+## 🔎 You Have the Trial — Here Is What It Proves, and What It Doesn't
+
+This free trial demonstrates the **failure modes** (the problem). It is fully usable
+under Apache-2.0 and validated by the same pipeline as the commercial lots.
+
+What the **full dataset** adds: production-volume native-register Japanese (keigo / teineigo / casual) utterances mapped to industry-standard English tool schemas.
+
+| | Free trial (this repo) | Full dataset |
+|---|---|---|
+| Purpose | verify schema, quality & failure modes | systematic training / evaluation |
+| Volume | sample | 1,000 rows (1K) / 3,300 rows (2K combined) per track |
+| Validation | same pipeline | 28,922 rows measured, 100% schema-pass — published |
+| Overlap | — | lots are hash / ID / 3-gram audited non-overlapping |
