Review follow-ups: - (HIGH) Add real-SQLite round-trip tests for the new query methods so the load-bearing lexical O-format date ordering is verified, not just mocked: Anomaly ListByDateRange/CountSince, Snapshot CountSince/ListByEvents grouping, Event Query/GetMany. - (MED) DetectAnomaliesUseCase: one SaveChanges per event instead of per anomaly. - (LOW) Route PlacedBetRepository + ExcelExporter date bounds through SqliteDateText. - (LOW) Backtest: reject a one-sided date range (was silently ignored). - (LOW) Refresh stale comments after the detector fan-out.

Sports betting odds analyzer for marathonbet.by.
Scrapes pre-match (/su) and live (/su/live) sports events, tracks coefficient changes
over time, and detects anomalies — in particular the "odds-flip" pattern where the
bookmaker freezes betting and then inverts underdog/favorite odds.
Tech stack
- .NET 8 + C# 12
- Blazor Hybrid — WPF shell hosting
BlazorWebView(designed to migrate to ASP.NET Core Blazor Server with no UI rewrite) - EF Core + SQLite (WAL mode) for local storage
- ClosedXML for Excel export
- AngleSharp for HTML scraping (with Playwright fallback for JS-rendered pages)
- Polly v8 for retry / circuit breaker / rate limiting
- MudBlazor UI components, Plotly.Blazor for charts
- Serilog structured logging
- xUnit / FluentAssertions / NSubstitute for tests
