Opus review of LA3 returned FIX FIRST; this addresses every finding in
scope (F1-F5, F7-F12; F6 CI-lane addition excluded per instructions):
- F1 (CRITICAL): SessionProcessSettings.Paths is now nullable and left
null by SessionConfigComposer unless a caller supplies overrides, so
the JSON key is entirely absent instead of "paths":{} — the App-side
loader's strict UnmappedMemberHandling.Disallow would otherwise reject
every gui/guiSelect session-config document at load.
- F2: added SessionConfigComposer.ComposeProbe and a nullable
SessionDescriptor.Mode field ("probe", omitted for normal play) per
the pinned contract — no character/policy/plugins/loginCommands.
- F3: LauncherProcessSupervisor.Stop now tries
ILauncherChildProcess.TryRequestGracefulStop (Linux: libc SIGINT via
LibraryImport, K4-proven graceful headless logout) before
CloseMainWindow. Windows has no reliable no-window-console equivalent
today; filed docs/ISSUES.md #397 with the CREATE_NEW_PROCESS_GROUP +
CTRL_BREAK fix direction. Stop()'s blocking-timeout contract is now
documented for LA4.
- F4: LauncherProfileStore.Save chmods the Linux temp file to 0600
immediately after creation, before any credential is serialized;
failure paths and Load() clean up a stale .tmp.
- F5: added LauncherCoreDependencyBoundaryTests asserting Launcher.Core
references exactly AcDream.Platform and no packages.
- F7: StatusEventParser.Parse no longer throws on a whitespace/null
line; StatusFileTailer.ReadNewEvents swallows the File.Exists/open
TOCTOU window (FileNotFoundException/DirectoryNotFoundException/
IOException) instead of throwing.
- F8: Start() now kills (entire process tree) and disposes a child that
started successfully but failed while being fed its stdin password,
instead of orphaning it.
- F9: SetState is monotonic — once Exited, no later transition applies
or fires StateChanged, closing a Start()-path race where a
synchronously-exiting child could be "resurrected" to Running.
- F10: CharacterIdFormat.TryParse now requires the "0x" prefix (an
unprefixed hand-typed decimal id is also valid hex and was silently
misread); a parsed id of 0 is treated as unusable and falls back to
the name selector; LauncherProfileStore.MergeRoster normalizes both
sides through TryParse/ToHexString instead of raw string equality, so
a legacy unprefixed-hex row self-heals via name match instead of
duplicating.
- F11: StatusCharacterEntry.SecondsGreyedOut is now uint, matching
CharacterRosterEntry and the host writer.
- F12: added MalformedStatusEvent, returned for a recognized `e` whose
payload doesn't match its shape, distinguished from UnknownStatusEvent
(an unrecognized `e`).
AllowUnsafeBlocks was added to AcDream.Launcher.Core.csproj — required
by the LibraryImport source generator's function-pointer marshalling
stub for F3's Linux SIGINT P/Invoke.
Verification: dotnet build AcDream.slnx -c Release green (0 errors);
dotnet test tests/AcDream.Launcher.Core.Tests -c Release green at 94/94
on native Windows and under WSL (Ubuntu, verified across multiple runs
for the timing-sensitive SIGINT/sharing-violation tests, no flakes
observed).

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.
