Bounded vertical route partition / streaming for handcrafted spiral climb maps (Only Up / Only Climb). Not World Partition, not Level Instances as core arch. - Z-cell segmentation + optional XY subcells, editor builder + commandlet - NonDestructive visibility backend + streaming-level backend - Offline HLOD proxies: MergedMesh / SimplifiedProxy (ProxyLOD) - Universal Level Instance + Packed Level Actor + HISM support (flatten+merge) - Vertical-aware runtime streamer (full/preload/HLOD/unload, hysteresis, velocity prediction, fall-risk), WP-style debug viz + vp.* console - Safe-by-default: only static decor streams; sky/lights/gameplay stay persistent Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
