+## ✅ Test Failures Found & Fixed (Post-QA)
+
+After initial QA audit, full test suite execution revealed 3 test failures from legacy config removal:
+
+### Fixed Issues
+1. **test_unified.py::test_detect_unified_format** ✅ FIXED
+   - Cause: Test expected `is_unified` to be False for legacy configs
+   - Fix: Updated to expect `is_unified=True` always, validation raises ValueError
+
+2. **test_unified.py::test_backward_compatibility** ✅ FIXED
+   - Cause: Called removed `convert_legacy_to_unified()` method
+   - Fix: Test now validates proper error message for legacy configs
+
+3. **test_integration.py::TestConfigLoading::test_load_valid_config** ✅ FIXED
+   - Cause: Used legacy config format in test
+   - Fix: Converted to unified format with sources array
+
+### Kimi's Finding Addressed
+4. **pdf_extractor_poc.py undefined variable bug** ✅ ALREADY FIXED
+   - Lines 302, 330: `[l for line in ...]` → `[line for line in ...]`
+   - Fixed in commit 6439c85 (Jan 17, 2026)
+
+**Fix Results:** All 41 tests in test_unified.py + test_integration.py passing (1.25s)
