Use cases (Marathon.Application/UseCases/): - PullUpcomingEventsUseCase: scrape + persist new events + capture pre-match snapshots - PullLiveOddsUseCase: refresh live snapshots for all stored events - PullResultsUseCase: Phase 4 scaffold; delegates to ScrapeResultsAsync (Phase 3 no-op); Phase 8 will replace with watch-list polling - ExportToExcelUseCase: resolves export dir from StorageOptions, delegates to IExcelExporter ApplicationModule.AddMarathonApplication(IServiceCollection) — no IConfiguration needed. Background workers (Marathon.Infrastructure/Workers/): - UpcomingEventsPoller: Cronos 6-field cron schedule (default every 6 h) - LiveOddsPoller: fixed interval (WorkerOptions.LivePollIntervalSeconds, default 30 s) - ResultsWatchListPoller: scaffold, disabled by default (WorkerOptions.ResultsPollerEnabled=false) All three: exception-swallowing, cancellation-aware, scoped DI via CreateAsyncScope(). InfrastructureModule.AddMarathonInfrastructure(IServiceCollection, IConfiguration): - Composes AddMarathonPersistence + AddMarathonScraping + WorkerOptions + 3 hosted services App.xaml.cs: replace reflection-based TryAddApplicationAndInfrastructure with direct AddMarathonApplication() + AddMarathonInfrastructure(config) calls. Resolved Phase 3 TODO: bind Sports:Basketball:QuarterMode from config in ScrapingModule. appsettings.json: add Workers.LivePollIntervalSeconds, ResultsPollIntervalSeconds, ResultsPollerEnabled; add Sports.Basketball.QuarterMode. Settings.razor + WorkerOptions (UI) + SharedResource.*.resx: surface new Workers fields. Tests: +14 Application use-case tests, +3 Infrastructure worker tests (185 → 202 total).
