`AgentControlChannel/v1`、`SessionEventEnvelope/v1`、`ActivationLease/v1`、`RuntimeCapabilityMatrix/v1` 与 `Interaction/v1`，通过 schema digest 和 additive-only gate 防止下游再随意改协议。 +- **可靠执行不再强制 PostgreSQL**：AgentKernelStore 支持 InMemory、SQLite 与 PostgreSQL。普通单副本 Agent 可不配置 PG；需要跨 Pod 恢复、接管和高可用时再启用 PostgreSQL，并使用 lease、fencing 与事务 CAS 保证唯一 owner。 +- **Studio 打通本地创作到云端生命周期**：沿用平台既有 `CreateAgent` / `UpdateAgent` 等接口，支持构建、部署、状态、详情、会话、删除、版本选择与二次确认回滚；账号中由 CLI 部署的高代码 Agent 也可直接选择和管理。 +- **前后端会话统一到真实事件流**：Studio 与 Hosted UI 使用 `@kingsoftcloud/ksadk-web@0.3.2`，支持签名 SSE、流式正文、思考、工具、审批、附件、模型、三档审批以及 Goal / Plan 控制；普通前台聊天不依赖 Background 长任务模式。 + +### 新增与变更 + +- Gateway 的 Agent Runtime 路由统一经过 Server admission；Runtime 缺少 Server 签发 permit 时 fail closed。permit 绑定 Agent、session、action、TTL 与 durable nonce，避免伪造引用、会话放大和重放。 +- worker 消费真实 RuntimeEvent 流，统一 run identity、handle digest、lease fencing、冷恢复和 resume；事件日志成为 session 状态的单一事实来源。 +- Studio Agent 编辑支持 prompt、模型、Tool、MCP 与 Skill，并以原子方式回写 manifest；ADK、LangGraph、Codex 等 runtime 共用能力矩阵，不把不支持项伪装成可用。 +- Studio 云端目标采用 AK/SK 在本地服务端完成签名，凭证不进入浏览器；Hermes / OpenClaw 在能力不兼容时提供官方 Dashboard 入口。 +- 构建输出记录 KsADK 版本、来源和 commit id；Operator 对旧制品缺少三元组时保持兼容并标记未知，不阻止旧 Runtime 启动。 +- 评测完成上传、执行、结果与删除闭环；Trace token 区分完整上报、部分上报和未上报，不再把缺失值当作零。 + +### 修复 + +- 修复账号云端目标 `cloud:account:` 被错误截断，导致旧 CLI 高代码 Agent 在下拉列表可见却无法切换的问题。 +- 修复 Studio 云端会话未保留签名流、只在结束时一次性渲染、第二轮复用错误状态、输入框残留以及会话删除不生效的问题。 +- 修复 deployment receipt 覆盖云端权威状态、版本回滚操作互相串扰、详情与版本列表溢出/乱码，以及表单和图标对齐问题。 +- 修复对话创建模型偶发返回非严格 JSON 时无法生成 Agent Draft Patch，并对 provider 原生支持 Responses 但不支持 `web_search` 的场景按工具能力单独协商。 +- 合入社区贡献 PR #53（`pengliang3`）：过滤 LangGraph tool message 中的纯文本工具标记，保留原提交作者信息。 + +### 验证与发布记录 + +- 真实隔离云环境链路覆盖 Studio 构建/部署、旧 CLI Agent 选择、前台多轮流式会话、审批、评测、Trace、版本回滚与删除；测试会话、评测制品、测试 Agent 和 canary namespace 已清理。 +- Web UI：`@kingsoftcloud/ksadk-web@0.3.2`，source `2136448e038b4d8c475fa20e4722252b1ddb2ebc`，GitHub merge
