UNCONVERGED screening seed for gauntlet relaxation. Exact registry survivor 01ecdf8e525f whose author-confirmed chart coordinate (AlB2 20%, F/(F+E) 100%: F=1 shared face, E=0 corner edges) targets a BLANK chart cell. Local conservative-20 OMat staged relaxation reached max force 1.25 eV/A at step 10 with B CN9 2/2, Fe CN12 4/4 and the seed F/E coordinate intact; further local steps broke Fe CN12, so this checkpoint is supplied for the stronger conservative-inf MPA gauntlet. Mo-B-Fe boride, B on TCTP roles. Raw SHA-256 ee7d284134d1ac98c9216ba62c68cbc3ed0d419951052f62c258671a7ed3e241
