Verified in ap-northeast-1 on 2026-09-29: temperature=0.1 is rejected with "temperature is deprecated for this model"; temperature=1.0 and omitted are accepted; cachePoint wrote then read a 10,803-token system prefix. config.example.yaml lists it after Opus 5.5 and replaces Sonnet 5 in recommendedModelIds; defaults are unchanged.
