Pure checks for Ai Usage Format

Verification Boundary

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

What This Suite Proves

HQ cost formatting pairs dollars and credits. 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

The console formatters are real. Literal costs, states and dates supply their inputs; no browser or service is involved.

Must Not Be Doubled

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