# UX acceptance criteria

Use this pattern:

`Given <user and context>, when <task or event>, the user can <observable outcome> without <critical failure>, while the system provides <necessary feedback, control, or recovery>.`

Add a numerical threshold only when baseline, risk, contractual requirement, or decision power justifies it. Otherwise define the measurement and decision rule first.

Each criterion must trace to a finding and include test method, required state, evidence captured, and failure interpretation.
