nx_builder.nx

nx_builder.nx -- the NISHI BUILDER. A sovereign orchestrator that runs the whole closed self-sufficiency loop ITSELF, so the ecosystem builds + races + banks without a human driving each step. For every target it: GENERATES the optimal machine code (the team's chain superoptimizer + emitter), VERIFIES it 1:1 BY EXECUTION (the Engineer), RACES the NEWEST gcc on the box (the team's own gcc-race capability, picking gcc-16/15/14/13), and CLASSIFIES win/tie/loss -- then BANKS the verified-optimal code and FLAGS any loss as the next capability to build. That flag is the loop closing on itself: the builder tells the team where to grow. license_tier: ORIGINAL RACI: GENERATOR authors, ENGINEER verifies, RACER measures the incumbent, the builder orchestrates + banks; it does not fake a result (every banked entry is exec-verified).
