 ## Node 脚本

+### 发布冲突自动迁移
+
+`npm run spacetime:publish:maincloud` 默认采用冲突感知发布：
+
+1. 先不清库发布新 wasm。
+2. 如果发布成功，流程结束。
+3. 如果发布失败且输出可判定为 schema 冲突，脚本自动导出旧库迁移 JSON 到 `tmp/spacetime-migrations/maincloud/<database>/<timestamp>.json`。
+4. 导出成功后执行清库发布新 wasm。
+5. 新 wasm 发布成功后，把第 3 步导出的 JSON 自动导入回灌。
+
+任一阶段失败都会中止流程，并保留已经导出的迁移 JSON。非 schema 冲突的发布失败不会进入迁移流程。
+
+```bash
+npm run spacetime:publish:maincloud -- --database xushi-p4wfr
+```
+
+可选参数：
+
+- `--no-migrate-on-conflict`：禁用冲突自动迁移，只保留原始发布失败。
+- `--migration-dir <dir>`：指定迁移 JSON 输出目录。
+- `--clear-database`：显式清库发布；该模式代表人工确认清库，不触发自动迁移。
+
+冲突自动迁移需要发布脚本本次生成的 `GENARRATIVE_SPACETIME_MIGRATION_BOOTSTRAP_SECRET`。因此不要和 `--no-migration-bootstrap-secret` 同时使用。
+
+### 删除表和删除字段
+
+迁移文件来自旧模块时，可能包含新模块已经删除的表或字段。导入阶段按以下规则处理：
+
+- 迁移文件包含新模块已删除或不在白名单内的表时，不中断迁移；该表全部行计入 `skipped_row_count`，并在导入结束后统一展示 `dropped_table` 告警。
+- 迁移行包含新模块已删除的旧字段时，导入 procedure 会尝试丢弃旧字段后继续反序列化；恢复成功则导入该行，并在导入结束后统一展示 `dropped_field` 告警。
+- 新模块新增必填字段、字段类型变化、枚举不兼容等无法通过“丢弃旧字段”恢复的情况仍会失败并回滚，避免写入不完整数据。
+
 本机导出时，先确保本机 SpacetimeDB 服务和源数据库可访问，然后授权本机调用身份：
