New AcDream.Launcher.Core (BCL-only, ProjectReference: AcDream.Platform
ONLY) plus tests/AcDream.Launcher.Core.Tests, both registered in
AcDream.slnx. This is the file-contract orchestrator core the Avalonia
launcher (LA4) will bind to — the game solution (Core/Runtime/App/
Headless) stays entirely out of this dependency graph, so the launcher
can never accidentally grow a game-protocol coupling.
- Profiles/: LauncherProfileStore owns launcher-profiles.json (spec §5
schema: version 1, servers[]/accounts[]/characters[]), strict
camelCase System.Text.Json (UnmappedMemberHandling.Disallow), typed
CRUD (add/edit/remove server; add/edit/remove account; edit character
settings), and MergeRoster (fold a reported roster into an account's
characters[] while preserving user-owned launchMode/plugins/
loginCommands, adding new rows with default guiSelect, and retaining
rows absent from the roster — they may be pending-delete). 0600 on
Linux via File.SetUnixFileMode after save.
- Launching/: SessionConfigComposer builds the pinned session-config
contract (Headless K1 shape + plugins/loginCommands/
loginCommandDelayMs/statusFile) from a profile character + install
record — character selector omitted entirely for guiSelect, policy
{id:"idle"} only for headless, credential always standardInput/
session. Passwords never enter this document (proven by a dedicated
test). LauncherProcessSupervisor spawns a host, feeds the password to
stdin then closes it, and exposes Starting/Running/Exited lifecycle;
Stop calls CloseMainWindow falling back to Kill after a timeout, both
reachable through an injectable ILauncherChildProcess/factory seam so
the state machine is unit-testable without real OS process timing.
- Status/: StatusEventParser decodes the v1 status.jsonl vocabulary
(started/connected/characterList/enteredWorld/pluginLoaded/
pluginFailed/disconnected/exited); an unrecognized "e" or a malformed
line degrades to a typed Unknown event rather than throwing.
StatusFileTailer incrementally reads new lines, tolerating a
not-yet-existing file and a partial trailing line (only advances its
read position past confirmed '\n' boundaries; a truncated tail is
simply re-read next poll, never parsed early).
- Integrity/: streaming SHA-256 + hex verify for later pak/download
checks (LA9/LA10).
Tests: 71 passed (profile CRUD + roster-merge matrix + strict-schema
rejection; composer golden-shape tests for gui/guiSelect/headless +
password-absence; supervisor tests against both an injected fake child
(state-machine determinism) and a real spawned `dotnet --version`
child (genuine cross-platform stdin/exit-code proof); tailer tests
incl. partial-line and not-yet-existing-file; SHA-256 tests). Verified
green on Windows (Release) and native WSL/Linux (Release) — the Linux
0600 test executes its real assertion body under WSL rather than
early-returning.
