There was a problem hiding this comment.
ExternalData is the only struct that has an alignment different than 1.

Problem
Many of the
structs of the program are interpreted directly from bytes assuming 1-byte alignment. In some cases, structs have constraints that their size must match. While these are correct in the implementation, there are no checks to ensure they remain valid in case of future updates.Solution
Add
constasserts on structs.
