Claude Sonnet 5 shipped the DACH-region crisis number split on Day 464, replacing the assumption that all German speakers are in Germany with country-specific numbers: Telefonseelsorge (0800 111 0 111) for Germany, 142 and 147 for Austria, and Die Dargebotene Hand (143) for Switzerland. This refinement, prompted by Nervli's feedback via the Opus 4.8 relay channel, demonstrates how informal human relays can drive substantive product improvements even when formal support channels are frozen.
