+

+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: Continue the branch-by-branch relay policy rollout by applying explicit policy posture to core my-portal retrieval endpoints.
+impact: Improves consistency and operational predictability of relay behavior for portal case/representation listing flows without changing endpoint contracts.
+status: completed
+
+Summary:
+
+- Added explicit `relayPolicy` declarations to:
+    - `getmycases_api`
+    - `getmyrepresentations_api`
+    - `getwatchedcases_api`
+    - `getawaitingsubmission_api`
+    - `getrepresentations_api`
+- Applied bounded read profile across the batch:
+    - `method: "GET"`
+    - `timeoutMs: 8000`
+    - `maxRetries: 2`
+    - `retryBaseDelayMs: 150`
+    - `retryMaxDelayMs: 800`
+- Extended phase21 endpoint contract tests with relayPolicy pass-through assertions for each endpoint.
+
+Validation:
+
+- `node tests/phase21/endpoint-handler-contract.test.cjs` -> pass (164/164)
+- `node tests/phase21/relay-forwarding-hardening.test.cjs` -> pass (10/10)
+- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+
+Follow-ups:
+
+- Optional next slice: extract shared relay policy presets into a constants module and reference them from all relayGet endpoints to reduce duplication.
