+4. B3 对外仍返回当前首版快照字段 `snapshotVersion / clientSnapshotVersion` 对应语义；`module-match3d` 内部的 `board_version` 只在适配层中转换，避免影响并行中的 B4/F3 接入。

+# 抓大鹅 Match3D F1 创作入口与 Agent UI 落地记录 2026-04-30
+
+## 1. 阶段边界
+
+本文件承接《MATCH3D_CREATION_AND_RUNTIME_MINIMAL_IMPLEMENTATION_2026-04-30.md》的 F1 包。
+
+F1 只处理前端创作入口、Agent 工作区和等待后端 B5 facade 前的 mock client。它不实现运行态规则，不修改 SpacetimeDB 表，不接 `api-server` 路由。
+
+## 2. 本阶段写入范围
+
+1. `src/components/platform-entry/`
+2. `src/components/match3d-creation/`
+3. `src/services/match3d-creation/`
+4. `packages/shared/src/contracts/match3dAgent.ts`
+
+其中 `packages/shared/src/contracts/match3dAgent.ts` 作为 F1 与后续 B5 的 DTO 对齐点，F1 mock client 不自建脱离共享契约的临时类型。
+
+## 3. 入口接入
+
+平台入口新增可见创作类型：
+
+```text
+id: match3d
+title: 抓大鹅
+subtitle: 经典消除玩法
+badge: 可创建
+```
+
+入口来源统一走 `getVisiblePlatformCreationTypes()`，因此创作首页首屏卡带与“选择创作类型”弹层会同时出现抓大鹅。
+
+## 4. Agent 工作区
+
+新增 `Match3DAgentWorkspace`，复用通用 `CreationAgentWorkspace`。
+
+Agent 只收集三类锚点：
+
+1. 题材主题。
+2. 需要消除次数。
+3. 难度。
+
+工作区支持参考图片上传入口。图片在 F1 中先以 Data URL 形式随消息 payload 带给 mock client；B5 接入后由后端 facade 替换为正式资产上传与引用。
+
+UI 中不默认展示玩法规则长文，只展示进度、锚点、聊天内容和必要按钮。
+
+## 5. mock client
+
+新增 `src/services/match3d-creation/match3dCreationClient.ts`。
+
+mock client 提供：
+
+1. `createMatch3DCreationSession`
+2. `getMatch3DCreationSession`
+3. `streamMatch3DCreationMessage`
+4. `executeMatch3DCreationAction`
+
+mock 行为：
+
+1. 创建本地会话。
+2. 从中文输入中提取题材、消除次数和难度。
+3. 支持“自动配置”。
+4. 当三项配置完整时允许执行 `match3d_compile_draft`。
+5. 编译后返回 `draft_ready` 会话和草稿。
+
+## 6. 结果承接
+
+F1 新增 `Match3DDraftReadyView` 作为草稿生成后的临时承接页，只展示草稿基础信息并允许返回 Agent 修改。
+
+正式结果页的基础信息编辑、封面图、试玩、发布由 F2 接入，F1 不在这里模拟发布。
+
+## 7. 后续替换点
+
+B5 完成后，只需要把 `match3dCreationClient` 的本地 Map mock 替换为 HTTP/SSE facade：
+
+```text
+POST /api/creation/match3d/sessions
+GET  /api/creation/match3d/sessions/:sessionId
+POST /api/creation/match3d/sessions/:sessionId/messages/stream
+POST /api/creation/match3d/sessions/:sessionId/compile
+```
+
+`PlatformEntryFlowShellImpl` 与 `Match3DAgentWorkspace` 不应再改一轮业务字段。
+
+## 8. 验收口径
+
+1. 创作首页能看到“抓大鹅 / 经典消除玩法”。
+2. 弹层选择“抓大鹅”能进入 Agent 工作区。
+3. 输入题材、消除次数、难度后进度到 `100%`。
+4. 点击“生成结果页”进入草稿承接页。
+5. 可从草稿承接页返回 Agent 修改。
+6. `npm run check:encoding` 通过。
+7. `npm run typecheck` 通过。
