- 新表 agent_action(name/app/aliases/params/steps/preconditions/hits/时间)，
独立于人工维护的 custom_action(2B 决策)：AI 自学动作不污染手建动作
- 沉淀：任务成功后从**成功**工具轨迹(_ACTION_TOOLS: open_app/tap_text/tap_element/
type_text/clipboard/swipe/press_key/wake/sleep)用模型蒸馏为命名动作；steps 用
编辑器 schema，**必须元素定位**(xpath/text/resourceId/description…)，
**显式剔除 click_xy 等坐标类**；on_tool 记录带 result 的结构化轨迹以判成败
- 兼容模型形状漂移：顶层 {action,params} 自动归一为 {name,steps}；宽容 JSON 解析
(围栏/尾逗号/中文引号/坏对象逐条抢救)，实测模型常返回带语法错误的 JSON
- 召回：执行前按动作名/别名命中(或相似度≥0.34)取 top3，注入 system prompt
「可复用动作」段(含元素定位)，模型可跳过重新探索；hits 回写
- 文档同步：ARCHITECTURE §3.6(agent_action 表)、API.md(🧠 动作经验 伪卡片 + 动作库
说明)、AI_TASK_GEN P1(沉淀进展)
实测：跑「打开抖音，点搜索」→ 沉淀「打开抖音」；下一轮同指令命中并注入；日志
「命中可复用动作 1 个」「动作提炼: 轨迹 5 步, 成功可沉淀 1 步」「动作经验已保存 1 条」
