nx_cc_splice_bisect.nx

nx_cc_splice_bisect.nx -- PER-FUNCTION COMPILER-CODEGEN BISECTOR. Team organ (Doctor's localizer, sibling of nx_cc_equiv_gate): when a challenger compiler's output misbehaves, this finds WHICH function's codegen carries the defect -- no awk, no shell loops, pure NishiLang file IO + fork/execve/wait4 (sovereign judging law). Method (asm splice): for every function whose body DIFFERS between the two asm files, build a FRANKEN image = base.s with only that one function's body replaced by the donor's, assemble+link it, and run the franken compiler on a probe source. A function is a BREAKER iff its splice alone flips the probe verdict. Functions are self-contained ABI units, so single-function splices are valid experiment isolation. Born 2026-06-10 bisecting the awakened-LICM self-host breakage (ledger T#opt-dom-licm-dormant-paths): corpus rows all GREEN, self-host RED -- the defect lives in specific big-function hoists, and this organ names them. Usage: nx_cc_splice_bisect <base.s> <donor.s> [probe.nx] base.s asm of the BLESSED compiler compiling some source donor.s asm of the CHALLENGER compiling the SAME source probe.nx source the franken compiler must still compile (default runtime/_derefcast_minrepro.nx; compile rc 0 + non-empty asm = behaves) Exit 0 iff NO breaker found (prints/logs the per-function table to knowledge/status/cc_splice_bisect.log either way). license_tier: ORIGINAL
