When it runs
Always on: this lens is convened on every review, whatever the change touches. Always-on specialists are the cross-cutting ones — the concerns that do not belong to a file type, and that nobody thinks to ask for.
Its 3 lenses

That second half is what makes the verifier pass possible at all: it is not asking whether a finding is correct, it is asking whether this specialist covered its own declared ground.
