I know a significant part of the lore.
Pedro Álvares Cabral arrived in Brazil in 1500. That's the official discovery of Brazil.
However it already became scientifically proven that Portugal sailed to Brazil in 1498. There is a letter sent from 1498 in which Portuguese sailors (I can't remember the name but I can easily search) tell the King they have already chartered the American continent from Greenland to the La Plata Basin, around Buenos Aires.
Colombo himself was involved in our pre-Columbian expeditions and when he arrived from the Americas on his first voyage in 1492 he was arrested by the Portuguese in the Azores and then escorted to Lisbon where he arrogantly told our King he had discovered India sailing West.
Our King (D.João II?) told him that it was not India and that those territories were already his (by treaty) and that they were already also discovered.
In the reccords our courtiers told our King to kill Colombus but our King was too Christian and it was already probably known by the Spaniards that he was returning anyway.
In his third voyage (I think 1500) it's the first time he lands on American continent instead of islands.
And he openly writes (Colombus does) that he went West into the American continent to see if it was like the Portuguese King had said or if he could find a passage beyond towards a more recognisable (and rich) part of India.
We also have in the 1470s / 1480s the letters with the Italian scholar Ramusio and our King in which they openly talk about the "Eastern Beach" - purportedly of the North American continent.
