The protocol ledger is maintained as a primary research record in the source repository. This page provides a stable documentation-site entry point without duplicating or silently modifying that record.
The documented count is 193 evaluations across the main recorded families, plus an earlier carpet search of about 128 level-3 configurations and an unrecorded level-4 sweep. The cumulative figure is therefore stated as at least about 321, not as an exact exhaustive total.
