// @brief Abstract interface for pluggable sample transformation in the routing service.
//
// A TransformPlugin receives a raw CDR payload (as received from the input DataReader)
// and may mutate it in-place before it is forwarded to the output DataWriter.
// Returning false drops the sample entirely.
