narration

The conservative target-affinity rank is a clear improvement: dev perplexity fell from 466.03 to 453.35. Its selected examples span wire news, Wikipedia-like biographies, government/reference prose, and technical material, which matches the intended mechanism. I’m tuning only the affinity strength now and will retain the best measured setting.

narration

Increasing affinity strength improved again, though gains are flattening: 440.41 at weight 0.8 and 439.92 at 1.5. The rank prior still confines consumed data to the clean early portion of the pool; I’m testing the nearby stronger setting to locate the turn before target affinity starts admitting lower-quality pages.
