Releasing a new Swift version?

• I have bumped the version in ShopifyCheckoutKit.podspec
• I have bumped the version in platforms/swift/Sources/ShopifyCheckoutKit/ShopifyCheckoutKit.swift
• I have updated the SwiftPM/CocoaPods version snippets in platforms/swift/README.md (major version only)

Releasing a new Embedded Checkout Protocol version?

• I have bumped embeddedCheckoutProtocolAndroid in platforms/android/gradle/libs.versions.toml
• I have updated protocol/languages/kotlin/embedded-checkout-protocol/api/embedded-checkout-protocol.api if the public API changed

Releasing a new Android version?

• I have bumped checkoutKitAndroid in platforms/android/gradle/libs.versions.toml
• I have updated the Gradle/Maven version snippets in platforms/android/README.md

Preflight complete — closing as planned; this draft was disposable and must not merge.

Final result (pipeline fc61aa51): both physical rows green.

Target	Device	Evidence
kotlin	Pixel 9 / Android 17	preload-state-ready → present → checkout visible; runner-enforced Logcat Returning cached preloaded WebView. (concurrent-presentation message absent)
swift	iPhone 15 / iOS 27 Beta	preload-state-ready → present → checkout visible → close → preload-cache-hit marker (SDK cache-hit diagnostic via the configured Logger)

Also established here: BrowserStack Maestro publishes passing-testcase device_log artifacts on Android only; iOS publishes testcase artifacts only for failures, and a WKWebView accessibilityIdentifier set in the hit branch is not exposed in the physical-device accessibility snapshot.

The validated pieces are being harvested into the ks-e2e-preload-sample-markers → ks-e2e-preload-cache-hit-signal → ks-e2e-preload-ready-flow stack; the flow/matrix wiring follows once the Maestro tag stack (#556–#558) lands. Branch retained for reference.
