The A0 Markdown +remains authoritative if this answer omits or changes a requirement. + +The reference oracle tests the application behavior independently. It does +not prove that these source files parse or lower to the same machine. + +`host.toml` is admitted against the closed Uhura deployment schema. Browser +history is injected by the standard `web.history` capability. The application +module does not implement or wrap it. The order observation and return request +ports use the generic `app.provider` boundary implemented by `provider.mjs`. +That module returns exactly those two adapters. The browser admits them against +the exact adapter, checked contract, and instance identities in +`uhura-play-config/1` +before any command crosses the boundary. Adapter deliveries enter the +`uhura-browser/2` machine boundary through the browser runtime's deferred FIFO +bridge, so foreign code cannot synchronously reenter a machine reaction. + +The provider owns its live seed order and accepted return settlement +independently from `conformance.uhura`. Removing evidence source removes +previews and conformance artifacts without changing the live Play dependency +graph. `ReturnDesk` has `Unit` configuration, so this answer intentionally +omits the manifest's optional `configuration` field. A non-Unit machine must +instead provide one TOML string containing canonical tagged Uhura value JSON; +the host type-decodes and genesis-preflights that exact value before Play is +available. diff
