+| `build-ledger.mjs [--mp <MP 仓库>] [--commit <提交>]` | 扫描源码 `@mp-source <路径> @ <提交>` 标签 + `ledger.manual.json`,生成 `ledger.json`(含上游文件 sha256)并刷新文档表格 |
+| `movieclaw-import.mjs [--repo <MC 仓库>] [--ref v0.27.0] [--check]` | MovieClaw v0.27.0(MIT)站点 YAML → `packages/adapters/src/sites/definitions/*.json` + `manifest.generated.ts`;覆盖层 `movieclaw-overrides/<id>.json`;`--check` 只比较 |
