void	invalidate_engine_clones () const
	Drops the cached per-worker criterion clones of every engine (see Candidate_Evaluator::invalidate_clones()). The threaded engine re-uses its clones across batches while the same criterion object is supplied, so once the ORIGINAL criterion's evaluation context has changed - the next trial's depth-0 split, a re-estimated filter model, a re-tuned classifier or regressor parameter - the clones must be re-made from it, or the workers keep evaluating in the old context: without this call a threaded trial protocol repeats its first trial in every trial. A no-op for the sequential engine.

Public Attributes
std::shared_ptr< ACCESSOR_MEM >	da_mem
	concrete-side handle: initialize(), setSplittingDepth()
std::shared_ptr< DATAACCESSOR >	da
	the type-erased handle every component sees
std::shared_ptr< CRITERION >	crit
	counting decorator around the selected criterion
std::shared_ptr< CLASSIFIER >	clf
	the wrapper criterion's classifier (empty for filters); --validate same reuses it
std::shared_ptr< REGRESSOR >	regr
	the type-erased regressor handle (--validate same on the regression pipelines)
std::string	regr_label
	its validation-entry label ("regressor" \| "ridge")
std::shared_ptr< RWN >	rwn
	concrete regressor handle (only where the concrete API is needed: the kernel-multiplier sweep)
std::shared_ptr< SVM >	svm
	concrete SVM handle (parameter optimization needs the non-erased type)
std::shared_ptr< RBFSVM >	rbfsvm
	concrete native RBF SVM handle (--rbfsvm-optimize needs the non-erased type)
std::shared_ptr< std::atomic< long long > >	evals
	shared evaluation counter, incremented by the counting criterion decorator; feeds the "evaluations" stats field
std::function< bool(RETURNTYPE &, const std::shared_ptr< SUBSET > &)>	split_eval
	re-evaluates a subset on the accessor's current split
std::function< void()>	crit_reinit
	re-estimates a filter criterion's model on the current split (per-trial re-init, demo55-B); empty for wrappers
std::shared_ptr< SEARCH >	search
	the constructed search algorithm
std::shared_ptr< TRACKER >	tracker
	dupless-family handle (top_k source); null for stabileval
std::shared_ptr< TRACKER_REG >	tracker_reg
	regularizer handle (optimize_within_margin)
std::shared_ptr< TRACKER_STABIL >	tracker_stabil
	stability-evaluator handle (manual add per trial)
std::shared_ptr< TRACKER_STATS >	tracker_stats
	feature-stats handle (compute_stats, DAF extraction)
std::shared_ptr< WEIGHTER_SAMPLED >	sampled_stats
	sampled-evaluator statistics engine (the warm-up probe loop feeds it)
PENGINE	sampled_engine
	the sampled evaluator's candidate-evaluation engine; the threaded warm-up loop reuses it so criterion clones persist into the search
std::vector< PENGINE >	engines
	every candidate-evaluation engine built for this run (the search's and the step evaluator's), registered by make_engine() so that invalidate_engine_clones() reaches them all
