+# Admin Purchase Notifications Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Notify admin (toast + topbar bell badge/panel) when a new order lands on the marketplace, poll-based since the backend has no WebSocket/SSE.
+
+**Architecture:** A single `AdminOrderWatcherService` polls `AdminOrdersLocalGateway.loadOrders()` on an editable interval (default 15s), diffs against a persisted "last notified" order id to fire toasts for genuinely new orders, and exposes a `recentOrders`/`unreadCount` signal pair that the existing (currently-empty) topbar bell panel renders. Poll interval is editable in the admin settings page, same pattern as the currency-rates section added previously.
+
+**Tech Stack:** Angular 17+ signals, RxJS, Jasmine/Karma (`ng test`), existing `LocalStorageService`/`UserNotificationService`/`TranslateService` patterns.
+
+## Global Constraints
+
+- No WebSocket/SSE available — polling only (confirmed `BACKEND-API-REFERENCE.md:20`).
+- Persist state via `LocalStorageService` (`getItem`/`setItem`), never raw `localStorage`.
+- Reuse the existing topbar bell (`admin-layout.component.html:141-157`) instead of adding a new nav badge.
+- Admin backoffice price/amount displays stay in the order's raw stored currency (no `currencyConvert` pipe) — consistent with every other admin screen.
+- Route arrays for admin navigation use the pattern `[languageService.currentLanguage(), 'backoffice', 'orders', id]` (no leading `/`), matching `admin-orders-list-page.component.ts:52`.
+
+---
+
+### Task 1: `UserNotificationService` gains an optional click-to-navigate route
+
+**Files:**
+- Modify: `src/app/features/website/user-experience/services/user-notification.service.ts`
+- Modify: `src/app/features/website/user-experience/components/floating-notifications/floating-notifications.component.ts`
+- Modify: `src/app/features/website/user-experience/components/floating-notifications/floating-notifications.component.html`
+- Test: `src/app/features/website/user-experience/services/user-notification.service.spec.ts` (new)
+
+**Interfaces:**
+- Produces: `UserNotificationService.show(message: string, type?: UserNotificationType, durationMs?: number, route?: string[]): void`
+- Produces: `UserNotification.route?: string[]`
+
+- [ ] **Step 1: Write the failing test**
+
+Create `src/app/features/website/user-experience/services/user-notification.service.spec.ts`:
+
+```typescript
+import { TestBed } from '@angular/core/testing';
+import { UserNotificationService } from './user-notification.service';
+
+describe('UserNotificationService', () => {
+  let service: UserNotificationService;
+
+  beforeEach(() => {
+    TestBed.configureTestingModule({});
+    service = TestBed.inject(UserNotificationService);
+  });
+
+  it('stores the route on the notification when provided', () => {
+    service.show('New order #1042', 'info', 4000, ['en', 'backoffice', 'orders', 'ord_1']);
+
+    const [note] = service.notifications();
+    expect(note.message).toBe('New order #1042');
+    expect(note.route).toEqual(['en', 'backoffice', 'orders', 'ord_1']);
+  });
+
+  it('leaves route undefined when not provided', () => {
+    service.show('Saved');
+
+    const [note] = service.notifications();
+    expect(note.route).toBeUndefined();
+  });
+});
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `npm run test -- --include='**/user-notification.service.spec.ts'`
+Expected: FAIL — `show` has no fourth parameter, `route` does not exist on `UserNotification`.
+
+- [ ] **Step 3: Implement**
+
+Replace the full contents of `src/app/features/website/user-experience/services/user-notification.service.ts`:
+
+```typescript
+import { Injectable, signal } from '@angular/core';
+
+export type UserNotificationType = 'success' | 'info' | 'warning';
+
+export interface UserNotification {
+  id: string;
+  message: string;
+  type: UserNotificationType;
+  /** Route to navigate to when the notification is clicked. Absent means not clickable. */
+  route?: string[];
+}
+
+@Injectable({ providedIn: 'root' })
+export class UserNotificationService {
+  private readonly state = signal<UserNotification[]>([]);
+
+  readonly notifications = this.state.asReadonly();
+
+  show(message: string, type: UserNotificationType = 'info', durationMs: number = 2500, route?: string[]): void {
+    const next: UserNotification = {
+      id: `note-${Date.now()}-${Math.random().toString(36).slice(2, 8)}`,
+      message,
+      type,
+      ...(route ? { route } : {}),
+    };
+
+    this.state.update(items => [next, ...items].slice(0, 4));
+
+    setTimeout(() => this.dismiss(next.id), durationMs);
+  }
+
+  dismiss(id: string): void {
+    this.state.update(items => items.filter(item => item.id !== id));
+  }
+}
+```
+
+Modify `src/app/features/website/user-experience/components/floating-notifications/floating-notifications.component.ts` — replace full contents:
+
+```typescript
+import { ChangeDetectionStrategy, Component, inject } from '@angular/core';
+import { Router } from '@angular/router';
+import { UserNotification, UserNotificationService } from '../../services/user-notification.service';
+import { TranslatePipe } from '../../../../../i18n/translate.pipe';
+
+@Component({
+  selector: 'app-floating-notifications',
+  standalone: true,
+  imports: [TranslatePipe],
+  templateUrl: './floating-notifications.component.html',
+  styleUrls: ['./floating-notifications.component.scss'],
+  changeDetection: ChangeDetectionStrategy.OnPush
+})
+export class FloatingNotificationsComponent {
+  private readonly notificationsService = inject(UserNotificationService);
+  private readonly router = inject(Router);
+
+  readonly notifications = this.notificationsService.notifications;
+
+  dismiss(id: string): void {
+    this.notificationsService.dismiss(id);
+  }
+
+  navigate(note: UserNotification): void {
+    if (note.route) {
+      void this.router.navigate(note.route);
+    }
+    this.dismiss(note.id);
+  }
+}
+```
+
+Replace full contents of `src/app/features/website/user-experience/components/floating-notifications/floating-notifications.component.html`:
+
+```html
+@if (notifications().length > 0) {
+  <aside class="floating-notifications" aria-live="polite" aria-atomic="true">
+    @for (note of notifications(); track note.id) {
+      <article
+        class="floating-note"
+        [class]="'floating-note floating-note-' + note.type"
+        [class.floating-note-clickable]="!!note.route"

+      </article>
+    }
+  </aside>
+}
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `npm run test -- --include='**/user-notification.service.spec.ts'`
+Expected: PASS (2 specs)
+
+- [ ] **Step 5: Commit**
+
+```bash

+
+### Task 2: `AdminOrderWatcherService` — polling, diffing, toast firing
+
+**Files:**
+- Create: `src/app/features/admin/shell/services/admin-order-watcher.service.ts`
+- Test: `src/app/features/admin/shell/services/admin-order-watcher.service.spec.ts`
+- Modify: `src/app/i18n/translations.ts`, `src/app/i18n/en.ts`, `src/app/i18n/ru.ts`, `src/app/i18n/hy.ts` (one new key)
+
+**Interfaces:**
+- Consumes: `AdminOrdersLocalGateway.loadOrders(filters: AdminOrderListFilters): Observable<AdminOrdersListResult>` (existing)
+- Consumes: `UserNotificationService.show(message, type?, durationMs?, route?)` (Task 1)
+- Consumes: `LocalStorageService.getItem(key): string | null`, `.setItem(key, value): void` (existing)
+- Produces: `AdminOrderWatcherService.recentOrders: Signal<AdminOrder[]>`
+- Produces: `AdminOrderWatcherService.unreadCount: Signal<number>`
+- Produces: `AdminOrderWatcherService.intervalMs: Signal<number>`
+- Produces: `AdminOrderWatcherService.start(): void`
+- Produces: `AdminOrderWatcherService.markAllSeen(): void`
+- Produces: `AdminOrderWatcherService.setIntervalSeconds(seconds: number): void`
+
+- [ ] **Step 1: Add the i18n key first (needed by the test's translated toast message)**
+
+In `src/app/i18n/translations.ts`, inside the `topbar:` block under `adminShell` (next to `notificationsEmpty: string;`):
+
+```typescript
+      notificationsEmpty: string;
+      notificationNewOrder: string;
+```
+
+In `src/app/i18n/en.ts`, inside `adminShell.topbar` (next to `notificationsEmpty:`):
+
+```typescript
+      notificationsEmpty: 'No new notifications',
+      notificationNewOrder: 'New order #{{orderNumber}}',
+```
+
+In `src/app/i18n/ru.ts`, inside `adminShell.topbar`:
+
+```typescript
+      notificationsEmpty: 'Нет новых уведомлений',
+      notificationNewOrder: 'Новый заказ №{{orderNumber}}',
+```
+
+In `src/app/i18n/hy.ts`, inside `adminShell.topbar`:
+
+```typescript
+      notificationsEmpty: 'Նոր ծանուցումներ չկան',
+      notificationNewOrder: 'Նոր պատվեր #{{orderNumber}}',
+```
+
+(Match each file's existing `notificationsEmpty` value/indentation exactly — only add the new line after it.)

+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `npm run test -- --include='**/admin-layout.component.spec.ts'`
+Expected: FAIL — `AdminOrderWatcherService` not referenced by the component yet, `unreadCount`/`recentOrders` don't exist on `AdminLayoutComponent`.
+
+- [ ] **Step 3: Implement**
+
+In `src/app/features/admin/shell/admin-layout.component.ts`, add the import and field (place near the other service injections):
+
+```typescript
+import { AdminOrderWatcherService } from './services/admin-order-watcher.service';
+```
+
+```typescript
+  private readonly orderWatcher = inject(AdminOrderWatcherService);
+
+  readonly unreadCount = this.orderWatcher.unreadCount;
+  readonly recentOrders = this.orderWatcher.recentOrders;
+```
+
+In the constructor, after `this.readRouteData();`, add:
+
+```typescript
+    this.orderWatcher.start();
+```
+
+Replace the `toggleNotifications` method:
+
+```typescript
+  toggleNotifications(): void {
+    this.notificationsOpen.update(open => !open);
+    if (this.notificationsOpen()) {
+      this.orderWatcher.markAllSeen();
+    }
+  }
+```
+
+Add a navigation helper next to `adminLinkFor`:
+
+```typescript
+  goToOrder(orderId: string): void {
+    void this.router.navigate([this.currentLang(), 'backoffice', 'orders', orderId]);
+    this.notificationsOpen.set(false);
+  }
+```
+
+In `src/app/features/admin/shell/admin-layout.component.html`, replace the notifications block (lines 141-157):
+
+```html
+      <div class="admin-layout__notifications">
+        <button
+          type="button"
+          class="admin-layout__icon-button"
+          aria-haspopup="true"
+          [attr.aria-expanded]="notificationsOpen()"

+          (click)="toggleNotifications()"
+        >

+          @if (unreadCount() > 0) {
+            <span class="admin-layout__notifications-badge">{{ unreadCount() }}</span>
+          }
+        </button>
+        @if (notificationsOpen()) {
+          <div class="admin-layout__notifications-panel" role="menu">

+            }
+          </div>
+        }
+      </div>
+```
+
+In `src/app/features/admin/shell/admin-layout.component.scss`, add (near other `.admin-layout__notifications*` rules if any exist, otherwise at the end):
+
+```scss

+
+- [ ] **Step 5: Run test to verify it passes**
+
+Run: `npm run test -- --include='**/admin-settings-page.component.spec.ts'`

+git commit -m "feat: editable new-order poll interval in admin settings"
+```
+
+---
+
+## Manual Verification (after all tasks)
+
+1. `npm run barry -- kb search --source cq --query "admin order notifications"` if KB sharing is enabled (skip if local-only — see project `CLAUDE.md`).
+2. Start the dev server, log into `/backoffice`, leave the tab open.
+3. In another tab (or via `admin-orders-local.gateway.ts`'s seed data timing), wait for the poll interval — confirm no toast fires on first load.
+4. Trigger a new order (checkout flow in `cart.component.ts`, or temporarily lower `SEED_COUNT`/seed timing in `admin-orders-local.gateway.ts` to simulate one — revert after testing) and confirm: toast appears with the order number, bell badge shows `1`, clicking either navigates to `/backoffice/orders/:id`.
+5. Open the bell panel without clicking a row — confirm badge clears but the order still lists in the panel.
+6. Change the interval in Admin Settings, save, confirm the toast "Interval saved" message. no crash on next poll cycle.

+# Admin purchase notifications — design
+
+**Status:** Approved
+**Date:** 2026-08-15
+**Related backlog item:** #7 (marked ВАЖНО — important)
+
+## Problem
+
+Admin has no signal when a purchase happens on the marketplace. Orders only surface if
+someone manually opens the Orders list and refreshes. Backend exposes no WebSocket/SSE
+(confirmed in `BACKEND-API-REFERENCE.md:20` — every "live" feature today, e.g. payment
+status, is plain polling), so this has to be poll-based like the rest of the app.
+
+## Architecture
+
+**`AdminOrderWatcherService`** (new, `providedIn: root`, admin-scoped)
+
+- Polls `AdminOrdersLocalGateway.loadOrders()` (sorted `createdAt` desc, already the
+  default sort) on an interval.
+- Diffs the newest order's `id`/`createdAt` against the last-seen value, kept in memory
+  and persisted via `LocalStorageService` (survives page reload, same pattern as
+  `AdminPreferencesService`).
+- On finding order(s) newer than last-seen: fires one toast per new order and
+  increments an `unreadCount` signal.
+- Started once at the admin shell root, so it keeps polling regardless of which admin
+  page is open.
+
+**Poll interval**
+
+- Editable by admin, default 15s.
+- Setting lives in the same admin-settings page as currency rates
+  (`admin-settings-page.component.ts`), persisted via `LocalStorageService`.
+
+**Toast delivery**
+
+- Reuses the existing `UserNotificationService` / `FloatingNotificationsComponent`
+  (already global — `providedIn: root`, mounted once in `app.html`). No new toast UI.
+- `UserNotification` gains an optional `route: string[]` field.
+- `FloatingNotificationsComponent` gets a click handler: navigate to `route` (if set)
+  then dismiss.
+
+**Badge — reuses existing topbar bell**
+
+`admin-layout.component.html:141-157` already has an unused bell icon +
+dropdown panel (currently hardcoded to always show "no notifications").
+Wire the watcher's data into it instead of adding a new indicator:
+
+- `unreadCount` signal (from `AdminOrderWatcherService`) rendered as a badge
+  on the bell icon (`admin-layout__icon-button`).
+- Opening the panel (`notificationsOpen()`, already wired to the bell click)
+  lists the unread new orders instead of the static "notificationsEmpty"
+  text.
+- Opening the panel marks all currently-known orders as seen → badge resets
+  to 0 (same trigger `AdminLayoutComponent.toggleNotifications()` already
+  has).
+
+**Click behavior**
+
+- Toast click → `/admin/orders/:id` (the new order's detail page).
+- Clicking an order row inside the bell panel → same, then closes the panel.
+
+## Data flow
+
+```
+AdminOrderWatcherService (interval timer)
+  -> AdminOrdersLocalGateway.loadOrders()
+  -> diff against last-seen order id/createdAt (LocalStorageService)
+  -> new order(s) found?
+       -> UserNotificationService.show(message, 'info', { route: ['/admin/orders', id] })
+       -> unreadCount.update(n => n + 1)
+  -> admin clicks toast/badge -> router navigate -> orders-list visit resets unreadCount
+```
+
+## Error handling
+
+Poll failures are silent/logged only (`console.error`), consistent with existing
+polling code (payment status polling in `cart.component.ts`). No toast spam on
+transient network errors — watcher just retries on the next interval.
+
+## Out of scope
+
+- Native OS push notifications (tab not focused) — user explicitly chose in-app
+  toast/badge only, not browser Notification API.
+- Sound alerts — not selected.
+- Telegram/email alerts to staff — not selected, would need backend bot/mail
+  integration.
