# RetrieX Product Role Guard Fix

This patch tightens answer behavior for product-selection questions where the user asks for a main device, Testomat, analyzer, measuring device, system, or similar product role.

## Goal

If the user asks for a main device:

- accessories, indicators, reagents, spare parts, kits, sets, services and consumables must not be used as the main answer heading;
- if only accessory/consumable hits are present, the answer must start with a no-match statement for the requested main device;
- incompatible accessory records are marked as such in the prompt and their commercial fields are suppressed;
- alternative devices must not be suggested unless suitability is explicitly proven in the provided sources.

The patch does not change retrieval, scoring, Shopware search, SSE, job lifecycle, or AgentRunner orchestration.
