+# Connector Runtime with Resilience Patterns (Circuit Breaker, Retry, Rate Limiting, Pooling)
+
+## Module
+Integrations
+
+## Status
+VERIFIED
+
+## Description
+Connector runtime managing connector instantiation, connection pooling, retry with exponential backoff, circuit breaker for fault isolation, and per-integration rate limiting. Handles both built-in and plugin connectors uniformly via ConnectorFactory.
+
+## Implementation Details
+- **Integration service**: `src/Integrations/StellaOps.Integrations.WebService/IntegrationService.cs` -- connector runtime managing instantiation and lifecycle
+- **Plugin loader**: `src/Integrations/StellaOps.Integrations.WebService/IntegrationPluginLoader.cs` -- dynamic loading of built-in and plugin connectors
+- **Infrastructure abstractions**: `src/Integrations/StellaOps.Integrations.WebService/Infrastructure/Abstractions.cs` -- circuit breaker, retry, rate limiting interfaces
+- **Default implementations**: `src/Integrations/StellaOps.Integrations.WebService/Infrastructure/DefaultImplementations.cs` -- resilience pattern implementations
+- **Plugin contract**: `src/Integrations/__Libraries/StellaOps.Integrations.Contracts/IIntegrationConnectorPlugin.cs` -- unified connector interface
+- **Integration DTOs**: `src/Integrations/__Libraries/StellaOps.Integrations.Contracts/IntegrationDtos.cs` -- connector data transfer objects
+- **API endpoints**: `src/Integrations/StellaOps.Integrations.WebService/IntegrationEndpoints.cs` -- connector management API
+- **Tests**: `src/Integrations/__Tests/StellaOps.Integrations.Tests/IntegrationServiceTests.cs`, `IntegrationPluginLoaderTests.cs`
+- **Source**: SPRINT_20260110_102_002_INTHUB_connector_runtime.md
+
+## E2E Test Plan
+- [ ] Verify circuit breaker isolates failed connectors
+- [ ] Test retry with exponential backoff recovers from transient failures
+- [ ] Verify per-integration rate limiting prevents API quota exhaustion
+- [ ] Test connection pooling reuses connections efficiently
+- [ ] Verify ConnectorFactory handles both built-in and plugin connectors
