+"""Orchestration test for ``multiple_adapters.main``.
+
+``main`` is thin glue, so we mock every collaborator and assert the wiring:
+which adapter runs, the schema/script calls, and the sentinel file write.
+
+LIMITATION: ``adapter_mode`` is a hardcoded local (= 0), so only the FHIR
+branch is reachable. The mode-1 (XML) and mode--1 (both) tests below are
+written but skipped — un-skip them once ``main`` accepts ``adapter_mode`` as
+a parameter or reads it from the environment. They document the intended
+behaviour and become live the moment the refactor lands.
