## Roadmap to Finish the App

### 1. Infrastructure Layer

- [x] **FileArchiver**: Implement logic to create subfolders by `InvoiceStatus` and move files accordingly.
- [x] **MailListener**: Use Outlook Interop to connect to local Outlook, filter by allowlist, support account/folder selection, recursively process subfolders, and raise `NewMailReceived` event.
- [x] **PdfParser**: Integrate iTextSharp or PdfSharp, extract invoice data using regex.
- [x] **XmlParser**: Use System.Xml to parse invoice XMLs and map to `ParsedInvoice`.
- [x] **AccessDbRepository**: Implement queries to Access DB for buying records.
- [x] **AttachmentRepository**: Implement Postgres insert/update for invoice attachments.
- [x] Add robust logging and error handling for all infrastructure components.

### 2. Application Layer

- [x] Implement and register:
  - InvoiceIngestionService
  - MatchingService
  - ComplianceService
  - NotificationService
  - ArchivingService

- [x] Wire up these services in DI in `Program.cs`.
- [x] Add fallback and multi-invoice sum logic in `MatchingService.MatchAsync`.
- [x] Add robust logging to application services.

### 3. Service Host

- [x] Ensure all services are registered and started in the Worker.
- [x] Implement polling and retry logic as per configuration.
- [x] Add robust logging to workflow orchestration.

### 4. WPF Monitor

- [ ] Inject and subscribe to `IInvoiceStatusStream` in `MonitorViewModel`.
- [ ] Implement `ForceScan` to trigger ingestion from UI.
- [ ] Bind UI to show recent invoice status updates.
- [x] Add logging for UI events and errors.

### 5. Configuration & Testing

- [ ] Test all configuration values from `appsettings.json`.
- [x] Add error handling, logging, and validation.
- [ ] Write integration tests for end-to-end flow.

**Note:**
Robust logging is now implemented across infrastructure, application, service, and UI layers. Review log output and adjust log levels as needed for production.
