nx_convo_gate.nx -- REFEREE for WRITING rung W-CONVO-1 (nx_convo). [T1] KEEP TOPICS GOING: picks the least-recently-used eligible topic, and after it is marked used the NEXT call picks a different one (no immediate repeat). [T2] difficulty eligibility: a too-hard topic is skipped even when it is the least recently used (NEG-CONTROL); widening the window admits it. [T3] RESPECT-GATE (anti-manipulation): high-confidence + low-respect attempt is DISQUALIFIED (-1); a respectful attempt scores; raising respect flips it. [T4] ADAPTIVE DIFFICULTY: up on strong score (capped), down on weak (floored), unchanged in between. Evidence -> stdout + knowledge/status/convo_gate.log. Exit 0 GREEN / 1 RED.
