System Architecture

Engagement System

User Actions → Points/XP Award → Profile Update → Level Calculation → Achievement Check
                     ↓
              Transaction Log
                     ↓
              Audit Trail

Flow Example:

1. User posts comment → comment_create event
2. Service checks daily cap (max 10/day)
3. Awards 5 points + 5 XP
4. Logs transaction with metadata
5. Updates user profile atomically
6. Recalculates level from total XP
7. Checks achievement milestones
8. Awards achievement if criteria met

Comments System

User Submits Comment → Spam Detection → Bad Words Filter → Status Decision → Engagement Points → Save
                                                                    ↓
                                                    visible (public) | hidden (review)

Moderation Workflow:

1. Comment created with spam score
2. Auto-hidden if sensitive words
3. Admin reviews reports queue
4. Decision: approve/hide/ban user
5. User can appeal ban
6. Admin approves/rejects appeal

Quick Deployment Guide

Step 1: Database Migration

# Run migrations
cd /path/to/fotbal-club
make migrate-up

# Or manually:
psql $DATABASE_URL -f database/migrations/20251102000001_create_engagement_system.up.sql
psql $DATABASE_URL -f database/migrations/20251102000002_create_comments_system.up.sql

Verify:

-- Check tables exist
SELECT table_name FROM information_schema.tables 
WHERE table_schema = 'public' 
AND table_name IN ('user_profiles', 'points_transactions', 'achievements', 'reward_items', 'reward_redemptions', 'comments', 'comment_bans', 'comment_reactions', 'comment_reports', 'unban_requests');

-- Should return 10 rows

-- Check default data
SELECT COUNT(*) FROM achievements; -- Should be 8
SELECT COUNT(*) FROM reward_items WHERE type = 'avatar_upload_unlock'; -- Should be 1

Step 2: Backend Configuration

Environment Variables (.env):

# Already configured (verify these exist)
SMTP_HOST=smtp.example.com
SMTP_PORT=587
SMTP_USER=noreply@yourclub.com
SMTP_PASS=********
SMTP_FROM=noreply@yourclub.com

CANONICAL_BASE_URL=https://yourclub.com
JWT_SECRET=********

No code changes needed - All backend code already in place!

Step 3: Frontend Build

cd frontend
npm install  # Installs any missing deps
npm run build

# Or with Docker:
docker-compose up --build frontend

Verify Build:

• Check frontend/build/dist/ contains compiled assets
• Verify no TypeScript errors
• Ensure utils loaded: engagementHelpers.ts, commentsHelpers.ts

Step 4: Restart Services

# With Docker
docker-compose restart backend frontend

# Or manually
pkill -f fotbal-club
./bin/fotbal-club &

Step 5: Smoke Tests

Engagement System:

1. ✅ Create test user account
2. ✅ Post a comment → Check points awarded
3. ✅ Visit /fan-zone → See profile
4. ✅ Check leaderboard → User appears
5. ✅ Admin: Create a reward
6. ✅ User: Redeem reward
7. ✅ Admin: Approve redemption
8. ✅ User: Check email for confirmation

Comments System:

1. ✅ Post comment on article
2. ✅ React to comment
3. ✅ Edit own comment
4. ✅ Report comment
5. ✅ Admin: View reports
6. ✅ Admin: Hide comment
7. ✅ Admin: Ban user (temporary)
8. ✅ User: Request unban
9. ✅ Admin: Approve unban

Testing Procedures

Manual Testing

Engagement Flow

1. Register new user → Profile auto-created with username
2. Edit username → Validation works
3. Post 5 comments → 25 points earned
4. Vote in poll → 3 points earned
5. Check achievements → "First comment" unlocked
6. Browse rewards → List displays
7. Redeem avatar → Points deducted, avatar applied
8. Check transactions → All logged
9. View leaderboard → Ranking correct
10. Upload custom avatar (after unlock) → Success

Comments Flow

1. Post normal comment → Visible immediately
2. Post spammy comment (excessive caps) → Hidden or flagged
3. Post with bad word → Censored
4. React to comment → Emoji appears
5. Report comment → Admin notified
6. Admin ban user → Comment creation blocked
7. User appeal → Request submitted
8. Admin approve → User can comment again

Automated Testing (Future)

Unit Tests (Go):

func TestComputeLevel(t *testing.T) {
    assert.Equal(t, 1, services.ComputeLevel(0))
    assert.Equal(t, 2, services.ComputeLevel(100))
    assert.Equal(t, 10, services.ComputeLevel(4500))
}

func TestAwardPointsCapped(t *testing.T) {
    // Test daily cap enforcement
}

func TestBanEnforcement(t *testing.T) {
    // Test banned user cannot comment
}

Integration Tests (API):

# POST comment while banned → 403
curl -X POST /api/v1/comments \
  -H "Authorization: Bearer $BANNED_USER_TOKEN" \
  -d '{"target_type":"article","target_id":"1","content":"test"}' \
  → expect 403

# Redeem reward without enough points → 400
curl -X POST /api/v1/engagement/redeem \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"reward_id":1}' \
  → expect 400 if points < cost

Monitoring & Maintenance

Metrics to Track

Engagement:

• Daily active users earning points
• Average points earned per user
• Redemption rate (redeemed / earned)
• Most popular rewards
• Average level progression time
• Achievement unlock rate

Comments:

• Comments per day
• Spam score distribution
• Ban rate (bans / comments)
• Report rate
• Appeal approval rate
• Average comment length

Database Queries

Check System Health:

-- Total users with profiles
SELECT COUNT(*) FROM user_profiles;

-- Points earned today
SELECT SUM(delta) FROM points_transactions 
WHERE delta > 0 AND created_at > CURRENT_DATE;

-- Active bans
SELECT COUNT(*) FROM comment_bans 
WHERE until IS NULL OR until > NOW();

-- Pending redemptions
SELECT COUNT(*) FROM reward_redemptions 
WHERE status = 'pending';

-- High spam scores (potential issues)
SELECT COUNT(*) FROM comments 
WHERE spam_score > 0.7;

Maintenance Tasks

Daily:

• ✅ Review comment reports queue
• ✅ Check pending redemptions
• ✅ Monitor spam scores

Weekly:

• ✅ Review ban appeals
• ✅ Analyze points inflation
• ✅ Check for abuse patterns
• ✅ Update bad words dictionary if needed

Monthly:

• ✅ Audit top point earners
• ✅ Review reward popularity
• ✅ Clean expired bans
• ✅ Archive old transactions (optional)

Performance Optimization

If Slow Queries:

-- Add additional indexes
CREATE INDEX idx_comments_target_status ON comments(target_type, target_id, status);
CREATE INDEX idx_points_tx_reason_created ON points_transactions(reason, created_at DESC);

-- Analyze query plans
EXPLAIN ANALYZE SELECT * FROM comments WHERE target_type = 'article' AND status = 'visible';

If High Memory:

• Implement pagination everywhere
• Add LIMIT to unbounded queries
• Cache leaderboards (Redis)

Security Considerations

Authentication & Authorization

✅ JWT Auth on all protected endpoints
✅ Role checks for admin operations
✅ Owner checks for edit/delete
✅ CSRF protection for cookie auth

Input Validation

✅ Backend validation - Primary defense
✅ Frontend validation - UX improvement
✅ Database constraints - Last resort

Anti-Abuse

✅ Rate limiting - Prevent flooding
✅ Daily caps - Limit point farming
✅ Ban system - Remove bad actors
✅ Spam detection - Auto-filter junk

Data Protection

✅ Transactions - Atomic operations
✅ Foreign keys - Referential integrity
✅ Unique constraints - No duplicates
✅ Soft deletes - Preserve audit trail (where appropriate)

---

Known Limitations & Future Work

Current Limitations

1. No ML spam detection - Uses rule-based scoring
2. No image uploads in comments - Text only
3. Limited reaction types - 8 fixed options
4. No threaded UI - Comments shown flat
5. Manual reward fulfillment - No automation

Planned Enhancements

Phase 2 (Q1 2026):

• Notification system (mentions, replies)
• Rich text comments (links, formatting)
• Image attachments
• Seasonal events (double XP weekends)
• Profile badges

Phase 3 (Q2 2026):

• ML-based spam detection
• Automated reward delivery (webhooks)
• Team/guild system
• Trading/gifting points (?)
• Analytics dashboard

---

Support & Troubleshooting

Common Issues

Issue: User can't redeem reward
Solution: Check points balance, verify stock > 0, ensure reward active

Issue: Comment not visible
Solution: Check status (may be hidden), spam score > 0.5, user banned

Issue: Points not awarded
Solution: Check daily cap, verify action logged in transactions

Issue: Username already taken
Solution: Add suffix, suggest alternatives

Issue: Ban not enforced
Solution: Check until timestamp, verify ban record exists

Debug Commands

-- Check user profile
SELECT * FROM user_profiles WHERE user_id = 123;

-- Check active bans for user
SELECT * FROM comment_bans 
WHERE user_id = 123 AND (until IS NULL OR until > NOW());

-- Check recent transactions
SELECT * FROM points_transactions 
WHERE user_id = 123 ORDER BY created_at DESC LIMIT 10;

-- Check pending redemptions
SELECT r.*, ri.name, u.email 
FROM reward_redemptions r
JOIN reward_items ri ON r.reward_id = ri.id
JOIN users u ON r.user_id = u.id
WHERE status = 'pending';
