Run 173's Linux job failed on the contract test added one commit earlier — my
test, not the product.
LauncherExecutableSet refuses a host that exists but has no execute bit on
Linux (HasUnixExecutePermission), which is a real and useful check: an update
whose extraction lost its permissions would otherwise fail deep inside process
start instead of at the launch gate. The stubs were written with
File.WriteAllText, which is 0644, so on Linux every one of the four tests died
at that gate before reaching the command-line contract they exist to pin.
Windows never sees this — the predicate short-circuits to true off Linux — so
the test passed locally and could only fail on the runner.
Stubs are now created through a helper that chmods them executable on non-
Windows. Verified on Windows (4 passed); the Linux half is what run 174 checks.

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.
Full solution 14,374 passed, 0 failed under the release-gate filter.
