+### CL-047: TASK22260 next slice — case direct service low-risk getJson adoption
+
+date: 2026-03-25
+author: Cline
+scope: `actions/services/caseDirectService.js`
+type: change
+rationale: Continue incremental endpoint client rollout with a bounded low-risk set of case service GET helpers that already return direct JSON payloads and have simple logging-only catch paths.
+impact: Reduces repeated axios GET/response extraction boilerplate and aligns additional case retrieval helpers with shared client conventions.
+status: completed
+
+Summary:
+
+- Added `getJson` usage in selected `caseDirectService` helper functions:
+    - `getAppealPDFDocs`
+    - `getPortalModuleDetails`
+    - `getPortalModuleDetailsProxy`
+- Preserved existing behavior contracts:
+    - same request URL/query construction
+    - same catch-path logging via `consoleLogger`
+    - no change to handlers with bespoke error-return contracts (`getAppealPDFDocument`) or other non-targeted flows.
+
+Validation:
+
+- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+
+Follow-ups:
+
+- Optional next bounded slice: migrate additional safe case service GET helpers that currently use `axios.get(...).then(res.data)` to `getJson` where custom catch behavior is compatible.
