A public note should know its job.
Not every note has to do the same thing.
Some notes name a concept.
Some preserve a question.
Some point to a source trail.
Some invite a conversation.
Some clarify a boundary.
Some connect old writing to current thinking.
Some make a claim that needs proof nearby.
The job matters because it changes how the note should feel.
A question note should not pretend to be an answer.
A source-trail note should not become a manifesto.
A concept note should not try to carry the whole system.
If the note knows its job, the reader knows how to enter it.
And an agent knows how to route it.
