Zero Formula Errors

• Every Excel model MUST be delivered with ZERO formula errors (#REF!, #DIV/0!, #VALUE!, #N/A, #NAME?)
• Always verify with: Spreadsheet { action: "check_errors", file_path: "output.xlsx" }

Preserve Existing Templates (when updating templates)

• Study and EXACTLY match existing format, style, and conventions when modifying files

• Existing template conventions ALWAYS override these guidelines
