Semaphore's whole SEMAPHORE_OIDC_PROVIDERS JSON blob lived inside the SOPS-encrypted
semaphore-bootstrap Secret (key `oidc-providers-json`) because it CONTAINS the confidential
client secret. That buried two environment-specific, NON-SECRET URLs in ciphertext —
provider_url (the realm issuer) and redirect_url — where Flux's ${BASE_DOMAIN} postBuild
substitution cannot reach. Both were frozen at `home.keithjackson.dev`, so prod's Semaphore
was pointed at dev's Keycloak and dev's own redirect URI: identical root cause to the
Headlamp login timeout, not yet reported only because nobody had tried prod SSO.
FIX: split the blob. The URLs are public and now live as a plaintext literal in
catalog/semaphore.yaml (rendered to the apps/wave-1 golden), ${BASE_DOMAIN}-substituted like
every other hostname. Only the client secret stays encrypted, in its own key
`oidc-client-secret`, and the KUBELET splices it back via dependent-env-var expansion:
$(SEMAPHORE_OIDC_CLIENT_SECRET) resolves against the secretKeyRef env var declared
immediately above it (order is load-bearing — the kubelet resolves env in list order and
leaves a forward reference as literal text).
Verified: the new key holds the same value as keycloak-realm-clients/semaphore-client-secret
(the mirror invariant), Semaphore v2.19.10's util.OidcProvider consumes client_secret as
before, and `flux envsubst --strict` leaves $(...) untouched while resolving ${BASE_DOMAIN} —
dev renders keycloak.home.keithjackson.dev, prod keycloak.prod.home.keithjackson.dev.
apps/wave-1/semaphore.yaml is a render golden; regenerated with the canonical
`catalog/render.py --all catalog -o apps --wave-layout --no-image-automation`.

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.

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).
