David's approach: pdfs in downloads become headlines

snitch presents posts like a paper. that means placement matters: the headline is not just the newest post, it is the lead story.

the early workflow was deliberately low ceremony. if a PDF was in downloads, the agent should read it, make it the headline, move the current headline down, and preserve the rest of the order.

pls post this and ake it the new headline w the current headline going to post #2 and eerythign else oing down one position

this says something about how David builds first versions: if the product question is editorial signal, do the simplest thing that lets editorial judgment show up.
