The weak correct-path anchor is also neutral at 54.44%; it changes which problems improve, but not the aggregate. I’m testing a more targeted distributional idea next: teacher-support KL. Instead of matching all 151k vocabulary coordinates (mostly low-probability tail noise), it preserves the privileged teacher’s top support plus a single exact “other” mass bucket. This keeps a valid forward KL while focusing capacity on actionable teacher alternatives.
