"""Tests for live auto-decompose settings resolution (issue #49638).

The gateway dispatcher used to capture ``kanban.auto_decompose`` once at boot,
so a user who flipped it to ``false`` to STOP runaway auto-decompose (which had
created and launched tasks they didn't intend) found the flag had no effect
without a full gateway restart. ``_resolve_auto_decompose_settings`` is now
called every tick, reading the current config.
