Asymmetric Repository Lineage Modeling and Verifier-Guided Coordination in Concurrent AI Coding Agents
Arjun Subramanian, George Xu, Nithilan Karthik
Concurrent AI coding agents create a coordination problem in which cheap signals may prioritize work, but only an executable checker can establish the property being claimed. We st…
Repeated-Measure Leakage, Distribution Shift, and Reliability under Partial Observation in Patient World Models
Arjun Subramanian
Patient world models are increasingly proposed for longitudinal prediction, intervention-aware reasoning, and clinical-trial simulation. Causal or clinical intervention validity is…
Counterfactual Action Evaluation, Observation Bottlenecks, and Representation Geometry in Joint-Embedding Predictive World Models
Arjun Subramanian
Low latent prediction error does not establish that a world model distinguishes the consequences of its actions. We introduce an evaluation protocol that traces the same interventi…
AI Agent Pull Requests on GitHub: Frequency, Structure, and Merge Conflict Rates
George Xu, Arjun Subramanian, Nithilan Karthik
AI coding agents may generate and submit Pull Requests (PRs) to the same repository at the same time. However, research concerning the extent of concurrent submission by AI coding…
