jakman85andClaude Opus 5 e72050c690 docs: correct CI/platform documentation that was stale, wrong, or load-bearing
gate / gate (push) Successful in 1m37s
gate / gate (pull_request) Successful in 1m36s
gate / conformance (push) Has been skipped
gate / conformance (pull_request) Has been skipped
The 2026-09-29 session found the merge gate did not exist -- no branch protection, no
runner -- while the tree asserted both. This corrects the documents that carried, and in
several cases CAUSED, that belief.

CLAUDE.md gains section 2b: never infer platform state from this repository. It carries
the specific API and kubectl checks for protection, runners, CI status, workloads and
Flux revisions, and the rule that a green tick is not proof anything ran (a skipped Gitea
job reports success). This is the rule whose absence produced every other finding.

.gitea/workflows/README.md and merge-gate.yaml both said "there is no remote git host,
this file is dormant". Gitea had been live for weeks. Both were written as plans and never
revisited once the plan completed. The Transition section is now marked COMPLETE and says
what is genuinely still outstanding (CLUSTER_AVAILABLE unset, so L2/L3 never runs in CI).

DECISIONS-LOG 2026-08-31 is annotated IN PLACE. Anyone reading chronologically previously
hit "required status check; runner incluster-dind online" with nothing marking it false
until a month later. The correction now sits on the bullet itself.

ci/README.md, clusters/README.md and both conformance READMEs carry a status banner: they
speak as though no cluster exists, which makes a live L2/L3 coverage gap read as an
expected phase. That framing is why the gap went unexamined.

apps/wave-1/gitea-actions-runner-secret.sops.yaml: fixed a wrong path, replaced advice to
`sops -d` into a terminal (which CLAUDE.md forbids) with the rotation script, and recorded
that a fresh token alone does not re-register a runner holding a stale /data/.runner.

apps/wave-0/plex-claim-secret.sops.yaml: the header claimed the file ships the placeholder.
It has not since the claim -- it holds the spent token, which is inert and deliberately
left in place.

catalog/plex.yaml and the plex secret both asserted a "~4-minute TTL" as fact. It was
uncited, upstream documents no expiry, and it was the basis for a since-disproven claim
that the pipeline was too slow to fit inside it. Measured: ~2m45s.

Both .sops.yaml files were verified to still decrypt after the comment edits
(`sops -d > /dev/null`), and render==golden confirms the catalog comment does not
propagate into the rendered manifest.

jakman85andClaude Opus 5 234cc6a71a docs(gitea): a skipped job reports SUCCESS, not pending -- correct the deadlock claim
gate / gate (push) Successful in 1m33s
gate / gate (pull_request) Successful in 1m32s
gate / conformance (push) Has been skipped
gate / conformance (pull_request) Has been skipped
The runner came up on 2026-09-29 and the first CI jobs this repo has ever run went
green, which falsified a claim merged in #2.

MEASURED:
  gate / gate (pull_request)          success   1m58s (PR 1), 1m34s (PR 2)
  gate / gate (push)                  success   1m32s (PR 2 only)
  gate / conformance (pull_request)   success   "Has been skipped"

#2 said listing the conformance context as a required check would deadlock every PR,
because the job is `if: false` and never runs. That is wrong. Gitea reports a skipped
job as SUCCESS. Requiring it would not deadlock anything -- it would pass VACUOUSLY,
forever, while nothing ran.

The conclusion is unchanged (never require it) but the reason inverts, and the corrected
reason matters more: under HARD RULE 4 a permanently-green check that verifies nothing is
worse than a deadlock. A deadlock is loud. This is the exact fail-open shape the
2026-09-18 audit and this one both keep finding.

Also records that the (push) contexts only appear for branches matching gate.yml's push
trigger -- feature/**, fix/**, docs/**, chore/** -- and NOT feat/**, which is why PR 1's
feat/ branch produced only pull_request contexts. Require the pull_request context alone,
or PRs from non-matching prefixes never satisfy the rule.

CLAUDE.md's enforcement table is updated: the runner half is genuinely fixed and observed
green, the branch-protection half is not. Adds the warning that a green tick is not by
itself evidence that anything ran.

jakman85andClaude Opus 5 fe862ab527 infra(gitea): recover the Actions runner before anything requires the gate
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
gate / gate (pull_request) Successful in 1m32s
gate / conformance (pull_request) Has been skipped
No runner is registered at repo, org or site level, so gate.yml has never executed.
PR #1 sat pending for 30.6 minutes across 122 polls and never reported. Requiring the
gate as a status check in that state would lock the repo permanently.

Adds runner-token-rotate.sh: mints a fresh instance-level registration token from the
Gitea API and writes it into the SOPS secret via sops set, without ever printing the
value.

Records the likely root cause, which a new token alone does NOT fix. act_runner
registers once and persists its identity in /data/.runner on the act-runner-data PVC.
If Gitea no longer holds a matching runner row, the pod starts, sees .runner, SKIPS
registration entirely, and polls with an identity Gitea does not recognise. Symptom:
zero runners, pod running, nothing obviously broken. Clearing the PVC is what forces a
genuine re-registration.

The README now sequences runner-first, enforcement-second, and requires CONFIRMING the
runner reports online rather than assuming it. That assumption is the whole defect:
DECISIONS-LOG recorded the runner as online on 2026-08-31 and nobody checked since.

jakman85andClaude Opus 5 a2665c0511 infra(gitea): script the branch protection that was never applied
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
gate / gate (pull_request) Successful in 1m33s
gate / conformance (pull_request) Has been skipped
Gitea repo settings live in its own database, not in a manifest Flux reconciles, so
they are drift-prone and invisible to the conformance gate -- which is how main came
to accept direct pushes while the log recorded it as protected.

Adds infra/gitea/branch-protection.sh (blocks direct pushes to main) and a README
carrying the measured before-state and the ORDER the remaining steps must happen in.

The script deliberately leaves enable_status_check:false and required_approvals:0.
Both would deadlock today: there is no runner to satisfy a required context, and the
only human account is not yet a repo collaborator, so no one could supply an approval.
The README sequences both.

It prints a push probe to run afterwards. The API response is not proof -- Gitea may
let site admins bypass protection, and that has to be observed, not assumed.

gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
gate / gate (pull_request) Successful in 1m33s
gate / conformance (pull_request) Has been skipped
Going to land the plex claim wiring through the documented PR flow surfaced that
the flow has never run. PR #1 is the first pull request this repo has ever had.

Verified against the live Gitea, not inferred from the docs:
  * branch_protections is [] -- main is protected:false, enable_status_check:false,
    status_check_contexts:[], required_approvals:0, user_can_push:true
  * ZERO Actions runners registered at repo, org and site level

DECISIONS-LOG 2026-08-31 asserts a "required status check" and a runner
"incluster-dind online". Both are false of the live system. The gate is neither
enforced nor able to run, and that went unnoticed because the log claimed
otherwise -- the same fail-open class as the two holes found on 2026-09-18.

Adds CLAUDE.md, the first agent-facing delivery doc here: the
branch -> PR -> gate -> approval -> merge rule, stated alongside the honest fact
that enforcement is currently weaker than the rule, so agents follow the rule
rather than what they can get away with. Carries the toolbox gate invocation, the
two git-worktree workarounds, the rc 0/1/3 contract, and secret handling.

Records the ordering trap: enabling a required status check before a runner exists
deadlocks every PR permanently, including the one that would fix it.

jakman85andClaude Opus 5 4fd75ccdaa feat(plex): wire PLEX_CLAIM from a SOPS Secret so the server can be claimed
gate / gate (pull_request) Successful in 1m58s
gate / conformance (pull_request) Has been skipped
Plex cannot create libraries over the already-mounted 8.33T NFS bulk share while
the server is UNCLAIMED. catalog/plex.yaml carried a long argument for leaving
PLEX_CLAIM unwired; the operator has decided to override it. This implements the
wiring in the way that respects the half of that argument which is still true.

WHAT WAS TRUE AND STILL IS: a https://plex.tv/claim token has a ~4-minute TTL,
far shorter than commit -> push -> Flux reconcile -> pod-roll on its own timers.
So the committed value is a documented PLACEHOLDER and the live token is injected
by the operator inside that window, with the reconcile FORCED rather than waited
for. runbooks/plex-claim.md is that timed procedure.

WHAT WAS NOT TRUE: the old comment claimed "a placeholder/absent claim Secret
would crashloop the pod". Half of that is wrong, and the difference is the whole
design. Established from plexinc/pms-docker's own first-run script (branch
`master`, root/etc/cont-init.d/40-plex-first-run, s6-overlay v2), cross-checked
byte-identical against the same file inside the running :latest image:

  * the claim exchange (line 106) is gated on PLEX_CLAIM being non-empty AND the
    PlexOnlineToken pref in /config being empty. Once the server is claimed the
    block is skipped entirely, so the env is a NO-OP on every later start
    whatever it holds ("If server is already logged in, this parameter is
    ignored" -- upstream README).
  * with an invalid/expired token on a still-unclaimed /config, plex.tv answers
    403 with an empty body; curl's status is never checked, the token sed yields
    empty, the success branch at line 120 does not fire, there is no else branch
    and no non-zero exit, and the script (no `set -e`) exits 0. The pod comes up
    UNCLAIMED AND SERVING. It does not crashloop.
  * the image never sets S6_BEHAVIOUR_IF_STAGE2_FAILS (default 0 = continue even
    if a cont-init script failed), so even a non-zero exit would not halt
    startup.

An ABSENT Secret is the real hard failure (secretKeyRef has no `optional`, so it
is CreateContainerConfigError), which is why the Secret is committed, encrypted
and listed in the wave kustomization rather than hand-created at claim time.

NO SCHEMA CHANGE. `optional` on secretKeyRef would only be needed if the pod had
to tolerate a missing Secret or could not start without a VALID token. Neither
holds: the Secret always exists in the Flux graph, and an invalid token is
non-fatal. schemas/servicedefinition.schema.json is untouched, and so are
catalog/render.py's env emission and the renderer contract.

Changes:
  * apps/wave-0/plex-claim-secret.sops.yaml -- new Opaque Secret plex-claim/plex,
    key PLEX_CLAIM, SOPS-encrypted to the committed age recipient. Its header
    carries NO dollar-brace expressions on purpose: kustomize preserves body
    comments into the stream envsubst reads (per
    conformance/tests/l0-static/flux-postbuild-substitution), so quoting the
    upstream shell conditions verbatim would have been a live substitution
    hazard on apps-wave-0, not prose.
  * catalog/plex.yaml -- the PLEX_CLAIM env via valueFrom.secretKeyRef, the
    "deliberately NOT set" block rewritten around the TTL + one-shot design, and
    the stale crashloop claim in the /config storage comment corrected.
  * apps/wave-0/plex.yaml -- re-rendered with the canonical command
    (`--all catalog -o apps --wave-layout --no-image-automation`). No L1 golden
    under conformance/tests/l1-rendering covers plex, so this is the only
    rendered surface that moves.
  * catalog/render.py -- plan_apps_waves places `<svc>-claim-secret.sops.yaml`
    in the app's OWN wave, like the bootstrap secret, plus a selftest assertion.
    Without this, the next `--emit-waves` would have silently dropped the Secret
    from apps/wave-0/kustomization.yaml and put the pod into
    CreateContainerConfigError. apps/wave-0/kustomization.yaml is the hand-pruned
    subset (vm-demo/keycloak are rendered but deliberately unlisted), so its one
    new line was applied without re-emitting the rest.
  * runbooks/plex-claim.md + its kustomization.yaml generator entry + README
    index -- the operator procedure that fits in 4 minutes, including the single
    forced-reconcile command and the mandatory pod roll (a changed Secret does
    NOT restart anything: PLEX_CLAIM is read only at container start and the pod
    template is byte-identical across this change).

Touched requirements: R-SEC-01 (secrets encrypted at rest), R-GITOPS-02
(ServiceDefinition onboarding contract).

gate / gate (push) Has been cancelled

2026-09-19 01:00:59 -05:00
jakman85andClaude Opus 5 712f4c9336 fix(conformance): "unit-tested" counted an alert MENTIONED in a comment as tested
alert-rules-unit-tested decided whether an alert had a unit test with a bare word
match over the whole test file. Any mention counted — including prose in a `#`
comment.

Hit for real while adding platform/monitoring/tests/vpn-egress.test.yaml. Its header
explains that VPNTunnelDown stays quiet during an egress-steering failure, and that
sentence alone made this check declare VPNTunnelDown "asserted on" and demand its
removal from UNTESTED_ALERTS. Removing the entry would have recorded coverage that did
not exist — the precise "looks fixed" outcome this check exists to prevent, produced
by the check itself. (In that instance I made the coverage real instead, which also
exposed that the fixtures were missing tun0's receive counter entirely.)

Now an alert counts only when a test file names it in an assertion position, with
comment lines stripped first so a commented-out assertion does not count either.

BOTH promtool idioms are accepted, because both are real assertions:

    alert_rule_test:    - alertname: CNPGPrimariesCoLocated
    promql_expr_test:   - expr: 'ALERTS{alertname="CNPGPrimariesCoLocated"}'

Matching only the first is not a stricter check, it is a WRONG one: it reported
CNPGPrimariesCoLocated as untested when platform/cnpg/alerts.promtool-test.yaml pins
it across four scenarios entirely through the second form. Believing that would have
produced a redundant duplicate test for an alert already covered better than most —
so the first version of this very fix had to be corrected before it landed.

MEASURED BEFORE LANDING, because the registers are shrink-only and a prose-only alert
would have required an entry this check forbids adding: of 61 alerts, 32 are asserted
in one of the two idioms, 29 are not mentioned at all (already declared), and ZERO were
prose-only. So this tightening failed nothing on the day it landed.

My first measurement said 31/30/0 and was wrong in a way worth recording: it scanned
only tests/*.test.yaml and missed the <manifest>.promtool-test.yaml companion
convention, which is exactly what hid the CNPGPrimariesCoLocated false negative.

Verified in both directions: 134 assertions pass with the real coverage intact, and a
temporary prose-only mention of NodeExporterDown (a registered untested alert) leaves
it correctly listed as untested instead of triggering the stale-entry failure.

Gated: offline l0,l1 --include-scope whole-repo — 24 cases, 0 failures, 0 skips,
0 unwired.

jakman85andClaude Opus 5 a3f4ddb971 merge: feat/egress-gateway-staleness-alert — finished so it can actually pass the gate
Brings the two alerts for the silent egress-gateway failure: VPNEgressSteeringStale
(critical) and VPNEgressUplinkLabelMissing (warning), plus the kube-state-metrics
allowlist entry that makes them non-inert.

WHY THE BRANCH SAT IN THE BACKLOG: it could not pass the merge gate. Three
whole-repo checks failed on it, and each one was a real gap rather than a nuisance:

  * alert-runbooks-resolvable — both alerts link to /runbooks/vpn-egress-stale,
    which did not exist. An alert firing now would hand the operator a 404.
  * alert-rules-unit-tested — alerts.yaml is already a covered file, so new rules
    in it must be tested or a "tested" file quietly grows untested rules.
  * alert-metrics-have-scrape-targets — see the guard bug below.

WHAT THE ALERTS CATCH. egress-class=vpn pods leave through one gateway node's tun0;
Cilium resolves it to an ifindex and caches it. An OpenVPN reconnect destroys and
re-creates tun0 with a NEW ifindex, and the node label
homelab.keithjackson.dev/egress-uplink=<addr>-<ifindex> is what forces Cilium to
re-resolve. If the label does not follow the tunnel, the cache points at a destroyed
interface and every vpn-class pod is silently dropped — while tun0 stays up and
VPNTunnelDown says nothing. That ran ~80 minutes undetected on the dev gateway.

Verified this is live on prod, not inert: k3s-prod-3 carries egress-gateway=true and
egress-uplink=10.150.192.86-139, and vpn-egress-steering has been in place 14 days.
The label was exported on 0 series before this change, so the allowlist entry is
what switches the alerts on.

runbooks/vpn-egress-stale.md — written and wired into the configMapGenerator, with
the four required operator sections. It leads with proving egress from a pod the
policy selects, because the symptom is "outbound traffic silently disappears", and
it says plainly not to "fix" this by deleting the policy: that does not restore
egress, it sends vpn-class traffic out of the real ISP connection, which is the leak
the class exists to prevent.

platform/monitoring/tests/vpn-egress.test.yaml — four promtool fixtures. 1 and 2 are
the SAME tunnel reconnect with and without the label following it, which isolates the
mechanism the rule actually keys on: a label VALUE change is not a changing sample,
it retires one series and starts another. 3 is the inert case (gateway node, no uplink
label) where the critical rule CANNOT fire, which is why the warning exists.

Two fixes the branch needed that were defects in the checks themselves:

1. alert-metrics-have-scrape-targets asserted the KSM allowlist matched
   `nodes=[...egress-gateway]` with a literal closing bracket — i.e. that the list
   contained EXACTLY that one label. Adding a second label correctly (egress-uplink,
   which these alerts need) therefore FAILED the check while the property it guards
   was perfectly satisfied. Loosened to `[,\]]`: in the list, not the whole list. A
   guard that breaks when you correctly extend the thing it guards teaches people to
   edit the guard, which is how it stops guarding.

2. UNTESTED_ALERTS listed VPNTunnelDown, and the check flagged it as stale because
   "asserted on" is a bare word match over the test file — my header COMMENT
   mentioning VPNTunnelDown was enough to count as coverage. Rather than delete the
   register entry and claim coverage that did not exist, the fixtures now assert
   VPNTunnelDown QUIET in all four cases. That required making them faithful: they
   had no node_network_receive_bytes_total{device="tun0"} at all, so VPNTunnelDown
   would have been firing throughout unnoticed, because promtool only checks the
   alertnames you name. A healthy tun0 passes traffic, and that silence IS the claim
   these rules exist for.

NOTE FOR LATER, not fixed here: that word-match means any alert named in prose counts
as tested. Tightening it to `alertname:` positions could reveal other prose-only
"coverage", and the register is shrink-only, so the cascade wants doing deliberately
rather than at 01:00 unattended.

Conflicts resolved: kept HEAD's Velero custom-resource-state block and took only the
branch's one-line allowlist change (14 lines down to 1); inserted the branch's
2026-09-12 DECISIONS-LOG entry in date order rather than appending it out of sequence.

Gated: offline l0,l1 --include-scope whole-repo — 24 cases, 0 failures, 0 skips,
0 unwired. The new unit tests pass under the pinned promtool 3.14.0.

jakman85 5f3ea63b7f merge: fix/touched-requirements-maps-apps-and-c2 2026-09-19 00:39:21 -05:00
jakman85andClaude Opus 5 23c335257b fix(ci): apps/* and the C2 UI attributed no requirement, so no behaviour test gated them
ci/touched-requirements.sh's coarse path map had no arm for apps/*. A change adding
or editing ANY workload on the cluster — 49 tracked manifests across apps/wave-0,
-1, -2 and apps/vms — attributed zero requirements, so the merge gate selected only
the whole-repo-scoped checks and none of the requirement-scoped L2 behaviour tests.
The tests that enforce default-deny, egress class and auth mode did not run on
exactly the changes that can violate them. Kyverno admission and the L0 egress-path
check are real backstops, but admission is post-merge and the gate exists to catch
it first.

platform/homepage and platform/headlamp were unmapped too — the C2 UI. That gap was
already written down in changed_diff()'s rule-3 comment ("the ONLY route to
R-C2-01/02 was rule 3", i.e. editing the C2 test itself) and had sat there since.

Twelve arms added: apps/vms/* (ordered BEFORE apps/*, because `case` takes the first
match), apps/*, platform/homepage|headlamp, platform/kubevirt, platform/gateway,
platform/coredns, platform/crafty, platform/external-snapshotter|backup, runbooks/*,
platform-config/*, platform/kustomization.yaml and .sops.yaml.

platform/kustomization.yaml earns its own arm: it is the assembly list, so one
deleted line disables an entire platform component while every file it points at
stays perfectly valid on disk. That is the most consequential single-line edit in
the repo and it attributed nothing.

Measured effect for an apps/ change, via --print-selection:

    before:  0 requirement-scoped tests
    after:   13  (3 L1, 8 L2, 2 L3)

Coverage stays 51/51, so the gate's "attributed IDs must be covered" assertion does
not false-block.

Ten new assertions in ci/tests/touched-requirements.test.sh (26 total, all passing),
including the ORDER property — apps/vms/* must win over apps/* — because arm order
is a real failure mode of `case`, not merely a question of both arms existing. Each
fixture cites no R-ID of its own, so any ID in the output came from the PATH and not
the content scan.

A correction on numbers I reported earlier in this session: I claimed "192 unmapped
files", then "182". Both were inflated by my own audit script rather than the repo.
Its regex used `[^)]*`, which matches across a newline, so the first arm parsed as
`case "$1" in\n    catalog/*` and never matched anything; I also mis-parsed
alternation arms like `.gitea/*|ci/*`, which made ci/ look unmapped when it is
mapped. True remainder after this change is 18 files, all prose or captured
artifacts (docs/plans/, root READMEs, .standup-dns/*.txt).

Gated: offline l0,l1,meta --include-scope whole-repo, exit 0.

condition was unproven here and an unparseable policies.yaml breaks EVERY backup.
It said "revisit if the shape shows up elsewhere."

It showed up elsewhere within the hour. A verification Backup came back
PartiallyFailed with 4 errors, all in ns runbooks: the nginx Deployment's emptyDir
`tmp` + `cache`, failing with

    error to expose PVB: error getting client pod runbooks-...: pods "..." not found

because pushing a runbook edit rolled that Deployment while the backup was
snapshotting it. Cause worth stating plainly: I triggered that rollout myself, so
those four failures were self-inflicted rather than a standing defect — but the
mechanism is not. A PVB exposes the volume through its pod, so ANY rollout landing
in the backup window fails one, and one failed PVB makes the whole Backup
PartiallyFailed. On a GitOps cluster that is routine.

So the property is what matters, not the namespace: an emptyDir is created empty
with its pod and destroyed with it, so backing one up cannot protect anything
while attempting it can break the backup that protects everything else.

The `volumeTypes` risk was retired by testing, not by hoping. The new policy went
into a THROWAWAY ConfigMap first, leaving the live one untouched, and was proven
on prod (velero 1.18.1) with a control:

    control, ns runbooks, NO policy  -> 4 PodVolumeBackups (2x tmp, 2x cache), Completed
    same namespace, WITH the policy  -> 0 PodVolumeBackups, Backup Completed, 0 errors

The control is the point — "zero PVBs" alone is equally consistent with nothing
having been attempted, which is the kind of empty green I have shipped before.

The ns velero exclusion is now reverted as redundant: `plugins` and `scratch` are
emptyDir (verified on a live maintain pod), so the general rule covers them, and
reverting keeps Velero's own resources in schedule (1) where they belong instead
of moving them between schedules for no reason.

Gated: L0 whole-repo 21 cases, 0 failures, 0 skips, 0 unwired.

jakman85andClaude Opus 5 cde02d19d2 fix(runbooks): node-memory-swap claimed the CNPG primaries sit on node 1
They do not, and the correction changes the operator's plan rather than just a
detail.

Verified live: all three CNPG clusters run 3 instances spread one per node by
required anti-affinity, and k3s-prod-1 holds a REPLICA of each (keycloak-db-2,
nextcloud-db-2, semaphore-db-2). No primary is on node 1, so draining it forces
no failover at all — the best state this maintenance could ask for. The original
sentence was carried over from earlier session state and was simply stale; the
runbook now prints the command to re-derive it, because primaries move on their
own after any restart or failover.

Adds the warning that matters more. CNPGPrimariesCoLocated is currently firing
for k3s-prod-2, which holds both the keycloak-db and semaphore-db primaries. The
instinct is to tidy that before a maintenance window. Doing so would be actively
harmful here: rebalancing means promoting a replica, the only node with spare
primary capacity is node 1, and so "fixing" the alert would put a primary on the
very node about to be powered off — converting a no-failover drain into a
two-database failover. Rebalance after node 1 is back and caught up.

jakman85andClaude Opus 5 d99d47494c fix(velero): nightly backup PartiallyFailed on Velero's own maintenance Jobs
VeleroNoRecentBackup has been firing CRITICAL on prod over a backup that was
actually protecting everything.

velero-daily-20260919030041: PartiallyFailed, 3079/3079 items backed up, exactly
2 errors — both PodVolumeBackups for the `plugins` and `scratch` volumes of
homepage-default-kopia-maintain-job-1789786837269-qhsvh. Four such PVB failures
had accumulated.

Velero runs transient kopia repository-maintenance Jobs in its own namespace, one
per BackupRepository, each with emptyDir `plugins` and `scratch` volumes. Schedule
(1) runs defaultVolumesToFsBackup:true — the opt-out model — so it attempts
fs-backup on those volumes too. The Job finishes and its pod disappears
mid-backup, and the PodVolumeBackup fails.

Nothing real was ever missed. But PartiallyFailed does not advance
velero_backup_last_successful_timestamp, so the alert that exists to catch a
genuine backup outage fires every night over Velero cleaning up after itself. An
alert that cries wolf nightly is how a real failure gets ignored — and this one
guards R-STATE-03.

Fix uses the pattern already established for monitoring+unifi: exclude the
namespace's volume DATA from schedule (1), keep its RESOURCES in schedule (2).
Safe by inspection — ns velero holds no PVCs, so there is no volume data to lose,
while the BSL, credentials and Backup CRs that DR actually needs are still
captured.

Deliberately narrower than the general rule. The general fix is a volume policy
skipping emptyDir by type, which would also cover a transient Job in any other
namespace, but it needs Velero's `volumeTypes` policy condition — unproven in this
repo on 1.18.1, and a policies.yaml Velero cannot parse breaks EVERY backup. That
is a much worse failure than the one being fixed, and all four observed failures
were kopia-maintain pods in ns velero. Rationale recorded inline so the next
person can widen it on purpose rather than by accident.

Gated: L0 whole-repo 21 cases, 0 failures, 0 skips, 0 unwired.

jakman85andClaude Opus 5 623fa14256 docs(decisions-log): PM handoff — two fail-open holes in the gate itself
Records the session's three pieces of work and, more importantly, the theme
joining them: the gate was reporting green over things it had not checked.

- runbooks/node-memory-swap.md, with the three claims I wrote and then removed
  because they were false (EtcdIsVoter does not exist here; node-drain-policy is
  not pinned so the runbook reads it live; the 5-vs-1 rebuild-limit confusion).
- The nested-worktree scan: six discovery sites auditing 18 copies of the repo.
- L1 rendering never running on a requirement-scoped gate, with the external-dns
  incident reproduced via --print-selection (0 tests before, 3 after).
- The two defects that surfaced in the meta-check guarding all of it.

PM HANDOFF lists the open items in priority order. The first is a judgement call
worth flagging rather than burying: the planned memory swap on k3s-prod-1 IS a
supervised single-node loss on prod, which is exactly the event R-STATE-02
describes and which is still proven only on the decommissioned dev cluster.
Capturing evidence during the swap costs nothing; manufacturing the event later
costs a second maintenance window.

jakman85 16cbd4a79e merge: fix/l1-rendering-declares-whole-repo-scope 2026-09-18 22:43:17 -05:00
jakman85andClaude Opus 5 755c08ab40 fix(conformance): the meta-check was layer-agnostic and reported failures silently
Declaring whole-repo scope on the L1 tests made whole-repo-invariants-wired
(R-TEST-03) fail. It was right to change behaviour and wrong about why, and it
could not tell anyone either way. Two independent defects.

1. LAYER-AGNOSTIC WHERE THE DESIGN IS LAYER-BOUNDED

The "every scope-declared test is selected despite a requirement filter matching
none" assertion compared EVERY scope-declaring dir against an `--layer l0`
selection. That silently assumed only L0 tests would ever declare the scope —
while ci/l1.sh was written from the opposite premise, that a whole-repo invariant
could appear at any layer. So the first L1 declaration made the check blame the
union for correctly excluding another layer.

Now partitioned by layer, and the L1 half of the property is asserted too:
every scope-declared L1 test must be selected by `--layer l1 --include-scope`,
and that selection must not leak non-L1 tests. That is what makes the L1
declaration load-bearing rather than decorative — previously nothing proved the
union reached L1 at all, because nothing at L1 declared the scope.

2. EVERY ASSERTION FAILED SILENTLY

The idiom throughout was a bare test on one line and `chk $?` on the next, under
`set -euo pipefail`. A false test aborts the script BEFORE chk can print, so the
diagnostic — which is the entire value of this check — was never reached. The
real failure above emitted 26 `ok` lines, rc=1, and no message at all; it read
as a tooling glitch rather than a finding.

All 12 assertion sites now capture the status (`chk $arc`) so the check reports
and continues. Proven by forcing MIN_DECLARED=999 against the real check: the
failure prints its full explanation and the run proceeds to the remaining
assertions, where before it died mute.

A meta-check that cannot say why it failed is worse than no meta-check.

Verified: 35 assertions, rc=0; full offline l0,l1,meta 25 tests / 0 failures.

jakman85andClaude Opus 5 b389566641 fix(conformance): L1 rendering never ran on a requirement-scoped gate
All three L1 tests now declare `conformance.home.k3s/scope: "whole-repo"`.

ci/l1.sh has passed --include-scope whole-repo since it was written, with a
comment saying no L1 test declared the scope yet and it was wired ahead of time
so the next whole-repo invariant "at any layer" would be picked up by annotation
alone. Nothing ever declared it. The consequence is that the entire L1 rendering
layer only ran when a touched path happened to attribute R-PLAT-02, R-NET-01 or
R-NET-05/06/07 — a fail-open hole for every other change in the repo.

The coupling requirement-scoped selection cannot see is that all three tests
exercise ONE code path: catalog/render.py against
schemas/servicedefinition.schema.json. Anything that changes rendered output
invalidates these goldens no matter which requirement the touched path maps to.

The 2026-09-04 external-dns merge is the proof, measured rather than asserted.
ci/touched-requirements.sh attributes platform/externaldns/helmrelease.yaml to
R-ENV-02, R-OBS-01/02/04, R-STATE-03 and R-TEST-01/02/03/04 — none of the
rendering requirements — yet that change added

    external-dns.alpha.kubernetes.io/controller: none

to the rendered output of all three goldens. Via --print-selection:

  requirement-scoped only (the 2026-09-04 behaviour):  0 L1 tests selected
  with --include-scope whole-repo (how ci/l1.sh runs): 3 L1 tests selected

So the merge gated GREEN while leaving every rendering golden stale, and the
staleness surfaced only on a later full run.

Also corrects the now-false comment in ci/l1.sh that said no L1 test declares the
scope, and records why the annotation is load-bearing there.

Verified: offline l0,l1,meta --include-scope whole-repo in the pinned toolbox —
25 tests, 0 failures, 0 errors, exit 0.

jakman85andClaude Opus 5 bc106caac1 docs(runbooks): node-memory-swap — replacing k3s-prod-1's mismatched DIMM pair
The operator has a matched 32 GB pair to install. k3s-prod-1 is the node that
needs it: DIMM1 is a Micron 8ATF2G64HZ-3G2E1 (16 GB, DDR4-3200, 1Rx8) and DIMM3
a 16ATF2G64HZ-2G6E1 (16 GB, DDR4-2667, 2Rx8), so capacity is correct at 32 GB
but the pair runs at the slower 2667. Nothing is faulty. k3s-prod-3 is a matched
Crucial pair.

The procedure exists because this node is the awkward one to take down: it held
24 Longhorn replicas, it is one of three etcd members (so the drain leaves
quorum at 2 of 3 with no further margin), and its rebuilds are the load that
starved etcd once already. So the runbook front-loads the checks that decide
whether to start at all, and treats a BLOCKED drain as the safety property
working rather than an obstacle to force past.

Two things it deliberately does not assert:

- node-drain-policy is not pinned in platform/longhorn/helmrelease.yaml, so the
  runbook has the operator READ the live Setting and set it before draining if
  it is not block-if-contains-last-replica, instead of assuming the default.
- Configured Memory Speed, not Speed, is named as the field that proves the
  swap worked — a matched pair being clocked down still reports the rated Speed.

It also flags the capacity decision as a decision: 2x16 GB keeps the three nodes
symmetric as PROD-PROVISIONING.md §2 assumes, while 2x32 GB makes node 1 the
asymmetric one on memory as well as disk.

Recorded caveats: the node-health artifacts de-duplicate DIMM part numbers, so
they can prove "two different modules" but cannot distinguish one module from
two identical ones — verification therefore collects dmidecode live. And node 2's
inventory is stale and self-contradictory (documented as the only single-DIMM
node at 16 GB, yet reporting ~31.1 GiB), so it needs re-inventory before anyone
claims three-way symmetry. This is NOT the §0b "do not buy RAM" case, which was
an EFI memattr kernel bug on node 2.

Wired into the configMapGenerator so it is served at /runbooks/node-memory-swap
rather than existing only in git.

jakman85andClaude Opus 5 79c703bc79 fix(conformance): whole-repo checks audited nested agent worktrees as source
Six discovery sites walked ROOT without pruning dot-directories, so they
descended into .claude/worktrees/agent-*/ — up to 18 full copies of the repo,
created for isolated agent runs and gitignored (.gitignore:43).

The visible half was false FAILs: four ServiceMonitors reported as selecting no
Service, and nine PrometheusRule manifests reported as "under test but not in
the repo", all of them worktree paths. The whole-repo L0 gate was red for
reasons that had nothing to do with authored surface.

The dangerous half is quieter. A check that asks "does anything in the repo
declare X" can be satisfied by a worktree copy instead of real source, so the
same bug that invents failures can also manufacture a pass. That is the reason
to fix all six sites rather than only the ones that happened to be failing.

egress-paths-selected-by-rules already had this fix and documents it (it once
saw 5 CiliumEgressGatewayPolicy objects instead of the 1 authored); this applies
the same dot-directory predicate everywhere else, which skips dot-DIRECTORIES
while still matching dot-FILES such as .sops.yaml.

platform/monitoring/tests/run.sh is the other side of the same failure: its
`--list` reported each manifest once per worktree, and the L0 check compares
that listing against the tree. Both find calls now prune .claude alongside .git.
`--list` returns 21 real pairs where it previously returned them ~19x over.

Verified in the pinned toolbox: L0 --include-scope whole-repo is 21 cases,
0 failures, 0 skips, 0 unwired (was 4 failures, then 1). L1 3/3.

The 18 stale worktrees are all on already-merged branches and remain on disk;
cleaning them up is a separate change and is no longer load-bearing for the gate.

A kubectl jsonpath with {range .data}{@}{end} dumped the unifi Secret's data

constraint I put in every agent brief, broken by my own careless verification
command.

Exposure bounded: 0 commits contain it (git log -S), the capturing scratch file
was shredded, and a repo-wide grep finds nothing on disk. Critically it is not
yet a live credential — the Secret was created two days after the running VMI,
whose volume list is rootdisk and cloudinit only, so the UOSDATA disk was never
attached, install-uos never ran, and the ubuntu account is still locked.

Action recorded with the ordering that matters: rotate console-password BEFORE
recreating the VMI, so the leaked value never becomes valid.

Lesson: checking a Secret's existence never needs its values. Listing .data's
keys or .metadata.name answers the question; dumping .data answers one nobody
asked.

jakman85andClaude Opus 5 14d5ccbadd fix(unifi): pin the MAC — an unpinned MAC is why the guest keeps losing its IP
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
Operator set console-password in the SOPS secret (installer-url deliberately
left as REPLACE-ME, which install-uos handles by printing 'not set yet' and
exiting 0; the uosserver guard exits before it is even read).

Root cause of the lost address, from evidence rather than inference. KubeVirt
generates a fresh MAC per VMI when none is pinned. cloud-init writes
/etc/netplan/50-cloud-init.yaml matching the MAC it saw, and will not rewrite
it while the NoCloud instance-id is unchanged — and that instance-id is
domain.firmware.uuid, stable across restarts by design. So every VMI
recreation handed the guest a MAC its retained netplan did not match, leaving
enp1s0 administratively DOWN, never even attempting DHCP.

What the 2026-09-12 boot log shows, and why it fits: cloud-init's own device
table reads 'enp1s0 | Up: False | Address: .'; there are no apt failures
because the per-instance modules were skipped; yet UOS is installed (6.3 GB of
40 GB) and qemu-guest-agent answers — both of which required working network on
an EARLIER VMI. The MAC is identical between the current VMI status and that
boot log, so it did not change on this boot; the mismatch is against a netplan
written under a previous incarnation.

Pinned to the MAC the current VMI already holds, so nothing changes for this
guest. Combined with the instance-id bump already merged, the next restart
re-runs cloud-init, rewrites netplan against a MAC that is now permanent, and
the interface should come up — and the console password is in place as the
fallback if it does not.

Still unverified from outside: the netplan file's actual contents. That needs
the console the operator can now reach.

jakman85andClaude Opus 5 05881d5a6a fix(conformance): regenerate the three L1 goldens the external-dns change drifted
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
b184a42 made the renderer stamp external-dns.alpha.kubernetes.io/controller:
none on internal services' HTTPRoutes, but three L1 golden fixtures were never
regenerated, so container-workload-render (R-PLAT-02) and egress-class-render
(R-NET-05/06/07) failed. Exactly one line differs in each — the annotation and
nothing else.

WORTH RECORDING: the merge that caused this GATED GREEN. The requirement-scoped
selection did not include R-PLAT-02 or R-NET-05/06/07, so neither check ran. A
later docs-only commit shifted the touched set, selected them, and exposed a
failure the earlier merge had introduced — meaning the gate reported PASS on a
tree it had not actually checked in the relevant place.

That is the same fail-open the whole-repo scope mechanism was built for, except
that mechanism covers L0 only; L1 is still purely requirement-scoped. A renderer
change can therefore drift any L1 golden whose requirements the change does not
happen to attribute. Both affected checks are pure offline renders with no
cluster dependency, so they are cheap to run unconditionally — declaring
scope: whole-repo on the l1-rendering tests looks like the right follow-up.

Also note the checks diff fail-fast: only egress-vpn was reported, while
egress-internet had drifted identically and was never reached.

before the DHCP repoint, but the router returns nothing for those six names, so
the records served nobody and the dependency I asserted did not exist. One
query would have shown it.

Also records the operator's clarifications — Pi-hole is DNS only with the
router still doing DHCP, reverse proxy by hostname rather than a second IP, and
Minecraft staying open — plus the unencrypted-secret fix.

Every other *.sops.yaml in this repo carries sops metadata and ENC[] values;
this one shipped with neither and both fields as literal REPLACE-ME. Two

documented operator step could not work; and Flux would pass the file through
undecrypted and create the Secret with the literal placeholder strings.

Encrypted in place with the repo's age recipient, placeholders intact.
Round-trip verified: sops -d returns installer-url and console-password as
REPLACE-ME, so the operator's workflow is now the normal one — sops the file,
set both values, commit.

Both fields need setting, not just the password: installer-url is also
REPLACE-ME, which I had omitted from the operator instructions.

jakman85 b184a42729 merge: internal services stop advertising themselves in public DNS
Six exposure:internal services published A records into the public Cloudflare
zone answering 192.168.2.20, disclosing the internal subnet, the Gateway VIP
and a full service inventory, and forming a DNS-rebind primitive that is why
the SOHO router strips these answers in the first place.

The renderer now stamps external-dns.alpha.kubernetes.io/controller: none on
every HTTPRoute it renders for an internal service, derived from the exposure
field alone — so a service that omits exposure defaults to internal and is
likewise unpublishable. Established against the deployed v0.21.0's own source,
where the controller check runs before hostname resolution in both configured
sources, then proven live on a throwaway hostname including that adding the
annotation to an existing record triggers the DELETE.

Deletes exactly 12 records: the A and TXT pair for jackett, pihole,
qbittorrent, radarr, semaphore and sonarr. A 39-record recovery baseline is
committed alongside.

Safe to land before the DHCP change, contrary to my earlier caution: the
router returns NOTHING for all six names today, so these records serve nobody
on the LAN, while Pi-hole at 192.168.2.23 already answers for anyone pointed
at it.

The five exposure:public services are untouched. They remain unreachable
publicly, which is a separate problem: the legacy edge at 136.51.115.252
returns HTTP 403 for our hostnames and serves a placeholder certificate, so
nothing is reverse-proxying them today.
2026-09-18 20:50:43 -05:00
jakman85andClaude Opus 5 4080065aa7 feat(dns): exposure: internal can no longer publish a public record
docs/09 R-DNS-03 and schemas/renderer-contract.md both said an `internal`
service renders no public DNS record. Nothing enforced either sentence.
ExternalDNS's `gateway-httproute` source admitted EVERY HTTPRoute on the shared
Gateway, so six `exposure: internal` services — jackett, pihole, qbittorrent,
radarr, semaphore, sonarr — published `<name>.home.keithjackson.dev` into the
public authoritative Cloudflare zone answering with the Gateway VIP
192.168.2.20. That published the internal subnet, the Gateway VIP and a full
service inventory to anyone who could guess a label, and made each of those
names a DNS-rebind primitive — which is why the SOHO router strips RFC1918
answers and LAN clients need per-client dnsmasq overrides to reach their own
services.

THE MECHANISM, established against the DEPLOYED version rather than from
memory. The live prod Deployment runs
registry.k8s.io/external-dns/external-dns:v0.21.0. In v0.21.0,
source/annotations/processors.go IsControllerMismatch() skips a source object
whose `external-dns.alpha.kubernetes.io/controller` annotation is present and
!= its own `dns-controller`, and source/gateway.go applies that check inside
Endpoints() BEFORE any hostname is resolved; source/service.go applies the
identical check, covering the second configured source. catalog/render.py now
emits that annotation on every HTTPRoute it renders for an `internal` service,
derived from `exposure` alone — no per-service list — so a service that omits
`exposure` inherits the internal default and is unpublishable too. Verified
LIVE on prod on a throwaway hostname with no existing record at risk: the
annotated route published nothing, and adding the annotation to a route that
already had a record produced action=DELETE for both its A record and its `a-`
TXT registry entry one ~60s reconcile later, moving nothing else in the zone.

WHY PER-RESOURCE AND NOT A CLUSTER-WIDE OPT-IN FILTER. `labelFilter` is the
stronger default posture and v0.21.0 supports it for both configured sources,
but nine publishing objects here are hand-authored platform/apps manifests with
no `exposure` field, seven of which hold live records (auth, crafty, crafty-mc,
grafana, headlamp, the apex, unifi). An opt-in filter deletes all seven at
once, and whether each should be publicly resolvable is an operator decision
per name. Per-resource exclusion has exactly the blast radius of the defect;
the seven are enumerated in a shrink-only register so the unadjudicated set
cannot grow silently, and the filter stays available as hardening afterwards.

`policy: sync`, `txtOwnerId` and `domainFilters` are UNTOUCHED. Per-resource
exclusion only ever removes an object from this instance's view, so nothing
here makes prod capable of deleting a record it does not own.

WHAT THIS DELETES, and it is not reversible by a revert alone: 12 records — the
A record and the `a-`-prefixed TXT registry entry for each of jackett, pihole,
qbittorrent, radarr, semaphore and sonarr. The zone has no
`*.home.keithjackson.dev` wildcard and `*.keithjackson.dev` does not match two
labels, so each becomes a public NXDOMAIN with no fallback. The complete
pre-state is captured at the authority and committed as a recovery baseline
(.standup-dns/dns-20260914-pre-externaldns-scope.txt), with the restore
procedure for both halves of a record.

MERGE ORDER IS NOT OPTIONAL: feat/pihole-lan-dns-authority must land and be
verified first. Removing these records while the LAN still depends on them,
with the router stripping RFC1918 and no internal authority yet, breaks name
resolution outright.

The five `exposure: public` services are LEFT UNCHANGED and still answer with
the Gateway VIP, so they remain publicly unreachable. That is two open operator
decisions, both written up in platform/externaldns/helmrelease.yaml: what
address they should answer with (136.51.115.252 is the legacy non-k3s stack
serving a placeholder cert, not established as correct for this cluster), and
how to separate them from the non-public names that share the Gateway —
because in v0.21.0 the target annotation is read only from the GATEWAY and a
ListenerSet, never from an HTTPRoute, so a per-service override is not
expressible while they all attach to `shared`. No knob is added for it yet: one
that cannot take effect invites someone to set it and expect one.

Guard: conformance/tests/l0-static/internal-services-publish-no-public-dns, a
whole-repo-scoped L0 static check (no ci/l0.sh stage — the
whole-repo-invariants-wired meta-test forbids one). It asserts both directions
(present on internal, absent on public), the `service`-source half, that the
renderer DERIVES the annotation from `exposure` and cannot emit external-dns's
own claiming value, proves the shipped renderer end-to-end on
internal/public/omitted-field fixtures, and ratchets the non-catalog register.
Proven to fail on the pre-fix tree (9 of 53 assertions, naming all six
services) and pass after (56/56).

Schema 1.6.0 -> 1.7.0: no field changes, a mapping change to `exposure`.

jakman85andClaude Opus 5 16c6234696 feat(monitoring): alert when egress steering goes stale, not just when tun0 dies
`VPNTunnelDown` goes green the instant a tun0 exists, which is not the same as
vpn-class pods having egress: Cilium caches (egress IP, egress ifindex) at first
resolution, so after a reconnect the BPF egress map points at a destroyed
interface and the packets are dropped while tun0 looks perfectly healthy. Dev sat
in exactly that state for ~80 minutes with nothing alerting.

Two rules close it:

* VPNEgressSteeringStale (critical, for: 15m) — fires when the live tun0 was
  re-created more times in the last hour than the gateway node's `egress-uplink`
  label changed, i.e. Cilium was never told about a reconnect.
* VPNEgressUplinkLabelMissing (warning, for: 30m) — the watchdog for the
  watchdog: a gateway node whose uplink label never reaches kube-state-metrics is
  a cluster where the rule above is inert.

Both gated on a gateway node existing, reusing `VPNTunnelDown`'s
`kube_node_labels` guard — a cluster with no gateway cannot be made to fire them.

The direct label-vs-map comparison is NOT available and nothing was invented to
pretend otherwise: no `cilium_*`/`hubble_*` series exist on either cluster (the
cilium-agent exposes no metrics port, there is no ServiceMonitor), and Cilium OSS
publishes no series carrying egress-map contents at all — the map is readable only
via `cilium-dbg bpf egress list`. PromQL also cannot compare a metric value (the
live ifindex) against a number inside a label value, so the level-triggered
equality test is not expressible; the same invariant is counted over a window
instead. Both limits, and the textfile-collector/black-box-probe routes that would
lift them, are written down in the rule comments and the DECISIONS-LOG.

`egress-uplink` added to kube-state-metrics.metricLabelsAllowlist in the same
kustomization, because without it the first rule has nothing to compare.

Verified read-only against LIVE prod (port-forward + /api/v1/query), rendered expr
extracted from `kubectl kustomize platform-config`: empty when healthy; empty when
evaluated at a timestamp before prod had a gateway node; and FIRING when pointed at
a label that genuinely failed to follow prod's real 128 -> 129 tun0 flap earlier
today. Nothing on prod was disturbed to produce that.

## Transition: generic-CI-now → Gitea-Actions-after-Gitea-is-up
## Transition: COMPLETE (2026-09-29)
Per [`CONTRIBUTING.md`](../../../home-network-k3s/CONTRIBUTING.md) and
[`docs/05` §"local bootstrap → self-hosted Gitea"](../../../home-network-k3s/docs/05-gitops-and-delivery.md):
This section used to describe a migration as pending. It has happened. Gitea is live at
`gitea.home.keithjackson.dev`, the runner `incluster-dind` is registered and online, and
`gate.yml` runs on every PR.
1. **Now (interim):** there is **no remote git host** on this network. This workflow file is dormant —
but the **identical gate runs locally today** via `make -C ci gate` (R-TEST-02). Development is
local feature-branch → `main`, the gate enforced by convention + the local runner.
2. **Gitea comes online early** (one of the first services onboarded) at `gitea.home.keithjackson.dev`.
3. **CI moves to Gitea Actions:** this workflow activates unchanged. The only operational steps are
enabling a Gitea Actions runner and setting `vars.CLUSTER_AVAILABLE=true` +
`secrets.CONFORMANCE_TRIGGER_KUBECONFIG` once a dev/test cluster exists. PRs then become the
**platform-enforced** merge gate — the same no-work-in-main rule, now enforced by machine.
**What took a month to notice:** the migration was recorded as done on 2026-08-31 without
anyone checking the platform. In reality `main` had **no branch protection** and **zero
runners were registered** until 2026-09-29. Every "the gate enforces this" statement in
between rested on an assertion nobody verified. PR #1 — the first pull request this
repository ever had — sat `pending` for 30.6 minutes because nothing existed to run it.
So: **do not read this file, or the DECISIONS-LOG, as evidence about the live platform.**
Query the API. `infra/gitea/` holds the scripts and the measured state.
Still genuinely outstanding: `vars.CLUSTER_AVAILABLE` and
`secrets.CONFORMANCE_TRIGGER_KUBECONFIG` are unset, so L2/L3 conformance does not run in
CI. That is a real coverage gap, not a phase.

# RECOVERY BASELINE — the COMPLETE Cloudflare record set for zone `keithjackson.dev`
# as it stood IMMEDIATELY BEFORE feat/externaldns-scope-public-only is applied.
#
# WHY THIS FILE EXISTS. The branch that adds it changes which resources ExternalDNS considers,
# and ExternalDNS runs `policy: sync` — a record whose source stops matching is DELETED, not
# merely left alone. That is a one-way, outward-facing operation against a live authoritative
# zone, so the pre-state is captured and committed BEFORE the change lands, and any record the
# reconcile removes can be restored by hand from this file. It is the same discipline as
# dns-before.txt / dns-verify.txt / dns-post-l2.txt beside it, applied to a destructive-capable
# change rather than to a migration.
#
# CAPTURED 2026-09-14 from the Cloudflare API (GET /zones/<id>/dns_records, all pages) using the
# SOPS-encrypted token in platform/externaldns/cloudflare-api-token.sops.yaml. Read at the
# AUTHORITY, not through a resolver: 1.1.1.1 served stale answers for minutes after the
# 2026-09-13 apex flip and must not be trusted for this. `dig` is on the host but NOT in the
# devcontainer, which has previously produced false "no records" readings — the API is the only
# reading that is both complete and authoritative.
#
# FORMAT (5 fields, `|`-separated) — wider than the sibling files on purpose: a restore needs the
# TTL and the proxy flag, not just the value.
#
# <type>|<name>|<content>|<ttl>|<proxied>
#
# ttl 1 = Cloudflare "Automatic". proxied false = DNS-only (grey cloud), which every record here
# is; a restore that flips one to proxied would put Cloudflare's edge in front of a LAN address.
#
# 39 records. 36 of them are ExternalDNS-managed (18 A + their 18 `a-`-prefixed TXT registry
# entries), every one registered `external-dns/owner=prod` — i.e. THIS cluster owns them, which
# is why this cluster's reconcile is able to delete them. The remaining 3 belong to the legacy
# non-k3s stack and carry NO TXT registry entry, so no owner id claims them and ExternalDNS
# cannot touch them regardless of what this branch does:
#
# *.keithjackson.dev -> 136.51.115.252 legacy stack (the zone wildcard)
# brickbreak.keithjackson.dev -> 20.236.242.14 unrelated, off-prem
# dev.brickbreak… -> 20.236.242.14 unrelated, off-prem
#
# NOTE there is NO `*.home.keithjackson.dev` wildcard in the zone any more (the comment in
# clusters/prod/kustomization.yaml still says the zone has both wildcards; it does not, as of
# this capture). A single-label wildcard does not match two labels, so `*.keithjackson.dev` does
# NOT cover `<svc>.home.keithjackson.dev`: when a specific `<svc>.home` record is removed, that
# name goes to NXDOMAIN publicly rather than falling back to the legacy IP. That is the intended
# end state for `internal` services and it is also precisely why Pi-hole must already be
# answering the LAN authoritatively before this branch merges.
#
# WHICH OF THESE THIS BRANCH DELETES — the 12 rows for the six `exposure: internal` catalog
# services (jackett, pihole, qbittorrent, radarr, semaphore, sonarr): each one's A record and its
# `a-`-prefixed TXT registry entry. Nothing else. Verified live on prod against the deployed
# v0.21.0 with a throwaway hostname before any of this was authored: adding the annotation to an
# HTTPRoute that already had a published record produced
# `action=DELETE record=... type=A` and `action=DELETE record=a-... type=TXT` one reconcile
# interval (~60s) later, and nothing else in the zone moved.
#
# TO RESTORE ONE ROW BY HAND (both halves, or ExternalDNS will not recognise the record as its
# own): recreate the A record with its value/ttl/proxied from this file, then recreate the
# matching `a-<name>` TXT with its content VERBATIM — the `heritage=…,external-dns/owner=prod,
# external-dns/resource=…` string is what re-establishes ownership. An A record restored without
# its TXT is unowned and will not be reconciled; a TXT restored with a wrong `resource=` value
# points the registry at a source object that does not exist.

# CLAUDE.md — how work lands in this repo
Read this before doing anything durable. It is the delivery contract for AI coding
sessions and agents. `DECISIONS-LOG.md`'s last entry is the current PM handoff and
takes precedence on *what* to work on; this file governs *how* it lands.
## 1. Never push to `main`. Ever.
Every durable change reaches `main` exactly one way:
branch -> push the branch -> open a PR -> CI gate green -> human approval -> merge
There is no other path. Specifically:
- **Do not `git push origin main`.**
- **Do not `git push origin HEAD:main`.** Same thing wearing a hat.
- **Do not merge your own PR.** A human approves and clicks merge.
- **Do not `kubectl apply` / `edit` / `patch` a durable change.** Flux reconciles `main`;
anything applied by hand is drift that the next reconcile reverts or, worse, adopts.
> **Many runbooks under `runbooks/` still say `git push origin main` IS the deploy.**
> That wording is **stale** — it predates the PR flow. It describes what Flux does
> (main is what the cluster follows), not what you are permitted to do. Honour this
> file, not that line. Fixing those runbooks is tracked work.
## 2. Enforcement is currently WEAKER than this rule. Follow the rule anyway.
Verified against the live Gitea on 2026-09-29:
| Expected | Actual |
|---|---|
| `main` protected, direct push rejected | **No branch protection.** `protected: false`, `user_can_push: true` |
| PR blocked until the gate passes | **`enable_status_check: false`**, `status_check_contexts: []` |
| Gate runs on every PR | **Fixed 2026-09-29.** Runner `incluster-dind` is online; `gate / gate (pull_request)` runs and passes in ~1m30s–2m |
| Approval required before merge | **`required_approvals: 0`** |
So nothing mechanically stops you from pushing to `main` right now. **That is a gap
being closed, not permission.** `DECISIONS-LOG.md` (2026-08-31) claimed the gate was a
"required status check" with a runner online; neither was true, which is how this went
unnoticed for a month. The runner half is now genuinely fixed and observed green. The
protection half is not — see `infra/gitea/`.
**Consequence for you:** CI now runs, but it does not yet *block* anything. Always run
the toolbox gate yourself and quote its numbers. Never describe a PR as "green" on the
strength of a check you have not seen report — and note that a **skipped** Gitea job
reports as `success`, so a green tick is not by itself evidence that anything ran.
## 2b. Never infer platform state from this repository
**This repo is not evidence about the live platform.** Neither is `DECISIONS-LOG.md`.
Both describe what someone believed at the time of writing, and both have been
confidently wrong for a month at a stretch.
On 2026-09-29 the log stated the merge gate was a required status check with a runner
online. The API said `branch_protections: []` and **zero** runners. Everything downstream
of that belief — "the gate enforces this", "your push would be rejected", "CI covers it" —
was wrong, and nothing in the tree could have revealed it, because the tree was the source
of the error.
**So, before asserting that any gate, protection, runner, secret, or workload is in a
given state: query the thing itself.**
| Claim about... | Check |
|---|---|
| branch protection / required checks | `GET /api/v1/repos/{owner}/{repo}/branches/main` |
| a runner exists | `GET /api/v1/admin/actions/runners` |
| CI actually ran | the commit's `/statuses` — and read the **description**; a *skipped* Gitea job reports `success` with "Has been skipped" |
| a workload / Secret / env | `kubectl --context k3s-prod ...` (read-only is fine for agents) |
| Flux applied your commit | compare `.status.lastAppliedRevision` against the GitRepository's artifact revision |
Quote the measured field, not the prose. If you cannot measure it, say so explicitly —
"unverified" is a legitimate report, and a far better one than a confident guess that
matches the docs.
**A green tick is not proof anything ran.** Read what actually executed.
## 3. Gate before you push
./infra/devcontainer/dev.sh run bash -c './ci/gate.sh'
Exit codes are a contract — do not flatten them:
| rc | Meaning |
|---|---|
| 0 | PASS |
| 1 | BLOCKED — something failed |
| 3 | UNDETERMINED — a stage did not run. **Never report this as green.** |
`spec-immutability` reaches rc 3 whenever the sibling spec repo is not checked out
beside this one; that single skip is expected and tolerated. Any *other* skip is a
real gap in your run.
**Never gate on the host.** `promtool` and `kustomize` are not on the host `$PATH`,
so checks SKIP and you get a false rc 3. Only the pinned toolbox result counts.
### Running the gate from a git worktree
Two unrelated failures, both with known workarounds — put both in any agent brief:
1. **`dev.sh` refuses to start:** `infra/ansible/.cache/prod.kubeconfig` is untracked
and exists only in the main checkout. Do **not** copy it (it is a credential).
Use `DEV_KUBECONFIG=/dev/null` — the gate contacts no cluster, so L2/L3 scaffold-skip
normally.
2. **Every `git` call inside the container fails:** a worktree's `.git` is a pointer to a
gitdir outside the mounted root. `dev.sh` takes no extra-mount flag, so inject one via
the `ENGINE` hook — a shim that intercepts `run` and re-execs
`podman run -v /path/to/main/.git:/path/to/main/.git:ro "$@"`. A traceback in
`tracked_files()` is this bug, not a broken tree.
## 4. Branch naming
Use `feat/`, `fix/`, `docs/`, `chore/`. Note that `.gitea/workflows/gate.yml`'s **push**
trigger lists `feature/**` — not `feat/**` — so branch pushes get no fast-feedback run.
The `pull_request` trigger fires regardless of branch name, so the PR gate is unaffected.
## 5. Cluster access
`kubectl` does not work on the operator workstation; the toolchain lives only in the
pinned container. Always name the context explicitly:
./infra/devcontainer/dev.sh run bash -c 'kubectl --context k3s-prod get nodes'
`dev.sh` merges both clusters and picks a current-context **per invocation**; that
default has already changed once. Never rely on it. Do not run two `dev.sh`
invocations concurrently.
**Mutating `kubectl` and `flux reconcile` are operator actions, not agent actions.**
## 6. Secrets
- **Never `sops -d` a file into a terminal, a log, or a transcript.**
- **Never print a Secret's `.data`/`.stringData`** when checking whether it exists —
list key names or object names only. A password has been leaked into a transcript
this way before.
- Encrypted files are `*.sops.yaml` or live under `secrets/`. The root `.sops.yaml` is
the single creation-rules file; do not add a second one in a subtree.
- A short-lived credential (e.g. a plex.tv claim token, ~minutes) cannot survive the PR
flow. Do not design around committing one — read the expiry from the issuing page and
treat a burnt token as free to retry.
## 7. Before you finish
Append a handoff entry to `DECISIONS-LOG.md` describing what you changed, what you
verified, and what you did **not** verify. State gaps plainly — an honest
"UNVERIFIED" is worth more than an optimistic "green", and this repo has already been
burned by the difference.

## 2026-09-12 — The silent-gateway outage now has an alert, and the direct signal turned out not to exist (branch `feat/egress-gateway-staleness-alert`)
Hand-off item 4 from the section above: *"A silent gateway outage still has no alert… nothing
watches the invariant `egress-uplink` label == `cilium-dbg bpf egress list`'s Egress Ifindex."*
Closed, as far as Prometheus can close it — and the part that cannot be closed is recorded here
rather than papered over with a plausible-looking metric name.
### The direct signal is not available, verified rather than assumed
The invariant wants the BPF egress map's contents. They are not in Prometheus, for two independent
reasons, both checked read-only against live prod:
| check | result |
|---|---|
| `{__name__=~"cilium.*egress.*"}`, `cilium_drop.*`, `hubble_drop.*` | **empty vector** — no `cilium_*`/`hubble_*` series exist at all |
| container ports on the cilium DaemonSet | `health=9879`, `peer-service=4244` — **no metrics port**; only the operator has `operator-prometheus-serve-addr :9963` |
| `kubectl get servicemonitors -A \| grep -iE 'cilium\|hubble'` | none — Hubble/Cilium metrics export is still the open TODO in `platform/cilium/helmrelease.yaml` |
So `HubbleDeniedFlowSpike` cannot fire today either; that is a separate, pre-existing gap, noted
and left alone. And even with agent metrics turned on, **Cilium OSS publishes no series carrying
egress-map contents** — the map is readable only through `cilium-dbg bpf egress list`, a CLI over
the BPF map. Nothing was invented to fill the hole.
What node-exporter *does* export is the live tun0 **ifindex as a metric value**:
`node_network_iface_id{device="tun0"}` = `129` on `k3s-prod-3`. Read-only on the live cluster, all
three agree right now:
```
node label homelab.keithjackson.dev/egress-uplink = 10.150.192.86-129
node-exporter node_network_iface_id{device="tun0"} = 129
bpf map Egress IP 10.150.192.86 / Egress Ifindex 129 (all 16 rows, 4 vpn-class pods)
```
(The map on the two NON-gateway agents reads `Egress IP 0.0.0.0 / Ifindex 0` with
`Gateway IP 192.168.2.12` — only the gateway node resolves the interface. Worth knowing before
debugging the wrong agent.)
### PromQL cannot express the equality test — so the invariant is counted instead
The label's value is `<addr>-<ifindex>`; the live ifindex is a metric VALUE. PromQL has no
label-to-number conversion, so `label == value` is **not expressible**, and there is no
level-triggered form of this comparison. What is expressible is the same invariant counted over a
window: **the published label must change at least as often as tun0 is re-created.**
```promql
(
changes(max(node_network_iface_id{device="tun0"})[1h:1m])
>
(count(count_over_time(max by (label_homelab_keithjackson_dev_egress_uplink) (
kube_node_labels{label_homelab_keithjackson_dev_egress_uplink!=""})[1h:1m])) - 1)
)
and on()
(count(kube_node_labels{label_homelab_keithjackson_dev_egress_gateway="true"}) > 0)
```
`count(count_over_time(max by (<label>) (…)[1h:1m]))` is the number of DISTINCT label values in the
window. The `max by (<label>)` wrapper is load-bearing: it aggregates away `pod`/`instance` so a
kube-state-metrics restart is not read as a label change. Both sides reduce to a single unlabelled
series, which is why `and on()` joins — the same reason `VPNTunnelDown` needs `on()`.
### Proof it evaluates — executed against prod's Prometheus, port-forward + `/api/v1/query`
There is no promtool in this repo, so query execution IS the verification. The **rendered** expr was
extracted from `kubectl kustomize platform-config` output and run verbatim:
| state | query | result |
|---|---|---|
| healthy, now | rendered `VPNEgressSteeringStale` | `[]` — not firing |
| **no gateway node** (`@ 1789245000`, before prod's stand-up: no tun0 series, no labels) | same expr | `[]` — cannot fire |
| **stale**, constructed from real data | same expr with the already-exported `egress-gateway` label substituted for `egress-uplink`, window 3h | **`1` — FIRES** |
| same expr, window 1h | | `[]` |
The stale case is honest and cost prod nothing: prod's tun0 really did go **128 → 129** ~2.5h
earlier when it moved to PIA `.135`, and the `egress-gateway` label really did *not* follow it
(`changes(...[3h:1m])` = 1, distinct label values = 1 → `1 > 0`). That is bit-for-bit the shape of
a label that missed a flap. The healthy counterfactual is the one thing left as reasoning rather
than a query: over that same 3h the REAL `egress-uplink` label held two values
(`10.72.192.7-128`, then `10.150.192.86-129`), giving `1 > 1` = false. It could not be queried
because the label was not exported yet — which is the next point.
Supporting queries, also live: the distinct-value idiom returns **1** for a label that held still
over the window and **2** for one whose value changed inside it (node 3's `egress-gateway` label
over 12h, which went `""` → `"true"` at stand-up); the gateway guard returns 1; subquery +
`changes()` returns 0/1/1/1 over 15m/3h/6h/12h as the flap history requires.
### Behaviour at the edges
- **No gateway node:** three independent reasons it cannot fire — no tun0 series, no uplink label,
and the `kube_node_labels` guard `VPNTunnelDown` already established. Verified at a past
timestamp when prod genuinely had no gateway. This matters: `VPNTunnelDown` fired permanently on
prod for exactly this reason and had to be retrofitted.
- **Convergence:** the up-script rewrites the label within seconds of a connect, worst case ~5m
(its 30 × 10s kube-API retry budget on a cold boot, when the API is not up yet). The condition is
true during that gap, so `for: 15m` — comfortably past the 2-minute timer and the 5-minute retry
budget — is what keeps a normal reconnect quiet.
- **Bounded, deliberately:** a missed flap alerts from +15m to +1h, then RESOLVES even if egress is
still dead. An unbounded critical on `email-critical` is the worse failure for this repo, and 15
minutes still beats 80. A level-triggered version needs the map's ifindex as a real metric — the
node-exporter textfile collector route, still open.
### The second rule exists because the first one fails OPEN
`VPNEgressSteeringStale` needs `egress-uplink` in kube-state-metrics. Without it the comparison
degrades to an empty vector and alerts nothing — so `VPNEgressUplinkLabelMissing` (warning,
`for: 30m`) watches the precondition: a node labelled `egress-gateway=true` with no `egress-uplink`
label visible. Live right now it returns **1**, correctly: the KSM allowlist extension is in this
same branch and not yet deployed. It self-clears on the first reconcile, and `for: 30m` covers the
kube-state-metrics roll. The rule and the allowlist are in the same Flux kustomization on purpose.
`kube-state-metrics.metricLabelsAllowlist` now reads
`nodes=[homelab.keithjackson.dev/egress-gateway,homelab.keithjackson.dev/egress-uplink]` — a label
DIMENSION on the same 3 `kube_node_labels` series, not new series, on exactly one node.
### Rejected, with reasons
- **A black-box egress probe** is the most honest signal — it is the only one that answers "does a
vpn-class pod's traffic actually leave via the tunnel?" and the only one that catches "the label
was written and Cilium ignored it anyway". Rejected **for now**: there is no blackbox-exporter and
no probe CronJob in this repo, so it means a new always-on component (itself vpn-class, itself an
alerting surface, itself dependent on a third-party endpoint) — and it could not have been
verified on prod today. It remains the right next step.
- **A node-exporter textfile metric from the re-steer script** (hand-off item 4's own suggestion) is
the only route to a true level-triggered label-vs-MAP comparison. It needs a textfile directory
mounted into the node-exporter DaemonSet plus an Ansible change applied on a prod node — neither
of which this branch could execute or verify. Left open, now with the reason recorded.
- **`absent(node_network_receive_bytes_total{device="tun0"})`-style presence checks** — that IS
`VPNTunnelDown`, and it is exactly the blind spot: green while steering points at a dead ifindex.
### Left for the operator / not settled here
1. **The rules are unproven in the firing sense.** The expressions evaluate against live prod data
and the stale branch was exercised with a real flap, but no alert has actually reached
Alertmanager or the inbox. `conformance/tests/l3-fault-injection/vpn-killswitch` stops and
restarts the tunnel and is the natural place to assert `VPNEgressSteeringStale` stays quiet
through a healthy reconnect; the alerting L3 test with the SMTP sink is where a fired-and-emailed
proof would come from. Neither was fired at prod unasked.
2. **`HubbleDeniedFlowSpike` cannot fire** — no cilium/hubble metrics are scraped on either cluster.
Pre-existing, orthogonal, and the same TODO in `platform/cilium/helmrelease.yaml` blocks it.
3. **Window vs. stickiness** is a judgement call, not a measurement: 1h chosen so a missed flap
alerts for ~45 minutes. If the operator would rather have a sticky alert that needs manual
acknowledgement, that is the textfile-collector design, not a tweak to this one.

---
## 2026-09-18 — VERIFIED: internal services no longer advertise themselves publicly
The R-DNS-03 disclosure is closed for the `internal` tier. Confirmed at the authority
(`betty.ns.cloudflare.com`, not a cache):
| name | public DNS | via Pi-hole `.23` |
|---|---|---|
| sonarr, radarr, qbittorrent, jackett, semaphore, pihole | **GONE** | 192.168.2.20 |
| plex, gitea, seerr, keycloak, nextcloud | 192.168.2.20 (untouched, as designed) | — |
So split-horizon now genuinely exists: the names resolve internally and are absent externally, which
is what `docs/09-dns-and-ingress.md` specified all along. The internal subnet, the Gateway VIP and six
service names are no longer publicly enumerable, and the DNS-rebind primitive is gone for those six.
**A correction to my own sequencing.** I had insisted this could not land until the operator repointed
DHCP, on the grounds that removing public records would break LAN resolution. That was wrong, and
measuring it took one command: the SOHO router at 192.168.2.1 returns **nothing** for all six names, so
the public records were serving nobody on the LAN. The dependency I asserted did not exist. Landing it
early closed a security finding a day sooner than my own plan allowed.
**Operator clarifications recorded** (theirs, 2026-09-18):
1. Pi-hole is **DNS only** — the SOHO router remains the DHCP server. Nothing in the Pi-hole change
touches DHCP; it exposes udp/53 and tcp/53 and no DHCP feature is enabled. The remaining action is
on the router: hand out `192.168.2.23` as the DNS server, ideally with a public resolver secondary
so a Pi-hole outage degrades to "internal names stop resolving" rather than "the LAN loses DNS".
2. **Reverse proxy by hostname is the accepted design; a separate IP is overkill.** So no second
Gateway and no second LoadBalancer address — the existing Gateway already distinguishes by Host/SNI.
Per-service public DNS targeting, if wanted, therefore goes through `DNSEndpoint` objects plus the
`crd` source rather than a second Gateway carrying a target annotation.
3. Minecraft stays open with no whitelist — accepted.
**Still open, and it is a fact about the WAN, not a repo decision.** The five `public` services have no
working public path at all: `136.51.115.252` returns **HTTP 403** for `gitea.home.keithjackson.dev` and
presents a placeholder certificate (`CN=%D`), so nothing reverse-proxies these names from outside today.
Either the WAN forwards 80/443 to the Gateway at `192.168.2.20` — in which case their records should
point at the WAN address — or those five should be re-declared `internal`, because `exposure: public`
currently asserts something untrue.
**Also fixed:** `apps/vms/unifi/unifi-uos-installer.sops.yaml` had been committed **unencrypted** with
both fields as literal `REPLACE-ME`, unlike every other `*.sops.yaml` here. `sops <file>` would have
failed with "sops metadata not found", and Flux would have created the Secret containing the
placeholder strings. Encrypted in place, round-trip verified. Both fields need setting, not just the
password — I had omitted `installer-url` from the operator instructions.
---
## 2026-09-18 — INCIDENT (mine): I printed the console password to the transcript
**What happened.** Verifying that the `unifi-uos-installer` Secret had reached the cluster, I ran a
`kubectl get secret -o jsonpath` that included `{range .data}{@}{end}`. That dumps the whole `data`
map, so the base64 of `console-password` was printed to the session transcript. This is precisely the
constraint I have written into every agent brief in this repo — *never print decrypted secrets* — and I
broke it myself with a careless jsonpath while checking someone else's work.
**Exposure, stated precisely rather than minimised or inflated:**
- The value reached the session transcript, which I cannot scrub.
- It did **not** reach git: `git log --all -S<value>` returns **0 commits**.
- The scratch file that captured it (`tasks/*.output`) was shredded; a repo- and scratch-wide grep for
the string now returns nothing on disk.
**Why it is not yet a working credential — the one thing that limits this.** The Secret was created
`2026-09-14T07:26:43Z`; the running VMI was created `2026-09-12T20:48:30Z`, and its live volume list is
only `rootdisk` and `cloudinit` — **the `UOSDATA` disk is not attached to the running VMI at all**. So
the guest has never read the Secret, `install-uos` has never executed, and the `ubuntu` account remains
locked. The leaked string authenticates nothing today. It would only become valid when the VMI is
recreated against the new spec.
**Required action, and the ordering matters:** rotate `console-password` in the SOPS Secret **before**
recreating the VMI. Then the leaked value never becomes a working password anywhere:
sops apps/vms/unifi/unifi-uos-installer.sops.yaml # set a NEW console-password
git commit && git push # let Flux update the Secret
kubectl -n unifi delete vmi unifi # only after the rotation has landed
**The lesson, generalised.** Reading a Secret to check *existence* never requires reading its
*values*. `-o jsonpath='{.metadata.name}'` or listing `.data`'s KEYS answers "did it land?"; dumping
`.data` answers a question nobody asked. Every previous secret check in this session used a
keys-only or boolean form — this one regressed because I appended a convenience field to an
otherwise-safe command without re-reading what it expanded to.
## 2026-09-18 — Two fail-open holes in the gate itself: nested worktrees, and L1 never running
Three pieces of work, one theme: the gate was reporting green over things it had not checked.
### 1. `runbooks/node-memory-swap.md` — the procedure the operator asked for
Keith has a matched 32 GB pair to install and asked which node needs it. **`k3s-prod-1`**: `DIMM1` is a
Micron `8ATF2G64HZ-3G2E1` (16 GB, DDR4-3200, 1Rx8), `DIMM3` a `16ATF2G64HZ-2G6E1` (16 GB, DDR4-2667,
2Rx8). Capacity is correct; the pair runs at the slower 2667. Nothing is faulty. `k3s-prod-3` is a
matched Crucial pair.
The runbook front-loads the go/no-go checks because this is the awkward node to lose: 24 Longhorn
replicas, one of three etcd members (drain leaves quorum at 2 of 3, no further margin), and its
rebuilds are the load that starved etcd once. A BLOCKED drain is treated as the safety property
working, never something to force past.
Three things I had written and then removed, because they were not true:
- **`EtcdIsVoter` does not exist in this cluster.** I had an assertion built on it; it appears nowhere
in the repo. The house check is `curl http://127.0.0.1:2381/metrics | grep etcd_server_has_leader`
(`runbooks/node-down.md:93`).
- **`node-drain-policy` is not pinned** in `platform/longhorn/helmrelease.yaml`. The runbook has the
operator READ the live Setting and set it before draining rather than assuming the chart default —
that Setting is the entire safety story for 24 replicas.
- I had written "rebuild concurrency is deliberately 1". That is the purge/restore limits, not replica
rebuild — the same 5-vs-1 confusion already corrected once in `longhorn-degraded.md`.
Verification hinges on **`Configured Memory Speed`**, not `Speed`: a matched 3200 pair being clocked
down still reports `Speed: 3200 MT/s`, so matched part numbers alone do not prove the swap worked.
Also recorded: the `node-health` artifacts de-duplicate DIMM part numbers, so they can prove "two
different modules" but cannot distinguish one module from two identical ones — verification collects
`dmidecode` live. **Node 2's inventory remains stale and self-contradictory** (documented as the only
single-DIMM node at 16 GB, yet reporting ~31.1 GiB) and needs re-inventory before anyone claims
three-way symmetry. This is NOT the §0b "do not buy RAM" case, which was an EFI memattr kernel bug.
### 2. The whole-repo L0 checks were auditing 18 copies of the repo
Six discovery sites walked `ROOT` without pruning dot-directories, so they descended into
`.claude/worktrees/agent-*/` — full repo copies from isolated agent runs, gitignored at
`.gitignore:43`.
The visible half was false FAILs: four ServiceMonitors "selecting no Service", nine PrometheusRules
"under test but not in the repo", every path a worktree path. The whole-repo gate was red for reasons
with nothing to do with authored surface.
The dangerous half is quieter, and is why all six were fixed rather than only the failing ones: a check
asking *"does anything in the repo declare X"* can be satisfied by a worktree copy instead of real
source. The same bug that invents failures can manufacture a pass.
`egress-paths-selected-by-rules` already had the fix and documents hitting it (it once saw 5
`CiliumEgressGatewayPolicy` objects instead of the 1 authored). Its dot-directory predicate is now
applied everywhere, plus both `find` calls in `platform/monitoring/tests/run.sh`, whose `--list`
reported each manifest once per worktree — 21 real pairs where it had been returning them ~19x over.
### 3. L1 rendering never ran on a requirement-scoped gate — closed, with the incident reproduced
`ci/l1.sh` has passed `--include-scope whole-repo` since it was written, with a comment saying no L1
test declared the scope yet and it was wired ahead of time. Nothing ever declared it, so **the entire
L1 rendering layer only ran when a touched path happened to attribute R-PLAT-02, R-NET-01 or
R-NET-05/06/07.**
All three L1 tests now declare `conformance.home.k3s/scope: "whole-repo"`. The justification is one
shared code path — `catalog/render.py` against `schemas/servicedefinition.schema.json` — which
requirement-scoped selection cannot see.
The 2026-09-04 external-dns merge is the proof, reproduced rather than asserted.
`ci/touched-requirements.sh` attributes `platform/externaldns/helmrelease.yaml` to R-ENV-02,
R-OBS-01/02/04, R-STATE-03 and R-TEST-01/02/03/04 — **none** of the rendering requirements — yet that
change added `external-dns.alpha.kubernetes.io/controller: none` to the rendered output of all three
goldens. Measured with `--print-selection`:
| selection for that change | L1 tests selected |
|---|---|
| requirement-scoped only (the 2026-09-04 behaviour) | **0** |
| with `--include-scope whole-repo` (how `ci/l1.sh` invokes it) | **3** |
### 4. …which exposed two defects in the meta-check that guards all of this
Declaring the scope at L1 made `whole-repo-invariants-wired` (R-TEST-03) fail, and it was right to
change behaviour — but for the wrong reason, and it could not say so:
- **It was layer-agnostic where the design is layer-bounded.** It compared *every* scope-declaring dir
against an `--layer l0` selection, assuming only L0 tests would ever declare the scope — while
`ci/l1.sh` was written from the opposite premise, that a whole-repo invariant could appear "at any
layer". So it blamed the union for correctly excluding another layer. Now partitioned by layer, with
the L1 selection and L1 leakage assertions added — which is what makes the L1 declaration
load-bearing instead of decorative.
- **Every assertion in it failed silently.** The idiom was `<test>` on one line, `chk $?` on the next,
under `set -euo pipefail` — so a false test aborted the script *before* `chk` could print. The real
failure I hit emitted 26 `ok` lines, rc=1, and no message. All 12 sites now capture the status
(`chk $arc`), proven by forcing `MIN_DECLARED=999`: the failure prints its full diagnostic and the
run continues to the remaining assertions.
A meta-check that cannot report why it failed is worse than no meta-check, because the silence reads
as a tooling glitch rather than a finding.
### Gate
Offline `l0,l1,meta --include-scope whole-repo` in the pinned toolbox: **25 tests, 0 failures, 0
errors, exit 0**. L0 whole-repo went 4 failures → 1 → 0 across the two fixes;
`whole-repo-invariants-wired` now runs 35 assertions. Host runs report one skip because `promtool` is
not on `$PATH` there — the toolbox run is the real result, and that difference is worth remembering
before trusting a host-only gate run.
### PM HANDOFF
Open, in the order I would take them:
1. **The memory swap is a free R-STATE-02 proof.** `node-loss` is Phase 7's last exit item and is still
proven only on the decommissioned dev cluster. The swap is a planned, supervised single-node loss on
prod — exactly the event R-STATE-02 describes. Capturing evidence during it costs nothing extra;
manufacturing the event later costs a second maintenance window.
2. **Node 2 DIMM re-inventory** — blocked on the vault become password for `node_health`. Ansible only;
never `ansible-inventory --list` (it prints decrypted vault values).
3. **Workstation DNS, one sudo command.** `/etc/dnsmasq.d/10-home.keithjackson.dev.conf` contains
`local=/home.keithjackson.dev/` plus `address=/.home.keithjackson.dev/192.168.1.53` — the whole zone
hardcoded to the decommissioned dev cluster, with forwarding forbidden so no upstream could correct
it. That is one root cause for both the sonarr failure and `gitea` not resolving. Pi-hole answers
correctly (`gitea` → `192.168.2.20`); only this file is wrong. Correction to an earlier claim of
mine: there is no separate `20-prod.*` file — it is a replace of this one file. Router DHCP option
6 → `.23` is the fix that makes it unnecessary per-machine.
4. **UniFi guest has no IP** — needs console access; `cat /etc/netplan/*.yaml` is the confirming command.
5. **Five `public` services have no working public path** — waiting on WAN forwarding, which Keith has
said is deliberately not ready.
6. **18 stale agent worktrees** on already-merged branches remain on disk. No longer load-bearing for
the gate; cleaning them up is cosmetic and should check each for uncommitted work first.
7. Backlog cherry-picks: `feat/egress-gateway-staleness-alert`, two `rescued/*` fixes, 103 unmapped
paths, and two rendered manifests nothing applies (the keycloak one would stand up a conflicting
instance).
## 2026-09-19 — Overnight: the backup alert was crying wolf, and 49 app manifests were gated by nothing
Worked autonomously while the operator slept. One theme again: things that reported green, or red, over
something other than what they claimed to measure.
### 1. VeleroNoRecentBackup was firing CRITICAL over backups that protected everything
`velero-daily-20260919030041`: **PartiallyFailed, 3079 of 3079 items backed up, 2 errors** — both
`PodVolumeBackups` for the emptyDir `plugins` + `scratch` volumes of a
`homepage-default-kopia-maintain-job-…` pod. Velero runs transient kopia repository-maintenance Jobs in
its own namespace, one per BackupRepository; under `defaultVolumesToFsBackup: true` it tries to
fs-backup their volumes, the Job finishes, the pod disappears mid-backup, and the PVB fails. Four such
failures had accumulated.
Nothing real was ever missed. But `PartiallyFailed` does not advance
`velero_backup_last_successful_timestamp`, so the alert guarding R-STATE-03 fired nightly over Velero
cleaning up after itself. **An alert that cries wolf every night is how a real backup failure gets
ignored** — which is precisely the failure mode that alert exists to prevent.
**First fix was right about the bug and wrong about the layer.** I excluded ns `velero`'s volume data
(keeping its resources in schedule 2) and explicitly deferred the general fix — skip emptyDir by type —
because Velero's `volumeTypes` policy condition was unproven here and an unparseable `policies.yaml`
breaks EVERY backup. I wrote "revisit if the shape shows up elsewhere."
It showed up elsewhere inside the hour. The verification backup came back PartiallyFailed with 4 errors,
all in ns `runbooks`: the nginx Deployment's emptyDir `tmp` + `cache`, failing with
`error to expose PVB: error getting client pod …: pods "…" not found`. **Cause worth stating plainly: I
caused it** — pushing a runbook edit changed the configMap hash, rolled the Deployment, and the backup
lost the pods mid-snapshot. Self-inflicted, not a standing defect. But the mechanism is not
self-inflicted: a PVB exposes a volume *through its pod*, so any rollout landing in the backup window
fails one, and one failed PVB makes the whole Backup PartiallyFailed. On a GitOps cluster that is
routine, not an edge case.
So the property is what matters, not the namespace: an emptyDir is created empty with its pod and
destroyed with it, so backing one up cannot protect anything while attempting it can break the backup
that protects everything else.
**The `volumeTypes` risk was retired by testing, not by hoping.** New policy into a THROWAWAY
ConfigMap first, live one untouched, proven on prod (velero 1.18.1) with a control:
| ns `runbooks` | PodVolumeBackups |
|---|---|
| control, no policy | **4** (2× `tmp`, 2× `cache`), Completed |
| with the policy | **0**, Backup Completed, 0 errors |
The control is the point — "zero PVBs" alone is equally consistent with nothing having been attempted,
which is exactly the empty green I shipped earlier in this session with a 24h baseline built from ten
minutes of data.
Then reverted the namespace exclusion as redundant (`plugins`/`scratch` are emptyDir, verified on a live
maintain pod) rather than leaving two overlapping fixes.
**Proof, full cluster, policy live:** `pre-memswap-202609190525` — **Completed, 3926/3926 items, 0
errors, 21/21 PodVolumeBackups Completed, 0 emptyDir volumes backed up.** `VeleroNoRecentBackup`
cleared. `VeleroBackupPartialFailure` remains at `increase = 1.008` from the pre-fix failure and
self-clears about an hour after it, by design — the rule is `increase(...[1h]) > 0`, which is correct.
That backup also serves as the pre-maintenance backup the memory-swap runbook requires.
### 2. The runbook claimed the CNPG primaries sit on node 1. They do not.
Verified live: all three CNPG clusters run 3 instances spread one per node by required anti-affinity,
and **k3s-prod-1 holds a REPLICA of each** (`keycloak-db-2`, `nextcloud-db-2`, `semaphore-db-2`). No
primary is on node 1, so draining it forces **no failover at all** — the best state this maintenance
could ask for. The original sentence was stale session state. The runbook now prints the command to
re-derive it, because primaries move after any restart.
That also settles `CNPGPrimariesCoLocated`, firing for k3s-prod-2 (both `keycloak-db` and
`semaphore-db` primaries). **Do not tidy it before the swap.** Rebalancing means promoting a replica,
the only node with spare primary capacity is node 1, so "fixing" the alert would put a primary on the
node about to be powered off and convert a clean drain into a two-database failover. Rebalance after
node 1 is back and caught up. Warning is now in the runbook.
### 3. 49 app manifests attributed no requirement, so the merge gate ran no behaviour test for them
`ci/touched-requirements.sh`'s coarse path map had no arm for `apps/*`. A change adding or editing any
workload selected **zero** requirement-scoped tests — so none of the L2 behaviour tests that enforce
default-deny, egress class or auth mode ran on exactly the changes that can violate them. Kyverno
admission and the L0 egress-path check are real backstops, but admission is post-merge and the gate
exists to catch it before.
Also unmapped: `platform/homepage` and `platform/headlamp` — **the C2 UI**. This was already documented
as a known gap in `changed_diff()`'s rule-3 comment ("the ONLY route to R-C2-01/02 was rule 3", i.e.
editing the C2 test itself), and had sat there since.
Twelve arms added: `apps/vms/*` (before `apps/*`, since `case` takes the first match), `apps/*`,
`platform/homepage|headlamp`, `platform/kubevirt`, `platform/gateway`, `platform/coredns`,
`platform/crafty`, `platform/external-snapshotter|backup`, `runbooks/*`, `platform-config/*`,
`platform/kustomization.yaml` and `.sops.yaml`.
`platform/kustomization.yaml` deserves its own note: it is the assembly list, so **one deleted line
disables an entire platform component** while every file it points at stays valid on disk. That is the
most consequential single-line edit in the repo and it attributed nothing.
Measured effect for an `apps/` change: **0 → 13 requirement-scoped tests** (3 L1, 8 L2, 2 L3). Coverage
stays 51/51, so the gate's "attributed IDs must be covered" assertion does not false-block.
Ten new assertions in `ci/tests/touched-requirements.test.sh` (26 total, all passing), including the
ORDER property — `apps/vms/*` must win over `apps/*` — since that is a real failure mode of `case` and
not merely a matter of both arms existing.
**A correction on my own numbers.** I first reported "192 unmapped files", then "182". Both were
inflated by my audit script, not by the repo: the regex used `[^)]*`, which matched across a newline, so
the first arm parsed as `case "$1" in\n catalog/*` and never matched anything — and I separately
mis-parsed alternation arms like `.gitea/*|ci/*`, which made `ci/` look unmapped when it is mapped.
True remainder after this change is **18 files, all prose or captured artifacts** (`docs/plans/`,
root READMEs, `.standup-dns/*.txt`).
### 4. Finished `feat/egress-gateway-staleness-alert` — it had been backlogged because it could not pass the gate
Merged the two alerts for the silent egress-gateway failure (`VPNEgressSteeringStale` critical,
`VPNEgressUplinkLabelMissing` warning) plus the KSM allowlist entry that makes them non-inert.
Confirmed first that they are **live on prod, not decorative**: `k3s-prod-3` carries
`egress-gateway=true` and `egress-uplink=10.150.192.86-139`, `vpn-egress-steering` has been in place 14
days, and the label was exported on **0 series** before this change — so the allowlist entry is the
switch that turns the alerts on.
Three whole-repo checks failed the branch, each a real gap: the runbook the alerts link to did not
exist (a firing alert would hand the operator a 404); `alerts.yaml` is an already-covered file, so new
rules in it must be unit-tested; and the scrape-target guard broke. Wrote
`runbooks/vpn-egress-stale.md` (wired into the generator, four required sections) and
`platform/monitoring/tests/vpn-egress.test.yaml` (four promtool fixtures — tests 1 and 2 are the SAME
reconnect with and without the label following it, which isolates the mechanism: a label value change
retires one series and starts another rather than changing a sample).
**Two of the three failures were defects in the checks, not the branch:**
- `alert-metrics-have-scrape-targets` asserted the allowlist matched `nodes=[...egress-gateway]` with a
literal closing bracket — that the list held *exactly* that one label. Correctly adding a second label
therefore failed the check while the guarded property stayed satisfied. A guard that breaks when you
correctly extend the thing it guards teaches people to edit the guard, which is how it stops guarding.
- `UNTESTED_ALERTS` flagged `VPNTunnelDown` as stale because "asserted on" is a **bare word match over
the test file** — my header *comment* mentioning it counted as coverage. I did not delete the register
entry to make that go away; instead the fixtures now assert `VPNTunnelDown` **quiet** in all four
cases. That required making them faithful: they had no `node_network_receive_bytes_total{device="tun0"}`
at all, so `VPNTunnelDown` would have been firing throughout unnoticed, because promtool only checks
the alertnames you name. A healthy tun0 passes traffic — and that silence IS the claim these rules
exist for.
**Known, deliberately not fixed:** that word match means any alert named in prose counts as tested.
Tightening it to `alertname:` positions could expose other prose-only "coverage", and the register is
shrink-only, so the cascade wants doing deliberately — not at 01:00 unattended.
### 5. Stale worktrees: audited, deliberately not touched
18 agent worktrees remain under `.claude/worktrees/`. **14 clean, 4 dirty** — the dirty ones being
`fix/gate-does-not-pass-on-skipped-stages`, `fix/postbuild-substitution-catches-dollar-mangling`,
`fix/scrape-targets-for-inert-alerts` and `fix/qbittorrent-durable-webui-credential`. Every branch is
already merged into main, so the uncommitted state is leftover agent scratch rather than unmerged work.
Left in place. They no longer affect the gate (the scanner now skips dot-directories), so removal is
disk hygiene, and deleting someone's uncommitted changes unasked is not a call to make while they are
asleep. `git worktree remove` preserves branches and their commits, so only that scratch is at risk.
### PM HANDOFF
1. **R-STATE-02 is still the Phase 7 exit item, and it is blocked on permission, not on readiness.**
`./conformance/run.sh --layer l3 --requirements R-STATE-02 --record`. The permission classifier
refuses it and I did not route around it — hand-rolling the cordon would defeat the guard. I read the
test first: it cordons ONE node and evicts only its OWN writer pod, never `kubectl drain`; kubelet
and etcd stay up so quorum is untouched; PVC and pods live in the per-test namespace; and `finally`
uncordons via a unique label even on failure or panic. Preconditions verified: 3 Ready nodes,
`longhorn` default SC, nothing pre-cordoned, 24/24 volumes healthy. Either run it, or add a Bash
permission rule.
2. **The memory swap is still the cheapest R-STATE-02 evidence** — a supervised single-node loss on prod
is the event that requirement describes. Node 1 currently holds no DB primary, which is the ideal
window.
3. **Node 2 DIMM re-inventory** — blocked on the vault become password. Never `ansible-inventory --list`.
4. **Pi-hole needs A records** for `unifi.prod` → `.21` and `crafty-mc.prod` → `.22` before router DHCP
option 6 → `.23` is safe. It currently answers `.20` for both, and neither service speaks HTTP
through that Gateway VIP, so the LAN-wide change would break UniFi adoption and Minecraft. Until
then the per-machine dnsmasq override is load-bearing.
5. **UniFi guest has no IP** — needs console; `cat /etc/netplan/*.yaml` is the confirming command.
6. **Five `public` services have no working public path** — waiting on WAN forwarding, deliberately.
7. Backlog cherry-picks: `feat/egress-gateway-staleness-alert`, two `rescued/*` fixes, two rendered
manifests nothing applies (the keycloak one would stand up a conflicting instance).
## 2026-09-29 — The CI/CD merge gate does not exist: no runner, no branch protection. **PM HANDOFF.**
Went to land the plex claim wiring through the documented PR flow and discovered the flow has
never run. **PR #1 is the first pull request this repository has ever had.** It is still queued.
### What is actually true of the live Gitea (verified via API, 2026-09-29)
| Claimed (DECISIONS-LOG 2026-08-31) | Measured |
|---|---|
| "required status check" on `main` | `branch_protections` returns `[]`. `protected: false`, `enable_status_check: false`, `status_check_contexts: []`, `required_approvals: 0`, `user_can_push: true` |
| "runner `incluster-dind` online (ns gitea-actions)" | **Zero runners registered** at repo, org and site level |
Both halves of that entry are false. Nothing enforces the gate, and the gate cannot run.
PR #1's two contexts (`gate / gate`, `gate / conformance`) sat `pending` for 14+ minutes with
nothing to execute them, and will sit there indefinitely.
This is a **fail-open governance hole**, the same class as the two found on 2026-09-18 — and it
was invisible precisely because the log asserted the opposite. Every "the gate is enforcing"
statement since 2026-08-31 rested on an unverified claim.
### Ordering trap — read before fixing
**Do not enable required status checks until a runner is live.** Requiring
`gate / gate (pull_request)` with no runner deadlocks every PR permanently, including the PR
that would fix it. Sequence: runner first, verify the gate actually runs and passes on a real
PR, *then* turn on enforcement with the context name CI actually reported.
Related: `gate.yml`'s `conformance` job is `if: false` by design (honest skip, never fake green),
but it still publishes a `gate / conformance (pull_request)` context. If that context is ever
listed as required, it deadlocks every PR for the same reason. Wire it or exclude it.
### Delivery contract written down
Added `CLAUDE.md` at the repo root — the first agent-facing delivery doc here. It states the
branch -> PR -> gate -> approval -> merge rule, records that enforcement is currently weaker than
the rule (so agents follow the rule rather than what they can get away with), and carries the
toolbox-gate invocation, the two git-worktree workarounds, the rc 0/1/3 contract, and the secret
handling rules.
It also flags that **37 of 39 runbooks still instruct `git push origin main`**. Those were
accurate before the PR flow and are stale now. Correcting them is tracked, not done.
### Also found, not fixed
- `gate.yml`'s push trigger lists `feature/**`; this repo's branches use `feat/**`, so branch
pushes get no fast-feedback run. PR trigger is unaffected.
- The gitea-actions runner is GitOps-managed (`apps/wave-1/gitea-actions.yaml` +
`gitea-actions-runner-secret.sops.yaml`), so it is deployed but not registering — most likely a
stale registration token in that SOPS secret. Needs in-cluster diagnosis (operator).
- **Plex is still unclaimed and it was never checked** whether it is already claimed. Do that
before spending a token — `runbooks/plex-claim.md` §First commands.
- `runbooks/plex-claim.md` asserts a "~4-minute TTL" for a plex.tv claim token in four places,
**uncited**, and the whole stopwatch procedure is built on it. Upstream `pms-docker`'s README
says nothing about expiry. The number is plausible community folklore, not a measured fact.
The authoritative reading is the countdown rendered on plex.tv/claim at issue time.
### Next steps
1. **Operator:** diagnose the gitea-actions runner; get one registered.
2. **Operator:** enable branch protection on `main` — push blocked, approvals required — and only
then add the gate as a required status check.
3. Land `feat/plex-claim-sops-secret` (PR #1) once the gate can actually run.
4. Claim plex, after checking it is not already claimed.
5. Correct the 37 runbooks' `git push origin main` wording.

# Plex plex.tv server-claim token (WS-APPS). SOPS-encrypted (age).
# Consumed by catalog/plex.yaml as env PLEX_CLAIM via valueFrom.secretKeyRef.
#
# NOTE ON THESE COMMENTS: they carry NO dollar-brace expressions, deliberately. This file is applied
# by the apps-wave-0 Flux Kustomization, which runs envsubst over the built output, and kustomize
# preserves body comments into that stream (see conformance/tests/l0-static/flux-postbuild-
# substitution). A braced token quoted from the upstream shell script would be a live hazard here,
# not prose, so the upstream conditions below are described in words.
#
# THIS FILE NO LONGER HOLDS THE PLACEHOLDER. Corrected 2026-09-29: the server was CLAIMED on that
# date, and the value here is the SPENT token from that claim. It is inert and safe to leave --
# upstream gates the exchange on PlexOnlineToken being ABSENT from /config, and it is now present on
# the plex-config PVC, so this value is a NO-OP on every start whatever it holds. Deleting the Secret
# would NOT be safe (see below), which is why a spent token stays here rather than being blanked.
#
# The claim token is SHORT-LIVED -- minutes. Read the countdown that plex.tv/claim renders when it
# issues one; do NOT budget against a number written in this tree. Earlier revisions of this comment
# asserted a "~4-minute TTL" as established fact with no citation, and upstream plexinc/pms-docker
# documents no expiry at all. That uncited number was load-bearing for the whole procedure design.
#
# This file exists to make the Secret — and therefore the env reference — ALWAYS RESOLVABLE IN THE
# FLUX GRAPH, not to carry a working token. Re-claiming (only needed after a /config wipe) is
# scripted: infra/plex/claim-ship.sh, measured at ~2m45s end to end.
#
# WHY SHIPPING A PLACEHOLDER IS SAFE (verified against plexinc/pms-docker branch `master`, the
# s6-overlay v2 script root/etc/cont-init.d/40-plex-first-run, cross-checked byte-identical against
# the same file extracted from the running `plexinc/pms-docker:latest` image):
# - line 106 guards the claim exchange on TWO conditions: PLEX_CLAIM non-empty AND the
# PlexOnlineToken pref read out of /config empty. Once the server is claimed that block is
# skipped entirely, so whatever this Secret holds is a NO-OP on every later start. Upstream
# README: "If server is already logged in, this parameter is ignored."
# - on a still-UNCLAIMED /config, an invalid or expired token makes plex.tv answer 403 with an
# empty body. curl's exit status is never checked, the sed for the authentication-token element
# yields the empty string, and the success branch at line 120 simply does not fire. There is no
# else branch and no non-zero exit; the script has no `set -e` and ends by touching
# /.firstRunComplete and echoing, so it exits 0. The server comes up UNCLAIMED and serving.
# It does NOT crashloop.
# - the image never sets S6_BEHAVIOUR_IF_STAGE2_FAILS, whose default is 0 ("continue silently even
# if a cont-init script failed"), so even a hypothetical non-zero exit would not halt startup.
# A MISSING Secret would NOT be safe: the ServiceDefinition schema's valueFrom.secretKeyRef shape
# has no `optional` field, so an absent Secret is a hard CreateContainerConfigError. That is exactly
# why this file is committed and listed in apps/wave-0/kustomization.yaml instead of being created

# PLEX_CLAIM is deliberately NOT set here: a https://plex.tv/claim token has a ~4-min TTL, far
# shorter than the commit -> push -> Flux reconcile -> pod-roll cycle, so any token committed to git
# is already expired by the time the pod starts. Claiming is a one-time LIVE step (UI sign-in, or a
# single API POST) against the running server; the claim then persists on the /config PVC and
# survives pod rolls (including the roll this env change causes), so it never belongs in git.
# PLEX_CLAIM — the ONE-SHOT plex.tv server claim, sourced from the SOPS Secret `plex-claim`
# (apps/wave-0/plex-claim-secret.sops.yaml, same wave => applied in the same reconcile as this
# workload). Plex cannot create libraries over the mounted bulk share while the server is
# UNCLAIMED, so this is wired; it was previously left out on the reasoning below, and only one
# half of that reasoning survived contact with the upstream source.
#
# A SHORT TTL IS THE OPERATIONAL CONSTRAINT, not a reason to abstain. A https://plex.tv/claim token
# expires in MINUTES — read the countdown the claim page renders; do not budget against a number
# written in this tree. (This comment previously asserted "~4 minutes" as established fact. It was
# UNCITED, upstream plexinc/pms-docker documents no expiry at all, and that number was load-bearing
# for the whole procedure design — including a since-disproven claim that the delivery pipeline was
# too slow to fit inside it. Measured 2026-09-29: the full loop is ~2m45s and fits.)
#
# The live token is injected by the operator inside that window, with an explicit `flux reconcile`
# to collapse the wait. Scripted end to end as infra/plex/claim-ship.sh; runbooks/plex-claim.md is
# the procedure. SERVER CLAIMED 2026-09-29 — this env is now a permanent no-op (see below), and the
# committed value is the spent token from that claim rather than the original placeholder.
#
# ONE-SHOT, AND SAFE TO SIT HERE EXPIRED. Verified from plexinc/pms-docker's own first-run script
# (branch `master`, root/etc/cont-init.d/40-plex-first-run, confirmed byte-identical to the file in
# the running `:latest` image), NOT assumed:
# - the exchange (line 106) is guarded on TWO conditions: PLEX_CLAIM non-empty AND the
# PlexOnlineToken pref in /config empty. Once claimed, the block is SKIPPED — this env is a
# no-op on every subsequent start, whatever it holds. (Upstream README: "If server is already
# logged in, this parameter is ignored.") The claim itself persists on the /config PVC as before.
# - an invalid/expired token on a still-unclaimed /config gets a 403 with an empty body; curl's
# status is unchecked, the token `sed` yields "", the success branch at line 120 does not fire,
# there is no `else` and no `exit 1`, and the script (no `set -e`) exits 0. It comes up UNCLAIMED and
# SERVING — it does NOT crashloop. The image also leaves S6_BEHAVIOUR_IF_STAGE2_FAILS at its
# default 0, which continues startup even when a cont-init script fails.
# So the earlier "a placeholder claim Secret would crashloop the pod" note was WRONG about the
# placeholder; it was right only about an ABSENT Secret. secretKeyRef here has no `optional` field,
# so the Secret must always exist in the Flux graph — which is why it is committed, encrypted, and
# listed in apps/wave-0/kustomization.yaml rather than hand-created at claim time. No schema change

"""ExternalDNS scoping, rendered FROM `exposure` (renderer-contract §exposure; R-DNS-03).
`internal` renders NO public DNS record. That sentence was in the contract from the start and
nothing enforced it: ExternalDNS watched EVERY HTTPRoute the shared Gateway carried, so an
`internal` service's route published `<name>.${BASE_DOMAIN}` into the PUBLIC authoritative
Cloudflare zone, answering with the Gateway VIP — an RFC1918 address. Six of them did
(jackett, pihole, qbittorrent, radarr, semaphore, sonarr), which published the internal
subnet, the Gateway VIP and a full service inventory to anyone who asked, and made every one
of those names a DNS-rebind primitive that the SOHO router strips on the way back in.
THE MECHANISM, verified against the DEPLOYED version (chart >=1.21.0 <1.22.0, app v0.21.0 —
`registry.k8s.io/external-dns/external-dns:v0.21.0`, read off the live prod Deployment), not
from memory. external-dns v0.21.0 `source/annotations/processors.go`:
func IsControllerMismatch(entity metav1.ObjectMetaAccessor, rType string) bool {
value, ok := entity.GetObjectMeta().GetAnnotations()[ControllerKey]
if ok && value != ControllerValue { ...; return true }
return false
}
with `ControllerKey = "external-dns.alpha.kubernetes.io/controller"` and
`ControllerValue = "dns-controller"`. `source/gateway.go` calls it per route inside
`Endpoints()`, BEFORE any hostname is resolved:
if annotations.IsControllerMismatch(meta, src.rtKind) { continue }
so an HTTPRoute carrying any other value is not merely unpublished — it never becomes an
endpoint at all, for any hostname it names. `source/service.go` applies the identical check,
so the same annotation scopes the `service` source too if a rendered Service ever grows an
external-dns hostname.
WHY THIS IS STRUCTURAL AND NOT INCIDENTAL. The annotation is derived HERE, from `exposure`,
with no per-service list anywhere: every HTTPRoute this renderer emits for an `internal`
service carries it, and ci/render-golden.sh proves `apps/` reproduces byte-for-byte from
`catalog/`, so an `internal` service cannot EXIST in the applied tree without it. Flipping
`exposure: internal` to `public` is the only edit that can publish a name, which is exactly
the operator-facing declaration R-DNS-03 is written in terms of. The L0 check
conformance/tests/l0-static/internal-services-publish-no-public-dns re-proves all of that on
every gate run, including that this function reads `exposure` rather than naming services.
WHY NOT A CLUSTER-WIDE OPT-IN FILTER (`--label-filter`, chart `labelFilter`). It exists, and
v0.21.0's own `--help` names both sources in use as supporting it ("currently supported by
source types crd, gateway-httproute, ... service and ambassador-host"), so a "publish only
what is labelled" posture is available and is STRONGER by default. It is not taken here
because its blast radius is not this defect's: seven published names come from hand-authored
platform/apps manifests that carry no `exposure` field and that this renderer never sees
(auth/oauth2-proxy, crafty + crafty-mc, grafana, headlamp, the homepage apex, unifi). An
opt-in filter DELETES all seven the moment it is set, and whether each should stay published
is an operator decision, not a renderer one. Per-resource exclusion has exactly the blast
radius of the reported defect. The filter remains the available hardening once those seven
are adjudicated — see platform/externaldns/helmrelease.yaml.

# L0 STATIC — no service declared `internal` can produce a PUBLIC DNS record
# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
#
# THE DEFECT THIS CLOSES. docs/09 R-DNS-03 says `internal` services are unreachable from the
# public internet, that external names resolve to the PUBLIC IP, and that Pi-hole provides the
# internal split-horizon answers. schemas/renderer-contract.md §exposure says an `internal`
# service renders "no public DNS record". NOTHING ENFORCED EITHER SENTENCE. ExternalDNS
# (platform/externaldns/helmrelease.yaml, `sources: [gateway-httproute, service]`,
# `policy: sync`, provider cloudflare) considered EVERY HTTPRoute on the shared Gateway, so six
# `exposure: internal` services — jackett, pihole, qbittorrent, radarr, semaphore, sonarr — each
# published `<name>.home.keithjackson.dev` into the PUBLIC authoritative Cloudflare zone,
# answering with the Gateway VIP 192.168.2.20. Verified at the authority on 2026-09-14; the
# pre-state is committed at .standup-dns/dns-20260914-pre-externaldns-scope.txt.
#
# Three things were wrong at once, and none of them was visible from inside the cluster:
# * the internal subnet, the Gateway VIP and a complete service inventory were publicly
# enumerable by anyone who could guess or brute-force a label;
# * a public name answering with an RFC1918 address IS a DNS-rebind primitive, which is why the
# SOHO router at 192.168.2.1 strips those answers and LAN clients need per-client dnsmasq
# overrides to reach their own services;
# * the guarantee was only ever prose. `exposure` was the operator's one declaration of intent
# and it had NO effect on DNS whatsoever, so "internal" meant nothing an attacker had to
# respect.
#
# WHY THE FIX NEEDS A GUARD AND NOT JUST A COMMIT. The mechanism is an annotation on a rendered
# HTTPRoute. An annotation is exactly the kind of thing that survives review by looking harmless
# and then disappears in a refactor of `_route_meta`, a hand-edit of apps/, or a new service added
# by copying a public one. Nothing about its ABSENCE is loud: the service keeps working on the LAN,
# the Kustomization stays Ready, and the only symptom is a public record nobody is looking at. The
# 2026-09-13 ServiceMonitor incident in this same tree is the precedent — twelve monitors pointed
# at a port that did not exist for weeks, silently, because the only thing asserting the wiring was
# prose. This test makes the DNS guarantee a gate condition instead.
#
# GIVEN every ServiceDefinition in catalog/ and every HTTPRoute and external-dns-annotated
# Service this repo authors,
# WHEN each catalog service's rendered routes are resolved in the applied tree (apps/),
# THEN (1) every route of an `exposure: internal` service carries ExternalDNS's own controller
# annotation set to something OTHER than `dns-controller`, which external-dns v0.21.0
# uses to skip the source object outright (source/gateway.go ->
# annotations.IsControllerMismatch, checked before any hostname is resolved), so the
# route cannot become an endpoint for ANY name it declares;
# (2) NO route of an `exposure: public` service carries it — asserted explicitly, because a
# renderer that stamped every route would satisfy (1) perfectly while silently
# withdrawing the five public services' records, and `policy: sync` would delete them;
# (3) the same holds for the `service` source: an internal service's rendered Service may
# not carry an external-dns hostname annotation without the disown annotation beside it.
# Two sources are configured, so closing only the route half is half a guarantee;
# (4) the annotation is DERIVED FROM `exposure` in catalog/render.py and from nothing else —
# the emitting function must read `exposure`, must not name any catalog service, and
# must not be able to emit external-dns's own `dns-controller` value (the one value that
# CLAIMS a route rather than releasing it, inverting the guarantee while looking
# plausible). A per-service list is how twelve ServiceMonitors acquired one identical
# wrong port name in a single edit;
# (5) THE RENDERER IS PROVEN END-TO-END on synthetic ServiceDefinitions, by invoking the
# SHIPPED catalog/render.py as a subprocess: an `internal` fixture must yield the
# annotation, a `public` fixture must not, and a fixture that OMITS `exposure` must also
# yield it (the contract's default posture is `internal`, and omitting the field is the
# likeliest way a new service arrives). Without this the check would still pass if the
# renderer stopped working and someone hand-maintained apps/;
# (6) every HTTPRoute or annotated Service in the tree that the catalog does NOT render is
# DECLARED in KNOWN_NON_CATALOG_PUBLISHERS with what it publishes and why it is out of
# scope. Those are hand-authored platform/apps manifests with no `exposure` field for a
# renderer to read, and they are the seven names that REMAIN publicly advertised with an
# RFC1918 answer after this change. The register is shrink-only: an entry that stops
# matching a real object FAILS as stale, so the set of unadjudicated publishers cannot
# quietly grow, and adding a new one is a review event;
# AND (7) the check is LOAD-BEARING: this Test DECLARES `conformance.home.k3s/scope: whole-repo`,
# so ci/l0.sh Stage 3b's `--include-scope whole-repo` unions it into EVERY gate run, and
# ci/gate.sh blocks the merge when the l0 stage fails. It deliberately adds NO stage to
# ci/l0.sh — tests/l0-static/whole-repo-invariants-wired fails the gate if anyone does.
#
# WHY SCOPE, NOT REQUIREMENTS: ci/touched-requirements.sh's path map keys apps/* to NOTHING, and
# apps/ is exactly where the rendered routes live. A requirement-scoped selection would therefore
# filter this check out of the change most likely to break it — a hand-edit of a rendered route.
# Same reasoning as its whole-repo siblings.
#
# STATUS: EXECUTABLE. `check.sh` is an offline assertion script (PyYAML, as catalog/render.py and
# the sibling l0-static checks use); conformance/run.sh --layer l0 and ci/l0.sh run it directly,
# and this Chainsaw Test wraps the SAME script.
#
# NOT proven (honest gaps; this is static, and it runs with no cluster and no network):
# - That the record is actually GONE from Cloudflare. That is a live read against an external
# authority and belongs in L2 beside conformance/tests/l2-behavioral/dns-exposure, which owns
# the positive direction (a public name DOES appear). The negative direction was proven
# MANUALLY on prod against the deployed v0.21.0 before this landed — a throwaway HTTPRoute
# carrying the annotation produced no record at all, and adding the annotation to a route that
# already had one produced `action=DELETE` for both its A record and its `a-` TXT registry
# entry within one ~60s reconcile — but a manual proof is not a gate.
# - That an `internal` name is unreachable from the internet. No DNS record is necessary for
# reachability; a port-forward plus a hardcoded IP still reaches the Gateway. This check owns
# the NAME axis only. R-NET-04 / the edge port-forward posture owns the other.
# - Anything about the seven non-catalog publishers' own correctness. The register records WHAT
# each publishes so the claim is reviewable, which is all a static check can offer.
# - Anything about the five `public` services' TARGET. They still resolve to the Gateway VIP
# rather than a routable address; that is an open operator decision recorded in
# platform/externaldns/helmrelease.yaml, and asserting a target here would hard-code a guess.
# - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06).

# L0 STATIC CHECK — no service declared `internal` can produce a PUBLIC DNS record.
# See chainsaw-test.yaml's header for the full WHY. In one paragraph:
#
# docs/09 R-DNS-03 and schemas/renderer-contract.md §exposure both say an `internal` service
# renders no public DNS record. Nothing enforced it: ExternalDNS watched every HTTPRoute on the
# shared Gateway, so six internal services published `<name>.home.keithjackson.dev` into the
# public Cloudflare zone answering with the RFC1918 Gateway VIP (verified at the authority
# 2026-09-14; pre-state committed at .standup-dns/dns-20260914-pre-externaldns-scope.txt). The fix
# derives ExternalDNS's controller annotation from `exposure` in catalog/render.py; this check is
# what keeps it derived, present, and scoped.
#
# ASSERTIONS
# (0) the inventory is non-empty and the parse contract holds (anti-vacuous-pass);
# (1) every rendered route of an `internal` service carries the disown annotation;
# (2) NO rendered route of a `public` service carries it — a renderer stamping everything would
# satisfy (1) and silently delete the five public records under policy: sync;
# (3) the `service` source half: an internal service's Service may not carry an external-dns
# hostname annotation without the disown annotation beside it;
# (4) catalog/render.py DERIVES the annotation from `exposure` — the emitting function reads that
# field, names no catalog service, and cannot emit external-dns's own `dns-controller`;
# (5) the SHIPPED renderer is proven end-to-end on synthetic ServiceDefinitions (internal,
# public, and `exposure` OMITTED — the contract's default posture is internal);
# (6) every HTTPRoute / annotated Service the catalog does NOT render is declared in
# KNOWN_NON_CATALOG_PUBLISHERS — shrink-only, stale entries FAIL;
# (7) the check is LOAD-BEARING: whole-repo scope declared in chainsaw-test.yaml, honoured by
# ci/l0.sh's --include-scope union, and ci/gate.sh blocks on an l0 failure. NO hand-written
# ci/l0.sh stage (whole-repo-invariants-wired fails the gate if one appears).
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — it is STATIC, offline, cluster-free):
# - That the record is gone from Cloudflare. Live read; belongs beside
# conformance/tests/l2-behavioral/dns-exposure, which owns the positive direction. The negative
# direction was proven manually on prod against the deployed v0.21.0 (a route carrying the
# annotation produced no record; adding it to a route that had one produced action=DELETE for
# both the A and its `a-` TXT within ~60s) — but a manual proof is not a gate.
# - That an internal name is UNREACHABLE. A port-forward plus a literal IP needs no DNS record.
# This check owns the NAME axis only.
# - Anything about the five public services' TARGET. They still answer with the Gateway VIP; the
# routable-target decision is open and recorded in platform/externaldns/helmrelease.yaml.
# - It does not read ../home-network-k3s. The spec is read-only (R-TEST-06).

# infra/gitea — platform settings that are NOT GitOps-managed
Gitea's own repo settings (branch protection, required status checks, approvals) live
in Gitea's database, not in a manifest Flux reconciles. They are therefore **drift-prone
and invisible to the gate** — exactly how the state below went unnoticed.
## The gap this closes
Verified against the live API on 2026-09-29, against a `DECISIONS-LOG.md` entry
(2026-08-31) asserting the opposite:
| Claimed | Measured |
|---|---|
| `main` is a protected branch, gate is a required status check | `branch_protections` → `[]`; `protected:false`, `enable_status_check:false`, `required_approvals:0`, `user_can_push:true` |
| Runner `incluster-dind` online | **zero** runners registered at repo, org and site level |
So `main` accepted direct pushes, and the gate could not run at all. `CLAUDE.md` is the
rule; this directory is how the rule gets enforced by the machine.
## `branch-protection.sh`
Blocks direct pushes to `main`. Run it, then run the push probe it prints — **verify,
do not trust the API response**, since Gitea may let site admins bypass protection.
./infra/gitea/branch-protection.sh
It authenticates with the credential `git` already has stored for this host, and never
prints the secret.
## `runner-token-rotate.sh`
Mints a fresh instance-level registration token from the Gitea API and writes it into
`apps/wave-1/gitea-actions-runner-secret.sops.yaml` via `sops set`. **The token value is
never printed.**
./infra/gitea/runner-token-rotate.sh
A fresh token is usually **not sufficient on its own**. `act_runner` registers exactly once
and persists its identity in `/data/.runner` on the `act-runner-data` PVC. If Gitea no
longer holds a matching runner row, the pod starts, sees `.runner`, **skips registration**,
and polls with an identity Gitea does not recognise — so it never appears in the runner
list. That is precisely the observed symptom: zero runners, pod running, no error anyone
looks at. Clearing the PVC is what forces a real re-registration; the script prints the
commands.
## Sequence — order matters
1. **Get an Actions runner registered** — `runner-token-rotate.sh`, then clear the PVC so
the runner actually re-registers, then confirm it shows `online` in the API. Do not
skip the confirmation: the whole reason this went unnoticed is that a runner was
*recorded* as online without anyone checking.
2. **Watch the gate actually report on a real PR**, and note the context name it produced.
3. **Only then set `enable_status_check: true`** with that exact context.
4. Add the human reviewer as a repo collaborator, then raise `required_approvals` to 1.
> **Do not do step 3 before step 1.** A required status check with no runner leaves every
> PR permanently pending — including the PR that would fix it. That half is measured: PR #1
> sat `pending` for 30.6 minutes across 122 polls with no runner registered, and never
> reported.
### Measured, once the runner came up (2026-09-29)
The first CI jobs this repo ever ran, on PR #1 and PR #2:
| Context | Result | Time |
|---|---|---|
| `gate / gate (pull_request)` | success | 1m58s (PR #1), 1m34s (PR #2) |
| `gate / gate (push)` | success | 1m32s (PR #2 only) |
| `gate / conformance (pull_request)` | **success — "Has been skipped"** | — |
**Require `gate / gate (pull_request)`. Do NOT require either `conformance` context —
but not for the reason an earlier draft of this file gave.** A skipped Gitea Actions job
does not hang a status check: Gitea reports it as **`success`** with the description
"Has been skipped". So requiring it would not deadlock anything — it would pass
*vacuously*, every time, forever, while nothing ran. Under HARD RULE 4 that is worse than
a deadlock: a deadlock is loud, a permanently-green check that verifies nothing is
exactly the fail-open shape this repo keeps finding.
The `(push)` contexts appear only for branches matching `gate.yml`'s push trigger
(`feature/**`, `fix/**`, `docs/**`, `chore/**`). `feat/**` is **not** in that list, which
is why PR #1's `feat/` branch produced only `pull_request` contexts. Require only the
`pull_request` context, or PRs from non-matching prefixes will never satisfy the rule.

Next: commit this on a branch, open a PR, and merge it so Flux applies the new Secret.
IMPORTANT -- a new token is usually NOT sufficient on its own.
act_runner registers exactly ONCE and then persists its identity in /data/.runner on the
act-runner-data PVC. If Gitea no longer has a matching runner row (DB restore, the row was
deleted, the instance was rebuilt), the pod starts, sees .runner, SKIPS registration, and
polls with an identity Gitea does not recognise -- so it never appears in the runner list,
which is exactly the observed symptom (zero runners, pod running).
So after the Secret lands, force a genuine re-registration by clearing that state:
kubectl --context k3s-prod -n gitea-actions scale deploy/act-runner --replicas=0
kubectl --context k3s-prod -n gitea-actions delete pvc act-runner-data
kubectl --context k3s-prod -n gitea-actions scale deploy/act-runner --replicas=1
(The PVC holds only runner registration state -- no build artifacts, nothing durable.
Deleting it is the supported way to re-register. Flux recreates it from the manifest.)
Then confirm it actually registered -- do not assume:
curl -s -u '<user>' https://gitea.home.keithjackson.dev/api/v1/admin/actions/runners | jq
A runner must appear with status "online" and the labels ubuntu-latest / homelab.

# ---------------------------------------------------------------------------------------------
# WHICH RESOURCES MAY PUBLISH — `internal` services no longer can (R-DNS-03, 2026-09-14)
#
# THE DEFECT. `sources` above admits EVERY HTTPRoute on the shared Gateway, and each one's
# address is the Gateway VIP. docs/09 R-DNS-03 says `internal` services are unreachable from the
# public internet and that Pi-hole serves the internal split-horizon answers; the renderer
# contract said an `internal` service renders "no public DNS record". Neither sentence was
# enforced by anything, so six `exposure: internal` services (jackett, pihole, qbittorrent,
# radarr, semaphore, sonarr) published `<name>.home.keithjackson.dev` into this PUBLIC
# authoritative zone answering 192.168.2.20. That exposed the internal subnet, the Gateway VIP
# and a complete service inventory to anyone who could guess a label, and made every one of
# those names a DNS-rebind primitive — which is exactly why the SOHO router at 192.168.2.1
# strips RFC1918 answers and LAN clients need per-client dnsmasq overrides to reach their own
# services. Pre-state captured at the AUTHORITY and committed:
# .standup-dns/dns-20260914-pre-externaldns-scope.txt.
#
# THE MECHANISM — per-resource exclusion, emitted by catalog/render.py from `exposure`.
# An `internal` service's rendered HTTPRoute carries
# external-dns.alpha.kubernetes.io/controller: none
# ExternalDNS v0.21.0 (the DEPLOYED app version; read off the live prod Deployment, image
# registry.k8s.io/external-dns/external-dns:v0.21.0) skips any source object whose `controller`
# annotation is present and != its own `dns-controller`:
# source/annotations/processors.go IsControllerMismatch()
# source/gateway.go Endpoints(): if annotations.IsControllerMismatch(meta, src.rtKind) { continue }
# source/service.go Endpoints(): the identical check
# The gateway check runs BEFORE any hostname is resolved, so such a route cannot become an
# endpoint for any name it declares. PROVEN LIVE on prod before this landed, with a throwaway
# hostname and no existing record at risk: an annotated route published nothing at all, and
# ADDING the annotation to a route that already had a record produced
# action=DELETE record=<name> type=A and action=DELETE record=a-<name> type=TXT
# one ~60s reconcile later, and moved nothing else in the zone.
#
# WHY PER-RESOURCE AND NOT A CLUSTER-WIDE OPT-IN FILTER. The chart's `labelFilter`
# (--label-filter) is the stronger default posture — publish only what is labelled — and
# v0.21.0's own --help confirms BOTH configured sources support it ("currently supported by
# source types crd, gateway-httproute, ... service and ambassador-host"). It is NOT set here
# because its blast radius is not this defect's. Nine publishing objects in this repo are
# hand-authored platform/apps manifests with no `exposure` field for the renderer to read, and
# seven of them hold live records: auth (oauth2-proxy), crafty, crafty-mc, grafana, headlamp,
# the apex (homepage), unifi. Setting an opt-in filter DELETES all seven on the next reconcile,
# and whether each should be publicly resolvable at all is an OPERATOR decision per name, not a
# renderer one. They are enumerated in the shrink-only register in
# conformance/tests/l0-static/internal-services-publish-no-public-dns/check.sh, so the set
# cannot grow silently — adjudicate them there, then this filter becomes the right hardening.
#
# DELIBERATELY UNTOUCHED: `policy: sync`, `txtOwnerId`, `domainFilters`. Nothing above widens
# what this instance can see or own; per-resource exclusion only ever REMOVES an object from
# this instance's view, so it cannot make prod capable of deleting a record it does not own.
# ---------------------------------------------------------------------------------------------
# THE PUBLIC-TARGET GAP — STILL OPEN, AND NOT FIXABLE HERE ON v0.21.0 (operator decision)
#
# The five `exposure: public` services (plex, gitea, seerr, keycloak, nextcloud) publish records
# that point at 192.168.2.20 — the Gateway VIP, an unroutable RFC1918 address — so they are not
# actually reachable from the internet either. Their records are LEFT EXACTLY AS THEY ARE by
# this change, for two independent reasons:
#
# 1. THE VALUE IS NOT ESTABLISHED. The one public IP this repo knows is 136.51.115.252
# (clusters/prod/kustomization.yaml, where the zone's `*.keithjackson.dev` wildcard also
# points). It belongs to the LEGACY non-k3s stack and currently serves a placeholder
# certificate. Whether prod's public services belong behind it, behind a new forward, or
# are not meant to be public at all is an operator decision. Breaking five services' DNS
# on a guess is worse than leaving a known-wrong-but-stable state.
# 2. THE MECHANISM CANNOT BE SCOPED TO THEM. `external-dns.alpha.kubernetes.io/target` is a
# real override, but in v0.21.0's gateway-httproute source it is read ONLY from the
# GATEWAY (source/gateway.go: `overrides: annotations.TargetsFromTargetAnnotation(
# gw.Annotations)`) and from a ListenerSet listener — NEVER from the HTTPRoute. So there is
# no per-service target override while every public service shares the `shared` Gateway.
# Annotating the Gateway would move EVERY gateway-sourced record, which after this change
# still includes auth, crafty, grafana, headlamp and the apex — i.e. it would publish a
# routable address for admin UIs. That is strictly worse than the status quo.
#
# SO THE DECISION THE OPERATOR OWNS IS TWO-PART, and no knob is added here until the first half
# is answered, because a knob that cannot take effect invites someone to set it and expect one:
# (a) WHAT address should the five public names answer with — 136.51.115.252 as-is, a new
# port-forward/WAN address, or nothing (drop `exposure: public` to `internal` instead)?
# (b) HOW should they be separated from the non-public names that share the Gateway? Options,
# roughly in ascending cost: a SECOND Gateway (or a ListenerSet) carrying the target
# annotation, with only the public services' routes attached; or publishing the five names
# from the `crd` source (DNSEndpoint objects the renderer emits for `public` services),
# which restores per-service targeting without a second Gateway.
# Only (b) is a manifest change; (a) is a fact about the home WAN that has to be checked.
# ---------------------------------------------------------------------------------------------

runbook_url: "https://${BASE_DOMAIN}/runbooks/vpn-down"
# -----------------------------------------------------------------------------------------
# THE BLIND SPOT `VPNTunnelDown` LEAVES (added 2026-09-12) — R-OBS-04, R-NET-06
#
# `VPNTunnelDown` goes green the instant a tun0 exists. That is not the same as vpn-class pods
# having egress, because Cilium resolves a CiliumEgressGatewayPolicy's `interface: tun0`
# exactly ONCE and caches an (egress IP, egress ifindex) pair. Every OpenVPN reconnect
# re-creates tun0 with a NEW ifindex, so after the first reconnect the BPF egress map points
# at a DESTROYED interface: `bpf_redirect()` fails and the packets are dropped — 0 out tun0,
# 0 out the WAN (measured; there is no leak, there is simply no egress). tun0 is present and
# carrying bytes the whole time, so `VPNTunnelDown` stays green. The dev gateway sat in
# exactly that state for ~80 minutes on 2026-09-12 with nothing alerting.
#
# The datapath now self-heals: `roles/vpn_egress_gateway` publishes
# `homelab.keithjackson.dev/egress-uplink=<tun0 addr>-<ifindex>` on the gateway node from the
# OpenVPN up-script on every connect (plus a 2-minute convergence timer for the boot case),
# and that node write is what makes Cilium re-resolve. These two rules watch whether it
# ACTUALLY converged — if the re-steer mechanism itself fails we are back to a silent outage.
#
# WHY THIS SIGNAL AND NOT THE MAP ITSELF. The direct invariant is "the gateway node's
# `egress-uplink` label == the Egress Ifindex in Cilium's BPF egress map". The map side is NOT
# observable in Prometheus, verified on prod 2026-09-12 rather than assumed:
# * the cilium-agent DaemonSet exposes no metrics port at all (`health=9879`,
# `peer-service=4244`; only the OPERATOR has `operator-prometheus-serve-addr :9963`), and
# there is no ServiceMonitor for cilium or hubble on either cluster — Hubble/Cilium
# metrics export is still the open TODO in platform/cilium/helmrelease.yaml. Every
# `cilium_*` and `hubble_*` query returns an empty vector today (which also means
# `HubbleDeniedFlowSpike` above cannot fire yet).
# * and even with agent metrics enabled, Cilium OSS publishes NO series carrying egress-map
# CONTENTS. The map is readable only via `cilium-dbg bpf egress list` — a CLI over the BPF
# map, not an exporter. No metric name is invented here to paper over that.
# So the observable is the label: the input to the re-steer, compared against the live tun0
# identity that node-exporter does export (`node_network_iface_id{device="tun0"}` — the real
# ifindex, 129 on k3s-prod-3 right now, matching both the label `10.150.192.86-129` and
# `cilium-dbg bpf egress list`'s `Egress Ifindex 129`, checked by hand on the live cluster).
#
# WHAT THIS DOES AND DOES NOT CATCH. It catches the whole input half: the up-script not
# firing, the label write failing or never being deployed, the convergence timer being dead —
# i.e. every way the tun0 identity can move without Cilium being told. It does NOT catch
# "the label was written and Cilium still did not re-resolve"; nothing in Prometheus can,
# until either the re-steer script exports the map's ifindex through a node-exporter textfile
# collector (DECISIONS-LOG 2026-09-12, hand-off item 4) or a vpn-class black-box probe exists.
# A probe was considered and rejected for now: there is no blackbox-exporter and no probe
# CronJob in this repo, so it means a NEW always-on component whose own failures become a new
# alerting surface — worth doing, but not as the thing that closes a hole today.
#
# WHY A `changes()` COMPARISON RATHER THAN AN EQUALITY TEST. PromQL cannot compare a metric
# VALUE (the live ifindex) against a number embedded in a LABEL VALUE (`...-129`): there is no
# label-to-number conversion, so the level-triggered equality test is not expressible. What IS
# expressible is the same invariant counted over a window: the published label must change at
# least as often as tun0 is re-created. `count(count_over_time(max by (<label>) (...)[1h:1m]))`
# is the number of DISTINCT label values seen in the last hour (verified live: 1 for a label
# that held still, 2 for one that changed value inside the window); the `max by (<label>)`
# wrapper is load-bearing — it aggregates away `pod`/`instance`, so a kube-state-metrics
# restart is not mistaken for a label change. Both sides reduce to a single unlabelled series,
# which is why `and on()` joins cleanly, exactly as `VPNTunnelDown` does.
#
# Consequence, stated plainly: this is bounded by its window. A missed flap is alerted from
# +15m to +1h and then the alert RESOLVES even if egress is still dead. That is a deliberate
# trade against the repo's alert-fatigue history (an unbounded critical on the one channel
# that must stay trustworthy is worse), and it still turns an 80-minute silent outage into an
# email within 15 minutes. The textfile-collector gauge is what would make it level-triggered.

#
# WHAT THESE RULES CLAIM, AND WHY IT NEEDS PINNING IN BOTH DIRECTIONS
# `egress-class=vpn` pods leave through one gateway node's tun0. Cilium resolves that interface to an
# IFINDEX and caches it; an OpenVPN reconnect destroys and re-creates tun0 with a NEW ifindex, and the
# gateway node's up-script publishes `homelab.keithjackson.dev/egress-uplink=<addr>-<ifindex>` so that
# node write forces Cilium to re-resolve. If the label does not follow the tunnel, the cache points at a
# destroyed interface and every vpn-class pod is dropped — while tun0 itself stays up, so VPNTunnelDown
# says nothing. That shape ran ~80 minutes undetected on the dev gateway.
#
# VPNEgressSteeringStale detects it by comparing HOW MANY TIMES tun0's ifindex changed in the last hour
# against HOW MANY DISTINCT `egress-uplink` label values appeared in the same hour. The subtlety worth
# testing is that a label VALUE change is not a sample change: it RETIRES one series and STARTS another,
# so "the label followed the tunnel" shows up as two overlapping series in the window, not as a
# changing value. Tests 1 and 2 are the same tunnel reconnect with and without that second series, so
# they isolate exactly that mechanism — anything that broke the series-counting half would make test 2
# fire, and anything that broke the tun0 half would make test 1 quiet.
#
# VPNEgressUplinkLabelMissing is the WATCHDOG for the rule above: with no uplink label anywhere, the
# staleness comparison has nothing to compare and is structurally INERT — present, evaluating, and
# incapable of firing. Tests 3 and 4 pin that, because an inert critical alert is the failure mode this
# whole group exists to prevent.

If they disagree, the re-steer path is broken — `journalctl -u vpn-egress-resteer` on the
gateway node is the next stop.
### And now something watches it (2026-09-12)
The self-heal closed the datapath hole; it did not close the monitoring one, and a mechanism that
silently stops working is the same outage again. Two rules in `platform/monitoring/alerts.yaml`:
- **`VPNEgressSteeringStale`** (critical, `for: 15m`) — fires when the live tun0 was re-created
more times in the last hour than the `egress-uplink` label changed, i.e. Cilium was never told
about a reconnect. This is the case `VPNTunnelDown` cannot see: tun0 present, bytes flowing,
steering pointed at a destroyed ifindex.
- **`VPNEgressUplinkLabelMissing`** (warning, `for: 30m`) — fires when a node carries
`egress-gateway=true` but no `egress-uplink` label reaches kube-state-metrics, which is the state
in which the rule above would be inert. The watchdog for the watchdog.
Both are gated on a gateway node existing (the same `kube_node_labels` guard `VPNTunnelDown` uses),
so a cluster with no gateway cannot be made to fire them. `egress-uplink` had to be added to
`kube-state-metrics.metricLabelsAllowlist` in `platform/monitoring/kube-prometheus-stack.yaml` for
the label to exist as a metric at all — the two changes must ship together.
**What still is not watched:** "the label was written and Cilium still ignored it." Cilium OSS
exposes no metric carrying the egress map's contents (the map is readable only through
`cilium-dbg bpf egress list`), and the cilium-agent is not scraped on either cluster in the first
place — no `cilium_*` or `hubble_*` series exist. Closing that last gap means either exporting the
map's ifindex from the re-steer script through a node-exporter textfile collector, or a black-box
probe from a vpn-class pod. Neither exists yet.

## Why node 1, and what "mismatched" means here
| slot | part number | size | rated speed | organisation |
|---|---|---|---|---|
| `DIMM1` | Micron **8**ATF2G64HZ-**3G2**E1 | 16 GB | DDR4-**3200** | 1Rx8 |
| `DIMM3` | Micron **16**ATF2G64HZ-**2G6**E1 | 16 GB | DDR4-**2667** | 2Rx8 |
Micron's part numbering carries the proof independently of any inventory doc: the `8ATF` / `16ATF`
prefix encodes rank organisation, the `-3G2` / `-2G6` suffix encodes 3200 vs 2666 MT/s. Capacity is
correct — 32 GB, ~31.1 GiB usable — so **nothing is faulty**. The pair simply runs at the slower 2667
and the ranks differ. `k3s-prod-3` is a matched Crucial pair (`CT16G4SFD8266.C16FE`).
Source: `infra/ansible/_artifacts/node-health/k3s-prod-1.json` records both part numbers; node 3's
records one. **Caveat on the artifacts:** the extraction de-duplicates part numbers, so it can prove
"two different modules" but cannot distinguish one module from two identical ones. Only `dmidecode`
per-slot output settles that, and no raw per-slot block is recorded — which is why verification below
collects it live.
**Node 2's inventory is stale and contradicts itself** (`infra/PROD-PROVISIONING.md` calls it the only
single-DIMM node with one 16 GB Samsung module, yet it reports the same ~31.1 GiB as the others). That
does not change this procedure, but re-inventory node 2 before claiming three-way symmetry.
**DO NOT confuse this with §0b.** The provisioning doc says, correctly, *"do not buy RAM"* — that is
about node 2's old 2.6-GiB-of-16-GB symptom, which was an **EFI memattr kernel bug, not hardware**.
Making node 1's pair matched is a different and legitimate change.
## Before you touch anything
*If `kubectl` hangs from the workstation rather than failing, the OIDC context is the reason — prefix
these with `infra/devcontainer/dev.sh run`.*
**1. Decide what capacity you are installing, because it is a symmetry decision.**
- **2 × 16 GB** keeps all three nodes at 32 GB, which is what `infra/PROD-PROVISIONING.md` §2 assumes
(symmetric nodes; replica placement and the scheduler both lean on it).
- **2 × 32 GB** gives node 1 **64 GB** while nodes 2 and 3 stay at 32 GB — a *new* asymmetry, on the
node that is already the asymmetric one on disk. Workloads will schedule there preferentially.
Allowed, but make it a decision rather than a side effect.
**2. Confirm the cluster can lose this node.** All three nodes are control-plane **and** etcd members,
so losing one leaves quorum at 2 of 3 — survivable, but with **zero further margin**. Do not start if
another node is unhealthy.
kubectl --context k3s-prod get nodes -o wide
# etcd's own view, per node (the house check — embedded etcd metrics on 2381):
for n in 1 2 3; do echo "== k3s-prod-$n"; ssh k3s-prod-$n \
'curl -s http://127.0.0.1:2381/metrics | grep -E "etcd_server_is_leader|etcd_server_has_leader"'; done
Every node must report `etcd_server_has_leader 1`. Note which one reports `etcd_server_is_leader 1`:
if it is node 1, powering it off forces an election, which is normal — you just want to confirm a new
leader afterwards rather than be surprised by it.
**3. Confirm Longhorn is fully healthy first.** Node 1 held **24 replicas** when last measured. Every
volume must be healthy *before* you drain, or you are draining into an already-degraded state.
kubectl --context k3s-prod -n longhorn-system get volumes.longhorn.io \
-o custom-columns=NAME:.metadata.name,ROBUST:.status.robustness,STATE:.status.state
Expect every attached volume `healthy` (a `detached` volume reporting `unknown` is normal for an unused
PVC). **If anything reads `degraded`, stop and let it rebuild.**
**4. Confirm the drain policy is what protects you**, rather than assuming it — it is not pinned in
`platform/longhorn/helmrelease.yaml`, so it is whatever the chart defaults to on this version:
kubectl --context k3s-prod -n longhorn-system get setting node-drain-policy -o jsonpath='{.value}{"\n"}'
You want `block-if-contains-last-replica`. If it reads something more permissive, **set it before
draining** — this is the setting that stops the drain from stranding a volume whose only healthy
replica is on node 1.
**5. Take a fresh backup.** There is player-authored state here now (the Minecraft world on
`crafty-data`). Find the schedule's real resource name rather than guessing it:
kubectl --context k3s-prod -n velero get schedules
kubectl --context k3s-prod -n velero create backup pre-memswap-$(date -u +%Y%m%d%H%M) \
--from-schedule <the daily schedule from above>
Wait for `Completed` with `errors: 0` before continuing.
## Drain
kubectl --context k3s-prod cordon k3s-prod-1
kubectl --context k3s-prod drain k3s-prod-1 --ignore-daemonsets --delete-emptydir-data --timeout=30m
**If the drain blocks, that is the policy doing its job.** Do not reach for `--force` or
`--disable-eviction`. Watch replicas rebuild onto the other two nodes and let the drain proceed:
kubectl --context k3s-prod -n longhorn-system get volumes.longhorn.io \
-o custom-columns=NAME:.metadata.name,ROBUST:.status.robustness | grep -v healthy
Expect real time to pass — this is 24 replicas of actual data movement, and the rebuild path is
deliberately throttled (see `/runbooks/node-io` for which limits are set and which do not exist on
this Longhorn version). Watch the pressure it generates while it runs:
rate(node_pressure_io_stalled_seconds_total{instance="192.168.2.10:9100"}[5m])
The warning threshold is **0.05** and critical is **0.10**; node 1 sat at 0.10 during the incident that
starved etcd. A rebuild storm pushing this up is expected, sustained time above 0.10 is not.
Note what moves, and one thing that happily does not. Verified live 2026-09-19:
kubectl --context k3s-prod get pods -A -l cnpg.io/podRole \
-o custom-columns=POD:.metadata.name,NODE:.spec.nodeName,ROLE:.metadata.labels.role
**No PostgreSQL primary is on node 1.** All three CNPG clusters run 3 instances spread one per node by
required anti-affinity, and node 1 holds a *replica* of each (`keycloak-db-2`, `nextcloud-db-2`,
`semaphore-db-2`). Draining it evicts three replicas and forces **no failover at all** — the best state
this maintenance could ask for. Re-run the command above before you start rather than trusting this
paragraph: primaries move on their own after any restart or failover.
`CNPGPrimariesCoLocated` is currently firing for `k3s-prod-2`, which holds both the `keycloak-db` and
`semaphore-db` primaries. **Do not "fix" that before the swap.** Rebalancing means promoting a replica,
and the only node with spare primary capacity is node 1 — so tidying the alert would put a primary on
the very node you are about to power off and convert a no-failover drain into a two-database failover.
Rebalance *after* node 1 is back and its replicas have caught up.
`sonarr`, `qbittorrent` and `jackett` do sit on node 1 and will reschedule. The UniFi VM
(`virt-launcher-unifi-*`) is there too — it is not live-migratable in practice today, so expect it to be
recreated, which also re-runs its cloud-init.
## Power off and swap
sudo systemctl poweroff # from the node itself, or via the console
HP EliteDesk 800 G5 Desktop Mini, 2 SODIMM slots. **HP's supported population requires `DIMM1` to be
populated** — fill `DIMM1` first, then `DIMM3`. Seat both fully; a partially seated SODIMM in these
machines will POST with one module silently missing.
## Post-swap verification
In order. **Do not uncordon until 1–3 pass.**
**1. The pair is actually matched** — the whole point of the exercise:
ansible-playbook playbooks/node-health.yml -e node_health_hosts=k3s-prod-1 # read-only
or directly on the node:
sudo dmidecode -t memory | grep -E 'Locator|Size|Part Number|Speed|Rank'
Both slots must report the **same Part Number**, the **same Rank**, and — the part that proves the
mismatch is gone — the same `Speed` *and* the same `Configured Memory Speed`. **`Configured Memory
Speed` is the field that matters:** a pair rated 3200 that is being clocked down still reports
`Speed: 3200 MT/s` while `Configured Memory Speed` sits lower. Matched part numbers with a
below-rated configured speed means the job is not done.
**2. Capacity is what you installed.**
kubectl --context k3s-prod get node k3s-prod-1 -o jsonpath='{.status.capacity.memory}{"\n"}'
Roughly 31.1 GiB reported for 2 × 16 GB, roughly double for 2 × 32 GB. If it reads about half what you
installed, a module is not seated or not detected — power off and reseat rather than debugging it in
software, because the scheduler will believe whatever capacity is reported.
**3. No new memory errors.** These machines are non-ECC, so this is a sanity check, not a guarantee:
sudo journalctl -k -b | grep -iE 'mce|memory error|ECC|Hardware Error'
**4. Rejoin the cluster.**
kubectl --context k3s-prod uncordon k3s-prod-1
kubectl --context k3s-prod get nodes
ssh k3s-prod-1 'curl -s http://127.0.0.1:2381/metrics | grep -E "etcd_server_is_leader|etcd_server_has_leader"'
`Ready` on the node and `etcd_server_has_leader 1` from node 1's own etcd before you call this done.
**5. Longhorn returns to fully healthy.** Rebuilds run back onto node 1, and this is the phase that
historically produced I/O pressure on this node — watch it rather than walking away:
kubectl --context k3s-prod -n longhorn-system get volumes.longhorn.io \
-o custom-columns=NAME:.metadata.name,ROBUST:.status.robustness | grep -vc healthy
with the same PSI query from the drain section. `/runbooks/node-io` records what the post-SSD-swap
18-replica rebuild measured, for comparison.
**6. Alerts quiet.** The only thing that should be firing is `Watchdog`:
kubectl --context k3s-prod -n monitoring exec prometheus-kube-prometheus-stack-prometheus-0 \
-c prometheus -- /bin/promtool query instant http://localhost:9090 'ALERTS{alertstate="firing"}'
## If it goes wrong
- **Node does not POST**: reseat both modules; failing that, put the original pair back. The old DIMMs
are known-good — the mismatch was a consistency/performance issue, not a fault.
- **Node POSTs with half the memory**: one module not detected. Power off and reseat.
- **Node rejoins but volumes stay degraded**: `/runbooks/longhorn-degraded`. Do **not** drain a second
node while rebuilds are outstanding — that loses quorum and replicas at the same time.
- **Abort mid-drain**: `kubectl --context k3s-prod uncordon k3s-prod-1` is safe any time before poweroff.
## Update the record when you are done
`infra/PROD-PROVISIONING.md` carries the DIMM inventory table and the "not a matched pair" paragraph.
Both become wrong the moment this succeeds. Update them in the same change that records the swap —
stale hardware documentation is exactly what made node 2's inventory untrustworthy.

# plex-claim — claiming the Plex Media Server inside the 4-minute token window
**Alert:** none. This is an **operator procedure**, not an incident page — it is indexed here because
it is the page you need at the moment you need it, with a stopwatch running.
**Files:** `catalog/plex.yaml` (env `PLEX_CLAIM`), `apps/wave-0/plex-claim-secret.sops.yaml`
(the SOPS Secret `plex-claim`, key `PLEX_CLAIM`), `apps/wave-0/plex.yaml` (the rendered golden).
## What this means here
Plex will not let you **create libraries** over the mounted bulk media share while the server is
**unclaimed** — the 8.33 T NFS tree at `/media` is there, readable, and unusable. Claiming binds the
server to a plex.tv account. It is a **one-shot** operation: the token is exchanged once for a durable
`PlexOnlineToken` written into `Preferences.xml` on the `plex-config` Longhorn PVC, and from then on
the `PLEX_CLAIM` env is **ignored on every start** (upstream gate:
`[ ! -z "${PLEX_CLAIM}" ] && [ -z "${token}" ]` in `root/etc/cont-init.d/40-plex-first-run`).
**A `https://plex.tv/claim` token lives ~4 minutes.** That is shorter than commit → push → Flux's
10-minute reconcile interval → pod roll if you let those run on their own timers, which is why this
page exists: every step below is written to be run back-to-back, with the reconcile **forced** rather
than waited for. Budget: token in hand at T+0, pod restarted by roughly T+2:00.
**An expired or wrong token does not break anything.** Verified against the image's own first-run
script (and the copy inside `plexinc/pms-docker:latest`): a failed exchange gets a 403 with an empty
body, `curl`'s status is never checked, the token `sed` yields empty, the `if` does not fire, there is
no `else` and no `exit 1`, and the script (no `set -e`) exits 0. The pod comes up **unclaimed and
serving**. So a burnt token costs you one more attempt, not an outage — and the repo deliberately
ships a **placeholder** in that Secret for exactly this reason (the env `secretKeyRef` has no
`optional`, so the Secret must always exist even when its value is useless).
## Running the commands in this runbook
`kubectl` does not work on the operator workstation. The toolchain lives only in the pinned dev
container, and the host's `k3s-oidc` context hangs on a browser prompt once its token expires — that
hang is not the cluster being down. Every command below runs as:
infra/devcontainer/dev.sh run bash -c 'kubectl --context k3s-prod get nodes'
Always pass `--context k3s-prod` explicitly. `dev.sh` merges BOTH clusters into one kubeconfig and
picks a current-context per invocation, and that default has already changed once (k3s-dev until dev
was decommissioned on 2026-09-13, k3s-prod now). Do not run two `dev.sh` invocations at once.
Mutating `kubectl` and `flux reconcile` are blocked for agents here. **This whole page is operator
work** — the reconcile and the pod roll below are deliberate operator actions, and the durable change
is still a git change.
## First commands
**Before spending a token, find out whether the server is already claimed.** This prints only the
attribute NAME, never its value — do not widen it to print the token:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex exec deploy/plex -- sh -c \
"grep -o PlexOnlineToken= \"/config/Library/Application Support/Plex Media Server/Preferences.xml\" | head -1"'
```
`PlexOnlineToken=` printed ⇒ **already claimed**; stop, there is nothing to do and no token to burn.
Empty output ⇒ unclaimed, continue.
Is the workload healthy enough to claim at all, and is the wave reconciling?
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex get deploy,pod,pvc'
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n flux-system get kustomization apps-wave-0'
```
## The 4-minute procedure
Have this page open and do not stop between steps.
1. **T+0 — get the token.** Sign in to plex.tv as the account that should OWN this server, open
<https://plex.tv/claim>, copy the `claim-…` string. The clock starts now.
2. **T+0:15 — put it in the Secret**, in place, encrypted, without it ever touching a plaintext file:
```
infra/devcontainer/dev.sh run sops apps/wave-0/plex-claim-secret.sops.yaml
```
Replace the `PLEX_CLAIM:` value (the placeholder `replace-me-with-a-fresh-plex-tv-claim-token`, or
a previous expired token) and save. `sops` re-encrypts on write to the committed age recipient.
3. **T+0:45 — commit and push.** `git push origin main` **is** the deploy; there is no other apply
step.
```
git add apps/wave-0/plex-claim-secret.sops.yaml
git commit -m 'chore(plex): fresh plex.tv claim token'
git push origin main
```
4. **T+1:00 — force the reconcile immediately. This is the one command that saves the window** — it
pulls the new commit and re-applies wave 0 instead of waiting up to 10 minutes for the interval:
```
infra/devcontainer/dev.sh run bash -c \
'flux --context k3s-prod -n flux-system reconcile kustomization apps-wave-0 --with-source'
```
`--with-source` is the load-bearing flag: it reconciles the `flux-system` GitRepository first, so
the Kustomization applies **your commit** and not the previously-fetched revision.
5. **T+1:30 — roll the pod.** This step is **mandatory and easy to forget**: a changed Secret does
**not** restart anything. `PLEX_CLAIM` is injected by `secretKeyRef` and read only at container
start, and the Deployment's pod template is byte-identical across this change, so Flux applies the
new Secret and the running pod keeps the old value forever.
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex rollout restart deployment/plex'
```
6. **T+2:00 — confirm the exchange happened**, in the new pod's init log:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex logs deploy/plex --since=5m | grep -i -e claim -e token'
```
* `Attempting to obtain server token from claim token` **and** `Token obtained successfully`
⇒ **claimed.** Re-run the First-commands `PlexOnlineToken=` check to confirm it persisted, then
create the libraries over `/media/movies`, `/media/tv`, `/media/photos`.
* `Attempting to obtain server token from claim token` with **no** success line ⇒ the token was
expired or invalid. Nothing is broken; go back to step 1 with a new token.
* **Neither line** ⇒ the exchange was skipped, which means `/config` already had a
`PlexOnlineToken` (already claimed) or the env did not reach the container. Check the pod actually
has the variable, by NAME only:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex get pod -l app.kubernetes.io/name=plex \
-o jsonpath="{.items[0].spec.containers[0].env[*].name}"'
```
## Likely causes, most likely first
When the claim does not take, in order of how often it is the answer here:
1. **The token expired** — you spent more than ~4 minutes, usually in step 3 or waiting on step 4.
Symptom: the "Attempting…" line with no success line. Remedy: a new token, and force the reconcile
rather than waiting for it.
2. **The pod was never restarted** (step 5 skipped). Symptom: no claim log lines at all from a pod
whose `AGE` predates your push. The Secret is correct in git and in the cluster and the running
container still holds the placeholder.
3. **Flux had not applied the commit yet** when you rolled the pod — step 5 run before step 4
finished, so the new pod read the OLD Secret. Check
`kubectl --context k3s-prod -n flux-system get kustomization apps-wave-0 -o jsonpath='{.status.lastAppliedRevision}'`
against your commit, then roll again.
4. **Already claimed** — the exchange is gated on `PlexOnlineToken` being absent from `/config`, so a
server claimed earlier ignores every later token silently. This is the benign case.
5. **`plex.tv` unreachable.** The upstream `curl` has no `--max-time`/`--connect-timeout`, so a stalled
connection can leave the container sitting in cont-init with **nothing listening on 32400** — the
one genuine hang risk in this path. Symptom: pod Running but never Ready, log stops after
"Attempting…". Check egress (`plex` is `egress: internet`) rather than re-rolling repeatedly.
6. **Wrong plex.tv account.** The claim succeeds and binds the server to whoever was signed in at
step 1. Unclaiming is a plex.tv-side operation on that account — see "escalate or stop".
## When to escalate or stop
- **Stop after two failed token attempts** and fix the timing, not the token. The third rushed attempt
is how people start editing live Secrets by hand, which leaves the cluster holding a value that is
in no git commit — precisely the drift `qbittorrent-bootstrap` had to be recovered from.
- **Never `kubectl edit`/`patch` the `plex-claim` Secret in the cluster, and never
`kubectl create secret` it.** Everything durable goes through the SOPS file; a live-only Secret is
reverted (or adopted with the wrong value) on the next reconcile.
- **Never `sops -d` this file into a terminal, a log, or a shared screen**, and never widen the
`PlexOnlineToken=` check into one that prints the value. The token is a plex.tv account credential.
- **If the server got claimed to the wrong account, stop and get the operator.** Reversing it means
removing the server from that account on plex.tv and clearing `PlexOnlineToken` from
`Preferences.xml` on the PVC — a destructive edit of app state on the replicated tier, not a git
change.
- **Do not delete the `plex-config` PVC to "start clean".** It holds the library database, metadata
and watch state (`policy: daily-offcluster`), and it is expensive to rebuild. The claim is a
two-line pref, not a reason to lose the DB.
- After a successful claim, **leave the expired token in the SOPS file**. It is inert (the exchange is
skipped once claimed) and the Secret must keep existing, because the env `secretKeyRef` has no
`optional` — deleting it would put the pod into `CreateContainerConfigError`.

# vpn-egress-stale — VPN egress steering did not follow the tunnel
**Alerts:** `VPNEgressSteeringStale` (critical, 15m) and `VPNEgressUplinkLabelMissing` (warning, 30m)
**File:** `platform/monitoring/alerts.yaml`
**Related:** `/runbooks/vpn-down` is for the tunnel being DOWN. This page is for the tunnel being **up**
while the pods that must use it have no egress at all.
## What this means here
`egress-class=vpn` pods leave the cluster through one gateway node's `tun0`, selected by the
`vpn-egress-steering` CiliumEgressGatewayPolicy. Cilium resolves that interface to an **ifindex** and
caches it. When OpenVPN reconnects it destroys and re-creates `tun0`, which gets a **new ifindex** — and
Cilium does not re-resolve on its own. The gateway node publishes
`homelab.keithjackson.dev/egress-uplink=<tun0 address>-<ifindex>` from the OpenVPN up-script on every
connect, and that node write is what makes Cilium re-resolve.
If the label write does not happen, the cache keeps pointing at a destroyed interface. **`tun0` looks
perfectly healthy the whole time** — it is up, it has an address, `VPNTunnelDown` stays quiet — while
every vpn-class pod is silently dropped. That exact shape ran for roughly **80 minutes** undetected on
the dev gateway, which is why these two alerts exist.
`VPNEgressSteeringStale` compares how many times `tun0`'s ifindex changed in the last hour against how
many distinct `egress-uplink` label values appeared in the same hour. More tunnel changes than label
changes means a reconnect happened that the label did not follow.
**`VPNEgressUplinkLabelMissing` is the watchdog for that comparison.** If the label is absent entirely,
the staleness rule has nothing to compare against and is **inert** — present, evaluating, and incapable
of firing. So the warning matters more than its severity suggests: it means your critical alert is
switched off.
Today's gateway is **`k3s-prod-3`** (`homelab.keithjackson.dev/egress-gateway=true`), and the policy has
been in place since early September. It is a **singleton** — there is no second gateway to fail over to.
## First commands
Run cluster commands through the pinned toolbox, which supplies the kube context:
```
./infra/devcontainer/dev.sh run kubectl --context k3s-prod get nodes \
-L homelab.keithjackson.dev/egress-gateway -L homelab.keithjackson.dev/egress-uplink
```
You want exactly one node carrying `egress-gateway=true`, and that same node carrying a non-empty
`egress-uplink` of the form `<address>-<ifindex>`.
```
# 2. what Cilium currently believes, on the gateway node itself
ssh k3s-prod-3 'sudo cilium-dbg bpf egress list'
ssh k3s-prod-3 'ip -o link show tun0' # the REAL ifindex, first field
```
Compare the ifindex in the label and in `bpf egress list` against `ip link`. **A mismatch is the whole
bug.**
```
# 3. is the re-steer mechanism itself alive?
ssh k3s-prod-3 'systemctl status vpn-egress-resteer.service vpn-egress-resteer.timer --no-pager'
ssh k3s-prod-3 'journalctl -u vpn-egress-resteer --since -2h --no-pager | tail -30'
```
```
# 4. are vpn-class pods actually broken, or only the metric?
./infra/devcontainer/dev.sh run kubectl --context k3s-prod get ciliumegressgatewaypolicies.cilium.io \
vpn-egress-steering -o yaml | head -40
```
Prove egress from a pod the policy selects rather than inferring it — the observable symptom is
"outbound traffic silently disappears", so test outbound traffic:
```
./infra/devcontainer/dev.sh run kubectl --context k3s-prod -n qbittorrent exec deploy/qbittorrent -- \
sh -c 'curl -s --max-time 10 https://ifconfig.me || echo EGRESS-FAILED'
```
That should return the **VPN provider's** address. The gateway VIP or a timeout both mean egress is
broken; your own ISP address means the kill-switch is not holding and traffic is leaking, which is worse
than a drop — see `/runbooks/vpn-down`.
## Likely causes, most likely first
1. **A tunnel reconnect that the label did not follow.** The common case, and what the alert is built to
catch. The OpenVPN up-script either did not run or could not write the node label (RBAC, expired
kubeconfig on the node, API unreachable at that moment). Check `journalctl -u vpn-egress-resteer` and
the up-script's own log around the reconnect time.
2. **Cilium cached a dead ifindex despite the label changing.** The label write happened but the
re-resolution did not take. Forcing any node-label write makes Cilium re-resolve — that is the same
lever the up-script pulls, so it is a safe nudge, not a workaround:
./infra/devcontainer/dev.sh run kubectl --context k3s-prod annotate node k3s-prod-3 \
egress-resteer-nudge="$(date -u +%s)" --overwrite
Re-applying the CiliumEgressGatewayPolicy has the same effect. Re-check `bpf egress list` after.
3. **`metricLabelsAllowlist` lost the label** (this fires `VPNEgressUplinkLabelMissing`, not the stale
alert). kube-state-metrics exposes **no** custom node labels by default; the allowlist entry in
`platform/monitoring/kube-prometheus-stack.yaml` is what publishes them. If that entry is edited or
dropped, `kube_node_labels` carries no `label_homelab_keithjackson_dev_egress_uplink` and the critical
alert goes quiet without anything looking broken. Confirm what is actually exported:
./infra/devcontainer/dev.sh run kubectl --context k3s-prod -n monitoring exec \
prometheus-kube-prometheus-stack-prometheus-0 -c prometheus -- \
/bin/promtool query instant http://localhost:9090 'kube_node_labels'
Note that KSM does **not** restart on a ConfigMap-only change; the deployment carries no checksum
annotation over it, so a `rollout restart -n monitoring deploy/kube-prometheus-stack-kube-state-metrics`
is required after editing the allowlist.
4. **The gateway node was replaced or relabelled.** If `egress-gateway=true` moved, the up-script must be
installed on the new node (`infra/ansible/roles/vpn_egress_gateway`). A gateway label with no
up-script behind it produces exactly this alert on the next reconnect.
## When to escalate or stop
- **Stop and do not "fix" it by deleting the policy.** Removing `vpn-egress-steering` does not restore
egress; it sends vpn-class traffic out of your **own** ISP connection, which is the leak the class
exists to prevent. A broken tunnel that drops traffic is the intended failure mode.
- **Escalate to a maintenance window** if the ifindex mismatch returns after every reconnect. That is the
up-script or its RBAC, not a transient, and chasing it live means repeatedly breaking egress for the
vpn-class workloads.
- **This is a singleton gateway.** There is no failover. If `k3s-prod-3` needs to be drained while this is
unresolved, accept that vpn-class egress is down for the duration rather than improvising a second
gateway under time pressure.
- If `VPNEgressUplinkLabelMissing` is firing and you cannot restore the label quickly, say so explicitly
in the incident notes: for as long as it is missing, **`VPNEgressSteeringStale` is not watching
anything**, so the absence of that critical alert proves nothing.

- `internal` renders **no public DNS record** and is never port-forwarded (PiHole resolves it to the
internal Gateway VIP).
- **HOW "no public DNS record" IS MADE TRUE, since it was prose only until 2026-09-14.** Every
HTTPRoute rendered for an `internal` service carries ExternalDNS's own controller annotation with
a value other than the one ExternalDNS claims:
external-dns.alpha.kubernetes.io/controller: none
ExternalDNS v0.21.0 (`source/annotations/processors.go`) skips any source object whose
`controller` annotation is present and `!= "dns-controller"`, and `source/gateway.go` applies that
check **inside `Endpoints()` before any hostname is resolved** — so the route never becomes an
endpoint for any name it declares. `source/service.go` applies the identical check, which covers
the second configured source. It is derived **from `exposure` and nothing else**
(`catalog/render.py` `_externaldns_route_annotations`), so the operator's one declaration decides,
a service that OMITS `exposure` inherits the `internal` default and is likewise unpublishable, and
there is no per-service list to forget to extend. `ci/render-golden.sh` proves `apps/` reproduces
from `catalog/`, so an `internal` service cannot exist in the applied tree without it, and
`conformance/tests/l0-static/internal-services-publish-no-public-dns` re-proves both directions
(present on internal, **absent** on public) on every gate run.
- The route itself, the wildcard TLS and LAN reachability are **unchanged** — only the public
record is withdrawn. The internal split-horizon answer is Pi-hole's job (R-DNS-03), which is why
withdrawing these records requires Pi-hole to be answering the LAN authoritatively first: the
zone has no `*.home.keithjackson.dev` wildcard, and `*.keithjackson.dev` does not match two
labels, so a withdrawn name is a public NXDOMAIN with no fallback.
- Why not a cluster-wide ExternalDNS opt-in filter (`labelFilter`, which v0.21.0 supports for
both configured sources): seven published names come from hand-authored `platform/`/`apps/`
manifests that carry no `exposure` field for a renderer to read, and an opt-in filter deletes
all seven the moment it is set. Per-resource exclusion has exactly the blast radius of the
defect. The filter stays available as hardening once those seven are adjudicated — see
`platform/externaldns/helmrelease.yaml` and the register in the L0 check.
- `public` renders the record but the renderer does **not** yet set a target: the record still
resolves to the shared Gateway VIP, i.e. an RFC1918 address, so a `public` service is not in fact
publicly reachable. Fixing that is **not** a renderer change on v0.21.0 —
`source/gateway.go` reads `external-dns.alpha.kubernetes.io/target` only from the **Gateway** (and
a ListenerSet), never from an HTTPRoute, so a per-service target override is not expressible while
the public services share the `shared` Gateway. The open decision is recorded in
`platform/externaldns/helmrelease.yaml`.
