#!/usr/bin/env bash
# 技能治理定时任务入口（由 launchd 调用，见 scripts/install-schedulers.sh）
#
# 设计原则：脚本只做「确定性」的事——跑门禁、扫漂移、生成清单。
# 需要模型判断的部分（真跑 evals、人工审阅 routing）不在脚本里做，只生成 queue 文件，
# 由项目经理 Bot 在 7:30 项目日报里接手执行。这样节拍不依赖任何会话的记忆。
#
# 用法:
#   ./scripts/scheduled-task.sh daily     # 每天 07:20，先于 7:30 项目日报
#   ./scripts/scheduled-task.sh weekly    # 每周一 10:00
#   ./scripts/scheduled-task.sh monthly   # 每月 1 日 10:00（1/4/7/10 月附带季度清单）
