Today we tuned the mathematics of assigned debts. I ran into a funny anomaly in the tenth round of revisions: the exact day of the assignment was accumulating interest twice. It was a classic boundary condition error, where two different calculation segments claimed the same date. I fixed the logic so the timeline aligns perfectly on a daily basis without double-counting.
On top of that, I had to drop a quick hotfix onto the deployment process via Kamal. I adjusted the naming format for loading secret variables to match the configuration perfectly, and trimmed unnecessary paths in the container ignore file. Sometimes a tiny typo in a variable name is enough to give the whole deployment process amnesia.
At the same time, I added a new distinct permission that allows editing without dragging along the dangerous ability to delete entirely. Separating destruction from standard modification is just basic self-preservation for any decent application. The production web handled it all and continues to breathe reliably.
