An address of one word (`todo`) was read as https://todo/ and looked for,
the person waiting up to 15 s for no instance to answer. A host is now a
domain of two labels or more, an IP address or localhost; anything else is
"This isn't an address." as it is typed. localhost and loopback addresses
typed without a scheme are reached over HTTP, as a server running on the
same machine has no certificate; HTTPS where typed (the developer's
review, 9 Nov 2026).
Whats-New: An address of a single word is now refused at once, rather than looked for.
Whats-New-De: Eine Adresse aus nur einem Wort wird jetzt sofort abgelehnt, statt danach zu suchen.

Every account has a way in, so the apps make no anonymous account any
more. The start screen shows whenever nobody is signed in, a first
start included, and offers SimpleLogin, a password and GitHub for those
who have it, with no start without an account. An instance out of reach
is said so, with Try again, and one offering no way to create an account
too. An anonymous account's session left from before is deleted as the
app starts (D25), falling back to signing out on the device.
What only anonymous accounts needed goes: signing in anonymously, the
signed-out mark, adding GitHub to an account and switching to a GitHub
account from the Profile tab (with its Cancel, the only one), an
anonymous device's own keys, the warning that signing out deletes the
account, and the texts about keeping progress. Settings says on which
instance the account is signed in. Learn's publishing, reports and
suggestions and its learner count no longer ask whether the person has
an identity: everyone signed in has one.
The server still offers anonymous sign-in until the next commit, so
older apps keep working until v0.20.0 raises the minimum build.

- Deleting an identified account whose security can't be read (the
instance out of reach) says so and deletes nothing; it went on to a
deletion by the session alone, refused for an account with a password,
and the person saw a spinner, then nothing. A refusal still leaves the
session's own deletion.
- InstanceChoice's sharesStorage is required, so no app leaves it out and
removes a folder another instance uses.
- A PasswordUnlock forgotten is spent: its secrets read again fail
(StateError) rather than make a proof or a wrapping of zeros.

What the app sends an instance (the proofs that sign in, the keys'
wrappings, every request a session carries) must not be read or changed on
the way, so an instance is reached over HTTPS, or over plain HTTP only on
this machine (localhost, 127.0.0.0/8, ::1), as Jellyfin servers are. An
address over plain HTTP elsewhere is refused before anything is sent there.
One kept from before is never opened: the app says why, and offers another
instance or removing it from the device, never dropping it silently.
Development builds still use their own instance over HTTP (an emulator
reaches the developer's machine as 10.0.2.2); releases never.

An operator's DATA_LOCATION and BACKUP_LOCATION may name a subdivision
(ISO 3166-2, US-CA, DE-BY) besides the EU or a country. The app adds
"(EU)" to a member country and the country to a subdivision ("Germany
(EU)", "California, United States", "Bavaria, Germany (EU)"), in
English and German, and shows the most specific flag there is: a
subdivision's own where the flag package has one, else its country's.
Subdivision names come from Unicode CLDR 48.2 (tool/subdivision_names.py),
bundled with their licence, which the app registers.

What every Halkyon app's shell needs, taken from Halkyon Learn's and set
on halkyon_base's client: the instances a device keeps an account on,
the first start's tiles and where an instance keeps people's data, the
account switcher; signing in anonymously, with GitHub or an email code,
switching person and the start screen; the gates that build an app's
dependencies per instance and per person; and the sync service with its
status, Settings card and banner. Texts of its own in English and
German take the app's name; what only the app can say, it passes in.
Fakes for apps' tests are in testing.dart.
An instance's basics now name the app it serves (`app`, set by the
host's configuration), and an app accepts only an instance of its own.
SerialQueue and CoalescingRunner move into halkyon_core.
