A write that leaves out a required field saves again

Yesterday's check that content fits its type was meant to say nothing about a write that simply leaves a required field out — that is what a partial save looks like, and it was never the thing the check was built to catch.

It said something anyway. A save whose content omitted a field the type marks as required came back with the serializer's own words — "JSON deserialization for type … was missing required properties including: 'content'" — in English, whatever language you read the portal in, and the save did not happen. Assistants writing to a node through the mesh tools hit it first, because a partial update is their ordinary shape.

Those writes land again, exactly as they did before the check existed. Content in which nothing matches the type is still refused, and still says so in your language, naming the fields — that part was and remains the point of the check.
