What it sent and what came back (the newest 2 from our runs)
Read from each run's own recording (rule 73), secrets and signed link tokens taken out. Kept in ~/.logCli/rea/clientFacts.json, so it stays after the run is pruned.

}What it does
Marks Marketplace items as seen by the viewer: it sends input and reads marketplace_set_product_item_seen_state.product_item. It fired during scrolls of the Marketplace browse feed (steps 24 and 36, scroll 1 x 400, and a 978 px scroll), 1.5-3.2 s after the scroll began, as listings came into view.
What our machine does with it
The feed warm-up's scrollMarketplace step (one scroll of 400-800 px) brings listings into view and makes the client send it. The machine does not wait for or read it; the scroll step passes on its own movement.
What can go wrong
None seen: all three answered 200 in 652-1029 ms. Nothing waits on it, so a failure would not stop the run.
