# Self-heal SQL: database-disjoint Spider splits

Splits and SQLite databases used for a self-healing text-to-SQL agent
(detect failures -> classify -> generate corrective examples -> DPO retrain -> gate).

Derived from **Spider** (Yu et al., 2018, https://yale-lily.github.io/spider), CC BY-SA 4.0.

| split | source | purpose |
|---|---|---|
| `pool` | Spider train, DB group A | failure pool; its failures become training data |
| `gate` | Spider train, DB group B | held-out deployment gate; never used to build training data |
| `test` | Spider dev | headline before/after numbers |

No database appears in more than one split (asserted at build time). Rows whose gold query
errors, times out or returns zero rows were dropped.

Row fields: `qid, split, db_id, question, gold_sql, db_path, schema`.
`db_path` is relative to the repo root.
