# A_Memorix 配置参考 (v2.0.0)

本文档对应当前仓库代码（`__version__ = 2.0.0`、`SCHEMA_VERSION = 8`）。

说明：

- 本文只覆盖 **当前运行时实际读取** 的配置键。
- 旧版 `/query`、`/memory`、`/visualize` 命令体系相关配置，不再作为主路径说明。
- 未配置的键会回退到代码默认值。

## 11. 兼容性提示

- 若你从 `1.x` 升级，请优先运行：

```bash
python plugins/A_memorix/scripts/release_vnext_migrate.py preflight --strict
python plugins/A_memorix/scripts/release_vnext_migrate.py migrate --verify-after
python plugins/A_memorix/scripts/release_vnext_migrate.py verify --strict
```

- 启动前再执行：

```bash
python plugins/A_memorix/scripts/runtime_self_check.py --json
```

以避免 embedding 维度与向量库不匹配导致运行时异常。
