tix-tracker 0.12.0

//! Integration tests for the `tix::assignee` module, driving the compiled
//! library with a fake `git` on `PATH` — never real git.
//!
//! The tests point the resolver's program seam at an absolute fake executable,
//! avoiding process-global `PATH` mutation while still exercising the same
//! subprocess behavior `git_identity()` uses.
