Fetch a signed feed.json from the public bambuddy-notifications repo on GitHub at startup and every 6 hours. Nothing about the install is sent; targeting (version, beta channel, install type) is decided locally. - Ed25519 against a key built into the app; an older serial is refused so a withdrawn message can't come back. The feed replaces the stored list, and a failed or rejected fetch keeps the last good one. - Sidebar entry above System with an unread count, a slide-over list, and a banner for unread important/critical messages. Read state per user. - Admins by default; Settings > General > Updates can show them to all users or switch them off, which also stops the fetch. - Plain text only; links to github.com and bambuddy.cool only.

"""Announcements from the Bambuddy maintainers, and who has read them.
|
|
|
|
Fetched from a signed feed on GitHub (services/announcements.py). Only the ones
|
|
that target this install are stored, and the feed is authoritative: a message
|
|
withdrawn upstream is deleted here on the next fetch, together with its read
|
|
markers.
|
|
|
|
``AnnouncementRead.user_id`` is nullable: with authentication off there are no
|
|
users, and the install's read state is a single NULL-keyed row per message.
