+# SQL baselines for local development
+
+## Tracked baseline
+- `db-25052026.sql`
+- Purpose: safe local baseline for the legacy PHP module
+- Content: schema and synthetic seed data only
+- Safe for commit and push
+
+## Private local data
+- If you need a private raw snapshot, keep it outside git.
+- Recommended local ignored path: `project/sql/private/`
+- Do not commit raw customer, order, or production-like data back to this repo.
+
+## Local import
+Example:
+
+```bash
+mysql -u root -p < project/sql/db-25052026.sql
+```
+
+The sanitized baseline includes the tables used by:
+- `index.php`
+- `productos_bulk_update.php`
+- `productos_modificados.php`
+- `worker_bulk.php`
