# Integration Doctor Checks (Connectivity, Credentials, Permissions, Rate Limits)

## Module
Integrations

## Status
IMPLEMENTED

## Description
Doctor diagnostic checks for integration health: connectivity verification, credential validation, permission checks, and rate limit status monitoring. Generates aggregated health reports across all integrations.

## Implementation Details
- **Integration service**: `src/Integrations/StellaOps.Integrations.WebService/IntegrationService.cs` -- health check orchestration across all integrations
- **Infrastructure abstractions**: `src/Integrations/StellaOps.Integrations.WebService/Infrastructure/Abstractions.cs` -- connectivity, credential, permission check interfaces
- **Integration models**: `src/Integrations/__Libraries/StellaOps.Integrations.Core/IntegrationModels.cs` -- health report models
- **Plugin contract**: `src/Integrations/__Libraries/StellaOps.Integrations.Contracts/IIntegrationConnectorPlugin.cs` -- plugins implement health check methods
- **API endpoints**: `src/Integrations/StellaOps.Integrations.WebService/IntegrationEndpoints.cs` -- health check API
- **Doctor plugin integration**: Cross-module with `src/Doctor/` -- Doctor integration checks reference integration health
- **Tests**: `src/Integrations/__Tests/StellaOps.Integrations.Tests/IntegrationServiceTests.cs`
- **Source**: SPRINT_20260110_102_006_INTHUB_doctor_checks.md

## E2E Test Plan
- [ ] Verify connectivity checks detect unreachable integrations
- [ ] Test credential validation catches expired or invalid credentials
- [ ] Verify permission checks identify missing API scopes
- [ ] Test rate limit monitoring reports quota usage
- [ ] Verify aggregated health report covers all configured integrations
