Model

The developer's by-kind index: where each CORA aggregate's CHX content lives. It hosts no content of its own. Design-phase scaffold.

For the aggregate shapes see the architecture model and the per-BC modules.

Aggregate (BC)	Where at CHX
Asset (Equipment)	Inventory (in this zone)
Computed / virtual axes (Equipment)	Inventory (EnergyAxis)
Capability, Method (Recipe)	Techniques
Enclosure (Enclosure)	The beamline (11-ID-A optics, 11-ID-B endstation)
Zone, Conduit, Policy (Trust); Actor (Access)	Governance
Procedure, Recipe, Caution, Supply, Subject, Run, Campaign, Dataset, Decision	deferred (design-phase; see below)

Deliberately not here yet

This is a design-phase scaffold (descriptor + docs), mirroring HXN, BMM, SRX, and the Diamond beamlines. Left out on purpose:

• No new Family. CHX is a reuse-and-reinforce deployment: the area detectors bind Camera, the flux counter FluxMonitor, the thermal stage TemperatureController, the fluorescence detector EnergyDispersiveSpectrometer, the beamstop BeamStop, the mirrors Mirror, both monochromators Monochromator, the coherence-defining and guard slits Slit, and the compound-refractive-lens focusing optic the graduated Transfocator catalog Family (a CRL focusing optic, also bound at 4-ID, 8-ID, 9-ID, i22). The Transfocator graduation settled the focusing-optic abstraction, so it is a normal catalog reuse like Mirror; what remains open for the transfocator is only its per-Asset lens material and count, tracked as CRL-1. CHX also carries a second, distinct kind of refractive focusing optic, the endstation kinoform lenses (k1/k2): a single profiled refractive lens, not a compound-lens transfocator, so it does not bind the Transfocator Family. It is named but not modelled as a device; whether a kinoform earns its own Family is a separate future question if a deployment binds one, not part of CRL-1.
• The held loose family. The BeamPositionMonitor (4-ID, 8-ID, 9-ID) binds a loose family that other deployments also use and that stays loose, matching the catalog note that position monitors stay loose; it is recorded in the promotion-review register.
• No new Capability or Method. XPCS and small-angle scattering sit on the deferred xpcs / small_angle_scattering Methods 8-ID left pending (TECH-1); CHX reinforces both without coining either, and records no Practice until they land. The correlation analysis is ComputePort work, not a Method.
• Operations and experiment views, integration scenarios, vendor Models. A runbook and registered Assets for a beamline CORA does not yet drive would be invention; they land when the design firms and the team confirms. The 2-BM Model page shows the shape a fully-modelled deployment carries.
