MUSE 品牌数字人 Demo 更新到最新代码，仍放在 examples/dam/brand-digital-human-studio/workbench/。独立本机入口支持页面配置模型服务并手动提交；仓库目录入口只展示模拟流程，不提供密钥输入或真实生成。

本轮新增和更新：

• Seedance 页面地址配置、万相官方/兼容视频网关协议、自定义 Base URL 与模型别名。
• 原任务结果恢复，区分明确渠道拒绝与待核对提交，避免自动重复收费生成。
• 成品、任务与资产首页最近作品使用结果视频帧；长错误显示摘要及换行详情。
• 全身表演与帽子展示案例预设，只填草稿，不自动提交模型。
• 保留演示登录、素材调用、声音复刻/TTS/口型适配、模拟任务及审核复用；正式共享、RBAC与客户模型质量尚未验收。

隐私及范围：只同步代码和抽象说明。没有上传 API Key、客户素材或录音、真实生成视频、签名结果 URL、报价文件及运行数据。.env.example 密钥为空，真实调用默认关闭；运行目录被忽略。沿用已有合成图与固定示意 MP4，案例外102个文件和原示例媒体字节保持一致；本轮提交只涉及 MUSE 案例目录。

验证：

• 原目录依赖锁文件被运行进程占用时，改用隔离同源码安装；隔离 npm ci 成功。恢复原目录依赖后，两目录 npm run check 均通过，包括 MUSE 68项接口测试及原案例领域/POC检查。
• MUSE 6项、Persona 原有8项浏览器回归通过。
• 桌面1440×1000、手机390×844检查预设、长错误与模拟入口，无页面/控制台异常、目录 API 与外部请求为0。
• 独立页面用模拟配置及已有示意 MP4 检查网关表单和视频帧封面，无实际模型调用。

状态保持 prototype，外部适配不标成已验收；人物一致性、声线口型、全身表演和帽子细节仍需客户授权素材与真实账号验证。

Reviewed the full diff (82 files, +19,810/-36) and ran the repo check locally on Node 22.22.2. Verdict: approve — the case is well-scoped, honest about its limits, and safe to publish.

What I verified

• Catalog/domain consistency: catalog/cases.json gains the brand-digital-human-studio entry with status: "prototype", path and domain dam matching catalog/domains.json; root README.md count updated to two cases. case.json capabilities correctly keep every external adapter at mode: "unavailable" — nothing is marked connected/verified.
• No credentials or machine leakage: full-diff scan for keys/Bearer tokens/AKID/LTAI/sk- patterns and absolute local paths returns nothing. .env.example holds empty placeholders only; every *_ENABLE_REAL switch defaults to false.
• Public-demo isolation is real: scripts/serve.mjs (the 4173 catalog route) only adds an .mp4 media type; the proxy lives behind its own server/index.mjs entry on 4318/8788, guards Host to loopback, requires the x-studio-client header and a same-origin Origin for non-GET calls, and rejects private/loopback media URLs via the DNS check in publicUrl. The catalog entry therefore cannot reach a paid API.
• CI: both check runs pass on the PR head.
• Mergeability: MERGEABLE / clean, not a fork, not behind main, no prior reviews to collide with.

Non-blocking notes (no change requested for this merge)

1. server/seedance.test.mjs (and the same settle() helper pattern in wan.test.mjs) has a tight timing budget: the helper polls state.json for 100 × 5 ms (≈500 ms) waiting for providerStatus !== "submitting", but the submit handler's background block must first await the gateway round-trip and an fs save(). On a slow Windows host this deterministic race makes the helper throw Fixture submission did not finish. Reproduced locally: 12/68 seedance and 10/68 wan subtests fail on Windows while the actual request path afterwards returns status: "completed" correctly — it is a harness latency issue, not a product defect. Raising the loop bound (or asserting on a promise instead of polling the file) would make the suite portable; CI on ubuntu-latest is unaffected.
2. The MUSE e2e config hardcodes the catalog server to port 4179; fine for CI but worth a comment so a future second case does not silently collide on the same fixed port.

Neither point blocks this PR; both are follow-ups for the case owner.

Approved after full-diff review and a local run of npm run check. See the detailed review comment above for verification evidence and two non-blocking follow-ups.
