about
nx_emu_x86_cf_test.nx -- x86 full-system ladder R2: CONTROL FLOW. A self-contained x86-64
interpreter that adds flags (ZF/SF) + cmp + conditional/uncond jumps to the R1 straight-line set,
so it executes real LOOPS. KAT: an authored x86 loop computes sum(1..10)=55 (register-only, no
memory yet). Kept separate so the foundational nx_emu_x86 stays untouched (Rule 3/19).
HONEST SCOPE: control flow only; memory load/store (R3), modes (R5), devices (R7), boot (R8+) are
later rungs. No hardware writes (Rule 26). expect_exit: 0 license_tier: ORIGINAL
