Verification Boundary

The suite exercises pure membership decisions against literal inputs and expected outputs.

What This Suite Proves

The structured bindings identify the capability and feature cases whose reviewed assertions this suite executes. Source anchors preserve the evidence for each binding.

What It Does Not Prove

A pure-rule pass does not prove persistence, permission enforcement through the API or a complete business lifecycle. Registration records existing code and leaves execution and conformance unverified.

Real Dependencies and Test Doubles

The decision functions and schemas are real. Literal inputs and checked-in fixtures supply their data; this boundary does not call live owners.

Must Not Be Doubled

Keep the decision function or schema under test real; replacing its result would remove the proof.
