+"""Phase 10 (Track D.3) stub-end-to-end fixture: Python + HTTP.
+
+The verifier publishes:
+
+* ``NYX_HTTP_ENDPOINT`` — `http://127.0.0.1:{port}` the HttpStub listens on.
+* ``NYX_HTTP_LOG``      — companion log path the harness appends attempted
+  outbound calls to so the host HttpStub picks them up on
+  ``drain_events()`` even when the request bypasses the on-the-wire
+  listener (DNS-mocked, network-isolated sandbox, pre-flight check).
+
+This fixture exercises the side-channel path: it records an attempted
+SSRF call to ``http://169.254.169.254/latest/meta-data/`` through the
+Python shim helper ``__nyx_stub_http_record`` without issuing the
+actual network call.  The companion test in
+``tests/stubs_e2e_per_lang.rs`` splices in
+``crate::dynamic::lang::python::probe_shim`` ahead of this source, runs
+it with both env vars set, and asserts the stub captured the attempt.
