jakman85andClaude Opus 5 4080065aa7 feat(dns): exposure: internal can no longer publish a public record
docs/09 R-DNS-03 and schemas/renderer-contract.md both said an `internal`
service renders no public DNS record. Nothing enforced either sentence.
ExternalDNS's `gateway-httproute` source admitted EVERY HTTPRoute on the shared
Gateway, so six `exposure: internal` services — jackett, pihole, qbittorrent,
radarr, semaphore, sonarr — published `<name>.home.keithjackson.dev` into the
public authoritative Cloudflare zone answering with the Gateway VIP
192.168.2.20. That published the internal subnet, the Gateway VIP and a full
service inventory to anyone who could guess a label, and made each of those
names a DNS-rebind primitive — which is why the SOHO router strips RFC1918
answers and LAN clients need per-client dnsmasq overrides to reach their own
services.

THE MECHANISM, established against the DEPLOYED version rather than from
memory. The live prod Deployment runs
registry.k8s.io/external-dns/external-dns:v0.21.0. In v0.21.0,
source/annotations/processors.go IsControllerMismatch() skips a source object
whose `external-dns.alpha.kubernetes.io/controller` annotation is present and
!= its own `dns-controller`, and source/gateway.go applies that check inside
Endpoints() BEFORE any hostname is resolved; source/service.go applies the
identical check, covering the second configured source. catalog/render.py now
emits that annotation on every HTTPRoute it renders for an `internal` service,
derived from `exposure` alone — no per-service list — so a service that omits
`exposure` inherits the internal default and is unpublishable too. Verified
LIVE on prod on a throwaway hostname with no existing record at risk: the
annotated route published nothing, and adding the annotation to a route that
already had a record produced action=DELETE for both its A record and its `a-`
TXT registry entry one ~60s reconcile later, moving nothing else in the zone.

WHY PER-RESOURCE AND NOT A CLUSTER-WIDE OPT-IN FILTER. `labelFilter` is the
stronger default posture and v0.21.0 supports it for both configured sources,
but nine publishing objects here are hand-authored platform/apps manifests with
no `exposure` field, seven of which hold live records (auth, crafty, crafty-mc,
grafana, headlamp, the apex, unifi). An opt-in filter deletes all seven at
once, and whether each should be publicly resolvable is an operator decision
per name. Per-resource exclusion has exactly the blast radius of the defect;
the seven are enumerated in a shrink-only register so the unadjudicated set
cannot grow silently, and the filter stays available as hardening afterwards.

`policy: sync`, `txtOwnerId` and `domainFilters` are UNTOUCHED. Per-resource
exclusion only ever removes an object from this instance's view, so nothing
here makes prod capable of deleting a record it does not own.

WHAT THIS DELETES, and it is not reversible by a revert alone: 12 records — the
A record and the `a-`-prefixed TXT registry entry for each of jackett, pihole,
qbittorrent, radarr, semaphore and sonarr. The zone has no
`*.home.keithjackson.dev` wildcard and `*.keithjackson.dev` does not match two
labels, so each becomes a public NXDOMAIN with no fallback. The complete
pre-state is captured at the authority and committed as a recovery baseline
(.standup-dns/dns-20260914-pre-externaldns-scope.txt), with the restore
procedure for both halves of a record.

MERGE ORDER IS NOT OPTIONAL: feat/pihole-lan-dns-authority must land and be
verified first. Removing these records while the LAN still depends on them,
with the router stripping RFC1918 and no internal authority yet, breaks name
resolution outright.

The five `exposure: public` services are LEFT UNCHANGED and still answer with
the Gateway VIP, so they remain publicly unreachable. That is two open operator
decisions, both written up in platform/externaldns/helmrelease.yaml: what
address they should answer with (136.51.115.252 is the legacy non-k3s stack
serving a placeholder cert, not established as correct for this cluster), and
how to separate them from the non-public names that share the Gateway —
because in v0.21.0 the target annotation is read only from the GATEWAY and a
ListenerSet, never from an HTTPRoute, so a per-service override is not
expressible while they all attach to `shared`. No knob is added for it yet: one
that cannot take effect invites someone to set it and expect one.

Guard: conformance/tests/l0-static/internal-services-publish-no-public-dns, a
whole-repo-scoped L0 static check (no ci/l0.sh stage — the
whole-repo-invariants-wired meta-test forbids one). It asserts both directions
(present on internal, absent on public), the `service`-source half, that the
renderer DERIVES the annotation from `exposure` and cannot emit external-dns's
own claiming value, proves the shipped renderer end-to-end on
internal/public/omitted-field fixtures, and ratchets the non-catalog register.
Proven to fail on the pre-fix tree (9 of 53 assertions, naming all six
services) and pass after (56/56).

Schema 1.6.0 -> 1.7.0: no field changes, a mapping change to `exposure`.

jakman85andClaude Opus 5 cf7d97e546 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.

jakman85andClaude Opus 5 5da116b34d fix(oauth2-proxy): platform-admins may reach the media UIs — the immediate 403
The four forward-auth media UIs (jackett, qbittorrent, radarr, sonarr) gate on
`--allowed-group=media-users` alone. On prod the `homelab` realm has exactly one
user — the operator's `jakman85` — and it is a member of `platform-admins` ONLY.
`media-users` has zero members, so those four hosts were reachable by nobody:
oauth2-proxy completed OIDC discovery, redirected to Keycloak, got a token whose
`groups` claim is `["platform-admins"]`, found no allowed group in it, and
answered 403. No login form appeared because the browser already held a Keycloak
SSO session from a platform-admins login — hence "403 immediately".

pihole and crafty were unaffected: they already gate on platform-admins.

`--allowed-group` is repeatable and OR-ed, so listing both groups means "media
consumers OR platform operators". This grants no real privilege — platform-admins
already maps to cluster-admin via k8s-oidc-rbac.yaml (oidc:platform-admins), so a
member can already exec into these pods — and it keeps media-users meaningful for
non-admin household accounts.

Ruled out while diagnosing: client-secret drift (all 7 sidecar secrets hash-match
keycloak-realm-clients), stale apex URLs (every live sidecar carries
keycloak.prod.home.keithjackson.dev), missing group mappers (all 7 clients emit
claim=groups, full.path=false), and the central oauth2-proxy pod restarts — those
were Keycloak returning 503 "no healthy upstream" to OIDC discovery at startup, a
consequence of the Keycloak roll, not a cause.

Goldens re-rendered with the canonical command:
  python3 catalog/render.py --all catalog -o apps --wave-layout --no-image-automation

jakman85andClaude Opus 5 6b953cc56b fix(arrs): the config PVC was mounted where the app never looks
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
sonarr, radarr, jackett and qbittorrent all mounted their Longhorn config PVC at
the renderer's default /data/config, but every one of these images runs with
`-data=/config`. So the PVC held nothing but lost+found while the app wrote its
entire configuration to the container's EPHEMERAL writable layer — destroyed on
every pod recreation: restart, reschedule, image bump.

Measured in-cluster before fixing, per app, rather than inferred:
  /data/config  dev=2080  [lost+found]                      <- the Longhorn PVC
  /config       dev=2053  [Sentry asp config.xml logs ...]   <- the node's own disk
and a marker file written to /config did not appear in /data/config, so they are
demonstrably different storage. qbittorrent's /config sat on dev=66309
(/dev/nvme0n1p5), i.e. whichever node it happened to land on.

This is the SAME failure catalog/plex.yaml:54 already records having fixed for
Plex; plex was the only one of the five that was right.

The live /config contents were copied onto each PVC BEFORE this landed, so
jackett's API key and qbittorrent's credentials — which other apps reference —
survive the move rather than being regenerated.

catalog/sonarr.yaml:61 documented this as a latent bug and deliberately left it
because it changes live on-disk state. It is being fixed now because all four pods
had just been recreated, so their configs were freshly generated and nothing had
accumulated to lose.

jakman85andClaude Opus 5 82aff4d053 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.

jakman85andClaude Opus 5 c8c1d2935d feat(dns): per-environment BASE_DOMAIN — prod moves to its own subdomain
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
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.

jakman85andClaude Opus 4.8 b2752aec48 feat(auth): gate jackett/qbittorrent/radarr/sonarr UIs with oauth2-proxy sidecar (rollout)
Roll the verified Option-B per-app oauth2-proxy sidecar out to the remaining
four forward-auth apps after the pihole canary was confirmed fail-closed
(unauthenticated -> 302 to Keycloak, pod 2/2, clean sidecar OIDC discovery).

Each app's Gateway route now terminates at its oauth2-proxy sidecar (:4180,
--allowed-group=media-users, --upstream=http://127.0.0.1:<uiport>); the
gateway-ingress CiliumNetworkPolicy allows the Gateway to reach ONLY :4180, so
the bare UI is never served un-authenticated (fail-closed; R-IDP-02/06). The
apps' own app/API ports stay in-Service for EAST-WEST callers (arr ->
qbittorrent:8080 / jackett:9117) via the existing reciprocal-ingress allows.

- keycloak: confidential jackett/qbittorrent/radarr/sonarr clients (realm-import
  + realm-clients mirror), provisioned live via kcadm (groups membership mapper).
- secrets: four SOPS/age <app>-oauth2-proxy-credentials, wired into apps/wave-0
  and apps/wave-1 by the renderer's sidecar-creds wave rule.
- ci: remove the temporary canary deferral (all five goldens now reproduce).

App SSO broke cluster-wide after the Cilium 1.16.5->1.20.1 upgrade: the CVE-2025-30162 fix (in
>=1.16.8/1.17.2) makes the shared Gateway's L7 proxy re-evaluate a pod's egress policy against
Keycloak's REAL backend cluster identity (enforce_policy_on_l7lb) when it hairpins to keycloak.home.
'toEntities: world' matches the Gateway VIP at L3/L4 but not the resolved keycloak identity at L7, so
OIDC discovery/token 403'd ('Access denied') for every app with a NetworkPolicy (gitea/nextcloud/
semaphore/headlamp/crafty...); Grafana survived only because monitoring has no NetworkPolicy.

Fix: explicit toEndpoints egress allow to the keycloak backend for SSO apps.
- catalog/render.py: emit it for auth.mode in {oidc,forward-auth}; re-rendered 8 app goldens.
- platform/headlamp + platform/crafty: hand-written policies get the same allow.
Split-horizon design unchanged. Verified live: headlamp-ns -> keycloak discovery 403 -> 200.

jakman85andClaude Opus 4.8 36a1a4e1f9 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` (1bfb0db) so removing that
object here does not GC its resources; the wave Kustomizations SSA-adopt the
byte-identical manifests in place (no restart, no PVC churn).
