# Phase 6 Implementation: Marketplace and Monitoring

## Delivered Marketplace scope
- Added marketplace workflow and command factory:
  - `MarketplaceWorkflowService`
  - `MarketplaceCommandFactory`
- Added marketplace controller:
  - Catalog browsing endpoint
  - Plugin install/update/remove endpoints
- Added routes:
  - `GET /api/v1/plugin-market`
  - `POST /api/v1/plugins/install`
  - `POST /api/v1/plugins/update`
  - `POST /api/v1/plugins/remove`
- Added command types:
  - `PLUGIN_INSTALL`
  - `PLUGIN_UPDATE`
  - `PLUGIN_REMOVE`

## Delivered Monitoring scope
- Added monitoring controller:
  - `GET /api/v1/metrics/servers/{serverId}/live`
  - `POST /api/v1/alerts/rules`
  - `GET /api/v1/alerts`
- Added ingest controller:
  - `POST /api/v1/metrics/ingest`

## Architecture notes
- Marketplace lifecycle operations are routed through the same command orchestration contract as other platform operations.
- Monitoring includes both pull-oriented live endpoint patterns and push-oriented ingest patterns for agent collectors.
