ASF counterpart: apache#525 (ready for review; current-head CI and remaining acceptance are open).

The earlier guidance required ownership on older Servers and extended restore/cleanup guarantees. Scope the proposed protection to ordinary Loader processes sharing one live Server graph instance; older Servers and graph-source/restore imports keep their existing behavior.

Only an explicitly unsupported ownership-route 404 selects the legacy ordinary mode flow. Other errors remain failures. Explain the same-handle/principal owner lifecycle and manual REST release recovery, without automatic expiry, cross-Server coordination or a full shutdown/drain guarantee.

Paired implementations: Server #3331 and Client/Loader #815. Released packages and current master lack this owner protection. Hubble task cleanup #814 remains a separate change.

Validation: strict Hugo 0.165 Extended build, repository link checks, bilingual rendered-page checks and a fresh independent documentation review. Current-head CI and coordinated implementation/documentation merges remain open.

Summary by CodeRabbit

  • 文档
    • 补充 LOADING 所有权协议与并发导入行为说明,包括所有者申请、共享及释放后图模式的变化。
    • 明确普通导入仅在接口返回 404 时回退旧流程;权限、网络及其他错误仍会失败。
    • 说明手动设置图模式、图数据源与恢复导入的行为,以及所有权机制的适用范围和异常恢复方式。

- document protocol 1 and matching client/server requirements
- describe fixed owner lifecycle and permissions
- clarify abnormal exit recovery and deployment limits

998-998: 🎯 Functional Correctness

为“重启 Server 恢复”补充实现依据,否则删除该建议。

graphs.md 只定义了手动释放接口,没有说明 Server 重启会清除 owner 状态。请确认 Server 的实际行为,并统一使用“Server”,不要同时使用“图实例”。
