Instead of a single optimizer processing all experience, EvolveNet distributes harness evolution to local agent deployments. This allows each deployment to adapt the harness to its specific workload, and then these localized adaptations are composed to create a more robust and universally improved harness.

This paper introduces Recoverability-Aware Intervention Learning (RAIL), a framework that optimizes how reinforcement learning policies learn from rollouts. Instead of uniform rollout allocation, RAIL dynamically selects and intervenes in rollouts based on their predicted learning improvement, treating it as an online contextual-bandit problem.

The core method involves an LLM-based optimizer iteratively improving a given harness based on graded feedback and a fixed evaluation budget, aiming to maximize performance gains over an initial seed harness. The key contribution is providing a standardized protocol for measuring this crucial, yet previously unquantified, capability of LLMs in agentic systems.

This paper highlights a critical "retrieval-integration gap" in AI financial research: LLMs can accurately retrieve information from long financial documents, but this retrieved data doesn't reliably influence their investment judgments. The core contribution is demonstrating that even with accurate retrieval, the sheer volume of unrelated context can drown out the impact of crucial disclosures, leading to flawed decisions. The authors propose that workflow design, specifically how information is compressed and linked to sources, is key to bridging this gap and enabling AI to truly "use" financial information.
