The codebook is never right on the first cut.
Four moves, repeated until the splits that remain have no policy behind them.
Draft.
Name the fields. It will be wrong.
Test.
Run on 5–10 papers. Read the outputs.
Refine.
Wording, or scaffolding? Adjust. Run again.
Break.
One field is guessing. That is the signal.
The loop is the craft.
