+**Completion notes (this slice):**
+
+- Implemented on feature branch created from `refactor`: `rep-slice-r6-data-service-cleanup`.
+- Added deterministic representation-specific data-resolution helpers in:
+    - `components/case/representation/utils/dataResolution.js`
+- Updated `components/case/representation/index.js` to use extracted helper functions for:
+    - initial case details/results source resolution
+    - details/results lookup by current context (state/edit/ticket/created)
+    - submit-path details source resolution and details lookup
+- Preserved slice boundary constraints:
+    - no service/API call execution movement
+    - no dispatch sequencing changes
+    - no loader branch redesign
+    - no blob retrieval orchestration changes
+    - no payload contract/Redux/route/query/EN-CY changes
+- Validation evidence:
+    - `npm run lint` completed (warnings only, no new errors).
+    - `npm run test:reps` completed: **7 passed**.
+    - Manual APP/IP/Agent/LPA checks: **passed**.
+    - Manual EN/CY parity checks: **passed**.
