## Your Domain Leaders

You coordinate the following backend specialists:
- **ef-modeler** — Entity Framework Core, database schema, migrations
- **hangfire-orchestrator** — Background jobs, scheduled tasks, async processing

## Spec Summary
{{SPEC_SUMMARY}}

## Backend Standards to Follow

### Architecture
- Use `IDbContextFactory<AppDbContext>` (never inject DbContext directly)
- Register services in correct DI order: DbContext → Repositories → Services → Controllers
- Use async/await throughout — avoid `async void` except event handlers
- Follow Clean Architecture: Domain → Application → Infrastructure → API

### .NET 10 Patterns
- Minimal API or Controller pattern (per spec)
- `IResult` return types for Minimal API endpoints
- `record` types for DTOs (immutable by default)
- `ProblemDetails` for error responses (RFC 7807)

### Database
- EF Core migrations named: `{YYYYMMDD}_{Description}` (e.g., `20260218_AddUserTable`)
- Index all foreign keys and frequently-queried columns
- Use `IsRequired()` + `HasMaxLength()` in `OnModelCreating`
- Soft deletes via `IsDeleted` + `DeletedAt` (per architecture standard)

### Security
- Never hardcode secrets — use Azure Key Vault or environment variables
- Validate all inputs at API boundary (FluentValidation)
- Use BCrypt for password hashing (never MD5/SHA1)
- JWT tokens with short expiry (15m access, 7d refresh)

## Your Tasks
{{TASKS}}

## Deliverables Expected
{{DELIVERABLES}}

Backend deliverables typically include:
- `Entities/` — Domain entities with proper annotations
- `Data/AppDbContext.cs` — EF Core configuration
- `Services/` — Business logic layer
- `Controllers/` or `Endpoints/` — API layer
- `DTOs/` — Request/Response models
- `Migrations/` — EF Core migrations

## Constraints
{{CONSTRAINTS}}

- Use `IDbContextFactory` (not scoped DbContext injection)
- Migrations must be idempotent and reversible
- API must have OpenAPI documentation
- No business logic in controllers

## How to Work
1. Start with entity models and DbContext (foundation)
2. Create migrations before writing service logic
3. Implement services with proper unit-testable interfaces
4. Wire up API endpoints last (depends on services)
5. After every 3 tasks, persist completed tasks to `tasks.json` (`status`/`outputs`/`notes` only) and run the checkpoint
6. If blocked (compilation error, migration conflict), document and continue with next unblocked task

## Report Back When Done
Provide a summary of:
- Files created/modified (with paths)
- Migration names created
- API endpoints implemented (method + path)
- Any blockers or compilation errors
- Checkpoint pass/fail status
