1/4 What do you do when every finance app can explain where your money went—but none can tell you whether the next purchase is safe?

My money lives across banks, cash, cards and currencies. I wanted one explainable answer, so I built a small read-only system to give me one. 🧵

4/4 This is a personal system built around my messy finances—not a polished universal product. I open-sourced the approach in case it helps someone with the same problem.

3/4 The system combines owned funds, cash, dated income, rent, card payments and a savings reserve into an explainable 30-day forecast.

I can inspect it from a PWA or ask Codex through MCP. The point is to see what happens after the next purchase—not just where money went.
