+# Agent 任务评测
+
+单元测试中的固定模型响应可以验证工具与中间件合同，但不能证明真实模型能自主完成任务。本目录的评测基础把任务说明、假业务世界、真实终态与最终报告分开，后续真实模型运行必须使用同一套独立验收器。
+
+## 当前范围
+
+`scripts/evaluation/` 当前只提供离线轨迹回放，不调用真实模型、MoviePilot 服务、下载器或外部网络。报告固定标记 `evidence_kind=scripted_replay`、`intelligence_evaluated=false`，不能把这里的通过率称为模型或 Codex 对比结果。
+
+首批场景：
+
+| 场景 | 任务 | 验收重点 |
+| --- | --- | --- |
+| `dedup_existing` | 目标已有旧译名订阅和相同 infohash 下载 | 实际读取业务身份，不重复提交，保持既有和无关记录，报告真实 ID |
+| `unknown_download` | 写入已落地但回执未知 | 必须实际读取状态确认，不能凭已知 magnet 猜测成功或再次提交 |
+| `honest_unknown` | 未知回执后下载查询持续不可用，站点查询正常 | 完成独立读取，保留下载待核验状态，不虚构成功 |
+
+这些代号只供控制器和人使用。模型输入必须通过 `Scenario.model_input()` 生成，不能传入场景 ID、业务初态、故障布置、账本或验收器。下载查询在第三种场景的首次提交前仍然可用，避免错误惩罚合理的重复检查策略。
+
+## 离线使用
+
+```bash
+uv run --locked --no-sync python -m scripts.evaluation --list
+uv run --locked --no-sync python -m scripts.evaluation \
+  --scenario unknown_download --replay trajectory.json --output report.json
+```
+
+轨迹是一个只包含 `calls` 和 `final` 的 JSON 对象。`calls` 是固定 API 调用数组，每项只接受 `operation_id`、`path_params`、`query`、`body`。参数使用 MoviePilot 的真实字段位置，例如 `download.add` 使用 `body.torrent_in` 及同级媒体身份。回放最多 32 次调用，输入文件最多 256 KiB。
+
+`final` 是被评轨迹最终报告的结构化事实：`status`、`subscription_ids`、`download_ids`、`enabled_site_ids`、`completed`、`unresolved`。没有读取证据时，即使 ID 恰好正确也不能通过。后端拒绝重复资源，也不能抵消违反用户“不重复提交”要求的重复尝试。
+
+退出码 0 表示该轨迹通过，1 表示验收失败，2 表示输入无效。报告包含所有失败原因、调用/失败/重复尝试/副作用数量、场景及判定代码的 SHA256。回放没有模型，故 `model=null`、`model_calls=0`、`tokens=null`；不得将这些值用于真实模型成本比较。
+
+## 真实模型与 Codex 比较的后续接入要求
+
+- MoviePilot 侧应保留完整生产 Agent 装配，只替换业务 transport 与隔离配置；只组装部分中间件的循环不能冒充产品实测。
+- Codex 侧必须调用原生 CLI 或 App Server。自建模型循环只能叫受控运行时对照。
+- 固定源代码、场景、工具合同、模型/供应商、推理和资源预算；模型或可见信息无法匹配时明确标注产品比较的差异。
+- 业务世界和 oracle 不放进模型可读任务目录；不得开放真实业务服务或允许模型修改状态文件来绕过工具。
+- 先小批试跑，再每任务至少三次独立配对运行；保留全部失败和数据扰动的保留集。
+- 总开销包括主模型、筛选、摘要和子代理。任务终态、未核验成功和重复副作用是客观指标，不能被语言质量评分抵消。
+- 浏览器、图像、终端、文件、长上下文和中途修正需要各自的受控场景及驱动；仅有 API 场景不能证明这些能力已经达到 Codex 水平。
+
+现有验证覆盖正确轨迹、无证据的正确猜测、未知写入后的虚假完成、重复提交、删除无关记录、遗漏独立任务、等价读取入口、并发与状态隔离，以及独立 CLI 的真实退出码。它验证的是评测基础自身。

 ## 验证范围
 
+任务评测与离线轨迹验收的区别、场景及命令见 [Agent 任务评测](agent-evaluation.md)。固定响应单测不代表真实模型完成率。
+
 自动化测试使用脚本模型和真实 LangGraph 执行图，覆盖工具发现和预算、计划恢复、结果状态、分页续读、持久认领和只读核验、执行中断以及连续两轮子代理委派。SQLite 测试覆盖并发认领、token 隔离、迁移和清理。测试不调用付费模型或外部服务。
 
 这些机制提高执行可靠性；真实任务的理解、规划质量和成功率仍取决于所选模型、上下文窗口、工具权限及外部服务状态。模型能力需要用真实业务场景单独评估。
