I wouldn't put too much thought into it. Page count's are kinda random and they may be listing the ebook page count which would make it one of the longest ones in the series. Either way though all the Alcatraz books are quite short. All five of them together are going to be roughly the same length as a single Stormlight book.

From what I've read Hoid is actually a title passed from master to student. Although throughout the cosmere stories Hoid is in fact the same person. The only exception I know of is in the Liar of Partinel. That novel (unreleased) has a Hoid who is thought to be the teacher of the Hoid in all other cosmere novels. Brandon Sanderson has said that the Hoid from the published stories was present at the shattering so it's fair to say the Hoid in all published cosmere stories is all the same person.

There is also the Mistborn Adventure game. A House of Ashes includes a story in the Mistborn universe although I'm not clear if Brandon Sanderson wrote any of it or merely OK it for release. In addition to that there is also the Allomancer Jak and the Pits of Eltania story which is partially available on his site and the rest (I think) is included in an expansion to the board game. This entire story I believe is written by Brandon Sanderson himself.

Does that mean episodes 1-26 don't actually exist? Or are they available somewhere else?

Does anyone have more information on this? Even the coppermind doesn't mention this piece. The official site offers chapters 28-30 but that's the only time chapters are even mentioned. My understanding is the text posted on Brandon's site is suppose to continue from the story that was on the long sheet in Alloy of Law. Does that mean the Alloy of Law has chapters 24-27?
