How exactly does your average planetary governor know how to tell psykers from non-psykers in a planet's population? And how do the Black Ships know if a world is doing its due diligence to get them?

Would they use a percentage estimate? e.g. each time we visit we expect at least [x]% of your population to be psykers. Or are there witch-seeking tools (that actually work)?

I initially thought that they would wait for an obvious manifestation and then swoop in, but considering what a single untrained psyker can do, that seems dangerous.
Also, what's to stop a planet government to just outright kill anyone suspected of psykery? Would they get punished?
