…tics dashboard (#44) ## Summary This pull request upgrades the `MetricsView` in `HidGuard.App` into a real-time hardware telemetry visualizer and timing diagnostics dashboard, exposing granular statistical distributions, live inter-keystroke interval strips, and diagnostic session controls. ## Key Changes - **TimingHistogramBucket**: Introduced observable bucket model mapping keystroke interval density across 6 ranges (<10ms, 10-25ms, 25-60ms, 60-150ms, 150-300ms, >300ms) with dynamic percentage calculations and scaled visual bar heights. - **LiveIntervalSample**: Added color-coded live interval sample records indicating anomalous vs. benign keystroke speeds. - **MetricsViewModel Expansion**: - Computed advanced dynamics metrics: Coefficient of Variation (`CoefficientOfVariation`), Sub-Human Ratio percentage (`SubHumanRatioPercent`), Minimum Interval (`MinimumIntervalMs`), Continuous Burst Length (`BurstLength`), Human Confidence Score (`HumanConfidenceScore`), and Bot Probability Score (`BotProbabilityScore`). - Added `ActiveDeviceId` telemetry binding. - Implemented `ResetMetricsCommand` allowing security operators to reset histograms, sample buffers, and diagnostic counters. - **MetricsView XAML**: - Redesigned status card featuring Human Confidence vs. Anomaly Score side-by-side gauge meters. - Added 4-card telemetry metric grid (Speed, Mean Interval, CV Variability, Sub-Human Ratio). - Integrated 6-column hardware timing distribution histogram with percentage labels and color-coded bars. - Embedded real-time keystroke interval stream strip showing the last 30 intervals with color-coded severity. - Added diagnostic session telemetry card with active hardware ID and one-click "Reset Diagnostics" action. - **Unit Tests**: Added `MetricsViewModelTests` validating initial state defaults, evaluation recording, histogram bucket distribution, anomaly threshold styling, and metrics reset. Solution test count increased from 266 to 270 passing tests with zero warnings under TreatWarningsAsErrors. - **Documentation**: Updated `README.md` and `README.tr.md` test suite scope tables. ## Verification - `dotnet test HidGuard.sln --configuration Release`: 270 / 270 tests passed (100% green). - `dotnet run --project tools/HidGuard.Simulator/HidGuard.Simulator.csproj --configuration Release --no-build -- --verify`: 7 / 7 verification scenarios passed. - All code follows zero-comment and zero-emoji compliance.
