OptionalfailureList of the upsert status of each item sent in the request.
OptionalgraphSet when the context was stored (and is fully searchable via vector/keyword) but NOT graph-indexed because the knowledge base is over its per-KB graph chunk cap. Only GraphRAG coverage is absent; the singular counterpart of UpsertKnowledgeBaseContextsResponse.graphIndexingSkippedContextIds.
OptionalimageTotal number of failed images, which exceeds imageFailures.length when the list was capped.
OptionalimageFirst images (capped) the context lacks a description for because describing them failed; the context
is otherwise fully ingested. Absent when every image succeeded. imageFailureCount is the total.
