The demo seed's summary was hardcoded when the book was split into modules,
and it drifted the moment the book grew: it reported 12 demand deals and 5
capacity commitments against a database holding 13 and 6. Caught by reading
the seed's own output beside the table it had just written.
Nobody would have noticed for a while, because the numbers were close enough
to look right — which is the whole problem. That output is the only feedback
`pnpm db:demo` gives an operator, and a command that misreports what it did
teaches you to stop reading it.
Counted in SQL now, including the number of distinct stages, so the line
about the pipeline covering every stage is a measurement rather than a
promise the seed makes about itself.
