Summary

系统性清理综合评审（3.78/5）识别的 5 项技术债：ReActEngine 流式/非流式 ~800 行重复、TeamOrchestrator 2080 行上帝类、except Exception 345+ 处滥用（关键路径降级静默通过）、Any 类型残留（bitable/ 等）、前端 chat.ts 2025 行巨型文件。重构在 5989 单测+35 新增 vitest 保障下完成，无新回归，关键路径测试全过。

What Changed

Unit	模块	变更	收益
U1	`core/react.py`	`_execute_loop` 改为 async generator，`execute`/`execute_stream` 共用骨架	消除 ~800 行重复，行为等价有 golden trajectory 快照锁定
U2	`experts/orchestrator.py` + 7 个 mixin	2080 行上帝类拆为 `PhaseExecutor`/`DebateRunner`/`ReviewGate`/`DivergenceDetector`/`RollbackHandler`/`Synthesizer`/`InterventionHandler`	主类 1576→~440 行，单方法 ≤100 行
U3	`core/`+`experts/` except 治理	关键路径 `except Exception` 分类收窄，新增 `ReviewResult` dataclass 替代裸 tuple + `[DEGRADED]` 字符串前缀	验收降级可编程判断，`review_result` WS 事件携带 `degraded` 字段
U4	`bitable/`+`pipeline_state.py`+`tools/computer_use_session.py`	`Any` → `TypeAlias`(`BitableRecord`/`FormulaResult`/`SessionState`) + `object` + `TYPE_CHECKING` Protocol	消除 40 处 `Any`，恢复类型契约
U5	`server/frontend/src/stores/chat*.ts`	2025 行 chat.ts 拆为 `chatStore`(498)/`chatSocket`(165)/`chatStream`(1557) + 35 新增 vitest	`dispatchWsEvent` 纯函数覆盖 30+ WS 事件类型，可独立测试

Key Design Decisions

U1 async generator 统一骨架（KTD1）：_execute_loop 始终 yield ReActEvent，execute 收集所有事件提取 ReActResult，execute_stream 直接 async for 透传。无需 callback/queue 桥接，最简。新增 'final_result' event_type 字符串值携带 ReActResult，不新建枚举。
U2 Mixin 而非组合（KTD2）：37 个方法大量访问 self._experts/self._workspace/self._broadcast_event 共享状态，Mixin 保持 self 访问最小改动。每个 mixin 文件顶部注明 # TYPE_CHECKING: 由 TeamOrchestrator 组合。
U3 结构化降级（KTD3）：ReviewResult(passed, degraded, feedback) 替代 (bool, str) tuple + [DEGRADED] 字符串前缀。_review_phase_output 的 except 收窄为 (LLMProviderError, asyncio.TimeoutError, ConnectionError, RuntimeError)，降级返回 passed=True, degraded=True。_phase_executor 广播 review_result 事件时携带 degraded 字段。
U4 object + Protocol 模式（KTD4）：循环依赖场景用 object（最严格"任意类型"，禁止属性访问）+ TYPE_CHECKING 块定义 Protocol（_RedisLike/_RecalcWorker）。可直接导入的类型用 TypeAlias。
U5 按职责层拆分（KTD5）：chatSocket（连接/心跳/重连）、chatStream（dispatchWsEvent 纯函数 + 30+ 事件分发）、chatStore（Pinia store 组合 composables）。chatStore 保留向后兼容 export 别名。

Test Plan

新增测试：

tests/unit/test_react_golden_trajectory.py (617 行) — U1 golden trajectory 快照，锁定 execute/execute_stream 行为等价
tests/unit/server/frontend/tests/unit/stores/chatStream.test.ts (563 行, 19 tests) — U5 dispatchWsEvent 全事件类型覆盖
tests/unit/server/frontend/tests/unit/stores/chatSocket.test.ts (255 行, 13 tests) — U5 useChatSocket composable + resolveIncomingConvId

回归验证（与 main 基线对比）：

core+experts+evolution+memory: 894 全过
react+team_orchestrator+golden: 190 全过
bitable+computer_use+pipeline+orchestrator: 202 过 116 skip
auth+admin+chat+cli+mcp+quality+router+skills: 1025 过 / 2 基线失败 (router test_intent)
server: 215 过 / 110 失败 — 与 main 基线完全一致 (110 失败，无新回归)
ruff: 67 errors (基线 77，净减 10)
frontend typecheck: 通过
frontend vitest: 68/69 (1 基线失败 tauri-auth localStorage 状态泄漏)

环境约束：Python 3.14 + litellm 缺失，跳过 test_cache.py。

Post-Deploy Monitoring & Validation

Log queries:

review_result WS 事件中 degraded: true 计数 — 验收降级频率监控
phase_violation 事件计数 — phase 策略执行情况
ReActEngine final_result event status 分布 (success/timeout/cancelled/empty_fallback)

Metrics:

TeamOrchestrator 阶段执行耗时 (phase_started → phase_completed)
ReActEngine 步数分布 (max_steps 达到频率)
chatSocket 重连频率 (WebSocket disconnect 事件)

Healthy signals:

degraded: true 比例 < 5% (LLM 验收正常)
final_result.status=success 比例 > 80%
阶段失败率 < 10%

Failure signals:

degraded: true 比例突增 → LLM gateway 可用性问题
final_result.status=empty_fallback 突增 → LLM 调用失败
chatSocket 重连频率突增 → WebSocket 稳定性问题

Rollback trigger: 任一指标超过阈值 2 倍持续 15 分钟 → 回滚到 main (0962df1)

Validation window: 合并后 24h，owner: @chiguyong

Known Residuals

chatStream.ts 1557 行 vs plan 估计 ~300 行（30+ WS 事件类型决定，plan Verification 只要求 chatStore ≤500，已满足）
U3 plan 要求的"验收 LLM 超时"独立测试未单独新增（现有 test_synthesize_without_llm_concatenates 间接覆盖 RuntimeError 降级路径）
server/routes/ 的 except Exception 整治（portal.py 19、chat.py 16）deferred to follow-up PR
llm//memory//client/ 的 Any 残留治理 deferred to follow-up PR
bitable/ 内部 Any 残留（repository.py 5、recalc_worker.py 2、ingestion/* 3，共 10 处）deferred to follow-up PR

- chat.py: accurate ExecutionMode log message

03b1e3d751 docs: add systematic tech debt cleanup plan (U1-U5)

e61f98898f refactor(core): unify ReActEngine execute/execute_stream via async generator (U1)

- Convert _execute_loop to async generator yielding ReActEvent; both execute and execute_stream delegate to it, eliminating ~760 lines of duplicated loop logic (execute_stream 813 -> 53 lines).

- Add 'final_result' event_type carrying ReActResult; execute extracts result from final event, execute_stream forwards events (backward-compatible 'final_answer' retained).

- Unify _drain_phase_violations across both paths.

- Add 14 golden-trajectory characterization tests.

- Fix test_execute_stream_with_compressor mock gateway (chat_stream test-infra gap). 130 react tests pass, 762 core+experts pass, no regressions.

47ee2449df refactor(experts): split TeamOrchestrator god class into 7 mixins (U2)

- Split 2085-line orchestrator.py into main class (592 lines) + 7 responsibility-focused mixins: PhaseExecutor, DebateRunner, ReviewGate, DivergenceDetector, RollbackHandler, Synthesizer, InterventionHandler.

- Mixin pattern preserves self access to shared state (_experts/_workspace/_broadcast_event); method bodies moved verbatim to minimize regression risk. Each mixin declares TYPE_CHECKING Protocol for shared state.

- Split _execute_execution_phase (~290 lines) into _prepare_phase_context/_run_agent_steps/_finalize_phase (each <=100 lines).

- All mixins <=400 lines, main class <=600 lines. [DEGRADED] prefix annotations preserved in ReviewGateMixin.

- 60 team_orchestrator tests pass (behavior unchanged), 469 experts tests pass, ruff clean.

be5c4e09f8 refactor(core,experts): classify except Exception + structured ReviewResult (U3)

ReviewResult dataclass (passed/degraded/feedback) replaces tuple+[DEGRADED] prefix in _review_phase_output; 3 review_result WS payloads now carry degraded field (AE3).

except Exception narrowed to specific types across 10 files (core/react, rewoo, base, orchestrator, dispatcher, plan_exec_engine + experts/orchestrator, _phase_executor, _review_gate + orchestrator/pipeline_engine). Baseline 140 -> 66 occurrences (>=50% reduction).

Fix RuntimeError regression: review-gate + compression paths now catch RuntimeError (LLM/provider internal errors) to preserve degradation semantics. Test side_effect switched to functional form to avoid StopIteration on list exhaustion.

ruff clean; 135 key + 469 experts + 163 core tests pass.

1033346913 refactor(bitable,tools): replace Any with concrete types + Protocol (U4)

BitableRecord/FormulaResult/SessionState TypeAlias replace dict[str, Any]; _redis/_engine/_session_factory typed as object | None with TYPE_CHECKING Protocol (_RedisLike, _RecalcWorker); Coroutine[Any, Any, Any] retained as legitimate type param.

Baseline 40 : Any occurrences -> 0 across 6 in-scope files (target <=5). Deferred: repository.py/recalc_worker.py/ingestion/* (10 occurrences, separate PR).

ruff clean; 367 passed + 116 skipped (bitable + pipeline_state + tools).

ec9a0a1f70 refactor(frontend): split chat.ts (2025 lines) into chatStore/chatSocket/chatStream (U5)

chatStore.ts (498 lines, <=500 target met): Pinia store entry composing useChatSocket + useChatStream; retains all actions + backward-compat export aliases.

chatSocket.ts (165 lines): resolveIncomingConvId pure fn + useChatSocket composable (connect/disconnect/heartbeat/reconnect).

chatStream.ts (1557 lines): dispatchWsEvent pure fn for 30+ WS event types + useChatStream composable. Exceeds plan ~300 estimate due to discriminated union breadth (each case 30-50 lines); core testability goal met.

8 components + chat-phase.test.ts migrated from @/stores/chat to @/stores/chatStore.

vitest: 35 new tests (chatStream 19 + chatSocket 13 + chat-phase 3) all green; typecheck passes.
