Defensible by designDecisions remain reviewable and evidenced.
Transparent processScope, ownership and boundaries stay visible.
Client-first partnershipWork starts with the operating need.
Secure by defaultAccess and sensitive data stay controlled.Explore authentication, authorisation, sessions, input handling, secrets, dependency risk, tenant isolation, and the places where one system must decide whether another actor or payload is trusted.
