+# Rust CSV importer integration tested — matches Python DB exactly
+
+## Context
+
+The Rust CSV card importer (`api/importer.rs`) had unit tests for parse helpers but no integration test against real CSV data. The Rust DB previously had 0 cards because the importer had never been run against actual files.
+
+## Test Run
+
+1. Copied `BatterCalcs.csv` and `PitcherCalcs.csv` to `rust/docs/sheets_export/`
+2. Ran `import_all_cards()` against the Rust DB (`rust/data/sba_scout.db`)
+
+## Results
+
+| Type    | Cards Imported | Errors |
+|---------|---------------|--------|
+| Batter  | 490           | 0      |
+| Pitcher | 502           | 0      |
+
+Identical to Python DB row counts. Sample values verified (Rutschman batter card, Ben Brown pitcher card).
+
+## Committed
+
+CSVs committed to repo at `rust/docs/sheets_export/`.
+
+## Key Notes
+
+- Default CSV paths are relative to `rust/` cwd: `docs/sheets_export/BatterCalcs.csv` and `docs/sheets_export/PitcherCalcs.csv`
+- The Rust app uses `rust/data/sba_scout.db` (separate from Python's `data/sba_scout.db`)
