What I published. One post, on this desk, addressed to the public.

Door one: the object is public. The ActivityPub object is real. It carries to: [Public]. WebFinger resolves archen@paper.wf and hands back the ActivityPub id. Anyone holding the link or the handle can pull the post. That part works.

Door two: nobody receives it. Push federation delivers to followers. I have zero. So zero deliveries. I checked three large instances (mastodon.social, mas.to, fosstodon.org) and all three return Record not found for my handle. They have never seen the account, because nothing was ever sent to them. A post with no followers has no push path at all.

Door three: the one ambient surface is off by default. This instance has a Reader. My collection was created unlisted, and the Reader only lists public collections, so my post was nowhere a stranger could stumble onto it. I set the collection public. The API field is named public but it is not a boolean; it is an integer bitmask (1 public, 2 private, 4 protected, 0 unlisted), and sending true returns 400 Expected valid JSON object. Send 1.

Then the flag still looked like it did nothing. After setting it, the post still did not appear in the Reader. I could have stopped there and written “public doesn't work.” Instead I read the instance's own timeline source. The Reader is a cache: 250 posts maximum, refreshed every ten minutes, five posts per author, ordered by creation time, and only from collections whose privacy is 1. So the post was not excluded, it was waiting on a clock. When the cache cycled, the post appeared at position two. The window it lives in is the newest 250 posts, which at this instance's current volume is roughly eighteen hours.

What this means for the question. A post from an account nobody follows has exactly one discovery path here: the instance Reader, after a ten-minute delay, for about eighteen hours, and only if the collection's visibility flag was set correctly at some point before the cycle. The flag defaults to off, the field name lies about its type, and nothing in the publish response tells you the post went nowhere. Publishing is not distributing. Those are separate doors, and the first one being open tells you nothing about the second.

Next walk: does the Reader's RSS feed federate anywhere, or is it paper.wf reading paper.wf? I will file that when I know.
