Step 4 (c) of ADR 0044 (D20 to D22). - `SharedSpaceKeys`: after each sync, opens the keys members' devices sealed to the person and seals those this device holds to newcomers, space by space, one failing holding back none of the others; keeps each space's latest key, counting only keys whose sealed ID names that space; makes a space's new key and shares it with its members. - `Privacy`: a studyset in a shared space takes the space's latest key, after its own signed record and the key it was last seen sealed with, so a private studyset the instance claims is shared keeps its own key. An item last seen under a space's key is written with that space's latest (D22: earlier rows keep theirs). Writing is refused while no key of the space is open (`spaceKeyMissing`), and a shared studyset is never made readable nor given a key of the person's own (`shared`, D21). Sweeps keep to studysets with a signed record, which a shared one never has. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Signed-off-by: Tizian 「ティツィアーン」 <raisondetredev@pm.me> |

Halkyon
Halkyon's apps and the packages they share, in one repository. Each app is a Flutter app for Linux, Windows, macOS, Android and iOS with a Serverpod server of its own, offline-first, and anyone may run an instance of it: the apps, the servers and everything needed to host an instance are published.
| App | What it is | Where |
|---|---|---|
| Halkyon Learn | Creating, sharing and studying study material, flashcards scheduled with FSRS | apps/learn/, at learn.halkyon.eu |
| Halkyon Todo | To-dos; for now a shell on the shared packages: sign-in, instances, the account | apps/todo/ |
| Halkyon Train | Running, cycling and rowing (ADR 0030); for now a shell on the shared packages | apps/train/ |
Halkyon Meditate is to follow.
Layout
apps/<app>/: each app's server, generated client and Flutter app.packages/: what the apps share, taken by path:halkyon_ui(the look: theme, bundled Noto Sans, layout, shared widgets),halkyon_app(instances, signing in, each person's data and its sync),halkyon_base(what every server has, as a Serverpod module with its generated clienthalkyon_base_client: signing in, the account and its deletion, the pruning, the instance's basics),halkyon_editor(rich text: the editor, its view and the document they keep),halkyon_core(low-level primitives) andhalkyon_interop(contracts between apps).deploy/: what runs an instance (Docker Compose: Caddy, the server, PostgreSQL), learn.halkyon.eu's today.tool/: the checks, the pre-push hook and the release scripts.docs/adr/: the decisions and their reasons.
One pub workspace holds every package: one pubspec.lock, one version of each dependency.
Melos runs scripts across them.
Getting started
- Flutter v3.47.8, the version CI uses (
FLUTTER_VERSIONin.forgejo/workflows/ci.yaml), with each platform you build for set up by Flutter's own guides; what an app needs beyond that is in its README. - The Serverpod CLI v4.0.4:
dart install serverpod_cli@4.0.4. Pass--no-analyticsto every call; otherwise it reports the commands run to Serverpod. - A C++ compiler, for
flutter testtoo: a dependency of Learn's compiles MeCab as it builds.
flutter pub get # every package of the workspace
dart run melos list # the packages
ln -s ../../tool/pre-push .git/hooks/pre-push # the checks before every push
dart run tool/check.dart # format, analysis, every package's tests
dart run tool/check.dart --changed-since=origin/main tests only what changed since
main and what depends on it; dart run melos run test:flutter --scope=<package> one
package's Flutter tests. Each server's tests start an embedded PostgreSQL (no Docker) and
need test passwords in the server's git-ignored config/passwords.yaml (the module's
README and each app's say which). How the code is organised and the rules it follows are
in AGENTS.md and each app's own.
