These are Result Codes that communicate success (200) or failure (400) at the operation level: no source account, too many subentries, etc.
Each entry shows the Horizon result code, then the Stellar protocol code.
op_inner opINNER
The inner object result is valid and the operation was a success.
op_bad_auth opBAD_AUTH
There are too few valid signatures, or the transaction was submitted to the wrong network.
op_no_source_account opNO_ACCOUNT
The source account was not found.
op_not_supported opNOT_SUPPORTED
The operation is not supported at this time.
op_too_many_subentries opTOO_MANY_SUBENTRIES
Max number of subentries (1000) already reached
op_exceeded_work_limit opEXCEEDED_WORK_LIMIT
Operation did too much work
