| # Agentic Reliability Framework (ARF) – Technical Overview |
|
|
| > 🔒 **The core ARF engine is access‑controlled and not open source.** |
| > Available to qualified pilots under outcome‑based pricing. |
| > The **public specification** and **demo UI** are Apache 2.0. |

|
| ## 🧠 Core Engine (Protected) |
|
|
| ### Bayesian Risk Fusion |
|
|
| Conjugate Beta priors (online) + HMC logistic regression (offline) + optional hierarchical hyperpriors. |
|
|
| $$ |
| \text{risk} = w_{\text{conj}}\cdot\frac{\alpha}{\alpha+\beta} \;+\; w_{\text{hmc}}\cdot p_{\text{hmc}} \;+\; w_{\text{hyper}}\cdot \mu_{\text{hyper}} |
| $$ |
| |
| Weights are dynamic: |
| |
| $$ |
| w_{\text{hmc}} = \min\left(0.6,\; \frac{n}{n_0}\right), \qquad |
| w_{\text{hyper}} = \min\left(0.3,\; \text{base}\cdot(1-w_{\text{hmc}})\right) |
| $$ |
| |
| Posterior variance → 90% HDI for uncertainty quantification. |
| |
| ### Expected Loss Minimisation |
| |
| Chooses `APPROVE`, `DENY`, or `ESCALATE` by minimising: |
| |
| $$ |
| \begin{aligned} |
| L_{\text{approve}} &= \text{COST\_FP}\cdot R + \text{COST\_IMPACT}\cdot b_{\text{mean}} + \dots \\ |
| L_{\text{deny}} &= \text{COST\_FN}\cdot(1-R) + \text{COST\_OPP}\cdot v_{\text{mean}} \\ |
| L_{\text{escalate}} &= \text{COST\_REVIEW} + \text{COST\_UNCERTAINTY}\cdot\psi |
| \end{aligned} |
| $$ |
|
|
| ### Execution Ladder (Rust) |
|
|
| Mechanical gates: `license`, `confidence`, `risk`, `rollback`, `causal`. |
|
|
| ### Lyapunov Stability |
|
|
| Quadratic candidate $V(x,r) = \alpha r^2 + \beta\|x - x_{\text{des}}\|^2$ ensures healing actions converge. |
| |
| ### Cryptographic Signing |
| |
| Ed25519 signatures for `HealingIntent` (Python `cryptography`, Rust `ed25519_dalek`). |
