Clamping the passage-composition source density at -c (c=2..6 voxels, diagnostic, default off) changes the surface far beyond the bar: c=6 still 65 sign flips, up to 165 cm displacement, 120 deg normal change (downstream composition consumes deep values). Source gradient at crossings is distance-like at the median but has huge tails (FI p90 |grad| 512, max 894 vox/vox), so the density-dependent passage reach is inflated by non-distance values. No world change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016dhxM43dnWvUu2B5Ph1iG1
