-- [ ] Can launch packaged client.
+- [x] Can launch packaged client. Added an MVP QA gate that requires the Windows package script, packaged executable, installed investor launchers, and the real-GPU visual QA readiness check before the client launch gate qualifies.

+# MVP QA Gates
+
+Version `0.1.Q` turns the current survival MVP into a repeatable test target.
+Each gate must have either automation, a documented manual test, or build
+evidence before it is marked complete.
+
+## Packaged Client Launch
+
+The packaged client launch gate proves the Windows investor/demo package can be
+created, opened through a known launcher, and checked through the real-GPU
+visual QA path.
+
+Required evidence:
+
+- `Scripts/PackageWindowsDevelopment.bat` completes successfully.
+- `Builds/WindowsDevelopment/AgrarianGame.exe` exists.
+- `Scripts/InstallWindowsDemoLaunchers.bat` installs:
+  - `Start Agrarian Demo.cmd`
+  - `Start Agrarian Demo - DX12.cmd`
+  - `Start Agrarian Demo - Compatibility DX11.cmd`
+- `Scripts/RunWindowsInvestorVisualQACheck.bat --check-tools` reports the
+  packaged demo exists and `SunshineService` is running.
+- Any full visual pass stores notes under `Saved\VisualQA\InvestorDemo`.
+
+This gate is client-only. It does not require multiplayer server deployment.
