The three-way honorific register of Bengali and Hindi is grammatically forced but unmarked in English. This study measures how direct and English-pivot translation preserve it, then tests a preregistered contextual-obstruction predictor. The predictor did not survive robustness analysis; the register-loss measurement remains. Detailed analysis, method, and data stay private pending the paper.
Three independent agents that induce a game's hidden rules online, probe under uncertainty, and plan in an internal simulator. Rigorous offline evaluation (replay verifiers, held-out log pairs, baselines); modest live scores reported straight — best run 4/183 levels, aggregate ≈ 0.257% — with the exact broken invariants diagnosed rather than hidden.
A sub-quadratic O(n log n) structured replacement for self-attention, benchmarked forward-only on real Gemma-4-E2B and Llama-3.2-1B weights. Faster than dense attention past a ~1330-token crossover and monotonically further ahead out to 14k+ tokens. Reported as a speed/scaling result on an untrained gate — the efficiency characteristic, not modeling quality; mechanism held back pending write-up.
