TrainPerson now opens the person's own sync database in their folder, halkyon_app's SyncService behind AppCompatibility (the module's basics' minimumAppBuild against the build package_info_plus reads), their key and their workouts, and closes them in that order, the key last. As in Learn, a person's data waits for the one before to close, since signing in again opens the same database. The pubspec's dependencies are sorted again (clock had gone before flutter).

# Halkyon Train
|
|
|
|
What holds for every app and package of this repository is in the [root AGENTS.md](../../AGENTS.md); it applies here in full, and Learn's patterns (`apps/learn/AGENTS.md`) wherever Train needs the same thing.

- **A shell on the shared packages**, Todo's copied and renamed (decided 2026-10-28, ADR 0030, D12; what Train is to do: ADR 0030): signing in, the instances, the account and the look work, and since step 5a (28 Oct 2026) a person's workouts are kept and synced with `serverpod_offline_sync`, every row sealed (ADR 0030, D7, D14, D15), though no screen records or shows them yet (5b, 5c). Packages: `halkyon_train_server`, `halkyon_train_client` (generated, never edited), `halkyon_train_flutter`; app ID `app.halkyon.train` on every platform; no web build. Licences as Learn's (server SSPL, client and app AGPL; `LICENSE.md`).

- **The server** includes `halkyon_base` (ADR 0014) and configures it in `server.dart` (`trainBase()`, `lib/src/train_base.dart`): its basics say it serves `train` (never change it once apps use it), sign-in mails name Halkyon Train, the source is this repository, `minimumAppBuild` 1, and `deleteTrainData` (`lib/src/train_data.dart`) as its `deletePersonData` hook, which deletes the person's sync spaces and so, by the sync engine's cascades, every row of theirs (`test/integration/workout/person_deletion_test.dart`). Authentication through the module's builders: a password, SimpleLogin on the register, email codes proving an address, server-side sessions; no anonymous accounts (ADR 0020, D25), nor GitHub (D36). **Accounts** (ADR 0016): Train holds its own register when it runs alone, and is a member of the instance's register (Learn's server on learn.halkyon.eu) where the operator sets `ACCOUNT_REGISTER_URL` (`trainBase(accounts: AccountsMode.fromEnvironment())`) with the instance's shared `INSTANCE_SECRET` (`instanceSecret`); then sign-in, handles and profiles are the register's, the email settings are the register's alone, and an identified person's deletion goes to the register first. `addInstanceRoutes` serves the calls between the services on its web server, and the server doesn't start without the secret where it needs it. `schedulePruning` (`lib/src/pruning.dart`) keeps the module's pruning scheduled, one entry each however often the server starts (and cancels the one under the pruning's name before ADR 0020, D25): the anonymous accounts left from before daily, sign-up attempts and codes hourly, as the register the deletions its members haven't confirmed hourly, as a member the people the register no longer knows daily (each a no-op in the other mode). Session logs are never persisted, in any run mode. Migrations (2026-10-28): an initial one with Serverpod's tables, its auth modules' and the module's as they stand (Todo's grew one by one with the module; Train starts where they ended), then `workouts`, purely additive: the sync engine's tables and Train's first three. **Synced models** (`database: sync`, the module `offline_sync`, `experimental_features: databaseSync` in `config/generator.yaml`): `content_key` (the person's key sealed to the account), `workout` and `workout_series` (a workout's series in chunks of at most ten minutes, deleted with it), each a sealed `payload` with its `keyId` and `nonce`, nothing else readable. Tests (`test/integration/train_server_test.dart`) call the module's endpoints through the server's own dispatch (`halkyon_base.<endpoint>`), since the generated test tools expose the project's endpoints alone.

- **The app** is halkyon_app's `InstanceGate` and `SessionGate` with Train's frame (`trainFrame`: "Train" under "Halkyon", its icon, `train.example.org`, its own sentence) and `ServerpodInstanceChecker(app: 'train')`; `TrainDependencies` (`AppDependencies<TrainPerson>`) on one instance, `TrainPerson` per person: their own sync database in their folder (`sync.sqlite`, halkyon_app's `PersonFolders`, one person's at a time), halkyon_app's `SyncService` behind `AppCompatibility` (the module's basics' `minimumAppBuild`, against the build `package_info_plus` reads), their key (`TrainKeys`, `lib/src/core/privacy/`: one key per person, IDs `train1.<ms>.<nonce>`, the oldest-made writing, kept in `content_key` and opened only in Train's form, ADR 0030, D15) and their workouts (`WorkoutRepository`, `lib/src/feature/workout/`: halkyon_app's `PayloadEnvelope` seals a workout for its row and a series chunk for its row and its workout; payloads are versioned JSON, a series' columns delta-coded, gzipped before sealing; a deletion blanks every payload first); the gateways' tests run on a sync database opened without a server, the repository's on memory gateways and real libsodium; a person's app with an empty home and the account sheet: halkyon_app's `AccountTiles` (whose account on which instance, Switch account, Sign out, Delete account, which asks first) in Train's words, and halkyon_app's About (`showAppAbout`: the source of what the instance runs, from `TrainDependencies.sourceCodeUrl`, and the licence list). Texts through gen-l10n in British English (the template), German (informal du), an empty `en_US` and `en_GB` (`test/l10n/arb_files_test.dart` keeps them in step). The look follows the system's theme mode and language until Train has settings. Countries in where an instance keeps its data are named by halkyon_app's CLDR names (`AssetCountryNames`), its language picked by halkyon_app's `resolveAppLocale`. Widget tests start Train's whole tree with halkyon_app's fakes (`test/app/train_app_test.dart`).

- **The icon** is Lucide's `bike` fading from cobalt through violet and strawberry into carrot (ADR 0031), drawn with the other apps' by the repository's `tool/app_icons.py` (`python3 -I tool/app_icons.py train` from the root): `assets/icon/halkyon_train_icon.png`, Lucide's ISC licence beside it, and every platform's launcher icon through flutter_launcher_icons. `registerLucideLicense` puts Lucide's notice in the licence list.

- **`serverpod start`** runs in `apps/train/halkyon_train_server` (it launches the app from `lib/driver.dart`); `.mcp.json`'s `--server-dir` names it when a session works on Train. Its tests need throwaway passwords in its git-ignored `config/passwords.yaml` (`database`, `serviceSecret`, `serverSideSessionKeyHashPepper`, `emailSignInPepper`) or from the environment, as CI gives them. Train's development server has ports of its own (API 8180, Insights 8181, web 8182, PostgreSQL 8190; the app's `assets/config.json`), so it runs beside Learn's, as a member of Learn's register; its tests use `config/test.yaml`'s ports, as Learn's and Todo's do, which Melos runs one package at a time.
