Hierarchical Online Prompt Mutation with Dual-Loop Feedback for Guardrailed Evidence Document Generation: A Production-Evaluation Case Study

arXiv:2606.01472v1 Announce Type: cross Abstract: High-stakes production document-generation systems require language models to be adaptive, evidence-grounded, and auditable. We present HOPM, a hierarchical online prompt mutation framework evaluated on a real marketplace dispute-evidence workflow. HOPM treats prompts as online policies: a family/version router selects a prompt, deterministic guardrails attribute failures to mutable prompt-token categories, and dual feedback from human review and an automated judge updates both routing and mutation priorities. The primary evidence is an observe

Why this matters
Why now

The increasing deployment of large language models in high-stakes environments necessitates robust guardrails and adaptive systems capable of real-time learning and auditing.

Why it’s important

This research outlines a practical framework for deploying adaptive and auditable AI in critical applications, addressing core concerns about reliability and control in real-world use cases.

What changes

The focus on 'Hierarchical Online Prompt Mutation' and 'Dual-Loop Feedback' signifies a move towards more dynamic, self-correcting, and explainable AI in production systems, crucial for trust and widespread adoption.
