+1. Wait for build to complete (check **Build logs** tab)
+2. Once "Running", test the endpoints:
+
+```bash
+# Health check
+curl https://YOUR_USERNAME-aletheionguard.hf.space/health
+
+# Predict (requires auth if Space is private)
+curl -X POST https://YOUR_USERNAME-aletheionguard.hf.space/predict \
+  -H "Authorization: Bearer hf_YOUR_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"text": "Paris is the capital of France"}'
+```
+
+Expected response:
+```json
+{
+  "q1": 0.06,
+  "q2": 0.08,
+  "height": 0.90,
+  "message": "Heuristic metrics computed successfully.",
+  "verdict": "ACCEPT"
+}
+```
+
+## 🔄 Step 6: Update Models (After Fine-tuning)
+
+After fine-tuning with `scripts/finetune_real_data.py`:
+
+```bash
+# Copy new models
+cp /home/sapo/AletheionGuard/models/real_finetuned/*.pth .
+cp /home/sapo/AletheionGuard/models/real_finetuned/q1q2-finetuned-*.ckpt q1q2_best.ckpt
+
+# Update metadata
+nano model_info.json  # Update training info and metrics
+
+# Commit and push
+git add *.pth *.ckpt model_info.json
+git commit -m "Update to fine-tuned models (TruthfulQA + SQuAD)"
+git push hf main
+```
+
+## 📊 Monitoring & Logs
+
+- **View logs**: Click **Logs** tab in your Space
+- **Restart Space**: Click **Factory reboot** if needed
+- **Monitor usage**: Check **Analytics** tab
+
+## 💰 Costs & Limits
+
+### Free Tier (CPU Basic)
+- ✅ Perfect for demos and low-traffic
+- ✅ Includes: 2 vCPU, 16 GB RAM
+- ❌ Limited to ~1000 requests/day
+- ❌ May sleep after inactivity
+
+### Paid Tier (Upgrade Options)
+- **CPU Upgrade** ($0.03/hour): 4 vCPU, 32 GB RAM
+- **GPU T4** ($0.60/hour): For faster inference
+- **Persistent**: Space never sleeps
+
+To upgrade:
+1. Go to Space → Settings → Hardware
+2. Select tier → Upgrade
+
+## 🔐 Using with BYO-HF Mode
+
+After deployment, use your Space with AletheionGuard:
+
+```python
+from aletheion_guard import EpistemicAuditor
+
+auditor = EpistemicAuditor(
+    mode="byo-hf",
+    hf_space_url="https://huggingface.co/spaces/YOUR_USERNAME/aletheionguard",
+    hf_token="hf_YOUR_TOKEN"  # Only if Space is private
+)
+
+result = auditor.evaluate("The Earth is flat")
+print(f"Verdict: {result.verdict}, Height: {result.height}")
+```
+
+## 🐛 Troubleshooting
+
+### Build Failed
+
+Check **Build logs** for errors. Common issues:
+
+1. **LFS bandwidth exceeded**: Use HuggingFace Pro ($9/month)
+2. **File too large**: Compress models or use smaller batch size during training
+3. **Docker build timeout**: Simplify Dockerfile or reduce dependencies
+
+### Space Not Starting
+
+1. Check **Logs** tab for runtime errors
+2. Verify `app.py` has no syntax errors
+3. Ensure all model files are present
+4. Try **Factory reboot**
+
+### Authentication Errors
+
+1. Ensure HF token has **Write** permissions
+2. For private Spaces, include token in requests
+3. Check token expiration
+
+### Slow Inference
+
+1. Upgrade to GPU hardware
+2. Optimize model (quantization, pruning)
+3. Use caching for repeated requests

+# 🔧 Fix Git LFS for HuggingFace Push
+
+O push falhou porque o Git LFS não está configurado. Siga estes passos:
+
+## Passo 1: Instalar Git LFS
+
+```bash
+# Para Ubuntu/Debian/WSL
+curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
+sudo apt-get install git-lfs
+
+# Verificar instalação
+git lfs version
+```
+
+## Passo 2: Configurar Git LFS no Repositório
+
+```bash
+cd /home/sapo/AletheionGuard/hf_space_example/AletheionGuard
+
+# Inicializar Git LFS
+git lfs install
+
+# Verificar que .gitattributes existe e tem as configurações corretas
+cat .gitattributes
+```
+
+## Passo 3: Resetar o Commit Anterior e Re-adicionar com LFS
+
+```bash
+# Voltar um commit (desfazer o commit que falhou no push)
+git reset --soft HEAD~1
+
+# Verificar arquivos que precisam de LFS
+ls -lh *.pth *.ckpt
+
+# Re-adicionar arquivos (agora com LFS)
+git add .gitattributes
+git add *.pth
+git add *.ckpt
+git add *.py
+git add *.md
+git add *.txt
+git add Dockerfile
+
+# Verificar que os arquivos grandes estão no LFS
+git lfs ls-files
+
+# Commit novamente
+git commit -m "Initial commit: AletheionGuard Space with Trial 012 models"
+```
+
+## Passo 4: Push para HuggingFace
+
+```bash
+# Push
+git push
+
+# Se pedir credenciais:
+# Username: gnai-creator
+# Password: seu token HF (hf_...)
+```
+
+## Verificar Arquivos LFS
+
+Após adicionar os arquivos, você deve ver algo assim:
+
+```bash
+$ git lfs ls-files
+c9a5b2e1f3 * base_forces.pth
+d4f8c7a2b1 * height_gate.pth
+e3d9b4f8c2 * q1_gate.pth
+f2e8a3d7c1 * q2_gate.pth
+a1b2c3d4e5 * q1q2_best.ckpt
+```
+
+## Solução Alternativa (Se Git LFS Não Funcionar)
+
+Se você não conseguir instalar o Git LFS, pode:
+
+1. **Remover os modelos grandes** e fazer upload manual depois:
+   ```bash
+   git rm --cached *.pth *.ckpt
+   git commit -m "Remove large files temporarily"
+   git push
+   ```
+
+2. **Upload manual pelo site**:
+   - Vá para https://huggingface.co/spaces/gnai-creator/AletheionGuard
+   - Clique em "Files" → "Upload files"
+   - Faça upload dos arquivos `.pth` e `.ckpt` manualmente
+
+3. **Ou use modelos menores/mock** para demonstração:
+   - Edite `app.py` para usar apenas heurísticas (já implementado como fallback)
+   - Remove a necessidade dos arquivos `.pth`
+
+## Comandos Úteis
+
+```bash
+# Ver status do LFS
+git lfs status
+
+# Ver arquivos rastreados pelo LFS
+git lfs ls-files
+
+# Ver tamanho dos arquivos
+du -sh *.pth *.ckpt
+
+# Limpar cache LFS se necessário
+git lfs prune
+```
+
+## Problema Comum: "last.ckpt"
+
+O arquivo `last.ckpt` não deveria estar no repositório. Para removê-lo:
+
+```bash
+# Se ele foi adicionado por engano
+git rm last.ckpt
+git commit -m "Remove last.ckpt"
+```
+

+
+**Depois de seguir estes passos, tente o push novamente!** 🚀

+# 🛡️ AletheionGuard - Epistemic Auditor for LLMs
+
+**AletheionGuard** is a cutting-edge epistemic uncertainty quantification system for Large Language Models (LLMs). It helps detect when AI models are confident vs. uncertain, reducing hallucinations and improving reliability.
+
+## 🎯 What is AletheionGuard?
+
+AletheionGuard audits LLM outputs by quantifying two types of uncertainty:
+
+- **Q1 (Aleatoric)**: Inherent randomness in the data
+- **Q2 (Epistemic)**: Model's lack of knowledge/confidence
+
+From Q1 and Q2, we compute a **Height** score (confidence) using the pyramidal formula:
+
+```
+height = 1 - √(Q1² + Q2²)
+```
+
+Based on the height, we provide a **Verdict**:
+- **ACCEPT** (height ≥ 0.85): High confidence
+- **MAYBE** (0.70 ≤ height < 0.85): Moderate confidence
+- **REFUSED** (height < 0.70): Low confidence, likely hallucination
+
+## 🚀 Quick Start
+
+### Option 1: Use Our Public API
+
+```python
+import requests
+
+response = requests.post(
+    "https://api.aletheion.com/v1/audit",
+    headers={"Authorization": "Bearer ag_your_api_key"},
+    json={"text": "The Earth is flat"}
+)
+
+result = response.json()
+print(f"Verdict: {result['verdict']}")
+print(f"Q1: {result['q1']}, Q2: {result['q2']}, Height: {result['height']}")
+```
+
+Get your API key at: https://aletheion.com/signup
+
+### Option 2: Deploy Your Own HF Space (BYO-HF Mode)
+
+1. Click "Duplicate this Space" in HuggingFace
+2. Set your Space to **PRIVATE**
+3. Note your Space URL and HF token
+4. Use with AletheionGuard client:
+
+```python
+from aletheion_guard import EpistemicAuditor
+
+auditor = EpistemicAuditor(
+    mode="byo-hf",
+    hf_space_url="https://huggingface.co/spaces/YOUR_USERNAME/YOUR_SPACE",
+    hf_token="hf_your_token"
+)
+
+result = auditor.evaluate("Paris is the capital of France")
+print(f"Verdict: {result.verdict}, Height: {result.height}")
+```
+
+### Option 3: Self-Hosted
+
+Download models and run locally:
+
+```python
+from aletheion_guard import EpistemicAuditor
+
+auditor = EpistemicAuditor(
+    mode="local",
+    model_path="./models"
+)
+
+result = auditor.evaluate("Quantum entanglement is spooky")
+```
+
+## 📦 Model Files
+
+This Space includes pre-trained models from **Trial 012**:

+See `model_info.json` for detailed metadata.
+
+## 🏗️ Architecture
+
+AletheionGuard uses a **Pyramidal Multi-Gate Architecture**:
+
+1. **Embedding**: Text → `all-MiniLM-L6-v2` (384 dims)
+2. **Q1 Gate**: MLP (384 → 256 → 128 → 64 → 1) for aleatoric uncertainty
+3. **Q2 Gate**: MLP (384 → 256 → 128 → 64 → 1) for epistemic uncertainty
+4. **Height Gate**: MLP (386 → 128 → 64 → 1) for combined confidence
+5. **Base Forces**: Learnable embeddings for calibration
+
+**Total parameters**: ~580,000 (2.3 MB)
+**Inference time**: <50ms per request (CPU)
+
+## 📊 Performance Metrics
+
+**On Synthetic Test Set** (1,590 samples):
+- Q1 MSE: 0.0501
+- Q2 MSE: 0.0499
+- RCE (Relative Calibration Error): 0.0415
+- Height MSE: 0.0521
+
+**Expected after fine-tuning** on real data (TruthfulQA + SQuAD v2):
+- Q1 MSE: ~0.042-0.045 (10-15% improvement)
+- Q2 MSE: ~0.040-0.043
+- RCE: ~0.035-0.038
+
+## 🔬 Research & Academic Use
+
+AletheionGuard implements techniques from:
+- **Epistemic Uncertainty Quantification** in deep learning
+- **Pyramidal Framework** for multi-dimensional uncertainty
+- **Calibration Theory** for reliable confidence scores

+
+## 🛠️ API Endpoints
+
+This Space provides a minimal FastAPI endpoint for BYO-HF mode:
+
+- `GET /`: Health check
+- `POST /predict`: Predict uncertainties for text
+  - Input: `{"text": "...", "context": "..."}`
+  - Output: `{"q1": 0.xx, "q2": 0.xx, "height": 0.xx, "verdict": "..."}`
+- `GET /health`: Health check
+
+See `app.py` for implementation details.
+
+## 📝 Notes
+
+1. **MVP Status**: These models were trained on **synthetic data** and are suitable for demos and MVPs.
+2. **Production Readiness**: For production use, fine-tune on real datasets like TruthfulQA and SQuAD v2.
+3. **Fine-tuning Script**: Use `scripts/finetune_real_data.py` in the main repository.
+4. **HuggingFace Pro**: For high-volume production use, consider HuggingFace Pro ($9/month) or dedicated inference endpoints.
+
+## 🔐 Security & Privacy
+
+- **BYO-HF Mode**: Run in your own private HF Space - we never see your data
+- **Self-Hosted**: Run completely on-premises for maximum privacy
+- **Public API**: Uses industry-standard encryption and data retention policies
