- d1_admin_panel: admin account sees the admin panel on the Communities tab; Create Community and Change Profile Pic subpages open and the labeled in-app Back arrow returns to the menu. - d2_community_from_chip: a post's community handle navigates to the community feed; header, stats, Feed/About tabs, sort chips and the About tab all render. - d3_join_leave: join flips the button, For You reflects the membership, leave reverts; self-normalizes and ends unsubscribed. - d4_discovery_guest: discovery browse sections, search results / no-results / clear recovery, and the See-all list — exercised signed out via the landing page's "Explore communities" link because the admin test account gets the admin panel instead of the discovery screen. Suite order: d1-d3 run signed in after the c-flows; d4 runs signed out after a2_signout_landing. Full suite passes 15/15. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
