+# RetrieX Patch 9.0a - PromptBuilder basis YAML-only
+
+This patch converts only the simple PromptBuilder basis, budget and shop-result limit values to required YAML configuration access.
+
+Changed file:
+
+- `src/Config/PromptBuilderConfig.php`
+
+Converted to required YAML-only access:
+
+- `budget.chars_per_token`
+- `budget.history_padding_chars`
+- `budget.output_reserve_ratio`
+- `budget.output_reserve_min_tokens`
+- `budget.output_reserve_max_tokens`
+- `budget.safety_reserve_ratio`
+- `budget.safety_reserve_min_tokens`
+- `budget.safety_reserve_max_tokens`
+- `budget.min_prompt_budget_tokens`
+- `shop_results.max_results_in_prompt`
+- `shop_results.detailed_max_count`
+- `technical_product_keyword_match_threshold`
+
+No prompt wording rules, fact-grounding rules, retrieval logic, shop logic, AgentRunner logic, or SSE/frontend code is changed.
+
+After applying, run:
+
+```bash
+php bin/console cache:clear
+php bin/console mto:agent:config:validate
+php bin/console mto:agent:config:audit-source --details
+php bin/console mto:agent:regression:test
+```
