# Overview

> Concepts and API-reference source for Helix.

Helix is a high-precision sensitive-content decision engine for ambiguity-heavy
cases.

The product output is a decision: `escalate`, `suppress`, or `abstain`. Labels,
scores, and evidence are inputs to that decision; they are not the product.

## What these docs cover

* The decision-first model behind Helix.
* How evidence, confounders, uncertainty, and abstention fit together.
* Public API-reference material once the runtime contract is stable enough to
  publish.

## Current scope

These docs are intentionally narrow. They are public product documentation, not
private planning canon. Canonical strategy, architecture, evaluation, and
runtime-contract decisions remain in the Helix Alpha hub until they are approved
for public projection here.
