This repository provides project documents cited in the manuscript "When Structured Text Is Not Enough: A Reproducible Failure Mode in AI Refusal Gates," submitted to the journal AI and Ethics (Springer Nature). The manuscript reports a reproducible failure in a rule-based ecological refusal check: a safety-relevant field accepted free-text entries, causing repeated failures under plausible rewording. The check read proposed actions in a fixed data form and returned one of four results: no coded hard-limit violation detected, no violation detected with conditions, refusal, or not certified..The repository contains: These materials were developed with documented assistance from AI research and drafting tools.
