To enforce exact signature matching for Pact interfaces, define signature-only members using defun, defcap, and defconst, then validate implementations with strict implements checks to ensure cross-module compatibility and immutability.

Defining interface contracts in Pact for governance boundaries involves creating signature-only interfaces and using governance-oriented patterns to version and extend them without breaking upgrades across modules.

Validating cross-module implementations of a Pact contract requires using strict implements checks and immutability rules to verify that the implementing module matches every interface signature exactly.

Yes, you can version and extend Pact interfaces without breaking implementations by applying governance-oriented patterns that support interface immutability and safe upgrades across module boundaries.

Yes, a Pact interface definition requires YAML frontmatter containing a name and description to ensure metadata is consistently implemented and verifiable across governance boundaries.
