4.8.0 cannot be reached in one step: it refuses to start until the database has run the release
before it (prisma -> drizzle; measured on both venues; the box undid it by itself in 20 s). So the
first step is 4.7.0. Bench 9401 (harness v4, swap 0): the first user made through /api/setup and
logging in before and after, 10-min watch 0 kills (anon peak 41.7 %); the abort starts and serves.
Box 9202: done in 103.6 s through the setup gate, the user logs in. PostgreSQL 16 does not move.
