Added an investor-demo acceptance gate document, updated demo status wording, and added verification that hard-fail conditions cover confusing menus, mannequin-only characters, flat/tan terrain, absent/unreadable foliage, unreadable water, primitive debug objects, non-ray-traced default credibility, and missing visual QA evidence.

+# Investor Demo Acceptance Gate
+
+No packaged build should be called an investor visual MVP unless it passes the
+0.1.O visual/menu acceptance gate and has a real-GPU visual QA evidence set.
+
+## Hard Fail Conditions
+
+The build fails investor visual MVP acceptance if any of these are true:
+
+- menus are confusing, unfocused, unclickable, or do not support predictable
+  back/escape behavior;
+- startup credits, character selection, server/join, loading, pause, save, or
+  quit feel like gameplay is running underneath an accidental overlay;
+- character art is mannequin-only or ignores the selected young-adult male/
+  female archetype;
+- terrain still reads as flat tan placeholder ground;
+- foliage, shrubs, bushes, grass, and trees are absent, unreadable, or hide
+  gameplay-critical objects;
+- water does not read as a collectable freshwater source;
+- campfire, shelter, resources, pickups, or wildlife still read as primitive
+  debug shapes or primitive debug shapes;
+- the non-ray-traced Default rendering path is not visually credible;
+- required visual QA screenshots or clips are missing.
+
+## Required Evidence
+
+Before a package is marked investor visual MVP ready, capture and review the
+evidence listed in `Docs/Ops/PackagedDemoVisualQAEvidence.md`.
+
+Required pass/fail summary:
+
+`Saved\VisualQA\InvestorDemo\<version-or-build>\visual-qa-summary.txt`
+
+The summary must record the package path, version label, rendering preset,
+capture method, tester, pass/fail result, visible defects, and final
+investor-viewing decision.
+
+## Allowed Build Language
+
+If the acceptance gate has not passed, use:
+
+```text
+Agrarian systems-first investor prototype - visual MVP gate pending.
+Not for public distribution.
+```
+
+If the gate passes with current evidence, use:
+
+```text
+Agrarian investor visual MVP preview - internal investor build.
+Not for public distribution.
+```
