The substrate raises a third context's store

Each context owns its own database (novox/hq ADR 0008), so a third context is a
third database, created and named the same way — which is the whole of adding
one to the bootstrap, and is why the count is not something the substrate has
an opinion about.

The schema step verifies all three now. It checked two while creating three,
which would have reported success for a context whose tables were never made.
