+# CLI Command Router Infrastructure
+
+## Module
+Cli
+
+## Status
+IMPLEMENTED
+
+## Description
+Foundation infrastructure for CLI command consolidation including a route-based command router, JSON-driven route mapping (60+ mappings), command group builder for hierarchical command trees, and deprecation warning system.
+
+## Implementation Details
+- **Infrastructure**: `src/Cli/StellaOps.Cli/Infrastructure/` -- command router, route resolver, deprecation middleware
+- **Route Mapping**: `src/Cli/StellaOps.Cli/cli-routes.json` -- JSON file with 60+ route mappings defining old->new command paths, deprecation versions, and reasons
+- **Command Factory**: `src/Cli/StellaOps.Cli/Commands/CommandFactory.cs` -- hierarchical command tree builder using route mappings
+- **Sprint**: SPRINT_20260118_010_CLI_consolidation_foundation
+- **Architecture**:
+  - Route-based command router intercepts old command paths and redirects to new consolidated paths
+  - Each mapping has `old` path, `new` path, `type` (deprecated), `removeIn` version, and `reason`
+  - Supports settings consolidation (Sprint 011), verification consolidation (Sprint 012), and scanning consolidation (Sprint 013)
+- **Tests**: `src/Cli/__Tests/StellaOps.Cli.Tests/Infrastructure/CommandRouterTests.cs`
+
+## E2E Test Plan
+- [ ] Verify all 60+ route mappings correctly redirect old commands to new paths
+- [ ] Verify deprecation warnings are emitted on stderr for deprecated command paths
+- [ ] Verify new command paths work without deprecation warnings
+- [ ] Verify command tree hierarchy is properly built from route mappings
+- [ ] Verify `--help` on deprecated commands shows migration guidance
+- [ ] Verify route resolver handles unknown commands gracefully with error message
+- [ ] Verify route mapping JSON is valid and parseable at startup
