The blue body labelled Lake Baikal on Vibes of Cosmos, World Map 2025, its adjoining western source-water reach and a northern river branch follow the original map's visible blue strokes. The lake name is read from that source; its depicted placement and shape are not conventional survey registration.
Two reviewed gates add 1,181 native source pixels while retaining earlier water. The lake's printed name is separate from its blue body and is excluded. The nearby Lena River-name contact, isolated fragments and ambiguous source strokes remain unchanged. Red city markers and visible land are protected. No obscured water joins are invented.
The existing renderer water datum is retained; actual lake elevation, depth, bathymetry and flow are not modelled. No new relief, settlements or building detail is introduced. Source-drawn widths and broad terrain softness remain limitations.
