 - **`make:bridge:event <Name>` maker.** Generates a domain-event class (`src/Event/<Name>Event.php`, readonly value object), a subscriber (`src/EventSubscriber/<Name>Subscriber.php`) that republishes via `PublisherInterface` on `app://event/<kebab-name>`, and a QML stub (`{qml_path}/<Name>EventHandler.qml`) that listens via `MercureClient` and re-emits as a typed `signal`. Closes the third row of PLAN.md §8's makers table; pairs with the existing `make:bridge:resource` / `command` / `window` makers so domain events have a one-command path from PHP through to QML.
 - **`make:bridge:read-model <Name>` maker.** Generates a query-only projection: `src/ReadModel/<Name>ReadModel.php` (query service stub injecting `EntityManagerInterface`), `src/Controller/<Name>Controller.php` (single GET handler at `/api/<kebab-plural>`), and `{qml_path}/<Name>List.qml` (`ReactiveListModel` bound to the route, deliberately *no* Mercure topic — read-models aren't auto-reactive; invalidation is event-driven via `make:bridge:event`). Closes the fourth row of PLAN.md §8's makers table.
 - **Pre-migration auto-backup of `var/data.sqlite`.** Bundled-mode supervisor copies the SQLite file to `var/data.sqlite.<unix-timestamp>.bak` before invoking `doctrine:migrations:migrate`; trims to the 5 most recent. SQLite's lack of transactional DDL means a half-applied migration can corrupt the database with no rollback path; cheap insurance against that. Skipped on first launch (no DB to back up); failure to copy logs a warning and continues (a missing safety-net is not a reason to refuse to boot). Backup runs only in bundled mode — dev mode users own their `var/data.sqlite` lifecycle. Bundled-supervisor integration test gained an assertion that a `.bak` file appears under the user data dir on second launch.
+- **`bridge:export` console command + QML hook.** New `bin/console bridge:export <destination>` copies the active SQLite database to a user-chosen path (overwrites if the destination exists; reads the source path from `DATABASE_URL` so it works in both dev and bundled mode). Mirrored on the QML side as `BackendConnection.exportDatabase(path)` (`Q_INVOKABLE bool`) returning success synchronously and emitting `databaseExported(path)` / `databaseExportFailed(reason)` for async UX. QML callers typically pair it with `Qt.labs.platform.FileDialog` (see `docs/native-dialogs.md`). 4 unit tests cover the command's success / non-SQLite-URL / missing-source / overwrite paths.
