Why Fisher's exact test is least exact where it matters most: achieved size, wasted power, and a routing rule for 2x2 tables -- m02d Reproducibility deposit

Why Fisher's exact test is least exact where it matters most: achieved size, wasted power, and a routing rule for 2×2 tables William J. Dwyer, MD, MPH, FAAP — Department of Mathematics and Statistics, University of Massachusetts Lowell. ORCID 0009-0004-0855-7222. Concept DOI (always resolves to the latest version): 10....

C2Cognitive Core: Evidence-Bounded Persistent Cognition for AI Coding Agents

Persistent cognition changes the assurance requirements of AI coding agents because durable memories, lessons, reusable skills, structural observations, and derived knowledge can influence later engineering work after repository state, task context, or execution sessions have changed. C2Cognitive Core v1.0.0 presents a...

ninadphalak/LLM-Shield-Proxy: v1.3.0: Stateless Cryptography, MCP Governance, Air-Gapped Egress, and System Hardening

LLM-Shield-Proxy v1.3.6 delivers a comprehensive plain-language documentation rewrite, dead-guard removal, security policy unification, and Vault encryption key fixes. Highlights: Plain-Language Documentation: Comprehensive rewrite of public documentation, website guides, landing page copy, and benchmark reports for cl...

It's not easy being green: embedding environmental sustainability in training material

UKRI is committed to reaching Net Zero by 2040 and RSE/DRI will be key to achieving this. Green software practices will play a crucial role in this transition and so are increasingly discussed in the community - in part thanks to the Green RSE Special Interest Group. For full adoption, we must enable the next generatio...

CT-PPO Experimental Artifacts for Multi-Tenant ISAC Sensing-Session Consolidation

Experimental artifacts supporting the manuscript “Sense Once, Serve Many: Common-Trace Factorized Constrained PPO for Online Sensing-Session Consolidation in Multi-Tenant ISAC Networks.” This deposit contains the final artifacts used for the learned-policy comparisons, component ablation, arrival-load robustness evalua...

The Intent Bottleneck: When AI Compresses Delivery, Strategy Becomes the Constraint

This working paper argues that AI-native delivery compresses only the final stage of a six-stage chain running from an institution's covenant with those it serves to running software, so that by Amdahl's law the constraint moves upstream into how organisations form, prioritise, and preserve intent. It introduces intent...

C2GRAPH: A Repository-Level Governance Package for Disciplined, Measurable AI Coding Agents

AI coding agents increasingly operate as long-horizon software actors: they inspect mutable repositories, call tools, preserve state across interruptions, and may eventually modify artifacts whose failure modes are difficult to reverse. This paper presents C2GRAPH (Convert to Graph Engineering), a repository-side gover...

(Over)Reliance on Test Agents in AI-Assisted Software Testing

citation-cliques: Replication package for Citation-Network Cohesion Across Journal-Impact Strata

Version 4 contains the verified full-cohort replication workflow, tests, manuscript sources, generated aggregate results, and compiled PDFs for Citation-Network Cohesion Across Journal-Impact Strata. The canonical rebuild uses every eligible identified author in the fixed source snapshot and produces 102,626 matched pa...

Active Inference and Digital Twins for dynamic reconfiguration of software systems

In the following, the artefacts used during the experiments described in the article titled "Active Inference and Digital Twins for dynamic reconfiguration of software systems" are provided. The experiments were designed to evaluate and compare a Digital Twin enhanced with Active Inference (AIF-enhanced DT) proposal wi...

PyFgsea: GSEA in Python and Rust

PyFgsea 0.2.0 Release date: 2026-09-02. PyFgsea 0.2.0 updates the statistical core used by the high-level Python API and narrows the trajectory interface to functions that are implemented and tested. The paper remains reproducible with its original software pair; current comparisons use a separate, newer reference pair...

A Unified Taxonomy of Modeling Paradigms: Linear, Nonlinear, Context-Variable, and Self-Directed Causal Frameworks with Theoretical Foundations and Empirical Validation

This manuscript develops a unified taxonomy for modeling paradigms in complex, non-stationary systems, organizing linear, nonlinear, context-variable (regime-switching), and self-directed causal frameworks under a single structural causal model (SCM) formalism. Building on Markov-switching structural vector autoregress...
