Keep exact original files and the browser backup ZIP separately. The source and result JSON preserves parsed values, frozen rules, complete findings and any transformed or sampled output. Review unresolved rows before relying on results. The formal reports are bounded summaries. No import, registry check, formula calculation, macro execution or external connection occurred. Mechanical checks use customer-selected rules and exact source values. They do not authenticate records, establish a complete population, validate an identifier registry, approve an import, or determine compliance. Original files remain unchanged in this browser.
