Independent Staging Quality Gate run 2683 唯一失败： database-consultation-session-capacity 期望 false:session_missing， 实际是 f:session_missing。夹具把 boolean::text 的 false 规范成 psql -A 的 f。 五处期望值对齐既有合同；无 Docker 源码合同锁住 false→f。
Replace append_consultation_question so the 200,000 quota sums only user-visible text, and add a 1,000,000-byte whole-JSON physical cap. Both still return session_full. Advisory lock, request_id idempotency, and the 200-message cap are unchanged.
