We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Scaffolding — The claim that Daniel Palmer Jones's company supplied scaffolding for the reconstruction of Buckingham Palace in 1913 is unsubstantiated and likely invented.
Scaffolding — The entry incorrectly includes 'Tubular Scaffolding Company' as one of Daniel Palmer Jones's companies; this entity is not recognized in the historical lineage.
Screw — The claim that the first documentation of the screwdriver is in the medieval Housebook of Wolfegg Castle is incorrect; earlier references exist, such as in the works of Leonardo da Vinci or earlier manuscripts.
Screw — The statement that the left-side pedal of a bicycle has a left-hand thread as a definitive fact is misleading, as many modern bicycles use right-hand threads on both pedals with a different mechanism.
Screw mechanism — The entry states the screw first appeared in Mesopotamia during the Neo-Assyrian period (911-609 BC), but the earliest known evidence of the screw is from the Hellenistic period, around the 3rd century BC.
Screw mechanism — The entry claims the water screw was first used in Ancient Egypt before Archimedes described it, but there is no reliable historical evidence for the water screw in Ancient Egypt predating Archimedes.
