narration

The first pass is CPU-bound because it is computing exact GPT-2 token counts and text statistics over hundreds of megabytes; it is progressing normally. Once cached, candidate changes and training comparisons will be fast. The initial profiling already suggests the cleaner half of the pool should dominate, but I’m allowing exceptional later documents to compete rather than imposing an arbitrary ID cutoff.
