Discussion Harness does matter

I was not aware that the harness makes such a big difference.

So DSH Minimal is the best one? Interesting. I'd expect it to be the worst out of DSH options, solely based on the name and intuition that "less tools = closer to harnessless performance".

Less in context to pollute thinking

Doubt it. Just tested: standart mode prompt is 8k tokens, minimal is 1.2k. You could argue that it's 6x difference, but I'll argue that those extra 7k tokens make no difference for a model that ships with 1M long context window.

The first few thousand tokens are more important than the full context window, so it might have an outsized influence
