//! The ctx budget line lives on the settled step-group chrome ONLY (#1842).
//!
//! Discord used to append the ctx footer to every answer message: the final
//! post carried it inline on the last chunk (or as its own chunk), the
//! kept-intermediate dedup path edited it into the kept message via
//! edit_message, and the settled line showed it again — every turn displayed
//! the budget twice, and the completion message dragged a token count under
//! prose nobody asked for it on. #1841 gave the budget its home on the flow
//! group; this pins the answer messages clean, matching Telegram and the
//! Slack #1806 shape.
//!
//! Source-scan sentinels: the delivery paths are network calls
//! (send_message / edit_message against a live Discord session), so the
//! regression guard is lexical. If a footer-on-answer attachment sneaks
//! back into `handler.rs`, these fail before CI does.
