Luke Parker a404944b90 Add a SubstrateBlockAck message to the processor ... When a Substrate block occurs, the coordinator is expected to emit SubstrateBlock. This causes the processor to begin a variety of plans. The processor now emits SubstrateBlockAck, explicitly listing all plan IDs, before starting signing. This lets the coordinator provide a SubstrateBlock transaction, and with it, recognize all plan IDs as valid. Prior, we would've had to have a spotty algorithm based upon the upcoming Preprocess messages, or if we immediately provided the SubstrateBlock transaction, then wait for the processor to inform us of the contained plans. This creates an explicitly proper async flow not reliant on waiting for data availability. Alternatively, we could've replaced Preprocess with (Block, Vec<Preprocess>). This would've been more efficient, yet also clunky due to the multiple usages of the Preprocess message.		2023-04-20 15:26:22 -04:00
