Garage spending confirmation — source QA¶
The prototype garage now requires an explicit second press of the same purchase shortcut within 8 real seconds before spending credits:
| Shortcut | First press | Second identical press |
|---|---|---|
| Q | Preview next locked car and its price | Attempt to unlock |
| U | Preview next engine level and its price | Attempt engine upgrade |
| I | Preview next grip level and its price | Attempt grip upgrade |
E still cycles between already-owned vehicles without spending credits. Insufficient funds, already-completed upgrades, locked career editing and unavailable cars never create a spend offer. If a menu is open, purchases can only be previewed and confirmed on its Garage page; shortcut keys cannot create invisible offers on a different menu page.
The on-screen garage feedback names the proposed purchase, the exact price and the matching key to press again. A different purchase, changed credits/ownership/tuning/selected car, invalid or backward clock, or expiry requires a fresh preview. Offers are in memory only, never persisted. Switching menu pages, opening/closing the menu, selecting another owned vehicle and race restart cancel the pending authorization.
Engineering safety¶
The portable GaragePurchaseConfirmation gate does not debit credits.
On the second press it authorizes only a single attempt to run the existing
GarageState::Unlock or GarageState::Upgrade. The game mode retains
its previous career-edit eligibility, price and funds checks, and
ProfileWriteCheckpoint rollback on save failure.
Time uses the platform monotonic clock rather than the paused Unreal world clock, so an open menu cannot extend the 8-second confirmation window indefinitely. This does not add financial purchases, microtransactions or online services; all credits are virtual in-game rewards.
Verification¶
python -m unittest discover -s Tests/Editor -p '*Tests.py'
cmake -S Tests/Standalone -B build/test
cmake --build build/test --parallel
ctest --test-dir build/test --output-on-failure
Portable GaragePurchaseConfirmation regression checks consumed
approvals, wrong key, changed balances and target, deadline, non-finite
clocks, insufficient credits and thousands of repeated sequences. Editor
source contract checks the ordering of authorization, existing garage
mutator, save and rollback.
Not a verified game build: UE 5.8 Editor/UHT, functional input feedback, gamepad/keyboard repeat behavior, SaveGame failure scenarios and an installed Windows playtest must still be tested. See playable qualification #148 and production UI milestone #236.
