"""Harness smoke test (AC-1).

The only AZ-406 test that runs inside the e2e-runner docker image. It
asserts the harness is wired correctly without depending on any of the
fixtures owned by AZ-407+ (no frame replay, no SITL contract checks).

What it verifies:
    1. pytest discovers tests under `/test-suite`.
    2. The CSV reporter plugin is loaded.
    3. The parametrize matrix produces at least one variant.
    4. The `attach_evidence` fixture is reachable.

Per-scenario tests (FT-P-01 onward) will land under their own files in
this directory.
