# Advisory Source Management CLI (stella sources list/check/enable/disable/status)

## Module
Cli

## Status
IMPLEMENTED

## Description
Manage advisory data sources: list by category (primary/distro/ecosystem/scoring), check connectivity, enable/disable sources, and view detailed source status.

## Implementation Details
- **Command Group**: `src/Cli/StellaOps.Cli/Commands/Sources/` -- advisory source management commands
- **Command Handlers**: `src/Cli/StellaOps.Cli/Commands/CommandHandlers.cs` -- partial class with source-related handlers
- **Config consolidation**: Sources commands are consolidated under `stella config sources` via route mapping in `src/Cli/StellaOps.Cli/cli-routes.json` (old: `sources list` -> new: `config sources list`)
- **Commands**:
  - `stella config sources list` -- list advisory sources filtered by category (primary, distro, ecosystem, scoring)
  - `stella config sources check` -- verify connectivity to configured advisory sources
  - `stella config sources enable <source>` -- enable a specific advisory source
  - `stella config sources disable <source>` -- disable a specific advisory source
  - `stella config sources status` -- show detailed status for all configured sources
- **Config Group**: `src/Cli/StellaOps.Cli/Commands/ConfigCommandGroup.cs` -- `ConfigCommandGroup` hosts the sources subcommand
- **Config Catalog**: `src/Cli/StellaOps.Cli/Commands/ConfigCatalog.cs` -- catalog of configuration items including sources

## E2E Test Plan
- [ ] Run `stella config sources list` and verify sources listed with name, category, enabled status
- [ ] Run `stella config sources list --category distro` and verify only distro sources shown
- [ ] Run `stella config sources check` and verify connectivity status for each source
- [ ] Run `stella config sources enable nvd` and verify source is enabled
- [ ] Run `stella config sources disable nvd` and verify source is disabled
- [ ] Run `stella config sources status` and verify detailed status including last sync, error counts
- [ ] Verify deprecated alias `stella sources list` still works and shows deprecation warning
- [ ] Run with `--format json` and verify valid JSON output
- [ ] Verify exit code is non-zero when connectivity check fails
