-Per `docs/SecurityPractice.md` §7: request I1 "Reinforced" (dedicated node
-pool / sandboxed runtime) at minimum for the `qonto-assistant` deployment on
-`railiance01`, given tenant-confidential financial-data classification,
-internet reachability via the facade, and sole custody of the bank
-credential. I2 "Dedicated" (own namespace/keys) is worth considering; the
-placement decision belongs to whoever owns Railiance scheduling for this
-workload, not this repo.
+**2026-07-24:** Made the request concrete and reviewable (this task's own
+stated scope — not to implement scheduling itself). Delivered:
 
-**Depends on:** a Railiance-side placement decision — this task's job is to
-make the request concrete and reviewable, not to implement scheduling.
+- `deploy/k8s/qonto-assistant/` — dedicated namespace (not shared with
+  `activity-core`), `Deployment` at `replicas: 0` (meant to be scaled 0↔1 by
+  the facade, T05), `ClusterIP`-only `Service`, default-deny `NetworkPolicy`.
+  Modeled on `llm-connect`'s real deployment, tightened per
+  `docs/SecurityPractice.md` §7. Verified: `kubectl kustomize` renders all
+  six resources cleanly.
+- **CCR-2026-0009** (in `railiance-platform`, `status: proposed`) — a
+  workload-scoped Kubernetes-auth access lane into the existing
+  `tenants/binky/qonto-api` credential, since CCR-2026-0008 is human/OIDC
+  admin access only and unusable by a running pod. Mirrors CCR-2026-0003's
+  llm-connect pattern. Paired draft `ClusterSecretStore` also added. Both
+  validated against `schemas/credential-change-request.schema.yaml`.
+- `railiance/app.toml` — staged-promotion contract, `criticality = "critical"`
+  (mandatory human approval before Stage 2 exposure and Stage 3 promotion,
+  per the contract's own rule for production-critical workloads). Validated
+  against `railiance-cluster/schemas/railiance-app.schema.json`.
 
-Done when: a placement decision is recorded (even if the decision is "I0 for
-now, revisit before going live") and referenced back into this workplan.
+**Still pending, explicitly not this task's to resolve:** CCR-2026-0009
+needs platform-operator + binky-tenant-owner approval; the actual isolation
+tier (I1 vs I2) is Railiance's scheduling call once the manifests are
+reviewed; whether the facade (T05) co-locates in this namespace is assumed
+in `networkpolicy.yaml` but not yet decided.
