supercode-cli 0.4.16

//! BP-9 (Domain 6, config surface): real-binary coverage for the launch-time
//! config layers and the surfaces that report on them.
//!
//! Everything here drives the shipped `supercode` binary, because every one
//! of these rows is a claim about what happens when a user runs the tool —
//! a unit test of the resolver proves the resolver, not the CLI's use of it.
//! No test reaches the network: the one release-check case points the check
//! at a closed local port.
