the second A-source prefetch left the corresponding address operand unused.
Public Duck sources have no separate software license; inherited attribution
and license notices remain below.
Idea: Delete only the now-unused pfy register input and its address formation
from the carried A kernel. No assembly instruction references that operand,
but its r constraint still makes GCC compute and retain it across every call.
Purpose: Release a real general register and remove dead address preparation
around the register-constrained carrying kernel; verify generated instruction
and stack-access reductions, full output equality and the official result.

engine and B-delta specialization. Inherited source/author notices retained.
Public Duck source states no separate license.
Idea: The plain kernel already terminates via its negative byte index and
never reads or writes its old K operand. Delete that unused read-write asm
operand and its initialization. A is likewise unchanged by the indexed body,
so declare A as an input instead of a modified early-clobber output. Retain
all real cursor, vector, flag and memory effects and the assembly verbatim.
Purpose: Remove a redundant register/initialization and forced A copies from
the inlined plain callers, without changing arithmetic or memory accesses.
