"""铸渊全自动蒸馏流水线 v2.0

D100教训修复：
  教训1：写了脚本没启动 = 白写 → 启动时检测所有状态，已有完成的跳过
  教训2：只有一条检测路径 → 三重检测：本地文件 + COS路径 + 进度标记
  教训3：轮询间隔300秒太久 → 改为60秒

流程：
  Phase 0: 等待代码模型完成（轮询COS和本地）
  Phase 1: 母模型(7B) → 蒸馏 → 霜砚1.5B
  Phase 2: 霜砚语料 → 深度SFT霜砚1.5B
  Phase 3: 代码模型(7B) → 蒸馏 → 铸渊1.5B
  Phase 4: 铸渊语料 → 深度SFT铸渊1.5B
  Phase 5: 全部上传COS

使用方法：
  export ZY_OSS_KEY=... ZY_OSS_SECRET=...
  nohup python3 -u scripts/auto_distill_pipeline.py > distill_pipeline.log 2>&1 &
