feat(server): the instance names where its source is
Both licences (AGPL for the app, SSPL for the server) require offering the source of what an instance runs to the people who use it. instance.info() now carries sourceCodeUrl: the operator's SOURCE_URL, which they must set when running modified code, and otherwise this project's repository. Serverpod validates its configuration files strictly, so the value comes from the environment; deploy/compose.yaml passes it on from deploy/.env, whose example explains it. A test covers the default.

feat(server): GitHub sign-in that keeps only the GitHub ID
As decided, a GitHub sign-in keeps nothing but the numeric GitHub ID, so the login is our own, on Serverpod's GitHub helpers (lib/src/auth/github.dart): Serverpod's stock login also stores the name and email in a profile and downloads the avatar, and its endpoint is never exposed. The server exchanges the authorization code with the client secret, reads the ID, and drops the access token.

GitHubUpgradeEndpoint links the GitHub ID to the signed-in anonymous person, grants identified (to their existing sessions too) and removes the anonymous identity, in one transaction: the person, their spaces and their studysets stay the same. GitHubSignInEndpoint gives a session for a person who has the GitHub account already; it's called without a session, since Serverpod issues no session for another person inside a signed-in call, and it never creates people. InstanceEndpoint.info() tells the app the instance's GitHub client ID. Refusals are GitHubSignInRefusedException with a reason: GitHub sign-in off here, the account taken by another person, another GitHub account linked already, an unknown account.

GitHub sign-in is on only where the passwords hold githubClientId and githubClientSecret (empty counts as missing, as Compose passes unset variables on as empty strings); production takes them from GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET in deploy/.env. grantIdentified can now join a caller's transaction. No migration: the GitHub accounts table comes with the auth module.

Tests, refusals first: upgrading when not signed in (checked by switching the guard off: the test fails), both ways without a GitHub app, an account taken by someone else with nothing changed, a second GitHub account, an unknown account with nobody created; then linking keeps the person and reaches their sessions and stores no email, linking twice changes nothing, signing in reaches the right person.

feat(server): studysets, the first synced table (migration pending)
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).

feat(server): the authorization pattern, with "Your devices"
Serverpod has no row-level security, so every endpoint enforces access itself, by three rules established here once: the person comes from the session, never from the client, and every query filters by them; someone else's row answers exactly like a missing one (NotFoundException, shared in lib/src/common); endpoints for people with an identity declare requiredScopes: {identified} instead of checking it themselves.

DevicesEndpoint is the first such endpoint: it lists your sessions and signs one of them out, for a lost phone. It uses the existing session table, so no migration. Serverpod's own helpers are unguarded (revokeSession deletes by id alone; listSessions without authUserId returns everyone's sessions), so the endpoint puts the owner check into the same query and then notifies the revoked device as revokeSession does. Each query carries its SQL as a comment.

The identified scope lives in lib/src/auth/scopes.dart. grantIdentified gives it to a person and to their existing session rows, because sessions keep the copy of the scopes they were started with; step 9 uses it.

Tests assert the refusals first: anonymous people and callers who aren't signed in are refused; the list shows only your own devices; signing out someone else's device fails exactly like an unknown id and leaves it alone; grantIdentified reaches existing sessions. The shared fixtures live in test/integration/support. AGENTS.md names the endpoint as the reference and warns about the unguarded helpers.

feat(server): anonymous sign-in
People can sign in without an account: AnonymousIdpEndpoint exposes Serverpod's anonymous identity provider. lib/src/auth/auth_config.dart holds the token managers and identity providers, shared by server.dart and the tests, so the tests check what production runs. At most 30 new anonymous accounts per IP address and hour (Serverpod's default is 100): a school class behind one address can still start together, while one abuser gets at most 720 a day. No migration: the tables for anonymous accounts and rate limiting already exist.

Tests: signing in creates a person; the 31st account from one IP address within an hour is refused. They run without database rollback, since signing in uses concurrent transactions that the rollback can't wrap, and delete what they create instead.

The server switches off the lint rules for Dart v3.13's constructor syntax: Serverpod v4.0.2's code generator can't parse it yet.

chore: scaffold the Serverpod 4 build
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.
