All three mission drivers re-run against the rebuilt release binary
after 51096a3/a20b6f6/4897919: the synthetic poison row now shows

single-window case reads "the single walk-forward window recorded
zero trades", and the marker-separability log still greps into two
clean classes. Captures refreshed in place; the milestone fieldtest
roll-up is green. refs #278, refs #313
