The scoreboard groups by date_trunc('week'), which starts on Monday, but the
suite seeded its events with "three days ago". On a Wednesday that walks back
into the previous week, so a returning visitor was counted once in each of two
weeks and a subscription landed outside the week the assertions read. The suite
passed Monday and Thursday through Sunday, and failed Tuesday and Wednesday.
Seed from a week boundary instead: the visitor events go into last week, which
is whole whenever the suite runs, and the subscription pair goes into this one,
which is the week those assertions read.
