### 2. ✅ Claude API Integration

**Test Script:** `/tmp/test-claude-api.js`

**Test Results:**
```json
{
  "status": "✅ WORKING",
  "model": "claude-sonnet-4-5-20250929",
  "test_case": "Instruction classification",
  "response": {
    "quadrant": "TACTICAL",
    "persistence": "MEDIUM",
    "reasoning": "Specifies a concrete technical implementation detail..."
  },
  "usage": {
    "input_tokens": 95,
    "output_tokens": 92,
    "total": 187
  }
}
```

**Verified:**
- API key valid and working ✅
- Model responding correctly ✅
- Connection from production VPS successful ✅
- Classification logic accurate ✅

### 3. ✅ Blog Curation System (TRA-OPS-0002)

**Files Created/Modified:**

#### `/src/services/ClaudeAPI.service.js` (NEW)
**Purpose:** Centralized Claude API integration service

**Methods:**
- `sendMessage(messages, options)` - Core API communication
- `extractTextContent(response)` - Parse text from response
- `extractJSON(response)` - Parse JSON from response (handles markdown code blocks)
- `classifyInstruction(text)` - Tractatus instruction classification
- **`generateBlogTopics(audience, theme)`** - Blog topic suggestions
- `classifyMediaInquiry(inquiry)` - Media priority classification
- `draftMediaResponse(inquiry, priority)` - Draft media responses
- `analyzeCaseRelevance(caseStudy)` - Case study relevance scoring
- `curateResource(resource)` - Resource directory curation

**Error Handling:**
- API key validation
- HTTP error handling
- JSON parsing with fallback
- Detailed logging

#### `/src/controllers/blog.controller.js` (MODIFIED)
**Added:** `suggestTopics(req, res)` function

**Governance Flow:**
1. Validate input (audience must be: researcher/implementer/advocate/general)
2. **BoundaryEnforcer check** - Verify editorial suggestions allowed
3. **GovernanceLog entry** - Audit trail for all actions
4. **Claude API call** - Generate 5-7 topic suggestions
5. **ModerationQueue entry** - Queue for human approval
6. Return suggestions with governance metadata

**TRA-OPS-0002 Compliance:**
- ✅ AI suggests topics only (does not write posts)
- ✅ All suggestions go to moderation queue
- ✅ Human must approve topics before writing
- ✅ Human writes all blog posts
- ✅ Boundary check before AI action
- ✅ Full audit trail in governance logs

#### `/src/routes/blog.routes.js` (MODIFIED)
**Added:** `POST /api/blog/suggest-topics` route

**Route Protection:**
- `authenticateToken` - JWT authentication required
- `requireRole('admin')` - Admin-only access
- `validateRequired(['audience'])` - Input validation
- `asyncHandler` - Error handling wrapper

**Request Format:**
```json
POST /api/blog/suggest-topics
Authorization: Bearer <JWT_TOKEN>
Content-Type: application/json

{
  "audience": "researcher|implementer|advocate|general",
  "theme": "AI safety regulation" // optional
}
```

**Response Format:**
```json
{
  "success": true,
  "message": "Blog topic suggestions generated. Awaiting human review and approval.",
  "queue_id": "68e4a5f32...",
  "suggestions": [
    {
      "title": "...",
      "subtitle": "...",
      "target_word_count": 1200,
      "key_points": ["...", "...", "..."],
      "tractatus_angle": "..."
    }
  ],
  "governance": {
    "policy": "TRA-OPS-0002",
    "boundary_check": { "allowed": true, ... },
    "requires_approval": true,
    "note": "Topics are suggestions only. Human must write all blog posts."
  }
}
```

#### `/src/models/GovernanceLog.model.js` (NEW)
**Purpose:** Audit trail for all Tractatus governance actions

**Schema:**
```javascript
{
  action: 'BLOG_TOPIC_SUGGESTION',
  user_id: ObjectId,
  user_email: 'admin@agenticgovernance.digital',
  timestamp: ISODate,
  quadrant: 'OPERATIONAL',
  boundary_check: { allowed: true, ... },
  outcome: 'QUEUED_FOR_APPROVAL',
  details: { audience: 'researcher', theme: 'AI safety' },
  service: 'blog_curation',
  environment: 'production'
}
```

**Methods:**
- `create(data)` - Create log entry
- `findByAction(action)` - Query logs by action type
- `findByUser(userId)` - Query logs by user
- `findBlocked()` - Find all blocked actions
- `findByOutcome(outcome)` - Query by outcome
- `findByQuadrant(quadrant)` - Query by Tractatus quadrant
- `getStatistics(startDate, endDate)` - Aggregate statistics
- `deleteOldLogs(days)` - Retention policy enforcement

#### `/src/models/ModerationQueue.model.js` (MODIFIED)
**Purpose:** Human oversight queue for AI actions

**Changes:**
- Made `item_id` optional (not all moderation items have existing database items)
- Added `type` field for flexible categorization
- Added `data` field for flexible AI output storage
- Added `ai_generated` and `ai_version` tracking
- Added `requires_human_approval` flag
- Added `metadata` object for governance data

**New Schema:**
```javascript
{
  type: 'BLOG_TOPIC_SUGGESTION',
  reference_collection: 'blog_posts', // optional
  reference_id: ObjectId, // optional
  quadrant: 'OPERATIONAL',
  data: {
    audience: 'researcher',
    theme: 'AI safety',
    suggestions: [...],
    requested_by: 'admin@agenticgovernance.digital'
  },
  ai_generated: true,
  ai_version: 'claude-sonnet-4-5',
  requires_human_approval: true,
  status: 'PENDING_APPROVAL',
  created_by: ObjectId,
  metadata: {
    boundary_check: {...},
    governance_policy: 'TRA-OPS-0002'
  }
}
```

**Backwards Compatibility:**
- Kept legacy `item_type` and `item_id` fields
- Existing methods still work

## Testing Blog Curation System

### Manual Test (Future)

**Prerequisites:**
1. Admin user created: admin@agenticgovernance.digital / TempAdmin@2025
2. JWT token obtained via /api/auth/login
3. Claude API key configured in .env

**Test Steps:**

1. **Login as admin:**
```bash
curl -X POST https://agenticgovernance.digital/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"admin@agenticgovernance.digital","password":"TempAdmin@2025"}'

# Save the returned token
TOKEN="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
```

2. **Request blog topic suggestions:**
```bash
curl -X POST https://agenticgovernance.digital/api/blog/suggest-topics \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "audience": "researcher",
    "theme": "AI safety regulation"
  }' | jq
```

3. **Expected Response:**
```json
{
  "success": true,
  "message": "Blog topic suggestions generated. Awaiting human review and approval.",
  "queue_id": "68e4a5f32...",
  "suggestions": [
    {
      "title": "Regulatory Alignment Through Architectural Constraints: How Tractatus Meets AI Act Requirements",
      "subtitle": "Demonstrating technical compliance with governance frameworks",
      "target_word_count": 1200,
      "key_points": [
        "EU AI Act risk classification and how Tractatus addresses high-risk systems",
        "Architectural vs. behavioral compliance approaches",
        "Cross-reference validation as regulatory evidence"
      ],
      "tractatus_angle": "Shows how framework principles map to regulatory requirements"
    }
  ],
  "governance": {
    "policy": "TRA-OPS-0002",
    "boundary_check": { "allowed": true },
    "requires_approval": true,
    "note": "Topics are suggestions only. Human must write all blog posts."
  }
}
```

4. **Check moderation queue:**
```bash
curl https://agenticgovernance.digital/api/admin/moderation?type=BLOG_TOPIC_SUGGESTION \
  -H "Authorization: Bearer $TOKEN" | jq
```

5. **Check governance logs:**
```bash
curl https://agenticgovernance.digital/api/governance/logs?action=BLOG_TOPIC_SUGGESTION \
  -H "Authorization: Bearer $TOKEN" | jq
```

### Expected Behavior

**Governance Checks:**
- ✅ BoundaryEnforcer allows topic suggestions (OPERATIONAL quadrant)
- ✅ Action logged in governance_logs collection
- ✅ Moderation queue entry created
- ✅ HTTP 200 response with suggestions

**If BoundaryEnforcer blocks action:**
- ❌ HTTP 403 Forbidden
- ❌ Response includes boundary violation details
- ✅ Still logged in governance_logs (outcome: BLOCKED)

**Error Cases:**
- Missing `audience`: HTTP 400 Bad Request
- Invalid `audience`: HTTP 400 Bad Request
- Missing JWT token: HTTP 401 Unauthorized
- Non-admin user: HTTP 403 Forbidden
- Claude API failure: HTTP 502 Bad Gateway

## Governance Compliance

### TRA-OPS-0002: AI-Curated Blog Content

**Policy Requirements:**
