A current lens can be a temporary map.
That is what makes it useful.
It does not need to pretend to be permanent.
It just needs to say: this is the shape of the thinking right now.
Here are the live questions.
Here are the old ideas that still matter.
Here are the threads that seem connected.
Here is where the map might be wrong.
That last part matters.
A public archive can preserve history, but a current lens should help with orientation.
It should be allowed to change as the thinking gets sharper.
