Clear logical evidence that Buddha died before Achaemenids captured Gandhara (518 BC)

Buddhist texts talk about mahajanapada era during the time of Buddha, if Buddha had died in 480 BC as projected then that would make him survive 40 years of Persian/achaemenid rule in gandhara and yet gandhara is mentioned as an independent mahajanapada.

The date of 400 BC for Buddha's nirvana would mean that he wasn't even born when gandhara was still an independent kingdom.

There is evidence that 16 Kingdom list was reduced to 12 kingdoms in the buddhist texts and Kambhoja and Gandhara which have been removed.

Another Buddhist text, the Digha Nikaya, mentions only twelve Mahajanapadas from the above list and omits four of them (Assaka, Avanti, Gandhara, and Kamboja).[14]

Avanti was dissolved into magadhan kingdom, and similarly gandhara and kambhoja were captured by the achaemenid so they were removed as well.

This is a very insightful post by you, but I beg you not to go by Wikipedia accounts other than for providing a rough outline and perhaps hints towards a basic bibliography.
