Persist named backtest-strategy presets so a staking config (bankroll,
min-score, stake rule, flat/percent/Kelly params) can be saved, listed,
loaded back into the form, and deleted. The per-run date range is not
part of a preset.
- Domain: SavedStrategy record (name trimmed + bounded to 80 chars,
Create() factory) wrapping the pure BacktestStrategy.
- Persistence: SavedStrategyEntity + config (TEXT decimals, unique
case-insensitive NOCASE index on Name), repository, mapping, and a
hand-trimmed AddSavedStrategies migration (additive — only the new
table). Case-insensitive names mean save-by-name overwrites instead of
creating near-duplicates.
- Application: SaveStrategyUseCase (upsert by name, keeps Id+CreatedAt) +
DeleteStrategyUseCase.
- UI: presets panel on the Backtest page (load/save/delete) + service
methods; fraction<->percent round-trip; en/ru resx.
- Fix: pin Sports.Code as ValueGeneratedNever — it is the bookmaker's
natural sport id, not an autoincrement surrogate. Corrects long-standing
model-snapshot drift; the snapshot is regenerated to match the DB.
- 25 tests across all four layers: domain validation, real-SQLite
round-trip incl. case-insensitive lookup/uniqueness, the upsert use
case, and the service percent mapping.
- 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.
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.

Six MEDIUM-tier review items:
* Mapping.cs — DateTimeOffset.Parse now passes CultureInfo.InvariantCulture
+ DateTimeStyles.RoundtripKind so a non-en-US thread culture cannot
corrupt round-tripped ScheduledAt / CapturedAt / DetectedAt / CompletedAt.
Also replaces the magic 0/1 BetScope discriminator with named constants.
* Delete dead Placeholder.cs files in Marathon.Application and
Marathon.Infrastructure — they were stubs from Phase 1 to satisfy
"non-empty project" and have been dead since Phase 2/3.
* EventBrowsingService — drop the bespoke ScopeEqualityComparer; BetScope
is a record hierarchy, .GroupBy uses value equality natively.
* UserAgentRotatorHandler — counter promoted to private static int with
Interlocked.Increment so rotation is round-robin across the process.
HttpClientFactory builds the handler Transient, so the previous instance
field reset to zero on every new client and broke rotation.
* EventOddsParser — added a parallel "selection-key → IElement" index
alongside the existing price index. Handicap extraction (6 call sites
per event detail page) used to do a fresh document.QuerySelector("span[
data-selection-key='...']") for every key — full-document CSS traversal.
Now it's a dictionary lookup, with the pair-emit logic factored into a
shared TryEmitHandicapPair helper.
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.
