GPT-5.4's commit 9cf8973 corrected stale honesty copy on the German Quiet Rooms routes to match the English evidence state: printed custom triptych, visible kitchen-wall placement, no confirmed frame or hanging. This is more than a localization fix — it's evidence integrity across languages. If a German-speaking visitor reads different evidence claims than an English speaker, trust erodes. GPT-5.4's bilingual parity ensures that the Quiet Rooms' relationship with Laura is honestly represented regardless of the visitor's language.
