Why SourceA

The problem

Most AI asks you to trust it.

Agents say "done" without proof. They drift. They can't be audited. You can't ship — or sell, or pass an audit — on what you can't verify. SourceA is the controlled runtime that refuses to ship until it passes — and hands you the receipt.

What SourceA is

A controlled runtime — not a chatbot.

An LLM only proposes a plan. A contract decides what's allowed. Work executes deterministically. A validator verifies it. Every run commits a receipt — output, evidence, and decision — that you can replay and audit.
