Just to note what might be obvious but I wonder throws a query with the talk of perpetual web.
It’s possible to overwrite an alias with new content… nothing wrong with that and I guess that the date stamping is there but can date stamps be trusted or are those local to the user?..
So, example that was to hand, creating safe://eye2.eye2 sees alias created for safe://eye2
then writing safe://eye2 with something different breaks that bounce to safe://eye2.eye2
which could create an illusion of content having been one thing after it was something else?
If I changed by system clock, perhaps the illusion below would be more confusing?
