These include APK binary size, method count diffs, full dependency graph changes, and merged manifest diffs. The goal is to make implicit side effects of code changes visible at review time rather than discovering them late in the release process. More detailed data like full method diffs, ProGuard reports, and resource shrinker output are attached to CI build artifacts for deeper investigation. ## Full article daily.dev links to this article rather than hosting it.
