## Summary

stitch-pty is described as a cross-platform, async pseudo-terminal library for Python with integrated terminal emulation, implemented in Rust with Python bindings. The research flagged it as a young project it could not independently verify further.

## Key findings

- Claims cross-platform support (notably including Windows, unlike the stdlib `pty` module), unlike every other option surveyed in this subject.
- Implemented in Rust with bindings — a compiled-extension dependency, not a pure-Python one.

## Pros / strengths

- If its claims hold up, it would solve the Windows-support gap that every stdlib-`pty`-based approach (including `tai_test.py`'s own) has.

## Cons / limitations / caveats

- Explicitly flagged during research as young and unverified — no maturity signal (adoption, release history, test coverage) was found or checked.
- A compiled Rust extension is a real dependency, directly in tension with `tai.py`'s own zero-dependency, pure-stdlib project constraint that `tai_test.py` was built to respect.

## Relevance to tai

Surveyed and explicitly not adopted, for two independent reasons: insufficient verified maturity, and a hard conflict with the project's stdlib-only constraint. `tai_test.py` built its pty support directly on the stdlib `pty` module instead, accepting the resulting Windows limitation (POSIX-only, `pty` module is not available on Windows) as the simpler, dependency-free tradeoff.
