Background

Enterprise systems, applied to AI assurance.

Decision-Space Integrity combines practical systems-engineering experience with research into decision-space collapse — the tendency of advisory AI outputs to make some plausible options visible while leaving others out. The framework grew out of a concern that a model response can be factually correct, safe, and helpful while still constraining the options a user can see and choose between.

"The future of AI isn't about replacing brilliance. It's about making brilliance more attainable." — Andrew J Cousins

Work

Research, software, and record.

Research

Decision-Space Collapse in Advisory Language Models — a preprint introducing decision-space collapse and the DSI measurement framework, with public replication materials.

Software

Decision-Space Integrity (DSI) — a self-hosted, stateless assurance tool that audits which configured expected paths are visible, missing, or recovered in AI model outputs. A v0.2 product candidate for evaluation and pilot.
