml: that suite declares no userinfo,
and without userinfo the offline engine does not discriminate on subjects — it
mutates everything, which would have silently turned its negative rows into passes.

platform-config/kustomization.yaml is the live apply path for these ClusterPolicies;
without it the policy never reaches a cluster.

RESIDUAL TRADE-OFF, reversible by deleting one file: anything created by cdi-sa in
an app namespace now has these labels supplied rather than being rejected for not
declaring them — including a pod that is not a CDI worker. That identity already
holds `pods create/delete` cluster-wide via ClusterRole `cdi`, so it is not a new
capability; what changes is that for that one identity the declaration is assumed
rather than demanded. restrict-host-namespaces, the namespace default-deny baseline
and the CiliumNetworkPolicies all still apply.

FIRST resource-mutating policy on this cluster: kyverno-resource-mutating-webhook-cfg
holds 0 webhooks today; with autoUpdateWebhooks=true Kyverno registers
mutate.kyverno.svc-fail for Pods within seconds of this applying. Prod's
forceFailurePolicyIgnore=false makes it failurePolicy: Fail — same posture as the
validating webhook already in that path.

CDI retries importer creation on a loop, so the stuck import should proceed once
this lands. The detached prime-be3f9d1c-… 40 GiB scratch PVC is separate operator
cleanup; untouched, as is the DataVolume.

VERIFIED: full CI gate PASS. Nothing applied to any cluster.
