Constant HISTORY_TRIM_BREADCRUMB_CANONICAL 

pub const HISTORY_TRIM_BREADCRUMB_CANONICAL: &'static str;

Canonical breadcrumb text used for trim markers. This is the English string that has been stable across all locales; it is the locale- independent anchor for legacy migration. Injected breadcrumbs are always produced via get_required_cli_string("history-trim-breadcrumb"), which currently resolves to this same English text in every locale. Checking the canonical value makes restore independent of the current process locale.
