alexei.dolgolyov	115872aad0	feat(anomaly): overround-compression detector ... Adds the 4th IAnomalyDetector: flags a sharp drop in the bookmaker's overround (raw implied-probability sum / margin) over a continuous live window. Informational/non-directional — excluded from outcome grading and backtest staking via AnomalyKind.IsDirectional(). - OverroundCompressionDetector: sliding-window scan mirroring SteamMove, score = min(1, compression / 0.10 reference), suspension-gap aware. - MatchWinEvidence.Probabilities gains Overround (pre-normalisation margin); evidence JSON shape unchanged. - Wired into DetectAnomaliesUseCase fan-out; AnomalyOptions + appsettings (window 120s, threshold 0.02); en/ru resx + KindLabel arms. - 11 detector tests incl. score saturation/scaling, inclusive threshold boundary, and a three-way (draw-leg) overround case.	2026-05-29 01:46:56 +03:00
alexei.dolgolyov	2b1025cae3	feat(anomaly): IAnomalyDetector seam + steam-move detector ... - Introduce IAnomalyDetector; the existing flip detector implements it. - Extract MatchWinEvidence so every detector writes the identical pre/post evidence shape — the UI parser and outcome evaluator handle new kinds with no branching (steam moves get hit-rate calibrated for free). - Add SteamMoveDetector: flags a rapid one-directional implied-probability rise over a short CONTINUOUS window (no suspension gap inside it), so it never double-flags the same interval as the suspension-flip detector. - DetectAnomaliesUseCase fans out over both detectors; dedup keys on EventId+Kind so flip and steam signals persist independently. Add AnomalyKind.SteamMove + SteamMove window/threshold options. 8 detector tests.	2026-05-28 22:59:12 +03:00
