25 renames (git mv, content untouched). _test.ww is what the package coordinator's test detection and the sep loader's canonical exclusion key on; the old *test.ww spellings survived only through the line-leading-@test compatibility scan. Consumers updated in place: LIBRARY_TESTS, the libbyteid roster, the 901/974/975/976 carriers that copy or invoke these files, and the check.c/check.ww + path/ftos comments that cite them. Closes the open-driver-work migration bullet.
