halkyon_shared's 96f2d14: an operator's DATA_LOCATION and
BACKUP_LOCATION may name a subdivision (ISO 3166-2, US-CA, DE-BY)
besides the EU or a country, and the app adds "(EU)" to a member
country and the country to a subdivision ("Germany (EU)", "California,
United States") under the most specific flag there is. deploy/.env and
the backups' guide say so; a Storage Box is named by its country now.
The package registers its notices (the flags, CLDR's subdivision
names); Learn's own CLDR notice for the world map stays, its
registration renamed to say so.

The instances a device keeps an account on, the first start, the
account switcher, signing in and switching person, the gates that build
the dependencies per instance and per person, and the sync service with
its status, card and banner move to halkyon_app (halkyon_shared, ADR
0014), on halkyon_base's client. Learn supplies its frame (name, word,
icon, theme, launch screen, and the two texts only it can say), its
dependencies, whether the device holds content, and its world map's
country names; every text reads as before. An instance counts only
where its basics name the app `learn`, which learnBase now sets.

Sign-in (anonymous, GitHub, email codes), an account's ways in and its
deletion, the pruning and the instance's basics move into the
halkyon_base module (ADR 0014), which every Halkyon server includes.
Learn configures it in server.dart and deletes its own data with a
person through the module's hook, in the order it did. The identity
tables move unchanged: the migration records versions only. The app
calls the module's endpoints; instance.info() stays as it was.
BREAKING CHANGE: the sign-in endpoints moved into the module, so apps up
to build 20 can no longer sign in or start; minimumAppBuild is 21.
Deploy this only together with the release of build 21.

The theme, Noto Sans, the window sizes and the widgets every screen is
built of move to halkyon_ui (halkyon_shared), pinned to a signed commit
as the sync fork is, so Halkyon's other apps share them. Learn keeps its
own colours (the FSRS ratings, a starred star) as LearnColors beside the
theme, the CJK fonts with their licences, and its launch screen's word

Once the person agrees, the device holds MeCab's IPADIC and the
instance's JMdict and cuts lines as Jisho.org does, so their text never
leaves it (ADR 0012). MeCab comes through mecab_for_dart, whose build
hook compiles it; its tokens are grouped by Ve's rules, written anew in
Dart, with に kept a word of its own. Each word is found as it stands or
as a form of a word, else by its dictionary form, else as the longest
words it holds from token to token; longer words over token boundaries
are offered as before.
The curator packs Ubuntu's compiled IPADIC beside the dictionary files
(curate ipadic, and every update run). The server exports its JMdict
from its tables, so the device finds the same keys and keeps the same
versions, and serves both at /device-dictionaries/, named in
dictionary.deviceFiles('ja') with their hashes; Caddy forwards the path.
The app checks each file against its hash, unpacks IPADIC, builds a
SQLite database from the export on an isolate, and asks the instance
for newer files every 30 days, downloading only what changed. The Watch
screen offers the download once per device with its size (34 MB, some
150 MB once set up); Settings downloads and removes them. Without them,
or should cutting on the device fail, lines go to the instance as
before. MeCab's, IPADIC's and Ve's licences join the licence list.
Every build now needs a C++ compiler; mecab_for_dart holds code_assets
at 1.x.

Parity with Japanese's kanji and kana:
- The characters' tab is named by its language (Hanzi, Hangul & Hanja,
Alphabet), its groups too: HSK levels and the characters in common use
(Hong Kong's grades for traditional ones); Hangul and the Hanja taught
in schools; Greek's letters. Radicals for Chinese and Korean in their
own forms (讠 for 言 in simplified Chinese), none for Greek.
- A character's readings are named as its language names them: On and
Kun, Pinyin, Eum and Hun (음, 훈); a letter means its sound and name.
- How characters are written comes by language: Chinese from Make Me a
Hanzi (its medians in KanjiVG's square, Arphic Public License, a data
file beside the app, never in cards), the Hangul letters drawn by the
curator; a Korean word is written letter by letter (닭: ㄷ ㅏ ㄺ). Words
of alphabets (German, Greek) aren't written by hand.
- A Chinese word's pinyin is typed in a session, tone numbers turning
into marks (ni3 → nǐ); KRDict's levels (초급, 중급, 고급) tag Korean
words; a Korean word's pronunciation shows in brackets ([가치]).
- Smaller: Look up in the composer keeps a noun's article; the Watch
filter names its level list; hints and placeholders by language.

Animelon's way of learning from video, from the person's own Jellyfin
server: connected per device (Settings, or a studyset's Add material ›
Watch from Jellyfin) with a name and password or a Quick Connect code,
over HTTPS only (plain HTTP only to a server on the same machine); the
token stays in the system's keyring. Shows, films and videos tied to a
studyset follow the person in their settings as the server's and the
item's ids alone (settings schema 9), named by the server when shown.
The Watch screen plays the video (video_player on Android, media_kit's
libmpv on Linux and Windows) with the line in the studyset's front
language cut into the dictionary's words with furigana, and the back
language's line beneath; a word tapped pauses the video and becomes a
card with the line and its translation as its first hint, tagged with
the show. The video's words are listed, most frequent first. The sound is
the track in the studyset's language, whichever the file marks default,
and the menu switches it; the subtitles read are a whole track, never a
forced one (which only covers what the sound doesn't say), and captions
for the hard of hearing only without plain ones. The line and its
translation take the video's width in a box of a fixed height, so the
video keeps its size; in the dark theme the video's colours glow around
it, as YouTube's ambient mode, and the words' panel takes the colour of
the episode's picture under the pointer.
A line is cut into words with one request: DictionaryEndpoint.withKeys
looks up every stretch of it that may be a word, as it stands and as
every word it may be a conjugation of, in the new dictionary_key table
(one row per key, indexed; migration dictionary-keys adds the table and
its index, nothing else), which the loader fills beside the entries.
The instance gets the text of each line looked up and keeps none of it,
as the Watch screen says.
Linux builds need libmpv-dev, and the app links libmpv: the snap stages
Ubuntu's libmpv2, makes the update-alternatives links for BLAS and LAPACK
that ffmpeg's speech recognition needs (staging never runs install
scripts), and removes what the GNOME runtime and core24 already hold, as
older copies of cairo, pango and librsvg hid the runtime's from its GTK.

Map questions can now be on the world's countries besides Japan's
prefectures: a new question chooses its map above it.
The world is Natural Earth's 1:50m countries (public domain), as they are
on the ground, one region per ISO 3166-1 code (239; Gibraltar and the US
Outlying Islands from the 1:10m layer, which has them), named in every
language a studyset can be in from the Unicode CLDR (Unicode License v3,
its notice in the licence list). tool/maps/world_countries.py builds it;
the outline code it shares with the Japan script moved to outlines.py,
which still writes Japan's file byte for byte. The 1.8 MB file is parsed
off the screen's isolate.
Picking goes in layers on both maps: on the whole map one taps a group
(a continent, or Kantō, Kansai …; chips name them too) and the map flies
there, then one taps the region; Back returns. A group of one (Hokkaidō,
Okinawa) and what is in none (Antarctica) are picked at once. A country
in two groups (Russia, Türkiye, Cyprus) opens the one nearer the tap.
Oceania's frame runs past 180° so the Pacific stays in one piece.
What is still too small to hit gets a ring, 48 dp of reach as Material's
touch target: on the ring it is picked; near it, where the tap could mean
it or its neighbours, the map zooms in rather than guess. Pinching and a
mouse's wheel zoom as before.
Names show in the app's language, beside them the map's own (Japanese for
Japan) or the studyset's (キプロス beside Cyprus in a Japanese studyset).

A table keeps each row's height on its cells and corrects it after
layout through a transaction, which a read-only editor never applies:
in a path step, a note or a card, a cell of several lines (る, う, つ in
Tae Kim's conjugation tables) ran over its row's borders. Our fork of
the editor now sizes the rows of a read-only table in place, as it
already did the table's height (81c3006c on halkyon/win32-v6; upstream's

KanjiVG's strokes come with the app (assets/kanjivg/, CC BY-SA 3.0, its
notice in the licence list): 94 gzipped files, one per 256 code points,
2.7 MB in all, a file read the first time a character of it is asked for
(StrokeRepository, app-wide beside the maps). The strokes are SVG path
data, read with path_parsing (the Flutter team's, pure Dart, already in
the build through flutter_svg), so the model can flatten them into points
without dart:ui, as checking handwriting will.
A character's sheet traces its strokes in order over those to come, with
its stroke count, meanings, readings, level and the components KanjiVG
splits it into, each a tap away. It opens from a studied character's
answer (Stroke order) and from a character found in the dictionary.

serverpod_offline_sync v0.0.10 collects outbound changes in one
consistent snapshot, so a sync no longer fails on writes made while it
runs (upstream #84, #163), keeps checkpoints per author, so a device
clock moving backwards no longer stalls sync or resends data, and keeps
unique conflicts and foreign key defaults alike on every device. Its
tables and its messages are unchanged: no migration, and apps on v0.0.8
keep syncing. It needs Serverpod >=4.0.4 <4.1.0 (v4.0.4 is fixes only),
so the root overrides that held the workspace on one Serverpod go: each
package pins v4.0.4 itself. The generated code is identical under the
v4.0.4 CLI, which CI now uses.

The studyset sheet gains Languages, as before: off until "Set
languages", then the language of the cards' fronts and of their backs
(22 languages, Chinese in its two scripts). A studyset without its own
takes those of the nearest studyset above it, both together; set for the
first time, they start from those it took. The payload held both fields
already.
They set its text: Noto Sans SC, TC and KR join Noto Sans JP (bundled,
never fetched; 34 MB more, fonts 42 MB in all, your call), and since
Han characters take the shapes of the first font that has them, every
screen inside a studyset (its screen, cards, notes, paths, studying it)
puts the font of its front's language first, else of its back's,
Japanese otherwise. Every studyset route goes through one helper now.

The app brought no fonts: text took each device's own, a minimal Linux
showed Japanese as boxes, and kanji could take Chinese shapes. Now Noto
Sans is the app's font everywhere (Latin, Greek with polytonic,
Cyrillic), and Noto Sans JP fills in kana and kanji in their Japanese
shapes. Noto Sans JP alone wouldn't do: it lacks accented and polytonic
Greek. Both come with the app and are never fetched; scripts neither
covers fall back to the device's own fonts.
Each family is one variable font holding every weight (Flutter sets the
weight axis from the requested weight; a test checks bold inks more):
0.7 MB Noto Sans, 0.7 MB its italic, 8.1 MB Noto Sans JP, from Noto's own
GitHub releases (assets/fonts/ATTRIBUTION.md). Their SIL Open Font
License texts join the app's licence list.

Export content, in the studyset's options, writes the studyset and
everything inside it as one readable Markdown document (decided
2026-10-08: no re-importable archive before the public tier's release
files): its title, secondary title, description and licence, then its
flashcards (answers below their questions, choices as task lists),
notes, learning paths (steps with their kinds, answers, feedback and
sources), PDFs and bibliography, then each sub-studyset a level deeper.
Rich text keeps its formatting; formulas go between dollars, callouts
become quotes, spoilers HTML details, YouTube videos links. With files
(images, sounds, PDFs) it keeps a .zip of the document and them under
files/; a file this device can't have is named and counted.
Saving goes through a FileSaver: file_selector's dialog on the desktop,
file_picker's (Android's Storage Access Framework) on phones, a direct
dependency now at the version the editor already brings.

Home has a Pomodoro timer (decided 2026-10-07, after Goodtime): the
profile it runs, chosen there while no timer is set, the time left of
the phase, and Start, Pause or Resume, Skip and Stop. While studying, a
small countdown sits in the study screen's header, and a tap pauses it
or goes on. A phase that ends leads to the next, which starts by itself
where the profile says so and otherwise waits, paused at its full
length.
Profiles follow the person to every device, in their settings (schema
4, still written as schema 3 while the profiles are as they come, so
older apps go on reading the settings): Classic, 25 minutes of focus,
5 of break and 15 after four, and 52/17 without long breaks, built in;
both can be changed, more added and deleted, from Home's card or from
Settings. A profile can start breaks and focus by themselves, and keep
the device quiet while focusing. The running timer is the device's own,
kept in the person's folder: closed and opened again, the app catches
up with the phases that ran out meanwhile.
Android: the app's own foreground service (Kotlin, specialUse, as
Goodtime does) shows an ongoing notification counting the phase down,
with Pause or Resume, Skip and Stop; on Android 16 it is a Live Update,
its progress bar the profile's cycle, each phase a segment, focus in
cobalt and breaks in copper. An exact alarm (USE_EXACT_ALARM) alerts
with sound and vibration when the phase ends, also with the app
closed, and Do Not Disturb goes on while focusing once the person
allowed it, the filter before given back afterwards. No notification
plugin: flutter_local_notifications has Live Updates only in a
prerelease that needs compileSdk 37; androidx.core 1.18, which the
build resolved already, has every API needed.
Linux, over the session bus (package:dbus, already in the build): where
the desktop shows icons in its top bar (GNOME with the AppIndicator
extension, which Ubuntu has built in; KDE) the timer counts down there,
the buttons in the icon's menu, as a StatusNotifierItem written in Dart
on the names and paths the snap's desktop plug allows; elsewhere a
notification with the buttons says until when the phase runs. An alert
with sound ends each phase while the app runs, and GNOME's banners stay
off while focusing, through gsettings. xdg-desktop-portal's Background
status, the planned fallback, serves Flatpaks only.

The launcher showed Flutter's logo: the project template's icons were
never replaced. tool/app_icons.py now makes every icon from the
kingfisher (assets/icon/halkyon_icon.png), through flutter_launcher_icons
v0.14.4 configured in the app's pubspec: Android's adaptive icon (the
kingfisher inset 16 % on white, for each launcher to cut to its shape)
and the square one before Android 8; iOS's, without transparency;
macOS's, the rounded tile on Apple's grid (824 of 1024 pixels); and
Windows', the rounded tile, its .ico with every size from 16 to 256
pixels (the tool writes only 256). It keeps the iOS project file as it
was, which the tool would break (flutter_launcher_icons issue 634), and
writes the snap's icon as tool/snap_icon.py did, which it replaces.
The Linux runner gives its window the bundled icon too, for desktops
that don't take it from the desktop file.

snap/snapcraft.yaml builds the Linux app as a strictly confined Snap on
core24 with the GNOME extension (GTK, WebKitGTK, GStreamer and libsecret
come from its runtime; files and the browser go through the desktop's
portals), connecting to learn.halkyon.eu, the project's instance. It
builds what is committed, with Flutter pinned as in CI.
- The session: libsecret's keyring over D-Bus needs the
password-manager-service plug, which the Store never connects by
itself, so unless it is connected the app keeps the session in an
encrypted file whose key comes from the Secret portal
(snap/local/secret-backend).
- network-manager-observe lets Serverpod hear that the network went and
end the sync's connection at once; until the Store grants it, it too
is connected by hand.
- The listing points to the project, not the instance: the website
learn.halkyon.app, contact and issues support@halkyon.app.
- The icon is the app's with rounded corners (tool/snap_icon.py), for
the Store and the dock alike.
- The app's version is 0.1.0, build 1.

Published apps can't be made to update, so the app now notices when it
no longer matches the server: the server names the oldest app build it
works with (instance.info's minimumAppBuild), asked before the first
sync of each launch, and the sync engine's refusal of differing synced
tables counts the same. Either way the app says "update the app; if it
is up to date, the server needs an update" in a banner on Home and in
the new Sync card in Settings, and what the person does meanwhile stays
on the device.
The Sync card shows where sync stands since the app started (syncing,
everything synced, sync failing, with the last completion and failure)
and offers Sync now. While the last sync failed, a dot sits on the
Profile tab and the Settings cog. One sync that goes through clears it.

PDFs live in a studyset's new Files tab: uploaded from Add material
(a file the studyset holds already asks first), each row with its
pages, cards, notes and size, how far it is read and its reading
deadline; renamed, given a deadline (a page or a chapter by a day),
marked as read, started afresh, deleted with a moment to undo.
The reader (/pdfs/:id) opens where reading left off: on wide windows
a rail of tools (search, fit, zoom, fullscreen), a page counter with
the chapter, and a sidebar; on phones a top bar, a page scrubber and
a sheet. The sidebar holds the PDF's flashcards, by page or chapter,
made from selected text or written there, each tied to its page and
tagged with its chapter; and the page's note, an ordinary note tied
to the page. Screenshots of a region become images that know their
page. Cards and screenshots lead back to their page; reading on past
a chapter with cards suggests studying it. Home shows the deadlines
running and to come, and a timeline of them.
Server: pdf_source rows (content in the payload, last writer wins)
and an append-only pdf_reading log, the furthest page derived from
it so devices never conflict. Files up to 50 MB for PDFs (20 MB for
others; a larger file that isn't a PDF is deleted once stored). A
deleted PDF takes its file's asset row along unless another PDF has
the same file. Card payload 4 and note payload 2 keep the page.
The reader draws with pdfrx (PDFium) behind PdfEngine in
Dependencies; widget tests use a fake, and
integration_test/pdf_engine_test.dart checks the real engine on a
device or the desktop.

Blocks beyond the editor's own, each built once for editor and view:
- callout: eight kinds in theme colours, kind, title and "folded at
first" from its header; written in place, left with Enter on its
empty last line; never inside another
- spoiler: written in plain sight, hidden behind Reveal read-only
- formula on its own line, written on its own screen with a preview
and snippet buttons, and formulas within a line (Σ in the format
bar); set by flutter_math_fork behind MathView, LaTeX's numbered
environments read as their aligned forms
- image and sound picked from the device, kept as synced files
- YouTube video from its link, with its start and a caption: a card
until played, nothing fetched before; played in place where a web
view exists (youtube_player_iframe, privacy-enhanced), else opened
in the browser, behind YoutubeVideos in Dependencies
- study button: a studyset, a tag or all cards, with or without its
topics, back first; its StudyFocus rides on the study route and
narrows that session only
- tables, already in the editor, now insertable everywhere
An Insert button opens on the format bar, so blocks can be inserted on
phones too; the desktop's / menu lists the same blocks, translated.
Card faces now dock the format bar while written, so cards get blocks
and formatting on phones as well. The blocks are listed in
EditorBlocks: the core's, plus the features' through
EditorBlocksScope. Blocks of a type the app doesn't know say they need
a newer version and stay as they are, so formatVersion stays 1.
Their types and keys are in content_blocks.dart, which RichContent
reads: a block's text counts as text, and a video or study button
isn't blank. The path import now makes formulas real ones.
integration_test/youtube_player_test.dart plays a real video through

refuses embeds that don't say where they are embedded.

Files in content: the person's images and sounds as asset rows synced like
all content, their files kept by hash on each device, uploaded after each
sync, downloaded on demand and checked against their hash
(core/asset/AssetRepository). Rich text names them as asset:<id> URLs, in
the editor's image block and an audio block of ours; any other URL is never
fetched. Sounds play through audioplayers, one at a time. Content holding
only an image or a sound isn't blank, and lists show it as such.
The Anki import ("Import from Anki" under Add material): .apkg and .colpkg
packages in all three formats Anki has written, read on an isolate of their
own. Modern packages compress everything with zstd in frames that don't
record their size, which pure_zstd v1.0.0 refuses; our fork decodes them.
Fields become rich text by a converter of our own (lines, lists, formatting,
images, sounds, cloze deletions hidden on the front). One card per note,
the files first, studysets as chosen (flatten, sub-studysets, or tags by
subdeck), the notes' tags, and, if wanted, the review history, which FSRS
replays: the first template's reviews to the card's schedule, a reversed
note type's second to the reverse one.
Imported cards say where they came from in their first revision (card
schema 3); the dashboard doesn't count them as written. The test fixtures
are exported by Anki itself (tool/anki/make_fixtures.py).

A map question is a multiple-choice card drawn on a map: the composer's
Map kind takes the region tapped as its answer, and studying it means
tapping a region and checking, the right one green and a wrong pick red,
each named. The map of Japan's 47 prefectures comes from Natural Earth

The app gets its look and navigation before more features land on them.
- Theme (core/theme/): hand-written light and dark Material 3 colour schemes around
cobalt and copper; ThemeExtras for the colours Material has no role for (states, the
four FSRS ratings); the 20 colours a person can give content. Tests hold text to WCAG
AA contrast on each palette colour and on the dark theme's primary colour and surface.
- Layout and shared widgets: Material 3's window-size classes (core/layout/);
SectionCard, AppLoadingIndicator, confirmDestructiveAction and FoundById
(core/widget/). Lucide icons.
- Navigation with go_router: four tabs (Home, Library, Explore, Profile), each keeping
its own stack of screens, as a navigation rail with the app's icon from 600 dp and as
a navigation bar below; choosing the open tab again returns to its first screen. A
studyset's screen sits in the library; studying, cards and settings cover the tabs.
- Routes carry ids: FoundById finds the item in the repository's live list, so a
studyset deleted on another device, or an old link, says it no longer exists. A
screen that deletes its own item keeps showing it while it closes, rather than
flashing that message.
- Every person gets an app of their own (PersonApp, lib/src/app/): a
MaterialApp.router with its own GoRouter and PersonScope around the navigator, built
by SessionGate inside the person's keyed subtree. Screens read the person's
repositories wherever they are built, so the static route() helpers and the listener
that closed every pushed screen on a change of person are gone: a change of person
now disposes the whole router and starts again at home.
- The account dialog becomes the Profile tab, with Settings (sign out, delete the
account, About) behind a gear. A waiting GitHub sign-in now keeps waiting while
another tab shows; a change of person still cancels it.
- The new screens' strings come from Flutter's gen-l10n (English for now). The
generated files are committed, left out of analysis and formatting, and written
anew by `flutter pub get`, so CI's check of generated code also catches stale ones.
Widget tests now start the whole app (test/support/pump_app.dart) at the screen's path
and move through it as a person would, by tabs and taps.

The schema of the features planned for the first release, as one migration: every
migration of a synced table locks older app versions out of syncing (ADR 0002, rule 3),
which costs nothing before that release. New card types need no migration; they are the
next version of the revision payload.
- studyset: `parent` (the tree; cycles and orphans show at the top level) and `position`
among siblings (fractional index; existing studysets at 'a0').
- tag (its name in the payload) and card_tag, one row per assignment, so concurrent
adds and removes merge.
- review_log.mode: review, reverse (a schedule of its own) or cram (never moves a
schedule); existing reviews are 'review'.
- person_settings: study goals now, preferences later; random ids, since an id derived
from the person could be claimed by someone else and break the owner's sync.
- asset: a file's hash, type, size and name; the file goes into Serverpod's private
cloud storage, served through an owner-checked endpoint (to come).
Migration 20260930211154224-tree-tags-assets only adds: four tables with their space
indexes and foreign keys, three columns with defaults. On devices SQLite rebuilds
studyset and review_log to add foreign keys, which is safe only with foreign keys off,
as Serverpod's runner does; a new test replays every client migration on a database
with a row in each of our synced tables and checks that none is lost (with foreign keys
on, it fails as it should).

The app took the editor from our fork of AppFlowy Editor in a folder next to the
repository, which nobody else had, and which CI can't reach either. The fork now lives at
https://code.halkyon.app/project-halkyon/appflowy-editor (public; dual-licensed AGPL-3.0
or MPL-2.0 like upstream), on its branch halkyon/win32-v6, and the app depends on it by
git URL, pinned to the signed commit 0dac8a0. That commit adds `publish_to: none` to the
fork: it is a git dependency only, and the package name belongs to AppFlowy on pub.dev.

Signing in with GitHub on Linux ended in "Unable to connect" at 127.0.0.1:43823 after authorizing. flutter_web_auth_2 (v5.1.0, unchanged on its master) ends every pending sign-in when the app is resumed. That suits mobile, where coming back without finishing means giving up, but on the desktop the window regaining focus resumes the app, and the package's loopback server closed before GitHub sent the browser back. FluffyChat's issue #3341 and the package's #171 report the same.
The app now puts its own Linux and Windows implementation behind the package's platform interface (LoopbackWebAuth): the system browser and a loopback address, as RFC 8252 recommends, waiting until GitHub answers, the person cancels, or five minutes pass. It listens on 127.0.0.1 only and answers only the callback's path. Serverpod's PKCE and state check stay in use. There, the account dialog shows "Continue in your browser." with a Cancel button, and closing the dialog cancels the sign-in.
Serverpod (v4.0.3) reports a cancelled browser round trip as an unknown error, so the gateway knows a cancel by having asked for it. A cancel on GitHub's own page, or leaving the browser on Android, still reads as a failure; AGENTS.md says so.
The regression test drives the package's front through a change of focus. With the package's behaviour it fails with the same refused connection.

A studyset's card list gains "Study". The study screen shows the front, then the answer and the four ratings, each labelled with when the card would come back; every rating is recorded with how long answering took, and the queue is worked out anew after each.
Schedules are never stored: scheduleOf replays a card's reviews in time order with FSRS-6 (fsrs v2.0.1, pinned exactly so every device on one app version computes the same). The package's fuzz can only be seeded through an API meant for tests, and due dates don't feed back into a card's state, so the replay runs without fuzz and fuzzedDays spreads the final due date over FSRS's range, picked by a stable FNV-1a fraction of the card's id and review count. studyQueue takes due cards earliest first, then new cards in studyset order, 20 per studyset and local day, and brings a learning card due within 20 minutes early when nothing else is due. Deleting a card deletes its reviews.
Tests: the replay (learning, growing intervals, the same schedule whatever order reviews arrive in, previews matching what a rating yields), the fuzz range, the queue (order, the daily limit counted per local day, learn-ahead), the repository, the session bloc under a controlled clock, the screen, and a sync test for ratings on two devices. AGENTS.md records the review log and scheduling, and how plugin lint rules are ignored.

A studyset's screen lists its cards (reorderable; a marker on cards changed on two devices) and opens a card's screen with an editor for each side. Saving appends a revision whose parents are all current heads. mergeRevisions merges several heads per side against their newest common ancestor, as decided: different sides merge automatically, the same side changed differently is a conflict. The card screen then shows every version of that side with "Keep this", and saving is possible once each conflicted side is settled, which resolves the conflict for every device. Nothing is merged silently inside a side.
CardRepository watches a studyset's cards, creates at the end and moves by fractional index (fractional_indexing_dart, checked against the reference algorithm's test vectors), and deletes by blanking every revision first (ADR 0002, rule 2). Deleting a studyset now deletes its cards the same way before the studyset goes. Every person gets a CardRepository whose revisions name them as author. RichContent gains plainText for the list's previews.
Tests: the merge (chains, different and same sides, conflicts, resolving, three heads, missing parents, arrival order), the payload, the repository against a fake gateway, both blocs, and the widgets, including that cancelling a delete keeps the card. The sync tests, which need the running server, cover merging and conflicts across two devices and blank revisions on the server; their device helper is now shared in test/sync/support. AGENTS.md describes the revision pattern, the fractional order, and two tooling traps.
