Thanks, fixed the typo!

I don't understand what do you mean by "all writes are considered non-conflicting" in standard equality policies. … I also don't get how custom merge should report a failure. By returning null? But what if the mutable state type is nullable and we want to succeed with null result.

I am not sure of the answer to this unfortunately. Since the default return value is null, and in that case conflicting writes do fail, the wording "all writes are non-conflicting" is definitely confusing. I'll dig into this a bit more and try to clarify.
