Find non-injected clock / I/O calls (testability)
Recipe ID
org.openrewrite.kotlin.interop.FindClockAndTestabilityFriction$KtRecipeArtifact
io.moderne.recipe:recipes-kotlinSystem.currentTimeMillis() / System.nanoTime() / LocalDateTime.now() and friends read the system clock implicitly. Each flagged call site is a candidate to receive a Clock (or the JDK java.time.Clock) so tests can advance time deterministically. Also flags BufferedReader.lines() — usually a lineSequence/useLines migration.
