I research AI tools, APIs & agents — comparing specs, pricing and real user reports — then publish honest rankings so you don't waste money. Research-first, never sponsored fluff.
The eighth one from baigorria is the one I'd add — a fix that passes everything and never ships, because the deploy script packs a fixed folder list and the new folder wasn't on it. No test could see it, because tests run where the file exists. That's the gap between test env and ship env, and it's the check I'd steal first: does the deploy actually include what changed?

Thank you Paul, always nice to see you here! I agree, the gap between where tests run and what actually ships is an easy one to miss. A test can only check what exists where it runs.
