NB-076 cbffb843fb S12: Role-based user stories — 23 acceptance criteria, 43 tests 
6 roles, each with executable acceptance tests:
- Migration Engineer (4): classify MT01 1:1, IF-ELSE branches, 75/75 non-unknown, non-zero data
- QA Engineer (3): IF T/F both covered, EVAL distinct values, deterministic output
- System Integrator (3): COPYBOOK resolution, JCL parsing, FILE-CONTROL multi-SELECT
- Tech Lead (3): confidence ordering, contradiction detection, report metrics
- COBOL Expert (6): compound OR, VARYING AFTER, inline PERFORM, nested IF 5-level,
  real HINA001 program, EBCDIC/SJIS encoding
- Java Developer (4): JSON serializable, expected fields, per-FD output files,
  GnuCOBOL compile + run + output capture

"""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. Java Developer — receives test data, uses it to validate Java output
