"""Tests for the state_511_atis_cameras adapter (v0.9.6).

Fixture is a real /List/GetData/Cameras capture (2 cameras: one single-image
UDOT border camera, one multi-image RWIS camera):
  tests/fixtures/state_511_atis_cameras_sample.json

No conftest entry: dedup uses the supervisor-injected cursors.db (inherited
mixin); polling is stateless.
