"More info", in a card's menu while studying or in the list, shows when
it was made and last changed (its ids say), its id and its studyset's

and when last. The sheet is a shared one, for notes and paths to follow.

A word with senses (as a dictionary gives them) shows them when its
answer shows: numbered when there are several, each with its label, its
translations and its grammar codes, small and slanted, their meaning on
hover. A word usually written in kana shows its reading from the start:
its kanji are rarely seen, so there is nothing to hide. The composer
writes the senses' translations, adds and removes senses, and keeps the
codes as they came.
The codes' short forms and meanings are the dictionary's own English
(JMdict's entities), kept as data beside the cards.

- "Report an error", from a card's menu while studying or in the list:
a category (typo, grammar, content, other) and a note. The card is
marked to be fixed, and still studied; the list shows the category
(the note on hover), and "Resolve report" takes it back. A report is
a revision of the card, so it follows it to every device.
- The list buries a card until tomorrow and brings it back ("Unbury"),
showing "Buried" meanwhile.
- Each of these says so with an Undo.

A card of any type can carry up to six hints and an explanation, both
rich text. They are written in the composer, added from its menu (or
Ctrl+Alt+H / Ctrl+Alt+E), each removed on its own; blank ones aren't
kept. While studying, "Hints" under the question opens them one at a
time, and "Explanation" comes with the answer.
Card schema 5 holds them (`hints`, `explanation`), and with them what a
card needs next: a report that something on it is wrong (`report`:
category, note, when) and a word's senses with their grammar codes
(`senses`; a word's meanings then come from them, and its first sense
says whether it is usually written in kana). Each merges as a field of
its own.

"Bury until tomorrow" in a card's menu sets it aside for the rest of the
local day: it leaves the round, and no session or count takes it until
the next day begins; its schedule stays as it was. Undo, offered for a
few seconds, brings it back into the round.
A burial is an entry of its own in the review log (mode "bury"), as a
fresh start is: no synced table changes, older app versions skip it as
a mode they don't know, and it never counts as studying.

The study session, reworked:
- Ratings are coloured tiles with a face each (frown, meh, smile,
laugh), when the card comes back below them with a clock ("in 1
min", "in 3 days"), always shown, so a card can be rated without
revealing it; at most 540 dp wide, centred.
- Cards are centred in a section card: the question large, then a line
with 24 dp on either side and the answer a size smaller, or "Show
answer" 40 dp below; a tap anywhere on the card shows or hides the
answer. Read-only rich text takes a text style and an alignment.
- Words show their reading small above the expression once answered,
and several meanings numbered.
- Choice, matching and map cards: Check below the card, the ratings in
its place once checked; options marked before their text; matching
lists the categories first, then what is left to place; the map
fills the card with one caption below it.
- Header and progress on a band of their own; title start-aligned,
the Pomodoro timer only to watch, the back-first toggle in every
state; leaving a round under way asks first.
- Cramming goes round the round; back is there with two cards or more,
skipping always.
- The end of a round: the cards done of those due, accuracy (OK counts
half) and time, over the whole session.

A source is now shared by learning paths and studysets (core/citation/):
authors as full names, year, title, what it is a part of, publisher,
ISBN, link, and a citation kept as a file brought it. formatCitation
cites it in APA 7, MLA 9 or Chicago 18: it inverts and abbreviates
names itself (particles, suffixes, names written as already cited stay),
sets a work of its own in italics and a part of something apart from
the whole, and writes a missing year as "n.d." in APA and Chicago.
- Settings: a Citations card per device, with a preview and a link to
the style's own guide.
- Studysets: a Bibliography button opens the works cited, to read and,
behind its pencil, to change (studyset schema 4).
- Steps: sources edited through the same sheet, opened from an
"N sources" button in the runner (step schema 2; schema 1 reads on).

Found on the Pixel 9a with v0.2.1:
- Do Not Disturb while focusing: switching it on opens Android's list
of apps with Do Not Disturb access; once the person allowed it there
and came back, the switch was still off, saying the app may not, and
had to be switched on again. The profile's sheet now looks again when
the app comes back, and the switch goes on by itself once allowed.

From the snap, nothing showed in the top bar: AppArmor refused the
item's bus name (dbus_bind org.freedesktop.StatusNotifierItem-<pid>-1),
which snapd's desktop plug doesn't grant, contrary to what the research
found. The item is now laid out as libayatana-appindicator lays itself
out, within what snapd v2.77's desktop-legacy plug allows: at
/org/ayatana/NotificationItem/halkyon_learn, the only path from which
the label's signal (XAyatanaNewLabel) may come, and registered with the
watcher by that path under the connection's own name, binding no name
at all. Checked against GNOME's watcher here: it registers as the

Found on the laptop: the outlines at a sheet's left (a text field, the
round buttons) were shaved by half a pixel, and the scrollbar lay over
the fields at the right. The sheet's room at its sides was around its
scroll view, so the body's outlines lay on the scroll view's edge: a
scroll view cuts what it holds there, an outline's outer, antialiased
half pixel included, which shows wherever the edge falls between two

scrollbar runs along that edge. The room now lies inside the scroll
view, and the title and the footer keep their own.

alone, and no notification stands in for it. The Pomodoro card says
that the timer can count down in the top bar, with a button that asks
GNOME Shell to switch the extension on where it is installed or to
install it (GNOME's own dialog), or opens its page on
extensions.gnome.org where Shell can't be asked; until the person says
not to suggest it again. An app can't install or switch on a Shell

A review of the timer found:
- Stop in the notification with the app swiped away took the timer
away there, but the app showed it again at its next start. The
service now leaves a mark the app takes when it starts, and the timer
it kept is forgotten.
- Pause, Resume and Skip did nothing with the app gone: since Android
12 a service may not start an activity from a notification's button.
The notification is posted again with buttons that open the app.
- A timer kept while the app was closed was shown as it was before it
caught up, so its ended phase alerted a second time. It is now caught
up before it first shows.
- Dart's timers sleep with the device, so a phase that ended while the
phone or laptop slept went unnoticed until the app came back. While a
phase runs the timer looks every 15 seconds, and on Android the
alarm's receiver wakes it too.
- On Linux, changes that came at once overlapped on the bus (an
indicator registered twice, notifications left over, a ticking label
never stopped); they now go one at a time. The indicator registers
again when GNOME's watcher restarts, and with a watcher that only
turns up later.
- Changing the running profile could put the timer outside its cycle
("Focus 6 of 4", the Live Update's bar past its end); where it is
stays within the new cycle, and a phase waiting at its full length
takes the new length. A countdown past its end shows 00:00.
- Writes of the kept timer go one at a time, and a closed timer arms no
more timers.
- The alert no longer renames the timer's notification channel, and a
German hint said the alert came at the device's end.

A review found three edges of the study options:
- Saving a studyset's study options without changing anything wrote
the defaults as its own, so it stopped following the person's new
cards a day and was written in the newer schema older apps skip. It
now keeps no options of its own.
- The library's badges read the person's new cards a day only when
something else changed; a change to the setting now refreshes them.
- A person's random order shuffled the whole round, undoing the
studyset's Reviews first or New first. The reviews and the new cards
are now each shuffled, the order between them kept.

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.

A studyset's options in the library now offer, as on its own screen,
Edit, Move to…, Study options, Import from Anki, Archive and Delete.
Moving goes through the same sheet and says where the studyset went;
importing reads an Anki deck into it as Add material does.
Study options say how a studyset is studied, on every device: how many
new cards it starts a day (by default as the person's study settings
say), how many reviews it brings a day (no limit by default; cards in
their learning steps come anyway), and whether reviews or new cards
come first, or the new ones spread evenly among the reviews. They live
in the studyset's payload, schema 3; a studyset without them is still
written in schema 2, so that older apps, which skip a payload in a
newer schema whole, keep seeing every studyset nobody gave options.
Editing a studyset keeps its options, and Reset to defaults takes them
away.
The study queue takes each studyset's limits for its own cards and the
order of the studyset studied; a card's schedule now knows when it was
last reviewed, to count the reviews of the day. Sessions, the round's
end and the library's badges all count the same way, the badges now
with the person's own number of new cards a day too.

Settings offers English (UK), English (US) and Deutsch after the
device's language, each named in its own language. app_en.arb, the
template, is now British English (colour, centre) and the fallback for
any language the app doesn't speak; app_en_US.arb overrides the five
messages American English spells differently, and app_en_GB.arb is
empty, there so that Material's texts and dates are British too. The
German translation says "du" and keeps one set of terms throughout
(Lernset, Karteikarte, Lernpfad; Anki's own Stapel and Unterstapel in
the Anki import). arb_files_test checks that German has every message
of the template and that every translation keeps its placeholders.
resolveAppLocale picks the first language the device prefers that the
app speaks, in its country's variant where there is one; other English
is British, and a country alone never picks a language (Spanish in the
United States isn't American English), which Flutter's own resolution
would do.
Both MaterialApps take material_ui's GlobalMaterialLocalizations
delegates: gen-l10n's list brings flutter_localizations', which serve
only package:flutter/material.dart, so material_ui's widgets found no
Material texts in German and threw.
The editor's own text blocks show our placeholders while empty (list
item, to-do, quote, heading, and the desktop's / hint): the editor's
own follow a locale of their own, process-wide, in few languages. The
last texts written into widgets (the person's data failing to open,
the cards failing to read, the About dialog) moved into the arb files.

Settings gets a card for how this device shows the app: its appearance
(as the device, light or dark) and its language (the device's, or one
the app speaks, each named in its own language), side by side from
medium windows on, as two outlined dropdowns. Both stay on the device
rather than following the person: they are kept in
<app support>/device_settings.json (written to a temporary file and
renamed into place), read before the app shows, so its first frame
already looks as chosen, and a file that can't be read falls back to
what the device does. DeviceSettingsBloc sits above SessionGate's keyed
subtree, since the settings outlive every person, and both the plain
app and the person's app take their theme mode and locale from it.

tool/release.sh no longer takes a version: it works it out from the
commits since the last release, following semantic versioning (feat
raises the minor number, fix or perf the patch number, a breaking change
the major number from 1.0 on and the minor one before; other types
release nothing), or takes major, minor or patch as chosen. It shows the
version and its commits and asks first, checks that CI is green on the
newest commit with code, writes the version and a raised build number
into the pubspec in a signed release commit with a signed tag, and
pushes only once the APK and the snap passed their checks. The release
notes list the features and fixes. A run that stopped after its release
commit and tag carries on with them.

The editor scrolls a new selection into view by keeping a box around it,

that (180 px in the PDF reader, 200 in the composer), so once its content
could scroll, as with a screenshot taller than the field, the box stuck
out at both ends: the editor scrolled up and down for ever, drew no
frame again, and took ever more memory. RichContentEditor now keeps the
box at most half its own height (autoScrollEdgeOffset).

The README opens with what the app aims at: creating, sharing and
collaborating on study material, FSRS for retention, study material
organised with its external references, offline-first, and a transparent
stack anyone can host.
"Setting up" lists what developers need: Flutter as CI pins it, with
Flutter's own guide per platform; the Serverpod CLI; the Linux packages,
with what each plugin needs them for; Developer Mode on Windows, and why;
no Docker for development; Python for the scripts in tool/.
"Releases" says where releases are published, how to check a download
(the signed checksums, the APK certificate's fingerprint), how versions
are numbered, and how a maintainer makes one with tool/release.sh.
AGENTS.md: Windows needs Developer Mode for Flutter's plugin links too,
not only for pdfrx's build.

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.

tool/release.sh builds a release on the maintainer's laptop: one APK for
every phone, from a checkout of the signed tag and signed with the app's
own key, and the snap, both connecting to learn.halkyon.eu, the project's
instance; their checksums signed with GPG; the release on code.halkyon.app
through Forgejo's API, and the snap in the Store's edge channel.
Before building it checks that main is clean and pushed, that the tag is
signed by a key deploys accept, the version and a raised build number,
the pinned Flutter, and that the keystore holds the key whose certificate
tool/release/android-certificate.sha256 names. After building it checks
the APK's signer, package, version, that it isn't debuggable and that it
names the server, and the snap's version. The key's password and the
Forgejo token are asked for at each run and never stored.
Release builds take the app's key from the environment and otherwise fall
back to the debug key, so `flutter run --release` works anywhere. The
native libraries go into the APK compressed: an APK for three
architectures was 110 MB with them stored as they are, 48 MB now. The
list of dependencies Gradle adds for Google Play is left out.

Inserting a sound, a YouTube video or a study button through the / menu
in a card's field failed (found with the Snap build). Two causes:
A card field closes its editor when the focus leaves it, except to a
dialog. The / menu takes the focus too, so the editor was gone while
its menu was open, and the block chosen went to an editor that no
longer existed. The field now stays open while the editor's own popup
holds the focus (the editor package's keepEditorFocusNotifier, which
its editors heed for themselves, read through
RichContentEditor.popupHasFocus).
The editor package keeps the menu, and the layer closing it on a tap,
above everything until the chosen item's handler returns, so a block
asking in a dialog (formula, video, study button) had the menu over
that dialog. Our items now close the menu first; the handler is given
the menu for that.

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.

A Storage Box answers only inside Hetzner's network unless External
Reachability is on, for the box and for the sub-account. FTP and SFTP on
port 22 can't be turned off, so the sub-account turns off Samba and
WebDAV only. A host key of another type is checked against Hetzner's
list too.

learn.halkyon.eu dumps its database every hour (people's files are in it
too) and restic stores the dump encrypted in a Hetzner Storage Box,
keeping 24 hourly, 7 daily, 4 weekly and 3 monthly snapshots. The box's
own snapshots, removable only in Hetzner's Console, protect the backups
from a taken-over server. A systemd timer runs it as deploy; once a day
it also prunes and checks the repository. Failures go to the journal.
Hourly, because a restore costs people who started after the backup
what their device held: the app no longer finds its session and starts
anew. deploy/backups.md describes the setup, the restore and what a
restore loses; both were rehearsed on the local Compose stack.

The option's text sits in an IgnorePointer, so the read-only editor
drawing it doesn't take taps for selecting text. Tapping the text made
tap() warn that its centre doesn't hit it; the InkWell around it took
the tap anyway. Tap the option's InkWell instead.

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
the app's player on a device, which no widget test can: YouTube
refuses embeds that don't say where they are embedded.

An Anki import switches to Flashcards when the cards come into this
studyset (flattened or tagged by subdeck), not when subdecks become
sub-studysets; an imported path switches to Paths. Creating flashcards,
a note or a path switches to its tab as well, seen on coming back.
On opening, the studyset shows the first tab with content of its own:
unfinished paths, then flashcards, then notes; Flashcards when it holds
nothing. Its topics' content doesn't count, since the tabs list only the
studyset's own. A tab tapped or swiped to by the person, or material
added, stays.
Add material is built both in the app bar and in the bottom bar, so a
ContentTabCubit carries the requests to the tab controller, and
importFromAnki now returns the mode it imported with.
