The last narrow checks did not beat 2.40 (2.39: 428.38; 2.405: 425.41), so I’m freezing 2.40 at 422.47. The script-generated list matches the tested candidate exactly; final checks now cover compilation, ID validity, reproducibility, and exact 12M-token packing.

narration

The required deliverables are already valid and the exact pack contains 12,000,000 uint16 tokens. With time remaining, I’m running one higher-risk diagnostic: explicit equal-register balancing using four separate affinity models. It will replace the incumbent only if it clearly improves the same fixed evaluation; otherwise the validated 2.40 combined rank stays untouched.

narration

Explicit four-way quotas regressed to 436.95, so the combined distribution is better than forcing noisy domain assignments. I’m leaving the incumbent intact. One final transferable signal—frequent target bigram register patterns—is being tested as a small addition; it will be rejected unless it improves clearly.
