search_model_queries field/metadata-search-model-queries

What it is

The metadata field that contains the fan-out search queries. In earlier model phases (GPT-5.3/5.4) it disappeared from the final conversation object and could only be obtained via the Responses API or the SSE stream. For us it is back in the metadata in the messages format and at the same time in the stream (har.sse_event_types). The extractor reads the fan-outs from the web.run tool call (pipe syntax), not from this field alone — both stay recorded so a disappearance is noticed.

For visibility

The place where the candidate list becomes visible. What is here is what ChatGPT puts to the web as a query, before it evaluates. For visibility the phrasing of these queries counts more than any later evaluation — see Query fan-out.

• The field appeared as „new" in the messages format on 21 Aug but was already present in the stream before. Did it ever disappear from both places, or only from the final object?
