📜 Contracts

Contracts are the hard rules of the Lab’s interfaces.

If a contract exists, it means:

• systems rely on it
• agents should follow it
• changes require intention and documentation

What belongs here

• Field definitions that must remain stable (card_style, status, etc.)
• Resolution order / precedence rules
• “This affects display only” vs “this changes ownership” boundaries
• Backward compatibility notes

Start here

• Card Style Contract — defines card_style as a presentation-only override and how it resolves.
