feat(dns): publish public names as proxied CNAMEs to the Cloudflare Tunnel
Gateway target -> fc81938b-...cfargotunnel.com, --cloudflare-proxied globally, L4 service publishers (unifi, crafty-mc) pinned DNS-only, Plex web UI and Headlamp disowned (LAN/VPN-only). L0 internal-services-publish-no-public-dns gains assertion (9) tying the Gateway target to the tunnel UUID, requiring cloudflare-proxied=false on every service-source publisher, and keeping the tunnel's 404 list and the unpublished set consistent. L2 dns-exposure fixture opts out of proxying. Co-Authored-By: Claude Opus 5.5 <[email protected]> |

feat(images): pin pihole, jackett and plex to the digests already running; Renovate follows them
pihole/pihole (no tag) -> 2026.10.0 sha256:d3413471... lscr.io/linuxserver/jackett:latest -> v0.24.2865-ls7 sha256:4fcf3cc2... plexinc/pms-docker:latest -> 1.43.4.10903-e5521bd8c sha256:e0ab2739... Each tag was resolved against its registry and matched the pods' imageID, so the image is unchanged (the pod template string does change, so Flux rolls the three workloads). renovate.json5: regex versioning for jackett (-lsN) and plex (build-hex); jackett is looked up on ghcr.io via overridePackageName, because lscr.io is capped at dockerMaxPages=20 pages and jackett's 32k tags put the running one at #31,980 (dry run proposed nothing without it); jackett weekly (13 builds in 12 days); pihole deliberately unheld, year rollover = major. Stale "publishes only latest" prose fixed in renovate.json5 and three runbooks. Co-Authored-By: Claude Opus 5.5 <[email protected]> |

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(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(gpu): satisfy hardware.gpu: intel-quicksync with gpu.intel.com/i915, not a /dev/dri hostPath
The hostPath mechanism was MEASURED NOT TO WORK. In the live Plex pod on
k3s-prod-2, 2026-10-01: the device node was VISIBLE in the container
(`crw-rw---- root video2 226,128 renderD128`) and could not be opened --
`uid 0 O_RDWR -> EPERM` and `uid 1000 O_RDWR -> EPERM`. EPERM from the DEVICE
CGROUP, not EACCES from file permissions, proven three ways: root on the HOST
opens the same device rc=0; the node is unified cgroup2fs; and the container's
runc config.json read `linux.resources.devices: [{allow: False, access: 'rwm'}]`
with `linux.devices: None` -- one deny-all rule, no allow entry for major 226.
A hostPath is a filesystem operation: it binds the device node in but adds no
cgroup allow rule, because Kubernetes cannot infer one from a volume.
The Intel GPU device plugin produces that allow rule
(`createDeviceSpecsFromDrmFiles` emits `DeviceSpec{..., Permissions: "rw"}`).
It shipped as #36 and is live: all three prod nodes advertise
`gpu.intel.com/i915: 1`, DaemonSet 3/3/3 (measured 2026-10-01).
ZERO ServiceDefinition field changes, which was the entire point of making the
field an enum of capability classes rather than a device path. `catalog/plex.yaml`'s
`hardware:` block comes through byte-identical; only its comment changes, because
it restated the old mechanism. Contract invariant 8 holds, now demonstrated rather
than claimed.
- catalog/render.py: `DRI_VOLUME_NAME`/`DRI_DEVICE_DIR` retired for
`QUICKSYNC_RESOURCE`; the hardware branch now sets
`resources.limits["gpu.intel.com/i915"] = 1` on the APP container only (never a
sidecar) and emits no volume, no mount, no securityContext, no nodeSelector.
`limits` not `requests` is mandatory: Kubernetes mirrors requests from limits,
and a requests-only extended resource is invalid. This is the only app-container
`resources` render path and is deliberately narrow -- no general CPU/memory
feature was invented.
- selftests: resources dict asserted EXACTLY; hostPath/mount asserted ABSENT; the
no-`hardware` negative extended to `resources`; the podSecurityContext
pass-through and the no-synthesised-securityContext assertions kept; one new
assertion that the limit never reaches the oauth2-proxy sidecar. Mutation-tested:
8/8 mutants caught (requests-instead-of-limits, emission dropped, hostPath
re-added, emitted unconditionally, supplementalGroups synthesised, wrong resource
name, quantity as a string, limit leaked onto the sidecar).
- apps/wave-0/plex.yaml: six hostPath lines removed, a three-line resources block
added. Only golden touched; keycloak/vm-demo unchanged.
THE REGRESSION, STATED RATHER THAN SOLD. Before: device missing ->
`DirectoryOrCreate` mounted an empty dir -> Plex ran and SILENTLY
software-transcoded (invisible, harmless to everything else). After: resource
unavailable (plugin broken, removed, or not yet reconciled) -> Plex is
UNSCHEDULABLE, and `apps-wave-0` is `wait: true` with `apps-wave-1` dependsOn it,
so that STALLS THE APP TIER. Unavoidable: an extended resource is a hard
scheduling constraint, and it is also the only thing that produces the cgroup
allow rule. There is no graceful-degradation variant. Plex's schedulability is now
coupled to the intel-gpu-plugin DaemonSet. Escape hatch, one field and no code
change: delete the `hardware:` block from catalog/plex.yaml and re-render.
Documented in the contract, the runbook (its own top-of-page section and a
"Plex will not schedule" procedure) and the handoff.
HARDWARE TRANSCODING IS STILL NOT OBSERVED WORKING. The decisive open() test
cannot be re-run until this merges and Flux reconciles, and the Plex-side
`HardwareAcceleratedCodecs` toggle is still unset. A green gate proves the
manifest renders.

feat(plex): opt into hardware.gpu: intel-quicksync, and write the runbook for the step GitOps cannot reach
Plex has been transcoding in software on hardware that can do it in the iGPU. This opts its ServiceDefinition into the `hardware` capability from #27 and re-renders. catalog/plex.yaml gains four lines of YAML and the comment that explains them: hardware: gpu: intel-quicksync which renders exactly two things into apps/wave-0/plex.yaml and nothing else — a `dri` hostPath volume (/dev/dri, type: DirectoryOrCreate) and a read-write /dev/dri volumeMount on the app container. Whole-tree render diff: 6 added lines, one file. The comment records what is not obvious from the four lines: the device exists on ALL THREE prod nodes with i915 bound (so no nodeSelector is rendered and none is wanted); why `supplementalGroups` would be INERT rather than a hardening (the image's cont-init hook adds the plex user to the device's group inside the container, and s6-setuidgid then REPLACES the process group list from /etc/group, discarding anything Kubernetes supplied); and why `DirectoryOrCreate` is load-bearing (apps-wave-0 is wait:true with apps-wave-1 depending on it, so a failed mount would stall the whole app tier for a feature that is not). THE FEATURE IS INERT UNTIL A HUMAN CLICKS A BOX, and that is the part this commit is really about. Mounting the device does not enable hardware transcoding; Plex's `HardwareAcceleratedCodecs` preference does, and it is ABSENT from Preferences.xml — the toggle has never been on. It cannot be automated: a bounded grep across the running image's entire init surface (/etc/cont-init.d, /etc/services.d, /etc/fix-attrs.d, /plex-common.sh, /usr/local/bin) found ZERO PLEX_PREFERENCE* support, and the six setPref keys the image does write are all unrelated. So runbooks/plex-quicksync.md is the procedure, registered in the configMapGenerator (a runbook in git with no generator entry is reviewed, merged, and still a 404) and indexed in runbooks/README.md. It covers the GitOps/manual boundary, the toggle and the real preference keys (including the widely-cited one that does not exist and the upstream misspelling nobody should "fix"), verification via `Transcode (hw)` on the Plex dashboard — stated plainly as the ONLY proof, because Plex renders no ServiceMonitor and an alert could never fire — the device-cgroup failure to expect first with its Intel-device-plugin fallback, and the floating-`:latest` caveat. Stacked on #27 (feat/sd-hardware-capability), which is open and unmerged; that branch's commit is in this range by design and this must merge after it. NOT VERIFIED, and the handoff says so at length: hardware transcoding has not been observed working. Whether containerd's device cgroup lets a non-privileged pod open() a bind-mounted char device is an open question that only deploying settles, and the Plex-side toggle was still unset at the time of writing. A green gate proves the manifest renders; it proves nothing about transcoding. Gate (pinned toolbox, worktree): rc 3 — UNDETERMINED, not green. Passed: decisions-log, lint, l0, render-golden, l1, approval-policy. Skipped (the known local ceiling): spec-immutability (no sibling spec repo), gitea-settings (no SETTINGS_API_TOKEN), conformance (CLUSTER_AVAILABLE unset, so L2/L3 did not run). No fourth skip, nothing failed. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

feat(plex): wire PLEX_CLAIM from a SOPS Secret so the server can be claimed
Plex cannot create libraries over the already-mounted 8.33T NFS bulk share while the server is UNCLAIMED. catalog/plex.yaml carried a long argument for leaving PLEX_CLAIM unwired; the operator has decided to override it. This implements the wiring in the way that respects the half of that argument which is still true. WHAT WAS TRUE AND STILL IS: a https://plex.tv/claim token has a ~4-minute TTL, far shorter than commit -> push -> Flux reconcile -> pod-roll on its own timers. So the committed value is a documented PLACEHOLDER and the live token is injected by the operator inside that window, with the reconcile FORCED rather than waited for. runbooks/plex-claim.md is that timed procedure. WHAT WAS NOT TRUE: the old comment claimed "a placeholder/absent claim Secret would crashloop the pod". Half of that is wrong, and the difference is the whole design. Established from plexinc/pms-docker's own first-run script (branch `master`, root/etc/cont-init.d/40-plex-first-run, s6-overlay v2), cross-checked byte-identical against the same file inside the running :latest image: * the claim exchange (line 106) is gated on PLEX_CLAIM being non-empty AND the PlexOnlineToken pref in /config being empty. Once the server is claimed the block is skipped entirely, so the env is a NO-OP on every later start whatever it holds ("If server is already logged in, this parameter is ignored" -- upstream README). * with an invalid/expired token on a still-unclaimed /config, plex.tv answers 403 with an empty body; curl's status is never checked, the token sed yields empty, the success branch at line 120 does not fire, there is no else branch and no non-zero exit, and the script (no `set -e`) exits 0. The pod comes up UNCLAIMED AND SERVING. It does not crashloop. * the image never sets S6_BEHAVIOUR_IF_STAGE2_FAILS (default 0 = continue even if a cont-init script failed), so even a non-zero exit would not halt startup. An ABSENT Secret is the real hard failure (secretKeyRef has no `optional`, so it is CreateContainerConfigError), which is why the Secret is committed, encrypted and listed in the wave kustomization rather than hand-created at claim time. NO SCHEMA CHANGE. `optional` on secretKeyRef would only be needed if the pod had to tolerate a missing Secret or could not start without a VALID token. Neither holds: the Secret always exists in the Flux graph, and an invalid token is non-fatal. schemas/servicedefinition.schema.json is untouched, and so are catalog/render.py's env emission and the renderer contract. Changes: * apps/wave-0/plex-claim-secret.sops.yaml -- new Opaque Secret plex-claim/plex, key PLEX_CLAIM, SOPS-encrypted to the committed age recipient. Its header carries NO dollar-brace expressions on purpose: kustomize preserves body comments into the stream envsubst reads (per conformance/tests/l0-static/flux-postbuild-substitution), so quoting the upstream shell conditions verbatim would have been a live substitution hazard on apps-wave-0, not prose. * catalog/plex.yaml -- the PLEX_CLAIM env via valueFrom.secretKeyRef, the "deliberately NOT set" block rewritten around the TTL + one-shot design, and the stale crashloop claim in the /config storage comment corrected. * apps/wave-0/plex.yaml -- re-rendered with the canonical command (`--all catalog -o apps --wave-layout --no-image-automation`). No L1 golden under conformance/tests/l1-rendering covers plex, so this is the only rendered surface that moves. * catalog/render.py -- plan_apps_waves places `<svc>-claim-secret.sops.yaml` in the app's OWN wave, like the bootstrap secret, plus a selftest assertion. Without this, the next `--emit-waves` would have silently dropped the Secret from apps/wave-0/kustomization.yaml and put the pod into CreateContainerConfigError. apps/wave-0/kustomization.yaml is the hand-pruned subset (vm-demo/keycloak are rendered but deliberately unlisted), so its one new line was applied without re-emitting the rest. * runbooks/plex-claim.md + its kustomization.yaml generator entry + README index -- the operator procedure that fits in 4 minutes, including the single forced-reconcile command and the mandatory pod roll (a changed Secret does NOT restart anything: PLEX_CLAIM is read only at container start and the pod template is byte-identical across this change). Touched requirements: R-SEC-01 (secrets encrypted at rest), R-GITOPS-02 (ServiceDefinition onboarding contract). Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> |

fix(obs): twelve app SLI rules read a signal that exists; kill the dead ServiceMonitors
Twelve `<app>-down` SLI rules were STRUCTURALLY INERT. Each read `up{job="<app>"} == 0`,
and the ServiceMonitor rendered beside it named `endpoints[].port: metrics` — a port NO
rendered app Service defined. Every monitor discovered ZERO targets, so no `up{job="<app>"}`
series existed and the rule could not fire. Verified on prod before this change:
`count by (job) (up)` listed 24 jobs and not one of the twelve appeared; `up{job="plex"}`
and `up{job="gitea"}` both returned nothing. `PrometheusTargetsMissing` could not see it
either — a target that was never discovered has no `up` series to be 0.
THE PORT NAME WAS NEVER THE MISSING PIECE. Ground truth per app: Plex, Pi-hole, Jackett,
qBittorrent, Sonarr, Radarr, Seerr, Semaphore and Nextcloud export NO Prometheus metrics
without a separate exporter sidecar; Gitea can but only with app.ini metrics enabled;
Keycloak does, on the operator's management port, already scraped by
platform/keycloak/servicemonitor.yaml; vm-demo is a KubeVirt VM with no Service at all, so
its monitor selected nothing whatsoever. `metrics: true` was asserting a fact none of them
had. There was also a THIRD layer of inertness nobody had hit yet: every app namespace ships
default-deny with `ingress: []` and the renderer emitted no monitoring allow, so even a
correct port would have been dropped by policy — while renderer-contract.md claimed the
baseline carried such an allow.
FIXED IN THE GENERATOR, not in twelve rendered files:
* `slis: [up]` now renders a `<app>-down` alert against kube-state-metrics readiness of the
service's own workload object —
`kube_deployment_status_replicas_available{namespace,deployment} == 0 or absent(...)`,
`kube_statefulset_status_replicas_ready` for a StatefulSet, and
`absent(kubevirt_vmi_info{namespace,name,phase="running"})` for a VM. The same idiom
KeycloakDown has used since it was fixed. kube-state-metrics IS scraped, so this needs no
exporter and no new target. The `or absent(...)` half is load-bearing: the signal
DISAPPEARING now fires the alert instead of silencing it.
* schema 1.6.0 adds `observability.metricsEndpoint` — WHERE metrics are served. A
ServiceMonitor is rendered ONLY from it, and it renders all three halves of a working
scrape together: the named Service port, the monitor endpoint, and the
monitoring-namespace CiliumNetworkPolicy allow. No catalog entry declares one, so twelve
dead ServiceMonitors are gone. `metrics: true` keeps meaning logs-to-Loki plus
kube-state-metrics liveness.
* schema 1.6.0 also adds `observability.livenessWorkload`, and catalog/keycloak.yaml uses
it. Keycloak's server is a StatefulSet run by the operator; the default Deployment shape
would have made its `absent()` half fire FOREVER — the other failure mode this repo has
shipped.
* renderer selftest gains cases 9/9a/9b/9c: no metricsEndpoint => no monitor; the up SLI
must not read `up{job=...}`; endpoint port must exist on the Service; the metrics port
must NOT reach the Gateway allow; an unknown livenessWorkload.kind is REFUSED.
PROOF, both directions, for all twelve (apps/wave-{0,1,2}/tests/app-slis.test.yaml, run by
platform/monitoring/tests/run.sh over the RENDERED manifests):
* quiet on the healthy state; firing on no-ready-replica; firing when the series is ABSENT;
the VM asserted both gone and in a non-running phase; per-app isolation asserted, and
keycloak asserted un-maskable by its neighbours (keycloak-operator Deployment,
keycloak-db StatefulSet ready in the same namespace).
* mutation-checked: six mutations, each turning its suite red — reverting plex to
`up{job=...} == 0`; dropping seerr's `absent()` half; pointing keycloak at a Deployment;
capitalising the VMI phase to `Running`; widening keycloak's matcher to the namespace;
inverting plex's `== 0` to `!= 0`. Control run green.
* live on prod with `promtool query instant`: all ten deployed app Deployments export
`kube_deployment_status_replicas_available`,
`kube_statefulset_status_replicas_ready{namespace="keycloak",statefulset="keycloak"}` = 2,
`kubevirt_vmi_info` present with a lowercase `phase="running"`; and evaluating the twelve
SHIPPED expressions returns no series for eleven (quiet, not permanently firing). The
twelfth is vm-demo, which is not in apps/wave-0/kustomization.yaml and so is not deployed
— its rule is not applied either.
DELETION WAS NOT THE ANSWER, and the evidence is recorded rather than assumed:
kube-prometheus-stack's `kubernetes-apps` group IS live on prod (17 rules, KubePodNotReady /
KubeDeploymentReplicasMismatch among them), so app pods are not unmonitored — but that is a
generic warning keyed to a namespace, not the per-service CRITICAL SLI R-OBS-01 declares.
platform/monitoring/alerts.yaml carries no generic app-readiness rule at all.
GUARD SO IT CANNOT RECUR SILENTLY: new whole-repo L0 invariant
conformance/tests/l0-static/servicemonitor-ports-resolve. It walks the MONITORS, not the
alerts, so it needs no `up{job=...}` rule to reach one, and resolves each endpoint by SELECTOR
across the whole tree rather than by same-file adjacency. Fixing the alerts DELETED the only
thing that made the broken monitors visible to the sibling check, which is exactly why this
axis needed its own home. It declares `conformance.home.k3s/scope: whole-repo` and adds no
ci/l0.sh stage. Proven to FAIL on the pre-fix tree: 15 failures — eleven port disagreements,
vm-demo's monitor matching no Service at all, and the three generator/contract assertions —
and to pass after. Its resolver is additionally proven on in-check fixtures (agreeing pair
accepted, disagreeing pair rejected, target-less endpoint rejected), because after the fix
there are zero in-repo monitors left for it to judge and a guard whose only evidence is
"nothing failed" cannot be told apart from one that stopped working. It also asserts
r_servicemonitor does not HARDCODE a port name — the mechanism by which one edit gave twelve
services the same wrong one.
Also fixed, found on the way:
* platform/monitoring/tests/run.sh discovered the SUITE convention only inside
platform/monitoring/tests/ while documenting it as general — a suite added anywhere else
was never run and still looked like coverage. Now discovered tree-wide; a misplaced
*.test.yaml fails loudly instead of vanishing.
* KNOWN_UNWIRED_JOBS in alert-metrics-have-scrape-targets is now EMPTY, and the twelve
apps/* entries in alert-rules-unit-tested's UNTESTED_FILES are gone — both because the
gaps were CLOSED, not waived. Both registers are shrink-only and a stale entry fails.
* renderer-contract.md claimed the default-deny baseline carried a standing monitoring
scrape allow. It never did; the claim is corrected and the allow is now real, per declared
metrics endpoint and scoped to that one port.

feat(apps): attach the media library and the legacy Nextcloud dataset over NFS
plex, sonarr, radarr and nextcloud each gain one bulk volume. Authored in the catalog and re-rendered, never hand-edited into apps/ (render-golden: 10/10). Layout, the export change the operator must apply, the uid analysis and the validation probes are in docs/BULK-NFS-STORAGE.md; everything there was measured on the host over read-only SSH, not assumed. WHAT THE LAYOUT TURNED OUT TO BE, AND WHY IT DECIDED THE DESIGN /mnt/Storage/plex holds movies/ tv/ photos/ AND downloads/ as SIBLINGS in one dataset — so the arrs' import source and their libraries are one filesystem on the server, and the download client's completed folders are already named radarr/ and tv-sonarr/. The k3s arrs are joining a tree an arr stack has been driving for a long time. That sibling fact is the whole argument for the arrs mounting the export ROOT rather than a subPath per directory. Sonarr and Radarr import by hardlinking or atomically renaming, both same-filesystem operations, and to the kernel "same filesystem" means SAME MOUNT. Two subPath mounts of one export are two mounts: link() across them returns EXDEV regardless of what the server knows, and the arrs do not fail loudly — they degrade to copy-then-delete, rewriting every file over NFS and destroying the seeding copy. The smallest subtree containing both tv/ and downloads/ IS the export root, so the root mount is the MINIMAL mount that preserves hardlinks. Least privilege bounded below by a hard requirement. The cost is stated, not hidden: sonarr can also write /media/movies. plex /mnt/Storage/plex -> /media ro ReadOnlyMany sonarr /mnt/Storage/plex -> /media rw ReadWriteMany radarr /mnt/Storage/plex -> /media rw ReadWriteMany nextcloud /mnt/Storage/nextcloud -> /mnt/legacy-nextcloud ro ReadOnlyMany (subPath: nextcloud) Plex is read-only because it indexes and streams; every write on that tree belongs to the arrs, and saying so removes Plex from the set of things that can damage 8.33 T. All three media consumers use the SAME mountPath deliberately: when qbittorrent is eventually given this export, the arrs and the download client will already agree on absolute paths, which is the other precondition for hardlinked imports. *** /media AND NOT /data — A COLLISION CAUGHT WHILE RENDERING. *** The arrs' Longhorn config PVC renders at the renderer default /data/config. A media mount at /data is mounted OVER it and MASKS the config volume: the pod comes up with its app database shadowed by an 8 T media tree. That discovery also exposed a SEPARATE PRE-EXISTING BUG, reported and deliberately NOT fixed here: LinuxServer arr images run with -data=/config, so /data/config is very likely the wrong home for that PVC and the app has been writing its EPHEMERAL layer — the exact failure catalog/plex.yaml's mountPath comment records already having been bitten by. Plex was fixed; sonarr, radarr, qbittorrent and jackett were not. Fixing it starts those apps from an empty config volume, so it needs its own change with the operator present. This change does not make it worse. UID/GID — THE FAILURE THIS TIER ALWAYS HAS The export is sec=sys + no_root_squash, so the client's numeric uid passes through verbatim and the server's ownership is the entire access story. The tree is 0755 owned 1000:3000, so ONLY uid 1000 can write it. LinuxServer images default to 911. Without intervention sonarr and radarr would have mounted cleanly, gone Ready, and failed EVERY import with EACCES. And fsGroup cannot fix that — the in-tree NFS plugin does NO ownership management, so podSecurityContext.fsGroup is a no-op on an NFS volume. Reaching for it is how this gets misdiagnosed. So PUID=1000/PGID=3000 are added to both arrs (PGID 3000 keeps what they write group-readable to the live non-k3s consumers of the same export), and fsGroup: 3000 is added for the LONGHORN config PVC only, so changing PUID does not depend on the image re-chowning /config. plex already runs as 1000 and reads a 0755 tree; nextcloud reads as www-data. Neither needs work. NEXTCLOUD IS MOUNTED READ-ONLY, WHICH IS A DEVIATION FROM THE BRIEF — ON EVIDENCE The task said nextcloud writes. The dataset says otherwise: of 270 G, 267 G is config_backup/, the rest is config/ (103 M) and config_old/ (3.4 G). There is NO data/ directory. This is the OLD non-k3s instance's configuration plus a backup blob — an archive — and that instance is STILL LIVE on it (exported rw to 192.168.1.6 and .5, which the operator has said must stay active). Two Nextclouds writing one instance's config directory, each with its own database and therefore its own oc_filecache, is unrecoverable corruption. "Do not grant more than needed" lands on ro, and ro is the trivially reversible choice. If the intent is in fact a MIGRATION, that is a larger and more deliberate change than a mount; the one-line flip is documented. Read-only for nextcloud can additionally be enforced SERVER-side (only nextcloud consumes that dataset from k3s), and the sharenfs value in the doc uses ro= for the k3s clients. The media tree cannot: plex and the arrs may land on any node, so the server sees the same addresses for reader and writers. Plex's ro is therefore a client-side guarantee — stated as a limitation, not left implied. Co-Authored-By: Claude Opus 5 <[email protected]> |

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

plex: add env vars (PLEX_UID/GID, TZ, ALLOWED_NETWORKS); homepage: rename Overseerr->Seerr
Plex Deployment had no Plex env vars. Add via the ServiceDefinition env list (rendered verbatim by catalog/render.py): - PLEX_UID/PLEX_GID=1000 (image chowns /config to this and drops; matches the Longhorn ownership convention seerr/semaphore use) - TZ=Etc/UTC (no other service sets TZ repo-wide) - ALLOWED_NETWORKS=10.0.0.0/8,192.168.0.0/16 so in-cluster clients (Seerr -> plex:32400) are trusted as LAN (pod CIDR 10.0.0.0/16 + svc 10.43.0.0/16 + LAN) PLEX_CLAIM intentionally not set (4-min TTL is unusable via git; one-time live claim persists on /config). ADVERTISE_IP deferred: the only candidate host resolves via split-horizon DNS to the internal Gateway VIP and its remote reachability is unverified — a wrong value breaks remote access, so omitted per prefer-safety, documented as a follow-up in catalog/plex.yaml. Homepage still labeled seerr as "Overseerr"; renamed the tile to "Seerr" (icon mdi-play-box-multiple keeps — not overseerr-specific). Co-Authored-By: Claude Opus 4.8 <[email protected]> |

fix(plex): mount config PVC at /config (image's real config dir)
The plexinc/pms-docker image writes its identity/claim token and the Library metadata DB under /config, but the config PVC was mounted at the renderer default /data/config. Plex therefore wrote all state to the container's EPHEMERAL layer: the server stayed UNCLAIMED (servers.plex.tv returns 401 with an empty X-Plex-Token) and lost everything on restart, which is why seerr's "add Plex" failed even with SSL off. Set the config volume mountPath to /config in catalog/plex.yaml and re-render apps/wave-0/plex.yaml (only the mountPath line changes; all other services byte-identical). No fsGroup/securityContext needed: verified in-cluster the image inits as root (s6-svscan PID 1), chowns /config to the plex user, then drops privileges (the "Plex Media Server" process runs as plex) — root can chown the mounted PVC regardless of fsGroup. PLEX_CLAIM auto-claim is intentionally NOT wired: the env secretKeyRef schema has no `optional`, so a placeholder/absent claim Secret would crashloop the pod. The claim is an operator step (UI sign-in after the roll, or add a PLEX_CLAIM env from a fresh https://plex.tv/claim token). 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.
Cutover: preceded by disabling prune on `apps` (
