we write code, test it, and only ship what passes.

The Foundry is a code-writing system that doesn't ship code until it's been tested. You give it a spec. It writes code. It runs tests against the code. If tests fail, it fixes the code and tests again. Only code that passes the gate gets shipped.

Why this matters: code that hasn't been tested is a guess. It breaks in production. It costs you time and money to fix. Test-proven code means you're shipping something that actually works.

How it helps: you write a spec. The Foundry handles the rest, writing, testing, gating. You get back code that's been verified. No surprises in production. No late-night fixes.

This is the capstone of a six-month build. The Foundry runs a full pipeline: planner writes a task DAG, coder writes code across multiple seats, tester runs the code in a sandbox, reviewer gates the diff. Every step is automated. Only proven code ships.
