## Access Grant Table
| **Column Name** | **Data Type** | **Constraints** | **Description** |
| --------------- | ------------- | ----------------------- | ------------------------------------------------------ |
| id | Integer | PRIMARY KEY, AUTOINCREMENT | Unique identifier |
| resource_type | Text | NOT NULL | Type of resource (e.g., `model`, `knowledge`, `tool`) |
| resource_id | Text | NOT NULL | ID of the specific resource |
| principal_type | Text | NOT NULL | Type of grantee: `user` or `group` |
| principal_id | Text | NOT NULL | ID of the user or group (or `*` for public) |
| permission | Text | NOT NULL | Permission level: `read` or `write` |
| created_at | BigInteger | nullable | Grant creation timestamp |
Things to know about the access_grant table:
- Unique constraint on (`resource_type`, `resource_id`, `principal_type`, `principal_id`, `permission`) to prevent duplicate grants
- Indexed on (`resource_type`, `resource_id`) and (`principal_type`, `principal_id`) for efficient lookups
- Replaces the former `access_control` JSON column that was previously embedded in each resource table
- `principal_type` of `user` with `principal_id` of `*` represents public (open) access
- Supports both group-level and individual user-level access grants

The `access_control` fields expected structure:
```python
{
"read": {
"group_ids": ["group_id1", "group_id2"],
"user_ids": ["user_id1", "user_id2"]
},
"write": {
"group_ids": ["group_id1", "group_id2"],
"user_ids": ["user_id1", "user_id2"]
}
}
```
Access control for resources (models, knowledge bases, tools, prompts, notes, files, channels) is managed through the `access_grant` table rather than embedded JSON. Each grant entry specifies a resource, a principal (user or group), and a permission level (read or write). See the [Access Grant Table](#access-grant-table) section above for details.
