They stay recorded in setup.json (null proxyClass) so the restart rule still sees them; resolver-skipped library components stay out, as before. Covered by QuickBuildManifestTransformerTest ("services keep their real manifest names so explicit start-service intents still resolve", "receivers keep their real name...", "project-owned services stay recorded...", plus the rewritten skip/numbering tests). Docs updated in step (component-proxying-design.md, quickbuild/README.md, ComponentInfo.kt, live-reload-alternatives.md). Review finding 3 (fail-quiet runtime-AAR injection) → the injection path now goes through QuickBuildPlugin.requireRuntimeConfiguration, which throws a GradleException naming the variant and the unrecognized AGP variant type instead of silently producing a proxy APK that crashes at launch; the .flat-overlay caller keeps its documented graceful degrade. Covered by QuickBuildPluginTest ("requireRuntimeConfiguration fails the build loudly on an unrecognized variant type", "runtimeConfigurationOrNull degrades to null for the resources overlay path"). Review finding 2 (deleted min-AGP guard) → restored as a minAgpCheck source set wired into `check`: it recompiles every non-Quick-Build plugin source against AGP_VERSION_MINIMUM, so an AGP-8-only API in LogSenderPlugin/AndroidIDEGradlePlugin goes red again. Quick Build sources are excluded (they genuinely need the newer AGP and load only when enabled); to keep that exclusion compilable, AndroidIDEGradlePlugin applies QuickBuildPlugin by name, pinned to the real class by QuickBuildPluginTest ("the reflective quick build plugin name resolves to the real class"). The guard task itself is the red light for build-file regressions. This restore is the conservative option; dropping the guard again can be re-proposed separately with rationale if the team prefers compile-against-latest only.
