The ledger is the product
Most payment platforms fail at the same place: a ledger that was never designed to be one. Here is what a correct money layer looks like, and why it has to come first.

Notes from the engineering room — what we've learned building ledgers, automating decisions and modernising systems nobody dares to touch.

The question is not which tasks a model can perform. It is which decisions your organisation is willing to delegate, and what happens when one of them is wrong.
The system everyone wants to replace is usually the one encoding twenty years of hard-won business rules. Modernise around it before you modernise it.
Intermittent connectivity, fragmented payment rails and hard infrastructure constraints are not limitations. They are a design curriculum.
A design document is not a formality. It is the cheapest place to be wrong. Here is the structure we use on every engagement.
Deployment friction does not just slow releases. It changes what your team is willing to attempt.
