Source trails should be inspectable.
Not heavy.
Not academic.
Not performative.
Just visible enough.
Where did this thought come from?
Is it from an older public post?
Is it from a current conversation?
Is it a synthesis?
Is it provisional?
What else does it connect to?
That matters because notes can sound more finished than they are.
The source trail keeps the note honest.
It lets a person follow the thread.
It lets an agent avoid overclaiming.
It makes the public graph easier to trust.
The idea can stay simple.
The trail can carry the context.
