Practice Catalog
Seventy-six cards,
six drawers, one index.
Every practice Jer Durfee consults on is a numbered card in a named drawer — engaged under a written scope, delivered against a defined question, and filed when it closes. Licensed-adjacent practices (actuarial, customs, nuclear, veterinary) advise within their boundaries; credentialed specialists sign their own work.

Librarian's Note
Bounded cards carry boundaries.
Cards marked "Bounded" — actuarial (non-insurance), financial management (non-investment-advice), customs, nuclear and veterinary — advise within consulting scope only. Actuarial opinions for insurance belong to credentialed actuaries; customs work belongs to licensed brokers where the law requires it; veterinary diagnosis belongs to licensed veterinarians. Request a card and the librarian will confirm the right drawer before any scope is written.
