+### 2026-06-04 — backend v2.8.75 + frontend v2.8.85/86 — chat search + archive view, template→checkout fix
+
+**backend v2.8.75:** archiveChat is now two-way — PATCH /chat/:id/archive accepts
+`{archived}` (default true); archived:false restores. Powers unarchive.
+**frontend v2.8.85:** template detail — once an item is in the cart the sticky bar
+shows «حذف از سبد» + a primary «مشاهدهٔ سبد و پرداخت» (onOpenCart) so the buyer
+can actually reach checkout (previously the single button just toggled).
+**frontend v2.8.86:** chat list gained a search box (counterpart name + last
+message) and a «گفتگوهای آرشیوشده» row → TelegramArchivedChatsView (lazy
+isArchived=true fetch; per-row unarchive via archiveConversation(id,false)).
+getConversations/archiveConversation actions + useTelegramConversations(archived)
+updated.
+All on the new `main` deploy branch. **Verification:** tsc + eslint clean.
