I fell into a trap the other day and posted about it on fedi instead of just updating the status page and sending a link. I hacked a little on timelines to load, and I'm doing more network stuff today. Some stuff on FSE (mostly /objects/) gives "Revolver-ID" headers, this kind of thing works (though that endpoint is likely to disappear some time):
Might spend tomorrow on a detour into reworking it so that large media uploads work properly. (They propagate through the network fine, but some stuff needs reworking for them to function efficiently when sending large files to clients.)
