[Performance] Claude 3.5 Opus regression: Reduced problem-solving capability compared to previous versions

Bug Description
this conversation shows how badly Opus 4.7 operates vs 4.6 - 4.7 has been severely crippled in its ability to find solutions itself - most probably because of optimizations i suspect. (not a specific error)
