# Chain Break Audit (v0.1)

A micro-benchmark for brittle reasoning in multi-step tasks.

Instead of scoring correctness, this dataset measures **where and how reasoning collapses** — revealing weak spots invisible to standard accuracy or hallucination metrics.

## What It Tests

- skipped logical steps  
- invented transitions  
- authority substitution  
- premature final answers  
- merging distinct operations  

These failure modes highlight **structural instability**, not just factual errors.
