Maybe the solution is to have a = defined way to import an unknown wallet?

This means that the gap = space and a search ordering needs to be defined.

Given a = blockchain and a root seed, it should be possible to find all the = addresses for that root seed.

The hierarchy that the wallet actually uses could be = anything.
