Tessary malformed output

malformed_output is one of Tessary's built-in classifiers, a deterministic one: checks that pass or fail, no judgment involved. When a call site declares a structured output, Tessary captures its schema and validates each output against it.

It catches exactly the failure your calling code would hit in production: output that doesn't parse, or parses but violates the declared shape. Every firing is high confidence, since the output either matches the schema or it doesn't, and detections carry the violation messages as evidence. Where validation isn't meaningful, it stays quiet. Detections go to triage, where the ones ruled real issues become cases.
