 - [x] Add a visually verified packaged-client startup test using Sunshine/Moonlight or another real GPU desktop capture path, because QEMU guest-agent screenshots cannot validate the interactive rendered desktop. Added a packaged-client GPU startup visual test runbook, a Windows helper that checks the packaged demo and Sunshine service before capture, and verifier coverage requiring Moonlight/Sunshine evidence instead of QEMU guest-agent screenshots.
 - [x] Add first realistic playable character proxies for the selected young adult male and female archetypes, replacing the default mannequin/dummy presentation for investor builds. Added selected male/female MVP proxy application to the player controller, workwear material generation, cook coverage for Agrarian character assets, documentation, and verification so the menu-selected archetype changes the possessed pawn instead of leaving one default dummy presentation.
 - [x] Replace box/sphere/cylinder survival objects with readable MVP meshes for campfires, primitive shelter pieces, resource pickups, water sources, wildlife, and gathered items. Added composed native proxy visuals for campfires, primitive shelters, pickups, resource nodes, water sources, and wildlife using cooked Agrarian placeholder mesh assets plus Ground Zero materials, with child visuals set to no collision so gameplay behavior remains unchanged while investor builds read as intentional objects instead of primitive debug shapes.
-- [ ] Replace the placeholder Ground Zero environment presentation with investor-facing biome dressing: believable terrain material, grass, brush, shrubs, bushes, trees, rocks, water visuals, and local coastal-scrub color variation.
+- [x] Replace the placeholder Ground Zero environment presentation with investor-facing biome dressing: believable terrain material, grass, brush, shrubs, bushes, trees, rocks, water visuals, and local coastal-scrub color variation. Upgraded the repeatable Ground Zero setup to require denser investor-facing foliage counts and twenty-three labeled variation actors covering trees, brush, shrubs, dry grass mats, rock slabs, water-bank pieces, reeds, and freshwater surface material variation, then extended the verifier/docs so the map no longer qualifies if the visual dressing falls back to sparse placeholder presentation.
 - [ ] Add a real water-source visual pass with surface material, edge treatment, scale, and placement that reads as collectable freshwater instead of a placeholder plane.
 - [ ] Add density and sightline tuning so grasses, shrubs, trees, and resource clusters are visible enough to sell the world without hiding gameplay-critical objects.
 - [ ] Preserve realism as the target: use assets, materials, lighting, and environmental dressing that can survive toward MVP production rather than cosmetic throwaways where practical.
