# RetrieX Patch p25 - Shop Context Fallback Cleanup Profile

## Goal
Wire the Shop context fallback/meta guard to the central `shop_context_fallback` cleanup profile from `language.yaml`.

## Scope
- Adds `shop_prompt.meta_query_guard.cleanup_profile: shop_context_fallback` to `config/retriex/agent.yaml`.
- Merges central profile stopwords, user-instruction phrases and presentation meta terms with the existing legacy meta/fallback lists.
- Keeps all legacy lists in place.
- Adds config validation for the referenced cleanup profile.

## Safety
No legacy lists are removed in this patch.
No Commerce, Retrieval scoring, Prompt wording, or shop matching logic is changed.
