1// nx_mc_fix.nx -- MC-applier gate FIXTURE (mock buildonly): argv[1]=target. Reads the shared "lib"
2// file /tmp/mc_shared and writes its content (or "GONE" if absent) to /tmp/<target>.sov.elf, so each
3// importer's artifact DEPENDS on the shared lib -> retiring mc_shared changes every artifact (REFUSE),
4// retiring an unrelated file changes none (CONSOLIDATED). exit 0.
5// license_tier: ORIGINAL   No hw writes (Rule 26).
