what no source draws

• {'sought': 'Bering Strait, as an area', 'source': 'naturalearth-10m marine and regions', 'why': 'Neither layer carries it: the marine gazetteer names 32 straits worldwide and not this one, and hydrographic sources generally draw a strait as a line between two capes rather than as an extent. The map therefore frames the strait, without claiming a boundary nothing in hand draws.'}
• {'sought': 'Kerek speaker area', 'source': 'asher2007', 'why': 'No polygon in Asher 2007.'}
• {'sought': 'Chuvan speaker area', 'source': 'asher2007', 'why': 'No polygon in Asher 2007.'}
• {'sought': 'Siberian Yupik speaker area', 'source': 'asher2007', 'why': "The book's “Asiatic Eskimo”. Asher 2007 draws the Alaskan Yupik varieties and no Asian one; they are its comparanda, not substitutes for it."}
• {'sought': 'Tundra (Northern) Yukaghir speaker area', 'source': 'asher2007', 'why': 'Asher 2007 draws Southern Yukaghir only.'}
