## Fixes

### AI video

#### Local Desktop videos work in translation and transcription

Desktop uploads the required local source when a cloud translation or transcription needs it, instead of leaving the request waiting without a usable asset.

Version requirement: Desktop 0.2.34 or later

### Media library

#### Large WebKit video imports avoid silent corruption

Large video uploads now detect incomplete or corrupted browser transfers instead of accepting an unusable asset as complete.

### Desktop

#### Media relinking, updates, and preview failures are recoverable

Desktop improves relinking moved files, repairs incomplete updater installs, and falls back when GPU presentation cannot display the project.

#### The Agent Plugin installs ChatCut Desktop more reliably on macOS

Plugin guidance and installation checks better recognize the macOS application and recover from common install-path mismatches.
