"""The model call — a stand-in. Provided; do not edit.

Flagship F1 swaps this for a real client. It logs through a CHILD logger, ``askcli.backend``,
on purpose: this function never receives a request id, yet its line must carry the right one.
That only works if the id travels in a ``contextvars.ContextVar`` that the formatter reads —
not as an argument, and not in a module-level global.
