Our AI Overview fields

result.aioverview is null when Google didn't show one, otherwise an object with:

markdown (with include.aioverview.markdown: true) and the plain answer text.
sources: the source rail, each with position, url, label, description and, when Google served it as a redirect, redirectLink.
citationPills: the inline citation chips, one entry per (pill, source) pair sharing a citationPillId, each with label, url, domain and position in sources.
relatedLinks: a chip's "View related links" items that aren't in sources, grouped by the same citationPillId.

Full definitions are in the API reference and the OpenAPI document.
