Both ServiceDefinitions guarded their Keycloak OIDC registration with an UNESCAPED
braced expansion:
if [ -z "${GITEA_OIDC_CLIENT_SECRET:-}" ]; then # gitea
if [ -z "${NEXTCLOUD_OIDC_CLIENT_SECRET:-}" ]; then # nextcloud, then exit 0
apps-wave-0/1 both declare postBuild.substituteFrom: cluster-vars, and neither name is a
cluster-vars key — so Flux's envsubst substituted them away AT RECONCILE TIME, long
before the container ever ran. Verified in the LIVE cluster: the deployed Deployments
literally contain
if [ -z "" ]; then
which is always true. The entire OIDC registration block has been skipped on EVERY boot
of both apps.
WHY NOBODY NOTICED: both apps DO have the provider registered — `gitea admin auth list`
shows keycloak/OAuth2/true and `occ user_oidc:provider` shows the keycloak provider.
Those live in each app's own database, persisted from an earlier successful registration.
SSO works today and DECISIONS-LOG is not wrong. But the idempotent re-registration is
dead, so any PVC rebuild, DB restore, or fresh cluster build comes up with NO OIDC and
only the break-glass local admin. A PROD BUILD FROM THIS REPO WOULD SILENTLY HAVE NO SSO
on gitea or nextcloud.
The irony: the surrounding code was hardened twice — see its own comments about a "silent
first-boot RACE", the verify-then-retry loops, the marker files. All of that hardening was
unreachable, because the guard above it always evaluated true.
Not a regression from the recent R-ENV-02 tokenization — introduced 2026-08-27 (8738871).
FIXED AT THE RIGHT SEAM: apps/wave-0/gitea.yaml and apps/wave-1/nextcloud.yaml are
RENDER-GENERATED, so the fix is in catalog/*.yaml and the goldens are regenerated.
Escaped to $${...}, the convention documented in clusters/base/apps-vms.yaml. Post-envsubst
the container now receives the intended `${VAR:-}` instead of `""`.
STRICT MODE WOULD NEVER HAVE CAUGHT THIS. Flux deliberately exempts default-providing
operators (-, :-, +, :+, =, :=, ?, :?) from StrictPostBuildSubstitutions, because they
"intentionally handle the unset case". So a targeted check was required.
MADE UN-REPEATABLE IN THE RENDERER: catalog/render.py gains a substitution-safety section
wired into emit(), so every render path refuses to emit a manifest containing a braced
expansion that is not exactly ${KNOWN_KEY} for a key read LIVE from cluster-vars (no
hardcoded copy to drift; unreadable => empty set => fail-closed). Dollar-runs are counted
properly ($$ is a literal $ to envsubst, so odd runs are flagged and even runs are not),
and indexed forms get their own hard-error message. Nine new --selftest assertions,
including the exact regression. Proven to bite: rendering the pre-fix catalog files from
HEAD now exits 1 with the precise diagnosis.
Sweep: the complete substituted surface was enumerated from every Kustomization's path.
catalog/ contains exactly TWO braced expansions and both were these bugs; every other
braced expansion on a substituted path is a declared cluster-vars key (zero typos, zero
undeclared names); existing $${UOS_URL} escapes verified intact.
Verified: --selftest PASS; canonical render is byte-identical to the committed apps/ for
all 10 onboarded services; the three L1 render checks pass.
NEXT RECONCILE: both pod templates change, so gitea (wave 0) and nextcloud (wave 1) roll —
strategy: Recreate on RWO Longhorn PVCs, so expect a brief single-pod outage each. The
OIDC block then executes for the first time in these apps' deployed lifetime. Both paths
are idempotent (gitea takes auth update-oauth on the existing id; nextcloud's
user_oidc:provider is create-or-update), so the expected result is a no-op re-write plus
the verify loop logging success. If the SOPS client secret ever diverged from Keycloak's,
this is when it gets corrected instead of silently left stale. Tail both pods after merge.

Merging PR #4 put cilium agents into Init:Error on 2/3 dev nodes for ~6 minutes. Self-healed;
cluster fully green. Recorded because the mechanism is systemic and far more dangerous on a
cold prod bootstrap.
Root cause: cluster-vars (which DEFINES a knob) is owned by the flux-system Kustomization,
while platform/ (which REFERENCES it) is owned by the platform Kustomization, with no
dependency ordering between defining a variable and using it. Flux post-build substitution is
NON-STRICT by default, so during the window where platform rendered the new manifest against
the old cluster-vars, ${K3S_API_HOST} became the EMPTY STRING. Cilium upgraded with
k8sServiceHost: "" and fell back to ClusterIP 10.43.0.1 — which only the Cilium agent can
translate, and that agent was the thing restarting. Its config init container then could not
reach the API server at all.
Proven by the HelmRelease config digest going e83bf695 -> eebd6c88 -> e83bf695: the config
changed and then changed back to BYTE-IDENTICAL. The pre-merge byte-identity verification was
correct — the steady state is identical; the damage was a transient intermediate render.
optional: false does NOT protect against this: it requires the ConfigMap to exist, not that
every referenced key is defined.
Fix recommended, NOT applied unilaterally: enable the StrictPostBuildSubstitutions feature gate
on kustomize-controller so an undefined variable FAILS the Kustomization instead of silently
emptying it — fail-closed, per this project's own doctrine. Requires first proving every ${VAR}
in every substituted path is defined or correctly escaped, or it would fail legitimate embedded
shell expansions. Interim discipline: add a knob in one commit, reference it in a later one.

1. PROD NODE DNS = 8.8.8.8 + 1.1.1.1 (operator, 2026-09-01). Two INDEPENDENT public
upstreams, so the single-upstream SPOF that broke containerd pulls and CoreDNS
forwarding on dev cannot recur. Prod deliberately differs from dev, which is
PiHole-first because dev needs the local jackson.lan zone.
SCOPE CORRECTED IN THE COMMENTS. Three resolvers answer *.home.keithjackson.dev and
only one is configured here:
pods -> CoreDNS -> platform/coredns/coredns-custom.yaml, whose `template` plugin
answers the WHOLE zone with ${GATEWAY_VIP}. Self-contained in-cluster;
PiHole is NOT in this path. Prod is already correct (.20).
LAN -> PiHole. Not a cluster concern.
nodes -> THIS FILE.
The one thing public node DNS breaks: the k3s API SERVER is a node process carrying
oidc-issuer-url=https://keycloak.home.keithjackson.dev/realms/homelab and reaches the
issuer through the NODE resolver, so prod would get the PUBLIC record instead of the
prod Gateway VIP — breaking kubectl OIDC SSO. Dev avoids this only because its node
resolver IS PiHole. Not blocking (prod has no cluster or Keycloak yet); options are
recorded in PROD-PROVISIONING.md §4 for the operator to pick.
2. SERVICE VIPs DECIDED: UNIFI_L4_VIP 192.168.2.21, CRAFTY_L4_VIP 192.168.2.22 — the
first two addresses after GATEWAY_VIP (.20), mirroring dev's .53/.54/.55 ordering
within the .20-.30 pool. S3_BACKUP_ENDPOINT stays TBD-PROD-* : no prod backup target
exists, and dev's versitygw is across the pfSense boundary on the dev host, so it is
not DR for prod.
3. PROD BECOME VAULT committed, ansible-vault encrypted, matching the hypervisor and
proxmox_hosts pattern. Verified working: `ansible k3s_prod -m command -a 'id -un'
--become` returns root. The L0 no-plaintext-secrets check asserts every ansible
vault.yml starts with $ANSIBLE_VAULT, so this stays honest by gate.
4. TOOLCHAIN GAP FIXED: the devcontainer image does NOT ship the Galaxy collections, so
EVERY ansible play died at parse time on community.general.modprobe. ansible.cfg now
sets collections_path = collections, and the collections are installed there from the
existing collections/requirements.yml (gitignored — pinned by requirements, fetched at
setup, vendored bytes are not source).
5. DRIVE HEALTH MEASURED and recorded in §2 with the raw attribute table so the numbers
are auditable. Verdict: usable, but not for production etcd/Longhorn state — 31% of
rated life consumed, 15 grown bad blocks, 187 erase failures, and 32 unexpected power
losses on a consumer drive with NO power-loss protection, in a single failure domain.
etcd is the worst possible tenant: it fsyncs constantly and unclean power loss without
PLP is exactly how a member corrupts.
6. NON-ECC RAM: RISK ACCEPTED by the operator, recorded as a CLOSED decision, not an open
item — do not re-litigate. Rationale: 3-node k3s homelab, not enterprise; corruption on
one node is outweighed by the other two and causes node ejection. That holds for the
dominant mode (etcd raft CRC + quorum; Longhorn 3 replicas + hard anti-affinity +
rebuild). Recorded residual: corruption introduced UPSTREAM of replication replicates
faithfully to all three replicas, so quorum sees no disagreement — low probability, and
the only mitigation is different hardware. Follow-up noted: Longhorn's
snapshotDataIntegrity is left at the chart default rather than set explicitly, and it
is the mechanism that operationalises the operator's own argument.

The first real SMART run FAILED k3s-prod-1's drive on reallocated=61440. That verdict
was WRONG, and the failure mode is instructive: the check trusted a VENDOR-DEFINED raw
value as if it were an ATA-standard sector count.
Micron TN-FD-20 ("SMART Attributes for the C400 SSD") names attribute 5 "Reallocated
BLOCK Count" and defines its raw as grown-bad-blocks x Block_Sector_Count, where
Block_Sector_Count is 256 x 16 = 4096 for the 128Gb-NAND parts (256GB/512GB). This is
the 512GB C400-MTFDDAC512MAM: 61440 / 4096 = 15. Triply corroborated on the drive itself
— attr 170 Grown_Failing_Block_Ct = 15, attr 196 Reallocated_Event_Count = 15, attr 5
normalised value 100 against thresh 10, and `when_failed` empty on every attribute.
FIFTEEN grown bad blocks, not sixty-one thousand bad sectors.
smartctl(8) states it outright: since ATA/ATAPI-4 rev 4 the meaning of raw Attribute
fields is "entirely vendor-specific". So a raw value can never be a portable verdict.
FAIL now comes only from signals that mean the same thing on every drive: the drive's own
smart_status.passed; NORMALISED value vs the MANUFACTURER's own threshold via smartctl's
when_failed ("now"/"past"/""), split Pre-fail -> FAIL and Old_age-or-past -> WARN; the
ATA-standard counters 197/198/187 (199 CRC is WARN-only — it is link, not media); and for
NVMe critical_warning / media_errors / percentage_used. Wear reads from the NORMALISED
lifetime indicator (202/231/233, or NVMe percentage_used) — a percentage by definition.
Vendor raw counts are still collected and PRINTED WITH THEIR NUMBERS, and may raise a
WARN, but can never drive a FAIL. Attribute 5's raw is now shown beside the normalised
reading that contradicts it, labelled vendor-encoded, with a mechanically-derived
"(= 15 x 4096)". Endurance attributes are matched by THE NAME smartctl's drivedb resolved
for that model, not by bare ID — drivedb is the portability layer; on an unrecognised
drive the name is Unknown_Attribute, nothing matches, and the field stays null with no
claim made. The STORAGE section now prints 170/172/173/174/189/206, whose previous
omission is exactly what let the misread stand unchallenged.
Also documented from TN-FD-20: on this family attr 197 "will always be 0, as reallocation
will be done on-the-fly" — so pending=0 is NOT evidence of health here. The role reports
the number and infers nothing from it.
Branches real hardware cannot exercise were verified with a harness rendering the actual
role expressions against synthetic smartctl payloads: virtio/no-stdout -> SKIP; NVMe
healthy -> PASS; NVMe degraded -> FAIL; a genuinely dying ATA drive (attr 5 normalised 8
<= thresh 10, pending 48) -> FAIL driven by the threshold trip and standard counters, not
the raw; unknown-vendor attrs -> PASS with the unnamed counter ignored; failed-in-the-past
-> WARN.
NEW VERDICTS. k3s-prod-1: 0 FAIL / 4 WARN / 12 PASS / 1 SKIP — SMART is a WARN naming the
real findings (31% of rated life consumed, 15 grown bad blocks, 187 erase failures, 32
unexpected power losses on a drive with no power-loss protection). k3s-dev-1: unchanged,
all three virtio disks still SKIP with their stated reason.
BREAKING (JSON artifact): the fact `reallocated_sectors` is renamed and gone — that name
asserted a unit ATA does not guarantee. Replaced by realloc_attr (the whole attribute,
normalised + raw), realloc_events, and grown_bad_blocks. Nothing in the repo reads it.

Records what landed, the numbers (coverage 37->40/51, safety-critical scaffolds 1->0,
PROVEN still 0 by design), the corrections made mid-session so they are not re-litigated

Re-authors the fix stranded on origin/fix/node-dns-resilient-upstream (7a34590). That
commit was NOT landed: it wrote a netplan drop-in and ran `netplan apply`, but netplan
does not exist on these nodes any more (Debian 13 trixie generic cloud image; not in
node_baseline_packages). Landing it would have failed the handler with command-not-found
and BROKEN node-baseline.yml on every node — worse than not landing it. Its dev-LAN
literals also sat in role defaults, which prod inherits, pointing prod nodes at a PiHole
on a network they cannot reach.
The underlying problem is real and verified: a SINGLE upstream resolver is a hard SPOF.
PiHole answers jackson.lan instantly but its external recursion flaps — 0/25 for public
names (registry-1.docker.io, quay.io, ghcr.io) while gitea.jackson.lan resolved 5/5 —
breaking containerd image pulls and CoreDNS `forward . /etc/resolv.conf`.
MECHANISM DETECTION (new `dns` tag in node_baseline). Five read-only probes feed one
set_fact yielding three outcomes, because the two environments no longer share a resolver
stack (dev-1 is behind resolved's 127.0.0.53 stub; prod-1 has a direct resolv.conf and no
cloud-init at all):
* systemd-resolved — resolved running AND owning /etc/resolv.conf (proven by the
symlink pointing into /run/systemd/resolve/, or by every nameserver being a resolved
loopback). Writes resolved.conf.d/99-k3s-dns.conf with an ordered DNS=, Domains=, and
FallbackDNS= EXPLICITLY EMPTIED so systemd's compiled-in public resolvers can never
silently bypass the local zone and ad-blocking.
* resolv-conf-file — plain directly-managed file (prod's shape). Ordered nameserver
lines + options timeout:2 attempts:2, backup: true. Deliberately NO `rotate`, which
would destroy PiHole-first ordering.
* contended — resolvconf/openresolv present or NetworkManager active. Writes NOTHING
and fails loudly: a change that silently gets reverted is worse than no change.
Resolved-running-but-not-owning-resolv.conf correctly falls through to the file branch.
Ordering is the policy that keeps the local zone working — the second server is only
consulted after the first fails, so a gateway NXDOMAIN can never beat PiHole to a
jackson.lan answer.
SEAMS. Dev values in role defaults ([192.168.1.18, 192.168.1.1], search jackson.lan);
prod values in inventory/group_vars/k3s_prod/vars.yml. NOT cluster-vars — that ConfigMap
is consumed by Flux postBuild for platform/ and apps/, and no Ansible code reads it.
PROD'S SECOND UPSTREAM IS AN OPEN OPERATOR DECISION and is left as a loud
BLOCKED-pending-second-upstream placeholder, the same precedent as the node_baseline disk
devices, with a dns-tagged assert that stops the play before any file is written. A
public resolver was NOT invented as a default: it would bypass the local zone, which is a
decision, not a default. PROD-PROVISIONING.md §4 was rewritten (the old bullet pointed at
the now-dropped branch) to state the choice, including that prod routing to the dev
PiHole is unverified across the pfSense boundary.
tofu: servers = [var.dns_server, var.network_gateway] — the one hunk of the old branch
worth taking as-is. Dev-only by nature.
ALSO FIXES A FALSE WARN THIS WOULD OTHERWISE CREATE: node_health_collect.py parsed
/etc/resolv.conf only, so on dev it read the 127.0.0.53 stub and would report a permanent
single-upstream WARN even after a correct fix. It now asks resolvectl for the real
upstreams when it sees the stub — and if that fails, nameservers is NULL with the reason
recorded, never the stub and never a guess. assess.yml turns null into SKIP, not WARN and
not PASS. The honesty discipline is preserved exactly.
Verified with NO play run against any node: syntax-check + yamllint + tofu fmt clean;
--tags packages still selects ONLY the apt task (the prod package-floor escape hatch
bypasses DNS entirely); --list-hosts unchanged; -c local simulation driving the REAL
detection expression and REAL file bodies extracted from the role by script (so the test
cannot drift) passes all 5 scenarios — dev stub -> systemd-resolved, prod shape ->
resolv-conf-file, NetworkManager and resolvconf -> contended; dev defaults pass the
assert byte-identically while prod overrides fail it by name; collector unit-tested
against 8 resolver shapes.

Closes the LAST scaffold-only safety-critical requirement. The operator has attested DR
works (Velero -> Proxmox versitygw S3, restore demonstrated), but the L3 test carried the
right tag and layer label over a 5-line TODO body — so coverage counted it and reported
"0 safety-critical gaps" while the suite asserted nothing. That was test debt, not
capability debt. This makes the suite assert what the operator already demonstrated.
Three steps:
1. assert-backup-target-is-off-cluster (read-only): BSL must be phase Available (Velero
itself reached the store), s3Url host is not localhost/*.svc/*.cluster.local, and the
resolved IPv4 is none of — loopback, any Node Internal/ExternalIP, any Service
ClusterIP, any Pod IP, inside any node podCIDR, inside any ServiceCIDR. A BSL that
exists but never reaches Available FAILS (a live DR defect), it does not skip.
2. assert-backups-are-scheduled: R-STATE-03 says SCHEDULED off-cluster backups — Velero
+ BSL but zero Schedule in phase Enabled is a fail.
3. The drill: seed a nanosecond-unique canary onto a longhorn PVC in its own scratch
namespace; Backup to Completed; assert a PodVolumeBackup for that volume is Completed
WITH a non-empty status.snapshotID (the kopia snapshot of volume DATA reached the
remote repo, not just resource JSON); ANNIHILATE the source (delete ns, poll until
gone, force-delete a lingering PV, FAIL if the original PV survived — a survivor makes
the restore prove nothing); Restore with namespaceMapping into a clean namespace;
assert the restored PVC bound a DIFFERENT PV and that the canary bytes are identical.
Off-cluster proof = endpoint outside every cluster address + BSL Available + kopia
snapshotID present + every in-cluster copy destroyed + restore landing on a new PV. The
bytes could only have come from outside.
Skips GREEN on: no longhorn SC, Velero API absent, no BSL, Velero/node-agent not ready —
all three steps re-derive the same gates so it can never half-run. An RBAC denial is
deliberately NOT a skip: it fails loudly as a harness defect. Teardown is a step-level
`finally` that ALWAYS runs — deletes the Restore, issues a DeleteBackupRequest so objects
leave the bucket (2h ttl as backstop), deletes both scratch namespaces by name and by
label, releases leftover PVs whose claimRef is one of its own. Everything it destroys is
something it created.
conformance/incluster/rbac.yaml: authored the R-STATE-03 grants (velero.io backups/
restores/deletebackuprequests create+delete+read; BSL/schedules/podvolume* read-only;
persistentvolumes get/list/DELETE — the off-cluster proof requires destroying the PV).
Also two pre-existing gaps other tests already depended on: storageclasses get/list (the
skip gate of five tests) and apps deployments/daemonsets read. No write verbs on platform
controllers.
NOT ASSERTED, stated in the file header rather than implied: off-HOST (on dev the nodes
are VMs on the same Proxmox host as the S3 target, so this does not survive hypervisor
loss); no direct S3 client read (that would hand a privileged test identity the backup
credential for weaker evidence); real service data (Nextcloud/Gitea/CNPG drills stay
operator exercises); bare-metal rebuild DR; encryption-at-rest; retention/GC.
status: scaffold-only 5 -> 4; safety-critical w/o executable L3 1 -> 0 (of 6); executable
35 -> 36. coverage unchanged at 40/51 (correct — coverage only asks whether a tagged test
exists). PROVEN stayed 0 / not-derivable: it did NOT flip to proven just because the body
is non-empty.
AUTHORED, NEVER EXECUTED — carries a conformance.home.k3s/never-executed annotation. No
cluster access from this workstation. To convert authored -> proven the operator must, IN
A MAINTENANCE WINDOW (it deletes namespaces and PVs and writes/deletes bucket objects):
apply the updated rbac.yaml, run `./conformance/run.sh --requirements R-STATE-03 --layer
l3`, confirm the log shows DR_RESTORED_FROM_OFF_CLUSTER_BACKUP_OK and NOT
DR_RESTORE_SKIPPED_OK (green but proves nothing), confirm no leaked *-dr-src/*-dr-dst
namespaces or orphan PVs or *-dr-backup objects, and record the green run.

roles/k3s_server, roles/cilium and every node-host playbook hardcoded the dev group
names k3s_primary/k3s_secondary/k3s_servers, so the prod inventory groups could not be
selected at all. That broke the R-ENV-02 promise that prod reuses the SAME roles, and
blocked PROD-PROVISIONING.md §6 outright.
TWO KNOBS, deliberately separate — Ansible templates a play's `hosts:` BEFORE any host
context exists, so group_vars is unreadable there, while roles run WITH host context:
* which hosts a play RUNS ON — k3s_hosts, k3s_primary_hosts/k3s_secondary_hosts
(k3s.yml's split), vpn_egress_gateway_hosts; each `| default(<dev group>)`, set by -e
only. Follows node-health.yml's established `<name>_hosts | default(dev)` pattern.
* which group a ROLE means by "my primary"/"my servers" — k3s_primary_group,
k3s_servers_group in group_vars/all.yml (dev), overridden in group_vars/k3s_prod.
Follows the k3s_api_host convention already in this repo. No per-run flag.
DEV IS UNCHANGED — the key evidence. --list-hosts/--list-tasks/--syntax-check captured
for all 9 playbooks at HEAD and after: sorted host lists IDENTICAL for all 9, same
primary/secondary split, same 6-play site.yml. (Raw --list-hosts PRINT ORDER varies run
to run; proven to be Ansible's own set ordering by running UNMODIFIED HEAD cilium.yml
four times -> 3,1,2 / 1,3,2 / 1,2,3 / 1,2,3. Hence sorted comparison.) --list-tasks
differs in exactly two files, only by added TAGS annotations and one new assert; no task
reordered, renamed or removed. Var resolution verified per environment with -c local:
dev -> k3s_primary/192.168.1.50/sans .50,.49,127.0.0.1,.51,.52; prod ->
k3s_prod_primary/192.168.2.10/vip .9/sans .10,.9,127.0.0.1,.11,.12.
BREAKS THE SMARTMONTOOLS CIRCULAR DEPENDENCY. node_baseline tasks are now tagged
packages/system/disks, so the package install can run alone:
ansible-playbook playbooks/node-baseline.yml -e k3s_hosts=k3s_prod --tags packages
Skipping is the guard — no disks-tagged task is selected, so the
BLOCKED-pending-disk-decision paths are never templated, let alone passed to mkfs.
Belt-and-braces, a new disks-tagged assert fires first in a FULL run and names §2
explicitly instead of failing obscurely at mkfs. `tags: never` was deliberately NOT used
(it would change the default run).
FOOTGUN FOUND AND FIXED: roles/cilium, cluster_verify and flux_bootstrap all hardcoded
.cache/dev.kubeconfig — the exact file infra/devcontainer/dev.sh exports as $KUBECONFIG.
Once prod became targetable, a prod cilium/verify run would have SILENTLY OVERWRITTEN it,
leaving the operator's kubectl quietly answering from PROD. Now cluster_kubeconfig_name
(dev.kubeconfig -> prod.kubeconfig). Dev path byte-identical.
KNOWN, DOCUMENTED, NOT FIXED HERE: flux-bootstrap.yml retargets but roles/flux_bootstrap
shells out to bootstrap/flux/bootstrap.sh with a hardcoded --path=clusters/dev — a
bootstrap/ subtree change, not a target-group change (§6, cross-referenced to §7).
vpn.egress.gateway.yml is parameterised but prod has no egress group yet and would need
its own vaulted PIA credentials. --check against prod is still impossible until the prod
vault exists — even the packages-only run needs it.
Nothing was run against the dev cluster: --list-hosts/--list-tasks/--syntax-check, plus
debug/assert with -c local, only.

Re-authors the fix stranded on origin/fix/act-runner-dind-readiness (242951a), which
applied cleanly but had never been merged.
The act_runner startup waited only for the dind TLS CERT FILE (/certs/client/ca.pem),
but dockerd writes the certs before it begins accepting TLS connections on :2376. A
runner proceeding on the file alone still hard-exits with "cannot ping the docker daemon
at tcp://localhost:2376" — observed crashlooping 11 times in ~8 minutes on a fresh pod
after a node bounce. Adds a second bounded wait (nc -z -w1 127.0.0.1 2376, 60s cap)
mirroring the existing cert-file loop, so the runner starts only once the daemon
actually answers. busybox nc in the Alpine-based gitea/act_runner:0.2.11 supports -z/-w.
This Deployment is the ENFORCED MERGE GATE for the whole repo, so it ships alone.
A REPORTED "latent envsubst bug" in this file was INVESTIGATED AND DISPROVEN. The claim
was that Flux envsubst expands bare `$i`, making the existing `[ "$i" -ge 60 ]` bound a
silent no-op. Running the real `flux envsubst` (v2.4.0) shows bare `$i` is NOT
substituted — even with i set in the environment, `$i` passes through literally while
`${i}` expands. This matches the repo's own contract in clusters/base/apps-vms.yaml,
which was itself written after empirical probing: "`$VAR` -> left alone by envsubst =>
bare shell vars need NO escaping." The existing 60s bound was always real. NO escaping
was applied: `$${i}` would be an ACTIVE REGRESSION, correct only on the envsubst path —
on a plain `kustomize build`/`kubectl apply -k`, sh reads `$$` as its own PID and the
bound compares garbage against 60. Bare is correct on both paths. A comment now records
the real contract so nobody "fixes" the bare form into escaping.
NEAR MISS worth recording: the first draft of that comment spelled the dangerous forms
out literally, and `flux envsubst` HARD-FAILED on it — "unable to parse variable name".
Flux's envsubst runs over the entire manifest INCLUDING YAML COMMENTS, so a braced name
containing punctuation is a fatal parse error that would have failed the whole
apps-wave-1 Kustomization — breaking every merge in the repo. From a comment. The
shipped comment names the forms in words; the file now contains no braced-dollar
sequence at all.
Verified without a cluster: flux envsubst over the file is byte-identical (exit 0, and
--strict 0); post-envsubst YAML parses with containers unchanged; `sh -n` clean; a
dry-run with a stubbed failing nc fires the stage-2 bound and exits 1; render==golden
green (gitea-actions.yaml is an EXTRA_UNITS entry — render.py places the filename into a
wave and never emits its bytes, so it is not among the 10 compared goldens).
Follow-up documented in-file, deliberately NOT done here: convert dind to an
initContainers sidecar (restartPolicy: Always) with a startupProbe that execs `docker
info` over TLS — NOT a bare tcpSocket probe, which would reopen the same "port open but
certs not ready" gap stage 1 closes — periodSeconds 1 / failureThreshold 60 to preserve
the cap, after which runner drops its command: override. k3s v1.36 has GA sidecars, so
this is the correct long-term shape; it ships separately because a failure in the merge

Unblocks the enforced Gitea gate, which correctly BLOCKED this branch on
['R-SEC-01','R-SEC-02','R-TEST-06'] being touched but uncovered. Tests were authored;
the coverage rule was NOT narrowed.
=== THE FALSE GREEN (root cause) ===
`make -C ci gate` locally reported PASS having checked NOTHING. resolve_base() validated
nothing, and EVERY way of failing to find a base degraded silently to an empty touched
set + exit 0: an `HEAD~1` last resort, a two-dot diff fallback masking a failing
three-dot diff, and no check that HEAD is even AHEAD of the base. Run while sitting on
`main` (main == origin/main), `origin/main...HEAD` is empty -> "no changed files vs
base" -> the empty set means run.sh is invoked with NO --requirements -> coverage.py's
--require gate never runs at all. Green by vacuum.
Now: candidates are BASE_REF > GITHUB_BASE_REF > origin/main > main, each verified to
resolve. HEAD~1 and the two-dot fallback are gone. Unresolvable base / no merge base /
failed diff / HEAD-not-ahead -> loud banner, EMPTY stdout, exit 3, and a machine-readable
reason (on-base | no-base | diff-failed). gate.sh turns exit 3 into an UNDECIDED
decision: `on-base` -> "NOT APPLICABLE — no branch under gate" (exit 0 so push-to-main
runs don't break, but it never reads as PASS); `no-base`/`diff-failed` -> BLOCKED. It
also now prints the diff base it used. A stale local main warns (widens, never falsely
greens). Also fixed `make -C ci test`, which was SWALLOWING failing suites.
Regression: ci/tests/touched-requirements-base.test.sh — 31 assertions over 8
throwaway-repo scenarios including the exact false-green case, an already-merged branch,
no base ref, a single-commit repo, bogus BASE_REF, a shallow GITHUB_BASE_REF, and
origin/main-preferred-over-stale-main.
=== NEW L0 STATIC LAYER (conformance/tests/l0-static/) ===
Where docs/14 actually puts these invariants. Each check.sh really executes offline via
`run.sh --layer l0` and is wired into ci/l0.sh, so it runs on every PR. No scaffolds.
R-SEC-01 no-plaintext-secrets (165 assertions / 445 tracked files): .sops.yaml holds only
PUBLIC age recipients; every committed Secret is SOPS-wrapped with a mac and ENC[...]
values; ansible vault.yml files are $ANSIBLE_VAULT; no secret-valued ansible key carries
a literal outside a vault; no PEM key / age secret key / kubeconfig client-key-data is
tracked; Flux declares sops decryption; the disallow-plaintext-secrets policy Enforces
and has a proving `result: fail` row. Exemptions are SELF-POLICING, not path allowlists —
a .example must be referenced by no kustomization and hold only placeholders, and the
Kyverno fixture is exempt ONLY while a test asserts the policy rejects it. Proven against
7 injected violations, including deleting the negative row and weakening Enforce->Audit.
R-SEC-02 least-privilege-rbac (41 assertions): no wildcard apiGroup/resource/verb and no
escalate|bind|impersonate in any in-repo Role/ClusterRole; no ServiceAccount bound to
cluster-admin or a wildcard role; the conformance runner's own test identity is scoped
and holds no rights over RBAC objects; the default-deny/host-namespace/egress-class
policies Enforce and each carry a negative row. Proven against 6 injected violations.
R-TEST-06 spec-immutability-enforced (16 assertions): drives the REAL
ci/spec-immutability.sh against HERMETIC throwaway spec repos and asserts its exit code
in every state — clean-at-pin 0, edits under docs/ or decisions/ 1, untracked addition 1,
unadopted drift 1, explicit pin bump 0, ABSENT spec repo 3 (honest skip, never green),
unpinned SPEC_PIN 1 — plus that gate.sh sets BLOCK=1 on its failure, so the mechanism is
load-bearing. The real spec repo is never written to.
Each check documents what it does NOT cover (runtime decryption, git history, runtime
least-privilege, branch protection) rather than overclaiming. status.py now reads
check.sh too, so a placeholder L0 body still outranks an `executable: true` annotation.
Coverage 37/51 -> 40/51 (11 gaps); executable tests 32 -> 35; scaffold-only stays 5 —
no sixth scaffold was added.

Operator ask: implement the roles needed to check prod node hardware health, and run
them to find out our state. This is that role; the run's findings are below.
roles/node_health is a read-only sibling to cluster_verify (cluster health vs hardware
health), styled after node_baseline. One unprivileged collector script does the work in
a single SSH round trip — reading /sys/class/dmi, thermal + hwmon, EDAC, cpufreq +
thermal_throttle, /proc/pressure, /sys/block incl. SCSI ioerr/iotmo counters, lsblk,
lscpu, mounts + statvfs, per-NIC stats, resolv.conf.
THE DESIGN POINT: an unreadable field is emitted as null WITH A RECORDED REASON, never
as zero. The summary ends with a "NOT READ (and why) — these are UNKNOWNS, not passes"
section. A fake zero on a reallocated-sector count is exactly the kind of false green
this project refuses. 22 checks report PASS/WARN/FAIL/SKIP/INFO; every SKIP says why.
Report-only by default; thresholds live in defaults/main.yml.
Portable across bare metal AND VMs — validated against k3s-prod-1 (bare metal, no root)
and k3s-dev-1 (VM, root). VM-absent things (SMART on virtio, coretemp, EDAC) skip
cleanly, and iSCSI/Longhorn volumes are split out of the physical-disk set so a live
replica is never mistaken for a spare device.
playbooks/node-health.yml takes its target group as a variable (-e node_health_hosts=
k3s_prod), deliberately unlike the other playbooks that hardcode k3s_servers — see the
group-name gap already flagged in hosts.ini.
Two become facts found the hard way and documented in the role: a group_vars
`ansible_become: true` OUTRANKS `become: false` as a play/task keyword, so unprivileged
tasks must override the variable; and `failed_when: false` does NOT catch "Missing sudo
password" — only `ignore_errors` does.
FIRST RUN, k3s-prod-1, 2026-08-31: 0 FAIL · 3 WARN · 12 PASS · 3 SKIP · 4 INFO.
Box is healthy, cool and unstressed: i7-9700T 8C/8T, VT-x + /dev/kvm (KubeVirt OK), zero
throttle events, hottest sensor 33C, PSI 0.00 across the board, 31.1 GiB RAM, eno1 up at
1000 Mb/s, BIOS R21 02.26.00, no reboot pending.
DRIVE HEALTH IS STILL UNKNOWN — the headline. SMART did not run, blocked TWICE over: no
vaulted ansible_become_password for prod, AND smartmontools is not on the node at all
(node_baseline has never run there). Power-on hours, wear, reallocated/pending sectors
and drive temperature all remain unmeasured on a ~2011 consumer SSD.
WARNs: kernel ioerr_cnt=6 on sda (read cautiously — four freshly attached iSCSI disks on
dev each showed a flat 7, suggesting a fixed per-device discovery cost, not media
trouble; attribution needs dmesg/root); 0.95 GiB swap still active (node_baseline does
the swapoff); one IPv4 resolver only (the other two upstreams are IPv6 Google), which
refines rather than resolves the DNS-SPOF finding.
ESCALATION — ECC status is UNKNOWABLE on this hardware: /sys/devices/system/edac/mc
exists but no controller is bound. Non-ECC consumer RAM. Silent memory corruption on a
prod node would be undetectable. Recorded as a SKIP with reason, not a pass.

Operator directive: conformance and gates are enforced at the Gitea runner / CI-CD
level — use it. The authority on mergeability is the Actions run, not a local
`make -C ci gate`; local runs are a fast pre-check only.
Proven immediately on this branch. Same commit (a1fb31a):
local -> "no changed files vs base; empty touched-requirement set" -> MERGE GATE: PASS
CI -> 17 touched requirements -> REQUIRE: FAILED, uncovered
['R-SEC-01','R-SEC-02','R-TEST-06'] -> MERGE GATE: BLOCKED
The local run resolved an empty diff base, checked nothing, and reported green. A local
false green is this project's most dangerous failure mode — it hid real coverage debt.
Fix in progress so local agrees with CI or announces loudly that it cannot determine a
base; an honest noisy skip beats a quiet false pass (ci/README.md exit-code contract).
The gate was RIGHT: we authored a vaulted-secret flow (R-SEC-01) and status tooling
reasoning about spec immutability (R-TEST-06) while those requirements had NO covering
test. Tests are being authored; the rule is NOT being narrowed.
Also records how to read CI from a workstation — the API paths are non-obvious on this
Gitea version (actions/runs/<run>/jobs 404s; use actions/tasks + actions/jobs/<id>/logs,
noting the task-id -> job-id offset).
OPERATOR ATTESTATIONS: DR is proven (Velero -> Proxmox server, restore demonstrated) and
dev-cluster resilience is proven (slow only because Longhorn is on HDD; etcd is on its
dedicated SSD). Both recorded as fact. Kept distinct from automated proof: the status
report's R-STATE-03 finding is TEST debt, not capability debt — the system does the
thing, the suite does not yet assert it. The attestation does not close the requirement
and the gate must not be softened to make it appear closed.

PROD-PROVISIONING.md §4 now carries the full operator-decided address table (nodes
.10/.11/.12, control-plane VIP .9, ingress Gateway VIP .20, Cilium LB pool .20-.30) with
the two invariants that make it safe: the control-plane VIP sits outside the LB pool so
kube-vip and LB-IPAM cannot contend, and GATEWAY_VIP is the FIRST address of the pool
because the shared Gateway pins nothing and LB-IPAM hands it the first free address.
§5 no longer tells the operator to hand-install smartmontools — package installation is
the node_baseline role's job (operator ruling). §0 gains the node 2/3 addresses.

Operator ruling: "I care about the state of the repository and what the status of each
spec is based on that state" — not a hand-maintained task board. This is that report.
conformance/lib/status.py (stdlib-only, --selftest) sits beside lib/coverage.py and
IMPORTS it rather than forking the registry/test parsers. Driven by a new
`conformance/run.sh --status`; artifacts land in _artifacts/status/ alongside coverage
and are git-ignored by the existing convention. Exit codes follow ci/lib.sh (0/1/3);
--strict-coverage also applies the status hygiene gate.
Signals derived per requirement: is there an implementing artifact; is it RECONCILED
(walk resources: from clusters/dev, expand each Flux Kustomization's spec.path, recurse
— so a commented-out resource correctly does not count); is there a tagged test and is
its body executable or a TODO scaffold (TODO markers OUTRANK an executable: "true"
annotation — ambiguity never upgrades a row).
DELIBERATELY NOT DERIVED, and reported as such rather than defaulting to green:
proof-of-pass (nothing tracked in git records a run result — _artifacts/ and results/
are git-ignored) and cluster liveness. "Reconciled" means Flux WOULD apply it, not that
it is healthy. PROVEN is reported as "not derivable" for all 51.
WHAT IT SHOWS THAT coverage.md DOES NOT. Coverage reports 37/51 covered, 0
safety-critical gaps. Three of those claims do not survive repo state:
1. 5 of the 37 "covered" requirements have only a TODO-body scaffold (R-STATE-03,
R-OBS-02, R-OBS-04, R-GITOPS-03, R-GITOPS-02). Coverage counts a tagged file; it
never looks inside it.
2. R-STATE-03 is SAFETY-CRITICAL and its L3 fault test asserts nothing. Coverage reports
"0 safety-critical gaps" only because dr-restore/chainsaw-test.yaml exists and carries
an L3 label. --strict now fails on this.
3. R-UPD-01/02/03 are NOT reconciled: platform/image-automation/ is commented out of
platform/kustomization.yaml. Coverage shows them covered with executable L3 tests,
which reads as delivered; automated updates are actually 0/3 wired+testable.
Headline: 51 requirements | reconciled 20 (+12 partial) | executable test 32 |
wired+testable 22 (+8 partial) | scaffold-only 5 | PROVEN 0 (not derivable).
Also surfaces 18 requirements with no reconciled manifest citing their R-ID — listed as
a traceability gap (R-TEST-04) rather than guessed either way. Annotating those manifests
makes the report self-correct, so it acts as a forcing function instead of another
hand-maintained map.

Prod inventory scaffolding for the three bare-metal nodes, and the become posture the
operator ruled for production.
BECOME: prod does NOT get dev's NOPASSWD sudo. Prod keeps a real sudo boundary and
supplies the password to Ansible as an ansible-vault-encrypted `ansible_become_password`
in inventory/group_vars/k3s_prod/vault.yml, mirroring the existing hypervisor and
proxmox_hosts groups. The decrypting passphrase stays outside the repo
(~/.config/home-k3s/ansible-vault-pass), so plays still run unattended with no plaintext
secret in git. Committed here: README.md + vault.yml.example only — the operator creates
the encrypted vault (`ansible-vault create`), as with every other vaulted group.
PACKAGES BELONG IN THE ROLE (operator ruling): smartmontools is now declared in
node_baseline_packages, not hand-installed on a node. Drive health tooling is a
permanent part of a bare-metal node's baseline — dev nodes are VMs and never needed it.
Same click-ops-never principle as the rest of the repo.
ADDRESSING: nodes .10/.11/.12, reached DIRECTLY on the LAN (no pfSense NAT hop, unlike
dev's 192.168.2.102:225x mapping), so ansible_host is the real node IP. kube-vip
control-plane VIP is 192.168.2.9 — deliberately BELOW the nodes and OUTSIDE the Cilium
LB pool (.20-.30) so kube-vip and LB-IPAM can never contend for an address. The ingress
Gateway VIP (.20) and the LB pool are Flux/cluster-vars concerns and deliberately do
not appear in Ansible.
BLOCKED-BY-DESIGN: node_baseline_longhorn_device / node_baseline_etcd_device are present
but set to an obviously invalid /dev/BLOCKED-... path pending the operator's disk-layout
decision (node 1 is a single SATA SSD; the role's /dev/vdb,/dev/vdc defaults are virtio
names that do not exist on bare metal). Leaving them unset would silently fall back to
those equally-nonexistent defaults — a confusing failure that looks like a wiring bug.
This fails just as hard and says exactly why.
KNOWN FOLLOW-UP: roles/k3s_server and every node-host playbook hardcode the literal
group names k3s_primary/k3s_secondary/k3s_servers, so the k3s_prod_* groups are not
selected by them as-is. Harmless now (nothing can accidentally run against prod) but the
"same roles, unchanged" reuse R-ENV-02 promises needs the target group parameterized
before §6 of PROD-PROVISIONING.md can execute. Documented in hosts.ini and both READMEs.

R-ENV-02 promises dev and prod differ ONLY by scoped cluster-vars overrides. In fact
dev LAN addresses were hardcoded into base manifests, so clusters/prod would have come
up ANNOUNCING DEV ADDRESSES (192.168.1.x) on the prod LAN (192.168.2.x).
New cluster-vars knobs (base default = dev literal, per the file's existing convention):
K3S_API_HOST platform/cilium/helmrelease.yaml (+ the values.yaml mirror)
CILIUM_LB_POOL_START platform-config/cilium/l2-ip-pool.yaml
CILIUM_LB_POOL_STOP "
UNIFI_L4_VIP apps/vms/unifi/50-service-l4.yaml
CRAFTY_L4_VIP platform/crafty/service-l4.yaml
S3_BACKUP_ENDPOINT platform/keycloak/postgres-cluster.yaml, apps/wave-0/{nextcloud,
semaphore}-db.yaml, and platform/velero/helmrelease.yaml
Also fixes GATEWAY_VIP's base default, which was still the RETIRED libvirt address
10.73.0.240, and adds the GATEWAY_VIP patch that clusters/prod was missing entirely.
clusters/base/apps-vms.yaml gains postBuild.substituteFrom (it was the one consuming
Kustomization without it, so a ${TOKEN} there would have shipped as a literal string).
The envsubst contract is documented there: ${VAR} substitutes and escapes as $${VAR};
$VAR and $(cmd) are left alone; ${ARR[0]} hard-errors. The three UOS_URL expansions in
the unifi cloud-init are escaped accordingly.
PROD ADDRESS PLAN (operator, 2026-08-31):
nodes .10/.11/.12 · control-plane VIP .9 (Ansible-side) · GATEWAY_VIP .20
Cilium LB pool .20-.30
CONTAINMENT INVARIANT, now documented at the pool and in the prod overlay: GATEWAY_VIP
MUST equal CILIUM_LB_POOL_START. The shared Gateway pins no address, so Cilium LB-IPAM
gives it the first free address of a matching pool block. An initial prod proposal put
.20 outside a .21-.30 pool; the Gateway would have come up on .21 while split-horizon
coredns-custom kept answering *.home.keithjackson.dev with .20 — an address nothing
announces — blackholing in-cluster OIDC hairpin traffic while reporting healthy. The
pool was widened to .20-.30. The control-plane VIP (.9) stays outside the pool so
kube-vip and LB-IPAM can never contend.
Values prod still cannot know stay INVALID `TBD-PROD-*` placeholders on purpose: base
defaults are dev values, so an omitted patch means prod silently inherits a dev address
— far worse than a loud failed apply.
DEV IS BYTE-IDENTICAL. Verified by kustomize build over 13 paths before/after, then
flux envsubst with the dev cluster-vars values applied to both sides: zero drift. The
only deltas are the intended additive keys in the overlay ConfigMap itself. No
unresolved ${TOKEN} survives. render-golden green (10 goldens); yamllint clean.

Two operator corrections:
1. PROD DOES NOT GET NOPASSWD SUDO. My initial checklist recommended mirroring dev's
passwordless sudo onto prod — rejected, correctly. Dev's NOPASSWD is a convenience
that must not propagate to production. Prod instead keeps a real sudo boundary and
drives Ansible `become` with an ansible-vault-encrypted `ansible_become_password` in
inventory/group_vars/k3s_prod/vault.yml, mirroring the EXISTING hypervisor and
proxmox_hosts groups. The decrypting passphrase stays outside the repo at
~/.config/home-k3s/ansible-vault-pass (ansible.cfg :: vault_password_file), so plays
still run unattended with no plaintext secret in git.
2. THE TASK BOARD IS NOT THE STATUS SURFACE — THE REPOSITORY IS. Operator ruling closes
the escalation raised in the previous commit. Requirement/spec status is to be DERIVED
from repo state (what is authored, reconciled, and covered by a green requirement-tagged
test), not from a hand-maintained board. The spec board is left as a historical seed;
no agent edits it and no SPEC_PIN churn is spent on it. ci/spec-immutability.sh keeps
its full strictness — no path exception was added, since weakening an R-TEST-06 gate
for a bookkeeping file would be a defect, not a fix. A repo-derived spec status report
becomes the artifact of record alongside the coverage report and this log.

The operator added the first production node (k3s-prod-1, 192.168.2.10 — HP EliteDesk
800 G5 Mini, i7-9700T/31GiB, Debian 13, VT-x + /dev/kvm) and opened roadmap Phase 7 for
PREP WORK ONLY: no k3s install until the R-ENV-02 blockers close and the gate is green.
Records the Phase-7 entry-gate position honestly: the operator has declared hardware
ready, but "Phases 1-6 proven in dev/test" is NOT met (37/51 conformance; R-ENV-01/02/03
themselves uncovered). Proceeding is an explicit, accepted risk — not an oversight.
Adds infra/PROD-PROVISIONING.md (T-7.1, design-only): firmware/BIOS, disk layout, OS,
network, access, Ansible reuse, repo blockers, build sequence, Phase-7 exit criteria.
Key findings recorded in DECISIONS-LOG:
- R-ENV-02 is violated in the base — dev LAN addresses hardcoded into base manifests
(cilium k8sServiceHost, the Cilium LB pool, crafty/UniFi LB IPs, 3 S3 backup
endpoints). Prod is on 192.168.2.x, so prod would build WRONG today.
- clusters/prod never sets GATEWAY_VIP -> would inherit the base default 10.73.0.240,
an address on the RETIRED libvirt network.
- No NOPASSWD sudo on the prod node -> all Ansible fails at its first become.
- node_baseline device defaults are virtio (/dev/vdb,vdc) and absent on bare metal.
- ESCALATION: agents/task-board.md is structurally unmaintainable — AGENTS.md designates
it the one agent-editable surface, but ci/spec-immutability.sh fails the gate on ANY
spec-repo dirt with no path exception. Explains the all-todo board after six phases.
NOT worked around: exempting it would weaken an R-TEST-06 gate. Operator decision.
Operator decisions: Phase 7 open (prep only); wait for all 3 nodes before cluster-init;
check drive health before choosing the single-SSD disk layout.

The kustomization pulled two REMOTE github bases (?ref=v8.2.0) that Flux's kustomize-controller
git-fetched on every reconcile; those fetches intermittently exceeded the 27s timeout ->
'kustomize build failed' BuildFailed events -> the whole platform tier stalled whenever GitHub was
slow. Vendored the exact v8.2.0 output to local crds.yaml + snapshot-controller.yaml (built with
kubectl kustomize; images transformer still re-pins the controller to v8.2.0), so the build is now
offline + deterministic. No change to what's deployed. platform/kubevirt has the same latent pattern.

HAND-OFF 2 (L2/L3 conformance wiring) — DEFERRED with a concrete plan, per the
hand-off's escape hatch (too risky to wire live cluster access from CI autonomously;
do NOT hand CI a broad kubeconfig).
The intended seam (in-cluster Chainsaw Job under its own scoped SA; CI holds only a
narrow trigger credential) is mostly scaffolded but not safe to finish autonomously:
- ci/conformance.sh still runs run.sh locally rather than triggering the in-cluster Job.
- conformance/incluster/chainsaw-job.yaml has no repo-clone init-container and the stock
chainsaw image lacks bash/python3/kubectl/git that run.sh needs.
- No trigger SA/RBAC/credential exists, and the core blocker is a privilege-escalation
design question: any `create jobs` credential in the conformance namespace can create a
Job running as the privileged conformance-runner SA. This needs an admission constraint
(recommended: narrow trigger SA + a Kyverno policy pinning the admissible Job shape), or
a GitOps-native zero-credential trigger — an operator decision.
- conformance/incluster/ isn't wired into Flux; Gitea vars/secrets aren't provisioned.
docs/plans/l2-l3-conformance-ci-wiring.md captures current state, the security analysis,
the functional gaps, a file-by-file step sequence, validation/rollback, and the open
decisions. gate.yml's conformance placeholder now points to it (still if:false, honest).

HAND-OFF 1 (make -C ci gate parity).
touched-requirements.sh gained a third scoping rule: after stripping the diff
marker, whole-line YAML/shell `#` comments are dropped BEFORE the R-ID grep. A
requirement cited only in a code-file comment is prose (a REFERENCE), not a
declaration -- the same logic rule 2 already applies to `*.md`. This unblocks the
self-referential trap where editing gate.yml's header (which cites R-TEST-06, a
known-uncovered ID enforced by the spec-immutability STAGE, not a Chainsaw test)
re-attributed R-TEST-06 so the coverage `--require` check false-blocked the merge.
Conservative: only whole-line comments are dropped; an R-ID on a real code/spec
line is still detected, and authoritative declarations never live in a bare comment.
gate.yml now invokes the aggregate `make -C ci gate` (ci/gate.sh) instead of the
individual stage scripts, so CI runs byte-for-byte the same gate a human runs in the
devcontainer (R-TEST-02) and applies the R-TEST-03 decision. A BLOCKED gate exits
non-zero and fails the job. The cluster-gated L2/L3 stage SKIPS honestly (no
CLUSTER_AVAILABLE). spec-immutability is retained as an explicit early UI step.
Adds ci/tests/touched-requirements.test.sh (+ `make -C ci test`) asserting rule 3:
comment-only R-IDs (added or removed) are not attributed while real-line R-IDs are.
ci/lib.sh REPO_ROOT is now env-overridable so tests can run the real script against a
throwaway git repo (default unchanged).

Roll the verified Option-B per-app oauth2-proxy sidecar out to the remaining
four forward-auth apps after the pihole canary was confirmed fail-closed
(unauthenticated -> 302 to Keycloak, pod 2/2, clean sidecar OIDC discovery).
Each app's Gateway route now terminates at its oauth2-proxy sidecar (:4180,
--allowed-group=media-users, --upstream=http://127.0.0.1:<uiport>); the
gateway-ingress CiliumNetworkPolicy allows the Gateway to reach ONLY :4180, so
the bare UI is never served un-authenticated (fail-closed; R-IDP-02/06). The
apps' own app/API ports stay in-Service for EAST-WEST callers (arr ->
qbittorrent:8080 / jackett:9117) via the existing reciprocal-ingress allows.
- keycloak: confidential jackett/qbittorrent/radarr/sonarr clients (realm-import
+ realm-clients mirror), provisioned live via kcadm (groups membership mapper).
- secrets: four SOPS/age <app>-oauth2-proxy-credentials, wired into apps/wave-0
and apps/wave-1 by the renderer's sidecar-creds wave rule.
- ci: remove the temporary canary deferral (all five goldens now reproduce).

Close the un-gated-UI security finding for forward-auth apps (R-IDP-02) by
rendering the Option-B per-app oauth2-proxy reverse-proxy sidecar that crafty
proves working. catalog/render.py now emits, for any forward-auth app with an
exposed UI: the oauth2-proxy sidecar (upstream http://127.0.0.1:<uiport>,
:4180, --allowed-group per auth.group), an authproxy :4180 Service port, an
HTTPRoute backendRef -> :4180, and a gateway-ingress CiliumNetworkPolicy that
allows the Gateway to reach ONLY :4180 (fail-closed: the bare UI is never
served un-authenticated). oidc/native/none apps render byte-identical.
This is the CANARY: only pihole's golden carries the sidecar and is verified
fail-closed in-cluster first. jackett/qbittorrent/radarr/sonarr are deferred to
the rollout commit (temporarily listed in ci/render-golden.sh) so their UIs
keep serving exactly as today until their clients+secrets land.

- secret: SOPS/age pihole-oauth2-proxy-credentials (client-id/secret/cookie),
wired into apps/wave-0 via the renderer's new sidecar-creds wave rule.
- L1 render goldens regenerated for the sidecar (forward-auth fixtures).

Investigation + phased implementation plan to move the churn-heavy,
latency-sensitive Longhorn volumes (Prometheus, the CNPG Postgres DBs,
Loki, gitea) off the slow/failing HDD 'Storage' pool onto a tagged
SSD-backed Longhorn disk on local-zfs, ending the reboot rebuild storm.
Key finding: the recorded 'SSD does not fit Longhorn' blocker was based
on the 384 GiB provisioned figure; actual working set is ~79 GB
cluster-wide (~26 GB/node) since all bulk media is on NFS, not Longhorn.
Hot tier is ~51 GB actual / 114 GiB provisioned and fits the ~323 GiB
SSD AVAIL with headroom. Read-only investigation; no live storage
touched.

The three KubeVirt VM conformance tests (vm-lifecycle, vm-default-deny,
vm-data-survival) carried comments asserting the ALPHA `ImageVolume` feature
gate is DISABLED "on this k3s v1.31 cluster" and that the apiserver therefore
prunes the container-disk `image` volume, breaking the containerDisk boot path.
The cluster was upgraded v1.31 -> v1.36.4. Revalidated the gate live:
- kubernetes_feature_enabled{name="ImageVolume"} = 1 (enabled by default;
stage="" — no longer ALPHA)
- a server-side `kubectl apply --dry-run=server` of a Pod with an `image`
volume RETAINS the volume + mount instead of pruning them.
So the old premise is stale: containerDisk roots would boot on 1.36.4. The
tests never asserted the gate state and never used containerDisk — they boot
from CDI DataVolume roots, which remains the correct choice because it is the
spec-required, rebuild-surviving disk model (docs/06, R-STATE-01); an ephemeral
containerDisk could never satisfy data-survival. Test logic is therefore
unchanged; only the explanatory comments are corrected (v1.31 -> v1.36.4, and
the "containerDisk is broken here" rationale marked stale with the live
evidence).
Merge gate: PASS (lint, l0, render-golden, l1 green).

Research + implementation plan (no live change) on whether Cilium 1.20.1's
native Gateway API ExternalAuth filter (GEP-1494) can replace the un-wired
forward-auth CEC template and Crafty's oauth2-proxy sidecar.
Verdict: DEFER. The filter exists in 1.20.1 code (shipped 1.20.0, PR #45739) but
is EXPERIMENTAL-channel Gateway API; the cluster runs the standard-channel CRDs
(verified: HTTPRoute filters[].type enum lacks ExternalAuth), so it is not even
installable today. Also: fail-open bug (#47178, fixed#47265) in a brand-new
security filter, no 1.20 docs, and the ext_authz hop would hit the same
enforce_policy_on_l7lb hairpin re-evaluation just fixed for Keycloak (68690e5).
Plan is phased/reversible (pihole canary first) and keeps the working sidecar.
Resolves the DECISIONS-LOG open item on ext_authz workaround relevance under 1.20.1.

Steady-state CPU PSI 15-23% + 15-min load 5.6-8.0 on 6 cores (run queue at/over core count) left no
headroom for bursty workloads. Proxmox host has 24 cores at ~4% load, so 3x8 = 24 vCPU is 1:1 with
zero oversubscription. In-place tofu update (cores change is pending until a per-node VM stop/start);
rolled one node at a time to keep etcd quorum. Comment also corrected 16->24 GiB (stale).

The container-workload and egress-class L1 fixtures use auth.mode=forward-auth, so the renderer now
emits the keycloak backend egress allow for them too. Regenerate the committed goldens to match the
canonical render. MERGE GATE: PASS.

App SSO broke cluster-wide after the Cilium 1.16.5->1.20.1 upgrade: the CVE-2025-30162 fix (in
>=1.16.8/1.17.2) makes the shared Gateway's L7 proxy re-evaluate a pod's egress policy against
Keycloak's REAL backend cluster identity (enforce_policy_on_l7lb) when it hairpins to keycloak.home.
'toEntities: world' matches the Gateway VIP at L3/L4 but not the resolved keycloak identity at L7, so
OIDC discovery/token 403'd ('Access denied') for every app with a NetworkPolicy (gitea/nextcloud/
semaphore/headlamp/crafty...); Grafana survived only because monitoring has no NetworkPolicy.
Fix: explicit toEndpoints egress allow to the keycloak backend for SSO apps.
- catalog/render.py: emit it for auth.mode in {oidc,forward-auth}; re-rendered 8 app goldens.
- platform/headlamp + platform/crafty: hand-written policies get the same allow.
Split-horizon design unchanged. Verified live: headlamp-ns -> keycloak discovery 403 -> 200.

The browser-mfa conditional-user-role authenticator used config key 'condition.evaluated.user.role',
which is not a real Keycloak property — the role resolved to null, so Keycloak logged 'Invalid role
name submitted: null' and the REQUIRED conditional-OTP step threw, 403-ing every platform-admins login
(Headlamp, Grafana admin, etc.). Correct key for Keycloak 26 is condUserRole=platform-admin.

Adds NodeCPUPressureHigh (CPU PSI 'some' > 15% for 15m) and NodeCPULoadHigh (load5/core > 1 for 15m)
to platform-health.nodes, plus a 'Nodes — CPU / Memory Pressure' Grafana dashboard (PSI + load-per-core
+ utilization). These surface the bursty CPU contention that averaged CPU%/kubectl top hides — the
signal behind 'spikes cause blips of delay'. Makes the 6->8 vCPU resize measurable.

Both were pinned at ~98% of their limits (Prometheus 2002/2048Mi, Grafana 499/512Mi) with no
headroom for TSDB compaction / dashboard-render spikes — the classic OOM setups. Nodes are 24Gi at
38-44% used (~14Gi free each; the '~22 GiB ceiling' comment predates the 16->24Gi node bump), so the
extra headroom is comfortable. Grafana request 256->384Mi, Prometheus request unchanged.

A node rebuild (tofu -replace / fresh OS) wipes host-level config Flux/Helm don't manage.
site.yml omits kube-vip.yml and vpn.egress.gateway.yml, so a re-provision missed the node-host
OpenVPN on k3s-dev-3 and dropped all egress-class=vpn pod traffic. Document the node-host layers
that must be re-run after any re-provision, and correct the stale author-only banner (these plays
are live).

Text-only cleanup after the upgrade campaign. Updates stale version
strings, prose, and comments to the verified current facts; no
Kubernetes behavior or version pins changed except the kubectl
toolchain bump (below).
Verified facts applied: k3s v1.36.4+k3s1, Debian 13 trixie,
Cilium 1.20.1 / Gateway API v1.6.1, Longhorn 1.12.1, node RAM 24 GiB,
dedicated virtio2 SSD etcd disk per node, Velero chart 12.x / v1.18,
Grafana 13.2.0.
- Version strings across infra/ and platform/ READMEs + comments
- kubectl toolchain 1.31.4 -> 1.36.4 (devcontainer/ci/conformance
versions.env; 1.31 vs a 1.36 cluster exceeded the +-1 skew)
- Retired-single-apps-Kustomization refs -> apps-wave-0/1/2 + apps-vms
with per-wave SOPS decryption (flux/clusters docs + bootstrap.sh)
- COMPLETED/historical banners on the three executed plan docs
- Resolved TODO(WS-SEC) markers -> Renovate-maintained ranges
- Appended dated DECISIONS-LOG entry (2026-08-30) superseding the
2026-08-26 LIVE STATE line
Left as revalidation items (not blind-edited): external-snapshotter
v8.2.0 vs 1.36, Cilium ext_authz/forward-auth relevance under 1.20.1,
conformance ImageVolume feature-gate assertions under 1.36.

Grafana 12.x bundled in kps 88 OOMKilled (exit 137) at 256Mi during grafana-apiserver/unified-storage
startup — no fatal log, just SIGKILL. The new Grafana pod never became Ready, so Helm --wait ran the full
20m and rolled back to 65.8.1 every time. 512Mi holds.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The 65->88 multi-major upgrade exceeded the default 5m Helm timeout (full operator/KSM/
node-exporter + Prometheus/Alertmanager StatefulSet rollout), so Flux rolled back to 65.8.1
four times and Stalled, blocking the platform kustomization and everything downstream.
CRDs pre-applied server-side at operator v0.93.1.

All 3 k3s nodes re-provisioned to Debian 13 (kernel 6.12) via immutable tofu -replace,
one at a time, primary/leader last (secondary-join to avoid cluster-init split-brain).
- variables.tf image defaults -> debian-13-generic (generic, not genericcloud)
- k3s_server: ensure /etc/rancher/k3s exists (fresh-node re-provision fix)
- gitignore vendored ansible collections (installed for re-provision)
