The global tagged ident operand read saved BP instead of the global: 'is' compared garbage as the tag; 'as' never had a payload. Route the load through the g(SB) base — tag at +0, payload at +8, cap at +16 for str (one mechanism, both consumers). The 'is' half aligns ww UP (cs==ww pinned); the 'as' half is a both-wrong pair — cstage spills an uninitialized payload register (its N_TYPEASSERT assumes cgexpr filled AX/DX/CX; filed as task #46), so its rows assert ww-runtime-correct with the cs divergence documented until #46 lands. Review item #18.
