Highlights重点内容
Session quality floor restored恢复会话质量底线
The standard and delivery roles return as session quality floors. Delivery sessions now enforce sticky completion gates: strict full verification after writes, plus final readiness checks.标准和交付角色作为会话质量底线回归。交付会话现在强制执行粘性完成门槛：写入后进行严格完整验证，以及最终就绪检查。
Background job lease retention bounded后台任务租约保留有界
Resident background services no longer hold the workspace write lease indefinitely. The lease is released after a 30-second grace period following the final agent run.常驻后台服务不再无限期持有工作区写入租约。在最终代理运行结束后的 30 秒宽限期后，租约将被释放。
Official DeepSeek-V4-Pro persona pinned官方 DeepSeek-V4-Pro 人设固定
Official DeepSeek-V4-Pro now automatically prepends the DeepSeek Harness minimal-mode persona as the first system-prompt paragraph, with reasoning language pinned to English.官方 DeepSeek-V4-Pro 现在自动将 DeepSeek Harness 最小模式人设作为系统提示的第一段前置，并将推理语言固定为英语。
StepFun provider URL canonicalization and preset completion阶跃星辰提供商 URL 规范化与预设补全
StepFun custom OpenAI-compatible endpoints are now canonicalized to prevent 404 errors, and the preset matrix is completed for all channel and protocol combinations.阶跃星辰自定义 OpenAI 兼容端点现已规范化以防止 404 错误，并补全了所有渠道和协议组合的预设矩阵。
