Well, shit: you're right.

I do realize that Signal is open source, yes (and I'm guessing from your phrasing you know I know that), but I don't feel a moral imperative to source dive every time someone says something weird. Putting that burden on the claimant seems pretty reasonable. This set of threads alone was exhausting enough without having links to GitHub with every message :-)

In particular: I interpreted your "stored (at least temporarily)" claim as in like, a logfile that's rotated daily or something. I think we can both agree that would be much worse than a 60 second leaky bucket and hence I interpreted that as more outlandish than what you intended.

But regardless, you're right: that's not how it works today, I read that code an extremely long time ago (when it was really just sender ID limited), and having both sender and receiver in plaintext is clearly worse than having just one, and having a leaky bucket with a timer is clearly a much higher resolution timestamp than the day previously claimed. I'm guessing the distinction is between what's stored and what's not? But I'm definitely uncomfortable and will make a note to follow up. In particular, now I would like to know under what circumstances that Redis cluster will attempt to persist. I think the answer is "never--it only has caches and the directory", but you've definitely shaken my confidence in that answer :)
