# RetrieX Prompt Config Centralization Fix

This patch centralizes PromptBuilder wording and label configuration in `config/retriex/prompt.yaml` while keeping the previous PHP defaults as fallbacks.

Changed files:

- `config/retriex/prompt.yaml`
- `src/Config/PromptBuilderConfig.php`

Scope:

- Section labels
- Conversation context intro lines
- Live shop result prompt rules
- Output priority rules
- Response format rules
- Language rules
- Fact grounding rules
- Retrieved knowledge / URL source labels
- Shop result field labels
- Technical product model pattern

Intentionally unchanged:

- Main active system prompt from the database
- Retrieval logic
- Shop search logic
- Vocabulary / intent / agent config logic
- PromptBuilderConfig keyword detection, which remains backed by `vocabulary.yaml`

After applying:

1. Clear Symfony cache.
2. Run the known 1.4.2 regression prompts.
3. Verify that generated prompt sections remain identical to the previous behavior.
