Snapshot of the parallel batch (Phases 2 + 3 + 5) at session pause. Solution does
NOT build cleanly yet — known cross-phase compile issues remain to be resolved
before review. See plans/initial-implementation/PLAN.md "Resume Notes" section
for the exact tomorrow-morning action list.
Phase 2 (Storage):
- Repository interfaces in Marathon.Application/Abstractions
- DateRange, ExportKind, StorageOptions in Marathon.Application/Storage
- EF Core 8 + SQLite (WAL) persistence: 7 entities + configurations + 4 repos
- Hand-written InitialCreate migration (dotnet ef blocked by parallel work)
- ClosedXML ExcelExporter with exact customer-spec wide columns
- PersistenceModule.AddMarathonPersistence DI extension
- Round-trip + export tests (cannot run yet — see cross-phase issues)
Phase 3 (Scraping):
- IOddsScraper, IBetPlacer in Marathon.Application/Abstractions
- ScrapingOptions in Marathon.Infrastructure/Configuration
- MarathonbetScraper with 4 parsers (Upcoming, Live, EventOdds, Results)
- Helpers: ServerTimeProvider, PeriodScopeMapper, OutcomeCodeMapper, MoscowDateParser
- UserAgentRotatorHandler + Polly v8 resilience pipeline
- ScrapingModule.AddMarathonScraping DI extension
- GlobalUsings.cs aliases for EventId / Configuration disambiguation
- Parser tests with trimmed HTML fixtures
- ScrapeResultsAsync interim no-op (Phase 8 will replace via watch-list polling)
Phase 5 (UI shell — killed mid-final-verify, assumed ~95%):
- Marathon.UI populated: MainLayout, App.razor, Pages (Home, Settings),
Components, Theme (MarathonTheme.cs + Tokens.cs + app.css), Resources
(SharedResource.{cs,ru.resx,en.resx}), Services (ISettingsWriter), wwwroot
- WPF host: App.xaml(.cs), MainWindow.xaml(.cs), Marathon.Hosts.WpfBlazor.csproj
with Microsoft.AspNetCore.Components.WebView.Wpf + MudBlazor + Serilog
- appsettings.json + appsettings.Development.json with all sections wired
- bUnit tests: MainLayoutTests, LocaleSwitcherTests, ThemeToggleTests,
JsonSettingsWriterTests + Support helpers
Cross-phase issues to resolve at next session:
1. Phase 2 repository classes are 'internal' — Phase 3's tests can't reference
them. Fix: add InternalsVisibleTo to Marathon.Infrastructure.csproj.
2. Phase 5: LocalizationOptions namespace ambiguity (AspNetCore vs Extensions).
3. Phase 5: WpfBlazor Serilog API mismatch.
Reviewer has NOT run on this batch. Move to Phase 4 only after build is green
and a combined parallel-batch reviewer passes.
maraphon-app
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

Build & run
dotnet build Marathon.sln
dotnet test Marathon.sln
dotnet run --project src/Marathon.Hosts.WpfBlazor
Configuration
All variable parameters (polling intervals, concurrency, user-agents, retry policy,
snapshot retention, locale) are exposed via appsettings.json and live-editable via
the in-app Settings page.
Status
🟡 In active development. See plans/initial-implementation/PLAN.md
