- 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)
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.
Anonymous scraping confirmed feasible for marathonbet.by — site is fully SSR
(nginx), no Cloudflare or JS challenge. HttpClient + AngleSharp + Polly v8 is
sufficient; Playwright not required (kept as a future-flag).
Spike outputs:
- spike/SCRAPE_FINDINGS.md — page rendering, URL templates, anti-bot, rate
limits, recommended scraping strategy for Phase 3.
- spike/SCHEMA_DRAFT.md — customer-spec field → DOM selector mapping for
Match + Period-N scope across football/basketball/tennis (hockey TBD).
Phase 1+ handoff captured in subplan + CLAUDE.md. Critical Phase 8 finding:
no public results endpoint at /su/results — phase 8 must switch to polling
event-detail until eventJsonInfo.matchIsComplete=true (deviation flagged).
Reviewer notes addressed:
- Period market outcome codes corrected to RN_H/RN_D/RN_A (not 1/draw/3) and
market name vocabulary clarified per-sport in SCHEMA_DRAFT §3.1.
- results-page.html capture added to file list with caveat about live-landing
score-state and unsampled hockey selectors.
