"""Test suite for the benchmark instruments themselves.

A benchmark that measures with untested instruments cannot make accuracy

claims. These tests pin the measurement primitives: stream parsing per

adapter (golden fixtures), token accounting, the command-semantics contract,

the row contract, oracles, and calibration math.

Run from the repository root:

    python3 -m unittest discover -s tests -v
