This section is a detailed walk-through of the hook’s internal math, calculation flow, and key design decisions. It’s the heart of the hook. This is where all the magic happens. The contract is built so that all calculations live in separate modules. I hope this breakdown of the math, the alternatives considered, the modular library structure, and the MIT license make it easy to either contribute to the project or freely adapt it to any needs. The Median, Snapshot, and Curve pages cover the solutions I chose. The Alternatives pages cover the other approaches I considered but rejected, and why.
