No, not this kind of stranded sats, rather, a LN newb question. (I got inspired to ask my dumb questions in public after listening to @siggy47 podcast with @kr last night.)
Is there any notion of an inactivity timeout, or liveness limit, for sats in a SN wallet? For instance, if someone got 10k sats in their SN wallet, and never withdrew them to anywhere, and never showed up again, would the sats just sit there forever? Or is there a timeout of some kind that puts them back in a pool?
Is it correct to say that whatever the answer is, this is basically a SN policy decision, not a LN protocol issue? Because in this case, SN is acting as a custodial wallet, right?
