# Feature Context: Initial Implementation

## Configuration

- **Development mode:** Automated
- **Execution mode:** Orchestrator
- **Strategy:** Big Bang
- **Build:** `dotnet build Marathon.sln`
- **Test:** `dotnet test Marathon.sln`
- **Lint:** `dotnet format Marathon.sln --verify-no-changes`
- **Run:** `dotnet run --project src/Marathon.Hosts.WpfBlazor`
- **Implementer models:** Sonnet 4.6 (backend), Opus (frontend)
- **Reviewer model:** Sonnet 4.6

## Customer Constraints

- Source: marathonbet.by — anonymous scraping (no login). ToS risk acknowledged by customer.
- Output: Excel files matching customer's wide-column spec (`Bet_Match_Win_1`,
  `Bet_Period-1_Win_Fora_2_Value`, etc.) with date-range filenames.
- Storage: customer accepted SQLite-with-Excel-export instead of Excel-as-database
  (decided 2026-05-05).
- UI tech: Blazor Hybrid (changed from initial WPF assumption — better for web migration).
- Locale: RU + EN.
- Scope: analyze-only initially; design `IBetPlacer` extension point for future betting.
- Configurability: every variable parameter (polling, concurrency, retry, UA, retention,
  thresholds, locale) goes in `appsettings.json` + Settings UI page.

## Current State

Repo just initialized. Single `main` commit with `.gitignore` + `README.md` + `CLAUDE.md`.
Working on `feature/initial-implementation` branch. No source code yet — Phase 0 starts
with scraping research, no implementation.

## Temporary Workarounds

(none yet)

## Cross-Phase Dependencies

- **Phase 1 (Domain)** is the foundation; all later phases reference domain types.
- **Phase 2 (Storage)** & **Phase 3 (Scraping)** depend only on Phase 1 — can run in parallel.
- **Phase 4 (Application + Workers)** depends on Phase 2 + Phase 3.
- **Phase 5 (UI Shell)** depends on Phase 1 only — can run in parallel with 2/3.
- **Phase 6 (Event Browsing UI)** depends on Phase 4 + Phase 5.
- **Phase 7 (Anomaly)** depends on Phase 4 (snapshot storage) + Phase 6 (UI patterns).
- **Phase 8 (Results)** depends on Phase 6.
- **Phase 9 (Packaging)** is final — runs full build + test suite.

## Deferred Work

- Bet placing (explicit out-of-scope; design extension point only).
- Authenticated scraping (anonymous now; `IOddsScraper` impl is swappable).
- Multi-bookmaker support (only marathonbet.by; abstraction allows future expansion).
- PostgreSQL backend (SQLite for now; `IRepository<T>` abstraction allows swap).

## Environment & Runtime Notes

- Windows 10, PowerShell 5.1 default shell, Bash also available.
- `git` configured globally; remote `origin` = `https://git.dolgolyov-family.by/alexei.dolgolyov/maraphon-app.git`.
- Note: home directory (`C:\Users\Alexei`) is itself a git repo (likely accidental).
  The maraphon-app local `.git` overrides it for this directory tree.
- .NET SDK assumed installed; if Phase 1 fails on `dotnet --version`, install or
  document in CONTEXT.md.
