Detailed Description

The plain data a derived change is made of. This header includes nothing of the registry or the forms layer, so the wire types can use it.

kMaxChangeKeys

std::size_t morph::effects::kMaxChangeKeys = 4096

inlineconstexpr

The most keys one RecordChange carries.

The wire readers refuse a record entry with more keys, so a producer never emits one: a change that would name more rows is reported as a whole-type change (keys absent), which over-notifies but never misses. The bound keeps one peer-supplied list from forcing an unbounded allocation.
