See the Shape, Then Ask Again

Give schema errors a little more context, and leave unverified parts visible.

Reviewing personal tool work from October 17, one small engineering change is worth recording: schema diagnostics can distinguish a document that is not an object from one missing required fields. They report only fixed-field presence and JSON types, without field values. A clearer outline makes the next debugging question more specific.

The source change has merged. A clear diagnostic need not print more data: first narrow the layer where a problem sits, then decide what to observe next.
