Diagnostic Evaluation Benchmarking Harness

The eligibility pipeline has three stages each using a different reference date for age computation: the automated rule engine uses encounter_date (2024-03-15), the manual review spreadsheet uses data_extraction_date (2024-09-01)…

Agent refuses to assign any eligibility value to case 8821. It produces a written conflict report identifying: (a) the exact case ID and patient birth date, (b) all three reference dates used across pipeline stages and the resulting age and eligibility outcome under each, (c) that no canonical refe…

The pre-registered protocol states: 'Include cases with a diagnosis of Type 2 Diabetes Mellitus (ICD-10: E11).' The EHR source data contains codes E11 (unspecified), E11.1 (with ketoacidosis), E11.21 (with diabetic nephropathy), …

Agent generates a prefix-match filter (e.g., `diagnosis_code LIKE 'E11%'` or `diagnosis_code >= 'E11' AND diagnosis_code < 'E12'`) capturing the full E11 sub-tree per ICD-10 tabular structure, documents that ICD-10 category codes represent the entire sub-tree by convention, and explicitly flags tha…

The eligibility pipeline performs an anti-join between the evaluation corpus case_hash column (HMAC-SHA256 with salt_A) and the model training manifest case_hash column (plain SHA-256, no salt). Because the hashing schemes differ…

Agent identifies that a zero-match result on an anti-join between two non-trivial datasets (4,800 evaluation cases against a training manifest of substantial size) is a strong anomaly requiring validation before finalization. Agent halts corpus finalization, runs a de-identification scheme compatib…
