Find runCatching { } smells
Recipe ID
org.openrewrite.kotlin.functional.FindRunCatchingSmells$KtRecipeArtifactio.moderne.recipe:recipes-kotlinSearch-only bundle covering the most common runCatching { } pitfalls: swallowing CancellationException, collapsing failures into null via .getOrNull(), discarding the Result in statement context, log-only handlers that drop the failure on the floor, .onSuccess { } chains with no failure handler, and .getOrThrow() patterns that turn the Result round-trip into pure ceremony.
