//! End-to-end coverage for the `mock.*` request-count gate (alef issue #443).
//!
//! The call site (`assertion_mock_capture::try_render_mock_capture_assertion`) and the
//! helper-definition gate (`fixtures_body.contains(capture.helper_name)` in
//! `test_file::render_test_file`) are tested SEPARATELY everywhere else in this codebase --
//! these tests drive the real `render_test_file` entry point so a fixture's call and the file's
//! helper definition land in ONE rendered artifact, the only way to catch the two disagreeing
//! about `capture.helper_name`. Mirrors `java::mock_capture_gate_tests` /
//! `kotlin::mock_capture_gate_tests`. ~keep
