Updates
Sparkle updates for Mac notch developers
If you are extending NotNotch, Sparkle updates is a host surface or a documented constraint. Appcast.xml and DMG files are served from the same NotNotch origin as the site.

Host rules
Packages declare placements in manifest.json. Sparkle updates may be openTab, liveActivity, or a first-party module.
Do not disable library validation
Unsigned third-party binaries stay manifest-only. That is intentional.
