Problem
A team got burned by duplicate rows from append-only writes and disabled all retries. Now every transient blip pages a human at 3 a.m. who hits 'rerun' manually. The section names this exact mistake (treating the symptom, not the cause) and frames the fix as a two-way contract. Apply both halves of the contract on the canvas.
