Candidates are the FinalImage of the full set plus one template per active stimulus; the maximum relevance wins.
samplesCount ≥ OR_well_known (default 10). In Poor the threshold does not block; for Food/Water there is a special bypass of weak semantics.

OR_well_known threshold. The frame closes, the next frame opens based on the reply, and the flag OrientationReflex_resumeFullOrAfterWaitingResponse is set → on the next call the full second OR pass runs (hippocampus, awareness, EM saving, a new FO cycle) without the shortened waiting branch.
