Find reactive / coroutine interop hazards
Recipe ID
org.openrewrite.kotlin.spring.FindReactiveCoroutineInterop$KtRecipeArtifact
io.moderne.recipe:recipes-kotlinBridges between Reactor and coroutines that usually point at a missed opportunity: WebClient.bodyToMono(...).block() (use awaitBody<T>()), Mono.deferContextual { } inside a suspend fun (context propagation goes through coroutineContext), and awaitSingle() patterns worth a review.
