@btravstack/pothos

Pothos fields that call oRPC procedures, for a GraphQL gateway in front of contract-first services. The default export is the plugin, listed after @unthrown/pothos's: plugins: [RelayPlugin, ErrorsPlugin, UnthrownPlugin, OrpcPlugin].

• t.procedureField(procedure, { type, call, input, output, refusals? }) validates the field's input through the procedure's own contract before calling it, decodes the answer with output, and answers each error the procedure declares as the GraphQL error class registered for its code — a member of the field's result union. Field-local refusals override the builder's shared orpc: { refusals } defaults. Together the maps must cover every error call can return and InvalidInput; a missing code does not compile. A declared error handled by a narrower call needs no entry.
• t.procedureConnection(procedure, { …, connection }) is the same for a Relay connection, with the decoded page folded by connection.
• UNAUTHORIZED and FORBIDDEN are answered as GraphQL's own error, with extensions.code, whether the procedure declares them or not.
• loadProcedure and procedureErrors are the same answer through a DataLoader; contractCall, contractInput and contractOutput are the contract half on its own.

Every dependency is a peer: Pothos plugins and graphql each need one copy. Install @btravstack/contract alongside them; contractInput reuses its /orpc input-schema accessor.
