Sensitive feedback
"You over-engineered the cache layer"
You loaded their design doc, the refactor PR, and your last 1-on-1 notes. When the feedback moment lands, Minuta drafts: "The concern is not effort; it's impact. The extra cache layer added complexity the team paid for during the refactor, so next time I want you to validate the simpler path first." You edit one phrase and say it. The engineer leaves with the point, not a bruise.
