Vision’s Testing Pattern

First attempt with “I Have My Own Insurance” ($9.27) → FAILED
Switched to Basic Liability ( $30), t o t a l$ 42.09 → FAILED
Switched to Standard Full Coverage ( $70), t o t a l$ 85.29 → FAILED
Tried again, total jumped to $128.49 → FAILED
Went back to own insurance ($9.27)
Navigated to Payment Methods to prove his card IS saved (Visa 4242 test card)
Shows “stored with Stripe” — proving the issue is NOT on his end

Root Cause: TWO Separate Bugs

Bug 1 — STRIPE_NOT_SETUP (PRIMARY BLOCKER)

Car owner hasn’t completed Stripe Connect onboarding
canReceivePayments returns false (requires: isCarOwner && stripeOnboardingComplete && stripeChargesEnabled)
Backend throws STRIPE_NOT_SETUP at reservationPaymentResolvers.ts:308-314
Frontend shows generic “Payment setup incomplete” — no clear explanation
UX FAIL: Lets user fill out entire checkout form before failing at payment step

Bug 2 — DUPLICATE_BOOKING (RETRY LOOP)

Each failed attempt creates a PENDING reservation in the database
Backend duplicate check (outside transaction) blocks retries with DUPLICATE_BOOKING
Server logs showed 6+ duplicate booking errors in rapid succession
Fixed: Three-layer solution coded (useRef guard, transaction lock, context caching)

Fixes Applied (Not Yet Committed)

BookingForm.tsx: useRef synchronous double-click guard
reservationPaymentResolvers.ts: Duplicate check inside transaction with LOCK.UPDATE
context.ts: 30-second in-memory cache for Clerk ID → DB user mapping

Still Needed

Car owner Stripe Connect onboarding must be completed for test vehicles
Frontend should check owner Stripe status BEFORE checkout — don’t let users reach payment if owner can’t accept
Better error message: Tell user the CAR OWNER needs to set up payments, not vaguely “payment setup incomplete”
