Castopod announces an episode with a Note that only links to the episode's page, which serves a PodcastEpisode. PrivaPub
reads PodcastEpisode (its words in description, its sound in audio, its cover in image), and a Note that is only a link
to its author's own episode takes the episode's sound, title, cover and words, so the post plays. A server that
publishes no NodeInfo is described from NodeInfo2 (/.well-known/x-nodeinfo2), as Castopod publishes.

Smithereen joins the pasture (tools/pasture/peers/smithereen.sh): its image on the shared MySQL, with imgproxy and a
file server behind Caddy, a JDK trust store with the pasture's CA, accounts from its signup form, and a password grant
for a local application. scenarios/smithereen.sh drives its VKontakte-like API: friends as mutual follows, wall posts,
comments, likes, reposts (quotes there), polls, edits, deletions, private messages, the unfollow and statistics, 30
checks. A post on someone else's wall never reaches PrivaPub, since Smithereen sends it only to servers whose actors
publish a wall: G-0009, waiting for the owner.
PrivaPub: a server description that failed (Smithereen serves no NodeInfo until it has a description) frees its week,
so the server's next arrival asks again instead of a week later.
The shared Postgres takes 400 connections: at 100 the village seed ran it dry (Sharkey's API answered 500, Misskey
dropped deliveries). The seeder records a follow that stands from an earlier seed when the step itself fails, so the
checker no longer expects that follower to see nothing.

Three shapes Funkwhale 2.0 sends, each of which lost something:
- its Accept is named after the Follow it answers, on our origin (`…#follows/<uuid>/accept`), and was refused as off its
actor's origin, so no follow of a channel completed: an Accept or Reject whose id extends the id of the activity it
answers, on our origin, is now taken;
- a channel deletes its uploads in one Delete without an id, their ids in a list as the object's id: each is deleted;
- its NodeInfo discovery names the document under its swagger schema's URL: a link whose path names NodeInfo is taken
when no rel is known.

Mobilizon sends its NodeInfo as `application/json; profile=http://…#` with the URL unquoted, which .NET cannot parse,
so the document was refused for its content type and the server never described; and it names its software
"Mobilizon" where NodeInfo wants lower case. The media type is now read from the raw header when the parsed one is
missing, and software names are lowercased, so one software is counted under one name.

PrivaPub now finds CDNs three ways, best first: the address ranges the
CDNs publish (Cloudflare, Fastly, Amazon CloudFront, Bunny, Gcore,
Imperva), downloaded daily by CdnUpdater and kept in CdnRangeSet; the
CDN's fingerprint in the responses it already gets from a server
(EdgeHintsHandler on the federation client); and the networks that carry
only a CDN. The fixed ASN list is gone; ASNs shared with plain hosting
(AWS, DataPacket) no longer hide a server. A server's Geo records the
CDN, its domain and how it was found, and weekly snapshots now keep the
city and coordinates too.
Servers through time (ServerPlaces): /instances/:host/history lists a
server's weekly snapshots, a CDN-fronted server's geo names the CDN's
domain and where the server was before it (before_cdn), and
/api/privapub/v1/cdns and /cdns/:domain group servers by CDN with week
by week who joined and who left. Owner decisions recorded in ROADMAP.

The public projection of a server's place showed only the country for
servers reporting fewer than 10 users. The owner never decided that
threshold: every located server now shows its city, coordinates (0.1°)
and network, and a CDN-fronted one still shows only its CDN, since the
address reached is the CDN's edge. Statistics:PublicCityMinUsers is
gone; the ROADMAP decision on server locations, CLAUDE.md and the
/stargazing explainer are corrected.

- Touches: the ledger marks a server as touched when it sends us a verified activity, when
we exchange activities with it, or when we read its actors, keys, objects or WebFinger.
It upserts RemoteInstance.Seen, FirstSeenAt and LastSeenAt at most hourly per server, and
queues one DescribeInstance a week with the same dedupe key ObjectRecords uses. Suspended
servers and pages behind link previews are never described. Migration _010 marks the
servers already known as touched, with their dates.
- InstanceDescriber.Describe(host, crawled, allowed) reads:
- NodeInfo 2.2/2.1/2.0, now with its published user counts, posts, comments,
description, languages and schema version;
- for software with a Mastodon API, /api/v2/instance falling back to v1: title,
languages, registration mode, character limit, API version, source URL.
It never keeps a contact as a field; the raw document is kept for the admin only. It
locates the server from the address our connection reached (DB-IP Lite city and ASN, the
CDN named when fronted) and writes a RemoteInstanceSnapshot per ISO week, unreachable
weeks included. A crawled server is upserted as crawled only on insert, so it never
downgrades a touched one, and robots.txt can deny any path.
- PublicGeo.Project is the only public form of a location: a CDN-fronted server shows its
CDN only, a server reporting at least ten users shows its city, coordinates and network,
any other only its country.
