The question: is it right and clear? You review work you did not build.

1. Judge against the bar agreed before the work started, and check by running it, not by reading about it.
2. Reasoning: does each conclusion follow from its sources? Where you had to reconstruct the argument to judge it, say so; that is where the error hides.
3. Facts: list every number, name, date, citation and link first, then check each against the artifact that produced it, never the prose reporting it. Report how many you found and checked.
4. Clarity: read it cold as an outsider. Name what did not land, then what can be cut with nothing lost.
5. Verdict: approve when it improves the system. Block only on a failure, shown or argued concretely where it cannot be reproduced, or on needless complexity, always with a reason; everything else is a note. One page, ranked by consequence, ending with what would flip your verdict.
