+# CCPA Compliance Analyzer — OPEN HACK 2026
+
+## Solution Overview
+
+This system analyzes natural-language business practice descriptions and determines whether they violate the California Consumer Privacy Act (CCPA). It uses a **RAG (Retrieval-Augmented Generation)** architecture:
+
+1. **Knowledge Base**: The full CCPA statute (key sections 1798.100–1798.135) is pre-encoded as structured text in `ccpa_knowledge.py`, covering all major consumer rights and business obligations.
+2. **LLM Inference**: [Llama 3.2 3B](https://ollama.com/library/llama3.2) (via Ollama) receives a system prompt containing the CCPA statute context + the user's business practice prompt and returns a JSON classification.
+3. **Rule-Based Fallback**: A deterministic keyword/pattern matcher provides a reliable backup if the LLM is unavailable or returns unparseable output.
+4. **FastAPI Server**: Exposes `GET /health` and `POST /analyze` endpoints on port 8000.
+
+**Pipeline**: `POST /analyze` → LLM (Llama 3.2 3B via Ollama) with CCPA context → JSON parse → logic validation → `{"harmful": bool, "articles": [...]}`
+
+---
+
+## Docker Run Command
+
+```bash
+docker run --gpus all -p 8000:8000 -e HF_TOKEN=xxx yourusername/ccpa-compliance:latest
+```
+
+Without GPU (CPU-only mode, slower):
+```bash
+docker run -p 8000:8000 yourusername/ccpa-compliance:latest
+```
+
+---
+
+## Environment Variables
+
+| Variable | Required | Description |
+|---|---|---|
+| `HF_TOKEN` | No | Hugging Face access token (not needed for llama3.2 via Ollama) |
+| `MODEL_NAME` | No | Ollama model to use (default: `llama3.2:3b`) |
+| `OLLAMA_HOST` | No | Ollama server URL (default: `http://localhost:11434`) |
+
+---
+
+## GPU Requirements
+
+- **Recommended**: NVIDIA GPU with ≥4GB VRAM (RTX 3060 or better)
+- **CPU-only fallback**: Supported, but inference will be significantly slower (~30-60s per request). The 120s timeout in the test script provides sufficient buffer.
+- **Model size**: llama3.2:3b is ~2GB on disk, ~2GB VRAM when loaded
+
+---
+
+## Local Setup Instructions (Fallback — no Docker)
+
+> Use only if Docker fails. Manual deployment incurs a score penalty.
+
+**Requirements**: Linux, Python 3.11+, [Ollama](https://ollama.com)
+
+```bash
+# 1. Install Ollama
+curl -fsSL https://ollama.com/install.sh | sh
+
+# 2. Start Ollama and pull model
+ollama serve &
+ollama pull llama3.2:3b
+
+# 3. Install Python dependencies
+pip install fastapi uvicorn httpx pydantic
+
+# 4. Run the FastAPI server
+cd /path/to/ccpa_project
+uvicorn app:app --host 0.0.0.0 --port 8000
+
+# 5. Verify it's running
+curl http://localhost:8000/health
+```
+
+---
+
+## API Usage Examples
+
+### Health Check
+```bash
+curl http://localhost:8000/health
+# Response: {"status": "ok"}
+```
+
+### Analyze — Violation Detected
+```bash
+curl -X POST http://localhost:8000/analyze \
+  -H "Content-Type: application/json" \
+  -d '{"prompt": "We are selling our customers personal information to data brokers without giving them a chance to opt out."}'
+
+# Response:
+# {"harmful": true, "articles": ["Section 1798.120", "Section 1798.100"]}
+```
+
+### Analyze — No Violation
+```bash
+curl -X POST http://localhost:8000/analyze \
+  -H "Content-Type: application/json" \
+  -d '{"prompt": "We provide a clear privacy policy and allow customers to opt out of data selling at any time."}'
+
+# Response:
+# {"harmful": false, "articles": []}
+```
+
+### Using docker-compose (with organizer test script)
+```bash
+docker compose up -d
+python validate_format.py
+docker compose down
+```
+
+---

+
+## Notes on Accuracy
+
+- The system cites sections based on CCPA statute analysis, not keyword matching alone.
+- The LLM is instructed to identify **all** violated sections, not just the most obvious one.
+- The rule-based fallback provides reliable detection for common violation patterns.
+- Incorrect article citations result in zero marks per the scoring rubric, so the system is conservative: it only cites a section when there is clear evidence of a violation matching that section's specific requirements.
