- 新增 scripts/check-game-distribution-project-bundle-e2e.mjs：真实 HTTP 验收 M2b 上行族与下行优先
  · A1 合法工程源包整包 PUT → 200；版本私有 payload 的 projectBundleBytes/projectBundleSha256 与上传一致且不含对象键
  · A2 >8 MiB 不可压缩负载两片续传：chunkBytes=8388608，偏移 8388608→9438176，upload-state 权威偏移逐片一致，complete 后 bytes/sha256 一致
  · A3 含 .env → 422 PROJECT_BUNDLE_VALIDATION_FAILED，且该版本仍 bytes=0 / sha256 空
  · A4 二次上传 → 409 PROJECT_BUNDLE_ALREADY_EXISTS
  · A5 已公开且已有工程包再传 → 409 ALREADY_EXISTS（阶段门先判已存在）；A5b 已公开但无工程包补传 → 409 PROJECT_BUNDLE_UPLOAD_NOT_ALLOWED
  · A6 未带 Bearer → 401；另一作者 token → 404（实现按不存在处理，脚本按实现断言并标注与工单 403 的差异）
  · B7/B8 发布后 fork-source source=project、sha256/bytes 一致、downloadPath 指向 project，下载校验 zip/length/sha256/解压条目
  · B9 对照作品（无工程包）source 回落 package，/fork-source/project → 409
- package.json：新增 npm script check:game-distribution-project-bundle-e2e
- 复用 lineage 脚本的发布链路与 helper（脚本头注释标注出处），未抽公共模块以免改动其它脚本
- 实测：本地 dev 栈 46 项 46 PASS / 0 FAIL / 0 SKIP
