+### CL-052: TASK22260 next slice — portal direct service requestJson parity for config-based reads/deletes
+
+date: 2026-03-25
+author: Cline
+scope: `actions/services/portalDirectService.js`
+type: change
+rationale: Continue bounded direct-service consistency by migrating remaining config-based portal helper calls from `axios(config)` to shared `requestJson(...)` where no signed-delete/header-specific behavior is required.
+impact: Reduces repeated config execution/response extraction boilerplate and improves request helper consistency in portal service while preserving behavior.
+status: completed
+
+Summary:
+
+- Migrated selected config-based helpers to `requestJson(config)`:
+    - `deleteAwaitingSubmissions`
+    - `sendCaseCompleteMessage`
+    - `sendCaseCompleteMessageProxy`
+    - `sendRepCompleteMessage`
+- Preserved behavior contracts:
+    - unchanged query/hash composition and request methods
+    - unchanged catch-path logging via `consoleLogger`
+    - left signed delete helpers with bespoke axios/header behavior unchanged (`deleteMyRepresentations`, `deleteWatchedCases`)
+
+Validation:
+
+- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+
+Follow-ups:
+
+- Optional next bounded slice: assess whether signed-delete helpers in `portalDirectService` should remain explicit axios calls (for clarity on headers/hash semantics) or move to a dedicated signed-request client helper.
