• assert get_environment_proxies mounts IPv4 as all://<ip>, IPv6 as all://[<ip>], and localhost as all://localhost without wildcard asterisk
• assert httpx.Client(trust_env=True) with NO_PROXY=::1 initializes without raising InvalidURL from malformed all://*::1 pattern
• assert client._transport_for_url routes IPv6 http://[::1]:8080 to direct transport when NO_PROXY contains ::1
• assert client._transport_for_url routes exact IPv4 http://127.0.0.1:8080 to direct transport when NO_PROXY contains 127.0.0.1
• assert client._transport_for_url routes attacker.example.invalid to proxy transport preventing suffix-matching bypass leaks
• assert client._transport_for_url routes not-localhost.example.invalid to proxy transport preventing suffix-matching bypass leaks
