# Phase 4 Implementation: Hosting MVP Runtime Wiring

## Delivered
- Site/domain/SSL controllers now delegate to a single workflow service.
- Hosting command envelopes are generated through `HostingCommandFactory`.
- Webserver profile normalization supports:
  - `nginx`
  - `apache` (`httpd` alias)
  - `openlitespeed` (`ols` alias)
- Command orchestrator now accepts:
  - `DOMAIN_ADD`
  - `DOMAIN_REMOVE`
  - `WEBSERVER_RELOAD`

## Runtime flow
1. API receives request for site/domain/ssl mutation.
2. `SiteWorkflowService` validates and maps request to typed command envelope.
3. `CommandOrchestrator` assigns job metadata and enqueues dispatch payload.
4. Execution plane consumes command and performs adapter-specific operation.

## Notes
- This phase intentionally keeps persistence minimal while making runtime wiring explicit.
- Next step is adding provider-specific validation templates and dry-run checks before dispatch.
