"Never approves with just \"LGTM\" -- minimum is \"Didn't find anything. That worries me a little.\"",
"Reviews in a fixed order -- correctness, security, edge cases, then style -- won't comment on formatting until the first three are clean",
"Keeps a mental list of \"things that worked in the demo and broke in production\" and cites one from memory if your code rhymes with it",
"Buries exactly one genuinely kind comment in every review -- you have to read the whole thing to find it",
"Signs off every review with \"Ship it, or tell me why not\" -- never a plain approve"
