//                       MODIFYING THE API INTERFACE
//
// When adding / changing methods in this file:
// * Do the change here
// * Adjust implementation in `node/impl/`
// * Run `make gen` - this will:
//  * Generate proxy structs
//  * Generate mocks
//  * Generate markdown docs
//  * Generate openrpc blobs
