+# Phase 8: Grouped Chat UI — Detailed Implementation Plan
+
+## Overview
+
+Add UI for organizing chat sessions into collapsible groups.
+
+**Data available:**
+- `SessionEntry.groupSlug` — null for ungrouped, string for grouped
+- `GroupEntry` — `{ name, slug, description, createdAt, updatedAt, sessionCount }`
+- `useChatGroups()` hook — `{ groups, createGroup, updateGroup, deleteGroup, moveSession }`
+
+---
+
+## Phase 8.1: Grouped SessionList UI
+
+**File:** `src/apps/officer-web/Screens/Dashboard/ChatHistory/Screen.tsx`
+
+### Changes
+
+1. **Import `useChatGroups`** alongside `useChatSessions`
+
+2. **Group sessions by `groupSlug`:**
+```ts
+const ungrouped = sessions.filter(s => !s.groupSlug);
+const grouped = groups.map(g => ({
+  ...g,
+  sessions: sessions.filter(s => s.groupSlug === g.slug)
+}));
+```
+
+3. **Add collapsible state:**
+```ts
+const [collapsed, setCollapsed] = useState<Set<string>>(new Set());
+const toggleGroup = (slug: string) => {
+  setCollapsed(prev => {
+    const next = new Set(prev);
+    next.has(slug) ? next.delete(slug) : next.add(slug);
+    return next;
+  });
+};
+```
+
+4. **Render structure:**
+```
+Header (Sessions + New Chat button + Create Group button)
+├─ Ungrouped sessions (flat list)
+├─ Group 1 header (collapsible, with count badge)
+│  └─ Group 1 sessions (hidden if collapsed)
+├─ Group 2 header
+│  └─ Group 2 sessions
+└─ ...
+```
+
+5. **Group header component:**
+```tsx
+<div className="flex items-center gap-2 px-3 py-2 cursor-pointer" onClick={() => toggleGroup(slug)}>
+  <ChevronRight className={`h-4 w-4 transition-transform ${!collapsed.has(slug) ? 'rotate-90' : ''}`} />
+  <Folder className="h-4 w-4 text-duck-teal" />
+  <span className="font-medium">{group.name}</span>
+  <span className="text-xs text-duck-dark/40">({group.sessionCount})</span>
+</div>
+```
+
+6. **Session item:** Add group indicator badge if grouped
+
+---
+
+## Phase 8.2: Group Management UI
+
+### 8.2.1: Create Group Dialog
+
+**File:** New component `src/apps/officer-web/Screens/Dashboard/ChatHistory/CreateGroupDialog.tsx`
+
+**Trigger:** Button in SessionList header (next to "New Chat")
+
+**Fields:**
+- Name (required) — auto-generates slug
+- Description (optional)
+
+**Slug generation:**
+```ts
+const toSlug = (name: string) => name.toLowerCase().replace(/[^a-z0-9]+/g, '-').replace(/^-|-$/g, '');
+```
+
+**On submit:** Call `createGroup(name, slug, description)`
+
+### 8.2.2: Group Context Menu
+
+**File:** Update `Screen.tsx`
+
+**On group header right-click or "..." button:**
+- Rename group → inline edit or dialog
+- Delete group → confirmation dialog ("Sessions will be ungrouped")
+
+### 8.2.3: Session Context Menu
+
+**File:** Update `Screen.tsx`
+
+**On session right-click or "..." button:**
+- Move to group → submenu with group list + "Ungrouped"
+- Rename session (existing)
+- Delete session (existing)
+
+**Implementation:** Use `moveSession(sessionId, groupSlug)` from `useChatGroups`
+
+---
+
+## Phase 8.3: Widget Updates (Optional)
+
+**File:** `src/apps/officer-web/Screens/Dashboard/ChatHistory/Widget.tsx`
+
+Simpler version — just show recent sessions, no grouping. Or:
+- Show 3 most recent ungrouped
+- Show group names with expand link to full view
+
+**Decision:** Keep Widget simple for now, grouping only in full SessionList.
+
+---
+
+## Implementation Order
+
+1. **8.1.1** — Add `useChatGroups` import and group sessions by slug
+2. **8.1.2** — Add collapsible state and group headers
+3. **8.1.3** — Style group headers with icons and counts
+4. **8.2.1** — Create Group dialog
+5. **8.2.2** — Group context menu (rename/delete)
+6. **8.2.3** — Session context menu (move to group)
+
+---
+
+## Files to Create/Modify
+
+| File | Action |
+|------|--------|
+| `ChatHistory/Screen.tsx` | Major update — grouping logic, collapsible UI, context menus |
+| `ChatHistory/CreateGroupDialog.tsx` | New — create group form |
+| `ChatHistory/GroupContextMenu.tsx` | New — rename/delete group actions |
+| `ChatHistory/SessionContextMenu.tsx` | New — move/rename/delete session actions |
+
+---
+
+## Testing Checklist
+
+- [ ] Sessions without groupSlug appear in "Ungrouped" section
+- [ ] Sessions with groupSlug appear under correct group
+- [ ] Groups are collapsible (click header to toggle)
+- [ ] Group session counts are accurate
+- [ ] Create group dialog opens and creates group
+- [ ] Slug is auto-generated from name
+- [ ] Rename group works (inline or dialog)
+- [ ] Delete group moves sessions to ungrouped
+- [ ] Move session to group works
+- [ ] Move session to ungrouped works
+- [ ] UI updates immediately after all operations
+
+---
+
+## Estimated Effort
+
+- **8.1 (Grouped UI):** ~1-2 hours
+- **8.2 (Group Management):** ~2-3 hours
+- **8.3 (Widget):** Skip for now
+
+**Total:** ~3-5 hours
