nx_incumbent_gate.nx

nx_incumbent_gate.nx -- GATE for the incumbents ruler (nx_incumbent_lib, engineshift ES28), driven IN-PROCESS on a planted fixture tree under /tmp: thirteen fake organs (a dense-judge twin naming a knowledge/ asset and carrying a rejection line, a cross-encoder twin, a voxel organ, nine fillers, one whose header overruns the read window) and two fake assets. Proves: the index envelope (files, assets, truncation counted, corpus_complete), a rerank contract names both rerank twins and neither the voxel organ nor the excluded organ, the asset named in a matched header is listed, the rejection line is listed, a voxel contract names the voxel organ alone, a nonsense contract prints NONE with its terms, a contract made only of words every header carries is dropped as non-discriminating, the index states (FRESH, STALE by age, ABSENT, MALFORMED), and THE DECLARED ACCEPT RULE on the live tree: the search board's R0 contract, answered from a live index built into /tmp, names nx_dr_densejudge, embed_v1.bin and the DR-13 rejection with no seat input. Every fixture asserts its own condition first. license_tier: ORIGINAL Writes only under /tmp/nx_incumbent_gate. No hw writes (Rule 26).
