(subprocess.run/Popen/call/os.system sabotage 활성 — 실제 spawn 시 RuntimeError)
[L1-1] build_launcher_fn(CANONICAL_ROOT) [flag 부재] = None  (기대 None=ACTIVE false)
       read_real_wake_enabled(CANONICAL_ROOT)=False ✓ (프로덕션 entrypoint default 동작 무변경)
[L1-2] flag on + sealed key 부재 → None  (기대 None fail-closed, real wake 0)
