+### 2026-06-03 — frontend v2.8.66–67 — seller chat, header bell, cart UX + review system audit
+
+**v2.8.66:** seller rows in the Mini App shop get a chat icon (direct conversation with the
+seller); header gets a notification bell opening the in-shell notifications list.
+**v2.8.67 fixes:** seller chat gave "Validation failed" (backend expects ONE participant for
+direct chats — current user auto-added; we sent two). Cart «−» at qty 1 now removes the item
+(separate remove button dropped). Bell: borderless + red dot instead of count.
+**Review/rating system audit completed (agent):** backend schema/API/store fully working
+(reviews table, /api/marketplace/reviews). Broken: seller rating HARDCODED 4.5 in
+DrizzleMarketplaceRepo.findSellersWithActiveRequestTemplates (never reads real reviews);
+review form never sends purchaseRequestId (verified-buyer badge never set); Step 6
+post-delivery has NO review prompt; Mini App has no reviews. Full phased plan in agent output —
+next work items.
