+    """Q10 (B01/ss07) ``dpFault`` (90) codes, from the ss07 fault spec.
+
+    ``dpFault`` is *overloaded*: several values are lifecycle/status rather than
+    errors (e.g. 400 = scheduled clean starting, 501 = returning to dock,
+    502 = recharge). A non-zero fault is not necessarily a blocking error.
+    The converse also holds: the device can sit in its error state (``dpStatus``
+    12) with ``dpFault`` still 0 (observed live with the dust-bin module
+    removed), so a ``None``/``NONE`` fault does not imply the absence of an
+    error condition.
+
+    These labels differ from the Q7 ``B01Fault`` for several shared numbers
+    (500, 501, 503, 569, 570) -- so this is a Q10-specific map, not a reuse of
+    ``B01Fault``. Codes marked "hw-confirmed" were observed firing live on a
+    physical ss07 in a context matching the label; the rest are from the spec
+    only, not yet observed live (single device).
