+# RetrieX Vocabulary Centralization Fix
+
+This patch centralizes the growing recognition word lists without changing their tuned content.
+
+## Main changes
+
+- Added `config/retriex/vocabulary.yaml`.
+- Added `App\Config\DomainVocabularyConfig`.
+- Wired the vocabulary facade into:
+  - `ShopServiceConfig`
+  - `NdjsonHybridRetrieverConfig`
+  - `PromptBuilderConfig`
+  - `CommerceQueryParserConfig`
+- Moved the active Shop and Retrieval vocabulary defaults out of `commerce.yaml` and `retrieval.yaml` into `vocabulary.yaml`.
+- Kept all old per-service config keys as explicit overrides.
+- Removed direct `NdjsonHybridRetrieverConfig::...` constant usage inside `NdjsonHybridRetriever` so effective config getters are used consistently.
+
+## Stability note
+
+The vocabulary views preserve the previous order and content of the tuned lists.
+No new semantic terms were added to the critical retrieval and shop matching views.
+
+Required regression baseline:
+
+- `Was ist der niedrigste Grenzwert für die Wasserhärte, welcher mit einem Testomaten überwacht werden kann?`
+  - expected: `0,02 °dH (Testomat 808)`
+- `mit welchem indikator wird der wert gemessen`
+  - expected: `Indikatortyp 300`
+- Store query with `0,02` must preserve the decimal value and must not turn it into `02`.
