Served writes now refuse, before changing the state: - a document write with members or JSON types its plan did not accept (the same body check entity writes use), or at a path other than the one the state holds the document at; - a body or resulting value data/add would refuse (a number inexact as data/get writes it, a __proto__ member, nesting past the limit), so data/get output always loads back, increments included; - a create, update or document write that would take the state past the 32 MiB data/add intake limit (resource_constraint), with the state's serialized size kept incrementally rather than reserialized.
