Leios adds incremental-decoding benchmark results

What happened.

Ouroboros Leios merged PR #1019, described in the supplied record as adding incremental-decoding benchmark results. The work is part of efforts to quantify how nodes decode blocks and headers under the Leios design.

This is a development update rather than a release or an operational outcome. The available record frames it as evidence that decoding cost is being measured, not only modeled.

Why it matters.

Decoding-cost benchmarking is a practical question for a higher-throughput design: nodes must be able to decode the data they receive. The update therefore adds an empirical measurement step to the Leios development track.

It also sits alongside reported proto-devnet, tracing, threat-model, and architecture-diagram work. Taken together, those items suggest work is moving toward more observable and benchmarked development, though the supplied evidence does not establish results from that broader effort.

What to watch next.

The useful next receipt is the benchmark readout itself: published figures or methodology for incremental decoding, and any stated throughput or latency results. Those details would allow operators and builders to assess what the added benchmarks found.
