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.

Implements Phase 8 Amendment 1: marathonbet.by has no public results archive
endpoint, so results must be harvested per-event by re-fetching the event
detail page until eventJsonInfo.matchIsComplete=true.
Backend changes:
* IOddsScraper:
- ScrapeResultsAsync(DateRange) replaced with ScrapeEventResultAsync(Event)
returning a nullable EventResult — null when match still in progress.
- ScrapeEventOddsAsync now takes the full Event (so EventPath drives URL
construction) instead of bare EventId.
- New ScrapeLiveAsync() for the /su/live listing.
* Domain:
- Event gains EventPath (nullable string) — the data-event-path attribute
captured during scraping; required for reliable URL construction.
* Infrastructure:
- New migration 20260506000000_AddEventPath adds the column.
- EventEntity / EventConfiguration / Mapping / model-snapshot updated.
- MarathonbetScraper: new ScrapeLiveAsync + ScrapeEventResultAsync; URL
builder prefers EventPath, falls back to numeric ID for legacy rows.
- EventListingParserBase extracts data-event-path on every listing row.
* Application:
- PullResultsUseCase: branches on selection vs date-range, emits IProgress<
PullResultsProgress>, returns ResultLoadOutcome (Loaded / AlreadyLoaded /
NotYetComplete / Failed); idempotent (skips events whose result already
exists).
- PullLiveOddsUseCase now drives off the live listing (auto-discovers
events that go live without ever appearing in the upcoming list) and
backfills EventPath on legacy rows.
- PullUpcomingEventsUseCase wires EventPath on persisted events.
* Workers: UpcomingEventsPoller updates persistence path accordingly.
* Tests: 17 net-new tests across Application + Infrastructure + Domain;
all 293 still pass.
Creates the 9-project .NET 8 solution (5 src + 4 test) with Marathon.Domain
fully implemented: value objects (SportCode, EventId, OddsRate, OddsValue,
BetScope hierarchy), enums (Side, BetType, OddsSource, AnomalyKind), and
entities (Sport, Country, League, Event, Bet, OddsSnapshot, EventResult,
Anomaly) with all invariants enforced in constructors. 96 domain tests pass
(FluentAssertions + xUnit). Directory.Build.props and Directory.Packages.props
centralise build settings and NuGet versions. Both Marathon.sln and Marathon.slnx
are committed; dotnet build Marathon.sln succeeds with 0 warnings/errors.
