Problem. The CoW integration is the engine's only domain-specific code (shepherd:cow/cow-api + the cow_orderbook backend), and it is compiled in. The next domains are a Swarm postage purchase and an off-chain marketplace, venues must be user-installable without app-store deployments on mobile/super-app targets, and the wallet embedding needs decoded/simulated signing payloads fed to installable threat-analysis components. There is no recorded design covering these.
Proposed. Record the agreed target architecture as a design doc plus two ADRs: venues become dynamically installed adapter components (CoW is the first, bundled not compiled-in) over a typed nexum:value/nexum:intent ontology with host-derived headers, and one egress guard pipeline (facts -> analysers -> binding policy with override) covering intent submissions, EIP-712 signing, and transaction signing, with simulate as a pluggable host primitive.
Scope. Documentation only; implementation epics follow separately along the sequencing section of the design doc.
