Documentation    Regression guard tests for bug #647 - Container.resolve() crash
...              Three CLI commands (plan tree, plan explain, plan correct)
...              are regression-guarded after the historical
...              Container.resolve() crash was fixed.
...
...              These tests use a REAL DI container (not MagicMock).
...              Existing M3 tests missed this class of issue because
...              they mock get_container() with MagicMock which auto-creates
...              any attribute.
...
...              NOTE: Bug #647 appears fixed; these tests now run as normal
...              regression checks for correct command behavior.
