**Open‑source advisory engine for cloud infrastructure governance.**  
ARF provides **provably safe, mathematically grounded recommendations**—approve, deny, or escalate—when users request provisioning, configuration, or access changes.

---

## 🔍 What We Do

- **Bayesian Online Learning** – Fast, conjugate updates for per‑category risk using beta‑binomial models.
- **Offline Pattern Discovery** – Hamiltonian Monte Carlo (HMC/NUTS) logistic regression captures complex interactions (time‑of‑day, user role, environment).
- **Composable Policy Algebra** – Build fine‑grained rules with AND/OR/NOT combinators.
- **Semantic Memory** – FAISS‑based retrieval of similar past incidents for context‑aware decisions.
- **Deterministic Probability Thresholds (DPT)** – Clear approve/deny/escalate decisions based on calibrated failure probabilities.

## 📊 Key Mathematical Insights

| Concept | Implementation |
|--------|----------------|
| **Conjugate Priors** | Per‑category Beta priors, updated online with outcomes. |
| **HMC Sampling** | Logistic regression with NUTS, serialized to JSON for hot‑loading. |
| **Risk Fusion** | Dynamic weighted combination of conjugate, hyperprior, and HMC estimates. |
| **DPT** | `Approve` if P(failure) < 0.2; `Deny` if > 0.8; otherwise `Escalate`. |
