fn set(&self, key: &str, value: PortValue) -> Result<(), SdkError>

Set a value at runtime (in-memory layer). Persistence is impl-defined.

fn list(&self) -> Result<Vec<(String, PortValue)>, SdkError>

List all keys (for diagnostics, dumping, validation).

fn source(&self, _key: &str) -> Option<String>

Returns the layer that supplied a key, for diagnostics.
