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 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.

jakman85andClaude Opus 5 4c4f5355d9 fix(sso): postStart hooks must exit 0 — nextcloud crashlooped the moment OIDC ran
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
LIVE REGRESSION, caught on the reconcile after merging #5. nextcloud went
CrashLoopBackOff with FailedPostStartHook, 7 restarts, and apps-wave-1/2 stalled.

ROOT CAUSE — a latent bug that could never fire until now. The final statement of
nextcloud's postStart script was:

    [ "$p" -ge 15 ] && nextcloud_oidc_fail "could not promote ... after retries"

On the SUCCESS path (p < 15) the test returns 1, and as the script's LAST command that
becomes the hook's exit status. A non-zero postStart exit makes the kubelet KILL the
container. This was harmless for as long as the OIDC guard above it was dead code that
exited 0 first (see 3484955) — fixing that guard made the block execute for the first
time in these apps' deployed lifetime, and the bug fired immediately.

That is the honest sequence: the previous commit did not introduce this defect, it
UNCOVERED it. Two bugs stacked, and the outer one hid the inner one.

FIX: convert to a plain `if`, then `exit 0` explicitly, with a comment recording why.

Also made gitea's hook explicit. Its last statement already returned 0 on both paths, so
it was correct by accident of ordering; leaving one hook implicitly-safe and one
explicitly-safe invites exactly this class back. Both now end with an unconditional
`exit 0`, and both say why in-file.

Every failure path in both hooks still logs loudly to stderr AND writes a marker file on
the persistent volume, and deliberately does NOT crash the pod — the break-glass local
admin must stay usable. That contract is now actually honoured; before, the success path
was the one that crashed.

Fixed in catalog/ (the ServiceDefinitions are the source of truth) and goldens
regenerated; render==golden green, renderer selftest PASS.

jakman85andClaude Opus 5 3484955903 fix(sso): gitea + nextcloud OIDC bootstrap was DEAD CODE — envsubst ate the guard
Both ServiceDefinitions guarded their Keycloak OIDC registration with an UNESCAPED
braced expansion:

    if [ -z "${GITEA_OIDC_CLIENT_SECRET:-}" ]; then      # gitea
    if [ -z "${NEXTCLOUD_OIDC_CLIENT_SECRET:-}" ]; then  # nextcloud, then exit 0

apps-wave-0/1 both declare postBuild.substituteFrom: cluster-vars, and neither name is a
cluster-vars key — so Flux's envsubst substituted them away AT RECONCILE TIME, long
before the container ever ran. Verified in the LIVE cluster: the deployed Deployments
literally contain

    if [ -z "" ]; then

which is always true. The entire OIDC registration block has been skipped on EVERY boot
of both apps.

WHY NOBODY NOTICED: both apps DO have the provider registered — `gitea admin auth list`
shows keycloak/OAuth2/true and `occ user_oidc:provider` shows the keycloak provider.
Those live in each app's own database, persisted from an earlier successful registration.
SSO works today and DECISIONS-LOG is not wrong. But the idempotent re-registration is
dead, so any PVC rebuild, DB restore, or fresh cluster build comes up with NO OIDC and
only the break-glass local admin. A PROD BUILD FROM THIS REPO WOULD SILENTLY HAVE NO SSO
on gitea or nextcloud.

The irony: the surrounding code was hardened twice — see its own comments about a "silent
first-boot RACE", the verify-then-retry loops, the marker files. All of that hardening was
unreachable, because the guard above it always evaluated true.

Not a regression from the recent R-ENV-02 tokenization — introduced 2026-08-27 (8738871).

FIXED AT THE RIGHT SEAM: apps/wave-0/gitea.yaml and apps/wave-1/nextcloud.yaml are
RENDER-GENERATED, so the fix is in catalog/*.yaml and the goldens are regenerated.
Escaped to $${...}, the convention documented in clusters/base/apps-vms.yaml. Post-envsubst
the container now receives the intended `${VAR:-}` instead of `""`.

STRICT MODE WOULD NEVER HAVE CAUGHT THIS. Flux deliberately exempts default-providing
operators (-, :-, +, :+, =, :=, ?, :?) from StrictPostBuildSubstitutions, because they
"intentionally handle the unset case". So a targeted check was required.

MADE UN-REPEATABLE IN THE RENDERER: catalog/render.py gains a substitution-safety section
wired into emit(), so every render path refuses to emit a manifest containing a braced
expansion that is not exactly ${KNOWN_KEY} for a key read LIVE from cluster-vars (no
hardcoded copy to drift; unreadable => empty set => fail-closed). Dollar-runs are counted
properly ($$ is a literal $ to envsubst, so odd runs are flagged and even runs are not),
and indexed forms get their own hard-error message. Nine new --selftest assertions,
including the exact regression. Proven to bite: rendering the pre-fix catalog files from
HEAD now exits 1 with the precise diagnosis.

Sweep: the complete substituted surface was enumerated from every Kustomization's path.
catalog/ contains exactly TWO braced expansions and both were these bugs; every other
braced expansion on a substituted path is a declared cluster-vars key (zero typos, zero
undeclared names); existing $${UOS_URL} escapes verified intact.

Verified: --selftest PASS; canonical render is byte-identical to the committed apps/ for
all 10 onboarded services; the three L1 render checks pass.

NEXT RECONCILE: both pod templates change, so gitea (wave 0) and nextcloud (wave 1) roll —
strategy: Recreate on RWO Longhorn PVCs, so expect a brief single-pod outage each. The
OIDC block then executes for the first time in these apps' deployed lifetime. Both paths
are idempotent (gitea takes auth update-oauth on the existing id; nextcloud's
user_oidc:provider is create-or-update), so the expected result is a no-op re-write plus
the verify loop logging success. If the SOPS client secret ever diverged from Keycloak's,
this is when it gets corrected instead of silently left stale. Tail both pods after merge.

jakman85andClaude Opus 4.8 68690e5019 fix(net): allow SSO apps egress to keycloak backend (Cilium 1.20 CVE-2025-30162)
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 fe0ee698c4 fix(apps): reconcile goldens to one canonical render + enforce render==golden gate
The committed apps/ goldens were a MIX of two render flag sets: 8 services
were rendered with `--no-image-automation` (no image CRs) while gitea and
nextcloud carried stale ImageRepository/ImagePolicy CRs from a render WITHOUT
the flag. Neither single command reproduced all goldens, and the gate did not
catch it.

Part A — canonical render:
  python3 catalog/render.py --all catalog -o apps --wave-layout --no-image-automation
`--no-image-automation` is canonical: image automation is authored-but-DISABLED
(DECISIONS-LOG; image-reflector/-automation controllers not installed), and
every app was onboarded via this flag. Re-render drops the ImageRepository +
ImagePolicy objects from gitea + nextcloud only (52 line deletions, purely the
trailing image-automation blocks). No functional content changed — the
nextcloud postStart hardening and gitea OIDC hook are untouched.

Part B — enforcement:
  ci/render-golden.sh renders every onboarded catalog service with the canonical
  command into a temp dir and FAILS on ANY diff vs committed apps/ (missing
  golden or content drift), across all 10 services (not just the 3 L1 spot-checks).
  Not-onboarded catalog entries (keycloak, vm-demo) are excluded per DESIGN-waves.
  Wired as a required no-cluster stage in ci/gate.sh, ci/Makefile, and both the
  live (.gitea/workflows/gate.yml) and dormant (merge-gate.yaml) pipelines.

Proof: tampering a golden makes the stage exit 1 (blocks merge); reverting
restores exit 0. `make -C ci gate` green in the devcontainer.

jakman85andClaude Opus 4.8 7f86e1099b fix(nextcloud-sso): register post-logout redirect URI + harden admin promotion
Two SSO follow-ups the operator hit after Nextcloud OIDC login worked.

1. Sign-out "redirect failed". On logout user_oidc redirects the browser to
   Keycloak's end_session_endpoint with post_logout_redirect_uri=<Nextcloud
   base '/'> and client_id=nextcloud but NO id_token_hint (provider
   sendIdTokenHint=0). Keycloak then validates that redirect against the
   client's post.logout.redirect.uris attribute, which was empty -> "Invalid
   redirect uri" -> the operator's "redirect failed". Register
   https://nextcloud.home.keithjackson.dev/* on the nextcloud client
   (attributes.post.logout.redirect.uris). Applied live via kcadm and captured
   here so git stays authoritative (a RealmImport no-ops on the existing realm).

2. postStart step (d) mirrors platform-admins -> built-in admin group, but the
   previous single best-effort pass ran occ group:adduser once with output
   swallowed and no retry. At early boot (container Started ~9s after create)
   that call can transiently fail (DB / maintenance race), silently dropping the
   promotion until the next restart. Harden step (d) with a verify-and-retry
   loop (like step (c)): re-read group:list and re-add any platform-admins
   member still missing from admin until verified (bounded ~30s), no-op for
   existing members.

jakman85andClaude Opus 4.8 7f92adfac6 fix(nextcloud): allow SSRF to private IdP + promote platform-admins to admin
Task 1 — browser SSO "Could not reach OpenID Connect provider" (confirmed root
cause, not guessed). keycloak.home.keithjackson.dev resolves split-horizon to the
PRIVATE Cilium gateway VIP (192.168.1.53). Nextcloud's SSRF guard refuses its own
server-side HTTP requests to RFC1918 addresses, so user_oidc's discovery/JWKS/token
fetch AT LOGIN throws OCP\Http\Client\LocalServerException "violates local access
rules" -> surfaced to the user as "Could not reach the provider". Proven from the
live pod: nextcloud.log carries the exact LocalServerException from
DiscoveryService::obtainDiscovery with Guzzle option allow_local_address:false; a
Nextcloud-context IClientService->get() of the discovery URL returns
LocalServerException with the flag false and HTTP 200 with it true (A/B toggled).
The postStart (b) curl check passed regardless because it uses system libcurl, not
Nextcloud's guard — which is why the provider registered yet login still failed.

Fix (reproducible, survives pod rolls): the postStart hook now runs
`occ config:system:set allow_local_remote_servers --value=true --type=boolean`
right after the install/maintenance wait, on every start.

Task 2 — promote Keycloak `platform-admins` members to Nextcloud admins (#5).
user_oidc 8.11 has NO native group->admin mapping (occ user_oidc:provider offers
group PROVISIONING and a login WHITELIST only), so the hook mirrors the provisioned
`platform-admins` membership into the built-in `admin` group idempotently (occ
group:list --output=json parsed via php argv; occ group:adduser admin per member).
A user is promotable after their first OIDC login provisions them + the next pod
start (or one manual `occ group:adduser admin <uid>`). The LOCAL admin stays as
break-glass (docs/15).

apps/wave-1/nextcloud.yaml re-rendered from catalog (single-file render; byte-diff
confined to the embedded hook). Rendered hook passes `sh -n`; parse step validated
in-pod. `make -C ci gate` green (lint/l0/l1; conformance + spec-immutability skip:
no cluster / spec repo unmounted).

jakman85andClaude Opus 4.8 d34c639269 fix(oidc): make gitea + nextcloud OIDC login-source registration persist
The Keycloak OIDC postStart registration for gitea and nextcloud ran but
never persisted, leaving `gitea admin auth list` empty and nextcloud's
user_oidc with "No providers configured" despite the apps installing/
enabling and the client secret being present.

Two distinct root causes, confirmed by running the registration manually
against the live warm pods:

- nextcloud: a QUOTING BUG, not a race. The OCC() wrapper runs
  `su -c "php occ $*"`, which word-split `--scope="openid email profile"`
  back into three tokens, so occ saw `email profile` as extra positional
  args -> "Too many arguments to user_oidc:provider" -> exit 1, swallowed
  by `|| echo failed`. Failed on EVERY boot. Fixed by running the provider
  call as ONE `su -c` with the scope single-quoted so www-data's shell
  keeps it a single argument; keep the OCC() wrapper only for single-token
  subcommands.
- gitea: a first-boot RACE. The direct `admin auth add-oauth` persists once
  the app/network is warm (verified live), but fired too early at postStart
  and its failure was swallowed (`|| echo ... >&2`, exit 0).

Hardening applied to both catalog sources (rendered into apps/wave-*):
- wait (bounded ~90s) for the Keycloak discovery doc to return HTTP 200;
- nextcloud also waits for `installed: true` AND `maintenance: false`;
- register idempotently (create-or-update) then VERIFY the source/provider
  actually persisted, retrying the whole cycle (guards exit-0-but-nothing-
  stuck);
- on give-up, log LOUDLY to stderr AND a marker file on the persistent
  volume (/data, /var/www/html) instead of swallowing — next failure is
  visible;
- never crashloop: missing-secret guard retained, break-glass local admin
  stays usable.

jakman85andClaude Opus 4.8 f163026954 feat(nextcloud,semaphore): wire native Keycloak OIDC SSO (break-glass admins retained)
Extends the SSO work to the two remaining `auth: oidc` apps still on local-admin
logins, each as a native confidential client of the Keycloak `homelab` realm with
its local admin kept as break-glass (docs/15 availability caveat; R-IDP-02/06).

Realm (source of truth): add the `nextcloud` and `semaphore` confidential clients
to platform/keycloak/keycloak-realm-import.yaml (modeled on grafana/gitea) + their
NEXTCLOUD_CLIENT_SECRET / SEMAPHORE_CLIENT_SECRET placeholders. As before, a
KeycloakRealmImport no-ops on an already-existing realm, so both live clients were
ALSO created via kcadm (nextcloud e95049ed-ca10-4085-97d9-4bbef495fe61, semaphore
1835bfe9-b125-4026-8f69-33557519cf4a); the YAML keeps git authoritative.

Secrets (SOPS/age): add nextcloud-client-secret + semaphore-client-secret to
keycloak-realm-clients.sops.yaml (keycloak ns). Mirror the nextcloud secret as
oidc-client-secret into nextcloud-bootstrap (nextcloud ns). For semaphore, the
whole SEMAPHORE_OIDC_PROVIDERS JSON (which embeds the client secret) is held
encrypted as oidc-providers-json in semaphore-bootstrap (semaphore ns). All values
verified == the live clients; existing keys untouched; no plaintext in git.

App config (catalog source + re-render):
- nextcloud: add NEXTCLOUD_OIDC_CLIENT_SECRET env + an idempotent postStart hook
  that installs/enables user_oidc and runs `occ user_oidc:provider keycloak`
  (create-or-update; secret via --clientsecret-env so it never hits argv; occ as
  www-data; group provisioning on the `groups` claim). Syntax verified against the
  running user_oidc 8.11.0 on Nextcloud 31.0.14; su-to-www-data env passthrough
  verified. Missing-secret/not-installed guards prevent crashloops.
- semaphore: add SEMAPHORE_OIDC_PROVIDERS env sourced from the encrypted
  oidc-providers-json (provider_url=realm issuer/auto-discovery, redirect
  /api/auth/oidc/keycloak/redirect). Mechanism verified against semaphore v2.19.10
  source (util ConfigType oidc_providers env tag + OidcProvider struct + router
  redirect path); no kubelet service-link env collision.
apps/wave-1/{nextcloud,semaphore}.yaml re-rendered via
`render.py --no-image-automation` (diffs are env/lifecycle-only).

Verified: realm import Done=True/HasErrors=False and platform-config
Ready=True/Healthy=True (unchanged); edited realm YAML passes server dry-run; live
homelab clients now include gitea/nextcloud/semaphore; static gate (lint/l0/l1)
green. Browser SSO login for each still needs a human check.

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).
