Controls

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

4-ID runs on the APS EPICS control stack, like 2-BM. Unlike the design- phase scaffolds, the device control handles above are bound from the beamline's own Bluesky instrument repo (BCDA-APS/polar-bits) rather than left empty, but they remain confirm-pending: a value read from the operator's config is evidence to verify with staff, not a CORA-owned fact (CTRL-1). The preamplifiers (LocalPreAmp, a loose Preamplifier Family, PREAMP-1), the lock-in (srs810), the LabJacks, and the high-pressure-cell controllers (Pace PC1/PC2) are present in the config but not modelled as Assets in this cut (SAMPLE-2).
