+# Expected output:
+# NAME                    ID              SIZE      MODIFIED
+# gemma4:e2b              <hash>          2.4 GB    <timestamp>
+# nomic-embed-text        <hash>          274 MB    <timestamp>
+
+# 4. Test model inference (quick test)
+ollama run gemma4:e2b "Hello, test response"
+# Expected: Gemma4 generates text response within 5-10s
+
+# 5. Test embedding model
+ollama run nomic-embed-text "test text"
+# Expected: Returns 768-dimensional vector
+```
+
+**Installation Commands (if missing):**
+
+```bash
+# Install Ollama (Windows)
+# Download from: https://ollama.com/download/windows
+
+# Pull models
+ollama pull gemma4:e2b
+ollama pull nomic-embed-text
+
+# Verify VRAM usage during inference
+nvidia-smi --query-gpu=memory.used --format=csv,noheader
+# Expected: < 5120 MB (5GB threshold per SC-003)
+```
+
+**Troubleshooting:**
+- **Ollama not responding**: Check if Ollama service is running (`services.msc` on Windows)
+- **GPU not detected**: Verify NVIDIA driver and CUDA installation
+- **Model pull fails**: Check internet connection and proxy settings
+- **VRAM overflow**: Reduce concurrent jobs (BullMQ concurrency=1 enforced)
+
+---
+
+### 2. Qdrant Vector Database (Semantic Search)
+
+**Requirements:**
+- **Version**: Qdrant ≥ 1.7.0
+- **Storage**: ≥ 10GB free space (for ~20,000 docs × 768-dim vectors)

+- **Collection**: `lcbp3_documents` (auto-created on first use)
+
+**Verification Steps:**
+
+```bash
+# 1. Check Qdrant health
+curl http://192.168.10.XX:6333/health
+# Expected: {"status":"ok"}
+
+# 2. Check collections (if already created)
+curl http://192.168.10.XX:6333/collections
+# Expected: {"result":{"collections":[...]}} or empty array
+
+# 3. Verify Qdrant metrics (optional)
+curl http://192.168.10.XX:6333/metrics
+# Expected: Prometheus metrics output
+```
+
+**Installation Commands (Docker - recommended):**
+
+```bash
+# Run Qdrant container (QNAP or ASUSTOR)
+docker run -d \
+  --name qdrant \
+  -p 6333:6333 \
+  -p 6334:6334 \
+  -v $(pwd)/qdrant_storage:/qdrant/storage \
+  qdrant/qdrant:v1.7.0
+
+# Or use docker-compose (add to existing compose file)
+# See: specs/04-Infrastructure-OPS/04-00-docker-compose/
+```
+
+**Troubleshooting:**
+- **Connection refused**: Check if Qdrant container is running (`docker ps`)
+- **Port conflict**: Ensure port 6333 is not used by other services
+- **Storage errors**: Verify disk space and permissions on mounted volume
+- **Network issues**: Check firewall rules allow traffic on port 6333
+
+---
+
+### 3. Redis 7 (BullMQ Queue Backend)
+
+**Requirements:**
+- **Version**: Redis ≥ 7.0.0
+- **Persistence**: AOF enabled (recommended for job durability)
+- **Memory**: ≥ 2GB (for job queue storage)
+- **Network**: Accessible from backend container (`redis://REDIS_HOST:6379`)
+
+**Verification Steps:**
+
+```bash
+# 1. Check Redis version
+redis-cli -h 192.168.10.XX -p 6379 INFO server | grep redis_version
+# Expected: redis_version=7.x.x
+
+# 2. Check Redis health
+redis-cli -h 192.168.10.XX -p 6379 PING
+# Expected: PONG
+
+# 3. Check existing queues (if any)
+redis-cli -h 192.168.10.XX -p 6379 KEYS "bull:*"
+# Expected: May show existing BullMQ queues from other modules
+
+# 4. Check memory usage
+redis-cli -h 192.168.10.XX -p 6379 INFO memory | grep used_memory_human
+# Expected: used_memory_human:<value> (monitor for growth)
+```
+
+**Configuration Notes:**
+- Use existing Redis instance from BullMQ setup (ADR-008)
+- No additional configuration needed for 2-queue setup
+- Queue names: `ai-realtime` and `ai-batch` (auto-created by BullMQ)
+
+**Troubleshooting:**
+- **Connection timeout**: Check Redis service status and network connectivity
+- **Memory overflow**: Monitor Redis memory usage, enable maxmemory policy if needed
+- **Queue not created**: Check BullMQ configuration in `backend/src/config/bullmq.config.ts`
+
+---
+
+### 4. Backend Dependencies (NestJS + AI Libraries)
+
+**Requirements:**
+- **Node.js**: ≥ 18.x (LTS)
+- **npm/pnpm**: Latest version
+- **TypeScript**: ≥ 5.x
+
+**Required Packages:**
+
+```bash

+# Check installed packages
+npm ls @qdrant/js-client-rest
+# Expected: @qdrant/js-client-rest@1.x.x
+
+# Check other AI-related packages
+npm ls bullmq ioredis
+# Expected: bullmq@5.x.x, ioredis@5.x.x
+
+# Install missing packages (if any)
+npm install @qdrant/js-client-rest
+npm install bullmq ioredis --save
+```
+
+**Verification Steps:**
+
+```bash
+# 1. Check package.json
+cat package.json | grep -A 5 "dependencies"
+# Expected: Should include @qdrant/js-client-rest, bullmq, ioredis
+
+# 2. Verify TypeScript compilation
+npm run build
+# Expected: No compilation errors
+
+# 3. Check environment variables
+cat .env | grep -E "OLLAMA|QDRANT|OCR|REDIS"
+# Expected: All AI-related variables set (see Environment Variables section)
+```
+
+**Troubleshooting:**
+- **Package not found**: Run `npm install` to restore dependencies
+- **TypeScript errors**: Check tsconfig.json and type definitions
+- **Env variables missing**: Copy from `.env.example` and configure
+
+---
+
+### 5. PaddleOCR Sidecar (OCR Engine)
+
+**Requirements:**
+- **Python**: ≥ 3.8
+- **PaddlePaddle**: ≥ 2.5.0
+- **PaddleOCR**: ≥ 2.7.0
+- **API Server**: HTTP endpoint on port 8765 (default)
+
+**Verification Steps:**

+curl http://localhost:8765/health
+# Expected: {"status":"ok"} or similar
+
+# 2. Test OCR on sample image
+curl -X POST http://localhost:8765/ocr \
+  -F "image=@sample.png" \
+  -F "lang=th"
+# Expected: JSON with extracted text
+
+# 3. Check OCR character threshold setting
+# (Backend env var: OCR_CHAR_THRESHOLD=100)
+# This determines when to use PaddleOCR vs PyMuPDF
+```
+
+**Installation Commands (if not already set up):**
+
+```bash
+# Install PaddleOCR (Python)
+pip install paddleocr paddlepaddle
+
+# Run OCR API server (example)
+python -m paddleocr.serve --port 8765
+```
+
+**Troubleshooting:**
+- **API not responding**: Check if PaddleOCR server is running
+- **OCR fails on Thai text**: Verify Thai language model is installed
+- **Slow performance**: Consider GPU acceleration for PaddleOCR
+
+---
+
+### 6. Network Configuration & Firewall
+
+**Requirements:**
+- **Desk-5439 (Ollama)**: Port 11434 accessible from backend
+- **Qdrant Server**: Port 6333 accessible from backend
+- **Redis Server**: Port 6379 accessible from backend
+- **PaddleOCR**: Port 8765 accessible from backend (if sidecar on same host)
+
+**Verification Steps:**
+
+```bash
+# Test connectivity from backend container
+# (Run these commands inside backend container or from backend host)
+
+# 1. Test Ollama
+curl http://192.168.10.XX:11434/api/tags
+# Expected: JSON with model list
+
+# 2. Test Qdrant
+curl http://192.168.10.XX:6333/health
+# Expected: {"status":"ok"}
+
+# 3. Test Redis
+redis-cli -h 192.168.10.XX -p 6379 PING
+# Expected: PONG
+
+# 4. Test PaddleOCR (if on separate host)
+curl http://192.168.10.XX:8765/health
+# Expected: {"status":"ok"}
+```
+
+**Troubleshooting:**
+- **Connection timeout**: Check firewall rules on target hosts
+- **DNS resolution issues**: Use IP addresses instead of hostnames
+- **VPN/Network segmentation**: Ensure backend can reach AI infrastructure network
+
+---
+
+### 7. GPU Resource Monitoring (Critical for SC-003)
+
+**Requirements:**
+- **VRAM Limit**: ≤ 5GB peak (per SC-003)
+- **Concurrency**: 1 job per queue (enforced by BullMQ)
+
+**Verification Commands:**
+
+```bash
+# Monitor VRAM in real-time
+watch -n 1 nvidia-smi --query-gpu=memory.used --format=csv,noheader
+
+# Check GPU utilization during job execution
+nvidia-smi dmon -s u
+
+# Log VRAM usage to file (for analysis)
+nvidia-smi --query-gpu=timestamp,memory.used,utilization.gpu \
+  --format=csv -l 1 > gpu_usage.log
+```
+
+**Expected Behavior:**
+- **ai-batch job**: VRAM peaks at ~2.5GB (gemma4:e2b Q4_K_M)
+- **ai-realtime job**: VRAM peaks at ~2.5GB (same model)
+- **No concurrent jobs**: ai-batch pauses when ai-realtime active (GPU protection)
+
+**Troubleshooting:**
+- **VRAM overflow (>5GB)**: Reduce model quantization or increase GPU memory
+- **GPU contention**: Verify BullMQ concurrency=1 enforcement
+- **Slow inference**: Check GPU utilization, consider faster model quantization
