Block-code search derived from the 18125=29*25^2 witness. Searched by deleting whole 4-point blocks and refilling with movable anchors and the library of 4-point mod-29 cores. The resulting 100-point witness simplifies completely: it is 25 translates of the single core 25*{0,1,5,6}. This extends the 100-point deformation ladder to N=18025.
