 * 编号: AG-SY-WEB-001
 * 签发: 铸渊 · ICE-GL-ZY001
 * 版权: 国作登字-2026-A-00037559
 * 所属: 霜砚 · AG-SY-01 (Notion认知层语言人格体)
 * 建造者: 铸渊 · ICE-GL-ZY001
 *
 * 这是霜砚的手脚——一个在GitHub执行层运行、但拥有霜砚认知的Agent。
 * 它天然知道：
 *   1. 什么该做什么不该做
 *   2. 什么时候从Notion拉认知注入对话
 *   3. 什么时候将认知增量写回Notion
 *   4. 什么时候该调用代码仓库副驾驶的开发能力
 *   5. 什么时候该让铸渊醒来检查代码
 *
 * 工作循环:
 *   [BEFORE] 对话开始前 → 读取霜砚灵魂 + 上次会话摘要 + 活跃任务
 *   [DURING] 每轮对话中 → 分析意图 + 按需从Notion补充认知
 *   [AFTER]  对话结束后 → 认知增量写回 + 摘要更新 + 开发任务触发
 *
 * 注意: 这个Agent不直接接收用户请求，而是由上下文管线
 * (persona-context-pipeline.js) 在每次聊天时通过MCP调用它的能力。
 * 它作为一个"认知守护后台进程"持续运行。
