Universal Conversion hub and foundation pages render without errors
Phase 13.0 QA
Universal Conversion Quality Gate
Foundation checks for the Universal Conversion platform before length, area, volume, weight, temperature, speed, pressure, energy, power, time, data, cooking, currency, and scientific converter rollout.
Required checks
Shared unit-family framework covers length, area, volume, weight, temperature, speed, pressure, energy, power, time, data storage, cooking, currency, and scientific units
Converter UI supports value, source unit, target unit, result card, explanation, and next-step guidance
Validation rules cover empty values, non-numeric values, negative values where invalid, incompatible unit families, precision, and formula-based conversions
Conversion pages are namespaced to Phase 13.0 and do not interfere with Finance, Health, Business, Education, Engineering, or Construction platforms
Sitemap and index-control entries are registered
Tools index is regenerated or confirmed with the new conversion category framework
No duplicate slugs introduced
PHP syntax and JavaScript syntax checks pass
Compatibility boundary
Phase 13.0 is namespaced with tb130 functions, tb130 CSS classes, and tb130 JavaScript helpers so existing Finance, Health, Business, Education, Engineering, and Construction platforms continue to work without namespace collision.
