Recent findings (audit lane, verbatim)

Novosibirsk Oblast — The Irtysh River does not flow through Novosibirsk Oblast; the major rivers are the Ob and its tributaries.

Novosibirsk Oblast — The statement that the capital of the Tomsk Governorate was moved to Novonikolayevsk in 1920 is inaccurate; the Tomsk Governorate was abolished in 1920, and Novonikolayevsk became the center of the newly formed Novonikolayevsk Governorate in 1921.

Primorsky Krai — The claim that Primorsky Krai is the birthplace of Kim Jong-il is incorrect; he was born in Vyatskoye, Khabarovsk Krai.

Russian Far East — Primorskaya Oblast was established in 1856 with its administrative center at Khabarovsk. Correction: Primorskaya Oblast was established in 1856, but its administrative center was initially Nikolayevsk-on-Amur, not Khabarovsk. Khabarovsk became the administrati

Russian Far East — The area's largest city is Khabarovsk, followed by Vladivostok. Correction: The largest city in the Russian Far East is Vladivostok, not Khabarovsk. Vladivostok has a larger population than Khabarovsk.

Sakha Republic — The claim that Sakha is the only Russian federal subject that uses more than one time zone is incorrect; several other subjects also span multiple time zones, and Sakha is actually the only one that spans three time zones.

Stavropol Krai — The STATS field 'area_irrigation_canals_2001=3,361 km' is a factual error: it lists a length (km) as an area measurement, and the length of irrigation canals is not a standard or canon fact for Stavropol Krai's area.

Tambov Oblast — The claim that Tambov Oblast has the highest percentage of Russian Orthodox adherents in the whole country is incorrect; other regions have higher or comparable percentages according to the cited survey.

Tambov Oblast — The statement about the defeat and execution of 'Red Sonya' (Sofia Nukhimovna Gel'berg) in the spring of 1918 is not a widely known or established historical fact and lacks reliable sources.

Tomsk Oblast — The oblast is described as being 'southwest of the Siberian Federal District', but Tomsk Oblast is located within the Siberian Federal District, not southwest of it.

Tomsk Oblast — The average annual temperature is given as 1.75 °C, but typical averages range from -0.5 to 1.5 °C.

Tula Oblast — The first reliable mention of Tula is 1382, not 1146, as the 1146 date from the Nikon Chronicle is disputed and considered unreliable.

Tula Oblast — At the time of the 1146 mention, the area was part of the Principality of Chernigov, not the Ryazan Principality.
