Welcome to `outcome <https://github.com/python-trio/outcome>`__!

Capture the outcome of Python function calls. Extracted from the
`Trio <https://github.com/python-trio/trio>`__ project.

## AI interpretation — verify before relying

Captures the outcome of Python function calls as either a success value or an exception, providing a structured way to handle and propagate results without raising.

Verdict: Stable, well-maintained utility for structured result handling extracted from the Trio async framework. No known vulnerabilities, permissive dual licensing, and minimal dependencies make it a low-risk addition. The aging maintenance status reflects infrequent updates rather than abandonment—appropriate for a mature, focused library.
