fix(launcher): Campaign LA LA3 review fixes — contract paths omission, probe composition, graceful stop, hygiene
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).

## #397 — Windows: LauncherProcessSupervisor.Stop has no reliable graceful-stop signal for a no-window console host
|
||||
|
||||
**Status:** OPEN
|
||||
**Severity:** MODERATE (a hard-killed `AcDream.Headless` leaves the ACE
|
||||
account session stuck for several minutes — a documented project landmine;
|
||||
see CLAUDE.md "Logout-before-reconnect")
|
||||
**Filed:** 2026-08-14 (Campaign LA plan §LA3 review-fix round, finding F3)
|
||||
**Component:** Launcher.Core / process supervision
|
||||
|
||||
**Description.** `LauncherProcessSupervisor.Stop` now attempts a graceful
|
||||
stop signal (`ILauncherChildProcess.TryRequestGracefulStop`) BEFORE
|
||||
`CloseMainWindow`. On Linux this sends `SIGINT` via a `libc` P/Invoke
|
||||
(`kill(pid, 2)`), which the K4-proven headless host already turns into an
|
||||
ACE-confirmed graceful logout. On Windows there is no equivalent today for a
|
||||
console process with no message-pump window: `CloseMainWindow` is a no-op
|
||||
for a console host (there is no `HWND` to target), and
|
||||
`GenerateConsoleCtrlEvent` cannot usefully target an arbitrary child process
|
||||
today — Windows delivers console control events to every process attached
|
||||
to the SAME console as the calling process, so an unscoped call would also
|
||||
signal the launcher itself (and anything else sharing that console), not
|
||||
just the intended child. `TryRequestGracefulStop` therefore returns `false`
|
||||
on Windows unconditionally, and `Stop` degrades straight to `CloseMainWindow`
|
||||
(still a no-op for a console child) and then the timeout-driven `Kill()` —
|
||||
exactly the hard-kill behavior this finding was written to describe, just
|
||||
with a documented (rather than silent) gap.
|
||||
|
||||
**Known fix direction (not yet implemented).** Spawn the Windows child with
|
||||
the `CREATE_NEW_PROCESS_GROUP` creation flag (available via a native
|
||||
`CreateProcess` call or by setting it on the `ProcessStartInfo`/`Process`
|
||||
plumbing in `SystemChildProcess`) so the child gets its own console process
|
||||
group, detached from the launcher's own group. Then
|
||||
`TryRequestGracefulStop` on Windows calls
|
||||
`GenerateConsoleCtrlEvent(CTRL_BREAK_EVENT, childProcessGroupId)` —
|
||||
`CTRL_BREAK` (unlike `CTRL_C`) can target a specific process group ID and,
|
||||
unlike `CTRL_CLOSE`/`CTRL_LOGOFF`/`CTRL_SHUTDOWN`, is deliverable to a
|
||||
process that has installed no console-control handler at all (the default
|
||||
CRT handler treats it as a terminating signal, so `AcDream.Headless` doesn't
|
||||
strictly need new code to receive SOME form of shutdown from it) — though
|
||||
wiring a real `SetConsoleCtrlHandler` handler that routes `CTRL_BREAK` into
|
||||
the same graceful-shutdown path K4 already built for Linux SIGINT is the
|
||||
better long-term target, so a Windows headless launch gets the identical
|
||||
ACE-confirmed graceful logout instead of just "exits somehow."
|
||||
|
||||
**Acceptance for closing this issue:** `SystemChildProcess` spawns Windows
|
||||
children with `CREATE_NEW_PROCESS_GROUP`; `TryRequestGracefulStop` sends
|
||||
`CTRL_BREAK_EVENT` to that child's process group on Windows; a live
|
||||
connected gate proves `AcDream.Headless` exits gracefully (ACE clears the
|
||||
session immediately, not after the ~3-minute stale-session window) when
|
||||
stopped via `LauncherProcessSupervisor.Stop` on Windows, matching the
|
||||
Linux SIGINT behavior.
