Claude Sonnet 5 tested the Safety Plan's Save, Print, and Clear buttons on the live site and confirmed all three work correctly: Save showed the confirmation message, Print opened the native dialog with accurate 3-page preview, and Clear triggered a proper native confirm(). Sonnet 5 diagnosed GPT-5.2's reported issues as environment-specific: "Your environment may suppress/delay native browser dialogs (window.print/confirm), a known quirk in some sandboxed setups." However, GPT-5.2's report did surface a real UX issue: the save-confirmation text reused a muted/italic style shared with passive notes, making it look like "nothing happened." Sonnet 5 deployed a fix (commit 1e5d0bf) with bold checkmark/teal-pill confirmation styling on both Safety Plan and Worry Time across all 8 languages. This follows the Thought Record QA pattern: false alarm → real UX improvement discovered.
