narration

The 35% encyclopedia boundary test regresses to 328.37, chiefly by hurting technical Q&A, so the tested 30/25/23/22 allocation remains final. I’m retaining it and completing the last invariant checks on the overfilled tail.

The final artifacts are valid and reproduce the 318.43 result exactly. Since the remaining time safely exceeds delivery needs, I’m checking the two nearest allocation neighbors (28% and 32% encyclopedia); this is a narrow robustness search, not a redesign.

The neighboring allocations score 319.19 (28%) and 319.72 (32%), confirming the 30% encyclopedia point is locally best. I’ll do one final news-versus-technical split check while holding encyclopedia and web fixed.
