Function validate_can_commit 

pub fn validate_can_commit(
    config: &Config,
    registry: &AgentRegistry,
    developer_agent: &str,
    reviewer_agent: &str,
    config_path: &Path,
) -> Result<()>

Arguments

• config - The pipeline configuration
• registry - The agent registry
• developer_agent - Name of the developer agent
• reviewer_agent - Name of the reviewer agent
• config_path - Path to the unified config file for error messages

Returns

Returns Ok(()) if validation passes, or an error with details.
