Six original garage silhouettes — source and device QA

Six fictional offline garage configurations now have distinct cosmetic engine-primitive profiles in the Unreal starter pawn. New IDs are appended, not renumbered. They share the existing physically simulated chassis and collision primitive: this is not six independently modeled production cars.

Saved ID	Garage profile	Engine-primitive outline
0	Arrow	Balanced hood/deck, wingless body
1	Kestrel	Longer hood, shorter deck, low wide rear wing
2	Phantom	Short nose, long deck, higher narrow wing
3	Tempest	Extra-long nose, shallow cockpit, low spoiler
4	Glider	Very short front, longest tail, broad tall cockpit
5	Nova	Extended rear, broadest rear wing, balanced canopy

These are original source-defined dimensions. No third-party car model, manufacturing mark or car audio is embedded. Wings, hood, deck and supports must remain collision-free and unsimulated. Existing first three IDs keep their original tuning values and persistent ownership bits.

Offline progression and save migration

• Profiles 3–5 cost 1,800 / 2,500 / 3,400 earned credits.
• The garage loops only among owned vehicles. The next purchase is the first locked saved ID; no free unlocking when loading a three-car save.
• Saved OwnedVehicleMask and SelectedVehicleId keep existing Unreal int32 schema, with known vehicle bits masked to six. The starter bit is always restored, negative masks are rejected, and invalid/future IDs fall back to Arrow. The game still requires two identical purchase inputs within eight seconds to debit a car.
• Garage UI displays chosen profile number, base acceleration/grip/speed coefficients, next unlock cost and upgrades. These are not performance measurements from a packaged game.
• Career race garage locks and rollback-on-failed-profile-write still apply.

Source verification

Run these from the repository root:

cmake -S Tests/Standalone -B build/garage-tests -DCMAKE_BUILD_TYPE=Release
cmake --build build/garage-tests --parallel
ctest --test-dir build/garage-tests -R 'GarageState|VehicleVisualRecipe|CareerGaragePolicy|CareerLaunchSelection|GaragePurchaseConfirmation' --output-on-failure
python -m unittest discover -s Tests/Editor -p '*Tests.py'

Source policies and binding tests are not Unreal/Chaos integration tests.

Required licensed engine and installed game checks

1. On an authorized Unreal 5.8 Editor/Win64 install, load existing SaveGame containing only bits 0–2 and confirm the old car, bank and upgrades are preserved with IDs 3–5 still locked.
2. Purchase Tempest, Glider, and Nova through two-key confirmations, restart the game, and verify prices, bitmask, selection, persisted bank and no duplicate debit on further confirmation presses.
3. At 720p, 1080p, high-DPI and Android landscape safe areas, verify the garage page's lines remain legible and pagination accessible.
4. Compare actual chase/hood/side views for six distinct silhouettes. Check spoiler supports, wheel/body clipping, shadows, materials, and missing primitive assets. Verify garage selection never changes collision extents or unverified car-handling physics.
5. Exercise a career race and a failed SaveGame write: tuning must remain locked while the career attempt runs; a failed purchase/selection must restore the original car, garage mask and credits.

The original cooked circuit, physically tested vehicle handling, Win64/Android package identity and installed graphical QA gates remain open in issue #148.
