//! Canonical mapping of action names to the distro family they require.
//!
//! # Why this lives in `sysknife-core`
//!
//! Three components need to know which actions are family-specific:
//!
//! - `sysknife-brain` (`prompt.rs`) — per-distro prompt isolation.
//! - `sysknife-cli` (`distro_routing.rs`) — client-side routing guard.
//! - `sysknife-daemon` (`dispatcher.rs`) — the privileged execution fence.
//!
//! Keeping three hand-maintained copies caused the daemon fence to silently
//! drift out of parity with the authoritative prompt list, so a Debian-only
//! mutating action could reach a supported Fedora host without a family
//! mismatch being flagged. These constants are the **single source of truth**;
//! every consumer references them so the lists can never diverge again.
//!
//! When you add or rename a family-specific action, edit it here and nowhere
//! else.

/// Fedora-family action names that are NOT available on Debian-family distros.
///
/// These are rpm-ostree shaped actions.
