+# RetrieX Patch 26 - Language Cleanup YAML Dedup
+
+Purpose: simplify the maintenance layer after p21-p25.
+
+Changes:
+
+- Removes duplicate generic language noise from legacy Commerce/Agent lists when the terms are already supplied by `language.yaml` cleanup profiles.
+- Keeps all domain-specific, commerce-specific and regression-sensitive tokens in their original domain configs.
+- Adds comments that mark remaining lists as legacy/domain override lists.
+- Does not change profile names, service wiring, routing or retrieval logic.
+
+Guardrails:
+
+- Do not move protected terms into generic removal logic.
+- Keep intent/domain terms in their domain YAML files.
+- Only remove a legacy term when it is covered by an active cleanup profile or clearly duplicated in the same list.
+
+Required checks:
+
+```bash
+bin/console mto:agent:config:validate
+bin/console mto:agent:regression:test
+bin/console mto:agent:config:audit-source --details
+bin/console mto:agent:config:audit-patterns --details
