docs(vpn-ingress): withdraw the L2-lease diagnosis — it was falsified by measurement
The claim this branch originally shipped (a node cannot reach a LoadBalancer VIP whose Cilium L2 announcement lease it holds, so VPN clients inherit that via hostNetwork MASQUERADE) is FALSE. Re-measured with all 8 l2announce leases on k3s-prod-1: ip neigh show 192.168.2.20 -> INCOMPLETE (cause present) nc -z 192.168.2.20 443 -> OK curl --resolve ... :192.168.2.20 -> 200 in 25ms (effect absent) Cause present, effect absent. prod-2 and prod-3 return the same 200. Why it was never going to bite: cilium-dbg status shows `KubeProxyReplacement: True [eno1 ..., wg0 10.90.0.1]` and `Masquerading: BPF [eno1, wg0]` -- Cilium's LB datapath is attached to wg0, so a client packet for a VIP is DNAT'd in BPF BEFORE any neighbour lookup, and the Gateway backend is a node-local Envoy socket anyway. The methodological error, which is the part worth keeping: every probe was run from the wireguard pod on the grounds that sharing the host netns made it "the path a MASQUERADEd client takes". False. A MASQUERADEd client is FORWARDED (netfilter FORWARD + routing); a probe started in the pod is SOCKET-ORIGINATED (Cilium socket-LB). Different hooks -- sharing a namespace is not sharing a hook. The `curl --interface wg0` control cited to rule out a host-netns artefact fails on ALL THREE nodes including ones whose ARP resolves, so it discriminated nothing. A raw-IP `curl -k https://192.168.2.20/` returning rc=35 is missing SNI, not unreachability. Also corrected: new-peer.sh emits AllowedIPs = 0.0.0.0/0 (FULL tunnel) by default; `--split` is the opt-in. An earlier reading had the branches backwards. All code is withdrawn -- the nodeSelector exclusion, the node_baseline label tasks, both alerts, the promtool tests and the KSM allowlist entry are gone. Net change is three documentation files, purely additive (356 insertions, 0 deletions), recording what was measured so the next person does not redo it. The reported internet-routing problem is NOT diagnosed here: no client had connected since the power-cycle (no peer endpoint, 0 packets through FORWARD and MASQUERADE), so the forwarded path was unmeasurable.

fix(conformance): one regex made the merge gate take 28 minutes instead of 2
ha-control-plane-as-code/check.sh had: re.search(r"--server https://.*?\n(?:.*\n){0,10}?\s*when:...'secondary'", K3S_TEXT, re.S) With re.S every `.` matches newlines, so `.*?` and the nested `(?:.*\n){0,10}?` can each consume the whole document -- nested unbounded repetition, which backtracks exponentially on a failed or late match. MEASURED in CI via `docker top` on the live job container: python3 at 19:54 of CPU time, which is essentially the entire ~28 minute gate. Localised to the exact line by extracting the inline python and running it under faulthandler.dump_traceback_later, which named re/__init__.py:177 in search from this call -- not inferred from reading. Replaced `.` with `[^\n]*` and dropped re.S, so the {0,10} is a real ten-line window with nothing to backtrack into. On the real input (22,179 chars): 0.2 ms, match still found. Whole check: 0.199s, rc 0, 115 assertions, identical success message. WHY IT SURFACED NOW, AND IT WAS MINE: K3S_TEXT is every *.yml in roles/k3s_server concatenated. The regex was latent for as long as it existed; PR #71 added ~100 lines to that role (kubelet graceful-shutdown config), growing the input past the point where exponential backtracking stopped being survivable. WHY ONLY infra/** WAS SLOW: touched-requirements.sh maps infra/* to R-ENV-01, so the L0 run becomes --include-scope whole-repo --requirements R-ENV-01, which selects this whole-repo check. Doc/platform changes never did -- #69 1m55s and #72 1m53s stayed fast while #71 27m44s, the #73 merge 27m46s and #75 all ran ~28m. The pattern is unique in the repo (grep over all l0-static check.sh files). Not re-timed in CI post-fix; this PR's own run is the first datapoint.

fix(unattended-upgrades): Debian has no reboot-sentinel package, so ship the writer
The first real run failed on all three nodes: fatal: [k3s-prod-1]: "No package matching 'update-notifier-common' is available" update-notifier-common is an UBUNTU package and does not exist in Debian -- `apt-cache policy` returns Candidate: (none) on trixie. The role asserted it "owns the hook that creates /var/run/reboot-required", which is true on Ubuntu and false here, so the role could never have worked. Three further measurements settled the replacement: notify-reboot-required is absent; NO linux-image-* postinst references it (invoking it is an Ubuntu patch, so dropping a script at that path would never be called); and no hook under apt.conf.d or /etc/kernel mentions reboot-required. Debian trixie ships no mechanism at all. So the role now provides it: * /usr/local/sbin/k3s-notify-reboot-required -- touches the sentinel when the running kernel is not the newest installed, using `linux-version` (from linux-base, a dependency of every linux-image, measured present) because kernel version ordering is not string ordering. * /etc/apt/apt.conf.d/99-k3s-reboot-required -- DPkg::Post-Invoke, `|| true` so it can never abort an apt transaction. /run is tmpfs (measured), so the sentinel self-clears on boot; no cleanup task. The verify assert was ALSO weaker than it looked: a `find` glob for *update-notifier* / *unattended-upgrades* under apt.conf.d would have matched Debian's own unattended-upgrades conffile and reported "writer present" while none existed. It now stats the two exact paths this role owns and requires the script to be executable. Newly verified: the script ran on prod-1 as unprivileged k3s under sh -x -- running=newest=7.1.8+deb13-amd64, took the equal branch, exited 0, wrote nothing. Correct. sh -n and bash -n clean. Still unverified: the WRITING half never executes while running == newest, so the sentinel has not been seen created and kured has not been seen react. The honest test is the next kernel upgrade.

fix(coredns): hold in-cluster DNS at 2 replicas via an HPA, because k3s owns the Deployment
MEASURED on prod 2026-10-18: kube-system/coredns had replicas: 1. In-cluster DNS was a single pod on a single node, so draining or rebooting that node was a CLUSTER-WIDE in-cluster DNS outage until the pod rescheduled -- every Service lookup, every CNPG replica finding its primary, every operator addressing the API by name. It was invisible because 1/1 Ready looks healthy. It is urgent rather than latent now: the scheduled reboot automation on feat/automated-upgrades drains and reboots one node at a time, unattended, overnight -- turning a single point of failure into a recurring one. WHY AN HPA AND NOT replicas: 2 -- the whole decision. k3s OWNS the coredns Deployment: AddOn/coredns, source /data/k3s/server/manifests/coredns.yaml, managedFields managers deploy@k3s-prod-1 + k3s, objectset.rio.cattle.io/hash label. k3s re-stages its bundled manifests on startup, so replicas: 2 written there -- or a kubectl scale -- is reverted on the next restart or upgrade. Rejected alternatives: * coredns.yaml.skip + our own templated copy (the roles/kube_vip pattern). Deterministic, but takes ownership of coredns from k3s permanently so k3s upgrades stop updating it. Too high a price for a replica count. * A Flux patch of the Deployment. Rejected outright: Flux and k3s's deploy controller would both own one object and fight -- the default-deny NetworkPolicy drift-loop shape (~2500 events/10min) this cluster already hit. An HPA is a separate object k3s does not own, driving /scale rather than the Deployment spec, so there is no shared-ownership fight; if k3s re-stages replicas: 1 it is re-asserted within a reconcile. Disclosed cost: a brief window at 1 replica after a k3s restart. It is a FLOOR-HOLDER, not an autoscaler -- the CPU metric exists only so the autoscaling/v2 object is valid. Measured: 5m/4m against a 100m request (~5%), so the 80% target is never approached. scaleDown stabilization 600s because DNS is the worst thing to flap; scaleUp immediate, since that restores redundancy. The kustomization edit is ADDITIVE: platform/coredns/ already existed and holds the coredns-custom split-horizon ConfigMap (R-DNS-01/03), which is untouched. UNAPPLIED. The HPA has never run, and the claim that k3s reverts replicas on restart is reasoned, not observed. After merge check `describe hpa coredns` for ScalingActive=True -- an inert HPA looks identical to a working one because the hand scale already left 2 replicas. See the handoff entry.

feat(upgrades): automated OS reboots (kured) + security-only unattended-upgrades, and give Renovate a runner
Two halves of one repeatable upgrade process. Neither works alone. (a) OS upgrades and reboots platform/kured/ — Kubernetes Reboot Daemon, chart 6.1.0/app 1.23.0, in its own Flux Kustomization (dependsOn platform, wait:true). NOT in platform/kustomization.yaml: that tier gates platform-config and every apps wave, so a wedged reboot daemon there could stall every application. A component added to make maintenance safer must not be able to cause an outage. infra/ansible/roles/unattended_upgrades/ — new role (node_baseline is touched by other open branches, and this is a different lifecycle), enabled for prod in group_vars. The human gate is the SENTINEL, which is how this honours node_baseline's "IT DOES NOT REBOOT" (k3s-prod-2 hung on a warm reboot 2026-09-03) and cluster-upgrade-plan.md's rejection of automating away the gate between nodes: u-u is security-only with the kernel blacklisted, so it essentially never writes /var/run/reboot-required. That file appears when an operator deliberately runs node-baseline.yml --tags kernel. kured then does only the mechanical half, including the ordering rule node_baseline has to shout. Quorum: concurrent reboots are structurally impossible, not merely unlikely. concurrency:1 plus kured's single lock annotation (API-server optimistic concurrency), and lockTtl:0 — an expiring lock is exactly the 3-node etcd catastrophe, so a hung node holds it forever and nothing cascades. Longhorn: measured 25 volumes x 3 replicas, hard anti-affinity, 600s replenishment wait, serialized rebuild — so every drain degrades ALL volumes to 2/3 and the inter-node gate must be volume robustness, not pod readiness. Doubled: lockReleaseDelay 30m (unconditional) plus kured's Prometheus alert gate (semantic). alertFilterMatchOnly:true is load-bearing — the flag inverts the regexp's meaning, and under the chart default kured would have been blocked on day one by the five alerts measured firing with no end in sight, and never rebooted anything. Kernel floor (kernel >= 6.13, EFI memattr): excluded TWICE. The running kernel comes from o=Debian Backports, which is not an allowed origin, so u-u cannot see a kernel upgrade; and ^linux- is blacklisted anyway so widening origins later cannot re-arm it. Asserted against apt-config dump, not against the file just written. 6.12 kernels are still installed and bootable on all three nodes, and nothing was held. Closes a silent no-op: update-notifier-common was absent on all three nodes, so NOTHING could create the sentinel. kured alone would have idled forever at 1/1 Running. platform/kured/alerts.yaml — three rules over kured's only metric, with a companion promtool suite pinning each both ways, plus runbooks/node-reboot-automation.md. Window is DAILY 03:00-06:00 because a weekly one forces for:8d, longer than this cluster's 7d Prometheus retention. (b) Image/dependency automation Renovate was aspirational: renovate.json present and complete, with no workflow, no in-cluster workload, and its docker+kubernetes managers disabled — so every plain image: tag was maintained by nothing while seven files claimed otherwise. .gitea/workflows/renovate.yaml — scheduled daily, dry_run default true for a safe first run, and a preflight that FAILS (not skips) without RENOVATE_TOKEN, because a skipped Gitea job reports success and that is how this stayed inert. Renovate now owns both halves; Flux image-automation is formally closed: it pushes commits rather than opening PRs (bypassing CLAUDE.md §1), and it cannot work here anyway — main is protected user_can_push:false and the flux-system GitRepository has no secretRef. Its controllers are installed and have idled 43 days with zero CRs. conformance/: +34/-0, one new SCRAPE_OWNERS entry claiming kured_. Weakens nothing; tightens the check for this component (requires service.create+metrics.create, both chart-default false, plus a companion NetworkPolicy requirement). Required because assertion (3) fails an alert over an unclaimed metric and KNOWN_UNWIRED_METRICS is shrink-only. Sensitive paths touched: clusters/**, conformance/**, .gitea/** — needs a non-author approving review; /approve-override deliberately NOT posted. NOT verified: no OS upgrade run, no node rebooted, no lock observed, the Ansible role never executed, and whether CNPG switches its primary on a drain-induced eviction (the most likely way the first real reboot fails).

feat(keycloak): declare passkey (WebAuthn passwordless) login for the homelab realm
Adds the realm's WebAuthn Passwordless policy and restructures the browser-mfa
flow so a passkey is an ALTERNATIVE beside the password form. Additive and
optional by design: this IdP gates every SSO app plus kubectl, so a mandatory
passkey flow that misfires is a total lock-out. Enrolment is not forced.
Policy: RP ID is ${BASE_DOMAIN} (not the keycloak host) because a passkey's RP ID
is fixed at enrolment and must not be bound to a name that can move; resident key
required (a non-discoverable credential is a second factor, not a passkey); user
verification required (without it, possession alone is a complete login).
Flow: auth-username-password-form is split into auth-username-form +
auth-password-form, because the server must know who is logging in before it can
decide whether a passkey exists. Conditional OTP for platform-admins is relocated
intact onto the password branch only — a UV-required passkey is already two
phishing-resistant factors.
No requiredActions block is declared, deliberately: Keycloak 26.0.6 treats
requiredActions as REPLACE not merge, so declaring one would delete the default
set including CONFIGURE_TOTP and lock every platform-admin out of the OTP step
this flow still enforces. webauthn-register-passwordless is already registered
enabled-but-not-default by Keycloak's own defaults.
UNAPPLIED: the realm import is a one-shot resting at Done=True/Started=False, so
this reaches the live realm never. See the handoff entry and the README section.

fix(oauth2-proxy): gate startup on Keycloak discovery, or a cold boot CrashLoops the proxy
Exposed by the 2026-10-17 whole-cluster shutdown. oauth2-proxy performs OIDC
discovery ONCE at startup and exits 1 if it fails. On a cold boot Keycloak is
not serving yet, the shared Gateway answers 503, and the proxy dies:
[provider.go:55] Performing OIDC Discovery...
[main.go:73] ERROR: Failed to initialise OAuth2 Proxy: ... failed to discover
OIDC configuration: unexpected status "503": no healthy upstream
It then sits in exponential CrashLoopBackOff long after Keycloak is healthy --
one replica was still down minutes later and only a manual pod delete cleared
it. There is no retry flag, a readinessProbe cannot help (the container is
already dead), and CrashLoopBackOff backoff is not tunable per-pod.
Add an extraInitContainers gate (wait-for-idp) that polls the discovery doc
until it answers. A pod in Init accrues no CrashLoopBackOff backoff and retries
promptly. BOUNDED and FAILS OPEN: after ~5m it starts the proxy anyway, so the
worst case is exactly today's behaviour and never something new.
extraInitContainers is the chart's OWN hook for this -- its commented example is
literally `- name: wait-for-idp` -- and the key was CONFIRMED against the pinned
chart (helm show values, 10.7.1) rather than assumed, because a wrong Helm values
key is silently ignored. No new base image: the chart already runs an alpine init
container for its built-in waitForRedis gate; pinned to 3.22 (verified upstream)
rather than the chart's `latest`.
Rejected: Flux postRenderers (no precedent in this tree, and the chart has a
hook); --skip-oidc-discovery (removes the fetch entirely, but needs four
hardcoded endpoints and I could not verify lazy-JWKS offline -- this component
gates SSO for seven apps, so the additive option wins).
Shell vars are written BARE with no braced form: platform declares
postBuild.substituteFrom, and envsubst would blank a braced shell variable and
silently break the loop. Same convention as the gitea/nextcloud OIDC hooks.
UNAPPLIED; the init container has never run, and the race was not re-created to
prove the fix. Check the init container's log on first apply. See the handoff.

feat(shutdown): configure graceful node shutdown, and never scale a Delete-policy StatefulSet
All three nodes had to be powered off to move them onto a UPS, and there was NO procedure: infra/cluster.sh stop is virsh-based and only ever applied to the decommissioned dev cluster. The sequence was improvised live. Two defects came out of doing it. 1. GRACEFUL NODE SHUTDOWN WAS UNCONFIGURED ON EVERY PROD NODE. No shutdownGracePeriod anywhere in infra/ansible/, so `shutdown -h` stopped k3s, containerd went with it, and every pod was SIGKILLed where it stood -- 9 CNPG instances mid-checkpoint, the UniFi VM, 25 attached Longhorn volumes. roles/k3s_server now sets kubelet-arg shutdown-grace-period=90s and shutdown-grace-period-critical-pods=20s. The half that silently defeats the other half: this is enforced by LOGIND, not the kubelet. The kubelet holds an inhibitor DELAY lock and systemd waits at most InhibitDelayMaxSec -- DEFAULT 5 SECONDS -- then proceeds regardless, truncating the drain with no error. The role ships a logind.conf.d drop-in (120) and ASSERTS cap >= grace period, because the failure is invisible. 2. SCALING A StatefulSet TO 0 DELETED ITS PVC AND VOLUME. monitoring/loki carries persistentVolumeClaimRetentionPolicy whenScaled: Delete, so the quiesce destroyed storage-loki-0 outright. Loki stores type: filesystem, so that PVC was the only copy; 72h retention bounded the loss, the mechanism does not. Symptom was the volume count going 25 -> 24, first misread as a miscount. Repaired: scale back to the declared 1 recreated the PVC and loki-0 is 2/2 Running. New infra/maintenance/quiesce.sh (quiesce|resume|status) encodes the sequence that worked and REFUSES to scale any whenScaled: Delete StatefulSet -- it stays running, its volume hard-detaches, and it rebuilds on restart. A rebuild beats a deletion. Discovery is computed from the live cluster, so a newly onboarded service needs no edit here. runbooks/cluster-maintenance-shutdown.md is the operator page: order in both directions, TrueNAS-after-nodes (hard NFS mount wedges kubelet), the un-hibernate-Postgres step Flux will NOT do for you, and a "looks broken but is fine" section separating the 4/19 Flux cascade, the degraded-and-rebuilding volume and the self-recovering keycloak-operator from the one thing that needs a human (a stuck oauth2-proxy replica). THE KUBELET CHANGE HAS NEVER BEEN APPLIED OR TESTED -- it needs a rolling k3s restart, which is an operator action. Review config.yaml's kubelet-arg before applying: a bad config.yaml is how k3s fails to come up. See the handoff entry. Co-Authored-By: Claude Opus 5 (1M context) <[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): content-hash the peer register, or a merged peer never reaches the tunnel
The operator enrolled a phone, merged the peer, and `wg show` listed none. Measured on prod 2026-10-06 with the peer already on main: live wg-peers ConfigMap, active AllowedIPs .. 0 DaemonSet volume reference ................. configMap.name: wg-peers (FIXED) DaemonSet generation/observedGeneration .... 1 / 1 (never rolled) init container, all three pods ............. "0 peer(s)" Part of it was just the 10m reconcile interval. The defect is the fixed name: Flux updates a fixed-name ConfigMap IN PLACE, so the pod template is byte-identical, so no rollout is triggered -- and the init container assembles wg0.conf ONCE at pod start into a tmpfs, so the running tunnel keeps the old peer list indefinitely. Adding or revoking a peer had no effect until something unrelated restarted the pods. For a REVOCATION that is a security defect, not an inconvenience: delete a stanza, see a green PR, device keeps working. The runbook and README both claimed "PR -> merge -> Flux rolls the DaemonSet". Never true. And this repo already documents the fix, in a file I had read -- runbooks/kustomization.yaml: "The generated name carries kustomize's content hash, so editing any runbook rolls the server automatically and a stale projection is impossible." So: peers.yaml (inline ConfigMap) -> peers.conf (plain file) + a configMapGenerator. The operator's enrolled peer is carried across verbatim. Every line is WireGuard config and `#` is a legal comment there, so the documentation now lives inside the file that is actually mounted. `namespace: vpn-ingress` on the kustomization is REQUIRED, not tidiness: a generated ConfigMap inherits no namespace, everything else here declares vpn-ingress, and kustomize's nameReference will not rewrite across a namespace boundary -- without it the build mounts the unhashed name and the pods wedge on a missing volume. Caught only by building the output and reading the volumes. new-peer.sh: PEERS_FILE repointed, and a missing register is now FATAL rather than skipped -- the old `[ -r "$PEERS_FILE" ] && grep ...` guard meant that after the rename the only symptom would have been duplicate detection quietly never firing again. Stale peers.yaml references swept from six files including the script's own user-facing output. Verified: the DaemonSet now mounts wg-peers-m9kcckcb5t; the hash tracks content (edit -> dgg7ht9c74 -> restore -> m9kcckcb5t); the enrolled peer is byte-identical to main's; and `new-peer.sh dupe 2` is now correctly refused by the operator's real allocation. No sensitive paths; merges on a green gate. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

fix(vpn-ingress): new-peer.sh counted its own commented-out example as an allocated address
The first real enrolment failed:
$ ./infra/vpn-ingress/new-peer.sh keith-phone 2
new-peer.sh: 10.90.0.2/32 is already allocated ... Pick another octet.
Nothing was allocated -- peers.yaml had zero peers, as the pod's init
container reported (`0 peer(s)`). The duplicate-address check grepped the
whole file, and peers.yaml line 66 is a COMMENTED-OUT example stanza I wrote
containing literally `# AllowedIPs = 10.90.0.2/32`. So .2 -- the first
address anyone would ask for, and the one my own runbook uses as its example
-- was permanently un-allocatable, with a message asserting the opposite of
the truth.
Fixed on both sides, because either alone leaves the trap half-set:
* the check strips comment lines before matching, which is the correct
predicate rather than a patch: a real stanza's AllowedIPs line is never
commented, while the template and every peer's `# <name> — <owner>` label
always are.
* the example now uses placeholders that cannot match anything real
(`10.90.0.<octet>/32`, `<device-name>`), so a future grep cannot be fooled
by it either.
The bug class is worth naming: a documentation example that is byte-identical
to real data will eventually be parsed as real data. This is its third
instance in this component -- flux-postbuild-substitution flagged a `${...}`
written inside a comment explaining that hazard, and no-plaintext-secrets
flagged the .sops.yaml.example because a kustomization named it in a comment.
Make examples structurally unmatchable, not merely commented out.
Verified by running it: .2 now renders a profile (via the real
`sops -d | wg pubkey` path, which this also proves against the operator's
actual key for the first time), and an uncommented duplicate stanza is still
correctly refused.
No sensitive paths; merges on a green gate.

[#] sysctl -q -w net.ipv4.ip_forward=1
sysctl: permission denied on key "net.ipv4.ip_forward"
[#] ip link delete dev wg0
**** Tunnel failed, will stop all others! ****
Not a missing capability: with hostNetwork the runtime mounts /proc/sys
READ-ONLY (confirmed in the pod's /proc/mounts), because those sysctls are the
HOST's globals. CAP_NET_ADMIN cannot lift a read-only mount, so the write can
never succeed here -- and wg-quick treats a failed PostUp as fatal, so it
deleted the interface it had just built.
The line was never needed. node_baseline already sets ip_forward=1, and reading
it from the pod returns 1. My header comment said exactly that ("so no pod
sysctl is needed") and then emitted the sysctl anyway, justified as "re-asserted
so this component does not silently depend on another role's sysctl file". That
defensive re-assertion is the entire outage. In a hostNetwork pod: VERIFY host
state, never write it.
Replaced with a read in the init container -- `grep -qx 1
/proc/sys/net/ipv4/ip_forward` -- failing closed with a message naming the
node_baseline role. Still fail-closed on purpose: a tunnel that comes up unable
to forward satisfies every probe here and silently drops all client traffic.
Also documents, in the manifest and the runbook, that the image's `chown:
Operation not permitted` run and its "we will not provide support for it"
warning are expected and harmless -- capabilities are dropped to NET_ADMIN so
its s6 init has no CAP_CHOWN, /config is a writable tmpfs, everything runs as
root, and wg-quick proceeds (it did; the failure was 30 lines later).
Three other unknowns closed by the same reconcile, now recorded in the README:
the kernel module reaches the pod (ip link add type wireguard works, no
CAP_SYS_MODULE needed); allowPrivilegeEscalation:false does NOT break the s6
init; and the image's iptables is nf_tables (xtables-nft-multi) matching Debian
13, which closes the worst documented fear -- rules landing in a table the
kernel never consults.
No sensitive paths; merges on a green gate with no override.

fix(devcontainer): bake wg + qrencode into the image instead of splitting the VPN procedure across host and container
Operator correction: "sop, wg, and any other tool requirement is supposed to be
baked into the devcontainer."
My previous commit discovered that `wg` existed only on the host, `sops` only in
the container, and `qrencode` on neither -- and fixed it the wrong way, by
splitting every step of the key procedure across the boundary and telling the
operator to `dnf install qrencode` on their workstation. That breaks CLAUDE.md §5
and the devcontainer README's "Don't install the toolchain on the host", produces
a procedure that cannot be reproduced in CI, and is miserable to follow.
wireguard-tools + qrencode are now distro packages in the Containerfile. Both are
in Fedora 44's repos (wireguard-tools 1.0.20260223 -- the same upstream version as
the image this component runs -- and qrencode 4.1.1), unpinned like every other
dnf package there: the pinned thing is the Fedora base, and neither is a gate tool
whose version changes what green means.
Three things got SIMPLER rather than merely relocated, which is the tell that the
rule was right:
* Step 2 is one pipeline in one shell -- `sops set ... "$(wg genkey)"` writes the
key straight into the already-encrypted document. No staged copy in .cache, no
`*.key`-suffix warning, no sha256 comparison to prove the right bytes landed.
* new-peer.sh derives the server public key from wg-server-key.sops.yaml itself
(`sops -d --extract | wg pubkey`), so there is no local key copy to keep in
step with the encrypted one, and no magic host path it must live at.
* `.cache/` is gitignored at the repo root (mirroring infra/ansible/.gitignore),
giving the container a persistent non-committable scratch dir. new-peer.sh
writes profiles to .cache/wg-peers/ -- necessary because the repo bind-mount is
the container's only persistent read-write mount, so a profile in /tmp there is
gone before it can reach a desktop. Its blanket "refuse to write inside the
checkout" guard is now a `git check-ignore` test of the real property.
Verified by execution, not reasoning: the image rebuilds; wg/qrencode/sops all
resolve in it; `sops -d | wg pubkey` runs in one shell; new-peer.sh refuses the
REPLACE-ME placeholder with an actionable message; and a full run with a throwaway
server key renders a correct profile at 0600 under a 0700 gitignored dir, prints
the QR, and refuses a non-ignored destination inside the repo.

docs(node): name the exact Ansible command that applies the pin, not 'run the play'
Node configuration in this project is Ansible's — declared in the inventory, reviewed,
version-controlled — and for prod it is the ONLY surface: infra/PROD-PROVISIONING.md
records prod as 3x bare metal with the dev OpenTofu -> Proxmox -> cloud-init path
explicitly not applying, so there is no tofu/cloud-init half to keep in parity for an
/etc/hosts pin.
The pin was already in the right place; what the docs lacked was the command. All four
places now carry the scoped, idempotent one:
cd infra/ansible && ansible-playbook playbooks/node-baseline.yml \
-e k3s_hosts=k3s_prod --tags hosts
--tags hosts runs ONLY the /etc/hosts task, so applying this pin cannot drift any other
baseline setting.
Also verified the mechanism is not inert, which is the failure mode this repo keeps
meeting: roles/node_baseline/tasks/main.yml renders node_baseline_hosts_pins into a marked
blockinfile with backup: true, and state: absent when the list empties — so a removed
entry really does leave the node.

fix(node): pin gitea to the Gateway VIP — containerd was resolving it to the non-hairpinned WAN
The pm-agent image pull failed TLS verification, and the previous entry on this branch
recorded it honestly as not diagnosed. Diagnosed now, and it is not about the image.
containerd pulls as a NODE process, so it resolves through node_baseline_dns_servers (the
LAN gateway, deliberately not PiHole) and gets the public answer: a CNAME to
wan.home.keithjackson.dev -> 136.51.115.252, measured via both 1.1.1.1 and 8.8.8.8. This
router does not hairpin, so WAN:443 answers with its own placeholder certificate —
measured with the right SNI from the workstation:
subject=C=ZZ, ST=Somewhere, L=Unknown, O=%D342e7e6b, CN=%D
No extensions in certificate
No extensions means no subjectAltName, which is exactly 'certificate is not valid for any
names'. Meanwhile 192.168.2.20 IS the shared Gateway's VIP and its https listener serves
the real Let's Encrypt *.home.keithjackson.dev. The Gateway, the wildcard cert and the
digest were never implicated — only the node's answer.
This file already documents the identical failure for the Keycloak issuer, measured from
k3s-prod-2/-3 on 2026-10-03 (curl exit 60, ssl_verify_result=18), and already carries the
mechanism that fixes it. gitea is simply the second node process to need it; containerd is
a node process and nobody had added it. An operator must run the node_baseline play.
Also records, where an operator reads them, that the agent authenticates to Gitea with a
local account and a scoped PAT by decision — and why the federated alternative is not
merely unchosen but unavailable: Gitea implements only the Authorization Code Grant and
validates no third-party OIDC token, so a Keycloak service-account token cannot
authenticate to its API or to git-over-HTTP.

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.

fix(pm-agent): the agent is IN the cluster — one git host, the cluster-local service name
An in-cluster consumer reaches a service by its *.svc.cluster.local name, which is by design a different path from how a client outside the cluster reaches the same service. pm-worker's host allowlist accepted TWO values: the cluster-local name and the external hostname gitea.home.keithjackson.dev. The second is removed. It was never needed — nothing sets it — it would route in-cluster traffic out through the Gateway and back for no reason, and as an ACCEPTED value it widened the allowlist to a host reachable over the namespace's world:443 egress rule, which is precisely the injection shape the allowlist exists to refuse. probe-validation.sh now pins that: 20 refusals, including the external hostname, the cluster-local name over https, and the cluster-local name on the wrong port. Also corrects a remark in the handoff entry: I cited cluster-vars' GATEWAY_VIP (192.168.1.53) as suspicious next to the nodes' 192.168.2.x. That was noise — those base cluster-vars values are dev-era leftovers for a decommissioned cluster and say nothing about prod. None of the measured facts depended on it.

docs(pm-agent): the registry cannot be pulled from yet — name both prerequisites where the operator reads them
pm-agent reconciled exactly as designed after #57: Flux applied main@sha1:95597bd to platform-config, pm-agent and apps-wave-0 (all Ready), the ClusterPolicy pm-agent-job-shape is live with Enforce + failurePolicy Fail and all six rules, SOPS decryption works through the new overlay patch (checked by key names and value lengths, never values), and pm-agent-worker really is bound to nothing. Measuring it turned up two prerequisites for the NEXT operator step that nothing in this repository declares, and that #57's handoff could not have known — it listed the image pull as unverified, and that is exactly where it bit: - the nodes cannot verify the registry's TLS certificate (containerd: 'x509: certificate is not valid for any names'), while the same name serves a healthy Let's Encrypt wildcard from the LAN. A correct digest fails identically; - an unauthenticated client gets nothing from this Gitea's registry (its anonymous token carries no access scope) and no imagePullSecret exists anywhere in the tree. Not specific to pm-agent: conformance-runner shares the registry path and has never been pulled either. The dispatcher is the first workload in the cluster ever to reference it. Documentation only — no manifest, no policy, no code. Both fixes need an operator action and one of them is a posture decision, so the docs present both rather than pick.

fix(runbooks): vpn-remote-access step 1 named a nonexistent script; step 2 cited the wrong gitignore rule
Both reported by the operator on first use of the runbook merged in #55.
Step 1 said `cd infra/ansible && ./site.sh --tags system --limit k3s_prod`.
There is no site.sh anywhere in this repo. It was wrong four ways at once:
this repo drives Ansible with `ansible-playbook <playbook>` and never a
wrapper (playbooks/site.yml is the full bring-up chain, not this); the module
work is in playbooks/node-baseline.yml; targeting here is `-e k3s_hosts=...`,
not `--limit`; and Ansible exists only in the pinned toolbox, with ansible.cfg
read only from infra/ansible. Replaced with the real command plus why
`-e k3s_hosts=k3s_prod` matters (the default group is decommissioned dev) and
why `--tags system` must never be dropped (an untagged run also executes the
`disks` tasks, which assert on prod's deliberate placeholder devices).
Step 2 told the operator to stage the server key at /work/.cache/server.key
"inside the repo's gitignored cache". .cache/ is NOT gitignored -- the file was
ignored only incidentally by `*.key` (.gitignore:11). So the path was safe for
a reason I had not identified, and renaming it (server.pem, wg-server) would
have left a committable WireGuard private key in the checkout, which
no-plaintext-secrets does not recognise. The step now names the real rule,
marks the suffix as the load-bearing part, and gives a check-ignore
verification to run before trusting it.
Docs only -- no manifest and no behaviour change. Touches no sensitive path.
Also records the post-merge measurements for #55, whose own entry predates the
merge: Flux applied

docs(pm-agent): correct the handoff — a STALE approval still satisfies the gate
I recorded that merging main in would dismiss the operator's approval and that approval-policy would therefore go red until they re-approved. Measured: wrong. dismiss_stale_approvals is true, so the review did go stale — but ci/approval-policy.sh selects on .state == "APPROVED" and a non-author login and reads nothing about staleness, and required_approvals is 0 so Gitea never required one either. CI run #257 on the merged head: "approved by 'jakman85' (author 'gitea-admin') — sensitive change is human-reviewed", approval-policy pass, gitea-settings pass, required check green, PR mergeable. The 'push again and you must override again' rule applies to the /approve-override directive, which IS staleness-checked against the head commit — not to a review.

docs(pm-agent): CLAUDE.md §0 is already satisfied in a worker — tell it not to make a worktree
PR #56 added §0 (work in your own worktree, never the shared checkout) while this branch was open. A worker agent reads CLAUDE.md first, and §0's instruction is to create a git worktree outside the shared checkout — which does not exist in a worker's container. It holds a fresh clone of its own, made for one assignment and thrown away with the pod, which is what §0 is actually asking for. A worker that obeyed §0 literally would 'git worktree add', edit somewhere the wrapper that started it does not look, and have its work committed by nobody while the issue got a 'changed nothing' report. worker-rules.md now says §0 is satisfied and not to do that. Also records in the handoff entry: the merge and its one conflict, and that this push dismisses the operator's approving review — measured, dismiss_stale_approvals=true — so the approval-policy stage needs them to re-approve. That is theirs to do, not an agent's. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

test(pm-agent): a committed negative-path probe for the worker's input guards
pm-worker's command is pinned by admission with no args, so everything a caller could influence arrives in the environment — and the guards at the top of that script are what stand between an injected variable and a clone from the wrong host or a push to the wrong ref. Nothing exercised them, which makes them a claim rather than a control. probe-validation.sh asserts 17 refusals, each on BOTH a non-zero exit and the specific message, so a guard that stopped firing cannot pass by failing somewhere else. It covers a redirected git host, a real and reachable WRONG one (the egress policy permits tcp/443, so that case is not hypothetical), the right host with a smuggled path, 'main' and five other bad branch shapes, a malformed owner/repo, a bad mode, a bad issue number, and each missing credential. build-image.sh runs it inside the built image too. Writing it found three things: - the PM_BRANCH != main guard is unreachable while the pattern check above it holds, so the comment claiming it as the defence was wrong about which line does the work. Kept as an assertion independent of the regex; the comment now says so. - the EXIT trap ended in a failing test, which under set -e can replace the script's real exit code with that failure. - a provenance LOG LINE read a file through a redirect that set -o pipefail would have turned into a dead worker if the file were absent.

docs(agents): one workspace per agent run — the shared checkout is off-limits
Agents have been working in the operator's checkout and clobbering each other. Nothing in the tree told them not to: worktrees appeared in CLAUDE.md only as §3's gate workarounds, and decisions/README.md described worktree isolation as something agents already do rather than as a rule. New CLAUDE.md §0 states the rule, with the commands and an explicit do-not list for the shared checkout. Placed before §1 so every existing §-reference in the repo keeps its meaning. Measured in the shared checkout on 2026-10-05, each row a distinct failure mode: 107 `checkout: moving` reflog entries; sitting on feat/pm-agent-issue-to-pr, not main; two other runs' untracked trees left in it; local main two commits behind origin/main; 42 registered worktrees of which 31 are on already-merged branches; 9 gate scripts carrying a `.claude/` exclusion because an in-tree worktree made find-based discovery count the same manifest up to 18 times. Corrects a claim carried in earlier briefs: `git worktree remove` is NOT blocked by the agent sandbox. Provoked on a throwaway worktree — rc 0. §3 reframed as the normal path and grown from two breakages to three: spec-immutability's skip is avoidable, not merely tolerated, with the spec repo mounted read-only in the same ENGINE shim plus -e SPEC_REPO=/home-network-k3s. CLAUDE.md is a sensitive path, so this PR needs a non-author review or an administrator /approve-override posted as a PR review. Not posted by me: §1 forbids an agent clearing that on its own PR.

last_activity() is the whole trigger: the PM acts iff the newest thing in a thread was not written by it. It found that newest comment by comparing Gitea's RFC 3339 created_at STRINGS, which is only correct while every offset is identical — true today, silently wrong after a server timezone change, and the failure would be the PM answering its own last comment forever.

feat(vpn-ingress): WireGuard remote access on udp/51820 (hostNetwork, declarative peers)
Lets the operator's Android / Linux / Windows / macOS devices dial in from anywhere and behave like LAN machines: full reach to 192.168.2.0/24 plus internet egress out the house WAN. Opposite direction to platform/vpn-egress, which sends pods OUT through PIA; the two share nothing but the word "VPN". WireGuard because it is the only option with a first-party client on all four named platforms, and because its handshake MAC is keyed with the responder's own public key: an unauthenticated packet gets NO reply, so udp/51820 is indistinguishable from a closed port. That, not "it is encrypted", is what makes an unfiltered WAN port defensible, and why there is no source allowlist. hostNetwork: true is REQUIRED, not convenient. A pod-networked server must SNAT clients to its own pod IP, so every remote client would carry that pod's Cilium identity -- and a pod-sourced request to the shared Gateway VIP returns 403 from Envoy for ALL 16 hostnames (measured 2026-10-04), because Cilium's Gateway preserves the original source identity and enforces the destination's ingress policy. The obvious build would have shipped a healthy-looking tunnel on which every cluster web UI was 403 and *.home.keithjackson.dev did not even resolve. In the host netns traffic is SNATed to the node and arrives as host/remote-node, exactly like a LAN client. It also sidesteps the unsafe ip_forward sysctl, the L2-announcement lease lottery, and double encapsulation (hence MTU 1420). Permitted by restrict-host-namespaces' own carve-out for platform namespaces. The cost is stated in networkpolicy.yaml rather than papered over: no NetworkPolicy constrains a hostNetwork pod. A DaemonSet so the hand-made WAN forward cannot be invalidated by a reschedule; all three nodes answer the same keys, so failover is a one-line router change. Peer PUBLIC keys are plaintext in peers.yaml, which makes "who can get into my house" a reviewable PR diff. The only secret -- the server's private key -- is an out-of-band Secret: an agent must not mint a long-lived private key, and the two halves are joined only at pod start into a tmpfs that dies with the pod. Ships INERT-BUT-HEALTHY with zero peers. THREE off-repo manual steps remain (kernel module, server key, WAN forward) -- runbooks/vpn-remote-access.md. Touches clusters/** , so ci/approval-policy.sh will block pending the operator's /approve-override. Deliberately not posted by me (CLAUDE.md §1).

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(cilium): roll the agents when cilium-config changes (merged config was silently inert)
A merged Cilium config change did nothing, and everything reported success. The Hubble flow exporter (#50, merged 2026-10-04) never took effect: HelmRelease cilium Ready=True, "Helm upgrade succeeded ... cilium.v6" cilium-config hubble-export-file-path: stdout + the allowlist, PRESENT cilium agent pods all three still PRE-MERGE, startTime 2026-10-04T07:11Z exported flow lines 0, 0, 0 Flux every Kustomization Ready=True Cause: the chart's rollOutCiliumPods defaults to false, so Helm rewrites the ConfigMap and leaves the DaemonSet's pod template untouched -- and cilium-agent reads that ConfigMap only at STARTUP. Merged, believed delivered, green everywhere, doing nothing. The same class of failure this repo already guards against elsewhere: a green signal over something that never ran. Confirmed by contrast rather than reasoned: the cgroup fix (#42) DID apply -- both the DaemonSet and the running pod mount /sys/fs/cgroup -- because it changed the POD TEMPLATE, which rolls the DaemonSet on its own. That also explains why the agents are dated 2026-10-04T07:11Z: that was #42's rollout, and nothing has rolled them since. The inertness is specific to ConfigMap-only changes. Set in all three value files to hold the [parity] contract. Cost, and it is the point: every future Cilium config change now rolls the agents instead of waiting for a manual restart. Strictly more honest -- it applies when merged or fails visibly -- but config edits become disruptive by default. maxUnavailable: 1 bounds it to one node at a time. The lease-holding node briefly loses the Gateway, PiHole-DNS and Plex VIPs as it cycles, so merge at a quiet moment. Merging this IS one rollout (the ConfigMap checksum annotation changes the pod template) -- which is what finally activates the Hubble exporter. UNVERIFIED: unreconciled; `filePath: stdout` still unproven and only answerable after the agents restart (check for flow lines immediately); and the rollout's actual impact on LAN DNS is unmeasured.

fix(plex): advertise a resolver-independent plex.direct name again (LAN-wide outage)
I took Plex down for the whole LAN. ADVERTISE_IP was http://plex-vip.${BASE_DOMAIN}:32400 -- a name that exists ONLY in PiHole's split-horizon answers and in no public zone. A Plex client resolves the advertised host ITSELF, with whatever resolver it uses, and on a real LAN that is frequently not PiHole: browsers ship DoH on by default, phones have "private DNS", guest/IoT devices take the router's DNS. Those clients could not resolve the name, the router answered the failed lookup with ITSELF, and they all landed on its web UI -- hence the %D certificate. Measured 2026-10-05: 192.168.2.1:443 -> C=ZZ, O=%D342e7e6b, CN=%D (router, LAN side) 136.51.115.252:443 -> the same %D cert (router, WAN side) pihole-0 AND pihole-1 -> plex -> .20, plex-vip -> .24 (both CORRECT) gateway .20:443 -> CN=*.home.keithjackson.dev, valid http://192.168.2.24:32400/identity -> 200 Plex's published connections: all port 32400, nothing on 443 The DNS was right; the DEPENDENCY on it was the bug. And since nothing Plex advertises listens on 443, the clients had left the Plex path entirely. Fix: <dashed-ip>.<serverhash>.plex.direct, which is RESOLVER-INDEPENDENT -- a public zone returning the private address embedded in the label, so every resolver (PiHole, the router, 1.1.1.1, a DoH browser) answers it with 192.168.2.24. No split-horizon entry, no Cloudflare record and no certificate work needed: the wildcard cert Plex already serves on 32400 covers that name. Re-verified today with full validation (no curl -k): 200, TLS verified. The nicer hostname cannot be made correct for clients that bypass PiHole -- a public record resolves to the WAN address and there is no NAT hairpin, so it is right only for PiHole users and wrong for the rest. There is no configuration of it that is right for both. PiHole's plex-vip answer is KEPT; it is just not what Plex advertises. Cost restated, not buried: the value embeds the VIP and the cert hash as a literal and nothing checks they still agree. Accepted because an unresolvable name is a worse failure -- silent, LAN-wide, and it points users at the router. UNVERIFIED: unreconciled, and the client-side resolver path is INFERRED -- my public-resolver probe was broken (NXDOMAIN even for a name that resolves) so I discarded it. The chain is the only explanation consistent with the measurements, but the NXDOMAIN-hijack step was not observed directly. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

fix(plex): unblock the app tier — drop the Certificate that stalled apps-wave-0, advertise http
I broke the app tier with #48. Two faults, both mine, both measured after merge: 1. KYVERNO BLOCKS cert-manager IN APP NAMESPACES. The temporary private-key Secrets (plex-vip-<random>) were denied by secret-provenance/secrets-must-be-flux-managed, which matches every Secret in a namespace labelled homelab.keithjackson.dev/app-namespace=true and excludes only those labelled secret-managed-by=controller or carrying a Flux label. `plex` HAS that label; `gateway` -- where the working wildcard cert lives -- does NOT. That asymmetry is why the existing Certificate was never affected and mine was, and I did not check it. secretTemplate cannot fix it: those Secrets come from the keymanager controller, not the Certificate template. So no CertificateRequest, Order or Challenge was ever created. 2. FLUX HEALTH-CHECKS THE CERTIFICATE. `optional: true` did its job -- the pod rolled and ran fine without the Secret -- but apps-wave-0 is wait:true, so Flux waits on the Certificate OBJECT: timeout waiting for: [Certificate/plex/plex-vip status: 'InProgress'] apps-wave-0 never went Ready; wave-1/-2 and everything downstream of platform-config sat in DependencyNotReady behind it. I guarded the pod and missed the object. That distinction is the whole bug. Third, independent: the advertised URL was https with no servable certificate -- Plex answers 32400 with its *.plex.direct cert, which cannot cover plex-vip -- the exact failure mode of the outage earlier the same day. So: delete the Certificate (pruning it clears the health gate) and advertise http://plex-vip:32400, which is MEASURED to work today -- PiHole answers the name with the Plex VIP (verified against pihole-0) and Plex serves 32400 there. http is explicitly temporary and only tolerable because remote access does not work yet; the restore condition is written at the call site. DELETED, not merely unregistered: my first attempt kept the file as "tracked but not onboarded" and the gate rejected it -- tls-lifecycle-automated (R-TLS-02) fails any Certificate no Flux path reconciles. Legal for a Deployment, not for a TLS object. The re-enable recipe (Kyverno exemption + a wait:false Kustomization + the https flip, as ONE change) is recorded in catalog/plex.yaml. Kept and verified working from #48: the hostname design, PiHole's split-horizon answer, and the postStart hook -- LanNetworksBandwidth is now set live. Gate: rc 3, all substantive stages pass (first attempt was rc 1 BLOCKED). Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

feat(cilium): export Plex's pre-SNAT client address via Hubble, scoped to tcp/32400
The requirement is log visibility only -- which address connected to Plex.
Plex's own log cannot show it. Every LoadBalancer Service here is
externalTrafficPolicy: Cluster, so the node holding the VIP's L2 lease SNATs
the client before forwarding to the backend pod. Measured: Plex had logged
3,214 requests from 10.0.1.x (lease holder k3s-prod-3's own address, Cilium
identity 1 = reserved:host) and ZERO from any 192.168.x address, ever. No
X-Forwarded-For either -- it serves raw tcp/32400, not HTTP via the Gateway.
Nothing on the router does this; there is no hairpin NAT. It is Cilium.
The address is not lost, only unrecorded. Cilium observes the flow at ingress,
BEFORE its own translation, so Hubble already has it:
192.168.2.133 -> 10.0.0.135 real LAN client -> the Plex pod
10.0.1.78 -> 10.0.0.135 same traffic post-SNAT, what Plex sees
What was missing is RETENTION: 4095/4095 flows at ~303/s is about thirteen
seconds of history, metrics disabled, no exporter configured.
So enable the static exporter, port-scoped, to the agent's stdout -- Alloy
already tails every pod into Loki, so this needs no new mount, no rotation
handling and no Alloy change.
{namespace="kube-system", app="cilium"} |= "32400"
Scoped BY PORT, not namespace, on evidence: --to-namespace plex returned only
the post-SNAT flows; the record carrying the real client address did not match
it. A namespace filter would drop exactly what this exists to capture.
Rejected, with reasons: eTP:Local is incompatible with cilium 1.20's L2
announcer per upstream docs for this version ("may cause service IPs to be
announced on nodes without pods causing traffic drops") -- and the VIP is on
prod-3 while the pod is on prod-1, so it would black-hole 32400 immediately;
making it safe costs Plex its ability to reschedule. DSR: routing-mode is
vxlan, not native/geneve, and DSR returns bypass the ingress node, breaking
the router's stateful NAT on the remote path.
Also corrects the repo's own record: 2026-10-03 says the SNAT lands in
192.168.0.0/16 (the node's LAN address). It is 10.0.1.x, the cilium_host
inside the pod CIDR -- which is why LanNetworksBandwidth can never separate
local from remote while eTP is Cluster.
UNVERIFIED and stated in the handoff: nothing is reconciled; `filePath: stdout`
is taken from a verbatim upstream sentence but not confirmed against 1.20.1
source (a wrong notation is a silent no-op, with the file+Alloy fallback
documented); the port FlowFilter has no upstream example; and this change
ROLLS CILIUM -- prod-3 announces the Gateway, PiHole DNS and Plex VIPs, so a
lease move during the rollout could briefly interrupt LAN DNS.

fix(obs): open 44180 to ns monitoring so the forward-auth gate sidecars are actually scrapable
platform/oauth2-proxy/podmonitor.yaml landed 2026-10-02 and discovered six targets that have never once scraped. Measured on prod 2026-10-04: all six read health=down with lastError "context deadline exceeded" and lastScrapeDuration exactly 10.0s — the configured scrapeTimeout, i.e. packets DROPPED rather than refused. Cause: every app namespace ships a default-deny NetworkPolicy with policyTypes: [Ingress, Egress] and NO ingress key at all (deny-all-ingress), and the only ingress allowance is <app>-allow-gateway-ingress: fromEntities: [ingress] -> 4180. Prometheus matched no clause. Verified identical in all six of jackett, radarr, sonarr, qbittorrent, pihole, crafty; zero namespaces had any -allow-monitoring-scrape object. render.py already had the right idiom — r_monitoring_ingress_policy — but it returned None unless the service declared observability.metricsEndpoint, and NO ServiceDefinition in this catalog declares one. It was wired in at the call site and had never emitted a single object on any branch: correct, and entirely latent. It now also fires for the forward-auth gate sidecar's own metrics port, keyed on _needs_oauth2_sidecar — deliberately the same condition the scrape keys on, since podmonitor.yaml selects pods purely by the auth-mode label, so a target exists iff the sidecar exists. Keying on observability.metrics instead would let metrics: false produce a discovered-but-blocked target: the same "two halves authored apart" failure this function exists to prevent. Rendered here rather than in platform/oauth2-proxy because that tier would have to name app namespaces created by the sibling apps-wave-0/1 tiers — it would apply on a running cluster and fail on a cold bootstrap. podmonitor.yaml's header records that objection; rendering per-app dissolves it. Five CNPs result, one per forward-auth app, each opening only 44180 to only ns monitoring. apps/ re-rendered with the invocation it was generated by (--no-image-automation, verified byte-identical beforehand); --emit-waves deliberately not run, so no wave kustomization moved. Three L1 goldens are regenerated with it (+63 lines, -0): a renderer change that adds an object necessarily drifts the goldens that pin the renderer's output. The first gate run caught container-workload-render and egress-class-render as FAIL with exactly this CNP as the drift. default-deny-baseline-render's golden regenerated byte-identical, which is the evidence that the regen is faithful and not a rubber stamp. That puts conformance/** in the diff, which is a sensitive path: this PR needs a non-author approving review. The local gate cannot see that — offline it reports approval-policy green (N/A). Local toolbox gate: rc 3 UNDETERMINED, not 0. Every stage that ran is green and l1 went FAIL -> pass with the goldens; the only not-run stage is gitea-settings (no GITEA_SETTINGS_TOKEN). L2/L3 conformance is UNVERIFIED for all 8 touched requirements. Not verified: that the scrape now succeeds. Nothing is applied until Flux reconciles main.

feat(plex): one advertised hostname for local+remote, its own LE cert, and a LAN definition
Two symptoms after the publishing fix landed:
1. LAN clients were reported as Remote. Measured root cause:
LanNetworksBandwidth was ABSENT, so Plex had no notion of a local
network and classified everything WAN -- 468 requests logged
"Allowed Network (WAN)", ZERO "(LAN)", including Seerr from inside the
cluster. allowedNetworks only waives AUTH; it does not make a client
local. Two settings, and only one has an env hook.
2. The advertised URL hard-coded both the VIP and the server's cert hash
into a cluster-var -- two values nothing kept in sync.
Operator design: ONE hostname, plex-vip.${BASE_DOMAIN}, split-horizon --
PiHole answers it with ${PLEX_L4_VIP} on the LAN, Cloudflare answers it
publicly with the WAN address NATed to the same VIP.
- catalog/plex.yaml: ADVERTISE_IP -> https://plex-vip.${BASE_DOMAIN}:32400,
plus a level-triggered postStart hook (pihole/qbittorrent idiom) that
re-asserts LanNetworksBandwidth and the three customCertificate* prefs
every start, converting PEM -> PKCS#12 so cert renewals need no extra part.
- apps/wave-0/plex-cert.yaml: cert-manager Certificate for exactly that
name from letsencrypt-prod, so the advertised https URL is servable.
- schema 1.11.0: `optional` on secretKeyRef/configMapKeyRef. Load-bearing --
the cert is issued INTO the plex namespace, which the rendered plex.yaml
itself creates, so it lands in the same reconcile; hard refs would have
held Plex in CreateContainerConfigError and, since apps-wave-0 is
wait:true, stalled the whole app tier on a slow DNS01 challenge.
- catalog/pihole.yaml: the plex-vip split-horizon answer. Required --
measured, the name resolved to the Gateway VIP where nothing listens
on 32400 (http=000).
- PLEX_ADVERTISE_URL deleted; the hostname removes the cert-hash fragility.
Corrects my own earlier claim that a SAN match is REQUIRED: it is not
(httpsRequired=0, secureConnections defaults to Preferred, so clients can
fall back to cleartext). A matching cert keeps the remote leg ENCRYPTED.
Hence: obtain a real cert for the advertised name rather than pick the name
to suit Plex's built-in one.
UNVERIFIED, and stated plainly in the handoff: nothing here has run. Cert
issuance for this name is inferred from the wildcard's success, and whether
Plex accepts an OpenSSL-3 PKCS#12 bundle is untested -- the largest risk.
Touches clusters/** -> sensitive paths -> needs a non-author approval or the
operator's /approve-override; deliberately not self-posted (CLAUDE.md 1).

fix(plex): advertise the plex.direct name, not the bare VIP (server vanished from the plex.tv account)
customConnections held two hand-typed URLs and neither could ever complete, so Plex had nothing publishable and the server disappeared from the account: - https://192.168.2.24:32400 -- the server's cert is *.130072f20c334d6c8f63d0dfef87309b.plex.direct with NO IP SAN, so bare-IP https fails TLS for every client. Measured: a continuous storm of "CERT: incomplete TLS handshake ... certificate unknown" from real LAN clients arriving through the plex-l4-tcp VIP. - https://plex.home.keithjackson.dev:32400 -- nothing listens; the Gateway serves that host on 443 (measured http=000 against 192.168.2.20:32400). With no completable connection plex.tv published nothing ("Mapped - Not Published"), Plex fell back to Relay, and clients reported "not authorized". Fix: advertise <dashed-ip>.<serverhash>.plex.direct -- public DNS that resolves to the embedded address, so it points at the LAN VIP and matches the wildcard cert. Verified with full TLS validation (no curl -k): 200 + verify OK, where the bare-IP form fails to connect. Declared as ADVERTISE_IP so git owns the value instead of a web form: the image's 40-plex-first-run writes it into customConnections on every pod start, outside the claim guard. Does NOT fix off-LAN access -- the advertised address is RFC1918 and the WAN tcp/32400 forward remains unverified. ManualPortMappingMode=1 with an absent port is left as-is (no GitOps path exists for it). Touches clusters/** -> sensitive paths -> needs the operator's /approve-override, deliberately not self-posted (CLAUDE.md 1). Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

feat(pihole): two replicas on different nodes, and fix a PVC mounted where pihole never writes
Phase 2 of making LAN DNS survive a node failure. Pihole was one pod on one node; measured 2026-10-04, losing that node meant roughly 6-10 minutes with no LAN resolution (tolerationSeconds 300 + NotReady detection + a Longhorn RWO force-detach), while losing the node holding the pihole-dns L2 lease -- a DIFFERENT node -- meant tens of seconds. Two of three nodes were single points of failure with wildly different blast radii. Adds `availability.replicas` to the ServiceDefinition schema (1.10.0). Intent only; the mechanism is render.py's, documented in the renderer contract. 1 or absent renders a Deployment exactly as before -- verified byte-identical across the whole apps/ tree. >1 renders a StatefulSet (a longhorn PVC is RWO, so a multi-replica Deployment never schedules the second pod), per-replica volumeClaimTemplates, REQUIRED hostname anti-affinity, podManagementPolicy Parallel, a minAvailable:1 PodDisruptionBudget, and an SLI that follows the rendered kind (a Deployment-shaped rule against a StatefulSet absent()s forever). Pinned by ~20 new --selftest assertions rather than a conformance change. ALSO FIXES A LIVE BUG. Pihole's config PVC was mounted at the renderer default /data/config, but pihole writes to /etc/pihole. Measured: /etc/pihole (7.1M -- gravity.db, pihole.toml, query DB) was on the OVERLAY, while the 2Gi Longhorn volume held lost+found and 24K of nothing. So every restart discarded all state and re-downloaded 72k gravity domains, and backup.policy has been backing up an empty volume while reporting success. Fixed here because otherwise the new per-replica volumes would hold nothing while state stayed ephemeral -- and because persisting gravity.db is what makes a restart cheap. The /etc/pihole mount is safe on the image's own evidence: start.sh is PID 1 as uid 0 and chowns the directory recursively (no fsGroup needed), and it calls migrate_gravity which creates the database when absent. The gate caught a real regression on the first run: the wave-0 alert unit test fed pihole a Deployment-shaped series. Updated; promtool SUCCESS. Touches no sensitive paths, so this one needs no override. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

feat(pihole): declare the admin password and adlists in git
Prerequisite for running more than one PiHole replica. A second replica with a fresh PVC would have come up serving DNS and blocking nothing, with a different admin password -- answers varying by which pod replied. pihole.toml's own ### CHANGED markers gave the exact inventory: four settings already came from env (declared), one came from the image, and exactly ONE operator-set value lived only on the PVC -- webserver.api.pwhash, a one-way hash nobody could recover. Separately the adlists were undeclared: one list and 72,234 gravity domains that nothing in this repo named. Declares both: - A SOPS secret feeding FTLCONF_webserver_api_password. webserver.api.password takes cleartext and FTL hashes it itself (verified: pihole setpassword IS setFTLConfigValue on that key), so the PVC's pwhash becomes derived state. - A level-triggered postStart hook that reconciles the declared adlist set into gravity.db -- adds, re-enables, and disables (never deletes) undeclared lists, running pihole -g only when something moved. A file would not work: v6's adlists.list import is migration-only, guarded on the DB not existing. The rendered hook was run in the live pod against throwaway copies of gravity.db, exercising all four paths. A fresh DB built from the image's own schema template has ZERO adlists, confirming this is load-bearing rather than cosmetic. Password kept rather than set empty: the pihole Service still publishes port 80 past the oauth2-proxy, closed only by policy, and default-deny has drifted here before. Multi-replica is phase 2 and deliberately not in this branch -- it needs a schema field, a StatefulSet (the config PVC is RWO), anti-affinity and a PDB. Adds a *.sops.yaml -- a sensitive path -- so approval-policy will block pending an operator /approve-override. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

feat(plex): expose tcp/32400 for remote access via a pinned LoadBalancer VIP
Remote Plex clients had no path in, for two measured reasons: Plex advertised no remote connection at all (customConnections and ManualPortMappingMode both ABSENT while PublishServerOnPlexOnlineKey=1), and its Service was ClusterIP, so 32400 had no off-cluster path. The L7 Gateway was NOT the problem -- it serves Plex correctly (200, claimed=1, 401 on protected endpoints) -- but Plex clients discover servers through plex.tv, not DNS, so an HTTPRoute cannot put this server on a client's connection list. Operator chose the native path over ADVERTISE_IP: Plex terminates its own TLS with *.plex.direct and streams bypass the Envoy L7 hop. Adds a hand-written non-catalog unit (the SD schema cannot express a LoadBalancer Service or a pinned lbipam VIP), registered in render.py's EXTRA_UNITS so --emit-waves places it in plex's own wave. externalTrafficPolicy: Cluster, inheriting crafty's 8-day-outage lesson rather than re-deriving it. Known consequence, documented: SNAT puts remote clients inside ALLOWED_NETWORKS, so Plex meters them as LAN. Not an auth change. Remote access does NOT work until the operator does two manual steps that cannot live in this repo -- the WAN tcp/32400 forward and Plex's "manually specify public port" toggle (no env var exists for it; verified NONE in the image's init surface). runbooks/plex-remote-access.md is the procedure. Touches clusters/** -- a sensitive path -- so the approval-policy stage will block pending an operator /approve-override. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |
