Unit tests cover the SQL gate, broadcast codec, Hive writer layout,
and flight kinematics. CI runs pytest first; the simulator image build
runs tests in a dedicated stage before the final layer.
One process per drone: seeded patrol kinematics, sensor streams at
realistic rates, detection events, hot current/ blocks sealed into
Hive-partitioned Parquet, and the compact UDP state broadcast with
peer RSSI derivation. Scales via docker compose --scale.
