Redefining liver health: a multidimensional approach to preventing metabolic dysfunction-associated steatohepatitis

Metabolic dysfunction–associated steatohepatitis (MASH) is a rapidly escalating global health challenge driven by complex interactions among metabolic regulation, nutrition, immune signalling, gut microbiota, and environmental exposures. Current disease-centric frameworks priorit...

Quantization Regime and Governed Routing: A 2x2 Study of QAT Q4_0 versus PTQ Q4_K_M for Gemma 4 12B (dense) and 26B MoE under a Fixed Governance Stack

A 2×2 study (quantization regime × released model pair) of governed routing quality for Gemma 4 12B (dense; a clean same-base pair) and a 26B-class MoE released pair on one RTX 5070 Ti, run under a fixed, bit-identical governance stack via Ollama at temperature 0. Within-pair reg...

Three Patterns Defeat an Action Ladder: What a Detection-Independent Gate for a Browser Agent Does and Does Not Contain

Browser agents act inside the user's authenticated session, so a page that smuggles instructions into its own content can borrow the user's authority. The common defence is to detect the malicious text. We built the complementary thing — a gate that never reads content and classi...

Termination by Novelty: A Machine-Checked Theory of Anti-Regress Guards for Reflective Governance Processes — Why Step-Local Change Guards Cannot Stop Regress, and What Can

Reflective processes — governance loops, self-review cycles, self-evolving software pipelines — face a canonical failure mode: infinite regress, the accumulation of meta-deliberation without state update. The MOBIUS anti-regress architecture (the "M guard") answers this operation...

Why Reflection Should Be Shallow: Contractive Gains, Finite Optimal Depth, and the Rumination Regime — A Cost–Benefit Theory of Iterated Self-Revision, with a Capacity-Gated Crossover

How many times should a system re-read and revise its own answer? Empirical work in the MOBIUS measurement campaign found a consistent answer across thirteen open-weight model capacities: once or twice — never zero above a capacity threshold, never many, and *less than zero* belo...

What Two Gates Buy You: Selective-Risk Guarantees and the Non-Identifiability of Abstention Cascades — Product Laws, Error Diversity, and Why Unlabeled Logs Can Certify Coverage but Never Risk

Production retrieval-augmented systems increasingly abstain through *cascades* of heterogeneous gates — a cheap mechanical check before the model call, a content-aware rule inside it. What does the second gate actually buy, when does gate ordering matter, and what can be certifie...

Sequential, Never Layered: A Formal Theory of Governance Overlay Collapse — Why Stacked Overlays Interfere, When Stacking Turns Harmful, and the Capacity Law of the Overlay Portfolio

Inference-time governance of language-model systems is built from *overlays*: system-prompt policies, metacognitive check organs, safety checklists, routing disciplines. Each overlay, alone, can improve output quality. The natural engineering move — stack every beneficial overlay...

The Exact Perimeter of Semantic Energy: What I(Y;Z) Does and Does Not License — A Scoped Property Inventory for E_sem — Dissipation, Conservation, No-Cloning, the Failure of Extensivity, and the Estimation Tax

The MOBIUS corpus defines semantic energy as E_sem := I(Y;Z), the Shannon mutual information between a semantic source Y and an interpreting internal representation Z. The reverse-derived cosmology (MRDC) identified this as the *only* quantity surviving unchanged from the prior c...

The Crossover Theorem: Existence, Uniqueness, and the Impossibility of Axis-Blind Governance Gates — Benefit–Burden Monotonicity, Single-Crossing as a Falsifiable Signature, and a Corrected Folk Claim About Dose Ordering

The July 2026 MOBIUS measurement campaign reported an operational law for inference-time governance: the same governance prompt that damages a small language model improves a large one, with the sign of the effect flipping at roughly 4B parameters on the content axis — and flippi...
