When the boundary is unwritten, people optimize for what is legible and defensible, not for what is true. That is how you get busywork and brittle systems. Write it down because otherwise two reasonable engineers will execute two different interpretations, and the system will call it “miscommunication.” A standard you cannot apply in one pass is not a standard; it is a preference disguised as governance.
Name the assumption and the observable signal that would invalidate it. That is how you keep pressure from rewriting the decision. Clarity reduces noise more than another meeting does.
