Domain boundary
commerce.purchase tells the parser which intent labels and dimensions are valid for commerce. It is not a preclassified user intent.
Schemas
A schema selects the domain. It does not supply the intent.
The caller chooses a bounded vocabulary such as commerce.purchase; IntentParse still discovers the user’s intent from the raw message.
Schema catalogs
A planned next phase will group curated, versioned schema families into catalogs for industries and areas of practice. Every schema remains individually evaluated before a production claim.
Completion
Required dimensions and clarification rules determine when the discovered intent has enough information.
