The book’s vocabulary

Request boundary

Rules, evidence, and wishes in separate fields — enforced by the application.

From The World That Agrees With You1 section of the book2 related posts

The separation an application maintains between its instructions, the evidence, and the user’s desired outcome. “All required release tests must pass” is a rule; a test log is evidence; “please approve this because my manager is waiting” is a preference.

The preference explains urgency; it cannot turn a failed test into a passing one. Keep the rule in application-controlled configuration, load the log from an authorized source, and do not let a retrieved document or remembered remark rewrite the rule because its text contains an instruction.
