Techniques

What the modelled part of P23 is designed to do, as intent. First cut.

A technique is a portable Catalog Method; a Practice is how a facility adapts it. P23's diffraction technique earns no catalog Method today, so the Method below renders unlinked and is carried pending until a technique enters scope (TECH-1).

In-situ X-ray diffraction

P23 measures diffraction (and imaging) of samples under in-situ / operando conditions, electrochemistry, thin-film growth, and controlled sample environments, on the experiment diffractometer.

Technique	Catalog method	Notes
In-situ / operando X-ray diffraction	diffraction	diffraction of samples under in-situ conditions; reuses the diffraction slug P07 / P08 / P21 share, a further consumer (TECH-1)

A thin in-situ diffraction beamline

P23 is a thin in-situ diffraction beamline. Its technique reuses the diffraction slug already carried across the fleet, so it forces no new Method. The instrument anatomy reuses existing Families (LinearStage); the sparse registry slice means the model is deliberately thin, with the optics / diffractometer grouped and the detectors carried pending. The in-situ sample environments (the operando cells), if present, would be sample-environment Assets bound when the registry exposes them.

Not modelled yet

The concrete acquisition recipes (the diffraction scans, the in-situ / operando time series, the environment-coupled measurements) are not written yet; they join as the deployment approaches the point where CORA drives P23. Whether the diffraction Method enters CORA's catalog is an owner-scope decision on Model; see Open questions for the world-facts to confirm first.
