+### CL-021: TASK22229 P2-S2 Batch 2 (my-portal + representation relay GET cluster)
+
+date: 2026-03-24
+author: Cline
+scope: `pages/api/endpoint/{getmycases_api,getmyrepresentations_api,getwatchedcases_api,getawaitingsubmission_api,getrepresentations_api}.js`, `tests/phase21/endpoint-handler-contract.test.cjs`
+type: change
+rationale: Deliver second P2-S2 commit by migrating the next bounded portal/representation GET endpoint cluster onto shared `relayGet` while preserving route contracts.
+impact: Reduced duplicated relay boilerplate and aligned forwarding behavior with no intended response contract changes.
+status: completed
+
+Summary:
+
+- Migrated Batch 2 endpoints to `relayGet`:
+    - `getmycases_api.js` (preserved title mapping transform)
+    - `getmyrepresentations_api.js`
+    - `getwatchedcases_api.js` (preserved watched-case projection transform)
+    - `getawaitingsubmission_api.js` (preserved title mapping transform)
+    - `getrepresentations_api.js`
+- Updated phase21 endpoint contract tests for migrated handlers by mocking `relayGet` in guard/catch test paths.
