+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+**Elapsed** is a cross-platform native timelapse app for Hack Club's Lapse platform. It includes a multi-platform desktop/mobile UI (Uno Platform + .NET 10), a CLI tool, and supporting libraries.
+
+- .NET 10 SDK, C# 14, file-scoped namespaces, implicit usings, nullable enabled
+- Solution file: Elapsed.slnx
+
+## Solution Structure
+
+### Platform Projects (Executables)
+
+- **Riverside.Elapsed.App** (`src/platforms/Riverside.Elapsed.App/`) — Uno Platform app targeting net10.0-desktop, net10.0-android, net10.0-ios, net10.0-browserwasm, net10.0-windows10.0.26100.0. MVVM architecture with Views, ViewModels, Models, Services. Startup project for debugging.
+- **Riverside.Elapsed.CommandLine** (`src/platforms/Riverside.Elapsed.CommandLine/`) — .NET console app (net10.0) using System.CommandLine. Exposes the full Lapse API with JSON output. Installable as a dotnet tool.
+
+### Core Libraries (Shared)
+
+- **Riverside.Elapsed** (`src/core/Riverside.Elapsed/`) — .NET Standard 2.1. Lapse API projection auto-generated by Kiota from the OpenAPI spec at `https://api.lapse.hackclub.com/openapi.json`. Downloads the spec at build time.
+- **Riverside.MediaRecording** (`src/core/Riverside.MediaRecording/`) — .NET 10 cross-platform media recording (camera, screen, microphone). Platform-specific code in `Windows/` subdirectory.
+- **Riverside.ResumableUploads** (`src/core/Riverside.ResumableUploads/`) — .NET Standard 2.1 TUS protocol client for resumable uploads.
+
+## Build Commands
+
+```bash
+# Restore workloads (required first time)
+dotnet workload restore src/platforms/Riverside.Elapsed.App/Riverside.Elapsed.App.csproj
+
+# Build desktop target
+dotnet build src/platforms/Riverside.Elapsed.App/Riverside.Elapsed.App.csproj -f net10.0-desktop
+
+# Build Windows target
+dotnet build src/platforms/Riverside.Elapsed.App/Riverside.Elapsed.App.csproj -f net10.0-windows10.0.26100.0
+
+# Build WebAssembly
+dotnet build src/platforms/Riverside.Elapsed.App/Riverside.Elapsed.App.csproj -f net10.0-browserwasm
+
+# Build CLI
+dotnet build src/platforms/Riverside.Elapsed.CommandLine/Riverside.Elapsed.CommandLine.csproj
+
+# Publish (any target, add -c Release for release builds)
+dotnet publish src/platforms/Riverside.Elapsed.App/Riverside.Elapsed.App.csproj -f net10.0-desktop -c Release
+```
+
+VS Code tasks are preconfigured in `.vscode/tasks.json`: build-wasm, publish-wasm, build-desktop, publish-desktop, build-windows, publish-windows.
+
+Build artifacts go to `bin/{ProjectName}/AnyCPU/{Configuration}/{TargetFramework}/`. Web builds use a relative `wwwroot/` path due to an Uno Wasm Bootstrap SDK bug.
+
+## Code Style
+
+- **Tabs** for indentation (not spaces)
+- **File-scoped namespaces** (enforced as warning in .editorconfig)
+- **American English** in code, **British English** in documentation and comments
+- PascalCase for types/methods/properties, camelCase for locals, `I` prefix for interfaces
+- See `.editorconfig` for full Roslyn analyzer rules
+
+## Architecture
+
+### App (MVVM with Uno Extensions)
+
+- Services registered via `IHost` dependency injection in `App.xaml.cs`
+- Navigation via `INavigator` (Uno.Extensions.Navigation)
+- ViewModels use `ObservableObject` and `RelayCommand` (CommunityToolkit.Mvvm)
+- Configuration loaded from `appsettings.json` into `AppConfig`
+- UnoFeatures enabled: Hosting, Toolkit, Mvvm, Configuration, HttpKiota, Serialization, Localization, Authentication, Navigation, ThemeService, SkiaRenderer, Lottie, Logging/Serilog
+
+Key service areas under `Services/`:
+- `Auth/` — OAuth token management via ILapseAuthService
+- `Api/` — Kiota-generated API service interfaces
+- `Storage/` — Local app data persistence
+- `Recording/` — Media recording (desktop/Windows only, gated by `HAS_MEDIA_RECORDING` define)
+- `Drafts/` — Draft timelapse management
+- `Build/` — Build metadata (version, timestamp generated at compile time via MSBuild target)
+
+### Platform-Specific Code
+
+Platform code lives in `Platforms/{Android,iOS,Desktop,WebAssembly}/` within the App project. Uno's single-project structure uses conditional compilation. The `HAS_MEDIA_RECORDING` define is set for desktop and Windows TFMs only.
+
+### Lapse API Projection
+
+The `Riverside.Elapsed` library uses the `Riverside.CompilerPlatform.CSharp.Features.Kiota` source generator. At build time, the OpenAPI spec is downloaded and C# client code is generated. The generated client uses Kiota's `IRequestAdapter` pattern. Do not manually edit generated API code.
+
+## Versioning & Releases
+
+Version is controlled in `eng/CurrentVersion.props`. Format: `{MAJOR}.{MINOR}.{YYMMDD}[-{LEVEL}{BETA}]` (e.g., `0.4.260531`, `2.1.260220-preview2`).
+
+- Debug builds automatically get a `-preview1` suffix
+- Release levels: `alpha`, `beta`, `preview`, `rc`, `final` (final hides the suffix)
+- Changing `eng/CurrentVersion.props` on main triggers the CD pipeline, which publishes to GitHub Releases, NuGet, and Vercel (web)
+
+## CI/CD
+
+GitHub Actions in `.github/workflows/ci.yml`:
+- Triggers on push to main, PRs, and manual dispatch
+- Matrix builds across all target frameworks in Debug and Release
+- XAML formatting validation with XamlStyler
+- Runs on Windows Server 2025 with VS 2026
+
+## Testing
+
+No test projects exist yet. The CI pipeline has unit test jobs commented out.
+
+## Important Notes
+
+- **Native AOT & Trimming**: Desktop/Windows release builds use Native AOT. The CLI uses reflection and is NOT AOT-safe — it ships separately.
+- **Kiota regeneration**: The API library auto-regenerates on build if the OpenAPI spec changes. Don't edit generated code.
+- **HAS_MEDIA_RECORDING**: Conditional define only set for `-desktop` and `-windows` TFMs. Guard media recording code behind `#if HAS_MEDIA_RECORDING`.
+- **Localization**: String resources in `Strings/` directory, multiple languages supported.
+- **Design reference**: Figma mockups at https://www.figma.com/design/dUoOj27yGtoY3Y6HRKYJnF/Elapsed--WinUI-3-

+##### CLI
+
+Building Elapsed with the MSBuild CLI is a great way to quickly test whether the app builds, as the MSBuild CLI does not rely on GUI-heavy apps such as Visual Studio.
+It is recommended to use the .NET Framework version of MSBuild as it works best for the tech stack that the Elapsed project consumes.
+
+- Restore the project dependencies via NuGet
+
+```bash
+msbuild -t:Restore -p:Configuration=Release
+```
+
+- Build/publish the project of your choice, such as `Riverside.Elapsed.App` for the main app project.
+
+You must specify a `TargetFramework` property when building the app project, such as `net10.0-desktop`, `net10.0-windows`, or `net10.0-browserwasm`.
+When building the Windows head of the app project, it is recommended to debug via an IDE such as Visual Studio as an IDE will provide a better experience for building WinUI apps.
+It is also recommended to make use of the `Publish` task when building the WebAssembly/WinAppSDK/Skia heads as this will ensure the output is production ready.
+
+```bash
+msbuild src\platforms\Riverside.Elapsed.App -t:Publish -p:Configuration=Release -p:TargetFramework=net10.0-desktop
+```
+
+The build output can always be found in the `bin` folder of the project root directory.
