FIELD 04 / FAILURE REPORT
The parser failed open
Malformed structured output appeared in the interface as raw text.
Situation
A convenience fallback rendered the model response when schema validation failed during a demo.
Finding
The fallback bypassed both the response contract and the reviewer cues that depended on validated fields.
Response
- Remove raw fallback
- Return typed failure
- Preserve diagnostic record
- Add malformed-output tests
ARCHITECTURE LESSONA parser failure is a product state. Hiding it behind fluent text removes the safety boundary.
