"""code-to10 v6 A8：audit_loop_driver 缺口补测。
|
||||
|
||||
补测基线（v5 头 10023fb 全量覆盖率，audit_loop_driver.py
|
||||
496 语句缺 116 行，77%）：本文件只补下列纯函数分支，其余
|
||||
缺口行以全量复测为准：
|
||||
- 338：LoopState.rebuilds_used 属性。
|
||||
- 436、440：_normalize_failures 的非 str、非 dict 项回落
|
||||
（str(item) 作 check）。
|
||||
- 456-457：_as_result_map 的列表项映射（id/check + passed）。
|
||||
- 490-507：_validate_test_changes_local 的 modify_assertion
|
||||
双缺口、audit 未登记、add 放行、未知动作、非 dict 项。
|
||||
- 528-562：_classify_root_cause_local 的 proof/条款/多轮
|
||||
归因与 unknown 回落、非 dict 项跳过。
|
||||
|
||||
只加测试，不改生产代码；直接测纯函数本身（不 mock 被测
|
||||
代码、不加 no-coverage pragma、不 skip）。
