feat: project setup and core models with TDD

MILESTONE 1 COMPLETE: Project Setup: - Create .NET 8 MAUI solution targeting iOS, macOS, and web - Configure nullable reference types and warnings as errors - Add required dependencies (MAUI 8.0.3, SQLite, CommunityToolkit.Mvvm) - Add testing dependencies (xUnit, NSubstitute, FluentAssertions, Coverlet) - Create comprehensive .editorconfig with C# coding standards - Update CLAUDE.md with development commands Core Models (TDD - 48 tests, all passing): - EstimateMode enum (Work, Generic, Humorous modes) - EstimateResult model with validation (intensity 0.0-1.0, non-null text) - ShakeData model with intensity validation - AppSettings model with defaults (Work mode, max history 10) Build Status: - All platforms build successfully (net8.0, iOS, macOS) - 0 warnings, 0 errors - Test coverage: 51.28% line, 87.5% branch (models have ~100% coverage) Per spec: Strict TDD followed (RED-GREEN-REFACTOR), models fully validated 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

+
+## Project Overview
+
+Hiha-Arvio (Finnish: "Sleeve Estimate") is a .NET 8 MAUI cross-platform application that generates semi-random time estimates based on physical shake input (accelerometer on mobile, mouse movement on desktop). This is a humor app for "pulling an estimate from your sleeve."
+
+**Platforms (in priority order):** iOS (primary) → Web (Blazor) → macOS
+
+## Critical Requirements
+
+### Specification Compliance
+
+- **ALWAYS read `spec.md` before implementing features** - contains RFC 2119 formal requirements (MUST, REQUIRED, SHALL)
+- **Design reference:** `docs/plans/2025-11-18-hiha-arvio-design.md` contains validated architecture decisions
+- Nullable reference types MUST be enabled
+- All compiler warnings MUST be treated as errors
+- Minimum test coverage: 95% (enforced in CI/CD)
+
+### Architecture Constraints
+
+**MVVM Pattern with Strict Separation:**
+- Models: Plain data objects only, no business logic
+- ViewModels: All presentation logic, must be 100% testable without UI dependencies
+- Views: Thin layer, data binding only, minimal presentation code
+- Services: All business logic and infrastructure concerns
+
+**Dependency Injection:**
+- All services MUST be injected via constructor (no service locator, no `new` keyword in ViewModels)
+- Register services in `MauiProgram.cs`
+- Platform-specific implementations use conditional compilation (`#if IOS`, `#elif WINDOWS || MACCATALYST`)
+
+### Testing Requirements
+
+- Test coverage MUST be ≥95% (measured with Coverlet, enforced in CI/CD)
+- Testing stack: xUnit + NSubstitute (mocking) + FluentAssertions (assertions)
+- All tests MUST use deterministic randomness (seeded RNG)
+- Mock all external dependencies (sensors, database, file system)
+- Use test data builders for complex objects
+
+## Technology Stack
+
+- **Framework:** .NET 8 MAUI (LTS)
+- **Language:** C# 12 with nullable reference types
+- **Database:** SQLite via `sqlite-net-pcl`
+- **MVVM:** CommunityToolkit.Mvvm (source generators)
+- **Testing:** xUnit, NSubstitute, FluentAssertions, Coverlet
+
+## Core Architecture
+
+### Service Layer (All Injectable)
+
+**IAccelerometerService**
+- Platform abstraction: accelerometer (iOS) or mouse movement (desktop/web)
+- Emits observable stream of sensor data
+
+**IShakeDetectionService**
+- Processes accelerometer stream
+- Detects shake start/stop, calculates normalized intensity [0.0-1.0]
+- Tracks shake duration for easter egg trigger (>15 seconds)
+
+**IEstimateService**
+- Generates estimates based on: intensity, duration, mode
+- Implements intensity → range mapping:
+  - Intensity <0.3: narrow range (first 20% of pool)
+  - Intensity 0.3-0.7: medium range (first 50% of pool)
+  - Intensity >0.7: full range (entire pool)
+- Easter egg: duration >15s forces Humorous mode
+- MUST use cryptographically secure RNG (`System.Security.Cryptography.RandomNumberGenerator`)
+
+**IStorageService**
+- Settings: Preferences API
+- History: SQLite with auto-pruning (max 10 estimates)
+- All operations MUST be async
+
+### Key Models
+
+```csharp
+EstimateResult: Id, Timestamp, EstimateText, Mode, ShakeIntensity, ShakeDuration
+EstimateMode enum: Work, Generic, Humorous
+ShakeData: Intensity, Duration, IsShaking
+AppSettings: SelectedMode, MaxHistorySize
+```
+
+### Estimate Pools (from spec.md §3.2.2)
+
+**Work Mode:**
+- Gentle: "2 hours", "4 hours", "1 day", "2 days", "3 days", "5 days", "1 week"
+- Hard: adds "15 minutes", "30 minutes", "2 weeks", "1 month", "3 months", "6 months", "1 year"
+
+**Generic Mode:**
+- Gentle: "1 minute" → "3 hours"
+- Hard: "30 seconds" → "1 month"
+
+**Humorous Mode (easter egg):**
+- "tomorrow", "eventually", "next quarter", "when hell freezes over", "3 lifetimes", "Tuesday", "never", "your retirement"
+
+## Platform-Specific Implementation
+
+### iOS (Primary Platform)
+- Accelerometer via `Microsoft.Maui.Devices.Sensors.Accelerometer`
+- Shake detection: `magnitude = sqrt(x² + y² + z²)`, threshold 2.5g
+- Must request motion permissions in Info.plist
+- Haptic feedback on shake detection (recommended)
+- Target iOS 15+
+
+### Web (Blazor WebAssembly)
+- Mouse movement simulation: track delta over 200ms window, calculate velocity
+- PWA manifest for home screen install
+- Support Device Orientation API for mobile browsers (optional)
+
+### macOS
+- Mouse movement tracking (similar to web)
+- Keyboard shortcut: Cmd+Shift+S for manual shake trigger
+- Native menu bar integration
+

+## Development Commands
+
+### Build Commands
+- **Build all platforms:** `dotnet build HihaArvio.sln`
+- **Build specific framework:** `dotnet build HihaArvio.sln -f net8.0`
+- **Build iOS:** `dotnet build HihaArvio.sln -f net8.0-ios`
+- **Build macOS:** `dotnet build HihaArvio.sln -f net8.0-maccatalyst`
+
+### Test Commands
+- **Run all tests:** `dotnet test tests/HihaArvio.Tests/HihaArvio.Tests.csproj`
+- **Run specific test class:** `dotnet test tests/HihaArvio.Tests/HihaArvio.Tests.csproj --filter "FullyQualifiedName~EstimateModeTests"`
+- **Run single test:** `dotnet test --filter "FullyQualifiedName~TestClassName.TestMethodName"`
+
+### Code Coverage
+- **Generate coverage:** `dotnet test tests/HihaArvio.Tests/HihaArvio.Tests.csproj --collect:"XPlat Code Coverage"`
+- **Coverage files:** Located in `tests/HihaArvio.Tests/TestResults/{guid}/coverage.cobertura.xml`
+
+### Run Commands
+- **iOS Simulator:** `dotnet build src/HihaArvio/HihaArvio.csproj -t:Run -f net8.0-ios`
+- **macOS:** `dotnet build src/HihaArvio/HihaArvio.csproj -t:Run -f net8.0-maccatalyst`
+
+### Notes
+- All commands should be run from the repository root directory
+- Xcode must be installed and configured (`xcode-select -p` should point to Xcode.app)
+- MAUI workload must be installed (`dotnet workload list` should show `maui`)
+
+## Critical Implementation Notes
+
+### Easter Egg Behavior
+- Hidden feature: NO UI indication
+- Trigger: shake duration >15 seconds
+- Effect: temporarily force EstimateMode.Humorous
+- Do NOT expose in Settings or UI
+
+### Shake Detection Algorithm
+1. Monitor sensor stream (accelerometer or mouse)
+2. Calculate magnitude/velocity
+3. Detect start: exceeds threshold
+4. Track peak intensity during session
+5. Detect end: below threshold for 500ms continuous
+6. Normalize to [0.0, 1.0]
+
+### Performance Requirements
+- Shake response: <100ms latency
+- Estimate display: <200ms after shake stop
+- History load: <500ms
+- All database operations: async, non-blocking
+
+### Security
+- Use `System.Security.Cryptography.RandomNumberGenerator` for estimate selection
+- No external data transmission
+- All data stored locally only
+- Request minimum required permissions
+
+## Code Quality Enforcement
+
+- Enable nullable reference types across all projects
+- Treat warnings as errors
+- Follow EditorConfig rules (when defined)
+- Code analysis: StyleCop + built-in analyzers enabled
+- CI/CD must enforce 95% coverage threshold and fail builds below this
+
+## Important Implementation Order
+
+Per design document, phased development:
+1. **Phase 1:** iOS app (primary platform, accelerometer-based)
+2. **Phase 2:** Web app (Blazor, mouse simulation)
+3. **Phase 3:** macOS app (native integration)
+
+Focus on Phase 1 first to validate core shake detection and estimate generation logic.
