Stage 8 — Smart Pricing Engine: contextual coefficients

Contextual multipliers layered on top of base MarkupRule pricing, applied per work-order line based on vehicle, client and urgency. Schema: - pricing_coefficients (multiplier, conditions JSON, priority, stackable) - vehicles.vehicle_class (sedan/suv/commercial/hybrid/ev/premium) - clients.is_vip - work_orders.urgency (normal/urgent/express) PricingEngine::quote(Part, Vehicle?, Client?, urgency): - base = MarkupRule on buy_price (fallback sell_price or buy×1.30) - context: class (explicit or inferred hybrid/ev from fuel), age, vip, urgency - stackable coefficients all multiply; non-stackable take only the highest - returns {base, final, applied[]} breakdown PricingCoefficient::matches(ctx) — classes/age range/vip/urgency conditions (empty = always applies). Filament: - PricingCoefficientResource with condition builder (classes, age, vip, urgency) - vehicle_class select, client is_vip toggle, WO urgency select - "Preț inteligent" action on WO parts shows breakdown + applies sell_price Tests (6 new): - base-only without coefficients; age coefficient gating; VIP; express urgency; stackable multiply vs non-stackable highest-wins; hybrid inferred from fuel Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
