# 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:

bin/console mto:agent:config:validate
