 | Decision | Choice | Rationale |
 |----------|--------|-----------|
 | **Cluster** | [[ringtail]] (k3s) | IdP independent of main services cluster, same as Dex |
-| **Database** | CNPG `blumeops-pg` on [[indri]] | Cross-cluster via Tailscale, no new operator needed |
+| **Database** | CNPG `blumeops-pg` on [[indri]] | Cross-cluster via Caddy L4 (`pg.ops.eblu.me`), no new operator needed |
 | **Redis** | Co-deployed in authentik namespace | Required for caching/sessions/task queue |
 | **Containers** | Nix-built (`dockerTools.buildLayeredImage`) | Supply chain control, consistent with Dex/ntfy pattern |
 | **Manifests** | Kustomize (no Helm) | Consistent with all other BlumeOps services |
 | **Networking** | Tailscale Ingress + Caddy reverse proxy | Same pattern as Dex |
 
-## Open Questions
+## What Was Done
 
-- ~~**nixpkgs:** Verify `pkgs.authentik` exists.~~ **Resolved:** exists at v2025.10.1, entrypoint is `ak` (bash wrapper). See [[build-authentik-container]].
-- **Cross-cluster metrics:** Prometheus on indri scraping authentik on ringtail needs a new pattern (Dex has no metrics collection today).
-- **Dex decommission:** Separate effort after all OIDC clients migrate to Authentik.
+1. Built Nix container image (`v1.1.0-nix`) — `pkgs.authentik` + `coreutils` + `bashInteractive`
+2. Created 1Password item "Authentik (blumeops)" with secret key and DB credentials
+3. Provisioned `authentik` database and CNPG managed role on `blumeops-pg`
+4. Deployed to ringtail k3s: server, worker, Redis (3 deployments)
+5. ExternalSecret pulls config from 1Password
+6. Tailscale Ingress at `authentik.tail8d86e.ts.net`
+7. Caddy reverse proxy at `authentik.ops.eblu.me`

+## URLs

+- **Admin:** https://authentik.ops.eblu.me/if/admin/
+- **Tailscale:** https://authentik.tail8d86e.ts.net
+
+## Remaining Work
+
+- **Initial setup:** Complete first-run wizard (create admin account)
+- **Forgejo connector:** Configure OAuth2 source for Forgejo federation
+- **Client migration:** Move Grafana (and future services) from Dex to Authentik
+- **Cross-cluster metrics:** Prometheus on indri scraping authentik on ringtail
+- **Dex decommission:** Separate effort after all OIDC clients migrate
+- **Redis image:** Replace upstream `redis:7-alpine` with Nix-built container
