Building BuchhalterPython: Architecture Before the First Commit (Part 2)

Part 2 of the BuchhalterPython series. Part 1 covers how we set up agentic infrastructure — six specialised agents, golden standards, and token optimisation — before writing any application code. We spent a full day on architecture before writing a single line of business logic. No features, no endpoints, no database schemas. Just decisions. By the end of that day, we had five architectural choices that each prevented at least one production failure. Three of those failures would have been silent.
