//! Binary distribution adapter: `manual` / GitHub Releases.
//!
//! Attaches prebuilt binaries to a GitHub Release (`gh release`). GitHub
//! Releases are not observable through the
//! [`RegistryQuery`](crate::ports::RegistryQuery) port, so `verify` returns
//! [`VerifyOutcome::Unknown`] **explicitly** (ADR-0002 §1) — an honest "cannot
//! check", never a false `Missing`.
