- 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.
