History — the State component's transitions log
How this works
Checkout copied the customer's shipping and billing addresses into this order's own
Address slots, and each product's title and price onto the order's lines. These are
copies, not links, so editing the product or the profile later leaves this order alone.
Mark shipped transitions the State in slot fulfilment,
which appends to its transitions log. Checkout's request key is stored here too, but this
page never shows it, so it is never read.

Every slot row also has id, entity_id (this
entity's id) and timestamps. Ids are cut to their first block. The rows are the ones this page loaded,
so the panel adds no queries.
