The Gym — negotiate against an AI with a secret bottom line

🔒 Your key stays in this browser. The counterparty's bottom line is generated fresh each session and hidden until the debrief.

The Defense asks you questions. The Gym plays against you with secrets: your counterparty has a hidden bottom line, hidden pressures, and a concession style you'll have to read from behaviour. Close the deal (or walk), and only then does the debrief reveal what was actually achievable — and score you against it.
