CExpertSignalAIBase (4,326 lines, one class) carried 5 struct
definitions, 10 member fields, and 3 methods (Flatten/Unflatten/
PerturbRandom) purely for the AutoTuneIndicators search-space state -
entirely self-contained (never touches Net, Train()'s resumable state
machine, or anything else in the class). Extracted into a new
Expert/ADIndicatorTuner.mqh (CADIndicatorTuner), held as a single
m_indicatorTuner member.
TuneIndicatorsAndTrain() itself - the outer loop that actually
orchestrates Train()/Net/checkpointing around this tuner - turned out
to be exactly as tightly coupled to Train()'s resumable state machine
as Train() itself, so per the same caution already applied to Train()
in this refactor pass, it stays in CExpertSignalAIBase rather than
being pulled into the collaborator; it now calls the tuner's public
Flatten()/Unflatten()/PerturbRandom()/SaveAsBest()/RestoreBest()
instead of manipulating the structs inline.
All internal field-access renames (m_adCumDeltaParams.lookback ->
m_indicatorTuner.adCumDelta.lookback, etc., ~40 sites across the 5
InitAD*() indicator-setup methods) verified against a full grep sweep
- no leftover references to the old field/method names. Compiled
clean (MetaEditor, 0 errors/0 warnings).
