#49 FIXED + OPERATOR-VERIFIED: the radar draws the static world again -- walls, buttes, hills, ridges, buildings, trees. Root cause (radar/map drift audit, 3-agent, receipts in scratchpad/night17/radar_audit_*.txt): the original filed every pip-bearing Terrain-GRAPH entity into the gauge staticEntities grid via the interest feed (@004cbfa0: pip gate, Mover->moving / Terrain->static; the derivation graph parents UnscalableTerrain 0x2A + CulturalIcon 0x5E + Landmark 0x56 onto Terrain [T0 TERRAIN.cpp:183]), and MapDisplay::DrawStatic (@004c25b4) drew each entity's AUTHORED vector-outline pip (110 type-0x12 GIMs ship: wall1-3, aw01-05 arena walls, buttea-e, hillg/dhillg, sr1e/n/s/w polar ridges, trees, buildings) world-rotated and metre-scaled. The port's RebuildEntityGrid (the shim replacing the dropped interest feed) iterated DYNAMIC entities only -- the 1008 statically-registered UnscalableTerrain instances never reached the grid, so the scope showed no world at all. Fix: a third pass files non-dynamic Terrain-graph entities from HostManager::AllEntityIterator; pipless entities (floors, sky, the wall10k outer fence -- authentically invisible on the shipped radar too) no-op at the pip lookup exactly as on the machine. Receipts: [map-grid] worldStatics census + a capped per-static [map] dump (cls/rid/pip/dsq) symmetric to DrawMoving's. Benched: grass files cls=42 hill rid=2190 pip=1 drawing at 466m beside 313 trees; arena1 files 126 world statics with the aw wall sections (rid 1918/1915) pip=1 drawing and the unpipped walkway/banner props correctly skipped (authored omissions preserved). Operator-verified live on arena1: 'muuuuch better'.
