When a thread is created with a contract, Threadify uses that contract to validate record steps and identifies violations, failed business logic, race conditions, etc.

​
Starting with a Contract

Start a thread with a contract to enable automatic validation: 
// Use latest version (recommended)
const thread = await threadify.start('order_fulfillment', 'merchant');

// Use specific version
const thread = await threadify.start('order_fulfillment:2', 'merchant');

​
What Contracts Validate

Entry points - The first step must be a valid entry point defined in the contract. Transitions - Steps must follow the allowed transitions defined in the contract. Required fields - Context provided with each step must include all required fields. Terminal states - Threads automatically complete when reaching a terminal node.
Violations are reported via notifications but don’t block execution. Learn how to subscribe to violations.
