That commit throttles two writes and states a statement order. Only one of the three claims was defended. touchLastSeen is the hotter of the two writes — it ran once per indexed record, so a busy firehose meant a database round trip per event for a timestamp read in hours or days. Deleting its throttle outright left every existing test green, as did keying it globally instead of per DID, which would let one busy account suppress every other account's first write. Both now fail. The statement order is the third claim: UpdateLastUsed stamps the throttle before the write rather than after, so a slow or failing write cannot let every concurrent caller through to queue another attempt behind it. That matters because this runs on the authentication path, once per layer during a push, and the pile-up is worst exactly when the database is least able to absorb it. A failing write makes the ordering observable without timing anything: with the stamp after the write every call retries, with it before only the first does. Dropping the table leaves no row to inspect, so the attempts are counted through the warning the function already logs. Under the reordering it reports 10 attempts across 10 calls.
