Research direction
Investigate the DelimiterFraming implementation in Akka Streams (likely in akka stream/src/main/scala/akka/stream/impl/fusing/) to understand how oversized lines are currently handled. Look at the Resume supervision directive in the context of flow processing. Consider how dropping bytes until a new delimiter can be integrated without breaking existing behavior. Review any related discussions in the issue comments for additional context.
