+# Lane C backend pytest gates
+
+- [x] Add regression coverage for role policy matrix, RAG, diagnostic IAR states, quiz generation, risk/WRI, quiz battle API, and intervention pipeline.
+  CHECK: `python -m pytest tests/test_role_policies_regression.py tests/test_rag_regression.py tests/test_diagnostic_iar_states.py tests/test_quiz_generation_regression.py tests/test_risk_wri_regression.py tests/test_quiz_battle_api.py tests/test_intervention_pipeline.py -q`
+  EXPECT: All seven new test modules collect and pass. Evidence: 141 passed, 2 warnings, 0 failures (27.79s).
+- [x] Keep production code and existing test fixtures unchanged by Lane C.
+  CHECK: `git status --short -- backend/gates-leaf-lane-c.md backend/tests/test_role_policies_regression.py backend/tests/test_rag_regression.py backend/tests/test_diagnostic_iar_states.py backend/tests/test_quiz_generation_regression.py backend/tests/test_risk_wri_regression.py backend/tests/test_quiz_battle_api.py backend/tests/test_intervention_pipeline.py backend/main.py backend/routes backend/tests/conftest.py`
+  EXPECT: Lane C changes are limited to this gate file and the seven new test modules; existing unrelated dirty files are preserved.
+  Evidence: status showed the seven new modules and gate file, plus pre-existing dirty `backend/main.py` and `backend/routes/at_risk_resolution.py`; neither production file nor `conftest.py` was edited in Lane C.
+
+Gate-check script evidence: `gate-check.mjs` was not present in the workspace, so the prescribed automated gate-check could not be run; pytest and the scoped status check above are recorded directly.
