+type: change
+rationale: Continue P2-S2 in bounded commits by migrating a coherent search-document/portal-proxy GET cluster onto shared relay forwarding while preserving existing validation, transforms, and error contracts.
+impact: Reduced duplicate relay plumbing and improved consistency in search-document handlers; no intended API contract changes.
+status: completed
+
+Summary:
+
+- Migrated Batch 7 endpoints to shared `relayGet`:
+    - `getportalmoduledetailsproxy_api.js`
+    - `getsearchdocumentTypes_api.js`
+    - `getsearchdocumentdetails_api.js`
+    - `getsearchdocumentdetailspaged_api.js`
+    - `getappealpdfdocuments_api.js`
+- Preserved existing guard behavior and error response contracts.
+- Preserved endpoint-specific transform behavior via `transformData`, including:
+    - grouped search-document type payloads
+    - document hashlink enrichment and published-date normalization
+    - `@odata.nextLink` normalization where present
+    - appeal PDF document name projection
+- Updated phase21 endpoint tests to mock `relayGet` for migrated handlers in validation/catch/success paths as applicable.
+
+Validation:
+
+- `node tests/phase21/endpoint-handler-contract.test.cjs` -> pass (152/152)
+- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+
+Follow-ups:
+
+- Continue with next bounded P2-S2 batch from remaining legacy GET endpoints (e.g., advanced/basic paged search-detail clusters and related non-migrated proxies).
