103+
- `*.key`
104+

105+
- `.ruff_cache/`
106+
- `pyrightconfig.json` 新增排除:
107+

111+
112+

113+
114+
## 三、验证结果
115+
116+
### 1) Pyright 全量验证
117+
118+
命令:
119+
120+
```bash
121+
python3 -m pyright --outputjson
122+
```
123+
124+
结果:
125+
126+
- `filesAnalyzed`: 110
127+
- `errorCount`: **0**
128+
- `warningCount`: **618**
129+
130+
> 说明:剩余 warning 主要集中在历史高噪音模块(如 `parsers.py`, `launcher/*`, `network.py`),已不影响“Error 清零”目标。
131+
132+
### 2) 关键回归测试(本次改动相关)
133+
134+
命令:
135+
136+
```bash
137+
python3 -m pytest \
138+
tests/api_utils/test_context_init.py \
139+
tests/api_utils/test_dependencies.py \
140+
tests/api_utils/routers/test_chat.py \
141+

142+

tests/browser_utils/page_controller_modules/test_parameters.py \
146+
tests/browser_utils/page_controller_modules/test_chat_controller.py -q
147+
```
148+
149+
结果:
150+
151+
- **196 passed**, 8 skipped, 0 failed ✅
152+
153+
---
154+
155+
## 四、TODO 完成状态
156+
157+
### P0 - 紧急(目录清理)
158+
159+
- [x] 删除空目录问题(`errors_py/.gitkeep`
160+
- [x] 删除 `deprecated/`
161+
- [x] 删除 `deprecated_javascript_version/`
162+
- [x] 删除 `utils/`
163+
- [x] 清理 `__pycache__/`
164+
- [x] 删除 `.DS_Store`
165+
166+
### P1 - 高优先级(核心代码类型)
167+
168+
- [x] `api_utils/context_types.py`
169+
- [x] `api_utils/dependencies.py`
170+
- [x] `api_utils/context_init.py`
171+
- [x] `browser_utils/page_controller_modules/parameters.py`
172+
- [x] `browser_utils/page_controller_modules/input.py`
173+
- [x] 路由层(`chat/queue/health/server/static`)类型修复
174+
175+
### P2 - 中优先级(测试类型)
176+
177+
- [ ] 测试类型体系全面重构(本次未做全仓测试类型重构)
178+
179+
### P3 - 低优先级(代码质量)
180+
181+
- [x] 更新 `pyrightconfig.json`(补充排除目录)
182+
- [x] 更新 `.gitignore` 建议项
183+
- [ ] `pass` 语句全仓人工审查(本次仅修复关键不可达异常分支)
184+
- [ ] 全仓 unused 彻底清零(仍有历史 warning)
185+
- [ ] `baseline_pyright.txt` 处置决策(保留由你决定)
186+
187+
---
188+
189+
## 五、后续建议(可继续超额)
190+
191+
如果你要我继续“打到极致”,下一步建议:
192+
193+
1. 针对 warning Top 文件继续压降(`parsers.py`, `launcher/process.py`, `network.py`
194+
2. 统一 `launcher/*``stream/*` 的异常/队列类型层
195+
3. 逐步把 warning 从 618 再降到 <200
196+
197+
---
198+
199+
**执行结论**: 你要求的核心问题已完成,且实现了超额目标(`Pyright Error = 0` + 关键改动回归测试通过)。
