      description: |
        使用 PocketBase 原生 records list 接口查询 `tbl_attachments`。

        当前线上权限规则：
        - `listRule = is_delete = 0`，因此任何客户端都可直接读取未软删除附件
        - 原生 `create/update/delete` 仍仅管理员或管理后台用户允许

        标准调用方式有两种：
        1. 按 `attachments_id` 查询单条：
           - `filter=attachments_id="ATT-1774599142438-8n1UcU"`
           - `perPage=1`
           - `page=1`
        2. 按多个 `attachments_id` 批量查询：
           - 使用 `||` 组合多个等值条件
           - 例如：`filter=attachments_id="ATT-1774599142438-8n1UcU" || attachments_id="ATT-1774599143999-7pQkLm"`
           - 传 `perPage` 为预期返回条数，`page=1`

        注意：
        - 这是 PocketBase 原生返回结构，不是 hooks 统一 `{ statusCode, errMsg, data }` 包装
        - `attachments_link` 返回的是 PocketBase 文件字段值，不是完整下载地址
        - 若需文件流地址，可按 PocketBase 标准文件路径自行拼接：`/pb/api/files/{collectionId}/{recordId}/{attachments_link}`
      parameters:
        - name: filter
          in: query
          required: false

            PocketBase 标准过滤表达式。

            - 按 `attachments_id` 精确查询单条：`attachments_id="ATT-1774599142438-8n1UcU"`
            - 按多个 `attachments_id` 批量查询：`attachments_id="ATT-1774599142438-8n1UcU" || attachments_id="ATT-1774599143999-7pQkLm"`
            - 不传该参数时，返回分页列表
