tests/attack_forged_callid.py — 越狱测试 c：伪造 callId 的成果报告（Agent-C）
==========================================================================

  C1) 纯伪造：报告引用从未签发的 call-uuid → validate_report_citations 必须
      valid=False 且 missing 精确等于伪造 id。
  C2) 混淆伪造：伪造 id 与真实 id 混排 → 仍须 invalid，且真实 id 不受影响。
  C3) 真实运行复核：对真实 LLM 链路（realchain 最新一次）产出的报告与
      calls.jsonl 再跑一遍校验 → 必须 valid=True（真实凭证不应误判）。

退出码 0 = 全部按预期；2 = 校验器失效。
