evaluation4 lines1 sectionsNo variables0 checklist items

Review the implementation against this contract: Normalize spaces and case in invoice numbers. Duplicate identity requires the same supplier and normalized number.
Test this domain failure: Use equal amounts and dates with different invoice numbers. Do not infer an exact duplicate.
Check input citations, calculations, and actual tool logs.
Report unsupported claims and unexecuted tests. Do not approve external actions.
