@ai-sdk/open-responses: convertToOpenResponsesInput silently drops assistant reasoning parts (asymmetric round trip)

Important limitations

• This may be one public report, not widespread demand.
• Current independent report count: 1.
• This is currently a single independent report. It has not passed clustering or human review as a verified signal.
• No market size, willingness to pay, competition, or trend claims are inferred here.

What was reported

Who is affected

Application developer using the reported software

Job to be done

Configure an application runtime reliably

Workflow

- The report's `baseURL` setting is not part of the current provider configuration; the defect still reproduced using the documented required `name` and `url` settings, ruling out configuration mismatch.

Desired outcome

const REASONING = 'REASONING THAT MUST SURVIVE THE ROUND TRIP';

Severity

Not enough evidence yet.

Urgency

Not enough evidence yet.

Evidence indicators

What would upgrade this

• Additional independent reports from distinct communities or authors.
• Human clustering into a review signal, then explicit publication approval.
• Counter-evidence review and durable original-source verification.
