🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

Reviewed the Accessibility Disclaimer copy update and the new debug-menu reset affordance. The change splits the disclosure body into three strings, renames the accept action/callback to "I understand", and adds a resetAccessibilityDisclaimer debug option. Verified the removed accessibility_disclosure_start_up_text string has no remaining Kotlin references (lingering entries in values-* files are Crowdin-managed translations and expected), the retained accept string is still used elsewhere, and tests were updated to match the renamed action and new debug button.

Code Review Details

No blocking findings. The change is well-scoped, follows existing screen/ViewModel/repository patterns, and includes corresponding test updates for the renamed action and the new debug-menu option.
