## README

# @x12i/graphenix-logic

Runtime logic utilities for Graphenix graph execution: path resolution, variable assignment, and condition evaluation.

## Install

```bash
npm install @x12i/graphenix-logic@^2.16.0
```

## Usage

```ts
import { LogicEngine } from "@x12i/graphenix-logic";

const context = {
  state: { answer: 42 },
  variables: { count: 1 },
  history: [],
  outputs: { byKey: {}, byNodeId: {} },
  nodeStatus: {}
};

LogicEngine.resolveValue("$state.answer", context.state, context);
LogicEngine.applyAssignment(
  { name: "count", operation: "increment" },
  context.state,
  context
);
```

## API

| Export | Description |
|--------|-------------|
| `LogicEngine` | Static methods: `resolveValue`, `applyAssignment`, `evaluateCondition` |
| `ExecutionContext` | Runtime context shape (`state`, `variables`, `memory`, `node`, …) |
| `VariableAssignment` | Variable mutation descriptor |
| `Condition` | Simple/complex/function condition for `evaluateCondition` |

Ported from legacy `@x12i/graphenix@2.5.0` planner logic module for the 2.16 format train.
