Feed: your newest post is in Following from the first ask, and a new post goes to the feeds it belongs to. Adam posted from the laptop with the #photography feed open and found the post in #photography (untagged) but not in Following, on either device, until a later refresh. Two causes. The feed's opening ask (prefetchFeed, and seedOtherFeeds) took only the first 400 of its authors, and your own key was added after the follows — with 898 follows it sat in the third chunk, so the opening ask never named you; the later refresh (feedPass, every chunk) did. Your key now leads the author list, and the opening ask covers every author, a chunk per ask. And publishPost put the provisional post at the top of whatever feed was open: now it goes to the feeds it would reach — the open feed and Following when they carry your posts (Following, a people feed with you in it, Everything) or a topic the post wears — swapped for the signed event or withdrawn in each. The hashtags in the text go out as t tags (NIP-24, up to the hashtag-spam count), so topic feeds here and elsewhere find the post. tools/own-post-feeds-test.js (450 follows: every one asked, your key first; a post from Following; an untagged post from a topic feed stays out of it; a tagged one lands in both).

+// Your own posts and the feeds. A Following feed's opening ask takes the
+// authors in chunks of 400, and your own key used to be added last — with
+// hundreds of follows it sat in a later chunk, and the feed opened without
+// your newest post. Now your key leads, and every chunk is asked. And a new
+// post goes to the top of the feeds it would reach (Following; a topic feed
+// whose tag it wears, which is now a t tag on the event) — not to a topic
+// feed that happens to be open and doesn't match.
