"""Operational smoke test against the *running web process* (ADR-0016).

Different in kind from every other test in this repo. Everything else drives
the app in-process through `ASGITransport`; this drives a real uvicorn process
over a real socket, backed by the Docker Compose stack, after the two
deployment steps (`alembic upgrade head`, `src.cli.qdrant_bootstrap`) have run
for real. ADR-0016 reserves Compose for exactly this: "manual local validation
and a later, serialized operational smoke test of the running web process",
run "as a serialized pre-release or scheduled gate".

It is therefore **skipped unless `SMOKE_BASE_URL` is set**, so a plain
`uv run pytest` never touches Docker Compose. Run it through `scripts/smoke.sh`,
which brings the stack up, provisions a tenant, starts the process, and exports
the environment below.

Because the app runs in its own process, this is also the only place in the
suite where the real `configure_logging()` is in effect --
`tests/conftest.py::_no_real_logging_configuration` no-ops it everywhere else
to keep global structlog state out of other tests. So the ADR-0011 log sink is
asserted here and nowhere else.
