 The shipped vertical path is `@deepseek-ai/dsh-goal/remote → Browser Client API → Connection RPC /api → Host Gateway → GoalService.remoteExportCreate()`. The same direct descriptor with an Agent lookup supports both `ctx.api.goals.create(agentId, request)` and `agentCtx.goals.create(request)`. `@RemoteContext('agent')` remains the distinct scoped-receiver mode.
