For Android, record the module applicationId, namespace, min/target SDK, versionCode/versionName, and compare applicationId with the published Play identity; Android's docs say applicationId uniquely identifies the app on-device and in Play, and changing it after publication creates a new Play app. Record the actual release artifact (signed AAB/APK), signingReport output, certificate fingerprints, keystore ownership, and whether Play App Signing separates an upload key from the app-signing key; debug-signed builds are not publishable. If the channel is Google Play, record the Play Console track and inspect Play-generated split APKs/device coverage rather than treating a local AAB as the shipped binary. For iOS, record CFBundleIdentifier, version/build, supported destinations, team, signing/provisioning, and the matching App Store Connect app record; Apple requires a matching bundle ID and says it cannot change after the first upload. Record the beta/release channel (TestFlight, store, or outside-store export) separately. For runtime provenance, record framework and toolchain versions from lockfiles and build logs. Current React Native setup guidance is platform-dependent (Node 22.11+, JDK 17, Android SDK 35/Build Tools 36, latest Xcode; a Mac is required for native iOS builds), while Flutter distinguishes debug/profile/release and says mobile release mode is not supported on simulators/emulators. For every row, attach source/config/build/store evidence, timestamp, environment, and an explicit unknown/partial state; a green UI or successful debug run does not prove release identity, signing continuity, store registration, or backend parity. Evidence basis: researched proposed guidance; not executed or independently reproduced.
