alexei.dolgolyov a6ff368015 feat(phase-7-backend): implement anomaly detection — SuspensionFlip detector, use case, poller, and tests 
- AnomalyDetector (pure domain): detects odds-flip pattern from live snapshot
  timelines using implied-probability vectors (p=1/rate, normalised), flip score
  = max(|p_post−p_pre|), gated by both threshold AND favourite-changed test
- SuspensionInterval record: typed pair of (pre, post) OddsSnapshot bracketing a gap
- AnomalyOptions POCO (Application layer): bound to Anomaly:* config section with
  four fields (SuspensionGapSeconds=60, OddsFlipThreshold=0.30, MinSnapshotCount=3,
  DetectionIntervalSeconds=60)
- DetectAnomaliesUseCase: iterates all events, loads last-24h live snapshots, runs
  detector, persists new anomalies with 1-minute dedup window
- AnomalyDetectionPoller: BackgroundService polling every DetectionIntervalSeconds,
  gated by WorkerOptions.AnomalyDetectionEnabled (default true)
- DI wiring: DetectAnomaliesUseCase registered Scoped in ApplicationModule;
  AnomalyOptions bound + AnomalyDetectionPoller hosted in InfrastructureModule
- WorkerOptions.AnomalyDetectionEnabled added; appsettings.json updated
- 13 domain tests + 4 application tests; total 245/245 passing (no regression)

alexei.dolgolyov 2acbaa5b77 feat(phase-4): application layer + background workers — 202/202 tests green 
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).

alexei.dolgolyov 61114ea31b feat: implement Phase 1 — solution skeleton and domain model 
Creates the 9-project .NET 8 solution (5 src + 4 test) with Marathon.Domain
fully implemented: value objects (SportCode, EventId, OddsRate, OddsValue,
BetScope hierarchy), enums (Side, BetType, OddsSource, AnomalyKind), and
entities (Sport, Country, League, Event, Bet, OddsSnapshot, EventResult,
Anomaly) with all invariants enforced in constructors. 96 domain tests pass
(FluentAssertions + xUnit). Directory.Build.props and Directory.Packages.props
centralise build settings and NuGet versions. Both Marathon.sln and Marathon.slnx
are committed; dotnet build Marathon.sln succeeds with 0 warnings/errors.
