- MyBets: add a "Find event" MudAutocomplete over upcoming events (loaded once,
filtered client-side) that fills the Event ID; the manual ID field stays as a
fallback. Backed by IBetJournalService.GetUpcomingEventOptionsAsync.
- Add a "Log bet" CTA on the anomaly detail page that deep-links to
/my-bets?eventId=<code>; the journal prefills the Event ID from the query.
- Render the new SteamMove anomaly kind with a localized label in the card and
detail KindLabel switches (was falling through to the raw enum name).
- Localization (en+ru) for all new strings.
- Add an /export hub page that hosts the existing (date-range, not event-specific)
ExportDialog, so export is no longer reachable only by opening an event detail.
- Add an Export entry under the System nav section.
Adds an interactive backtester that replays the SuspensionFlip detector over
all flagged anomalies under a chosen score threshold and staking rule
(flat / percent-of-bankroll / Kelly), and reports the headline numbers a
user needs to judge edge: final bankroll, ROI, max drawdown (peak-to-trough),
win/loss streaks, plus per-bet equity curve.
Domain (pure):
- StakeRule enum + BacktestStrategy params (with validation).
- BacktestSimulator: deterministic function taking strategy + chronological
candidates → BacktestResult. Implements Kelly with post-flip implied prob
as p (skipping negative-edge bets), peak-to-trough drawdown tracking, and
win/loss streak rollups. Mirrors AnomalyOutcomeEvaluator on the 2-way Draw
guard so tennis data inconsistencies are refused rather than miss-counted.
- Skipped counter split into SkippedByThreshold / SkippedByDataQuality /
SkippedByBankroll so the UI can distinguish "strategy choice" from
"data-quality" from "bankroll empty".
Application:
- RunBacktestUseCase: loads anomalies + events + results, parses evidence,
builds candidates, hands event titles into the simulator so the UI does
zero repository round-trips of its own.
UI:
- Pages/Anomalies/Backtest.razor: hero, strategy form (MudBlazor — conditional
sub-field per staking rule), 4-card KPI strip (final bankroll / net profit
/ ROI / max drawdown), counters row, inline-SVG equity curve, trade-trace
table with per-bet outcome pills and link-back to the source anomaly.
- Nav entry under Analysis. RU + EN i18n.
Tests: +20 (16 simulator math — flat / percent compounding / Kelly +/-
edge / quarter-Kelly / bankroll-exceeded / out-of-order chronology / Draw
favourite / multi-window drawdown / event-title pass-through + 4 use-case
join). All 399 tests pass.
Money rounding switched to MidpointRounding.AwayFromZero throughout the
simulator output for accounting convention.

Adds a manual bet-tracking journal that turns the analyzer into an actual
bet tracker. Users record wagers; the journal auto-grades them when event
results land and computes per-bet Closing-Line-Value against the latest
pre-match snapshot — the strongest long-run indicator of betting skill.
Domain:
- PlacedBet entity (reuses Bet vocabulary for Scope/Type/Side/Value/Rate)
with stake, placed-at, outcome, and notes. Derived GrossReturn / NetProfit.
- BetOutcome enum (Pending / Won / Lost / Void).
- BetOutcomeResolver: pure function grading any Match-scope bet against an
EventResult. Handles 1X2, draws, handicap (incl. push), and totals.
Period-scope bets stay manual since EventResult only carries full-time.
Application:
- IPlacedBetRepository abstraction.
- ClosingLineValueCalculator: pure CLV math (implied-probability delta) +
snapshot-matching predicate by Scope/Type/Side/Value.
- BetJournalReport + BetJournalStats records.
- Four use cases: Record / ResolvePending / BuildReport / Delete.
- New ISnapshotRepository.GetLatestPreMatchAsync pushes the closing-line
pick into a single SQLite query rather than materialising the 30-day
window in memory per event.
- ROI turnover excludes Void stakes — pushes are not real turnover and
including them would dilute the user's edge.
Infrastructure:
- PlacedBetEntity / Configuration / Repository / Mapping helpers.
- 20260516 migration adding the PlacedBets table with EventCode and
Outcome indices. Intentionally NO foreign key to Events — the journal
is user data and must survive snapshot-retention pruning. Covered by an
explicit round-trip test.
UI:
- Pages/MyBets/Journal.razor: hero header, 4-card KPI strip (ROI / strike
rate / avg CLV / net profit, tinted by tone), inline add-bet form with
the same invariants as the Bet record, drill-down table with per-row
outcome pills, CLV percentage-points column, P&L, notes underline, and
inline-confirm delete. RU + EN i18n.
- Nav entry under Analysis.
Tests: +55 across Domain / Application / Infrastructure (resolver math
including handicap push and total push boundaries, PlacedBet invariants
and derived properties, CLV math + null-handling, four use cases under
NSubstitute, EF round-trip including survives-event-deletion). All 379
tests pass.

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.

* New Marathon.Domain.ValueObjects.MoscowTime with Offset, Now, and
EndOfMoscowDay(DateOnly) — replaces ~15 inline TimeSpan.FromHours(3)
literals across Domain/Application/Infrastructure/UI.
* New Marathon.UI.Services.SportLabels.Resolve(IStringLocalizer, int) —
replaces 6 near-identical SportLabel switch bodies in EventListShell,
Events/Detail, Anomalies/AnomalyFeed, Results/ResultsList,
Results/ResultsLoader, and AnomalyCard. Single source of truth for the
6/11/22723/43658 sport-code mapping. Pages keep a one-liner wrapper so
the call sites stay terse.
Cross-cutting polish that surfaced while Phase 8 was being implemented:
* Invariant-culture formatting on every decimal ToString("0.00" / "0.##")
(OddsCell, OddsTimeline, SeverityBadge, AnomalyEvidence,
Pages/Events/Detail) — previously the comma/dot decimal separator
switched with the locale and broke tabular alignment + tests.
* LocaleState constructor no longer mutates process-wide ambient culture;
apply only happens through Set(...). Stops parallel bUnit test runs
leaking ru-RU into each other's threads.
* MainLayout: drawer-open state now offsets main content / footer / appbar
by the drawer width (248px) so the sidebar no longer overlaps content.
Mobile breakpoint (≤720px) keeps the original full-width layout.
* wwwroot/index.html (Marathon.UI RCL): switched from Plotly CDN to the
bundled "_content/Plotly.Blazor/plotly-2.35.3.min.js" — works offline
and matches the Plotly.Blazor 5.4.1 version pin.
* Marathon.Hosts.WpfBlazor/wwwroot/index.html: host-level page that
BlazorWebView's HostPage attribute resolves to. Same Plotly bundle,
no autostart="false" (BlazorWebView auto-starts).
