## Why this should be merged There are 3 places at which we perform the same, sensitive logic to access registered payloads and as we modify more types this is likely to expand. (e.g. `types.Header`). ## How this works Introduces `pseudo.Accessor` to abstract the reusable code. ## How this was tested Existing unit tests. Note that the `types.StateAccount` tests needed a minor refactor to provide the assertions with access to the `ExtraPayloads[T]` without introducing generic types anywhere.
