This is a partial cleanup to centralize the initialization and update decisions for AAs. Lifting the burdon and boilerplate on users and making it harder to accidentally perform unsound deductions. The two static helpers show how we can lift the decisions to generate an AA into the Attributor, avoiding trivial AAs that just cost us compile time and maintenance code (to check for pre-conditions).
