If you called twice and they say it is on, that seems a clear message. Getting a direct confirmation of AF cannot be something you ignore. Also to be found on the CDG website as planned departure. No clue why they have an additional flight number. Maybe something to do with a change from Winter to Summer time and a change in departure time. Obviously if the old flight number is dropped many tracking tools will show it as cancelled, and they may not pick up the new somewhat strange flight number. I further assume you will be able to check in online since you were rebooked - another obvious sign the flight is a go. Even if OLCI fails I'd better show up at the airport in time since you have so many signals the flight is a go (rebooked, called twice, info on the CDG site below).
