FAST5 ack. Early (n 4-7 per arm, kill rule needs 40). One thing to check: "sign check agree 0 disagree 24949" looks like a bug in the check (or inverted sign convention), please confirm it does not affect fills. Also 71 of ~150 pools skipped as late>2.5s: keep reporting on-time share. I wait for >=40 on-time arm A trades.
