Overview

Base class for all data and byte mutators. Incorporates Radamsa-inspired dynamic adaptive scoring (2..10) coupled with user-configurable priority weights for intelligent selection.

abstract def mutate(context : Context, buffer : Buffer, target_range : Tuple(Int32, Int32) | Nil = nil) : Tuple(Bool, Int32) #

Performs mutation on buffer, optionally constrained to target_range [start, end_exclusive]. Returns a tuple of {success : Bool, score_delta : Int32}. score_delta > 0 indicates success in an appropriate domain (+1 or +2). score_delta < 0 indicates the input does not match the mutator's domain (-1).
