The control plane the beamline runs on, and the seam CORA's edge conducts over. Control plane: EPICS / bluesky.

ESM runs on the NSLS-II EPICS / ophyd control stack, the same floor as the other NSLS-II beamlines. The device handles above are bound from the beamline's bluesky profile collection (NSLS2/esm-arpes-profile-collection), carried confirm pending staff verification (CTRL-1). The ARPES acquisition (the energy moves, the analyzer sweeps, the manipulator scans) runs through bluesky plans and the queue server (40-ESM_plans.py, 41-ESM_motion.py); that orchestration is the seam CORA's edge replaces, driving through ophyd / EPICS. The analyzer's spectrum file-writing is plumbing CORA observes, not data it owns (see model.md).
