OidcBrowser opens the page of an attempt the server began (OidcStart),
waits until the browser comes back by an OidcReturn (the app's scheme,
a verified https address, or the loopback) and returns the provider's
code (OidcCode), its refusal (OidcDenied), or nothing when the person
closed the browser. It checks the returned state against the attempt's,
as the server never compares it; a wrong state, neither one code nor
one refusal, no browser or a failed way back are OidcCallbackExceptions.
halkyon_app's LoopbackWebAuth moves in with its tests, relicensed from
AGPL v3 to BSD-3-Clause by its author, the developer; GitHub's sign-in
keeps using it from there until it ends. The package is BSD-3-Clause,
publish_to: none, as the module (ADR 0023, D2, D3).

halkyon_oidc_server and its generated client halkyon_oidc_client: any
provider following OpenID Connect's code flow, beside Serverpod's own
providers, with a preset for SimpleLogin (no PKCE, no `typ`). Nothing
of Halkyon's is in it; BSD-3-Clause, `publish_to: none` for now.
- Attempts in `halkyon_oidc_attempt` (ADR 0020's D13): the ID
PostgreSQL's gen_random_uuid(), a state and a nonce of 32 random
bytes, PKCE's verifier where used, the caller if signed in; ten
minutes, taken once. A host may begin the state with a marker.
- The code exchanged by the module itself, so a provider out of reach
(a timeout, a 5xx) is told apart from a refused code; the ID token
checked with dart_jsonwebtoken's algorithms (ADR 0020's D12): the
provider's algorithms alone, the key its `kid` names, of the right
type; issuer, audience and `azp`, expiry, time issued, `nbf`, a
minute's leeway; the attempt's nonce; a `sub`.
- Keys kept an hour, fetched again for an unknown `kid` at most once
a minute; discovery checked against the issuer; every request with
a timeout.
- Identities in `halkyon_oidc_identity`: the provider's key and the
`sub`, one per person and provider, deleted with the person.
- The stock endpoint (`OidcIdpBaseEndpoint`), and the parts for a host
with rules of its own: begin, verify, keep and takeKept, link,
accountOf, unlink; merging people; a limit per network.
- The forwarding page, moved here from halkyon_base in the next commit.
The package's main library is the code generator's, as halkyon_base's;
a host imports `package:halkyon_oidc_server/oidc.dart`. ADR 0023's
point 5 no longer names OAuth2PkceUtil, which the module doesn't use.

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.

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
workspace (analyze, test:dart, test:flutter, generate, check) and its
filters (--diff, --include-dependents); cli_util overridden to 0.5.2
for it, since Learn's flutter_launcher_icons asks for 0.4 and uses only
its logger, unchanged in 0.5.
- tool/check.dart in place of tool/check.sh: packages, formatting of our
own files, analysis, the tools' tests, then every package's tests
through Melos (--changed-since=<commit> for only what changed and what
depends on it). tool/pre-push is the hook: the signature check, then
the checks. CI generates every server's code and runs the same check.
- The images build from the root with a workspace narrowed to what they
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,
snap, F-Droid listing, release uploads); the AGPL packages carry the
licence's own text.

The root pubspec lists Learn's, Todo's and the shared packages, which
the apps now take by path instead of pinned commits of halkyon_shared:
one resolution, one lockfile. Learn's versions stay as they were; Todo
moves to Serverpod 4.0.4 and Dart 3.13 with the rest (its generated code
unchanged), drops google_fonts, which it never used, and a template
line Dart 3.13 refuses.

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.

halkyon/fast-merges (f062725, signed), adding two changes to the pin: a
merge only inserting new rows proven unable to change the projection
skips its passes (a rating another device made, received in a library of

after the synced tables changed rather than on every session and merge
(upstream #150). AGENTS.md's note on #150 stays until a deploy runs it.

The offline sync package's shared part now comes from the fork's branch
halkyon/fast-deletes (b545035, signed), which stacks two changes on the
byte payload fix: onInboundMerge, called only when changes from the
remote peer were merged, which the app now reads again on rather than
after every save's sync; and local deletes that skip the foreign key
projection pass when it can't change it (8 s for one delete in a library
of 8,000 cards, 30 s for a card, now tens of milliseconds).

serverpod_offline_sync v0.0.10 compares byte payloads byte by byte, each
byte through a UUID parse that throws and is caught: 36 ms for two 2 KB
payloads. A sync whose projection loaded a few thousand card revisions
kept the server's isolate busy for minutes, answering no one, while the
client's method stream idled out after 40 s and sent everything again,
without end.
The shared package now comes from our fork (project-halkyon/
serverpod-offline-sync, branch halkyon/byte-payloads at a signed commit):
v0.0.10 with that comparison fixed, 25 µs for the same payloads. The
override sits in the root pubspec, which the server's Docker build keeps,
so production gets it too. The fix is offered upstream; drop the override
once a release has it.

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.

A package of its own in the workspace, without Serverpod (AGPL, like the
tooling): an adapter per source writes one format for all, documented in
its README, which the server will load. The format is JSON Lines: a
header (source, version, languages, licence, credits), then entries with
a headword and reading, labels (`common`, `jlpt:n5`), a rank, the keys a
search matches, and the entry as cards take it. Everything specific to a
language happens in its adapter (Japanese: forms, readings in kana and
Hepburn romaji, long vowels typed once, meanings without "to" and
articles), so the server's search knows no language.
JMdict comes as jmdict-simplified's JSON, read one entry at a time: all
218,863 entries in some 20 seconds and 300 MB, 16.8 MB gzipped. The JLPT
lists (yomitan-jlpt-vocab, CC BY-SA 4.0, from Waller's CC BY lists) add
levels by JMdict entry, the easiest when a word is on several, and give
the headword its common spelling. Words rank N5 to N1, then the other
common words, then the rest.
The server's image leaves the package out, as it does the client's.

Moves every Serverpod package, and the four overrides for serverpod_offline_sync, from v4.0.2 to v4.0.3 before the first synced table's migration exists, so that migration is created on the version that stays.
v4.0.3 contains fixes only. Checked before moving: serverpod_database gained only backwards-compatible changes, none of which the sync package calls into. Server-side session keys are hashed as before (the cheaper argon2 applies to JWT refresh tokens, which we don't use), so no session ends. The auth module's profile image relation is now deferred, which fixes restoring a Postgres dump; step 7's migration carries that change.
argon2 now runs in serverpod_argon2 (BSD-3), a new dependency of the server only: a prebuilt, statically linked library that needs no glibc, bundled by dart build cli like the SQLite libraries, so the Docker build is unchanged. It doesn't reach the app.
The code generator still fails on Dart v3.13's primary constructors in endpoint files (tried again), so the server keeps the four syntax lints off. The regenerated test tools gain withServerpod's ephemeralDatabase option.

Adopts serverpod_offline_sync v0.0.8 (ADR 0001): its module (nickname offline_sync) and the experimental database: sync in generator.yaml, its server and client packages, and overrides that keep the four Serverpod core packages on v4.0.2, since the package pins v4.0.0 exactly and the spike showed it works on v4.0.2. The app's new dependencies come along because the workspace shares one lock file.
Studyset is the first synced model. Its space owns it, so it has no owner column, and only the envelope is a column: keyId and nonce stay null (no end-to-end encryption; ADR 0002, rule 6), and payload holds the content as versioned UTF-8 JSON, so a new content field changes the payload's schema version instead of this table, whose every migration locks older app versions out of syncing (rule 3). The audience column of the original design is gone: it served key selection, and the engine's spaces decide who reads a row.
The generated server and client code is included. The migration isn't: it is created together with the move to Serverpod v4.0.3 and reviewed first, like the client's local migration (the client's lib/migrations is still empty).

The workspace root's analysis_options.yaml includes leancode_lint 27 and enables its analyzer plugin (rules for blocs, Equatable and Flutter layout); the server and the app include that file, while the generated client keeps its own options. Plugins can only be enabled at the root of a pub workspace and only reach packages whose options include the root file, which was verified before settling on this layout. Most rules are warnings, casts, inference and raw types are strict, and the check treats infos as fatal too. lints and flutter_lints are no longer needed.
tool/check.sh checks formatting, runs dart analyze --fatal-infos and the server tests; .git/hooks/pre-push links to it, so every push has to pass it. AGENTS.md describes the checklist and how to install the hook in a fresh clone.
Fixes for the new rules: package imports, run() returns Future<void>, the server setup as one cascade, a primary constructor for the app widget, a const and a redundant argument. The workspace root keeps its conventional name `_` with a documented ignore.

Deviations from a stock `serverpod create`:
- Dropped Flutter web support, for two reasons:
- Appflowy editor had issues in the past, potentially related to the
Flutter-Web IME bridge. Upstream has also open bugs in relation to
that:
- AppFlowy-IO/appflowy-editor#1029 [Bug][Web] Unwanted space on click
and overall space bugs (open)
- AppFlowy-IO/appflowy-editor#782 [Bug] Editor auto-scrolling when
pressing space too quickly if placed inside a scrollable (open)
- Offline-first is a required feature. serverpod_offline_sync's SQLite
support in browsers, maybe via sqlite3.wasm + OPFS, is not
documented.
- SDK constraints raised to ^3.13.0, instead of ^3.12.2, so enjoy the
newest language features.
- Pinned to Flutter 3.47.4 via FVM.
