Subject: [PATCH] feat(ui): Contact Management v2 - existing contacts display
 and delete
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements MVP v2 requirements from docs/UI-Contact-Management-MVP-v2.md:
- Display all contact types (CLI, REP, ROOM, SENS)
- Delete contacts with confirmation modal
- Capacity counter with color-coded warnings (green/yellow/red)
- Search by name or public key
- Filter by contact type
- Mobile-first responsive design

Backend changes:
- Add get_all_contacts_detailed() parser for meshcli contacts output
  - Handles Unicode characters, emoji, spaces in names
  - Backward parsing strategy using public_key_prefix as anchor
  - Returns detailed metadata for all contact types
- Add delete_contact() wrapper for remove_contact command
- Add GET /api/contacts/detailed endpoint
- Add POST /api/contacts/delete endpoint

Frontend changes:
- Add Existing Contacts section to contacts.html
  - Real-time search input
  - Type filter dropdown (All/CLI/REP/ROOM/SENS)
  - Color-coded type badges
  - Capacity counter with pulse animation for critical levels
- Add delete confirmation modal with danger styling
- Add complete contact management logic to contacts.js
  - loadExistingContacts(), applyFilters(), confirmDelete()
  - Copy public key to clipboard functionality

Documentation:
- Update README.md with usage instructions
- Add technotes/UI-Contact-Management-MVP-v2-completed.md
- Add docs/UI-Contact-Management-MVP-v2.md (specification)
- Add technotes/UI-Contact-Management-MVP-v1-completed.md (retroactive)

Tested with 263 real contacts including Unicode and edge cases.

+#### Existing Contacts
+
+The Existing Contacts section displays all contacts currently stored on your device (CLI, REP, ROOM, SENS types).
+
+**Features:**
+- **Counter badge** - Shows current contact count vs. 350 limit (MeshCore device max)
+  - Green: Normal (< 300 contacts)
+  - Yellow: Warning (300-339 contacts)
+  - Red (pulsing): Alarm (≥ 340 contacts)
+- **Search** - Filter contacts by name or public key prefix
+- **Type filter** - Show only specific contact types (All / CLI / REP / ROOM / SENS)
+- **Contact cards** - Display name, type badge, public key prefix, and path info
+
+**Managing contacts:**
+1. **Search contacts:**
+   - Type in the search box to filter by name or public key prefix
+   - Results update instantly as you type
+
+2. **Filter by type:**
+   - Use the type dropdown to show only:
+     - **CLI** - Client devices (blue badge)
+     - **REP** - Repeaters (green badge)
+     - **ROOM** - Room servers (cyan badge)
+     - **SENS** - Sensors (yellow badge)
+
+3. **Copy public key:**
+   - Click "Copy Key" button to copy the public key prefix to clipboard
+   - Useful for sharing or verification
+
+4. **Delete a contact:**
+   - Click the "Delete" button (red trash icon)
+   - Confirm deletion in the modal dialog
+   - Contact is permanently removed from device
+   - **Warning:** This action cannot be undone
+
+**Refresh contacts list:**
+- Click the "Refresh" button to reload the contacts list
+- The page automatically loads contacts when first opened
+
+**Monitoring contact capacity:**
+- MeshCore devices have a limit of 350 contacts
+- The counter badge changes color as you approach the limit:
+  - **0-299**: Green (plenty of space)
+  - **300-339**: Yellow warning (nearing limit)
+  - **340-350**: Red alarm (critical - delete some contacts soon)
+

+## Prompt dla Claude Code: Contact Management v2 (Existing Contacts + Delete + Counter)
+
+Pracujesz w repo `mc-webui`. Mamy już działający moduł UI **Contact Management (MVP v1)**: toggle `manual_add_contacts` + lista `pending_contacts` + approve. Teraz robimy etap v2: zarządzanie istniejącymi kontaktami.
+
+### Cel (v2)
+
+Rozbuduj moduł **Contact Management** o:
+
+1. Panel **Existing Contacts**
+
+   * wyświetla listę kontaktów, które są już na urządzeniu (CLI/REP/ROOM — wszystkie)
+   * umożliwia **usuwanie** wybranego kontaktu
+   * pokazuje licznik kontaktów `X / 350` (limit MeshCore)
+   * ma podstawowe filtrowanie i wyszukiwanie (lekko, bez frameworków)
+
+2. UX:
+
+   * mobile-first (przyciski dotykowe, brak gęstych tabel)
+   * szybkie odświeżanie listy, spinner/placeholder
+   * potwierdzenie usunięcia (modal lub confirm), bo to operacja destrukcyjna
+
+### Wymagania techniczne / integracja
+
+* Frontend: Flask templates + Bootstrap5 + vanilla JS. 
+* Backend: mc-webui komunikuje się z meshcore-bridge przez HTTP (nie przez lokalny meshcli). 
+* Mamy już wzorzec: mc-webui ma endpointy `/api/...` i JS robi fetch do mc-webui, a mc-webui proxy’uje do bridge.
+
+### Dane i API
+
+1. **Pobranie listy kontaktów**
+
+   * Dodaj w mc-webui endpoint:
+
+     * `GET /api/contacts/list`
+   * On powinien pobierać listę kontaktów z bridge’a przez mechanizm CLI:
+
+     * albo istniejący endpoint w mc-webui (jeśli jest), który wykonuje `meshcli contacts` i zwraca JSON,
+     * albo dodaj nowy “proxy” do `/cli` z komendą `contacts` i następnie sparsuj output.
+   * Zależy mi na JSON po stronie mc-webui w formacie:
+
+     ```json
+     {
+       "success": true,
+       "count": 123,
+       "limit": 350,
+       "contacts": [
+         {
+           "name": "BBKr",
+           "public_key_prefix": "efa30de66fce",
+           "type_label": "CLI|REP|ROOM|UNKNOWN",
+           "path_or_mode": "Flood|<path_hex>|",
+           "raw_line": "..."
+         }
+       ]
+     }
+     ```
+   * Parser:
+
+     * ma być odporny na emoji i spacje w nazwach
+     * nie zakładaj stałej liczby spacji — użyj regex / split z głową
+     * `raw_line` zachowaj do debugowania
+
+2. **Usuwanie kontaktu**
+
+   * Dodaj w mc-webui endpoint:
+
+     * `POST /api/contacts/delete` body: `{ "name": "...", "public_key_prefix": "..." }`
+   * Na backendzie wywołaj komendę meshcli, która usuwa kontakt.
+
+     * Najpierw sprawdź w `meshcli -h` / dokumentacji projektu jak brzmi komenda (np. `del_contact` / `rm_contact` / `remove_contact` / `contact_del` — NIE zakładaj nazwy).
+     * Jeśli usuwanie po nazwie jest niepewne (kolizje), użyj najbezpieczniejszego selektora dostępnego w CLI (prefiks klucza jeśli wspierany).
+   * Po sukcesie: zwróć `{success:true}` i na froncie odśwież listę.
+
+3. **Licznik 350**
+
+   * `count = len(contacts)` po parsowaniu.
+   * `limit = 350` stała w UI (do ewentualnej zmiany później).
+   * UI ma pokazywać badge:
+
+     * OK: zielony/neutralny
+     * ostrzegawczy gdy `count >= 300`
+     * alarm gdy `count >= 340`
+       (prosta logika, bez przesady)
+
+### UI: Contact Management v2
+
+W istniejącym widoku `Contact Management` dodaj pod sekcją pending nową sekcję:
+
+**Existing Contacts**
+
+* Toolbar:
+
+  * Search input (client-side filter po `name` i `public_key_prefix`)
+  * Filter dropdown: All / CLI / REP / ROOM / Unknown
+  * Refresh button
+* Lista (list-group/cards):
+
+  * name (bold)
+  * type_label badge (CLI/REP/ROOM)
+  * public_key_prefix + copy
+  * optional: “path_or_mode” (jeśli masz z outputu)
+  * Delete button (danger, ikonka kosza)
+* Delete flow:
+
+  * confirm (Bootstrap modal albo `confirm()`; prefer modal)
+  * po delete: toast + refresh
+
+### Ograniczenia / bezpieczeństwo
+
+* Nie zmieniaj bridge’a jeśli nie musisz. Preferuj: mc-webui proxy do istniejącego `/cli` w bridge.
+* Nie dodawaj WebSocketów. Refresh ręczny wystarczy.
+* Wszystkie komentarze i nazwy w kodzie: po angielsku.
+
+### Test plan
+
+Dodaj do README sekcję “Contact Management v2”:
+
+* jak odświeżyć listę kontaktów
+* jak filtrować
+* jak usunąć kontakt
+* jak sprawdzić w logach, że komenda delete poszła do bridge
+
+### Post-task checklist
+
+1. Update README.md
+2. Jeśli projekt ma plik notatek/technotes, dopisz krótką notkę o parsowaniu outputu `contacts`
+3. Conventional commit: `feat: contact management v2 (existing contacts + delete + counter)`
+
+---
+
+### Drobna wskazówka
+
+Output `meshcli contacts` wygląda zwykle jak tabela (kolumny: name / type / pubkey_prefix / path lub “Flood”). Parser ma być “best effort”: nie musisz perfekcyjnie odtwarzać wszystkich pól, ale **name + pubkey_prefix + type** muszą być wiarygodne.

+# Contact Management MVP v1 - Implementation Complete
+
+**Date**: 2025-12-29
+**Status**: ✅ Completed and Tested
+**Branch**: `dev-2`
+**Commit**: `77c72ba`
+
+## Overview
+
+Successfully implemented Contact Management MVP v1, a complete UI module for managing manual contact approval in mc-webui. The implementation provides persistent, user-controlled settings that survive container restarts, replacing the previous testing-only forced configuration.
+
+## Requirements
+
+Based on specification in `docs/UI-Contact-Management-MVP-v1.md`:
+
+### Functional Requirements
+1. **Manual Approval Toggle**
+   - Persistent across container restarts
+   - Default: OFF (automatic approval - meshcli factory default)
+   - User decision becomes source of truth
+
+2. **Pending Contacts Management**
+   - List pending contacts awaiting approval
+   - Show name and truncated public key
+   - Approve action (must use full public_key)
+   - Copy full public key to clipboard
+
+3. **Mobile-First UI**
+   - Touch-friendly buttons (min-height: 44px)
+   - Responsive card layout
+   - Bootstrap 5 components
+   - Toast notifications for user feedback
+
+4. **Integration**
+   - Menu item in side navigation
+   - Route: `/contacts/manage`
+   - Consistent with existing UI patterns
+
+### Non-Functional Requirements
+- Settings must persist across container restarts
+- Settings file stored in volume-mounted MC_CONFIG_DIR
+- Backward compatible (defaults to meshcli factory settings)
+- Real-time feedback (loading states, error handling)
+
+## Architecture
+
+### Settings Persistence Mechanism
+
+**File-based persistence** via `.webui_settings.json`:
+
+```
+MC_CONFIG_DIR/
+├── .webui_settings.json  ← Persistent settings (NEW)
+├── MeshCore.msgs
+└── MeshCore.db
+```
+
+**Settings file format**:
+```json
+{
+  "manual_add_contacts": true
+}
+```
+
+**Persistence flow**:
+
+```

+
+## Implementation Details
+
+### 1. Backend - meshcore-bridge (bridge.py)
+
+**Added**: Settings persistence mechanism
+
+```python
+def _load_webui_settings(self) -> dict:
+    """Load webui settings from .webui_settings.json file"""
+    settings_path = self.config_dir / ".webui_settings.json"
+
+    if not settings_path.exists():
+        logger.info("No webui settings file found, using defaults")
+        return {}
+
+    try:
+        with open(settings_path, 'r', encoding='utf-8') as f:
+            settings = json.load(f)
+            logger.info(f"Loaded webui settings: {settings}")
+            return settings
+    except Exception as e:
+        logger.error(f"Failed to load webui settings: {e}")
+        return {}
+```
+
+**Modified**: Session initialization to read settings
+
+```python
+def _init_session_settings(self):
+    """Configure meshcli session for advert logging, message subscription, and user-configured settings"""
+    logger.info("Configuring meshcli session settings")
+
+    if self.process and self.process.stdin:
+        try:
+            # Core settings (always enabled)
+            self.process.stdin.write('set json_log_rx on\n')
+            self.process.stdin.write('set print_adverts on\n')
+            self.process.stdin.write('msgs_subscribe\n')
+
+            # User-configurable settings from .webui_settings.json
+            webui_settings = self._load_webui_settings()
+            manual_add_contacts = webui_settings.get('manual_add_contacts', False)
+
+            if manual_add_contacts:
+                self.process.stdin.write('set manual_add_contacts on\n')
+                logger.info("Session settings applied: json_log_rx=on, print_adverts=on, manual_add_contacts=on, msgs_subscribe")
+            else:
+                logger.info("Session settings applied: json_log_rx=on, print_adverts=on, manual_add_contacts=off (default), msgs_subscribe")
+
+            self.process.stdin.flush()
+        except Exception as e:
+            logger.error(f"Failed to apply session settings: {e}")
+```
+
+**Added**: New endpoint for settings update
+
+```python
+@app.route('/set_manual_add_contacts', methods=['POST'])
+def set_manual_add_contacts():
+    """
+    Enable or disable manual contact approval mode.
+
+    This setting is:
+    1. Saved to .webui_settings.json for persistence across container restarts
+    2. Applied immediately to the running meshcli session
+
+    Request JSON:
+        {"enabled": true/false}
+
+    Response:
+        {"success": true, "message": "...", "enabled": true/false}
+    """
+    try:
+        data = request.get_json()
+
+        if not data or 'enabled' not in data:
+            return jsonify({'success': False, 'error': 'Missing required field: enabled'}), 400
+
+        enabled = data['enabled']
+
+        if not isinstance(enabled, bool):
+            return jsonify({'success': False, 'error': 'enabled must be a boolean'}), 400
+
+        # Save to persistent settings file
+        settings_path = meshcli_session.config_dir / ".webui_settings.json"
+
+        try:
+            if settings_path.exists():
+                with open(settings_path, 'r', encoding='utf-8') as f:
+                    settings = json.load(f)
+            else:
+                settings = {}
+
+            settings['manual_add_contacts'] = enabled
+
+            with open(settings_path, 'w', encoding='utf-8') as f:
+                json.dump(settings, f, indent=2, ensure_ascii=False)
+
+            logger.info(f"Saved manual_add_contacts={enabled} to {settings_path}")
+        except Exception as e:
+            logger.error(f"Failed to save settings file: {e}")
+            return jsonify({'success': False, 'error': f'Failed to save settings: {str(e)}'}), 500
+
+        # Apply setting immediately to running session
+        command_value = 'on' if enabled else 'off'
+        result = meshcli_session.execute_command(['set', 'manual_add_contacts', command_value], timeout=DEFAULT_TIMEOUT)
+
+        if not result['success']:
+            return jsonify({'success': False, 'error': f"Failed to apply setting: {result.get('stderr', 'Unknown error')}"}), 500
+
+        return jsonify({'success': True, 'message': f"manual_add_contacts set to {command_value}", 'enabled': enabled}), 200
+
+    except Exception as e:
+        logger.error(f"API error in /set_manual_add_contacts: {e}")
+        return jsonify({'success': False, 'error': str(e)}), 500
+```
+
+### 2. Backend - mc-webui CLI Wrapper (cli.py)
+
+**Added**: Four new functions for contact management
+
+```python
+def get_pending_contacts() -> Tuple[bool, List[Dict], str]:
+    """Get list of contacts awaiting manual approval"""
+    # Proxies to bridge GET /pending_contacts
+
+def approve_pending_contact(public_key: str) -> Tuple[bool, str]:
+    """Approve and add a pending contact by public key"""
+    # Proxies to bridge POST /add_pending
+    # IMPORTANT: Always uses full public_key for compatibility
+
+def get_device_settings() -> Tuple[bool, Dict]:
+    """Get persistent device settings from .webui_settings.json"""
+    # Reads file directly from MC_CONFIG_DIR
+
+def set_manual_add_contacts(enabled: bool) -> Tuple[bool, str]:
+    """Enable or disable manual contact approval mode"""
+    # Proxies to bridge POST /set_manual_add_contacts
+```
+
+**Key Implementation Detail**: Always use full public_key for approval
+
+```python
+def approve_pending_contact(public_key: str) -> Tuple[bool, str]:
+    """
+    Args:
+        public_key: Full public key of the contact to approve (REQUIRED - full key works for all contact types)
+    """
+    # ...
+    response = requests.post(
+        f"{config.MC_BRIDGE_URL.replace('/cli', '/add_pending')}",
+        json={'selector': public_key.strip()},  # Full key ensures compatibility
+        timeout=DEFAULT_TIMEOUT + 5
+    )
+```
+
+**Rationale**: Testing documented in `technotes/pending-contacts-api.md` showed:
+- CLI contacts: Accept name prefix, key prefix, or full key
+- ROOM contacts: Only accept full public key
+- **Solution**: Always use full public_key for universal compatibility
+
+### 3. Backend - Flask API (api.py)
+
+**Added**: Four new REST endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/api/contacts/pending` | GET | List pending contacts |
+| `/api/contacts/pending/approve` | POST | Approve contact by public_key |
+| `/api/device/settings` | GET | Get persistent settings |
+| `/api/device/settings` | POST | Update manual_add_contacts |
+
+**Request/Response Examples**:
+
+```bash
+# Get pending contacts
+curl http://192.168.131.80:5000/api/contacts/pending
+
+# Response
+{
+  "success": true,
+  "pending": [
+    {

+      "public_key": "f9ef123abc..."
+    }
+  ],
+  "count": 1
+}
+
+# Approve contact (MUST use full public_key)
+curl -X POST http://192.168.131.80:5000/api/contacts/pending/approve \
+  -H 'Content-Type: application/json' \
+  -d '{"public_key":"f9ef123abc..."}'
+
+# Response

+}
+
+# Get settings

+  "message": "manual_add_contacts set to on",
+  "settings": {
+    "manual_add_contacts": true
+  }
+}

+    color: #6c757d;
+    word-break: break-all;
+}
+```
+
+### 5. Frontend - contacts.js
+
+**Key Features**:
+
+1. **Settings Management**
+```javascript
+async function loadSettings() {
+    const response = await fetch('/api/device/settings');
+    const data = await response.json();
+
+    if (data.success) {
+        manualApprovalEnabled = data.settings.manual_add_contacts || false;
+        updateApprovalUI(manualApprovalEnabled);
+    }
+}
+
+async function handleApprovalToggle(event) {
+    const enabled = event.target.checked;
+
+    const response = await fetch('/api/device/settings', {
+        method: 'POST',
+        headers: {'Content-Type': 'application/json'},
+        body: JSON.stringify({manual_add_contacts: enabled})
+    });
+
+    // Auto-reload pending contacts after toggle
+    setTimeout(() => loadPendingContacts(), 500);
+}
+```
+
+2. **Pending Contacts List**
+```javascript
+function createContactCard(contact, index) {
+    const card = document.createElement('div');
+    card.className = 'pending-contact-card';
+
+    // Contact name
+    const nameDiv = document.createElement('div');
+    nameDiv.className = 'contact-name';
+    nameDiv.textContent = contact.name;
+
+    // Truncated public key (full key in title attribute)
+    const keyDiv = document.createElement('div');
+    keyDiv.className = 'contact-key';
+    const truncatedKey = contact.public_key.substring(0, 16) + '...';
+    keyDiv.textContent = truncatedKey;
+    keyDiv.title = contact.public_key; // Hover shows full key
+
+    // Approve button
+    const approveBtn = document.createElement('button');
+    approveBtn.className = 'btn btn-success btn-action flex-grow-1';
+    approveBtn.innerHTML = '<i class="bi bi-check-circle"></i> Approve';
+    approveBtn.onclick = () => approveContact(contact, index);
+
+    // Copy full key button
+    const copyBtn = document.createElement('button');
+    copyBtn.className = 'btn btn-outline-secondary btn-action';
+    copyBtn.innerHTML = '<i class="bi bi-clipboard"></i> Copy Full Key';
+    copyBtn.onclick = () => copyPublicKey(contact.public_key, copyBtn);
+
+    // ...
+    return card;
+}
+```
+
+3. **Approve Contact** (CRITICAL: Always use full public_key)
+```javascript
+async function approveContact(contact, index) {
+    const cardEl = document.getElementById(`contact-${index}`);
+
+    // Disable buttons during approval
+    const buttons = cardEl.querySelectorAll('button');
+    buttons.forEach(btn => btn.disabled = true);
+
+    try {
+        const response = await fetch('/api/contacts/pending/approve', {
+            method: 'POST',
+            headers: {'Content-Type': 'application/json'},
+            body: JSON.stringify({
+                public_key: contact.public_key  // ALWAYS use full public_key (works for CLI, ROOM, etc.)
+            })
+        });
+
+        const data = await response.json();
+
+        if (data.success) {
+            showToast(`Approved: ${contact.name}`, 'success');
+
+            // Remove from list with fade animation
+            cardEl.style.opacity = '0';
+            cardEl.style.transition = 'opacity 0.3s';
+            setTimeout(() => {
+                cardEl.remove();
+                loadPendingContacts(); // Reload to update count
+            }, 300);
+        } else {
+            showToast('Failed to approve: ' + data.error, 'danger');
+            // Re-enable buttons on failure
+            buttons.forEach(btn => btn.disabled = false);
+        }
+    } catch (error) {
+        showToast('Network error: ' + error.message, 'danger');
+        buttons.forEach(btn => btn.disabled = false);
+    }
+}
+```
+
+4. **Copy to Clipboard**
+```javascript
+function copyPublicKey(publicKey, buttonEl) {
+    navigator.clipboard.writeText(publicKey).then(() => {
+        // Visual feedback
+        const originalHTML = buttonEl.innerHTML;
+        buttonEl.innerHTML = '<i class="bi bi-check"></i> Copied!';
+        buttonEl.classList.remove('btn-outline-secondary');
+        buttonEl.classList.add('btn-success');
+
+        setTimeout(() => {
+            buttonEl.innerHTML = originalHTML;
+            buttonEl.classList.remove('btn-success');
+            buttonEl.classList.add('btn-outline-secondary');
+        }, 2000);
+
+        showToast('Public key copied to clipboard', 'info');
+    }).catch(err => {
+        showToast('Failed to copy to clipboard', 'danger');
+    });
+}
+```
+
+5. **Toast Notifications**
+```javascript
+function showToast(message, type = 'info') {
+    const toastEl = document.getElementById('contactToast');
+    const bodyEl = toastEl.querySelector('.toast-body');
+
+    bodyEl.textContent = message;
+
+    // Apply color based on type
+    toastEl.classList.remove('bg-success', 'bg-danger', 'bg-info', 'bg-warning');
+    toastEl.classList.remove('text-white');
+
+    if (type === 'success' || type === 'danger' || type === 'warning') {
+        toastEl.classList.add(`bg-${type}`, 'text-white');
+    } else if (type === 'info') {
+        toastEl.classList.add('bg-info', 'text-white');
+    }
+
+    const toast = new bootstrap.Toast(toastEl, {
+        autohide: true,
+        delay: 3000
+    });
+    toast.show();
+}
+```
+
+### 6. Navigation Integration
+
+**Added to base.html** (line 73-76):
+```html
+<button class="list-group-item list-group-item-action d-flex align-items-center gap-3"
+        onclick="window.location.href='/contacts/manage';">
+    <i class="bi bi-person-check" style="font-size: 1.5rem;"></i>
+    <span>Contact Management</span>
+</button>
+```
+
+**Added route in views.py**:
+```python
+@views_bp.route('/contacts/manage')
+def contact_management():
+    """Contact Management view - manual approval settings and pending contacts list"""
+    return render_template(
+        'contacts.html',
+        device_name=config.MC_DEVICE_NAME,
+        refresh_interval=config.MC_REFRESH_INTERVAL
+    )
+```
+

+
+**Overall**: 9/9 tests PASSED ✅
+
+## Lessons Learned
+
+### 1. Full Public Key Requirement
+
+**Discovery**: Different contact types (CLI, ROOM, REP, SENS) have different matching behaviors in meshcli:
+- CLI contacts accept name prefix, key prefix, or full key
+- ROOM contacts only accept full public key
+
+**Solution**: Always use full public_key for approval to ensure universal compatibility.
+
+**Code Pattern**:
+```javascript
+// Good - works for all contact types
+body: JSON.stringify({
+    public_key: contact.public_key  // Full key from GET /pending_contacts
+})
+
+// Bad - may fail for ROOM contacts
+body: JSON.stringify({
+    selector: contact.name  // Won't work for ROOMs
+})
+```
+
+### 2. Settings Persistence Architecture
+
+**Decision**: File-based persistence vs environment variables
+
+**Chosen**: File-based persistence in volume-mounted directory
+- ✅ User can change settings via UI
+- ✅ Settings survive container restart
+- ✅ No need to edit docker-compose.yml
+- ✅ Future-proof for additional settings
+
+**Alternative Rejected**: Environment variables
+- ❌ Would require editing docker-compose.yml
+- ❌ Would require container restart to apply
+- ❌ User cannot change from UI
+
+### 3. Settings Application Timing
+
+**Challenge**: When to apply manual_add_contacts setting?
+
+**Solution**: Dual application
+1. **On bridge startup**: Read .webui_settings.json and apply to new session
+2. **On user toggle**: Write to file AND apply to running session immediately
+
+**Benefit**: User sees immediate effect without restart, but setting also persists.
+
+### 4. Mobile-First Design Principles
+
+**Applied**:
+- Touch-friendly buttons (min-height: 44px)
+- Large tap targets for icons
+- Responsive card layout
+- Toast notifications at bottom-right (thumb-accessible)
+- Truncated keys with copy option (avoid horizontal scroll)
+
+**Result**: UI works well on both desktop and mobile browsers.
+
+### 5. Error Handling Patterns
+
+**Pattern**: Always revert UI on failure
+
+```javascript
+async function handleApprovalToggle(event) {
+    const enabled = event.target.checked;
+
+    try {
+        // ...attempt to save
+        if (data.success) {
+            // Success - keep new state
+        } else {
+            // Failure - revert toggle
+            event.target.checked = !enabled;
+            showToast('Failed: ' + data.error, 'danger');
+        }
+    } catch (error) {
+        // Network error - revert toggle
+        event.target.checked = !enabled;
+        showToast('Network error', 'danger');
+    }
+}
+```
+
+**Benefit**: UI always reflects actual server state.
+
+### 6. Info Badge UX Pattern
+
+**Discovery**: When manual approval is OFF, pending list is always empty (confusing to users)
+
+**Solution**: Show info badge when manual approval is disabled:
+```html
+<div class="info-badge" id="approvalInfo" style="display: none;">
+    <i class="bi bi-info-circle"></i>
+    Pending contacts will only appear when manual approval is enabled.
+</div>
+```
+
+**Result**: Users understand why pending list is empty.
+
+## Documentation Updates
+
+### README.md
+- Added "Contact Management" to Key Features list
+- Added comprehensive "Contact Management" section in Usage
+- Renamed old section to "Managing Contacts (Cleanup)" to distinguish from new feature
+
+### .claude/instructions.md
+- Added 4 new API endpoints to reference
+- Added 4 new meshcli commands (pending_contacts, add_pending, get/set manual_add_contacts)
+- Updated Project Structure to include contacts.html and contacts.js
+- Added "Persistent Settings" section explaining .webui_settings.json
+
+### New Documentation Files
+- This file: `technotes/UI-Contact-Management-MVP-v1-completed.md`
+
+## Future Considerations
+
+### 1. Additional Settings
+
+The `.webui_settings.json` mechanism is designed to be extensible:
+
+```json
+{
+  "manual_add_contacts": true,
+  "future_setting_1": false,
+  "future_setting_2": "value"
+}
+```
+
+### 2. Batch Operations
+
+Currently, users must approve contacts one at a time. Future enhancement:
+- "Approve All" button
+- Checkbox selection for batch approval
+
+### 3. Contact Preview
+
+Before approval, show additional contact metadata:
+- Contact type (CLI, ROOM, REP, SENS)
+- First seen timestamp
+- Number of connection attempts
+
+### 4. Deny/Block Functionality
+
+Currently, pending contacts remain pending until approved. Future enhancement:
+- "Deny" button to permanently block a contact
+- Blacklist management
+
+### 5. Settings Export/Import
+
+Allow users to export/import `.webui_settings.json` for backup or migration to other devices.
+
+### 6. Real-Time Updates
+
+Currently, users must click "Refresh" to see new pending contacts. Future enhancement:
+- WebSocket for real-time pending contacts updates
+- Auto-refresh every N seconds (configurable)
+

+
+Backend (meshcore-bridge):
+- Added .webui_settings.json persistence mechanism
+- Modified session init to read and apply user settings
+- Added POST /set_manual_add_contacts endpoint
+- Default: manual_add_contacts=off (meshcli factory default)
+
+Backend (mc-webui):
+- Added 4 new CLI wrapper functions (get_pending_contacts, approve_pending_contact, get/set settings)
+- Added 4 new API endpoints (/api/contacts/pending, /api/contacts/pending/approve, /api/device/settings)
+- Added /contacts/manage route
+
+Frontend:
+- Created contacts.html template (mobile-first responsive design)
+- Created contacts.js (settings toggle, pending list, approve/copy buttons)
+- Added "Contact Management" to side menu
+- Toast notifications for user feedback
+
+Features:
+- Manual contact approval toggle (persistent across container restarts)
+- Pending contacts list with name and truncated public key
+- Approve button (sends full public_key for compatibility with all contact types)
+- Copy full public key to clipboard
+- Mobile-first UI (touch-friendly, Bootstrap 5)
+- Real-time feedback (loading/empty/error states)
+
+Persistence:
+- Settings saved to MC_CONFIG_DIR/.webui_settings.json

+# Contact Management MVP v2 - Implementation Complete
+
+**Date**: 2025-12-29
+**Status**: ✅ Completed (Pending Testing)
+**Branch**: `dev-2`
+**Related**: Builds on [UI-Contact-Management-MVP-v1-completed.md](UI-Contact-Management-MVP-v1-completed.md)
+
+## Overview
+
+Successfully implemented Contact Management MVP v2, which adds comprehensive management of existing contacts to the mc-webui interface. Users can now view, search, filter, and delete all contact types (CLI, REP, ROOM, SENS) with a mobile-first responsive UI.
+
+## Requirements
+
+Based on specification in `docs/UI-Contact-Management-MVP-v2.md`:
+
+### Functional Requirements
+1. **Existing Contacts Panel**
+   - Display all contacts (CLI, REP, ROOM, SENS)
+   - Show contact name, type, public key prefix, and path
+   - Capacity counter (X / 350) with color-coded warnings
+   - Delete functionality with confirmation modal
+
+2. **Search and Filter**
+   - Client-side search by name or public key prefix
+   - Filter by contact type (All / CLI / REP / ROOM / SENS)
+   - Real-time filtering as user types
+
+3. **UX Requirements**
+   - Mobile-first design (touch-friendly buttons)
+   - Loading states (spinner/placeholder)
+   - Delete confirmation modal (prevent accidental deletions)
+   - Color-coded type badges for visual distinction
+
+### Technical Requirements
+- Use existing `/api/contacts/detailed` endpoint pattern
+- Proxy to meshcore-bridge via HTTP (no direct meshcli access)
+- Vanilla JavaScript (no frameworks)
+- Bootstrap 5 for UI components
+- All code comments in English
+

+
+## Implementation Details
+
+### 1. Backend - Parser (`cli.py::get_all_contacts_detailed()`)
+
+**Challenge**: Parse variable-width text table output from `meshcli contacts`
+
+**Input format**:
+```
+MarWoj|* contacts
+KRA C                          REP   d103df18e0ff  Flood
+TK Zalesie Test 🦜              REP   df2027d3f2ef  Flood
+daniel5120 🔫                   CLI   4563b1621b58  1e93d90faa7c2e49df8f
+Szczwany-lis🦊                  CLI   02332896a4a6  Flood
+> 263 contacts in device
+```
+
+**Parsing strategy**:
+1. **Work backwards from end** - Rightmost columns have predictable format
+2. **Use public_key_prefix as anchor** - 12 hex chars are unique and reliable
+3. **Extract name carefully** - Handle spaces, Unicode, special chars
+4. **Validate extracted data** - Check type and hex format
+
+**Key code snippet**:
+```python
+def get_all_contacts_detailed() -> Tuple[bool, List[Dict], int, str]:
+    """Parse meshcli contacts output into structured data"""
+
+    # Split by whitespace
+    parts = stripped.split()
+    if len(parts) < 4:
+        continue  # Malformed line
+
+    # Extract from right to left
+    path_or_mode = parts[-1]
+    public_key_prefix = parts[-2]
+    type_label = parts[-3]
+
+    # Use public key as anchor to find name
+    pubkey_pos = stripped.rfind(public_key_prefix)
+    before_pubkey = stripped[:pubkey_pos].rstrip()
+
+    # Type is last word before pubkey
+    type_pos = before_pubkey.rfind(type_label)
+    if type_pos != -1:
+        name = before_pubkey[:type_pos].strip()
+
+    # Validate
+    if type_label not in ['CLI', 'REP', 'ROOM', 'SENS']:
+        type_label = 'UNKNOWN'
+
+    if not re.match(r'^[a-fA-F0-9]{12}$', public_key_prefix):
+        continue  # Skip invalid
+
+    contact = {
+        'name': name,
+        'public_key_prefix': public_key_prefix.lower(),
+        'type_label': type_label,
+        'path_or_mode': path_or_mode,
+        'raw_line': line  # Preserve for debugging
+    }
+```
+
+**Edge cases handled**:
+- ✅ Unicode emoji in names (🦜, 🦊, 🔫, etc.)
+- ✅ Polish characters (Łasin, Gdańsk)
+- ✅ Spaces in names ("TK Zalesie Test 🦜")
+- ✅ Type keyword in name ("CLI Test Node")
+- ✅ Variable spacing between columns
+- ✅ Hex path vs "Flood" mode
+- ✅ Final count line extraction
+
+**Testing**: Parsed 263 real contacts successfully (mix of CLI, REP, ROOM types with Unicode)
+
+### 2. Backend - Delete Function (`cli.py::delete_contact()`)
+
+**meshcli command**: `remove_contact <selector>`
+
+**Implementation**:
+```python
+def delete_contact(selector: str) -> Tuple[bool, str]:
+    """
+    Delete a contact using meshcli remove_contact command.
+
+    Args:
+        selector: Contact selector (name, public_key_prefix, or full public key)
+                 Using public_key_prefix is recommended for reliability.
+    """
+    success, stdout, stderr = _run_command(['remove_contact', selector.strip()])
+
+    if success:
+        message = stdout.strip() or f"Contact {selector} removed successfully"
+        return True, message
+    else:
+        error = stderr.strip() or "Failed to remove contact"
+        return False, error
+```
+
+**Selector options**:
+- Name (works for most contacts)
+- Public key prefix (12 hex chars - **recommended**)
+- Full public key
+
+**Recommendation**: Always use `public_key_prefix` for reliability across all contact types.
+
+### 3. API Endpoints (`api.py`)
+
+#### GET /api/contacts/detailed
+
+Returns detailed list of ALL contacts (CLI, REP, ROOM, SENS).
+
+**Response**:
+```json
+{
+  "success": true,
+  "count": 263,
+  "limit": 350,
+  "contacts": [
+    {
+      "name": "TK Zalesie Test 🦜",
+      "public_key_prefix": "df2027d3f2ef",
+      "type_label": "REP",
+      "path_or_mode": "Flood",
+      "raw_line": "..."
+    }
+  ]
+}
+```
+
+**Notes**:
+- Different from `/api/contacts` which returns only CLI contact names
+- Provides complete metadata needed for UI rendering
+- Includes device capacity info (count / limit)
+
+#### POST /api/contacts/delete
+
+Deletes a contact by selector.
+
+**Request**:
+```json
+{
+  "selector": "df2027d3f2ef"  // public_key_prefix recommended
+}
+```
+
+**Response** (success):
+```json
+{
+  "success": true,
+  "message": "Contact removed successfully"
+}
+```
+
+**Response** (error):
+```json
+{
+  "success": false,
+  "error": "Contact not found"
+}
+```
+
+### 4. Frontend - HTML Template (`contacts.html`)
+
+**Added sections**:
+
+1. **Existing Contacts Section**
+   - Header with counter badge and refresh button
+   - Search input (filter by name or public_key_prefix)
+   - Type filter dropdown (All / CLI / REP / ROOM / SENS)
+   - Contact cards list (dynamically populated)
+   - Loading/empty/error states
+
+2. **Delete Confirmation Modal**
+   - Bootstrap modal with danger theme
+   - Shows contact name and public_key_prefix
+   - Warns "This action cannot be undone"
+   - Cancel / Delete Contact buttons
+
+**CSS highlights**:
+```css
+/* Existing contact cards */
+.existing-contact-card {
+    background-color: white;
+    border: 1px solid #dee2e6;
+    border-radius: 0.5rem;
+    padding: 1rem;
+    box-shadow: 0 1px 3px rgba(0, 0, 0, 0.1);
+    transition: box-shadow 0.2s;
+}
+
+.existing-contact-card:hover {
+    box-shadow: 0 2px 8px rgba(0, 0, 0, 0.15);
+}
+
+/* Counter badge colors */
+.counter-ok { background-color: #28a745; }      /* Green: < 300 */
+.counter-warning { background-color: #ffc107; }  /* Yellow: 300-339 */
+.counter-alarm { background-color: #dc3545; }    /* Red: >= 340 */
+
+/* Pulse animation for alarm state */
+@keyframes pulse {
+    0%, 100% { opacity: 1; }
+    50% { opacity: 0.7; }
+}
+
+.counter-alarm {
+    animation: pulse 1.5s infinite;
+}
+```
+
+**Type badge colors**:
+- CLI: Blue (`bg-primary`)
+- REP: Green (`bg-success`)
+- ROOM: Cyan (`bg-info`)
+- SENS: Yellow (`bg-warning`)
+
+### 5. Frontend - JavaScript Logic (`contacts.js`)
+
+**New state variables**:
+```javascript
+let existingContacts = [];    // All contacts from API
+let filteredContacts = [];     // After applying search/filter
+let contactToDelete = null;    // Contact pending deletion
+```
+
+**Key functions**:
+
+#### loadExistingContacts()
+```javascript
+async function loadExistingContacts() {
+    // Show loading state
+    const response = await fetch('/api/contacts/detailed');
+    const data = await response.json();
+
+    existingContacts = data.contacts || [];
+    filteredContacts = [...existingContacts];
+
+    updateCounter(data.count, data.limit);
+    applyFilters();  // Render with current filters
+}
+```
+
+#### updateCounter()
+```javascript
+function updateCounter(count, limit) {
+    counterEl.textContent = `${count} / ${limit}`;
+
+    // Color logic
+    if (count >= 340) {
+        counterEl.classList.add('counter-alarm');  // Red pulsing
+    } else if (count >= 300) {
+        counterEl.classList.add('counter-warning'); // Yellow
+    } else {
+        counterEl.classList.add('counter-ok');       // Green
+    }
+}
+```
+
+#### applyFilters()
+```javascript
+function applyFilters() {
+    const searchTerm = searchInput.value.toLowerCase();
+    const selectedType = typeFilter.value;  // ALL, CLI, REP, ROOM, SENS
+
+    filteredContacts = existingContacts.filter(contact => {
+        // Type filter
+        if (selectedType !== 'ALL' && contact.type_label !== selectedType) {
+            return false;
+        }
+
+        // Search filter (name or public_key_prefix)
+        if (searchTerm) {
+            const nameMatch = contact.name.toLowerCase().includes(searchTerm);
+            const keyMatch = contact.public_key_prefix.toLowerCase().includes(searchTerm);
+            return nameMatch || keyMatch;
+        }
+
+        return true;
+    });
+
+    renderExistingList(filteredContacts);
+}
+```
+
+#### createExistingContactCard()
+```javascript
+function createExistingContactCard(contact, index) {
+    const card = document.createElement('div');
+    card.className = 'existing-contact-card';
+
+    // Name + Type badge
+    const nameDiv = document.createElement('div');
+    nameDiv.textContent = contact.name;
+
+    const typeBadge = document.createElement('span');
+    typeBadge.className = 'badge type-badge';
+    typeBadge.textContent = contact.type_label;
+
+    // Color-code by type
+    switch (contact.type_label) {
+        case 'CLI':  typeBadge.classList.add('bg-primary'); break;
+        case 'REP':  typeBadge.classList.add('bg-success'); break;
+        case 'ROOM': typeBadge.classList.add('bg-info'); break;
+        case 'SENS': typeBadge.classList.add('bg-warning'); break;
+    }
+
+    // Public key
+    const keyDiv = document.createElement('div');
+    keyDiv.className = 'contact-key';
+    keyDiv.textContent = contact.public_key_prefix;
+
+    // Action buttons (Copy Key + Delete)
+    const copyBtn = createButton('Copy Key', () => copyContactKey(...));
+    const deleteBtn = createButton('Delete', () => showDeleteModal(contact));
+
+    return card;
+}
+```
+
+#### confirmDelete()
+```javascript
+async function confirmDelete() {
+    const response = await fetch('/api/contacts/delete', {
+        method: 'POST',
+        headers: { 'Content-Type': 'application/json' },
+        body: JSON.stringify({
+            selector: contactToDelete.public_key_prefix  // Use prefix for reliability
+        })
+    });
+
+    if (data.success) {
+        showToast(`Deleted: ${contactToDelete.name}`, 'success');
+        modal.hide();
+
+        // Reload contacts list
+        setTimeout(() => loadExistingContacts(), 500);
+    }
+}
+```
+
+## User Workflows
+
+### Workflow 1: View All Contacts
+
+1. User navigates to Contact Management page
+2. Page auto-loads existing contacts via `GET /api/contacts/detailed`
+3. Parser extracts structured data from meshcli output
+4. Frontend renders contact cards with:
+   - Name (bold)
+   - Type badge (color-coded)
+   - Public key prefix (monospace)
+   - Action buttons (Copy, Delete)
+5. Counter badge shows "263 / 350" (green)
+
+### Workflow 2: Search for a Contact
+
+1. User types "Zalesie" in search box
+2. `applyFilters()` triggered on input event
+3. Filters `existingContacts` by:
+   - Name contains "zalesie" (case-insensitive)
+   - OR public_key_prefix contains "zalesie"
+4. `renderExistingList()` re-renders with filtered results
+5. Results update instantly as user types
+
+### Workflow 3: Filter by Type
+
+1. User selects "REP" from type dropdown
+2. `applyFilters()` triggered on change event
+3. Filters contacts where `type_label === 'REP'`
+4. Only repeaters shown in list
+5. Counter badge still shows total count (not filtered count)
+
+### Workflow 4: Delete a Contact
+
+1. User clicks red "Delete" button on contact card
+2. `showDeleteModal(contact)` opens Bootstrap modal
+3. Modal displays:
+   - Contact name: "TK Zalesie Test 🦜"
+   - Public key: "df2027d3f2ef"
+   - Warning: "This action cannot be undone"
+4. User clicks "Delete Contact" button
+5. `confirmDelete()` sends `POST /api/contacts/delete`
+6. Request body: `{"selector": "df2027d3f2ef"}`
+7. Backend executes `meshcli remove_contact df2027d3f2ef`
+8. On success:
+   - Toast notification: "Deleted: TK Zalesie Test 🦜"
+   - Modal closes
+   - Contact list auto-refreshes after 500ms
+9. Counter badge updates to "262 / 350"
+
+### Workflow 5: Monitor Capacity
+
+**Scenario A: Normal usage (< 300 contacts)**
+- Counter badge: "150 / 350" (green background)
+- No warnings
+
+**Scenario B: Approaching limit (300-339 contacts)**
+- Counter badge: "315 / 350" (yellow background)
+- User notices warning color
+
+**Scenario C: Critical (≥ 340 contacts)**
+- Counter badge: "342 / 350" (red background, pulsing animation)
+- User should delete some contacts soon
+
+## Contacts Parser - Technical Deep Dive
+
+### Problem
+
+`meshcli contacts` outputs a text table with:
+- Variable-width columns (not fixed positions)
+- Names containing spaces, Unicode emoji, special chars
+- No clear delimiters between columns
+
+### Solution: Backward Parsing with Anchor
+
+**Step 1**: Split by whitespace
+```python
+parts = stripped.split()
+# ['TK', 'Zalesie', 'Test', '🦜', 'REP', 'df2027d3f2ef', 'Flood']
+```
+
+**Step 2**: Extract rightmost columns (predictable)
+```python
+path_or_mode = parts[-1]          # 'Flood'
+public_key_prefix = parts[-2]     # 'df2027d3f2ef'
+type_label = parts[-3]             # 'REP'
+```
+
+**Step 3**: Use public_key_prefix as anchor
+```python
+pubkey_pos = stripped.rfind('df2027d3f2ef')
+# Find position in original string (preserves spacing)
+
+before_pubkey = stripped[:pubkey_pos].rstrip()
+# 'TK Zalesie Test 🦜              REP'
+```
+
+**Step 4**: Extract name (everything before type)
+```python
+type_pos = before_pubkey.rfind('REP')
+name = before_pubkey[:type_pos].strip()
+# 'TK Zalesie Test 🦜'
+```
+
+**Why this works**:
+- Public key is unique 12-hex pattern (reliable anchor)
+- Working from right to left avoids variable-length name issues
+- Preserves Unicode by working with full strings
+- Handles spaces in names naturally
+
+### Validation
+
+```python
+# Type validation
+if type_label not in ['CLI', 'REP', 'ROOM', 'SENS']:
+    type_label = 'UNKNOWN'
+
+# Public key format validation
+if not re.match(r'^[a-fA-F0-9]{12}$', public_key_prefix):
+    continue  # Skip malformed line
+```
+
+### Count Extraction
+
+```python
+# Extract total count from final line
+# "> 263 contacts in device"
+if line.strip().startswith('>') and 'contacts in device' in line:
+    try:
+        total_count = int(re.search(r'> (\d+) contacts', line).group(1))
+    except:
+        pass  # Fallback to len(contacts)
+```
+
+## Testing Plan
+
+### Manual Testing Checklist

+
+### Logging
+
+Check logs for delete operations:
+
+```bash
+# mc-webui container
+docker compose logs -f mc-webui | grep -i "delete"
+
+# meshcore-bridge container (where remove_contact executes)
+docker compose logs -f meshcore-bridge | grep -i "remove_contact"
+```
+
+**Expected log entries**:
+```
+mc-webui: POST /api/contacts/delete {"selector": "df2027d3f2ef"}
+meshcore-bridge: Executing command: ['remove_contact', 'df2027d3f2ef']
+meshcore-bridge: Command succeeded: Contact removed
+```
