# SBA Scout Rust: two separate databases for Rust vs Python apps

## Decision

The Rust rewrite maintains its own independent SQLite database, separate from the Python app.

| App    | DB Path                        | Size (approx)     |
|--------|-------------------------------|-------------------|
| Python | `data/sba_scout.db`           | 1.7 MB (full)     |
| Rust   | `rust/data/sba_scout.db`      | 491 KB (initial, grows after import) |

Both paths are relative to the repo root. The Rust app's `config.rs` defaults `db_path` to `data/sba_scout.db` relative to `cwd`, which resolves to `rust/data/sba_scout.db` when running from the `rust/` directory.

## CSV Import Paths (Rust)

Default paths (relative to `rust/` cwd):
- `docs/sheets_export/BatterCalcs.csv`
- `docs/sheets_export/PitcherCalcs.csv`

## Rationale

The Rust rewrite is being developed on a separate branch (`feat/rust-rewrite`) and needs its own DB so development and testing don't interfere with the production Python app data.
