+# weft-script-lineage — synthetic training data + negative-result evidence
+
+Companion data for the model [wallfacers/weft-lineage-extractor-1.5b](https://huggingface.co/wallfacers/weft-lineage-extractor-1.5b),
+a **research artifact** demonstrating that synthetic-only training induces a **memorization
+leak** in small models for ETL table-lineage extraction.
+
+## Contents
+
+- `train.jsonl` / `heldout.jsonl` — 10,000 + 600 **synthetic** ETL scripts with table-lineage
+  labels (Python/Shell). `out-jvm/` adds the Scala/Java-augmented variant.
+- `reports/` — the frozen evaluation evidence:
+  - `eval-report-v2.md` — synthetic held-out (near-perfect, the misleading number).
+  - `eval-real.md` / `eval-real-jvm.md` — four-way comparison on **real** GitHub scripts.
+  - `leak-report.md` / `leak-report-jvm.md` — memorization-leak quantification.
+  - `leak-curve.md` — leak vs. model scale (0.5B/1.5B/3B).
+  - `paper-negative-result-findings.md` — the full write-up.
+  - `ADJUDICATION.md` — the human-gold labeling convention (Convention A) + provenance.
+
+## Note on real scripts
+
+The **real-evaluation gold** (`realeval/gold/*.jsonl`) contains third-party GitHub script
+content and is **not** included here by default (license/redistribution care). It is uploaded
+only when the publisher passes `--include-real-gold` after license review.
