What's the difference between traces and trx.trx? It's not consistent.

Answer 1

A trx contains a list of actions that were submitted to the blockchain along with the execution status. A trace shows each inline action called by the actions from the trx. There are other differences too, but I don't know what they are and I leave that for someone else to answer/edit this answer.
