+# MathMentorDB sample (ungated)
+
+An ungated 50-conversation sample of the MathMentorDB labeled subset, provided
+so the data can be inspected without an access request. The full labeled
+subset (7,000 conversations, 165,275 messages, 24-move discourse labels and
+conversation resolution labels) is available gated under a Data Use Agreement
+at [mathmentordb/MathMentorDB](https://huggingface.co/datasets/mathmentordb/MathMentorDB),
+whose dataset card documents the schema, taxonomy, provenance, and ethics
+considerations. This sample uses the identical schema
+(`data/sample.jsonl`, one conversation per line).
