Different settings, same discipline.

A household, a clinic, a hiring system, a payment app, a game platform, and an agent runtime do not need the same data. A bouncer and a bank do not need the same fields. A smart speaker and a pair of smart glasses do not serve the same rules. What they share is the shape of the exchange: scoped context arrives, the relevant parts get verified, the irrelevant parts stay out of scope, and the result gets recorded. The setting changes. The discipline holds.
