It iterates all the rules. Then applies the first where all conditions specified.
The implementation seems.... clunky.
Worse, is maintaining the set of rules in the database.
Its a relational set of tables. Each rule has a set of rule components. To satisfy a rule means every comp must pass.
Authoring rules is laborious. Theyre sorted by an 'ordinal' column at runtime. Its just kind of a mess.
