-You need a GitHub PAT with `read:packages` permission.
+## Code Standards & Conventions
+
+**IMPORTANT:** Always study existing code in the relevant area before making changes. Match the existing style exactly.
+
+### Backend (C#)
+- Follow Microsoft C# Coding Conventions
+- Use nullable reference types (`<Nullable>enable</Nullable>`)
+- Add XML documentation comments for public APIs
+- Use meaningful names - avoid abbreviations unless widely understood
+- Keep services focused - single responsibility principle
+- New integrations go under `Features/` subdirectories (e.g., `Infrastructure/Features/Arr/`)
+
+### Frontend (TypeScript/Angular)
+- All components must be **standalone** with **ChangeDetectionStrategy.OnPush**
+- Use `input()` / `output()` function APIs (not `@Input()` / `@Output()` decorators)
+- Use Angular **signals** for reactive state (`signal()`, `computed()`, `effect()`)
+- Follow the 3-layer SCSS design system (`_variables` -> `_tokens` -> `_themes`)
+- **Do not introduce external UI frameworks** (no PrimeNG, Material, Tailwind, etc.)
+- Component naming: `{feature}.component.ts`
+- Service naming: `{feature}.service.ts`
+- **Look at similar existing components before creating new ones**
+
+### Testing
+- **Backend**: xUnit + NSubstitute + Shouldly
+- Always use **NSubstitute** for mocking (Moq is being phased out)
+- Write unit tests for new features and bug fixes
+- Use descriptive test names that explain what is being tested
+- No frontend unit tests currently
+
+### Git Commit Messages
+- Use clear, descriptive messages in imperative mood
+- Examples: "Add Discord notification support", "Fix memory leak in download client polling"
+- Reference issue numbers when applicable: "Fix #123: Handle null response from Radarr API"

-## Code Standards & Conventions
-
-**IMPORTANT:** Always study existing code in the relevant area before making changes. Match the existing style exactly.
-
-### Backend (C#)
-- Follow [Microsoft C# Coding Conventions](https://docs.microsoft.com/dotnet/csharp/fundamentals/coding-style/coding-conventions)

-- Add XML documentation comments for public APIs
-- Write unit tests for business logic
-- Use meaningful names - avoid abbreviations unless widely understood
-- Keep services focused - single responsibility principle
-- **Study existing service implementations before creating new ones**
-
-### Frontend (TypeScript/Angular)
-- Follow [Angular Style Guide](https://angular.io/guide/styleguide)
-- Use TypeScript strict mode
-- All components must be **standalone** (no NgModules) with **ChangeDetectionStrategy.OnPush**
-- Use `input()` / `output()` function APIs (not `@Input()` / `@Output()` decorators)
-- Use Angular **signals** for reactive state (`signal()`, `computed()`, `effect()`)
-- Follow the 3-layer SCSS design system (`_variables` → `_tokens` → `_themes`) for styling
-- Component naming: `{feature}.component.ts`
-- Service naming: `{feature}.service.ts`
-- **Look at similar existing components before creating new ones**
-
-### Testing
-- Write unit tests for new features and bug fixes
-- Use descriptive test names that explain what is being tested
-- Backend: xUnit or NUnit conventions
-- Frontend: Jasmine/Karma
-- **Test that existing functionality still works after changes**
-
-### Git Commit Messages
-- Use clear, descriptive messages in imperative mood
-- Examples: "Add Discord notification support", "Fix memory leak in download client polling"
-- Reference issue numbers when applicable: "Fix #123: Handle null response from Radarr API"
-
-### Discovering Issues
-If you encounter potential gotchas, common mistakes, or areas that need special attention during development:
-- **Flag them to the maintainer immediately**
-- Document them if confirmed
-- Consider if they should be added to this guide
-
 ## Database Migrations
 
-Cleanuparr uses two separate database contexts:
-- **DataContext**: Main application data
-- **EventsContext**: Event logging and audit trail
-
-### Creating Migrations
-From the `code` directory:
+Three separate database contexts, all commands run from the `code` directory:
 
 ```bash
-# Data migrations
+# Data migrations (DataContext)
 make migrate-data name=YourMigrationName
 
-# Events migrations
+# Events migrations (EventsContext)
 make migrate-events name=YourMigrationName
-```
 
-Example:
-```bash
-make migrate-data name=AddDownloadClientConfig
-make migrate-events name=AddStrikeEvents
+# Users migrations (UsersContext)
+make migrate-users name=YourMigrationName
 ```

-## Working with Claude - IMPORTANT
-
-### Core Principles
-1. **When in doubt, ASK** - Don't assume, clarify with the maintainer first
-2. **Don't break existing functionality** - Everything is important and needs to work
-3. **Follow existing coding style** - Study the codebase patterns before making changes
-4. **Use current coding standards** - If you want to introduce something new, ask first
-
-### When Modifying Code
-- **ALWAYS read existing files before suggesting changes**
-- Understand the current architecture and patterns
-- Prefer editing existing files over creating new ones
-- Follow the established conventions in the codebase exactly
-- Test changes locally when possible
-- **If you're unsure about an approach, ask before implementing**
-
-### When Adding Features
-- Review similar existing features first to understand patterns
-- Maintain consistency with existing UI/UX patterns
-- Update both backend and frontend together
-- Add/update documentation
-- Consider backwards compatibility
-- **Ask about architectural decisions before implementing new patterns**
-
-### When Fixing Bugs
-- Understand the root cause before proposing a fix
-- **Be careful not to break other functionality** - test related areas
-- Add tests to prevent regression
-- Update relevant documentation if behavior changes
-- Consider if other parts of the codebase might have similar issues
-- **Flag any potential gotchas or issues you discover**
-
-## Notes
+## Key Gotchas
 
+- **Custom glassmorphism design system** - Do not introduce external UI frameworks (no PrimeNG, Material, Tailwind)
+- **All frontend components** must be standalone with OnPush change detection
+- **Database migrations** require awareness of all three contexts (Data, Events, Users)
+- **Malware blocker** is a critical security feature - changes require careful testing
+- **Cross-seed integration** allows keeping torrents that are actively seeding
+- **Real-time updates** use SignalR - maintain websocket patterns when adding features
+- Use `@ng-icons/core` + `@ng-icons/tabler-icons` for icons (NOT `angular-tabler-icons` which doesn't support Angular 21)
+- **Sidebar** stays dark purple in both themes - uses sidebar-specific CSS variables
 - The project uses **Clean Architecture** - respect layer boundaries
-- Database migrations require both contexts - don't forget EventsContext
-- Frontend uses a **custom glassmorphism design system** - don't introduce external UI frameworks (no PrimeNG, Material, etc.)
-- All frontend components are **standalone** with **OnPush** change detection
-- All downloads from *arr apps are processed through a **strike system**
-- The malware blocker is a critical security feature - changes require careful testing
-- Cross-seed integration allows keeping torrents that are actively seeding
-- Real-time updates use **SignalR** - maintain websocket patterns when adding features
+- **Settings dirty tracking** uses JSON snapshot comparison (`buildSnapshot()` + `hasPendingChanges()`)
