nx_wordclust_gate.nx

nx_wordclust_gate.nx -- GATE for the PPMI word clusterer (nx_wordclust), driven IN-PROCESS on a PLANTED NXPPMI1 model under /tmp/nx_wordclust_gate (six words, three orthogonal context vectors, written by the library's own fixture writer through the ONE loader's format). Proves: the fixture is read back by the canonical loader, words the model knows resolve and one it does not reads -1, k-medoids at K=3 groups the three synonym pairs and separates the three pairs, a word unseen at build time is assigned on demand to its pair's cluster, ids spell as two bytes and -1 as one, two builds agree, and a missing model fails closed (no clusters, never a crash). Every fixture asserts its own condition first. No network. license_tier: ORIGINAL No hw writes (Rule 26).
