feat(backup): the overlay picks the credential — BACKUP_CREDENTIALS_SUFFIX
The previous commit created the two halves. This one wires the choice, so dev renders MinIO
credentials and prod renders R2 credentials from the SAME base manifests (R-ENV-02: the
overlay patch is the entire difference between environments; no base manifest is forked).
cluster-vars BACKUP_CREDENTIALS_SUFFIX base "" | dev "" | prod "-prod"
velero HelmRelease credentials.existingSecret: velero-cloud-credentials${BACKUP_CREDENTIALS_SUFFIX}
3x CNPG Cluster s3Credentials.*.name: <db>-backup-credentials${BACKUP_CREDENTIALS_SUFFIX}
ONE SUFFIX, NOT FOUR SECRET-NAME KNOBS. Four independent knobs can be updated three-quarters
of the way, leaving one consumer reading the OTHER environment's key with nothing rendering
wrong — and StrictPostBuildSubstitutions cannot catch that: strict mode fails on an UNDEFINED
variable, never on a defined-but-stale one. With one suffix the four move together or not at
all. The cost is that the rendered Secret name is not greppable from the consumer, so both
kustomizations spell the two names out in full beside the resources.
THE BASE DEFAULT IS "" AND THAT IS LOAD-BEARING. It renders the UNSUFFIXED names — objects
that exist in every render, and that dev is running today. The alternative failure mode is
strictly worse than the shared-Secret state this replaces: velero's pod hangs in
ContainerCreating forever when `existingSecret` names a missing Secret (the volume never
mounts), and a CNPG Cluster whose s3Credentials Secret is absent stops archiving WAL — which
under archive_mode=on is a filling pgdata PVC, not a missing backup. So an unresolvable
default breaks the referencing cluster HARDER than a wrong key does. Both overlays state the
value explicitly anyway, so neither inherits it silently.
Prod's overlay change is a cluster-vars op only. The velero Flux Kustomization patch is
untouched (it stays decryption-only, and velero stays suspended on prod).
VERIFIED — `kubectl kustomize --load-restrictor LoadRestrictionsNone` on clusters/dev and
clusters/prod for the cluster-vars values, then on each of the four affected tiers (platform,
platform-config, platform/velero, apps/wave-0) piped through `flux envsubst --strict` with
that environment's variables:
strict envsubst PASSES for all 8 (env x tier) combinations
dev velero existingSecret velero-cloud-credentials
dev keycloak/nextcloud/semaphore-db <db>-backup-credentials (both key refs each)
prod velero existingSecret velero-cloud-credentials-prod
prod keycloak/nextcloud/semaphore-db <db>-backup-credentials-prod (both key refs each)
both all EIGHT Secret objects present in the rendered output (dev and prod alike)
no `${...}` survives in any rendered tier except gitea's three DELIBERATE `$${...}` shell
escapes in apps/wave-0, which are pre-existing and unrelated.
Read alongside the endpoints the same overlays already set, the two environments are now
isolated on credential AND target:
dev velero s3://velero (root) + cnpg s3://cnpg @ http://192.168.1.9:9000 region us-east-1
prod velero k3s-prod-backup/velero + barman prefix @ https://<acct>.r2.cloudflarestorage.com region auto

feat(backup): prod's off-cluster DR lands on R2 — and stops the WAL clock
Prod has been archiving WAL to `TBD-PROD-S3-BACKUP-ENDPOINT` since bootstrap. Verified live 2026-09-07 on all three CNPG Clusters: ContinuousArchiving=False, "unexpected failure invoking barman-cloud-wal-archive: exit status 4". Because archive_mode is ON, that is not a degraded backup — it is a DISK-FULL CLOCK. Postgres will not recycle a segment it has not archived, so keycloak-db's pgdata PVC is at 579 MiB used / 4360 MiB free and climbing monotonically. When it fills, the primary PANICs and takes SSO down, and with it kubectl OIDC, Grafana, Headlamp, Gitea and forward-auth. Wiring the endpoint is what lets Postgres drain the whole accumulated backlog in one pass. THE KNOB LAYOUT (three new, one repurposed) and why it is shaped this way. The operator created exactly ONE R2 bucket, `k3s-prod-backup`, but the two backup tools want differently-SHAPED values: the Velero chart takes `bucket` and `prefix` as separate fields, while CNPG's barmanObjectStore.destinationPath is one full s3:// URL whose first path segment IS the bucket. So: S3_BACKUP_ENDPOINT dev http://192.168.1.9:9000 prod https://<acct>.r2... S3_BACKUP_REGION dev us-east-1 prod auto VELERO_BACKUP_BUCKET dev velero prod k3s-prod-backup VELERO_BACKUP_PREFIX dev "" prod velero CNPG_BACKUP_PATH dev s3://cnpg prod s3://k3s-prod-backup/barman There is deliberately NO separate `S3_BACKUP_BUCKET`: CNPG's bucket already lives inside CNPG_BACKUP_PATH, and a second knob holding the same bucket name twice is a rotation waiting to drift. Three knobs, each shaped for its own consumer, and no two of them can contradict each other. TENANCY. Inside k3s-prod-backup, velero and barman get disjoint TOP-LEVEL prefixes — s3://k3s-prod-backup/velero/ and s3://k3s-prod-backup/barman/<cluster>/ — with the bucket ROOT left empty so a misrendered prefix lands somewhere obviously wrong instead of silently colliding. This is not tidiness: Velero ADOPTS every backup under its location and TTL-DELETES it on retention, so an overlapping prefix would let it reap WAL segments; and interleaving two Postgres servers' WAL into one prefix corrupts the chain outright. Dev↔prod isolation is doubly independent — different endpoint AND different bucket names — so neither cluster can reach the other's objects even with a mis-substituted prefix. DEV IS UNCHANGED, BYTE-FOR-BYTE, and that is asserted rather than assumed. Base defaults are dev's LIVE values (verified against the running cluster: BSL bucket=velero with NO prefix, region us-east-1; all three CNPG Clusters ContinuousArchiving=True at s3://cnpg on the MinIO), and the dev overlay now restates all five explicitly for the same reason LONGHORN_DATA_PATH is restated — a silent drift in base would ORPHAN the backups dev's PROVEN restore depends on. The empty-prefix case was the one real risk, and it is settled empirically: with prefix "" the chart omits objectStorage.prefix from the rendered BackupStorageLocation ENTIRELY (helm template, chart 12.1.0), so dev's live BSL is unchanged, not merely equivalent. R2's TWO GOTCHAS, both wired up front: - region must be exactly `auto`. head-bucket answers {"BucketRegion":"WNAM"}, which is a PHYSICAL LOCATION HINT, not a signing region. This was hardcoded us-east-1 inside the Velero HelmRelease — correct-by-accident for MinIO, wrong for anything else — so it is a knob now. - checksumAlgorithm: "". velero-plugin-for-aws v1.14.2 bundles an AWS SDK with flexible checksums on by default and sends x-amz-sdk-checksum-algorithm / x-amz-checksum-crc32 on every PUT; R2 rejects those with HTTP 400 InvalidArgument, failing every backup and every kopia blob upload. It must be PRESENT-but-empty (the plugin branches on the key existing), and the chart does emit an empty value — verified by rendering it. Harmless against MinIO, so it is unconditional rather than a fourth knob. WHAT THIS DOES NOT DO. Velero stays SUSPENDED on prod. `spec.suspend: true` is owned by field manager `flux` (verified: kustomize-controller's managedFields do not include f:suspend), so server-side apply will not strip it, and nothing here declares suspension — which would also trip R-ENV-03, since a prod overlay may patch only cluster-vars and a Flux Kustomization's `decryption`. Unsuspending is the operator's, after `standup.sh --s3-endpoint <r2> s3check` proves a round trip. NO DNS KNOB IS TOUCHED. BASE_DOMAIN stays prod.home.keithjackson.dev and every EXTERNALDNS_* value is untouched. The apex inversion on work/prod-standup-campaign was deliberately NOT carried: this branch ports that branch's R2 reasoning knob by knob, and merges nothing. VERIFIED: ci/l0.sh green (flux-postbuild-substitution 272 assertions, 0 hazards, 33 knobs defined / 28 referenced, every new token resolved in BOTH overlays); render-golden, lint, schema, spec-immutability green; touched requirement R-STATE-03 covered.

feat(ha): the CNI dials the control-plane VIP — kube-vip becomes a CNI prerequisite
OPERATOR DECISION 2026-09-06: "use the VIP as intended — a virtual address to reach
the cluster and provide fault tolerant HA. Without a change it will not work in HA."
THE DEFECT. Cilium's kube-proxy replacement dialled a SINGLE NODE. Re-confirmed live
before changing anything: all three prod cilium-agent pods carried
KUBERNETES_SERVICE_HOST=192.168.2.10 — k3s-prod-1's own address — while the kube-vip
VIP 192.168.2.9 was Running on all three nodes with a held lease. Lose prod-1 and the
CNI's control-plane path is dead on an "HA" cluster. clusters/prod's own comment said
the value must be the VIP and NOT .10, then called it "Not yet decided" — I treated
that stale comment as an open question when the evidence already settled it.
SPLIT, NOT REPOINT, because k3s_api_host had two consumers with opposite needs:
k3s_api_host unchanged — the FOUNDER's IP: the cold-bootstrap join
target and a tls-san. infra/tofu/outputs.tf GENERATES this
name, so renaming would ripple into tofu and the runbooks.
k3s_apiserver_endpoint NEW = {{ kube_vip_address }} — the HA address; what Cilium
consumes. Derived, not restated, so an environment overrides
ONE line and the VIP, the SAN and the CNI endpoint move
together. Prod needed no new override.
THE SECOND HAZARD, WHICH MY BRIEF DID NOT NAME and the agent found: pointing Cilium at
the VIP breaks a COLD bootstrap for the same reason the join would — site.yml ran
node-baseline -> k3s -> cilium, so Cilium would install against an address nothing
announced yet. That is the 2026-09-01 deadlock shape. Fixed by SEQUENCE, not value:
site.yml now imports kube-vip.yml BETWEEN k3s and cilium. It cannot go earlier
(kube-vip is a k3s auto-deploy manifest, so it needs a cluster) and it works there
because the DaemonSet is hostNetwork with KUBERNETES_SERVICE_HOST=127.0.0.1 — needing
neither CNI nor kube-proxy. roles/kube_vip gained a read-only `wait_for` on the VIP so
a cold run stops THERE with a named cause instead of surfacing as unreachable agents.
Also fixed a pre-existing bug that only mattered once this play joined site.yml: the
role's read-only interface probe ran without `check_mode: false`, so under --check it
was skipped and the assert fired with a misleading "set kube_vip_interface explicitly".
VERIFIED BY ME, not just reported:
renders dev K3S_API_HOST=192.168.1.49 prod=192.168.2.9 (each environment's VIP)
cilium template consumes k3s_apiserver_endpoint, not k3s_api_host
cold join still `--server https://{{ k3s_api_host }}:6443` — the founder
order site.yml: node-baseline -> k3s -> kube-vip -> cilium -> verify -> flux
gate full CI gate PASS
Agent-side, additionally: in-memory render of cilium-values.yaml.j2 per host showing
k8sServiceHost=the VIP with the join still on the founder; k3s_tls_sans renders
['.10','.9','127.0.0.1','.11','.12'] so NO cert reissue and NO k3s restart is involved
— .9 already answers under full CA verification; and --check --diff of kube-vip.yml
against prod reported 6 ok / 0 changed, i.e. the role edits change nothing about the
kube-vip prod already runs.
ha-control-plane-as-code 92 -> 112 assertions, turning two escalations into machine
checks: the Cilium template must use the endpoint var; the endpoint must derive from
kube_vip_address and k3s_api_host must not; per environment K3S_API_HOST must equal
that environment's VIP and be none of its node IPs (the [parity] contract, now
machine-checked rather than a comment); site.yml must order k3s -> kube-vip -> cilium.
Every new assertion mutation-tested and bites. One honest negative recorded: reverting
only the BASE default is not caught, because both overlays patch the key — the check
reads effective per-environment values, so the base default is unguarded.
APPLY ORDER, and this is the operator's step — nothing was applied:
PROD FIRST, and it is the low-risk direction (prod is the broken one). Push and let
Flux reconcile platform/cilium: the value change rolls the cilium-agent DaemonSet
ONE NODE AT A TIME (maxUnavailable: 1 — the knob that bounded the 2026-09-01
incident), it will not proceed past an unready pod, existing datapath survives an
agent restart, and .9 is already live before the change lands.
DEV SEPARATELY, operator present. Same mechanics but live dev agents dial
192.168.1.50, and dev is mid-DNS-migration on dev-live. Do not fold it into that.
ANSIBLE: nothing to run for either live cluster; the Ansible half matters only for a
cold build. Remove the now-redundant standalone kube-vip.yml step from any runbook.
NEW NAMED GAP, unwritten: the L2 test cannot assert the running agents' live
KUBERNETES_SERVICE_HOST, which is the drift the L0 check cannot see. Recorded in that
test's gap list.

fix(gitops): CDI cold-start deadlock repaired IN THE GRAPH, not by a pre-apply
`platform-config` applied the CDI CR *and* cdi-storageprofiles.yaml in ONE pass.
StorageProfile's CRD does not exist until cdi-operator reconciles that CR, and
Flux server-side dry-runs every object before applying any — so the unknown kind
aborted the tier, the CR was never applied, the CRD was never created, and the
tier could NEVER converge. Observed on prod: cdi-operator Available 12h, no CDI
CR, no storageprofiles CRD, every downstream tier blocked.
The profiles now live in their own tier ./platform-config-cdi with
dependsOn: platform-config and wait: true. Because dependsOn is REVISION-gated
and platform-config runs wait: true, the CDI CR must be applied AND healthy —
exactly the event that creates the CRD — before the profiles are applied. Cold
clusters order themselves. `standup.sh crds` is retained as a fallback for
clusters already stuck, and because it is idempotent.
THE GENERALISABLE RULE (recorded in clusters/README.md): a CR whose CRD is
created by a CONTROLLER AT RUNTIME is second-order and needs its own pass.
cdi-operator.yaml registers exactly ONE CRD (cdis.cdi.kubevirt.io); storageprofiles,
datavolumes, datasources and dataimportcrons appear only after it reconciles the
CDI CR. An audit found StorageProfile is the only second-order kind in
platform-config — KubeVirt, CDI, KeycloakRealmImport, CNPG Cluster,
VolumeSnapshotClass, ClusterIssuer, PrometheusRule, ServiceMonitor and the Cilium
L2 CRs all have their CRD in git or in a chart.
Moving the CDI CR up into `platform` was rejected: that would put CDI's health on
the tier the CNI gates and everything waits on — the mistake the oauth2-proxy and
headlamp splits exist to undo.
apps-vms gains dependsOn: platform-config-cdi. LOAD-BEARING, not cosmetic:
apps/vms/unifi/20-datavolume.yaml provisions on storageClassName: longhorn-vm and
its comment claimed platform-config guaranteed the profiles — which this move
would have silently falsified.
THE PRUNE TRANSIENT, MEASURED RATHER THAN ASSUMED. platform-config has
prune: true, so it deletes both profiles once, CDI recreates them with empty spec,
and the new tier re-applies the overrides ~30-60s later. Compared our override
against CDI's unaided inference for the same Longhorn provisioner on dev:
longhorn-vm (we override) spec RWX/Block -> status ReadWriteMany/Block
longhorn-static (no override) spec unset -> status ReadWriteOnce/Block
Both infer cloneStrategy: snapshot. So cloneStrategy is NOT at risk; accessModes
IS — unaided CDI gives RWO. A DataVolume provisioned on longhorn-vm inside the
window would be stamped RWO/Block and be PERMANENTLY non-live-migratable. Flux can
no longer cause it (apps-vms gates on the new tier); a human must not do it by hand.
Corroborating evidence that the recreate happens at all: dev has 5 StorageClasses
and 5 StorageProfiles, three with fluxOwner=NONE, spec unset and status populated
— CDI creating and inferring them with no Flux involvement.
MERGE PRECONDITION: `flux get kustomization platform-config` must be Ready on the
target first. If it is not, the profiles are pruned and sit at CDI defaults until
it recovers — and prod was in that state hours earlier. Fallback is the two-step
the Cilium move used (merge with prune: false, verify the ownership label moved,
restore prune: true).
substituteFrom: cluster-vars is declared even though the manifest has no ${TOKEN},
deliberately: conformance/tests/l0-static/flux-postbuild-substitution only audits
paths whose Kustomization declares it, so omitting it would move the file OUT of
the audited set — a blind spot for a future literal-token ship. Gate confirms it
stayed in (path=./platform-config-cdi files=2 defined=0 hazards=0). No SOPS
decryption stanza: the moved file is two plain CRs, so no overlay change was needed.
VERIFIED INDEPENDENTLY OF THE AGENT: platform-config renders 0 StorageProfile
while keeping the CDI and KubeVirt CRs; platform-config-cdi renders exactly the
two profiles; the graph is byte-identical across dev and prod with apps-vms
carrying both edges and no cycle. Full CI gate PASS.
KNOWN FOLLOW-UP: bootstrap/standup.sh TIER_ORDER does not yet include
platform-config-cdi, so `resume` will not wait on it. Another agent holds that
file; the PM will add it.

feat(dns): per-environment BASE_DOMAIN — prod moves to its own subdomain
INCIDENT FIX. Prod's external-dns DELETED EVERY ONE OF DEV'S PUBLIC DNS RECORDS. Both
clusters ran policy: sync against the SAME Cloudflare zone with the SAME implicit
txtOwnerId (`default`), so prod believed it owned dev's records, found no matching sources,
and removed them plus their TXT registry entries. Dev recovered ~30s after prod was scaled
to 0; verified restored against Cloudflare directly (my first check went through a pfSense
override and falsely showed healthy — local resolvers are not evidence about public DNS).
THE MISS WAS MINE, and it was a failure of imagination in how I briefed every agent. I put
"never touch dev" in brief after brief and enforced it — separate kubeconfigs, verified
--limit, sha-checked dev's kubeconfig before and after. Every one of those guards held. NONE
of them covered SHARED EXTERNAL RESOURCES. Prod reconciling its OWN correctly-authored
manifests reached across a third party and destroyed dev's state. Cluster-to-cluster
isolation was verified; the dependency that mattered was cluster-to-Cloudflare.
Operator's architecture: dev -> *.dev.home.keithjackson.dev, prod ->
*.prod.home.keithjackson.dev, apex CNAME <svc>.home -> <svc>.prod.home.
PHASE 1 ONLY (this commit): prod moves to its own subdomain. DEV IS NOT MIGRATED and its
effective hostname stays home.keithjackson.dev, so dev renders byte-identically and nothing
live moves. That alone ends the collision and unblocks prod. Phase 2 (dev -> dev.home. +
apex CNAMEs) is deferred to when the operator is present: it relocates Keycloak's issuer and
12 clients' redirect URIs, forces a rolling k3s restart and kubectl SSO re-issue for every
user, and moves gitea.home. — which is BOTH the GitOps source and the current push target.
BASE_DOMAIN WAS A DEAD KNOB — it existed in cluster-vars but the status report flagged it as
referenced by nothing, because hostnames were hardcoded throughout. Now real: 141 refs.
Searched the AUTHORITATIVE reconciled set by resolving each Flux spec.path transitively via
conformance/lib/status.py — the same resolver the L0 gate uses, so "what Flux reconciles"
has one definition. 185 occurrences across 47 files in 154 reconciled files. Tokenized:
Gateway listeners, the wildcard Certificate, coredns-custom, external-dns, Keycloak
instance/realm (26 redirect URIs), oauth2-proxy, Grafana OIDC, all HTTPRoutes, Homepage's 15
links, 30 runbook_urls, unifi cloud-init, render.py's ZONE constant (which drove
--oidc-issuer-url/--cookie-domain/--whitelist-domain on every forward-auth sidecar) and 11
catalog/ ServiceDefinitions re-rendered canonically. Left alone: 43 comment/prose
occurrences and non-reconciled paths.
TWO THAT CANNOT BE TOKENIZED, flagged not forced:
- headlamp's OIDC URLs live inside a SOPS-encrypted Secret; re-encrypting rewrites the MAC
over every value and the OFFLINE harness cannot verify it (kustomize does not decrypt),
so an error would break live-dev SSO with no pre-flight proof. Prod needs its own copy
anyway — client secrets are realm-scoped.
- kube-apiserver --oidc-issuer-url is a k3s SERVER FLAG, not a manifest, so Flux can never
reach it. Done on the inventory seam instead (k3s_base_domain -> k3s_oidc_issuer_url,
overridden in group_vars/k3s_prod). Verified per host: dev keeps the default, prod gets
prod.home.
EXTERNAL-DNS OWNER, the actual incident cause: txtOwnerId is now explicit per environment —
dev renders exactly `default` (the chart default it was already using, so its existing
records stay recognised) and prod gets `prod`. The BASE default is a NON-COLLIDING SENTINEL,
deliberately not `default`, so a future environment that forgets the knob owns nothing and
can delete nothing rather than silently inheriting dev's identity.
I OVERRODE ONE AGENT DECISION against our own prior finding: it narrowed prod's
domainFilters to prod.home.keithjackson.dev as defence in depth. FINDING F-DNS1
(DECISIONS-LOG 2026-08-17) already proved a subdomain filter DROPS THE PARENT ZONE —
ExternalDNS generates the record then skips it with "no hosted zone matching record DNS
Name". Prod would have published NOTHING. Set to the ZONE (keithjackson.dev) like dev.
Isolation comes from the subdomain split plus txtOwnerId, which is what the incident
actually needed and what a domain filter cannot provide.
DEV PROVEN UNCHANGED: 11 of 12 substituting paths byte-identical; the 12th differs by
exactly one line, `+ txtOwnerId: default` — the value dev was already using implicitly.
POSITIVE CONTROLS confirm the harness is not blind: perturbing BASE_DOMAIN moves 10 of 12
hashes (the 2 that don't provably contain no hostname), perturbing the owner id moves
exactly 1. Prod's rendered output has ZERO home.keithjackson.dev references outside prod.,
and its cert renders *.prod.home.keithjackson.dev — no overlap with dev's.
L0 substitution assertions 106 -> 254; BASE_DOMAIN is no longer flagged dead. Gate PASS.
PROD REMAINS SUSPENDED (platform + 10 downstream tiers) pending review; nothing applied.
Serves: R-ENV-02, R-DNS-01, R-DNS-02, R-DNS-03, R-TLS-01.

feat(prod): kernel fix + disk layout — prod nodes ready for k3s
Prod is being stood up now, without waiting for node 2's RAM upgrade. Three coupled
changes, all applied and verified on all three nodes.
=== 1. KERNEL >= 6.13 — now a PREREQUISITE, not a nice-to-have ===
A k3s SERVER that intermittently boots with 2.6 GiB is not a degraded node; it fails under
etcd plus its workload share, unpredictably, on any reboot. Fixed before k3s goes on.
roles/node_baseline gains a `kernel`-tagged block: asserts the suite matches the node's
Debian release, writes a deb822 trixie-backports source, installs, reads back the exact
version, writes a provenance/rollback note to the node. Scoped by
node_baseline_backports_kernel (default FALSE, true only in group_vars/k3s_prod) — chosen
over a hostname test so a fourth prod node inherits it from group membership. Verified:
--check against dev skips all 8 tasks on all 3 hosts. Two deliberate calls: `state: latest`
not `present` (linux-image-amd64 was already installed from main, so `present` would have
silently fixed nothing), and NO preferences.d pin (backports' NotAutomatic +
ButAutomaticUpgrades already gives 100/500; an explicit Pin-Priority: 100 would switch OFF
automatic security upgrades for the very kernel being installed).
Installed 7.1.8+deb13-amd64 on all three; 6.12.107 kept bootable.
THE DECISIVE PROOF: node 2 booted at MEMATTR=0xbeeb0018 — the EXACT address that gave it
2.6 GiB twice — and now reserves 634,904K instead of 13,958,980K. MemTotal 15.4 GiB. Same
address, handled correctly; not a lucky draw.
§0b's claim that a fixed kernel prints 'FW_BUG Corrupted...' is CONDITIONAL and was
corrected: >=6.13 has three rejection gates and only the third prints that line; all three
nodes hit gate 1 (version > 2). Proof instead is boot-independent — decompressing
/boot/vmlinuz on all three yields the FW_BUG and descriptor-size strings verbatim; neither
exists in 6.12.
TWO MORE BUGS IN MY OWN HEALTH CHECK, found because the fix couldn't otherwise be shown:
- MEMATTR_VERSION_RE matched (\d+) but the kernel prints that field with %d — SIGNED. Node
2's real value was -1569980416, which did not match, so state fell through to `clean` and
the node reported PASS "the kernel accepted it without complaint". A FALSE PASS on the
exact bug the check exists to find. Now (-?\d+).
- bad_version was WARN unconditionally, so a FIXED node would have stayed WARN forever.
Now keys on memattr_kernel_fixed: same line, WARN below 6.13, PASS at/above.
=== 2. DISK LAYOUT — Longhorn claimed, per-node paths DISCOVERED not hardcoded ===
Operator decision: reuse the ~424 GB partition; accept the shared-device I/O risk (dev's
etcd/Longhorn contention was on a spinning HDD, prod is SSD/NVMe).
Device paths differ per node (sda5 / nvme0n1p5 / sda5), so the role DISCOVERS the partition
via `findmnt --mountpoint` on a declared claim mountpoint rather than trusting inventory.
Per-host host_vars would have frozen today's hardware into inventory, where it goes stale on
the first re-image and the stale value's failure mode is mkfs on the WRONG partition.
Eleven fail-closed asserts before any write: real block device, not backing / /boot /usr
/var /home /tmp or active swap (built from the node's OWN gathered facts, never a hardcoded
list), already ext4, no foreign label, >= 100 GiB, and empty. Relabel, never reformat.
/srv verified empty first on every node (ls -A -> lost+found only; du 20K; the "5.1% used"
was ext4's default 5% root reserve).
=== 3. k3s DATA-DIR MOVED — /var was 11.8 GiB and would have killed etcd ===
Measured on the fully-deployed dev cluster: containerd 21-25 GB/node, /var total 58-70 GB.
Prod's /var is 11.8 GiB and held BOTH etcd and the image store, so prod would have filled
/var during its first image pulls — and a full /var means etcd cannot write its WAL. Cluster
death, not degradation, arriving during bring-up. Invisible when the disk decision was made,
because "etcd on root" sounded like the 30 GiB / rather than a separate 12 GiB /var.
Now: p5 -> /data (LABEL=k3s-data), with /data/longhorn and /data/k3s. Neutral names chosen
deliberately — the partition now has two tenants, and reusing /srv would make "claimed" and
"unclaimed" indistinguishable to the idempotency pivot, while a bare `data` label would make
a stranger's `data` volume look already-claimed and weaken an assert.
The transition off the existing LABEL=longhorn mount is DECLARED, not inferred
(node_baseline_data_retired_fs_label/_retired_mount, defaults ""), because changing the label
makes a claimed node answer "no" to the pivot and walk into the greenfield path. Self-retiring
once blkid -L k3s-data succeeds. THREE independent gates keep live dev out: retired vars
default ""; gated on longhorn_source == claim-mountpoint (dev is `device`); and the emptiness
assert fails closed on dev's 18 volumes even if both were defeated.
k3s_data_dir is one variable read by two roles (k3s_server --data-dir; node_baseline derives
the etcd mount). Role default is k3s's own default, so dev is unchanged and keeps its
dedicated etcd device. node_baseline_etcd_source becomes `shared-data-partition` and is
LOAD-BEARING: the role asserts per run that the filesystem backing the etcd dir really IS the
data partition — had the mount silently failed, etcd plus 21-25 GB of images would land back
on the OS filesystem invisibly until the disk filled.
LONGHORN_DATA_PATH is a new cluster-vars knob (R-ENV-02): base and DEV /var/lib/longhorn,
prod /data/longhorn.
DEV PROVEN UNCHANGED, which is the property that mattered — the live cluster has 18 Longhorn
volumes on that path. All 12 substituting Flux paths rendered through
`kubectl kustomize | flux envsubst --strict` for both trees: 12/12 per-file SHA-256 identical
and an identical aggregate SHA over every rendered dev byte. With a POSITIVE CONTROL showing
the same harness detects prod changing on exactly one line — an all-identical result is
worthless if the harness cannot see change. Live check after: dev's default-data-path setting
still /var/lib/longhorn, 18 volumes attached, 0 Kustomizations unready.
Idempotent: run 2 is changed=0 on all three nodes. Also fixed a real tag bug — include_tasks
does NOT propagate its own tags to included tasks (unlike import_tasks), so `--tags disks`
selected the include and ran nothing inside it while reporting success.
OPEN DEFECTS, tracked not forgotten: node 2's warm-reboot hang (one clean reboot since, NOT a
fix); and node 3 runs dhcpcd for its wifi interface, which rewrites /etc/resolv.conf on lease
renewal — the role's `contended` detection checks resolvconf and NetworkManager only, so node
3's decided resolvers will silently revert.
Gate: MERGE GATE: PASS. L0 substitution check 106 assertions.

feat(flux): give Cilium its own Kustomization — MERGE 1 of 2 (transition)
Cilium was one of ~12 components inside a single `platform` Kustomization with wait:true,
so the CNI's health was indistinguishable from eleven unrelated components in the tier's
Ready condition, and the only emergency valve was freezing the whole platform tier. This
repo already set the precedent in reverse (oauth2-proxy and headlamp were split OUT so
unhealthy leaves would not gate a tier); Cilium is the mirror image — the one component
that legitimately SHOULD gate everything.
New clusters/base/cilium.yaml: path ./platform/cilium, wait:true, prune:true, interval 1h
(a CNI does not need a 10m re-render cadence; kustomize-controller is source-triggered so
a push still reconciles immediately — the interval is only the drift-correction floor),
timeout 10m (a 3-node DaemonSet rollout with wait exceeds the 5m default),
dependsOn:[flux-system], and postBuild.substituteFrom: cluster-vars — the last is
LOAD-BEARING, not decorative: helmrelease.yaml references ${K3S_API_HOST} and
kustomize-controller now runs --feature-gates=StrictPostBuildSubstitutions=true, so
without it this Kustomization would fail immediately.
*** THE HAZARD WAS FAR WORSE THAN "the CNI gets pruned" ***
platform/cilium/namespace.yaml is the ONLY declaration of Namespace/kube-system anywhere
under ./platform, and the live object carries kustomize.toolkit.fluxcd.io/name=platform.
With prune:true, the moment ./platform/cilium leaves platform's path the stale set is not
"the Cilium HelmRelease" — it is `kubectl delete namespace kube-system`, taking coredns,
metrics-server, local-path AND Cilium. A full cluster kill, not a CNI kill.
TWO INDEPENDENT PROTECTIONS, deliberately not trusting either alone:
1. prune:false on `platform` for this transition merge — Flux's documented Procedure 1 for
moving resources between Kustomizations. Chosen over the per-resource
`kustomize.toolkit.fluxcd.io/prune: disabled` annotation because that needs THREE merges
and leaves the new Kustomization owning resources it can never prune.
2. The pruner's own owner-label filter. In v1.4.0, prune() passes Inclusions:
GetOwnerLabels(obj.Name...), so platform only deletes objects whose LIVE labels still
say name=platform. The new cilium Kustomization relabels all three to name=cilium on
apply, and platform.dependsOn:[cilium] is REVISION-GATED, so platform provably cannot
reconcile revision N until cilium has APPLIED revision N. The relabel deterministically
precedes the prune.
Protection 2 alone would probably have sufficed. Not betting kube-system on "probably".
NOTED FOR THE FUTURE, in-file: anyone moving a platform/* component must first check
whether it is the sole declarer of a shared Namespace — that turns a component-scoped
prune into a cluster-scoped one.
Verified: `kubectl kustomize platform` goes 88 -> 85 documents, 3 removed / 0 added /
0 CHANGED, and `kubectl kustomize platform/cilium` reproduces those 3 byte-identical
(sha256-matched). A pure ownership move; no Cilium value touched. L0 substitution gate
103 assertions (was 102), new cilium row, 0 hazards. Server-side dry-run against the live
cluster accepted both CRs. clusters/prod renders clean off the same base.
MERGE 2 (restore prune:true) follows only after verifying: 13/13 Ready; kube-system, the
HelmRelease and the HelmRepository all relabelled to name=cilium; platform's inventory no
longer lists them; and Cilium pod ages/restarts UNCHANGED from
cilium-2f8h8 r=0 2026-09-01T05:55:27Z / cilium-425m8 r=1 2026-08-30T13:25:10Z /
cilium-54cww r=0 2026-09-01T05:55:26Z, HelmRelease v11.

fix(flux): close the substitution race — platform dependsOn root + strict substitution (P0/P1)
P0 — clusters/base/platform.yaml gains `dependsOn: [flux-system]`. This is the actual fix for the incident, not the feature gate. Verified against kustomize-controller v1.4.0 `kustomization_controller.go :: checkDependencies` (our version): dependsOn is REVISION- gated, not merely Ready-gated — when the dependency shares a GitRepository, the dependent cannot reconcile revision N until the dependency has APPLIED revision N. Applying revision N is exactly what writes a newly-added cluster-vars knob. Graph verified mechanically, not by eye: built clusters/dev and clusters/prod and walked the resulting objects. `platform` was the ONLY Kustomization without a dependsOn, and all 11 substituting Kustomizations chain transitively through it (platform-config -> platform; the waves, apps-vms, oauth2-proxy, headlamp, homepage, crafty, velero -> platform-config). The "not chaining through platform" set is EMPTY, so this one edge protects the whole graph. DFS over the full edge set after the edit: no cycles. The root (clusters/dev/ sync.yaml) runs wait: false, which is what makes the edge deadlock-free — it reaches Ready on apply success without health-gating its children. Accepted trade-off, documented in-file: the root becomes a gate. A malformed manifest anywhere under clusters/<env> — including clusters/base — now stalls platform and everything downstream, where today it would not. Fail-closed, per doctrine. P1 — StrictPostBuildSubstitutions. MY PREMISE WAS WRONG about where this belongs and it matters: this repo deliberately does NOT use `flux bootstrap` (see bootstrap/flux/README). There is no gotk-components.yaml in git, and the live kustomize-controller Deployment carries NO Flux ownership labels — it was installed imperatively by `flux install` from bootstrap.sh and is not in Flux's inventory. `flux-system` self-manages the CR graph, NOT the controllers. Nothing under clusters/** can reach a controller flag. So it uses Flux's documented mechanism for hand-installed clusters: a new bootstrap/flux/components/kustomization.yaml wrapping `gotk-components.yaml` with a JSON-6902 patch appending --feature-gates=StrictPostBuildSubstitutions=true to kustomize-controller. JSON-6902 `add /args/-` deliberately, NOT strategic merge — a container's args is atomic and a merge patch would replace all five install-generated args. bootstrap.sh step 1 now renders (`flux install --export` into a temp dir, apply the patch, ASSERT the gate string is present so a future Flux bump that breaks the patch target fails loudly) then applies. FLUX_INSTALL_PLAIN=1 is a loud escape hatch. Nothing is vendored, so components can never drift from the pinned FLUX_VERSION. Rejected: vendoring gotk-components.yaml under the root's path (the root's prune: true would put Flux's own controllers and CRDs in a prune inventory), and shipping a partial Deployment as a Flux-managed resource (a future prune would delete kustomize-controller). ROLLOUT ORDER MATTERS. P0 arrives automatically on the next reconcile. P1 does NOT arrive on a git push — the controller Deployment is outside Flux's inventory, so an operator must re-run bootstrap.sh step 1, which restarts kustomize-controller (~10-20s; Flux is level-triggered so an interrupted reconcile is simply retried). P0 must be reconciled BEFORE P1 is rolled out: with the gate on but the ordering edge absent, the same race turns a transient empty render into a transient hard Kustomization failure. ALSO FIXES A PHASE-7 BLOCKER THIS CHANGE WOULD OTHERWISE HAVE CREATED. clusters/prod had no root Kustomization — dev/sync.yaml even carried the note "a prod overlay needs its own sync.yaml -> ./clusters/prod". With the new dependsOn, a prod bootstrap would have left platform blocked forever on a flux-system Kustomization that does not exist, and nothing downstream would ever reconcile. clusters/prod/sync.yaml is now authored, mirroring dev. Two further prod-overlay gaps found and DOCUMENTED, not guessed (PROD-PROVISIONING §7): prod has no SOPS `decryption` patch (every encrypted Secret would fail to decrypt — needs the prod age-key decision, a security choice not a copy), and no GitRepository source URL patch (needs a decision on whether prod tracks the same branch as dev, which would make a dev-facing merge reconcile prod). Substitution gate re-run: check OK, 102 assertions, 0 hazards. Gate: MERGE GATE: PASS. Serves: R-ENV-02, R-GITOPS-01, R-PLAT-01, R-ENV-03.

feat(env): tokenize hardcoded dev LAN addresses into cluster-vars (R-ENV-02)
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.
Serves: R-ENV-02. Task: T-7.1 (prerequisite). Gate: MERGE GATE: PASS.

Author the GitOps side of off-cluster backups against the on-Proxmox MinIO (http://192.168.1.9:9000, path-style; buckets velero + cnpg). Velero (R-STATE-03): - HelmRelease (chart 8.x / Velero 1.15) + velero-plugin-for-aws init container + node-agent kopia File System Backup (deployNodeAgent, uploaderType=kopia, snapshotsEnabled=false). BSL default -> bucket velero, s3ForcePathStyle. - Two daily Schedules: `daily` backs up the whole cluster's resources+PVC data (defaultVolumesToFsBackup opt-out) EXCEPT monitoring+unifi; `daily-resources-only` captures monitoring+unifi RESOURCES only (Prometheus TSDB, Loki 72h logs, and the ~7.4GiB UniFi VM disk are reconstructable — excluded from volume backup). - velero-cloud-credentials SOPS Secret (cloud INI key, ns velero). - Own non-gating Flux tier clusters/base/backup.yaml (dependsOn platform-config, wait:false) + clusters/dev SOPS decryption patch — mirrors headlamp. CNPG native Barman PITR (R-IDP-05 / R-STATE-03): - keycloak-db, nextcloud-db, semaphore-db gain spec.backup.barmanObjectStore (s3://cnpg/<cluster>, endpointURL MinIO, gzip WAL+data, 30d retention) + a daily ScheduledBackup (6-field cron, immediate) each. - Per-namespace scoped-key SOPS Secrets (<db>-backup-credentials), same-ns only. - render.py: emit-waves now recognizes <svc>-db-backup-credentials.sops.yaml as a DB-wave sidecar (+ self-test); wave-0 kustomization regenerated.

Onboard Crafty Controller (Minecraft panel) with Keycloak-gated web UI
Add Crafty Controller 4 (registry.gitlab.com/crafty-controller/crafty-4:4.10.8) as a platform component: a web panel that runs Java + Bedrock Minecraft servers as subprocesses in one pod + a 20Gi Longhorn PVC (mounted 5x by subPath). Auth = Option B (per-app oauth2-proxy reverse-proxy sidecar), since Cilium 1.16.5 cannot do ext_authz on the shared Gateway: - oauth2-proxy v7.8.1 sidecar (:4180) reverse-proxies to Crafty's self-signed HTTPS UI (127.0.0.1:8443), gated to Keycloak homelab realm group platform-admins. - Confidential `crafty` client provisioned live via kcadm + captured in the realm import; client secret + cookie secret via SOPS/age (mirrored in realm-clients). - Web UI: HTTPRoute crafty.home.keithjackson.dev -> Service :80 -> sidecar :4180. - Game ports: Cilium L2 LoadBalancer on VIP 192.168.1.55 (next free after .53/.54), starter set TCP 25565-25567 (Java) + UDP 19132-19134 (Bedrock), NOT auth-gated. - fsGroup:0 / runAsGroup:0 / runAsUser:1000 for the image's crafty:root identity on the root:root Longhorn PVC (the seerr fsGroup lesson). - Own non-gating Flux tier clusters/base/crafty.yaml (dependsOn platform-config, wait:false) + sops-decryption patch in clusters/dev — a leaf UI must never gate the platform. - Explicit default-deny NetworkPolicy + CiliumNetworkPolicies (platform namespace, not app-namespace, so Kyverno does not auto-generate the baseline). make -C ci gate green; kustomize build of platform/crafty, clusters/base, clusters/dev clean.

fix(monitoring): cap Prometheus TSDB by size to stop false absent()/==0 alerts
The 7 falsely-firing platform alerts (KeycloakDown, KeycloakDatabaseDown,
KubeAPIDown, KubeletDown, VPNTunnelDown, KubeVirtControlPlaneDown,
CDINoDefaultStorageClass) share ONE root cause, not per-rule label mismatches:
the Prometheus PVC is 100% full ("no space left on device" on every WAL commit).
Evidence from the live dev cluster:
- /prometheus is 4.8G/5Gi, 0 bytes free; every scrape logs "Scrape commit
failed ... write to WAL: no space left on device". Scrapes still return 200
(targets show healthy, lastScrape=now) but samples are never stored, so the
TSDB head froze at 2026-08-28 13:45 UTC while the pod clock reads ~19:33 UTC.
- Instant queries at "now" therefore return an EMPTY vector, so every
absent()/==0 platform rule trips. Evaluated at the last-good-sample time each
expr is correctly FALSE (keycloak-0/keycloak-db-1 ready=1, apiserver+kubelet
up=1 x3, tun0 series present, kubevirt control-plane expr empty, CDI default
present) — the rules are correct; the monitor was simply blind.
`retention` alone prunes only by AGE: this cluster is 3d2h old with 3d dev
retention, so time-pruning has NEVER run and 3d of block churn (~1.2Gi/day) plus
a WAL that ballooned past 1Gi overran the 5Gi disk. Fix adds a size-based
retention cap (new MONITORING_PROMETHEUS_RETENTION_SIZE knob) kept below each
env's PVC so Prometheus drops oldest blocks before the disk fills, and bumps the
dev PVC 5Gi->8Gi for real WAL/head/compaction headroom.
- platform/monitoring/kube-prometheus-stack.yaml: retentionSize: ${knob}
- clusters/base/cluster-vars.yaml: knob default 8GiB (base 10Gi PVC)
- clusters/dev/kustomization.yaml: PVC 5Gi->8Gi, retentionSize 5GiB
- clusters/prod/kustomization.yaml: retentionSize 45GiB (50Gi PVC)
- platform/monitoring/README.md: knob table + rationale
Deploy note (PM): the PVC is already 100% full, so Prometheus cannot self-prune
until it can write. The 5Gi->8Gi bump must land as a Longhorn online expansion
(operator PVC expansion / manual patch); once free space returns, retentionSize
keeps it healthy. Watchdog left untouched.

Deploy Homepage (gethomepage) as the apex landing dashboard aggregating links to cluster services, in its OWN non-gating post-platform Flux Kustomization (clusters/base/homepage.yaml, dependsOn platform-config, wait:false) — mirrors headlamp/oauth2-proxy so a leaf UI can never gate the platform chain. - platform/homepage/: plain manifests (ns, config ConfigMap, Deployment, Service, default-deny+Cilium ingress NP, apex HTTPRoute). Non-root pod, HOMEPAGE_ALLOWED_HOSTS, bundled mdi-* icons (DNS-only egress). - gateway.yaml: add https-apex + http-apex-redirect listeners for the bare apex (the *.home wildcard listener does NOT match it). Apex is already a SAN on the wildcard cert — no new Certificate. - Forward-auth annotated (auth-mode=forward-auth) but NOT enforced: the Gateway ext-authz mechanism is an unbuilt Phase-6 WS-NET TODO (same status as all other forward-auth apps).

platform: move Headlamp out of the gating platform tier + fix -session-ttl crashloop
Headlamp's HelmRelease sat in the wait:true `platform` Flux tier. Its pod crashlooped (`flag provided but not defined: -session-ttl` — chart 0.40.1 renders a container arg the appVersion v0.40.1 backend lacks; upstream kubernetes-sigs/headlamp#4883), and because it gated `platform`, the whole chain stalled: platform Ready=Unknown -> platform-config, oauth2-proxy, apps-wave-0/1/2 and apps-vms all Ready=False "dependency not ready". Part A (unblock + durable lesson): a leaf UI must never gate the chain. Move all Headlamp resources into a new non-gating Flux Kustomization clusters/base/headlamp.yaml (dependsOn platform-config, wait:false, SOPS decryption patched per-env in clusters/dev) — mirroring oauth2-proxy exactly. The new Kustomization owns the whole platform/headlamp component; its HTTPRoute moves from platform-config into platform/headlamp/kustomization.yaml. Removed headlamp from platform/kustomization.yaml and its httproute from platform-config/kustomization.yaml. Now a crashlooping Headlamp can never stall platform/platform-config/apps. Part B (make it start): pin the chart to 0.41.0 (`>=0.41.0 <0.42.0`). The backend added `f.Int("session-ttl", …)` in v0.41.0 and chart 0.41.0 pins that same image (appVersion == chart version), so chart+image realign; every arg the chart renders for our values is supported. OIDC config + per-user RBAC (clusterRoleBinding.create:false) unchanged. Gate: `make -C ci gate` PASS. Co-Authored-By: Claude Opus 4.8 <[email protected]> |

fix(flux): move oauth2-proxy to a post-platform tier (dependsOn platform-config)
oauth2-proxy is a leaf forward-auth service that depends on Keycloak + trusted wildcard TLS + split-horizon DNS. It lived in the gating `platform` Flux Kustomization (wait:true), so on a cold start it Failed until those dependencies existed, keeping the whole `platform` tier not-Ready. That in turn blocked `platform-config` — which brings up the very Keycloak instance, wildcard Certificate and L2 VIP oauth2-proxy needs (and previously carried oauth2-proxy's own httproute/servicemonitor) — from ever reconciling. A self-gating cold-start deadlock, twice-proven (DECISIONS-LOG sessions 7 & 9). Break the cycle by moving the whole oauth2-proxy component out of the `platform` tier into its own non-gating post-platform Flux Kustomization: - clusters/base/oauth2-proxy.yaml: new Kustomization -> ./platform/oauth2-proxy, dependsOn platform-config, wait:false, substituteFrom cluster-vars. - clusters/base/kustomization.yaml: reference the new Kustomization. - platform/kustomization.yaml: drop the oauth2-proxy component (no longer in the gating tier). - platform/oauth2-proxy/kustomization.yaml: pull in httproute + servicemonitor so the full component travels together. - platform-config/kustomization.yaml: drop the in-place oauth2-proxy httproute/servicemonitor refs (moved with the controller). - clusters/dev/kustomization.yaml: add the SOPS decryption patch for the new oauth2-proxy Kustomization (it now owns the encrypted credentials Secret that the `platform` Kustomization used to decrypt). Now `platform` reaches Ready without oauth2-proxy; platform-config brings up Keycloak/TLS/DNS; then oauth2-proxy reconciles against dependencies that already exist. wait:false guarantees its health can never gate anything above it. No config of oauth2-proxy itself changed — only its reconciliation tier. Co-Authored-By: Claude Opus 4.8 <[email protected]> |

fix(vms): drop postBuild substituteFrom on apps-vms — it corrupted VM cloud-init
Flux's postBuild.substituteFrom runs envsubst over the WHOLE manifest, including
the VM cloud-init userData. It was substituting every shell `${...}` in the UOS
install script (${UOS_URL}, the API-resolver ${...}) to empty — which is why the
first UOS install silently did nothing — and ${PIPESTATUS[0]} then broke the
build entirely ("missing closing brace"), blocking apps-vms reconcile.
VM manifests use no cluster-vars, so substitution is unneeded. Removed it; the
cloud-init shell now reaches the guest intact. (A future VM needing a cluster-var
must escape its shell `${...}` as `$${...}`.)

feat(vms): onboard UniFi OS Server as a KubeVirt VM on a non-gating track
First KubeVirt VM app + first real CDI http import. UniFi OS Server (UOS) is Ubiquiti's current self-host product (the .deb is deprecated); it bundles UniFi OS + Network app + its own datastore, so no MongoDB companion. - apps/vms/unifi: CDI DataVolume (Ubuntu 24.04 cloud image -> longhorn-vm RWX/Block, live-migratable) + VirtualMachine (evictionStrategy: LiveMigrate) with cloud-init that installs podman/slirp4netns/jq and runs the UOS installer NON-INTERACTIVELY. The installer URL is resolved at boot from Ubiquiti's public firmware API (fw-update.ui.com/api/firmware-latest) — always-latest, no pinned URL to maintain (currently UOS v5.1.37). - L4 exposure: two LoadBalancer Services (TCP+UDP) sharing a pinned, L2-announced Cilium VIP 192.168.1.54 (device inform/adoption + STUN can't ride the L7 Gateway); external-dns publishes unifi.home.keithjackson.dev. UI on :11443. - default-deny + additive CNPs (controller ingress, egress, and CDI-importer egress for the image pull). - clusters/base/apps-vms.yaml: NON-GATING Flux Kustomization (wait:false, dependsOn platform-config) — VMs are a separate lifecycle from the app waves, so a slow VM import/install can't stall the app tier.

refactor(apps): split monolithic apps Kustomization into dependency waves
Replaces the single `apps` Flux Kustomization with dependency-ordered waves
(apps-wave-0..2) so a crashlooping workload isolates to its wave + downstream
instead of stalling the entire app tier. Parallel within a wave, ordered across.
- catalog/render.py: compute waves by longest dependency-path depth over the
ServiceDefinition `dependencies:` edges (a `<svc>-db` is a leaf, so its
consumer lands strictly higher — the "DB below consumer" rule falls out of
longest-path, no special case). `--emit-waves` generates the per-wave
kustomizations + Flux CRs; `--wave-layout` places renders into the right dir.
wave 0: pihole gitea jackett plex qbittorrent nextcloud-db semaphore-db
wave 1: sonarr radarr nextcloud semaphore gitea-actions
wave 2: seerr
- apps/*.yaml -> apps/wave-{0,1,2}/ (byte-identical moves; SOPS files intact).
- clusters/base: apps.yaml removed; apps-wave-{0,1,2}.yaml added (dependsOn
chain: platform-config -> wave-0 -> wave-1 -> wave-2, prune+wait each).
- clusters/dev: one SOPS decryption patch per wave (load-bearing).

feat(dns): add GATEWAY_VIP cluster-var for split-horizon target (R-DNS-03)
Parameterize the in-cluster split-horizon target as GATEWAY_VIP (R-ENV-02): base
default = dev L2-announced Gateway VIP (10.73.0.240, first IP of the Cilium LB pool).
coredns-custom answers *.home.keithjackson.dev with ${GATEWAY_VIP} so the unified graph
holds across dev/prod via cluster-vars only. Prod overlay carries a TODO to set the prod
LAN VIP alongside the prod L2 pool range when hardware is built.

docs(vpn-egress): reflect ADR-0015 node-tunnel egress, retire gluetun narrative
The in-cluster Gluetun gateway is retired; VPN egress is now a node-level host OpenVPN split-tunnel (Ansible role vpn_egress_gateway) steered by a Cilium Egress Gateway policy with a host nftables kill-switch (ADR-0015). Credentials moved host-side to the Ansible vault. Update docs/comments only: - platform/vpn-egress/README.md: rewrite for ADR-0015 (live + conformance-green); drop the resolved "option 1 not viable with Gluetun" finding to a brief history note. - platform/kustomization.yaml: Phase 3 comment -> node tunnel + Cilium steering. - platform/kyverno/.../require-egress-class-label.yaml: ADR-0013 -> ADR-0015 steering. - schemas/servicedefinition.schema.json: egress=vpn description -> node tunnel + Cilium. - clusters/base/cluster-vars.yaml: reframe PIA_REGION / CLUSTER_POD_CIDR WHY comments to ADR-0015 (Cilium excludedCIDRs); both keys retained (still referenced/documented). - platform/vpn-egress/namespace.yaml: no privileged gateway pod under ADR-0015. - pia-credentials.sops.yaml / pia-custom-ovpn.sops.yaml: comment headers only note they are now UNUSED (creds host-side), retained pending cleanup; payloads untouched. No runtime manifest behavior, alert exprs, kustomization resources, or SOPS payloads changed. No spec-repo edits. Co-Authored-By: Claude Opus 4.8 <[email protected]> |

fix(vpn): narrow FIREWALL_OUTBOUND_SUBNETS to 10.0.0.0/16 (PF gateway overlap)
PIA's PF gateway 10.31.128.1 sits inside the /8 cluster-pool, so FIREWALL_OUTBOUND_SUBNETS=10.0.0.0/8 made gluetun route it around the tunnel and port forwarding timed out (getSignature to 10.31.128.1:19999). /16 covers actual pod allocations and excludes PIA's 10.31.x.

fix(vpn): enable gluetun server-list updater (bundled list was stale) + re-enable
CORRECTION: the connection failures were gluetun dialing RETIRED PIA IPs (46.246.x = dead → timeouts, which I mis-read as a network block). A fresh PIA .ovpn connects from the same host, and PIA's current SE Stockholm servers (158.173.x) are reachable. Cilium was independently cleared (default-allow, host-fw off, Hubble FORWARDED). Fix: UPDATER_PERIOD=24h so gluetun fetches PIA's current servers; keep OPENVPN_MTU/MSSFIX=1350 for the real Cilium-VXLAN 1450 pod MTU (data channel); PIA default UDP port. Re-enable vpn-egress. Full correction in DECISIONS-LOG. Co-Authored-By: Claude Opus 4.8 <[email protected]> |

fix(vpn): disable vpn-egress — network blackholes PIA IPs (not ports/MTU/cluster)
Decisive diagnosis: OpenVPN's outbound init packets are 14 bytes with zero replies (so MTU was never the blocker), pod UDP egress is healthy (NTP replies), but TCP 501/443 to PIA IPs time out while Google/Cloudflare are OPEN — across many PIA servers. This 192.168.2.x WiFi segment blackholes PIA's IP ranges (and intercepts DNS). Not code-fixable. Reverted the port/MTU red-herring env to PIA defaults; disabled vpn-egress pending an operator network fix (move to the unfiltered 192.168.1.x LAN, or unblock PIA on the router). Full trace in DECISIONS-LOG. Co-Authored-By: Claude Opus 4.8 <[email protected]> |

fix(vpn): PIA OpenVPN port 53 -> 8080 (53 is DNS-intercepted on this network)
Port 53 also got no PIA replies: this network transparently intercepts outbound :53, so dig works but OpenVPN-over-53 is swallowed. An NTP/123 probe from the host returned fine, proving arbitrary non-53 UDP works bidirectionally (so it's port-specific: 1197 conflict + 53 DNS-intercept, not a UDP block). Move to 8080 (community-verified for PIA, non-DNS, non-1197). Co-Authored-By: Claude Opus 4.8 <[email protected]> |

fix(vpn): hardcode OPENVPN_ENDPOINT_PORT "53" as string (Flux var int-coercion)
Wiring the port via "${PIA_OPENVPN_PORT}" made Flux/kustomize emit an unquoted
53 (int) after substitution, which k8s rejects for an env value ("expected
string, got 53"). Same gotcha as the Longhorn numberOfReplicas fix. Hardcode the
quoted string; cluster-var removed with a NOTE explaining why.

fix(vpn): PIA OpenVPN on UDP/53 (avoid home WAN:1197 conflict); re-enable vpn-egress
Operator identified the block: the home network NATs its own OpenVPN server on
WAN:1197, colliding with the cluster's outbound PIA-on-1197 flow (port-specific,
not a general UDP block — UDP/53 worked in tcpdump). PIA accepts OpenVPN on
53/1194/1197/1198/8080/9201; chose 53 (empirically proven to traverse this net).
- cluster-vars: add PIA_OPENVPN_PORT="53"
- gluetun: OPENVPN_ENDPOINT_PORT=${PIA_OPENVPN_PORT}
- re-enable vpn-egress; DECISIONS-LOG resolution noted

fix(vpn): PIA_REGION Sweden -> "SE Stockholm" (Gluetun OpenVPN region name)
Gluetun's PIA OpenVPN provider rejects "Sweden"; the valid PF-capable Sweden
region identifier is "SE Stockholm" ("SE Streaming Optimized" lacks port
forwarding). Preserves the operator's Sweden choice.

fix(vpn): define PIA_REGION + CLUSTER_POD_CIDR cluster-vars; correct pod CIDR + doc where
gluetun-gateway.yaml referenced ${PIA_REGION}/${CLUSTER_POD_CIDR} but they were never defined
in cluster-vars, and the README didn't say where to set them. Add both to
clusters/base/cluster-vars.yaml (ConfigMap data:, string values, Flux postBuild substitution).
CLUSTER_POD_CIDR is 10.0.0.0/8 (Cilium cluster-pool — pods get 10.x, confirmed live), NOT the
k3s 10.42.0.0/16 I'd assumed. README now names the file + format + per-env override + PF-region note.

feat(conformance): author R-TLS + R-DNS L2 tests; fix ExternalDNS zone filter
Phase-2 exit tests (were Phase-0 scaffolds), authored against the live platform:
- trusted-tls (R-TLS-01/03): in-cluster probe dials the gateway Service (env-agnostic
via --connect-to) with wildcard SNI and verifies the served cert CHAINS TO THE LE
STAGING ROOT (operator decision A; dev uses LE-staging per ADR-0006). Fixture embeds
the '(STAGING) Pretend Pear X1' root. Probes public + internal-only hostnames (R-TLS-03).
PASSES.
- dns-exposure (R-DNS-02): a LoadBalancer Service with an external-dns hostname; polls
public DNS until ExternalDNS auto-publishes the record; teardown + policy=sync removes it.
ExternalDNS fix (root cause of the DNS test): domain-filter was the platform SUBDOMAIN
home.keithjackson.dev, which filters OUT the actual Cloudflare zone keithjackson.dev
('no hosted zone matching record DNS Name' — record generated but skipped). Add a
DNS_ZONE cluster-var (keithjackson.dev) and set domainFilters to it. policy=sync +
txt-registry still only manage ExternalDNS-owned records (the pre-existing wildcard is
untouched). Resolves the file's WS-NET R-DNS-02 TODO.

fix(kyverno): correct chart webhook schema (map + forceFailurePolicyIgnore)
Kyverno HelmRelease install failed at Helm templating: config.webhooks was a
LIST [{failurePolicy, namespaceSelector}], but the kyverno 3.3.9 chart expects
config.webhooks to be a MAP (webhooks.namespaceSelector) — the chart helper reads
.namespaceSelector off the value directly ('can't evaluate field namespaceSelector
in type []interface {}'). Also, failurePolicy is not a per-webhook field here; the
chart's global switch is config.forceFailurePolicyIgnore.enabled (bool).
Fix: config.webhooks -> map with namespaceSelector (system+platform excludes);
add config.forceFailurePolicyIgnore.enabled = ${KYVERNO_FORCE_FAILURE_POLICY_IGNORE}.
Renamed the cluster-var KYVERNO_WEBHOOK_FAILURE_POLICY (Fail/Ignore) ->
KYVERNO_FORCE_FAILURE_POLICY_IGNORE (false base / true dev). Verified with
helm template (renders 73 objects, no error); gate PASS.

fix(platform): controllers/configs split so CRDs precede their CRs
Un-suspend deadlocked: the single platform Kustomization applies HelmReleases
(which register CRDs) AND custom resources of those CRDs (ClusterIssuer,
Certificate, Kyverno ClusterPolicies) in ONE pass. Flux's server-side apply
fails atomically ('no matches for kind ClusterIssuer') → nothing installs, so
the CRD-registering HelmReleases never run either. Classic ordering deadlock.
Fix (flux2 controllers/configs pattern, applies to dev+prod equally — no
R-ENV-02 divergence): add a platform-config Flux Kustomization (dependsOn
platform, wait) carrying the CRs; platform keeps only the controllers.
- New clusters/base/platform-config.yaml (path ./platform-config, substituteFrom
cluster-vars, no decryption — no SOPS content); wired into base + apps now
dependsOn platform-config (transitively waits for platform).
- platform-config/ references the CR files IN PLACE via ../platform/... (Flux
builds LoadRestrictionsNone; Kyverno policies must stay under platform/kyverno/
for the CI L0 gate). CR resources dropped from the platform
component kustomizations (cert-manager, gateway, kyverno).
- Authored the missing Cilium L2 resources (were only a TODO): CiliumLoadBalancerIPPool
(dev NAT 10.73.0.240-.250) + CiliumL2AnnouncementPolicy (ens*), so Gateway
LoadBalancer listeners get a VIP. Prod range must be parameterized later.
Verified: platform build has zero CRs; platform-config build has 2 ClusterIssuers,
6 ClusterPolicies, Certificate, Gateway, both Cilium L2 CRs; dev/prod build; gate PASS.

correction: credential-forward + unified graph; activate SOPS (author-first)
Operator directive: don't diverge architecture to avoid asking for credentials; provision them upfront via SOPS and keep the existing (unified) graph. Roadmap reconciliation: Phase 2 = Network/Storage/TLS/DNS/Ingress, so cert-manager/externaldns/gateway (the credential-gated pieces) ARE Phase 2; monitoring is Phase 4. Earlier A2/rollout scope was inverted by credential-avoidance. Reverts (credential-driven): remove clusters/dev/rollout/ + the $patch:delete's; restore unified base graph (dev = ../base + cluster-vars + SOPS decryption, R-ENV-02 intact); restore monitoring files (Phase 4). Kept non-credential improvements: tofu for_each/rejoin, Kyverno parametrization + webhook excludes. platform/kustomization.yaml now phased (single shared list): Phase-2 set = kyverno, cilium, longhorn, cert-manager, externaldns, gateway; later components commented with phase markers. SOPS activated: .sops.yaml at repo root; bootstrap/sops/secret-templates/*.yaml.example for all secrets (cloudflare x2, grafana, alertmanager-smtp, keycloak, oauth2-proxy, pia); bootstrap/sops/CREDENTIALS.md checklist; pre-wired commented cloudflare-api-token lines in cert-manager + externaldns; filled non-secret ACME email. Agents never touch real secret values (operator encrypts). Validated: kubectl kustomize dev(unified)/prod/platform(Phase-2 only), templates inert, make -C ci gate PASS.

phase2-prep: per-component no-secret rollout + component hardening (author-first)
Prep only — nothing deployed; running cluster untouched. Reconciliation graph (operator-approved Option A): author clusters/dev/rollout/ = 4 per-component Flux Kustomizations (kyverno->cilium->longhorn->monitoring, monitoring dependsOn longhorn). Dev overlay $patch:delete's the monolithic base platform/apps and adds ./rollout, so only the no-secret tier reconciles; the secret-blocked components are simply not created until hand-offs arrive. The no-secret tier carries no SOPS content, so it needs no sops-age key. prod is untouched (still builds the monolith). Convergence path coded in (delete rollout/ + the two deletes) — R-ENV-02 divergence flagged for architect review. Component hardening via cluster-vars (prod keeps strict posture): - KYVERNO_VALIDATION_ACTION Enforce->Audit(dev), _WEBHOOK_FAILURE_POLICY Fail->Ignore(dev), _ADMISSION_REPLICAS 3->1(dev); webhook namespaceSelector excludes system+platform namespaces. - MONITORING_STORAGE_CLASS var; GRAFANA_ADMIN_SECRET var (dev ''=chart default); Alertmanager SMTP/secret deferred to Phase-4 with verbatim re-enable markers. Cilium parity verified against the live CNI (no-op adopt). Validated: kubectl kustomize dev/prod/all-components, envsubst->YAML parse, make -C ci gate PASS.

fix(K1): uppercase cluster-vars keys to match component substitution refs
Flux postBuild.substituteFrom is case-sensitive; platform/ components reference
${UPPERCASE} tokens but cluster-vars keys were lowercase -> none would resolve
(literal ${...} would reach the HelmReleases). Uppercased the ConfigMap data
keys + the dev/prod overlay patch paths. Every component ref now resolves;
clusters/dev & clusters/prod build; gate green. Clears the K1 landmine before
any platform un-suspend.
