+### CL-042: TASK22260 next slice — portal direct service partial endpointClient adoption
+
+date: 2026-03-25
+author: Cline
+scope: `actions/services/portalDirectService.js`
+type: change
+rationale: Continue phased client-layer adoption by migrating low-risk portal direct-service read/create paths to shared endpoint request helpers while leaving hash-sensitive delete/message flows unchanged.
+impact: Reduces duplicated axios response extraction on high-traffic portal retrieval paths and keeps hashed delete/message semantics stable.
+status: completed
+
+Summary:
+
+- Refactored selected `portalDirectService` functions to use shared endpoint client helpers:
+    - `getJson(...)` for read/listing routes (`getMyCases`, `getMyInvolvements`, `getMyLPACases`, representations, watched, awaiting submission variants)
+    - `requestJson(...)` for `createWatchedCases`
+- Preserved existing hash/delete/message flow implementations (`deleteMyRepresentations`, `deleteWatchedCases`, completion message functions) using existing axios + relay signing behavior.
+- Preserved existing catch-path logging behavior for all migrated functions.
+
+Validation:
+
+- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+
+Follow-ups:
+
+- Optional next bounded slice: migrate remaining non-hash POST helpers in `portalDirectService` (`setRepInvolvment`, `setCaseInvolvment`) to `requestJson` for full internal consistency.
