## AI interpretation — verify before relying

Implements Happy Eyeballs (RFC 8305) connection establishment for asyncio when you already have resolved addresses, enabling fast failover between IPv4 and IPv6 without waiting for timeouts.

Verdict: Stable, actively maintained library in the top 100 PyPI packages with zero known vulnerabilities. Ideal for applications needing RFC 8305 Happy Eyeballs behavior when using pre-resolved addresses or alternative DNS methods; permissive PSF license and zero dependencies make adoption straightforward.
