Function status_from_frame 

fn status_from_frame(frame: &CallFrame) -> InstructionResult

Maps a callTracer frame to the InstructionResult used for the rendered [status] label.

callTracer only exposes a coarse, human-readable error string (plus an optional revert_reason), not a machine status code, so we recognise the two halts geth and reth report reliably (an explicit revert and running out of gas) and fall back to InstructionResult::Revert for anything else. push_frame preserves the frame’s error / revert_reason text in the trace output, and the call is coloured by CallTrace::success, so an imperfect status never hides a failure or the original error message.
