Halkyon's ADR 0044, step 6c (D7, D49 to D52). apps/learn/halkyon_learn_agent
is one executable, `halkyon-agent --instance URL sign-in | sync | mcp`:
- sign-in keeps the token read from stdin, signs in with it, makes the
agent's key pair on its first sign-in, keeps it before setting the
public halves on the register (agents.setKeys), and syncs;
- it opens its data as the app's _openPersonData does, on
halkyon_learn_core and halkyon_content: its own SQLite database, the
sync's space router, its keys and those of the spaces shared with it,
and the repositories of studysets, cards, notes, paths, files and
feedback;
- mcp serves ten tools over stdio (dart_mcp): list, read and search the
studysets shared with it, suggest a change or a new card or note,
report, list a studyset's suggestions and reply. Each syncs first and
a suggestion again at once; a refusal is the tool's error;
- its files live in $XDG_CONFIG_HOME/halkyon-agent/<host>, 0700 and
0600, refused when others may read them (D50);
- tool/install.sh builds it with `dart build cli` (libsodium and SQLite
bundled) and copies it to its user on the host, the build before kept
(D52).
The synced gateways of learning paths and files, and the fakes of the
core's gateways, move into halkyon_learn_core (its testing.dart), which
the app's tests and the agent's share.
