    Variable SEGMENT_ORIGINSConst

    SEGMENT_ORIGINS: 32

    Origins per segment. A walk-forward is cut into segments of this many consecutive origins; each starts cold (the grid alone) and warm-starts from the previous origin inside it. The cut depends on the history only — never on how many cores run it — so the answer is the same in-process and on any number of workers.
