"""S12: Role-based user stories — complete end-to-end acceptance tests Roles: 1. COBOL Migration Engineer — runs pipeline, needs correct classification + test data 2. QA Engineer — verifies test data covers all paths, comparison accurate 3. System Integrator — configures JCL/copybooks/Java project mappings 4. Tech Lead / Reviewer — reviews results, validates quality metrics 5. COBOL Language Expert — validates parsing: all statements, edge cases, encoding 6.
