Constant INCLUDE_EOL_HELP 

pub const INCLUDE_EOL_HELP: &str = "Include end-of-life stable series when \
     expanding a `START..END` kernel range. Default range resolution draws \
     only from kernel.org's active releases (releases.json), which omits \
     series no longer maintained; with this flag the range additionally \
     covers every `vX.Y.Z` tag in the gregkh linux-stable mirror, so an EOL \
     series inside [START, END] still contributes its highest point release. \
     Has no effect on a single version, path, cache key, or git source — \
     only range expansion consults the EOL set. When the mirror tag list \
     cannot be fetched, expansion proceeds with a warning against the \
     active-release set alone.";

Help text for the --include-eol flag, shared by every command that expands a START..END kernel range (cargo ktstr test, coverage, llvm-cov, verifier, kernel list, and kernel build when the --kernel value is a range). One const so the wording stays identical across every surface the flag appears on.

Describes what the code DOES: crate::cli::expand_kernel_range draws only from kernel.org’s releases.json by default (active stable/longterm series); under this flag it unions in the vX.Y.Z tags of the gregkh linux-stable mirror (crate::fetch::cached_stable_tags) and takes the latest patch per (major, minor) series across both sources, so a series that has aged out of releases.json still contributes its highest point release. If the mirror tag list cannot be fetched, expansion proceeds with a warning against the active-release set alone.
