ci: a commit that passed the checks isn't checked again
All checks were successful
CI / check (push) Successful in 5s
CI / deploy (push) Has been skipped
v0.1.0
A fast-forward merge brings the commit a branch's push checked to main
unchanged, and CI ran every check a second time before deploying it. The
check job now marks every commit that passed in the runner's home
(checked/, kept 90 days), and a commit marked already skips straight to
its deploy; the sandbox check still runs every time. Only pushes run CI,
so only those who may push can leave a mark.

fix: the release script checks its token on the repository
All checks were successful
CI / check (push) Successful in 9m36s
CI / deploy (push) Successful in 15s
It asked Forgejo for the token's user, which needs the scope read:user;
the token the script asks for only has write:repository, so the check
would have refused a token that works. It now reads the repository
itself, which that scope covers.

feat: releases work out their version from the commits
All checks were successful
CI / check (push) Successful in 9m17s
CI / deploy (push) Successful in 14s
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.

Channels for now: the release on code.halkyon.app (APK, snap, checksums)
and the F-Droid repository; the Snap Store upload is off until
snap_store_channel names a channel.

The repository is Halkyon's, for all of its apps, so its address is the

Learn's own address, for its website later. Moved before anyone but the
maintainer had added it; the address is permanent once people have.

feat: an F-Droid repository at learn.halkyon.app
All checks were successful
CI / check (push) Successful in 9m16s
CI / deploy (push) Has been skipped
Releases also publish the APK in the project's own F-Droid repository,
https://learn.halkyon.app/fdroid/repo. tool/fdroid_repo.sh adds the APK,
signs the indexes with the repository's own key and uploads them to
ramiel as the user fdroid, whose key can only write into the folder
Caddy serves (rrsync), the APKs first and the indexes last.
tool/release.sh checks that key and its password before building and
publishes after the Forgejo release.

- tool/release/fdroid/ holds the repository's settings (Halkyon, the
  snap's icon) and the app's listing (the snap's text), with the
  anti-features TetheredNet (learn.halkyon.eu only, for now) and
  NonFreeNet (YouTube, the server's SSPL) declared with their reasons,
  in F-Droid's own definitions and with its icons (fdroiddata, AGPL v3).
- The index key's certificate is pinned: a new key would make the F-Droid
  app refuse the repository.
- fdroidserver v2.4.5, since Ubuntu's v2.2.1 knows neither TetheredNet
  nor reasons.

README and AGENTS.md describe it.

fix(app): a click in a short editor no longer freezes the app
All checks were successful
CI / check (push) Successful in 9m39s
CI / deploy (push) Successful in 14s
The editor scrolls a new selection into view by keeping a box around it,
220 px by default, inside its viewport. A card's field is shorter than
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).

Found clicking a screenshot in a card in the PDF reader, on Linux.

docs: the README's aims, developer setup and releases
All checks were successful
CI / check (push) Successful in 10m0s
CI / deploy (push) Successful in 11s
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.

feat: the Linux app as a Snap
All checks were successful
CI / check (push) Successful in 9m31s
CI / deploy (push) Successful in 11s
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.

feat: a release script for the APK and the snap
All checks were successful
CI / check (push) Successful in 9m8s
CI / deploy (push) Successful in 1m5s
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.

fix(app): blocks from the / menu go into card fields
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.

feat: the app tells when sync fails, and when it is too old
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.

Reachability is on, for the box and for the sub-account. FTP and SFTP on

feat(deploy): hourly off-site backups with restic
All checks were successful
CI / check (push) Successful in 9m0s
CI / deploy (push) Successful in 7s
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.

feat: PDF sources: read, take notes and cards from pages, deadlines
Some checks failed
CI / check (push) Failing after 26s
CI / deploy (push) Has been skipped
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.

feat(app): editor blocks: callout, spoiler, formulas, files, video, study button
All checks were successful
CI / check (push) Successful in 8m34s
CI / deploy (push) Successful in 1m1s
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

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.

feat(app): learning paths in the studyset screen: worked through and written
- A Paths tab before Flashcards and Notes: each path with its title and
  secondary title, dimmed once completed; Edit, Reset progress (with an
  undo) and Delete (with an undo) behind its options. The studyset opens
  on its paths while one is unfinished, on its flashcards otherwise.
- "Create a path" in Add material asks for the titles in a sheet and
  opens the new path to write; "Import a path (JSON)" reads a file in
  the import format, says what came in and how many blocks were left out
  (images and animations: the app never fetches from the web).
- The player: one step at a time at reading width, a bar of the steps
  above, Back and "Check answers" / "Continue" / "Finish" below. It
  opens at the first unfinished step; an exercise passes only once
  answered right, as often as it takes; after a check, only the
  learner's own picks are marked, with the author's feedback; sources
  behind a chip; a finish screen leading to the next path. Words and
  items are dragged into place, or tapped into place for phones.
- Writing: the path's screen (titles, description, tags, steps added by
  kind, reordered, deleted with an undo) and the step's (title, text
  with the format bar, its kind's exercise, feedback for right and
  wrong in the whole window, sources). The step saves on what it
  started from, as notes do, read-only while devices disagree until a
  version is kept.
- The library and the topics count paths; steps done count on the
  dashboard, for the streak and the activity.
- The rich-text screen for a studyset's description moves to core, for
  the steps' feedback too, and gains the format bar.

feat: learning paths in studysets, synced, with progress and tags
Server: five synced tables, only additions (migration
20261002211346701-learning-paths):
- `learning_path`: its studyset, a fractional position, and its own
  content in the payload {title, secondaryTitle, description}, the last
  writer winning, as a studyset's;
- `learning_path_step`: its path, a position, and its kind ('info',
  'singleChoice', 'multipleChoice', 'dragAndDrop', 'fillInTheBlank'),
  fixed once created;
- `learning_path_step_revision`: a step's content as append-only
  revisions, as a card's: {title, body, exercise, rightFeedback,
  wrongFeedback, sources};
- `learning_path_answer`: an append-only log (right, wrong, continued,
  reset), as reviews are, so answers from two devices never conflict;
- `learning_path_tag`: one row per assignment, as `card_tag`.

App, `feature/learning_path`: the five exercises and their JSON, grading
that marks only the learner's own wrong picks, progress worked out from
the log (a step is done once answered right since its last fresh start),
`LearningPathRepository` (steps saved on what they started from, merged
per field) and `PathProgressRepository` (answers, resets with Undo, the
times steps were done). Paths share the person's tags; deleting a path
or a step can be undone for a moment, and a studyset's deletion takes
its paths. Tests: models, codecs, repositories, tags, the device
migration guard, and sync tests against the server (four).

The sync engine (serverpod_offline_sync v0.0.8) keeps rebuilding the
projections of every space on every session of a server whose first

(serverpod_offline_sync#150, open). `serverpod start` migrates in the

ci: install exactly the committed lockfile, and try twice for pub's git bug
All checks were successful
CI / check (push) Successful in 7m8s
CI / deploy (push) Successful in 1m1s
`flutter pub get --enforce-lockfile` installs what pubspec.lock says or
fails with pub's own message, so CI never resolves something else on
its own.

The second try works around https://github.com/dart-lang/pub/issues/4912
(Dart v3.13): when the runner's cached copy of a git dependency's
repository lacks the locked commit, pub resolves that package without
its dependencies. That failed the CI run of 079179d with Flutter's
"package_graph.json: dependencies for `universal_platform` missing".
With --enforce-lockfile the first run fails at pub instead, having
fetched the commit, and the second goes through; checked locally on a
copy of the pub cache with the editor fork's commit removed. pub's fix
(ebba0dc) is in no Dart release yet.

feat(app): notes in the studyset screen, written in the whole window
- A Notes tab beside Flashcards lists a studyset's notes in order: the
  title ("Untitled note" without one) and when each was last edited
  ("Edited 5 minutes ago", by the calendar from yesterday on, the date
  after a week); Edit and Delete behind its options. Deleting asks,
  then offers Undo for a moment (`NoteDeletions`). With none, the tab
  says so.
- "Create a note" in Add material opens a new note over the tabs; so
  does a note of the list. The note: a title, its tags once it exists,
  and its text at reading width; the app bar says how saving stands.
- `NoteEditorBloc` saves after 5 seconds without typing, when the app
  goes to the background, and when the note is closed (the bloc saves
  as it closes, so leaving never waits, and the write outlives the
  screen). Each save builds on the revisions the editor started from;
  another device's change takes over a note with nothing unsaved, and
  merges with one that has. A note changed differently on two devices
  is read-only until the person keeps a version of each field in
  conflict. A new note is created by its first save, never when left
  blank; a note deleted elsewhere says it no longer exists.
- The editor gains a format bar, docked below it while it has the
  focus (`RichContentEditor(formatBar: true)`): alignment, bold,
  italic, underline, superscript and subscript. It takes no focus, so
  the selection stays. Superscript and subscript are inline marks of

feat: notes in studysets, synced and merged as cards are, with tags
Server: three synced tables, only additions (migration
20261002191122122-notes): `note` (its studyset, a fractional position),
`note_revision` (append-only, as a card's: parents, author, report,
the payload {schemaVersion, title, body}) and `note_tag` (one row per
assignment, never updated, as `card_tag`). Each indexes `spaceId`, and
everything goes with its space, studyset, note or tag. A migration of
synced tables locks app builds from before it out of syncing (ADR 0002,
rule 3): cheap now, before the first release.

App, `feature/note`:
- `NoteContent` is a title and rich text, merged apart (ADR 0003): a
  title changed on one device and the body on another both survive, a
  body changed on two is a conflict.
- `NoteRepository` creates a note at the end of its studyset, saves an
  edit on the revisions it started from (`saveEdit`, as the card
  composer now does), says when a note was last edited (its newest
  head's UUID v7), counts notes per studyset, and deletes a note's
  revisions blanked first (ADR 0002, rule 2).
- Notes share the person's tags: `setTagsOfNote`, and folding tags of
  one name or undoing a tag's deletion covers notes too.
- The delayed deletion with its Undo moves to `core/async`
  (`DelayedDeletions`): `StudysetDeletions` builds on it and now takes
  a studyset's notes too; `NoteDeletions` deletes a single note.

Tests: content, merge, payload, repository, deletions, tags, the device
migration guard, and sync tests against the server (four).

fix(app): a card's edit builds on what it started from
The composer saved a stored card with the card's current heads as its
parents, so whatever had arrived meanwhile was replaced, not merged:

- another device's change to the side the person left alone was
  overwritten silently;
- an edit made while saving, saved before the card was read back,
  stood beside the first save: a conflict with itself;
- a new card left again before it was read back wasn't written at
  all, while it showed as saved.

A draft now keeps the revisions its content came from (`base`): taken
with the stored content while the person hasn't changed it, and its own
revision after each save. A save replaces exactly those
(`CardRepository.saveEdit`), so what another device wrote meanwhile
stays a head of its own and merges per side (ADR 0003): a side only it
changed comes through, a side both changed is a conflict to settle. A
changed draft takes new conflicts only once it is saved.

Fix what the first Android run found
All checks were successful
CI / check (push) Successful in 6m44s
CI / deploy (push) Successful in 59s
The flow ran on a Pixel 9a and its emulator (2026-10-02); what it found:

- The composer stayed on the card just written after "New flashcard", and
  on the original after "Duplicate": leaving a card changed the state
  before the new one was in it, so the screen took the new card for gone.
  It now waits for the card it asked for.
- Bottom sheets reached under the status bar with the keyboard open
  (useSafeArea).
- The field being written stayed behind the keyboard: the editor scrolls
  only within itself, so the card face now keeps it in view when it opens
  and when the keyboard rises, as a text field does.
- A tap on read-only rich text put a caret in it and opened the keyboard on
  phones, and in the composer never opened the field. RichContentView is
  display only now: no selection, taps go to what surrounds it, a sound's
  button still plays (decided 2026-10-02).
- The card types broke their names on a phone; they are choice chips that
  wrap (decided 2026-10-02).
- The week overview marked days before the person's first activity as
  missed; they show nothing now. An import starts the activity too, without
  counting as studying (decided 2026-10-02).
- A composer preview cut short gave no sign of it; it fades out over its
  last 32 dp, only when cut short (decided 2026-10-02).
- "Isn't on this device yet" showed for any image or sound that failed;
  a file that is here but can't be decoded now says so, and offers no retry.
- The signed-in account card was narrower than the anonymous one.
- The composer's title said "Create flashcards" also when opened on a
  stored card; it says "Edit flashcards in …" then (decided 2026-10-02).
- The Anki fixtures carry a valid PNG and a silent MP3, so they also serve
  to try the import by hand (decided 2026-10-02); regenerated with Anki
  26.9.3.

Limit how much room people's files take

An anonymous person may keep 100 MB of images and sounds, an identified one
500 MB, and one person more by a file_allowance row the operator adds; all
of them together 15 GB, since every file is in the database and in each dump
the server keeps (decided 2026-10-02). Each comes from the environment
(FILE_LIMIT_*_MB), with these defaults, documented in deploy/.env.example.

The server checks when an upload starts, counting unfinished uploads so they
can't fill the disk unnoticed, and again when it finishes, counting what is
kept, so uploads started side by side can't overshoot; a refusal is a
FileLimitExceededException, and an upload refused as it finishes is deleted.
deletePerson deletes the allowance with the person. Migration: the new
table file_allowance, only added.

The app keeps a refused file waiting on the device and stops that round of
uploads; the Anki import warns when a deck's files may not fit in the room
left (asset.usage()).

Import Anki decks with their files and history
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).

Store people's files on the server
The asset endpoint (login required) takes a file into the caller's own space
by its SHA-256 and serves an asset row's file only to its space's owner and
members; anyone else, and a deleted row, gets NotFoundException as for a
missing file. startUpload hands out Serverpod's upload description, or null
when the file is there already (claiming it anew); finishUpload keeps the
upload only if its content has the announced hash. Files are stored in the
private database storage at spaces/<space>/<sha256>, at most 20 MB.

deletePerson deletes the person's files in its transaction, and a daily
future call deletes the files no live asset row refers to, and uploads never
finished, 7 days after they were last claimed (ADR 0004, rule 5).

The tests run on the sync engine's database, as the server does, without
rollback: its writes take transactions of their own.

schedule. Each type studies its way: a word shows its reading and
meanings, a multiple-choice card is picked and checked, a matching card
sorted by dragging or tapping and checked; then the person rates (Bad,
OK, Good, Perfect, each with when the card comes back). Progress shows
as pills, or a tally bar while cramming; a round ends with how it went.
