1// nx_autoopt_library_test.nx -- the team builds its OWN optimization library, autonomously.
2// No hand-authored answers: it sweeps a family of kernels it chose (x*C, C=2..13),
3// and for EACH the GENERATOR (superopt) authors the shortest program, the ENGINEER
4// (execution) verifies it 1:1 on held-out inputs, and the verified-optimal machine code is
5// BANKED into a persistent library. The team also KNOWS its own coverage: a kernel it can't
6// reach within its search depth is recorded as a GAP (self-knowledge, not a failure), which
7// is exactly the signal for self-directed escalation. Who wrote the answers? The team did.
8// Gate: every kernel it CLAIMS to have solved is verified by execution -> exit 0.
