 # xc_validation_strategy_gguf
 
-GGUF 模型下载 + 验证任务提交流水线策略服务：批量创建 GGUF 模型下载任务（最大并发 8），
-每个模型下载成功后立即提交 hygon / bi150 两个验证任务，之后保持 HTTP 服务存活供平台探活。
+本版本为纯下载策略：使用 `zhoushasha` 账号批量创建 `main.py` 中未注释的 GGUF 模型下载任务（最大并发 8），不提交验证任务；之后保持 HTTP 服务存活供平台探活。
 
 ## 功能
 
-- 自动登录 ModelHub 获取 Token（失败时回退到预设 Token）
+- 启动时登录 ModelHub 获取新 Token，并检查账号身份及有效期；登录失败时停止，不回退到过期 Token
 - 按流水线批量创建 GGUF 模型下载任务（HuggingFace 源，最大并发 8）
-- 每个模型下载成功后，立即提交 hygon_k100-ai 与 Iluvatar_bi-150 两个验证任务（llamacpp 框架）
+- 当前 `DOWNLOAD_ONLY=True`，不调用验证任务提交接口；验证任务由其他策略负责
 - 下载成功的模型 ID 写入 `downloaded_success_models.txt`
 - 暴露 `/health` 和 `/status` 接口满足平台运行时契约
