M3 U9 存量回填、migration corpus 与数据生命周期

目标

只保留可解释的演示/回归数据，并持续验证旧数据迁移、重载和受控恢复。backfill 可暂停续跑，异常进 quarantine；八条轨道可重复；销毁默认 fail closed。

范围

• dataset registry（pinned / demo / regression / migration_baseline / ephemeral / quarantine）
• checkpoint 分批 backfill：只枚举 snapshot、approved/commit event、completed chat turn
• SKIP LOCKED 多 worker；禁止扫描 workspace
• 销毁门禁：FAV coverage + 完整备份 restore + corpus + 精确 manifest + 双人批准 + quarantine 观察窗
• restore 拒绝共享 env DSN；只允许 scratch
• 八轨：clean / oldest-supported / previous / hazard / import / reload / rollback / artifact recovery

非目标

• U10–U12；不碰 chat / intent mutex
• 不整支 merge feature/final-artifact-vault；不启用 FAV_DEGRADED_READ
• 不修改历史 Goose；不销毁 agent_system_dev/test/main
• 不终止或改写项目 143；worktree 内禁止 env-service

步骤

1. CURRENT 认领 mutex=dataset；从 dev 开 feature/dataset-lifecycle-u9
2. Goose 00038 + module-boundaries.yaml
3. internal/artifactvault/backfill.go + internal/dataset + cmd/dataset
4. 硬化 scripts/restore-system-db-drill.sh
5. 隔离库 + 八轨 + 目标包 -race + 占槽 rebuild
6. 验收报告；最后一句 继续 U10

验收标准

• backfill 中断、重复、并发新终态时分母/分子可复算且不重复 artifact
• legacy-v0 / 旧 schema / 高 ID / projection fork / 缺 snapshot → quarantine 或升级
• restore 拒绝共享 DSN、错误 storage identity、篡改 manifest、缺权限
• coverage / backup / corpus 任一失败阻止 destroy
• 批准 dataset 导入后关系、SHA、sequence 可复算
