nx_team_selfsufficient_test.nx

nx_team_selfsufficient_test.nx -- the team runs the WHOLE cycle itself and builds ON its own output. Self-sufficiency = no human in the per-task loop AND the bank feeds future work (it grows UP, not just sideways). PHASE 1 (autonomous backlog): for each goal -> GENERATE (synth from examples) -> VERIFY (held-out) -> GOVERN (crew council) -> BANK into a reusable library. PHASE 2 (build on itself): COMPOSE two BANKED primitives into a NEW capability the team was never given -- 2x . x^2 = 2*x^2 -- and verify it. The team extended itself from what it had banked. I wrote no program and ran no step by hand here; the loop generated, proved, governed, banked, and composed. Known answer: backlog all banked, the composite verified, library grew by the backlog + 1 -> exit 0.
