ADR 0044's D49 (amended in building it): what reads and seals Learn's content moves out of the Flutter packages, so Learn's agent, which runs without Flutter, shares it rather than repeating the privacy rules. packages/halkyon_content (new, pure Dart) takes from halkyon_app the envelope and its cipher, SealedFile, UnlockedAccountKeys, shared spaces' gateway with SharedKeys and KeyPins, FileCache and FileServerGateway, with their fakes and tests; halkyon_app exports it, so no app changes. Its rich_text.dart takes RichContent from halkyon_editor, which exports it. newAccountKeys makes an agent's key pair. halkyon_core takes DelayedDeletions and gains SyncRequests, what a synced gateway asks of the sync, which SyncService implements. apps/learn/halkyon_learn_core (new, pure Dart) takes Learn's privacy, sync, payloads and the models, codecs, gateways and repositories of studysets, cards, notes, tags and feedback, with what they reach of files, learning paths, citations and study options; the app imports them from there. A subject's icon, colour and name stay in the app (SubjectLook); what only the app shows (progress, exam coverage, the card browser, deletions' waits) stays too. Nothing changes for people using the apps. 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_content
What seals and opens a person's synced content, in pure Dart (Halkyon's ADR 0044, D49), so
that Learn's agent, which runs without Flutter, seals and opens rows as the apps do. The apps
take it through halkyon_app, which exports halkyon_content.dart, and rich text through
halkyon_editor, which exports rich_text.dart.
| Library | What it holds |
|---|---|
halkyon_content.dart |
The envelope every synced row is sealed in (PayloadEnvelope on a ContentCipher, SodiumContentCipher; ADR 0019), a file sealed alike (SealedFile, HLKF); the account's unlocked keys (UnlockedAccountKeys) and new ones for an account without a password (newAccountKeys, an agent's); shared spaces through the module (SharedSpaceGateway) and their keys, sealed to each member and held to the public keys first seen (SharedKeys, KeyPins, ADR 0044, D3, D18, D20); people's files on the device and the module's store (FileCache, DirectoryFileCache, FileServerGateway; ADR 0043) |
rich_text.dart |
RichContent, the editor's document JSON, and the names of its blocks (content_blocks.dart), which halkyon_editor edits and shows |
testing.dart |
Fakes: FakeContentCipher, FakeSharedKeysGateway, FakeSharedSpaceGateway, MemoryKeyPinStore, FakeFileServerGateway, MemoryFileCache |
sodium's build hook compiles libsodium, so every machine that builds or tests it needs a C
compiler and make (as for halkyon_keys). Licensed under the AGPL-3.0, as the apps.
