+"""
+ManagerBase -- private common base of the seven manager ABCs.
+
+Before this module, the constructor and the AuthProtocol sanity check were
+copy-pasted into every manager file (seven copies of the same 15 lines, the
+same warning text). One copy now lives here.
+
+Private on purpose (leading underscore, not exported from
+managers/__init__.py): providers subclass ChannelManager, VodManager and
+so on, never ManagerBase itself.
+
+Constructor contract (unchanged from the per-file versions)
+-----------------------------------------------------------
+Four required keyword-only collaborators. No **kwargs: a typo at a call
+site becomes an immediate TypeError. Subclasses that need extra state
+declare additional keyword-only args, call super().__init__ with ONLY the
+four required ones, and store the extras on self afterwards.
