The launcher spawned the headless host as
acdream-headless --config <path>
but HeadlessCommandLine.Parse reads arguments[0] as the COMMAND and accepts
only "validate" or "run". So every launcher-started headless session and every
"Refresh characters" died on its first instruction with
Invalid command. Run --help for usage. (exit 64)
The user's own cache shows it six times over two days. It was invisible because
the failure is an exit code in a status file, not something the UI says out
loud — which is how it survived a whole campaign whose gates exercised the
headless host through its CLI directly, never through the launcher's spec.
The graphical host takes a bare "--session-config" and has no command word;
this sibling call was written to match it. Both headless call sites now pass
"run" first. A probe is an ordinary "run" whose session config carries
mode: "probe" — the difference is in the document, not the command line, so
one fix repairs refresh and headless play together.
LauncherHeadlessCommandLineContractTests is the connection that was missing:
it takes the argument vector the launcher will really use and hands it to the
parser the host will really use, for probe and for headless play, and pins that
the graphical arguments are deliberately NOT a headless command line. The two
sides cannot drift again without failing here. Headless.Tests already
referenced both assemblies, so this needed no new coupling.
Also LU7, at the user's direction: a selected character now offers only Play
and Headless. Choosing a character means choosing to play AS that character, so
"Character select" — which deliberately picks no character — belongs to the
account page alone, where it already lives. The per-character GuiSelect command
and its capability are removed rather than left as dead surface.

GameWindow.Dispose() (via Program.cs's `using var window = ...`) runs
unconditionally even when invoked mid-unwind of an exception that escaped
Run()'s Silk.NET frame loop. Resource teardown itself can converge
cleanly regardless, so CompleteShutdown had no way to tell "normal Run()
return" from "a crash is propagating through me right now" and always
wrote the hardcoded exited{code:0,reason:"graceful"} — exactly the
symptom #406 observed against a real 0xE0434352 crash. Fixed by latching
_runFailure in Run()'s existing catch block (before the pre-existing
throw) and consulting it from a new ReportExited method, the one call
site for the terminal status write: crashed(1)/graceful(0)/
shutdown-incomplete(1) as appropriate. No wire-contract amendment needed
— §LA1 pins the exited event NAME, and reason is already free text that
StatusEventParser round-trips unchanged.
Sibling gap fixed in the same commit: the launcher discarded the child's
stdout/stderr entirely, which is why diagnosing this exact crash required
a manual console re-run. Added BoundedProcessOutputCapture, a 2 MiB-capped
sink mirroring SessionStatusWriter's open-append-flush-close-per-write
posture (a long-lived write handle is not actually concurrently readable
on Windows even with FileShare.Read — confirmed by isolated repro), wired
into both SystemChildProcess (ProcessStartInfo.RedirectStandardError;
Linux + Windows graphical children, i.e. this bug's own scenario) and
WindowsSystemChildProcess (a real native pipe via CreateChildOutputPipe,
mirroring the existing stdin pipe; Windows console-capable/Headless
children). Opt-in via LauncherProcessSpec.StderrLogPath (null = unchanged
behavior), threaded through SessionConfigComposer -> client.err.log
beside status.jsonl -> LauncherExecutableSet -> LauncherOrchestrator.
Tests: GameWindowCrashStatusTests (source-shape, matching the existing
GameWindow test pattern — the class cannot be constructed without a live
GPU/window), BoundedProcessOutputCaptureTests (10 unit tests), and three
new LauncherProcessSupervisorTests spawning real child processes through
both capture code paths.
Launcher.Core.Tests: 337/0 (was 324/0). Launcher.Tests: 67/0 (unchanged).
Full solution build green.
