- 路径参数 ID 白名单（runs/agent/sessions），杀灭 Windows 反斜杠穿越（..%5C 直读 .env） - artifacts 端点关押 + pipeline 工件名消毒（模型输出名剥路径成分） - /llama/download dest 关押 models/ 内 + URL 协议白名单（先于 HF 别名转换） - GET /config architect.api_key 打码（api_key_set + 前 6 位），PUT 空串=保留 - TrustedHostMiddleware 信任围栏（GATEWAY_TRUSTED_HOSTS 可覆盖）+ __main__ 默认 127.0.0.1 - review 抽样改 CSPRNG - 新增 tests/test_security_hardening.py（13 项，全部离线）

"""安全加固测试（T30，Mimosa 扫描驱动）：
|
||
|
||
覆盖：
|
||
- 路径参数 ID 校验（防 Windows 反斜杠穿越 ../..%5C 变体）
|
||
- artifacts 工件名关押（防 ..\\ 越界读任意文件，如 .env）
|
||
- GET /config 密钥打码 / PUT 留空保留（对齐 D2）
|
||
- Host 信任围栏（防 DNS rebinding，dsh browser-auth 同款）
|
||
- pipeline 工件名消毒（模型输出名含 ../ 时不得越界写盘）
|
||
- llama 下载 dest 关押 + URL 协议白名单
|
||
- run_command 危险命令拦截（审批之外的独立防线）
|
||
- web_fetch SSRF 防护（私网/环回/协议白名单，全部离线可测）
