Constant KTSTR_LOCK_DIR_ENV 

pub const KTSTR_LOCK_DIR_ENV: &str = "KTSTR_LOCK_DIR";

Name of the environment variable that overrides ktstr’s flock directory for inter-process resource locking (cpuset / LLC reservation locks). Empty / unset falls back to the hardcoded /tmp default at crate::cache::resolve::resolve_lock_dir (the literal string, not std::env::temp_dir() / TMPDIR resolution — historical default kept for stability). Used by tests + CI environments that need isolated lock-dirs.
