wall_sweep --emit-exclude lists 9 fleet-wide; the list carried 5 of them.
func_8005D734, func_8005D8B4, func_8005ED4C and func_8005F450 each have a
%lo in a branch/jal delay slot — the second half of an assembler macro gcc
emits as ONE atomic insn, so no C can place it there. An agent handed one
returns a NEAR with an unexplainable tail, which is indistinguishable from a
hard function; the playbook measured a main wave spending 4 of 7 slots that way.
