Pin represents a ledger-pinning event that has been detected from the blockchain, in the sequence that it was detected.

A batch contains many messages, and each of those messages can be on a different topic (or topics) All messages on the same topic must be processed in the order that the batch pinning events arrive from the blockchain.

As we need to correlate the on-chain events, with off-chain data that might arrive at a different time (or never), we "park" all pinned sequences first, then only complete them (and generate the associated events) once all the data has been assembled for all messages on that sequence, within that batch.

We might park the pin first (from the blockchain), or park the batch first (if it arrived first off-chain). There's a third part as well that can block a message, which is large blob data moving separately to the batch. If we get the private message, then the batch, before receiving the blob data - we have to upgrade a batch-park, to a pin-park. This is because the sequence must be in the order the pins arrive.
