 Flyer Crawler is a web application that uses the Google Gemini AI to extract, analyze, and manage data from grocery store flyers. Users can upload flyer images or PDFs, and the application will automatically identify items, prices, and sale dates, storing the structured data in a PostgreSQL database for historical analysis, price tracking, and personalized deal alerts.
 
-We are working on an app to help people save money, by finding good deals that are only advertized in store flyers/ads.  So, the primary purpose of the site is to make uploading flyers as easy as possible and as accurate as possible, and to store peoples needs, so sales can be matched to needs.

 **Robustness**: Eliminates an entire class of bugs where `undefined` is passed to `res.json()`, preventing incorrect `500` errors.
 **Consistency & Predictability**: All data-fetching methods now have a predictable contract. They either return the expected data or throw a specific, typed error.
 **Developer Experience**: Route handlers become simpler, cleaner, and easier to write correctly. The cognitive load on developers is reduced as they no longer need to remember to check for `undefined`.
-**Improved Testability**: Tests become more reliable and realistic. Mocks can now throw the *exact* error type (`new NotFoundError()`) that the real implementation would, ensuring tests accurately reflect the application's behavior.

For example, a service function that needs to update a user's points and create a budget in a single transaction cannot easily do so if both underlying repository methods create their own transactions.
 
 ## Decision
 
 We will implement a standardized "Unit of Work" pattern through a high-level `withTransaction` helper function. This function will abstract away the complexity of transaction management.
 
 1. **`withTransaction` Helper**: A new helper function, `withTransaction<T>(callback: (client: PoolClient) => Promise<T>): Promise<T>`, will be created. This function will be responsible for:
-
-* Acquiring a client from the database pool.
-* Starting a transaction (`BEGIN`).
-* Executing the `callback` function, passing the transactional client to it.
-* If the callback succeeds, it will `COMMIT` the transaction.
-* If the callback throws an error, it will `ROLLBACK` the transaction and re-throw the error.
-* In all cases, it will `RELEASE` the client back to the pool.

+   - If the callback throws an error, it will `ROLLBACK` the transaction and re-throw the error.
+   - In all cases, it will `RELEASE` the client back to the pool.
 
 2. **Repository Method Signature**: Repository methods that need to be part of a transaction will be updated to optionally accept a `PoolClient` in their constructor or as a method parameter. By default, they will use the global pool. When called from within a `withTransaction` block, they will be passed the transactional client.
 3. **Service Layer Orchestration**: Service-layer functions that orchestrate multi-step operations will use `withTransaction` to ensure atomicity. They will instantiate or call repository methods, providing them with the transactional client from the callback.

 1. **Adopt `zod` for Schema Definition**: We will use `zod` to define clear, type-safe schemas for the `params`, `query`, and `body` of each API request. `zod` provides powerful and declarative validation rules and automatically infers TypeScript types.
 
 2. **Create a Reusable Validation Middleware**: A generic `validateRequest(schema)` middleware will be created. This middleware will take a `zod` schema, parse the incoming request against it, and handle success and error cases.

-    * On validation failure, the middleware will call `next()` with a custom `ValidationError` containing a structured list of issues, which `ADR-001`'s `errorHandler` can then format into a user-friendly `400 Bad Request` response.
