Read from the board that exists. Eight sections; four are about work and
workers and are held back with that domain. The other four are the mesh
itself, and everything behind the main one already exists here — it is a
reader, not a second source of truth.
The constraint is the point of writing this down now. The existing board
is one service that reads every context's database, because that is the
shortest path to a page showing all of them at once. That is ADR 0008
violated by the one component with a reason to violate it, and the cost
is the same one the shared library has: a boundary nothing may cross is a
boundary that can move, and one thing crossing it is enough to freeze it.
So a board reads through interfaces and stores nothing. If a question is
slow, the answer belongs in the context that owns it, where everything
else asking gets it too.
