Worker B's maspsx structural limitation recorded: a region needing
addu-encoded moves (maspsx expands move->addu, GNU as expands move->or)
AND an assembler-filled jr slot cannot be matched with any single
maspsx= setting — this explains a family of epilogue residuals. B
verified in .s files. Two negatives with mechanisms (0x800254B0 alloc,
0x800751E8 with negu — evidence FOR the toolchain, finding-26 route).
B self-corrected an invented-address method error. Gate MATCH whole-
binary SHA-1 e173426c157384ebf1b6caf8c6fea18a85a14af9.
