+  `20260907-integrate-design-agent-activity-b7d3f1a8`. Electron Main now
+  normalizes the server's four closed public stages into fixed youth-safe copy;
+  Renderer attaches one transient, update-in-place `AI 处理过程` panel to the exact
+  optimistic user message and collapses completed work without creating a chat Turn
+  or duplicating the right-side Current Specification. Workspace, Direction,
+  operation, pre-command turn sequence, connection generation, cursor, and terminal
+  events keep replay and stale results scoped; unknown outcomes retain the original
+  identity. Integration review additionally preserves prior completed/unknown activity
+  when a later chat starts and keeps each pending user's activity and provisional
+  reply together in visual order. Final committed assistant text continues through
+  the existing provisional assistant bubble and canonical Turn replacement. Focused verification passed 69
+  tests, TypeScript, changed-file ESLint, and all Vite production targets. No server,
+  database, billing, Quote/Task, navigation, package, deployment, publication, or paid
+  Provider call changed.

 AI Design Canvas 现在默认以对话和一张持续可见的“我的创作”卡服务 8-16 岁创作者；专业字段矩阵收进按需打开的“精细调整”，移动端保持对话优先并只挂载一个卡片/底部面板。Creation Card、精细调整、Quote、Task 与结果提示都只投影权威状态，已知问题按 code 转成通俗中文，未知服务端或 Provider 文本不会直接显示。一个 Workspace 仍只公开一个 current Direction、一个 persistent Agent Session 和一个 Current Specification；conversation timeline 只记录交互历史。Chat、direct edits、decision responses、proposal acceptance、locks、Asset binding 与 restore 都通过 `design.input.apply` 进入同一服务端 reducer，Renderer drafts 在 accepted 前保持本地。Main 持有 Works Token、stream ticket、WebSocket、request deadline、stable command/operation IDs 与错误脱敏；unknown result 只能复用原 identity，结构化业务错误不得重放。Generation 由服务端对 exact Specification revision 编译 immutable Quote，客户端只展示 public output plan、warnings、expiry 与 Token Points，并以 Quote ID 调用 `design.generation.confirm`；Provider Prompt、model、route、storage 和 billing atoms 不进入 Renderer。Task/Asset events 独立收敛 Workspace resources，不改写 Living Form。Development 与 packaged builds 均使用 Works Square V2，V1 DTO、local semantic adapter、mutable Quote PATCH 与 editable provider Prompt 已移除。
 
-新提交的 Design chat 会立即从现有 pending operation 投影为带“发送中”或“正在确认”的临时用户气泡，服务端确认的 canonical turn 到达后再替换它；确定失败时原草稿重新出现在输入框。`design.assistant.delta` 只作为内部传输与收敛状态，不显示原始片段，也不在对话区生成独立整理进度栏；右侧 Current Specification 摘要继续承担“AI 当前听懂的内容”。重复连接和事件按 connection generation 与 `chunkIndex` 收敛。
+新提交的 Design chat 会立即从现有 pending operation 投影为带“发送中”或“正在确认”的临时用户气泡，服务端确认的 canonical turn 到达后再替换它；确定失败时原草稿重新出现在输入框。`design.assistant.progress` 经 Main 归一为固定通俗阶段，只在对应用户气泡下形成可更新、可折叠的“AI 处理过程”，不成为对话消息、右侧摘要或模型思考过程。`design.assistant.delta` 仅把已验证并提交的回复临时绘制为同一 operation 的未完成助手气泡，随后由 canonical turn 替换；不生成独立全局整理栏。右侧 Current Specification 摘要继续承担“AI 当前听懂的内容”。重复连接和事件按 connection generation、operation identity 与 `chunkIndex` 收敛。
 
 Canvas 侧栏提供“获取灵感”进入 Prompt Museum。列表、筛选、分页、详情、作者/来源/许可证和图片地址全部由服务端经 Main-owned Host API 提供，客户端不打包静态数据集；服务端相对媒体只允许固定 `/api/image-prompt-museum/{entry}/media/{thumbnail|number}` 形状，并由 Main 注入 Works Bearer、执行一次 401 刷新、可信 raster MIME 与 10 MiB 上限后转为 Renderer data URL；credential-free HTTPS CDN 图片保持直连。图片失败只显示卡片内占位，不阻断卡片或详情；缺少来源 URL 时显示纯文本。“使用此 Prompt”只把原文带回当前 Canvas 输入框，不自动发送。该模块不是投稿、点赞、评论或排行榜社区。客户端契约已就绪，但不据此宣称 Works Square 内容后台和生产数据已经部署。`pnpm run dev` 现在默认使用云端 Canvas 适配器，本地适配器只能通过显式开发命令启用；产品 UI 只保留中文。
