/// root frame: the Return buffer on success, the Abort buffer on a
/// deterministic revert, or the Fault variant when no root output was
/// produced (e.g., non-deterministic failure).  Downstream indexers and
/// the receipt-read paths surface this as `return_data`/`abort_data`.

/// `gas_consumed` is the gas the whole transaction consumed: the root frame,
/// every frame it invoked, and the pre-execution validation of attached
/// contracts. On an out-of-gas fault it is the transaction's gas limit. It
/// is part of the leaf, so the events root commits to it and every
/// validator's re-execution must reproduce it.
