This article translates the temporal doctrine established in Time, Consistency, and Freshness in a Financial Services Data Platform into enforceable architectural mechanisms. It focuses not on tools or technologies, but on the structural controls required to make time, consistency, and freshness unavoidable properties of a Financial Services (FS) data platform. The objective is simple: ensure that temporal correctness does not depend on developer discipline, operational goodwill, or institutional memory, but is instead enforced mechanically by the platform itself.
