     Returns:
-        dict: The ``blsKey`` record of ``futurePoolParams``, or an empty dict when there
-            is no pending update, or it carries no BLS key.

+            when there is no pending update, or it carries no BLS key.
 
     Note:
-        A pending update is reported as stake pool *parameters*, which carry the bare key
-        under ``blsKey``, while the active key is reported as pool *state* and carries the
-        key under ``spsBlsKey.bksKey`` together with its registration epoch. The epoch is
-        stamped only when the update takes effect, so the shallower nesting here is not
-        an oversight.
+        Both pending and active parameters are reported as pool state, with the key
+        under ``spsBlsKey.bksKey``. Return only the key record, without the registration
+        epoch reported alongside it.
