+# Forward proxy fixture
+
+`ProxyFixture` runs an in-process forward proxy so the proxy lane needs no external service.
+
+| Factory | Behaviour |
+|---|---|
+| `ProxyFixture.openProxy()` | accepts CONNECT and tunnels to the target |
+| `ProxyFixture.authenticatingProxy(user, password)` | answers `407` until `Proxy-Authorization` matches |
+
+The fixture records every request line and every `Proxy-Authorization` value it saw, which is what
+lets the suite prove design §24.3: proxy credentials never appear on the target request, and a proxy
+CONNECT failure is reported as `HttpProxyException` rather than as a target TLS failure.
