Module executor 

Sync Executor - Domain logic for ggen sync command

This module contains the business logic for the sync pipeline, extracted from the CLI layer to maintain separation of concerns.

The executor handles:

• Manifest parsing and validation
• Validate-only mode
• Dry-run mode
• Full sync pipeline execution

Architecture

The CLI verb function should be thin (complexity <= 5):

1. Parse CLI args into SyncOptions
2. Call SyncExecutor::execute(options)
3. Return result

All business logic lives here in the executor.
