oauth2-proxy read the base64 cookie value as raw bytes (44) → 'must be 16/24/32 bytes'
crashloop. Regenerated cookie-secret as openssl rand -hex 16 (32 bytes). client-id +
client-secret unchanged (still match the realm oauth2-proxy client). Value tracked in
~/.config/home-k3s/keycloak-sso-secrets.txt.

Generate the 3 OIDC client secrets (SOPS-encrypted, minimal manifests) so the realm
import can inject the grafana + oauth2-proxy client secrets and both consumers match:
- platform/keycloak/keycloak-realm-clients.sops.yaml (grafana + oauth2-proxy client secrets)
- platform/oauth2-proxy/oauth2-proxy-credentials.sops.yaml (client-id/secret/cookie)
- platform/monitoring/grafana-oidc-credentials.sops.yaml (grafana client secret)
Wire each into its component kustomization and re-enable oauth2-proxy in platform +
platform-config (reverses the temp deferral now that its secret exists).
Values generated by PM per operator instruction (random; recorded out-of-repo at
~/.config/home-k3s/keycloak-sso-secrets.txt for later rotation). Encrypted via sops in the
dev container to the age recipient in .sops.yaml; plaintext never committed.
Serves: R-IDP-01, R-IDP-02, R-IDP-04, R-SEC-01.

Enable monitoring in platform/kustomization.yaml (Phase 4). Grafana admin +
Alertmanager SMTP secrets are provisioned (SOPS) and wired; Longhorn SC is up for
Prometheus/Loki PVCs. Set the Alertmanager receiver 'to:' to a valid inbox
([email protected]) so the config loads (REPLACE-ME is not a valid address);
operator can change it. NOTE: smtp_from ([email protected]) differs from
the Gmail auth user — Gmail may reject/rewrite unless a send-as alias is configured;
that only affects email delivery at alert time, not stack health.
