Oleksandr Bezdieniezhnykh b0fffa6d42 [AZ-284] Autodev baseline + testability refactor 
Phase A baseline outputs from /autodev (Steps 1-5):
- Problem & solution docs (_docs/00_problem, _docs/01_solution)
- Codebase documentation (_docs/02_document) incl. architecture,
  module-layout, glossary, system-flows, baseline compliance scan
- Test specs (blackbox, performance, resilience, security, resource,
  traceability matrix)
- Test task decomposition (_docs/02_tasks/todo): AZ-285..AZ-290
- Testability refactor (_docs/04_refactoring/01-testability-refactoring):
  - TC-01 Move DownloadedTileInfoV2 + new ExistingTileInfo to Common.DTO
  - TC-02 Replace dead ISatelliteDownloader API with real signatures
  - TC-03 GoogleMapsDownloaderV2 implements ISatelliteDownloader
  - TC-04 TileService depends on ISatelliteDownloader (mockable)
  - TC-05 DI + endpoints use ISatelliteDownloader
- Test runner scripts (scripts/run-tests.sh, run-performance-tests.sh)
- Autodev state pointer (_docs/_autodev_state.md)

Prepares the codebase for AZ-285..AZ-290 unit/integration test work.

Module Layout

Status: derived-from-code

Language: csharp Layout Convention: custom (flat service project, per-project component separation) Root: ./ Last Updated: 2026-05-10

Layout Rules

  1. Each component owns ONE top-level project directory (.csproj boundary), except the Services project which hosts three logical components in a flat layout.
  2. Shared code lives under SatelliteProvider.Common/ — the foundation layer.
  3. Cross-cutting concerns (DTOs, interfaces, configs, geo-math) all reside in Common.
  4. Public API surface per component = public types in the namespace root. Everything marked internal or private is internal.
  5. Tests live in separate projects: SatelliteProvider.Tests/ (unit) and SatelliteProvider.IntegrationTests/ (integration).

Per-Component Mapping

Component: Common

  • Directory: SatelliteProvider.Common/
  • Public API:
    • SatelliteProvider.Common/Configs/MapConfig.cs
    • SatelliteProvider.Common/Configs/StorageConfig.cs
    • SatelliteProvider.Common/Configs/ProcessingConfig.cs
    • SatelliteProvider.Common/Configs/DatabaseConfig.cs
    • SatelliteProvider.Common/DTO/*.cs (all DTOs)
    • SatelliteProvider.Common/Interfaces/*.cs (all service interfaces)
    • SatelliteProvider.Common/Utils/GeoUtils.cs
  • Internal: (none — all types are public, shared across components)
  • Owns: SatelliteProvider.Common/**
  • Imports from: (none)
  • Consumed by: DataAccess, TileDownloader, RegionProcessing, RouteManagement, WebApi

Component: DataAccess

  • Directory: SatelliteProvider.DataAccess/
  • Public API:
    • SatelliteProvider.DataAccess/Models/TileEntity.cs
    • SatelliteProvider.DataAccess/Models/RegionEntity.cs
    • SatelliteProvider.DataAccess/Models/RouteEntity.cs
    • SatelliteProvider.DataAccess/Models/RoutePointEntity.cs
    • SatelliteProvider.DataAccess/Repositories/ITileRepository.cs
    • SatelliteProvider.DataAccess/Repositories/IRegionRepository.cs
    • SatelliteProvider.DataAccess/Repositories/IRouteRepository.cs
    • SatelliteProvider.DataAccess/Repositories/TileRepository.cs
    • SatelliteProvider.DataAccess/Repositories/RegionRepository.cs
    • SatelliteProvider.DataAccess/Repositories/RouteRepository.cs
    • SatelliteProvider.DataAccess/DatabaseMigrator.cs
  • Internal: (none — all repository types are public for DI registration)
  • Owns: SatelliteProvider.DataAccess/**
  • Imports from: (none — fully self-contained, no project references)
  • Consumed by: TileDownloader, RegionProcessing, RouteManagement, WebApi

Component: TileDownloader

  • Directory: SatelliteProvider.Services/ (shared project)
  • Public API:
    • SatelliteProvider.Services/GoogleMapsDownloaderV2.cs (implements ISatelliteDownloader)
    • SatelliteProvider.Services/TileService.cs (implements ITileService)
  • Internal: (none — flat project, classes are public)
  • Owns: SatelliteProvider.Services/GoogleMapsDownloaderV2.cs, SatelliteProvider.Services/TileService.cs
  • Imports from: Common, DataAccess
  • Consumed by: RegionProcessing, WebApi

Component: RegionProcessing

  • Directory: SatelliteProvider.Services/ (shared project)
  • Public API:
    • SatelliteProvider.Services/RegionService.cs (implements IRegionService)
    • SatelliteProvider.Services/RegionProcessingService.cs (background hosted service)
    • SatelliteProvider.Services/RegionRequestQueue.cs (implements IRegionRequestQueue)
  • Internal: (none)
  • Owns: SatelliteProvider.Services/RegionService.cs, SatelliteProvider.Services/RegionProcessingService.cs, SatelliteProvider.Services/RegionRequestQueue.cs
  • Imports from: Common, DataAccess, TileDownloader
  • Consumed by: RouteManagement, WebApi

Component: RouteManagement

  • Directory: SatelliteProvider.Services/ (shared project)
  • Public API:
    • SatelliteProvider.Services/RouteService.cs (implements IRouteService)
    • SatelliteProvider.Services/RouteProcessingService.cs (background hosted service)
  • Internal: (none)
  • Owns: SatelliteProvider.Services/RouteService.cs, SatelliteProvider.Services/RouteProcessingService.cs
  • Imports from: Common, DataAccess, RegionProcessing
  • Consumed by: WebApi

Component: WebApi

  • Directory: SatelliteProvider.Api/
  • Public API:
    • SatelliteProvider.Api/Program.cs (minimal API endpoints, DI setup)
  • Internal: (none)
  • Owns: SatelliteProvider.Api/**
  • Imports from: Common, DataAccess, TileDownloader, RegionProcessing, RouteManagement
  • Consumed by: (none — top-level entry point)

Shared / Cross-Cutting

Common/Configs

  • Directory: SatelliteProvider.Common/Configs/
  • Purpose: Strongly-typed configuration POCOs bound via IOptions<T>
  • Consumed by: all components

Common/DTO

  • Directory: SatelliteProvider.Common/DTO/
  • Purpose: Data transfer objects shared across layers (request/response models, value types)
  • Consumed by: all components

Common/Interfaces

  • Directory: SatelliteProvider.Common/Interfaces/
  • Purpose: Service contracts enabling DI and testability
  • Consumed by: all components (services implement, API and consumers depend on)

Common/Utils

  • Directory: SatelliteProvider.Common/Utils/
  • Purpose: Stateless geospatial utility functions (coordinate math, distance, bearing)
  • Consumed by: TileDownloader, RegionProcessing, RouteManagement

Allowed Dependencies (layering)

Layer Components May import from
4. API / Entry WebApi 1, 2, 3
3. Application (Orchestration) RouteManagement 1, 2, 3 (RegionProcessing only)
3. Application (Processing) RegionProcessing 1, 2, 3 (TileDownloader only)
2. Domain Services TileDownloader 1
1. Foundation Common, DataAccess Common: (none); DataAccess: (none)

Verification Needed

  • Shared Services project: TileDownloader, RegionProcessing, and RouteManagement coexist in a single SatelliteProvider.Services/ project. File-level ownership is used (not directory-level) which is unusual for .NET. A future refactor into separate projects per component would make ownership boundaries cleaner.
  • No detected cycles: The dependency graph is a clean DAG.
  • DataAccess layer placement: DataAccess is placed at Layer 1 (Foundation) alongside Common because it is consumed uniformly by all service components. An alternative layering could place it at Layer 2, but the current code treats repositories as infrastructure, not domain logic.
