# Migration context

The current app intentionally does not migrate earlier Electrobun/Bun MVP data. `README.md` states that existing MVP data, Drizzle artifacts, Bun SQLite migrations, and Electrobun app-data layouts are not migration targets.

## Why it matters

This boundary lets the Rust core own a fresh SQLite schema in `crates/qa-scribe-core/src/storage/mod.rs`. It also keeps attachment storage and generation history aligned with current domain types under `crates/qa-scribe-core/src/domain`.

## Where to look

| File | Purpose |
| --- | --- |
| `README.md` | Current status and migration boundary. |
| `docs/adr/0009-rebuild-with-rust-tauri.md` | Rebuild decision. |
| `crates/qa-scribe-core/src/storage/mod.rs` | Fresh schema implementation. |
| `crates/qa-scribe-core/src/lib.rs` | App status declares `migration_required: false`. |

See [Rust core](systems--rust-core.md) for the implementation boundary.
