Report #36977

[counterintuitive] Writing 'Output only valid JSON' and describing the schema in prose

Use native Structured Outputs \(JSON mode / function calling with schemas\) provided by the API.

Journey Context:
Prompting for JSON often led to markdown wrappers, missing commas, or schema violations. Native structured outputs guarantee syntactic validity and schema adherence at the decoding level, making regex-based extraction and 'please output valid JSON' begging obsolete and brittle.
