Classification

Patterns: WRITE task (data mutation, authentication, form submission)
Quality attributes: Functional suitability: correctness and validity (ISO/IEC 25010 | NIST AI RMF: valid)Security (ISO/IEC 25010 | NIST AI RMF: secure and resilient)
Risks mitigated: Form validation errorsPolicy-violating transactions
