Aux Proton Bridge v0.1.0

Aux Proton Bridge v0.1.0

Engineering MVP / private beta foundation for an unofficial Linux desktop bridge over Proton Drive.

What works

• GUI wrapper over Proton's official proton-drive CLI
• Proton browser login/logout via the CLI
• /my-files listing
• Download selected files/folders
• Download all visible /my-files entries
• Upload local files/folders
• Choose/open local destination folder
• Activity log
• Serialized Proton CLI queue to reduce SQLite cache-lock conflicts
• Conservative transfer defaults: merge folders, skip existing files

Security model

• The app does not ask for or store Proton passwords.
• Proton authentication remains in the official CLI's OS secret store.
• Renderer nodeIntegration is disabled.
• Context isolation is enabled.
• CLI commands are executed as argv arrays, not shell strings.

Verified locally

• npm run check passed
• npm audit --json reported 0 vulnerabilities
• npm run smoke:source passed
• npm run smoke:appimage passed
• cd dist && sha256sum -c SHA256SUMS.txt passed

Limitations

• Not yet a true bidirectional sync daemon.
• Deletes are not automated.
• Conflict behavior is intentionally conservative.
• Packages are unsigned.
• Tested on Fedora 44 x64 build host; wider distro qualification remains pending.
