refactor(app,learn): people's files on the device shared in halkyon_app
ADR 0043's recommendation, for Todo's attachments: what Learn had for its
files on the device moves into halkyon_app, unchanged but for its names,
and Learn uses it from there.

- FileCache, DirectoryFileCache (Learn's AssetFileCache): the files by
  their SHA-256 in a folder of the person's, and which wait to be
  uploaded.
- FileServerGateway, ServerpodFileServerGateway (Learn's
  AssetServerGateway): halkyon_base's files endpoint, taking the module's
  caller rather than Learn's client; FileLimitReached, FileRoom.
- Their fakes in halkyon_app's testing: MemoryFileCache,
  FakeFileServerGateway, sha256Of.
- SealedFile: the format every app seals a file in (HLKF, version 1),
  sealing with halkyon_app's ContentCipher; Learn's Privacy seals and
  opens its files with it, for the same context as before, so every file
  sealed so far opens as it did.

refactor(base,learn): people's files kept by halkyon_base
ADR 0043, D2, D4, D6 and D7, the first step towards Todo's attachments:
Learn's file store moves into the module, for every server that keeps
files, and Learn becomes its first host.

halkyon_base gets the store as Learn had it: uploads into the caller's
own space by SHA-256, downloads by a row the caller may read, each
person's room (FILE_LIMIT_IDENTIFIED_MB, FILE_LIMIT_INSTANCE_MB, the
operator's file_allowance, which moves into the module unchanged) and
the pruning of files no live row names. It stays free of the sync
engine: a host hands it a FileStore saying which of its rows name a file
and what it takes (HalkyonBase.files); without one the files endpoint
refuses. Its tests, with refusals, run on a stand-in host.

Learn hands it learnFiles: its asset rows, read by their space's members,
a readable file over 20 MB only as a PDF, up to 100 MB. Its app calls the
module; its own asset endpoint stays for released apps alone, forwarding
to the module in Learn's own models, whose names are on the wire. Its
file tests still pass through it, end to end.

Migrations: the module's creates file_allowance. Learn's server migration
holds version rows alone, as tables are matched by name (ADR 0014); its
device migration creates the module's empty table, as every module's.
Todo's, Train's and Meditate's create the empty table.

feat(app,ui): sync waits on mobile data and asks first
The developer's request of 10 Nov 2026, decided in ADR 0042: on mobile
data every app holds its sync back, rows and files alike, and asks.

halkyon_app becomes an Android plugin, its first native code, registered
in every app by Flutter: HalkyonAppPlugin.java says which network the
device is on and whether it is metered as Android has it (no
NET_CAPABILITY_NOT_METERED: cellular, a phone's hotspot, Wi-Fi marked
metered). Java, so it applies no Kotlin Gradle Plugin.

MobileDataGate, one per device, holds the setting (Ask first, Sync
without files, Sync everything; kept in <app support>/mobile_data.json),
the network, and the person's answer, which holds until the device moves
to another network or off a metered one. SyncService asks it before each
sync: held back, nothing goes, the status counts what waits and asks; an
answer or Wi-Fi syncs at once, and syncing now while held back is Sync
now. Each app's frame shows the banner above every tab, in halkyon_ui's
new NavigationFrame.banner slot (On mobile data · 3 changes waiting, with
Not now, Without files and Sync now); the Sync card in Settings chooses
the setting on a phone and says when files wait for Wi-Fi. Learn's files
neither go up nor come down while held back.

Whats-New: On mobile data the app no longer syncs by itself: a banner asks first, and Settings › Sync chooses whether to ask, sync without files, or sync everything.
Whats-New-De: Mit mobilen Daten synchronisiert die App nicht mehr von selbst: Ein Hinweis fragt zuerst, und unter Einstellungen › Synchronisierung wählst du, ob sie fragt, ohne Dateien oder alles synchronisiert.

feat: the rail opens into a sidebar with labels from expanded windows on
Decided by the developer on 9 and 10 Nov 2026: phones keep the bar,
medium windows (600 to 840 dp) the rail alone, and from 840 dp a toggle
at the rail's foot opens it into a sidebar 256 dp wide, as Proton
Drive's: the app named beside its icon, each tab its label beside its
icon, the icons where the rail had them, so nothing moves under the
pointer. Its labels come in one after another, top to bottom, all at once
where animations are off. Open or closed is kept per device, in
halkyon_app's Look (look.json, `sidebar`), which Learn keeps in its
DeviceSettings (`sidebarOpen`), as it does the appearance and language.

NavigationFrame takes sidebarOpen and onSidebarChanged (no toggle without
it), and sidebarSections, what the app lists below the tabs, which Todo's
favourites and projects will be. The closed rail keeps Flutter's widget,
its toggle pinned at the foot (trailingAtBottom); the open one is the
frame's own, as the staggered labels need. Learn, Todo, Train and
Meditate keep the choice.

Whats-New: In wide windows, the button at the foot of the side rail opens it into a sidebar with names, and it stays open.
Whats-New-De: In breiten Fenstern öffnet der Knopf unten an der Seitenleiste sie mit Namen, und sie bleibt offen.

feat(ui): on a phone, the floating button sits just above the navigation bar, its screen's fade under it
Each tab's screen paints the bar's fade beneath its own button
(FrameFade as its bottomNavigationBar, extendBody), so the button stands
16 pixels above the bar, as Material's, instead of above the fade; the
frame keeps its own fade for screens without one, and gets it back while
a page is pushed over the screen.

feat(ui): in dark mode, filled and floating buttons in cobalt itself, white on it
In dark mode the primary colour is cobalt lightened (#AEB9FF), readable as
text and thin marks on the dark surfaces, and filled buttons took it: Todo's
send button glared bright beside everything else; floating buttons took
Material's dark primary container. Both are cobalt itself now, white on it,
as in light mode (decision 6 of the developer's list, 9 Nov 2026); links,
tabs and switches keep the lighter tone. Filled icon buttons take no theme
of their own in Flutter (the icon buttons' theme is the plain ones' too),
so they take filledIconButtonStyle: Learn's study and send buttons,
Todo's send buttons and Locate me, Meditate's stop dictating.

Whats-New: In dark mode, filled buttons and the + button are cobalt with a white icon, no longer a bright light blue.

feat(ui): Profile's tab row slides back in on any scroll up, the tab's name fading under the title
FoldingTabs, as Strava's Groups (the developer's review, 9 Nov 2026):
the tab row is a floating header now, following the finger out as the
content scrolls down and back in as it scrolls up however little, wherever
the content is; before, it came back only at the top. Folded is read from
how much of the row shows. The chosen tab's name fades in and out under
the title as its room opens and closes, where it appeared at once: the
title keeps one tree folded or not, as a tree changing under it made its
switcher start over without a fade.

Whats-New: Profile's tabs slide back in as soon as you scroll up, and the tab's name fades in under the title as they go.
Whats-New-De: Die Tabs im Profil gleiten zurück, sobald du nach oben scrollst, und der Name des Tabs blendet unter dem Titel ein, wenn sie verschwinden.

feat(todo): quick add's keys, sub-projects' colours, a task's menu on a right click, and the completed tasks deleted at once
The developer's list of 9 Nov 2026, Todo's part:

- Quick add: the down arrow and Tab move into the description, with its
  cursor (halkyon_editor's fix); Escape closes the projects or labels
  suggested first, then closes quick add, what was typed discarded; the
  project's chip shows the project's colour.
- A project without a colour of its own shows its parent's, the nearest
  ancestor's with one (colorOfProject, TodoCubit.colorOf), wherever a
  project's colour shows; the project editor's "Same colour as its parent"
  keeps it so, and the parent picker shows each project in its colour. A
  project of its own always has one.
- The task pane's x closes it, always; Close left the ⋮ menu.
- A task's row opens its menu on a right click: Mark as done, Date, Move
  to, Labels, Priority, Deadline, Duplicate and Delete, the selection's
  actions for that one task.
- Delete completed tasks, in the ⋮ of the Inbox, Today, Upcoming and a
  project, with Undo: the tasks leave the list at once and are deleted
  once the snack bar goes without its Undo (halkyon_ui's showUndoSnackBar
  gains onKept).

fix(ui): on a phone, a snack bar stands above the screen's floating button
Below medium windows the frame's scaffold showed the screens' snack bars,
under the floating button of the screen's own scaffold, so a tap on a
snack bar's Undo hit the button instead (found 9 Nov 2026, Todo's Undo
after deleting the completed tasks). The screens get a messenger of their
own there, and their scaffolds lift the snack bars above their buttons, as
Material places them. From medium windows on the frame's scaffold still
shows them, once: a messenger shows a snack bar on each of its scaffolds
not inside another, as two panes side by side are. As the window grows
past a phone's, the phone's snack bars go, since a scaffold whose
messenger changes keeps the one it showed for good.

Whats-New: On a phone, a message's Undo is no longer hidden under the + button.

feat(learn,todo,meditate): dictate through the phone's voice input app (ADR 0038, D18)
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).

refactor(ui,learn,todo,train,meditate): the navigation bar's one look, the debug section gone
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.

feat(ui,learn): the navigation bar in the colour of the screen in view
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.

feat(ui,learn,todo,train,meditate): a wave in the app's colour over the navigation bar
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.

feat(learn,todo,train,meditate,ui): the navigation bar flush with the foot, a fade above it
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.

fix(todo,ui): Today's day centred in its calendar, and the way back to today shows it
Today's tab drew its day centred at 16 of the calendar's 24 units, where
Lucide's SVG has its body's middle; its font draws the calendar a unit
higher (the top bar's stroke from 8 to 10, the foot's from 20 to 22,
measured with the real fonts), so the digits sat a unit and a half low.
halkyon_ui's new DayCalendarIcon centres them at 15, in Noto Sans set
explicitly, and its tests draw it with the real fonts at 16 to 32 pixels:
the digits centred in the body within half a unit, and 10, 20, 28 and 31
clear of the sides. Todo's TodayIcon keeps the midnight redraw around it.

InsertableBlock's name takes the BuildContext. Learn's screens use
LearnContentEditor and LearnContentView, which add Learn's blocks and the

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.

fix(learn,ui): the open assistant field holds still: no flicker, no sliding away, no resizing under the keyboard (ADR 0021, D69)
Inside a studyset the field flickered as it opened and closed: the
floating location switched between a raised centre and the centre,
which Scaffold animates by scaling the button out and in. It keeps one
location now, raised above the licence line by padding. While open it
no longer slides away as the studyset or the Library scrolls
(ScrollHidingFab.pinned, new), and the keyboard covers Home, the
Library, a studyset and a session rather than shrinking them; the field
lifts itself by as much of the keyboard as reaches above it.
NavigationFrame no longer resizes for the keyboard itself, leaving it
to each tab's own scaffold, which still does by default (Todo's,
Train's and Meditate's tests pass unchanged).

Whats-New: Inside a studyset, the question field opens without flickering, stays while you scroll, and the screen no longer jumps when the keyboard comes.
Whats-New-De: In einem Lernset öffnet sich das Fragefeld ohne Flackern, bleibt beim Scrollen stehen, und der Bildschirm springt nicht mehr, wenn die Tastatur kommt.

feat(learn,app): the field's row as one, its model by name in its provider's colour, the microphone dictating (ADR 0021, D69)
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.
Whats-New: Who answers shows the model's name, in its provider's colour.
Whats-New: The microphone keeps listening after a pause, writing where the cursor is, until you stop it.

fix(app,learn,meditate): a device without speech recognition says so, and how to get one
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.

Flutter's clipboard. Emptied 60 seconds later if the clipboard still holds

refactor(app): the device's speech recognition moves from Learn into halkyon_app, with dictation into a text
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.

feat(meditate): Meditate's server, its sealed tables, and SimpleLogin's way back to it
halkyon_meditate_server and its generated client, copied from Todo's
and stripped to the module, the register and the sync engine (ADR 0038,
D1, D7): content_key, meditate_settings and sitting, synced and sealed,
each indexing spaceId and deleted with the person's space; two
migrations, the initial one and sittings (purely additive, the ADR
explains the SQL); ports 8280 to 8282 and PostgreSQL 8290 (D13).
Tests: the module's basics naming `meditate`, the sync engine refusing
calls without a session, the register's modes, and a person's deletion
taking their rows alone.

halkyon_base's forwarding page knows Meditate's ways back
(meditate-loopback on 43826, meditate-scheme app.halkyon.meditate),
which halkyon_app's repository names among the apps' ports.

build(deploy)!: the instance's compose file is compose.learn.yaml, beside compose.train.yaml and compose.todo.yaml
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
compose.learn.yaml, before the link goes.

build(todo): Todo deployable beside Learn's server, and released as an APK, on F-Droid and as a snap (ADR 0033, step 5)
deploy/compose.todo.yaml adds Todo's server at todo.halkyon.eu, a member
of Learn's register, its database halkyon_todo in the instance's
PostgreSQL, its image built as Train's. redeploy.sh and backup.sh go over
every app server .env switches on (train, todo). Each compose file names
its server to the register in a variable of its own
(INSTANCE_MEMBER_TRAIN, INSTANCE_MEMBER_TODO), which halkyon_base adds to
INSTANCE_MEMBERS, each address once, as a second compose file's default
would have replaced Train's.

apps/todo/release.dart configures the release tool for Todo's APK and
snap: a key of its own (pinned once made; until then nothing is
released), the F-Droid listing (Time, NonFreeNet), and the snap from
apps/todo/snap/, which the tool builds in a clone of the repository at the
tag with that folder in place of snap/, as snapcraft builds one recipe a
folder and the root's is Learn's. What's new for 0.1.0 in English and
German, now shown. Android's backup and transfer are off, as Train's
(D53): the reminders scheduled keep their tasks' titles unsealed.

feat(app): one Profile for every app, the person's own tab first, then each app's (ADR 0014)
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.

feat(learn): Explore by what a licence allows, a skeleton while the library loads, and an assistant's agreement per provider (ADR 0005, rule 12; ADR 0021, D66)
- 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
  person has a private studyset.
- 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.
