 v2.4 decisions:
 
 - Admin role: isAdmin boolean flag on users table (simplest, no Logto role claims needed)
+- Admin grant mechanism: CLI script or seed — no public UI for granting admin
 - Sub-items/component attachment: explicitly deferred to a future milestone
 - Catalog spec system (typed specs per tag): deferred to v2.5
 - Engagement stats (views/likes/saves/appearances): deferred to v2.5
 
 ### Pending Todos
 
-- Fix Add Candidate button shows wrong modal on thread page (ui)
-- Fix item image not showing on collection overview
-- Investigate slow image loading
-- Auth prompt sign-in button should redirect directly to Logto
-- Cursor pointer on all clickable links
