"""Tests for the state_511_atis adapter (Castle Rock ATIS, Idaho).

Fixtures are real captures (one record + its matching marker per layer):
  state_511_atis_<layer>.json         -- POST /List/GetData/<Layer> .data[0:1]
  state_511_atis_markers_<layer>.json -- GET  /map/mapIcons/<Layer> matching item2

No tests/conftest isolation entry is added: dedup uses the supervisor-injected
cursors.db (inherited mixin) and discovery is stateless -- no adapter-owned cache.
