Dividend Terms, Metrics, and Rules

[victoriajackson]

The 'coming to terms' framing is useful, especially for newcomers who hit the Chowder, Graham, and Tweed names with no context. A short note on the logic behind each rule, even without sourcing, would make the terms list far more approachable. On the database: I agree that documenting the schema and queries while the extract is fresh is worth it, since a long break tends to erase the reasoning, not just the momentum. The point that building the extract is the hard part sounds right; the processing layer can be reworked later.
