Assemblies, snapshotted at pickup.
BHA Builder holds the saved assemblies and snapshots the one that goes in the hole: bit, motor, and the full component line, with the sensor-to-bit and motor measurements that every later calculation depends on. The Object Explorer carries a BHA level in its tree, tying each BHA to its own surveys instead of one flat wellbore-level list.
