+   - Campaign Type: Global comm
+   - Accessible via API
+

+
+## 📋 TODO: PHP Interface (B1→B2 Workflow)
+
+### 1. Add New Tab in workflow_v3.php
+
+**Location:** After Upload from Box tab, before closing tabs div
+
+**Add:**
+```php
+<button class="tab <?= $currentTab === 'b1-b2' ? 'active' : '' ?>"
+        onclick="switchTab('b1-b2')">
+    🌍 Global Masters (B1→B2)
+</button>
+```
+
+### 2. Add Tab Content Section
+
+**Template (copy from Download Workflow A1→A2):**
+```php
+<!-- Global Masters Workflow Tab -->
+<div id="tab-b1-b2" class="tab-content <?= $currentTab === 'b1-b2' ? 'active' : '' ?>">
+    <h2>🌍 Global Masters Workflow: B1 → B2</h2>
+    <p>Download Global Master assets and prepare for re-mastering</p>
+
+    <form method="POST">
+        <input type="hidden" name="tab" value="b1-b2">
+        <input type="hidden" name="action" value="load_campaigns_b1">
+        <button type="submit" class="btn btn-primary">
+            Load Campaigns (Content Scaling Status = B1)
+        </button>
+    </form>
+
+    <!-- Rest similar to A1→A2 workflow -->
+</div>
+```
+
+### 3. Add Action Handlers
+
+**Actions to add:**
+- `load_campaigns_b1` - Load campaigns with status B1
+- `select_campaign_b1` - Select a B1 campaign
+- `get_global_master_assets` - Get master assets from campaign
+- `download_global_asset` - Download individual asset
+- `download_all_global_assets` - Download all assets
+- `download_and_upload_global_to_box` - Download from DAM, upload to Box
+- `update_status_to_b2` - Update status B1 → B2
+- `reset_to_b1` - Reset status to B1 (for testing)
+
+### 4. Add Status Change Buttons in Debug View
+
+**Location:** In the debug campaign display (around line 1920)
+
+**Add for each campaign:**
+```php
+<?php if ($campaign['status'] === 'B1'): ?>
+    <button type="submit" class="btn btn-success">
+        Update to B2
+    </button>
+<?php elseif ($campaign['status'] === 'B2'): ?>
+    <button type="submit" class="btn btn-warning">
+        Reset to B1
+    </button>
+<?php endif; ?>
+```
+
+---
+
+## 📋 TODO: Python Script (b1_to_b2_download.py)
+
+### Create New Script
+
+**File:** `Python-Version/scripts/b1_to_b2_download.py`
+
+**Differences from A1→A2:**
+1. Search for B1 status (not A1)
+2. Search for "Global comm" campaigns (not "Local Adaptation")
+3. Use `dam.search_campaigns(status='B1')` - need to update DAM client
+4. Update status B1 → B2 (not A1 → A2)
+5. Same folder logic (348304357505)
+6. Same Box upload with tracking IDs
+7. Same all-done check
+8. Different email templates (b1_to_b2_complete, b1_to_b2_partial)
+
+### Update DAM Client
+
+**File:** `Python-Version/scripts/shared/dam_client.py`
+
+**Add method:**
+```python
+def search_global_campaigns(self, status=None):
+    """Search for Global comm campaigns (B-series)"""
+    # Change search condition value to 'Global comm'
+```
+
+### Email Templates
+
+**Add to notifier.py:**
+- `b1_to_b2_complete` - Success email for B1→B2
+- `b1_to_b2_partial` - Partial completion for B1→B2
+
+---
+
+## 🔧 Implementation Steps
+
+### Step 1: PHP Interface (2-3 hours)
+1. Add B1→B2 tab to workflow
+2. Copy and adapt A1→A2 workflow code
+3. Update action handlers for B1/B2
+4. Add status change buttons
+5. Test with folder: 676f2bcde4c7bcf7ef783e97f7495069bf50b6bc
+
+### Step 2: Python Script (1-2 hours)
+1. Copy a1_to_a2_download.py → b1_to_b2_download.py
+2. Update search to use Global comm campaigns
+3. Update status codes (B1, B2)
+4. Add email templates
+5. Test with B1 campaign
+
+### Step 3: Testing (1 hour)
+1. Test PHP workflow with NUTELLA campaign
+2. Test Python script
+3. Verify Box uploads
+4. Verify database storage
+5. Verify status changes
+6. Verify emails

+
+## 📝 Code Templates
+
+### loadCampaignsByStatus for B1
+
+```php
+function loadCampaignsByStatusB1($testRunner, $status)
+{
+    $statusManager = createStatusManager($testRunner);
+    $response = $statusManager->searchGlobalCampaigns($testRunner);
+
+    if ($response['success']) {
+        $allCampaigns = CampaignFormatter::getActionableCampaigns($response['body'], []);
+        $filteredCampaigns = CampaignFormatter::getActionableCampaigns($response['body'], ['status' => $status]);
+        return $filteredCampaigns;
+    }
+
+    return [];
+}
+```
+
+### Python DAM Client Search
+
+```python
+def search_global_campaigns(self, status=None):
+    """Search for Global comm campaigns (B-series)"""
+    search_condition = {
+        "search_condition_list": {
+            "search_condition": [
+                {
+                    "type": "com.artesia.search.SearchScalarCondition",
+                    "metadata_field_id": "ARTESIA.FIELD.CONTAINER TYPE NAME",
+                    "relational_operator_id": "ARTESIA.OPERATOR.CHAR.CONTAINS",
+                    "value": "GLOBALCAMPAING",
+                    "left_paren": "(",
+                    "right_paren": ")"
+                },
+                {
+                    "type": "com.artesia.search.SearchScalarCondition",
+                    "metadata_field_id": "FERRERO.FIELD.CAMPAIGN TYPE",
+                    "relational_operator_id": "ARTESIA.OPERATOR.CHAR.CONTAINS",
+                    "value": "Global comm",
+                    "relational_operator": "and"
+                }
+            ]
+        }
+    }
+    # ... rest same as search_campaigns
+```
+
+---
+
+## 🎯 Expected Behavior
+
+**B1→B2 PHP Workflow:**
+1. Load campaigns with status B1 (Global comm campaigns)
+2. Select campaign (e.g., NUTELLA PLANT-BASED LAUNCH)
+3. Get Global Master Assets
+4. Download assets
+5. Upload to Box with tracking IDs
+6. Update status B1 → B2 when all done
+
+**B1→B2 Python Script:**
+```bash
+python scripts/b1_to_b2_download.py
+```
+- Searches for B1 Global campaigns
+- Processes first one
+- Downloads master assets
+- Uploads to Box
+- Updates B1 → B2
+- Sends webhook and email
+
+**Cron Setup:**
+```bash
+# A1→A2: Local Adaptation every 5 minutes
+*/5 * * * * python scripts/a1_to_a2_download.py
+
+# B1→B2: Global Masters every 5 minutes
+*/5 * * * * python scripts/b1_to_b2_download.py
+```
