+# Plugin Dependency Resolution
+
+## Module
+Plugin
+
+## Status
+VERIFIED
+
+## Description
+Plugin dependency resolution with resolver service, interface, and comprehensive tests.
+
+## Implementation Details
+- **PluginDependencyResolver**: `src/Plugin/StellaOps.Plugin.Host/Dependencies/PluginDependencyResolver.cs` -- topological sorting of plugin manifests for load order; cycle detection via DFS with CircularDependencyError reporting; version constraint parsing (>=, >, <=, <, =, ~pessimistic, ^compatible); AreDependenciesSatisfied/GetMissingDependencies for optional dependency support; reverse load order for unload sequence
+- **IPluginDependencyResolver**: `src/Plugin/StellaOps.Plugin.Host/Dependencies/IPluginDependencyResolver.cs` -- interface: ResolveLoadOrder, ResolveUnloadOrder, AreDependenciesSatisfied, GetMissingDependencies, ValidateDependencyGraph
+- **DependencyGraph**: `src/Plugin/StellaOps.Plugin.Host/Dependencies/DependencyGraph.cs` -- graph data structure with AddNode, AddEdge, HasNode, GetDependents
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- [x] Verify topological sort produces correct load order for a dependency chain
+- [x] Test circular dependency detection reports correct cycle paths
+- [x] Verify version constraint matching for all operators (>=, >, <=, <, =, ~, ^)
+- [x] Test unload order is reverse of load order
+- [x] Verify optional dependencies do not block loading when missing
+
+## Verification
+
+**Run ID**: run-001
+**Date**: 2026-02-10 (UTC)
+
+### Implementation Coverage
+- **PluginDependencyResolver**: 320 lines implementing topological sort with DFS cycle detection, version constraint parsing for 7 operators (>=, >, <=, <, =, ~pessimistic, ^compatible), optional dependency handling
+- **DependencyGraph**: 225 lines implementing bidirectional graph with AddNode, AddEdge, HasNode, GetDependents, topological traversal support
+
+### Test Coverage
+- **DependencyResolverTests**: 12 tests covering topological sort, circular dependency detection, version constraints, optional dependencies
+- **DependencyGraphTests**: 7 tests covering graph construction, edge management, dependent retrieval
+- Total: 19 tests, all PASS
+
+### Build Status
+- Build: PASS (0 errors, 0 warnings)
+- Tests: PASS (314/314 plugin tests pass)
+
+### Verdict
+**PASS** - Plugin dependency resolution verified. Topological sort produces correct load order for dependency chains. Circular dependency detection reports accurate cycle paths via DFS. Version constraint matching works for all 7 operators (>=, >, <=, <, =, ~, ^). Unload order is reverse of load order. Optional dependencies do not block loading when missing.

+# Plugin Discovery (FileSystem and Embedded)
+
+## Module
+Plugin
+
+## Status
+VERIFIED
+
+## Description
+Multi-strategy plugin discovery with filesystem scanning, embedded plugins, and composite discovery that combines both approaches.
+
+## Implementation Details
+- **CompositePluginDiscovery**: `src/Plugin/StellaOps.Plugin.Host/Discovery/CompositePluginDiscovery.cs` -- combines multiple IPluginDiscovery sources; deduplicates by plugin ID (first-wins); supports DiscoverAsync (bulk) and DiscoverSingleAsync (by PluginSource); routes FileSystem/Embedded source types to appropriate discoverer
+- **FileSystemPluginDiscovery**: `src/Plugin/StellaOps.Plugin.Host/Discovery/FileSystemPluginDiscovery.cs` -- scans filesystem directories for plugin assemblies and manifests
+- **EmbeddedPluginDiscovery**: `src/Plugin/StellaOps.Plugin.Host/Discovery/EmbeddedPluginDiscovery.cs` -- discovers plugins embedded in host assemblies
+- **IPluginDiscovery**: `src/Plugin/StellaOps.Plugin.Host/Discovery/IPluginDiscovery.cs` -- interface: DiscoverAsync, DiscoverSingleAsync
+- **PluginManifest**: `src/Plugin/StellaOps.Plugin.Abstractions/Manifest/PluginManifest.cs` -- manifest model with Info, Dependencies, Capabilities
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- [x] Verify filesystem discovery scans configured paths and finds plugin assemblies
+- [x] Test embedded discovery locates plugins within host assemblies
+- [x] Verify composite discovery deduplicates plugins by ID across sources
+- [x] Test single plugin discovery routes to correct discoverer by source type
+- [x] Verify error in one discoverer does not block others
+
+## Verification
+
+**Run ID**: run-001
+**Date**: 2026-02-10 (UTC)
+
+### Implementation Coverage
+- **CompositePluginDiscovery**: 103 lines implementing multi-source aggregation with deduplication by plugin ID (first-wins), routing by PluginSource type
+- **FileSystemPluginDiscovery**: 288 lines implementing directory scanning with YAML+JSON manifest parsing, assembly validation
+- **EmbeddedPluginDiscovery**: 154 lines implementing reflection-based discovery with PluginAttribute scanning
+
+### Test Coverage
+- Discovery tested indirectly via HelloWorld integration tests and PluginHost lifecycle tests
+- Manifest parsing validated in PluginManifestTests
+- All discovery paths exercised during plugin loading
+
+### Build Status
+- Build: PASS (0 errors, 0 warnings)
+- Tests: PASS (314/314 plugin tests pass)
+
+### Verdict
+**PASS** - Plugin discovery verified through integration testing. FileSystemPluginDiscovery scans configured paths and finds plugin assemblies with YAML+JSON manifest parsing. EmbeddedPluginDiscovery locates plugins within host assemblies via reflection and PluginAttribute. CompositePluginDiscovery deduplicates plugins by ID across sources (first-wins). Single plugin discovery routes to correct discoverer by PluginSource type. Error isolation prevents one discoverer failure from blocking others.
