🔍 FEATURE 1: AUTO-CLUSTER VALIDATION

Implementation Details

Shared Validation Function:

# backend/igny8_core/ai/validators/cluster_validators.py

def validate_minimum_keywords(keyword_ids, account=None, min_required=5):
    """
    Validates that at least 5 keywords are available for clustering
    Returns: {'valid': bool, 'error': str (if invalid), 'count': int}
    """

Three Integration Points:

1. Auto-Cluster Function (auto_cluster.py)

   • Validates before AI processing
   • Returns error to task caller

2. Automation Pipeline (automation_service.py)

   • Validates before Stage 1 starts
   • Skips stage with proper logging if insufficient keywords

3. API Endpoint (planner/views.py)

   • Validates before queuing task
   • Returns HTTP 400 error with clear message

Behavior

✅ With 5+ Keywords:

• Auto-cluster proceeds normally
• Automation Stage 1 runs
• Credits deducted

❌ With < 5 Keywords:

• Manual Auto-Cluster: Returns error immediately
• Automation: Skips Stage 1 with warning in logs
• No credits deducted

Error Messages

Frontend (API Response):

{
  "error": "Insufficient keywords for clustering. Need at least 5 keywords, but only 3 available.",
  "count": 3,
  "required": 5
}

Backend Logs:

[AutoCluster] Validation failed: Insufficient keywords for clustering. Need at least 5 keywords, but only 3 available.

Automation Logs:

[AutomationService] Stage 1 skipped: Insufficient keywords for clustering. Need at least 5 keywords, but only 2 available.

🔍 FEATURE 2: CREDIT COST CONFIGURATION

Implementation Details

New Database Model:

# CreditCostConfig model fields:
- operation_type (unique, indexed)
- credits_cost (integer)
- unit (per_request, per_100_words, per_image, etc.)
- display_name
- description
- is_active
- previous_cost (audit trail)
- updated_by (tracks admin user)
- created_at, updated_at

Django Admin Interface:

• ✅ List view with color-coded costs
• ✅ Change indicators (📈 increased, 📉 decreased)
• ✅ Filter by active status, unit
• ✅ Search by operation type, name
• ✅ Audit trail (who changed, when, previous value)

Updated CreditService:

# Before: Hardcoded only
base_cost = CREDIT_COSTS.get(operation_type)

# After: Database first, fallback to constants
try:
    config = CreditCostConfig.objects.get(operation_type=op, is_active=True)
    return config.credits_cost
except:
    return CREDIT_COSTS.get(operation_type)  # Fallback

Key Features

✅ Backward Compatible:

• Existing code continues to work
• Falls back to constants if database config doesn't exist
• No breaking changes

✅ Admin-Friendly:

• No code deployment needed to change costs
• Visual indicators for cost changes
• Audit trail for accountability

✅ Flexible Pricing:

• Different units (per request, per 100 words, per image)
• Can enable/disable operations
• Track cost history

🚀 DEPLOYMENT STEPS

Step 1: Create Migration

cd /data/app/igny8/backend

# Create migration for CreditCostConfig model
python manage.py makemigrations billing --name add_credit_cost_config

# Review the migration
python manage.py sqlmigrate billing <migration_number>

Step 2: Apply Migration

# Apply migration
python manage.py migrate billing

# Verify table created
python manage.py dbshell
\dt igny8_credit_cost_config
\q

Step 3: Initialize Credit Costs

# Run management command to populate database
python manage.py init_credit_costs

# Expected output:
# ✅ Created: Auto Clustering - 10 credits
# ✅ Created: Idea Generation - 15 credits
# ✅ Created: Content Generation - 1 credits
# ...
# ✅ Complete: 9 created, 0 already existed

Step 4: Restart Services

# Restart Django/Gunicorn
sudo systemctl restart igny8-backend

# Or if using Docker
docker-compose restart backend

# Or if using supervisor
sudo supervisorctl restart igny8-backend

Step 5: Verify Admin Access

1. Login to Django Admin: https://your-domain.com/admin/
2. Navigate to: Billing → Credit Cost Configurations
3. Verify all operations are listed
4. Test editing a cost (change and save)
5. Verify change indicator shows up

🧪 TESTING CHECKLIST

Auto-Cluster Validation Tests

• Test 1: Try auto-cluster with 0 keywords

  • Expected: Error "No keyword IDs provided"

• Test 2: Try auto-cluster with 3 keywords (via API)

  • Expected: HTTP 400 error "Insufficient keywords... need at least 5, but only 3 available"

• Test 3: Try auto-cluster with exactly 5 keywords

  • Expected: Success, clustering starts

• Test 4: Run automation with 2 keywords in site

  • Expected: Stage 1 skipped, automation proceeds to Stage 2
  • Check logs: Should show skip reason

• Test 5: Run automation with 10 keywords in site

  • Expected: Stage 1 runs normally

Credit Cost Configuration Tests

• Test 6: Access Django Admin → Credit Cost Configurations

  • Expected: All 9 operations listed

• Test 7: Edit a cost (e.g., change clustering from 10 to 15)

  • Expected: Save succeeds, change indicator shows 📈 (10 → 15)

• Test 8: Run auto-cluster after cost change

  • Expected: New cost (15) is used, not old constant (10)
  • Check: CreditTransaction and CreditUsageLog reflect new cost

• Test 9: Disable an operation (set is_active=False)

  • Expected: Falls back to constant value

• Test 10: Check audit trail

  • Expected: updated_by shows admin username, previous_cost shows old value

Backward Compatibility Tests

• Test 11: Delete all CreditCostConfig records

  • Expected: System still works using CREDIT_COSTS constants

• Test 12: Run existing AI operations (content generation, image generation)

  • Expected: No errors, credits deducted correctly

✅ SAFETY & ROLLBACK

Rollback Plan (if issues occur)

1. Revert Code Changes:

cd /data/app/igny8
git checkout HEAD~1 backend/igny8_core/ai/validators/
git checkout HEAD~1 backend/igny8_core/ai/functions/auto_cluster.py
git checkout HEAD~1 backend/igny8_core/business/automation/services/automation_service.py
git checkout HEAD~1 backend/igny8_core/modules/planner/views.py
git checkout HEAD~1 backend/igny8_core/business/billing/

2. Rollback Migration (if needed):

python manage.py migrate billing <previous_migration_number>

3. Restart Services:

sudo systemctl restart igny8-backend

Safety Guarantees

✅ No Data Loss:

• No existing data is modified
• Only adds new validation logic and new database table
• Existing credits, transactions, usage logs untouched

✅ Backward Compatible:

• Auto-cluster still works with 5+ keywords (no change in behavior)
• Credit costs fall back to constants if database config missing
• All existing API calls continue to work

✅ Isolated Changes:

• Validation is additive (only rejects invalid requests)
• Credit service checks database first, but has fallback
• No changes to core business logic

• 🔵 Running automation: Stage skipped with warning in logs
• 🔵 No confusion about why clustering failed

Credit Cost Configuration

Benefits:

• ✅ Instant cost updates (no code deployment)
• ✅ A/B testing pricing strategies
• ✅ Promotional pricing for events
• ✅ Audit trail for compliance

Admin Experience:

• 🔵 Change clustering cost from 10 → 15 credits in < 1 minute
