Type Alias SourceFactory 

pub type SourceFactory = Arc<dyn Fn(Value) -> CliResult<Box<dyn Source>> + Send + Sync>;

A factory that builds a Source trait object from its JSON/YAML config (source.config). This is the extension point third-party connectors plug into: a custom-CLI author registers one per connector type: they want their faucet binary to understand.

The factory is synchronous — a connector that needs to connect eagerly should do so lazily on first use (the pattern every built-in file/DB connector already follows). Return a typed error (wrap your own error in faucet_core::FaucetError::Custom) on invalid config.
