feat(auth): Learn's and Todo's servers take password sign-in
Their migrations add halkyon_base's five tables for passwords,
authenticators, recovery codes, resets and sign-ins begun (nothing
else), and their pruning forgets sign-ins never finished and
authenticators never confirmed, hourly, and every GitHub ID once
GitHub sign-in has ended, daily.

feat(auth): say when an account signs in with its password
A code by mail no longer signs into an account with a password and an
authenticator; email sign-in now says so rather than failing unnamed.

feat(auth): a password with TOTP on the register, and resets
The register's side of signing in with an address, a password that never
leaves the device (SRP-6a) and a code from an authenticator (ADR 0017),
with members forwarding every step through AccountRegister:

- password.set: salt, Argon2id's costs, SRP's verifier, the public keys
  and the private keys wrapped twice, all made on the device; with the
  address a mailed code proves, an anonymous person becomes identified
  under their ID. It signs in once an authenticator is confirmed.
- passwordSignIn.begin and complete: SRP's two steps with a TOTP or
  recovery code. An address nobody has is answered from a decoy key as
  an account would be; every wrong credential is refused alike.
- authenticator: secrets sealed under totpKey (XChaCha20-Poly1305, bound
  to their row), each code accepted once, ten recovery codes with the
  first, the last one kept.
- accountRecovery: a lost authenticator reset 72 hours after the
  password and a mailed code or the recovery phrase ask, a lost password
  set anew with the phrase's signature, or the account reset with new
  keys 72 hours after a mailed code asks; a mail at each start, a
  sign-in calling it off.
- An account with a password no longer signs in by a mailed code or
  GitHub; no new GitHub account is linked where passwords are offered,
  and from GITHUB_SIGN_IN_ENDS GitHub signs nobody in and its IDs go.

Five tables, added by the module's migration; deletePerson deletes
their rows.

feat(keys): passwords taken as RFC 8265's OpaqueString
Other spaces become a plain space and the text is composed (NFC) before
Argon2id, so a password typed on another system, accents composed or
not, unlocks the same keys; empty passwords and control characters are
refused. The normalisation (unorm_dart) is pinned exactly, as it must
never change once an account exists. ADR 0017 records both decisions.

feat(crypto): recovery codes kept under the instance's key
A code holds 40 bits, which plain SHA-256 hashes in a leaked database
would give up to guessing; HMAC-SHA256 under a key of the instance kept
outside the database (recoveryCodeKey, at least 32 characters) gives
nothing to guess against without it. Decided 20 Oct 2026.

feat(keys): halkyon_keys, an account's keys on the device
ADR 0017's step 1, on libsodium (sodium 4.1.0+1, whose build hook
compiles the libsodium 1.0.22 it ships: a C compiler and make wherever
it builds):
- Argon2id (64 MiB, 3 passes, kept with the account and never below
  that) makes a master key, which libsodium's KDF splits into SRP's
  secret (x) and the key-encryption key.
- The account's X25519 and Ed25519 key pairs, their private halves
  wrapped with XChaCha20-Poly1305 under the KEK and under the recovery
  key, bound to their public keys.
- A 24-word BIP-39 recovery phrase (the English list, MIT) and the
  recovery key derived from it.
- Data keys sealed to the account with crypto_box_seal, bound to their
  IDs; content in ADR 0002's envelope, encrypted with a data key and
  signed with Ed25519 (detached), bound to a context the caller names.
- Secrets in libsodium's guarded memory where its API takes them.
- Tests: libsodium's Argon2id known answers, BIP-39's English vectors,
  round trips and every refusal.

feat(crypto): TOTP and recovery codes
ADR 0017's second factor, in halkyon_base_server (base.dart):
- RFC 6238 with HMAC-SHA1, 6 digits, 30-second steps, one step either
  way. checkTotp takes the account's last accepted step as a required
  argument and refuses a code of that step or before, so no code is
  accepted twice; every step of the window is computed and compared.
- 160-bit secrets in RFC 4648 Base32 (strict decoding); the otpauth
  URI with issuer and account escaped.
- Ten recovery codes of eight Crockford characters (short_code.dart),
  kept as SHA-256 hashes, each used once, every hash compared in
  constant time.
- Tests: RFC 6238 Appendix B (8 digits, SHA-1, SHA-256, SHA-512), the
  window, replay, RFC 4648's Base32 vectors, the recovery codes.

feat(crypto): SRP-6a, the register's half and the device's
ADR 0017's step 1. Generic over group and hash (SrpGroup); production
takes RFC 5054's 3072-bit group with SHA-256. k = H(N | PAD(g)),
u = H(PAD(A) | PAD(B)), K = H(PAD(S)),
M1 = H(H(N) xor H(g) | H(I) | s | PAD(A) | PAD(B) | K),
M2 = H(PAD(A) | M1 | K). A and B must lie in 1..N-1 and u must not be
0; a and b are 256 bits from Random.secure(); proofs are compared in
constant time. x comes from the caller (halkyon_keys makes it); RFC
5054's own x is there for the vectors only.

- The register's half in halkyon_base_server (base.dart: srpChallenge,
  srpVerify), the device's written by hand in halkyon_base_client
  (srp.dart: SrpClient, srpVerifier). Serverpod's generator cleans and
  writes only a client's lib/src/protocol/ (serverpod_cli 4.0.4's
  _getDirectoriesRequiringCleaning; a generate leaves srp/ untouched).
- Tests: RFC 5054 Appendix B on both halves; the client against the
  register, succeeding and every refusal.
- The module's tests depend on its client, and pub resolves every
  member's dev dependencies, so Learn's server image takes the module's
  client into its workspace too.
- The format check covers the hand-written half.

refactor(halkyon_app): the account section, About, the language and countries' names, shared
What Learn and Todo each held now comes from halkyon_app:
- AccountTiles: whose account on which instance, switching, signing
  out (asking first for an anonymous account, as it deletes it) and
  deleting it (asking first), the app's own words passed in.
- showAppAbout: the app's name, version, icon and legalese as it gives
  them, the source of what the instance runs (AppDependencies gains
  sourceCodeUrl), the app's own parts, the licence list.
- resolveAppLocale: the first preferred language the app speaks, never
  by country alone, British English otherwise.
- AssetCountryNames, the default of InstanceGate and InstanceScope:
  Unicode CLDR 48.2's territory names in English and German
  (tool/country_names.py, 7.6 KB), Hong Kong, Macao, Myanmar and
  Palestine by their short names as Learn's world map has them, so
  Todo says "Germany (EU)" where it said "DE (EU)".

Learn's texts read as before in every language; its About bloc and
gateway, its country names from the world map and the keys only the
moved code used are gone, as are Todo's copies.

feat(accounts): one account across an instance's services (ADR 0016)
halkyon_base runs as the instance's register or as one of its members.
The register keeps the ways in, handles and profiles; members ask it
over HTTP with the instance's shared secret (instanceSecret), and open
sessions of their own for its accounts, under the same account ID.

- AccountsMode from the environment: INSTANCE_MEMBERS on the register,
  ACCOUNT_REGISTER_URL on a member. Learn always holds the register
  (Explore joins the profiles); Todo is a member where it is set.
- AccountRegister: LocalRegister, RemoteRegister, an in-memory one in
  tests. Calls between services on the web server, refused without the
  secret (constant-time compare); a server needing it doesn't start
  without it.
- Deleting an account deletes it everywhere: notices per member kept in
  the deletion's transaction (account_deletion_notice), told at once and
  hourly until confirmed; members prune daily whom the register no longer
  knows, never while it knows none of them or can't be reached.
- Deploy: INSTANCE_SECRET and INSTANCE_MEMBERS in compose and .env.

refactor(profile): handles and profiles move into halkyon_base
People's public profiles are the instance's register's (ADR 0016), so
the module now holds them: the public_profile table (unchanged, so
Learn's migration records versions only; devices get the table empty,
as they hold every module's tables), the profile and profiles
endpoints under `base`, the handle rules, the link checks and the page
at /@handle, whose foot names the app as the host's configuration says
(profilePageNote). Deleting a person deletes their profile in the
module's core.

Hosts read profiles through the module (profileOf, profilesOf,
personWithHandle, fixHandle; saveProfile for their tests), behind an
AccountRegister that is this server's own database for now. Learn's
feedback, discussions and publishing ask it; publishing fixes the
handle just before it writes the release, outside its transaction.
Explore still joins the table in its search, so Learn holds the
register wherever it runs. Learn's app calls the module's endpoints;
a profile not found is ProfileNotFoundException. Todo's database gets
the table too (it was never deployed).

feat(todo): the app on halkyon_app, with its own icon
Todo's app is halkyon_app's instance and session gates with Todo's
frame ("Todo" under "Halkyon", its icon, its own sentences) and an
instance check accepting only `todo`; TodoDependencies on an instance,
an empty TodoPerson per person, nothing kept or synced yet. A person
sees an empty home and their account: whose it is on which instance,
switching account, signing out and deleting it (each asking first where
it deletes), and About with the source of what the instance runs and
the licence list. Texts in British English and German. App ID
app.halkyon.todo on every platform, GitHub's callback scheme registered
on Android, no web build.

Its icon is Lucide's list-checks (lucide-static 1.50.0) in the brand's
blues on white: tool/app_icons.py draws its strokes with Pillow and
writes every platform's launcher icon; Lucide's ISC notice joins the
licence list.

session logs are never persisted. Todo was never deployed, so its
migrations start again with one initial migration. The root's lints

build(release): a Dart release tool for every app
tool/release.dart releases one app: `dart run tool/release.dart learn
[major | minor | patch] [--dry-run]`, each app configured in Dart beside
it (apps/learn/release.dart). Every step and check of tool/release.sh
is kept: the repository as pushed, resuming after a release commit and
tag, Flutter as CI pins it, the tools, the key and its certificate pin,
secrets asked for without echo and never written down, CI green on the
newest commit, the signed release commit and tag by a key deploys
accept, the APK built from a checkout of the tag and checked, the snap,
the signed checksums, pushing only after both builds passed, the
release on Forgejo, the F-Droid repository, the Snap Store once a
channel is set.

New: tags per app (learn-v0.19.0, Learn's v… counting as its
history); only commits touching the app decide its version (its folder,
the shared packages it uses by path, the root pubspec and lock, its
release files, where its packages were before the move); --dry-run
reads all of it, lists every step and the notes, and what a release
would refuse, changing nothing. The pure parts are tested in
test/release/. Learn releases build 21 with tool/release.sh, then
switches.

- Melos 8.9 as the root's dev dependency, with scripts across the

  its logger, unchanged in 0.5.

  through Melos (--changed-since=<commit> for only what changed and what

  need (tool/workspace_only.sh); compose, the deploy's migration test,
  the snap, the release script, the editor's launch files and Learn's
  asset tools (run from apps/learn) follow the new layout.
- The project's source is named as project-halkyon/halkyon (source link,

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

Deploy this only together with the release of build 21.

halkyon_app: instances, sign-in and sync plumbing for Halkyon's apps
What every Halkyon app's shell needs, taken from Halkyon Learn's and set
on halkyon_base's client: the instances a device keeps an account on,
the first start's tiles and where an instance keeps people's data, the
account switcher; signing in anonymously, with GitHub or an email code,
switching person and the start screen; the gates that build an app's
dependencies per instance and per person; and the sync service with its
status, Settings card and banner. Texts of its own in English and
German take the app's name; what only the app can say, it passes in.
Fakes for apps' tests are in testing.dart.

An instance's basics now name the app it serves (`app`, set by the
host's configuration), and an app accepts only an instance of its own.
SerialQueue and CoalescingRunner move into halkyon_core.

halkyon_base: a Serverpod module for sign-in, accounts and instance basics
What every Halkyon server has, taken from Halkyon Learn's: anonymous,
GitHub and email-code sign-in with their endpoints, an account's ways
in and its deletion, the pruning of abandoned anonymous people, of
sign-up attempts and of expired codes, and the instance's basics (the
sign-in ways offered, the source link, the minimum app build, where
people's data and its backups are). Endpoints sit under the nickname
`base`. A host configures it in one place before its pod starts: its
name for the mails, its source link, its minimum build, and hooks that
delete its own data with a person.

The tables keep Learn's names, columns and indexes, so a host moving
onto the module migrates nothing but version rows. Server package under
the SSPL, client under the AGPL, as Learn's are.

The theme, Noto Sans, the window sizes and the widgets every screen is

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
and icon. Nothing on screen changes.

Halkyon's shared packages
A pub workspace of the Dart packages Halkyon's apps share: halkyon_ui,
Halkyon's look (the theme, fonts, layout and shared widgets, with texts
in English and German), halkyon_core's low-level primitives and
halkyon_interop's cross-app contracts. Dart 3.13 with LeanCode's lints,
configured once at the root; apps take a package by git, pinned to a
signed commit.

Its operator sets DATA_LOCATION and BACKUP_LOCATION in deploy/.env (a

where the disks are, never which law governs. The flags come from the
flag package, which draws flag-icons; its MIT notice joins the licence

feat(instance): the first start offers instances as tiles
Under the wordmark on a cobalt wash, two tiles as Proton's account page
shows its services: the build's instance, chosen in one tap, and
another, which unfolds the address to type. A ring from cobalt to
copper, a glow and a tagline come in under the pointer, on the

always show. The launch screen's "Halkyon" over "Learn" becomes
BrandWordmark, which both show.

docs(store): say studysets are the learners' own and instances anyone's
All checks were successful
CI / check (push) Successful in 20m48s
CI / deploy (push) Has been skipped
The Snap Store and F-Droid listings now say what the demo video says:
every studyset is made by its learners (build one for any subject, or
copy one someone published), the app connects to any instance, the
repository holds everything to run one, and all the code is public
(app AGPL-3.0, server SSPL-1.0). Signing in later keeps everything with
GitHub or an email address, now that both are ways in.

The F-Droid listing takes the snap's description again, as its header
says; it had kept the text from before v0.17.0. AGENTS.md no longer
says it declares TetheredNet, which it dropped once the app could
choose its instance.

perf(sync): the fork's signed commit with fast merged deletes and batched inserts
The offline sync package's shared part now comes from the fork's branch
halkyon/batch-inserts (949a664, signed), adding two changes to the pin.
A merge only deleting rows skips the projection pass when every visible
row below them goes with them (a card deleted on one device, in a
library of 8,000 cards: 5.4 s for the server to merge, now about 35 ms;
4 s on each other device, now about 0.1 s). And a merge the pass leaves
out writes its new rows up to 1,000 to a statement, its proof also
taking nested studysets (a first push of that library: 35 to 41 s on
the server, now about 5; a device receiving it, 60 s, now 44).

A new sync test deletes a card on one device while another rates it:
the merged delete declines the shortcut there, and both devices end
without the card or its rating.

After a merge or a switch of branch the workspace's resolution could

CI / check (push) Successful in 20m15s
CI / deploy (push) Has been skipped
Pushing from a worktree failed before any test ran: "Because
halkyon_learn_flutter requires the Flutter SDK, version solving
failed." Git hands a hook in a worktree an absolute GIT_DIR, which
overrides the -C that pub runs git with on its git dependencies, so pub
judged the workspace's resolution stale and resolved it with dart alone.
The checks now clear git's variables first; git finds the repository
from the folder it runs in.

test(sync): test devices sync through their sync service
A test device synced by calling the engine itself, so its repositories
never heard of what a sync merged; reading the database each time, they
didn't need to. Since cards and reviews are kept until something changes
them, a device went on reading its cards from before the sync, and the
conflict test failed. Devices now sync through their SyncService, as the
app does, and fail when the sync failed. SYNC_TEST_SERVER_DIR names the
server folder whose database the SQL checks read, for a worktree testing
against another checkout's running server. All 30 sync tests pass.

one has is kept beside the pending count in sync_pending.json (a file
from before counts as synced), read as the person's data opens, and
carried in SyncStatus.syncedHere.

refactor: one runner for work asked again while it runs, shared editor parts
CoalescingRunner (core/async/) runs work one run at a time and once more
after a run during which it was asked again; watchReads reads a
repository's value so for each listener. They replace nine copies of that
loop: the card, note, path and PDF watches (notes, paths and PDFs read
once per change before, now a burst reads once more), the progress
repository, the material and exam cubits, file uploads, and the sync
service's syncs and pending count. Each now goes on after a failed run
when another was asked for, which some dropped. The card browser keeps
its own loop, as it emits inside the handler that started it.

The card, note and step editors show conflicts through one
ConflictVersions widget, and the note and step editors their saving
through one EditorSaveStatus and SaveStatusLabel.

TagContent, ExamProgress with examCardsToStudy, and PdfChapter move into
their features' models, so widgets no longer import a payload codec, a
service or the PDF engine for a type, and an archive's title is read in
its importer rather than its cubit running the payload codec.

perf(dictionary): a search finds keys by their first characters, indexed
A search matched LIKE '%|eat%' over every entry's barred keys, which no
index can answer, so each one read the whole dictionary: 43-57 ms in
JMdict's 218,863 entries. dictionary_search_key holds a row per key and
loose key with its first one, two and three characters in columns of
their own and one index on them, so the keys a query starts are an
equality the index answers whatever the database's collation (Serverpod's
models can't declare COLLATE "C" or text_pattern_ops). A search now takes
5-26 ms, at 1.4 million rows and 190 MB for JMdict, and its load takes
72 s instead of 33 s.

The loader fills the table beside the entries and loads a dictionary
again when it has none. Until then, in the minutes after the deploying
server starts, the search reads the barred keys as before; those columns
stay until a later release, since the server before a deploy's switch
still searches them. The migration only creates the table and its index.

perf: a path's steps, untagging and the card browser in bulk; fix untagging
A path's steps are now made in one batch, as one change
(LearningPathRepository.createSteps), for the path import and the release
copier: each step's change had everything following the paths read again.
On a real library, 60 steps took 3 s, now 0.4 s. An import's progress
moves per path with its steps.

The card browser takes tags off the chosen cards at once
(TagRepository.removeTags) instead of reading every card's tags three
times a card. It keeps each card's search text and A-Z key while the
card's heads and tags are the same, builds no search text without a
search, and works out each A-Z key once instead of at every comparison
(8,067 cards: 250,870 keys and 426 ms, now 8,067 and 94 ms).

Fix: SyncTagGateway's deletes passed a set literal to the id column's
inSet, which Serverpod refuses at run time, as the column is nullable as
declared. Taking a tag off a card, note or path has failed on devices
since v0.1.0; the fakes never met it. The sync test now takes tags off.

perf: what everyone follows is read once, and two server hot spots
Studysets, settings, tags and every studyset's progress are now a
LatestValue (core/async/): a screen starting to follow gets the value last
read, and only the first has it read. Before, every screen opening had the
whole table read again and handed to every screen open. While nobody
follows, nothing is kept or read, so the tags are no longer read after
every card change with no tag screen open. StudysetRepository serialises
its reads with SerialQueue instead of a kept future chain.

The card browser, path runner and path list blocs no longer add events
from stream callbacks once closing, which the later arrival of the tags
made one test hit.

Server: publishing gathers each item's tag names in one pass instead of
scanning every assignment per item, and deleting a person deletes their
stored files without reading their bytes back.

On a copy of a real library (8,067 cards, 20,907 reviews, 20
studysets), every open list read every card (0.8 s), every review
(0.25 s) and replayed schedules after every change, each on its own:
the library, every studyset open on the stack and its topics.

- CardRepository keeps each studyset's cards and every card's stamp
  until a card changes; a read begun before a change keeps nothing.
- ReviewRepository keeps the whole log once many cards' reviews are
  asked for, updated by this device's writes and read anew after a
  sync brings others'.
- StudysetProgressRepository works out every studyset's progress once
  for every list and hands the last to whoever follows it next;
  StudysetListBloc reads it.

A full recount now takes about 65 ms. Home no longer rereads every
revision after each rating.
