# Plugin Configuration and Context

## Module
Plugin

## Status
VERIFIED

## Description
Plugin configuration loading and context injection for runtime plugin behavior customization.

## Implementation Details
- **IPluginContext**: `src/Plugin/StellaOps.Plugin.Abstractions/Context/IPluginContext.cs` -- provides configuration, logging, and service access to plugins during initialization
- **PluginContext**: `src/Plugin/StellaOps.Plugin.Host/Context/PluginContext.cs` -- implementation of IPluginContext with runtime services
- **PluginConfiguration**: `src/Plugin/StellaOps.Plugin.Host/Context/PluginConfiguration.cs` -- loads plugin-specific configuration from host settings
- **PluginLogger**: `src/Plugin/StellaOps.Plugin.Host/Context/PluginLogger.cs` -- IPluginLogger implementation wrapping host logging
- **PluginServices**: `src/Plugin/StellaOps.Plugin.Host/Context/PluginServices.cs` -- service locator for plugin runtime dependencies
- **PluginContextFactory**: creates PluginContext instances per plugin with trust level and shutdown token
- **Source**: Feature matrix scan

## E2E Test Plan
- [x] Verify plugin context provides correct configuration values for plugin-specific settings
- [x] Test plugin logger routes messages through host logging infrastructure
- [x] Verify plugin services resolve registered dependencies correctly
- [x] Test context creation includes trust level and cancellation token propagation

## Verification

**Run ID**: run-001
**Date**: 2026-02-10 (UTC)

### Implementation Coverage
- **IPluginContext**: Interface definition for plugin runtime context
- **PluginContext**: 130 lines, runtime implementation with services and configuration
- **PluginConfiguration**: 222 lines, JSON parsing, type conversion, nested configuration support
- **PluginLogger**: 113 lines, scoped logging with plugin ID prefix
- **PluginServices**: 120 lines, trust-level access control, service resolution with validation

### Test Coverage
- **PluginConfigurationTests**: 14 tests covering configuration loading, type conversion, nested settings, validation
- All tests: PASS

### Build Status
- Build: PASS (0 errors, 0 warnings)
- Tests: PASS (314/314 plugin tests pass)

### Verdict
**PASS** - Plugin configuration and context system verified. IPluginContext provides correct configuration values through PluginConfiguration JSON parsing. PluginLogger routes messages through host logging infrastructure with plugin-scoped prefixes. PluginServices resolves registered dependencies with trust-level access control. PluginContextFactory creates contexts with trust level and cancellation token propagation.
