【根因（main.log 实证）】 19:04 / 19:05 / 19:06 三次会话终止均为同一报错： DeepSeek 400 "Messages with role 'tool' must be a response to a preceding message with 'tool_calls'" 缺陷链：engine 主循环仅在 step.thought 存在（该轮有文本或思考内容）时才 将 assistant 消息加入请求历史。当模型发起纯工具调用（零文本零思考 — DeepSeek 高频行为）时： - assistant(tool_calls) 消息不进 messages - 但 tool 结果消息照常 push → 下一轮请求出现孤立 tool 消息 → 协议 400（不可重试）→ 会话 ERROR 终止 "不稳定" = 模型每轮是否附带文本是概率性行为：带文本正常，纯调用必崩。 DB 持久化侧同源缺陷（if (!step.thought) continue）导致这些步骤的 assistant 与 tool 结果全部不落库 — 重启后工具上下文丢失，模型重复调用。 【修复】 - engine.ts: 有 toolCalls 的轮次必 push assistant（content=null，C-6 规范） - agent.ts: 持久化条件同步修复（无 thought 但有 toolCalls 的步骤落库） - 回归测试: 纯 tool_calls 轮后第二次请求中 tool 消息前必须是带 tool_calls 的 assistant（请求契约断言，engine-toolchain.test.ts） 【纵深防御 — 孤立 tool 消息过滤】 - openai-format.ts（DeepSeek/Agnes/MiMo/OpenAI 四家共享）: 构建请求时 按 tool_call_id 配对过滤孤立 tool 消息（任何来源的历史污染不再 400 死锁） - anthropic.adapter.ts: tool_use/tool_result 同策略配对过滤 - 单测 ×6: 正常配对保留 / 孤立丢弃 / id 不匹配丢弃 / 多轮配对 / includeImages 原位转换 / 非 vision 静默丢弃 【多模态索引对齐收敛】 4 家 adapter 的 images 处理循环原按未过滤的 nonSystemMsgs[i-1] 对齐索引， 孤立 tool 过滤引入后会错位 — 统一收进 buildOpenAICompatibleMessages （includeImages 参数，基于 sanitized 序列原位转换），4 家 adapter 删除 各自的索引对齐循环（DeepSeek vision 判断 / OpenAI 推理模型拒绝保留在 adapter）。 【终止原因可见化】 MAX_ITERATIONS / TIMEOUT 终止此前无任何提示（用户感知"会话直接停止"）— 前端 DONE 事件非 completed 终止原因显示为 system 消息。 【v0.6.1 回归缓解】 web_fetch timeoutMs 120s → 240s：浏览器回退串行化后并发 3 个排队最坏 ~127.5s，旧值让排队末位抓取被工具超时杀掉（表现为抓取不稳定）。 【验证】 lint 0/0；typecheck 双工程 0 错误；test:electron 259/259（+7）； electron-vite build 成功
