Wire TY_ARRAY into the existing struct-return gates so arrays ride the same reg-class (<=24B in AX:DX:CX) / sret-class (>24B) path the struct return ABI already emits byte-identically. No new ABI machinery. Both stages, uniform gate-widen: - cg_sret_retsize / sretretsize: +TY_ARRAY (natural size sub.size*len, the type table) -> auto-enables sret send/recv + the >24B sret N_IDENT word-copy + return-forward, all keyed on the shared sret SSoT. - cgreturn <=24B reg-send: +TY_ARRAY (N_IDENT scratch word-copy -> AX/DX/CX). reg-class return-forward rides the default cgexpr passthrough. - let-init / assign <=24B recv: +TY_ARRAY (AX/DX/CX sized stores). struct_float_class stays struct-only: pure-int element arrays only; no pure-float-array-return consumer exists today. 949 +11 rows: reg-class 8/16/24B + sret-class 32B, [N]u32 and [N]u8, at let-init/assign/return-forward, full-member readback, + a struct- return regression control. All cstage-run + cs==ww byte-id.
