# Exempt paths are relative to the scan path, which must be the crate root: `external_deps`
# reads `Cargo.toml` there, and scanning `src` instead silently stops flagging every
# external-crate reach.

# The provisioning lock's test spawns two real threads and holds the critical section with a
# 50ms sleep: concurrency *is* the subject, so a double would prove nothing, and dropping the
# sleep narrows the race window until a lock-less implementation can pass by luck. Whole-file
# because line-scoped exemptions apply only to `coverage` and `mutation`.
