apple build exports each build into build/ios/export/<version>-<build>/ (cleaned first), runs xcodebuild with Apple's tool folders first on PATH (Homebrew rsync 3.x broke Xcode's IPA step: exportArchive Copy failed), shows the IDEDistribution log's real error lines and exits non-zero on any export failure; apple upload fails with exit 1 when the IPA's build number is already on App Store Connect (stale IPA after a failed build), --allow-existing re-checks, --build N picks that build's IPA, release and beta flows use both; doctor flags a non-Apple rsync first on PATH; desktop publish calls rsync by absolute path without --chmod (publishSteps); site download notice per OS (macOS signed and notarized, Windows unsigned for now, Linux unsigned); game-report credential tests hermetic against a machine default profile (pitfalls 53, 54)
