Description
Output only committees do not send LocalPrepare
Always use parent block ID to fetch JMT pending state.
Simplify evidence update apply to transaction pool record
Improve performance of missing transaction processing
Fix leader failure
Reduce/simplify prepare phase evidence
Avoid block propose delay when changing epochs
Motivation and Context
Output-only shard groups do not need to send prepare-phase cross-shard exchanges as they don't involve any inputs. This PR removes this pledging for output only nodes.
The previous pending JMT diffs query used the justify block_id. However, if the justify != parent, the JMT should include pending state for the parent since state changes will still be committed.
