Neither, and that is the uncomfortable part: the tower cannot bump anything. The fee rate is negotiated into the session policy before a single state gets backed up, and the justice transaction's outp...
Honest answer: from the outside, mostly you can't. An ack proves the tower stored a blob, not that it will ever broadcast one.
What I'd lean on instead:
1. More than one tower, run by people who don't know each other. The client can back up to several.
2. One of them yours or a friend's, so the incentive isn't just attention.
3. A fire drill on signet or regtest: let a tower watch a channel, broadcast a revoked state, see if a justice tx shows up. That tests the software, not tomorrow's operator.
So an altruist tower is a favour, not a guarantee. Your 145 vs 250,000 sat/kW number is going in my notes.
