Module values 

Explicit environment and secret-command access supplied by the host.

Traits

ValueSource

Hosts choose which environment values and commands the runtime may access. Commands are disabled by default; the library never reads process env itself.

Functions

resolve_config_value

resolve_headers

resolve_template

Resolve a parsed template: any referenced env var that is unset ⇒ the whole value is None (pi semantics). Literal-only templates pass through as-is.
