This is really neat, and actually pretty sophisticated. It's like a tiny fintech.

How well has the cash flow prediction worked?

It's great because Claude Code generated complex analysis/models 10X better than I was familiar with.

The key was normalizing the payee/categories so we can analyze month to month, and separating fixed vs variable spend. It then did a fancy Monte Carlo simulation with the computed mean/stddev per payee. And out came T+30/T+60 estimates at P50/P80/P90.
