+# Local Validator for Offline Config Checking
+
+## Module
+Cli
+
+## Status
+VERIFIED
+
+## Description
+Offline local validator that checks stella.yaml configuration files without requiring server connectivity, enabling developers to validate configs before committing.
+
+## Implementation Details
+- **Validation Module**: `src/Cli/StellaOps.Cli/Validation/` -- offline validation infrastructure
+- **Command Group**: `src/Cli/StellaOps.Cli/Commands/ConfigCommandGroup.cs` -- config validation under config commands
+- **Commands**:
+  - `stella config validate` / `stella config validate-yaml <path>` -- validate stella.yaml configuration offline
+- **Validation checks**: schema compliance, required fields, value ranges, cross-field consistency
+
+## E2E Test Plan
+- [ ] Run `stella config validate ./stella.yaml` and verify validation passes for valid config
+- [ ] Run with invalid config and verify validation errors reported with line numbers
+- [ ] Verify validation works without network connectivity (offline)
+- [ ] Verify schema compliance checks for all required fields
+- [ ] Verify value range validation (e.g., port numbers, timeout values)
+- [ ] Verify cross-field consistency checks
