5. Removal of Global Tariff Matrix Fallback

Date: 2025-07-24

Status

Accepted

Context

Previous architecture used global settings as fallback for vehicles without matrices in price calculations. This caused hidden dependencies, performance issues, and unpredictable pricing.

Decision

Remove fallback to settings tariff matrices. Use only vehicle matrix for calculations. If no matrix on vehicle, perform calculations without any adjustments.

Consequences

Simplifies architecture, improves predictability and performance.
