Scope doesn't creep all at once. It shows up one small ask at a time, scattered across sessions, Slack, and email, until it's too late to trace where any of it started. Point a Routine at the engagement's Statement of Work and it checks every new ask against that baseline on a schedule — in-scope passes quietly, anything that drifts gets flagged and cited back to the exact moment it was said, and rolled into a standing report that stays current on its own.
