AP2 and MPP mandates
This page is not written yet. It is in the sidebar because it is part of the documented information architecture, and leaving it out would hide the gap rather than name it.
The Interop section is planned in full. Until this page is written, the
authoritative source for anything on it is the code: the API surface is in
apps/api/src/routes, and the clause engine is in
packages/chain/src/verifiers.ts.
