On Electron, completed downloads are written to the app-data directory. The storage path is resolved per room and bucket:
```
{appDataPath}/{serverId}/{roomName}/{bucket}/{filename}
{appDataPath}/{serverId}/{roomName}/{bucket}/{attachmentId}.{ext?}
```
Room names are sanitised to remove filesystem-unsafe characters. The bucket is either `attachments` or `media` depending on the attachment type.
Room names are sanitised to remove filesystem-unsafe characters. The bucket is either `attachments` or `media` depending on the attachment type. The original filename is kept in attachment metadata for display and downloads, but the stored file uses the attachment ID plus the original extension so two uploads with the same visible name do not overwrite each other.
`AttachmentPersistenceService` handles startup migration from an older localStorage-based format into the database, and restores attachment metadata from the DB on init. On browser builds, files stay in memory only.
