"""B1b 跨进程互认比对器：读两次独立运行的两份输出，字节相等才算"同参同指纹"。
用法：
python scripts/contract_interop.py --out reports/a.json
python scripts/contract_interop.py --out reports/b.json
python scripts/contract_interop_final.py --a reports/a.json --b reports/b.json --out reports/contract_v1_interop.json
判据：exit 0 = 两次运行字节一致 + I1–I4 全绿。
