Adds a "By detector kind" breakdown to the anomaly outcome report + Insights page,
answering "which directional detector actually wins?". Only directional kinds
(SuspensionFlip, SteamMove) resolve to hit/miss, so the breakdown naturally shows
just those — mirrors the existing by-sport / by-severity bucketers and rendering.
- AnomalyOutcomeReport.ByKind + EvaluateAnomalyOutcomesUseCase.BuildKindBuckets
(keyed OutcomeBucketKeys.KindPrefix + enum name); threaded through the insights VM/service.
- Insights page: new section + BucketRenderKind.Kind label case (resolves the enum name
to the Anomaly.Kind.* resx); en/ru section heading.
- 2 tests: empty-report ByKind + directional-kind grouping.
Adds a calibration dashboard that joins persisted SuspensionFlip anomalies
with EventResult rows and reports whether the post-flip favourite actually
won — the single metric that says whether the detector is doing its job.
Domain:
- AnomalyEvidenceData + AnomalyEvidenceParser to read the JSON written by
AnomalyDetector without re-implementing the schema.
- AnomalyOutcomeEvaluator: pure function returning Hit / Miss / Unresolved.
Tennis-style two-way markets with a Draw winner are downgraded to
Unresolved rather than silently counted as Miss.
- AnomalySeverityThresholds: shared Low/Medium/High constants so the UI
badge and the report buckets cannot drift.
Application:
- EvaluateAnomalyOutcomesUseCase orchestrates the join + aggregation.
- AnomalyOutcomeReport carries totals, hit rate, three breakdowns
(severity / sport / score bins) and a per-event title lookup so the UI
needs no second pass over IEventRepository.
- Score bins extend below 0.30 automatically when the operator lowers the
detector threshold so the histogram total always equals ResolvedCount.
UI:
- Insights page at /anomalies/insights — hero header, 4-card KPI strip
(hit rate tinted by tone), three breakdown grids with bar visualisation,
drill-down tables for resolved and unresolved anomalies. Honors
prefers-reduced-motion. RU + EN localisation.
- Nav entry under Analysis section + chip button on the Anomaly Feed.
Tests: +42 across Domain + Application (evaluator boundary cases including
tennis two-way and Draw guard, score-bin edges, dynamic floor when
threshold is lowered, event-title pass-through). All 324 tests pass.
