KV quantization still found facts in a 100k context

KV quantization at q4_0 still found the right information inside a long input. The test used a 100k context, and the answer matched the inserted information. The draft model also used q4_0 for its KV data.

The first example involved Harry Potter, so others pointed out that the answer might have come from training data rather than the long input. A follow-up used a less common line from an Italian 2026 book to reduce that concern.
