Script API

Shared leaf contracts for TypeScript-authored Integration functions and Automation scripts. This crate defines immutable resource references, build-generated Automation contracts, artifact metadata and internal outcomes. It does not load code, grant permissions, implement host IO or execute scripts.

The JavaScript script contract is authoritative for the new execution boundary. The fixture corpus under fixtures/ is shared with consumer implementations. Models must be validated after deserialization and before use. Validation is not authorization or digest verification.

The new protocol is under migration. Existing Core and Lion consumers still use the old Wasm paths until their separate cutover; this crate does not make JavaScript execution available by itself.
