- App Review's automated check rejected the first submission for importing the private `CGSSetWindowBackgroundBlurRadius`. winit's macOS backend calls it for window blur, and the import stays in the binary although no window here asks for blur.
- Every winit crate is now patched to grmrgecko/winit, which is libcosmic's pinned revision with the private calls removed and blur doing nothing on macOS. The fork has to move whenever the libcosmic revision does.
- The App Store bundle is no longer signed when either executable imports a private window server symbol, so a dependency update cannot bring one back unnoticed.
- The `com.apple.security.network.server` entitlement, which the same check questioned, stays: network ports bind UDP and take incoming sessions. R-110 records the answer given to App Review.
- The App Store variant was only signed ad hoc to run locally, so nothing it produced could be submitted; with a Mac App Store Connect provisioning profile in .signing/app-store.provisionprofile it now embeds the profile, adds the profile's App ID and team to the app's entitlements, signs both executables with the keychain's Apple Distribution identity, and wraps the app in an installer package signed with Mac Installer Distribution.
- A profile whose App ID is not the bundle's is refused, and a missing distribution or installer certificate stops the build rather than producing an unsubmittable package.
- CFBundleVersion becomes the build's UTC time to the minute, since App Store Connect rejects a build number it has seen, while CFBundleShortVersionString stays VERSION; ITSAppUsesNonExemptEncryption is false, as the build's only cryptography is hashing and random numbers.
- The bundled daemon keeps only the sandbox and inherit entitlements, which a helper inheriting its parent's sandbox requires.
- Without a profile the variant builds as before, ad hoc or with MIDI_HARBOR_SIGNING_IDENTITY, to run on the building Mac.
