narration

The full dev run exposed an important falsification: the first heuristic scored 512.9 perplexity versus 476.7 for random. Its “lexical richness” reward was selecting uncommon vocabulary that a 30M model cannot amortize under 12M tokens. I’m discarding that candidate and revising the observable: reward target-like function-word rate and sentence structure, while treating vocabulary extremes as a penalty rather than a benefit.

narration

The revised extreme rank improved to 496.0 but still trails random. That confirms the main failure is over-concentration, not just the richness term. The next candidate keeps the crawl’s natural domain coverage and applies only conservative rejection filters; accepted documents are ordered by a stable content hash, which should improve cleanliness without shrinking topical entropy.
