背景与目标
本 PR 处理 #520 中仍然有效、且可在仓库内落地的事项:纠正三项 A2A 1.0 协议语义偏差,恢复并固化 conformance 工具链,收敛核心能力文档及 Python 支持边界,并补齐开源贡献入口与运行时可观测性。实现不依赖外部 A2A TCK,也不改动 org/repository 治理或发布权限。
主要变更
A2A 1.0 协议语义
SendMessage/SendStreamingMessage的必需消息字段;空消息分别返回 JSON-RPC-32602和 REST400 INVALID_ARGUMENT-32003、REST400、PUSH_NOTIFICATION_NOT_SUPPORTEDSubscribeToTask在两种 transport 上均返回UnsupportedOperationErrorservice behaviorConformance 与工程卫生
CONFORMANCE_ALLOW_EXTERNAL=1,并注明只能针对专用测试部署运行EventQueue弃用告警/metrics端点;仓库内源码、脚本与模板消息统一使用英文SECURITY.md,避免依赖未必启用的 private vulnerability reporting 页面Issue 关系与范围
a2a-sdk 1.1.3可从 PyPI 获得后再升级,本 PR 不关闭验证
