 (b) the operator's path to a Gitea package token, (c) the DNS change
 path for `whywhynot.de`, and (d) any pre-condition gaps.
 
+**Findings (2026-05-18):**
+
+- **cnpg landscape — no shared cluster yet.** `kubectl get clusters.postgresql.cnpg.io -A` returns two
+  app-dedicated clusters in the `databases` namespace:
+  - `gitea-db`        — `ghcr.io/cloudnative-pg/postgresql:18.1-system-trixie`, 1 instance, 10Gi
+  - `net-kingdom-pg`  — `ghcr.io/cloudnative-pg/postgresql:16`,                  1 instance, 10Gi
+  Neither was provisioned as a shared cluster. The user's earlier choice
+  ("shared cnpg cluster, new database role") therefore requires a sub-decision —
+  see **Decision D-01** below.
+- **Gitea registry reachable.** `curl --resolve gitea.coulomb.social:443:92.205.130.254
+  https://gitea.coulomb.social/v2/` returns `HTTP 405` for `HEAD` with a valid TLS chain
+  (cert: `default/gitea-tls`, ready 3d). The OCI endpoint is up; HEAD-vs-GET is expected.
+- **Gitea package token — still required.** No package-capable PAT is currently held
+  by the operator in this session (carryover blocker from `RAILIANCE-WP-0001-T04`).
+  Token must be minted via the Gitea web UI by a user with `write:package` scope before T03.
+- **Public DNS for `whywhynot.de`:** A-record currently `217.160.0.212` (IONOS web hosting).
+  Authoritative NS = `ns1126.ui-dns.{de,biz,com,org}` (IONOS / 1&1). The zone is
+  administered through the operator's IONOS web console — DNS change is a manual
+  out-of-band step.
+- **Traefik LB public IP:** `92.205.130.254` (`kube-system/traefik` LoadBalancer service,
+  ports 80/443). This is the target the new A-record must point at.
+- **cert-manager:** `ClusterIssuer/letsencrypt-prod` is `Ready=True` (59d). Most recent
+  successful issuance: `default/gitea-tls`, 3d4h ago. Several stale failing certs in
+  `mfa` and `sso` namespaces are unrelated to this workplan.
+- **Pre-condition gaps before downstream tasks unblock:**
+  1. D-01 below (cnpg target cluster) — blocks T04.
+  2. Gitea package-capable PAT — blocks T03.
+  3. DNS A-record for `vergabe-teilnahme.whywhynot.de → 92.205.130.254` —
+     blocks T06.
+
+**Decision D-01 — cnpg target for `vergabe_db`** (pending; required before T04):
+
+| Option | Pros | Cons |
+|--------|------|------|
+| A. New dedicated cluster `vergabe-pg` | Matches the existing one-cluster-per-app pattern; clean blast radius | Resource cost grows linearly with apps; no actual "shared" cluster emerges |
+| B. Add role+db to existing `net-kingdom-pg` (PG 16) | Reuses a healthy PG 16 cluster matching vergabe-teilnahme's minimum; lowest cost | Cluster name no longer reflects its content; coupling with netkingdom domain |
+| C. Add role+db to existing `gitea-db` (PG 18) | Newest cluster image; same operator | Couples gitea ops with vergabe ops; name no longer reflects content |
+| D. Provision a new general-purpose cluster `apps-pg` (PG 16+) | Establishes a real shared cluster that future apps adopt | Net-new infra; needs a `railiance-platform` task to own the cluster |
+
+Recommendation: **D** (creates the "shared cluster" the user asked for as a real
+artifact rather than retrofitting an existing name). Recorded as a pending hub decision.
+
+**Resolution (2026-05-18, bernd):** Option D. Provision a new shared cnpg cluster
+`apps-pg` (PG 16, 1 instance, 10Gi initial) in namespace `databases`. cnpg `Cluster`
+CRs live in `railiance-platform` per ADR-003 (confirmed: `helm/gitea-db-cluster.yaml`).
+A coordination message has been sent to `railiance-platform` requesting the cluster.
+T04 below is now sequenced **after** that cluster reports healthy.
