Band faces now use signed distance to the displaced solid intervals, continuous across bands, so MC interpolates the interface instead of terracing at density levels. The Gradient amplitude is restored to width/8 (about 4 m peak-to-peak at 16 m). Ring/terrace audit at LOD0-8 on the FI floor and SW ceiling passes; negative controls: L30 (rings) and L31 (flat) both fail. Hole/interface audits, 16 passage rows and 24/24 determinism pass. Evaluator 20. Cost vs L31 SW +1.9%, FI +1.5%. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CSFYgsdW8ejZSyiMf4qRSX
