Test Result

Question: "John 3:16"

Response:

For God so loved the world, that he gave his only begotten Son, that whosoever
believeth on him should not perish, but have eternal life. [ASV] John 3:16

This verse highlights God's immense love for humanity and His willingness to
sacrifice His Son, Jesus Christ, to offer salvation and eternal life to all who
believe. It is a reminder of the depth of God's grace and the hope found in Christ.

Problems Fixed

1. Ollama Conflict ❌→✅

Problem:

• Ollama was running with nomic-embed-text model
• Generated 768-dimension embeddings instead of 1536
• Caused "different vector dimensions" error

Solution:

• Disabled OLLAMA_API_URL in .env.local
• Stopped Ollama service: systemctl disable ollama
• Killed all Ollama processes
• Now only using Azure OpenAI embeddings (1536-dim)

2. Build Crashes Server ❌→✅

Problem:

• Next.js build consumed 4-6GB RAM
• No swap configured (SwapTotal: 0)
• Linux OOM killer crashed production server

Solution:

• ✅ Created scripts/safe-build.sh with guardrails:
  • Checks available memory (needs 4GB minimum)
  • Stops PM2 during build to free memory
  • Sets Node.js memory limit (4GB max)
  • Monitors memory usage (kills if >90%)
  • Restarts services after build
• ✅ Added 8GB swap memory for safety
• ✅ Documented in BUILD_GUIDE.md

3. Missing Table Columns ❌→✅

Problem:

• Vector search expected ref column (doesn't exist)
• Hybrid search expected tsv column (doesn't exist)

Solution:

• Generate ref column on-the-fly: book || ' ' || chapter || ':' || verse
• Removed text search (TSV) - using pure vector search
• Simplified queries to work with actual schema

4. Azure Content Filter ⚠️→✅

Problem:

• Azure OpenAI filtered some Bible verses as "protected_material_text"
• Triggered fallback error message

Solution:

• Using shorter, focused prompts
• Avoiding sending too many verses at once
• Content filter triggered less frequently now

Build & Deployment

⚠️ ALWAYS Use Safe Build Script

# CORRECT - Safe build with guardrails
bash scripts/safe-build.sh

# WRONG - Can crash server
npm run build  ❌ NEVER USE THIS

Safe Build Features

1. ✅ Checks 4GB+ free memory required
2. ✅ Stops PM2 to free ~500MB-1GB
3. ✅ Clears build cache
4. ✅ Limits Node.js to 4GB max
5. ✅ Monitors memory during build
6. ✅ Kills build if memory >90%
7. ✅ Verifies build artifacts
8. ✅ Restarts PM2 services
9. ✅ Reports memory usage

Build Output Example

========================================
   Safe Next.js Build Script
========================================

Available Memory: 14684 MB

Testing the AI Chat

Via Scripts

# Quick test
bash scripts/simple-chat-test.sh

# Full test suite
python3 scripts/test-ai-chat-complete.py

Via Frontend

1. Navigate to https://biblical-guide.com
2. Login or register
3. Go to AI Chat section
4. Ask: "What does the Bible say about love?"
5. Should receive response citing [ASV] or [RVA 1909]

Expected Response Format

The Bible speaks extensively about love...

[ASV] 1 Corinthians 13:4-7: "Love suffereth long, and is kind..."
[ASV] John 3:16: "For God so loved the world..."

This shows us that...

Troubleshooting

Issue: "different vector dimensions" error

Cause: Ollama is still running Fix:

systemctl stop ollama
systemctl disable ollama
pkill -9 ollama
pm2 restart biblical-guide

Issue: Build crashes server

Cause: Not using safe build script Fix:

# Always use:
bash scripts/safe-build.sh

# Never use:
npm run build  ❌

Issue: No verses found

Cause: Table name mismatch Fix: Check lib/vector-search.ts line 20-24 for table whitelist

Issue: Azure content filter

Cause: Too many verses or copyrighted content Fix: Reduce verse limit in app/api/chat/route.ts line 190

Priority 2: Improve Citations

• Show multiple versions side-by-side
• Add verse numbers to responses
• Include chapter context

Priority 3: Performance

• Cache frequent queries (Redis)
• Pre-compute popular topics
• Add rate limiting
