Contribute

The draft is open. Help make it precise before it hardens.

Four ways in

Comment on the draft. Cite the section, describe the ambiguity, and provide an example that exposes it.

Propose a capability. Supply a dotted path, description, required actions, and applicable extension.

Propose an extension. Supply the field schema, extra checks, freshness rules, and an operator willing to implement the proposal.

Build a reference implementation. Publish a record and implement the actions. The first target is a real, independently evidenced booking completed end-to-end, starting in one dense market.
