Ordinary users do not need development dependencies or the test suite. Explicit Profile selection is independent of automatic discovery markers: selected plugin guidance still runs when a marker is absent, and reports `not_evaluated` when no source evidence is available.

Professional guidance is activated independently by explicit Profile selection, even when automatic discovery markers are absent; without source evidence the result is `not_evaluated`.
