"Every simplification hides a choice about what to ignore.
In a scaling issue where efficiency and resilience pull apart, the conversation keeps returning to what you do not know. The practical question is what you will do anyway.
A team can handle bad news. What it cannot handle is ambiguity that keeps reopening the same argument. Clarity removes noise faster than reassurance does. Write it for the person who inherits it later, because they will not have today’s context or today’s goodwill. A standard you cannot apply in one pass is not a standard; it is a preference disguised as governance.
Put the assumption into words, then choose the signal that forces you to revisit it. That is what makes execution calmer. Let the boundary do the work.
