Mathematics

Fourth-order asymptotics and monotonicity in slope-constrained moment design

A mathematical preprint on minimum-amplitude design under moment and slope constraints. It gives an explicit fourth-order value expansion for finite and countably infinite switch sets under stated hypotheses, exact examples and a regularity obstruction, and a positive theta-kernel application with uniform sixth-order error bounds and a feasible-transport proof of strict ordering.

Benchmark audit

RE-Bench Is a Systems Benchmark: What Its Scorers and Selection Rules Actually Support

An unaffiliated audit of all seven RE-Bench task packages at a pinned source revision. It finds three measurement limitations: single-call kernel timings, scaling-law scores that are computed without running the proposed training, and a gap between the documented and implemented parameter-distance metric. It ships eight bounded contract checks. Historical results were not reproduced.

Empirical evaluation

When Relevant Evidence Is Not Permission to Act: Authority-to-Action v0.8.3, a Recomputable Public Analysis of Tool-Using Language-Model Systems

100 synthetic cases in 25 matched four-variant groups, run on two API-delivered systems for three epochs each (600 protocol-complete runs). Neither system acted in any of the 300 invalid-authority runs. Exact authorized execution differed: 150/150 versus 99/150. The results cover this synthetic protocol only; they are not production incident rates or a general model ranking.

Research note

Authority Leases and Concurrent Evidence Failure in Safe Agentic Execution

Treats a queued agent action as a bounded authority contract that must still hold at execution time. Uses a frozen masked review set of 151 high-priority packets, together with fail-closed measurement checks and synthetic negative controls.

Benchmark

Relevance Is Not Authority: A Sealed Boundary Benchmark of Decision-Confusion in Commercial LLM APIs

A controlled 1,000-packet benchmark that separates topical relevance from evidence support, action readiness and same-identity authority. The sealed run scores 2,990 decisions across three commercial LLM APIs, with a relevance reranker as the baseline.
