# Intelligence layer overview

> The guard rails and decision aids that turn your data into safe, policy-aligned plans.

The **intelligence layer** sits between your data and your actions. It encodes your
business policies as **rules**, supplies the limits those rules check against
(budgets, size curves, supplier constraints…), and provides AI decision aids
(recommendations, simulation, forecasts).

Here's how intelligence flows from data to action:

    end

    subgraph IL["Intelligence Layer"]

    end

        Alerts["Alerts<br/>(risk signals)"]
        Workflows["Workflows<br/>(automation)"]
    end

## How it connects

When you act on a plan, the rules from its **ruleset** are evaluated against live data —
much of which is supplied by the other intelligence-layer features (budget consumption,
size-curve deviation, supplier MOQ…). Rules can **block**, **warn**, or **log**, and
some plans route through an **approval** when a value threshold is crossed. See
[Inventory plans → lifecycle](/en/inventory-plans/lifecycle).

The same building blocks also shape **AI recommendations**: Solya's decision layer reads
your rules and the precomputed decision data to propose quantities and discounts you can
review before committing.
