WCAG 3.3.4: Error Prevention (Legal, Financial, Data)
WCAG 3.3.4 requires that web submissions involving legal commitments, financial transactions, or sensitive data can be checked, corrected, or reversed before finalization. This protects all users — especially those with cognitive and motor disabilities — from irreversible, high-stakes mistakes.

WCAG 3.3.6: Error Prevention (All)
WCAG 3.3.6 requires that for any web page requiring user input, submissions are reversible, checked for errors with correction guidance, or confirmable before final submission. This AAA criterion extends 3.3.4 to all forms—not just legal or financial ones—protecting users from irreversible mistakes across every interaction.
