  Before AI rewrites legacy SQL, make review inspectable first: deterministic payloads, graphs, and readiness cues—not assumption-heavy diffs alone.

• Shape Parity Is Not Semantic Parity

  When base group counts stay stable but derived totals drift, downstream filters can collapse the output without a failed job.
