+Đầy đủ tất cả modules, bao gồm:
+- Feedback, Customer, Product, Contract, FeedbackChannel, FeedbackTag
+- User, Role (admin-only)
+- 3 Dashboard widgets: ResolvedTicketsWidget, AvgProcessingTimeWidget, HandlerPerformanceWidget
+
+### Support Panel (`/support`) — `SupportPanelProvider.php`

+- Feedback, Customer, Product, FeedbackChannel, FeedbackTag, ActivityLog
+- 3 Dashboard widgets giống Admin panel
+- Không có: Contracts, Users, Roles, Handovers, ProductServices
+
+Cả 2 panel dùng chung: Models, Services, Policies, Database, Translations.

 20. **Tailwind CSS in Filament**: Custom blade views render inside Filament layout which does NOT include full Tailwind CSS build. Must add needed utilities to `public/css/filament-custom.css` with `!important`.
 21. **SVG icon sizing**: Use inline `width`/`height` attributes on SVG icons (e.g., `<svg width="14" height="14">`) instead of Tailwind classes (`w-3.5 h-3.5`) — prevents Filament CSS from overriding sizes.

 ## Services — Tóm tắt
 
+### ActivityLogger (`app/Services/ActivityLogger.php`) — NEW
+- `ActivityLogger::log(action, description, subject?, metadata?, userId?)`: Static method. Tạo ActivityLog record cho audit trail. Dùng trong Import/Export/Transfer/Close/Create/Update/Delete.
+
 ### TransferService (`app/Services/TransferService.php`)
 - `transfer(Feedback, Department, reason, User, ?int $newHandlerId)`: Tạo TicketTransferLog, cập nhật current_department_id + assigned_to, gửi TicketTransferred notification cho manager đích.
 - Validate reason không được rỗng (ValidationException).
 
+### FileService (`app/Services/FileService.php`)
+- `upload()`: Validate (jpg/png/pdf/mp4/mov, ≤20MB), store vào public disk, tạo FeedbackAttachment record.
+- `getTemporaryUrl()` / `getPreviewUrl()`: Signed URL cho private file.
+- `getByCollection()` / `hasCollection()`: Query collection-based attachments.
+
 ### ClosingService (`app/Services/ClosingService.php`)
 - `close(Feedback, User)`: 4 guard: status ≠ closed, staff → 403, manager chỉ đóng ticket phòng mình, phải có proof_of_resolution attachment (FileService::hasCollection). Gửi TicketClosed notification.
 - `resolve(Feedback, User)`: Đánh dấu resolved (không role gate).
 
-### FileService (`app/Services/FileService.php`)
-- `upload()`: Validate (jpg/png/pdf/mp4/mov, ≤20MB), store vào private local disk (`feedback-attachments/`), tạo FeedbackAttachment record.
-- `getTemporaryUrl()` / `getPreviewUrl()`: Signed URL cho private file.
-- `getByCollection()` / `hasCollection()`: Query collection-based attachments.

+- [x] SVG icons: Use inline `width`/`height` attributes instead of Tailwind classes
+- [x] GlobalSearch: Customized for all Resources with multi-field search
+- [x] RelationManager titles: Override `getTitle()` for proper translation
+- [x] Enum refactoring: Added `color()` method, static `options()`, developer comments
+- [x] Documentation: Created `docs/I18N_GUIDE.md` and `docs/ENUM_GUIDE.md`
+
+### Support Panel (Dual Panel)
+- [x] `SupportPanelProvider`: panel thứ 2 tại path `/support`, rút gọn chỉ tập trung feedback
+- [x] Resources trong Support: Feedback, Customer, Product, FeedbackChannel, FeedbackTag, ActivityLog
+- [x] Widgets: ResolvedTicketsWidget, AvgProcessingTimeWidget, HandlerPerformanceWidget
+
+### ActivityLog — Audit Trail
+- [x] Migration `activity_logs`: user_id, action, description, subject_type/id, metadata
+- [x] Model `ActivityLog` + Service `ActivityLogger` (static log method)
+- [x] Filament Resource `ActivityLogResource` (read-only, list view with filters)

-- [x] Cập nhật Model `Feedback`: fillable + relationship `contract()`
-- [x] Logic auto-select active contract khi tạo Feedback mới (FeedbackForm)
-- [x] Hiển thị contract info trên Feedback list (FeedbackTable column)
-- [x] Gán contract_id cho feedback mẫu trong Seeder
-
-### C: Module Bàn giao (Handover) — từ `AI_01`, `AI_02`
-- [x] Tạo migration bảng `handovers`:
-  - `product_id` FK, `customer_id` FK
-  - `handover_date` (date)
-  - `status` (Chưa đủ điều kiện/Đủ ĐK/Đã lên lịch/Đã BG)
-  - `remark` (text nullable)
-- [x] Tạo Model `Handover` + Enum `HandoverStatus`
-- [x] Relationships: `product()`, `customer()`
-- [x] Tạo `HandoversRelationManager` gắn vào `ProductResource`
-- [x] Cập nhật Product model: thêm `handovers()` HasMany
-
-### D: Module Dịch vụ phụ trợ (ProductService) — từ `AI_02`
-- [x] Tạo migration bảng `product_services`:
-  - `product_id` FK
-  - `service_type` (MANAGEMENT_FEE/GRATITUDE/SELF_BUSINESS)
-  - `status`
-  - `actual_collection_date` (date nullable)
-  - `remark` (text nullable)
-- [x] Tạo Model `ProductService` + Enum `ServiceType`
-- [x] Relationship: `product()`
-- [x] Tạo `ProductServicesRelationManager` gắn vào `ProductResource`
-- [x] Cập nhật Product model: thêm `productServices()` HasMany
-
-### E: Enhancement ProductResource — từ `AI_02`
-- [x] Thêm RelationManagers vào `ProductResource::getRelations()`
-  - ContractsRelationManager ✅
-  - HandoversRelationManager ✅
-  - ProductServicesRelationManager ✅
-- [x] Product detail page có 3 tabs: Contracts + Handovers + Services
-
-### F: Tự động gợi ý transfer — từ `AI_01` (optional)
 - [ ] Hiển thị badge gợi ý: "Ticket BCC → khuyến nghị chuyển Pháp lý"
 - [ ] Logic detect contract type → suggest department
 
-### G: Data Import Pipeline — từ `AI_03`
-- [x] Cài package `spatie/simple-excel`
-- [x] Tạo Command `app:import-cskh {file_path} --dry-run`
-- [x] Logic: Lazy Collection, chunk 100 rows, DB::transaction, ProgressBar
-- [x] Pipeline per row: Product/Customer firstOrCreate → Contract/Handover/Service → Feedback + Interactions
-- [x] Tạo customer_product pivot record
-- [x] Xử lý DateTimeImmutable từ Excel
-- [x] Skip header/meta rows
-- [x] Đã test thành công với CSKH.xlsx (3658 rows → 3299 products, 2089 customers, 2637 contracts, 2077 handovers, 159 services, 71 feedbacks, 226 interactions)
