# How It Works

> High-level architecture overview

## Architecture

LiveOps separates **when** to intervene from **what** to do:

    E --> I[Normal Processing]

```

## Core Principles

**Pure evaluation** — The engine returns decisions, never performs I/O. Your middleware executes the effects.

**Fail-open** — Errors in patch evaluation allow the request through. Never blocks production traffic due to policy bugs.

**Deterministic** — Same input always produces same output. Fully testable before deployment.

## Integration Points

LiveOps embeds as a library with hooks at key points:

* HTTP request/response
* gRPC unary/streaming
* Downstream service calls
* Custom domain-specific hooks
