Policy 3 (headless + Unreal): walkable ring always first; at rest/arrival LOD0-2 before far; walking interleaves near:far ~4:1 toward heading; fast travel admits far coarse tiles right after the walkable ring. Hysteresis: walking 0.75/0.35 m/s, fast 12/8 m/s. Headless, far holes while moving 30 m/s: L77 9.0% / L79 77.2% / L80 8.9%. Cold LOD0-2 ready (one clean protocol, medians): SW 1.30, FI 3.61, TN 3.07, VS 1.43 s. Unreal 30 m/s traces end 2,233/2,237 loaded (commandlet readiness exit 1) for all policies. Passage zero-padding cut: ~50% fewer passage iterations on active tiles, max 6.6 cm surface displacement, no sign flips; not adopted yet (padding sweep next). World unchanged (v213).
