An unsourced claim and a well-sourced claim read identically in an AI-written summary — that's the trap. The discipline is tagging every claim with where it came from and how much you'd bet on it, before it goes anywhere near a decision.
A simple three-tier habit works: "verified" (you checked the primary source yourself), "reported" (a source you trust said it, unchecked), "inferred" (the model connected dots that weren't stated outright). Mixing these without labeling them is how confident-sounding nonsense gets into a deck.
Run the seed, then tag every claim in the output with one of the three tiers before you'd let it near a real memo.
