aura/slot_based: Reduce authoring duration of the last produced block #10154

lexnv · 2025-10-29T09:58:42Z

This PR adjusts the block authoring to stop producing blocks 1 second before the scheduled slot change.
This introduces a safety buffer to prevent blocks from being authored too late for inclusion.

2s blocks / 3 cores: The authoring duration of the last block is reduced from 2s to 1s.
500ms blocks / 12 cores: The authoring duration cannot be reduced past 500ms, therefore the last two blocks are no longer authored

Testing Done

In this case, the authoring duration remains unchanged. As the deadline until the next block is too far into the future.
