About this template
Diff is ground truth. Claims are suspects.
If you review agent PRs and need a second pair of eyes on claims, this is for you.
Agents invent confidence. This template treats git diff as ground truth: compare the PR body or chat summary to what actually changed. Flag mismatches. You decide merge.
