## Critical Rules
- **NEVER** edit: `/bin/`, `/obj/`, `/.git/`, `/.vs/`, `/packages/`, generated migration files
- **Security First**: All code changes must prioritize cryptographic integrity and data protection
- **Test Coverage**: New features require xUnit unit tests with NSubstitute mocking
- **Check CODEOWNERS requirements**: The repo has a `.github/CODEOWNERS` file to define team ownership for different parts of the codebase. Respect that code owners have final authority over their designated areas
- **NEVER** edit: `/bin/`, `/obj/`, `/.git/`, `/.vs/`, `/packages/` which are generated files
- **NEVER** use code regions: If complexity suggests regions, refactor for better readability
- **NEVER** compromise zero-knowledge principles: User vault data must remain encrypted and inaccessible to Bitwarden
- **NEVER** log or expose sensitive data: No PII, passwords, keys, or vault data in logs or error messages
- **ALWAYS** use secure communication channels: Enforce confidentiality, integrity, and authenticity
- **ALWAYS** encrypt sensitive data: All vault data must be encrypted at rest, in transit, and in use
- **ALWAYS** prioritize cryptographic integrity and data protection
- **ALWAYS** add unit tests (with mocking) for any new feature development
## Project Context
**Architecture**: CQRS pattern with feature-based organization
**Framework**: .NET 8.0, ASP.NET Core
**Database**: SQL Server primary, EF Core supports PostgreSQL, MySQL/MariaDB, SQLite
**Testing**: xUnit, NSubstitute
**Container**: Docker, Docker Compose, Kubernetes/Helm deployable

## Development Standards
## Project Structure
### CQRS Pattern
- Commands: `/src/Core/[Feature]/Commands/`
- Queries: `/src/Core/[Feature]/Queries/`
- Handlers implement `ICommandHandler<T>` or `IQueryHandler<T>`
### API Conventions
- RESTful endpoints with standard HTTP status codes
- Consistent error response: `{ "error": { "message": "..." } }`
- Pagination: `?skip=0&take=25`
- API versioning: `/api/v1/`
### Database Migrations
- **SQL Server**: Manual scripts in `/util/Migrator/DbScripts/`
- **Other DBs**: EF Core migrations via `pwsh ef_migrate.ps1`
- **Source Code**: `/src/` - Services and core infrastructure
- **Tests**: `/test/` - Test logic aligning with the source structure, albeit with a `.Test` suffix
- **Utilities**: `/util/` - Migration tools, seeders, and setup scripts
- **Dev Tools**: `/dev/` - Local development helpers
- **Configuration**: `appsettings.{Environment}.json`, `/dev/secrets.json` for local development
## Security Requirements
@@ -42,20 +34,39 @@
- **Validation**: Input sanitization, parameterized queries, rate limiting
- **Logging**: Structured logs, no PII/sensitive data in logs
## Common Commands
- **Build**: `dotnet build`
- **Test**: `dotnet test`
- **Run locally**: `dotnet run --project src/Api`
- **Database update**: `pwsh dev/migrate.ps1`
- **Generate OpenAPI**: `pwsh dev/generate_openapi_files.ps1`
## Code Review Checklist
- Security impact assessed
- xUnit tests added/updated
- xUnit tests added / updated
- Performance impact considered
- Error handling implemented
- Breaking changes documented
- CI passes: build, test, lint
- Feature flags considered for new features
- CODEOWNERS file respected
### Key Architectural Decisions
- Use .NET nullable reference types (ADR 0024)
- TryAdd dependency injection pattern (ADR 0026)
- Authorization patterns (ADR 0022)
- OpenTelemetry for observability (ADR 0020)
- Log to standard output (ADR 0021)
