Term-by-term attribution finds otherwise: these benefits belong to granularity choices, to the index and the decompressor, hold only inside a restricted framing, or cannot be found in measurement at all — while the costs are format-level and permanent. The conclusion is polite but total: as a format design decision, fixed-output is not worth adopting.
