Examples & Contracts ​

This section covers practical usage scripts and formal DSL contracts.

DSL Contracts (tests/contracts/dsl.contract.test.mjs) ​

Contract tests ensure DSL behavior remains stable:

• path write/read boot behavior
• fixed selectors ([1])
• broadcast ([i]) with derivations
• logical filters
• range and multi-select
• transform projections

Run:

npm run test:contracts

Demo Scripts ​

When to Use Demos vs Contracts ​

• Use demos to communicate capability and onboarding.
• Use contracts to lock behavior and catch regressions.
