nx_engineer_reproduce.nx

nx_engineer_reproduce.nx -- the ENGINEER autonomously REPRODUCES Claude's fresh methods on NEW targets, closing the training loop with ZERO Claude authoring the content. For each of the 5 fresh engineer methods it EMITS a real .nx organ that genuinely APPLIES the method, GOD-BUILDS it (fork rv64im->nx_cc->nxasm, no gcc), and keys on the emitted gate's OWN exit code. Each GREEN reproduction is a real compiled+asserting organ on disk => nx_team_train re-grades ENGINEER toward 5/5. Emit/build pattern = the proven nx_god_cycle. E0 find-existing-first -> check existence BEFORE authoring (dup REFUSE / novel ALLOW) E1 extend-not-copy -> a base verdict + a RAISED bar that rejects a case the base accepted E2 gate-with-liar-kill -> a verdict that FLIPS when its data is corrupted E3 measured-exceed -> margin = improvements - regressions on a labeled set, liar-killed E4 never-brick(#26) -> a hardware op without a never-brick proof is REJECTED despite good quality Sovereign. license_tier: ORIGINAL
