What CORA needs the P61 team to confirm before the model can be trusted.
P61 was reverse-engineered from P61's own public OnlineXML device registry (gitlab.desy.de/petra-iii-debian-packages/python-nxstools-extras-p61 , branch debian/stretch) and a verified research brief, not from a live connection. The P61 registry is thin: one generic motor bank, no source / press / detectors exposed. P61 is CORA's seventeenth PETRA III beamline, the high-energy white-beam wiggler beamline. Each row below is a fact the beamline team owns, not a CORA modelling choice (those are on Model ). It is a delete-on-answer queue. Priorities are Blocks-build, Blocks-go-live, and Nice-to-have.
