Open questions

What CORA needs the ISS team to confirm. This model is reverse-engineered from public open source (the NSLS2/iss-profile-collection bluesky / ophyd startup files): the EPICS PVs are read from the startup/*.py device classes, but undulator parameters, crystal cuts, vendor identities, and physical positions are not. Each row is a fact the beamline team owns. It is a delete-on-answer queue.

Priorities: Blocks-build, Blocks-go-live, Nice-to-have.

Source and safety

ID Priority Question CORA assumes Resolves
SRC-1 Nice-to-have The 8-ID insertion-device identity, period, and gap range. The profile collection drives photon energy through the HHM trajectory and does not expose the undulator gap PVs; only the ring current (SR:OPS-BI{DCCT:1}) is read. An in-vacuum undulator on the 3 GeV ring, identity-only. The InsertionDevice settings.
PSS-1 Blocks-go-live The PSS search-and-secure permit-leaf PVs. Only the shutters (XF:08ID-PPS{Sh:FE}, XF:08IDA-PPS{PSh}) are in source. The permit signal is a confirm note, not a guessed PV. The Enclosure permit signals.

Optics

ID Priority Question CORA assumes Resolves
DCM-1 Nice-to-have The HHM and HRM crystal cuts, reflections, and energy ranges. Both monochromators (Mono:HHM, Mono:HRM) and the HHM trajectory controller (MC:06) are in source. One trajectory DCM and one high-resolution mono Asset, crystal settings blank. The Monochromator settings.
ENERGY-1 Nice-to-have ISS's measurement sweeps the energy axis (EXAFS) as a trajectory fly-scan, the textbook case for the energy-scan Capability the catalog anticipates. Does CORA coin energy_scan now, or keep it deferred until a conduct-path forces it? Energy-scan deferred (the BMM question); ISS is a further consumer that strengthens the case. The energy-scan Capability decision.

Sample and detectors

ID Priority Question CORA assumes Resolves
SPEC-1 Blocks-go-live The Johann and von Hamos crystal emission spectrometer geometry: the analyzer crystal cut, the Rowland-circle radius, and whether each of the (Johann: main + four auxiliary) analyzer crystals is a child Asset or a setting on the one spectrometer Asset. Two EmissionSpectrometer Assets (catalog Family, graduated at this 2nd sighting after LCLS-MFX); crystals as settings for now. The emission-spectrometer model and analyzer-crystal composition.
DET-1 Blocks-go-live The detector roster: the ion-chamber channel map (I0 / It / Ir / If through the ICAmplifier / Keithley-428 amps and the analog pizza box), the Xspress3 element count and ROI map, and which Pilatus serves which spectrometer. The ion chambers, the 4-channel Xspress3, and one Pilatus modelled; channel maps blank. The detector roster and channel maps.
TEMP-1 Nice-to-have Which sample-environment thermal units are live (the Lakeshore 331 is in source; cryostat / furnace not). One TemperatureController Asset; the others noted. The sample-environment Assets.
ENV-1 Nice-to-have The ion-chamber fill-gas flow (He / N2 mass-flow controllers XF:08IDB-OP{IC}FLW:) and the broader in-situ sample environment. None fits a catalog family cleanly (the loose FlowController). Deferred; fill gas and in-situ environment named here, not modelled. The fill-gas and in-situ Assets.
DIAG-1 Nice-to-have The beam-position channel map (the Prosilica BPM cameras and the sample-positioner cameras) and the BeamPositionMonitor sensor fold-vs-promote hold. Read-only beam-position (loose BeamPositionMonitor) probes; channel map blank. The BeamPositionMonitor bindings.

Controls and technique scope

ID Priority Question CORA assumes Resolves
DRIVE-1 Blocks-go-live The motion-controller box models, firmware, and IPs (the Delta-Tau HHM trajectory controller MC:06, the von Hamos MC:3-Ax: axes, and the EPICS motor records). Families bound (MotionController), specifics blank. The MotionController Models.
TECH-1 Blocks-go-live Do the X-ray absorption (EXAFS) and X-ray emission (XES / HERFD) techniques enter CORA's catalog as Methods, or stay pending? ISS reuses the xas_spectroscopy Method LCLS-MFX left pending, the second consumer. The xas_spectroscopy Method reused pending; no new Method coined (the BMM / SST deferral discipline). The technique Method scope.
