The developer decided on 8 Nov 2026, after trying the variants on the
phone: the wave in the colour of the screen in view, without Material's
ripple, the indicator kept and there at once, a 1.2 s wave, top corners
of 20 dp, the bar's own neutral surface. Learn's bar stays cobalt, the
colour its tabs wash in, rather than its icon's purple.
So the bar has one look: FlushNavigationBar.waveDuration and
cornerRadius are constants, and the debug section goes from the four
Settings screens with what it switched (NavigationBarDebugSection,
debugNavigationBarStyle, effectiveNavigationBarStyle, the style record
and the variants A, C and F, the speeds, the corners and the tinted
surface). Their tests go too; those stating the look kept stay. Learn's
sign-out helper no longer has to scroll past the section.
ADR 0030's amendment of D60, the halkyon_ui README and Learn's
AGENTS.md record the decision and the alternatives set aside.

The developer's review of 8 Nov 2026: the bar follows the screen in view
rather than one colour per app, so a Todo project of its own colour gives
the bar that colour while it shows. The wave, the chosen destination's
icon and label and its indicator take ScreenTint.color, the colour the
screen in view claims through its TopGradient; the frame's accent, the
app's colour, stays only for the moment before any screen claims one,
since ScreenTint itself starts at cobalt, which would be wrong for Todo,
Train and Meditate. Learn's tabs claim cobalt, their wash, so its bar is
cobalt there now, not purple.
A colour changing on the same tab (a project opening) passes into the
next over 300 ms, at once with animations off. A wave paints in that
colour as it goes: it starts in the colour of the screen being left, as
the arriving one claims its own only once it shows, a frame later, and
passes into it with the rest of the bar.
A person's colours may be light, so the chosen destination's colour is
made legible (readableTone, halkyon_ui): a palette colour starts from its
own text tone as Todo's dates take it (its outline in light mode, its
fill in dark), any other colour from itself, then darkens towards black
in light mode and lightens towards white in dark, only until it reads at
4.5:1 on the bar and on its indicator. Every palette colour is tested in
both themes, on the neutral and the tinted surface. This also lifts
Learn's label, which read at about 3:1.
The debug section gains Bar surface, neutral or tinted: tinted mixes 6 %
of the screen's colour into the bar's own surface in light mode and 8 %
in dark, changing with it. Neutral by default, and in the shipping style.
Whats-New: The navigation bar takes the colour of the screen you're on, such as a project's own.
Whats-New-De: Die Navigationsleiste nimmt die Farbe des Bildschirms an, auf dem du bist, etwa die eines Projekts.

The developer's choice of 7 Nov 2026 (the mockup's variant E): a tap on
another destination sends a radial glow in the app's colour over the bar
from that destination's centre, solid to 35 % of its radius and gone at
70 %, growing to cover the bar (cubic(.2, .7, .2, 1)) while it fades from
half its strength in dark mode and a third in light, over 1.2 s, behind
the destinations and clipped to the bar. None for the destination already
chosen, none with animations off, and none for a tab changed without a
tap (a link, back): the wave answers the finger. The destination chosen
takes the app's colour, its indicator tinted 22 % with it, without
Material's ripple or the indicator growing; the bar's top corners are
rounded, 20 dp, the screen showing through them.
Each app gives the frame its colour (NavigationFrame's accent, from
PaletteColor): Learn's purple, its icon's last colour, Todo's strawberry,
Train's carrot and Meditate's fern, their screens' wash.
For trying it on a phone, a debug build's Settings has a section
Navigation bar (debug), halkyon_ui's NavigationBarDebugSection, switching
live, in memory alone: the variant (A Material only, C the wave with
Material's fill, E without it, F without the indicator too), the wave's
time (0.7 to 2 s) and the corners (0 to 28 dp). Release builds never read
it and show shippingNavigationBarStyle, the debug section's start: to
remove it, delete the section from the four Settings screens and
debugNavigationBarStyle, and let effectiveNavigationBarStyle return the
shipping style.
Whats-New: Tapping a tab sends a soft wave in the app's colour across the navigation bar, now with rounded corners.
Whats-New-De: Ein Tipp auf einen Tab schickt eine sanfte Welle in der Farbe der App über die Navigationsleiste, jetzt mit abgerundeten Ecken.

Below medium windows the frame's bar is Material 3 Expressive's again,
flush with the window's foot (decided 7 Nov 2026 by the developer): the
theme's NavigationBar across the whole width, 64 dp in its own colour,
running on beneath the system's bar as Material's does. Right above it a
fade 32 dp high, from the background of the screen in view (the
ScreenTint's, the theme's surface before a screen claims one) made
see-through to that background, so what scrolls on beneath the bar fades
out rather than being cut off; taps pass through it. The rail of wider
windows stays as it was.
halkyon_ui's FloatingNavigationBar becomes FlushNavigationBar, its side
margin, lift and rounded card gone. Its coverOf is now the whole room
content leaves at its end, the system's bar included (the body's bottom
padding: bar, fade and system's bar inside the frame, the system's bar
alone outside it), and floating buttons rise by buttonLiftOf, the same
without the system's bar, which a Scaffold keeps them clear of itself.
Lists, Todo's hour grid and the Plan's sheet keep using coverOf; the
Profile's list no longer adds the system's bar a second time.
Whats-New: The navigation bar sits at the bottom edge again, with a soft fade above it.

Todo stores editor documents too, so the document, the editor, its view,
the format bar, links, the clipboard, scripts and EditorBlocks move, with
their strings and tests, to a shared package on the same appflowy_editor
fork. What is Learn's alone stays in Learn on top of it, and what the
editor took from it directly is inverted: EditorBlocks gains textMarks,
formatActions and onEditorClosed, RichContentEditor a wrapEditor, and an
InsertableBlock's name takes the BuildContext. Learn's screens use
LearnContentEditor and LearnContentView, which add Learn's blocks and the
grammar check. Learn behaves as before.

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

The microphone is halkyon_app's Dictation: what is said goes where the

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.

No file has Compose's default name any more, so .env's COMPOSE_FILE is always set,
naming compose.learn.yaml first (.env.example sets it). compose.yaml stays as a link to
compose.learn.yaml for the one deploy that switches learn.halkyon.eu's .env over: the
deploy's merge runs with the COMPOSE_FILE from before. A later commit removes it.
BREAKING CHANGE: an instance's deploy/.env must set COMPOSE_FILE, starting with

The folder kept its name from before the monorepo (ADR 0015), though
Train and Todo deploy from it too. redeploy.sh, the backup's units and
the operator's steps name ~deploy/halkyon; the Compose project keeps the
name halkyon-learn, as Docker names its volumes after it.
The server moves after this is deployed: the running redeploy.sh is read
whole before it runs, so the deploy of this commit still works in the
old folder; then the folder is moved, the pinned commands in deploy's
authorized_keys and the backup's units changed, and the containers
recreated on the new paths.

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.

conversation's follow-up has the same + and microphone.
Files are read on the device: an image goes as itself to an assistant

each cut at 20,000 characters and labelled by its name after the

Voice is the device's own speech recognition (speech_to_text: Android,

- 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
of their cards rather than a spinner: halkyon_ui's new Shimmer and
SkeletonBox, still where the system asks for no animations.
- The scope's "Include private studysets" is offered only while the

- An agreement to what goes where is per provider (protocol and host):
agreeing to one assistant agrees to every assistant of that provider,

- On a studyset below expanded windows it stands in one row with Add

- While studying, the ratings below the card make way while its field
is open rather than standing under it.
- The conversation opens at the window's full height, its header above
the list, so a drag on the header moves the sheet and a drag on the
list scrolls it. Close ends the conversation; any other way out folds
it into the button (ConversationDockCubit, above the router), its
answer still coming, until any button opens it again or another
conversation starts.
- An answer's Copy icon lines up with the answer's text.
- A sense's grammar notes run on after its glosses as one flowing text,

Switching the sidecar on learn.halkyon.eu's server recreated the server
beside LanguageTool, whose start takes a minute: the server's first look
at the languages failed, and it looked again only an hour later, as
after one that worked. Until then instance.info() named no languages,
and an app that asked meanwhile keeps that answer, so its editors check
nothing until it starts anew. A look LanguageTool doesn't answer is now
tried again a minute later, by a timer, until it answers, the languages
known before kept meanwhile; one that worked still counts for an hour.
The server's tests take fake_async (^1.3.3, as Learn's app, already in

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).

The server half of the assistants (points 4 to 8, D27 to D46): the
operator sets language models in deploy/assistants.env, grants them to
people with limits, and the module forwards their questions with the
operator's key, counting what each used, never what was asked.
- assistantsFrom: ASSISTANTS, ASSISTANT_ID_KEY, ASSISTANT_<ID>_NAME,
_PROTOCOL (anthropic, openai, openai-responses), _BASE_URL, _MODEL,
_KEY, _IMAGES, _PRICE_INPUT and _PRICE_OUTPUT (per million tokens),
ASSISTANT_CURRENCY, ASSISTANT_OWN_KEYS; anything unusable stops the
server as it starts, naming the variable.
- The assistant endpoint (identified): offered, agree (D40), ask as a
Serverpod stream (D35): the text as the model writes it, then the
whole turn, sent once the request is counted; figures, the caller's
own. Checked in order: at most 2 questions on their way per person
(tooManyAtOnce), the grant, the agreement, limits in the pricing's
unit now (limitOutdated), the month's and the day's limits (with when
they reset, UTC), the question (malformed, imagesNotRead, tooLarge
past 400,000 characters, an image over 3,932,160 bytes or more than
20 images); output capped at 16,384 tokens. Each request carries the
person's opaque ID (HMAC-SHA256 under ASSISTANT_ID_KEY, D30). Once
sent, the provider's reply is read to its end even if the app
cancels, and counted on a session of its own; a provider's failure is
logged by kind and status, told as providerKey, providerBusy (with
its wait), providerRefused or providerFailed.
- The assistantOperator endpoint (identified and operator, on the
register): setUp, grants, grant (assistantNotSet, invalidLimit,
notFound), revoke, figures of a UTC month.
- Tables assistant_grant and assistant_figures (per person, assistant
and UTC day), in the module's, Learn's and Todo's migrations. The
daily pruning keeps this month and the two before
(forgetOldAssistantFigures, D41); deletePerson deletes both.
A member offers no assistant (D43).
- instance.basics() gains assistantOwnKeys.
- /privacy (D39, addPrivacyPageRoute, on the register's web server,
before the profile pages' route): made from the instance's settings,
English or German, no JavaScript: who may sign up, where the data and
backups are, what the module keeps (the account, sessions, IP
addresses, the server's log), the host's privacyPagePoints (Learn's:
studysets synced, private ones encrypted on the devices with what
stays readable, what is published, dictionary lookups, the learner
count), each assistant with its model and host, what goes and what is
counted, and whether personal keys are allowed. Never a key.
Tests: 70 on the assistants (grants, limits, refusals in order,
streaming, cancelling, counting, concurrency, the operator's denials,
deletion, pruning), 19 on the settings, 8 on the privacy page.

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.

The developer's decisions of 25 Oct, reviewing ADR 0021 whole:
- What an assistant may see and do (D7–D12): the scope of each question
(the parts ticked, the studyset, its tree, the library), looked up
through read-only tools the app answers on the device; private
studysets out of a wider scope unless switched on, and a warning
whenever one's content would go to a remote model, Lumo included, as
no provider keeps a question confidential while its model answers;
changes only as drafts; progress never; text first, an image when
ticked or asked for.
- What it keeps, does and where it lives (D13–D18): conversations kept
sealed with the person's own key; four features (questions about what
is open, cards from text, explaining a miss, checking a written
answer); grants and limits in halkyon_base, the adapters in a package
of their own (halkyon_llm, BSD-3-Clause); the proposal's points 4–8
and 10 as written; the warning once per studyset and assistant; built
for v0.21.0.
- Sign-ups and operators (D19–D26): SIGN_UP open, approval or closed;
the first operator by SQL, others named in the app; suspending an
approved account; a wait screen with a matching code the operator
checks with the person; 14 days, 10 waiting.
- What people are told and what never goes (D27–D30): the app and a
privacy page of each instance's own; others' posts only with their
author's switch, a copy's licence being its agreement; an opaque ID
per person for the provider.
ADR 0022 and Learn's AGENTS.md now point to it as accepted.

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
ADR 0017's GITHUB_SIGN_IN_ENDS.
- halkyon_base: no `gitHubSignIn` endpoint, GitHub identity provider or
GitHub refusals; no `githubClientId`/`githubClientSecret`, no
`GITHUB_SIGN_IN_ENDS` and no `forgetGitHubAccounts`; the register
loses `account-with-github`. `SignInWays.gitHub`, the basics'
`gitHubClientId` and `gitHubSignInEnds`, and `PasswordRefusal`'s
`signInAgain` and `noAddress` go. A first password takes a code
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`
without the browser half only GitHub used (`(client, base:)`). The
account section offers a first password only to an account with an
address. `LoopbackWebAuth` and the apps' schemes stay, SimpleLogin's
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.
- deploy/: compose.yaml and .env.example without GitHub. The READMEs,
AGENTS.md files and ADR 0017 amended.
BREAKING CHANGE: builds up to 23 can't read the instance's answers
about an account's ways in; minimumAppBuild is 24.

The server's half of D25: every account has a way in, and the anonymous
accounts left from before go with the daily pruning.
- The module signs nobody in anonymously: `anonymousIdp` and
`gitHubUpgrade` are gone, and so is linking GitHub at the register.
- A password is set only by someone whose address is theirs (a
`firstPassword` code) or who signs in with GitHub alone (a fresh
sign-in and a `signUp` code); an anonymous account is refused
`wrongCredentials` before any code is used.
- SimpleLogin refuses to link onto a caller without `identified`
(`wrongCaller`), the member's endpoint too, so nothing turns an
anonymous account into one with a way in.
- `pruneAnonymousPeople` deletes every anonymous account left, however
new, never one identified. Learn and Todo schedule it as
`prune-accounts` and cancel the old `prune-abandoned-anonymous-people`
entry once.
- Learn: someone without `identified` keeps no files;
`FILE_LIMIT_ANONYMOUS_MB` is gone. `minimumAppBuild` is 23, as builds
up to 22 start with an anonymous account.
- Learn's sync tests make their person and session by SQL in the
development database, as Serverpod stores sessions.
- Docs, store listings and ADRs 0010, 0014, 0016, 0017 and 0019 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.

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).

A handle's page and profiles.byHandle answer as for a handle nobody has
until its person goes public: a handle fixed by a publish, or a display
name, a bio, a link or an avatar (isPublic). A person's own profile, and
the host's own lookups (personWithHandle), are unchanged.
So every answer about a new handle now tells that an account has it,
and countHandleCheck counts them together on the register, 30 an hour
per person (or attempt) and 60 per network, refused beyond with
ProfileRefusal.tooManyHandleChecks: profile.checkHandle and saving a
profile with a handle new for the person, simpleLogin.checkHandle and
signUp, keys.set with a handle, and Halkyon Learn's inbox.block and
unblock, which look people up by handle. A person's own handle and what
is no handle aren't counted. The SimpleLogin limiters of commit 3 give
way to it, so a network's 60 are shared between people signed in and
people new. The register's checkHandle, saveProfile,
signUpWithSimpleLogin and setFirstKeys carry the visitor's network from
the member that asked.
Halkyon Learn's handle dialog words the new refusal (English, German).

The `simpleLogin` endpoint on halkyon_oidc's SimpleLogin preset: `begin`
for the app and platform (the state's marker for the forwarding page), at
most 30 an hour per network; `complete` with SimpleLogin's code, signed out
a session for the account with that SimpleLogin ID, signed in SimpleLogin
added to the caller's account, who becomes identified and anonymous no
longer. Someone new gets no account yet: their identity waits 30 minutes
under the attempt's ID (D16), with a handle suggested from their name,
`anna_mueller` (D17), for the sign-up of step 3.
The register alone holds the instance's SimpleLogin app
(`simpleLoginClientId`, `simpleLoginClientSecret`) and exchanges codes; a
member asks it for both steps and issues its own session. `SIGN_IN_WAYS`
says which ways the register offers, the instance's basics and the ways
in carry `simpleLogin`, GitHub links nobody more where SimpleLogin is
offered, and Learn's and Todo's pruning forgets the unfinished sign-ins
hourly. No migration: the tables are halkyon_oidc's, already in place.

Build 21 (v0.18.0) was the release tool/release.sh was kept for, the one

`dart run tool/release.dart learn`. The comments that named the script

SimpleLogin takes only https redirect addresses, each registered exactly,
so the instance's SimpleLogin app registers one page on the register's
web server, /simplelogin-callback, which sends the browser on to the app
that began the sign-in: a 303 to the desktop's loopback (127.0.0.1, a port
per app) or the phone's scheme, chosen by the marker the state begins with
(`<app>-<platform>.<rest>`, the rest 1 to 512 characters of base64url),
from a fixed table, so it sends nobody anywhere else. It forwards the code
or SimpleLogin's error (`deny`) with the state and nothing else, refuses
anything malformed, repeated or not a GET with a page that repeats nothing
it was given, and keeps and logs nothing (no-store, no referrer). It is
built ahead of the sign-in itself so development can sign in through
learn.halkyon.eu's page, which the development app registers too.
Android's assetlinks.json for Halkyon Learn signed with the release key
is answered by the Caddyfile on learn.halkyon.eu alone: the one domain the
project's builds name, and the server knows no app's key. A root test
holds its fingerprint to tool/release/android-certificate.sha256. The
app's intent filter comes with the sign-in; iOS's association waits for
an Apple team ID.
The profile page's language choice and look move to common/web_page.dart,
shared by both pages.

The developer decided on 23 Oct to drop the hand-off to an AI assistant
outside the app, and Claude's connector with it, in v0.19.0, the app and
the server together: build 22 raises minimumAppBuild anyway, so no app
calling the connector's endpoints uses the instance after it. An instance
is to have one way to an assistant, its operator's (ADR 0021, proposed).
The app: the field at the foot of Home, and the button in the Library, on
a studyset and while studying, search the web alone, through the engine
chosen in Settings or Android's own search, with the parts of a card the
person picks; a studyset's name and description are never offered. Gone:
the assistants a question opened in (AiAssistant, AssistantHandOff), the
switch between them and the web, Settings' choice of assistant, Connect
Claude with its route, cubit, repository and gateway, and their texts. A
settings file from before keeps the old keys until the next change of a
setting writes it anew; nothing reads them.
The server: lib/src/assistant/ (MCP, its OAuth, the five tools, connect
codes and tokens), AssistantEndpoint, the daily forgetting of the
connector's secrets (its scheduled call cancelled at start), its lines in
the deletion hook, instance.info().assistantConnectorUrl (nullable, so an
older app reads it as none), and Caddy's forwarding of /mcp, /oauth/* and
/.well-known/oauth-*. The migration drops the connector's five tables,
children first:
DROP TABLE "assistant_token" CASCADE; -- tokens of a connection
DROP TABLE "assistant_grant" CASCADE; -- OAuth codes of a connection
DROP TABLE "assistant_connection" CASCADE; -- a person's connected client
DROP TABLE "assistant_connect_code" CASCADE;
DROP TABLE "assistant_client" CASCADE; -- OAuth clients registered
No other table references them, so CASCADE drops only their own foreign
keys. For the minute between the maintenance run and the switch, the old
server answers the connector with errors and fails to delete an account
(its hook still deletes from these tables); ADR 0022 says so.
BREAKING CHANGE: a connected Claude gets no answer from the deploy on, and
the app no longer opens a question in an AI assistant.
