Model catalogue

Use the exact model identifier to select its explanation. Planned and proposed capabilities appear beside related models with their status; they have no selectable type token in this reference snapshot. The parameter index defines individual scientific fields. Features distinguishes editing, execution and planned work in the four interfaces.

Reference snapshot

The machine-readable catalogue records the inspected edi source and its declared crysta SDK, along with the model/parameter identifiers used for this reference. Availability is scoped to that source snapshot; a development build or installed release can differ. Use its declared model list and version when answering a build-specific question.
