//! ChanFix helps recover an opless channel. The engine continuously scores
//! op-time per identity from live network state; ChanFix reads those scores to
//! reop the channel's trusted regulars. It **defers to ChanServ**: a registered
//! channel is ChanServ's job, so ChanFix refuses to touch one. Operator-only.
//!
//! SCORES <#channel> shows the standings; CHANFIX <#channel> performs the fix.
//! `lib.rs` holds the dispatcher; each command lives in its own file.
