Stackmap 0.1.0-alpha.* supports macOS 15 or newer on Apple Silicon (arm64)
and Intel (x86_64). CI runs the complete Rust 1.88.0 suite natively on the
explicit macos-15 and macos-15-intel GitHub runners. A smaller current-stable
lane catches forward incompatibility without changing the release toolchain.
Terminal.app on macOS 15 is the reference interactive environment. Deterministic
render and PTY tests cover key decoding, minimum-width behavior, cleanup, and
portable J/K and g/G fallbacks. Those tests do not certify every terminal
brand; other terminals are best effort and may intercept modifier keys.
Other Unix systems are unsupported during the alpha. Core rendering and Git reads may work, but macOS open/copy integration and release artifacts are not provided for them.
Git is required. Graphite CLI metadata and authenticated GitHub CLI are optional. Provider failures degrade explicitly while all Git-local branches remain available. See graphite-compatibility.md for the characterized Graphite boundary.
Only the newest alpha receives fixes. Report ordinary defects through the sanitized bug form and vulnerabilities through private reporting described in SECURITY.md.
