+# bark-battle 三阶段实施计划：浏览器原型 → AI 创作入口 → 数据库落地
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** 按“三阶段”推进 `bark-battle / 汪汪声浪大作战`：第一阶段先做纯浏览器可运行游戏原型并验证玩法跑通；第二阶段接入 Genarrative 创作入口，用 AI 生成可试玩内容；第三阶段再打通后端数据库、发布、成绩和作品闭环。
+
+**Architecture:** 第一阶段只在前端 runtime 内闭环，优先落 `src/games/bark-battle/` 与直达路由，不依赖后端和 SpacetimeDB。第二阶段在已有创作入口、Agent flow controller、结果页和 runtime shell 上接入 `bark-battle`，AI 只生成配置化草稿，不承接正式业务真相。第三阶段按 `server-rs + Axum + SpacetimeDB` DDD 分层落库，前端只展示后端投影和调用后端 API。
+
+**Tech Stack:** React 19、TypeScript、Vite、Vitest、Testing Library；第一阶段优先 DOM/Canvas 原型，可在验证玩法后再引入 Phaser 3；后端阶段使用 `server-rs`、Axum、SpacetimeDB、shared-contracts。

+
+## 0. 当前上下文 / 假设
+
+- 现有需求与技术文档：
+  - `docs/prd/BARK_BATTLE_BDD_2026-05-11.md`
+  - `docs/technical/BARK_BATTLE_2D_RUNTIME_TECHNICAL_PLAN_2026-05-11.md`
+  - `docs/technical/BARK_BATTLE_BACKEND_DDD_TECHNICAL_PLAN_2026-05-11.md`
+- 用户明确要求阶段顺序：
+  1. 第一阶段：先制作纯浏览器运行的游戏原型，需要测试游戏功能是否能跑通。
+  2. 第二阶段：打通创作入口，使用 AI 赋能游戏内容创作。
+  3. 第三阶段：最后打通数据库落地。
+- 因此本计划调整原技术方案中的落地优先级：
+  - 第一阶段不新增后端表、不接发布、不接作品架。
+  - 第一阶段可以用 mock / local draft 配置与直达路由 `/bark-battle` 完成 playable prototype。
+  - 第一阶段若 Phaser 依赖尚未安装，优先用 React DOM + Canvas/CSS 2D 原型跑通功能；待核心规则验证后再决定是否引入 Phaser，避免第一阶段被依赖安装和素材管线阻塞。
+- 当前仓库 `package.json` 还没有 `phaser` 依赖；如实现者选择 Phaser，需要单独评估依赖引入、包体和测试影响。
+- 本计划只写计划，不直接实现代码。
+
+## 1. 总体分阶段验收口径
+
+### Phase 1：纯浏览器游戏原型
+
+目标：打开本地前端路由即可玩到一局 `bark-battle`，并通过自动测试确认核心规则跑通。
+
+必须满足：
+- 可从 `/bark-battle` 进入独立原型页面。
+- 不登录、不请求后端、不依赖数据库。
+- 支持开发 mock input：点击/按键/按钮可模拟音量峰值；有真实麦克风时可走 Web Audio。
+- 能完成：权限/开始 → 校准或 mock 准备 → 倒计时 → 30 秒 playing → 结算 → 再来一局。
+- 低于阈值输入不计数；有效叫声计数；能量条向玩家或对手移动；结算胜/负/平。
+- 移动端至少能看到能量条、倒计时、双方狗狗、主要按钮和结算。
+
+### Phase 2：AI 创作入口
+
+目标：创作者能从创作中心选择 `bark-battle`，用 AI 生成玩法配置草稿，并进入结果页试玩。
+
+必须满足：
+- 后端入口配置中出现 `bark-battle`，按开关展示/可点击。
+- 前端类型分流、SelectionStage、工作台、结果页、runtime 入口齐全。
+- AI 生成内容仅限配置化草稿：标题、主题、狗狗外观描述、背景风格、难度、局长、AI 对手参数、提示文案 key 等。
+- 生成结果可在本地 runtime 中试玩。
+- 未落库前可先用 session/local state 保存草稿，但要清楚标识为“未发布草稿”。
+
+### Phase 3：数据库落地与正式作品闭环
+
+目标：`bark-battle` 草稿、发布态配置、runtime start/finish、成绩和作品级游玩埋点都进入后端 DDD / SpacetimeDB 链路。
+
+必须满足：
+- `shared-contracts`、`module-bark-battle`、`spacetime-module`、`spacetime-client`、`api-server` 分层清晰。
+- 发布为稳定作品 ID，runtime 从后端读取发布态 config。
+- start 成功写 `work_play_start`：`scope_kind=work`、`scope_id=稳定作品 ID`、metadata 包含 `playType/workId/sourceRoute/userId`。
+- finish 只上传派生指标，不保存原始麦克风音频、波形或可还原语音内容。
+- 作品架/广场/分享/排行榜如启用，均来自后端投影。
+
+---
+
+## 2. Phase 1：纯浏览器运行游戏原型
+
+### Task 1.1：补齐阶段边界文档
+
+**Objective:** 在现有技术方案中明确“先浏览器原型，后 AI 创作，最后数据库”的落地顺序，避免实现时过早接后端。
+
+**Files:**
+- Modify: `docs/technical/BARK_BATTLE_2D_RUNTIME_TECHNICAL_PLAN_2026-05-11.md`
+- Modify: `docs/prd/BARK_BATTLE_BDD_2026-05-11.md`
+
+**Steps:**
+1. 在 runtime 技术方案中新增“三阶段落地顺序”小节。
+2. 明确 Phase 1 不接后端、不接数据库、不接创作入口事实源。
+3. 在 BDD 中补充“浏览器原型 smoke”验收场景。
+4. 运行：
+   ```bash
+   npm run check:encoding -- docs/prd/BARK_BATTLE_BDD_2026-05-11.md docs/technical/BARK_BATTLE_2D_RUNTIME_TECHNICAL_PLAN_2026-05-11.md
+   git diff --check
+   ```
+
+**Expected:** 编码检查和 diff 空白检查通过。
+
+### Task 1.2：建立 Phase 1 目录骨架和类型

+npm run typecheck
+npm run dev:web
+# 手动 smoke: 访问 /bark-battle → 开始 → 模拟叫声 → energy 变化 → 结算 → 再来一局
+```
+
+### Task 1.8：实现 HUD 组件测试

+- 输出归一化 `BarkAudioSample`。
+- 捕获并映射：unsupported、permission-denied、non-secure-context、not-found、not-readable、audio-context-blocked、unknown。
+- stop/restart/page unload 时停止 tracks。
+
+**Validation:**
+```bash
+npm run test -- --run src/games/bark-battle/infrastructure/__tests__/BrowserMicrophoneInput.test.ts src/games/bark-battle/infrastructure/__tests__/AudioAnalyserSampler.test.ts
+npm run typecheck

+- AI 返回结构化草稿。
+- 前端校验并填默认值，不让非法 roundDuration/difficulty 进入 runtime。
+- 错误时保留用户输入和已生成草稿。
+
+**Validation:**
+```bash
+npm run test -- --run src/services/bark-battle-creation/**/*.test.ts
+npm run typecheck

+- 暂不展示发布按钮，或发布按钮显示为后端阶段能力。
+
+**Validation:**
+```bash
+npm run test -- --run src/components/bark-battle-result/BarkBattleResultView.test.tsx
+npm run typecheck
+npm run dev:web
+# 手动 smoke: 创作入口 → AI 草稿 → 结果页 → 试玩 → 返回编辑
+```
+
+### Task 2.6：Phase 2 收口验证
+
+**Commands:**
+```bash
+npm run test -- src/components/platform-entry/platformEntryCreationTypes.test.ts src/components/bark-battle-result/BarkBattleResultView.test.tsx src/services/bark-battle-creation/**/*.test.ts src/games/bark-battle/**/*.test.ts src/games/bark-battle/**/*.test.tsx

+## 6. 风险、取舍与开放问题
+
+### 风险
+
+1. **麦克风权限和移动端 AudioContext 差异大。** 需要 mock input 保底，否则自动化和本地开发会被真实设备阻塞。
+2. **第一阶段过早引入 Phaser 可能拖慢验证。** 当前仓库没有 `phaser` 依赖；建议先用 DOM/Canvas 跑通玩法，再决定是否引入 Phaser。
+3. **AI 草稿和正式发布配置容易漂移。** Phase 2 临时 TS 类型必须在 Phase 3 与 Rust shared-contracts 对齐。
+4. **不能保存原始音频。** 后端阶段只能保存派生指标，任何音频片段、波形、频谱明细都不应落库。
+5. **入口配置事实源在后端/SpacetimeDB。** Phase 2 接入口时不要恢复旧前端静态入口配置。
+
+### 取舍
+
+- Phase 1 先把“游戏是否好玩、功能是否跑通”作为第一目标，不追求正式作品闭环。
+- Phase 2 让 AI 生成内容配置，而不是让 AI 直接生成任意代码或不受控规则。
+- Phase 3 再把正式业务真相交给后端，避免前端 runtime 先背上发布、成绩、排行榜的复杂度。
+
+### 开放问题
+
+1. Phase 1 是否必须使用 Phaser？如果只是验证玩法，可先使用 DOM/CSS/Canvas 原型，后续再替换 renderer。
+2. `bark-battle` 的正式中文名是否固定为“汪汪声浪大作战”？如果名称要改，需先统一文档、入口配置和分享标题。
+3. AI 创作阶段是否需要生成图片/狗狗视觉资产，还是只生成风格描述和使用占位素材？
+4. 是否需要排行榜作为 Phase 3 必选，还是作为数据库落地后的增强项？
+5. 真实麦克风 smoke 需要哪些目标设备：Chrome 桌面、Android Chrome、iOS Safari 是否都纳入首批验收？
+
+---
+
+## 7. 建议执行方式
+
+1. 先按 Phase 1 执行，且每个 domain/application task 坚持 TDD：先失败测试，再实现。
+2. Phase 1 合并前不要接数据库，不要新增后端表，不要把入口配置切到 open。
+3. Phase 1 验证通过后，让产品/团队试玩 `/bark-battle`，确认玩法数值和 UI 方向。
+4. 再进入 Phase 2，把 AI 创作工作台接到同一个 runtime draft config。
+5. 最后进入 Phase 3，按后端 DDD 文档做数据库、发布、成绩和追踪闭环。
