harden

Strengthen interfaces against edge cases, errors, internationalization issues, and real-world usage scenarios that break idealized designs.

Assess Hardening Needs

Identify weaknesses and edge cases:

1. Test with extreme inputs:

   • Very long text (names, descriptions, titles)
   • Very short text (empty, single character)
   • Special characters (emoji, RTL text, accents)
   • Large numbers (millions, billions)
   • Many items (1000+ list items, 50+ options)
   • No data (empty states)

2. Test error scenarios:

   • Network failures (offline, slow, timeout)
   • API errors (400, 401, 403, 404, 500)
   • Validation errors
   • Permission errors
