+In FrostFS every operation can fail on multiple levels, so a single `error` doesn't suffice,
 e.g. consider a case when object was put on 4 out of 5 replicas. Thus, all request execution
 details are contained in `Status` returned from every RPC call. dApp can inspect them
 if needed and perform any desired action. In the case above we may want to report
 these details to the user as well as retry an operation, possibly with different parameters.
 Status wire-format is extendable and each node can report any set of details it wants.
 The set of reserved status codes can be found in
-[NeoFS API](https://github.com/nspcc-dev/neofs-api/blob/master/status/types.proto). There is also
