+# 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.
