Pure checks for Usage Features

Verification Boundary

The suite checks deterministic module behavior and declared configuration using local inputs.

What This Suite Proves

Every declared feature has readable descriptions. Combined bindings require every named suite; a component assertion alone does not establish the full experiment.

What It Does Not Prove

These checks do not establish database transactions, deployed permissions, provider availability or a complete user journey.

Real Dependencies and Test Doubles

PostgreSQL, production composite reads, workspace lookup and scoped execution contexts are real. A fixed clock selects windows; the queries and row policy are not doubled.

Must Not Be Doubled

Retain the function, configuration or boundary guard under test and its assertions; replacing them removes the evidence.
