The structural audit loop audits one leader per cluster per round and, when that leader is related (TM >= .45), promotes the next member. A large cluster that is structurally related to a query but carries no shared Rfam family or clan therefore advanced one member per round: the NuFold predicted-database fit at --audit-ceiling 100 still had 5 unaudited leaders after 70 of its 75 rounds (about 13 minutes each).

When a leader is flagged, also audit every unaudited, scored, eligible mate in its cluster with E0 <= ceiling. Mates score no higher than the eligible leader, so these are the audits later rounds would request; a mate with TM < .45 stays in the background exactly as an unaudited one. On NuFold the loop now settles in 2 rounds at ceiling 100 and in 5 at ceiling 400 (212,859 -> 3,726 -> 57 -> 2 -> 0 pairs).

The predicted fit takes max_rounds like the experimental one (default 75, as before) and both report the round limit when the audit does not settle.
