+## Rollback Note
+2026-04-10: Rolled back from step 8 (New Task) to step 2 (Test Spec).
+Reason: All 9 expected result CSV files in _docs/00_problem/input_data/expected_results/ contain headers only — zero data rows. results_report.md has "?" for detection counts. Phase 1 and Phase 3 BLOCKING gates were not enforced. E2E tests cannot verify detection accuracy without ground truth data.
