+## Ask #2 — postgis k8s toolchain runner — DONE (proven via the preflight gate)
+Added the **`seaspots-postgis-utils`** host-mode runner on crunchy k3s (id 7,
+`foundation-runner-k8s-postgis`), Pulumi-codified in `runners-k8s/` alongside s57.
+- **Combined image** `foundation/seaspots-postgis-runner:1.1.1` = the stock
+  `seaspots-postgis-utils:1.1.1` (postgis/postgis:18-3.6, Debian trixie) + git + node20 +
+  forgejo-runner. Built on the forge VM (docker+buildx, gitlab creds from the crunchy
+  gitlab-ns pull secret), streamed `docker save | gzip` → `k3s ctr images import` to crunchy
+  (forge can't reach crunchy's private IP → relayed through the workstation). Build-time
+  `RUN node --version && …` confirmed the bookworm node binary runs on trixie.
+- **Reused the uid-10001 securityContext** (no index.ts uid change): the postgis base is built
+  to run as any uid, and the job points `PGDATA`/`OUTPUT_DIR`/`ENC_DIR` at the writable
+  `/scratch` PVC. `toolchains` entry: postgis 4 CPU / 8 Gi / 50 Gi. `pulumi preview` was purely
+  additive (+2, 8 unchanged — s57 + shared token/ns untouched); `pulumi up` = runner online.
+- **Preflight quality gate (operator's ask):** `citest-fenced` task 107 on runner 7, green —
+  runs the image's own `/app/entrypoint.sh preflight` (tools, SQL files, ENC cells, writable
+  dirs, ≥20 GB disk, PG 18.3 smoke test) against a dummy `.000` cell on `/scratch`. Seconds, not
+  the 40-60 min build; writes ~nothing (sidesteps the node-disk risk too). crunchy `/` had
+  **408 GB free** (52%) — the disk risk was far smaller than the earlier 214 GB estimate.
+- Committed `feat(runners-k8s): postgis toolchain runner + preflight quality gate`. Forge-VM
+  build hygiene: gitlab creds removed from `/root/.docker/config.json` (backup restored), build
+  images dropped.
+
+## NEW operator ask (end of session) — MinIO/S3 creds for the data pipelines
+The postgis/tiles tooling needs `AWS_ENDPOINT_URL` (minio.wob.olsitec.de), `AWS_ACCESS_KEY_ID`,
+`AWS_SECRET_ACCESS_KEY` — currently GitLab **group** CI/CD variables. Recommendation (mirrors the
+ci-bot pattern): **org-level Forgejo Actions secrets** as the CI runtime source (`AWS_ENDPOINT_URL`
+can be a non-secret org *variable*), set via the Actions API like `FORGE_REGISTRY_*`; reusable
+workflows read them via `secrets: inherit` (quirk 4). **Vault = optional backup + human
+source-of-truth** with an idempotent provisioning step that pushes them to the org secrets — never
+a hard CI dependency (same trap we avoided for ci-bot). Values must come from the operator (or
+Vault); NOT started — awaiting the creds.

 ## Still open
-- **Ask #2** — postgis/osm k8s toolchain runners (s57 done). Operator note: the runner scripts
-  have a **pre-flight-only** mode — use it as the CI quality gate so test jobs don't run the full
-  40–60 min pipeline. NEXT.
+- **osm k8s runner** — no active pipeline yet; recipe in `runners-k8s/README.md §Adding another toolchain`.
+- **MinIO creds** — provision the org Actions secrets once the operator supplies values (see above).
 - **DR/backlog (carried):** `runners`/`runners-k8s` stack state not backed up; T15; hardening
   (Forgejo v15 upgrade would drop quirks 1–2 and may add container auto-link → revisit the
   SHA-pin + explicit-link once upgraded).
