- Add IEventRepository/IResultRepository.GetManyAsync to kill N+1 lookups at 6 sites (backtest, outcome eval, both bet-journal paths, anomaly browsing, results selection); guarded by a Received(1).GetManyAsync test. - Add EventRepository.QueryAsync to push date+sport filtering to SQL (was load-whole-range-then-filter); search/sort stay in-memory for Cyrillic order. - Add AnomalyRepository.CountSinceAsync (unread badge) + ListByDateRangeAsync (feed date filter); add Event/Snapshot count methods for the dashboard. - Add composite indexes IX_Snapshots_EventCode_CapturedAt and _EventCode_Source_CapturedAt via a new migration + model snapshot. - Introduce SqliteDateText as the single source of the O-format date encoding shared by Mapping (read/write) and the repositories' range predicates. - Fix LiveOddsPoller cadence drift (budget sleep against cycle time); make DetectAnomalies dedup O(1) per event; add Event.Title to dedup the title join. Tests adapted to the batched GetManyAsync via a TestFixtures bridge.
