aps-agent/tests/golden/test_fallback_p4_injection.py

# ============================================================
# P4 注入防护 golden（Agent-C2，全部确定性；零真实 LLM/网络）。
# 覆盖 P4-P5-DESIGN §3 I-01..I-26 中已产品化的稳定攻击面：
#   用户 prompt 包裹与零写、CSV/inbox 数据不直写、伪 callId、
#   伪已确认/伪审批、路径逃逸、未登记工具/越界写事件、
#   凭证与诊断 secret 脱敏、白名单缺失 fail-closed、
#   status 伪状态行不得触发邮箱执行（I-25 只锁零越权写）。
# 手法与既有兜底 golden 一致：FakeStore + fake runner 注入
# propose_reply(runner=...)，PiBridge/fallback_highrisk/guard
# 只做确定性单元断言；不依赖真实 node/pi/网络/LLM。
