    No-op unless the test is marked `virtual_time`. Two kinds of reads are covered:

    - inline `time.time()` / `time.perf_counter()` -- redirected by patching the `time`
      module (these re-read the attribute at call time, so a scoped patch reaches them);
    - `default_factory=time.time` captured on event/chat-context models at import -- redirected
      by :func:`_patched_model_clocks`, since a module patch cannot reach a captured reference.

    Both resolve the loop at call time, so reads inside the loop see virtual time while any stray
    read from outside it (no running loop) falls back to a stable constant. Scoped to the test.
