Neither paper is an offer to sell anything. There is no public sale of ATON and there was no private round. The only ways to get it are to mine it, or to buy it on the open market once it is listed.
Most of what they describe does not exist yet. Where something is a plan rather than a working thing, both papers say so, and the technical one lists every parameter that is still open in a single table. The build tracker is the current position, computed from the code rather than written by us.
They will be revised. Every revision goes in the public changelog with a date, so nobody has to wonder whether a paper always said what it says now.
