+# 敲木鱼音频延迟上传与本地标准化测试用例
+
+## 覆盖目标
+
+- 选择上传或录音结束后只在浏览器本地处理，不请求 OSS 上传凭证。
+- 用户点击 `生成` 时才上传处理后的音频 Blob/File，并把确认后的 `WoodenFishAudioAsset` 放入创建 session payload。
+- 上传和录音统一执行前后声音过小片段裁切、最长 1 秒限制、近似 `-15 LKFS` 响度平衡和峰值保护。
+- 音频面板明确显示 `最长 1 秒`，并正确处理上传、录音、重置、禁用和错误状态。
+- OSS 上传 client 只接收 Blob/File，不接受 Data URL，并覆盖上传凭证、OSS POST、资产确认和错误分支。
+
+## 音频处理 helper
+
+- 空文件：`size=0`，报 `音频文件为空，请重新选择。`
+- 非音频 MIME：`text/plain`，报 `请选择音频文件。`
+- 浏览器没有 `AudioContext`：报 `当前浏览器不支持音频处理。`
+- `decodeAudioData` 失败：报 `音频解码失败，请重新选择。`
+- 全静音或声音全低于阈值：报 `音频声音过小，请重新录制或上传。`
+- 前后静音裁切：低于阈值的头尾帧被裁掉，`startFrame` 和 `frameCount` 正确。
+- 裁切后刚好 `1000ms`：允许通过。
+- 裁切后超过 `1000ms`：报 `音频最长 1 秒。`
+- 上传来源 `uploaded` 与录音来源 `recorded`：返回 pending asset 保留对应 source。
+- 原文件名有扩展名：输出 `.wav` 文件名；无扩展名补 `.wav`；空白文件名输出 `creative-audio.wav`。
+- `URL.createObjectURL` 存在：`audioSrc` / `previewUrl` 为 blob URL；不存在时返回空字符串且不阻断处理。
+- 近似响度平衡：低 RMS 样本被拉向 `-15 LKFS` 目标。
+- 峰值保护：高峰值样本增益后不超过 `peakCeiling`。
+- 零能量 section：归一化阶段报声音过小。
+- WAV 编码：写入 RIFF/WAVE/data header、PCM16 数据长度和采样值。
+
+## 音频输入面板
+
+- 传入 `limitLabel` 时显示 `最长 1 秒`；未传入时不显示限制标签。
+- 无资产时显示默认音效文案。
+- 有资产且 `audioSrc` 存在时渲染 `<audio controls>`。
+- 有资产但无 `audioSrc` 时显示 `音效已选择`。
+- 点击重置调用 `onAssetChange(null)`。
+- 上传取消选择时不读取音频、不写入资产。
+- 上传成功后调用 `readFileAsAsset(file, 'uploaded')`，清空错误并写入资产。
+- 上传失败时展示错误，不写入资产。
+- 浏览器不支持录音时提示 `当前浏览器不支持录音。`
+- 麦克风启动失败时透传启动错误。
+- 录音停止后把 Blob 包成 File，并以 `recorded` 来源读取。
+- 录音保存失败时展示错误。
+- disabled 状态不启动录音，文件输入禁用。
+
+## 木鱼工作台链路
+
+- 音频面板显示 `最长 1 秒`，并只保留上传和录音入口。
+- 选择上传音频后只调用本地处理 helper，不调用 `uploadWoodenFishHitSoundAsset`。
+- 点击 `生成` 且有 pending 音频时，先上传处理后的 WAV，再调用 `woodenFishClient.createSession`。
+- 上传给 OSS 的文件是处理后的 WAV，文件名和 MIME 为 `.wav` / `audio/wav`。
+- 提交 payload 使用 OSS confirmed asset，不包含 `data:audio`。
+- 未选择音频时不上传 OSS，payload 使用默认木鱼音。
+- 处理阶段报超过 1 秒时展示错误，不写入用户音频；继续生成时走默认木鱼音。
+- OSS 上传失败时停留工作台，展示错误，不创建 session。
+- `createSession` 失败时停留工作台，展示错误。
+- 提交中重复点击 `生成` 不重复上传、不重复创建 session。
+- 替换本地音频时回收旧 `previewUrl`。
+
+## 木鱼音频上传 client
+
+- 空 Blob/File、超过 20MB、非音频 MIME 均在本地拒绝，不创建上传凭证。
+- File 上传默认使用 `file.name` 和 `file.type`。
+- Blob 上传支持通过显式文件名扩展推断 `audio/wav` 等音频 MIME。
+- Blob 缺少 MIME 且扩展未知时拒绝上传。
+- direct upload ticket 请求包含 `legacyPrefix`、path segments、fileName、contentType、access、maxSizeBytes 和木鱼音频 metadata。
+- OSS POST 成功后调用 `/api/assets/objects/confirm`。
+- OSS POST 非 2xx 时提示 `上传敲击音效失败。`，不确认资产对象。
+- confirm 失败时透传确认错误。
+- confirm 请求包含 bucket、objectKey、contentType、contentLength、assetKind、accessPolicy 和 entityId。
+- 成功返回的 `WoodenFishAudioAsset` 包含 assetObjectId、audioObjectKey、audioSrc、source 和 prompt。

 - 外部 API 失败审计：外部供应商调用未成功时，`api-server` 必须发送 OTLP 失败事件并写入 `tracking_event`。VectorEngine 图片 provider 在 `platform-image` 内输出结构化日志和 `PlatformImageFailureAudit`，覆盖 `request_send`、`response_body`、`upstream_status`、`response_parse`、`missing_image` 和 `image_download` 阶段；`api-server` 只把该 audit 映射成 `external_api_call_failure`，`scope_kind = module`、`scope_id = provider`、`module_key = external-api`。metadata 固定包含 provider、endpoint、operation、failureStage、statusCode、statusClass、timeout、retryable、errorMessage、latencyMs、promptChars、referenceImageCount、imageModel、rawExcerpt，以及在调用方可获得上下文时补充的 `userId`（触发者）和 `profileId`（草稿 / 作品 / 场景作用域）。图片生成入口应优先把 owner user id 和 profile id 透传到失败审计，不要只保留 provider 级聚合，否则很难按“谁触发、哪个作品触发”定位问题。入库优先复用 tracking outbox，outbox 不可写或保护阈值拒绝时回退同步写 SpacetimeDB；不得新增前端兜底或在 SpacetimeDB reducer 内做外部 I/O。
 - 外部生成运行记录：所有外部生成编排的完成态统一写入 `tracking_event`，`event_key = external_generation_run`，`scope_kind = module`，`scope_id = provider`，`module_key = external-generation`。metadata 固定包含 `runId`、`provider`、`operation`、`requestLabel`、`requestPayload`、`status`、`success`、`failureReason`、`providerRequestId`、`resultPayload`、`startedAtMicros`、`completedAtMicros` 和 `durationMs`。这类记录只用于运行审计和排障，不再走 `ai_task` 旧表。

 3. `功德有什么`：最多 8 条飘字，创作态首屏只保留一个默认词条 `幸运`，其下提供加号格继续追加词条；创作态只保存词条名，运行态飘字展示时再追加 `+1`。运行态顶部总数卡采用品牌化徽标样式，子项计数器预置展示在可展开面板中，未出现词条初始值为 0。
