- 协议与 C# 版 card-printer-agent 逐字段对齐（38200-38202 顺延、CORS *、串行任务队列、30 分钟保留） - macOS CUPS 后端：lpoptions 队列发现 + lp 参数列表提交（LC_ALL=C 防本地化粘连坑） - --mock 模拟模式 + bin/agent.dart headless 入口 + 测试卡生成工具 - 真机验收：HiTi CS-200e status 就绪 + 真实出卡；macOS 通用二进制构建通过 - App Sandbox 已关闭（服务需绑回环端口并调用 lp 子进程）；zaxprint URL scheme 已注册
