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.

On Android the microphone now opens the app handling
RECOGNIZE_SPEECH (FUTO Voice Input, Google's), the default the person
chose in Android, and puts the text it returns where the cursor stood,
as Dictation does; cancelled, nothing. Only where none is installed, or
it can't be opened, does speech_to_text listen in line as before.
halkyon_app: VoiceInputApp (one listen, an answer once closed) on the
channel app.halkyon/voice_input, which DeviceSpeechInput asks first at
every listen, answering SpeechStart.finished so that Dictation doesn't
listen again; speech_to_text isn't touched on that route, so our app
asks for no microphone. SpeechInput.listen and Dictation.start take the
prompt the voice input app shows (the field's hint).
Each app: VoiceInput.kt (queryIntentActivities, startActivityForResult,
the first of EXTRA_RESULTS) attached in MainActivity, which hands it
activity results, and RECOGNIZE_SPEECH among the manifest's queries.
The privacy pages of Learn and Meditate say so.
Our own Whisper and Meditate's dream recordings are dropped (D18).
Whats-New: The microphone now dictates through your phone's voice input app, such as FUTO Voice Input.

The developer asked for Todo, Train and Meditate to offer Learn's
Appearance and Language (ADR 0014's amendment of 4 Nov 2026). Their
model, store, cubit and card move into halkyon_app: Appearance and Look
(a BCP 47 tag, null for the device's language), FileLookStore keeping it
in the app's support folder as JSON written by rename (per device, not
synced, read before the first frame), LookCubit for the apps to provide
above InstanceGate, and LookSettingsCard / DeviceLookCard with the texts
moved from Learn's arbs (look*, the same words). Each app passes the
languages it speaks, named in their own language.
Learn keeps its stored choice where it was, among its DeviceSettings,
and feeds the shared card from them: no migration, so nobody's language
or appearance moves, and nothing changes on its screen.

The developer's review of 4 Nov 2026. Below the question, × and + stand
at the start, who answers is centred and the conversations and the
microphone stand at the end, every button the same rounded square, the
microphone listening and Send too. The row above the text ("Only what I
choose · 2 parts") goes, as +'s sheet offers the same choice; a web
search gets + with that row alone. Who answers shows its model's name
alone ('Haiku 4.5', AssistantProvider.modelName: Anthropic's without
"Claude", others as they are), outlined in its provider's colour (D60).
The microphone is halkyon_app's Dictation: what is said goes where the
cursor stands, and it listens again after each pause until stopped. It
gives way to Send once anything could be sent, as Claude's field does.
Whats-New: The question's buttons are in one row: close and + on the left, who answers in the middle, Conversations and the microphone on the right.
Whats-New: What goes along is chosen under +, for the web search too.

On GrapheneOS, which installs no recogniser, the microphone did nothing
and stayed listening: speech_to_text's initialize throws a
PlatformException (recognizerNotAvailable) there rather than answering
false, and DeviceSpeechInput let it through. A listen now answers how it
went (SpeechStart: listening, noRecognizer, unavailable) and never
throws; Learn's field and Meditate's dream say that no speech
recognition is installed and name two to install (FUTO Voice Input,
Google's speech services), in halkyon_app's texts. It also passes
androidNoBluetooth, as the apps declare no Bluetooth permission the
plugin would otherwise ask for.

Learn's `SpeechInput` and `DeviceSpeechInput` (ADR 0021, D67) are
halkyon_app's now, and its `FakeSpeechInput` is in `testing.dart`, so
Meditate's dream journal (ADR 0038, D15) listens through the same code.
Learn imports them from there and behaves as before: its composer and
its tests are unchanged but for the imports, and `DeviceSpeechInput()`
asks for what it asked before.
`DeviceSpeechInput` takes three options, off by default:
- `preferOnDevice`: on Android, recognition on the device where it can
(Android 12 on), else offline; should that fail before a word is
heard (not a pause), it listens as Android otherwise does from then
on.
- `pauseFor`: how long a pause may last before the recogniser stops.
- `listenFor`: how long one listen may last at most.
`Dictation` writes what is heard where the cursor stands
(`DictationInsertion`: in place of a selection, set apart by a space),
shows the words so far, and listens again after each pause while it is
on, stopping by itself after three listens running heard nothing.
speech_to_text moves from Learn's pubspec to halkyon_app's, the lock
unchanged. Todo, Train and Meditate link the plugin now; their
generated plugin registrants (macOS, Windows) say so. An app declares
the microphone itself, and Todo and Train declare none, so nothing
there can listen.

The public profile was already one per person for every service of an
instance (the register, ADR 0016); its app side was Learn's alone. It
moves into halkyon_app: the model, the repository on the module's
endpoints, the form, the avatar drawn on the device and the sheet with
someone's profile. They take the Public prefix (PublicProfileRepository,
BasePublicProfileGateway), as Train's own ProfileRepository holds the
body's figures. AppDependencies gains profiles and files, the picker the
avatar is chosen with, which moves out of Learn too.
HalkyonProfile is every app's Profile screen: the person's own tab first,
the same in every app (the account and the ways they sign in, the app's
own cards, then the public profile), then the app's own tabs, folding into
the title. Learn adds its inbox and Statistics. Train adds Progress, Days
and, where nothing records, Plans, and so opens on the person's tab, no
longer on Progress. Todo, which has no Profile tab, opens it from a row at
the top of Browse, where Todoist keeps the account.

- Explore filters by what a studyset's licence lets a learner do: adapt
it (no NoDerivatives) and use it commercially (no NonCommercial),
which the instance reads from the release's licence
(ExploreQuery.adaptable, commercial) and the app the same way
(LicenseUse). An instance from before ignores both.
- While the studysets are read, the Library shows shimmering skeletons

- An agreement to what goes where is per provider (protocol and host):
agreeing to one assistant agrees to every assistant of that provider,
those granted later too, and the agreement sheet says so. No
migration: it is written on every grant of the provider, so taking
one back keeps it for the others, and read per provider from any of
them.

Halkyon Learn's ADR 0021, D57 to D63, on halkyon_base's budgets and
effort:
- The operator's screen is an overview (Waiting, Operators, Accounts,
Assistants, each with its count) whose rows open screens of their own,
read 50 at a time as they scroll (OperatorListCubit, OperatorPage), so
hundreds of accounts push nothing else down (D62).
- A handle is picked among the accounts there are (AccountSuggestionField):
appointing an operator and granting take no other (D61).
- AssistantGrantsScreen replaces AssistantGrantsCard: the assistants set
up by provider, with their efforts and prices; the people granted, found
by their handle's start; one sheet granting several assistants, a
provider's at once, to several people, each with one budget in money and
tokens a day and a month, or changing one person's (D58, D59).
- Assistants are grouped by provider wherever they are listed, each under
its name with a dot in its colour (ProviderLabel, D60).
- AssistantsCard shows what is left of the person's budget for all their
assistants together; the months of the figures run oldest first (D57).
- AssistantChoice says the efforts a question may ask at and the ceiling
on output each asks for (D63); a person's own key gets none and keeps
4,096 tokens.

ADR 0021, D9 and D17. Before a question sends a private studyset's
content to a remote model, through the parts chosen or a wider reach
with private studysets switched on, a warning names the studysets, the
provider's host and its terms (where checked: Anthropic, OpenAI,
Google, OpenRouter), and is asked once per studyset and assistant: the
agreement is kept in the person's sealed settings (schema 13,
privateAgreements, folded only where both rows hold it), shown in the
studyset's privacy dialog with Take back, and marked on the folded
button while it holds. Follow-ups and Try again ask again once taken
back, as the scope keeps where the parts came from (partsFrom). No
warning for an own assistant on this machine (loopback or localhost,
halkyon_llm's LlmEndpoint.onThisMachine); the local network may be
shared.
Texts that step 3 made untrue: the consent sheet now says what an
assistant looks up goes too and that conversations are kept encrypted
for the person's devices; the privacy dialogs no longer mention
showing a studyset to Claude; the privacy page says what is looked up
and when a private studyset goes.

ADR 0021, step 2's app half. halkyon_app asks the module's assistant
endpoints (ServerpodAssistantGateway, ServerpodAssistantOperatorGateway)
and a person's own provider directly (halkyon_llm), behind
AssistantRepository: an AssistantChoice is a GrantedAssistant, asked
through the instance, which counts it, or a PersonalAssistant with the
person's own key, which the instance never sees. assistant_messages.dart
turns a conversation into the endpoint's models and back.
AssistantsCard, for an app's settings: what is granted and left of its
limits, agreed to once on a sheet saying what goes where, the person's
use by UTC month, the instance's privacy page, and their own assistants
where the operator allows own keys (kept ones stay listed, unasked,
where it doesn't). AssistantGrantsCard on InstanceOperatorScreen: grants
by handle with their limits in the pricing's unit, changed and taken
back after asking, everyone's use by month; a found account's menu
grants too. Nothing shows where nothing is offered or can be read.
package:halkyon_app/assistant_models.dart holds the models in pure Dart.
Learn keeps own assistants in the person's settings (ownAssistants,
schema 12, SettingsOwnAssistants); SettingsRepository.update refuses
(OwnAssistantRefused) to write a key where the settings would not be
sealed (SettingsGateway.seals). Learn depends on halkyon_llm directly.
Todo wires the gateways; a member offers no assistant. No feature asks
an assistant yet (step 3).

Whoever operates the instance approves, refuses and suspends accounts
and names other operators in the app (D21 to D24, D34):
- halkyon_app: InstanceOperatorRepository on
ServerpodInstanceOperatorGateway (the module's instanceOperator
endpoint; refusals as OperatorFailed: notFound, isOperator,
lastOperator, notAllowed for 401 and 403, failed), in AppDependencies.
OperatingCubit counts the accounts that wait: asked as the person's
app opens, after every change, and every 5 minutes only while they
operate the instance, so nobody else's app keeps asking.
InstanceOperatorCard (or its tiles) and WaitingAccountsBadge show
nothing at all for anyone else. InstanceOperatorScreen, laid out as
Settings: the accounts that wait, each showing its four words to read
out before Approve (D33), Refuse for new ones after asking; who
operates, Take back after asking, the last always kept; Name an
operator by handle; Find an account by the start of its handle, with
Suspend after asking and Name as operator. English and German texts
("Admin" as the role word in German).
- Learn: the card right after the Sync card in Settings, which the
cogs' count leads to as their dot leads to Sync; the count on the
Settings cogs of Home and Profile.
- Todo: the tiles in the account sheet and the count on its button.
Todo's server is a member, whose `operating()` is always null, so
nothing shows there until it holds the register.
Tests: the gateway's mapping, the repository, both cubits with their
denials, the card, the badge and the screen; Learn's Settings shows the
card and the count to an operator and neither to anyone else.

An account signed in or up to on an instance whose operator approves
new accounts, or one suspended, gets no session but a wait: the device
keeps its pass, words and handle in the keyring per instance
(SecureAccountWaitStore, InstanceStorage.waitOf), the auth status is
Waiting, and SessionGate shows WaitScreen in its own app, so the start
screen's sheets go with it. Every sign-in flow hands over to it: the
password's sign-in, sign-up, reset and account reset, SimpleLogin's
sign-in, sign-up and mending; their cubits show no problem then.
The wait screen shows the handle, the four words the operator reads out
for the person to match, and that Halkyon never asks anyone to read them
out (D33); it asks where the wait stands as it opens, every 30 seconds,
as the app comes back and when asked. A new account can be deleted with
its pass, a suspended one can't (ADR 0017). Approved, it leads to the
usual sign-in, once more as before (D31); a pass the instance knows no
more ends the wait. The start screen says where new accounts wait for

Every account signs in with SimpleLogin or a password now, so GitHub
goes from the module, the shared app package, Learn and Todo, ahead of

- halkyon_base: no `gitHubSignIn` endpoint, GitHub identity provider or
GitHub refusals; no `githubClientId`/`githubClientSecret`, no

mailed to the person's own address; an account without one sets none
(`wrongCredentials`).
- Learn's server: `instance.info()` without `gitHubClientId`, the
pruning without GitHub, and `minimumAppBuild` 24, as builds up to 23
(v0.20.0) require `SignInWays.gitHub`: the server deploys with the
release of build 24.
- halkyon_app: no GitHub button or problems on the start screen, no
password offered after a GitHub sign-in, and `ServerpodAuthGateway`

ways back.
- Learn's Profile lists no GitHub; the texts go (English, German).
- Serverpod's `serverpod_auth_idp_github_account` stays, as its
migrations make it; a row goes with its account, and ADR 0020's D36
gives operators the SQL to delete those left.

SimpleLogin's sheet, its password and its recovery phrase both lost:
under the lost-password step's phrase field, Lost your recovery phrase
too? says what stays and what is lost and asks for new keys
(`keys.startReset`) with the sign-in of a moment ago, which the device
then drops. The next sign-in says when while it waits, and once due
offers new keys, the sign-up's own password and phrase steps
(`keys.completeReset`), or the password, which calls it off (D31).
Every app's home shows `KeysResetBanner` where "too old" shows, and the
account section's SimpleLogin row the same words (`KeysResetNotice`),
each with Call it off, the password's proof alone
(`keys.callOffResets`, D32), and, once due on a device that holds the
keys, Finish here, which wraps the same keys anew (D33, D35). Both show
only a reset of an account that signs in with SimpleLogin alone; ADR
0017's resets show in its own section, which now shares `AlertBox` with
them.
An account whose password signs in has no Forgot your password? there,
and is asked its password and a code once while its keys lack the proof
key, at a sign-in or on adding SimpleLogin (`password.setProofKey`,
D34). `PasswordUnlock` carries the proof key, which its forgetting
leaves, and the keys' password proves for a purpose given.

An account that signs in with SimpleLogin opens its keys with its
password. Where that is lost, the unlock step's "Forgot your password?"
opens one step: the recovery phrase, and a new password twice. There is
no address and no code: the SimpleLogin sign-in of a moment ago stands
for them (D20).
- The device opens the keys with the phrase (`keys.beginPhrase`) and
wraps them under the new password (`AccountCrypto.newKeysPassword`).
It then signs the phrase's proof bound to that password
(`signKeysResetProof`), which `keys.resetPassword` takes with the
sign-in. The keys stay, and every other session ends.
- A phrase that doesn't open the keys is refused on the device, and the
instance gets no proof to count. Two passwords that differ are
refused before anything is sent.
- The gateway's `beginPhrase` and `resetPassword` run on the account's
own session, not yet the device's. The repository's `resetPassword`
ties them together, and the cubit and sheet have their `forgot` step.
Three texts are new, in English and German.
- halkyon_base_server exports `isKeysPassword` for the interop test,
which checks against the register's checks, with real libsodium, what
the device sends.

Every new account gets a handle, and an account without one gets its
first as it sets a password. The handle is private until its person
goes public (D5).
- `passwordSignIn.signUp` takes a handle. `passwordSignIn.checkHandle`
says whether a sign-up could take one, only while that sign-up's
mailed code waits (`codeExpired` otherwise), counted per code request
(30 an hour) and per network (60) (D29). Members ask the register.
- `password.set` takes the first handle of an account without one
(D28); `SignInWays.handle` tells the app whether there is one.
- Each checks the handle before the code is used, so a refusal leaves
the code for another try. An existing account at the address keeps
its own handle where it has one, and the typed handle is still
checked, so the answer says nothing about the address.
- `first_handle.dart` holds what SimpleLogin, the keys and passwords
share: `refusalOfNewHandle`, `insertFirstProfile`, `hasHandle`.
- halkyon_app: one `HandleField` with its `HandleCheckCubit` (asked
300 ms after typing pauses, only about the handle typed last; the
instance's suggestion is free without asking) (D30). The password
setup asks for the handle between the phrase check and the code, and
a refusal at the code sends back to it. SimpleLogin's sign-up and
keys steps use the same field and now check as it is typed.
- The module's README and ADR 0020 (D29, D30, the built state) amended.

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.

halkyon_app reads where the device's person stands with SimpleLogin
(nothing to show, linked, or missing) and shows it in SimpleLoginSection,
which each app places above the password part: Add SimpleLogin, once
added one more way in. GitHub is added to nobody where SimpleLogin is
offered, and Learn's Profile offers an anonymous person SimpleLogin
alone there (D23).
No cut-off day, reminder or banner (D24): with the developer the only
person on learn.halkyon.eu, the cut-off is the operator taking GitHub's
OAuth app out of the deploy's settings once that account has SimpleLogin.
ADR 0020 records it and drops step 5.

Where the instance offers SimpleLogin, the start screen offers it first,
saying that the instance keeps only the SimpleLogin ID, and opens a sheet
that waits for SimpleLogin's page in the browser (Cancel ends the wait),
then: for someone new, the choice between creating an account (the
suggested handle or another, checked with the instance, the password
twice, the recovery phrase shown once and three of its words typed back,
nothing reaching the instance before) and linking theirs again with its
handle and recovery phrase; for an account, its password opening its
keys; for an account of before, the keys made with the handle it lacks.
SimpleLoginCubit holds the steps, each refusal shown where it is mended
(a handle's on the handle, a sign-in to begin again on the browser's),
and closing the sheet stops waiting on the loopback.
The suggested handle is never checked: the instance suggests none that
anybody has, and every answer about a handle counts against its limit
(D5). The fake's handle rule is now the module's.
Learn and Todo build it with SimpleLogin's browser (halkyon_oidc_flutter,
now a direct dependency of both, with their names on the loopback's
page), their schemes and their loopback ports (43823, 43824), as the
instance's forwarding page has them. Their tests offer no SimpleLogin;
halkyon_app's test the sheet.

SimpleLoginRepository signs in with SimpleLogin in the browser
(OidcBrowser: the app's scheme on Android, iOS and macOS, the app's port
on the loopback on Linux and Windows, D9), then makes the account's keys
and signs someone new up, opens an account's keys with the password, gives
an account of before its first keys, or links a new SimpleLogin account in
place of a lost one with the recovery phrase (D7), which opens the keys on
the device first: a phrase that doesn't fit sends no proof, and no
password is asked after. An anonymous person adding SimpleLogin keeps the
keys their device holds. Nothing is the device's until `enter`.
SimpleLoginGateway calls halkyon_base's `simpleLogin` and `keys`
endpoints (ServerpodSimpleLoginGateway), with a fake for tests, as does
FakeOidcBrowser. The calls made on clients of their own (signed out, or as
a session not yet the device's) move from the password gateway into
BaseCalls, which both share.
Fixes BaseProtocol, the client of halkyon_base alone, which didn't read
halkyon_oidc's classes: every refusal of SimpleLogin's sign-in on a
signed-out call would have reached the app as a failure. OidcBrowser keeps
its loopback private, so that a fake can implement it.

AccountCrypto makes the keys of an account that signs in with SimpleLogin
(newKeys): new key pairs or an anonymous person's device keys, wrapped
under the password and a new recovery phrase, with the public half of the
password's proof key in place of SRP's verifier. It proves the password to
open them (proveKeysPassword: one Argon2id for the proof and the unwrapping)
and the recovery phrase to link a new SimpleLogin account in place of a
lost one (signMendProof, bound to the attempt). The interop tests check all
three against the register's own checks.

OidcBrowser opens the page of an attempt the server began (OidcStart),
waits until the browser comes back by an OidcReturn (the app's scheme,
a verified https address, or the loopback) and returns the provider's
code (OidcCode), its refusal (OidcDenied), or nothing when the person
closed the browser. It checks the returned state against the attempt's,
as the server never compares it; a wrong state, neither one code nor
one refusal, no browser or a failed way back are OidcCallbackExceptions.
halkyon_app's LoopbackWebAuth moves in with its tests, relicensed from
AGPL v3 to BSD-3-Clause by its author, the developer; GitHub's sign-in
keeps using it from there until it ends. The package is BSD-3-Clause,
publish_to: none, as the module (ADR 0023, D2, D3).

The reading of 22 Oct, against an instance that alters data. A data key's
ID now says what it is for (a studyset's key naming it, the person's key,
or a record that a studyset was made readable), and the ID is sealed with
the key and signed by the account, so the instance can't relabel a key or
make one up; the row's own columns are no longer trusted. A studyset is
private while the latest signed record about it says so, and the device
keeps the latest it saw in a ledger in the person's folder (privacy.json),
so a record withheld or a row replayed changes nothing; a tree's key is
the nearest studyset's with such a record, itself or above. An item keeps
the key it was last seen sealed with unless this device moves it or a
signed record makes its tree readable.
A readable row a device holding the keys writes carries the account's
signature in place of a nonce; one nobody signed is locked wherever
privacy holds (in private trees, for items once sealed, and for tags and
settings once sealed), so the instance can't plant content, confirm a
guessed tag name by folding, or switch Count me on. Signed readable rows
from a device that hadn't heard are shown and sealed anew.
Rewrites are kept as under way until done, write the top studyset last,
hold writes into their tree meanwhile, and are finished as the data opens
and after each merge; a sweep seals what a stale device wrote. Cards moved
into a private tree are sealed with their files first; cards of a private
tree are never moved into a readable one. A private topic moved out of
its tree keeps its privacy with a key of its own. Settings carry a counter
inside their sealed payload, and a lower one than seen is refused. The
person's readable tags and settings are sealed once. A device without the
keys of an account that has them writes nothing that would be private and
reports nothing for the learner count; an anonymous person's keys kept but
unreadable are never replaced. Publishing sends only the names of the
tags the release carries. Key refusals are remembered per row.
Tests on the real gateways over a local database: a replayed readable top
row, a withheld key record, a moved parent, a planted revision, a signed
stale revision, card and topic moves, an interrupted rewrite, a settings
rollback, a device without keys, planted tags.

- `ContentKeys` opens the person's data keys (`content_key`) with their
account's keys on the device, an anonymous person's device keys made as
their data first opens; it makes a private studyset's key and the
personal key. Without the account's keys nothing opens and nothing new
is private (D8).
- `PayloadEnvelope` is the one place payloads are sealed and opened, each
for its table, row and column, so a payload moved to another row never
opens; one that doesn't open is `Locked`, never half-read.
- `Privacy` gives each gateway the key of the row's tree (its top-level
studyset's), and rewrites a tree under another key, or readable, in
place (`rekeyTree`).
- The studyset, card, note, learning path, path answer and PDF gateways
seal with their tree's key and open what they read: a new top-level
studyset is private where the device holds the keys, a new one inside a
tree takes its privacy, and one moved into another tree is rewritten
under that tree's key. Tags and settings are sealed with the personal
key; a tag or settings row that doesn't open here is left out, so
nothing folds or deletes it. A studyset whose key doesn't open shows as
locked (`Studyset.isLocked`); other rows that don't open read as blank.
- Every payload codec round-trips sealed, and refuses another row.

`ContentCipher` makes a person's data keys, sealed to their account and
signed by it, opens them, and seals and opens a row's content with them for
the row it is stored in (`SodiumContentCipher`, on the isolate it is used
on, as rows are read and written one by one; `FakeContentCipher` for
tests). A sealed payload holds the signature, then the ciphertext.
`AccountCrypto.newDeviceKeys` makes the key pairs an anonymous person's
device encrypts their private studysets with (ADR 0017, point 9, not built
before); setting a password keeps them as the account's
(`keepingKeys` with a new phrase), so nothing they made private is lost.

Both went through the launch screen (SessionStateLoading), which closed the
person's app before asking the instance; a failure then opened it again
with no word of why. The person's state stays now, saying what is under
way (`busy`), and a failure keeps them signed in with why (`problem`). An
instance out of reach still signs out on the device (Serverpod's
signOutDevice), as signing out of a borrowed device must work offline, so
only the device's own storage fails a sign-out; a deletion fails whenever
the instance isn't reached or refuses.

Where an instance offers password sign-in, GitHub is added to nobody (ADR
0017, D2), yet the start screen still said "then add GitHub" after a GitHub
account nobody has, and every refusal but an unknown account read
"Couldn't sign in with GitHub." (the end-to-end test of 21 Oct).
- The gateway tells from one read of the basics whether GitHub signs in and
whether it is added to people (`gitHubOffer`, in place of
`gitHubClientId`); the GitHub bloc keeps it (`Ready.linking`) for the
profile, with why an attempt failed (`Ready.problem`).
- The instance's `usePassword`, `deprecated` and `ended` become problems of
their own (`gitHubSignInProblemOf`), worded by `gitHubProblemText` and on
the start screen; an anonymous person refused a link is told the GitHub
account is nobody's and offered the password instead.
- Where passwords are offered, the start screen offers an account to create
in place of the app's hint on adding GitHub.

- 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.

On Apple's systems a keychain read finds only the entries of its own
accessibility, so forgetting everyone's keys but one person's missed those
builds before had kept with the default or first_unlock_this_device: they
stayed after signing out, a switch of person or removing the instance (the
short reading's L5). forgetAllBut now also reads the keyring with every
accessibility a build used and deletes each entry found by name, which a
delete finds whatever its accessibility; one that can't be read now holds
back none of the others. The repository's forgetting, run as the person
changes and not awaited, catches a keyring that can't be read (a locked
device), where its error went unhandled.

SecretScreen built its child alone, and a stack around it with the cover
while the app was away (iOS), so each switch of apps built the child anew:
a phrase field lost its focus, its caret and what the keyboard was
composing (the short reading's L4). It always builds the stack now, laid
out as the child alone (StackFit.passthrough), the cover in it only while

The fields the recovery phrase is typed back into offered the system's

all alone, and the field's own copy and cut, overridden from above, do
nothing. The comment on the recovery codes no longer speaks of Copy.

The short reading's H1: open(2) takes its mode among variable arguments,
which Apple's Arm passes on the stack, so bound with three fixed ones it
read the mode from whatever the stack held: a phrase or recovery codes
saved on an Apple silicon Mac could be readable by everyone. It is bound
as variadic now (VarArgs), and every file written is made 0600 through its
descriptor (fchmod), checked.
M1: macOS's sandbox lets an app reach the file the person chose and
nothing beside it, so the file made beside it was refused and nothing
could be saved; Learn's sandbox allowed reading chosen files alone, so its
exports never saved on macOS either. There, writePrivately now writes the
chosen file itself (decided by the developer on 21 Oct): opened without
following a link or waiting on a pipe and without truncating, refused with
nothing written unless fstat finds a file of the own user's, then made
0600 and emptied. Both apps' entitlements grant reading and writing the
files the person chooses. Linux keeps the new file renamed over it.
The reading's nits: the buffer is wiped whatever happens, an interrupted
call is made again (EINTR), the file made beside a chosen one is named
apart from it so a name as long as a folder takes still saves, the folder
is flushed after the rename, and Linux reads a file's type and owner with
statx, alike on every architecture, where __lxstat's version differed
(riscv64's was wrong). The test of another user's file is skipped as root.
The in-place path is tested on Linux; none of it has run on a Mac.

A person still anonymous on a member was deleted there on the session
alone while the register was out of reach (the reading of the fixes' B1).
But the register may have linked them while their becoming identified on
the member failed, so with both failing, an account of the register's went
without its proof (the short reading's L2). A member now refuses every
deletion while it can't ask the register (decided by the developer on
21 Oct).
In the app, signing out of an anonymous account, which deletes it, signs
the device out all the same when the deletion fails, as a switch already
leaves one behind: the account is left to the instance's pruning of
anonymous accounts unused for 90 days. signInWays gets its doc comment

PasswordUnlock.forget zeroes them: the sign-in cubit wipes what the

as it closes; a change's or deletion's proof wipes what it unlocked once
its answer is made. The fake crypto's proof copies its bytes, as a real

The reading of the full reading's fixes found that SignInWaysState kept
Equatable's default text, which debug builds log with the address, and
that an unreadable sign_in.json logged its FormatException, whose message
holds the file's text; and that the account section's Delete caught only
refusals, so a keyring that couldn't be read escaped and the tap did
nothing.
The state says only whether an address is kept; the file's error logs its
type alone. Reading what keeps the account counts the keys as not here
where the keyring can't be read, and Delete goes on whatever the reading

then removed the first deleted the second's folder, session and keys while
it was in use, losing unsynced changes, and an anonymous account for good.
The places keep the names installs made (InstanceStorage.sharesWith says
which addresses share one): choosing an address the device keeps where a
known one is puts it in that one's place in the list, and removing an
address forgets nothing another known one uses. The build's own instance
keeps its place apart. Learn and Todo pass the storage's rule.

The reading of the full reading's fixes found that first_unlock_this_device
left the account's private keys readable on a locked phone once it had
been unlocked after starting, which is what forensic tools extract from a
stolen one; and that, the accessibility being part of every keychain
lookup, an entry kept with another class stayed unseen and made the next
write fail as a duplicate, so that person couldn't finish signing in on
that device.
As the developer decided, the keys are kept unlocked_this_device (still
never in a backup nor in iCloud Keychain); nothing decrypts with them
while the device is locked. Keeping keys deletes the entry first, which a
delete finds whatever its class.
