Recent findings (audit lane, verbatim)

Naoko Takeuchi — The claim that Takeuchi wrote the ending theme song 'Moonbow' for Sailor Moon Crystal under the pen name Sumire Shirobara is incorrect; 'Moonbow' is from the musicals, not Crystal, and Sumire Shirobara is used for musical lyrics, not Crystal anime themes.

Naoko Takeuchi — The claim that her studio Princess Naoko Planning (PNP) also manages the work of her husband, Yoshihiro Togashi, is unsubstantiated and likely incorrect; PNP primarily manages Takeuchi's own properties, while Togashi's work is managed by Shueisha.

John Tenniel — The entry states Tenniel was the first illustrator or cartoonist to be knighted, but this is not accurate; while he was the first to be knighted for his work as a cartoonist/illustrator, earlier illustrators (e.g., Sir Edwin Landseer, who was knighted in 1850)

John Tenniel — The entry says 'The first print run of Alice's Adventures in Wonderland was sold in the United States because Tenniel objected to the print quality.' This is incorrect; the first print run was withdrawn and sold in the United States because Tenniel objected to

Alessandro Algardi — Algardi apprenticed in the studio of Agostino Carracci, but Agostino Carracci died in 1602, before Algardi was born; the correct master is Ludovico Carracci.

Alessandro Algardi — Ferdinando I, Duke of Mantua, died in 1612, when Algardi was 17, not 'by age twenty'; the correct patron was Ferdinando Gonzaga, Duke of Mantua (reigned 1612–1626).

Antonio Canova — The entry states that Canova advised that the Elgin Marbles be acquired by the British Museum with plaster copies sent to Florence, but this specific detail about Florence is unsupported by standard historical accounts.

Donatello — Donatello's first documentary appearance is not in January 1401 in Pistoia; the earliest known record is from 1404–1407 when he was an apprentice in Ghiberti's workshop.

Donatello — Donatello and Brunelleschi did not return to Florence in early 1401 after the Baptistery doors competition; the competition was held in 1401–1402, and their trip to Rome is generally dated to around 1402–1404.

Jean-Antoine Houdon — The entry states Houdon studied under Jean-Baptiste Pigalle, which is not supported by standard sources.

Claus Sluter — The Well of Moses was created for the Carthusian monastery of Champmol, which was founded by Philip the Bold in 1385, not 1383.

Claus Sluter — The specific dates 1736–1789 and the cause of the cross's destruction (roof collapse) are not universally established; the destruction is often attributed to the French Revolution or earlier neglect, and the roof collapse theory is speculative.

Bertel Thorvaldsen — Thorvaldsen's birth date is not disputed between 1770 and 1768; he was born on 19 November 1770, and the 1768 date is a common error with no credible support.

Bertel Thorvaldsen — Thorvaldsen was not the only non-Catholic artist commissioned for a work in St. Peter's Basilica; other non-Catholic artists, such as Antonio Canova (who was Catholic but not exclusively), also received commissions, and the claim of 'only non-Catholic' is not
