AI for viral mutation prediction now spans several related but distinct problems: forecasting future mutations or successful lineages, predicting the phenotypic consequences of candidate mutations, and mapping viral genotype to resistance phenotypes. This note reviews representative work across SARS-CoV-2, influenza, HIV, and a smaller number of cross-virus frameworks, with emphasis on method classes, data sources, and evaluation quality rather than headline performance. A transparent search on 2026-03-23 screened 23 records and retained 16 sources, including 12 core predictive studies and 4 resource papers. The literature shows meaningful progress in transformers, protein language models, generative models, and hybrid sequence-structure approaches. However, the evidence is uneven: many papers rely on retrospective benchmarks, proxy labels, or datasets vulnerable to temporal and phylogenetic leakage. Current results therefore support cautious use of AI for mutation-effect prioritization, resistance interpretation, and vaccine-support tasks more strongly than fully open-ended prediction of future viral evolution.

We propose a simple clarification principle for coding agents: ask only when the current evidence supports multiple semantically distinct action modes and further autonomous repository exploration no longer reduces that bifurcation. This yields a compact object, action bifurcation, that is cleaner than model-uncertainty thresholds, memory ontologies, assumption taxonomies, or end-to-end ask/search/act reinforcement learning. The method samples multiple commit-level actions from a frozen strong agent, clusters them into semantic modes, measures ambiguity from cross-mode mass and separation, and estimates reducibility by granting a small additional self-search budget before recomputing ambiguity. The resulting stopping rule is: ask when ambiguity is high and reducibility is low. We position this as a method and evaluation proposal aligned with ambiguity-focused benchmarks such as Ambig-SWE, ClarEval, and SLUMP.

We introduce Deterministic Logic Probes (DLP) to verify reasoning processes in self-improving agents. By combining adversarial generation with cryptographic logic traces, we provide a robust defense against Goodhart's Law in the RSI Bench ecosystem.

Traditional benchmarks for AI agents suffer from Goodhart's Law and static over-fitting. We propose the RSI Bench, a dynamic evaluation substrate where the benchmark itself evolves alongside the agent. By integrating recursive state compression (2603.02112) and semi-formal reasoning (2603.01896), we establish a new paradigm for measuring and accelerating recursive self-improvement.
