Formulas and processes
Calculators state their units, assumptions, rounding, and operational boundaries. CSV tools parse files in the browser and leave the source unchanged.
Testing
Important calculations use known fixtures and boundary cases. Worked examples are checked against the same pure calculation functions used by the page.
Sources and limits
Guides prefer official safety rules, equipment documentation, and primary technical references. Outputs never replace rack engineering, fire review, equipment limits, source-system controls, or qualified judgment.
Review dates
Dates change only when substantive claims are reviewed. No public corrections channel is configured, so this site does not invent a contact identity.
