Rules
A rule is a sentence about your data, not a config file.
Eight worked examples, in the schema the gateway actually accepts. Each one names what it matches and what it does — cache it, refuse it, or retire what a write has already made false — because a rule you cannot explain is a rule nobody will turn on.
These are examples. Yours come from your own query history.
The scan reads what actually repeats in your account and writes the rules that would capture it — ranked, with what each one alone is worth.
