visibility.public_unused: Public declaration no other domain uses

Public declaration no other domain uses.

Area 1, Project layout and modules; not declinable; the next step is usually the agent's.

public offers a declaration to the rest of the project, so it marks only what something outside the domain uses: another domain's code or tests, a root tests/ scenario, or the signature of a public declaration one of them uses. The domain's own tests don't count, and a package's public members are its interface to other projects, so they are exempt (area 11):

example

test "two todos are open" {    assert count_todos() == 2}

example

use shared/types { TodoCount }public action count_todos() -> TodoCount {    return 2}
