nx_connect_lanes_lib.nx

nx_connect_lanes_lib.nx -- the per-relationship INTENT-LANE consent state machine, extracted as a shared library so the verifying gate (nx_connect_lanes) and the LIVE app (nx_connect_serve /lanes) bind ONE implementation. Until this split the capability had NO user-facing surface at all. This is the honest, consented alternative to a banned-but-leaking dating lane (Tandem admits theirs persists; HelloTalk's intent toggle is cosmetic). A relationship's ACTIVE lane is the level BOTH parties have opted into -- MIN(a_request, b_request) -- so ESCALATION REQUIRES MUTUAL CONSENT and nobody can be pulled toward romance unilaterally. DE-ESCALATION and BLOCK are UNILATERAL and immediate: the asymmetry is the point, hard to escalate and easy to exit. Any relationship involving a MINOR is hard-capped below the romance lane, so dating is structurally unreachable rather than discouraged. Lanes: LANGUAGE(0) < FRIEND(1) < COMMUNITY(2) < DATE(3). Integer state logic only. license_tier: ORIGINAL
