# meta-fixture-card

fixture: the card pins v1 and ADMISSION.md declares v1, deliberately. They MUST
agree in this tree. This fixture isolates the measured assertion, so it has to
be unable to fail on version drift — the drifted-version case is its own fixture,
`admission-version-drift`. Do not "restore" the mismatch here.
