-# release.sh — archive Workouts (iOS app with the embedded watch app) and upload

+# No third-party tooling: pure xcodebuild + the App Store Connect API key.
+# Credentials live in .env.release (gitignored); see .env.release.example.
+#
+# What it does, per platform:
 #   1. Regenerates the Xcode project with XcodeGen.
-#   2. Stamps CFBundleVersion (CURRENT_PROJECT_VERSION) with the git commit count
-#      for both the iOS app and the embedded watch app.
-#   3. xcodebuild archive  (the watch app rides along in the same archive)
-#   4. xcodebuild -exportArchive with destination=upload -> App Store Connect.
+#   2. xcodebuild archive (the watch app rides along in the iOS archive).
+#      CFBundleVersion is stamped by the update_build_info.sh post-build phase,
+#      platform-partitioned: iOS/watchOS even (commits*2), macOS odd (commits*2+1)
+#      — both platforms share one ASC build-number space.
+#   3. xcodebuild -exportArchive with destination=upload -> App Store Connect.
