nx_connect_graph.nx

nx_connect_graph.nx -- R4 of CONNECT: the UNIFIED heterogeneous interest graph (HIN) + one meta-path matching model. The core product promise: incumbents SILO language / hobby / faith / dating as separate products or flat filters; we put person + language + hobby + faith + place on ONE graph and match across all of them with ONE model, parameterized by the relationship LANE. A person is a node; attributes are typed edges (teach/learn-language, likes-hobby, faith, place). Meta-path connection strengths (integer, no floats): reciprocal-language (the R1 path), shared- hobby, shared-faith, co-location. gx_graph_score(A,B,lane) combines them with LANE-appropriate weights -- so the SAME model serves language-exchange, friendship, community and dating. Proven here: (1) it GENERALIZES R1 -- the language lane still requires reciprocal language; (2) it UNIFIES across silos -- a pair with NO shared language but strong shared hobby+faith is found for the friendship lane, where a language-only matcher returns nothing; (3) faith is CONSENT-GATED (contributes only if BOTH opted into faith discovery -- GDPR Art.9 by construction); (4) the minor<->romance safety wall is preserved. 7 checks incl. negative controls. (DRY note: the small match primitives are re-stated here to keep the gate self-contained; production extracts them into a shared library organ.) 100% sovereign. license_tier: ORIGINAL expect_exit: 0
