Four clear reaches of the Lena, Yenisei and Ob networks follow visible blue strokes on Vibes of Cosmos, World Map 2025. Names and placement follow that source, rather than conventional survey registration.
Four reviewed gates restore 1,100 native source pixels: 269 along the western Lena reach, 363 across two Yenisei reaches and 468 in the western Ob network. Gates stop at lettering, ambiguous drawings and other source interruptions. These are bounded reaches, not complete river networks. No obscured joins are invented. Existing water, land and city markers remain protected.
The existing renderer water datum is retained; actual elevations, depth and flow are not modelled. No relief, settlements or building detail is added. Source-drawn widths and broad terrain softness remain limitations.
