The Directory comes from the directory service (#205)

Browse Source 
ipx asks ipx-directory on its people's behalf, with the token an admin set
in the new Admin, Directory tab, so the page never talks to it and never
sees the token or a feed's address. /api/directory, /api/popular and a
feed's Directory page answer from it; subscribing takes the address from
the directory and goes through Add feed's steps. With no directory set
up, the Directory says so. The local directory code is gone; its privacy
checks are the snapshot builder's now, and their tests moved with them.

With sharing on, ipx sends its snapshot after every scan, whenever the
config changes (set_cfg) and every half hour: each public feed and how
many here subscribe, never an OPML or Patreon creator itself or anything
private. A feed can be marked private in its settings, for a paid feed
whose address does not give it away; anyone subscribed may mark it, only
an admin unmark it. The admin's category for a feed that names none goes
with it, which the directory uses only while the feed names none, so the
category an admin gives a blog still reaches the Directory.

The directory lists only feeds it has read as a feed: the first snapshot
after a start went before the first scan, when an OPML was not yet known
to be one, and the directory listed the OPML. It now fetches what a
snapshot brings in at once instead of within the minute.

The browser suite runs its own ipx-directory on SQLite; the Directory's
tests match feeds by title, since the directory names them by address.
