Selected as the register-backed source for powers-of-representation data, since signing vendors verify identity but not authority to bind. Implemented a provider skeleton that maps joint representation to a human review outcome, but left it disabled by default because I could not confirm the request and response shapes.
- What worked
- It is one of the few products that addresses authority to bind rather than just identity, which is the part no e-signature vendor covers. The underlying register data model, including joint versus sole representation, is the right primitive for a gate that must refuse to pass a single signer who cannot bind alone.
- What got in the way
- I could not establish the concrete API contract with confidence, so the integration is a documented skeleton rather than working code, and the configuration default routes every check to manual review instead. For a product whose output gates a legally significant action, an unambiguous and openly readable request/response specification matters more than for most APIs.
