feat: step 7's migration, with an index on spaceId
The first migration since the initial one, created with the CLI (serverpod create-migration --tag studysets), since no MCP bridge was set up yet. On the server it is one transaction that only adds: gen_random_uuid_v7(), the studyset table, the sync engine's tables (spaces, their members and nodes, the CRDT bookkeeping, the log of integrity violations) with their foreign keys, and, from Serverpod v4.0.3, the auth module's profile image foreign key re-created as DEFERRABLE INITIALLY DEFERRED, so that dumps restore. The server tests apply it to their Postgres.
studyset gets an index on spaceId: deleting a space cascades into every synced table, and Postgres doesn't index foreign keys by itself, so account deletion and pruning would otherwise read whole tables. AGENTS.md makes it the rule for every synced table.
The client migration creates each device's SQLite schema. The generator builds it from the whole definition, so it also contains the server's own tables; only the synced tables and the bookkeeping ever hold data on a device.

feat(server): cards and their append-only revisions, synced
Card belongs to a studyset and carries only its position, a fractional index (last writer wins), so cards can be reordered and bulk imports keep their order. Its content lives in CardRevision rows, which are never updated except to blank them (ADR 0001, rule 2): parents lists the revisions a revision replaces (decided: a list, so a revision with two parents resolves a conflict), authorId the writer, reportId the report it answers once reports exist, and the envelope holds the content. Deciding the list of parents and the position now matters: changing a synced table later locks out older app versions.
The migration (created by CLI) only adds: the two tables, an index on spaceId for each (space deletion cascades into them), one for a studyset's cards in order and one for a card's revisions, and the foreign keys, from the space with ON DELETE CASCADE and from the studyset and the card with ON DELETE CASCADE, DEFERRABLE INITIALLY DEFERRED, since synced rows can arrive in any order. The client migration creates the same tables on each device.

feat: studysets record when they last changed; the library lists them so
Decided 2026-10-01: after the starred ones, the library lists the most
recently changed studysets first. That needs a change date, so studyset
gains updatedAt (ADR 0004): when the studyset itself last changed, its
content, place, star or archive date, written by the device making the
change in the same update as the change; the last writer wins. Studysets
from before have none and come last, the newest of them first.
The branch's migration is still unreleased (not merged, not deployed), so it
is recreated rather than followed by a second one:
20261001064926911-tree-tags-assets replaces 20260930213716558 and differs
only by one line on the server, ALTER TABLE "studyset" ADD COLUMN
"updatedAt" timestamp without time zone (nullable, so existing rows keep
null and no data changes), the same column in the table devices rebuild,
and its version. The model's comment on the payload no longer lists schema
1's fields alone.

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()).

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).

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).

feat: PDF sources: read, take notes and cards from pages, deadlines
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: files in an order of one's own, with Reorder beside the tabs
A PDF now has a position among its studyset's files, as notes and paths
have: a fractional index in a column of its own (so moving it on one
device and renaming it on another don't overwrite each other), last
writer wins. The migration adds it to pdf_source on the server and on
each device with 'a0', so PDFs from before stand in the order they were
added (ties sort by id), and new ones go at the end.
The Files tab lists them in that order by default (Custom order, first
in the Sort menu; newest first was the default before). With two files
or more, Reorder beside the tabs shows the custom order whatever they
were sorted by, a grip in place of each file's options and the Sort menu
put away, until Done.
The next release changes synced tables anyway (card.buriedAt, since
v0.2.2), so older apps have to update for that already.
Also: card.position's doc no longer speaks of moving cards.

feat(server): dictionaries, loaded from files and searched
The server now holds dictionaries for everyone: `dictionary_entry` and
`dictionary_source`, reference data owned by no one, never synced. It
loads the dictionary files in its `dictionaries` folder at every start,
those whose SHA-256 changed: in the background, each source replaced in
one transaction, so searches meanwhile find the old entries; a file it
can't read is logged and left out. All of JMdict loads in under half a
minute. On an instance the folder is deploy/dictionaries, mounted
read-only (compose.yaml); the server's README says how.
DictionaryEndpoint (signed in): the dictionaries with their credits; a
search (exact key, exact loose key, key starting with the query, loose
key starting with it, each in the source's order; katakana as hiragana,
macrons written out), some 150-450 ms over all of JMdict; and the
entries with a label, counted and a page at a time (all JLPT N5 words).
The curator now keeps spellings that aren't quite right apart, as
`looseKeys` (romaji with long vowels typed once): "sushi" finds 寿司
before 数詞 (すうし).

feat: dictionaries hold words or characters, and are asked by their source
A dictionary source now says what it holds (`kind`: `words`, the default
for files from before, or `characters`), a string so that an app older
than a new kind leaves it out. Search, countLabelled and labelled take the
dictionary by its source and meaning language, as the unique index names
it, rather than by the language: with KANJIDIC2 beside JMdict, a search
for words would otherwise bring kanji, and JLPT N5 would hold both. The
search reads the language for its query variants from the source's row;
a dictionary the instance doesn't hold finds nothing. The rank index goes
by source too.
Migration: drops and recreates dictionary_entry_rank_idx on (source,
glossLanguage, rank), and adds dictionary_source.kind, text NOT NULL
DEFAULT 'words', so a JMdict loaded before is a dictionary of words. Both
tables are reference data, never synced; the old server keeps working
until the switch (its queries by language just lose the index).
In the app, a studyset's dictionary is one of words unless a kind is
asked for.

feat: a dictionary's corrections reach the cards made from it, by offer
Every dictionary entry now has a version: 16 hex digits of the SHA-256 of
what cards take of it (headword, reading, entry), made by the loader and
carried on every hit. A card keeps the version it took (card schema 8).
DictionaryEndpoint.changed returns, of the entries named with the
versions cards keep (1,000 at most a call; the app asks 500 at a time),
those whose version is another now.
The card browser says how many cards are behind their dictionary and takes
the corrections at a tap (decided 2026-10-09: by offer, never by
themselves). Taking one writes the entry as it is now over the revision
in which the card last took it, beside whatever came after, so the
revisions merge per side as two devices' edits do (ADR 0003): a side only
the dictionary changed takes the correction, a side the person changed
too is a conflict settled in the composer, whose words now name that
case. Cards made before versions are never offered one.
The server rereads its dictionary folder hourly now, not daily: the
dictionaries service fills its volume after an instance's first start,
and an hour with nothing changed costs a hash of each file.
Migration 20261009145434785-dictionary-entry-version: adds
dictionary_entry.version, text NOT NULL DEFAULT '' (rows loaded before
have none and are never reported as corrected), and by hand empties
dictionary_source."fileHash", so every source loads once more and its
entries get their versions; the schema stays as definition.sql says. The
old server goes on working until the switch.

feat: public profiles, a handle on the account domain with name, bio, links and picture
Stage 1 of the public tier (ADR 0005). A person with an identity has a
public profile: a handle by Mastodon's rules (1 to 30 letters, digits or
underscores, unique whatever its case, a few kept for the instance),
changeable until they first publish, on the instance's account domain
(ACCOUNT_DOMAIN, else the server's host; the instance info names it), so
`raisondetredev@halkyon.eu`; a display name, a bio, up to four links and
an avatar. The table is server only: the app gets a Profile without the
person's id. ProfileEndpoint (identified only) reads, saves and removes
the caller's own; ProfilesEndpoint finds anyone's by handle.
An avatar is a PNG of at most 1 MB that the app draws anew from the
picture chosen, its middle square at 400 pixels, so a photo's metadata
never leaves the device. The server keeps it in the public storage named
by its content, so its URL tells nothing about whose it is, and deletes it
once no profile shows it. Deleting a person deletes their profile and its
picture.
In the app, the Profile tab holds the profile as a form, laid out as the
old app's; anonymous people are told GitHub sign-in gives them one.
Migration 20261009184924904-public-profiles creates public_profile with a
unique index on the person and one on the handle in lower case; it touches
no other table, and the old server never sees it.

feat(publish): releases in git (public tier, stage 2)
A person with an identity and a public profile publishes a studyset with
everything inside it as its next release (ADR 0005, rule 3): the server
reads their synced rows and writes them through the git command as a
commit on main and the annotated tag vN, in a bare repository of the
studyset's own, named by a random public id made at the first publish.
A release is a directory per studyset with a file per card, note, path,
step and PDF (its id, position, tag names and payload as synced, keys
sorted and indented) and the files the content names, without what is
only the author's (a card's report, a PDF's deadline). Publishing is
refused without a licence allowing passing it on in every studyset ("no
derivatives" allowed), with revisions to settle, with files not uploaded
yet, when nothing changed, or for a name that won't do; the name is
fixed from the first release, as is the person's handle.
In the app, Share in a studyset's action row opens the Publish sheet;
publishing syncs first, and settles by itself the revisions that merge
cleanly, listing only real conflicts. The server's image gets git, the
repositories a volume of their own, and the hourly backup a git bundle of
each.

feat(explore): list published studysets, give out their releases, withdraw
Explore (ADR 0005, rule 4, stage 3) finds published studysets by fit,
never by popularity: search over titles and authors, the languages (a
primary language takes its regional ones), and the kinds of content they
hold, the newest release first, a page at a time. Each release now keeps
what Explore shows of it (title, description, languages, credits) beside
the repository, so the listing never reads git. Everyone signed in may
look and take a release's files (its JSON, read out of git in one
cat-file run, and each file by its hash) to make a copy of it.
An author can take a studyset off Explore again: nobody can add it then,
copies get no updates, its releases stay; publishing it again, changed
or not, brings it back.
The sync engine's test setup moves into test/integration/support, now
that two test files need it.

feat(explore): how many learn it here, opt-in; copies published within their licence
Explore says how many people learn a published studyset on this instance
(ADR 0005, rule 8): shown, never ranked, counted daily by the server from
the people with an identity who chose to be counted (Settings, Privacy;
settings schema 8) and studied a copy on 3 or more days of the last 30,
rounded down from 5 on, so that nobody can be told apart. Only a number
the instance computes itself counts; votes count for nothing. The author
sees the same rounded number in the Publish sheet.
A copy of a published studyset is published within the original's
licence: never under "no derivatives", under a licence that keeps
adaptations under it only under that one, in every studyset of the copy.
Its releases say what they are based on, and Explore shows it.
ADR 0005 gets an addendum with stage 3's decisions.

feat(feedback): reports and suggestions on published studysets, gathered by the instance
Stage 4 of the public tier (ADR 0005, rule 6), its server and the app's
data. A learner writes a report or a suggestion on a published studyset,
a card, note or step of it, in their own synced space, so it works
offline; replies and the author's decisions (closed, hidden, accepted,
declined) likewise, in the writer's or the author's space. The instance
gathers them: public to everyone signed in, but for what the author
hides; for the author's inbox and the writer's. What counts is decided
as rows are read, since a modified app could write anything: threads
from people with an identity and a public profile the author hasn't
blocked, replies from the writer and the author alone, decisions from
the author alone, no suggestion under "no derivatives". The author gets
the files a suggestion names from its writer's, and the next release
credits the writers of the suggestions accepted since the last
(Co-authored-by). Deleting a person deletes their blocks and what they
read; what they wrote goes with their space.
In the app, the repository writes reports and suggestions (a card, note
or step as the learner has it, without what is theirs alone, with the
files it names) and takes an accepted suggestion into the author's own
card, note or step.

feat(assistant): Claude reads studysets through a connector on the instance
A Claude plan can't drive a chat inside another app, but Claude's apps
(every plan, the phone apps too) can add a remote MCP server as a custom
connector. The instance now is one (ADR 0006): Serverpod's web server
serves the MCP endpoint (/mcp, Streamable HTTP, JSON answers, no
sessions) with five read-only tools over the person's own synced rows
(their studysets, a studyset's cards and notes a page at a time, a
search across cards, a note, their progress), and the OAuth the
specification asks for: protected resource and authorization server
metadata, dynamic client registration, authorization code with PKCE
(S256 only), tokens bound to the resource, iss in the response, refresh
tokens that rotate. Caddy forwards these paths alone to the web server,
which production now runs on 8082.
People connect with a code from the app (Settings › Assistant › Connect
Claude): eight Crockford characters, valid for ten minutes and once,
typed on the authorization page, which names where it returns to, loads
nothing from elsewhere and may not be framed. Anonymous people can
connect too. Codes and tokens are kept only as SHA-256 hashes; an access
token lives an hour, a refresh token 30 days. The app lists what is
connected and disconnects it, which ends its tokens at once; deleting
the account deletes it; a daily job forgets what expired and clients
nobody connected within a week. InstanceInfo says where the connector is
(additive); the migration only adds server-only tables, so devices and
older apps are untouched.
The handlers take plain requests, so the integration tests drive the
whole flow (registration, the code, tokens, refresh, the tools, another
person's content, disconnecting, expiry, pruning, account deletion)

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

feat(publish): a release keeps its colour, and a description for Explore
Publishing takes a description for Explore (rich text, as its JSON),
which Explore shows in place of the studyset's own: a studyset may
introduce itself to strangers otherwise than in the library, where its
author may leave it empty. Without one, as from older apps, the
studyset's description as before; one that isn't rich text, or over
100,000 characters, counts as none. A release also keeps the studyset's
colour, which Explore gives out with it; releases before have none. The
publication's releases say their description, for the next publish to
start from.
Migration release-colour adds a nullable column:
ALTER TABLE "studyset_release" ADD COLUMN "colorName" text;
the server before it reads and writes the table as ever.

feat(auth): sign in with an email address, keeping only a keyed hash of it
People without GitHub can now keep an anonymous account, and sign in on
another device, with an email address and a code mailed to it each time;
no password. The instance keeps only HMAC-SHA256 of the address, keyed
with its emailSignInPepper (ADR 0010): from what someone types it finds
the person and tells whether an address is free, it mails only an address
someone has just typed, and it can't write to anybody otherwise or show
anybody their address. The device remembers the address it signed in
with, in the person's folder, to show it.
It works as GitHub does. A code for a new address makes it the signed-in
person's, who becomes identified and keeps everything. A code for another
person's address gives a switch token, which signs in as them without a
session; a device holding studysets asks first. Asking for a code answers
alike for every address. Codes are eight Crockford characters, valid 15
minutes and three tries (Serverpod's code challenges); three codes an
hour per address, ten per network. In development the code goes to the
server's log; elsewhere there is no email sign-in until a mail service
is set up (instance.info().emailSignIn).
Someone identified may add the other way in: the Profile tab lists how
they sign in and adds GitHub or an address. They are never switched to
another account: an address or GitHub account that is another's is said
to be so. Switching now deletes the account left behind only when it was
anonymous; it deleted any, which only anonymous people could reach so far.
The migration adds email_identity and email_code_request with their
indexes and foreign keys to Serverpod's challenges; nothing else changes.

feat(profile): profile pages on the account domain, and links verified by rel="me"
A profile now has a page on the web, at the root of the account domain
(https://halkyon.eu/@raisondetredev where the operator set ACCOUNT_DOMAIN,
else on the instance's web server), so the address belongs to the
identity rather than to Learn and stays when other services share it
(ADR 0011). The page shows what the app's profile sheet shows, in English
or German, without JavaScript or cookies, asks search engines not to list
it, marks every link rel="me" so other sites can verify links to it, and
sends a visitor who asked on another host to its own address. Caddy
forwards /@… to the web server, and serves nothing else on the account
domain; compose now passes ACCOUNT_DOMAIN on, which it never did.
A link is verified as Mastodon verifies one: its page links back to the
profile's with rel="me". profile.checkLinks fetches each link's page, at
most ten times an hour, over HTTPS on port 443 and to public addresses
only, connecting to the address it checked and verifying the certificate
for the host, with three redirects, 1 MiB and ten seconds at most, and
keeps what links back on the profile (verifiedLinks, a column of a table
no device syncs). A changed link loses its check, a new handle all of
them. The app shows the page's address to copy, checks a link saved by
itself and on Check links, and marks verified links in the form and in
others' profiles; a check answered after a newer save only adds its
checks.

feat(discussions): questions on published studysets, answered by learners
A learner asks about a published studyset, a topic in it, or one card,
note or step of a release, and others answer, as on Stack Exchange
(ADR 0013): questions and answers in the app's editor without images,
sounds or videos, comments of up to 600 characters under the question
and each answer. There are no votes: the asker accepts an answer, which
comes first, then the oldest; the author's posts are marked. The
instance reads from git's file list which topics a question's target
sits in, so a topic lists what is asked within it and below it.
Posts live in two server-only tables, written through endpoints, so the
synced tables stay as they are and v0.17.0 keeps syncing. Everyone
signed in reads; writing needs an identity and a public profile; the
studyset's author hides posts and blocks people with feedback's blocks;
a withdrawn studyset takes no new questions; anyone writes at most 30
posts an hour. A post with others' replies under it is emptied when
deleted, else deleted; deletePerson deletes what a person wrote the same
way, and a published studyset's deletion takes its discussions with it.
The migration adds Serverpod's gen_random_uuid_v7(), discussion_post
and discussion_seen with their indexes and cascading foreign keys, and
changes nothing else.
In the app, discussions open from a copy's studyset or topic menu, a
studied card's "Ask about this", Explore's summary and the Publish
sheet; the Profile tab's inbox lists those the person follows, and its
count includes what is new in them.

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.

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(auth): change the password and the recovery phrase while signed in
ADR 0017, step 3. `password.beginChange` and `password.change` take the
old password's SRP proof and a TOTP or recovery code, and the same keys
wrapped under the new password; a session alone changes nothing, and an
account without a confirmed authenticator is told to set one up first.
`password.setRecoveryKeys` replaces the keys' wrapping under the
recovery phrase for a TOTP code, so a device holding the keys can make
a new phrase.
A change of password ends every other session of the account in every
service of the instance; resets of the password and of the account end
them all. The register ends its own and keeps a notice per member
(`sessions_ended_notice`, a migration that only creates it), told at
once and hourly until it confirms, as deletions are told: it names a
moment, so sessions made since stay, and the session that asked for a
change. A member answering one ends its sessions made before that
moment; a member signing someone in after a reset ends its own first
and makes the new session only once its clock is past the moment.
A reset not due says when it takes effect (`takesEffectAt` on
`PasswordRefusedException`), across members too.

fix(auth)!: the recovery phrase is proved by a key of its own
A key proof was a signature by the account's signing key, which every
signed-in device keeps in its keyring: whoever could read one, with a
code from its authenticator, set a new password without the password or
the phrase (the second reading's H1). The phrase now proves itself with
an Ed25519 key derived from its bits alone (halkyon_keys'
recoveryProofKeysOf, KDF context hlkrprf1, a sibling of the recovery
key), whose public half every setup, new phrase and account reset sends
and the register keeps (account_password.recoveryProofKey); the device
derives the secret half only while the phrase is typed. An account
without one (none exist outside development) proves no phrase until it
sets a new one; decoys check against a decoy proof key alike.
Migration (module, Learn's and Todo's servers, Learn's device schema):
ALTER TABLE "account_password" ADD COLUMN "recoveryProofKey" bytea;
nullable, so rows made before keep working and no data is touched.

fix(auth): codes wait after ten wrong in a row, and the owner is told
Whoever knew the password could guess codes at 10 an hour forever,
unnoticed, each guess checked against every authenticator (the second
reading's M4). Every code an account's second factor refuses after a
right password (sign-in, a phrase's reset, a change) or from a signed-in
device (removing an authenticator, new recovery codes, the code from one
confirmed before) now counts, per account, from every network; after
every tenth in a row no code is taken (codesWait, saying until when), an
hour, then twice as long each time, a day at the most (longestCodeWait,
second_factor_waits.dart): at a day, ten guesses a day still have about a
1 % chance a year against one authenticator, so the first wait mails the
owner that someone knows their password. The instance keeps no address,
so sign-in and the phrase's reset now send the address the device typed
(and its language), used only for that mail after its hash is checked
against the account's. A code accepted clears it all.
Migration (module, Learn's and Todo's servers, Learn's device schema):
CREATE TABLE "second_factor_failures" ("id" bigserial PRIMARY KEY,
"authUserId" uuid NOT NULL, "failures" bigint NOT NULL, "waits"
bigint NOT NULL, "waitUntil" timestamp, "updatedAt" timestamp NOT
NULL) with a unique index on "authUserId": a new table, nothing
touched.

fix(auth): a session's wrong codes end the session, not the account's codes
Wrong codes for removing an authenticator, new recovery codes or confirming
one counted toward the account's waits (the re-review's third finding): a
stolen session alone, without the password, could keep the owner's codes
waiting for up to a day at a time, renewed without end, holding them out
of signing in and of changing the password, the way to end that session,
and nobody was mailed. Those codes now count per session, where the session
is (the register's own, or a member's, which forwards the code): each try
counted before its code is checked (one statement, so tries sent at once
count each), a code accepted clearing the count, and the tenth wrong in a
row ending the session (sessionEnded; the device says it was signed out).
A try that checked no code (a refusal of something else) is taken back.
The account's waits now count only codes after a right password, and the
per-account ten tries an hour, which a session could fill as well, go.
Migration (module, Learn's and Todo's servers, Learn's device schema):
CREATE TABLE "session_code_failures" ("id" bigserial PRIMARY KEY,
"sessionId" uuid NOT NULL, "authUserId" uuid NOT NULL, "failures"
bigint NOT NULL, "updatedAt" timestamp NOT NULL) with a unique index on
"sessionId": a new table, nothing touched. Its rows go with a code
accepted, with the person, and hourly once their session is gone.

fix(auth): a code by mail serves only what it was asked for
Codes by mail were tied to nothing but their address (the re-review's
seventh finding): a hostile instance could answer that a setup never
finished, have the person type a code into it, relay it to start the real
instance's account reset, and 72 hours later relay a second to finish it
with its own password and keys; the mail said "to sign in" whatever the
code was for. A code is now asked for a purpose (signUp, finishSetup,
authenticatorReset, accountReset, deletion), only that purpose takes it (any
other is refused as no longer valid, leaving the code as it was), and its
mail says what it would do ("to reset your account on learn.halkyon.eu: a
new password and new keys, and what was encrypted with the old ones is
lost") and to type it only in the app on that instance, nowhere else. The
app asks for each code with the purpose of its step.
Migration (module, Learn's and Todo's servers, Learn's device schema):
ALTER TABLE "email_code_request" ADD COLUMN "purpose" text; nullable,
so the requests of the last 15 minutes before it stay, taken by nothing

feat(privacy): the instance's side of private studysets (ADR 0019)
- `content_key`, a synced table in the person's space, keeps their data keys
sealed to their account (a private studyset's, their personal one);
`learning_path_answer` gains `keyId` and `nonce` for answers in private
studysets. Additive only, on the server and the device.
- Publishing refuses a private studyset, and a tree holding a private row
(`PublishRefusal.private`); a private studyset elsewhere no longer breaks
publishing a readable one. Encrypted tags are named as the device names
them (`tagNames`): a name for a tag that isn't the person's, or an
encrypted tag of the release without one, refuses it
(`tagNamesMismatch`); a readable tag keeps its own name.
- The connector leaves private studysets out and says how many there are.
- The learner count reads no payload any more: Count me is kept by the
instance (`counted_learner`) and the device reports which publications
its copies come from (`learning_copy`, accepted only while counted, each
report replacing the last); only the reporter's own studysets count.
Deleting a person deletes both.
- An upload says whether its file is encrypted: only a readable one over
20 MB is checked to be a PDF, and an encrypted one may be 4 KiB larger.

feat(assistant)!: no hand-off and no connector; the field searches the web (ADR 0022)
The developer decided on 23 Oct to drop the hand-off to an AI assistant
outside the app, and Claude's connector with it, in v0.19.0, the app and
the server together: build 22 raises minimumAppBuild anyway, so no app
calling the connector's endpoints uses the instance after it. An instance
is to have one way to an assistant, its operator's (ADR 0021, proposed).
The app: the field at the foot of Home, and the button in the Library, on
a studyset and while studying, search the web alone, through the engine
chosen in Settings or Android's own search, with the parts of a card the
person picks; a studyset's name and description are never offered. Gone:
the assistants a question opened in (AiAssistant, AssistantHandOff), the
switch between them and the web, Settings' choice of assistant, Connect
Claude with its route, cubit, repository and gateway, and their texts. A
settings file from before keeps the old keys until the next change of a
setting writes it anew; nothing reads them.
The server: lib/src/assistant/ (MCP, its OAuth, the five tools, connect
codes and tokens), AssistantEndpoint, the daily forgetting of the
connector's secrets (its scheduled call cancelled at start), its lines in
the deletion hook, instance.info().assistantConnectorUrl (nullable, so an
older app reads it as none), and Caddy's forwarding of /mcp, /oauth/* and
/.well-known/oauth-*. The migration drops the connector's five tables,
children first:
DROP TABLE "assistant_token" CASCADE; -- tokens of a connection
DROP TABLE "assistant_grant" CASCADE; -- OAuth codes of a connection
DROP TABLE "assistant_connection" CASCADE; -- a person's connected client
DROP TABLE "assistant_connect_code" CASCADE;
DROP TABLE "assistant_client" CASCADE; -- OAuth clients registered
No other table references them, so CASCADE drops only their own foreign
keys. For the minute between the maintenance run and the switch, the old
server answers the connector with errors and fails to delete an account
(its hook still deletes from these tables); ADR 0022 says so.
BREAKING CHANGE: a connected Claude gets no answer from the deploy on, and
the app no longer opens a question in an AI assistant.

feat(base): SimpleLogin accounts' keys without SRP, signing up in one call (ADR 0020, step 3)
An account that signs in with SimpleLogin keeps its keys under a password
that signs nobody in (D19): `account_password` keeps the password's own
proof key (Ed25519, `passwordProofKey`) in place of SRP's verifier, which
becomes nullable. The migration adds the column and drops the NOT NULL,
nothing else.
- `simpleLogin.signUp(attempt, handle, setup)`: someone new whose identity
waits under the attempt gets, in one transaction, an account
(identified), the link, a profile with the handle and the keys; then a
session (D18). Refused, the identity still waiting, for a setup out of
range and a handle refused as saving a profile refuses it.
- `simpleLogin.checkHandle(attempt, handle)`: whether someone new could
take a handle, at most 30 an hour per attempt and 60 per network.
- `simpleLogin.complete` says, for an account, whether it has its keys and
its handle, and keeps the sign-in ten minutes under its attempt, the
account as its caller: D20's confirmation for the changes to come.
- `keys.begin`, `keys.unlock`: the keys for a signed-in device once the
password is proven with its proof key, for a nonce, bound to the base
URL the device addressed; wrong proofs counted per session as ADR
0017's.
- An authenticator is enrolled only for a password that signs in.
- Members ask the register for all of it; `RemoteRegister` and the
instance API carry the four new operations.

feat(base)!: sign-ups as the operator says, waiting accounts, operators (ADR 0021, step 1)
SIGN_UP takes open (unset), approval or closed; anything else stops the
server as it starts. Closed refuses a SimpleLogin sign-up before its
handle is counted, an address sign-up only once the code has proved the
address, so nothing tells whether an address has an account. Approval
lets a new account wait, at most ten at once: no session is issued for a
waiting or suspended account, only a pass (32 random bytes, kept as its
SHA-256, 30 days, five per account) and four BIP-39 words the operator
reads out to match it. The pass looks, forgets, and deletes an account
that was never approved; nothing else.
Operators hold the scope operator, given first by SQL (D32), then named
in the app: InstanceOperatorEndpoint lists, approves and refuses waiting
accounts, finds accounts, suspends them (ending their sessions), and
names and takes back operators, never the last. account.operating()
counts the waiting for the badge. Members ask the register (five new
operations, a refusal kind signUp), and say closed while it is out of
reach. Never-approved accounts go after 14 days in the daily pruning.
The migration only adds the tables waiting_account and waiting_pass, so
the server before it keeps working on the new schema.
BREAKING CHANGE: a register and its members must run this version
together: a member asks the register operations an older one doesn't
know.

feat(base,learn,todo): the operator's assistants, and the instance's privacy page (ADR 0021, step 2)
The server half of the assistants (points 4 to 8, D27 to D46): the
operator sets language models in deploy/assistants.env, grants them to
people with limits, and the module forwards their questions with the
operator's key, counting what each used, never what was asked.
- assistantsFrom: ASSISTANTS, ASSISTANT_ID_KEY, ASSISTANT_<ID>_NAME,
_PROTOCOL (anthropic, openai, openai-responses), _BASE_URL, _MODEL,
_KEY, _IMAGES, _PRICE_INPUT and _PRICE_OUTPUT (per million tokens),
ASSISTANT_CURRENCY, ASSISTANT_OWN_KEYS; anything unusable stops the
server as it starts, naming the variable.
- The assistant endpoint (identified): offered, agree (D40), ask as a
Serverpod stream (D35): the text as the model writes it, then the
whole turn, sent once the request is counted; figures, the caller's
own. Checked in order: at most 2 questions on their way per person
(tooManyAtOnce), the grant, the agreement, limits in the pricing's
unit now (limitOutdated), the month's and the day's limits (with when
they reset, UTC), the question (malformed, imagesNotRead, tooLarge
past 400,000 characters, an image over 3,932,160 bytes or more than
20 images); output capped at 16,384 tokens. Each request carries the
person's opaque ID (HMAC-SHA256 under ASSISTANT_ID_KEY, D30). Once
sent, the provider's reply is read to its end even if the app
cancels, and counted on a session of its own; a provider's failure is
logged by kind and status, told as providerKey, providerBusy (with
its wait), providerRefused or providerFailed.
- The assistantOperator endpoint (identified and operator, on the
register): setUp, grants, grant (assistantNotSet, invalidLimit,
notFound), revoke, figures of a UTC month.
- Tables assistant_grant and assistant_figures (per person, assistant
and UTC day), in the module's, Learn's and Todo's migrations. The
daily pruning keeps this month and the two before
(forgetOldAssistantFigures, D41); deletePerson deletes both.
A member offers no assistant (D43).
- instance.basics() gains assistantOwnKeys.
- /privacy (D39, addPrivacyPageRoute, on the register's web server,
before the profile pages' route): made from the instance's settings,
English or German, no JavaScript: who may sign up, where the data and
backups are, what the module keeps (the account, sessions, IP
addresses, the server's log), the host's privacyPagePoints (Learn's:
studysets synced, private ones encrypted on the devices with what
stays readable, what is published, dictionary lookups, the learner
count), each assistant with its model and host, what goes and what is
counted, and whether personal keys are allowed. Never a key.
Tests: 70 on the assistants (grants, limits, refusals in order,
streaming, cancelling, counting, concurrency, the operator's denials,
deletion, pruning), 19 on the settings, 8 on the privacy page.

feat(learn): conversations with assistants, kept sealed (ADR 0021, step 3)
The first part of step 3, decided as D47 to D52 in ADR 0021: where a
conversation shows (a sheet over the screen), where kept ones are found
(the field), the scope's chip and that it starts with only what is
ticked, how conversations are kept, and what a device that can't seal
does.
Two synced tables: assistant_conversation (its title, assistant and
scope) and assistant_turn (one question and everything up to its answer,
never changed once written, ADR 0001, rule 2), so two devices continuing
a conversation offline lose nothing. SyncConversationGateway seals every
row with the person's key, a turn bound to its conversation, and reads
no row that isn't sealed: a device that can't seal keeps nothing (D52,
ConversationNotKept). Deleting one blanks it and its turns first (ADR
0002, rule 2). A turn keeps every message a follow-up sends back (tool
calls and results, the providers' own blocks), but no image, only that
one was sent.
The instance's privacy page says conversations are kept, encrypted, and
what the instance sees of them.

feat(base)!: one budget per person for all their assistants, the effort each takes, the operator's lists by page
A grant now says only which assistant a person may use, and keeps their
agreement; the limits are the person's (assistant_budget): one per UTC
day and month in money and in tokens, each optional, money counting the
assistants with prices, tokens every one (Halkyon Learn's ADR 0021, D58,
D59). assistantOperator.grant gives several people several assistants
with one budget, change sets one person's exactly, revoke takes back
everything; grantees and granteesOf list people with their assistants,
budget and use, 50 at a time. The migration carries each person's grant
limits into a budget: per unit, their sum, a grant without a limit making
it none.
assistants.env gives each assistant a default and a highest effort
(_EFFORT, _MAX_EFFORT; refused at start where the provider takes none);
ask takes one within that range, refusing another (invalidEffort), and
caps the output at its ceiling (D63).
instanceOperator.waiting and accounts come 50 at a time from an offset,
and counts gives the rows of the operator's screen (D62).
BREAKING CHANGE: the offer, the grants and the operator's lists changed
shape; Learn's server now asks for build 25.

refactor(base,learn): people's files kept by halkyon_base
ADR 0043, D2, D4, D6 and D7, the first step towards Todo's attachments:
Learn's file store moves into the module, for every server that keeps
files, and Learn becomes its first host.
halkyon_base gets the store as Learn had it: uploads into the caller's
own space by SHA-256, downloads by a row the caller may read, each
person's room (FILE_LIMIT_IDENTIFIED_MB, FILE_LIMIT_INSTANCE_MB, the
operator's file_allowance, which moves into the module unchanged) and
the pruning of files no live row names. It stays free of the sync
engine: a host hands it a FileStore saying which of its rows name a file
and what it takes (HalkyonBase.files); without one the files endpoint
refuses. Its tests, with refusals, run on a stand-in host.
Learn hands it learnFiles: its asset rows, read by their space's members,
a readable file over 20 MB only as a PDF, up to 100 MB. Its app calls the
module; its own asset endpoint stays for released apps alone, forwarding
to the module in Learn's own models, whose names are on the wire. Its
file tests still pass through it, end to end.
Migrations: the module's creates file_allowance. Learn's server migration
holds version rows alone, as tables are matched by name (ADR 0014); its
device migration creates the module's empty table, as every module's.
Todo's, Train's and Meditate's create the empty table.

feat(base,learn): spaces people share, kept by halkyon_base
ADR 0044, step 2 (D1, D2, D11, D13, and D15 to D17, decided today).
halkyon_base keeps the spaces several people share, for every app:
shared_space, its members with their roles (Owner, Editor, Viewer), and
invitations by handle waiting for someone with no account on the
service yet. The sharedSpace endpoint creates a space, lists its
members, invites by handle, changes roles, removes members, hands the
space on, leaves and deletes it.
Who may do what:
- Only people with an identity reach the endpoint.
- A space the caller isn't in can't be told from one that doesn't
exist.
- Members are named by their membership, never by their account's ID.
- Only the Owner manages the members, unless the space lets members
invite.
- The Owner's role passes only by handing the space on, and the Owner
leaves only naming who takes it on.
- An invitation counts as an answer about a handle, as it tells whether
one exists.
Every rule has a test asserting the refusal.
The module stays free of the sync engine: a host hands it a SpaceGrants,
and every call runs in the module's transaction, so the engine's grants
follow the roles or nothing changes. The Owner and an Editor write; a
Viewer reads. Learn hands over SyncSpaceGrants on OfflineSyncSpaces. Todo
hands over none yet, so its server refuses until its projects are
shared.
Deleting an account hands each space the person owns to the Editor who
joined first, else the Viewer who joined first. A space with no other
member goes. This runs before the host's own deletions. A person's first
sign-in on a service makes their waiting invitations memberships, in the
same transaction that makes them a person there.
Migrations: the module's and every host's (Learn, Todo, Train, Meditate)
create the three tables, their indexes and the two cascading foreign
keys to shared_space, and nothing else. The old server keeps working.

feat(base,app,keys): keys of shared spaces, sealed to each member
Step 3 of ADR 0044 (D3, D18, D19). A shared space's data keys are
sealed on a device to each member's public keys; the instance keeps
what devices sealed and never opens it.
- halkyon_keys: the safety code of two accounts' public keys
(`safetyCode`), 60 digits, the same on both sides.
- halkyon_base: the register hands out accounts' public keys
(`public-keys-of`, local and remote); the table `shared_space_key`
and the endpoint `sharedSpaceKeys` (memberKeys, keysNeeded, seal,
mine). Only the Owner and Editors seal, the first key sealed to a
member stays, and a member's keys go with their membership. Every
host's migration creates the table.
- halkyon_app: `ContentCipher` seals a key to another account and
opens one sealed by another; `SharedKeys` shares a space's key with
its members, seals keys to newcomers and opens the person's own,
holding each member to the public keys `KeyPins` pinned on first
sight (`key_pins.json` in the person's folder), a change refused
until trusted anew.
Learn takes them into its `Privacy` in step 4.
