The news-heavy mix regressed to 350.4, and pushing encyclopedic data to 40% regressed to 359.5. The best observed allocation is therefore the interior one-third / two-ninths split at 343.7. I’ll do one nearby 30% check to ensure that gain is not a noisy boundary effect, then freeze the best and build the final reproducible script and validity checks.

The 30% neighbor regressed to 359.3, confirming the one-third encyclopedic mix as the clear local optimum. I’ve frozen that criterion into the deliverable script; I’m now running it end-to-end from raw inputs, then I’ll compare its output byte-for-byte with the tested 343.7 candidate and perform the official pack/ID validity checks.
