refactor!: packages, paths and app IDs under Halkyon Days' names (ADR 0045, step 3) Learn's folder is apps/halkyon, Todo's apps/myrmex; every package of ours takes the prefix halkyone_ (halkyone_halkyon_*, halkyone_myrmex_*, halkyone_train_*, halkyone_meditate_*, halkyone_app, halkyone_base_* and the other shared ones; halkyon_oidc_* keeps its name, D11). Halkyon and Myrmex take the app IDs one.halky.halkyon and one.halky.myrmex (D10); Train and Meditate keep theirs, while every app's Android namespace, Kotlin package and method channels move to one.halky. The snaps are halkyon and myrmex (D17), each built in a clone with its recipe in place of snap/, as Train's and Todo's were. Serverpod finds a database's migrations by its module's name, which changed with the packages': - each server's new, empty migration ("rename") records itself under the new names and deletes the rows under the old ones; - deploy/redeploy.sh copies each database's record to the new name before the migrations (carry_module), so the renamed servers find their databases migrated; a copy, never a move, so a deploy failing before the migration commits leaves the old rows in place; - Train and Meditate keep their devices' databases: halkyone_app's carryMigrationRecord copies their record before the sync engine opens them (openPersonDatabase); - the client migrations' generated moduleName getters, one line each, say the new names: Serverpod's client asserts in debug builds that every migration names the module, and create-migration never writes a migration's files again. Train's WorkManager work is enqueued under new names, the former ones cancelled: the work kept names the workers' former classes. The release tool: an app's tags of its earlier names count as its history (legacyTagPrefixes), the shared packages' former paths count for its version, and every snap is built in a clone (atRoot gone). The databases, Docker images and Compose project keep their names until step 5. BREAKING CHANGE: Halkyon (Learn) and Myrmex (Todo) are new apps to Android and the Snap Store: installs of app.halkyon.learn and app.halkyon.todo don't update to them.

The servers and the module build on Serverpod's core, which is under the SSPL, and so are
under it too. The apps and the shared Flutter packages link only permissively licensed
packages (the apps' icons are Lucide's, under the ISC licence, whose notice each app registers), and the client packages are generated from our own model definitions, so all of
them are under the AGPL. One exception: Train's Android build links Polar's BLE SDK for
the Polar Loop, under Polar's own, non-free licence (Train's ADR 0030, D36), which the
app's added permission allows; its notices are in the app's licence list, and an F-Droid
listing of Train is to declare `NonFreeDep`. The curator depends on neither a server nor Serverpod: Learn's
server reads the files it writes, never its code.
Everything else in this repository (tooling, documentation, deployment files) is under
`AGPL-3.0-or-later` unless a file says otherwise.
