原始思想与改编边界
让动作与基于观察的决策交替推进。推理仅记录模型实际提供的内容，不编造隐藏思维。 原始来源。框架与用户的分工
ResearchState 保留有限的近期观察；prepare 提供任务与证据，reduce 接收实际 ToolResult。每次请求和动作仍由 Engine 执行。 QitOS 已提供：模型事务与 usage、工具权限/校验、Env 执行、Session、ArtifactRef 和 Trajectory。用户编写：任务、策略、完成检查及记忆/技能选择。本轮补齐：自定义 agent_factory 接入、持久技能版本、完整正文加载、显式 Memdir 删除与产物引用的数据权限修正。 核心增量位于完整源码中的 agent.py；CLI 负责显式配置与资源生命周期，evaluate.py 是控制端检查器。任务由项目自有合成材料组成，不是论文基准或真实客户数据。安装、配置与运行
先按仓库构建说明安装本轮 QitOS wheel（当前 PyPI 版本不能替代未发布实现），再安装本课程。真实地址与凭据仅放在仓库外。模型配置采用完整 qitos.agent 文件，课程只读取其中 model；不是通过环境变量注入 key。 每次 run 使用新的仓库外目录；resume 只接受同一项目重构的工厂与 resolver。 默认输出上限 10,240，可通过私有模型配置提高；单任务步数、请求数和运行时间读取公开配置。validate 不调用模型，真实执行必须显式 —live。Docker 不可用时不能降级到宿主。模型失败、未完成任务和人工干预均保留，不能自动改为通过。验证、练习与组合
独立检查器核验资料/数值或实际代码结果，不接受模型自报成功。计划修订、技能实际加载、子 Session 身份与失败也须单独验收。Session 恢复不是文件回滚；生成代码只在受限 Env 内执行。 练习：替换证据排序策略，保持数值与来源检查器不变。 组合：与 PlanAct 运行同样任务，对比真实请求数、纠错行为和独立结果。 完整矩阵：三种任务各三轮。ReAct/PlanAct 使用同样任务；PlanAct 的 static、Hermes 的 no-memory、Voyager 的 no-skills 是明确对照，不以一次成功作性能结论。私有原始轨迹不能直接公开；仅在检查许可与脱敏后发布衍生摘要。python -m pip install .
