The transaction sequences reshape now fetches transactions from the archive.

Browse Source 
This is required as it's the only place that holds the original order of each block's transactions. We cannot sort them, because the comparator function for transactions has some dependencies on the existing order for AT transactions. As a result, topOnly nodes cannot perform this reshape, and will be unable to run this version.
