feat(cloudflared): Cloudflare Tunnel connector, Phase 1 (isolated, no traffic change)
Adds platform/cloudflared: a locally-managed tunnel whose ingress rules live in git. LAN/VPN-only hosts (plex, plex-vip, jackett, pihole, pihole-dns, semaphore, qbittorrent, radarr, sonarr, headlamp, unifi, crafty-mc) map to 404. The apex and *.home go to cilium-gateway-shared.gateway over TLS with matchSNItoHost. Last comes a catch-all 404. Nothing routes to the Kubernetes API. - 2-replica Deployment, hard node spread, non-root, pinned digest, PDB - default-deny plus an egress CNP: Cloudflare edge 7844/443, the Gateway, and Gateway backends by gateway-access=shared minus the LAN-only namespaces (needed because of the CVE-2025-30162 L7LB egress re-check) - PodMonitor plus two alerts that fire on absent series, with promtool tests - its own Flux Kustomization (dependsOn platform-config, wait:false, nothing depends on it), plus SOPS decryption patches in both overlays - placeholder credentials (SOPS-encrypted) so it can merge before enrolment - L0 cloudflared-ingress-rules, and a cloudflared_ scrape owner - runbooks/cloudflare-tunnel.md and decisions/2026-11-08-cloudflare-tunnel.md Co-Authored-By: Claude Opus 5.5 <[email protected]> |

fix(bulk-nfs): repoint at the TrueNAS (192.168.2.30); the PVs must be recreated, not reconciled
Both ZFS pools moved off the Proxmox host onto a standalone TrueNAS on 192.168.2.30 -- prod's OWN /24, so the pfSense crossing that made this knob load-bearing is gone, along with the DNAT at 192.168.2.102 it mounted through. Measured 2026-10-07: 192.168.2.102:2049 no longer answers; .30:2049 and :111 do. BULK_NFS_SERVER -> 192.168.2.30 in prod, base and dev. The dev value is marked inert (dev is decommissioned); it carries the real address only so nothing in the tree renders a host that no longer exists. THE OPERATIONAL POINT, and why this is not just a value change: a bound PersistentVolume's NFS source is immutable. Server dry-run, 2026-10-07: spec.persistentvolumesource: Forbidden: spec.persistentvolumesource is immutable after creation so Flux's apply FAILS rather than updating, and the pods keep their old, dead mount. The five PVs must be deleted and recreated -- safe, because Retain never touches data and render.py emits a pre-set claimRef so each PV rebinds its own PVC. The sequence is docs/BULK-NFS-STORAGE.md section 10 and is an OPERATOR action; this commit does not perform it. Pairs with the hazard already on the page: spec.nfs.server is unvalidated at create (any string binds) and immutable at update. A wrong value is accepted silently and then cannot be corrected in place. docs/BULK-NFS-STORAGE.md: sections 1 and 5 rewritten for TrueNAS -- the measured exports, the service settings that decide whether uid 1000 survives the wire, the three stale ZFS sharenfs properties that had to be cleared, and the ACL hazard (acltype=nfsv4 + aclinherit=passthrough means one click in the ACL editor propagates to the whole future library). Section 7 rewritten now that the placeholder is gone, section 9 retargeted from dev to prod, section 10 new. Sections 2/3/4/6 are unchanged by the move.

fix(vpn-ingress): keep the server key in source through SOPS, not as an out-of-band Secret
Operator correction: secrets are kept in source through sops. #55 shipped the WireGuard server private key as a Secret to `kubectl create` by hand. Two real costs, not just a convention break: * R-SEC-01 / spec docs/07 -- secrets live in source, SOPS-encrypted, and reach the cluster only through Flux. * It broke DR for the one credential that cannot be re-derived. A rebuild restores everything in git; it does not restore a hand-made Secret, and losing this key means re-enrolling EVERY device, because each client profile pins its public half. #55 papered over that with "keep a copy in your password manager". (Note secret-provenance did NOT forbid the original shape -- it scopes to app-namespace=true and vpn-ingress is deliberately a platform namespace. The rule broken was the written requirement, not an enforced control.) An agent still must not mint a long-lived private key (CLAUDE.md §6), so the file is committed ALREADY ENCRYPTED with `privatekey: REPLACE-ME`. That makes the wiring complete and green from the first commit -- resource line plus both overlay decryption patches -- leaving the operator exactly one act: replace the value. A commented-out resource to uncomment later is the "in git, no generator entry, reviewed, merged, still broken" shape this repo keeps hitting. The init guard is now a validation rather than an emptiness check: the value is piped through `wg pubkey`, which accepts only a real curve25519 private key, and the pod names which case it hit -- placeholder, empty, mangled, or (the silent one) still `ENC[` ciphertext because an overlay is missing its decryption patch, which otherwise applies cleanly with every Flux condition green. Second, independent finding that also fixes #55's step 2: `wg` is on the HOST only and `sops` is in the CONTAINER only, so `sops -d | wg pubkey` cannot run in one shell -- the command #55 documented could not have worked. Every step is now split by where it runs, and the written key is verified by comparing sha256 digests rather than printing anything. `qrencode` is on neither, so the QR step says so and gives the install command. Touches clusters/** and adds a **/*.sops.yaml, so approval-policy will block pending the operator's /approve-override. Deliberately not posted by me.

feat(pm-agent): an in-cluster AI Program Manager that turns Gitea issues into pull requests
A service that reads this repository's Gitea issues, decides what to do about each thread as the Program Manager persona, and runs one worker agent per assignment that authors a change, runs the merge gate and opens a pull request. It reacts to issue creation and to comments; the assignment and all correspondence travel through the issue thread and the PR. It authenticates with an Anthropic subscription token. It never pushes to main and never merges. Three choices carry the design, with alternatives recorded in docs/plans/: - it POLLS rather than receiving webhooks (Gitea's webhook SSRF guard, lost deliveries, and no inbound reach needed at all); - it keeps NO state: the trigger is "the newest thing in this thread was not written by me", so the issue thread is the state — no PVC, no backup obligation; - the model holds NO tools: its reply is one JSON object this code validates, so nothing in the path executes text. The boundary is platform/kyverno/admission/pm-agent-job-shape.yaml (Enforce, failurePolicy: Fail), not the RBAC: Kubernetes places no `use` check on serviceAccountName, so "may create Jobs" is "may run arbitrary code as the namespace's most privileged identity". Six rules admit only the committed shape, and the worker identity is bound to nothing with no token mounted, so there is nothing to escalate to. 28/28 offline Kyverno assertions. Nothing has run: the image has never been built or pushed, and both the image digest and the two credentials are deliberate placeholders. See the handoff entry's "What I did NOT verify".

feat(unifi): SOPS-delivered UOS installer URL + per-boot install unit; correct the README
The operator's UOS bring-up becomes one field. apps/vms/unifi/unifi-uos-installer.sops.yaml
(SOPS/age, with a .example sibling per the crafty/headlamp convention) carries `installer-url`
and `console-password`. KubeVirt mounts it as a read-only iso9660 disk labelled UOSDATA and an
in-guest `uos-install.service` reads it on EVERY boot, so a later URL change needs only a commit
and a VM restart.
Mechanism verified against the DEPLOYED KubeVirt v1.9.0, not from memory:
* inline userData cap is exactly 2048 bytes — server-side dry-run apply accepted 2048 and
rejected 2049; the payload here is 1454.
* `cloudInitNoCloud.secretRef` and `secret.volumeLabel` both exist in the live CRD; the secret
disk + third disk were accepted by a server-side dry-run of the real manifest.
* the NoCloud seed's instance-id IS spec.template.spec.domain.firmware.uuid (read out of
noCloud.iso inside virt-launcher), stamped on the VM OBJECT, so it survives restarts. Editing
userData alone therefore changes NOTHING — cloud-init restores its cached datasource and skips
write_files/runcmd. The UUID is now pinned in git and bumped once so the new payload lands.
secretRef was deliberately NOT used for the whole cloud-config: it would put the shell in
ciphertext, out of reach of the L0 dollar-collapse guard, while Flux's envsubst still runs over
decrypted resources — the 2026-09-13 nextcloud-db shape. Script in plaintext, operator values in
SOPS. apps-vms had no `decryption` stanza (first encrypted content under apps/vms/), so one was
added to both overlays.
CORRECTION, and it is the headline: UNIFI OS SERVER IS ALREADY INSTALLED on the live guest. The
serial console log starts uosserver.service and uosserver-updater.service, and / is 6.3 GB of
40 GB used. The controller is unreachable because THE GUEST HAS NO IP: .status.interfaces shows
enp1s0 up with no address, and `ip neigh` in virt-launcher reports 10.0.2.2 FAILED. 11443/8443/
8080 and 22 all RST, from the pod IP and from 10.0.2.2 directly, so the VIP and the CNP are
exonerated. install-uos therefore bails out the moment systemd knows a uosserver.service —
without that guard this change would have reinstalled over a working controller.
There was also no way into the guest at all: no key, no password, and 22 is not a declared
masquerade port so SSH cannot work by construction. Hence console-password.
README corrections (it doubles as the rebuild runbook and was misdirecting):
* VIP 192.168.1.54 -> 192.168.2.21; pool 192.168.1.53-.60/.53 -> 192.168.2.20-.30 with the
Gateway on .20; device subnet 192.168.1.0/24 -> 192.168.2.0/24; node k3s-dev-1 -> k3s-prod-1.
All re-read live (pool blocks, cluster-vars, the Service EXTERNAL-IPs, LAN_CIDR).
* "UOS is NOT installed" -> it is; the real fault is the lost IP, with the evidence table.
* "apps-vms must NOT use postBuild.substituteFrom" -> it has since 2026-08-31 and the escape
contract is in force.
* "install-uos is no longer baked into the guest" -> it was baked in, and it was broken twice
over (an unverified firmware API, and no `install` subcommand).
* "SSH in, cloud-init installs the operator's key" -> it installs none, and 22 is not forwarded.
* externalTrafficPolicy Local -> Cluster (the 8-day outage fix already in 50-service-l4.yaml).
* 60 GB -> 40Gi (the DataVolume and the Bound PVC); "10 GB minimum" -> ~25 GB.
* userDataSecretRef -> the YAML key is `secretRef`.
* 90-httproute-optional.yaml referenced as if it existed; it was dropped.
Unattended install, honestly: Ubiquiti documents no silent flag, no answer file, no env vars.
`yes y | <installer> install` is the convergent community practice and is what ships here, with a
bare-invocation fallback. It has NOT been run end-to-end on our guest. The installer URL also
does not look signed or time-limited — it is account-derived and per-release; it is in SOPS
anyway, but nothing should depend on expiry.
The running VM was not touched: no restart, no migration, no re-import. Every cluster call was a
read or an explicit --dry-run=server; the live VM still carries firmware uuid ...c07 and the
34h-old virt-launcher pod is untouched. The change takes effect on the operator's next VM restart.

feat(env): BULK_NFS_SERVER — the one knob prod cannot answer yet, and why it is a placeholder
The bulk tier's PersistentVolumes need a server address, and there is no single correct one: the
two clusters sit on OPPOSITE SIDES of pfSense from the storage host, which has exactly one
interface (vmbr0 192.168.1.9/24, on pfSense's LAN).
dev 192.168.1.40/.41/.42 — the SAME segment. Reaches it directly, and already holds one NFS
export from it (/mnt/Storage/k8s-volumes, in the host's /etc/exports). Proven path, so
base's default is the dev value per this file's existing convention, and dev restates it.
prod 192.168.2.10/.11/.12 — pfSense's WAN. tcp/2049 does not traverse that today; 22 and 8006
answer only because pfSense port-forwards them via 192.168.2.102. Opening the storage path
is a PENDING operator decision whose two candidate outcomes give DIFFERENT values here:
192.168.2.102 (another port-forward) or 192.168.1.9 (a route). So prod holds
TBD-PROD-BULK-NFS-SERVER, this repo's established loud-placeholder convention.
Two findings recorded in the prod overlay because they change what the operator has to do:
* THE EXPORT'S CLIENT LIST IS THE SAME UNDER BOTH OUTCOMES. Measured today from this
workstation (192.168.2.132) through the existing port-forward: the storage host logged the
connection as coming from 192.168.2.132 — a WAN-side address — not from a pfSense LAN address
(`ss -tn` peer 192.168.2.132; the host's only route off-LAN is its default via 192.168.1.1).
pfSense DNATs WITHOUT source NAT, so the NFS server sees prod's REAL node addresses either
way. The `zfs set sharenfs=` work therefore does not have to wait for the routing decision.
* ONE PORT, NOT FOUR. The PVs mount nfsvers=4.1, and NFSv4 carries mount and lock in-protocol —
no rpcbind/111, mountd or statd. Whichever outcome is chosen, it opens tcp/2049 and nothing
else. NFSv3 would have needed four ports, three of them on ephemeral numbers.
*** AND ONE HONEST WEAKNESS, stated in the overlay where an operator will hit it. ***
Unlike the LAN knobs above it, this placeholder does NOT fail at apply time. A PV's
spec.nfs.server is an unvalidated string: the API server accepts it, the PV is created, and the
PVC BINDS (binding is pure control-plane). The failure appears only when a pod mounts —
MountVolume.SetUp "Failed to resolve server TBD-PROD-BULK-NFS-SERVER" — so plex, sonarr, radarr
and nextcloud would sit in ContainerCreating on prod. There is no CRD validation to lean on here,
so the guard has to be procedural: set the value before prod reconciles a revision carrying the
bulk volumes. Dev renders a working value and is where these manifests are meant to be proven.
Related finding, NOT fixed here because the file does not exist on main: the static guard this
convention is supposed to lean on, `bootstrap/standup.sh`'s `s3_is_placeholder` family, is absent
from main (it lives on unmerged prod branches), so
conformance/tests/l0-static/placeholder-guard-coupling exits 3 SKIPPED and nothing in the gate
currently refuses a placeholder-shaped overlay value. When standup.sh lands, its guard needs an
arm for this knob and a consumer that calls it — assertions (2) and (3) of that check then cover
this value automatically, since the detector's SEED vocabulary already matches "TBD".
Evidence: `kubectl kustomize clusters/dev` -> BULK_NFS_SERVER: 192.168.1.9;
`kubectl kustomize clusters/prod` -> BULK_NFS_SERVER: TBD-PROD-BULK-NFS-SERVER. Both exit 0.

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. Refs R-STATE-03, R-IDP-05, R-ENV-02, R-ENV-03. Co-Authored-By: Claude Opus 5 <[email protected]> |

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.

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.

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.
Serves: R-ENV-01, R-ENV-02, R-ENV-03, R-STATE-01, R-STATE-02, R-PLAT-01. Task: T-7.1.

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.

feat(backup): wire Velero + CNPG Barman to the live MinIO S3 target
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. Creds mirror platform/backup/minio-credentials.sops.yaml (scoped key k3s-backup), SOPS round-trip verified with the cluster age key. gate: green. Co-Authored-By: Claude Opus 4.8 <[email protected]> |

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.

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]> |

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).
- DESIGN-waves.md: wave table, topology, cutover runbook.

Phase-6: repoint Flux source to in-cluster Gitea
Cut the GitOps source over from the bootstrap host-Gitea (http://192.168.2.103:3000) to the now-healthy in-cluster Gitea at https://gitea.home.keithjackson.dev. Public repo, LE-prod wildcard cert publicly trusted, resolved in-cluster via coredns->Gateway, so no secretRef/caCert needed. Bootstrap host-Gitea retained (stopped) as a recovery path.

fix(kyverno): raise admission-controller resources + dev replicas 2 to stop fail-closed crashloop/502s
Admission controller was crashlooping (9 restarts/4h, exit 255, NOT OOM: live usage ~65Mi/384Mi limit, 7m cpu). Root cause: chart-default 100m CPU request starved the process under node contention, so client-go calls hit context-deadline-exceeded, leader-election lease renewal timed out, leadership was lost and the webhook server closed. Raise the CPU request to 250m (no CPU limit, to avoid CFS throttling) with modest memory headroom (256Mi/512Mi), and raise dev admission replicas 1->2 so a single fail-closed pod restart no longer 502s cluster-wide admission-gated writes.

fix(tls): switch dev to LE production issuer so in-cluster clients trust the wildcard cert
oauth2-proxy + Grafana OIDC discovery to keycloak.home.keithjackson.dev failed x509 'unknown authority' — the wildcard was LE-staging (untrusted). Prod issuer is registered + Ready; switching ACME_CLUSTER_ISSUER dev override staging->prod re-issues a publicly trusted cert. Needed for functional SSO (R-IDP) + R-TLS-01/03 'trusted'. NOTE: the trusted-tls conformance test embeds the LE-staging root and must be updated to the LE production root (ISRG Root X1) / system trust — follow-up.

feat(gitops): self-managing root Kustomization (fixes F-OPS1)
The on-cluster cluster-vars ConfigMap wasn't reconciled by Flux — this bootstrap
model had no Kustomization watching clusters/dev, so cluster-vars/overlay changes
needed a manual 'kubectl apply -k clusters/dev' (e.g. DNS_ZONE substituted empty
until re-applied). Add clusters/dev/sync.yaml: a self-managing root Kustomization
(flux2 gotk-sync pattern, name flux-system) that reconciles ./clusters/dev from git
— cluster-vars, the GitRepository, platform/platform-config/apps, and itself. A git
push now suffices. Bootstrap unchanged ('kubectl apply -k clusters/dev' creates it
once). Verified: dev build contains all 6 objects (root + existing), prod unaffected.

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.

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.

Phase 1: host Gitea as the bootstrap GitOps source (resolves source-URL)
Run a single Gitea container on the host (bootstrap/gitea/), outside the cluster, while the cluster is built; Flux pulls this repo from it over the k3s-dev NAT gateway (http://10.73.0.1:3000/Home-Network/home-network-k3s-impl.git, public repo => no creds, NAT-only). Wired the flux-system GitRepository url in clusters/dev. Migrates to in-cluster Gitea in Phase 6. Pins confirmed. Author-only; gate PASS.

Phase 1 (author-only): Flux + SOPS bootstrap + interface wiring (T-1.4)
bootstrap/sops (age-keygen refusing in-repo, .sops.yaml, install-age-key.sh glue installing the sops-age Secret) + bootstrap/flux (bootstrap.sh: flux install -> apply -k clusters/dev; decryption/url patches). PM wiring: place .sops.yaml at repo root (SOPS walks to root); inline the 3 flux patches into clusters/dev (avoids kustomize ../ load-restriction). clusters/dev builds with decryption enabled; full CI gate PASS. No key material; nothing executed. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> |
