+"""Phase 10 (Track D.3) stub-end-to-end fixture: Python + SQL.
+
+The verifier publishes:
+
+* ``NYX_SQL_ENDPOINT`` — absolute path of a SQLite DB the SqlStub owns.
+* ``NYX_SQL_LOG``      — companion log path the harness appends executed
+  queries to so the host SqlStub picks them up on ``drain_events()``.
+
+This fixture exercises both: it opens the stub DB with stdlib ``sqlite3``,
+runs a tautology SELECT (``OR 1=1``), and forwards the executed query to
+the stub through the Python shim helper ``__nyx_stub_sql_record``.  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 tautology.
