"""M1a 缺陷收口脚本（幂等，可重复执行）。
|
||
|
||
修复 selfcheck.py 暴露的 4 类真实缺陷：
|
||
1) json/*.json CRUD 契约：editable 必须是 3 个 .dspy URL、browserfields 必须非空
|
||
2) init.py：必须用 ServerEnv().get_module_dbname('pbl_blueprint') 取库名（禁硬编码）
|
||
3) selfcheck.py D 组「禁硬编码库名」误报：排除 scripts/ 与 tests/（自查脚本自身的
|
||
模式字符串、测试桩 fakedb 的形参默认值不属于业务代码硬编码）
|
||
4) selfcheck.py F 组「RBAC 路径无通配符」误报：只扫描注册路径字面量，
|
||
排除报错消息文本里的 %s
|
||
|
||
用法： python3 modules/pbl_blueprint/scripts/fix_m1a_defects.py
