      execroot/                           <== The working directory for all actions. For special
                                              cases such as sandboxing and remote execution, the
                                              actions run in a directory that mimics execroot.
                                              Implementation details, such as where the directories
                                              are created, are intentionally hidden from the action.
                                              Every action can access its inputs and outputs relative
                                              to the execroot directory.

                                              stdout/stderr for every action from the most recent
                                              bazel run that produced output.
