Companion Resource

The living companion to the book

Copyable prompts, downloadable datasets, and the reconciliation checkpoints that let you prove your work. The book is the frozen part; this is the part that stays current. Everything here is free, and the book never depends on it.

The one rule. Every figure a model returns is a draft until it reconciles to a control total you reached another way. The datasets and checkpoints here are those control totals.
