about

nx_build_bench.nx -- MEASURE the build/compile pipeline speed, per phase, natively. Times the two sovereign build phases the WOMB runs, with the clock read IN-ORGAN (sys_now_ms) around each fork+exec (sovereign, not a host stopwatch): PHASE 1 compile : _offc/nx_cc_sovereign.elf <module.nx> (stdout -> /tmp/<m>.s) PHASE 2 assemble: _offc/nxasm_x86_main.elf <m>.s <m>.elf Reports compile_ms / assemble_ms / .s+.elf bytes / throughput across a small, medium, and large organ, and names the bottleneck -- so build-speed optimization is evidence-based, not "30 is ok". Sovereign: imports only nx_syscalls. license_tier: ORIGINAL
