Also, I expect "green light" in this context means that it will make it on the EU Parliament's agenda, nothing more. That's still perilously close, but it's not done and dusted yet.
I'm pretty sure the "greenlight" on the title means they are meeting to confirm that the countries will vote in favor of the law so it can be quickly approved once it makes to the parliament:
> If Chat Control is endorsed by Council now, experience shows there is a great risk it will be adopted at the end of the political process.
meaning: there will be little opposition to the proposal once it reaches the MEPs.
